selftests: netdevsim: Fix ethtool-coalesce.sh fail by installing ethtool-common.sh

net: netdevsim: try to close UDP port harness races

[ Upstream commit 50bf398e1ceacb9a7f85bd3bdca065ebe5cb6159 ] syzbot discovered that we remove the debugfs files after we free the netdev.

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.

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.
