[PATCH net 0/6] pull request: fixes for ovpn 2026-04-17

[Antonio Quartulli <antonio@openvpn.net>]

Hi Jakub,

This is a respin of the PR I originally sent against net-next + an extra
fix (patch 6).

Please note that this patch:
https://lore.kernel.org/all/20260225010833.11301-1-liuhangbin@gmail.com/
broke the selftests entirely due to the switch from sh to bash.

There are new commits in the kselftest tree which take care of this:
https://lore.kernel.org/all/20260416-selftest-fix-readlink-e-v1-0-94e4cabbdec4@kernel.org/
but they are not in net yet, therefore you won't be able to test/run
our kselftests for now.

This being said...

TCP tests are still failing every now and then.
It seems that sometimes a single ping over a TCP tunnel is lost,
thus making the selftest fail.

We believe this is a bug in ovpn which we are currently hunting down.
So it's nothing wrong about the tests (they are actually doing their
job!).

Test hangs you reported on slow kernels are fixed.

See the tag content for a more detailed summary.
Please pull or let me know of any issue!

Thanks a lot,
	Antonio
