Description Karel Volný 2013-06-25 19:10:32 UTC
Description of problem:
Please disable dontaudit rules for lightdm.
This has just costed me more than hour of life because I've hit bug 969090. Selinux was my first suspect, but as I could not find anything in audit.log (see bug 967199#c1), I tried other false traces.
Googling and interacting with Bugzilla through links text mode interface, as for some reason I could not get X session working without dm was a real pleasure ...

Version-Release number of selected component (if applicable):
selinux-policy-3.12.1-54.fc19

How reproducible:
always

Steps to Reproduce:
1. use razorqt with lightdm
2. use selinux-policy-3.12.1-54.fc19
3. after unsucessful GUI startup, login in text on second console
4. grep light /var/log/audit/audit.log | grep AVC
5. run lightdm manually and try to login
6. grep light /var/log/audit/audit.log | grep AVC

Actual results:
4. nothing
6.
type=AVC msg=audit(1372182105.389:231): avc:  denied  { read open } for  pid=1611 comm="lightdm" path="/usr/bin/razor-lightdm-greeter" dev="dm-0" ino=10497833 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:spamc_exec_t:s0 tclass=file
type=AVC msg=audit(1372182105.389:231): avc:  denied  { execute_no_trans } for  pid=1611 comm="lightdm" path="/usr/bin/razor-lightdm-greeter" dev="dm-0" ino=10497833 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:spamc_exec_t:s0 tclass=file

Expected results:
well, primarily no errors, as bug 969090 should be fixed ... but when it's still there, you should get error messagess in all cases of broken lightdm startup, no matter if started from the init system or manually

Additional info:
have I said already that I hate dontaudit rules in general?
