commit 1b5487aefb1ce7a6b1f15a33297d1231306b4122 upstream. Setting encryption as required in security flags was broken. For example (to require all mounts to be encrypted by setting): "echo 0x400c5 > /proc/fs/cifs/SecurityFlags" Would return "Invalid argument" and log "Unsupported security flags" This patch fixes that (e.g. allowing overriding the default for SecurityFlags 0x00c5, including 0x40000 to require seal, ie SMB3.1.1 encryption) so now that works and forces encryption on subsequent mounts.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
