Subject: Linux counter_validate() RFC6479 replay detection modifies bitmap before authentication?
Date: Thu, 20 Apr 2023 21:58:46 +0200 [thread overview]
Message-ID: <CAMjhiJimUHUVjTybh0kfMUWHgVv0n7qJKQU+Ac3kabdtdRMt3Q@mail.gmail.com> (raw)
Hello all,
I am trying to understand a few details in WireGuard protocol, looking
at the Linux kernel WireGuard implementation if I am unsure about the
description from the paper. One question I have:
Does counter_validate() in the receive path update the bitmap from the
Type 4 counter (their_counter) before the received Type 4 packet was
authenticated?
Regards,
Leon.
