[abrt] crash in samba-client-0:3.5.2-59.fc13: Process /usr/bin/smbclient was killed by signal 11 (SIGSEGV)
Last modified: 2010-05-21 05:55:50 EDT
abrt 1.0.9 detected a crash.
Attached file: backtrace
cmdline: smbclient //172.22.22.2/pub
reason: Process /usr/bin/smbclient was killed by signal 11 (SIGSEGV)
release: Fedora release 13 (Goddard)
The crash is reliably triggered when trying (by any means and/or abstraction levels, thus indicating a libsmbclient bug) to access a SMB share on a server that has share-level security enabled, i.e. security=share in the [global] section of smb.conf.
172.22.22.2 is the local machine, incidentally, but the crash occurs when trying to access any other machine that is similarly configured. Accessing this or other machines using share-level security works flawlessly from Fedora 11, Fedora 12, CentOS 5.x, RHEL 5.x, and Microsoft OSes.
From what I can see, bugs 573438, 581954, 583516 describe the same situation. Opening a new bug since all the others were on the x86_64 arch, and this one has a complete debuginfo backtrace.
How to reproduce
1. smbclient //172.22.22.2/pub

As far as I can tell, this looks like Samba bug #7250 (see https://bugzilla.samba.org/show_bug.cgi?id=7250 ). That bug suggests that the patch at
fixes the issue.
I can confirm that the upstream patch fixes the issue. I've rebuilt the samba packages locally including that patch and smbclient, as well as everything else linking against the SMB client libraries, works fine.
I've attached the upstream patch and the diff for the specfile I used below.

Patch to fix the SIGSEGV issue.

Erroneously saved the upstream patch as samba-3.2.5* instead of samba-3.5.2*. Oops. Obviously, it should be named according to the 3.5.2 release.

This bug was discussed at the 2010/04/30 blocker review meeting.
Although it's a serious issue, we agreed it's not a blocker as it can be properly fixed by an update. However, it seems the fix is already known, and we would happily take the fix into the final release if it is ready in time.
Can Simo, jlayton or gdeschner please apply the fix and submit a new build as an update ASAP? We're working to a target date of 2010/05/04 to start building the RCs, so we really need the package to be available by then to get it in for final release. Thanks!

Thanks, Adam. I did a bit of soul-searching on whether to add it to F13Blocker or F13Target and finally decided on F13Blocker mostly due to potential PR issues for new users. Obviously it's no longer an issue at this end once a fix was found (I can live with local packages just fine) and I'd rather not see the likelihood of a release slip increased. I'll see it in an update then :)
samba-3.5.2-60.fc13 has been submitted as an update for Fedora 13.
I built a package with the patch. And I pushed it directly to stable in bodhi.
Adam can you check it gets included in F13 ?
Thanks, Simo, reconfirmed it fixes the issue and doesn't wreak any havoc. will you or Adam be closing the bug as fixed, or should I?
samba-3.5.2-60.fc13 has been pushed to the Fedora 13 stable repository. If problems still persist, please make note of it in this bug report.
I also affected by this problem. And I do not see such update in Fedora 13 updates (nor in testing http://download.fedora.redhat.com/pub/fedora/linux/updates/testing/13/i386/ nor in stable http://download.fedora.redhat.com/pub/fedora/linux/updates/13/i386/). Have it pushed? Or I search in wrong place (yum also do not found it automatically)?
Look also here - http://download.fedora.redhat.com/pub/fedora/linux/development/13/i386/os/Packages/ . In rawhide ( http://download.fedora.redhat.com/pub/fedora/linux/development/rawhide/i386/os/Packages/ ) even older version - samba-3.5.0-55rc3.fc14
Pavel, it takes time for the mirrors to sync. A bit of patience would be in order. If you really, really, really must have the new packages *right now*, you can always click on Simo's Koji link, https://admin.fedoraproject.org/updates/samba-3.5.2-60.fc13 , and install the packages manually. but I recommend a bit of patience.
Thank you. I test it and it seams fix it bug.
The patch is already provided by upstream (Samba 3.5.3). Updating to the -61 packages (currently in updates-testing) should also do the trick.
