Using spamassassin with selinux



Hi,

I'm still trying to get spamassassin to work properly with procmail selinux (this is bug #172088, been open almost 50 days, still not closed). I'm getting a bit tired of watching my spam system fail and will probably revert to no selinux testing at all (selinux=0, like almost everyone else) if this continues. 50 days is more than enough to fix a reported problem.

I have the following entry in my procmail :

:0fw: .spamc.lock
* < 256000
| spamc

Now maildir logs show spamassassin is denied access to its own files when selinux is enabled :

Dec 17 11:30:05 rousalka spamd[2681]: spamd: connection from localhost.localdomain [127.0.0.1] at port 50637
Dec 17 11:30:05 rousalka spamd[2681]: spamd: setuid to nim succeeded

(yes spamd does setuids)

Dec 17 11:30:05 rousalka spamd[2681]: spamd: creating default_prefs: /home/nim/.spamassassin/user_prefs

(spamd didn't see the pref files already existed - probably because of selinux - so it tries to create it)

Dec 17 11:30:05 rousalka spamd[2681]: mkdir /home/nim: Le fichier existe. at /usr/lib/perl5/vendor_perl/5.8.7/Mail/SpamAssassin.pm line 1467

(the system tells it to get lost, the file already exists)

Dec 17 11:30:05 rousalka spamd[2681]: config: cannot write to /home/nim/.spamassassin/user_prefs: Permission non accordée

(and spamd is not allowed to write it)

Dec 17 11:30:05 rousalka spamd[2681]: spamd: failed to create readable default_prefs: /home/nim/.spamassassin/user_prefs

likewise pyzor is dead

Dec 17 11:30:05 rousalka spamd[2681]: internal error
Dec 17 11:30:05 rousalka spamd[2681]: pyzor: check failed: internal error

and the autowhitelist can not be modified, because spamd can not create a lockfile

Dec 17 11:30:05 rousalka spamd[2681]: locker: safe_lock: cannot create tmp lockfile /home/nim/.spamassassin/auto-whitelist.lock.rousalka.dyndns.org.2681 for /home/nim/.spamassassin/auto-whitelist.lock: Permission non accordée Dec 17 11:30:05 rousalka spamd[2681]: auto-whitelist: open of auto-whitelist file failed: locker: safe_lock: cannot create tmp lockfile /home/nim/.spamassassin/auto-whitelist.lock.rousalka.dyndns.org.2681 for /home/nim/.spamassassin/auto-whitelist.lock: Permission non accordée Dec 17 11:30:05 rousalka spamd[2681]: Can't call method "finish" on an undefined value at /usr/lib/perl5/vendor_perl/5.8.7/Mail/SpamAssassin/Plugin/AWL.pm line 397.

This on a fully relabeled selinux-policy-targeted-2.1.6-8 rawhide system
