Description Göran Uddeborg 2020-05-05 09:30:40 UTC
(This is a followup to bug 1711799 which got mostly solved, but had some residue.  Since that bug has become a bit messy, I'm creating this separate report for the remainder.)

Description of problem:
The sa-update cron job wants to condrestart the spamassassin service after having downloaded updated information.  It isn't allowed to do that.


Version-Release number of selected component (if applicable):
selinux-policy-targeted-3.14.5-32.fc32.noarch


Steps to Reproduce:
1. Enable spamassassin and sa-update


Actual results:
The spamd daemon is not restarted, and those AVC:s show up in the log:

type=USER_AVC msg=audit(1588631772.884:584901): pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='avc:  denied  { start } for auid=n/a uid=0 gid=0 path="/usr/lib/systemd/system/spamassassin.service" cmdline="" scontext=system_u:system_r:spamd_update_t:s0 tcontext=system_u:object_r:systemd_unit_file_t:s0 tclass=service permissive=0  exe="/usr/lib/systemd/systemd" sauid=0 hostname=? addr=? terminal=?'

Expected results:
The spamd server should have been restarted.


Additional info:

The following additional module seems to fix the problem.

module sa-updatefix 1.12;

require {
	type init_t;
        type spamd_update_t;
	type systemd_unit_file_t;
	all_kernel_class_perms
}

allow spamd_update_t init_t:system status;
allow spamd_update_t systemd_unit_file_t:service { start };

Comment 1 Zdenek Pytela 2020-05-05 12:21:02 UTC
Hi,

Thank you for reporting the issue. We need to confine /usr/lib/systemd/system/spamassassin.service which will need a few more changes in other modules.

I believe this bug is a duplicate of BZ#1819017.

Comment 4 Göran Uddeborg 2020-11-05 20:38:25 UTC
Except that bug is for Fedora 31, it does indeed seem to be a duplicate.
