Description Matthias Hölzl 2010-02-23 16:18:46 UTC
Summary:

SELinux is preventing /usr/sbin/modem-manager "getsched" access .

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by modem-manager. It is not expected that this
access is required by modem-manager 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://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Matthias Hölzl 2010-02-23 16:20:35 UTC
This denial seems to prevent Network Manager from establishing a wireless connection when SELinux is in enforcing mode.
