AVC from sendmail & rkhunter

[Steven Stern]

rkhunter is unhappy with my system (due to tomboy and /dev/shrm) but
that's another story.

When sendmail tries to notify me that rkhunter is unhappy, it generates
and AVC:

SELinux is preventing /usr/sbin/sendmail.sendmail from getattr access on
the file /var/lib/rkhunter/rkhcronlog.bQnsKgU7Y1.

*****  Plugin restorecon (99.5 confidence) suggests
*************************

If you want to fix the label.
/var/lib/rkhunter/rkhcronlog.bQnsKgU7Y1 default label should be var_lib_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /var/lib/rkhunter/rkhcronlog.bQnsKgU7Y1

*****  Plugin catchall (1.49 confidence) suggests
***************************

If you believe that sendmail.sendmail should be allowed getattr access
on the rkhcronlog.bQnsKgU7Y1 file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep sendmail /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
