[rsbac] Kernel oops

[Mathew Johnston]

I just had a kernel oops.

I'm running RSBAC from
http://rsbac.org/kernels/linux-2.4.19-rsbac-v1.2.1.tar.bz2 with admin
tools http://rsbac.org/code/rsbac-admin-v1.2.1.tar.gz. I was just adding
an ACL entry to RSBAC when it seemed to freeze, I then hit CTRL C and it
dropped to a shell, then I tried to run rsbac_menu again, and it just
sat there... I went to the actual machine (I had been connected via SSH)
and there was a kernel oops displayed.

Here's the output:
