Running strict/enforcing, latest rawhide.
I finally got around to 'blowing the dust off' of my strict PC. I updated to latest rawhide, did a 'fixfiles relabel', and rebooted.
Graphical login failed. Appears that xdm is failing on creating a sem:

Adding: allow xdm_t self:sem { create unix_read unix_write }; to xdm.te seems to fix this. That OK?
I will add.
Also, running firefox proxied through privoxy generates:Better solution is to add 8118 to the list of http_cache_port_t in net_contexts

or
allow user_mozilla_t port_t:tcp_socket name_connect;
That right?
portcon tcp 8118 system_u:object_r:http_cache_port_t
Your solution allows mozilla to connect to any ports.
