0e29bc0eba selftests/vm: use top_srcdir instead of recomputing relative paths
In various places both in t/t/s/v/Makefile as well as some of the test
sources, we were referring to headers or directories using some fairly
long relative paths.

Since we have a working top_srcdir variable though, which refers to the
root of the kernel tree, we can clean up all of these "up and over"
relative paths, just relying on the single variable instead.

ccf22a48cc remoteproc: virtio: Fix warning on bindings by removing the of_match_table
The checkpatch tool complains that "virtio,rproc" is not documented.
But it is not possible to probe the device "rproc-virtio" by declaring
it in the device tree. So documenting it in the bindings does not make
sense.
This commit solves the checkpatch warning by suppressing the useless
of_match_table.

d2995249a2 arm64: alternatives: Use vdso/bits.h instead of linux/bits.h
When building with CONFIG_LTO after commit ba00c2a04f ("arm64: fix the
build with binutils 2.27"), the following build error occurs:

  In file included from arch/arm64/kernel/module-plts.c:6:

          ^

Similar to the issue resolved by commit 0072dc1b53 ("arm64: avoid
BUILD_BUG_ON() in alternative-macros"), there is a circular include
dependency through <linux/bits.h> when CONFIG_LTO is enabled due to
<asm/rwonce.h> appearing in the include chain before the contents of
<asm/alternative-macros.h>, which results in ALTERNATIVE() not getting
expanded properly because it has not been defined yet.

Avoid this issue by including <vdso/bits.h>, which includes the
definition of the BIT() macro, instead of <linux/bits.h>, as BIT() is the
only macro from bits.h that is relevant to this header.

f5ba1cdaf5 ksmbd: validate share name from share config response
Share config response may contain the share name without casefolding as
it is known to the user space daemon. When it is present, casefold and
compare it to the share name the share config request was made with. If
they differ, we have a share config which is incompatible with the way
share config caching is done. This is the case when CONFIG_UNICODE is
not set, the share name contains non-ASCII characters, and those non-
ASCII characters do not match those in the share name known to user
space. In other words, when CONFIG_UNICODE is not set, UTF-8 share
names now work but are only case-insensitive in the ASCII range.

dbab80e207 ksmbd: make utf-8 file name comparison work in __caseless_lookup()
Case-insensitive file name lookups with __caseless_lookup() use
strncasecmp() for file name comparison. strncasecmp() assumes an
ISO8859-1-compatible encoding, which is not the case here as UTF-8
is always used. As such, use of strncasecmp() here produces correct
results only if both strings use characters in the ASCII range only.
Fix this by using utf8_strncasecmp() if CONFIG_UNICODE is set. On
failure or if CONFIG_UNICODE is not set, fallback to strncasecmp().
Also, as we are adding an include for `linux/unicode.h', include it
in `fs/ksmbd/connection.h' as well since it should be explicit there.

7c88c1e0ab ksmbd: Fix user namespace mapping
A kernel daemon should not rely on the current thread, which is unknown
and might be malicious.  Before this security fix,
ksmbd_override_fsids() didn't correctly override FS UID/GID which means
that arbitrary user space threads could trick the kernel to impersonate
arbitrary users or groups for file system access checks, leading to
file system access bypass.

This was found while investigating truncate support for Landlock:

78af146e10 ksmbd: reduce server smbdirect max send/receive segment sizes
Reduce ksmbd smbdirect max segment send and receive size to 1364
to match protocol norms. Larger buffers are unnecessary and add
significant memory overhead.

2b4eeeaa90 ksmbd: decrease the number of SMB3 smbdirect server SGEs
The server-side SMBDirect layer requires no more than 6 send SGEs
The previous default of 8 causes ksmbd to fail on the SoftiWARP
(siw) provider, and possibly others. Additionally, large numbers
of SGEs reduces performance significantly on adapter implementations.

b1763d265a ksmbd: Fix wrong return value and message length check in smb2_ioctl()
Commit c7803b05f7 ("smb3: fix ksmbd bigendian bug in oplock
break, and move its struct to smbfs_common") use the defination
of 'struct validate_negotiate_info_req' in smbfs_common, the
array length of 'Dialects' changed from 1 to 4, but the protocol
does not require the client to send all 4. This lead the request
which satisfied with protocol and server to fail.

So just ensure the request payload has the 'DialectCount' in
smb2_ioctl(), then fsctl_validate_negotiate_info() will use it
to validate the payload length and each dialect.

Also when the {in, out}_buf_len is less than the required, should
goto out to initialize the status in the response header.

af705ef2b0 ksmbd: fix encryption failure issue for session logoff response
If client send encrypted session logoff request on seal mount,
Encryption for that response fails.

ksmbd: Could not get encryption key
CIFS: VFS: cifs_put_smb_ses: Session Logoff failure rc=-512

Session lookup fails in ksmbd_get_encryption_key() because sess->state is
set to SMB2_SESSION_EXPIRED in session logoff. There is no need to do
session lookup again to encrypt the response. This patch change to use
ksmbd_session in ksmbd_work.

16b5f54e30 ksmbd: casefold utf-8 share names and fix ascii lowercase conversion
strtolower() corrupts all UTF-8 share names that have a byte in the C0
(À ISO8859-1) to DE (Þ ISO8859-1) range, since the non-ASCII part of
ISO8859-1 is incompatible with UTF-8. Prevent this by checking that a
byte is in the ASCII range with isascii(), before the conversion to
lowercase with tolower(). Properly handle case-insensitivity of UTF-8
share names by casefolding them, but fallback to ASCII lowercase
conversion on failure or if CONFIG_UNICODE is not set. Refactor to move
the share name casefolding immediately after the share name extraction.
Also, make the associated constness corrections.

276a3f7cf1 ksmbd: port to vfs{g,u}id_t and associated helpers
A while ago we introduced a dedicated vfs{g,u}id_t type in commit
1e5267cd08 ("mnt_idmapping: add vfs{g,u}id_t"). We already switched
over a good part of the VFS. Ultimately we will remove all legacy
idmapped mount helpers that operate only on k{g,u}id_t in favor of the
new type safe helpers that operate on vfs{g,u}id_t.

88541cb414 ksmbd: fix incorrect handling of iterate_dir
if iterate_dir() returns non-negative value, caller has to treat it
as normal and check there is any error while populating dentry
information. ksmbd doesn't have to do anything because ksmbd already
checks too small OutputBufferLength to store one file information.

And because ctx->pos is set to file->f_pos when iterative_dir is called,
remove restart_ctx(). And if iterate_dir() return -EIO, which mean
directory entry is corrupted, return STATUS_FILE_CORRUPT_ERROR error
response.

This patch fixes some failure of SMB2_QUERY_DIRECTORY, which happens when
ntfs3 is local filesystem.
