Description Hicham HAOUARI 2011-05-10 11:02:34 UTC
SELinux is preventing /usr/bin/gtk-gnash from unix_read, unix_write access on the semaphore Unknown.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that gtk-gnash should be allowed unix_read unix_write access on the Unknown sem by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep gtk-gnash /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2011-05-11 08:22:35 UTC
What were you doing?

Comment 2 Hicham HAOUARI 2011-05-13 23:19:44 UTC
I probably was using gnash inside a sandbox

Comment 3 Miroslav Grepl 2011-05-16 20:16:44 UTC
Did it work?

Comment 4 Daniel Walsh 2011-05-17 08:07:18 UTC
If it works we can probably dontaudit the access.

Comment 5 Hicham HAOUARI 2011-05-17 08:52:25 UTC
