From 3f51d966f7bb987722e5b66fa97e7bbdf38c2cbb Mon Sep 17 00:00:00 2001 From: Paul Aurich Date: Fri, 26 Jun 2020 12:58:05 -0700 Subject: [PATCH] SMB3: Honor 'seal' flag for multiuser mounts commit cc15461c73d7d044d56c47e869a215e49bd429c8 upstream. Ensure multiuser SMB3 mounts use encryption for all users' tcons if the mount options are configured to require encryption. Without this, only the primary tcon and IPC tcons are guaranteed to be encrypted. Per-user tcons would only be encrypted if the server was configured to require encryption.
