Bug ID: 1393649
Summary: ejabberd's unit file should not launch ejabberdctl
with /usr/bin/bash
Product: Fedora
Version: rawhide
Component: ejabberd
Severity: medium

Depends On: 1393643
External Bug ID: Github processone/ejabberd/issues/1375
Description of problem:
Currently, ejabberdctl is launched by systemd with /usr/bin/bash instead of
being launched directly. This causes the process to run in the initrc_t context
which is very permissive. Instead, systemd should launch ejabberdctl directly.
However, there are two blockers to getting this change done and working, as we
get these AVC denials with this change in place:
type=AVC msg=audit(1478751171.862:648): avc: denied { write } for pid=2989
comm="async_2" name="ejabberd.pem" dev="dm-1" ino=44546
scontext=system_u:system_r:rabbitmq_t:s0
tcontext=unconfined_u:object_r:etc_t:s0 tclass=file permissive=0
type=AVC msg=audit(1478751171.863:649): avc: denied { write } for pid=2989
comm="async_2" name="ejabberd.pem" dev="dm-1" ino=44546
scontext=system_u:system_r:rabbitmq_t:s0
tcontext=unconfined_u:object_r:etc_t:s0 tclass=file permissive=0
type=AVC msg=audit(1478751171.865:650): avc: denied { name_bind } for
pid=2986 comm="beam" src=5349 scontext=system_u:system_r:rabbitmq_t:s0
tcontext=system_u:object_r:unreserved_port_t:s0 tclass=tcp_socket permissive=0
I've filed a bug upstream to request that they stop trying to open the certfile
in write mode[0], and I've filed a bug against selinux-policy to request that
ejabberd be allowed to use tcp port 5349[1]. Once both of those bugs are fixed,
we can proceed with dropping /usr/bin/bash presuming that we don't then hit
further AVC denials (which could happen).
