Description Warren Togami 2009-09-24 05:43:08 UTC
spamassassin has an optional tool sa-compile which uses re2c to compile regular expressions into C source, which is then compiled into loadable .so libraries.  These .so libraries are placed into standard locations.  spamd reads these standard directories and uses them for pattern matching if they exist.

SELinux is currently blocking execution of these .so files from spamd.

Error in /var/log/maillog:
Sep 24 01:33:08 master3 spamd[21288]: Can't load '/var/lib/spamassassin/compiled/5.008/3.003000/auto/Mail/SpamAssassin/CompiledRegexps/body_0/body_0.so' for module Mail::SpamAssassin::CompiledRegexps::body_0: /var/lib/spamassassin/compiled/5.008/3.003000/auto/Mail/SpamAssassin/CompiledRegexps/body_0/body_0.so: failed to map segment from shared object: Permission denied at /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/XSLoader.pm line 70. 

Expected in /var/log/maillog:
Sep 24 01:35:19 master3 spamd[21378]: zoom: able to use 1445/1447 'body_0' compiled rules (99.861%)

audit2allow on this AVC allows it work.

Please include this in both Fedora and RHEL-5 selinux-policy.

If you run restoreocn on this directory it will be labeled correctly, and the spam would be logged
