Package: rsync
Version: 3.0.3-2
Severity: normal
I am sorry for this quite generic subject, but this is it: rsync segfaults
while rsyncing.
Situation:
hild(laptop) skuld (workstation, segfaulting receiver)
/ (/dev/hda1) --------------> /mnt/backup
(/mnt/mybook/backup/hild-backup.img ext3 via loop)
hild is running the rsync-daemon (as root) and skuld uses '/usr/bin/rsync
-aHAXxv --progress --delete-before --stats --numeric-ids hild::root/
/mnt/backup/hild' to backup the while /-filesystem from hild to an ext3 on a
loop-file.
After some rsyncing, one part of the receiving rsync segfaults, the other part
stays alive (see further down).
I recompiled it with debug,nostrip to gather the following backtrace.
It dies inside while rsyncing my cowbuilder chroot(), to my totally uneducated
eye (and brain) this looks like a problem with -X, because rsync is able to
complete the job while not using -X.
Kernel is configured with XATTR support:
CONFIG_EXT3_FS=y
CONFIG_EXT3_FS_XATTR=y
CONFIG_EXT3_FS_POSIX_ACL=y
CONFIG_EXT3_FS_SECURITY=y
but the mount of the target filesystem does not use it:
/mnt/mybook/backup/hild-backup.img on /mnt/backup type ext3 (rw,loop=/dev/loop0)
