selftests: netdevsim: set test timeout to 10 minutes

2024-03-27T11:29:27+00:00

The longest running netdevsim test, nexthop.sh, currently takes
5 min to finish. Around 260s to be exact, and 310s on a debug kernel.
The default timeout in selftest is 45sec, so we need an explicit
config. Give ourselves some headroom and use 10min.

Commit under Fixes isn't really to "blame" but prior to that
netdevsim tests weren't integrated with kselftest infra
so blaming the tests themselves doesn't seem right, either.

selftests: netdevsim: be less selective for FW for the devlink test

2024-02-27T14:20:08+00:00

Commit 6151ff9c7521 ("selftests: netdevsim: use suitable existing dummy
file for flash test") introduced a nice trick to the devlink flashing
test. Instead of user having to create a file under /lib/firmware
we just pick the first one that already exists.

Sadly, in AWS Linux there are no files directly under /lib/firmware,
only in subdirectories. Don't limit the search to -maxdepth 1.
We can use the %P print format to get the correct path for files
inside subdirectories:

$ find /lib/firmware -type f -printf '%P\n' | head -1
intel-ucode/06-1a-05

The full path is /lib/firmware/intel-ucode/06-1a-05

This works in GNU find, busybox doesn't have printf at all,
so we're not making it worse.

selftests: netdevsim: fix the udp_tunnel_nic test

2024-01-24T23:11:10+00:00

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.

selftests: netdevsim: add a config file

2024-01-18T10:51:02+00:00

netdevsim tests aren't very well integrated with kselftest,
which has its advantages and disadvantages. But regardless
of the intended integration - a config file to know what kernel
to build is very useful, add one.
