As of F27, dbus-broker unconditionally fails on boot when SELinux is enabled with AVC avc: denied { map } for pid=985 comm="dbus-broker" path=2F6D656D66643A646275732D62726F6B65722D6C6F67202864656C6574656429 dev="tmpfs" ino=31832 scontext=system_u:system_r:system_dbusd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:tmpfs_t:s0 tclass=file permissive=0
Are you able to reproduce it? Could you attach reproducer? Thanks, Lukas.
Yes, just boot with dbus-broker and SELinux enabled on F27. `systemctl enable dbus-broker && systemctl --global enable dbus-broker`. We mmap an memfd that we use to write log-messages into. So due to the new SELinux mmap feature this fails any time we attempt to write to the log (taking down the daemon).
