Pull scheduler fixes from Ingo Molnar:
- Fix spurious failures in rseq self-tests (Mark Brown)
- Fix rseq rseq::cpu_id_start ABI regression due to TCMalloc's creative
use of the supposedly read-only field
The fix is to introduce a new ABI variant based on a new (larger)
rseq area registration size, to keep the TCMalloc use of rseq
backwards compatible on new kernels (Thomas Gleixner)
- Fix wakeup_preempt_fair() for not waking up task (Vincent Guittot)
- Fix s64 mult overflow in vruntime_eligible() (Zhan Xusheng)

Replace the genl_magic multi-include macro system with explicit
serialization and parsing.
The *_gen files were initially produced from a YNL spec via a
customized ynl-gen-c, but the DRBD netlink family is effectively
frozen, so the generator is kept unmodified.
All new functionality will land in a separate, properly-designed
family.
Carry the resulting code as ordinary in-tree source rather than
landing the spec and generator changes that produced it.
The bulk of the changes are mechanical renames to fit the YNL naming
conventions:
- Handler functions: drbd_adm_* -> drbd_nl_*_doit/dumpit
- GENL_MAGIC_VERSION -> DRBD_FAMILY_VERSION
- GENL_MAGIC_FAMILY_HDRSZ -> sizeof(struct drbd_genlmsghdr)
- drbd_genl_family -> drbd_nl_family
- Attribute IDs: T_* -> DRBD_A_*
Remove the nested_attr_tb static global buffer and move to a per-call
allocation approach: each deserialization manages its own nested
attribute table. This will be needed anyway when we eventually move
to parallel_ops, and it's actually simpler this way, so make the
move now.
Replace the functionality of the "sensitive" flag: this was only used
by a single field (shared_secret); open-code redaction logic for that
locally.
Also replace the "invariant" flag: this only had a couple of users,
and those basically never change. Hard code the check directly inline.
The genl_family struct itself is defined manually in drbd_nl.c.
Also replace a couple of drbd-specific wrappers (nla_put_u64_0pad,
drbd_nla_find_nested) with standard kernel functions while we're at
it.
Finally, completely remove the genl_magic system; DRBD was its only
user.

drbd.h and drbd_limits.h contain only type definitions, enums, and
constants shared between kernel and userspace. These should be part of
UAPI.
Split the genl_api header into two: the genlmsghdr and the enums are
UAPI, the rest stays there for now (it will be removed by one of the
next commits in this series).
drbd_config.h is clearly DRBD-internal, so move it there.

Add the necessary fields to the chandef data structure
to represent NPCA (the NPCA primary channel and NPCA
punctured/disabled subchannels bitmap), and the code
to check these for validity, compatibility, as well as
allowing it to be passed for AP mode for capable
devices.
Compatibility is assumed to only be the case when it's
actually identical, enabling later management of this
in channel contexts in mac80211 for multiple APs, but
requiring userspace to set up the identical chandef on
all AP interfaces that share a channel (and BSS color.)

For UHR, multi-link power-management capability lives there, and
so it's needed that hostapd knows what to advertise, and clients
should have it shown to userspace for information.
Repurpose the existing NL80211_ATTR_ASSOC_MLD_EXT_CAPA_OPS by
renaming it to NL80211_ATTR_EXT_MLD_CAPA_AND_OPS (with a define
for compatibility) and advertise the capabilities.
We can also later use the value, if needed, to set per-station
capabilities on STAs added to AP interfaces.

Currently there is no way to install an LTF key seed that can be
used in non-trigger-based (NTB) and trigger-based (TB) FTM ranging
to protect NDP frames. Without this, drivers cannot enable PHY-layer
security for peer measurement sessions, leaving ranging measurements
vulnerable to eavesdropping and manipulation.
Introduce NL80211_KEY_LTF_SEED attribute and the dedicated extended
feature flag NL80211_EXT_FEATURE_SET_KEY_LTF_SEED to allow drivers
to advertise and install LTF key seeds via nl80211. The key seed
must be configured beforehand to ensure the peer measurement session
is secure. The driver must advertise both NL80211_EXT_FEATURE_SECURE_LTF
and NL80211_EXT_FEATURE_SET_KEY_LTF_SEED for the key seed installation
to be permitted.
The LTF key seed is pairwise key material and must only be used with
pairwise key type. Reject attempts to use it with other key types.

Proximity detection often does not require detailed ranging
measurements, yet userspace currently receives full FTM results for
every request, causing unnecessary data transfer, host wakeups, and
processing overhead.
Add an optional control to suppress ranging result reporting for
peer-to-peer PD requests. Introduce the
NL80211_PMSR_FTM_REQ_ATTR_PD_SUPPRESS_RESULTS flag; when set with a
PD request, the device may perform the measurements (e.g. when acting
as RSTA) but must not report the measurement results to userspace.
Validate that the flag is only accepted when request_type is set to
NL80211_PMSR_FTM_REQ_TYPE_PD, reject otherwise.

When a role limit is advertised, validate the number of peers in the

Introduce Proximity Detection (PD) capabilities in Peer Measurement
Service (PMSR) as defined in the Wi-Fi Alliance specification
"Proximity Ranging (PR) Implementation Consideration Draft 1.9 Rev 1
section 3.3". This enables devices to advertise peer to peer ranging
support.
Restructure FTM capabilities in cfg80211_pmsr_capabilities to replace
the single support_rsta flag with nested ista and rsta sub-structs,
each carrying per-mode flags for Non-Trigger Based (NTB), Trigger Based
(TB), and EDCA based ranging. This allows drivers to advertise detailed
role and protocol support for both initiator and responder roles.
Add support to pass additional ISTA and RSTA role capabilities to
userspace using new nested ISTA_CAPS and RSTA_CAPS attributes. The
legacy RSTA_SUPPORT flag is retained for backward compatibility.
Add NL80211_PMSR_FTM_CAPA_ATTR_TYPE_CAPS nested attribute using the
nl80211_peer_measurement_ftm_type_capa enum with two sub-flags:
NL80211_PMSR_FTM_TYPE_CAPA_ATTR_INFRA_SUPPORT for STA-to-AP or
AP-to-STA ranging, and NL80211_PMSR_FTM_TYPE_CAPA_ATTR_PD_SUPPORT
for peer-to-peer ranging.
Add CONCURRENT_ISTA_RSTA_SUPPORT as a FTM capability flag indicating
the device can simultaneously act as initiator and responder in a
multi-peer measurement request.
Extend FTM capabilities with antenna configuration fields
(max_no_of_tx_antennas, max_no_of_rx_antennas) for the PR Element
during PASN negotiation, and ranging interval limits
(min_allowed_ranging_interval_edca, min_allowed_ranging_interval_ntb)
to advertise device timing constraints for EDCA and NTB-based ranging.
Update the FTM request validation path in pmsr.c to check RSTA
requests against the per-mode rsta capabilities (NTB, TB, EDCA),
rejecting requests for modes the device does not support.

Add a new wdev-only interface type NL80211_IFTYPE_PD to support
Proximity Detection (PD) operations such as PASN and peer measurement
operations. This interface type operates without a netdev, similar to
P2P_DEVICE and NAN interfaces.
Implement support across cfg80211 and mac80211 layers with PD-specific
checks gated by the NL80211_EXT_FEATURE_SECURE_RTT feature flag,
management frame registration and transmission capabilities, and proper
channel context handling where PD interfaces are excluded from bandwidth
calculations. Update mac80211 to recognize the new interface type in the
relevant paths for this management-only interface.
PD discovery can be performed on any available interface, such as
NL80211_IFTYPE_STATION.
If PD/PMSR uses the MAC address of an existing interface type, such as
NL80211_IFTYPE_STATION, then pairing and measurement shall use that
same interface. If PD/PMSR uses a different MAC address, such as a
random MAC address, then pairing and measurement can be performed on a
new NL80211_IFTYPE_PD interface created with that random MAC address.

Currently the remain_on_channel operation does not support
filtering incoming frames by destination MAC address. This
prevents use cases such as PASN authentication in the
responder side that need to receive frames addressed to a
specific MAC during the off-channel period.
Add an rx_addr parameter to the remain_on_channel operation
callback and propagate it through the call chain from nl80211
to driver implementations. Introduce the extended feature
NL80211_EXT_FEATURE_ROC_ADDR_FILTER as a capability gate so
that cfg80211 rejects the request if the driver does not
advertise support for address filtering. Extract the address
from the NL80211_ATTR_MAC attribute when provided in the
netlink message and update the tracing infrastructure to
include the address in remain_on_channel trace events. The
rx_addr parameter is optional and can be NULL, maintaining
backward compatibility with existing drivers.

Add greyscale Y8 format.
The 8-bit greyscale format has been discussed before, and the earlier
guidance was to use DRM_FORMAT_R8, as a single-channel 8-bit pixel.
However, adding DRM_FORMAT_Y8 makes sense, we can mark it as 'is_yuv' in
the drm_format_info, and this can help the drivers handle e.g.
full/limited range. This will distinguish two single-channel formats:
R8, which is a RGB format with the same value for all components, and
Y8, which is a Y-only YCbCr format, with Cb and Cr being neutral.

In SME-in-driver mode, the driver handles the entire (re)association
exchange. Userspace (e.g., wpa_supplicant) currently has no explicit
indication of whether the (re)association exchange was encrypted,
making it difficult to distinguish EPP (Enhanced Privacy Protection,
IEEE 802.11bi) associations from non-EPP associations.
When (Re)Association frame encryption is used, the (Re)Association
Response frame must contain a Key Delivery element as specified in
IEEE P802.11bi/D4.0, Table 9-65. Userspace must process this element
only when the (Re)Association Response frame is actually encrypted.
Processing it unconditionally for unencrypted frames leads to incorrect
behavior. Without an explicit indication from the driver, userspace
cannot determine whether encryption was used and whether the Key
Delivery element is valid.
Add a new flag attribute NL80211_ATTR_ASSOC_ENCRYPTED and a
corresponding field "assoc_encrypted" in cfg80211_connect_resp_params
to indicate that both the (Re)Association Request and Response frames
are transmitted encrypted over the air.
For mac80211-based drivers, extend cfg80211_rx_assoc_resp_data with
the assoc_encrypted field as well, which is then propagated to
cfg80211_connect_resp_params.
Pass the flag to userspace via NL80211_CMD_CONNECT event.

https://gitlab.freedesktop.org/drm/xe/kernel into drm-next
UAPI Changes:
- Debugfs multi-LRC engine info (Xin Wang, 2 commits)
Expose multi-LRC engine classes in the debugfs engine info output
and improve the output readability.
- drm/drm_ras: Add clear-error-counter netlink command to drm_ras
Cross-subsystem Changes:
Core Changes:
- drm/gpusvm: Reject VMAs with VM_IO or VM_PFNMAP when creating SVM ranges
- drm/i915/display: switch to including common step file directly
Driver Changes:
- Engine initialization cleanup (Matt Roper, 10 commits)
Clean up engine initialization code inherited from i915 by moving
hardware programming (CCS enablement, HWSTAM, GFX_MODE, BLIT_CCTL,
STOP_RING) into the RTP infrastructure. This makes the programming
visible and verifiable via debugfs, and applies consistently across
both normal and execlist init paths. Also fixes the name/definition
of GFX_MODE, marks BCS engines as belonging to the GT forcewake
domain, and drops the now-unused xe_hw_engine_mmio_write32() helper.
- PF fair scheduling auto-provisioning (Michal Wajdeczko, 13 commits)
Fix several corner cases in SR-IOV PF scheduling policy provisioning,
then auto-provision PF and all VFs with 16ms execution-quantum and
preemption-timeout defaults. This prevents a VF from monopolizing
the GPU by submitting workloads without gaps, without requiring the
user to configure sysfs manually.
- System Controller support for CRI/Xe3p (Anoop Vijay + Raag Jadav, 10 commits)
Add xe_sysctrl infrastructure for communicating with the System
Controller firmware entity on CRI/Xe3p discrete GPU platforms via a
mailbox interface. Includes type definitions, register definitions,
mailbox communication, initialization, power management, interrupt
handling, and event dispatch. Builds on this to add initial RAS
correctable error handling, using sysctrl interrupts to receive
threshold-crossed events.
- PXP state machine fixes (Daniele Ceraolo Spurio, 4 commits)
Fix PXP state machine handling: reject PXP sessions on PTL platforms
with older GSC firmware that does not support it, fix the restart
flag not being cleared after jumping back in pxp_start, remove
incorrect handling of an impossible state during suspend, and clean
up termination status on failure.
- Reset/wedge/unload corner case fixes (Zhanjun Dong + Matthew Brost, 5 commits)
Fix memory leaks and fence signal failures that occurred during GPU
reset, device wedging, and driver unload by forcefully tearing down
remaining exec queues in GuC submit fini, always killing queues in
pause/abort, and triggering queue cleanup when not in wedged mode 2.
Also ensures GuC CT state transitions via STOP before DISABLED.
- Wedge path memory allocation fixes (Matthew Brost, 3 commits)
Avoid GFP_KERNEL allocations in xe_device_declare_wedged(), which
runs in the DMA-fence signaling path. Also drops the
guc_submit_wedged_fini devm registration from xe_guc_submit_wedge()
to clean up the wedge shutdown sequence.
- PAT type cleanup and invalid index hardening (Xin Wang, 3 commits)
Standardize pat_index fields to u16 across the driver, default
XE_CACHE_NONE_COMPRESSION to XE_PAT_INVALID_IDX (matching
WB_COMPRESSION), and introduce xe_cache_pat_idx() — a macro helper
that validates cache_mode bounds and asserts on invalid PAT indices
before returning the index.
- Reject unsafe PAT indices for CPU cached memory (Jia Yao, 2 commits)
Reject incoherent (coh_none) PAT indices for CPU cached memory in
both the madvise ioctl and vm_bind with CPU_ADDR_MIRROR flag, closing
a security gap where the GPU could bypass CPU caches and observe
stale or sensitive data.
- OA improvements for CRI device memory (Ashutosh Dixit, 3 commits)
Move OA buffer access to the xe_map layer to support both system and
device memory (required for CRI), switch OA buffer mmap to use
drm_gem_mmap_obj, and implement workaround Wa_14026633728.
- xe_drm.h documentation fixes (Shuicheng Lin, 6 commits)
Fix multiple documentation issues in the xe_drm.h UAPI header:
typos, spelling errors, grammar, wrong names and references,
kernel-doc cross-reference syntax, and broken code examples.
- kernel-doc syntax fixes in xe headers (Shuicheng Lin, 4 commits)
Fix kernel-doc syntax issues across xe header files: missing '@'
prefixes on member tags, stale/mismatched member tags, comment
syntax errors, and type/parameter name mismatches in references.
- Buffer object and DMA-buf resource leak fixes (Shuicheng Lin, 4 commits)
Fix resource leaks on error paths: DMA-buf attachment leak in
xe_gem_prime_import(), BO leak in xe_dma_buf_init_obj() on
allocation failure, and BO leaks in xe_bo_init_locked() on GGTT
flag validation and unaligned size validation failures.
- Include guard cleanup (Shuicheng Lin, 5 commits)
Fix and standardize include guards across xe header files: normalize
double-underscore guards to single, add missing leading/trailing
underscores, add missing _H suffixes, and add guards to previously
unprotected headers.
- VF CCS memory pool (Satyanarayana K V P, 2 commits)
Switch VF CCS read/write operations from the DRM sub-allocator to
DRM mm, fixing allocation failures in fence-disabled mode where
the sub-allocator's hole cursor assumption breaks. Also introduces
a general BO-backed memory pool with shadow support using drm_mm.
- i915/xe step definition unification (Jani Nikula, 3 commits)
Complete the migration to the shared intel_step header: switch xe
from its own xe_step enum to the shared intel_step naming and
definitions, and update i915 display code to include the common
step header directly.
- Xe3p GT tuning fixes (3 commits)
Three Xe3p GT tuning corrections: fix the register offset for
GAMSTLB_CTRL, stop applying the CCCHKNREG1 tuning from Xe3p onward
(no longer needed), and mark ROW_CHICKEN5 as a masked register.
- Forcewake cleanup in GT and GuC PC (Raag Jadav, 3 commits)
Drop a redundant forcewake reference in xe_gt, reorder forcewake
usage in xe_guc_pc_fini_hw() to avoid a redundant hold, and convert
xe_guc_pc_stop() to void since it can no longer fail.
- SVM garbage collector fix on close (Matthew Brost, 2 commits)
Disable the SVM garbage collector work item when an SVM is closed
to prevent use-after-free when the GC fires after the SVM is freed.
- Admin-only PF mode (Satyanarayana K V P, 2 commits)
Derive an "admin-only PF" mode flag from xe_device state instead of
using a local flag, and restrict device query responses when running
in admin-only PF mode to avoid exposing internal state.
- Enable hwmon energy attributes and accepted power limit for CRI (2 commits)
Enable energy consumption hwmon attributes for the CRI platform and
add support for reading the accepted (sustained) power limit via
hwmon.

Add pin-operstate enum and operstate_on_dpll_get callback to report
the actual hardware status of a pin with respect to its parent DPLL
device. Unlike pin-state (which reflects administrative intent set
by the user), operstate reflects what the hardware is actually doing.
Defined operational states:
- active: pin is qualified and actively used by the DPLL
- standby: pin is qualified but not actively used by the DPLL
- no-signal: pin does not have a valid signal
- qual-failed: pin signal failed qualification
The operstate is reported inside the pin-parent-device nested
attribute alongside the existing state and phase-offset attributes.

Incrementally consumed buffer rings are generally fully consumed, but
it's quite possible that the application has a minimum size it needs to
meet to avoid truncation. Currently that minimum limit is 1 byte, but
this should be a setting that is the hands of the application. For
recvmsg multishot, a prime use case for incrementally consumed buffers,
the application may get spurious -EFAULT returned at the end of an
incrementally consumed buffer, as less space is available than the
headers need.
Grab a u32 field in struct io_uring_buf_reg, which the application can
use to inform the kernel of the minimum size that should be available
in an incrementally consumed buffer. If less than that is available,
the current buffer is fully processed and the next one will be picked.

"Delete some obsolete networking code
Old code like amateur radio and NFC have long been a burden to core

noobs try to fix them.
If we want to have a fighting chance of surviving the LLM-pocalypse
this code needs to find a dedicated owner or get deleted. We've talked
about these deletions multiple times in the past and every time
someone wanted the code to stay. It is never very clear to me how many
of those people actually use the code vs are just nostalgic to see it
go. Amateur radio did have occasional users (or so I think) but most
users switched to user space implementations since its all super slow
stuff. Nobody stepped up to maintain the kernel code.
We were lucky enough to find someone who wants to help with NFC so
we're giving that a chance. Let's try to put the rest of this code

Remove the amateur radio (AX.25, NET/ROM, ROSE) protocol implementation
and all associated hamradio device drivers from the kernel tree.
This set of protocols has long been a huge bug/syzbot magnet,
and since nobody stepped up to help us deal with the influx
of the AI-generated bug reports we need to move it out of tree
to protect our sanity.
The code is moved to an out-of-tree repo:
https://github.com/linux-netdev/mod-orphan
if it's cleaned up and reworked there we can accept it back.
Minimal stub headers are kept for include/net/ax25.h (AX25_P_IP,
AX25_ADDR_LEN, ax25_address) and include/net/rose.h (ROSE_ADDR_LEN)
so that the conditional integration code in arp.c and tun.c continues

Remove the ISDN (mISDN, CAPI) subsystem and Bluetooth CMTP protocol
from the kernel tree.
ISDN is a pretty old technology and it's unclear whether anyone still
uses it. I went over the last few years of git history and all the
commits are either tree-wide conversions or syzbot/static analyzer
fixes.
When we discussed removal in the past IIRC there were some concerns
about ISDN still being used in parts of Germany. Unfortunately, the
code base is quite old, none of the current maintainers are familiar
with it and AI tools will have a field day finding bugs here.
Delete this code and preserve it in an out-of-tree repository
for any remaining users:
https://github.com/linux-netdev/mod-orphan
UAPI constants AF_ISDN/PF_ISDN and the SELinux isdn_socket class
are preserved for ABI stability, but the rest of uAPI is removed.

Remove CAIF (Communication CPU to Application CPU Interface), the
ST-Ericsson modem protocol. The subsystem has been orphaned since 2013.
The last meaningful changes from the maintainers were in March 2013:
a8c7687bf216 ("caif_virtio: Check that vringh_config is not null")
b2273be8d2df ("caif_virtio: Use vringh_notify_enable correctly")
0d2e1a2926b1 ("caif_virtio: Introduce caif over virtio")
Not-so-coincidentally, according to "the Internet" ST-Ericsson officially
shut down its modem joint venture in Aug 2013.
If anyone is using this code please yell!
In the 13 years since, the code has accumulated 200 non-merge commits,
of which 71 were cross-tree API changes, 21 carried Fixes: tags, and
the remaining ~110 were cleanups, doc conversions, treewide refactors,
and one partial removal (caif_hsi, ca75bcf0a83b).
We are still getting fixes to this code, in the last 10 days there were
3 reports on security@ about CAIF that I have been CCed on.
UAPI constants (AF_CAIF, ARPHRD_CAIF, N_CAIF, VIRTIO_ID_CAIF) and the
SELinux classmap entry are intentionally kept for ABI stability.

BTF maximum vlen is encoded using 16 bits with a maximum vlen
of 65535. This has sufficed for structs, function parameters
and enumerated type values. However, with upcoming BTF location
information - in particular information about inline sites -
this limit is surpassed. Use bits 16-23 - currently unused in
BTF info - to extend to 24 bits, giving a max vlen of (2^24 - 1),
or 16 million.
Also extend BTF kind encoding from 5 to 7 bits, giving a maximum
available number of kinds of 128. Since with the BTF location work
we use another 3 kinds, we are fast approaching the current limit
of 32.
Convert BTF_MAX_* values to enums to allow them to be encoded in
kernel BTF; this will allow us to detect if the running kernel
supports a 24-bit vlen or not. Add one for max _possible_
(not used) kind.
Fix up a few places in the kernel where a 16-bit vlen is assumed;
remove BTF_INFO_MASK as now all bits are used.
The vlen expansion was suggested by Andrii in [1]; the kind expansion
is tackled here too as it may be needed also to support new kinds
in BTF.
