Subject: [PATCH] smb3.1.1: enable negotiating stronger encryption by default
Git-commit: fee742b502894c8ed02506fff61d7605934f93cb
Patch-mainline: v5.13-rc1
References: bsc#1192606
Now that stronger encryption (gcm256) has been more broadly
tested, and confirmed to work with multiple servers (Windows
and Azure for example), enable it by default. Although gcm256 is
the second choice we offer (after gcm128 which should be faster),
this change allows mounts to server which are configured to
require the strongest encryption to work (without changing a module
load parameter).
