Description Gordon Messmer 2008-12-19 17:26:27 UTC 
Description of problem:
On a freshly installed system (testing under CentOS), mailman is not able to update its archives.  audit.log contains messages like:

type=AVC msg=audit(1229707095.625:82): avc:  denied  { search } for  pid=3973 comm="python" name="archives" dev=hda2 ino=224254 scontext=root:system_r:mail
man_mail_t:s0 tcontext=system_u:object_r:mailman_archive_t:s0 tclass=dir

The source and target contexts look correct.  I believe that archiving was probably overlooked when bug 350511 was fixed.

I was able to restore functionality by entering permissive mode and using audit2allow to generate this policy:

module localMailman 1.0;

require {
	type mailman_mail_t;
	type mailman_archive_t;
	class lnk_file create;
	class dir { write search remove_name create getattr add_name };
	class file { setattr read create write getattr link unlink append };
}

#============= mailman_mail_t ==============
allow mailman_mail_t mailman_archive_t:dir { write search remove_name create getattr add_name };
allow mailman_mail_t mailman_archive_t:file { setattr read create write getattr link unlink append };
allow mailman_mail_t mailman_archive_t:lnk_file create;



Version-Release number of selected component (if applicable):
mailman-2.1.9-4.el5
selinux-policy-2.4.6-137.1.el5

How reproducible:
Always

Steps to Reproduce:
1. Configure mailman according to /usr/share/doc/mailman-2.1.9/INSTALL.REDHAT
2. Send message
3. Check audit.log
