Description Adam Williamson 2014-10-21 21:01:03 UTC
Testing deployment of FreeIPA via Rolekit in Fedora 21 Beta TC4.

To reproduce, install Beta TC4 from Server DVD and follow https://fedorahosted.org/rolekit/wiki/DomainController .

In /var/log/audit/audit.log I see these denials:

type=USER_AVC msg=audit(1413923153.653:461): pid=731 uid=81 auid=4294967295 ses=4294967295 subj=system_u:system_r:system_dbusd_t:s0-s0:c0.c1023 msg='avc:  denied  { send_msg } for msgtype=method_return dest=:1.23 spid=3366 tpid=1876 scontext=system_u:system_r:certmonger_t:s0 tcontext=system_u:system_r:unconfined_service_t:s0 tclass=dbus  exe="/usr/bin/dbus-daemon" sauid=81 hostname=? addr=? terminal=?'
type=USER_AVC msg=audit(1413923178.251:462): pid=731 uid=81 auid=4294967295 ses=4294967295 subj=system_u:system_r:system_dbusd_t:s0-s0:c0.c1023 msg='avc:  denied  { send_msg } for msgtype=method_return dest=:1.23 spid=3366 tpid=1876 scontext=system_u:system_r:certmonger_t:s0 tcontext=system_u:system_r:unconfined_service_t:s0 tclass=dbus  exe="/usr/bin/dbus-daemon" sauid=81 hostname=? addr=? terminal=?'

Getting the time stamps with ausearch, they coincide with this block in the journal. The first denial coincides with the last *successful* action (enabling of certmonger.service) which occurs before this block is shown, and the second denial occurs at the same time as this output block appears.

As this causes FreeIPA deployment to fail, nominating as a Beta blocker bug per criterion:

"Release-blocking roles and the supported role configuration interfaces must meet the core functional Role Definition Requirements to the extent that supported roles can be successfully started, stopped, brought to a working configuration, and queried."
