2013-02-27xz: fix incorrect XZ_BUF_ERRORLasse Collin
xz_dec_run() could incorrectly return XZ_BUF_ERROR if all of the following was true: - The caller knows how many bytes of output to expect and only provides that much output space. - When the last output bytes are decoded, the caller-provided input buffer ends right before the LZMA2 end of payload marker. So LZMA2 won't provide more output anymore, but it won't know it yet and thus won't return XZ_STREAM_END yet. - A BCJ filter is in use and it hasn't left any unfiltered bytes in the temp buffer. This can happen with any BCJ filter, but in practice it's more likely with filters other than the x86 BCJ. This fixes <https://bugzilla.redhat.com/show_bug.cgi?id=735408> where Squashfs thinks that a valid file system is corrupt. Thanks to Jindrich Novy for telling me that such a bug report exists, Phillip Lougher for providing excellent debug info, and other people on #fedora-ppc. This also fixes a similar bug in single-call mode where the uncompressed size of a XZ Block using BCJ + LZMA2 was 0 bytes and caller provided no output space. Many empty .xz files don't contain any Blocks and thus don't trigger this bug. This also tweaks a closely related detail: xz_dec_bcj_run() could call xz_dec_lzma2_run() to decode into temp buffer when it was known to be useless. This was harmless although it wasted a minuscule number of CPU cycles. Signed-off-by: Lasse Collin <lasse.collin@tukaani.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2013-02-27xz: fix decoding of LZMA2 streams having no uncompressed data.Lasse Collin
No .xz encoder creates files with empty LZMA2 streams, but such files would still be valid and decompressors must accept them. Note that empty .xz files are a different thing than empty LZMA2 streams. This bug didn't affect typical .xz files that had no uncompressed data.

2013-02-27mdev: improve $SEQ handling; improve debug loggingDenys Vlasenko
Sequential run of concurrent mdev's was too simplistic: they waited for /dev/mdev.seq to match. This could sometimes cause cumulative loss of time on the order of a second. Added SIGCHLD signaling from exiting mdev to all other mdev's. Added debugging required to see that code actually works as intended. Example of /dev/mdev.log (with "woken up" elevated from dbg lvl 3 to 2): mdev[1023]: first seq written ^^^^ seq, not pid mdev[1023]: 35.022395 ACTION:add SUBSYSTEM:module DEVNAME:(null) DEVPATH:/module/lib80211 mdev[1023]: rule matched, line -1 ^^^^^^^ means "default rule" mdev[1023]: 35.022676 exiting ^^^^^^^^^ second,usec timestamp mdev[1024]: 35.069691 ACTION:add SUBSYSTEM:vc DEVNAME:vcs9 DEVPATH:/devices/virtual/vc/vcs9 mdev[1024]: dev 7,9 mdev[1025]: 35.069889 waiting for '1024' mdev[1026]: 35.069946 waiting for '1024' mdev[1027]: 35.070151 waiting for '1024' mdev[1024]: rule matched, line -1 mdev[1024]: mknod vcs9 (7,9) 20660 0:0 mdev[1024]: 35.070346 exiting mdev[1025]: woken up mdev[1026]: woken up mdev[1025]: 35.071213 ACTION:add SUBSYSTEM:vc DEVNAME:vcsa9 DEVPATH:/devices/virtual/vc/vcsa9 ^^^^^^^^^ took only a millisecond to start running after prev mdev exited mdev[1025]: dev 7,137 mdev[1027]: woken up mdev[1025]: rule matched, line -1 mdev[1025]: mknod vcsa9 (7,137) 20660 0:0 mdev[1025]: 35.072109 exiting function old new delta mdev_main 849 1372 +523 curtime - 59 +59 dirAction 87 134 +47 static.ts - 8 +8 keywords 19 12 -7 make_device 2189 2119 -70 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

As suggested by Mike. No bloat-o-meter difference, but a bit nicer to look at. We cannot convert the call to log_to_shmem() as it checks for G.shbuf outside the function, and G.shbuf is only available when IPC support is enabled.
