1 E2fsprogs 1.44.0 (March 7, 2018) 2 ================================ 3 4 Updates/Fixes since v1.43.9: 5 6 UI and Features 7 --------------- 8 9 E2fsprogs now supports the large_dir (INCOMPAT_LARGEDIR) feature. This 10 feature allows larger directories to be created, both with directory 11 sizes over 2GB and and a maximum htree depth of 3 instead of the 12 current limit of 2. These features are needed in order to exceed 13 the currently limit of approximately 10M entries in a single 14 directory for 4KB blocksize (~100k for 1KB). 15 16 E2fsprogs now supports the ea_inode (INCOMPAT_EA_INODE) feature, which 17 stores large extended attributes in an external inode instead of a 18 single data block. This is backwards compatible with a Lustre file 19 system feature, but it has been extended to support deduplicating 20 extended attribute values which are used in multiple inodes. 21 22 The metadata_csum feature (RO_COMPAT_METADATA_CSUM) is now enabled by 23 default by mke2fs. 24 25 The resize2fs program will no longer complain about resizing bigalloc 26 file systems as being dangerous when doing an on-line resize (since this 27 is purely a kernel feature). 28 29 Debugfs's ls command will now print the high bits of the inode's mode 30 bits. 31 32 Fixes 33 ----- 34 35 Fixed some potential buffer overrun bugs in the blkid library and in the 36 fsck program. 37 38 There were some corner cases which tune2fs wouldn't correctly handle 39 when operating on a file system which was not cleanly mounted and thus 40 required running the journal because it could be modified. Tune2fs will 41 now run the journal before trying to change the superblock, and if the 42 file system needs to be checked after the journal has been replayed, it 43 will require it before proceeding. Also if the file system is busy (for 44 example, because it is in use by Lustre), but is not present in the 45 /proc/mounts or /etc/mtab, tune2fs will not try to replay the journal, 46 since this could do real damage if it the file system is being actively 47 modified by the kernel. 48 49 The libss library (used by debugfs) now supports the version 7 of the 50 libreadline shared library. 51 52 The e2freefrag program will use the GETFSMAP ioctl if it is available 53 and the file system is mounted, so that the free space statistics will 54 be more accurate. 55 56 The consistency checks for symlinks (especially for encrypted and inline 57 data file sytems) in e2fsck are now much more careful/stringent. Also 58 fixed a bug where creating a symlink using ext2fs_symlink() which was 59 exactly 60 bytes long when inline data was enabled would result in a 60 missing system.data xattr. 61 62 63 Performance, Internal Implementation, Development Support etc. 64 -------------------------------------------------------------- 65 66 Mke2fs now uses io_channel_flush() instead of sync() for the sync_kludge 67 feature. 68 69 E2fsprogs now uses i_size as the primary way of determining whether a 70 symlink is a fast symlink. 71 72 Fix various compiler and UBSAN warnings. 73 74 Long running test are now skipped with "make check" and only run when 75 "make fullcheck". The test runner will warn when potentially long 76 running tests are being run via "make check". 77 78 E2fsck is now much faster for bigalloc file systems when scanning 79 extents for bigalloc file systems.
