Freeze after putting up a GRE device with ip
Last modified: 2015-11-30 11:33:25 EST
Description of problem:
When creating a tunnel, the system freezes.
Version-Release number of selected component (if applicable):
Linux jezevec 4.2.5-201.fc22.x86_64 #1 SMP Wed Oct 28 20:00:23 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Steps to Reproduce:
$ sudo ip tun add tun0 mode gre remote `resolveip -s x.y.z.redhat.com` local A.B.C.D ttl 255
$ sudo ip a a 172.25.1.2/32 dev tun0
$ sudo ip l s dev tun0 up
Freeze, nothing in logs.
tunnel is doing it's tunneling stuff
I was able to reproduce two or three times in row and now I cannot.

again, but then It worked fine. I am still unsure what is different between the reproducing and not-reproducing steps I do.
