[PATCH net-next 0/5] pull request: ovpn 2026-09-22

[Antonio Quartulli <antonio@openvpn.net>]

Hi all!

Here is a small batch of ovpn changes for net-next, collected over the
past weeks. Most of it went through sashiko pre-review on openvpn-devel.

The bulk is cleanup: an unused work field goes away from struct
ovpn_socket, the redundant peer NULL checks in the crypto completion
helpers are dropped, and the documented return value of
ovpn_bind_from_sockaddr() is corrected.

On top of that, PEER_DEL_NTF now carries a peer snapshot in the same
format returned by PEER_GET. Userspace needs the final counters of a
disconnecting peer and so far had to issue a PEER_GET for every
notification; when many peers drop at once those extra transactions
overlap with notification processing on the same socket and can surface
transient netlink errors (peers disappear in the meantime). Carrying
the counters in the notification removes that round trip and errors.

Finally, the selftests enable TCP_NODELAY on ovpn-cli's TCP sockets, to
match what userspace does by default. Since TCP does not preserve record
boundaries, the capture-based peer ID check is restricted to UDP.

Note that the fixes I sent for net on Sep 21st ("pull request: fixes for
ovpn 2026-09-21") touch four of the same files, but the two series do
not conflict: I verified that they merge cleanly in either order and
that the resulting tree is identical both ways. The two pull requests
can therefore be merged in any order.

Please pull or let me know of any issue!

Thanks a lot,
	Antonio
