Bug 70659

From Bugzilla Helper:
User-Agent: Mozilla/5.0 Galeon/1.2.0 (X11; Linux i686; U;) Gecko/20020509

Description of problem:
I use ip tunnels frequently, I call the devices (appropriately)
tunl0, tunl1, tunl2 and so on.
Hotplug goes berzerk trying to do something with them, and it can cause problems.

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


How reproducible:
Always

Steps to Reproduce:
1.Set up an ipip tunnel...
  modprobe ipip
  ip tunnel  add     tunl1 mode ipip local $LOCAL remote $REMOTE
  ip address add dev tunl1 $IPADDR peer $PEERIP
  ip link    set dev tunl1 up
2. The above is essentially what I have in a script I have made...
  /etc/sysconfig/network-script/ifup-tunl
  (Copy of this script is attached).
3. bad things can happen when I use this script...
	

Actual Results:  hotplug goes nuts unless "tunl" is added to /etc/hotplug/blacklist
when I attempt to bring up a tunnel device called "tunl"

Expected Results:  hotplug should not attempt to manage tunl, gre or any other
virtual network devices (such as dummy).

Additional info:

Please see attachment for my ifup-tunl script
(ok, it is messy, noisy and overly complex and
aggressively turns of firewall mods and so on.

Please see notes at the top of the script for further notes.

It works for me, it should work by default like any other
network device configured to be used with /sbin/ifup and family.
I have been using essentially the same script since rh62, and
hotplug has been the only real problem.
