apparmor_parser triggers a kernel panic

[Paolo Pisati]

SRU Justification:

    Impact: kernel panic when loading a malformed apparmor profile.
    Fix: see attached patch.
    Testcase: /etc/init.d/apparmor restart

===

While loading a new profile, in case of a malformed one, policy.c::aa_interface_replace_profiles() tries to free an ERR_PTR leading to a panic.

[Paolo Pisati (p-pisati)]

Patch submitted to kernel-list for SRU to Lucid and Maverick.

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' to 'verification-done'.

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.
