Package: cpio Version: 2.6-11 Severity: important
I am seeing certain archives created by cpio -o -H ustar come out unextractable by either tar or cpio. It appears to be data dependent. The ones that work, work reliably, and the ones that fail, fail repeatably in the same spot. Backing up the /bin directory of a current Debian/i386 system seems to be a good source of failures... devastator:~# cd / devastator:/# find bin -true -print | cpio -o -H ustar > /tmp/check-bin.tar 6937 blocks devastator:/# cd /tmp/root-restore devastator:/tmp/root-restore# cpio -i -H ustar < ../check-bin.tar cpio: premature end of file devastator:/tmp/root-restore# ls bin devastator:/tmp/root-restore# ls bin ae devastator:/tmp/root-restore# rm -r bin devastator:/tmp/root-restore# tar -xvf ../check-bin.tar bin/ bin/ae bin/dd bin/cp bin/df bin/ed bin/ln bin/ls bin/nc bin/mt bin/mv bin/ps bin/rm bin/sh bin/su bin/vi bin/cat bin/csh bin/dir bin/pwd bin/sed bin/tar bin/bash bin/arch bin/date bin/cpio bin/echo bin/grep bin/gzip bin/kill bin/more bin/ping bin/tcsh bin/stty bin/sync bin/true bin/vdir bin/zcat bin/zcat tar: Skipping to next header tar: Error exit delayed from previous errors devastator:/tmp/root-restore# It's interesting that tar shows that it is attempting to restore bin/zcat twice, right at the point it errors out. Perhaps that's a clue as to the nature of the error. I have verified that this bug also exists in cpio 2.6-10. I haven't yet checked any other versions. I have saved off my check-bin.tar, and will provide it on request. I just didn't want to attach it with the bug report because even bzip2'ed, it's still > 1MB. -- System Information: Debian Release: testing/unstable APT prefers unstable APT policy: (500, 'unstable'), (500, 'stable') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.4.29 Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968) Versions of packages cpio depends on: ii libc6 2.3.6-4 GNU C Library: Shared libraries an cpio recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
