Subject: [PATCH AUTOSEL 5.10 09/33] net: correct sk_acceptq_is_full()
Date: Mon, 29 Mar 2021 18:21:57 -0400 [thread overview]
Message-ID: <20210329222222.2382987-9-sashal@kernel.org> (raw)
In-Reply-To: <20210329222222.2382987-1-sashal@kernel.org>
From: liuyacan <yacanliu@163.com>
[ Upstream commit f211ac154577ec9ccf07c15f18a6abf0d9bdb4ab ]
The "backlog" argument in listen() specifies
the maximom length of pending connections,
so the accept queue should be considered full
if there are exactly "backlog" elements.
