SQUASHFS/squashfs-tools-4.4/ACKNOWLEDGEMENTS

   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@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.

  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 David Fox (Lindows) noticed that the exit codes returned by Mksquashfs were
 112 wrong.  He also noticed that a lot of time was spent in the duplicate scan
 113 routine.
 114
 115 Cameron Rich complained that Squashfs did not support FIFOs or sockets.
 116
 117 Steve Chadsey and Thomas Weissmuller noticed that files larger than the
 118 available memory could not be compressed by Mksquashfs.
 119
 120 "Ptwahyu" and "Hoan" (I have no full names and I don't like giving people's
 121 email addresses), noticed that Mksquashfs 1.3 SEGV'd occasionally.  Even though
 122 I had already noticed this bug, it is useful to be informed by other people.
 123
 124 Don Elwell, Murray Jensen and Cameron Rich, have all sent in patches.  Thanks,
 125 I have not had time to do anything about them yet...
 126
 127 Drew Scott Daniels has been a good advocate for Squashfs.
 128
 129 Erik Andersen has made some nice suggestions, unfortunately, I have
 130 not had time to implement anything.
 131
 132 Artemiy I. Pavlov has written a useful LDP mini-howto for Squashfs
 133 (http://linuxdoc.artemio.net/squashfs).
 134
 135 Yves Combe reported the Apple G5 bug, when using Squashfs for
 136 his PPC Knoppix-mib livecd project.
 137
 138 Jaco Greeff (mklivecd project, and maintainer of the Mandrake
 139 squashfs-tools package) suggested the new mksquashfs -ef option, and the
 140 standalone build for mksquashfs.
 141
 142 Mike Schaudies made a donation.
 143
 144 Arkadiusz Patyk from the Polish Linux Distribution reported that Squashfs
 145 didn't work on amd64 machines. He gave me an account on a PLD amd64 machine
 146 which allowed myself to track down these bugs.
 147
 148 Miles Roper, Peter Kjellerstedt and Willy Tarreau reported that release 2.1 did
 149 not compile with gcc < 3.x.
 150
 151 Marcel J.E. Mol reported lack of kernel memory issues when using Squashfs
 152 on small memory embedded systems.  This prompted the addition of the embedded
 153 system kernel configuration options.
 154
 155 Era Scarecrow noticed that Mksquashfs had not been updated to reflect that
 156 smaller than 4K blocks are no longer supported.
 157
 158 Kenichi Shima reported the Kconfig file had not been updated to 2.2.
