[PATCH 7/7] cifs: Always update signing key of first channel

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
