Even though it is unlikely to ever make a difference, let's use u32
consistently for the size of the load_options provided by the firmware
(aka the command line)
While at it, do some general cleanup too: use efi_char16_t, avoid using
options_chars in places where it really means options_size, etc.

Fuzzers like to scribble over sb_bsize_shift but in reality it's very
unlikely that this field would be corrupted on its own. Nevertheless it
should be checked to avoid the possibility of messy mount errors due to
bad calculations. It's always a fixed value based on the block size so
we can just check that it's the expected value.
Tested with:
mkfs.gfs2 -O -p lock_nolock /dev/vdb
for i in 0 -1 64 65 32 33; do
gfs2_edit -p sb field sb_bsize_shift $i /dev/vdb
mount /dev/vdb /mnt/test && umount /mnt/test
done
Before this patch we get a withdraw after
[ 76.413681] gfs2: fsid=loop0.0: fatal: invalid metadata block
[ 76.413681] bh = 19 (type: exp=5, found=4)
[ 76.413681] function = gfs2_meta_buffer, file = fs/gfs2/meta_io.c, line = 492
and with UBSAN configured we also get complaints like

[ 76.373815] shift exponent 4294967287 is too large for 64-bit type 'long unsigned int'
After the patch, these complaints don't appear, mount fails immediately
and we get an explanation in dmesg.

Merge series from Martin Povišer <povik+lin@cutebit.org>:
there's a CS42L83 headphone jack codec found in Apple computers (in the
recent 'Apple Silicon' ones as well as in earlier models, one example
[1]). The part isn't publicly documented, but it appears almost
identical to CS42L42, for which we have a driver in kernel. This series
adapts the CS42L42 driver to the new part, and makes one change in
anticipation of a machine driver for the Apple computers.
Patch 1 adds new compatible to the cs42l42 schema.
Patches 2 to 7 are taken from Richard's recent series [2] adding
soundwire support to cs42l42. They are useful refactorings to build on
in the later patches, and also this way our work doesn't diverge.
(I fixed missing free_irq path in cs42l42_init, did
s/Soundwire/SoundWire/ in changelogs, rebased.)
Patch 8 exports some regmap-related symbols from cs42l42.c so they can
be used to create cs42l83 regmap in cs42l83-i2c.c later.
Patch 9 is the cs42l83 support proper.
Patch 10 implements 'set_bclk_ratio' on the cs42l42 core. This will be
called by the upcoming ASoC machine driver for 'Apple Silicon' Macs.
(We have touched on this change to be made in earlier discussion, see
[3] and replies.)
Patch 11 brings cs42l42-i2c.c in sync with cs42l83-i2c.c on
dev_err_probe() usage.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
This patchset solves a known issue with ES8336 platforms wrt MCLK
selection. Most of the devices use the MCLK0 signal, but some devices
do use the MCLK1 signal.
The MCLK is defined in the topology, it would be a nightmare to
generate more topology files just for one MCLK difference. With a
minor extension to the intel-nhlt library, the MCLK information can be
found by parsing the NHLT table, and we can override the mclk_id at
boot time.
The only known issues for this platform remain the detection of GPIO
and microphone connections, currently only possible with manual
quirks.
Thanks to Eugene J. Markow for testing this patchset.

SOF topologies hard-code the MCLK used for SSP connections. That was a
bad idea in hindsight, this information should really come from BIOS
and/or machine driver.
This patch introduces a helper to scan all SSP endpoints connected to
a codec, and all formats to see what MCLK is used. When BIT(0) of the
mdivc offset if set in the SSP blob, MCLK0 is used, and likewise when
BIT(1) is set MCLK1 is used.
The case where both MCLKs are used is possible but has never been seen
in practice so should be treated as an error by the caller.

The Topre REALFORCE R2 firmware incorrectly reports that interface
descriptor number 1, input report descriptor 2's events are array events
rather than variable events. That particular report descriptor is used
to report keypresses when there are more than 6 keys held at a time.
This bug prevents events from this interface from being registered
properly, so only 6 keypresses (from a different interface) can be
registered at once, rather than full n-key rollover.
This commit fixes the bug by setting the correct value in a report_fixup
function.

Andrea Mayer says:
====================
seg6: add NEXT-C-SID support for SRv6 End behavior
The Segment Routing (SR) architecture is based on loose source routing.
A list of instructions, called segments, can be added to the packet headers to
influence the forwarding and processing of the packets in an SR enabled
network.
In SRv6 (Segment Routing over IPv6 data plane) [1], the segment identifiers
(SIDs) are IPv6 addresses (128 bits) and the segment list (SID List) is carried
in the Segment Routing Header (SRH). A segment may correspond to a "behavior"
that is executed by a node when the packet is received.
The Linux kernel currently supports a large subset of the behaviors described
in [2] (e.g., End, End.X, End.T and so on).
Some SRv6 scenarios (i.e.: traffic-engineering, fast-rerouting, VPN, mobile
network backhaul, etc.) may require a large number of segments (i.e. up to 15).
Therefore, reducing the size of the SID List is useful to minimize the impact
on MTU (Maximum Transfer Unit) and to enable SRv6 on legacy hardware devices
with limited processing power that can suffer from long IPv6 headers.
Draft-ietf-spring-srv6-srh-compression [3] extends the SRv6 architecture by
providing different mechanisms for the efficient representation (i.e.
compression) of the SID List.
The NEXT-C-SID mechanism described in [3] offers the possibility of encoding
several SRv6 segments within a single 128 bit SID address. Such a SID address
is called a Compressed SID Container. In this way, the length of the SID List
can be drastically reduced. In some cases, the SRH can be omitted, as the IPv6
Destination Address can carry the whole Segment List, using its compressed
representation.
The NEXT-C-SID mechanism relies on the "flavors" framework defined in [2].
The flavors represent additional operations that can modify or extend a subset
of the existing behaviors.
In this patchset we extend the SRv6 Subsystem in order to support the
NEXT-C-SID mechanism.
In details the patchset is made of:
- patch 1/3: add netlink_ext_ack support in parsing SRv6 behavior attributes;
- patch 2/3: add NEXT-C-SID support for SRv6 End behavior;
- patch 3/3: add selftest for NEXT-C-SID in SRv6 End behavior.
The corresponding iproute2 patch for supporting the NEXT-C-SID in SRv6 End
behavior is provided in a separated patchset.
Comments, improvements and suggestions are always appreciated.

This selftest is designed for testing the support of NEXT-C-SID flavor
for SRv6 End behavior. It instantiates a virtual network composed of
several nodes: hosts and SRv6 routers. Each node is realized using a
network namespace that is properly interconnected to others through veth
pairs.
The test considers SRv6 routers implementing IPv4/IPv6 L3 VPNs leveraged
by hosts for communicating with each other. Such routers i) apply
different SRv6 Policies to the traffic received from connected hosts,
considering the IPv4 or IPv6 protocols; ii) use the NEXT-C-SID
compression mechanism for encoding several SRv6 segments within a single
128-bit SID address, referred to as a Compressed SID (C-SID) container.
The NEXT-C-SID is provided as a "flavor" of the SRv6 End behavior,
enabling it to properly process the C-SID containers. The correct
execution of the enabled NEXT-C-SID SRv6 End behavior is verified
through reachability tests carried out between hosts belonging to the
same VPN.

The NEXT-C-SID mechanism described in [1] offers the possibility of
encoding several SRv6 segments within a single 128 bit SID address. Such
a SID address is called a Compressed SID (C-SID) container. In this way,
the length of the SID List can be drastically reduced.
A SID instantiated with the NEXT-C-SID flavor considers an IPv6 address
logically structured in three main blocks: i) Locator-Block; ii)
Locator-Node Function; iii) Argument.
C-SID container
+------------------------------------------------------------------+
| Locator-Block |Loc-Node| Argument |
| |Function| |
+------------------------------------------------------------------+
<--------- B -----------> <- NF -> <------------- A --------------->
(i) The Locator-Block can be any IPv6 prefix available to the provider;
(ii) The Locator-Node Function represents the node and the function to
be triggered when a packet is received on the node;
(iii) The Argument carries the remaining C-SIDs in the current C-SID
container.
The NEXT-C-SID mechanism relies on the "flavors" framework defined in
[2]. The flavors represent additional operations that can modify or
extend a subset of the existing behaviors.
This patch introduces the support for flavors in SRv6 End behavior
implementing the NEXT-C-SID one. An SRv6 End behavior with NEXT-C-SID
flavor works as an End behavior but it is capable of processing the
compressed SID List encoded in C-SID containers.
An SRv6 End behavior with NEXT-C-SID flavor can be configured to support
user-provided Locator-Block and Locator-Node Function lengths. In this
implementation, such lengths must be evenly divisible by 8 (i.e. must be
byte-aligned), otherwise the kernel informs the user about invalid
values with a meaningful error code and message through netlink_ext_ack.
If Locator-Block and/or Locator-Node Function lengths are not provided
by the user during configuration of an SRv6 End behavior instance with
NEXT-C-SID flavor, the kernel will choose their default values i.e.,
32-bit Locator-Block and 16-bit Locator-Node Function.

An SRv6 behavior instance can be set up using mandatory and/or optional
attributes.
In the setup phase, each supplied attribute is parsed and processed. If
the parsing operation fails, the creation of the behavior instance stops
and an error number/code is reported to the user. In many cases, it is
challenging for the user to figure out exactly what happened by relying
only on the error code.
For this reason, we add the support for netlink_ext_ack in parsing SRv6
behavior attributes. In this way, when an SRv6 behavior attribute is
parsed and an error occurs, the kernel can send a message to the
userspace describing the error through a meaningful text message in
addition to the classic error code.

Currently ib_copy_from_udata and ib_copy_to_udata could underfill
the request and response buffer if the user-space passes an undersized
value for udata->inlen or udata->outlen respectively [1]
This could lead to undesirable behavior.
Zero initing the buffer only goes as far as preventing using the buffer
uninitialized.
Validate udata->inlen and udata->outlen passed from user-space to ensure
they are at least the required minimum size.

Rather than relying on a never-ending stream of patches for quirks.
This change will detect whether HID++ 1.0 hi-res scroll, HID++ 2.0
hi-res scroll or HID++ 2.0 hi-res scroll wheel is supported, and enable
the feature without the need for quirks.
Tested on a Logitech M705 mouse that was unsupported before this change.

Maximum frame length check is enabled in lan937x switch on POR, But it
is found to be disabled on driver during port setup operation. Due to
this, packets are not dropped when transmitted with greater than configured
value. For testing, setup made for lan1->lan2 transmission and configured
lan1 interface with a frame length (less than 1500 as mentioned in
documentation) and transmitted packets with greater than configured value.
Expected no packets at lan2 end, but packets observed at lan2.
Based on the documentation, packets should get discarded if the actual
packet length doesn't match the frame length configured. Frame length check
should be disabled only for cascaded ports due to tailtags.
This feature was disabled on ksz9477 series due to ptp issue, which is
not in lan937x series. But since lan937x took ksz9477 as base, frame
length check disabled here as well. Patch added to remove this portion
from port setup so that maximum frame length check will be active for
normal ports.

Beginning of the merge window we introduced the vfs{g,u}id_t types in
b27c82e12965 ("attr: port attribute changes to new types") and changed
various codepaths over including chown_common().
During that change we forgot to account for the case were the passed
ownership value is -1. In this case the ownership fields in struct iattr
aren't initialized but we rely on them being initialized by the time we
generate the ownership to pass down to the LSMs. All the major LSMs
don't care about the ownership values at all. Only Tomoyo uses them and
so it took a while for syzbot to unearth this issue.
Fix this by initializing the ownership fields and do it within the
retry_deleg block. While notify_change() doesn't alter the ownership
fields currently we shouldn't rely on it.
Since no kernel has been released with these changes this does not
needed to be backported to any stable kernels.
