Subject: [PATCH v13 net-next 12/23] net/tcp: Verify inbound TCP-AO signed segments
Date: Wed, 4 Oct 2023 23:36:16 +0100 [thread overview]
Message-ID: <20231004223629.166300-13-dima@arista.com> (raw)
In-Reply-To: <20231004223629.166300-1-dima@arista.com>
Now there is a common function to verify signature on TCP segments:
tcp_inbound_hash(). It has checks for all possible cross-interactions
with MD5 signs as well as with unsigned segments.
The rules from RFC5925 are:
(1) Any TCP segment can have at max only one signature.
(2) TCP connections can't switch between using TCP-MD5 and TCP-AO.
(3) TCP-AO connections can't stop using AO, as well as unsigned
connections can't suddenly start using AO.
