1 ACKNOWLEDGEMENTS 2 3 Thanks to everyone who have downloaded Squashfs. I appreciate people 4 using it, and any feedback you have. 5 6 The following have provided useful feedback, which has guided 7 some of the extra features in squashfs. This is a randomly ordered 8 (roughly in chronological order) list, which is updated when 9 I remember... 10 11 Acknowledgements for Squashfs 4.3 12 --------------------------------- 13 14 Thanks to Bruno Wolff III and Andy Lutomirski for useful feedback 15 during the long development process of Squashfs 4.3. 16 17 Acknowledgements for Squashfs 4.2 18 --------------------------------- 19 20 Thanks to Lasse Collin (http://tukaani.org/xz/) for mainlining XZ 21 decompression support. 22 23 Acknowledgements for Squashfs 4.1 24 --------------------------------- 25 26 Thanks to Chan Jeong <chan.jeong (a] lge.com> and LG for the patches to support LZO 27 compression. 28 29 Acknowledgements for Squashfs 4.0 30 --------------------------------- 31 32 Thanks to Tim Bird and CELF (Consumer Electronics Linux Forum) for helping 33 fund mainstreaming of Squashfs into the 2.6.29 kernel and the 34 changes to the Squashfs tools to support the new 4.0 file system layout. 35 36 Acknowledgements for Squashfs-3.3 37 ------------------------------------ 38 39 Peter Korsgaard and others sent patches updating Squashfs to changes in the 40 VFS interface for 2.6.22/2.6.23/2.6.24-rc1. Peter also sent some small patches 41 for the Squashfs kernel code. 42 43 Vito Di Leo sent a patch extending Mksquashfs to support regex filters. 44 While his patched worked, it unfortunately made it easy to make Mksquashfs 45 perform unpredictably with poorly choosen regex expressions. It, however, 46 encouraged myself to add support for wildcard pattern matching and regex 47 filters in a different way. 48 49 Acknowledgements for Squashfs-3.2-r2 50 ------------------------------------ 51 52 Junjiro Okajima discovered a couple of SMP issues, thanks. 53 54 Junjiro Okajima and Tomas Matejicek have produced some good LZMA patches 55 for Squashfs. 56 57 Acknowledgements for Squashfs-3.2 58 --------------------------------- 59 60 Peter Korsgaard sent a patch updating Squashfs to changes in the VFS interface 61 in Linux 2.6.20. 62 63 Acknowledgements for Squashfs-3.1 64 --------------------------------- 65 66 Kenneth Duda and Ed Swierk of Arastra Inc. identified numerous bugs with 67 Squashfs, and provided patches which were the basis for some of the 68 fixes. In particular they identified the fragment rounding bug, the 69 NFS bug, the initrd bug, and helped identify the 4K stack overflow bug. 70 71 Scott James Remnant (Ubuntu) also identified the fragment rounding bug, 72 and he also provided a patch. 73 74 Ming Zhang identified the Lseek bug in Mksquashfs. His tests on the 75 performance of Mksquashfs on SMP systems encouraged the rewrite of 76 Mksquashfs. 77 78 Peter Korsgaard, Daniel Olivera and Zilvinas Valinskas noticed 79 Squashfs 3.0 didn't compile on Linux-2.6.18-rc[1-4] due to changes 80 in the Linux VFS interfaces, and provided patches. 81 82 Tomas Matejicek (SLAX) suggested the -force option on Unsquashfs, and noticed 83 Unsquashfs didn't return the correct exit status. 84 85 Yann Le Doare reported a kernel oops and provided a Qemu image that led 86 to the identification of the simultaneously accessing multiply mounted Squashfs 87 filesystems bug. 88 89 90 Older acknowledgements 91 ---------------------- 92 93 Mark Robson - pointed out early on that initrds didn't work 94 95 Adam Warner - pointed out that greater than 2GB filesystems didn't work. 96 97 John Sutton - raised the problem when archiving the entire filesystem 98 (/) there was no way to prevent /proc being archived. This prompted 99 exclude files. 100 101 Martin Mueller (LinuxTV) - noticed that the filesystem length in the 102 superblock doesn't match the output filesystem length. This is due to 103 padding to a 4K boundary. This prompted the addition of the -nopad option. 104 He also reported a problem where 32K block filesystems hung when used as 105 initrds. 106 107 Arkadiusz Patyk (Polish Linux Distribution - PLD) reported a problem where 32K 108 block filesystems hung when used as a root filesystem mounted as a loopback 109 device. 110 111 Joe Blow emailed me that I'd forgotten to put anything in the README about 112 mounting the squashfs filesystem. 113 114 David Fox (Lindows) noticed that the exit codes returned by Mksquashfs were 115 wrong. He also noticed that a lot of time was spent in the duplicate scan 116 routine. 117 118 Cameron Rich complained that Squashfs did not support FIFOs or sockets. 119 120 Steve Chadsey and Thomas Weissmuller noticed that files larger than the 121 available memory could not be compressed by Mksquashfs. 122 123 "Ptwahyu" and "Hoan" (I have no full names and I don't like giving people's 124 email addresses), noticed that Mksquashfs 1.3 SEGV'd occasionally. Even though 125 I had already noticed this bug, it is useful to be informed by other people. 126 127 Don Elwell, Murray Jensen and Cameron Rich, have all sent in patches. Thanks, 128 I have not had time to do anything about them yet... 129 130 Drew Scott Daniels has been a good advocate for Squashfs. 131 132 Erik Andersen has made some nice suggestions, unfortunately, I have 133 not had time to implement anything. 134 135 Artemiy I. Pavlov has written a useful LDP mini-howto for Squashfs 136 (http://linuxdoc.artemio.net/squashfs). 137 138 Yves Combe reported the Apple G5 bug, when using Squashfs for 139 his PPC Knoppix-mib livecd project. 140 141 Jaco Greeff (mklivecd project, and maintainer of the Mandrake 142 squashfs-tools package) suggested the new mksquashfs -ef option, and the 143 standalone build for mksquashfs. 144 145 Mike Schaudies made a donation. 146 147 Arkadiusz Patyk from the Polish Linux Distribution reported that Squashfs 148 didn't work on amd64 machines. He gave me an account on a PLD amd64 machine 149 which allowed myself to track down these bugs. 150 151 Miles Roper, Peter Kjellerstedt and Willy Tarreau reported that release 2.1 did 152 not compile with gcc < 3.x. 153 154 Marcel J.E. Mol reported lack of kernel memory issues when using Squashfs 155 on small memory embedded systems. This prompted the addition of the embedded 156 system kernel configuration options. 157 158 Era Scarecrow noticed that Mksquashfs had not been updated to reflect that 159 smaller than 4K blocks are no longer supported. 160 161 Kenichi Shima reported the Kconfig file had not been updated to 2.2. 162 163 Aaron Ten Clay made a donation! 164 165 Tomas Matejicek (SLAX) made a donation! 166
