Subject: [PATCH net-next 00/10] ovpn: pull request for net-next: ovpn 2025-05-15

Hi Jakub,

this is a new version of the previous pull request.
These time I have removed the fixes that we are still discussing,
so that we don't hold the entire series back.

There is a new fix though: it's about properly checking the return value
of skb_to_sgvec_nomark(). I spotted the issue while testing pings larger
than the iface's MTU on a TCP VPN connection.

I have added various Closes and Link tags where applicable, so
that we have references to GitHub tickets and other public discussions.

Since I have resent the PR, I have also added Andrew's Reviewed-by to
the first patch.

Please pull or let me know if something should be changed!

Thanks a lot,
Antonio
