If all available channel resources are used for NAN channels, and one of
them is shared with another interface, and that interface needs to move
to a different channel (for example STA interface that needs to do a
channel or a link switch), then the driver can evacuate one of the NAN
channels (i.e. detach it from its channel resource and announce to the
peers that this channel is ULWed). In that case, the driver needs to
notify user space about the channel evacuation, so the user space can
adjust the local schedule accordingly.
Add a notification to let userspace know about it.

Currently we have this ability for AP and GO. But it is now needed also for
NAN_DATA mode - as per Wi-Fi Aware (TM) 4.0 specification 6.2.5:
"If a NAN Device receives a unicast NAN Data frame destined for it, but
with A1 address and A2 address that are not assigned to the NDP, it shall
discard the frame, and should send a Data Path Termination NAF to the
frame transmitter"
To allow this, change NL80211_CMD_UNEXPECTED_FRAME to support also
NAN_DATA, so drivers can report such cases and the user space can act
accordingly.

Add an NL80211 command to configure the NAN schedule of a NAN peer.
Such a schedule contains a list of NAN channels, and a mapping from each
time slots to the corresponding channel (or unscheduled).
Also contains more information about the schedule, such as sequence ID
and map ID.
Not all of the restrictions are validated in this patch. In particular,
comparison of two maps of the same peer requires storing/retrieving each
map of each peer, only for validation.
Therefore, it is the responsibilty of the driver to check that.

There are 2 types of logical links with a NAN peer:
- management (NMI), which is used for Tx/Rx of NAN management frames.
- data (NDI), which is used for Tx/Rx of data frames, or non-NAN
management frames.
The NMI station has two roles:
- representation of the NAN peer - for example, the peer's schedule
and the HT, VHT, HE capabilities - belong to the NMI station, and not to
the NDI ones.
- Tx/Rx of NAN management frames to/from the peer.
The NDI station is used for Tx/Rx data frames of a specific NDP that was
established with the NAN peer.
Note that a peer can choose to reuse its NMI address as the NDI address.
In that case, it is expected that two stations will be added even though
they will have the same address.
- An NDI station can only be added after the corresponding NMI station
was configured with capabilities.
- All the NDI stations will be removed before the NDI interface is brought
down.
- All NMI stations will be removed before NAN is stopped.
- Before NMI sta removal, all corresponding NDI stations will be removed
Add support for adding, removing, and changing NMI and NDI stations.

In NAN, unlike in other modes, there is only one set of (HT, VHT, HE)
capabilities that is used for all channels (and bands) used in the NAN
data path.
This set of capabilities will have to be a special one, for example - have
the minimum of (HT-for-5 GHz, HT-for-2.4 GHz), careful handling of the
bits that have a different meaning for each band, etc.
While we could use the exiting sband/iftype capabilities, and require
identical capabilities for all bands (makes no sense since this means
that we will have VHT capabilities in the 2.4 GHz slot),
or require that only one of the sbands will be set,
or have logic to extract the minimum and handle the conflicting bits -
it seems simpler to add a dedicated set of capabilities which is special
for NAN, and is band agnostic, to be populated by the driver.
That way we also let the driver decide how it wants to handle the
conflicting bits.
Add this special set of these capabilities to wiphy:nan_capabilities, to be
populated by the driver.
Send it to user space.

This new interface type represents a NAN data interface (NDI).
It is used for data communication with NAN peers.
Note that the existing NL80211_IFTYPE_NAN interface, which is the NAN
Management Interface (NMI), is used for management communication.
An NDI interface is started when a new NAN data path is about to
be established, and is stopped after the NAN data path is terminated.
- An NDI interface can only be started if the NMI is running, and NAN is
started.
- Before the NMI is stopped, the NDI interfaces will be stopped.
Add the new interface type, handle add/remove operations for it,
and makes sure of the conditions above.

Add an nl80211 API to allow user space to configure the local NAN
schedule.
The local schedule consists of a list of channel definitions and a schedule
map, in which each element covers a time slot and indicates on what
channel the device should be in that time slot.
Channels can be added to schedule even without being scheduled, for
reservation purposes.
A schedule can be configured either immedietally or be deferred, in case
there are already connected peers.
When the deferred flag is set, the command is a request from the device
to perform an announced schedule update: send the updated NAN
Availability - as set in this command - to the peers, and do the
actual switch to the new schedule on the right time (i.e. at the end of
the slot after the slot in which the update was sent to the peers).
In addition, a notification will be sent to indicate a deferred update
completion.

The test-case expects to have '/' in the xattr name.
However, HFS+ unicode logic makes conversion of '/'
into ':'. In HFS+, a filename can contain '/' because
':' is the separator. The slash is a valid filename
character on macOS. But on Linux, / is the path separator
and it cannot appear in a filename component. But xattr
name can contain any of these symbols. It means that
this unicode logic conversion doesn't need to be executed
for the case of xattr name.
This patch adds distinguishing the regular and xattr names.
If we have a regular name, then this conversion of special
symbols will be executed. Otherwise, the conversion is skipped
for the case of xattr names.

Add support for querying per-process buffer object (BO) memory
usage through the amdxdna GET_ARRAY UAPI.
Introduce a new query type, DRM_AMDXDNA_BO_USAGE, along with
struct amdxdna_drm_bo_usage to report BO memory usage statistics,
including heap, total, and internal usage.
Track BO memory usage on a per-client basis by maintaining counters
in GEM open/close and heap allocation/free paths. This ensures the
reported statistics reflect the current memory footprint of each
process.
Wire the new query into the GET_ARRAY implementation to expose
the usage information to userspace.

Tiny SRCU's srcu_gp_start_if_needed() directly calls schedule_work(),
which acquires the workqueue pool->lock.
This causes a lockdep splat when call_srcu() is called with a scheduler
lock held, due to:
call_srcu() [holding pi_lock]
srcu_gp_start_if_needed()
schedule_work() -> pool->lock
workqueue_init() / create_worker() [holding pool->lock]
wake_up_process() -> try_to_wake_up() -> pi_lock
Also add irq_work_sync() to cleanup_srcu_struct() to prevent a
use-after-free if a queued irq_work fires after cleanup begins.
Tested with rcutorture SRCU-T and no lockdep warnings.

Since commit c27cea4416a3 ("rcu: Re-implement RCU Tasks Trace in terms

happen basically everywhere (including where a scheduler lock is held),
call_srcu() now needs to avoid acquiring scheduler lock because
otherwise it could cause deadlock [1]. Fix this by following what the
previous RCU Tasks Trace did: using an irq_work to delay the queuing of

Tree SRCU has used non-raw spinlocks for many years, motivated by a desire
to avoid unnecessary real-time latency and the absence of any reason to
use raw spinlocks. However, the recent use of SRCU in tracing as the
underlying implementation of RCU Tasks Trace means that call_srcu()
is invoked from preemption-disabled regions of code, which in turn
requires that any locks acquired by call_srcu() or its callees must be
raw spinlocks.
This commit therefore converts SRCU's spinlocks to raw spinlocks.

These helpers have been deprecated for years and many drivers have

Use drm_atomic_helper_commit_tail_rpm() as commit tail to update the
plane after enabling the CRTC. Then remove the plane-update code from
mipi_dbi_enable_flush() and inline the remaining backlight code where
necessary.
Mipi-dbi's current commit tail drm_atomic_helper_commit_tail() first
updates the plane and then enables the CRTC. But the CRTC enablement
includes power management that prevents the initial plane update from
working. Hence, each mipi-dbi driver includes a plane update in their
CRTC enablement; in the form of mipi_dbi_enable_flush() or custom code.
Using drm_atomic_helper_commit_tail_rpm() enables the CRTC before any
plane updates. Hence the additional plane update can be removed from
mipi_dbi_enable_flush() and a number of drivers.
This leaves backlight_enable() in the helper, which can now be inlined
into affected drivers. Drivers now enable the CRTC plus an optional
backlight and then automatically update the plane.
In the case of disabling the display, drm_atomic_helper_commit_tail_rpm()
only disables the CRTC without touching the plane at all. Mipi-dbi's
mipi_dbi_pipe_disable() already contains the necessary logic.
Removing the plane update from the CRTC enablement will also help with
converting mipi-dbi from simple-pipe helpers to regular atomic helpers.

On AMD Ryzen Embedded V1780B (Family 17h, Zen 1), the BIOS does not
provide ACPI _CPC objects and the CPU does not support MSR-based CPPC
(X86_FEATURE_CPPC). The _PSS table only lists nominal P-states
(P0 = 3350 MHz), so when get_max_boost_ratio() fails at
cppc_get_perf_caps(), cpuinfo_max_freq reports only the base frequency
instead of the rated boost frequency (3600 MHz).
dmesg:
ACPI CPPC: No CPC descriptor for CPU:0
acpi_cpufreq: CPU0: Unable to get performance capabilities (-19)
cppc-cpufreq already has a DMI fallback (cppc_get_dmi_max_khz()) that
reads the processor max speed from SMBIOS Type 4. Export it and reuse
it in acpi-cpufreq as a last-resort source for the boost frequency.
A sanity check ensures the DMI value is above the _PSS P0 frequency
and within 2x of it; values outside that range are ignored and the
existing arch_set_max_freq_ratio() path is taken instead. The 2x
upper bound is based on a survey of the AMD Ryzen Embedded V1000
series, where the highest boost-to-base ratio is 1.8x (V1404I:
2.0 GHz base / 3.6 GHz boost).
The DMI lookup and sanity check are wrapped in a helper,
acpi_cpufreq_resolve_max_freq(), which falls through to
arch_set_max_freq_ratio() if the DMI value is absent or
out of range.
Tested on AMD Ryzen Embedded V1780B with v7.0-rc4:
Before: cpuinfo_max_freq = 3350000 (base only)
After: cpuinfo_max_freq = 3600000 (includes boost)

adm_ctx, call drbd_adm_prepare() at the top, call drbd_adm_finish()
at the bottom. This duplicated boilerplate across 25 handlers and
made error paths inconsistent, since some handlers could miss sending
the reply skb on early-exit paths.
The generic netlink framework already provides pre_doit/post_doit
hooks for exactly this purpose. An old comment even noted "this
would be a good candidate for a pre_doit hook".
Use them:
- pre_doit heap-allocates adm_ctx, looks up per-command flags from a
new drbd_genl_cmd_flags[] table, runs drbd_adm_prepare(), and
stores the context in info->user_ptr[0].
- post_doit sends the reply, drops kref references for
device/connection/resource, and frees the adm_ctx.
- Handlers just receive adm_ctx from info->user_ptr[0], set
reply_dh->ret_code, and return. All teardown is in post_doit.
- drbd_adm_finish() is removed, superseded by post_doit.

Power management blocks across the BCM2835 family share a common
base but require variant-specific handling. For instance, the
BCM2712 lacks ASB register space, yet it manages the power domain
for the V3D graphics block.
Add a hardware type identifier to the driver's private data. This
allows the driver to distinguish between SoC models and implement
custom quirks or features as needed.

CIDs set for MT6328, MT6331 and MT6332 are not appropriate.
Many Android downstream kernels define CID as below,
MT6328:
#define PMIC6328_E1_CID_CODE 0x2810
#define PMIC6328_E2_CID_CODE 0x2820
#define PMIC6328_E3_CID_CODE 0x2830
MT6331/MT6332:
#define PMIC6331_E1_CID_CODE 0x3110
#define PMIC6331_E2_CID_CODE 0x3120
#define PMIC6331_E3_CID_CODE 0x3130
#define PMIC6332_E1_CID_CODE 0x3210
#define PMIC6332_E2_CID_CODE 0x3220
#define PMIC6332_E3_CID_CODE 0x3230
The current configuration incorrectly uses the revision code as the CID.
Therefore, the driver cannot detect the same PMIC of different revisions.
(E1/E2 for MT6328, E1/E3 for MT6331/MT6332)
Based on these, the CID of MT6328, MT6331 and MT6332 should be corrected.
Additionally, the incorrect MT6331/MT6332 CID overlaps with the MT6320's
actual CID:
#define PMIC6320_E1_CID_CODE 0x1020
#define PMIC6320_E2_CID_CODE 0x2020
This causes a conflict in the switch-case statement of mt6397-irq.c,
this prevents adding support for MT6320.

One of the users of this driver - meraki-mx100 - abuses the software
node API by setting up a dummy software node without any logical link to
this GPIO controller and uses the fact that the GPIO core matches the
controller's label against the swnode's name to make the lookup work.
We want to remove this behavior from GPIOLIB in favor of actual matching
of firmware nodes but that would break this user. To facilitate that:
create a software node for the GPIO controller cell and expose its
address in the provided MFD header.

P010 stores 10-bit Y and interleaved UV samples in 16-bit little-endian

This requires 2 bytes per sample, so bytesperline is wWidth * 2.

Previously different architectures were using random sources of
differing strength and cost to decide the random kstack offset. A number
of architectures (loongarch, powerpc, s390, x86) were using their
timestamp counter, at whatever the frequency happened to be. Other
arches (arm64, riscv) were using entropy from the crng via
get_random_u16().
There have been concerns that in some cases the timestamp counters may
be too weak, because they can be easily guessed or influenced by user
space. And get_random_u16() has been shown to be too costly for the
level of protection kstack offset randomization provides.
So let's use a common, architecture-agnostic source of entropy; a
per-cpu prng, seeded at boot-time from the crng. This has a few
benefits:
- We can remove choose_random_kstack_offset(); That was only there to
try to make the timestamp counter value a bit harder to influence
from user space [*].
- The architecture code is simplified. All it has to do now is call
add_random_kstack_offset() in the syscall path.
- The strength of the randomness can be reasoned about independently
of the architecture.
- Arches previously using get_random_u16() now have much faster
syscall paths, see below results.
[*] Additionally, this gets rid of some redundant work on s390 and x86.
Before this patch, those architectures called
choose_random_kstack_offset() under arch_exit_to_user_mode_prepare(),
which is also called for exception returns to userspace which were *not*
syscalls (e.g. regular interrupts). Getting rid of
choose_random_kstack_offset() avoids a small amount of redundant work
for the non-syscall cases.
In some configurations, add_random_kstack_offset() will now call
instrumentable code, so for a couple of arches, I have moved the call a
bit later to the first point where instrumentation is allowed. This
doesn't impact the efficacy of the mechanism.
There have been some claims that a prng may be less strong than the
timestamp counter if not regularly reseeded. But the prng has a period
of about 2^113. So as long as the prng state remains secret, it should
not be possible to guess. If the prng state can be accessed, we have
bigger problems.
Additionally, we are only consuming 6 bits to randomize the stack, so
there are only 64 possible random offsets. I assert that it would be
trivial for an attacker to brute force by repeating their attack and
waiting for the random stack offset to be the desired one. The prng
approach seems entirely proportional to this level of protection.
Performance data are provided below. The baseline is v6.18 with rndstack
on for each respective arch. (I)/(R) indicate statistically significant
improvement/regression. arm64 platform is AWS Graviton3 (m7g.metal).
x86_64 platform is AWS Sapphire Rapids (m7i.24xlarge):

I tested an earlier version of this change on x86 bare metal and it
showed a smaller but still significant improvement. The bare metal
system wasn't available this time around so testing was done in a VM
instance. I'm guessing the cost of rdtsc is higher for VMs.

kstack_offset was previously maintained per-cpu, but this caused a
couple of issues. So let's instead make it per-task.
Issue 1: add_random_kstack_offset() and choose_random_kstack_offset()
expected and required to be called with interrupts and preemption
disabled so that it could manipulate per-cpu state. But arm64, loongarch
and risc-v are calling them with interrupts and preemption enabled. I
don't _think_ this causes any functional issues, but it's certainly
unexpected and could lead to manipulating the wrong cpu's state, which
could cause a minor performance degradation due to bouncing the cache
lines. By maintaining the state per-task those functions can safely be
called in preemptible context.
Issue 2: add_random_kstack_offset() is called before executing the
syscall and expands the stack using a previously chosen random offset.
choose_random_kstack_offset() is called after executing the syscall and
chooses and stores a new random offset for the next syscall. With
per-cpu storage for this offset, an attacker could force cpu migration
during the execution of the syscall and prevent the offset from being
updated for the original cpu such that it is predictable for the next
syscall on that cpu. By maintaining the state per-task, this problem
goes away because the per-task random offset is updated after the
syscall regardless of which cpu it is executing on.

When codel_dequeue() finds an empty queue, it resets vars->dropping
but does not reset vars->first_above_time. The reference CoDel
algorithm (Nichols & Jacobson, ACM Queue 2012) resets both:
dodeque_result codel_queue_t::dodeque(time_t now) {
...
if (r.p == NULL) {
first_above_time = 0; // <-- Linux omits this
}
...
}
Note that codel_should_drop() does reset first_above_time when called
with a NULL skb, but codel_dequeue() returns early before ever calling
codel_should_drop() in the empty-queue case. The post-drop code paths
do reach codel_should_drop(NULL) and correctly reset the timer, so a
dropped packet breaks the cycle -- but the next delivered packet
re-arms first_above_time and the cycle repeats.
For sparse flows such as ICMP ping (one packet every 200ms-1s), the
first packet arms first_above_time, the flow goes empty, and the
second packet arrives after the interval has elapsed and gets dropped.
The pattern repeats, producing sustained loss on flows that are not
actually congested.
Test: veth pair, fq_codel, BQL disabled, 30000 iptables rules in the
consumer namespace (NAPI-64 cycle ~14ms, well above fq_codel's 5ms
target), ping at 5 pps under UDP flood:
Before fix: 26% ping packet loss
After fix: 0% ping packet loss
Fix by resetting first_above_time to zero in the empty-queue path
of codel_dequeue(), matching the reference algorithm.
