      1 E2fsprogs 1.41.11 (March 14, 2010)
      2 ==================================
      3 
      4 E2fsck will no longer give a fatal error and abort if the physical
      5 device has been resized beyond 2**32 blocks.  (Addresses Launchpad
      6 Bug: #521648)
      7 
      8 Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
      9 the allocation status of the block <blk>.  (Addresses Debian Bug:
     10 #564084)
     11     
     12 E2fsck now prints a much more emphatic and hopefully scary message
     13 when a file system is detected as mounted while doing a read/write
     14 check of the filesystem.  Hopefully this will dissuade users from
     15 thinking, "surely that message doesn't apply to *me*" :-(
     16 
     17 E2fsck -n will now always open the file system read-only.  We now
     18 disallow certain combination of options which previously were manual
     19 exceptions; this is bad because it causes users to think they are
     20 smarter than they really are.  So "-n -c", "-n -l", "-n -L", and "-n
     21 -D" are no longer supported.  (Addresses Launchpad Bug: #537483)
     22     
     23 In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
     24 it detected a badly aligned partition.  Unfortunately, this broke some
     25 distribution installation scripts, so it now just prints the warning
     26 message and proceeds.  (Addresses Red Hat Bug: #569021. Addresses
     27 Launchpad Bug: #530071)
     28     
     29 Mke2fs would take a long time to create very large journal files for
     30 ext4.  This was caused by a bug in ext2fs_block_iterate2(), which is
     31 now fixed.
     32 
     33 E2fsck now understands the EOFBLOCKS_FL flag which will be used in
     34 2.6.34 kernels to make e2fsck not complain about blocks deliberately
     35 fallocated() beyond an inode's i_size.
     36 
     37 E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
     38 e2fsck -fD can corrupt non-indexed directories when are exists one or
     39 more file names which alphabetically sort before ".".  This can happen
     40 with ext2 filesystems or for small directories (take less than a lock)
     41 which contain filenames that begin with a space or some other
     42 punctuation mark.  (Addresses Debian Bug: #573923, Addresses Launchpad
     43 Bug: #525114)
     44 
     45 
     46 Programmer's Notes
     47 ------------------
     48 
     49 Add new test, f_rehash_dir, which checks to make sure e2fsck -D works
     50 correctly.
     51     
     52 The libcom_err function now has support for Heimdal's com_right_r
     53 function().  (Addresses Sourceforge Bug: #2963865, Addresses Debian
     54 Bug: #558910)
     55     
     56 
     57 E2fsprogs 1.41.10 (February 7, 2010)
     58 ====================================
     59 
     60 Fix resize2fs bug which causes it to access invalid memory.
     61 
     62 Add libss support for libreadline.so.6.
     63     
     64 Fix e2fsck's check for extent-mapped directory with an incorrect file
     65 type.
     66 
     67 Add new e2fsck.conf configuration option, default/broken_system_clock
     68 to support systems with broken CMOS hardware clocks.  Also, since too
     69 many distributions seem to have broken virtualization scripts now,
     70 e2fsck will by default accept dates which are off by up to 24 hours by
     71 default.  (Addresses Debian Bugs: #559776, #557636)
     72 
     73 Fix a bug where mke2fs may not use the best placement of the inode
     74 table when there is only room for a single block group in the last
     75 flex_bg.
     76 
     77 E2fsck is now smarter when it needs to allocate blocks in the course
     78 of fixing file system problems.  This reduces the number of spurious
     79 differences found in pass #5.
     80 
     81 E2fsck will no longer rehash directories which fit in a single
     82 directory block.
     83 
     84 E2fsck now correctly handles holes in extent-mapped directories (i.e.,
     85 sparse directories which use extents).
     86 
     87 Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
     88 
     89 Fix a bug in filefrag where on platforms which can allow file systems
     90 with 8k blocks, that it doesn't core dump when it sees a file system
     91 with 8k block sizes.  (Thanks to Mikulas Patocka for pointing this
     92 out.)
     93 
     94 E2fsck will correctly fix directories that are have an inaccurate
     95 i_size as well as other problems in a single pass, instead of
     96 requiring two e2fsck runs before the file system is fully fixed.
     97 
     98 Fix e2fsck so it will correctly find and detect duplicate directory
     99 entries for non-indexed directories.  ( Addresses Sourceforge Bug:
    100 #2862551)
    101     
    102 Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or
    103 thinly-provisioned storage device.  This can be disabled using the -K
    104 option.
    105 
    106 Enhance libext2fs so it works around bug in Linux version 2.6.19
    107 and earlier where the /proc/swaps file was missing the header on
    108 the first line.
    109 
    110 Fix bug in Linux version 2.6.19 and earlier where the /proc/swaps file
    111 was missing the header on the first line.
    112 
    113 Fix some big-endian bugs in e2fsck and libext2fs.
    114 
    115 Fix resize2fs so it works correctly on file systems with external
    116 journals instead of failing early with the error "Illegal inode
    117 number".
    118 
    119 Fix libss so that it does not seg fault when using a readline library
    120 which does not supply a readline_shutdown() function.
    121 
    122 Updated dumpe2fs's usage message so it correctly gives the right
    123 arguments summary for "-o superblock=<num>" and "-o blocksize=<num>".
    124 (Addresses Launchpad Bug: #448099)
    125    
    126 Teach libext2fs to ignore the high 32 bits of the i_blocks field
    127 when huge_file file system feature is set, but the inode does not
    128 have the HUGE_FILE_FL flag set.
    129 
    130 Fix e2fsck's handling of 64-bit i_blocks fields.
    131 
    132 E2fsck will now print "Illegal indirect block", "Illegal
    133 double-indirect block", etc., instead of "Illegal block #-1" or
    134 "Illegal block #-2", etc.  This makes it easier for users to
    135 understand what has gone wrong.  (Addresses SourceForge Bug: #2871782)
    136 
    137 Mke2fs now will obtain get device topology information from blkid and
    138 use it to populate the superblock stride and stripe sizes.  It will
    139 also warn if the block device is misaligned
    140 
    141 Fix file descriptor leaks in fsck and debugfs.  (Addresses Novell Bug:
    142 ##524526)
    143 
    144 Fix the libext2fs library code to round up the bitmap size to a 4-byte
    145 boundary, to prevent spurious seg faults caused by the x86
    146 architecture.  This doesn't affect Linux systems, but was a major
    147 problem on a number of *BSD systems.  (Addresses Sourceforge Bug:
    148 #2328708)
    149 
    150 Fix resize2fs's minimum size required for a file system so it doesn't
    151 fail when "resize2fs -M" is run.  (Addresses RedHat Bugzilla: #519131)
    152     
    153 Dumpe2fs now prints summary information about the contents of the
    154 journal.
    155     
    156 Avoid printing scary error messages when e2fsck starts running
    157 problems on low-memory systems, as it tends to panic and mislead the
    158 user.  (Addresses Debian Bug: #509529)
    159 
    160 Fix blkid's modules.dep parser so it handles compressed (.ko.gz)
    161 modules files.  (Address Red Hat Bug: #518572)
    162     
    163 Fix tune2fs so it can add a journal when an extent-enabled file system
    164 is mounted.  (Addresses Launchpad bug: #416648)
    165 
    166 Update Czech, Indonesian, Polish and Vietnamese translations (from the
    167 Translation Project).
    168     
    169 Update/clarify man pages.  (Addresses Sourceforge Bug: #2822186)
    170 
    171 Fixed various Debian packaging issues --- see debian/changelog for
    172 details.  (Addresses Debian Bugs: #540111)
    173 
    174 Programmer's Notes
    175 ------------------
    176 
    177 The configure script supports the --with-cc, --with-ccopts, and
    178 --with-ldopts options.  Instead, the more standard use of CC=,
    179 CCFLAGS=, and LDFLAGS= in the configure command line is used instead.
    180 Also, --with-ld, which never worked, was also removed.
    181 (Addresses Sourceforge Bug: #2843248)
    182 
    183 The in-tree header files are only used if the in-tree uuid or blkid
    184 libraries are used.  Otherwise, use the system-provided uuid or blkid
    185 header files if using the system-provided libraries.
    186 
    187 Fix some build failures caused by --disable-* configure options.
    188 
    189 Work around a bug in autoconf 2.64.
    190 
    191 
    192 E2fsprogs 1.41.9 (August 22, 2009)
    193 ==================================
    194 
    195 Fix a bug in e2fsck routines for reallocating an inode table which
    196 could cause it to loop forever on an ext4 filesystem with the FLEX_BG
    197 filesystem feature with a relatively rare (and specific) filesystem
    198 corruption.  This fix causes e2fsck to try to find space for a new
    199 portion of the inode table in the containing flex_bg, and if that
    200 fails, the new portion of the inode table will be allocated in any
    201 free space available in the filesystem.
    202 
    203 Make e2fsck less annoying by only asking for permission to relocate a
    204 block group's inode table once, instead of for every overlapping
    205 block.  Similarly, only ask once to recompute the block group
    206 checksums, instead of once for each corrupted block group's checksum.
    207 
    208 Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
    209 not present, and it needs to fall back to using the FIBMAP ioctl.
    210 
    211 Fix filefrag to correctly print the number of extents for zero-length
    212 files.  (Addresses Debian Bug: #540376)
    213 
    214 Filefrag now has a -B option which forces the use of the FIBMAP ioctl
    215 to more easily debug the FIBMAP code.
    216 
    217 Fixed filefrag for non-extent based files.
    218 
    219 Add a new program, e2freefrag, which displays information about the
    220 free space fragmentation in an ext2/3/4 filesystem.
    221 
    222 Fix inode resizing via tune2fs -I so that it works correctly in the
    223 face of non-empty bad blocks inodes, and if the filesystem was
    224 formatted using the "mke2fs -E stride=N" option for RAID arrays.
    225 
    226 Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
    227 and corrupt large directories if the directory needs to shrink by more
    228 than one block.  (Addresses Debian Bug: #537510)
    229     
    230 Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
    231 last mount times are in the future, they are corrected even if
    232 buggy_init_scripts is set.  This is needed because otherwise resize2fs
    233 will refuse to resize the filesystem, even after running "e2fsck -f".
    234 (Addresses Launchpad bug: #373409)
    235 
    236 E2fsck will now print much fuller information when the last mount time
    237 or last written time is in the future, since most people can't seem to
    238 believe their distribution has buggy init scripts, or they have a
    239 failed CMOS/RTS clock battery.
    240 
    241 Enhance dumpe2fs to dump the extent information via the 'stat'
    242 command, and more detailed extent information via the new command
    243 'dump_extents'.
    244     
    245 Update French, Polish, Czech, and Sweedish translation from the
    246 Translation Project.
    247 
    248 Fixed various Debian packaging issues --- see debian/changelog for
    249 details.
    250 
    251 Programmer's Notes
    252 ------------------
    253 
    254 Fixed miscellaneous gcc -Wall warnings.
    255 
    256 Fixed memory leak in error path in ext2fs_block_iterate2()
    257 
    258 Fixed non-Linux build of the intl directory by adding support for the
    259 E/Q/V macros.
    260 
    261 The bitmap read/write functions now treat uninitialized bitmaps as
    262 unallocated; this fixes a number of problems in all e2fsprogs for ext4
    263 filesystems when there is a need to allocate new blocks or inodes, and
    264 there aren't any free blocks or inodes in the already-used block
    265 groups.
    266 
    267 Improve ext2fs_extent_set_bmap() to avoid creating new extents which
    268 get inserted into the extent tree when they are not needed.
    269     
    270 
    271 E2fsprogs 1.41.8 (July 11, 2009)
    272 ================================
    273 
    274 Fix resize2fs's online resizing, fixing a regression which in
    275 e2fpsrogs 1.41.7.   (Addresses Debian Bug: #535452)
    276 
    277 Fix potential filesystem corruptions caused by using resize2fs to
    278 shrinking ext4 filesystems with extents enabled.  (Addresses Red Hat
    279 Bug: #510379)
    280 
    281 Optimize uuid_generate() to avoid running uuidd if it is not setuid or
    282 setgid and the currently running program doesn't have write access to
    283 the uuidd work directory.
    284 
    285 Add safety checks (for non-Linux systems) so that uuidd isn't run with
    286 file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
    287 will be careful not to close the file descriptor for its unix domain
    288 socket when it detaches itself from the controlling tty.  Also add
    289 safety checks so that if the unix domain socket between the uuid
    290 library and uuidd program is closed for any reason, both the library
    291 and the uuidd will return an appropriate error code instead of looping
    292 in an infinite loop.
    293 
    294 The e2croncheck script, which creates an LVM snapshot and then checks
    295 the ext3/4 filesystem via the LVM snapshot, has been added to the
    296 contrib directory.
    297 
    298 Fix filefrag program for files that have more than 144 extents.
    299 
    300 Update French, Polish, Czech, Indonsian, and Sweedish translation from
    301 the Translation Project.
    302 
    303 Fixed various Debian packaging issues --- see debian/changelog for
    304 details.  (Addresses Debian Bug #535530)
    305 
    306 Update/clarify man pages.
    307 
    308 Programmer's Notes
    309 ------------------
    310 
    311 Fix compilation problem when configured with --disable-uuid.
    312 
    313 Don't build uuidgen if configured with --disable-uuid.
    314 
    315 Add the new library function ext2fs_test_inode_bitmap_range(), and
    316 optimized ext2fs_test_block_bitmap_range(), which will be needed for
    317 future optimizations for e2fsck.
    318 
    319 Fix makefile dependencies for libcom_err so that the Makefiles work
    320 well on non-GNU make program.  (Addresses Sourceforge Patches: #2813809)
    321 
    322 Enhance the build system so that the full set of commands executed by
    323 the Makefiles are displayed, instead of the Linux kernel summary
    324 output, if the build was configured with --enable-verbose-makecmds, or
    325 if GNU make is in use and the V variable is non-null, i.e., via "make
    326 V=1".
    327 
    328 
    329 E2fsprogs 1.41.7 (June 29, 2009)
    330 ================================
    331 
    332 Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
    333 uninitalized data into the portion of the inode beyond the first 128
    334 bytes when operating on inodes mapped via extents; potentially
    335 corrupting filesystems.
    336 
    337 Fix memory leaks in e2fsprogs, including a very large memory leak
    338 which can cause e2fsck to run out of memory when checking very large
    339 filesystems using extents.
    340 
    341 The logsave program will now filter out the ^A and ^B characters when
    342 writing to the console.
    343 
    344 Harden ext2fs_validate_entry() so that lsdel will not read beyond the
    345 end of the block even if the directory block is corrupted.
    346 
    347 Fix debugfs from core dumping if the logdump command fails to open the
    348 output file.
    349 
    350 Enhance badblocks to print the currently tested block number when
    351 interrupted with ^C.
    352 
    353 Fix lsattr to exit with a non-zero status when it encounters errors.
    354 (Addresses RedHat Bugzilla #489841)
    355 
    356 Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
    357 filesystems as the kernel when encoding rec_len >= 64k.  For 64k
    358 filesystems (currently all that is supported by e2fsprogs, this is
    359 only a minor corner case).
    360 
    361 Resize2fs will now update the journal backup fileds in the sup0erblock
    362 if the journal is moved; this avoids an unnecessary full fsck after
    363 resizing the filesystem.  (Addresses RedHat Bugzilla: #505339)
    364     
    365 Fix libext2fs to properly initialize i_extra_size when creating the
    366 journal and resize inodes.
    367 
    368 Change badblocks to allow block sizes larger than 4k.
    369 
    370 Fix filefrag progam so it correctly checks for errors from the fiemap ioctl.
    371 
    372 Update Chinese and Czech translation from the Translation Project.
    373 
    374 Clean up various man pages.  (Addresses Debian Bug #531385 and #523063)
    375 
    376 
    377 Programmer's Notes
    378 ------------------
    379 
    380 Add --disable-libuuid option to configure which uses an in-system
    381 installed version of libuuid; the private version is enabled by
    382 default.
    383 
    384 Add --valgrind-leakcheck option to the test_script program which runs
    385 valgrind with the appropriate options to find memory leaks.
    386 
    387 
    388 E2fsprogs 1.41.6 (May 30, 2009)
    389 ===============================
    390 
    391 Fix a critical regression in e2fsck introduced version 1.41.5 which
    392 can undo updates to the block group descriptors after a journal replay.
    393 
    394 If e2fsck receives an I/O error while replaying the journal, prompt
    395 the user whether they want to ignore the error or not; if e2fsck is
    396 run in preen mode, force fsck to abort the preen pass.
    397 
    398 Fix a bug which would cause e2fsck to core dump if the filesystem
    399 contains a corrupt extent header, and the user declines to clear the
    400 inode.  (Addresses Sourceforge Bug: #2791794)
    401     
    402 Fix e2fsck to restart only once in the case of multiple block groups
    403 which inodes in use that are in the uninitialized part of the block
    404 group's inode table.
    405 
    406 To reduce user confusion, if the /etc/mtab file is missing
    407 ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
    408 new, explicit error code to indicate this case.  This will cause
    409 e2fsck to give a clearer error message when the user is using buggy
    410 rescue CD's that don't properly set up /etc/mtab.  (Addresses Debian
    411 Bug: #527859)
    412     
    413 Fix e2fsck so that if the primary group descriptors are corrupted, but
    414 the backup superblock is entirely invalid, to go back to using (and
    415 fixing) the priary group descriptors instead of completely giving up
    416 on the filesystem.  (Addresses Debian Bug: #516820)
    417     
    418 Change e2fsck to not abort a preen pass if an inode is found to have
    419 i_file_acl_hi non-zero.  Ext3 filesystems don't care, and newer
    420 kernels (post 2.6.29) will ignore this field.  So let's fix it
    421 automatically during the preen pass instead of forcing the user to fix
    422 this up manually.  (Addresses Debian Bug: #526524)
    423     
    424 Add resource tracking for e2fsck passes 1b through 1d.
    425 
    426 Speed up e2fsck by eliminating unnecessary journal checks if the
    427 filesystem is already mounted and doesn't need recovery (since the
    428 kernel would have run the journal when the filesystem was mounted.)
    429 Also speed up e2fsck by avoiding unnecessary block group descriptor
    430 updates in ext2fs_close().
    431 
    432 Add support to chattr to migrate inodes from using direct/indirect
    433 blocks to extents.
    434 
    435 Avoid corrupting the filesystem if there is an attempt to shrink a
    436 filesystem using resize2fs smaller than posible by making
    437 ext2fs_set_bmap() more careful not to delete the old block until the
    438 new block can be inserted.  In addition, fix a bug in how the minimum
    439 size of the filesystem (plus a safety margin) is calculated, and
    440 modify resize2fs to refuse to shrink the filesystem below that minimum
    441 size without the force flag.
    442 
    443 Teach blkid to try to figure out DM device names using take advantage
    444 of information in sysfs when running on kernels (2.6.29 and later)
    445 which provide this information in /sys/block/dm-<N>/dm/name; this is
    446 much faster than scanning for the devncie number in /dev/mapper.
    447 
    448 Fix blkid to prefer /dev/mapper/<name> device names instad of the
    449 private /dev/dm-X names.
    450 
    451 Add an -a option to debugfs's close_filesys command which writes any
    452 changes to the superblock or block group descriptors to all of the
    453 backup superblock locations.
    454     
    455 Add support to the filefrag program to use the FIEMAP ioctl.
    456 
    457 Update Chinese translation from the Translation Project.
    458 
    459 Clean up various man pages.  (Addresses Red Hat Bugzilla: #502971 and
    460 Launchpad Bug: #381854)
    461

    466 Programmer's Notes
    467 ------------------
    468 
    469 Add test code to make sure e2fsck's problem.c doesn't have two problem
    470 codes assigned to duplicate values.
    471 
    472 Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
    473 (Addresses Sourceforge Bug: #2780205)
    474 
    475 Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
    476 function declaration for init_resource_track() and
    477 print_resource_track() when RESOURCE_TRACK is not defined.
    478 
    479 The test code which is used to build the tst_csum progam has been
    480 moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
    481 avoid compile problems caused by not having a prototype for
    482 ext2fs_group_desc_csum().  (Addresses Sourceforge Bug #2484331)
    483 
    484 Update the config.guess and config.sub file to the latest from the
    485 FSF, to allow e2fsprogs to build on the avr32 platform.  (Addresses
    486 Debian Bug: #528330)
    487 
    488 Add a new function, ext2fs_extent_open2(), which behaves like
    489 pext2fs_extent_open(), but uses the user-supplied inode structure
    490 when opening an extent instead of reading the inode from disk.
    491 
    492 
    493 E2fsprogs 1.41.5 (April 23, 2009)
    494 =================================
    495 
    496 Fix a number of filesystem corruption bugs in resize2fs when growing
    497 or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
    498 is not mounted).
    499 
    500 Debugfs can now set i_file_acl_high via the set_inodes_field command,
    501 and print a 64-bit file acl.  This is useful for debugging filesystem
    502 corruptions where the high bits of i_file_acl_high are set.  E2fsck
    503 will detect and fix non-zero i_file_acl_high on 32-bit filesystems
    504 since some Linux kernel versions pay attention to this field even when
    505 they shouldn't.
    506 
    507 Speed up e2fsck when checking clean filesystems by avoiding
    508 unnecessary block reads, and coalescing the block group descriptor
    509 blocks so they are read using a single read operation.
    510 
    511 The libuuid library will now close all file descriptors before running
    512 uuidd.  This avoids problems when the calling program has open sockets
    513 which then never get closed because uuidd is a long-running helper
    514 daeomn.  (Addresses Launchpad bug: #305057)
    515 
    516 In order to avoid unnecessary full filesystem checks by e2fsck after
    517 an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
    518 the backup superblocks.  (Addresses Red Hat Bugzilla: #471925)
    519 
    520 Mke2fs will avoid trying to create the journal when run in
    521 superblock-only mode (mke2fs -S), since the left-over journal in the
    522 inode table will cause mke2fs to fail.
    523 
    524 Fix a bug in libext2fs functions that check to see if a particular
    525 device or filesystem image is mounted, which would cause these
    526 functions to report that a file identical to the (relative) pathname
    527 used by a pseudo-filesystem was mounted when in fact it was not.
    528 
    529 Update Czech translation from the Translation Project.
    530 
    531 Add Chinese (simplified) translation from the Translation Project.
    532 
    533 Fix support for external journals (which was broken in e2fsprogs
    534 1.41.4).
    535 
    536 Fix a regression in debugfs where the "stat" command when no
    537 filesystem was open would cause debugfs to crash with a segmentation
    538 violation.
    539 
    540 Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
    541 used to support filesystems without a journal.  Update the blkid
    542 library so it understands this.
    543 
    544 The blkid library will remove an entry from the blkid cache
    545 representing the entire disk if partitions are found, since presuambly
    546 the device previously had no partition table, but has now transitioned
    547 to using a partition table.
    548 
    549 Add a check to mke2fs and tune2fs that the argument to the -m option
    550 (which specifies the reserved ratio) must be greater than zero.
    551 (Addresses Debian Bug: #517015)
    552 
    553 Add support for tracking the number kilobytes written to the
    554 filesystem via the superblock field s_kbytes_written.  It will be
    555 updated by the kernel as well as by e2fsprogs programs which write to
    556 the filesystem.  This is useful for tracking the wear to filesystems
    557 on Solid Sstate Drives.
    558 
    559 Fix compatibility issue in the libext2fs info file and makeinfo
    560 version 4.12.  (Addresses Red Hat Bugzilla: #481620)
    561 
    562 Update/clarify man pages.  (Addresses Debian Bug: #515693, #365619)
    563 
    564 Fixed various Debian packaging issues --- see debian/changelog for
    565 details. (Addresses Debian Bug: #506279)
    566 
    567 Programmer's Notes
    568 ------------------
    569 
    570 Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
    571 Bug: #521602)
    572 
    573 Fix various gcc compilation warnings and other programming cleanups.
    574 (Addresses Red Hat Bugzilla: #486997)
    575 
    576 Add support for building the blkid command statically.
    577 
    578 Add support for disabling the built-in blkid library in favor of a
    579 system-installed blkid implementation via the configure option
    580 --disable-libblkid.
    581 
    582 
    583 E2fsprogs 1.41.4 (January 27, 2009)
    584 ===================================
    585 
    586 Fixed a bug which could sometimes cause blkid to return an exit value
    587 of zero for a non-existent device (Addresses Debian Bug: #502541)
    588 
    589 Blkid will now recognize ext3 filesystems that have the test_fs flag
    590 set as ext3 filesystems.
    591 
    592 The blkid library will now recognize btrfs filesystems and swap
    593 devices currently used by user-level software suspend.
    594 
    595 Tune2fs now updates the block group checksums when changing the UUID
    596 to avoid causing e2fsck to complain vociferously at the next reboot.
    597 
    598 Tune2fs's inode size resizing algorithms have been fixed so it is not
    599 vastly inefficient for moderate-to-large filesystems, due to some
    600 O(n**2) and O(n*m) algorithms that didn't scale well at all.
    601 
    602 Fix tune2fs's inode resizing algorithm so it will not corrupt
    603 filesystems laid out for RAID filesystems; in addition, tune2fs will
    604 refuse to change the inode size for filesystems that have the flex_bg
    605 feature enabled.  (This is a limitation in the current implementation
    606 of tune2fs -I.)
    607 
    608 E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
    609 filesystems with 32-bit block numbers, when the headers for 64-bit
    610 block numbers was added.  This regression has been fixed.
    611 
    612 Debugfs's ncheck command has been fixed to avoid printing garbage
    613 characters at the end of file names.
    614 
    615 Fix resize2fs for ext4 filesystems.  Some blocks that that need moving
    616 when shrinking filesystems with uninit_bg feature would not be moved.
    617 In addition, blocks and inode table blocks were not being correctly
    618 freed when shrinking filesystems with the flex_bg feable, which caused
    619 resize2fs -M to fail.  Finally, when blocks are moved, make sure the
    620 uninitialized flag in extents is preserved.
    621 
    622 Fix bug which caused dumpe2fs to abort with an error if run on a
    623 filesystem that contained an external journal.
    624 
    625 Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
    626 for this in argv[0] to provide better legacy support for these
    627 distributions.  This is a practice that should NOT be continued,
    628 however.
    629 
    630 Mke2fs now has a new option -U, which allows the user to specify the
    631 UUID that should be used for the new filesystem.
    632 
    633 Mke2fs will treat devices that are exactly 16TB as if they were 16TB
    634 minus one block.  This allows users who have read that ext3 supports
    635 up to 16TB filesystems and who create a 16TB LVM to not get confused,
    636 since the true limit is really 16TB minus one block.
    637 
    638 E2fsck will no longer abort an fsck run if block group has an errant
    639 INODE_UNINIT flag.
    640 
    641 E2fsck now distinguishes between fragmented directories and fragmented
    642 files in verbose mode statistics and in the fragcheck report.
    643 
    644 Fix a bug in e2fsck which casued it double count non-contiguous
    645 extent-based inodes.
    646 
    647 E2fsck will leave some slack space when repacking directories to allow
    648 room for a few directory entries to be added without causing leaf
    649 nodes to be split right away.
    650 
    651 Fix a bug which caused e2fsck to crash when it comes across a
    652 corrupted interior node in an extent tree with the error message:
    653 "Error1: Corrupt extent header on inode XXXXXX"
    654 
    655 E2fsck problem descriptions involving the journal are no longer
    656 referred to as "ext3" problems, since ext4 filesystems also have
    657 journals.
    658 
    659 Fix a long-standing bug in e2fsck which would cause it to crash when
    660 replying journals for filesystems with block sizes greater than 8k.
    661 
    662 Update Catalan translation from the Translation Project.
    663 
    664 Fixed various Debian packaging issues --- see debian/changelog for
    665 details. (Addresses Debian Bugs: #503057, #502323, #511207)
    666 
    667 Programmer's Notes
    668 ------------------
    669 
    670 Fix build of e2fsck.profiled, and add support for building profiled
    671 binaries in the misc directory if configured with --enable-profile.
    672 
    673 The ext2fs_open() function now performs more sanity checks on the
    674 superblock to avoid potential divide by zero errors by other parts of
    675 library.
    676 
    677 The ext2fs_read_inode_full() function now has a safety check to avoid
    678 a segmentation fault on corrupted filesystems.
    679 
    680 The ext2fs_new_inode() function now has a sanity check so that if the
    681 s_first_inode field in the superblock is insane, it will return
    682 EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
    683 
    684 To avoid segmentation faults, ext2fs_block_alloc_stats() and
    685 ext2fs_inode_alloc_stats() now validates the passed inode or block
    686 number to avoid overrunning an array boundary.
    687 
    688 Various signed/unsigned errors for variables containing block numbers
    689 have been fixed.
    690 
    691 Accomodations for gcc's stupidity in not realizing that constant
    692 strings that do not contain a '%' character are safe to use in format
    693 strings have been made so that distributions that want to compile
    694 e2fsprogs with -Werror=format-security have an easier time doing so.
    695 
    696 Added a new 64-bit getsize interface, ext2fs_get_device_size2().
    697 
    698 Added the utility make-sparse.c to the contrib directory.
    699 
    700 The ext2fs_block_iterate2() function now reflects errors from
    701 ext2fs_extent_set_bmap() to the caller, if the callback tries to
    702 change a block on an extent-based file, and ext2fs_extent_set_bmap()
    703 fails for some reason (for example, there isn't enough disk space to
    704 split a node and expand the extent tree.
    705 
    706 The ext2fs_block_iterate2() function will preserve the uninit flag in
    707 extents when the callback function modifies a block in an extent-based
    708 file.
    709 
    710 E2fsck will now flag filesystems that have an insane s_first_ino field
    711 in their superblock, and attempt to use a backup superblock to repair
    712 the filesystem.
    713 
    714 
    715 E2fsprogs 1.41.3 (October 12, 2008)
    716 ===================================
    717 
    718 E2fsck has been fixed so it prints the correct inode number for
    719 uinit_bg related problems.
    720 
    721 E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
    722 is available on linux.  This can be disabled via a configuration
    723 option in /etc/e2fsck.conf.
    724 
    725 Fix a file descriptor leak in libblkid when checking to see if an ext4
    726 or ext4dev module exists.
    727 
    728 Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
    729 while trying to close a filesystem can lead to infinite loops.
    730 (Addresses Red Hat Bugzilla #465679)
    731     
    732 Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
    733 will cause resize2fs to drop into an infinite loop.  (Addresses Red
    734 Hat Bugzilla: #465984)
    735     
    736 Add a check in the Unix I/O functions in libext2fs so that when a
    737 device is opened read/write, return an error if the device is
    738 read-only using the BLKROGET ioctl.
    739 
    740 Fix debugfs's ncheck command so that it prints all of the names of
    741 hardlinks in the same directory.
    742 
    743 Fix a bug in libblkid so it correctly detects whether the ext4 and
    744 ext4dev filesystems are available, so that the ext4dev->ext4
    745 fallback code works correctly.
    746 
    747 Programmer's Notes
    748 ------------------
    749 
    750 Fix a parallel build problem by making sure util/subst is built before
    751 trying to build the lib/et directory.  (Addresses Sourceforge Bug:
    752 #2143281)
    753 
    754 Updated "make depend" information for crc16.o
    755     
    756 
    757 E2fsprogs 1.41.2 (October 2, 2008)
    758 ==================================
    759 
    760 Fix e2fsck's automatic blocksize detection.  This fixes a regression
    761 from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
    762 specifies a block number using the -b option if the blocksize option
    763 isn't also specified using -B.  Unfortunately, users very commonly
    764 invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
    765 superblock; in fack e2fsck will often suggest this kind of command
    766 line.  Oops.
    767 
    768 Enhance the debugfs's "ncheck" command so it will print all of the
    769 pathnames for the specified inodes.  (Previously, in some cases ncheck
    770 might not print a pathname for an inode at all if some of the other
    771 inodes had multiple hard links.)
    772 
    773 Enhance debugfs's "hash" command so the hash seed can be specified via
    774 a command-line option.  In addition, allow the hash algorithm to be
    775 specified by name instead of just by number.
    776 
    777 Fix e2fsck so that we don't accidentally print the translation file's
    778 header when asking the user a custom question so there is no prompt
    779 defined for a particular problem record.  For example, the question
    780 "Run journal anyway" will get the PO header tacked on because e2fsck
    781 erroneously passed the null string to _().  (Addresses Launchpad Bug:
    782 #246892)
    783 
    784 Enhance badblocks so that it can test a normal file which is greater
    785 than 2GB.
    786 
    787 Enhance the badblocks command so that it displays the time and
    788 percentage complete when in verbose mode.  (Addresses Debian Bug:
    789 #429739)
    790 
    791 Fix a potential memory leak in a error handling path in debugfs's
    792 ncheck function.
    793 
    794 Fix a potential memory corruption problem if a memory allocation fails
    795 in resize2fs.
    796 
    797 Fix the usage message for debugfs's logdump command to be consistent
    798 with its man manpage.
    799 
    800 Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
    801 and Sweedish translation from the Translation Project.
    802 
    803 Add documentation for the file I/O functions to the libext2fs.texinfo
    804 file.  (Addresses Debian Bug: #484877)

    812 Programmer's Notes
    813 ------------------
    814 
    815 Fix a potential file descriptor leack in libcom_err by setting the
    816 close-on-exec flag for a fd used for debugging.  (Addresses Red Hat
    817 Bugzilla #464689)
    818 
    819 Fix a potential race in libcom_err by using sem_post/sem_init.  SuSE
    820 has been carrying a patch for a long time to prevent a largely
    821 theoretical race condition if a multi-threaded application adds and
    822 removes error tables in multiple threads.  Unfortunately SuSE's
    823 approach breaks compatibility by forcing applications to link and
    824 compile with the -pthread option; using pthread mutexes has
    825 historically been problematic.  We fix this by using sem_post/sem_init
    826 instead.

    840 to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
    841 instead.  (Addresses Sourceforge Bug: #2089537)
    842     
    843 Make sure ext2fs_swab64() is compiled for all platforms, and not just
    844 for x86.  (Addresses Debian Bug: #497515)
    845     
    846 Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
    847 non-x86 platforms.  (They had been removed for x86 earlier.)
    848 
    849 Fix diet libc compilation support, which had bitrotted due to lack of
    850 TLC.  Fixing this improves general portability.
    851 
    852 When installing the link library when using ELF shared libraries,
    853 avoid using absolute pathnames if the link library and the shared
    854 library are installed in the same directory.  (Addresses Sourceforge
    855 Bug: #1782913)
    856 
    857 Fix gen-tarball so it will work even if the top-level directory has
    858 been renamed to something other than "e2fsprogs".  Also make
    859 gen-tarball print the size of the resulting tar.gz file.

    862 E2fsprogs 1.41.1 (September 1, 2008)
    863 ====================================
    864 
    865 Many people are forgetting to update their mke2fs.conf file, and this
    866 causes ext3, ext4, and ext4dev filesystems won't get created with the
    867 proper features enabled.  We address this in two ways.  First, mke2fs
    868 will issue a warning if there is not definition for an ext3, ext4, or
    869 ext4dev filesystem and the user is trying to create such a filesystem
    870 type.  Secondly, when installing from a source build, "make install"
    871 will provide basic configuration file handling for /etc/mke2fs.conf.
    872 If it exists, and does not mention ext4dev, it will be moved aside to
    873 /etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
    874 be installed.  If the existing /etc/mke2fs.conf file does mention
    875 ext4dev, then "make install" will install official mke2fs.conf file as
    876 /etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
    877 they should look to see if any changes need to be merged.
    878 
    879 The mke2fs program will now create the journal in the middle of the
    880 filesystem, since this minimizes seek times on average for fsync-heavy
    881 workloads.  In addition, mke2fs will now create journals using extents
    882 for filesystems that support them.  This results in a more efficient
    883 encoding for the journal since it eliminates the need for using
    884 indirect blocks.
    885 
    886 The mke2fs program will avoid allocating an extra block to the
    887 journal.  (Addresses Sourceforge Bug: #1483791)
    888 
    889 Mke2fs will correctly enforce the prohibition against features
    890 (specifically read-only features) in revision 0 filesystems.  (Thanks
    891 to Benno Schulenberg for noticing this problem.)
    892 
    893 Mke2fs previously would occasionaly create some slightly non-optimally
    894 placed inode tables; this bug has been fixed.
    895 
    896 The mke2fs and tune2fs programs now print the correct usage message
    897 describing the maximum journal size.  (Addresses Debian Bug: #491620)
    898 
    899 Add support for setting the default hash algorithm used in b-tree
    900 directories in tune2fs (from a command-line option) or mke2fs (via
    901 mke2fs.conf).  In addition, change the default hash algorithm to
    902 half_md4, since it is faster and better.
    903 
    904 The blkid library will now recognize MacOS hfsx filesystems, and
    905 correctly extract the label and uuid for hfs, hfsx, and hfsplus
    906 filesystems.  (Addresses Sourceforge Feature Requests: #2060292)
    907 
    908 The blkid library has improved detection of JFS and HPFS filesystems.
    909 (Addresses Launchpad Bug: #255255)
    910 
    911 The blkid library is now much more efficiently handling devicemapper
    912 devices, mainly by no longer using the devicemapper library.  This can
    913 speed up access for systems with a large number of device mapper
    914 devices.
    915 
    916 Blkid had a number of cache validation bugs in libblkid that have been
    917 fixed.   (Addresses Debian Bug: #493216)
    918 
    919 Resize2fs will now properly close out the "updating inode references"
    920 progress bar so there is a newline printed before printing the final
    921 "resize is successful" message.
    922 
    923 Resize2fs will now correctly handle filesystems with extents and/o
    924 uninitialized block groups correctly when file/directory blocks need
    925 to relocated (i.e., when shrinking a filesystem or if the resize_inode
    926 is not present).  To support this, the ext2fs library now supports
    927 initializing inode and block bitmaps that are not yet initialized when
    928 allocating them using ext2fs_new_block() and ext2fs_new_inode().  In
    929 addition, e2fs_block_iterate2() can now support changing the location
    930 of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
    931 been optimized to avoid creating unnecessary new extents when updating
    932 the location of blocks in the extent tree.  This will also help out
    933 e2fsck's recovery of obscurely corrupted filesystems with extents,
    934 when blocks are claimed by multiple inodes.
    935 
    936 Add support for on-line resizing ext4 filesystem with the flex_bg
    937 filesystem feature.  The method for doing so is not optimal, but to do
    938 a better job will require kernel support.
    939 
    940 E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
    941 debugfs programs to not be able to read e2image files; the signed
    942 vs. unsigned bug in the code which read bitmaps from the e2image has
    943 been fixed.   (Addresses Debian Bug: #495830)
    944 
    945 Resize2fs is now correctly managing the directory in-use counts when
    946 shrinking filesystems and directory inodes needed to be moved from one
    947 block group to another.  This bug has been around since e2fsprogs
    948 1.26, and is largely harmless, but does cause a filesystem corruption
    949 which will be flagged by e2fsck after the filesystem has been shrunk.
    950  
    951 E2fsck will no longer issue spurious complaints about the inode size
    952 caused by very large extent-based files, and by blocks reallocated
    953 using fallocate() with the FALLOC_FL_KEEP_SIZE option.  (Addresses
    954 Kernel Bugzilla: #11341)
    955 
    956 Mke2fs will now set the creation timestamp on the lost+found directory
    957 and the root directory.  (More generally, all new inodes created using
    958 the ext2fs library will correctly set the creation timestamp.)
    959 
    960 E2fsck now correctly calculates ind/dind/tind statistics in the
    961 presence of extent-based files.  In addition, "e2fsck -v" will report
    962 statistics of the depth of extent trees in the filesystem.  E2fsck can
    963 also give an inode fragmentation report using "e2fsck -E fragcheck"
    964 which can be useful when debugging the kernel block allocation
    965 routines.
    966 
    967 Fix support for empty directory blocks in ext4 filesystems with 64k
    968 blocksize filesystems.
    969 
    970 E2fsck will now print the depth of corrupt htree directories.
    971 
    972 Debugfs's htree command now correctly understands extent-based
    973 directories.  It will also print out the minor hash as well as the
    974 major hash.
    975 
    976 Debugfs has a new command which will print the supported features of
    977 e2fsprogs, to enable scripts to know whether the installed version of
    978 e2fsprogs can support a specific feature.
    979 
    980 Debugfs will now write files using extents for filesystems that
    981 support them.
    982 
    983 The error message printed by "tune2fs -I" if the inode size was too
    984 small was rather confusing, so it has been improved.  Also, we won't
    985 try to create an undo log until we know that command-line-specified
    986 parameters such as "tune2fs -I <inode size>" are valid.
    987 
    988 Given some filesystems found "in the wild" that had non-zero block
    989 group checksums even though the uninit_bg/gdt_sum feature was not
    990 enabled, e2fsck would issue spurious error messages.  Teach
    991 ext2fs_group_desc_csum_verify() to ignore the block group checksum
    992 entirely if the feature flag is not set.  (Addresses Debian Bug:
    993 #490637)
    994 
    995 The blkid program will now print out a user-friendly listing of all of
    996 the block devices in the system and what they contain when given the
    997 -L option.  (Addresses Debian Bug: #490527)
    998 
    999 The filefrag program now has a more accurate calculation for the
   1000 number of ideal extents.  (Addresses Debian Bug: #458306)
   1001 
   1002 The test I/O manager is now enabled by default, but its overhead is
   1003 only incurred when it would be enabled via the TEST_IO_FLAGS or
   1004 TEST_IO_BLOCK environment variables.
   1005 
   1006 Typographical errors in various program strings and usage messages
   1007 have been fixed; most of these were pointed out by the e2fsprogs
   1008 message catalog translators.  (Thanks, translators!)
   1009 
   1010 Update and clarified various man pages, as well as some typographical
   1011 errors in the libext2fs texinfo file.
   1012 
   1013 Fixed various Debian packaging issues --- see debian/changelog for
   1014 details.
   1015 
   1016 Add Indonesian and update French, Polish, Dutch, German, Sweedish,
   1017 Czech, and Vietnamese Translations.  (Addresses Debian Bugs: #313697,
   1018 #401092)

   1020 Programmer's Notes
   1021 ------------------
   1022 
   1023 Fix portability problem with the badblocks group; for systems that
   1024 don't have nanosleep(), try using usleep() instead.
   1025 
   1026 The "make check" target in the e2fsck directory now sets
   1027 LD_LIBRARY_PATH before running the various e2fsck internal library
   1028 regression tests.
   1029 
   1030 The crc32 regression test in the e2fsck library is now portable to
   1031 greater varienty of environments, including big-endian systems and
   1032 when cross-building e2fsprogs for embedded systems.  (Addresses
   1033 Sourceforge Bug: #2019287)
   1034 
   1035 The ext2fs_extent_set_bmap() had some bugs when setting the first
   1036 block in a file, or when replacing a single block extent.  Those cases
   1037 fortunately were came up relatively rarely when e2fsck was checking
   1038 files, but caused some problems when resize2fs was shrinking
   1039 extent-based files.
   1040 
   1041 Fix a potential core-dumping bug in libe2p's iterate_on_dir()
   1042 function.
   1043 
   1044 Various ext2fs library functions --- ext2fs_block_iterate2(),
   1045 ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
   1046 allocated memory to avoid memory leaks in all of their error return
   1047 paths.
   1048 
   1049 Ext2ed was failing to build because masix support had been removed in
   1050 the rest of e2fsprogs, so ext2ed no longer has masix support, either.
   1051 
   1052 The configure script now respects the LDFLAGS environment variable if
   1053 it is set when configure is called.  (Addresses Sourceforge Feature
   1054 Request: #1937287)
   1055 
   1056 Libuuid is now more portable to the Windows platform.  (Addresses
   1057 Sourceforge Feature Request: #1937287)
   1058 
   1059 The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
   1060 bare echo commands so that configure flags such as --quiet work
   1061 correctly.  (Addresses Sourceforge Patches: #2058794)
   1062 
   1063 A few uses of sprintf have been removed from the ext2fs library to
   1064 make life easier for bootloaders with a limited libc environment.
   1065 (Addresses Sourceforge Bug: #2049120)
   1066 
   1067 The ext2fs_read_inode() checks the validity of the inode number passed
   1068 to it earlier, to avoid doing some needless work when it would fail
   1069 anyway.
   1070 
   1071 The ext2fs_open() checks the validity of the blocksize parameter
   1072 passed to it earlier, to avoid doing some needless work when it would
   1073 fail anyway.
   1074 
   1075 Disable a very annoying automatic "%.sh -> %" GNU make rule in the
   1076 top-level Makefile.  That automatic rule is used to better support
   1077 SCCS, but it caused problems for a particular niche distribution which
   1078 likes to use configure.sh files to store the configure options used to
   1079 build a package.  Unfortuntaely GNU make will use the configure.sh to
   1080 replace the configure script, resulting in a self-inflicted fork bomb
   1081 leading to an out-of-memory crash.
   1082 
   1083 To support old GNU C compilers don't use C99/C++ comments, but only
   1084 K&R style comments, and don't try to use __builtin_expect if __GNUC__
   1085 is less than 3.  (__builtin_expect is only supported for gcc versions
   1086 2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
   1087 this is an optimization, we only try to use __builtin_expect for gcc 3
   1088 and up.)
   1089 
   1090 In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
   1091 __LITTLE_ENDIAN, which are only defined by glibc's header files and
   1092 hence isn't portable.
   1093 
   1094 For the convenience for some distributions that need a static tune2fs,
   1095 the Makefile for misc/ now has a tune2fs.static target.
   1096 
   1097 The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
   1098 for extent-based files
   1099 
   1100 The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
   1101 files.
   1102 
   1103 All source files no longer have any trailing white space.
   1104 
   1105 The io_channel_read_blk64() and io_channel_write_blk64() functions are
   1106 now functions instead of C preprocessor macros to provide better
   1107 forward compatibility.
   1108 
   1109 The e2fpsrogs translation template now expands the @x abbrevation.
   1110 
   1111 Various namespace leackages in libblkid, libe2p, and libext2fs have
   1112 been fixed.
   1113 
   1114 Fix a parallel build problem in e2fsprogs.
   1115 
   1116 E2fsprogs is now more portable to Solaris.
   1117   * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
   1118     are always present.
   1119   * Scripts do not assume that /bin/true is always in /bin
   1120   * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
   1121   * Flush stdio handles before calling setbuf(), since Solaris will
   1122     discard any pending output to the stream.
   1123   * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
   1124     picky about which C compiler can beused for SUSv3 conformance.
   1125     Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
   1126     and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
   1127     Since we need some SUSv3 functions, consistently use SUSv3 so
   1128     that e2fsprogs will build on Solaris using c99.
   1129   * Solaris C99 does not support varargs C preprocessor macros
   1130   * Solaris header files pollute the C namespace if in/netinet.h
   1131     is included, which conflicts with e2fsprogs' use of the kmem_cache_t
   1132     typedef.
   1133   * Solaris ships with a pathetically ancient shell in /bin/sh so we
   1134     avoid the use of various more avanced shell constructs such as $().
   1135 
   1136 The "make rpm" command will now take some extra configure optiosn from
   1137 the build environment without needing to patch the source tree.
   1138 
   1139 The ext2fs_add_dir_block() function will now grow the dblist more
   1140 aggressively as an optimization to avoid copying the array too often.
   1141 
   1142 The e2fsck_write_bitmaps() will write the block and inode bitmaps
   1143 together instead of in two passes.
   1144 
   1145 
   1146 E2fsprogs 1.41 (July 10, 2008)
   1147 ==============================
   1148 
   1149 Add support for ext4 filesystem features, in particular extents,
   1150 uninit_bg, flex_bg, huge_file, and dir_nlink features.  Also add
   1151 support for checking journal checksums.  Debugfs will print new
   1152 superblock and inode fields that were defined for ext4.  For example,
   1153 the nanosecond and i_version fields of an inode, and the
   1154 s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
   1155 Note: Resize2fs doesn't currently support the combination of flex_bg
   1156 and !resize_inode.  (Addresses Debian Bug: #388452, #425477)
   1157 
   1158 Tune2fs can support migrating a filesystem from using 128 byte inodes
   1159 to 256 byte inodes, so it can take advantage of the full features of
   1160 ext4.
   1161 
   1162 Add support for "undo" support.  E2fsck and mke2fs can optionally
   1163 record an undo log which can replayed by the program e2undo.
   1164 
   1165 E2fsck could damage a filesystem by trying to relocate inode tables
   1166 due to corrupted block group descriptors, where the attempted inode
   1167 table relocation would do far more harm than good.  E2fsck has been
   1168 fixed to detect this these sorts of corrupted block group descriptors
   1169 much earlier in e2fsck processing, so it can try to use the backup
   1170 superblock and block group descriptors first.  This should be a much
   1171 better strategy for recovering these types of corrupted filesystems.
   1172 (Addresses Sourceforge Bug: #1840291)
   1173 
   1174 E2fsck will display a more understandable message when the last check
   1175 field in the superblock is in the future.  (Addresses Debian Bug:
   1176 #446005).
   1177 
   1178 E2fsck now performs more extensive and careful checks of extended
   1179 attributes stored in the inode.
   1180 
   1181 Enhance mke2fs to print a more explanatory error message when
   1182 ext2fs_get_device_size() returns EFBIG.  (Addresses Debian Bug:
   1183 #488663)
   1184 
   1185 Fix mke2fs to use a default block size of 4k when formatting an
   1186 external journal device.  This is done by using a fixed filesystem
   1187 type list that consists only of the single filesystem type "journal"
   1188 when looking up configuration keys in /etc/mke2fs.conf.  (Addresses
   1189 Debian Bug: #488663)
   1190 
   1191 Speed up how mke2fs writes the journal data blocks by writing the disk
   1192 blocks in larger chunks.
   1193 
   1194 Fix blkid handling of stale devices.  Fix a bug which could cause a
   1195 core dump while garbage collecting the blkid cache, and assure that
   1196 blkid_find_dev_with_tag() never returns a non-existent device.  Also,
   1197 if a filesystem is found at a new /dev location, eliminate any
   1198 duplicate stale entries which can not be verified.
   1199 (Addresses Debian Bugs: #487758, #487783)
   1200     
   1201 Add more paranoid checks for LVM volumes and swap partitions in
   1202 blkid's probe function, to reduce the chances of false positives.
   1203 
   1204 The mke2fs program now has a much more sophisticated system for
   1205 controlling configuration parameters of a newly created filesystem
   1206 based on a split filesystem and usage type system.  The -t option to
   1207 mke2fs was a deprecated alias to -c; it now specifies a filesystem
   1208 type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
   1209 separated usage list.  The filesystem type information and type
   1210 information is used to extract configuration parameters from the
   1211 /etc/mke2fs.conf file.
   1212 
   1213 The mke2fs program will no longer complain and request the -f option
   1214 when the user tries to create a filesystem with greater than 2**31
   1215 blocks.
   1216 
   1217 When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
   1218 adjust the mke2fs.conf file so filesystems for the Hurd are created
   1219 with a blocksize of 4096 and inode size of 128, which is all it knows
   1220 how to handle.  (Addresses Debian Bug: #471977)
   1221     
   1222 Mke2fs will always make sure that lost+found always has at least 2
   1223 blocks, even for filesystems with very large blocksizes (i.e., 64kb).
   1224 
   1225 Resize2fs will now print the minimum needed filesystem size if given
   1226 the -P option, and will resize the filesystem to the smallest possible
   1227 size if given the -M option.
   1228 
   1229 Fix resize2fs to clean up the resize_inode if all of the reserved gdt
   1230 blocks are consumed during an off-line resize.
   1231 
   1232 The "ls" command in debugfs now supports the -p option, which causes
   1233 it to quote the filenames so that spaces or tabs in directory entries
   1234 are easily visible.  (Addresses Red Hat Bugzilla: #149480; Addresses
   1235 Sourceforge Feature Request: #1201667)

   1268 Programmer's Notes
   1269 ------------------
   1270 
   1271 Factor out bitmap code in preparation for adding 64-bit new-style
   1272 bitmaps.
   1273 
   1274 Fix gcc -Wall warnings
   1275 
   1276 Fix the pkg-config files so that private librares are specified in
   1277 "Libs.private:".
   1278 
   1279 Fix the libext2fs.texinfo manual so it builds with modern versions of
   1280 texinfo.
   1281 
   1282 Silence the makefile from showing the awk command used to build the
   1283 
   1284 Clean up the badblocks group so to make it more portable and robust.
   1285 
   1286 Avoid using predictable filenames in /tmp in blkid's regression test
   1287 suite.  Also remove bashism's in the regression test script.
   1288 
   1289 If the configure script is given --with-diet-libc, don't use thread
   1290 local storage, since diet libc doesn't support TLS.  (Addresses
   1291 Sourceforge Bug: #2000654)
   1292     
   1293 Fix the blkid regression test suite to tolerate older versions of
   1294 mkswap that don't support the -U option.
   1295 
   1296 A few library routines have been converted to support 64-bit block
   1297 numbers; in particular, the I/O manager functions, the test_io,
   1298 inode_io, and unix_io managers have all be converted to support 64-bit
   1299 operation.
   1300 
   1301 Debugfs can now be extended for use by test programs.  See
   1302 lib/ext2fs/extents.c for an example for how it can be used.  The test
   1303 program links against the debugfs object files, and provides
   1304 additional commands by defining an auxiliary libss command table.
   1305 
   1306 The lazy_bg filesystem feature, which was only used by developer's
   1307 testing, has been removed since it has been largely supplanted by
   1308 uninit_bg.  This also simplifies the code.

   1315 percentage of reserved blocks.  (Addresses Debian Bug: #452639)
   1316

   1338 
   1339 E2fsprogs 1.40.10 (May 21, 2008)
   1340 ================================
   1341 
   1342 When deciding whether or not to revalidate a blkid cache entry, if the
   1343 device's mtime is newer than the last time the cached entry was
   1344 validated, force a revalidation.
   1345 
   1346 Fix a potential data corruption bug in e2fsck in the journal replay.
   1347 The chances of this is happening is extremely remote, especially the
   1348 default data=ordered or data=writeback modes.  However, if a block
   1349 which has been journalled starts with the first four bytes 0xc03b3998,
   1350 when e2fsck replays the journal, those four bytes will be replaced
   1351 with zero's.  Fortunately, it is highly, highly unlikely for e2fsck
   1352 metadata to begin with those fatal 4 byte sequence, and unless
   1353 data=ordered mode is in use, data blocks are never journaled.
   1354 
   1355 Updated German, Dutch, Sweedish, and Vietnamese translations.

   1366 
   1367 E2fsprogs 1.40.9 (April 27, 2008)
   1368 =================================
   1369 
   1370 SuSE's security team audited uuidd and came up with a few minor
   1371 issues.  None of them are serious given that uuidd runs setuid as a
   1372 unprivileged user which has no special access other than libuuid
   1373 directory, but it's good to get them fixed.
   1374 
   1375 One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
   1376 work correctly with in-inode extended attributes.
   1377 
   1378 Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
   1379 translations.
   1380 
   1381 Debugfs will avoid using a pager if the standard output is not a tty.
   1382 
   1383 Fix debugfs and tune2fs to correctly handle daylight savings time when
   1384 parsing a time string.
   1385 
   1386 Fixed spelling mistakes, typos, and otherwise clarified man pages.
   1387 
   1388 Fix fsck completion bars when multiple filesystems were being checked
   1389 in parallel.  (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
   1390 #203323, Addresses Sourceforge Bug: #1926023)
   1391 
   1392 Fix fsck so that progress information is sent back correctly when
   1393 multiple filesystems are being check and the output of fsck is being
   1394 redirected to a file descriptor.  Also, include the device name (w/o
   1395 spaces) in the progress information sent back via a file descriptor.

   1405 s_first_data_block setting.

   1408 not reported correctly.  9Addresses Launchpad Bug: #220275)
   1409 
   1410 Mke2fs will not allow the logically incorect combination of
   1411 resize_inode and meta_bg, which had previously caused mke2fs to create
   1412 a corrupt fileystem.

   1435 
   1436 
   1437 E2fsprogs 1.40.8 (March 13, 2008)
   1438 =================================
   1439 
   1440 Fixed e2image -I so it works on image files which are larger than 2GB.
   1441 
   1442 Fixed e2fsck's handling of directory inodes with a corrupt size field.  If
   1443 the size is larger than the number of blocks found in the inode, don't
   1444 try to allocate extra empty blocks at the end of the directory to make
   1445 up the difference; there's no point to doing that.  In addition, if
   1446 the size is not a multiple of a blocksize, always fix it.
   1447 
   1448 E2fsck handled a pass 2 "should never happen error" by not giving
   1449 enough information and then core dumping.  Unfortunately, it was all
   1450 too easy to trigger the "should never happen" situation if a
   1451 directory's inode size was not correct.  This has been fixed, but
   1452 e2fsck has also been taught how to handle this situation more
   1453 gracefully, by simply removing the inode hash tree information, so
   1454 that it can be rebuilt again after e2fsck's pass 3.  (Addresses
   1455 Launchpad Bug: #129395)
   1456 
   1457 Resize2fs had a bug resizing large inodes with extended attributes
   1458 that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
   1459 completely on big-endian systems such as PowerPC.  The bug should be
   1460 completely fixed now.  Yay for regression test suites.  (Addresses Red
   1461 Hat Bugzilla: #434893)
   1462     
   1463 Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
   1464 translations.  Many thanks to Philipp Thomas from Novell for stepping
   1465 up to become the new German translation maintainer!  (Addresses Debian
   1466 Bugs: #302512, #370247, #401092, #412882).
   1467 
   1468 When e2fsck is clearing a corrupt inode's HTREE directory information,
   1469 make it clear that it is just clearing the HTREE information, not the
   1470 entire inode.
   1471 
   1472 Fixed spelling mistakes, typos, and otherwise clarified man pages.  
   1473 
   1474 Programmer's notes
   1475 ------------------
   1476 
   1477 Add new functions, ext2fs_dblist_get_last() and
   1478 ext2fs_dblist_drop_last(), which allows the caller to examine the last
   1479 directory block entry added to the list, and to drop if it necessary.
   1480 
   1481 Fixed a portability problem in libblkid with DJGPP.
   1482 
   1483 Fix an obvious typo in an "internal error" message in e2fsck.  Thanks
   1484 to Philipp Thomas for pointing this out.
   1485 
   1486 If the info files are not built, change "make install" so it doesn't
   1487 fail with an error code.

   1490 E2fsprogs 1.40.7 (February 28, 2008)
   1491 ====================================
   1492 
   1493 Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
   1494 depreciate the -s option, since it can result in filesystems which
   1495 e2fsck can't fix easily.  There are very good reasons for wanting to
   1496 disable sparse_super; users who wants to turn off sparse_super can use
   1497 debugfs.  (Addresses Sourceforge Bug: #1840286)
   1498     
   1499 Add missing options to mke2fs's usage message.  (Addresses Sourceforge
   1500 Bug: #1751393)
   1501     
   1502 Fix bug in resize2fs when large (greater than 128 byte) inodes are
   1503 moved when a filesystem is shrunk; it was only moving the first 128
   1504 bytes, so extended attributes were not getting moved.  (Addresses Red
   1505 Hat Bugzilla: #434893)
   1506 
   1507 E2fsck now prints an explicit message when the bad block inode is
   1508 updated, to avoid confusion about why the filesystem was modified.
   1509 (Addresses Sourceforge Bug: #756460)
   1510     
   1511 Allow mke2fs and tune2fs manipulate the large_file feature.
   1512 Previously we just let the kernel and e2fsck do this automatically,
   1513 but e2fsck will no longer automatically clear the large_file feature.
   1514 It still isn't really necessary to worry about this feature flag
   1515 explicitly, but some users seem to care.  (Addresses Red Hat Bugzilla:
   1516 #258381)
   1517     
   1518 Suppress message about an old-style fstab if the fstab file is empty.
   1519 (Addresses Debian Bug: #468176)
   1520     
   1521 Fix (really minor) bug in debugfs's find_free_block so it avoids
   1522 reporting a free block more than once if there are too few free blocks
   1523 in the filesystem.  (Addresses Sourceforge Bug: #1096315)
   1524     
   1525 Change e2fsck to no longer clear the LARGE_FILES feature flag
   1526 automatically, when there are no more > 2GB files in the filesystem.
   1527 It's been almost a decade since there have been kernels that don't
   1528 support this flag, and e2fsck clears it quietly without telling the
   1529 user why the filesystem has been changed.
   1530     
   1531 Fix bug which could cause libblkid to seg fault if a device mapper
   1532 volume disappears while it is being probed.  (Addresses RedHat
   1533 Bugzilla: #433857)
   1534     
   1535 Inhance e2fsck's reporting of unsupported filesystem feature flags.
   1536 (Addresses Sourceforge Feature Request: #1175808)
   1537     
   1538 Fix option syntax in dumpe2fs for explicit superblock and blocksize
   1539 parameters.  What was currently documented in the man page has been
   1540 broken for some time, due to getopt() implementation changes.  The
   1541 option sytax has been changed to one which is can be more portable
   1542 supported and which is consistent with the format for extended options
   1543 in mke2fs and tune2fs.  (Addresses Sourceforge Bug: #1830994)
   1544     
   1545 Add support to tune2fs to clear the resize_inode feature.  This
   1546 requires an fsck afterwards.  (Addresses Red Hat Bugzilla: #167816)
   1547 
   1548 Teach blkid to detect LVM2 physical volumes.  (Addresses Red Hat
   1549 Bugzilla: #409321)
   1550 
   1551 Add support for setting RAID stride and stripe-width via mke2fs and
   1552 tune2fs.  Teach dumpe2fs to print the RAID parameters.
   1553 
   1554 Add support for setting new superblock fields to debugfs's
   1555 set_super_value.
   1556 
   1557 Add support for printing "mostly-printable" extended attributes in
   1558 Debugfs.
   1559 
   1560 Add support for the -M option to fsck, which causes it to ignore
   1561 mounted filesystem.
   1562 
   1563 Fix uuidd so that it creates the pid file with the correct pid number.

   1579 
   1580 Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
   1581 partially filled-in filesystem object on an error, so that e2fsck can
   1582 print more intelligent error messages.
   1583     
   1584 Add a new function e2p_edit_feature2() which allows the caller to
   1585 specify which feature flags are OK to set or clear, and which returns
   1586 more specific information about feature flags which are not allowed to
   1587 be set/cleared.

   1649 E2fsprogs 1.40.5 (January 27, 2008)

   1651 
   1652 Fix a potential overflow big in e2image if the device name is too
   1653 long.
   1654 
   1655 Mke2fs will now create new filesystems with 256 byte inodes and the
   1656 ext_attr feature flag by default.  This allows for much better future
   1657 compatibity with ext4 and speeds up extended attributes even on ext3
   1658 filesystems.
   1659 
   1660 Teach e2fsck to ignore certain "safe" filesystem features which are
   1661 set automatically by the kernel.  Having the kernel set features
   1662 automagically behind the user's back is a bad idea, and we should try
   1663 to break the kernel of this habit, especially for the newer ext4
   1664 feature flags.  But for now, we will try to avoid needless full checks
   1665 which can annoy users who are doing fresh installs.
   1666 
   1667 Add support in tune2fs and mke2fs for making a filesystem as being "ok
   1668 to be used with test kernel code".  This will be needed for using test
   1669 filesystems with the latest ext4 kernel code.
   1670 
   1671 Change e2fsck -fD so that it sorts non-htree directories by inode
   1672 numbers instead of by name, since that optimizes performances much
   1673 more significantly.  (Addresses-Sourceforge-Feature-Request: #532439)
   1674 
   1675 If e2image fills the disk, fix it so it exits right away instead of
   1676 spewing large numbers of error messages.
   1677 (Addresses-Sourceforge-Feature-Request: #606508)
   1678 
   1679 If ftruncate64() is not available for resize2fs, let it use ftrucate()
   1680 instead, but have it check to see if the size would get truncated, and
   1681 skip calling ftruncate in that case.
   1682 
   1683 Add support for detecting HFS+ filesystems in the blkid library.
   1684 
   1685 Add supprt in the blkid library for ext4/ext4dev filesystems.
   1686 
   1687 Fix a bug in blkid where it could die on a floating point exception
   1688 when presented with a corrupt reiserfs image.
   1689 
   1690 Fix blkid's handling of ntfs UUID's so that leading zeros are printed
   1691 such that UUID string is a fixed length.
   1692 
   1693 Add sample python bindings for the uuid library to the contrib
   1694 directory.  (Addresses-Sourceforge-Patches: #778817)
   1695 
   1696 Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
   1697 will work with large files.  (Addresses Sourceforge Feature Request:
   1698 #1257500 and Sourceforge Support Request: #1253511)
   1699     
   1700 Allow the debugfs 'undel' command to undelete an inode without linking
   1701 it to a specific destination directory, since this might require
   1702 allocating blocks that could overwrite some yet-to-be-recovered
   1703 deleted files.  (Addresses-Sourceforge-Feature-Request: #967141)

   1739 ====================================
   1740 
   1741 Improve time-based UUID generation.  A new daemon uuidd, is started
   1742 automatically by libuuid if necessary.  This daemon is setuid to allow
   1743 updates to /var/lib/libuuid, so the clock sequence number can be
   1744 stored and so if the clock is set backwards, it can be detected.

   1747 
   1748 Filter out the NEEDS_RECOVERY feature flag when writing out the backup
   1749 superblocks.  This avoids e2fsck from concluding that a full
   1750 filesystem check is required before backing up the superblock due to
   1751 changes in the feature flags.  (Addresses Debian Bug: #454926)
   1752 
   1753 Fix fsck to only treat the '#' character as a comment at the beginning
   1754 of the line in /etc/fstab.  Otherwise fstabs for the fuse filesystem
   1755 will cause fsck to issue an bogus warning message.

   1793 E2fsprogs 1.40.3 (December 5, 2007)
   1794 ===================================
   1795 
   1796 Fix a potential security vulnerability where an untrusted filesystem
   1797 can be corrupted in such a way that a program using libext2fs will
   1798 allocate a buffer which is far too small.  This can lead to either a
   1799 crash or potentially a heap-based buffer overflow crash.  No known
   1800 exploits exist, but main concern is where an untrusted user who
   1801 possesses privileged access in a guest Xen environment could corrupt a
   1802 filesystem which is then accessed by the pygrub program, running as
   1803 root in the dom0 host environment, thus allowing the untrusted user to
   1804 gain privileged access in the host OS.  Thanks to the McAfee AVERT
   1805 Research group for reporting this issue.  (Addresses CVE-2007-5497.)
   1806 
   1807 Fix hueristics in blkid which could cause a disk without partitions to
   1808 be incorrectly skipped when a loopback device is present.  (Addresses
   1809 Red Hat Bugzilla #400321.)
   1810 
   1811 Fix e2image so that in raw mode it does not create an image file which
   1812 is one byte too large.
   1813 
   1814 Change mke2fs's usage message so it recommends the preferred -E option
   1815 instead of the deprecated -R option.
   1816 
   1817 Enhance the blkid library so it will recognize squashfs filesystems.
   1818 (Addresses Red Hat Bugzilla #305151.)
   1819 
   1820 Enhance e2fsck so it will force the backup superblocks to be backed up
   1821 if the filesystem is consistent and key constants have been changed
   1822 (i.e., by an on-line resize) or by e2fsck in the course of its
   1823 operations.
   1824 
   1825 Enhance blkid's detection of FAT filesystems; so that USB disks with
   1826 only a single bootable partition will not get missed.
   1827 
   1828 E2fsck will no longer mark a filesystem as invalid if it has time
   1829 errors (i.e., if superblock mount time or last write time is in the
   1830 future) and the user refuses to fix the problem.
   1831 
   1832 The Ubuntu init scripts don't properly set the system time correctly
   1833 from hardware clock if the hardware clock is configured to tick local
   1834 time instead of GMT time.  Work around this as best as we can by
   1835 providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
   1836 be set on Ubuntu systems.  (Addresses Debian Bug #441093, and Ubuntu
   1837 Bug #131201.)
   1838 
   1839 Fix fsck to ignore /etc/fstab entries for bind mounts.  (Addresses Red
   1840 Hat Bugzilla #151533.)
   1841 
   1842 Fix e2fsck so that if the superblock is corrupt, but still looks
   1843 vaguely like an ext2/3/4 superblock, that it automatically tries to
   1844 fall back to the backup superblock, instead of failing with a hard
   1845 error.
   1846 
   1847 Make the e2fsprogs program more robust so that they will not crash
   1848 when opening a corrupt filesystem where s_inode_size is zero.
   1849 
   1850 Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
   1851 arguments are detected as such and the parse error is reported to the
   1852 user.   (Addresses Debian Bug #435381.)
   1853 
   1854 Change e2fsck so it will not complain if a file has blocks reallocated
   1855 up to the next multiple of a system's page size.
   1856 
   1857 Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
   1858 about (valid) filesystems where the inode table extends to the last
   1859 block of the block group.  (Addresses Red Hat Bugzilla #214765.)
   1860 
   1861 Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
   1862 allocating inode tables for some relatively rare odd disk sizes.
   1863 (Addresses Red Hat Bugzilla #241767.)
   1864 
   1865 Add Catalan translation and update Dutch and Swedish translations
   1866 from the Translation Project.
   1867 
   1868 Fix big-endian byte-swapping bug in ext2fs_swap_inode_full().  We
   1869 still had an issue when trying to figure out whether we need to
   1870 byte-swap fast symlinks that contained extended attributes.
   1871

   1880 
   1881 Add "make check" to the RPM spec file
   1882 
   1883 Fix "make install" and 'make unstall" in misc/Makefile.in so that it
   1884 works correctly when the prefix is not the root directory.
   1885 
   1886 Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
   1887 clena up after themselves by deleting the test.img temporary file
   1888 after completing the test.
   1889 
   1890 Fixed a corner case bug ext2fs_unlink() when trying to delete the
   1891 first directory entry in a directory block and the last directory
   1892 entry in the previous directory block is not in use.  Fortunately
   1893 ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
   1894 places where it is extremely unlikely to run into this corner case.
   1895 
   1896 Fix missing dependency which would cuase parallel builds to fail.
   1897 (Addresses Sourceforge Bug #1842331.)
   1898

   1900 calling open(O_CREATE) with a missing mode parameter.
   1901 
   1902 Fix the test_ss.c in lib/ss so it can be used as an example
   1903 application program for the library as well as a regression test
   1904 suite.
   1905 
   1906 Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
   1907 are properly passed back up through the call stack.
   1908 
   1909 E2fsprogs 1.40.2 (July 12, 2007)
   1910 ================================
   1911 
   1912 A recent change to e2fsck_add_dir_info() to use tdb files to check
   1913 filesystems with a very large number of filesystems had a typo which
   1914 caused us to resize the wrong data structure.  This would cause a
   1915 array overrun leading to malloc pointer corruptions and segfaults.
   1916 Since we normally can very accurately predict how big the the dirinfo
   1917 array needs to be, this bug only got triggered on very badly corrupted
   1918 filesystems.
   1919 
   1920 Fix a bug in e2fsck which caused it to incorrectly salvange
   1921 directories when the last entry's rec_len is bogusly too big.  This
   1922 resulted in a nonsense filesystem corruption to be reported, and
   1923 required a second run of e2fsck to fully fix up the directory.

   1931 
   1932 E2fsprogs 1.40.1 (July 7, 2007)
   1933 ===============================
   1934 
   1935 Fix bug which could cause libblkid to loop forever.  When revalidating
   1936 a partition where there is obsolete information in /etc/blkid.tab, we
   1937 end up freeing a the type tag without clearing dev->bid_type, causing
   1938 blkid_verify() to loop forever.  (Addresses Debian Bug: #432052)
   1939     
   1940 The Turkish translation has a bug in it where it has the translation
   1941 of "E@e '%Dn' in %p (%i)" to "E@E".  This causes @E to be expanded at
   1942 @E, recursively, forever, until the stack fills up and e2fsck core
   1943 dumps.  We fix this by making e2fsck stop @-expansions after a
   1944 recursive depth of 10, which is far more than we need.
   1945 (Addresses Sourceforge Bug: #1646081)
   1946     
   1947 Compile the default mke2fs.conf into mke2fs program.  People are
   1948 getting surprised by mke2fs creating filesystems with different
   1949 defaults than earlier versions of mke2fs if mke2fs.conf is not
   1950 present.  So we now create a built in version of mke2fs.conf file
   1951 which is used by mke2fs if the /etc/mke2fs.conf is not present.
   1952 (Addresses SourceforgeBug: #1745818)
   1953 
   1954 Improve the config/parse_types.sh helper script.  Fix a potential
   1955 security problem if e2fsprogs is built as root (as Gentoo does!).  In
   1956 addition fix the script and how it is called from the configure script
   1957 so that it does the right thing when cross-compiling.  (Fixes Gentoo
   1958 bug: #146903)
   1959     
   1960 Update Vietnamese, French, and Dutch PO files from the Translation
   1961 Project.  Also created a new e2fsprogs.pot file for translator.
   1962     
   1963 Fix bogus strip permission errors when building under Debian.  When
   1964 building the e2fsprogs dpkg's, the dh_strip command emits a large
   1965 number of error messages caused by the permissions not being right.
   1966 So run dh_fixperms before running dh_strip.
   1967 
   1968 Programmer's Notes:
   1969 -------------------
   1970 
   1971 Add new function: profile_set_default().  This function sets the value
   1972 of the pseudo file "<default>".  If the file "<default>" had
   1973 previously been passed to profile_init(), then def_string parameter
   1974 will be parsed and used as the profile information for the "<default>"
   1975 file.
   1976     
   1977 Fix mk_cmds's error reporting so that it is unambiguous that it is the
   1978 mk_cmds script which is generating the error.  (Obviates Gentoo patch:
   1979 e2fsprogs-1.32-mk_cmds-cosmetic.patch)
   1980     
   1981 Fix the test suite to use LC_ALL instead of LANG.  LC_ALL is the "high
   1982 priority" environment variable that overrides all others, where as
   1983 LANG is the lowest priorty environment variable.  If LC_ALL is set, it
   1984 doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
   1985 the all the rest are set.  This will assure that the locale when
   1986 running the test suites is the "C" locale.  (Obviates Gentoo patch:
   1987 e2fsprogs-1.38-tests-locale.patch)
   1988

   1991 ==============================
   1992 
   1993 Fix divide by zero error in blkid's NTFS probing logic.
   1994 
   1995 Add new blkid -g option which causes the blkid cache to be garbage
   1996 collected.
   1997 
   1998 Fix a bug in libblkid which could cause the internal field bid_type to
   1999 become corrupted.  Fortunately bid_type isn't used much, and bid_label
   2000 and bid_uuid is only used by debugging code, so the impact of this bug
   2001 was very minor.
   2002 
   2003 Mke2fs will now store the RAID stride value when a filesystem is
   2004 created with a requested RAID stride, and then use it automatically in
   2005 resize2fs.
   2006 
   2007 Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
   2008 isn't too big.  In some cases Lustre users have tried specifying an
   2009 inode size of 4096 bytes, while keeping an inode ratio of one inode
   2010 per 4096 bytes.  
   2011 
   2012 Improve sanity check in e2fsck's algorithm for finding a backup
   2013 superblock, so that it won't accidentally find a superblock that was
   2014 located in the journal, and then later reject it as being not a valid
   2015 backup superblock.
   2016 
   2017 Fix e2fsck get_size logic so that it will work with the Linux floppy
   2018 driver.  The Linux floppy driver is a bit different from the other
   2019 block device drivers, in that if the device has been opened with
   2020 O_EXCL, it disallows another open(), even if the second open() does
   2021 not have the O_EXCL flag.  (Addresses Debian Bug: #410569)
   2022 
   2023 Fix error checking of badblock's last-block and start-block arguments.
   2024 (Addresses Debian Bug: #416477)
   2025 
   2026 Fix e2fsck so that it doesn't overwrite the backup superblocks when
   2027 recovering a journal until the master superblock has been confirmed as
   2028 being sane.
   2029 
   2030 Change the blkid library to be much more paranoid about concluding
   2031 that a partition contains an NTFS filesystem, and fetch the UUID and
   2032 LABEL information from NTFS filesystems.  (Addresses Launchpad Bug:
   2033 #110138)
   2034 
   2035 Factor out the code which sets the default journal size and move it
   2036 into libext2fs.
   2037 
   2038 Enhance e2fsck so it will recreate the ext3 journal if the original
   2039 journal inode was cleared to due it being corrupt after finishing the
   2040 filesystem check.
   2041 
   2042 Fix e2fsck so that it updates the journal inode if it is corrupted and
   2043 the backup journal information from the superblock was successfully
   2044 used to recover the filesystem.
   2045 
   2046 Fix e2fsck so that it checks all of the blocks in the journal inode
   2047 for validity.  The original code only checked the direct blocks to
   2048 make sure the journal inode was sane.  Unfortunately, if some or all
   2049 of the indirect or doubly indirect blocks were corrupted, this would
   2050 not be caught.
   2051 
   2052 Add support in blkid to detect LUKS encrypted partitions.
   2053 
   2054 Add extra sanity checks for extended attributes in the case where the
   2055 size is zero but the offset is very large.
   2056 
   2057 Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
   2058 and ext2fs_get_next_inode_full().
   2059 
   2060 Clarify the copyright licenses used by the various libraries in
   2061 the top-level COPYING  file (Red Hat Bugzilla: 166058)
   2062 
   2063 Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
   2064 
   2065 Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
   2066 
   2067 Remove check in e2fsck which requires EA's in inodes to be sorted;
   2068 they don't need to be sorted, and e2fsck was previously wrongly
   2069 clearing unsorted EA's stored in the inode structure.
   2070 
   2071 Allow mke2fs or tune2fs to create a substantially larger journal (up
   2072 to 10,240,000 blocks).
   2073 
   2074 Fix MD superblock detection, and make sure the correct UUID is
   2075 reported from the MD superblock.
   2076 
   2077 Fix a signed vs. unsigned bug in debugfs.
   2078 
   2079 Enhance debugfs's date parser so that it accepts integer values.
   2080 
   2081 Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
   2082 file with multiply claimed blocks is hard linked. or not at all if the
   2083 root directory contains shared blocks
   2084 
   2085 Enhance debugfs so it can modify the block group descriptors using the
   2086 command set_block_group_descriptor.
   2087 
   2088 Improve e2fsck's reporting of I/O errors so it's clearer what it was
   2089 trying to do when an error happens
   2090 
   2091 Fix a bug in in how e2fsprogs byte swaps inodes containing fast
   2092 symlinks that have extended attributes.  (Addresses Red Hat Bugzilla:
   2093 #232663 and LTC Bugzilla: #27634)
   2094 
   2095 Fix potential file descriptor leak in ext2fs_get_device_size() in an
   2096 error case.
   2097 
   2098 Add libreadline.so.5 support to libss.
   2099 
   2100 Impove badblocks -n/-w exclusive usage message.
   2101 
   2102 Fix dump_unused segfault in debugfs when a filesystem is not open
   2103 
   2104 Fix memory leak in blkid library.  (Addresses Debian Bug: #413661)
   2105 
   2106 Allow the debugfs lcd command to work w/o a filesystem being open.
   2107 (Addresses LTC Bugzilla #27513)
   2108 
   2109 Fix e2fsck to clear i_size for special devices with a bogus i_blocks
   2110 field on the first pass.
   2111 
   2112 Fix e2fsck to set the file type of the '..' entry when connecting
   2113 a directory to lost+found.  (Addresses Lustre Bug: #11645)
   2114 
   2115 Enhance e2fsck to recover directories whose modes field were corrupted
   2116 to look like special files.  This is probably only useful in
   2117 artificial test cases, but it will be useful if we ever do the "inodes
   2118 in directory" idea for ext4.
   2119 
   2120 Allow debugfs to dump (and rdump) > 2GB files.  (Addresses Debian Bug:
   2121 #412614)
   2122 
   2123 Fix resize2fs parsing of size parameter (in sector units).  This was
   2124 actually a bug in libe2p's parse_num_blocks() function.  When handling
   2125 the 's' suffix, it was ignoring the blocksize information passed in
   2126 from the caller and always interpreting the number in terms of a 1k
   2127 blocksize.  (Addresses Debian Bug: #408298)
   2128 
   2129 There was a floating point precision error which could cause e2fsck to
   2130 loop forever on really big filesystems with a large inode count.
   2131 (Addresses Debian Bug: #411838)
   2132 
   2133 Fix memory leak in ext2fs_write_new_inode()
   2134 
   2135 Add support for using a scratch files directory to reduce e2fsck's
   2136 emory utilization on really big filesystems.  This uses the TDB
   2137 library.  See the [scratch_files] section of the e2fsck.conf man page
   2138 for more details.
   2139 
   2140 Fixed type-punning bug which caused dumpe2fs to crash on the Arm
   2141 platform (Addresses Debian Bug: #397044)
   2142 
   2143 Add explanatory message to badblocks that -n and -w are mutually exclusive
   2144 (Addresses Debian Bug: #371869)
   2145 
   2146 Allow debugfs and dumpe2fs to support fs features under development.
   2147 
   2148 Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
   2149 ext2fs_open() , which allows application to open filesystes with features
   2150 which are currently only partially supported by e2fsprogs.
   2151 
   2152 Allow unix_io to support offsets greater than 2G (Addresses
   2153 SourceForge Bug: #1547922)
   2154 
   2155 Fixed overflow and signed/unsigned problems caused by the number of
   2156 blocks or inodes exceeding 2**31 or being close to 2**32-1.
   2157 
   2158 Add support for unsigned directory hash calculations with hints in the
   2159 superblock to fix cross-architectural portability for htree
   2160 directories with filenames where the high 8th bit is set.  (Addresses
   2161 Debian: #389772)
   2162 
   2163 Fix resize2fs so that it gives user-intelligible error messages if the
   2164 filesystem or the kernel does not support on-line resizing.
   2165 (Addresses Debian Bug: #380548)
   2166 
   2167 Require mke2fs -F -F for really dangerous operations, since -F is
   2168 needed for less dangerous operations such as creating filesystems
   2169 images in regular files, or creating filesystems on whole block
   2170 devices.  These relatively innocuous usages should NOT be confused
   2171 with running mke2fs on an apparently-mounted or in-use filesystem.
   2172 
   2173 Allow the default inode size to be specified into the mke2fs.conf
   2174 file.
   2175 
   2176 Make the smallest default journal size is big enough so that on-line
   2177 resizing should always work.
   2178 
   2179 Fix silly spelling error in e2fsck.  (Addresses SourceForge bug:
   2180 #1531372)
   2181 
   2182 Fix debugfs coredump when lsdel is run without an open filesystem
   2183 (Addresses Debian Bug: #378335)
   2184 
   2185 Fix debugfs display bug us that bytes that have the high bit set are
   2186 displayed as "ec" instead of "ffffffec".
   2187 
   2188 Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
   2189 
   2190 Device mapper scanning wasn't working in the blkid library because the
   2191 pathnames had an extra "/dev" when they were being probed.
   2192 
   2193 Add GFS/GFS2 support to the blkid library.
   2194 
   2195 Fix blkid support of empty FAT filesystem labels.
   2196 
   2197 Avoid recursing forever (or for a long time) when the blkid library
   2198 searches for a device and there are symlinks to directories in /dev.
   2199 
   2200 Avoid unaligned halfword access in blkid when accessing FAT
   2201 superblocks, as this will cause Sparc/Solaris systems to throw a
   2202 SIGBUS error.
   2203 
   2204 The latest devmapper libraries requires pthreads, add -lpthreads to
   2205 the static link libraries for e2fsck.static if devmapper is enabled.
   2206 (Addresses Debian bug: #388718)
   2207 
   2208 Improve the (non-installed, for experts only) findsuper program by
   2209 printing the uuid and label from the superblocks, as well as the
   2210 starting and ending offsets of the filesystem given the information in
   2211 the superblock.  Omit by default printing superblocks that are likely
   2212 found in located in an ext3 journal unless an explicit -j option is
   2213 given.
   2214 
   2215 Updated Spanish, French and Dutch translations and added Catalan
   2216 translation.  (Addresses Debian bug: #411562)
   2217 
   2218 Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
   2219 determining a partition's size, since binary searching to determine
   2220 the device doesn't work on FreeBSD.
   2221 
   2222 Documentation about UUID's is available in enough places, and it's
   2223 awkward to deal with debian-legal's insanities.  So I'm caving in the
   2224 "more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
   2225 don't have do the dfsg tarball.  Also remove the rule that only tried
   2226 to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
   2227 e2fsprogs exclusively from Debian.  (Addresses Debian Bug: #407107)
   2228 
   2229 Fix the info-dir line so that the menu name does not contain a .info
   2230 prefix.  First of all, it's ugly, secondly, it causes the install-info
   2231 command to fail to remove the com_err info file from the
   2232 /usr/share/info/dir file when the comerr-dev package is removed and
   2233 purged.  (Addresses Debian Bug: #401711)
   2234 
   2235 Fixed spelling mistakes, typos, and otherwise clarified man pages.
   2236 (Addresses Debian Bug: #369761, #373004, #379695)
   2237 
   2238 Fixed various Debian packaging issues --- see debian/changelog for

   2242 
   2243 Programmer's notes:
   2244 -------------------
   2245 
   2246 E2fsck now supports the %It expansion when printing a problem report.
   2247 It will print the type of the inode in the problem context.
   2248 
   2249 Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
   2250 (Addresses Sourceforge Bug: #1565561)
   2251 
   2252 Remove unused variables and other lint/gcc -Wall cleanups
   2253 
   2254 Add check to ext2fs_get_device_size() so it will return EFBIG for for
   2255 filesystems contained in regular files where the filesystem image size
   2256 is returned by stat64().
   2257 
   2258 Set local environment variables to C so mk_cmds and compile_et always
   2259 work.  (Addresses SourceForge Bug: #1532177)
   2260 
   2261 Added the 64-bit byte swapping function ext2fs_swab64().
   2262 
   2263 Added two new helper functions to prevent 2**31/2**32-1 overflow
   2264 problems: ext2fs_div_ceil() and e2p_percent().
   2265 
   2266 Create new ext2fs library inline functions ext2fs_group_first_block()
   2267 and ext2fs_group_last_block() in order to calculate the starting and
   2268 ending blocks in a block group.
   2269 
   2270 Create the generated files read-only to remind developers not to edit them.
   2271 
   2272 Add support for autoconf 2.60 (with backwards compatibility for older
   2273 versions of autoconf).
   2274 
   2275 Added an "make rpm" target to top-level Makefile
   2276 
   2277 Added various FreeBSD portability fixes.
   2278 
   2279 Exclude mercurial files from the RPM build tree to speed up copy/build.
   2280 
   2281 Use root_sysconfdir to define the locations of mke2fs.conf and
   2282 e2fsck.conf instead of using a hard-coded /etc pathname.
   2283 
   2284 Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
   2285 
   2286 Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
   2287 
   2288 If diff -u is supported, use it to report test failures.
   2289 
   2290 Updates/improvements to RPM spec file
   2291 
   2292 Add on-disk format definitions for the following new features:
   2293 EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
   2294 EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
   2295 EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
   2296 
   2297 Add a new make target "checked-failed" in the tests directory which
   2298 reruns any failed tests
   2299 
   2300 Update draft-leach-uuids-guids-01.txt with rfc4122.txt
   2301 
   2302 Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
   2303 pointer dereferences, memory leaks, etc.  None were security-criticial
   2304 problems.
   2305 
   2306 Fix up usage and decrement error messages in the test_icount program
   2307 
   2308 Add debugging code to the com_err library; if the environment variable
   2309 COMERR_DEBUG is set to 1, print out debugging messages as error tables
   2310 are added and removed from the com_err library.  If the
   2311 COMERR_DEBUG_FILE environment variable is set (and the process is not
   2312 setuid) the debugging messages may be redirected to a file.
   2313 
   2314 Change all of the e2fsprogs programs to use the newer add_error_table()
   2315 and remove_error_table() interfaces instead of the much older
   2316 initialize_*_error_table() function.
   2317 
   2318 Add TDB support into the ext2fs library.  This allows us to have a
   2319 guaranteed library we can count on always being present so we can
   2320 store data in an on-disk database.
   2321 
   2322 Add support for using TDB to store the icount data, so we don't run out
   2323 of memory when checking really large filesystems.
   2324 
   2325 Change the regression test suite so that it skips empty test directories.
   2326 
   2327 Define the l_i_iversion field in ext2_inode.  The l_i_version field is
   2328 now defined from the old l_i_reserved1 field in the ext2 inode.  This
   2329 field will be used to store high 32 bits of the 64-bit inode version
   2330 number.
   2331 
   2332 Add Makefile production rule for e2fsprogs.spec in case it gets
   2333 deleted.
   2334 
   2335 Add new function profile_get_uint() to allow for a clean way to fetch
   2336 unsigned integers from the context.
   2337 
   2338 Add test to make sure the ext2 superblock structure is 1024 bytes.
   2339 
   2340 Fix typo in name of f_dup4 regression test
   2341 
   2342 Add new function blkid_gc_cache() which performs a garbage collection
   2343 pass on the /etc/blkid.tab file.
   2344 
   2345 The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY.  In
   2346 general, only e2fsck (after the filesystem is clean), tune2fs, and
   2347 resize2fs should change the backup superblocks by default.  Most
   2348 callers of ext2fs_open() should not be touching any superblock fields
   2349 which require the backups to be touched.
   2350 
   2351 Add new function to libext2fs, ext2fs_default_journal_size(), which
   2352 returns the default journal size.
   2353 
   2354 
   2355 E2fsprogs 1.39 (May 29, 2006) 
   2356 =============================
   2357 
   2358 Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
   2359 between 2**31 and 2**32 blocks.
   2360 
   2361 Change mke2fs to use /etc/mke2fs.conf as a configuration file to
   2362 configure the filesystem features, blocksize, and inode_ratio for
   2363 different filesystem types.
   2364 
   2365 Mke2fs will now create filesystems hash trees and on-line resizing
   2366 enabled by default, based on the new /etc/mke2fs.conf file.
   2367 
   2368 The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
   2369 filesystem device node in exclusive mode to prevent accidents by
   2370 system administrators.  In the case of resize2fs and mke2fs, it will
   2371 only use exclusive mode if the filesystem is not mounted.
   2372 
   2373 Fixed a bug in mke2fs which caused it to to fail when creating the
   2374 resize inode for large filesystems.  (Addresses Debian Bug #346580)
   2375 
   2376 When allocating space for the RAID filesystems with the stride
   2377 parameter, mke2fs will now place each portion of the group's inode
   2378 table right up after the superblock (if present) in order to minimize
   2379 fragmentation of the freespace.
   2380 
   2381 Speed up mke2fs and e2fsck by writing inode and block bitmaps more
   2382 efficiently by writing the inode and block bitmaps in one pass, thus
   2383 reducing the number of disk seeks required.
   2384 
   2385 Add support for on-line resizing to resize2fs.
   2386 
   2387 Fix blkid library so that logic to determine whether or not a device's
   2388 cached information in /etc/blkid.tab needs to be verified or not
   2389 doesn't get confused by a system clock which is insane (for example,
   2390 if the battery is dead on a Macintosh running PPC Linux.  (Addresses
   2391 Red Hat Bug: #182188)
   2392 
   2393 The blkid library will now store the UUID of the external journal used
   2394 by ext3 filesystems, so that in the future, the userspace mount binary
   2395 can use this to find the location of the external journal and pass
   2396 this information to the kernel.
   2397 
   2398 E2fsck will now consult a configuration file, /etc/e2fsck.conf to
   2399 control how various options should be handled.  See the e2fsck.conf
   2400 man page for more details.   (Addresses Debian Bug: #150295)
   2401 
   2402 E2fsck now prints an explanatory message when delaying a filesystem
   2403 check when the system is running on battery.  (Addresses Debian Bug:
   2404 #350306)
   2405 
   2406 E2fsck will detect if the superblock's last mount field or last write
   2407 field is in the future, and offer to fix if so.  (Addresses Debian Bug
   2408 #327580) These problems will be fixed automatically in preen mode
   2409 since Debian's boot sequence bogusly doesn't set the time correctly
   2410 until potentially very late in the bootup process, and this can cause
   2411 false positives which will cause users' systems to fail to boot.
   2412 (Addresses Debian Bugs #343662 and #343645)
   2413 
   2414 E2fsck now checks to see if the superblock hint for the location of
   2415 the external journal is incorrect, and if so, offer to update it.
   2416 (Addresses Debian Bug: #355644)
   2417 
   2418 Fix e2fsck from segfaulting on disconnected inodes that contain one or
   2419 more extended attributes.  (Addresses Debian Bug: #316736, #318463)
   2420 
   2421 E2fsck will stop and print a warning if the user tries running a
   2422 read/write badblocks test on a read-only mounted root filesystem.
   2423 
   2424 Fix a memory leak in e2fsck's error paths.  (Thanks to Michael
   2425 C. Thompson for pointing these out; they were originally found using
   2426 Coverity.)
   2427 
   2428 When resizing a file containing a filesystem, resize2fs will expand or
   2429 truncate a file as necessary.  (Addresses Debian Bug: #271607)
   2430 
   2431 Resize2fs will now automatically determine the RAID stride parameter that
   2432 had been used to create the filesystem, and use that for newly created
   2433 block groups.   The RAID stride parameter may also be manually specified
   2434 on the command line using the new -S option to resize2fs.
   2435 
   2436 Fix mke2fs so that it correctly creates external journals on
   2437 big-endian machines (such as a S/390).  
   2438 
   2439 Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
   2440 fail to print out the journal or hash seed UUID.  (Thanks to Guillaume
   2441 Chambraud for pointing this out.)
   2442 
   2443 Dumpe2fs will now print the size of the journal (if present).
   2444 
   2445 Fix debugfs's set_inode_field command so it can properly set the frag,
   2446 fsize, uid_high, gid_high, and author fields in the inode instead of
   2447 silently failing, and so that setting the i_size actually sets i_size
   2448 correctly.
   2449 
   2450 Add a new debugfs command, set_current_time, which sets fs->now so
   2451 that regression test suites can repeatedly modify the filesystem's
   2452 last_write fields.
   2453 
   2454 Fix a bug in debugfs's icheck which would incorrectly report the owner
   2455 of an extended attribute block.
   2456 
   2457 Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
   2458 print a usage message when an illegal option character is given.
   2459 
   2460 Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
   2461 so it won't core dump.  (Addresses SourceForge bug #1424311)
   2462 
   2463 Fix mklost+found so that it creates a full-sized directory on
   2464 filesystems with larger block sizes.
   2465 
   2466 Fix a file descriptor leak in blkid library.
   2467 
   2468 Fix a display bug in "badblocks -sv" so that the done message properly
   2469 clears the block number at the end of the test.  (Addresses Debian Bug
   2470 #322231)
   2471 
   2472 Allow fractional percentages to the -m option in mke2fs and tune2fs
   2473 (Addresses Debian Bug: #80205)
   2474 
   2475 Use fstat/fstat64 in getsize.c if the the target is a regular file,
   2476 instead of attempting to do a binary search.  Fix some fd leaks in
   2477 error cases.
   2478 
   2479 Add support for device mapper library to the blkid library to ensure
   2480 that the "best" (i.e., leaf) device is probed by the blkid library.
   2481 
   2482 Fix the blkid library so that it notices when an ext2 filesystem is
   2483 upgraded to ext3.
   2484 
   2485 Improve the blkid's library VFAT/FAT detection; it now understands
   2486 labels stored in the root directory, and is more paranoid about
   2487 checking the FAT superblock values.
   2488 
   2489 Fixed a fd leak in the uuid library which was causing problems for the
   2490 LVM tools.  (Addresses Debian Bug: #345832)
   2491 
   2492 Add support for the reiser4 and software suspend partitions to the
   2493 blkid library.  Also add support for extract the label from iso9660
   2494 filesystems.
   2495 
   2496 Fix a compile_et bug which miscount the number of error messages if
   2497 continuations are used in the .et file.
   2498 
   2499 Add extra sanity checks to protect users from unusual cirucmstances
   2500 where /etc/mtab may not be sane, by checking to see if the device is
   2501 reported busy (works on Linux 2.6) kernels.  (Addresses Debian Bug
   2502 #319002)
   2503 
   2504 Updated French, Dutch, Polish, and Swedish translations.  (Addresses Debian
   2505 Bug: #343149, #341911, #300871, #316604, #316782, #330789)
   2506 
   2507 Fix use-after-free bug in e2fsck when finishing up the use of the
   2508 e2fsck context structure.
   2509 
   2510 Fixed spelling mistakes, typos, and otherwise clarified man pages and
   2511 documentation.  (Addresses Debian Bugs: #329859, #322188, #316811,

   2513 #368179)
   2514 
   2515 Fixed various Debian packaging issues --- see debian/changelog for
   2516 details.  (Addresses Debian Bugs #317862, #320389, #290429, #310950,

   2521 Programmer's notes:
   2522 -------------------
   2523 
   2524 Update config.guess and config.sub to latest version (2006-02-23) from
   2525 FSF.
   2526 
   2527 Fix asm_types.h type conflicts on AMD 64 platforms.  (Addresses Debian
   2528 Bugs: #360661, #360317)
   2529 
   2530 Fixed the Makefile so that they work correctly on newer versions of
   2531 GNU make (i.e., 3.81).
   2532 
   2533 Add valgrind support to the regression test suites, and eliminate
   2534 false positives from valgrind.
   2535 
   2536 Add a regression test suite for the blkid library.
   2537 
   2538 Fix a fencepost error in resize2fs caught by valgrind.  
   2539 
   2540 Fix compiler warnings about missing memcpy prototypes.
   2541 
   2542 We no longer have the sparc assembly code in the header file any more,
   2543 so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc.  This would
   2544 break compiles on the sparc architectures when using gcc.
   2545 
   2546 In the libext2fs library, add the new field fs->now which if non-zero
   2547 is used instead of the system time when setting various filesystem
   2548 fields (last modified time, last write time, etc.)
   2549 
   2550 Fix gcc 4.01 complaints by adding a missing #include <string.h> to
   2551 ext2fs.h which is needed since the inline functions use memcpy().
   2552 (Addresses Sourceforge Bug #1251062)
   2553 
   2554 Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
   2555 the build system when building files in the util directory which are
   2556 needed during the build process.  This avoids potential problems when
   2557 cross-compiling and some of the options specified in CFLAGS or LDFLAGS
   2558 are not recognized as valid by the host compiler.  (Addresses
   2559 Sourceforge Bug #1261547)
   2560 
   2561 Clean up the blkid library by making the superblock and generic i/o
   2562 functions to be more generic.  Clean up interface to the probe
   2563 function, and fix memory leak.  Finallly, remove an unneeded reference
   2564 to probe.h in the lib/blkid/resolve.c
   2565 
   2566 Add an ext2fs_read_bb_FILE regression test to confirm proper detection
   2567 of invalid block #'s.
   2568 
   2569 The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
   2570 indicate that the the function read/writes the memory location.
   2571 
   2572 Fix various gcc -Wall complaints.
   2573 
   2574 Add a dependency to make sure that the subdirectories are created
   2575 before creating all of the object files, in order to address parallel
   2576 build problem in the library Makefiles.  (Addresses Sourceforge Bug:
   2577 #1261553)
   2578 
   2579 Add $(LDFLAGS) to the command line argument when generating an ELF or
   2580 Solaris shared library, to allow cross-compile and other builds that
   2581 might need to specify -L paths to needed libraries.  (Addresses
   2582 Sourceforge Bug #1261549)
   2583 
   2584 Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
   2585 intended for testing purposes.  It allows an ext2/ext3 developer to
   2586 create very large filesystems using sparse files where most of the
   2587 block groups are not initialized and so do not require much disk
   2588 space.  Eventually it could be used as a way of speeding up mke2fs and
   2589 e2fsck for large filesystem, but that would be best done by adding an
   2590 RO_COMPAT extension to the filesystem to allow the inode table to be
   2591 lazily initialized on a per-block basis, instead of being entirely
   2592 initialized or entirely unused on a per-blockgroup basis.
   2593 
   2594 Fix backwards compatibility so e2fsprogs will better compile on Linux
   2595 2.0.35 systems.
   2596 
   2597 Make test scripts more robust against locale-related environment variables
   2598 
   2599 Fix type warning problem with sizeof() in ext2fs_open2().
   2600 
   2601 Fix type warning problem with time_t in debugfs.
   2602 
   2603 
   2604 E2fsprogs 1.38 (June 30, 2005)
   2605 ==============================
   2606 
   2607 Fix blkid's test programs (built with "make check") compile correctly
   2608 even without "configure --enable-blkid-debug".
   2609 
   2610 Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
   2611 type aliasing rules on newer gcc compilers.  (Addresses Red Hat
   2612 Bugzilla ##161183.)
   2613 
   2614 Fix com_err library to make it more compatible with recent changes
   2615 made to the com_err library in MIT Kerberos V5 version 1.4.
   2616 (Addresses Sourcefroge Bug #1150146)
   2617 
   2618 General cleanup of messages printed by e2fsprogs programs for grammar,
   2619 consistency, and to make life easier for translators.  Fixed a few
   2620 strings containing English that had not been marked as needing
   2621 translations.  Removed strings that do not need to be translated, to
   2622 make life easier for translators.
   2623 
   2624 Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
   2625 test to see if a device appears to be in use instead of just relying
   2626 on /proc/mounts and /etc/mtab.  (Addresses Debian Bug #308594).
   2627 
   2628 Fix portability problem in the filefrag program affecting platforms
   2629 where the size of an integer is smaller than the size of a long.
   2630 (Addresses Debian Bug #309655)
   2631 
   2632 Mke2fs will now use a larger journal by default for filesystems
   2633 greater than 4GB.  (128 MB instead of 32MB).
   2634 
   2635 Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
   2636 unless forced.  This is to avoid signed vs. unsigned kernel bugs in
   2637 block numbers that still need to be fixed.
   2638 
   2639 The blkid program has a new option which will more efficiently search
   2640 for device when it is known (or expected) that only one matching
   2641 device will be found in the system, such as when doing a lookup by
   2642 UUID.
   2643 
   2644 Debian's e2fsprogs-specific initrd fragment will avoid including
   2645 unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
   2646 and LD_LIBRARY_PATH, and filtering out libraries found in
   2647 /etc/ld.so.preload.  (Addresses Debian Bug: #304003)
   2648 
   2649 Fixed a potential portability issue in the blkid programs for
   2650 architectures where the char type is unsigned.  (Addresses Sourceforge
   2651 Bug: #1180585)
   2652 
   2653 Fix a bug in filefrag so that it doesn't falsely count an extra
   2654 discontinuity when the first block found is an indirect block.
   2655 (Addresses Debian Bug #307607).
   2656 
   2657 Fix blkid's recognition of cramfs filesystems, and enhance it to be
   2658 able to handle cramfs labels.
   2659 
   2660 Fix debugfs's stat command to not core dump when a filesystem is not
   2661 open.
   2662 
   2663 Fix e2fsck's handling of error conditions caused by the resize inode
   2664 claiming blocks that are also used by other inodes, a filesystem
   2665 corruption which was commonly caused by a bug in Fedora Core 3's
   2666 resize2fs program.
   2667 
   2668 Fixed bug in filefrag which caused it to fail on non-ext2/3
   2669 filesystems.  (Addresses Debian Bug: #303509)
   2670 
   2671 If the superblock last mount time indicates that the system clock may
   2672 not be accurate, then e2fsck will omit checking inodes' deletion time
   2673 field for indications of a potential corrupted orphaned inode list.
   2674 (Previously e2fsck only ommited these LOW_DTIME checks when the
   2675 superblock's last write time looked insane.)
   2676 
   2677 Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
   2678 (Addresses Debian bug #302200)
   2679 
   2680 Make the blkid library more paranoid about being run from setgid
   2681 programs, and to use __secure_getenv() from libc if it is available.
   2682 
   2683 Fixed spelling mistakes, typos, and otherwise clarified man pages.
   2684 (Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
   2685 and Sourceforge Bug: #1189803)
   2686 
   2687 Updated and fixed translations.
   2688 
   2689 Fixed various Debian packaging issues --- see debian/changelog for
   2690 details.
   2691 
   2692 Programmer's notes:
   2693 -------------------
   2694 
   2695 Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
   2696 changed to take an unsigned int for the bit number.  Negative bit
   2697 numbers were never allowed (and didn't make any sense), so this should
   2698 be a safe change.  This is needed to allow safe use of block numbers
   2699 greater than or equal to 2**31.
   2700 
   2701 The compile_et program will avoid recreating generated foo_err.c and
   2702 foo_err.h files if no changes are necessary.  The compile_et program
   2703 will also atomically replace these files to avoid a potential parallel
   2704 build race problem on SMP systems.  (Addresses Sourceforge Bug:
   2705 #1157933)
   2706 
   2707 Added a new function to the blkid library, blkid_probe_all_new(),
   2708 which only probes newly added disk devices, and change
   2709 blkid_find_dev_with_tag() to use this function so that when a
   2710 requested tag is not found, devices that were previously not checked
   2711 are searched before searching all devices in the system.
   2712 
   2713 Added new functions to the blkid library, blkid_dev_set_search() and
   2714 blkid_dev_has_tag().
   2715 
   2716 E2fsck's problem strings can now use @m and @n as abbrevations for
   2717 "multiply-claimed" and "invalid", respectively.
   2718 
   2719 The e2fsprog.pot file now has an explanation of how the @-expansion
   2720 and %-expansion works, and strings in e2fsck/problem.c which contain @
   2721 characters now have comments in e2fsprogs.pot with the @-expansion to
   2722 make life easier for translators.
   2723 
   2724 Fixed missing return values in the ext2fs library which could cause it
   2725 to return random garbage in certain error conditions.
   2726 
   2727 Allow the current time to be overriden via the E2FSCK_TIME environment
   2728 variable for use in regression tests.
   2729 
   2730 The test scrpit driver program now exits with a non-zero status if
   2731 there any of its test that it ran failed.
   2732 
   2733 Fixed problems with parabuilds on SMP systems.  (Addresses Sourceforge
   2734 Bug: #1157933)
   2735 
   2736 Fixed "make check" so that it compiles correctly even when e2fsprogs'
   2737 header files have not be installed in the system include directories.
   2738 (Addresses Sourceforge Bug: #1180572)
   2739 
   2740 Fixed gcc -Wall nits.
   2741 
   2742 
   2743 E2fsprogs 1.37 (March 21, 2005)
   2744 ===============================
   2745 
   2746 Add support for checking the validity of Extended Attributes stored in
   2747 inodes to e2fsck.
   2748 
   2749 Add support for dumping the contents of large inodes to debugfs,
   2750 including the extended attributes stored in inodes.
   2751 
   2752 Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
   2753 when we create a new inode we make sure that the extra information in
   2754 the inode (any extra fields in a large inode and any ea-in-inode
   2755 information) is initialized correctly.  This can take place when
   2756 mke2fs creates the root and lost+found directory, when e2fsck creates
   2757 a new root inode or a new lost+found directory, and when the user uses
   2758 the debugfs write, mknod, or mkdir commands.  Otherwise, the newly
   2759 create inode could inherit garbage (or old EA information) from a
   2760 previously deleted inode.
   2761 
   2762 Fixed a bug in e2fsck so it would notice if a file with an extended
   2763 attribute block was exactly 2**32 blocks, such that i_blocks wrapped
   2764 to zero.
   2765 
   2766 Added support to filefrag to detect files which are using the new
   2767 experimental file extents format, and use the non-ext2 algorithm in
   2768 that case.  Fixed a bug to avoid reporting a false discontinuity if
   2769 there is one or more unallocated blocks at the beginning of a file.
   2770 
   2771 Duplicated a check for noticing whether or not the number of blocks
   2772 (given a certain blocksize) is greater than 2**32 when the
   2773 BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size().  This
   2774 allows mke2fs to automatically use a larger blocksize when creating a
   2775 filesystem on a very large device when run on systems that do not
   2776 support BLKGETSIZE64.
   2777 
   2778 Fix the I18N build which was broken in e2fsprogs 1.36 because the
   2779 build system had been switched to treat the .gmo files as shipped
   2780 files (for backwards compatibility with systems that have older GNU
   2781 I18N tools installed), but the gen_tarball.in script was still
   2782 removing the .gmo files from the official source distribution.
   2783 
   2784 Fixed various Debian packaging issues --- see debian/changelog for
   2785 details.  (Addresses Debian Bugs ##296769, #299341)
   2786 
   2787 Programmer's notes:
   2788 -------------------
   2789 
   2790 Added new functions to the e2p library which convert between a string
   2791 and os_type: e2p_os2string() and e2p_string2os(), and used them to
   2792 make the generated binaries more compact.
   2793 
   2794 Fixed a compile-time error on Darwin systems.
   2795 
   2796 Cleaned up the lib/ext2fs Makefile slightly.
   2797 
   2798 
   2799 E2fsprogs 1.36 (February 4, 2005)
   2800 =================================
   2801 
   2802 All of the patches that were applied to Fedore Core 3's
   2803 e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
   2804 lot of bug fixes first.  Users of Fedora Core 3 are strongly
   2805 encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
   2806 
   2807 Add support for filesystem with the online resizing via resize inode
   2808 feature.  Fixed numerous bugs from the Fedora patches.  The Fedora
   2809 patches also didn't bother to do any consistency checking on the
   2810 resize inode, or add any tests to the regression test suite.  The "-R
   2811 resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
   2812 being listed in mke2fs's usage message.  All of these shortcomings
   2813 have been corrected.
   2814 
   2815 E2fsck can also also fix filesystems trashed by Fedora's resize2fs
   2816 program.  In order to do this, the user must run the commands:
   2817 
   2818 	debugfs -w /dev/hdXXX -R "features ^resize_inode"
   2819         e2fsck -f /dev/hdXXX
   2820 
   2821 Optionally, the ext2prepare command can be used to re-enable online
   2822 resizing after the filesystem has been fixed.
   2823 
   2824 The fsck program will now accept an optional filedescriptor argument
   2825 to the -C option.  (The Fedora version of this patch would sometimes
   2826 cause fsck to ignore a parameter on fsck's command line in some rare
   2827 cases, sigh.)
   2828 
   2829 Make sure e2fsprogs doesn't write garbage into the reserved portion of
   2830 large inodes.
   2831 
   2832 Make sure resize2fs releases the blocks belonging to the old inode
   2833 table blocks when moving the inode table.  (Addresses Debian Bug:
   2834 #290894)
   2835 
   2836 Skip the r_resize_inode test if resize2fs is not compiled (due to
   2837 configure --disable-resizer)
   2838 
   2839 E2fsck now checks the summary filesystem accounting information, and
   2840 if any of the information is obviously wrong, it will force a full
   2841 filesystem check.  (Addresses Debian Bug #291571)
   2842 
   2843 Fix e2fsck to not complain when the resize_inode feature is enabled,
   2844 s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
   2845 the resize inode.
   2846 
   2847 Fix e2fsck to note delete symlinks that contain an extended attribute
   2848 after the ext_attr feature flag has been cleared.  (Addresses Red Hat
   2849 Bugzilla #146284).
   2850 
   2851 Add new utility program, copy_sparse.c, which is very useful
   2852 for dealing with large sparse files (such as e2image files).
   2853 
   2854 Add support for jnl_blocks[] for debugfs's set_super_value.
   2855 
   2856 Fix filefrag so that it works correctly with sparse files.
   2857 
   2858 Filefrag -v will print first and last blocks.
   2859 
   2860 Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
   2861 and dumpe2fs.
   2862 
   2863 Add mke2fs support so that it can support filesystems larger than 4TB
   2864 automatically, by retrying with a 4k blocksize if the device size is
   2865 too big to be expressed using a 1k blocksize.  (Addresses Sourceforge
   2866 bug #1106631)
   2867 
   2868 Change blkid to test for NTFS first because Windows sometimes doesn't
   2869 clear enough of the parition to confuse the probing routines into
   2870 thinking the old filesystem type is still valid.  (Addresses Debian
   2871 Bug #291990)
   2872 
   2873 Add support for swap partition label and uuid's in the blkid library.
   2874 
   2875 Add support to the blkid library to recognize Oracle ASM volumes.
   2876 
   2877 Make blkid -t display all devices that match the specified criteria,
   2878 not just the first one, and work more consistently when the blkid
   2879 cache file is not available or set to /dev/null.  (Addresses Debian
   2880 Bug #290530 and #292425)
   2881 
   2882 Badblocks will now correctly display block numbers greater than
   2883 999,999,999 in its progress display.
   2884 
   2885 The tune2fs program will not allow the user from setting a ridiculous
   2886 number of reserved blocks which would cause e2fsck to assume the
   2887 superblock was corrupt.  E2fsck's standards for what is a ridiculous
   2888 number of reserved block has also been relaxed to 50% of the blocks in
   2889 the filesystem.
   2890 
   2891 The blkid library will return vfat in preference to msdos, and ext3 in
   2892 preference to ext2 (if the journalling flag is set) so that mount will
   2893 do the right thing.  (Addresses Debian bug #287455)
   2894   
   2895 Mke2fs will now use the -E option for extended options; the old -R
   2896 (raid options) option is still accepted for backwards compatibility.
   2897 Fix a double-free problem in resize2fs.  (Red Hat Bugzilla #132707)
   2898 
   2899 Mke2fs will now accept a size in megabytes, gigabytes, and other units
   2900 (via "32m" or "4g" on the command line) if the user finds this more
   2901 convenient than specifying a block count.
   2902 
   2903 Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
   2904 cache conherency problem.
   2905 
   2906 Debugfs now supports a new command, set_inode_field, which allows a
   2907 user to manually set a specific inode field more conveniently, as well
   2908 as set entries in the indirect block map.
   2909 
   2910 Debugfs's set_super_value command has been enhanced so that the user
   2911 can set most superblock fields, including the date/time fields and
   2912 some of the more newsly added superblock fields.
   2913 
   2914 E2fsprogs programs now accept an offset to be passed to the file
   2915 specifiers, via the syntax: "/tmp/test.img?offset=1024".
   2916 
   2917 E2fsprogs programs will now accept blocksizes up to 65536; kernel
   2918 support on the x86 doesn't exist for now, but it can be useful on
   2919 other architectures with page sizes greater than 4k.  There are 2.6
   2920 kernel patches out there which enable this, but they are of this
   2921 writing still experimental.
   2922 
   2923 The e2image command now takes the -s option which will scramble
   2924 directory entries for raw image files.
   2925 
   2926 Fix a file descriptor leak in the filefrag program.
   2927 
   2928 Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
   2929 present.
   2930 
   2931 Fix bug in debugfs where kill_file would lead to errors when deleting
   2932 devices and symlinks.  (Sourceforge Bugs #954741 and #957244)
   2933 
   2934 Fix bug in the blkid library when detecting the ocfs1 filesystem 
   2935 
   2936 Remove obsolete EVMS 1.x and a.out DLL support.
   2937 
   2938 E2fsck will attempt to recover from a journal containing illegal blocks.
   2939 
   2940 Fixed two potential ordering constraint problems in e2fsck which might
   2941 cause the filesystem to be corrupted if e2fsck is interrupted during a
   2942 (extremely narrow) race window.  Thanks to Junfeng Yang from the
   2943 Stanford Metacompilation group for pointing this out.
   2944 
   2945 Fixed bug in e2fsck where it would not accurately detect whether or
   2946 not the system is running on adaptor if the ACPI device representing
   2947 the AC adapter didn't correspond to the what was used on IBM
   2948 Thinkpads.
   2949 
   2950 Change e2fsck to accept directories greater than 32MB.
   2951 
   2952 Fix e2fsck so that a checkinterval of zero disables a time-based check
   2953 of the filesystem.
   2954 
   2955 Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
   2956 to the PAGER environment variable.  (Addresses Debian Bug #239547)
   2957 
   2958 Tune2fs will not mark rewrite the superblock if the feature bitmasks 
   2959 are not modified.
   2960 
   2961 The debugfs program will set the filetype information when creating a
   2962 link.
   2963 
   2964 Add debugfs -d option to use a separate source of data blocks when
   2965 reading from an e2image file.
   2966 
   2967 Add e2image -I option which allows the e2image metadata to be
   2968 installed into a filesystem.
   2969 
   2970 Fixed bug in the badblocks program which caused "done" to always
   2971 appear in english even when a translation was available.  (Addresses
   2972 Debian Bug #252836)
   2973 
   2974 The blkid program has a new option -o which controls the output format
   2975 of the blkid program; this is makes blkid more convenient to use in
   2976 shell scripts.
   2977 
   2978 Fix a minor bug in uuid library, which was not using the full 14 bits
   2979 of clock sequence when generating UUID's.
   2980 
   2981 Fix a Y8.8888K problem in the uuid library.
   2982 
   2983 Logsave now creates a new session id for itself to avoid getting
   2984 killed by init whan transitioning between init levels.
   2985 
   2986 Change the licensing of the UUID library to be the 3-clause BSD-style
   2987 license; this allows Apple to use the uuid library in Darwin.
   2988 
   2989 Add ocfs and ocfs2 probe support into the blkid library.
   2990 
   2991 Fix a memory and file descriptor leak in the blkid library.
   2992 
   2993 The blkid library will revalidate the device if the system time is
   2994 earlier than last verification time of the device, since that
   2995 indicates that the system time is probably nottrustworthy.
   2996 
   2997 The blkid library will override the default location of the blkid.tab
   2998 file by the BLKID_FILE environment variable, if it is available.
   2999 
   3000 Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
   3001 
   3002 Add various portability fixes for lame new versions of glibc, Darwin
   3003 and GNU/KFreeBSD, as well as removing XSI:ism's.  (Addresses Debian
   3004 Bugs #239934, #264630, #269044, #255589, #289133)
   3005 
   3006 Add support for Windows 9x/NT under Cygwin.
   3007 
   3008 Updated and clarified various man pages.  (Addresses Debian Bugs #236383,
   3009 	#241940, #238741, #242995, #256669, #268148, #256760, #273679)
   3010 
   3011 Updated and fixed translations.   (Addresses Debian bugs #244105, #262836)
   3012 
   3013 Update the rpm spec files so that it works better with Fedora core 2
   3014 and RH9.
   3015 
   3016 Fixed various Debian packaging issues (see debian/changelog).  In
   3017 particular, fixed the Debian initrd scripts.  (#241183, #248050,
   3018 #253595, #247775)
   3019 
   3020 
   3021 Programmer's notes: 
   3022 -------------------
   3023 
   3024 Fixed various gcc -Wall warnings.
   3025 
   3026 The uuid library now has new functions uuid_unparse_upper() and
   3027 uuid_unparse_lower() which forces the case of the hex digits to be
   3028 upper case, or lower case.
   3029 
   3030 The build process has been speeded up by enhancing the subst program
   3031 to update the modtime on the generated files even when the generated
   3032 file hasn't changed.
   3033 
   3034 The uuid library now uses C99 stdint.h types instead of custom types.
   3035 
   3036 Updated config.guess and config.sub with newer versions from the FSF.
   3037 
   3038 Removed out of date .cvsignore files from the source distribution.
   3039 
   3040 The ext2fs_unlink() function will return an error if both the name and
   3041 inode number are unspecified, to avoid doing something surprising
   3042 (such as unconditionally deleting the first directory entry).
   3043 Directory entries are now deleted by coalescing them with the previous
   3044 directory entry if possible, to avoid directory fragmentation.  This
   3045 is not an issue with the e2fsprogs suite, but may be a problem for
   3046 some of the users of libext2fs, such as e2tools.
   3047 
   3048 Add support for version numbers of the form "1.36-rc1".
   3049 
   3050 Fix build of mke2fs.static.
   3051 
   3052 Add basic ext2fs library support for large (EA in inode) inodes.
   3053 
   3054 The test_io mechanism can now abort after n reads or writes to a
   3055 particular block.  The block is specified by TEST_IO_BLOCK environment
   3056 variable, and the read/write count by the TEST_IO_READ_ABORT and
   3057 TEST_IO_WRITE_ABORT environment variables.  The block data is now only
   3058 dumped if the 0x10 bit is set in TEST_IO_FLAGS.
   3059 
   3060 UUID_DEFINE() in the uuid library now creates a static variable, with
   3061 __attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
   3062 be used in header files.
   3063 
   3064 Add support for the install-strip and install-shlibs-strip targets, as
   3065 suggested by the GNU coding guielines.  "make install" no longer
   3066 strips the binaries which are installed.
   3067 
   3068 Remove support for the --enable-old-bitops configure option which was
   3069 only for very old sparc systems.
   3070 
   3071 Remove support for --enable-clear-htree; this was only needed during
   3072 the early development of the htree patch.
   3073 
   3074 Use Linux-kernel-style makefile output so it is easier to see compiler
   3075 warnings.
   3076 
   3077 Update gettext files to version 0.14.1.
   3078 
   3079 Update to use autoconf 2.5x.
   3080 
   3081 Improved support for compiling e2fsprogs under dietlibc.
   3082 
   3083 Make e2fsprogs portable to Solaris and FreeBSD systems.
   3084 
   3085 Add blkid_verify(), blkid_get_library_version(), and
   3086 blkid_parse_version_string() functions to the blkid library.
   3087 
   3088 Add pkg-config files for e2fsprogs's libraries.
   3089 
   3090 Fix "make uninstall" to so that it removes everything that is installed.
   3091 
   3092 Add a configure --enable-maintainer-mode option which enables the
   3093 makefile rules to rebuild the configure script from configure.in, and
   3094 to reubuild the .gmo files in po directory.
   3095 
   3096 Drop the sparc assembly bitwise operations; it's less efficient
   3097 than the GCC 3.4 compile code and triggers compiler warnings on
   3098 sparc64.  Thanks to Matthias Andree for his analysis and suggestions.

   3101 
   3102 E2fsprogs 1.35 (February 28, 2004) 
   3103 ==================================
   3104 
   3105 E2fsck has a new -k option, which in conjunction with the -c options,
   3106 preserves the existing badblocks list.
   3107 
   3108 Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
   3109 
   3110 E2fsprogs will now deal correctly with symlinks that contain
   3111 extended attribute information, which can be created using SE Linux.
   3112 (Addresses Debian Bug #232328)
   3113                                                                                
   3114 Remove a double longjump into an invalid stack frame bug in e2fsck.
   3115 (This was during an abort sequence, which normally worked on Linux and
   3116 caused a core dump on other operating systems.)
   3117 
   3118 Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
   3119 (the NLS library will replace "" with the .po header information).
   3120  
   3121 Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
   3122 dump due to a division by zero error.  (Addresses Debian bug #207082)
   3123 
   3124 Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
   3125 when reconnecting a directory requires creating a lost+found
   3126 directory.  (Addresses Debian bug #219640).
   3127 
   3128 Fixed a bug where e2fsck would bomb out if a journal needed to be
   3129 replayed when using an alternate superblock.
   3130  
   3131 E2fsck will give an extra grace period before actually forcing a check
   3132 if the laptop is running on battery.  The next time fsck runs while
   3133 the system is on the AC mains, or after the grace period is exceeded,
   3134 the filesystem will be checked.  (Addresses Debian bug #205177)
   3135 
   3136 E2fsck will inform the user when there are 5 or fewer mounts before a
   3137 filesystem check will be forced.  (Addresses Debian bug #157194)
   3138 
   3139 Fix e2fsck's handling of corrupted indirect blocks in the bad block.
   3140 We now correctly handle the case where there is an overlap between a
   3141 block group descriptor or a superblock and a bad block indirect block.
   3142 In the case where the indirect block is corrupted, we now suggest
   3143 "e2fsck -c".
   3144 
   3145 Fix byte swap bugs in e2fsck that caused the journal backup location 
   3146 in the superblock and symlinks created by SE Linux to be cleared
   3147 by e2fsck on big-endian machines.  (Addresses Debian bug #228723)
   3148 
   3149 E2fsck -c now replaces the current list of bad blocks with the ones
   3150 found by badblocks.
   3151 
   3152 Fix bugs in e2fsck and tune2fs which could cause a core dump if a
   3153 non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
   3154 
   3155 Fix a potential bug in e2fsck which could cause it to core dump when
   3156 trying to print the location of the backup superblock.
   3157 
   3158 Protect against a potential core dump in e2fsck when printing a
   3159 message about backup superblocks.
   3160 
   3161 Add support for backing up the journal inode location in the
   3162 superblock.  E2fsck will automatically save the journal information in
   3163 the superblock if it is not there already, and will use it if the
   3164 journal inode appears to be corrupted.  ext2fs_add_journal_inode()
   3165 will also save the backup information, so that new filesystems created
   3166 by mke2fs and filesystems that have journals added via tune2fs will
   3167 also have journal location written to the superblock as well.
   3168 Debugfs's logdump command has been enhanced so that it can use the
   3169 journal information in the superblock.
   3170 
   3171 E2fsck will now update all superblocks when moving the journal inode.
   3172   
   3173 Shrink the size of the e2fsck executable by moving some initialized
   3174 variables to the BSS segment.
   3175 
   3176 E2fsck will avoid printing the ^A and ^B characters which bracket the
   3177 progress bar when stdout and stdin are a tty device instead of a pipe
   3178 to another program.  (Addresses Debian bug #204137)
   3179 
   3180 Debugfs's mkdir command will automatically expand the directory if
   3181 necessary.  (Addresses Debian Bug: #217892)
   3182  
   3183 Fixed a bug in debugfs so that copying a file from /dev/null uses the
   3184 correct mode bits.  (Addresses Debian Bug: #217456)
   3185  
   3186 If the environment variables DEBUFS_PAGER and PAGER are not set,
   3187 debugfs now searches for the appropriate pager to use, beginning with
   3188 /usr/bin/pager, and then falling back to 'more' and 'less'.
   3189 (Addresses Debian bug #221977)
   3190 
   3191 Debugfs will now support 2.6 device numbers where the major or minor
   3192 number may be larger than 255.  (Addresses Sourceforge bug #865289)
   3193  
   3194 Fix debugging printf in resize2fs.  (Addresses Debian Bug #271605)
   3195 
   3196 Chattr now stops processing options when it sees '--'.  (Addresses
   3197 Debian bug #225188)
   3198 
   3199 Fix regression tests so they work correctly when e2fsprogs is compiled
   3200 with configure --disable-htree.
   3201 
   3202 Fix bug in uuid library when there is no network card and the library
   3203 is generating a time-based uuid.  The random MAC address was not
   3204 correctly generated to be a multicast address.
   3205  
   3206 Add compile_et extensions from Heimdall that were missed the first time
   3207 around.
   3208 
   3209 Fix bug in badblocks when using O_DIRECT; we need to make sure that
   3210 we're reading from an offset which is page aligned.  For read-only and
   3211 read-write tests, we try to recover after an error so that we can
   3212 continue reading on page-aligned boundaries.  (Addresses Debian Bug
   3213 #203713)
   3214   
   3215 Badblocks now checks 64 blocks at a time instead of 16.  (Addresses
   3216 Debian bug #232240)
   3217  
   3218 Updated and clarified various man pages.  (Addresses Debian Bug
   3219 #206845, #222606, #214920, #232406)
   3220 
   3221 Updated and fixed translations.   (Addresses Debian bugs #200086, #214633)
   3222 
   3223 Fixed various Debian packaging issues (see debian/changelog).
   3224 
   3225 Programmer's notes: 
   3226 -------------------
   3227 
   3228 Fixed a build problem so that e2fsprogs would compile with the
   3229 --enable-profile option to configure selected.  (Addresses Sourceforge
   3230 bug #811408)
   3231  
   3232 Fixed C++ problems with the ext2fs.h header.  (Addresses Red Hat
   3233 Bugzilla Bug #112448)
   3234                                                                                
   3235 Centralize code which calculates the location of the superblock
   3236 and block group descriptors so that it is in a single library routine.
   3237 
   3238 Added two new functions, ext2fs_file_open2() and
   3239 ext2fs_inode_io_intern2() which take a pointer to an inode structure.
   3240 
   3241 Fix compile_et to output the correct prototype for
   3242 initialize_xxx_err_table_r() in the header file.  (Addresses Debian
   3243 bug #204332)
   3244 
   3245 In the lib/et makefile, make sure com_err.info is deleted on "make clean".
   3246   
   3247 Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
   3248 present.  This is for when we try stuffing an int into void * pointer.
   3249 
   3250 Fix type-punning which can cause gcc 3.x to miscompile code by getting
   3251 confused about pointer aliasing.  ext2fs_getmem(), ext2fs_free_mem(),
   3252 and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
   3253 **'.  The EVMS code uses an ugly union approach since we don't want to
   3254 modify the EVMS interfaces. 
   3255 
   3256 Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
   3257 aid build process on systems can use invoke GNU make as "gmake".
   3258 
   3259 Added regression testing for mke2fs.
   3260 
   3261 Fixed gcc -Wall nitpicks.
   3262 
   3263 Fixed various compiler warnings.
   3264 
   3265 Add portability fixes for FreeBSD and for using fsctl under Darwin to
   3266 support ext2 ioctl's.
   3267 
   3268 
   3269 E2fsprogs 1.34 (July 25, 2003)
   3270 ===============================
   3271 
   3272 Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
   3273 a tight loop while waiting for a child fsck to exit in some cases.
   3274 This burns CPU times which slows down the low-level filesystem check.
   3275 
   3276 Added code to mke2fs to assure that the default block size for a
   3277 filesystem is at least as big as the sector size of the device, if it
   3278 can be determined.
   3279 
   3280 Changed mke2fs and resize2fs to round the default size of a filesystem
   3281 to be an even multiple of the VM pagesize in order to avoid a Linux
   3282 kernel bug introduced when the storage of the buffer cache was moved
   3283 into the page cache.
   3284 
   3285 Mke2fs will warn the user when creating a filesystem with journaling
   3286 and a blocksize greater than 4096.  (Addresses Debian bug #193773)
   3287 
   3288 Fixed a bug in resize2fs which caused it to fail on filesystems with a
   3289 non-empty bad block list.  Resize2fs now discards any blocks on the
   3290 badblock list which are no longer part of the filesystem as the result
   3291 of a filesystem shrink.  (Note: this means that shrinking and then
   3292 enlarging a filesystem is no longer a reversible operation;
   3293 information about bad blocks in the part of the filesystem which is to
   3294 be chopped off will be lost.)
   3295 
   3296 Changed resize2fs so the user can use prefixes to specify the units of
   3297 the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
   3298 and to make the error and informational messages explicitly display
   3299 the blocksize used by the filesystem, in order to avoid confusion.
   3300 (Addresses Debian bug: #189814)
   3301 
   3302 Added a new debugfs command, dump_unused, which dumps the contents of
   3303 all unused blocks to stdout.  (Useful as an emergency try-to-find
   3304 deleted data command.)
   3305 
   3306 Added a new debugfs command, imap, which prints the location of a
   3307 specified inode in the inode table.
   3308 
   3309 Fixed a bug in the badblocks program which caused it to use one bit of
   3310 randomness in its non-destructive read/write test, instead of using a
   3311 full 8 bits of randomness.
   3312 
   3313 Added a new option (-t) to badblocks, which allows the user to control
   3314 the test pattern(s) used when checking a disk.
   3315 
   3316 The blkid probe function now more correctly detects UDF filesystems.
   3317 
   3318 Fixed a bug in the blkid library which caused it to not update its
   3319 cache if a filesystem changes from having a label to not having a
   3320 label.
   3321 
   3322 Fixed a bug in the blkid library wihch could avoid an infinite loop
   3323 in blkid_find_dev_with_tag() if /proc is not mounted and there the
   3324 /etc/blkid.tab file has not yet been created.
   3325 
   3326 Fixed the badblocks program so that the destructive read/write test
   3327 honors the -c option, and to use O_DIRECT when possible to avoid
   3328 thrashing the system block buffer cache.
   3329 
   3330 Fixed various NLS issues.
   3331  - Added Czech and Swedish translations
   3332  - Removed testing NYC translation
   3333  - Fixed NLS support for message abbrevations in e2fsck
   3334  - Remove de-utf.po, since we shouldn't have two versions using different
   3335 	charset encodings.
   3336  - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to 
   3337 	simplify the statistics reporting in e2fsck.
   3338 
   3339 Changed configure.in so that its defaults for *BSD systems no longer
   3340 build an fsck wrapper, and not to install in /usr/local by default.
   3341 
   3342 Fixed some minor spelling errors/typo's in e2fsck and the configure
   3343 script.
   3344 
   3345 Fixed various Debian packaging issues (see debian/changelog). 
   3346 
   3347 Updated and clarified man pages.  (Addresses Debian Bug #195616)
   3348 
   3349 Programmer's notes: 
   3350 -------------------
   3351 
   3352 Fix gcc -Wall nitpicks.
   3353 
   3354 Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
   3355 NLS support by default.  (Added partial workaround for gettext/Darwin
   3356 incompatibility problems.)
   3357 
   3358 Added full MIT KRB5 and Himdall compaibility support to the com_err
   3359 library and the compile_et program.  (Addresses Debian bug #191900)
   3360 
   3361 Added the blkid_known_fstype() function to the blkid library, which
   3362 returns true if it is passed a filesystem type which is recognized by
   3363 the blkid probing functions.
   3364 
   3365 Improved the documentation for the blkid library.
   3366 
   3367 Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
   3368 returns the hardware sector size of a device, if it is available.
   3369 
   3370 Added a dependency in the blkid library's .so file to the uuid
   3371 library, since the former uses the latter.  (Addresses Debian bug
   3372 #194094)
   3373 
   3374 Added --with-diet-libc and --disable-evms to the configure script.
   3375 
   3376 Fixed a minor memory leak in the badblocks program.
   3377 
   3378 Fixed a portability problem in tune2fs --- not all systems have strptime().
   3379 
   3380 Fixed a portability problem in debugfs with the use of getopt() more
   3381 than once.  Old-style BSD, new-style BSD, and Linux C libraries all do
   3382 things differently.
   3383 
   3384 Add support Windows support to ext2fs_get_device_size().
   3385 
   3386 Added (normally disabled) debugging code to the Unix I/O manager which
   3387 causes it to disable all userspace caching if the NO_IO_CACHE is
   3388 defined.
   3389 
   3390 Changed the test I/O manager so it can always be linked into e2fsck,
   3391 mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
   3392 configure script.  The test I/O manager will only print any debugging
   3393 information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
   3394 variables are set, which specifies which I/O operations are logged and
   3395 a block number to watch, respectively.  The log messages are sent to
   3396 stderr by default, unless a filename is specified via the
   3397 TEST_IO_LOGFILE environment variable.
   3398 
   3399 
   3400 E2fsprogs 1.33 (April 21, 2003)
   3401 ===============================
   3402 
   3403 Added a new utility program, logsave, which captures the output of a
   3404 command in a log file, even if the containing directory hasn't been
   3405 mounted yet (in which case the it saves the output in memory until it
   3406 can write out the logfile).  This is useful for capturing the
   3407 output of fsck during the boot sequence.
   3408 
   3409 Fixed some portability problems that were causing problems under
   3410 the Cygwin32 environment.
   3411 
   3412 Mke2fs now interprets a negative number to the -b option as a minimum
   3413 block size.
   3414 
   3415 Fixed a bug in mke2fs which was incorrectly checking the argument to
   3416 the -g option if the default block size was used.  (Addresses Debian
   3417 bug #188319)
   3418 
   3419 Fsck now explicitly ignores tmpfs and devpts, and it will complain if
   3420 it can not find filesystem checkers for jfs, reseirfs, and xfs.
   3421 
   3422 E2fsck now updates the global free block and inode counters from the
   3423 block group specific counters quietly.  This is needed for an
   3424 experimental patch which eliminates locking the entire filesystem when
   3425 allocating blocks or inodes; if the filesystem is not unmounted
   3426 cleanly, the global counts may not be accurate.
   3427 
   3428 Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree.  (EVMS
   3429 2.0 is not yet supported; this only pulled in the bug fixes: fixed
   3430 possible hangs caused by bugs in calling waitpid, and not setting the
   3431 pipe to non-blocking mode; also fixed a file descriptor leak; made
   3432 sure all functions call log entry/exit functions.)
   3433 
   3434 Badblocks now flushes its output file as bad blocks are discovered.
   3435 
   3436 The uuid library is now more paranoid about assuming the correctness
   3437 of the /dev/random device; it mixes in a stream of bytes from
   3438 random/srandom, just in case.
   3439 
   3440 Update Debian files to reflect the fact that I am now the Debian
   3441 maintainer of e2fsprogs.  Other various Debian-specific packaging
   3442 cleanups.
   3443 
   3444 Move the source tarball generation functions from the top-level
   3445 makefile to the util/gen-tarball script.  
   3446 
   3447 Updated the Turkish .po translation file.
   3448 
   3449 Added Heimdal and MIT krb5 extensions to the com_err library to make
   3450 it more compatible with com_err libraries from those distributions.
   3451 
   3452 Changed dumpe2fs to always display the superblock fields relating to
   3453 the journalling and/or directory indexing feature even if those
   3454 features are not enabled.
   3455 
   3456 Updated and clarify copyright statement vis-a-vis alpha releases of
   3457 e2fsprogs.
   3458 
   3459 The ss library will now try to dynamically link to the readline
   3460 library and use it if it is present in the system.  This means that
   3461 the debugfs program now has line editing and history features.  The
   3462 SS_READLINE_PATH environment variable is used to find a readline or
   3463 readline-compatible library.
   3464 
   3465 E2fsck now finds most duplicate filenames (all when rebuilding all
   3466 directories via the -D option) and offers to delete or rename
   3467 duplicate filenames/directory entries.  (Addresses Debian Bug #176814).
   3468 
   3469 Fix bug in e2image.  When writing out a raw image file, include data
   3470 blocks from symlinks that do not store the symlink within the inode.
   3471 
   3472 Fix bug in resize2fs which incorrectly moved the block and inode
   3473 bitmaps for sparse superblock filesystems and incorrectly marked
   3474 blocks as in use.  (Addresses Debian bug #174766)
   3475  
   3476 Added a new shared library, the blkid library, which efficiently
   3477 allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
   3478 and UUID filesystem specifiers without needing to search all of the
   3479 devices in the system.  Instead, the device is looked up in a cache
   3480 file, and then verified to make sure the blkid cache is correct.
   3481 
   3482 Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
   3483 the device name, using the blkid library.  (Addresses Debian bugs
   3484 #166048, #179671)
   3485 
   3486 Fsck now supports backslash escapes in /etc/fstab so that \040 can be
   3487 used for spaces in device labels.
   3488 
   3489 Removed 32-bit limitations for debugfs's dump command.
   3490 
   3491 If the user specifies a large number of inodes, Mke2fs will
   3492 automatically adjust the number of blocks per group to find a valid
   3493 set of filesystem parameters.
   3494 
   3495 Add workaround to detect broken MD devices where when some of the
   3496 underlying devices are marked read-only, writes to the MD device are
   3497 silently dropped.  E2fsck will detect if there is an attempt to run
   3498 the journal twice, and abort with an error if this is the case.
   3499 (Addresses IBM Bugzilla bug #1226)
   3500 
   3501 E2fsck will print an error if more than one of the -p/-a, -n or -y
   3502 options are specified.
   3503 
   3504 E2fsck will fix HTREE corruptions in preen mode, without stopping the
   3505 boot process.  This is needed because the 2.4 ext2 filesystem
   3506 accidentally had the INDEX_FL backwards compatibility code removed.
   3507 
   3508 Mke2fs no longer creates filesystems with the dir_index flag set by
   3509 default; the user has to specifically request it.
   3510 
   3511 Update and clarified various man pages. (Addresses Debian bugs
   3512 #173612, #175233, #175113, and #170497, #185945, #188318)
   3513 
   3514 Created man page for the mk_cmds program (from the libss library).
   3515 
   3516 Programmer's notes: 
   3517 -------------------
   3518 
   3519 Fix various gcc -Wall nits.
   3520 
   3521 Fixed a lot of portability problems that caused e2fsprogs not to build
   3522 successfully under Solaris and Apple/Darwin.
   3523 
   3524 Fixed a Makefile dependency to allow building e2fsprogs using parallel
   3525 make jobs.
   3526 
   3527 Changes to create a subset distribution which consists only of the
   3528 et, ss, uuid, and blkid libraries.  The configure script and top-level
   3529 makefile were changed to support working with a subset distribution.
   3530 
   3531 Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
   3532 actually used, and might people who are looking for
   3533 EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
   3534 
   3535 Updated debian files to fix a number of Lintian warnings.
   3536 
   3537 Updated config.guess and config.sub with newer versions from the FSF.
   3538 
   3539 Removed unnecessary libraries from being linked into the fsck, lsattr, 
   3540 chattr, and blkid executables.
   3541 
   3542 E2fsprogs 1.32 (Nomvember 9, 2002)
   3543 ==================================
   3544 
   3545 Fixed a bug in the Unix I/O routines which caused needless writebacks
   3546 of clean blocks from the unix_io cache (they were erroneously marked
   3547 as being dirty, so they were getting written back to disk before
   3548 getting evicted from the disk cache).  This was harmless, but it
   3549 significantly slowed down e2fsck.
   3550 
   3551 Made some other minor optimizations to the Unix I/O routines to save a
   3552 small amount of CPU time.
   3553 
   3554 Updated internationalization files.
   3555 
   3556 
   3557 E2fsprogs 1.31 (Nomvember 8, 2002)
   3558 ==================================
   3559 
   3560 Update EVMS ext2fsim plugin with EVMS 1.2.  (We still support
   3561 compiling the fsim plugin with EVMS 1.0 and 1.1.)  Add better error
   3562 handling for child process that die unexpectly.  Add a hack to force
   3563 mkfs to create filesystems that won't cause problems with hardware
   3564 that has 2k or 4k minimum blocksize requirements.  Read from child
   3565 processes in non-blocking mode, so that the GUI continues to update.
   3566 
   3567 Fix e2fsck so that it returns the appropriate exit code when the root
   3568 filesystem has been changed, so that system's rc scripts will be told that 
   3569 the system needs to be rebooted.
   3570 
   3571 Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
   3572 was set, some of the descriptor blocks that should have been written
   3573 out were getting skipped.
   3574 
   3575 Changed e2fsck to force out changes to the backup copies of the
   3576 superblock and block group descriptors when important changes are made
   3577 to those data structures.
   3578 
   3579 Fix a bug where e2fsck could erroneously mark a filesystem as being
   3580 clean if a check of dirty filesystem is interrupted with a ^C.  (Bug
   3581 introduced in e2fsprogs 1.28.)
   3582 
   3583 If journal debuging is enabled using --enable-jbd-debug, the debugging
   3584 level is now set via the E2FSCK_JBD_DEBUG environment variable.
   3585 
   3586 If byteswapping support is disabled using configure --disable-swapfs,
   3587 skip the tests which depend on byte-swapping, so that "make check"
   3588 won't bomb out.
   3589 
   3590 Lshattr will now display the indexed directory flag.  Also, some of
   3591 the more esoteric compression flags are supressed unless compression
   3592 support has been enabled.
   3593 
   3594 Update man pages.
   3595 
   3596 
   3597 E2fsprogs 1.30 (October 31, 2002)
   3598 =================================
   3599 
   3600 When resizing a filesystem, and inodes need to moved, resize2fs will
   3601 update the inode's ctime field, and the mtime field of the containing
   3602 directories, so that incremental backups using dump/restore will work
   3603 correctly.
   3604 
   3605 In order to avoid spurious errors, e2fsck wil check the last
   3606 superblock write time to determine whether or not it can safely use
   3607 the LOW_DTIME checks to determine if there are inodes on the orphan
   3608 inode linked list that had somehow gotten disconnected.  (Addresses
   3609 Sourceforge bug #620980)
   3610 
   3611 Partition in /proc/partitions that being with the string "lvm" are
   3612 considered real partitions even if they do not end with a number.
   3613 
   3614 Fixed a bug in the the uuid generation function, where if /dev/urandom
   3615 is not present, but /dev/random is, and there isn't sufficient
   3616 entropy, the get_random_byte function could spin a loop forever.
   3617 
   3618 E2fsck, mke2fs, etc. will now reliably notice when image files are
   3619 mounted using the loopback interface.  (Addresses Sourceforge bug
   3620 #619119)
   3621 
   3622 When flushing buffers (as is done by badblocks, for example) check to
   3623 see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
   3624 FDFLUSH ioctl which causes the MD device driver which causes confusing
   3625 syslog messages about obselete ioctl messages.  (Addresses Sourceforge
   3626 bug #545832).
   3627 
   3628 Debugfs's write command now checks to see if the destination filename
   3629 exists before creating it.  (Addresses Sourceforge bug #478195.)
   3630 
   3631 When installing man pages, search for compressed man pages using all
   3632 commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
   3633 
   3634 Fixed a bug in fsck where multiple filesystems specified on the
   3635 command were not being checked in parallel due to a logic bug
   3636 introduced to support the FSCK_MAX_INST environment variable.
   3637 
   3638 We have added a new superblock field, s_mkfs_time, which indicates
   3639 when a filesystem was created.  It is set via mke2fs, and printed out
   3640 by dumpe2fs, but is not actually touched by the kernel.
   3641 
   3642 Dumpe2fs has been made more robust by not aborting if there is an
   3643 error reading the block/inode bitmaps; instead it will still print out
   3644 the location of the block/inode bitmaps and inode table.
   3645 
   3646 Add support for the an alternative block group descriptor layout which
   3647 allows for on-line resizing without needing to prepare the filesystem
   3648 in advance.  (This is the incomat feature flag meta_bg.)
   3649 
   3650 Add support for storing default mount options in the superblock, so
   3651 that the filesystem can be mounted with specific mount options without
   3652 needing to specify them on the mount command line or in the /etc/fstab
   3653 file.
   3654 
   3655 Add support for a new inode flag, which is to be used for indicating
   3656 the top of directory hierarchies for the Orlov block allocator.
   3657 
   3658 Fix e2fsck so that if it creates the lost+found directory, it does so
   3659 with the more apporpriate permissions of 0700.  Also change
   3660 mklost+found so that it also creates the directory 0700.
   3661 
   3662 Fixed format bug in e2fsck if NLS is in use.
   3663   
   3664 Add a German translation for e2fsprogs's NLS support.
   3665 
   3666 Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
   3667 the beginning of the inode table.  This won't matter much, since if
   3668 there is a bad block at the beginning of the inode table, the root
   3669 directory won't be available.  But at least e2fsck won't crash in this
   3670 case.
   3671 
   3672 Fixed endian problems in the htree code for e2fsck and debugfs.
   3673   
   3674 When byte-swapping a filesystem on a PPC architecture, byte-swap the
   3675 bitmaps since the historical big-endian ext2 variant had byte-swapped
   3676 bitmaps, and the ext2fs library assumes this.  This fixes the
   3677 regression test suite on PPC machines.
   3678 
   3679 Fix e2image so that it handles a bad block in the inode table
   3680 appropriately.
   3681 
   3682 E2fsck now uses a more sophisticated algorithm to salvage corrupted
   3683 directories that recovers more information in the corrupted directory
   3684 block.
   3685 
   3686 E2fsck now performs additional consistency checks on indexed (HTREE)
   3687 directories.
   3688 
   3689 Fix bug where efsck might get confused about whether a completely
   3690 empty directory block is an empty leaf block or an interior htree
   3691 node.  This could cause e2fsck to get confused into think that a valid
   3692 indexed directory was corrupted.
   3693 
   3694 E2fsck no longer creates an empty directory entry at the end of a
   3695 directory block when optimizing a directory.  This would cause some
   3696 earlier versions of the dxdir kernel code to corrupt the directory
   3697 when attempting to split a node containing an empty directory entry.
   3698 
   3699 E2fsck could sometimes in rare circumstances leave the indexed flag
   3700 set after a small directory was optimized by compressing it instead of
   3701 indexing it.  (This should never happen in real life, since
   3702 directories that small wouldn't have been indexed, but better safe
   3703 than sorry.)
   3704 
   3705 E2fsck now only updates the master superblock in all cases.  This
   3706 slightly shortens its run time.
   3707 
   3708 Ext2ed can deal with directory entries of length 0; previously it
   3709 would get stuck in an infinite loop.
   3710 
   3711 Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
   3712 specifiers.  (Sourceforge patch #613447)
   3713 
   3714 Badblocks will now work correctly on read-only devices such as
   3715 CD-ROM's.  (Sourceforge patch #600451)
   3716 
   3717 Updated and clarified man pages.  (Addresses Debian bug #167108)
   3718 
   3719 
   3720 E2fsprogs 1.29 (September 24, 2002)
   3721 ===================================
   3722 
   3723 Fixed a bug in e2fsck which could corrupt a directory when optimizing
   3724 it (via the -D option) or rebuiliding the hash tree index with a 1 in
   3725 512 probability, due to a fence post error.
   3726 
   3727 Fixed a bug in the LVM support code which caused LABEL='xxx' not to
   3728 work correctly.
   3729 
   3730 Mke2fs now enables the directory indexing flag by default.  (Since
   3731 this is a compatible feature flag, it's safe to do so.)
   3732 
   3733 Tune2fs will support setting the directory indexing feature flag.  It
   3734 will automatically set up the default hash algorithm and hash seed
   3735 fields in the superblock.
   3736 
   3737 If the bone-headed user enters the root filesystem twice in
   3738 /etc/fstab, the -R option which skips the root filesystem will skip
   3739 all of them.  (Addresses Debian bug #159423).  Note!  This is not a
   3740 precedent for dealing intelligently with any other kind of doubled
   3741 entry in /etc/fstab!
   3742 
   3743 
   3744 Programmer's notes: 
   3745 -------------------
   3746 
   3747 Removed perror declaration in lib/et/internal.h.  All modern systems
   3748 can be expected to define perror() these days.  Besides, the lib/et
   3749 code wasn't using perror at all anyway.  :-)
   3750 
   3751 
   3752 E2fsprogs 1.28 (August 31, 2002)
   3753 ================================
   3754 
   3755 Add support for the Hashed-Tree Directory Indexing to e2fsck.  Support
   3756 for setting the htree flag is not included yet, although it can be
   3757 manually turned on via the debugfs program.
   3758 
   3759 Clarified e2fsck error message which is printed when it cannot find
   3760 sufficient contiguous block when relcating filesystem metadata.
   3761 
   3762 Added support for building an EVMS plugin module for ext2/3.  This
   3763 module is substantially the same as the EVMS module shipping with EVMS
   3764 1.1, with one or two bugfixes.  E2fsprogs can also build this plugin
   3765 for use with EVMS 1.0 (which did not include the ext2 plugin module),
   3766 if the configure --enable-old-evms flag is given.
   3767 
   3768 Fsck will search through EVMS volumes when trying to resolve
   3769 filesystem specifications such as LABEL=xxx or UUID=xxx.
   3770   
   3771 Added a new utility program, /sbin/findfs, which will return
   3772 filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
   3773 the device name.
   3774 
   3775 Update and clarified various man pages. (addresses Debian Bug #145044,
   3776 #146437, #131350, #151990, #144621, #141938)
   3777 
   3778 If there are no filesystems specified on fsck's command line, fsck now
   3779 treat that as if the -As options were given.  Previously it would
   3780 simply do nothing.  (Addresses Debian Bug #153102)
   3781 
   3782 Mke2fs no longer treats a failure to be able to clear the MD signature
   3783 at the end of the filesystem as a fatal error.  (Addresses Debian Bug
   3784 #155007)
   3785 
   3786 The e2p library functions (which are used by lsattr and chattr) now
   3787 double check to make sure the file is a regular file or directory
   3788 before attempting to use the ext2 ioctls.  Some device drivers
   3789 unfortunately respond to the ext2 ioctl's with unknown behaviour.
   3790 (Addresses Debian Bug #152029).
   3791 
   3792 The extended attribute handling has been updated to correspond with
   3793 the latest V2 bestbits ACL code.
   3794 
   3795 Fixed bug in e2fsck which caused it to not clear the dtime field when
   3796 processing truncated inodes on the orphan list.  This could cause data
   3797 loss(!) if a filesystem is rebooted before a truncate has been
   3798 committed.
   3799 
   3800 E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
   3801 algorithms.  This makes e2fsck much faster in the case of severely
   3802 corrupted filesystems where a large number of blocks are claimed by a
   3803 large number of inodes.  (Thanks to the 2.5 IDE device driver for
   3804 inspiring this work.)
   3805 
   3806 Resize2fs has been significantly sped up when shrinking and expanding
   3807 a filesystem by a very small number of blocks (for example, when EVMS
   3808 is converting a partition to be an EVMS legacy volume).
   3809 
   3810 Added a new option to e2fsck, -D, which will optimize or compress all
   3811 of the directories in the filesystem.
   3812 
   3813 E2fsck now catches SIGINT and SIGTERM to make sure it will can
   3814 properly clean up and only exit at safe points.  Fsck will pass
   3815 SIGINT/SIGTERM to its child processes, and wait until they have all
   3816 exited before it exits.
   3817 
   3818 The uuid parsing code in the uuid library now properly complains when
   3819 an illegally formated uuid is presented to it.  (Addresses Debian bug
   3820 #152891)
   3821 
   3822 Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
   3823 and 2.4.17, since the workaround can cause problems when using a 2.4
   3824 kernel with an old version of glibc built with the 2.2 headers.
   3825 
   3826 Fixed a bug in mke2fs where it wasn't properly clearing the initial
   3827 superblock used by other filesystems.  (Addresses Debian bug #147256.)
   3828 
   3829 Added support for the synchronous directory feature written by Andrew
   3830 Morton.
   3831 
   3832 The debugfs program can delete directories using the rmdir command.
   3833 
   3834 Add support for 8k and 16k filesystems (for systems with page sizes
   3835 that are greater or equal to 8k or 16k, respectively).  Note that
   3836 these filesystems can not be mounted on x86 systems, or other systems
   3837 with only 4k page sizes, due to limitations in the current Linux VM
   3838 code.
   3839 
   3840 Resize2fs requires that the filesystem state be valid and have no
   3841 errors; otherwise, e2fsck -f must be run first.  (Previously it simply
   3842 required that the last fsck time be greater than the last mount time.)
   3843 
   3844 Configure now defaults the man pages directory to /usr/share/man on
   3845 Linux systems.
   3846 
   3847 E2fsck now offers to truncate inodes which contain too many blocks (so
   3848 that i_blocks would overflow.  Also fixed handling of large sparse
   3849 files.
   3850 
   3851 E2fsck now more completely checks for symlink validity, including
   3852 requiring NULL termination and length checks.
   3853 
   3854 E2fsck will offer to try forcing a disk write to remap a bad block
   3855 after finding a read error when reading a filesystem metadata block.
   3856 
   3857 Fixed a bug in debugfs which caused the -b and -s options to crash
   3858 debugfs, as well as breaking the testb, setb, and clearb functions.
   3859 
   3860 Added a bmap command to debugfs which calculates the logical to
   3861 physical block mapping for a particular inode.
   3862 
   3863 Fixed a bug in code which checked to see if a device was mounted which
   3864 sometimes (rarely) failed in the case of a plain file.
   3865 
   3866 Fixed a bug in resize2fs where when it reported an error, it would
   3867 print a message erroneously indicating that the filesystem had been
   3868 resized before it aborted.
   3869 
   3870 When resizing a plain file which is smaller than the requested size,
   3871 resize2fs will attempt to extended the file so that programs like
   3872 e2fsck will not complain that the file is too small.
   3873 
   3874 Resize2fs will print the actual new size of the filesystem when it is
   3875 finished resizing.
   3876 
   3877 Fixed a bug in debugfs where "ls -l" would report incorrectl file type
   3878 information on big-endian systems.
   3879 
   3880 
   3881 Programmer's notes:
   3882 -------------------
   3883 
   3884 Fixed collisions with C++ reserved words.
   3885 
   3886 Added portability fixes for building e2fsprogs on the HURD and AIX.
   3887 
   3888 Added the ext2ed program for creation of test cases.  (ext2ed has many
   3889 limitations and bugs which make it unsuitable for production use.)
   3890 
   3891 The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
   3892 flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
   3893 name_len field is byte swampped on big-endian machines, since in the
   3894 V2 structure, name_len is a char field which is doesn't need to be
   3895 byte swapped --- except if an old-style kernel had byte-swapped the
   3896 name_len field as part of the V1 structure.
   3897   
   3898 
   3899 E2fsprogs 1.27 (March 8, 2002)
   3900 ==============================
   3901 
   3902 The warning messages for mke2fs now go to standard error.
   3903 
   3904 Fixed to make sure "make check" runs all of the test programs with
   3905 LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
   3906 
   3907 The mke2fs program checks the boot sector for the BSD disk label, and
   3908 avoids erasing it if it is there.
   3909 
   3910 Fixed a bug in e2fsck which caused it to core dump if the journal
   3911 inode was missing when it was supposed to be there.
   3912 
   3913 E2fsck now prints ranges in pass 5 when printing deltas for the block
   3914 and inode bitmaps.
   3915 
   3916 Debugfs's "ls -l" command now will print out the file type information
   3917 in the directory entry.
   3918 
   3919 Create man pages and hard links for fsck.ext3 and mkfs.ext3.  If
   3920 mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
   3921 
   3922 Debugfs can now examine the experimental directory indexing
   3923 information.
   3924 
   3925 Fixed bug in debugfs which caused it to core dump if modify_inode is
   3926 called without an open filesystem.
   3927 
   3928 The debugfs lsdel command now runs its output through a pager first.
   3929 
   3930 When installing manual pages, remove the compressed manual pages first.
   3931 
   3932 Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
   3933 
   3934 Fix the 2.4 resource limitation workaround introduced in 1.26 which
   3935 actually broke things on mips32, sparc32, and Alpha platforms.
   3936 
   3937 Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
   3938 (which is required by the newer libintl libraries).
   3939 
   3940 Programmer's notes:
   3941 -------------------
   3942 
   3943 Fixed various gcc -Wall complaints.
   3944 
   3945 Fixed a few memory leaks in the e2fsck journaling code, and in the
   3946 ismounted code checking for a swap device.
   3947 
   3948 Add new inode I/O abstraction interface which exports an inode as
   3949 an I/O object.
   3950   
   3951 Exported ext2_file_flush as a public interface.
   3952   
   3953 In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
   3954 
   3955 Lots of small random portability fixes to make e2fsprogs build under
   3956 AIX --- even without the 5L compatibility toolkit, and even using the
   3957 uber-crippled AIX native C compiler.
   3958 
   3959 
   3960 E2fsprogs 1.26 (February 3, 2002)
   3961 =================================
   3962 
   3963 Dumpe2fs will keep going now if the bad block inode can't be read.
   3964 (Previously it stopped with a fatal error.)
   3965 
   3966 E2fsck will now give an opportunity to run the journal even if the
   3967 recovery flag is not set.  This is the default behaviour if e2fsck is
   3968 using a backup superblock, since the needs_recovery flag will never be
   3969 set in the backup superblock copies.
   3970 
   3971 E2fsck now automatically finds the backup superblock/group descriptors
   3972 even when the primary superblock is completely destroyed for 2k and 4k
   3973 filesystems.  (Previously it just guessed/assumed that we were dealing
   3974 with a 1k filesystem in that case, and users had to manually specify
   3975 the backup superblock number.)
   3976 
   3977 Fixed a bug in e2fsck where it dereferences a null pointer when there
   3978 is a problem opening a filesystem in preen mode.
   3979 
   3980 E2fsck now handles external journals correctly; previously it trashed
   3981 the external journal device if the journal needed to be replayed.
   3982 
   3983 Work around ulimit incompatibility problem caused by recent 2.4
   3984 kernels; the unix IO module will automatically try to set any resource
   3985 limits to be infinite on startup.
   3986 
   3987 Fixed a bug in e2fsck where it wasn't allocating a new block or inode
   3988 bitmap if it wasn't present and the blocksize was 2k or 4k.
   3989  (Addresses Debian Bug #116975)
   3990 
   3991 E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
   3992 clearing the new V2 fields if they do not make sense or if the ext3
   3993 superblock is version 1 superblock.
   3994 
   3995 E2fsck will automatically relocate the ext3 journal from a visible
   3996 file (i.e., /.journal) to an hidden inode if the filesystem has been
   3997 opened read/write.  This allows the users to add a journal while the
   3998 filesystem is mounted, but the next time the system is rebooted, the
   3999 journal file will disappear.  This avoids problems with backups,
   4000 stupid operators with superuser bits, etc.
   4001 
   4002 Fix a bug in fsck where it would not support a filesystem type of
   4003 "auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
   4004 
   4005 Fsck now supports fstab entries of the form "ext3,ext2".  It will also
   4006 automatically identify reiserfs filesystems.
   4007 
   4008 The number of processes spawned by fsck can now be limited using the
   4009 FSCK_MAX_INST environment variable.
   4010 
   4011 Fsck now searchs the LVM proc hierarchy to find logical volumes which
   4012 should be searched for  UUID and label information.
   4013 
   4014 Work around a bug in 2.4.10+ kernels by trying to unset the filesize
   4015 limit if at all possible, when opening a block device.  (The filesize
   4016 limit shouldn't be applied against writes to a block device.)
   4017 
   4018 In mke2fs and e2fsck, specifying the -c option twice will now do
   4019 a read/write test on the disk.  Update the man pages to encourage
   4020 using the -c option, and to discouraging running badblocks separately,
   4021 since users tend to forget to set the blocksize when running 
   4022 badblocks.
   4023 
   4024 Mke2fs now automatically clears the immutable attribute on a
   4025 pre-existing .journal file left over from a previous failed attempt to
   4026 add a journal to an alreadyy-mounted filesystem.
   4027 
   4028 Fixed mke2fs's exit codes to consistently indicate when the mke2fs
   4029 operation failed.
   4030 
   4031 Mke2fs now creates the lost+found directory with permissions of 0700,
   4032 so that files that had previously lived in protected directory are
   4033 safe if they get dropped in lost+found and the system administrator
   4034 doesn't deal with immediately.  (Addresses Debian #bug 118443)
   4035 
   4036 Mke2fs and e2fsck (and all programs that use the
   4037 ext2fs_check_if_mounted function) will now properly identify that a
   4038 device is mounted, even in cases where devfs has confused things with
   4039 multiple devices names with the same identity, or if a dim-witted
   4040 system administrator has done something stupid like creating device
   4041 file aliases in their home directory.  Also now checks for swap devices
   4042 by using /proc/swaps.  (Addresses Debian bug #106622)
   4043 
   4044 Added a new option (-T) to tune2fs which sets the time a filesystem
   4045 was last checked.
   4046 
   4047 Speed up e2image when creating sparse raw image files by optimizing
   4048 away excess lseek() system calls.
   4049 
   4050 Fix support of large (> 2GB) files when used as a filesystem in
   4051 mke2fs, tune2fs, debugfs, and findsuper.
   4052 
   4053 Debugfs's stat and icheck commands now properly deals with large (>
   4054 2GB) files.
   4055 
   4056 Debugfs's set_super_value command now prints out the list of valid
   4057 superblock fields which can be set using the command.
   4058 
   4059 Debugfs's rm and kill_file command now updates the superblock free block
   4060 and inode counts, thus keeping the filesystem consistent.
   4061 
   4062 Debugfs's lsdel command now takes an optional argument which allows
   4063 the user to only see the most recently deleted files.
   4064 
   4065 A new command (undel) was added to debugfs which automates
   4066 undeleting a deleted inode and linking it back to a directory.
   4067 
   4068 Debugfs's ls command now takes a new option, -d, which lists 
   4069 deleted directory entries.
   4070 
   4071 Debugfs's testb, freeb, setb, and find_free_block commands now take an
   4072 optional count argument.
   4073 
   4074 Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
   4075 be used to signal that a particular inode should not be eligible for
   4076 tail-merging --- this is needed for programs like LILO.
   4077 
   4078 The findsuper (an unreleased, uninstalled utility program) has been
   4079 improved to add extra validity checks and to add a progress meter.
   4080 (It is still an unsupported program; the officially supported way to
   4081 recover from a trashed partition table is to use gpart; findsuper is
   4082 for wizards only.  :-)
   4083 
   4084 Debugfs was fixed to compile with "configure --disable-swapfs".
   4085 
   4086 Cleaned up various manual pages.   (Addresses Debian bug #119624, #120171)
   4087 
   4088 Added new translation file for Turkish.
   4089 
   4090 Programmer's notes:
   4091 -------------------
   4092 
   4093 Fix general gcc -Wall complaints.
   4094 
   4095 E2fsprogs (mostly) works with the dietlibc.
   4096 
   4097 The programming texinfo file has been expanded to include description
   4098 of additional libext2fs functions.  (Still not compeltely done, but a
   4099 lot of the more important functions have been documented.)
   4100 
   4101 Added a umask structure to struct_ext2_filsys, which currently only
   4102 modifies the behaviour of ext2fs_mkdir(), but if we add any file
   4103 creation functions to libext2fs, we should also make sure they respect
   4104 the umask setting.
   4105 
   4106 The build-rpm script was fixed to be a bit more safe.
   4107 
   4108 The tests' Makefile now has a way of automating test case creation 
   4109 for e2fsck, using "make testnew".
   4110 
   4111 Created a new function, ext2fs_dir_iterate2 which passes more
   4112 information to the callback function (identical to the one used by
   4113 ext2fs_dblist_dir_iterate).  The directory iterator functions take a
   4114 new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
   4115 directory entries.  If the directory entry is deleted, the callback
   4116 function will be called with the entry paraemter set to
   4117 DIRENT_DELETED_FILE.
   4118   
   4119 Added new functions, ext2fs_inode_alloc_stats and
   4120 ext2fs_block_alloc_stats, which takes updates block/inode allocation
   4121 statistics in the bitmaps, block group descriptors, and superblock
   4122 when inodes or blocks are allocated or deallocated.
   4123 
   4124 
   4125 E2fsprogs 1.25 (September 20, 2001)
   4126 ===================================
   4127 
   4128 This is primarily a bug-fix release; no new features were added, but
   4129 there are a number of embarassing bug fixes and cleanups applied.
   4130 
   4131 Fix a bug mke2fs which causes stack garbage to be written to disk when
   4132 zapping disk sectors.  (This bug could cause mke2fs to core dump for
   4133 some kernels, I suspect with security enhancement patches.)
   4134 
   4135 Remove unneeded #include of <linux/config.h> which was breaking
   4136 building e2fsprogs on the Hurd.  (Addresses Debian bug #112414.)
   4137 
   4138 Updated tune2fs man page to reflect the fact that adding or removing a
   4139 journal doesn't require running e2fsck.
   4140 
   4141 Remove use of AC_REQUIRE from autoconf which had been used to prevent
   4142 AC_CANONICAL_HOST from being called twice; unfortunately this causes
   4143 recent autoconf to bomb out since they don't allow AC_REQUIRE to be
   4144 used outside of autoconf macros.  Fortunately, it doesn't seem to be
   4145 necessary any more, anyway.
   4146 
   4147 E2fsck will now not fall back to an alternate superblock if the user
   4148 specifies the superblock location explicitly on the command-line.
   4149 This allows easier recovery from a situation where the primary
   4150 superblock and block groups are slightly corrupted, but the backup
   4151 superblocks are completely broken.  
   4152 
   4153 Fix problem which caused compile_et and mk_cmds to blow up if
   4154 e2fsprogs was in a directory with a pathname that contained spaces.
   4155 
   4156 We are now more paranoid about checking the entry in /etc/mtab to make
   4157 sure the filesystem is really mounted, since some broken distributions
   4158 (read: Slackware) don't initialize /etc/mtab before checking non-root
   4159 filesystems.  (Slackware also doesn't check the root filesystem
   4160 separately, and reboot if the root filesystem had changes applied to
   4161 it, which is dangerous and broken, but there's nothing I can do about
   4162 that.)
   4163 
   4164 Make UUID library C++ friendly by adding appropriate extern "C"
   4165 declarations and using const in the function declarations.
   4166 
   4167 Fix up the com_err texinfo file so that it can product a valid info
   4168 file (previously, it could only be used to generate paper
   4169 documentation using texinfo.tex).
   4170 
   4171 
   4172 E2fsprogs 1.24a (September 2, 2001)
   4173 ===================================
   4174 
   4175 Fix brown-paper bug in mke2fs which caused it to segfault when
   4176 printing the version string.
   4177 
   4178 
   4179 E2fsprogs 1.24 (August 30, 2001)
   4180 ================================
   4181 
   4182 Revert the BLKGETSIZE64 support, since for some distributions, this
   4183 ioctl has been used by an unofficial kernel patch to update the last
   4184 sector on the disk, and this was causing disk corruption problems as a
   4185 result.
   4186 
   4187 Mke2fs is now more careful about zapping swap space signatures and
   4188 other filesystem/raid superblock magic values so that programs like
   4189 mount who try to use hueristics to determine the filesystem type of a
   4190 partition are less likely to be confused.
   4191 
   4192 E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
   4193 regular file (since Andreas Dilger's on-line resizing tools will set
   4194 its mode bits).
   4195 
   4196 Fixed some minor texinfo, man pages nits for spelling errors,
   4197 texinfo warnings, etc.  (Addresses Debian bug #110621.)
   4198 
   4199 E2fsprogs program no longer print the filesystem version number
   4200 (i.e. 0.5b), since it only confuses people and doesn't serve any real
   4201 purpose.
   4202 
   4203 E2fsck will once again compile under libc5, since it will supply its
   4204 own version of strnlen if necesssary.
   4205 
   4206 mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
   4207 when specifying the external journal device.  tune2fs will also search
   4208 devices looking for the externla journal debice when removing.  
   4209 
   4210 E2fsprogs 1.23 (August 15, 2001)
   4211 ================================
   4212 
   4213 Add initial support for extended attributes (EA); e2fsck will
   4214 correctly handle a filesystem with EA's and check the EA blocks for
   4215 corruptions.
   4216 
   4217 E2fsck's symlink sanity checking has been cleaned up.  It now checks
   4218 the i_size value of fast symlinks, and checks for immutable flags
   4219 being set of symlinks, etc.
   4220 
   4221 E2fsck now offers to clear inodes which are special files that have a
   4222 non-zero i_blocks or i_size field.  (The i_size field check was in the
   4223 previous version of the code, but due to a bug it didn't offer to
   4224 clear the inode unless i_size and i_size_high were both non-zero.)
   4225 
   4226 E2image can now create "raw" image files, which only contain the
   4227 filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
   4228 debugfs, etc., can be run directly on the raw image file.
   4229 
   4230 Add support for the 64-bit block device patches.
   4231 
   4232 Fixed bugs in creating external journals with a 1k blocksize.
   4233 
   4234 Add initial support for external journals (so long as the external
   4235 journal only supports a single filesystem) in e2fsck.
   4236 
   4237 Remove requirement for needing to run fsck on a filesystem after
   4238 removing a journal (either internal or external).
   4239 
   4240 The man pages now document how to create and manage external journals.
   4241 
   4242 Speed up the check of an ext3 filesystems by avoiding a needless flush
   4243 of all of the superblock and block group descriptors.
   4244 
   4245 Speed up creating an internal journal using tune2fs in the case where
   4246 the filesystem has a lot blocks already allocated.
   4247 
   4248 Tune2fs has been fixed to make sure that only error messages go to
   4249 stderr, and normal message go to stdout. (Addresses Debian bug #108555)
   4250 
   4251 Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
   4252 now not set the sparse_super feature.  (Addresses Debian bug #108165)
   4253 
   4254 Add support in fsck for the filesystem type "auto".
   4255 
   4256 Fsck -A will not try to interpret device names for filesystems which
   4257 have a pass number is 0.  (Addresses Debian bug #106696).
   4258 
   4259 Fsck prints a warning message if now valid filesystems are passed to
   4260 it.  (Addresses Debian Bug #107458.)
   4261 
   4262 E2fsck now gives an explicit warning if there filesystem still has
   4263 errors at the end of the run. (Addresses Debian bug #104502)
   4264 
   4265 E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
   4266 reflects an error.  E2fsck will also not run the orphan list if the
   4267 filesystem contains errors, since the orphan list might be corrupted.
   4268 
   4269 E2fsck now prints the number of large files when given the -v option.
   4270 
   4271 Fixed minor memory leaks in e2fsck.
   4272 
   4273 Some minor man pages updates. (Addresses Debian bug #30833, #108174)
   4274 
   4275 
   4276 E2fsprogs 1.22 (June 22, 2001)
   4277 ==============================
   4278 
   4279 Fixed a bug in e2fsck's handling of orphan inodes which are special
   4280 files (i.e., block/character device files, named FIFO's, etc.).
   4281 
   4282 Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
   4283 tune2fs to fail at adding a journal to a mounted filesystem.
   4284 
   4285 Fixed a few big-endian bugs in e2fsprogs
   4286 	* The directory block functions were accidentally reporting
   4287 		some directories as corrupted when they weren't.
   4288 	* If e2fsprogs is compiled --disable-swapfs, the C language 
   4289 		equivalents weren't being included for big-endian platforms.
   4290 		(Fixes Debian bug #101686).
   4291 
   4292 Fixed a Hurd compilation problem.  (Addresses Debian bug #101361)
   4293 
   4294 Programmer's notes:
   4295 -------------------
   4296 
   4297 Use platform independent method of defining the BLKFLSBUF and FDFLUSH
   4298 ioctls, and allow them to be defined for non-i386 platforms.
   4299 
   4300 The uuid.h header file is now protected against multiple inclusions.
   4301 
   4302 E2fsprogs is now being developed using BitKeeper.  Changed the test
   4303 scripts to deal with BK's stripping CR characgters from text files,
   4304 and changed the top-level Makefile.in to avoid including BitKeeper
   4305 files when generating the source tarball.
   4306 
   4307 
   4308 E2fsprogs 1.21 (June 15, 2001)
   4309 ==============================
   4310 
   4311 Added new configure flags which allow a subset e2fsprogs to be built;
   4312 this is most useful for boot floopies, since the resulting shared
   4313 libraries and programs are slimmed down by removing features that
   4314 aren't necessary for a boot floppy.  The new flags that were added
   4315 are: --disable-swapfs, which removes support for byte swapping old
   4316 legacy PPC/68k filesystems, --disable-debugfs, which removes support
   4317 for debugfs from the libext2fs library, --disable-imager, which
   4318 removes support for the e2image program, and --disable-resizer, which
   4319 removes support for resize2fs.
   4320 
   4321 E2fsck now prints the number of mounts or days elapsed since the last
   4322 check when e2fsck is forced to check an otherwise clean filesystem.
   4323 
   4324 Tune2fs now prints an informative message about how often a filesystem
   4325 will be checked when adding a journal to the filesystem, to remind the
   4326 user that he/she may want to adjust those parameters using tune2fs
   4327 -c/-i.
   4328 
   4329 Worked around hurd brain-damage which causes e2fsck to sometimes
   4330 believe a filesystem is the root filesystem based on device numbers
   4331 (since Hurd doesn't have dev_t's, which is arguably a POSIX.1
   4332 violation).
   4333 
   4334 Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
   4335 erroneous error with the -F option was specified.
   4336 
   4337 Fixed a ext3 recovery bug in the revoke handling; synchronized with
   4338 ext3 0.7a.
   4339 
   4340 Fixed two bugs in e2fsck's handling of dup block handling, dealing
   4341 with relatively uncommon edge cases: a directory with an indirect
   4342 block which is claimed by another file, and when the last inode in the
   4343 filesystem has blocks claimed by another file.
   4344 
   4345 E2fsck now checks to see if the i_size field of a fast symlink is too
   4346 big, and offers to clear the symlink if so.
   4347 
   4348 E2fsck now checks to see if i_size_high of special files is non-zero,
   4349 and offers to clear i_size_high.
   4350 
   4351 Fix e2fsck's handling of incompatible journal flags so that the user
   4352 has chance to abort, and then has the option to clear out the journal
   4353 entirely.  (Addresses Debian bug #98527.)
   4354 
   4355 Fixed a bug in fsck which could cause it to core dump if a mix of
   4356 standard and non-standard device names are used in /etc/fstab.
   4357 (Debian bug #100559)
   4358 
   4359 Fixed a bug in debugfs which caused read errors when copying a file to
   4360 not be noticed.
   4361 
   4362 The debugfs set_super_value command can now modify the s_lastcheck field.
   4363 
   4364 Fixed a bug in lsattr and chattr which was accidentally introduced in
   4365 1.20 to support > 2GB files; both lsattr and chattr wasn't reading
   4366 directories correctly because the change modified the layout of struct
   4367 dirent to be incompatible with the libe2p shared library.
   4368 
   4369 Cleaned up the mke2fs manual page and included a discussion about why
   4370 it's good to periodically check the filesystem even when journaling is
   4371 enabled.
   4372 
   4373 Programmer's notes:
   4374 -------------------
   4375 
   4376 Fix general gcc -Wall complaints.
   4377 
   4378 The types needed by the ext2 header files are now provided by
   4379 lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
   4380 
   4381 Integers are now preferred to longs when trying to find a 32-bit type
   4382 in ext2_types.h.  Also, if linux/types.h has already been defined,
   4383 don't try to redefine the types.
   4384 
   4385 Fixed make depend script so that it automatically corrects the
   4386 pathname cleanups performed by make -M, so I don't have to fix them up
   4387 by hand.
   4388 
   4389 Fixed the d_loaddump test case to be more robust, and not depend on
   4390 bash'isms.
   4391 
   4392 Removed debugfs's dependence on pread(), which was accidentally
   4393 intrudced in e2fsprogs 1.20
   4394 
   4395 Fixed a performance bug in the libext2fs's icount routine; the size
   4396 estimate of the icount array was incorrectly being calculated.
   4397 
   4398 Removed use of the badblocks compatibility functions in the e2fsprogs
   4399 programs.
   4400 
   4401 Added paranoia code which protects against strange cases where /etc
   4402 isn't on the root filesystem, or if /etc/mtab doesn't exist.
   4403 
   4404 The header file ext2_types.h is now installed.
   4405 
   4406 Autoconf is used to determine when we are on big-endian machines,
   4407 instead of doing run-time tests, to save a few bytes of code.
   4408 
   4409 The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
   4410 functions are no longer inline functions, which saves space and
   4411 doesn't really cost any real performance.
   4412 
   4413 The ext2fs library no longer depends on the e2p library.  (What need
   4414 there was of it --- namely, fsetflags, was coded in-line).
   4415 
   4416 Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
   4417 when the user is stupid and tries compiling the package using "make
   4418 install" as root.
   4419 
   4420 Miscellaneous code cleanups:
   4421 	* Added missing files from Makefile.in's SRCS file, so that 
   4422 		their dependencies would be properly calculated.
   4423 	* Removed redundant code
   4424 	* Fixed comments in code
   4425 	* Removed no-longer unneeded argsused #pragma.
   4426 
   4427 
   4428 E2fsprogs 1.20 (May 20, 2001)
   4429 =============================
   4430 
   4431 Add support for replaying the ext3 journal purely in user mode,
   4432 including handling the orphaned inode list.  Used code contributed by
   4433 Andreas Dilger, with bug fixes and the orphaned inode handling done
   4434 by Theodore Ts'o.
   4435 
   4436 The mke2fs and tune2fs programs can create or modify a filesystem to
   4437 include an ext3 journal.  Tune2fs also can be used to remove an ext3
   4438 journal from a filesystem.
   4439 
   4440 E2fsck will now check for the existence of a linked list of orphan
   4441 inodes in the superblock, and clear those inodes before starting the
   4442 rest of the filesystem check (but after the journal playback).
   4443 
   4444 E2fsck now validates the file descriptor passed to the -C option,
   4445 which saves against the completion bar getting written to an
   4446 unexpected location, such as the disk being checked.  (Debian
   4447 bug/wishlist #55220)
   4448 
   4449 E2fsck will now bump the filesystem revision number from zero to one
   4450 if any of the compatibility bits are set.
   4451 
   4452 Fixed a bug where a badly corrupted directory on a big endian system
   4453 could cause e2fsck to die with a bus error.  The
   4454 ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
   4455 the ext2 library now does alignment sanity checks on the rec_len field
   4456 of the directory entry before using it.
   4457 
   4458 The ext2 library has been enhanced to make tune2fs safe to run on
   4459 mounted filesystems.  (Users could usually get away with using tune2fs
   4460 on mounted filesystems before, but with the advent of ext3 and
   4461 journaling, it became important to make tune2fs was *really* safe for
   4462 use even when the filesystem being modified is mounted.)  E2label is
   4463 now implemented by tune2fs using an argv[0] dispatch, so that e2label
   4464 is also now safe for use on mounted filesystems.
   4465 
   4466 Added a new program, e2image, which creates a backup of critical ext2
   4467 filesystem data structures.  The generated image file can be examined
   4468 using dumpe2fs and debugfs.  In the future, e2fsck will be able to use
   4469 the image file to help recover very badly damaged filesystems.
   4470 
   4471 Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
   4472 no longer cause e2fsck to bomb out.  Also treat files > 2GB as being
   4473 large file when deciding whether or not the filesystem has large files.
   4474 
   4475 Fixed lsattr and chattr so that they work correctly on large files.
   4476 (Fixes Debian bug #72690.)
   4477 
   4478 Removed limitation in get_device_size() which imposed a one terrabyte
   4479 filesystem limitation.  (Most 2.2 kernels still have a signed int
   4480 problem which cause 1 TB block device limitation.  Fortunately, the
   4481 kernel patches to fix this are much easier than fixing the 2TB
   4482 limitation in the kernel.  :-)
   4483 
   4484 A max_mount_count of zero is now treated as if no mount count were
   4485 set.  (Previously, no mount count was indicated by using -1, and a
   4486 mount count of zero caused e2fsck to always be run.)
   4487 
   4488 Mke2fs supports two new filesystem types largefile and largefile4.
   4489 
   4490 Mke2fs now adds some randomness in s_max_mount_count so that multiple
   4491 filesystems won't be all checked at the same time under normal
   4492 operations.
   4493 
   4494 Fixed bug in the progress bar printing code which could cause e2fsck
   4495 to core dump on an illegal filesystem.
   4496 
   4497 Fixed bug in fsck which could allow more than one instance of e2fsck
   4498 to be printing a progress bar.  (Debian bug #65267)
   4499 
   4500 Fsck using a UUID or a LABEL specifier will work even if devfs is
   4501 compiled into the kernel and not mounted.  If the pathnames in
   4502 /proc/partitions are incorrect, fsck will search /dev for the correct
   4503 device (using the new ext2fs_find_block_device library function).
   4504 Fsck now also checks the RAID devices first so that they are properly
   4505 found when they are in use.  Support has also been added to support
   4506 additional IDE disks and the DAC 960 device names.  (Debian bug #94159)
   4507 
   4508 Fixed a bug in fsck which caused it not deal properly with 16
   4509 byte long filesystem labels.
   4510 
   4511 Fsck's -t option has been made a lot more flexible.  The semantics for
   4512 what happens if a comma-separated list to fsck has been regularized,
   4513 and it is now possible to filter what filesystems will get checked
   4514 based what is in the filesystem's fstab entry's option field.  (Debian
   4515 bug #89483.)
   4516 
   4517 The dumpe2fs program can now print out the group description
   4518 information in hex, and also prints the location of the superblock and
   4519 block group descriptor for those block groups that have them.
   4520 
   4521 Mke2fs now clears the ext2 superblock before it starts creating a
   4522 filesystem, so that the superblock magic number is only written if the
   4523 filesystem creation process successfully completes.
   4524 
   4525 The debugfs program's stat command now pretty-prints the blocks used
   4526 by an inode so that it's more compact and informative.
   4527 
   4528 The debugfs stats command now uses the same libe2p code (which is used
   4529 by dumpe2fs) to print the superblock header information.  This is more
   4530 complete, and it avoids a bit of code duplication.
   4531 
   4532 Added a new debugfs command, set_super_value (ssv) which allows the
   4533 user to set arbitrary superblock fields.
   4534 
   4535 Debugfs was extended to support inode numbers in hex (by prefixing
   4536 them with 0x), and so that modify_inode can set the inode generation
   4537 number.  Also, there is now a new function command called logdump
   4538 which will dump an ext3 journal.
   4539 
   4540 Fixed a bug in debugfs so that quitting out of the pager doesn't kill
   4541 debugfs.
   4542 
   4543 Debugfs's dump command now stops immediately upon reporting a disk
   4544 read error.  (Fixed a bug in ext2fs_file_read library routine which
   4545 caused debugfs not to stop.)  (Debian bug #79163)
   4546 
   4547 On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
   4548 checked before /etc/mtab is used, since /proc/mounts is more likely to
   4549 be accurate.
   4550 
   4551 Added portability fixes for Solaris and Linux/ia64.
   4552 
   4553 Various manual pages were clarified and cleaned up.  (Fixed debian
   4554 bugs #63442, #67446, and #87216)
   4555 
   4556 
   4557 Programmer's notes:
   4558 -------------------
   4559 
   4560 The e2fsck message printer now supports %Iu and %Ig, which will print
   4561 out the inode's user and group owners, respectively.
   4562 
   4563 E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
   4564 that no longer dependent on the system having the correct version of
   4565 the kernel header files.
   4566 
   4567 Added a new function to libext2, ext2fs_find_block_device(), which
   4568 searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
   4569 device given its device number.
   4570 
   4571 Added a new function to libext2, ext2fs_sync_device, which centralizes
   4572 all of the places which might try to use the BLKFLSBUF or FDFLUSH
   4573 ioctls (and usually failing to define them since the system header
   4574 files don't usually do this for us, and we're trying to avoid usage of
   4575 kernel include files now).
   4576 
   4577 Added new utility programs in tests/progs: random_exercise and
   4578 hold_inode.  They aren't built by default; they're useful for
   4579 exercising ext3 filesystem code.
   4580 
   4581 Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
   4582 the filesystem close functions to only update the superblock, and to
   4583 not touch the block group descriptors.  Needed by tune2fs when
   4584 modifying a mounted filesystem.
   4585 
   4586 Got rid of struct ext2fs_sb and replaced it with the standard struct
   4587 ext2_super_block from include/linux/ext2_fs.h.  Note: this may break
   4588 source (but not binary) compatibility of some users of the ext2
   4589 library.  Those applications should just simply do a global search and
   4590 replace of struct ext2fs_sb with struct ext2_super_block, and include
   4591 the new header file <ext2fs/ext2_fs.h> which defines it.
   4592 
   4593 The ino_t type has been renamed ext2_ino_t to protect applications
   4594 that attempt to compile -D_FILE_OFFSET_BITS=64, since this
   4595 inexplicably changes ino_t(!?).  So we use ext2_ino_t to avoid an
   4596 unexpected ABI change.
   4597 
   4598 The Makefiles have been reworked so that "make check" can be run from
   4599 the top-level Makefile.
   4600 
   4601 Fix general gcc -Wall complaints and removed dead code.
   4602 
   4603 Remove use of NOARGS, because we assume everyone does ANSI C these
   4604 days.
   4605 
   4606 Added build-rpm script from sct.
   4607 
   4608 New functions ext2fs_image_{inode,super,bitmap}_{read,write} added 
   4609 to support e2image.
   4610 
   4611 New function ext2fs_flush_icache which must be called if the
   4612 application program modifies the inode table blocks without going
   4613 through ext2fs_write_inode() interface.
   4614 
   4615 New ext2fs_check_mount_point() function, which will return the mount
   4616 point of a device if mounted.
   4617 
   4618 The io_channel abstraction now has an optional interface,
   4619 io_channel_write_range, which allows specific byte ranges to be
   4620 written.  
   4621 
   4622 The unix_io IO channel now supports write-through caching, so that
   4623 journal creation is more efficient.
   4624 
   4625 Added x86 assembly language routines to support byte swapping, to
   4626 reduce executable size.
   4627 
   4628 Fixed bug in the utility program subst so that it's possible to
   4629 replace a substitution variable with a zero-length string.
   4630 
   4631 Fixed numbering e2fsck pass1 problem numbers; an extra zero had
   4632 slipped into some of the problem number.
   4633 
   4634 E2fsprogs 1.19 (July 13, 2000)
   4635 ==============================
   4636 
   4637 Release the resize2fs program since the timeout before it could
   4638 be released under the GPL has finally expired.
   4639 
   4640 Add experimental support needed for the ext2 compression patches.
   4641 This requires compiling e2fsprogs with the --enable-compression flag
   4642 to the configure script.
   4643 
   4644 Added ext3 journalling support.  E2fsck will run the journal (if
   4645 necessary) by temporarily mounting the filesystem.  /sbin/fsck.ext3 is
   4646 installed as a symlink to e2fsck.  Fsck has been taught about ext3,
   4647 and treats it the same as ext2 in terms of the progress bar logic.
   4648 Dumpe2fs will display the superblock journaling information if the
   4649 filesystem has a journal.  The ext2 library will now permit opening an
   4650 ext3 filesystem with the recovery flag set.  This is necessary for
   4651 on-line dump's to work correctly, but there may be issues with this
   4652 working well since ext3 is much less agressive about syncing blocks to
   4653 the filesystem, since they're safe on the journal.
   4654 
   4655 Tune2fs and e2fsck have been changed to allow the mount_count check to
   4656 be disabled by setting max_mount_count to -1.  (This was already
   4657 supported by the kernel.)
   4658 
   4659 Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
   4660 are used for ext3 as well.
   4661 
   4662 Added internationalization support for e2fsprogs; must be enabled
   4663 by passing --enable-nls to configure.
   4664 
   4665 Always use the provided ext2fs header files to insulate ourselves from
   4666 kernel version changes.  Which include files are used by e2fsprogs
   4667 have also been cleaned up to improve portability.
   4668 
   4669 Limit the number of times that e2fsck updates the progress bar so that
   4670 people who are booting using a 9600 baud console don't get swampped by
   4671 too many updates.
   4672 
   4673 Improved the loop detection algorithm in e2sck's pass #3 so that it is
   4674 much, much faster for large filesystems with a large number of
   4675 directories.
   4676 
   4677 The memory footprint for e2fsck is now slightly smaller than before.
   4678 
   4679 E2fsck now checks if special devices have a non-zero size, and offers
   4680 to clear the size field if it finds such an inode.  
   4681 
   4682 E2fsck now checks if special devices have the append-only flag set,
   4683 and offers to clear the inode.
   4684 
   4685 E2fsck now properly handles some "should never fail" cases during a
   4686 bitmap copy in pass5.
   4687 
   4688 E2fsck now properly prints control characters in filenames as ^A .. ^Z.
   4689 
   4690 E2fsck now calculates the correct location of the backup superblock in
   4691 the case of filesystem blocksizes > 1k.
   4692 
   4693 Fixed a bug in e2fsck's calculation of the number of inodes_per_block
   4694 which normally didn't cause problems under most filesystem parameters,
   4695 but could cause a valid superblock to be rejected in extreme cases.
   4696 Other checks for validating superblock values were made more
   4697 stringent.
   4698 
   4699 Added non-destructive write testing to the badblocks program, courtesy
   4700 of David Beattie.  The badblocks also now has an option to input the
   4701 current set of bad blocks, so that known bad blocks are skipped to
   4702 speed up the badblocks test.  There is also a persistent rescan
   4703 feature which causes badblocks to run until it has completed some
   4704 number of passes without discovering any new bad blocks.
   4705 
   4706 Badblocks now checks to see if the device is mounted and refuses to do
   4707 the tests involving writing to the device if it is mounted.  Also,
   4708 badblocks now allows the number of blocks to be checked to be
   4709 defaulted to the size of the partition.
   4710 
   4711 Fixed a bug in fsck which didn't allow non-root users to be able to
   4712 check filesystems if there were any LABEL= or UUID= entries in
   4713 /etc/fstab.
   4714 
   4715 The Hurd doesn't support the filetype filesystem feature.  The mke2fs
   4716 program now makes sure that for the Hurd, the filestype feature is
   4717 turned off.  E2fsck will check to see if the filetype feature is
   4718 turned on for Hurd filesystems, and offer to turn off the feature.
   4719 
   4720 Mke2fs now has a safety check to make sure the number of blocks do not
   4721 exceed 32 bits even on a 64 bit platform.
   4722 
   4723 Really fixed a bug in fsck to allow "fsck -As" to run interactive
   4724 fsck's.  (For those people who like to do interactive fsck's in the
   4725 /etc/rc scripts!?!)
   4726 
   4727 Debugfs has a few new features: the rdump command, which will do a
   4728 recursive dump of a directory and all of its contents, and the lcd
   4729 command which does a local chdir (much like the ftp command of the
   4730 same name).  In addition, the debugfs program and the open_filesystem
   4731 command now takes three new options: -b and -s, which allows the
   4732 blocksize and superblock location to be specified, and the -c option
   4733 which is used in catastrophic situations where the block group
   4734 descriptors are corrupt.  If the -c option is specified, debugfs will
   4735 skip trying to read in the block and inode bitmaps.
   4736 
   4737 Debufs's lsdel command was fixed to handle bad blocks in the inode
   4738 table.
   4739 
   4740 A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
   4741 4 digit years.
   4742 
   4743 General improvements in error messages
   4744 
   4745   - Mke2fs prints a sane error message if the partition size is zero
   4746 	(usually because the partition table wasn't reread by the
   4747 	kernel due to the partition being busy), instead of "invalid
   4748 	argument passed to ext2 library while initializing superblock".
   4749 
   4750   - Fsck now prints more self-explanatory message if an invalid UUID=
   4751 	or LABEL= specification is passed to it.
   4752 
   4753 UUID library changed to use the LGPL.
   4754 
   4755 Fixed a bug in the UUID library where very rapid calls to the
   4756 time-based UUID generator could cause duplicate UUID's to be returned.
   4757 This was not a problem for e2fsprogs, but it could be a problem for
   4758 other users of the library.
   4759 
   4760 Make the UUID library more robust in the face of missing or an
   4761 improper /dev/urandom or /dev/random files.
   4762 
   4763 Added some random portability fixes for Solaris.
   4764 
   4765 Some minor man page updates.
   4766 
   4767 Fixed a memory leak in the ss library.
   4768 
   4769 
   4770 Programmer's notes:
   4771 -------------------
   4772 
   4773 We now try to use lseek64 and open64 from the LFS if possible.
   4774 
   4775 The 3rd parameter in e2p's print_flags is now a flags word, instead of
   4776 a boolean option.
   4777 
   4778 The mark and unmark bitmap functions now return the previous state of
   4779 the bit that was being changed, which is useful for some speed
   4780 optimizations.
   4781 
   4782 The following functions have been added to enhance the badblocks list
   4783 handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
   4784 ext2fs_badblocks_equal.
   4785 
   4786 The ext2 header files now have the latest journalling fields to the
   4787 superblock.
   4788 
   4789 The ext2fs_mkdir function in libext2fs now properly backs out of error
   4790 conditions robustly.
   4791 
   4792 Cleaned up makefiles:
   4793   - to cleanly  compile with the -j flag.
   4794   - so distclean removes all generated files.
   4795   - so in case of an error while installing header files, the make aborts.
   4796 
   4797 Fix test_script so that it works correctly when compiling in the
   4798 source directory.
   4799 
   4800 The random UUID generation routine has been made slightly better in
   4801 the case where /dev/random doesn't exist.  (Use of randomly-based UUID
   4802 is still not recommended if /dev/random doesn't exist, however; it's
   4803 better to use the time/ethernet MAC address UUID in this case.)
   4804 
   4805 Clean up the build process so it's more friendly in case of missing
   4806 directories.
   4807 
   4808 The ext2fs header file can now be #include'd into C++ programs.
   4809 
   4810 The e2p.h header file is now installed.
   4811 
   4812 Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
   4813 
   4814 
   4815 
   4816 E2fsprogs 1.18 (November 10, 1999)
   4817 ==================================
   4818 
   4819 Fix a core dumping bug in e2fsck if an imagic inode is present or
   4820 (more rarely) if the filesystem is badly corrupted enough that e2fsck
   4821 has to restart pass 1 processing.  E2fsck now closes the filesystem
   4822 before freeing a large number of its data structures, so in the case
   4823 of future memory faults, at least the fixed filesystem will be fully
   4824 written out.
   4825 
   4826 If a filesystem doesn't support imagic inodes, and e2fsck discovers an
   4827 imagic inode, it will offer to clear the imagic flag.
   4828 
   4829 E2fsck will now offer to clear the immutable flag on special files
   4830 (device/socket/fifos) when running it in non-preen mode.
   4831 
   4832 E2fsck will now set the filetype when creating /lost+found, and when
   4833 connected orphaned inodes to /lost+found.
   4834 
   4835 Debugfs's ncheck and icheck commands now handles the case where there
   4836 are bad blocks in the inode table without bombing out.
   4837 
   4838 The badblocks list processing code has been made more efficiently for
   4839 appending a large number of (ordered) badblocks to the badblocks list.
   4840 
   4841 Some minor man page updates.
   4842 
   4843 Fsck now allows interactive e2fsck's when using fsck -As (not a common
   4844 mode, but some people like to do this in boot scripts for silly reasons).
   4845 
   4846 Programmer's notes:
   4847 -------------------
   4848 
   4849 The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
   4850 with the problem code convention.
   4851 
   4852 The badblocks list regression test program has been updated to work
   4853 with previously made API name changes.
   4854 
   4855 The ext2fs_free() command now uses the new badblocks API to avoid
   4856 using the compatibility layer.
   4857 
   4858 Added new regression test cases; the run_e2fsck test script now
   4859 supports the ability for a test case to run a prepratory command
   4860 before running e2fsck.
   4861 
   4862 E2fsprogs 1.17 (October 26, 1999)
   4863 =================================
   4864 
   4865 Fixed nasty typo in fsck which caused parallelized fsck's to go into an
   4866 infinite loop.
   4867 
   4868 Fixed a bug in fsck where it used strncmp to compare a binary UUID,
   4869 thus potentially causing problems if a binary UUID contained a NULL
   4870 character.
   4871 
   4872 E2fsck now uses stricter checks for directory entries in pass 2:
   4873 zero-length filenames are not allowed; neither are 8 byte long
   4874 directory entries.
   4875 
   4876 The debugfs "dirty" command now clears the filesystem valid bit.
   4877 (Previously this just set the dirty-as-in-needs-writing-out-to-disk
   4878 bit in the in-core superblock image.  The new functionality is more
   4879 what the user expects, and is more useful.)
   4880 
   4881 Added a debugging hook to test parallel fsck; if the environment
   4882 variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
   4883 will be checked in parallel when they normally would not be.
   4884 
   4885 Programmer's notes:
   4886 -------------------
   4887 
   4888 Fixed some #ifdef's for compilation under the Hurd OS.
   4889 
   4890 Fixed minor W2K compatibility problems.
   4891 
   4892 Fixed some miscellaneous GCC warnings.
   4893 
   4894 
   4895 E2fsprogs 1.16 (October 22, 1999)
   4896 =================================
   4897 
   4898 Fixed a race condition bug in fsck; when printing a progress bar, if
   4899 checking multiple filesystems in parallel, it was possible for fsck to
   4900 send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
   4901 handler, which would cause it to terminate with a signal 10.
   4902 
   4903 E2fsck now properly handles filesystems that have the
   4904 INCOMPAT_FILETYPE feature turned on.  It can be used to convert a
   4905 filesystem into using or not using FILETYPE feature.
   4906 
   4907 E2fsck now properly handles filesystems that have the IMAGIC feature
   4908 turned on (this is used on Linux AFS servers).
   4909 
   4910 The mke2fs program now creates filesystems that have the filetype and
   4911 sparse_superblock features enabled by default, unless it is run on a
   4912 pre-2.2 kernel.  These features are not supported by a pre-2.2 kernel,
   4913 so there is now a new flag -O which allows the user to specify with
   4914 which features she would like to create the filesystem; "mke2fs -O
   4915 none" will create a filesystsem compatible with 2.0 kernels.
   4916 
   4917 The tune2fs program now has a -O option which allows the user to set
   4918 and reset "safe" filesystem features.  Currently, the only ones which
   4919 allows to be modified are the filetype and sparse_superblock features.
   4920 Note setting or clearing either feature will require running e2fsck on
   4921 the filesystem afterwards.  (n.b. Clearing the sparse_superblock feature
   4922 requires that there is enough free space on the filesystem for the
   4923 extra superblocks which will be created by e2fsck.)
   4924 
   4925 Debugfs can now set and print filesystem features in the superblock
   4926 using the "features" command.  Dumpe2fs will print out the complete
   4927 set of features when listing the superblock.
   4928 
   4929 Dumpe2fs has new options -f (force) and -h (header-only).
   4930 
   4931 Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
   4932 message to come up.  This could happen when decrementing or
   4933 incrementing a link count could result in an overflow.
   4934 
   4935 Fixed a bug in e2fsck where the block count on the lost+found
   4936 directory would not be properly incremented when the directory was
   4937 expanded to the point where an indirect block needed to be allocated.
   4938 
   4939 E2fsck now makes some additional sanity checks on the superblock to
   4940 avoid crashing or giving a memory allocation error if some of the
   4941 values in the superblock are unresonable (but the superblock otherwise
   4942 looks valid).
   4943 
   4944 Fixed a bug in e2fsck where a very badly corrupted filesystem might
   4945 require two passes to completely fix the filesystem.  This happened if
   4946 an inode claimed blocks that was part of the filesystem metadata
   4947 (typically, when garbage was written into an inode table or indirect
   4948 block, since this kind of filesystem corruption normally doesn't
   4949 happen otherwise).
   4950 
   4951 On the Alpha, glibc declares st_flags although it isn't actually used;
   4952 the configure script was improved to detect this case so that
   4953 e2fsprogs can avoid using the non-functional stat field.
   4954 
   4955 The manual pages were updated to use a more consistent formatting
   4956 style consistent with standard Unix man pages.  Mke2fs's man page
   4957 added documentation for a few previously undocumented options.
   4958 
   4959 Fixed minor display bugs in tune2fs and mke2fs.
   4960 
   4961 Programmer's notes:
   4962 -------------------
   4963 
   4964 Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
   4965 
   4966 Added features to parse and print feature strings into the e2p library.  
   4967 (e2p_feature2string, e2p_string2feature, e2p_edit_feature).
   4968 
   4969 ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
   4970 whose directory entries contain proper filetype information if the
   4971 filesystem supports it.
   4972 
   4973 ext2fs_link() now uses the low 3 bits of its flags parameter to pass
   4974 the directory entry filetype information.  This is used to set the
   4975 directory entry filetype information if the filesystem supports it.
   4976 
   4977 Fixed a bug in ext2fs_expand_dir() where the block count in a
   4978 directory's inode would not be properly incremented when the directory
   4979 was expanded to the point where an indirect block needed to be
   4980 allocated.
   4981 
   4982 
   4983 E2fsprogs 1.15 (July 18, 1999)
   4984 ==============================
   4985 
   4986 Add configuration checks so that e2fsprogs will compile cleanly on
   4987 Linux 2.3 kernels that have renamed i_version to i_generation.
   4988 
   4989 E2fsck now prints a progress/completion bar (and not just a simple
   4990 spinner) if the -C0 option is requested or if it receives a SIGUSR1
   4991 signal.  Fsck will automatically manage the (potentially muliple)
   4992 e2fsck processes to print completion bars if it is given a -C option,
   4993 with the right thing happening if multiple filesystems are being
   4994 checked in parallel.
   4995 
   4996 Mke2fs now has better automatic hueristics to determine the filesystem
   4997 parameters to be used for a particular filesystem.  Added a new option
   4998 -T which allows the user to specify how the filesystem is to be used,
   4999 which helps mke2fs do a better job selecting the filesystem parameters.
   5000 
   5001 Mke2fs now creates revision 1 filesystems by default, and with the
   5002 sparse superblock feature enabled.  The sparse superblock feature is
   5003 not understood by Linux 2.0 kernels, so they will only allow read-only
   5004 mounts of filesystems with this sparse superblocks.
   5005 
   5006 Fix bug where if /dev/null couldn't be opened (should never happen),
   5007 e2fsck would hang in a tight loop.
   5008 
   5009 Make e2fsck handle the case where /lost+found isn't a directory.
   5010 
   5011 E2fsck now uses mallinfo if it exists to get accurate statistics about
   5012 its memory usage.
   5013 
   5014 Fix bug in e2fsck where it wouldn't check to see if a disconnected
   5015 inode had any problems before connecting it to /lost+found.
   5016 
   5017 Add check to e2fsck so it makes sure that total number of inodes in
   5018 the filesystem is a sane number.
   5019 
   5020 Fix fencepost error when clearing an the end of the block bitmap which
   5021 caused the last block in the bitmap not to get cleared.
   5022 
   5023 Cleaned up a number of messages in e2fsck:
   5024 	* The message "Group's #'s copy of the group descriptor..."
   5025 		was fixed so that the correct number would be displayed.
   5026 	* Added missing space in the "disk write-protected" error messsage
   5027 	* Cleaned up the error message printed when a non-interactive
   5028 		e2fsck needs to abort a check because the filesystem
   5029 		appears to be mounted.
   5030 
   5031 Added a new command-line utility, uuidgen, which will create and print
   5032 a UUID.
   5033 
   5034 Make debugfs's icheck command more robust by checking to make sure an
   5035 inode has valid blocks before interarting over the inode's blocks.
   5036 
   5037 UUID generation now uses a random-based scheme whenever possible to
   5038 prevent potential privacy problems.
   5039 
   5040 Man pages for all of the UUID functions in the lirbary were added.
   5041 
   5042 Fixed bug in fsck so it won't coredump if a filesystem not in
   5043 /etc/fstab is given to it.
   5044 
   5045 Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
   5046 that most of the other mount utilities understands.
   5047 
   5048 Mke2fs will make a filesystem even if it appears mounted if the force
   5049 option is given.
   5050 
   5051 Dumpe2fs has new command-line options which allow a filesystem expert
   5052 to specify the superblock and blocksize when opening a filesystem.
   5053 This is mainly useful when examining the remains of a toasted
   5054 filesystem.
   5055 
   5056 The badblocks program has been updated to display correctly on disks
   5057 with large block numbers.
   5058 
   5059 The badblocks program no longer gives spurious errors when errors
   5060 occur on non-block boundaries, which is common if the blocksize is
   5061 larger than 1k.
   5062 
   5063 Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
   5064 MKE2FS_SYNC environment variable is set.  This is to work around a VM
   5065 bug in the 2.0 kernel.  I've heard a report that a RAID user was able
   5066 to trigger it even using a 2.2 kernel, but hopefully it will not be
   5067 needed for most Linux 2.2 users.
   5068 
   5069 Fixed miscellaneous documentation and man pages.
   5070 
   5071 Programmer's notes:
   5072 -------------------
   5073 
   5074 Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
   5075 in e2fsck's pass1.c really should have been static.
   5076 
   5077 The return value of the uuid_compare() function was changed to make it
   5078 match with the convetions used by strcmp, memcmp, and Paul Leach's
   5079 UUID sample document.
   5080 
   5081 The "make depend" process has now been made more automated; it now
   5082 automatically word-wraps the dependencies, and only replaces source
   5083 Makefile.in if there has been a change in the dependencies.  Also, a
   5084 top-level "make depend" now recurses through all the subdirectories
   5085 automatically.
   5086 
   5087 The Makefile in .../util has been changed so that subst is built using
   5088 the native C compiler during a cross-compilation, since the subst
   5089 program is only used during the build process.  Also add an explicit
   5090 rule to build util/subst by cd'ing to the correct directory and
   5091 running Makefile.
   5092 
   5093 The man directories are defined in terms mandir, so that the configure
   5094 script can override the location of the manual pages.
   5095 
   5096 The config files have been updated to recognize new machine types for
   5097 both the i386 and alpha families.
   5098 
   5099 Fsck has been modified so that it will accurately create an
   5100 fsck_instance even when the noexecute flag is set.  This allows for
   5101 accurate debugging of the fsck pass structure.  Also, when the verbose
   5102 flag is given twice, fsck will print debugging information about when
   5103 fsck is waiting for jobs to finish.
   5104 
   5105 
   5106 E2fsprogs 1.14 (January 9, 1999)
   5107 ================================
   5108 
   5109 Fix the fstab parsing code so that it can handle blank lines and
   5110 comment characters.  Also, missing pass numbers need to be treated as
   5111 zero.
   5112 
   5113 Fixed a bug in e2fsck where under some circumstances (when e2fsck
   5114 needs to restart processing after fixing an egregious inconsistency)
   5115 it would try to access already freed memory.
   5116 
   5117 E2fsck now prints non-printable characters in directory entries and
   5118 pathnames using '^' and 'M-' notation.
   5119 
   5120 Fixed chattr so that it will ignore symbolic links when doing
   5121 recursive descent traversals.  For both chattr and lsattr, no longer
   5122 print the version string unless the -V option is given.
   5123 
   5124 Allow the system administrator to directly specify the number of
   5125 inodes desired in the filesystem, for some special cases where this is
   5126 necessary.
   5127 
   5128 Fix portability problems so that e2fsprogs can be compiled under Linux
   5129 1.2 systems and Solaris systems.
   5130 
   5131 Update the config.guess file with a more recent version that will
   5132 identify newer Linux platforms.
   5133 
   5134 Programmer's notes
   5135 ------------------
   5136 
   5137 Ext2fs_read_inode and ext2fs_write_inode will now return an error if
   5138 an inode number of zero is passed to them.
   5139 
   5140 E2fsprogs 1.13 (December 15, 1998)
   5141 ==================================
   5142 
   5143 Fixed a bug in debugfs where an error messages weren't getting printed
   5144 when the ext2 library routines to read inodes returned errors in the
   5145 stat, cmri and rm commands.
   5146 
   5147 Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
   5148 provided, it won't create an inode table smaller than the minimum
   5149 number of inodes required for a proper ext2 filesystem.
   5150 
   5151 Fsck now parses the /etc/fstab file directly (instead of using
   5152 getmntent()), so that it can distinguish between a missing pass number
   5153 field and pass number field of zero.  This caused problems for
   5154 diskless workstations where all of the filesystems in /etc/fstab have
   5155 an explicit pass number of zero, and fsck could not distinguish this
   5156 from a /etc/fstab file with missing pass numbers.
   5157 
   5158 E2fsck will create a /lost+found directory if there isn't one in the
   5159 filesystem, since it's safer to create the lost+found directory before
   5160 it's needed.
   5161 
   5162 Fixed e2fsck so that it would detect bogus immutable inodes which
   5163 happen to be sockets and FIFO files, and offer to clear them.
   5164 
   5165 If a filesystem has multiple reasons why it needs to be checked, and
   5166 one of the reasons is that it is uncleanly mounted, e2fsck will print
   5167 that as the reason why the filesystem is being checked.
   5168 
   5169 Cleaned up the output routines of mke2fs so that it doesn't overflow
   5170 an 80 column display when formating really big filesystems.
   5171 
   5172 Added a sanity check to e2fsck to make sure that file descriptors 0,
   5173 1, 2 are open before opening the hard disk.  This avoids a problem
   5174 where a broken program might exec e2fsck with those file descriptors
   5175 closed, which would cause disastrous results if the kernel returns a
   5176 file descriptor for the block device which is also used by FILE *
   5177 stdout.
   5178 
   5179 Fixed up the e2fsck progress reporting functions so that the values
   5180 reliably reach 100% at the completion of all of the e2fsck passes.
   5181 
   5182 Fixed minor documentation bugs in man pages and usage messages.
   5183 
   5184 Programmer's notes:
   5185 -------------------
   5186 
   5187 Fixed a number of lint warnings in the ext2fs library and potential
   5188 portability problems from other OS's header files that might define
   5189 CPP macros for names like "max" and "min".
   5190 
   5191 ext2fs_badblocks_list_add() has been made more efficient when it needs
   5192 to grow the bad blocks list.
   5193 
   5194 Fixed a bug in e2fsck which caused it to dereference a freed pointer
   5195 just before exiting.
   5196 
   5197 Fixed the substition process for generating the mk_cmds and compile_et
   5198 scripts so that they will work outside of the build tree.
   5199 
   5200 Add sanity check to e2fsck so that if an internal routine
   5201 (ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
   5202 and causing a core dump.  This should never happen, but...
   5203 
   5204 E2fsprogs 1.12 (July 9, 1998)
   5205 ==================================
   5206 
   5207 E2fsprogs now works with glibc (at least with the version shipped wtih
   5208 RedHat 5.0).  The ext2fs_llseek() function should now work even with
   5209 i386 ELF shared libraries and if llseek() is not present.  We also
   5210 explicitly do a configure test to see if (a) llseek is in libc, and
   5211 (b) if llseek is declared in the system header files.  (See standard
   5212 complaints about libc developers don't understand the concept of
   5213 compatibility with previous versions of libc.)
   5214 
   5215 The ext2fs library now writes out the block group number in each of
   5216 the superblock copies.  This makes it easier to automatically
   5217 determine the starting block group of the filesystem when the block
   5218 group information is trashed.
   5219 
   5220 Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
   5221 which means that e2fsprogs will ignore the high 8 bits of the
   5222 directory entry's name_len field, so that it can be used for other
   5223 purposes.
   5224 
   5225 Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
   5226 E2fsprogs will now support filesystems with 64-bit sized files.
   5227 
   5228 Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
   5229 
   5230 Added new program "e2label", contributed by Andries Brouwer.  E2label
   5231 provides an easy-to-use interface to modify the filesystem label.
   5232 
   5233 Fixed bug so that lsattr -v works instead of producing a core dump.
   5234 
   5235 Fixed a minor bug in mke2fs so that all groups with bad superblock
   5236 backup blocks are printed (not just the first one).
   5237 
   5238 Mke2fs will check the size of the device, and if the user specifies a
   5239 filesystem size larger than the apparent size of the device it will
   5240 print a warning message and ask if the user wants to proceed.
   5241 
   5242 E2fsck has a new option -C, which sends completion information to the
   5243 specified file descriptor.  For the most part, this is intended for
   5244 programs to use, although -C 0 will print a spinning character to the
   5245 stdout device, which may be useful for users who want to see something
   5246 happening while e2fsck goes about its business.
   5247 
   5248 Fixed a bug in e2fsck which could cause a core dump when it needs to
   5249 expand the /lost+found directory, and sometimes the bitmaps haven't
   5250 been merged in.  Also fixed a related bug where ext2fs_write_dir_block
   5251 was used to write out a non-directory block.  (Which would be bad on a
   5252 non-Intel platform with byte swapping going on.)
   5253 
   5254 Fixed bug in e2fsck where it would print a "programming error" message
   5255 instead of correctly identifying where a bad block was in used when
   5256 the bad block was in a non-primary superblock or block group
   5257 descriptor.  Also fixed a related bug when sparse superblocks are in
   5258 use and there is a bad block where a superblock or block group
   5259 descriptor would have been in a group that doesn't include a
   5260 superblock.
   5261 
   5262 Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
   5263 the block group descriptor table is corrupt, it was possible to try to
   5264 allocate a huge array, fail, and then abort e2fsck.
   5265 ext2fs_get_num_dirs() now sanity checks the block group descriptor,
   5266 and subsitutes reasonable values if the descriptors are obviously bogus.
   5267 
   5268 If e2fsck finds a device file which has the immutable flag set and the
   5269 i_blocks beyond the normal device number are non-zero, e2fsck will
   5270 offer to remove it, since it's probably caused by garbage in the inode
   5271 table.
   5272 
   5273 When opening a filesystem, e2fsck specially checks for the EROFS error
   5274 code, and prints a specific error message to the user which is more
   5275 user friendly.
   5276 
   5277 If the filesystem revision is too high, change the e2fsck to print
   5278 that this is either because e2fsck is out of date, or because the
   5279 superblock is corrupt.  
   5280 
   5281 E2fsck now checks for directories that have duplicate '.' and '..'
   5282 entries, and fixes this corruption.
   5283 
   5284 E2fsck no longer forces a sync of the filesystem (with attendant sleep
   5285 calls) at all times.  The ext2fs_flush() function now performs a sync
   5286 only if it needed to write data blocks to disk.
   5287 
   5288 Fixed a minor bug in e2fsck's pass1b's file cloning function, where
   5289 certain errors would not be properly reported.
   5290 
   5291 Updated and expanded a few points in the man pages which users
   5292 complained wheren't explicit enough.
   5293 
   5294 Added special case byte-swapping code if compiling on the PowerPC, to
   5295 accomodate the strange big-endian variant of the ext2 filesystem that
   5296 was previously used on the PowerPC port.
   5297 
   5298 
   5299 Programmer's notes:
   5300 -------------------
   5301 
   5302 Removed C++ keywords from the ext2fs libraries so that it could be
   5303 compiled with C++.
   5304 
   5305 E2fsck's internal organization has now been massively reorganized so
   5306 that pass*.c don't have any printf statements.  Instead, all problems
   5307 are reported through the fix_problem() abstraction interface.  E2fsck
   5308 has also been revamped so that it can be called as a library from a
   5309 application.
   5310 
   5311 Added new fileio primitives in libext2fs for reading and writing
   5312 files on an unmounted ext2 filesystem.  This interface is now used by
   5313 debugfs.
   5314 
   5315 Added a new libext2fs function for mapping logical block numbers of
   5316 a file to a physical block number.
   5317 
   5318 Added a new libext2fs function, ext2fs_alloc_block(), which allocates
   5319 a block, zeros it, and updates the filesystem accounting records
   5320 appropriately.
   5321 
   5322 Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
   5323 sets the padding of the bitmap to be all one's.  Used by e2fsck pass 5.
   5324 
   5325 The libext2fs functions now use a set of memory allocation wrapper
   5326 functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
   5327 instead of malloc, free, and resize.  This makes it easier for us to
   5328 be ported to strange environments where malloc, et. al. aren't
   5329 necessarily available.
   5330 
   5331 Change the libext2fs fucntion to return ext2-specific error codes
   5332 (EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
   5333 and depending on the existence of system error codes (such as EEXIST
   5334 and ENOENT).
   5335 
   5336 Renamed io.h to ext2_io.h to avoid collision with other OS's header
   5337 files.
   5338 
   5339 Add protection against ext2_io.h and ext2fs.h being included multiple
   5340 times.
   5341 
   5342 The types used for memory lengths, etc. have been made more portable.
   5343 In generla, the code has been made 16-bit safe.  Added Mark
   5344 Habersack's contributed DOS disk i/o routines.
   5345 
   5346 Miscellaneous portability fixes, including not depending on char's
   5347 being signed.
   5348 
   5349 The io_channel structure has a new element, app_data, which is
   5350 initialized by the ext2fs routines to contain a copy of the filesystem
   5351 handle.
   5352 
   5353 ext2fs_check_directory()'s callback function may now return the error
   5354 EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
   5355 really do the checking, despite the presence of the callback function.
   5356 
   5357 
   5358 E2fsprosg 1.11 (June 17, 1997)
   5359 ==============================
   5360 
   5361 Fixed e2fsck to detect (previously ignored) conflicts between the
   5362 superblock or block group descriptors and block bitmaps, inode
   5363 bitmaps, and inode tables.
   5364 
   5365 Fixed bug in e2fsck so that when the message printed out when a block
   5366 or inode bitmap conflicts with other data, it has the correct group
   5367 number.
   5368 
   5369 Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
   5370 to badblocks.  This meant that not all of the filesystem was being
   5371 tested for bad blocks! 
   5372 
   5373 Fixed an array boundary overrun case which cropped up in
   5374 ext2fs_badblocks_list_test when a user tried running "mke2fs -c 
   5375 -b 4096".
   5376 
   5377 Adjusted the number of columns printed by mke2fs when displaying the
   5378 superblock backups to avoid running over 80 columns when making a
   5379 really big filesystem.
   5380 
   5381 Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
   5382 dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
   5383 fixes), thanks to some suggestions from Bill Hawes (whawes (a] star.net).
   5384 
   5385 Programmer's notes:
   5386 -------------------
   5387 
   5388 Fixed install rule in lib/ss so that ss_err.h is actually getting
   5389 installed.
   5390 
   5391 Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
   5392 bassed back to the caller.
   5393 
   5394 Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
   5395 setting the current inode number (which meant this function wasn't
   5396 working at all).
   5397 
   5398 Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
   5399 blocks in the bitmap when increasing the size of the bitmap.
   5400 
   5401 Changed the initial number of blocks allocated by ext2fs_init_dblist()
   5402 to be more realistic.
   5403 
   5404 Added a new function ext2fs_allocate_group_table, which sets up the
   5405 group descriptor information (and allocates inode and block bitmaps,
   5406 and inode tables for a particular group).  The function was created by
   5407 factoring out code form ext2fs_allocate_tables().
   5408 
   5409 Added a new function ext2fs_move_blocks which takes a bitmap of the
   5410 blocks to be moved, and moves them to another location on the
   5411 boardboard.
   5412 
   5413 Make the unix_io channel's io_channel_flush implementation calls sync()
   5414 to to flush the kernel buffers to disk.
   5415 
   5416 Added a new function ext2fs_dblist_count returns the number of
   5417 directory blocks in dblist.
   5418 
   5419 
   5420 E2fsprogs 1.10 (April 24, 1997)
   5421 ===============================
   5422 
   5423 Mke2fs once again defaults to creating revision #0 filesystems, since
   5424 people were complaining about breaking compatibility with 1.2 kernels.
   5425 Warning messages were added to the mke2fs and tune2fs man pages that
   5426 the sparse superblock option isn't supported by most kernels yet (1.2
   5427 and 2.0 both don't support parse superblocks.)
   5428 
   5429 Added new flag to mke2fs, -R <raid options>, which allows the user to
   5430 tell mke2fs about the RAID configuration of the filesystem.  Currently
   5431 the only supported raid option is "stride" which specifies the width
   5432 of the RAID stripe.
   5433 
   5434 Fixed bug in e2fsck where pass1b would bomb out if there were any
   5435 blocks marked bad in the inode table.
   5436 
   5437 Fixed rare bug in mke2fs where if the user had a very unlucky number
   5438 of blocks in a filesystem (probability less than .002) the resulting
   5439 filesystem would be corrupt in the last block group.
   5440 
   5441 Fixed bug where if e2fsck tried to allocate a block to fix a
   5442 filesystem corruption problem and the filesystem had no free blocks,
   5443 ext2fs_new_block() would loop forever.
   5444 
   5445 The configure script now checks explicitly to see if "-static" works,
   5446 since that can't be assumed to be true --- RedHat doesn't install
   5447 libc-static by default.
   5448 
   5449 Fixed bug in libext2's block iterator functions where under some
   5450 cirmcustances, file with holes would cause the bcount parameter to the
   5451 callback function to be incorrect.  This bug didn't affect any of
   5452 e2fsprogs programs, but it was discovered by Paul Mackerras, the
   5453 author of the PPC boot loader.
   5454 
   5455 Removed use of static variables to store the inode cache in libext2fs.
   5456 This caused problems if more than one filesystem was accessed via
   5457 libext2fs (static variables in libraries are generally a bad idea).
   5458 Again, this didn't affect e2fsprogs programs, but it was discovered by
   5459 Paul Mackerras.
   5460 
   5461 Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
   5462 will compile cleanly with 1.2.13 kernels (even with a.out shared
   5463 libraries!)
   5464 
   5465 Programmer's notes:
   5466 -------------------
   5467 
   5468 Added new functions to duplicate an ext2 filesystem handle, and its
   5469 associated substructure.  New functions: ext2fs_dup_handle(),
   5470 ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
   5471 Other structures, such as the io_channel and the inode_cache, now have
   5472 a ref count so that they only get freed when they are no longer used
   5473 by any filesystem handle.  (These functions were added as part of the
   5474 development effort for an ext2 resizer).
   5475 
   5476 E2fsprogs 1.09 (April 14, 1997)
   5477 ===============================
   5478 
   5479 Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
   5480 accidentally introduced in the 1.08 release.  The overhead calculation
   5481 was accidentally removed, which caused ext2fs_initialize() to not
   5482 notice when the filesystem size needed to be adjusted down because
   5483 there wasn't enough space in the last block group.
   5484 
   5485 Fixed bug in version parsing library routine; it was always parsing
   5486 the library version string, instead of using the passed-in string.
   5487 
   5488 Clarified chattr man page.
   5489 
   5490 E2fsprogs 1.08 (April 10, 1997)
   5491 ===============================
   5492 
   5493 E2fsck 1.07 was very slow when checking very large filesystems with a
   5494 lot of files that had hard links (i.e., news spools).  This was fixed
   5495 by seriously revamping the icount abstraction.  Added a formal test
   5496 suite for the icount abstraction.
   5497 
   5498 Debugfs now has a "-l" option to the "ls" command, which lists the
   5499 inode number, permissions, owner, group, size, and name of the files
   5500 in the directory.
   5501 
   5502 Fix a bug in e2fsck where when a directory had its blocks moved to
   5503 another location during the pass 1b processing, the directory block
   5504 list wasn't updated, so pass 2 wouldn't check (and correct) the
   5505 correct directory block.
   5506 
   5507 E2fsck will now treat inodes which contain blocks which are claimed by
   5508 the filesystem metadata by treating them as multiply claimed blocks.
   5509 This way, the data in those blocks can be copied to a new block during
   5510 the pass 1b--1d processing.
   5511 
   5512 E2fsck will attempt to determine the correct superblock number and
   5513 display it in the diagnostic and warning messages if possible.
   5514 
   5515 Add support for a new (incompatible) feature, "sparse_super".  This
   5516 feature reduces the number of blocks which contain copies of backup
   5517 superblocks and block group descriptors.  (It is only an incompatible
   5518 feature because of a bug in ext2_free_blocks.)  mke2fs and tune2fs now
   5519 support a new -s option; e2fsck will recognize filesystems built with
   5520 this feature turned on.
   5521 
   5522 E2fsck now checks the library to make sure is the correct version,
   5523 using new library functions.  (This helps to diagnose incorrectly
   5524 installed e2fsprogs distributions.)
   5525 
   5526 Dumpe2fs now prints more information; its now prints the the
   5527 filesystem revision number, the filesystem sparse_super feature (if
   5528 present), the block ranges for each block group, and the offset from
   5529 the beginning of the block group.
   5530 
   5531 Mke2fs now distributes the inode and block bitmap blok so that the
   5532 won't be concentrated in one or two disks in RAID/striping setups.
   5533 Also, if the user chooses a 2k or 4k block group, mke2fs will try to
   5534 choose the largest blocks per group that be chosen.  (For 2k blocks,
   5535 you can have up to 16384 blocks/group; for 4k blocks, you can have up
   5536 to 32768 blocks/group.)  Previously mke2fs would not allow
   5537 specification of more than 8192 blocks per group, even if you were
   5538 using a 2k or 4k block group.
   5539 
   5540 Programmer's notes:
   5541 -------------------
   5542 
   5543 Added a new function ext2fs_create_icount2() which takes a "hint"
   5544 argument.  This hint argument presets the icount array with the list
   5545 of inodes which actually need to be in the icount array.  This really
   5546 helps to speed up e2fsck.
   5547 
   5548 Added a new function ext2fs_icount_validate() which checks the rep
   5549 invariant for the icount structure.  This is used mostly for testing.
   5550 
   5551 The error mesasage given when a bad inode number is passed to
   5552 test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
   5553 EXT2FS_UNMARK_ERROR).
   5554 
   5555 Added a new function ext2fs_set_dir_block which sets the block of a
   5556 dblist entry, given the directory inode and blockcnt.
   5557 
   5558 Added a new function ext2fs_get_library_version() which returns the
   5559 current library version, and ext2fs_parse_version_string() which
   5560 returns a version number based on a e2fsprogs version string.
   5561 
   5562 The icount functions will return EINVAL if the passed in inode number
   5563 is out of bounds.
   5564 
   5565 E2fsprogs 1.07 (March 9, 1997)
   5566 ==============================
   5567 
   5568 E2fsck is now uses much less memory when checking really large
   5569 filesystems (or rather, filesystems with a large number of inodes).
   5570 Previously a filesystem with 1 million inodes required 4 megabytes of
   5571 memory to store inode count statistics; that storage requirement has
   5572 now been reduced to roughly half a megabyte.
   5573 
   5574 E2fsck can now properly deal with bad blocks appearing inside the
   5575 inode table.  Instead of trying to relocate the inode table (which
   5576 often failed because there wasn't enough space), the inodes in the bad
   5577 block are marked as in use.
   5578 
   5579 E2fsck will automatically try to use the backup superblocks if the
   5580 primary superblocks have a bad magic number or have missing meta-data
   5581 blocks (or meta-data blocks which are out of range).
   5582 
   5583 E2fsck's pass 3 has been made more efficient; most noticeable on
   5584 filesystems with a very large number of directories.
   5585 
   5586 Completely revamped e2fsck's system of printing problem reports.  It
   5587 is now table driven, to make them more easily customizeable and
   5588 extendable.  Error messages which can be printed out during preen mode
   5589 are now one line long.
   5590 
   5591 Fixed e2fsck's filesystem swapping code so that it won't try to swap
   5592 fast symbolic links or deleted files.
   5593 
   5594 Fixed e2fsck core dumping when fixing a filesystem which has no
   5595 directories (not even a root directory).
   5596 
   5597 Added a check to e2fsck to make sure that the length of every
   5598 directory entry is a multiple of 4 (since the kernel complains if it
   5599 isn't).
   5600 
   5601 Added a check to e2fsck to make sure that a directory entry isn't a
   5602 link to the root directory, since that isn't allowed.
   5603 
   5604 Added a check to e2fsk to now make sure the '.' and '..' directory
   5605 entries are null terminated, since the 2.0 kernel requires it.
   5606 
   5607 Added check to write_bitmaps() to make sure the superblock doesn't get
   5608 trashed if the inode or block bitmap is marked as being block zero.
   5609 
   5610 Added checking of the new feature set fields in the superblock, to
   5611 avoid dealing with new filesystem features that this package wasn't
   5612 set up to handle.
   5613 
   5614 Fixed a fencepost error in ext2fs_new_block() which would occasionally
   5615 try to allocate a block beyond the end of a filesystem.
   5616 
   5617 When the UUID library picks a random IEEE 802 address (because it
   5618 can't find one from a network card), it sets the multicast bit, to
   5619 avoid conflicting with a legitimate IEEE 802 address.
   5620 
   5621 Mke2fs now sets the root directory's owner to be the real uid of the
   5622 user running mke2fs.  If the real uid is non-zero, it also sets
   5623 the group ownership of the root directory to be the real group-id of
   5624 the user running mke2fs.
   5625 
   5626 Mke2fs now has more intelligent error checking when it is given a
   5627 non-existent device.
   5628 
   5629 When badblocks is given the -vv option, it now updates the block that
   5630 it is currently testing on every block.
   5631 
   5632 Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
   5633 currently correctly if PATH wasn't already set.
   5634 
   5635 Shared libraries now built with dependencies.  This allows the shared
   5636 library files to be used with dlopen(); it also makes the transition
   5637 to libc 6 easier, since ld.so can tell which libc a particular shared
   5638 library expects to use.
   5639 
   5640 Programmer's notes:
   5641 -------------------
   5642 
   5643 Added new abstraction (defined in dblist.c) for maintaining a list of
   5644 blocks which belongs to directories.  This is used in e2fsck and other
   5645 programs which need to iterate over all directories.
   5646 
   5647 Added new functions which test to see if a contiguous range of blocks
   5648 (or inodes) are available.  (ext2fs_*_bitmap_range).
   5649 
   5650 Added new function (ext2_inode_has_valid_blocks) which returns true if
   5651 an inode has valid blocks.  (moved from e2fsck code).
   5652 
   5653 Added new function (ext2fs_allocate_tables) which allocates the
   5654 meta-data blocks as part of initializing a filesystem.  (moved from
   5655 mke2fs code).
   5656 
   5657 Added a new I/O manager for testing purposes.  It will either allow a
   5658 program to intercept I/O requests, or print debugging messages to
   5659 trace the activity of a program using the I/O manager.
   5660 
   5661 The badblocks_list functions now store the bad blocks in a sorted
   5662 order, and use a binary search to speed up badblocks_list_test.
   5663 
   5664 The inode scan function ext2fs_get_next_inode() may now return a soft
   5665 error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
   5666 those cases where part of an inode table is missing or there is a bad
   5667 block in the inode table.  
   5668 
   5669 Added a new function (ext2fs_block_iterate2) which adds new arguments to
   5670 the callback function to return a pointer (block and offset) to the
   5671 reference of the block.
   5672 
   5673 Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
   5674 application to jump to a particular block group while doing an inode
   5675 scan.
   5676 
   5677 The badblocks list functions were renamed from badblocks_* to
   5678 ext2fs_badblocks_*.  Backwards compatibility functions are available
   5679 for now, but programs should be modified to use the new interface.
   5680 
   5681 Some of the library functions were reorganized into separate files to
   5682 reduce the size of some programs which statically link against the
   5683 ext2 library.
   5684 
   5685 Put in some miscellaneous fixes for the Alpha platform.
   5686 
   5687 
   5688 E2fsprogs 1.06 (October 7, 1996)
   5689 ================================
   5690 
   5691 Fixed serious bug in e2fsck: if the block descriptors are bad, don't
   5692 smash the backup copies in ext2fs_close().  (The problem was that when
   5693 e2fsck -p discovered the problem, while it was closing the filesystem
   5694 and exiting, it was also blowing away the backup superblocks on the
   5695 disk, which was less than friendly.)  We now make it the case that we
   5696 only write out the backup superblock and the back block descriptors if
   5697 the filesystem is completely free from problems.
   5698 
   5699 Fixed a bug in block_interate in the lib/ext2fs library which caused
   5700 e2fsck to fail on GNU Hurd-created filesystems.
   5701 
   5702 Add support for Linux/FT's bootloader, which actually uses
   5703 EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
   5704 to clear the inode.
   5705 
   5706 Add support for the "A" (no atime update) attribute.  (Note: this
   5707 attribute is not yet in production kernels.)
   5708 
   5709 The test suite is not automatically run when doing a "make all" from
   5710 the top level directory.  Users should manually run "make check" if
   5711 they wish to run the test suite.
   5712 
   5713 Upon a preenhalt(), make the printed message more explicit that
   5714 running e2fsck "MANAULLY" means without the -p or -a options.
   5715 
   5716 In e2fsck, if a disconnected inode is zero-length, offer to clear it
   5717 instead of offering to connect it to lost+found.
   5718 
   5719 In e2fsck, if a filesystem was just unmounted uncleanly, and needs
   5720 e2fsck to be run over it, change e2fsck to explicitly display this
   5721 fact.
   5722 
   5723 For dumpe2fs and e2fsck, cause the -V option to print out which
   5724 version of the ext2fs library is actually getting used.  (This will
   5725 help detect mismatches of using a 1.06 utility with a 1.05 library,
   5726 etc.)
   5727 
   5728 Programmers' notes:
   5729 -------------------
   5730 
   5731 EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
   5732 the naming convention.
   5733 
   5734 In ext2fs_initialize(), make sure the description for the inode bitmap
   5735 is correctly initialize.
   5736 
   5737 Fixed minor type typo in ext2fs_allocate_generic_bitmap();
   5738 
   5739 E2fsprogs 1.05 (September 7, 1996)
   5740 ==================================
   5741 
   5742 Add support for new fields in the ext2 superblock --- volume name,
   5743 volume UUID, and last mounted field.  Dumpe2fs displays these fields,
   5744 tune2fs and mke2fs allows you to set them.  E2fsck will automatically
   5745 generate a UUID for those volumes that don't have them.  
   5746 
   5747 Put in support for e2fsck to recognize HURD specific ext2 features ---
   5748 most notably, the translator block.  The e2fsprogs tools will now use
   5749 the creator_os field in the superblock to correctly handle different
   5750 OS-specific variants of the ext2 filesystem.
   5751 
   5752 E2fsck now fixes inodes which have a the deletion time set, but which
   5753 have a non-zero i_link_count field by offering to clear the deletion
   5754 time.  Previously e2fsck assumed that the inode was deleted (per 0.3c
   5755 ext2 kernel behavior) and offered to unlink the file.
   5756 
   5757 If e2fsck sets the clean bit, but nothing else, set the exit code
   5758 FSCK_NONDESTRUCT.  After all, e2fsck did fix a filesystem error --- it
   5759 set the filesystem valid bit when it was previously cleared.  :-) This
   5760 was needed to make the HURD fsck driver happy.
   5761 
   5762 If the  user  refuses to attach an  unattached  inode, e2fsck  will no
   5763 longer set the inode's link count.  Otherwise, the  inode would end up
   5764 getting marked as unused, which might cause loss of data later.
   5765 
   5766 Make the message issued by e2fsck when the superblock is corrupt less
   5767 confusing for users.  It now mentions that another reason for the
   5768 "corrupt superblock" message might be that the partition might not be
   5769 an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
   5770 
   5771 Make the libext2 library more robuest so that e2fsck won't coredump on
   5772 an illegal superblock where the blocksize is zero.  (f_crashdisk is
   5773 the test case).
   5774 
   5775 By default, create filesystems where the default checkinterval is 6
   5776 months (180 days).  Linux servers can be robust enough that 20 reboots
   5777 can be a long, long time.
   5778 
   5779 Added configure flag --enable-old-bitops, which forces the bitops to
   5780 use the old (native) bitmask operations.  By default on the sparc
   5781 platform, the standard ext2 bit ordering is now used.
   5782 
   5783 Added a new feature to e2fsck to byte-swap filesystems; this can be
   5784 used to convert old m68k filesystems to use the standard byte-order
   5785 storage for the superblock, inodes, and directory blocks.  This
   5786 function is invoked by using the '-s' option to e2fsck.
   5787 
   5788 Debugfs's "dump" command has been enhanced so that it writes out the
   5789 exact size of the file so that the nulls at the end of the file are
   5790 eliminated.  The command also accept a new "-p" option which will
   5791 attempt preserve to preserve the ownernship, permissions, and
   5792 file modification/access times.
   5793 
   5794 Debugfs has two new options, -f and -R.  The -R option allows the user
   5795 to execute a single debugfs command from the command line.  The -f
   5796 option allows the user to specify a "command file" containing debugfs
   5797 commands which will get executed.
   5798 
   5799 Dumpe2fs now pretty prints the check interval, instead of just
   5800 printing the check interval as a number of seconds.
   5801 
   5802 Fix bugs in debugfs: the params command when no filesystem is opened
   5803 no longer causes a core dump.  It is now possible to unlink a file
   5804 when a pathame containing a '/' is specified.
   5805 
   5806 Tune2fs has a new -C option which sets the number of times the
   5807 filesystem has been mounted.
   5808 
   5809 Fix the chattr '-v' option so that it actually works.  Chattr was
   5810 being buggy about the -v option parsing.
   5811 
   5812 Programmers' notes:
   5813 -------------------
   5814 
   5815 The directory lib/uuid contains a set of library routines to generate
   5816 DCE compatible UUIDs.  
   5817 
   5818 Extended ext2fs_namei() to handle symbolic links.  Added new function
   5819 ext2fs_nami_follow() which will follow last symbolic link in the case
   5820 where the pathname points to a sym link.
   5821 
   5822 The ext2fs_block_iterate function will now return the HURD translator
   5823 block, if present.  The new flag BLOCK_FLAG_DATA_ONLY will cause the
   5824 iterator to return data blocks only.  The ext2fs.h file now defines
   5825 constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
   5826 BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
   5827 count field of the iterator callback function.
   5828 
   5829 The test script driver now takes an optional second argument, which is
   5830 the test case to be run.  This allows you to run a test case without
   5831 needing to run the entire test suite.
   5832 
   5833 On Linux ELF systems, install the .so files in the correct places
   5834 (/usr/lib).  The .so files must be stored in the same directory as the
   5835 .a files.
   5836 
   5837 Fixed miscellaneous HURD compilation issues with header file being
   5838 included in the right order.
   5839 
   5840 Fixed debugfs so that it resets optind to zero, not one, since setting
   5841 optind to zero is more correct.
   5842 
   5843 
   5844 E2fsprogs 1.04 (May 16, 1996)
   5845 =============================
   5846 
   5847 First "official" (1.03 was a limited release only) to support building
   5848 e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
   5849 kernels).
   5850 
   5851 This package includes a RPM specs file, that it can be built using the
   5852 RedHat Package Manager.
   5853 
   5854 E2fsck now prints a hint that if there are lots of incorrectly located
   5855 inode bitmaps, block bitmaps, and inode table blocks, the user might
   5856 want to try using e2fsck -b 8193 first, to see if that fares any
   5857 better.
   5858 
   5859 For ext2 filesystem written with the hurd, debugfs will now print out
   5860 the translator field when printing an inode structure.
   5861 
   5862 Lots of miscellaneous linking/installation cleanups:
   5863 
   5864   Libraries are now linked using a relative pathname, instead of
   5865   relying on -L working correct.  It doesn't, in many cases, including
   5866   current versions of GNU ld.  This guarantees that the build tree is
   5867   linking with the right libraries, instead of the ones installed in
   5868   /usr/lib.
   5869 
   5870   Header files, man pages, and the et/ss shell scripts are now
   5871   generated using a custom substitution script, instead of relying on
   5872   the configure script.  This prevents needless recompilation of
   5873   files; in addition, the custom substitution script is much faster.
   5874 
   5875   e2fsck may now be linked dynamically, by using the
   5876   --enable-dynamic-e2fsck flag to configure.  This is not recommended,
   5877   since it increases e2fsck's dependence on other files, but some
   5878   people need to save disk space, and other critical programs on their
   5879   systems were being linked dynamically anyway.
   5880 
   5881   Programs such as fsck which didn't need to be linked against
   5882   libext2fs (or mke2fs which didn't need to be linked against libe2p)
   5883   only link against libraries they actually need.  Otherwise, those
   5884   programs would require the presense of libraries that otherwise
   5885   could be removed from a rescuse diskette.
   5886 
   5887   The ss include files are now installed correctly so they can
   5888   actually be used by another package.
   5889 
   5890   If the profiling libraries are built, they are now installed on a
   5891   "make install-libs".

   5894 E2fsprogs 1.03 (March 27, 1996)
   5895 ===============================
   5896 
   5897 Change the m68k bit numbering for bitmasks to match the bit numbering
   5898 used by all other ext2 implementations.  (This change was requested by
   5899 the m68k kernel development team.)
   5900 
   5901 Support (in-development) filesystem format revision which supports
   5902 (among other things) dynamically sized inodes.
   5903 
   5904 Fixed a bug in the ext2 library so that an intelligent error is
   5905 returned if mke2fs is run with a ridiculously small number of blocks
   5906 for a partition.
   5907 
   5908 Fixed a bug in the ext2 library which required that the device be
   5909 openable in read/write mode in order to determine its size.  This
   5910 caused e2fsck -n to require read/write access when it was not
   5911 previously necessary.
   5912 
   5913 Fixed a bug in e2fsck which casued it to occasionally fail the test
   5914 suite depending on which version of the floating point library it was
   5915 using.
   5916 
   5917 Fixed a bug in e2fsck so that it now halts with a fatal error when
   5918 certain superblock consistency checks fail.  Previously it continued
   5919 running e2fsck, with some potential confusing/damaging consequences.
   5920 
   5921 Added new flag to fsck which allows the root to be checked in parallel
   5922 with other filesytems.  This is not the safest thing in the world to
   5923 do, but some system administrators really wanted it.
   5924 
   5925 Fixed -Wall flames in lib/ss.
   5926 
   5927 
   5928 E2fsprogs 1.02 (January 16, 1996)
   5929 =================================
   5930 
   5931 Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
   5932 
   5933 Change e2fsck to print statistics of how many non-contiguous files are
   5934 on the system.  Note that a file which is larger than 8k blocks, it is
   5935 guaranteed to be non-contiguous.
   5936 
   5937 In mke2fs, print a warning message if a user tries to format a whole
   5938 disk (/dev/hda versus /dev/hda1).  If a user really wants to format a
   5939 whole disk, the -F (force) option forces mke2fs to format a whole disk
   5940 as a filesytem.
   5941 
   5942 Fix a bug in fsck where in some cases it might start checking
   5943 partitions in the next pass before it finishes checking partitions in
   5944 the current pass.  This still won't cause two partitions on the same
   5945 disk will be checked, so it's rarely a problem in real life.
   5946 
   5947 Patch lsattr so that it won't hang when checking a named pipe.
   5948 
   5949 Minor compilation fixes:
   5950 	* Fix the order of libraries that were linked in debugfs.
   5951 	* Allow the sources to be compiled with -ansi turned on.
