Summary:

SELinux is preventing nm-system-setti (NetworkManager_t) "write" to ifcfg-eth0
(etc_t).

Detailed Description:

[SELinux is in permissive mode, the operation would have been denied but was
permitted due to permissive mode.]

SELinux is preventing nm-system-setti (NetworkManager_t) "write" to ifcfg-eth0
(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 (ifcfg-eth0) 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
'ifcfg-eth0'. 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 'ifcfg-eth0'

Fix Command:

restorecon 'ifcfg-eth0'
