** Description changed: - Sorry for not being of any help here. I don't really know what happened. - There was suddenly a report about a system problem. and apport started. - just updated a few hours ago. + [Impact] + 12.04.2 users cannot share dirs with Samba due to smbd crashing with "sys_setgroups failed". + With 12.04.2 shipping linux-generic-lts-quantal, Samba is now completely unusable due to this bug, so an SRU is justified. + The fix has been included upstream and is Fix-Released in the current development versions of Ubuntu (Quantal+). + + [Test Case] + Right click on a folder, e.g. ~/share, from nautilus, and select to share it. + If prompted to install Samba, do so, then logout/login and start over the test case. + Then run `nautilus-connect-server`, select + Type: Windows share, + Server: localhost, + Share: share, + Domain name: WORKGROUP, + User name: your unix username, + Password: your unix password. + + and press the [Connect] button. It will fail, and /var/log/samba/log.hostname will contain an smbd crash with the following lines among others: + [2013/02/18 12:51:16.500421, 0] lib/util.c:1117(smb_panic) + PANIC (pid 7594): sys_setgroups failed + + [Regression Potential] + Since the bug was fixed upstream, and since Samba is now completely unusable, regressions are not very likely. + + + [Original bug description] + Sorry for not being of any help here.
