Description sunminlei 2010-06-28 15:22:20 UTC

SELinux is preventing /usr/sbin/NetworkManager "write" access on

Detailed Description:

SELinux denied access requested by NetworkManager. It is not expected that this
access is required by NetworkManager 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

Hash String generated from  selinux-policy-3.6.32-116.fc12,catchall,NetworkManager,NetworkManager_t,var_lib_t,dir,write
audit2allow suggests:

#============= NetworkManager_t ==============
#!!!! The source type 'NetworkManager_t' can write to a 'dir' of the following types:
# etc_t, var_run_t, NetworkManager_log_t, dhcpc_state_t, var_log_t, NetworkManager_var_lib_t, NetworkManager_var_run_t, net_conf_t, dnsmasq_var_run_t, tmp_t, named_cache_t, NetworkManager_tmp_t, root_t

allow NetworkManager_t var_lib_t:dir write;

You have a labeling problem. Execute:

restorecon -R -v /var/lib/NetworkManager

Will fix.
