Package: glusterfs
Version: 11.1-4
Severity: normal
Dear Maintainer,
in Ubuntu we got a bug report[1] on glusterfs 11.1-4 (which was in
sync with debian), that it would segfault under certain conditions on
a user's system.
The reporter tracked the problem down to an upstream PR that
introduced it, and then to another PR that fixed it:
* PR which introduced the bug: https://github.com/gluster/glusterfs/pull/1763
* PR which added this patch: https://github.com/gluster/glusterfs/pull/4302
* Issue discussion: https://github.com/gluster/glusterfs/issues/4295
This bug report and supporting data was good enough for the Ubuntu SRU
process, which was completed successfully.
I suppose debian users could be affected as well, so I'm filing this
bug here with the patch that was used in the Ubuntu update.
1. https://bugs.launchpad.net/ubuntu/+source/glusterfs/+bug/2064843
Description: Fix stack overflow in __inode_destroy
A recursive call to inode_unref was introduced when support for inode-level
namespaces was added. This results in a stack overflow under certain
conditions leading to brick SEGFAULTs. This patch removes the recurisve call
to inode_unref. This was fixed upstream but is yet to be included in a
release.
