Description Red Hat Case Diagnostics 2011-02-16 12:56:49 UTC

+++ This bug was initially created as a clone of Bug 543970 +++


Summary:

SELinux is preventing /usr/libexec/gdm-session-worker "write" access on /root.

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:

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
report.

Logging in directly as root from X Windows is not supported with SELinux,  It is considered too dangerous and the amount/type of policy that would needed to be written, would allow too much access.


Either put the machin in permissive mode when you login as root, or login as a normal user and use su or sudo to reach root.

Comment 3 Andrew Hecox 2011-02-16 13:53:19 UTC

Dan -- this looks like https://bugzilla.redhat.com/show_bug.cgi?id=674026 but it came through with a different hash. We're relying on the client-side hash: is there something different we should be doing?

Comment 4 Daniel Walsh 2011-02-16 19:53:43 UTC

The hash has changed since F12
