Bug#493184: aufs: Deadlocks in the rename() call.
Package: aufs
Version: 0+20080719-1
Severity: serious
Tags: patch
Hi jak,
as you probably already know, there is a quite inconvenient bug in
sid+lenny's aufs, which is blocking renames, caused by deadlocks. That
means that one can't update the apt cache through apt-get/aptitude, at
the very least (it's not like rename() is something very rare anyway),
which IMHO makes it unfit for a stable release.
For more details, initial upstream bugreport:
http://article.gmane.org/gmane.linux.file-systems.aufs.user/1270
The patch as provided by upstream:
http://article.gmane.org/gmane.linux.file-systems.aufs.user/1291
The thread contains various confirmations that the patch does its job
and fixes the deadlocks. I personally tested it against a custom
snapshot I prepared: 20080714 (I didn't know 20080719 would follow some
days later, and I was checking whether the bug got fixed in the
meanwhile), but also with 0+20080719-1, against which I attach a
debdiff, so that you can eventually merge the patch quickly.
I kept the patch as is, only adapting the patch level. Feel free to
drop/adapt attribution lines in the patch/the changelog, nothing fancy
in preparing an upload. More precisely: I needed to do so to prepare
some (better-working) LiveCD images.
Cheers,
