bf8acc9e10 ksmbd: improve credits management
* Requests except READ, WRITE, IOCTL, INFO, QUERY
DIRECOTRY, CANCEL must consume one credit.
* If client's granted credits are insufficient,
refuse to handle requests.
* Windows server 2016 or later grant up to 8192
credits to clients at once.

f7db8fd03a ksmbd: add validation in smb2_ioctl
Add validation for request/response buffer size check in smb2_ioctl and
fsctl_copychunk() take copychunk_ioctl_req pointer and the other arguments
instead of smb2_ioctl_req structure and remove an unused smb2_ioctl_req
argument of fsctl_validate_negotiate_info.

776c750108 ata: ahci_platform: fix null-ptr-deref in ahci_platform_enable_regulators()
I got a null-ptr-deref report:

KASAN: null-ptr-deref in range [0x0000000000000090-0x0000000000000097]
...
RIP: 0010:regulator_enable+0x84/0x260

If devm_regulator_get() in ahci_platform_get_resources() fails,
hpriv->phy_regulator will point to NULL, when enabling or disabling it,
null-ptr-deref will occur.

ahci_probe()
	ahci_platform_get_resources()
		devm_regulator_get(, "phy") // failed, let phy_regulator = NULL
	ahci_platform_enable_resources()
		ahci_platform_enable_regulators()
			regulator_enable(hpriv->phy_regulator) // null-ptr-deref

commit 962399bb7f ("ata: libahci_platform: Fix regulator_get_optional()
misuse") replaces devm_regulator_get_optional() with devm_regulator_get(),
but PHY regulator omits to delete "hpriv->phy_regulator = NULL;" like AHCI.
Delete it like AHCI regulator to fix this bug.

43fc10c187 drm/amdkfd: unregistered svm range not overlap with TTM range
When creating unregistered new svm range to recover retry fault, avoid
new svm range to overlap with ranges or userptr ranges managed by TTM,
otherwise svm migration will trigger TTM or userptr eviction, to evict
user queues unexpectedly.

Change helper amdgpu_ttm_tt_affect_userptr to return userptr which is
inside the range. Add helper svm_range_check_vm_userptr to scan all
userptr of the vm, and return overlap userptr bo start, last.

Ido Schimmel says:

====================
mlxsw: Show per-band ECN-marked counter on qdisc

The RED qdisc can expose number of packets that it has marked through
the prob_marked counter (shown in iproute2 as "marked"). This counter
currently just shows number of packets marked in the SW datapath, which
in a switch deployment likely means zero.

Spectrum-3 does support per-TC counters, and in this patchset, mlxsw
supports this RED statistic properly.

15be36b812 mlxsw: spectrum_qdisc: Introduce per-TC ECN counters
The Qdisc code in mlxsw used to report a number of packets ECN-marked on a
port. Because reporting a per-port value as a per-TC value was misleading,
this was removed in commit 8a29581eb0 ("mlxsw: spectrum: Move the
ECN-marked packet counter to ethtool").

On Spectrum-3, a per-TC number of ECN-marked packets is available in per-TC
congestion counter group. Add a new array for the ECN counter, fetch the
values from the per-TC congestion group, and pick the value indicated by
tclass_num as appropriate.

On Spectrum-1 and Spectrum-2, this per-TC value is not available, and
zeroes will be reported, as they currently are.

1f922d9e37 Revert "net: procfs: add seq_puts() statement for dev_mcast"
This reverts commit ec18e84554.

It turns out that there are user space programs which got broken by that
change. One example is the "ifstat" program shipped by Debian:
https://packages.debian.org/source/bullseye/ifstat
which, confusingly enough, seems to not have anything in common with the
much more familiar (at least to me) ifstat program from iproute2:
https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/tree/misc/ifstat.c

root@debian:~# ifstat
ifstat: /proc/net/dev: unsupported format.

This change modified the header (first two lines of text) in
/proc/net/dev so that it looks like this:

The reason why the ifstat shipped by Debian (v1.1, with a Debian patch
upgrading it to 1.1-8.1 at the time of writing) is broken is because its
"proc" driver/backend parses the header very literally:

main/drivers.c#L825
  if (!data->checked && strncmp(buf, "Inter-|", 7))
    goto badproc;

and there's no way in which the header can be changed such that programs
parsing like that would not get broken.

Even if we fix this ancient and very "lightly" maintained program to
parse the text output of /proc/net/dev in a more sensible way, this
story seems bound to repeat again with other programs, and modifying
them all could cause more trouble than it's worth. On the other hand,
the reverted patch had no other reason than an aesthetic one, so
reverting it is the simplest way out.

I don't know what other distributions would be affected; the fact that
Debian doesn't ship the iproute2 version of the program (a different
code base altogether, which uses netlink and not /proc/net/dev) is
surprising in itself.

7d5fda1c84 tracing: Fix event probe removal from dynamic events
When an event probe is to be removed via the API that created it via the
dynamic events, an -ENOENT error is returned.

This is because the removal of the event probe does not expect to see the
event system and name that the event probe is attached to, even though
that's part of the API to create it. As the removal of probes is to use
the same API as they are created.

In fact, the removal is not consistent with the kprobes and uprobes
removal. Fix that by allowing various ways to remove the eprobe.

The eprobe is created with:

 e:[GROUP/]NAME SYSTEM/EVENT [OPTIONS]

Have it get removed by echoing in the following into dynamic_events:

 # Remove all eprobes with NAME
 echo '-:NAME' >> dynamic_events

 # Remove a specific eprobe
 echo '-:GROUP/NAME' >> dynamic_events
 echo '-:GROUP/NAME SYSTEM/EVENT' >> dynamic_events
 echo '-:NAME SYSTEM/EVENT' >> dynamic_events
 echo '-:GROUP/NAME SYSTEM/EVENT OPTIONS' >> dynamic_events
 echo '-:NAME SYSTEM/EVENT OPTIONS' >> dynamic_events

When resuming from low power, the driver attempts to restore the
configuration of some pins. This is done by a call to:
  stm32_pinctrl_restore_gpio_regs(struct stm32_pinctrl *pctl, u32 pin)
where 'pin' must be a valid pin value (i.e. matching some 'groups->pin').
Fix the current implementation which uses some wrong 'pin' value.

6dba4bdfd7 Revert "pinctrl: bcm: ns: support updated DT binding as syscon subnode"
This reverts commit a49d784d5a.

The updated binding was wrong / invalid and has been reverted. There
isn't any upstream kernel DTS using it and Broadcom isn't known to use
it neither. There is close to zero chance this will cause regression for
anyone.

Actually in-kernel bcm5301x.dtsi still uses the old good binding and so
it's broken since the driver update. This revert fixes it.

0398adaec3 Revert "dt-bindings: pinctrl: bcm4708-pinmux: rework binding to use syscon"
This reverts commit 2ae80900f2.

My rework was unneeded & wrong. It replaced a clear & correct "reg"
property usage with a custom "offset" one.

Back then I didn't understand how to properly handle CRU block binding.
I heard / read about syscon and tried to use it in a totally invalid
way. That change also missed Rob's review (obviously).

Northstar's pin controller is a simple consistent hardware block that
can be cleanly mapped using a 0x24 long reg space.

Since the rework commit there wasn't any follow up modifying in-kernel
DTS files to use the new binding. Broadcom also isn't known to use that
bugged binding. There is close to zero chance this revert may actually
cause problems / regressions.

This commit is a simple revert. Example binding may (should) be updated
/ cleaned up but that can be handled separately.

37f86649cd dt-bindings: leds: register-bit-led: Use 'reg' instead of 'offset'
'reg' is the standard property for defining register banks/addresses. Add
it to use for the register address and deprecate 'offset'. This also
allows for using standard node names with unit-addresses. However, since
it is quite possible to have multiple nodes at the same register
address, allow for the unit-address to optionally have the bit
offset. The unit-address format is '@<reg address>[,<bit offset>]'. This
matches the format recently added for nvmem binding which has the same
issue.

4ab43d1711 clk: qcom: Add lpass clock controller driver for SC7280
Add support for the lpass clock controller found on SC7280 based devices.
This would allow lpass peripheral loader drivers to control the clocks to
bring the subsystem out of reset.

d15eb80124 dt-bindings: clock: Add YAML schemas for LPASS clocks on SC7280
The LPASS(Low Power Audio Subsystem) clock provider have a bunch of generic
properties that are needed in a device tree. Add the LPASS clock IDs for
LPASS PIL client to request for the clocks.

As also shown on downstream dts[1], for a correct operation of the
Venus block, we have to retain MEM/PERIPH when halting the video_core,
video_axi and video_subcore0 branches: add these CXCs to the main
Venus GDSC.
