Subject: Re: [PATCH net v2 3/5] vsock: Enforce no-transport invariant for TCP_LISTEN sockets
Date: Wed, 16 Sep 2026 13:15:59 +0000 [thread overview]
Message-ID: <20260916131600.000DA1F00893@smtp.kernel.org> (raw)
In-Reply-To: <20260915-vsock-connect-reset-closing-v2-3-a1d9abb472f7@rbox.co>
> A non-blocking connect() running in parallel with a blocking connect(),
> combined with a racy listen() that hits right after a connect timeout:
> TCP_SYN_SENT -> TCP_CLOSE -> TCP_LISTEN, while the connect() loop is still
> in progress.
>
> Enforce the invariant. Prevent a socket from becoming a listener after
> acquiring a transport.
>
> Fixes: c0cfa2d8a788 ("vsock: add multi-transports support")
> Signed-off-by: Michal Luczaj <mhal@rbox.co>
