:SELinux is preventing chrome from using the 'ptrace' accesses on a process.

:*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************
:
:If you want to allow sysadm to debug or ptrace all processes.
:Then you must tell SELinux about this by enabling the 'deny_ptrace'boolean.
:Do
:setsebool -P deny_ptrace 0
:
:*****  Plugin catchall (11.6 confidence) suggests  ***************************
:
:If you believe that chrome should be allowed ptrace access on processes labeled unconfined_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 /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Daniel Walsh 2012-03-17 10:34:56 UTC
This is a kernel issue that we hope to resolve soon. allowing processes to ptrace their children.

Comment 2 Daniel Walsh 2012-03-19 14:47:17 UTC
This bug would probably be fixed by the fix for this bug.
