Description Eric Sandeen 2008-01-14 19:00:50 UTC

The recent Coverity changes (bug #239354) brought back upstream changes which
included a use of a potentially uninitialized pointer.

Fixed upstream,

Comment 1 RHEL Program Management 2008-01-14 19:05:41 UTC

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update
release.

In e2fsprogs-1.39-13.el5

Comment 6 wingc 2008-02-14 21:50:58 UTC

I hit this bug in real life today, on a RHEL5.1 system: the filesystem had
apparently become corrupted after a suspend/resume cycle.

The current e2fsck in RHEL5 (from e2fsprogs-1.39-10.el5_1.1) died with a
segfault in region_free().

After rebuilding the RPM with the above patch from e2fsprogs.git, I was able to
repair the filesystem.

So I think this update needs to get pushed out for RHEL5 when feasible;
otherwise some people will probably end up with unbootable/unfixable systems.

Comment 7 Eric Sandeen 2008-02-14 21:55:25 UTC

This fix is indeed slated for a RHEL5 update.

Thanks,
-Eric
