Hi,
The lspp.31 kernel has been published to the lspp yum repo at:
http://people.redhat.com/sgrubb/files/lspp
The changes are:
- New netlabel patch from Paul
- Added patch to fix NULL ptr deref from Amy.
Please let me know if this kernel has any problems.
The following scenario does not work on my machine (it results in an OOPS):
1. reboot
2. login as root
3. auditctl -l (until you get no rules, running under MLS so I'm still
seeing the Error permission denied problem).
4. auditctl -a exit,always -S chmod -F path=/root/file
5. auditctl -l (confirm rule added)
6. auditctl -D << oops
[this also happens with the auditctl -d style delete]
The following is the dump:
BUG: unable to handle kernel paging request at virtual address 6b6b6b6b
