[ovs-discuss] [RTSP, Patchport] Patch Port leads to crashing child if rstp is enabled

[Thomas Rosenstein]

Hi,

I just upgraded to 2.4.0 and enabled rstp, now adding a patch port leads 
to constant crashes of the child processes.

This only happens if BOTH ends of the patch have rstp enabled!

The commands:

ovs-vsctl add-br br-test1
ovs-vsctl add-br br-test2

ovs-vsctl set br br-test1 rstp_enable=true
ovs-vsctl set br br-test2 rstp_enable=true

ovs-vsctl add-port br-test1 patch-1-2
ovs-vsctl set interface patch-1-2 type=patch options:peer=patch-2-1

ovs-vsctl add-port br-test2 patch-2-1
ovs-vsctl set interface patch-2-1 type=patch options:peer=patch-1-2


The log file:
