+++ This bug was initially created as a clone of Bug #1279006 +++ Description of problem: Trying to specify an mls/mcs security level to run an X based sandbox fails Version-Release number of selected component (if applicable): policycoreutils-python-utils-2.4-14.fc23.x86_64 How reproducible: Always Steps to Reproduce: 1. Try to start and X based sandbox 2. 3. Actual results: sandbox -X -t sandbox_web_t -l s0:c455,c394 -H ~/firefox_home/ -T ~/firefox_tmp/ firefox /usr/bin/sandbox:440: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded. from gi.repository import Gtk grep: /home/user/.sandboxrc: Permission denied mkdir: cannot create directory ‘/home/user’: Permission denied /usr/share/sandbox/sandboxX.sh: line 10: /home/user/.config/openbox/rc.xml: Permission denied audit msg type=SELINUX_ERR msg=audit(1446866347.983:1067): op=security_bounded_transition seresult=denied oldcontext=unconfined_u:unconfined_r:sandbox_web_t:s0:c394,c455 newcontext=unconfined_u:unconfined_r:sandbox_xserver_t:s0:c394,c455 Expected results: The X based sandbox starts just as it would if the level was left to be random. Additional info: --- Additional comment from Miroslav Grepl on 2015-11-09 03:14:13 EST --- Nice catch. It looks there is more issues and given MCS is not propagated. The mentioned AVC does not block it. There are another AVCs caused by this reproducer.
Mirek, do you have these AVCs? Thank you.
