commit 57e4a9bd61c308f607bc3e55e8fa02257b06b552 upstream.

MS-SMB2 section 2.2.13.2.10 specifies that 'epoch' should be a 16-bit
unsigned integer used to track lease state changes. Change the data
type of all instances of 'epoch' from unsigned int to __u16. This
simplifies the epoch change comparisons and makes the code more
compliant with the protocol spec.

cifs: Fix parsing reparse point with native symlink in SMB1 non-UNICODE session

[ Upstream commit f4ca4f5a36eac9b4da378a0f28cbbe38534a0901 ]

SMB1 NT_TRANSACT_IOCTL/FSCTL_GET_REPARSE_POINT even in non-UNICODE mode
returns reparse buffer in UNICODE/UTF-16 format.

This is because FSCTL_GET_REPARSE_POINT is NT-based IOCTL which does not
distinguish between 8-bit non-UNICODE and 16-bit UNICODE modes and its path
buffers are always encoded in UTF-16.

This change fixes reading of native symlinks in SMB1 when UNICODE session
is not active.

cifs: Fix parsing native symlinks relative to the export

cifs: Fix parsing native symlinks relative to the export

[ Upstream commit 723f4ef90452aa629f3d923e92e0449d69362b1d ]

SMB symlink which has SYMLINK_FLAG_RELATIVE set is relative (as opposite of
the absolute) and it can be relative either to the current directory (where
is the symlink stored) or relative to the top level export path. To what it
is relative depends on the first character of the symlink target path.

If the first character is path separator then symlink is relative to the
export, otherwise to the current directory. Linux (and generally POSIX
systems) supports only symlink paths relative to the current directory
where is symlink stored.

Currently if Linux SMB client reads relative SMB symlink with first
character as path separator (slash), it let as is. Which means that Linux
interpret it as absolute symlink pointing from the root (/). But this
location is different than the top level directory of SMB export (unless
SMB export was mounted to the root) and thefore SMB symlinks relative to
the export are interpreted wrongly by Linux SMB client.

Fix this problem. As Linux does not have equivalent of the path relative to
the top of the mount point, convert such symlink target path relative to
the current directory. Do this by prepending "../" pattern N times before
the SMB target path, where N is the number of path separators found in SMB
symlink path.

So for example, if SMB share is mounted to Linux path /mnt/share/, symlink
is stored in file /mnt/share/test/folder1/symlink (so SMB symlink path is
test\folder1\symlink) and SMB symlink target points to \test\folder2\file,
then convert symlink target path to Linux path ../../test/folder2/file.

Deduplicate code for parsing SMB symlinks in native form from functions
smb2_parse_symlink_response() and parse_reparse_native_symlink() into new
function smb2_parse_native_symlink() and pass into this new function a new
full_path parameter from callers, which specify SMB full path where is
symlink stored.

This change fixes resolving of the native Windows symlinks relative to the
top level directory of the SMB share.

smb: client: use actual path when queryfs

commit a421e3fe0e6abe27395078f4f0cec5daf466caea upstream.

Due to server permission control, the client does not have access to
the shared root directory, but can access subdirectories normally, so
users usually mount the shared subdirectories directly. In this case,
queryfs should use the actual path instead of the root directory to
avoid the call returning an error (EACCES).

smb: client: set correct file type from NFS reparse points

Handle all file types in NFS reparse points as specified in MS-FSCC
2.1.2.6 Network File System (NFS) Reparse Data Buffer.

The client is now able to set all file types based on the parsed NFS
reparse point, which used to support only symlinks. This works for
SMB1+.
