Bug 546969

Summary:

SELinux is preventing nm-system-setti (NetworkManager_t) "unlink" to
/etc/NetworkManager/nm-system-settings.conf (etc_t).

Detailed Description:

SELinux is preventing nm-system-setti (NetworkManager_t) "unlink" to
/etc/NetworkManager/nm-system-settings.conf (etc_t). The SELinux type etc_t, is
a generic type for all files in the directory and very few processes (SELinux
Domains) are allowed to write to this SELinux type. This type of denial usual
indicates a mislabeled file. By default a file created in a directory has the
gets the context of the parent directory, but SELinux policy has rules about the
creation of directories, that say if a process running in one SELinux Domain
(D1) creates a file in a directory with a particular SELinux File Context (F1)
the file gets a different File Context (F2). The policy usually allows the
SELinux Domain (D1) the ability to write, unlink, and append on (F2). But if for
some reason a file (/etc/NetworkManager/nm-system-settings.conf) was created
with the wrong context, this domain will be denied. The usual solution to this
problem is to reset the file context on the target file, restorecon -v
'/etc/NetworkManager/nm-system-settings.conf'. If the file context does not
change from etc_t, then this is probably a bug in policy. Please file a bug
report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against the
selinux-policy package. If it does change, you can try your application again to
see if it works. The file context could have been mislabeled by editing the file
or moving the file from a different directory, if the file keeps getting
mislabeled, check the init scripts to see if they are doing something to
mislabel the file.

Allowing Access:

You can attempt to fix file context by executing restorecon -v
'/etc/NetworkManager/nm-system-settings.conf'

Fix Command:

restorecon '/etc/NetworkManager/nm-system-settings.conf'
