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.

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:

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.

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

patches fix serious problems, for example, i.MX has an issue where
changing the NAND clk frequency hangs the system. On Allwinner H6 the
GPU is being overclocked which could lead to long term hardware damage.
And finally on some Broadcom SoCs the serial console stopped working
because the clk tree hierarchy description got broken by an inadvertant
DT node name change. That's fixed by using 'clock-output-names' to
generate a stable and unique name for clks so the framework can properly
link things up.
There's also a couple build fixes in here. One to fix CONFIG_OF=n builds
and one to avoid an array out of bounds bug that happens during clk
registration on microchip. I hope that KASAN would have found that OOB
problem, but probably KASAN wasn't attempted. Instead LLVM/clang
compilation caused an oops, while GCC didn't.

Pull clk driver fixes from Stephen Boyd:
"Here's the last batch of clk driver fixes for this release.
These patches fix serious problems, for example, i.MX has an issue
where changing the NAND clk frequency hangs the system. On Allwinner
H6 the GPU is being overclocked which could lead to long term hardware
damage.
And finally on some Broadcom SoCs the serial console stopped working
because the clk tree hierarchy description got broken by an
inadvertant DT node name change. That's fixed by using
'clock-output-names' to generate a stable and unique name for clks so
the framework can properly link things up.
There's also a couple build fixes in here. One to fix CONFIG_OF=n
builds and one to avoid an array out of bounds bug that happens during
clk registration on microchip. I hope that KASAN would have found that
OOB problem, but probably KASAN wasn't attempted. Instead LLVM/clang
compilation caused an oops, while GCC didn't"

clk: imx93: drop of_match_ptr
clk: iproc: Do not rely on node name for correct PLL setup
clk: sunxi-ng: h6: Fix default PLL GPU rate
clk: imx: imx6sx: remove the SET_RATE_PARENT flag for QSPI clocks
clk: microchip: mpfs: make the rtc's ahb clock critical
clk: microchip: mpfs: fix clk_cfg array bounds violation
clk: ingenic-tcu: Properly enable registers before accessing timers
- Fail the 'perf test record' entry on error, fixing a regression where just
setup stuff like allocating memory and not the actual things being tested failed.
- Fixup disabling of -Wdeprecated-declarations for the python scripting engine, the
previous attempt had a brown paper bag thinko.
- Fix branch stack sampling test to include sanity check for branch filter on PowerPC.
- Update is_ignored_symbol function to match the kernel ignored list, fixing running
the 'perf test' entry that compares resolving symbols from kallsyms to resolving from
vmlinux.
- Augment the data source type with ARM's neoverse_spe list, the previous code
was limited in its search resolving the data source.
- Fix some clang 5 variable set but unused cases.
- Get a perf cgroup more portably in BPF as the __builtin_preserve_enum_value builtin is
not available in older versions of clang. In those cases we can forgo BPF's CO-RE (Compile
Once, Run Everywhere).
- More Fixes for Intel's hybrid CPU model.
