6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paolo Abeni <pabeni@xxxxxxxxxx>
[ Upstream commit e4e4b6d568d2549583cbda3f8ce567e586cb05da ]
The pmtu.sh test tries to detect the tunnel protocols available
in the running kernel and properly skip the unsupported cases.
In a few more complex setup, such detection is unsuccessful, as
the script currently ignores some intermediate error code at
setup time.
Before:
# which: no nettest in (/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin)
# TEST: vti6: PMTU exceptions (ESP-in-UDP) [FAIL]
# PMTU exception wasn't created after creating tunnel exceeding link layer MTU
# ./pmtu.sh: line 931: kill: (7543) - No such process
# ./pmtu.sh: line 931: kill: (7544) - No such process
After:
# xfrm4 not supported
# TEST: vti4: PMTU exceptions [SKIP]
Fixes: ece1278a9b81 ("selftests: net: add ESP-in-UDP PMTU test")
