ACKNOWLEDGEMENTS Thanks to everyone who have downloaded Squashfs. I appreciate people using it, and any feedback you have. The following have provided useful feedback, which has guided some of the extra features in squashfs. This is a randomly ordered (roughly in chronological order) list, which is updated when I remember... Acknowledgements for Squashfs 4.3 --------------------------------- Thanks to Bruno Wolff III and Andy Lutomirski for useful feedback during the long development process of Squashfs 4.3. Acknowledgements for Squashfs 4.2 --------------------------------- Thanks to Lasse Collin (http://tukaani.org/xz/) for mainlining XZ decompression support. Acknowledgements for Squashfs 4.1 --------------------------------- Thanks to Chan Jeong <chan.jeong@lge.com> and LG for the patches to support LZO compression. Acknowledgements for Squashfs 4.0 --------------------------------- Thanks to Tim Bird and CELF (Consumer Electronics Linux Forum) for helping fund mainstreaming of Squashfs into the 2.6.29 kernel and the changes to the Squashfs tools to support the new 4.0 file system layout. Acknowledgements for Squashfs-3.3 ------------------------------------ Peter Korsgaard and others sent patches updating Squashfs to changes in the VFS interface for 2.6.22/2.6.23/2.6.24-rc1. Peter also sent some small patches for the Squashfs kernel code. Vito Di Leo sent a patch extending Mksquashfs to support regex filters. While his patched worked, it unfortunately made it easy to make Mksquashfs perform unpredictably with poorly choosen regex expressions. It, however, encouraged myself to add support for wildcard pattern matching and regex filters in a different way. Acknowledgements for Squashfs-3.2-r2 ------------------------------------ Junjiro Okajima discovered a couple of SMP issues, thanks. Junjiro Okajima and Tomas Matejicek have produced some good LZMA patches for Squashfs. Acknowledgements for Squashfs-3.2 --------------------------------- Peter Korsgaard sent a patch updating Squashfs to changes in the VFS interface in Linux 2.6.20. Acknowledgements for Squashfs-3.1 --------------------------------- Kenneth Duda and Ed Swierk of Arastra Inc. identified numerous bugs with Squashfs, and provided patches which were the basis for some of the fixes. In particular they identified the fragment rounding bug, the NFS bug, the initrd bug, and helped identify the 4K stack overflow bug. Scott James Remnant (Ubuntu) also identified the fragment rounding bug, and he also provided a patch. Ming Zhang identified the Lseek bug in Mksquashfs. His tests on the performance of Mksquashfs on SMP systems encouraged the rewrite of Mksquashfs. Peter Korsgaard, Daniel Olivera and Zilvinas Valinskas noticed Squashfs 3.0 didn't compile on Linux-2.6.18-rc[1-4] due to changes in the Linux VFS interfaces, and provided patches. Tomas Matejicek (SLAX) suggested the -force option on Unsquashfs, and noticed Unsquashfs didn't return the correct exit status. Yann Le Doare reported a kernel oops and provided a Qemu image that led to the identification of the simultaneously accessing multiply mounted Squashfs filesystems bug. Older acknowledgements ---------------------- Mark Robson - pointed out early on that initrds didn't work Adam Warner - pointed out that greater than 2GB filesystems didn't work. John Sutton - raised the problem when archiving the entire filesystem (/) there was no way to prevent /proc being archived. This prompted exclude files. Martin Mueller (LinuxTV) - noticed that the filesystem length in the superblock doesn't match the output filesystem length. This is due to padding to a 4K boundary. This prompted the addition of the -nopad option. He also reported a problem where 32K block filesystems hung when used as initrds. Arkadiusz Patyk (Polish Linux Distribution - PLD) reported a problem where 32K block filesystems hung when used as a root filesystem mounted as a loopback device. Joe Blow emailed me that I'd forgotten to put anything in the README about mounting the squashfs filesystem. David Fox (Lindows) noticed that the exit codes returned by Mksquashfs were wrong. He also noticed that a lot of time was spent in the duplicate scan routine. Cameron Rich complained that Squashfs did not support FIFOs or sockets. Steve Chadsey and Thomas Weissmuller noticed that files larger than the available memory could not be compressed by Mksquashfs. "Ptwahyu" and "Hoan" (I have no full names and I don't like giving people's email addresses), noticed that Mksquashfs 1.3 SEGV'd occasionally. Even though I had already noticed this bug, it is useful to be informed by other people. Don Elwell, Murray Jensen and Cameron Rich, have all sent in patches. Thanks, I have not had time to do anything about them yet... Drew Scott Daniels has been a good advocate for Squashfs. Erik Andersen has made some nice suggestions, unfortunately, I have not had time to implement anything. Artemiy I. Pavlov has written a useful LDP mini-howto for Squashfs (http://linuxdoc.artemio.net/squashfs). Yves Combe reported the Apple G5 bug, when using Squashfs for his PPC Knoppix-mib livecd project. Jaco Greeff (mklivecd project, and maintainer of the Mandrake squashfs-tools package) suggested the new mksquashfs -ef option, and the standalone build for mksquashfs. Mike Schaudies made a donation. Arkadiusz Patyk from the Polish Linux Distribution reported that Squashfs didn't work on amd64 machines. He gave me an account on a PLD amd64 machine which allowed myself to track down these bugs. Miles Roper, Peter Kjellerstedt and Willy Tarreau reported that release 2.1 did not compile with gcc < 3.x. Marcel J.E. Mol reported lack of kernel memory issues when using Squashfs on small memory embedded systems. This prompted the addition of the embedded system kernel configuration options. Era Scarecrow noticed that Mksquashfs had not been updated to reflect that smaller than 4K blocks are no longer supported. Kenichi Shima reported the Kconfig file had not been updated to 2.2.
