Description Matěj Cepl 2011-07-20 09:49:56 UTC
I am really not sure whether we want to support Google Chrome, but in case we want, I have this module to add.

SELinux is preventing /opt/google/chrome/chrome from 'use' accesses on the fd fd.
*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************

If you want to allow all domains to use other domains file descriptors
Then you must tell SELinux about this by enabling the 'allow_domain_fd_use' boolean.
Do
setsebool -P allow_domain_fd_use 1

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

If you believe that chrome should be allowed use access on the fd fd 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 chrome /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
