Subject: [PATCH 2/2] iscsi_tcp: disallow binding the same connection twice
Date: Mon, 18 Mar 2024 12:49:02 -0700 [thread overview]
Message-ID: <20240318194902.3290795-2-khazhy@google.com> (raw)
In-Reply-To: <20240318194902.3290795-1-khazhy@google.com>
iscsi_sw_tcp_conn_bind does not check or cleanup previously bound
sockets, nor should we allow binding the same connection twice.
