Looks like the change to how /proc/kallsyms displays addresses was
introduced in:
commit d97106ab53f812910a62d18afb9dbe882819c1ba
Author: Linus Torvalds <torva...@linux-foundation.org>
Date: Sat Jan 3 11:46:17 2009 -0800
Make %p print '(null)' for NULL pointers
Upstream fixed it in 3a129cc2151425e5aeb69aeb25fbc994ec738137 but was
not originally submitted to linux-stable (that has been rectified).
It could be worked around in the qrt script, but I'm not convinced
that's the right thing to do here.
It should be noted that the behavior that the script is testing for,
kernel addresses in /proc/kallsyms not being visible to unprivileged
processes, is correct here. So there's no security impact from this, and
it should not block promoting kernels, from the security team's
perspective.
