:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that chrome-sandbox should be allowed ptrace access on processes labeled chrome_sandbox_t 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-sandbox /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Daniel Walsh 2011-11-23 15:00:44 UTC
Miroslav we should just allow this in F16, and deny it in F17.  Hopefully the kernel will stop reporting bogus ptrace avcs.
