The function ice_lag_is_switchdev_running() is being called from outside of
the LAG event handler code. This results in the lag->upper_netdev being
NULL sometimes. To avoid a NULL-pointer dereference, there needs to be a
check before it is dereferenced.

Proper testing greatly simplifies both patch development and review,
but it can be unclear what kind of userspace or guest support
should accompany new features. Clarify maintainer expectations
in terms of testing expectations; additionally, list the cases in
which open-source userspace support is pretty much a necessity and
its absence can only be mitigated by selftests.
While these ideas have long been followed implicitly by KVM contributors
and maintainers, formalize them in writing to provide consistent (though
not universal) guidelines.

Currently host sends HTT_TCL_METADATA_VER_V2 to the firmware
regardless of the operating mode (Mission or FTM).
Firmware expects additional software information (like peer ID, vdev
ID, and link ID) in Tx packets when HTT_TCL_METADATA_VER_V2 is set.
However, in FTM (Factory Test Mode) mode, no vdev is created on the
host side (this is expected). As a result, the firmware fails to find
the expected vdev during packet processing and ends up dropping
packets.
To fix this, send HTT_TCL_METADATA_VER_V1 in FTM mode because FTM
mode doesn't support HTT_TCL_METADATA_VER_V2.

The nbpf->chan[] array is allocated earlier in the nbpf_probe() function
and it has "num_channels" elements. These three loops iterate one
element farther than they should and corrupt memory.
The changes to the second loop are more involved. In this case, we're
copying data from the irqbuf[] array into the nbpf->chan[] array. If
the data in irqbuf[i] is the error IRQ then we skip it, so the iterators
are not in sync. I added a check to ensure that we don't go beyond the
end of the irqbuf[] array. I'm pretty sure this can't happen, but it
seemed harmless to add a check.
On the other hand, after the loop has ended there is a check to ensure
that the "chan" iterator is where we expect it to be. In the original
code we went one element beyond the end of the array so the iterator
wasn't in the correct place and it would always return -EINVAL. However,
now it will always be in the correct place. I deleted the check since
we know the result.

Reject KVM_SET_TSC_KHZ vCPU ioctl if guest's TSC is protected and not
changeable by KVM, and update the documentation to reflect it.
For such TSC protected guests, e.g. TDX guests, typically the TSC is
configured once at VM level before any vCPU are created and remains
unchanged during VM's lifetime. KVM provides the KVM_SET_TSC_KHZ VM
scope ioctl to allow the userspace VMM to configure the TSC of such VM.
After that the userspace VMM is not supposed to call the KVM_SET_TSC_KHZ
vCPU scope ioctl anymore when creating the vCPU.
The de facto userspace VMM Qemu does this for TDX guests. The upcoming
SEV-SNP guests with Secure TSC should follow.
Note, TDX support hasn't been fully released as of the "buggy" commit,
i.e. there is no established ABI to break.

TRAINING_PATTERN_SET
Commit a3ef3c2da675 ("drm/dp: Change AUX DPCD probe address from
DPCD_REV to LANE0_1_STATUS") stopped using the DPCD_REV register for
DPCD probing, since this results in link training failures at least when
using an Intel Barlow Ridge TBT hub at UHBR link rates (the
DP_INTRA_HOP_AUX_REPLY_INDICATION never getting cleared after the failed
link training). Since accessing DPCD_REV during link training is
prohibited by the DP Standard, LANE0_1_STATUS (0x202) was used instead,
as it falls within the Standard's valid register address range
(0x102-0x106, 0x202-0x207, 0x200c-0x200f, 0x2216) and it fixed the link
training on the above TBT hub.
However, reading the LANE0_1_STATUS register also has a side-effect at
least on a Novatek eDP panel, as reported on the Closes: link below,
resulting in screen flickering on that panel. One clear side-effect when
doing the 1-byte probe reads from LANE0_1_STATUS during link training
before reading out the full 6 byte link status starting at the same
address is that the panel will report the link training as completed
with voltage swing 0. This is different from the normal, flicker-free
scenario when no DPCD probing is done, the panel reporting the link
training complete with voltage swing 2.
Using the TRAINING_PATTERN_SET register for DPCD probing doesn't have
the above side-effect, the panel will link train with voltage swing 2 as
expected and it will stay flicker-free. This register is also in the
above valid register range and is unlikely to have a side-effect as that
of LANE0_1_STATUS: Reading LANE0_1_STATUS is part of the link training
CR/EQ sequences and so it may cause a state change in the sink - even if
inadvertently as I suspect in the case of the above Novatek panel. As
opposed to this, reading TRAINING_PATTERN_SET is not part of the link
training sequence (it must be only written once at the beginning of the
CR/EQ sequences), so it's unlikely to cause any state change in the
sink.
As a side-note, this Novatek panel also lacks support for TPS3, while
claiming support for HBR2, which violates the DP Standard (the Standard
mandating TPS3 for HBR2).
Besides the Novatek panel (PSR 1), which this change fixes, I also
verified the change on a Samsung (PSR 1) and an Analogix (PSR 2) eDP
panel as well as on the Intel Barlow Ridge TBT hub.
Note that in the drm-tip tree (targeting the v6.17 kernel version) the
i915 and xe drivers keep DPCD probing enabled only for the panel known
to require this (HP ZR24w), hence those drivers in drm-tip are not
affected by the above problem.

After commit aa7a9275ab81 ("PM: sleep: Suspend async parents after
suspending children"), the following scenario is possible:
1. Device A is async and it depends on device B that is sync.
2. Async suspend is scheduled for A before the processing of B is
started.
3. A is waiting for B.
4. In the meantime, an unrelated device fails to suspend and returns
an error.
5. The processing of B doesn't start at all and its power.completion is
not updated.
6. A is still waiting for B when async_synchronize_full() is called.
7. Deadlock ensues.
To prevent this from happening, update power.completion for all devices
on errors in all suspend phases, but do not do it directly for devices
that are already being processed or are waiting for the processing to
start because in those cases it may be necessary to wait for the
processing to actually complete before updating power.completion for
the device.

The recently introduced support for freezing filesystems during system
suspend included calls to filesystems_freeze() in both suspend_prepare()
and enter_state(), as well as calls to filesystems_thaw() in both
suspend_finish() and the Unlock path in enter_state(). These are
redundant.
Moreover, calling filesystems_freeze() twice, from both suspend_prepare()
and enter_state(), leads to a black screen and makes the system unable
to resume in some cases.
Address this as follows:
- filesystems_freeze() is already called in suspend_prepare(), which
is the proper and consistent place to handle pre-suspend operations.
The second call in enter_state() is unnecessary and so remove it.
- filesystems_thaw() is invoked in suspend_finish(), which covers
successful suspend/resume paths. In the failure case, add a call
to filesystems_thaw() only when needed, avoiding the duplicate call
in the general Unlock path.
This change simplifies the suspend code and avoids repeated freeze/thaw
calls, while preserving correct ordering and behavior.

The pm_restore_gfp_mask() call added by commit 12ffc3b1513e ("PM:
Restrict swap use to later in the suspend sequence") to
suspend_devices_and_enter() is done too early because it takes
place before calling dpm_resume() in dpm_resume_end() and some
swap-backing devices may not be ready at that point. Moreover,
dpm_resume_end() called subsequently in the same code path invokes
pm_restore_gfp_mask() again and calling it twice in a row is
pointless.
Drop the misplaced pm_restore_gfp_mask() call from
suspend_devices_and_enter() to address this issue.

Kernel panic - not syncing: BRK handler: Fatal exception
Dan has also reported following issues with the original patch
https://lore.kernel.org/all/33fe8fe7-719a-405a-9ed2-d9f816ce1d57@sabinyo.mountain/
Bug #1:
The zeroeth element of ctrl->pconfig[] is supposed to be unused. We
start counting at 1. However this code sets ctrl->pconfig[0].ch_mask = 128.
Bug #2:
There are SLIM_MAX_TX_PORTS (16) elements in tx_ch[] array but only
QCOM_SDW_MAX_PORTS + 1 (15) in the ctrl->pconfig[] array so it corrupts
memory like Yongqin Liu pointed out.
Bug 3:
Like Jie Gan pointed out, it erases all the tx information with the rx
information.

net: mctp: Improved bind handling
This series improves a couple of aspects of MCTP bind() handling.
MCTP wasn't checking whether the same MCTP type was bound by multiple
sockets. That would result in messages being received by an arbitrary
socket, which isn't useful behaviour. Instead it makes more sense to
have the duplicate binds fail, the same as other network protocols.
An exception is made for more-specific binds to particular MCTP
addresses.
It is also useful to be able to limit a bind to only receive incoming
request messages (MCTP TO bit set) from a specific peer+type, so that
individual processes can communicate with separate MCTP peers. One
example is a PLDM firmware update requester, which will initiate
communication with a device, and then the device will connect back to the
requester process.
These limited binds are implemented by a connect() call on the socket
prior to bind. connect() isn't used in the general case for MCTP, since
a plain send() wouldn't provide the required MCTP tag argument for
addressing.

Prior to calling bind() a program may call connect() on a socket to
restrict to a remote peer address.
Using connect() is the normal mechanism to specify a remote network
peer, so we use that here. In MCTP connect() is only used for bound
sockets - send() is not available for MCTP since a tag must be provided
for each message.
The smctp_type must match between connect() and bind() calls.

When a specific EID is passed as a bind address, it only makes sense to
interpret with an actual network ID, so resolve that to the default
network at bind time.
For bind address of MCTP_ADDR_ANY, we want to be able to capture traffic
to any network and address, so keep the current behaviour of matching
traffic from any network interface (don't interpret MCTP_NET_ANY as
the default network ID).

Disallow bind() calls that have the same arguments as existing bound
sockets. Previously multiple sockets could bind() to the same

for MCTP_ADDR_ANY versus specific EID bind(), which are allowed to exist

Fixes reset GPIO usage during probe by ensuring we retrieve the GPIO and
take the device out of reset (if it defaults to being in reset) before
we attempt to communicate with the device. This is achieved by moving
the call to tcan4x5x_get_gpios() before tcan4x5x_find_version() and
avoiding any device communication while getting the GPIOs. Once we
determine the version, we can then take the knowledge of which GPIOs we
obtained and use it to decide whether we need to disable the wake or
state pin functions within the device.
This change is necessary in a situation where the reset GPIO is pulled
high externally before the CPU takes control of it, meaning we need to
explicitly bring the device out of reset before we can start
communicating with it at all.
This also has the effect of fixing an issue where a reset of the device
would occur after having called tcan4x5x_disable_wake(), making the
original behavior not actually disable the wake. This patch should now
disable wake or state pin functions well after the reset occurs.

In cfg80211_off_channel_oper_allowed(), the current logic disallows
off-channel operations if any link operates on a radar channel,
assuming such channels cannot be vacated. This assumption holds for
non-MLO interfaces but not for MLO.
With MLO and multi-radio devices, different links may operate on
separate radios. This allows one link to scan off-channel while
another remains on a radar channel. For example, in a 5 GHz
split-phy setup, the lower band can scan while the upper band
stays on a radar channel.
Off-channel operations can be allowed if the radio/link onto which the
input channel falls is different from the radio/link which has an active
radar channel. Therefore, fix cfg80211_off_channel_oper_allowed() by
returning false only if the requested channel maps to the same radio as
an active radar channel. Allow off-channel operations when the requested
channel is on a different radio, as in MLO with multi-radio setups.

The ieee80211_csa_finish() function currently uses for_each_sdata_link()
to iterate over links of sdata. However, this macro internally uses
wiphy_dereference(), which expects the wiphy->mtx lock to be held.
When ieee80211_csa_finish() is invoked under an RCU read-side critical
section (e.g., under rcu_read_lock()), this leads to a warning from the
RCU debugging framework.
WARNING: suspicious RCU usage
net/mac80211/cfg.c:3830 suspicious rcu_dereference_protected() usage!
This warning is triggered because wiphy_dereference() is not safe to use
without holding the wiphy mutex, and it is being used in an RCU context
without the required locking.
Fix this by introducing and using a new macro, for_each_sdata_link_rcu(),
which performs RCU-safe iteration over sdata links using
list_for_each_entry_rcu() and rcu_dereference(). This ensures that the
link pointers are accessed safely under RCU and eliminates the warning.

Since there's no TPE element in the (re)assoc response, trying
to use the data from it just leads to using the defaults, even
though the real values had been set during authentication from

Fix this by simply not handling the TPE data in assoc response
since it's not intended to be present, if it changes later the
necessary changes will be made by tracking beacons later.

in (**), the maximum between the capability width and the bss width is
returned. But the bss width was just updated to 40 in (*),
so the action frame handling code will increase the width of the rate
control before the chanctx was increased (in ***), leading to a FW error
(at least in iwlwifi driver. But this is wrong regardless).
Fix this by simply handling the action frame async, so it won't race
with the beacon proccessing.
