Hi, I noticed that in 2.6.5 /var/log/audit permission were dropped from
750 to 600. I am fine with that but while I see the motivation [1], I
just cannot find where is that happening in the code. Besides, specfile
still contains:
%attr(750,root,root) %dir %{_var}/log/audit
and hence 'rpm -V audit' obviously fails.

The directory should be 0750 or 0700 depending on your config. 0600 would be a
mistake.

Maybe I should take the attr away or modify it to (-,root,-). The group can
change. For example, I have wheel allowed to run audit reports on my system.

Yeah. Hmm.

Sorry, it was a typo - it should be 0700 (not 0600).

Thanks, now it is clear. You one thing - line 903 suggests that it is
either 0700 or 0770 which I can confirm by testing:
# # log_group = root
# ls -ld /var/log/audit/
drwx------. 2 root root 4096 Jul 21 09:56 /var/log/audit/
# # log_group = input
# ls -ld /var/log/audit/
drwxrwx---. 2 root input 4096 Jul 21 09:56 /var/log/audit/

Yeah. Hmm.
Yes, change you mentioned would solve 'rpm -V' problem. It sounds very
reasonable since both group ownership and permission are configurable
via auditd.conf.

Fixed in commit 1360.

Also fixed in the same commit.
