Subject: [PATCH 1/7] cifs: do not send tree disconnect to ipc shares
Date: Fri,  4 Jun 2021 19:25:27 -0300	[thread overview]
Message-ID: <20210604222533.4760-2-pc@cjr.nz> (raw)
In-Reply-To: <20210604222533.4760-1-pc@cjr.nz>

On session close, the IPC is closed and the server must release all
tcons of the session.  It doesn't matter if we send a ipc close or
not.

Besides, it will make the server to not close durable and resilient
files on session close, as specified in MS-SMB2 3.3.5.6 Receiving an
SMB2 LOGOFF Request.
