This bug misses SRU justification, please update this bug with it as explained on https://wiki.ubuntu.com/KernelTeam/StableHandbook/StableProcess#Workflow_for_SRU_Patches Also, this bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- natty' to 'verification-done-natty'. If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Bug 791019] Re: yama_ptracer_del lockdep warning
Now security_task_free is called from __put_task_struct in ubuntu kernel, and __put_task_struct c can surely be called in softirq context.In upstream, there are no security_task_free at all. If not calling security_task_free, where is it called from? Seems depending on security implementation, also more difficult fix will be involved than *_bh fix. Any way, using spin_[un]lock_bh is a easy fix, and no obvious performance degrade is introduced. I don't know security well, so let your guys decide how to fix this, :-) thanks, -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/791019 Title: yama_ptracer_del lockdep warning To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/791019/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 791019] Re: yama_ptracer_del lockdep warning
Thanks for catching this! Is this perhaps a problem at a higher level? (I.e. should security_task_free be called in a different way so that its hooks (like yama_ptracer_del) do not need to use the _bh locking mechanisms? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/791019 Title: yama_ptracer_del lockdep warning To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/791019/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
