Subject: [PATCH v3 11/11] cifs: Always update signing key of first channel
Date: Tue, 26 Nov 2019 21:36:34 -0300 [thread overview]
Message-ID: <20191127003634.14072-12-pc@cjr.nz> (raw)
In-Reply-To: <20191127003634.14072-1-pc@cjr.nz>
Update signing key of first channel whenever generating the master
sigining/encryption/decryption keys rather than only in cifs_mount().
This also fixes reconnect when re-establishing smb sessions to other
servers.
