Subject: Re: [RFC v1 4/4] nvmet-discovery: do not use invalid port
Date: Wed, 13 Sep 2023 13:35:19 +0200	[thread overview]
Message-ID: <20230913113519.GA1565@lst.de> (raw)
In-Reply-To: <pzgeaisqmqz5up5fiorl46lmb6xglpdu4hp5lxotclnzvpfjrj@mgyfvcrvpl4x>

So that's interesting.  But what I'm mostly worried about is how the
nvmet kernel code allows a request without ->port to progress to the
actual command handler.  We should never allow a command to get that
far if ->port is NULL, and should not allow to clear ->port while
commands are still handled.
