Description Filip Pokryvka 2021-03-31 15:22:50 UTC

Description of problem:
When NetworkManager is configured to create autoconnections when device gets created, it does not delete the connection when device is removed via 'ip link del'

Version-Release number of selected component (if applicable):
1.32.0-0.1.el8

How reproducible:
always

Steps to Reproduce:
 1. ensure autoconnections for veths are allowed via udev and my_veth* is allowed in NetworkManager config, see allow_veth_connections_bs in https://gitlab.freedesktop.org/NetworkManager/NetworkManager-ci/-/blob/master/nmci/tags.py
 2. add veth pair:
     ip l add my_veth1 type veth peer name my_veth1p
     ip l set my_veth1 up
     ip l set my_veth1p up
 3. check "Wired connection 1" exists
     nmcli c
 4. delete veth pair 
     ip l del my_veth1

Actual results:
autoconnection "Wired connection 1" is not deleted

Expected results:
autoconnection should be deleted

Additional info:
covered by NetworkManager-ci test: nmcli/runtest.sh stable_mem_consuption2
