Hey Steve,
I'm seeing an oops in the .29 and .30 kernels (I've tested this with the
.27 and .28 kernels, and they do not experience this problem). With
audit-1.2.3-1, rule addition works fine, but rule deletion is causing an
oops.
auditctl -a entry,always -S chmod
auditctl -D _OR_ auditctl -d entry,always -S chmod
These actions resulted in the following oops:
BUG: unable to handle kernel NULL pointer dereference at virtual address
00000010
printing eip:
c044840e
