[PATCH 6.7 205/346] selftests: netdevsim: fix the udp_tunnel_nic test

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jakub Kicinski <kuba@xxxxxxxxxx>

[ Upstream commit 0879020a7817e7ce636372c016b4528f541c9f4d ]

This test is missing a whole bunch of checks for interface
renaming and one ifup. Presumably it was only used on a system
with renaming disabled and NetworkManager running.

Fixes: 91f430b2c49d ("selftests: net: add a test for UDP tunnel info infra")
