Description Dimitri Papadopoulos 2016-09-10 19:28:41 UTC 
Description of problem:
SELinux is preventing ps from 'sys_ptrace' accesses on the cap_userns Unknown.

*****  Plugin mozplugger (99.1 confidence) suggests   ************************

If vous voulez utiliser le paquet plugin
Then vous devez désactiver les contrôles SELinux sur les extensions Firefox.
Do
# setsebool -P unconfined_mozilla_plugin_transition 0

*****  Plugin catchall (1.81 confidence) suggests   **************************

If vous pensez que ps devrait être autorisé à accéder sys_ptrace sur Unknown cap_userns par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
Do
allow this access for now by executing:
# ausearch -c 'ps' --raw | audit2allow -M my-ps
# semodule -X 300 -i my-ps.pp
