SELinux is preventing /usr/lib/nspluginwrapper/npviewer.bin from 'read, write' accesses on the chr_file card0.

*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************

If you want to allow regular users direct dri device access
Then you must tell SELinux about this by enabling the 'user_direct_dri' boolean.
# setsebool -P user_direct_dri 1

*****  Plugin catchall (11.6 confidence) suggests  ***************************

If you want to allow npviewer.bin to have read write access on the card0 chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep /usr/lib/nspluginwrapper/npviewer.bin /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2010-11-15 12:34:50 UTC
What plugin were you using that caused this AVC? Flash? 

If so, does flash work?

Comment 2 Tom 2010-11-15 15:20:34 UTC
Yes, using Flash, and it works. Not sure what's causing it, this is one of the many warnings I get at boot.

Comment 3 Daniel Walsh 2010-11-15 15:49:54 UTC
Turn on the boolean.

# setsebool -P user_direct_dri 1

Did you read the analysis?  Why did you think this needed to be reported as a bug?

Comment 4 Tom 2010-11-15 16:05:19 UTC
Didn't understand the warning
