Description Marc Wiriadisastra 2007-04-24 20:22:46 EDT
Description of problem:
I try to restart the network using either /etc/init.d/network restart or
service network restart as root

Version-Release number of selected component (if applicable):
SysVinit-2.86-16 [application]

How reproducible:

Every time I reboot the network.  Although I have set SELinux to Permissive.

Steps to Reproduce:
1. Restart the network
2. Have the settroubleshoot browser jump up with the error message
Additional Info:
I'll add the whole browser info for your viewing please :)

    SELinux is preventing /sbin/killall5 (dhcpc_t) "ptrace" to exe (initrc_t).

Detailed Description
    SELinux denied access requested by /sbin/killall5. It is not expected that
    this access is required by /sbin/killall5 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
    http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you can disable
    SELinux protection altogether. Disabling SELinux protection is not
    recommended. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi
    against this package.

Comment 1 Daniel Walsh 2007-04-25 11:02:19 EDT
Why are you running in permissive mode.  More avc messages are generated in
permissive mode, Since a prior dontaudit denial my have prevented this avc.  Do
you see this message when in enforcing mode?
Comment 2 Marc Wiriadisastra 2007-04-26 11:51:09 EDT
Just switched to enforcing and no I haven't come across it yet.

If I do I'll repost but at this point in time just mark it as not a bug if you can.
Comment 3 Daniel Walsh 2007-04-26 12:47:44 EDT
Reopen if you see a problem.
