cifs: Fix getting and setting SACLs over SMB1
[ Upstream commit 8b19dfb34d17e77a0809d433cc128b779282131b ]
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.
