Subject: Re: [PATCH RFC net v3 4/7] net/iucv: factor out the HiperSockets frame dispatch and state changes
Date: Thu, 12 Nov 2026 04:44:41 +0000 [thread overview]
Message-ID: <sashiko-outbox-210386@kernel.org> (raw)
In-Reply-To: <20261110-b4-disp-2a6b4364-v3-4-35677b68e697@proton.me>

> Move the switch on the frame type out of afiucv_hs_rcv() into
> afiucv_hs_dispatch(), and the state changes a SYN|ACK, a SYN|FIN and a
> FIN make into afiucv_hs_synack(), afiucv_hs_synfin() and
> afiucv_hs_fin(). The three are still called under the bh_lock_sock() of
> their callbacks, which now test sk where they tested iucv_sk(sk), a
> cast of it. They are defined ahead of iucv_proto: the next patch
> reaches them from proto->release_cb. afiucv_hs_synfin() and
> afiucv_hs_fin() are the same for now and stay two: a later patch sets
> RCV_SHUTDOWN in the second only.
>
> No functional change. The next patch runs the dispatch from a second
> place and the three state changes from the task that owns the socket.
>
> Cc: stable@vger.kernel.org # 6.18.x, needed by the next patch
> Signed-off-by: Bryam Vargas <hexlabsecurity@proton.me>
