Bug 585635

Résumé:

SELinux is preventing /usr/lib/chromium-browser/chrome-sandbox access to a
leaked fifo_file file descriptor.

Description détaillée:

[chrome-sandbox a un type permissif (chrome_sandbox_t). Cet accès n'a pas été
refusé.]

SELinux denied access requested by the chrome-sandbox command. It looks like
this is either a leaked descriptor or chrome-sandbox output was redirected to a
file it is not allowed to access. Leaks usually can be ignored since SELinux is
just closing the leak and reporting the error. The application does not use the
descriptor, so it will run properly. If this is a redirection, you will not get
output in the fifo_file. You should generate a bugzilla on selinux-policy, and
it will get routed to the appropriate package. You can safely ignore this avc.

Autoriser l'accès:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385)
