Description Bob hernandez 2009-12-15 00:49:06 UTC

SELinux is preventing /bin/bash "search" access on /home.

Detailed Description:

SELinux denied access requested by mysqld_safe. It is not expected that this
access is required by mysqld_safe and this access may signal an intrusion
attempt. It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug

Comment 1 Daniel Walsh 2009-12-15 14:06:21 UTC
You can add these rules for now using

# grep avc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
