Description John Margaritopoulos 2011-08-14 14:57:34 UTC
SELinux is preventing /opt/google/chrome/chrome from 'execute_no_trans' accesses on the file /opt/google/chrome/chrome.

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

If you believe that chrome should be allowed execute_no_trans access on the chrome file 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

Comment 1 Daniel Walsh 2011-08-15 10:50:41 UTC
The sealert that tols you to relabel chrome to textrel_shlib_t was wrong.

Please change it back to the original label.

matchpathcon /opt/google/chrome/chrome
/opt/google/chrome/chrome	system_u:object_r:execmem_exec_t:s0


Then use audit2allow to add execmod permission to this executable.
