SMB1 callback get_cifs_acl_by_fid() currently ignores its last argument and
therefore ignores request for SACL_SECINFO. Fix this issue by correctly
propagating info argument from get_cifs_acl() and get_cifs_acl_by_fid() to
CIFSSMBGetCIFSACL() function and pass SACL_SECINFO when requested.
For accessing SACLs it is needed to open object with SYSTEM_SECURITY
access. Pass this flag when trying to get or set SACLs.
Same logic is in the SMB2+ code path.
This change fixes getting and setting of "system.cifs_ntsd_full" and
"system.smb3_ntsd_full" xattrs over SMB1 as currently it silentely ignored
SACL part of passed xattr buffer.

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.
