Subject: [refpolicy] [PATCH 1/1] Allow xfce (and most likely other DEs) to properly work with the authorization information

On my system, I use XFCE and start X from the commandline (using "startx")
rather than through a graphical DM. During the start-up, XFCE4 creates
temporary ICE files in /tmp (like /tmp/.xfsm-ICE-ABCDEF) which are later
read in by iceauth and at some point X.

I'm not that good at the entire ICE stuff, but without this, I was unable to
shut down my session ("log off").

What specific process was creating the files? Do you still have the
logs? I'm interested in seeing them, as user processes creating ICE
files seems wrong.

You'd be surprised who all maintained these:

manage_dirs_pattern($1_gsession_t, gsession_ice_tmp_t, gsession_ice_tmp_t)
manage_sock_files_pattern($1_gsession_t, gsession_ice_tmp_t,
gsession_ice_tmp_t)
files_tmp_filetrans($1_gsession_t, gsession_ice_tmp_t, dir)
# for when /tmp/.ICE is created with initrc_tmp_t
init_script_tmp_filetrans($1_gsession_t, gsession_ice_tmp_t, sock_file)
# for when /tmp/.ICE is created with xdm_tmp_t
xserver_xdm_tmp_filetrans($1_gsession_t, gsession_ice_tmp_t, sock_file)

Sure, easily reconstructed, it's xfce4-session (as per the following
auditallow granted log lines):
