Description Robert Scheck 2006-02-12 13:51:32 EST
Description of problem:
I got the following avc denied messages during the last sendmail upgrade - but 
I've got also MIMEDefang running, maybe one or another message is caused by
this combination?!

Expected results:
No avc messages ;-)
Comment 1 Daniel Walsh 2006-02-13 10:14:21 EST
Sendmail is leaking file descriptors to /etc/mail/submit.mc and mimedefang.sock

You need to make sure file descriptors are closed on exec.
Comment 2 Daniel Walsh 2006-02-13 10:18:15 EST
Should /var/spool/MIMEDefang/ be labeled mail_spool_t?
Comment 3 Thomas Woerner 2006-02-17 11:37:45 EST
MIMEDefang is not part of sendmail. Are sou sure, that this is a problem of
sendmail and not mimedefang?
Comment 4 Robert Scheck 2006-02-17 11:42:45 EST
I'm not sure, as I already wrote.

But audit 1139661609.634 looks to be sendmail related, because nothing in my /
etc/mail/submit.mc is directly pointing to MIMEDefang. Or am I wrong?

Nevertheless, maybe there should be a upstream selinux-policy for MIMEDefang? ;)
Comment 5 Florian La Roche 2007-01-23 04:45:00 EST
Is this fixed with the current devel tree?
