http://bugzilla.opensuse.org/show_bug.cgi?id=941867 Bug ID: 941867 Summary: Upgrade from openSUSE 13.2 to Tumbleweed yields a kernel panic while update apparmor-abstraction Classification: openSUSE Product: openSUSE Factory Version: 201505* Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: AppArmor Assignee: suse-beta@cboltz.de Reporter: ronisbr@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I needed to install openSUSE 13.2 and then upgrade to Tumbleweed because the installation of the latter always crashes here (the bug was already reported). However, when I tried to upgrade following the procedures in Wiki, I got a Kernel panic while the package apparmor-abstraction was being updated. I tried twice with the same error at the same installation step. I found another person who had the same problem in a Spanish forum [1]. As far as I can tell, he solved the issue by uninstalling apparmor. However, I could also solve the problem by just disabling it using: `systemctl stop apparmor` before `zypper dup`. Unfortunately, I did not take a screenshot of the Kernel message and it is not possible right now to format my machine and reinstall Tumbleweed. ------ [1] http://www.forosuse.org/forosuse/showthread.php?t=32755 -- You are receiving this mail because: You are on the CC list for the bug.

I discussed this bug with John (upstream AppArmor developer, including the kernel parts) on IRC. He can guess some possible reasons, but can't tell exactly what happened without the kernel messages. Therefore I'm afraid that you (or someone else) will need to re-install 13.2 and then update to tumbleweed again to capture the kernel messages :-( Please also attach /var/log/zypp/history so that I can see the installation order. (In theory that shouldn't matter, but in practise it could still be helpful to know.) -- You are receiving this mail because: You are on the CC list for the bug.

Stopping apparmor before your upgrade is a valid work around for this issue. -- You are receiving this mail because: You are on the CC list for the bug.

I have attached a patch that will keep the bug() call from triggering. It does not address the root cause, as it leaks some memory instead of dealing with why the subprofiles have not been freed at this point.

Yeah, BUG() seems like a overkill for small memory leaks. Maybe WARN()? I'm going to backport this in anyway. Meanwhile, would you merge this to upstream, too? -- You are receiving this mail because: You are on the CC list for the bug.

The call trace here doesn't really help with the debugging as the freeing of these objects via refcount paths is disconnected from the code that is managing the policy (load/replace/remove). -- You are receiving this mail because: You are on the CC list for the bug.
