Created bug 357581 to fix apparmor smbpass abstraction. I'm not sure it will ultimately fix this problem, but it would surely explain why the bug appeared in Samba 3.2 (LDB files weren't in use before) and why this seems to be Ubuntu-specific (our cupsd/apparmor thing is Ubuntu- specific). There would still be a bug in samba for failing so badly in this case but the root cause might be avoided. -- segfault in pam_smbpass.so https://bugs.launchpad.net/bugs/303458 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Still struggling to reproduce this. There seems to be something CUPS-related that results in secrets.tdb corruption with "Unable to open tdb '/var/lib/samba/group_mapping.ldb'" error messages. Once corrupted, this file seems to trigger libpam- smbpass segfaults. Following the error message lead, it might come from CUPS apparmor profile, preventing access to LDB.

[Bug 303458] Re: segfault in pam_smbpass.so
Came across this issue just last night and found the cause to be less than insidious. Seems that after I finished editing smb.conf, the daemon reloaded the new file automagically. This is when the trouble started. As it turns out, my new config had a typo and was specifying a directory that did not exist. I believe this is what was causing samba to go tango-uniform and thus causing pam to segfault. One boot into recovery mode and a restore to the default smb.conf later, and all is well again. I will be editing my smb.conf under a different name until it has passed testparm.

[Bug 303458] Re: segfault in pam_smbpass.so
There was probably a problem with corrupted contents in /var/lib/samba... this tends to occur a little too often in my taste and pam_smbpass integration makes it fail quite badly. I'm not exactly sure what we can do to avoid it though. ** Changed in: samba (Ubuntu) Status: Incomplete => New -- segfault in pam_smbpass.so https://bugs.launchpad.net/bugs/303458 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 303458] Re: segfault in pam_smbpass.so
Thanks for your help ! I said, in my comment 4, that I have try to rm -rf /var/lib/samba and re-intall package. But, I have not try to uninstall every samba packages... :( And now, as I need a working computer ( working on a project ), I have re-install everything and now, no errors. -- segfault in pam_smbpass.so https://bugs.launchpad.net/bugs/303458 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 303458] Re: segfault in pam_smbpass.so
zedtux: OK, then we can try to cleanup by hand: $ sudo rm -rf /var/lib/samba $ sudo mkdir /var/lib/samba pam_smbpass.so is known to segfault if the /var/lib/samba directory doesn't exist, or if it is non-empty, filled by something it doesn't like. I never saw it segfault when using an existing, but empty /var/lib/samba... yet :) (As I said in comment 3, to clean up, you should have purged *both* samba-common and libpam-smbpass, ensure that /var/lib/samba has been removed, and then reinstall libpam-smbpass (which will reinstall samba- common in the process). That's because the /var/lib/samba directory is installed by the samba-common package, not the libpam-smbpass one.) -- segfault in pam_smbpass.so https://bugs.launchpad.net/bugs/303458 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 303458] Re: segfault in pam_smbpass.so
So, I have back in rescue mode and do all possible updates. After that, I did an ls /var/lib/samba and saw many files. So did the apt-get remove --purge libpam-sbmpass and then, execute again an ls /var/lib/samba. Files still there ! So, I did a rm -rf /var/lib/samba, and then apt-get install libpam- sbmpass. Next step, I continue boot process and try, in a terminal to do sudo apt-get update and again segmentation fault !

[Bug 303458] Re: segfault in pam_smbpass.so
About the workaround: could you confirm that /var/lib/samba is removed after you purged libpam-smbpass and samba-common ? -- segfault in pam_smbpass.so https://bugs.launchpad.net/bugs/303458 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

I have already done the workaround of the comment ( I tell that at the end of my ticket ). No, it's a fresh new installation.

Could you try the workaround in: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/302092/comments/4 Is it a 8.04 box that was upgraded to 8.10 ?
