Q: SELinux is preventing gdm-session-wor (xdm_t)

[neo_in_matrix]

I am running FC10 in VMware and keep getting this notification popup. Do I need to take some actions on this alert?

Or... I really want to suppress this alert, how can I do it?

Summary:

SELinux is preventing gdm-session-wor (xdm_t) "unlink" to ./.dmrc
(user_home_dir_t).

Detailed Description:

SELinux denied access requested by gdm-session-wor. It is not expected that this
access is required by gdm-session-wor 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:

Sometimes labeling problems can cause SELinux denials. You could try to restore
the default system file context for ./.dmrc,

restorecon -v './.dmrc'

If this does not work, there is currently no automatic way to allow this access.
Instead, you can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinu...fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

[domg472]

The file ~/.dmrc appears to have a wrong label. it should probably be "user_home_t"

Setroubleshoot suggested: /sbin/restorecon -v ~/.dmrc

This should solve this issue.

You might want to restorecon the context of the whole /home mountpoint:

/sbin/restorecon -R -v /home

Thanks.

Anyway, I disabled the setrouble service and I am not bothered any more.
