Subject: [PATCH net 0/1] pull request: fixes for ovpn 2026-04-22
Date: Wed, 22 Apr 2026 14:32:41 +0200	[thread overview]
Message-ID: <20260422123242.530882-1-antonio@openvpn.net> (raw)

Hello netdev team,

This PR is a new version of the one sent on March 20th.
We are trying to address a remote, yet possible, race condition between
tearing down an ovpn interface and adding new peers via netlink.

After further discussion including Jakub and Sabrina, the following
patch came up.

It should address all raised concerns.
Sorry for taking so long to get back to this.

Please pull or let mw know of any issue!

Thanks a lot,
	Antonio
