Subject: [RFC net-next 13/14] wireguard: netlink: enable strict genetlink validation
Date: Thu,  4 Sep 2025 22:02:47 +0000	[thread overview]
Message-ID: <20250904220255.1006675-13-ast@fiberby.net> (raw)
In-Reply-To: <20250904-wg-ynl-rfc@fiberby.net>

Wireguard is a modern enough genetlink family, that it doesn't
need resv_start_op. It already had policies in place when it was
first merged, it has also never used reserved fields, or other
things toggled by resv_start_op.

[TODO: before v1, also test with ancient wireguard-tools versions]
