Description Brian Millett 2005-02-07 15:32:32 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5)
Gecko/20041228 Firefox/1.0 Fedora/1.0-8

Description of problem:
I am running rawhide, kernel 2.6.10-1.1126_FC4 and also 

When NetworkManager has made a connection, then when I try to stop
iptables (process 1), it hangs on "modprobe -r ip_tables".  If I stop
NetworkManager (process 2), then the "process 1" continues and stops.
 I can start and stop iptables as long as NetworkManager is stopped,
or has not yet made an active connection.  When I start NetworkManager
and make an active connection, I also can not start iptables.

Only message I get when I try to modprob -r ip_tables by hand when
NetworkManaager is working and active:

FATAL: Module ip_tables is in use. 

The behavior that is expected (start/stop iptables with active
NetworkManager connection) works for kernel 2.6.10-1.1115_FC4

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Have NetworkManager started and have an avtive connection
2. execute service iptables stop
3. wait forever

Actual Results:  system is hung waiting to terminate iptables.

Expected Results:  iptables should be terminated.

Additional info:

I can not really tell if this is a NetworkManager bug, but since it
works with other kernel revs, I think it is kernel related.
