8be4d31cb8 Networking changes for 6.17. 
Core & protocols
 ----------------
 
  - Wrap datapath globals into net_aligned_data, to avoid false sharing.
 
  - Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container).
 
  - Add SO_INQ and SCM_INQ support to AF_UNIX.
 
  - Add SIOCINQ support to AF_VSOCK.
 
  - Add TCP_MAXSEG sockopt to MPTCP.
 
  - Add IPv6 force_forwarding sysctl to enable forwarding per interface.
 
  - Make TCP validation of whether packet fully fits in the receive
    window and the rcv_buf more strict. With increased use of HW
    aggregation a single "packet" can be multiple 100s of kB.
 
  - Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
    improves latency up to 33% for sockmap users.
 
  - Convert TCP send queue handling from tasklet to BH workque.
 
  - Improve BPF iteration over TCP sockets to see each socket exactly once.
 
  - Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code.
 
  - Support enabling kernel threads for NAPI processing on per-NAPI
    instance basis rather than a whole device. Fully stop the kernel NAPI
    thread when threaded NAPI gets disabled. Previously thread would stick
    around until ifdown due to tricky synchronization.
 
  - Allow multicast routing to take effect on locally-generated packets.
 
  - Add output interface argument for End.X in segment routing.
 
  - MCTP: add support for gateway routing, improve bind() handling.
 
  - Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink.
 
  - Add a new neighbor flag ("extern_valid"), which cedes refresh
    responsibilities to userspace. This is needed for EVPN multi-homing
    where a neighbor entry for a multi-homed host needs to be synced
    across all the VTEPs among which the host is multi-homed.
 
  - Support NUD_PERMANENT for proxy neighbor entries.
 
  - Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM.
 
  - Add sequence numbers to netconsole messages. Unregister netconsole's
    console when all net targets are removed. Code refactoring.
    Add a number of selftests.
 
  - Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
    should be used for an inbound SA lookup.
 
  - Support inspecting ref_tracker state via DebugFS.
 
  - Don't force bonding advertisement frames tx to ~333 ms boundaries.
    Add broadcast_neighbor option to send ARP/ND on all bonded links.
 
  - Allow providing upcall pid for the 'execute' command in openvswitch.
 
  - Remove DCCP support from Netfilter's conntrack.
 
  - Disallow multiple packet duplications in the queuing layer.
 
  - Prevent use of deprecated iptables code on PREEMPT_RT.
 
 Driver API
 ----------
 
  - Support RSS and hashing configuration over ethtool Netlink.
 
  - Add dedicated ethtool callbacks for getting and setting hashing fields.
 
  - Add support for power budget evaluation strategy in PSE /
    Power-over-Ethernet. Generate Netlink events for overcurrent etc.
 
  - Support DPLL phase offset monitoring across all device inputs.
    Support providing clock reference and SYNC over separate DPLL
    inputs.
 
  - Support traffic classes in devlink rate API for bandwidth management.
 
  - Remove rtnl_lock dependency from UDP tunnel port configuration.
 
 Device drivers
 --------------

4c10d22211 soc: defconfig updates for 6.16 
As usual, more drivers get enabled in the defconfigs, to support newly
 added hardware drivers.
 
 There is one change for Tegra that modifies the Kconfig file at the same
 time, and the NXP arm32 defconfigs get a refresh.

177bf8620c sound updates for 6.17-rc1 
This includes lots of file shuffling due to HD-audio code
 reorganization and many trivial changes, but otherwise there shouldn't
 be much surprise from the functionality POV.  The PR includes the PM
 changes as prerequisite, too.  Some highlights below:
 
 Core:
 - Performance optimizations in PCM core code
 - Refactoring of ASoC Kconfig menus to be hopefully more consistant
   and easier to navigate.
 - Refactoring of ASoC DAPM code, mainly hiding functionality that
   doesn't need to be exposed to drivers
 
 HD-audio reorganization:
 - All code are moved under sound/hda with a bit more understandable
   tree structure, as well as file renames
 - The huge Realtek driver code is split to several parts, a common
   helper module with driver modules per probe entry
 - HDMI and Cirrus codec drivers also split
 
 ASoC:
 - Further work on the generic handling for SoundWire SDCA devices
 - Support for AMD ACP7.2 and SoundWire on ACP 7.1, Fairphone 4 & 5,
   various Intel systems, Qualcomm QCS8275, Richtek RTQ9124 and TI
   TAS5753
 
 HD-audio and USB-audio:
 - TAS2781 driver cleanup and TAS2770 support
 - EQ enablement in CA0132 driver
 - USB audio quirk code cleanups
 
 Others:
 - Cleanups of PM autosuspend call patterns with the update from the PM
   tree
 - Lots of strcpy() -> strscpy() conversions for fixed size arrays

13150742b0 Crypto library updates for 6.17 
This is the main crypto library pull request for 6.17. The main focus
 this cycle is on reorganizing the SHA-1 and SHA-2 code, providing
 high-quality library APIs for SHA-1 and SHA-2 including HMAC support,
 and establishing conventions for lib/crypto/ going forward:
 
  - Migrate the SHA-1 and SHA-512 code (and also SHA-384 which shares
    most of the SHA-512 code) into lib/crypto/. This includes both the
    generic and architecture-optimized code. Greatly simplify how the
    architecture-optimized code is integrated. Add an easy-to-use
    library API for each SHA variant, including HMAC support. Finally,
    reimplement the crypto_shash support on top of the library API.
 
  - Apply the same reorganization to the SHA-256 code (and also SHA-224
    which shares most of the SHA-256 code). This is a somewhat smaller
    change, due to my earlier work on SHA-256. But this brings in all
    the same additional improvements that I made for SHA-1 and SHA-512.
 
 There are also some smaller changes:
 
  - Move the architecture-optimized ChaCha, Poly1305, and BLAKE2s code
    from arch/$(SRCARCH)/lib/crypto/ to lib/crypto/$(SRCARCH)/. For
    these algorithms it's just a move, not a full reorganization yet.
 
  - Fix the MIPS chacha-core.S to build with the clang assembler.
 
  - Fix the Poly1305 functions to work in all contexts.
 
  - Fix a performance regression in the x86_64 Poly1305 code.
 
  - Clean up the x86_64 SHA-NI optimized SHA-1 assembly code.
 
 Note that since the new organization of the SHA code is much simpler,
 the diffstat of this pull request is negative, despite the addition of
 new fully-documented library APIs for multiple SHA and HMAC-SHA
 variants. These APIs will allow further simplifications across the
 kernel as users start using them instead of the old-school crypto API.
 (I've already written a lot of such conversion patches, removing over
 1000 more lines of code. But most of those will target 6.18 or later.)

70cb6ca58f lib/crypto: arm/sha1: Migrate optimized code into library 
Instead of exposing the arm-optimized SHA-1 code via arm-specific
crypto_shash algorithms, instead just implement the sha1_blocks()
library function.  This is much simpler, it makes the SHA-1 library
functions be arm-optimized, and it fixes the longstanding issue where
the arm-optimized SHA-1 code was disabled by default.  SHA-1 still
remains available through crypto_shash, but individual architectures no
longer need to handle it.

To match sha1_blocks(), change the type of the nblocks parameter of the
assembly functions from int to size_t.  The assembly functions actually
already treated it as size_t.

fd72f265bb netfilter: conntrack: remove DCCP protocol support 
The DCCP socket family has now been removed from this tree, see:

  8bb3212be4 ("Merge branch 'net-retire-dccp-socket'")

Remove connection tracking and NAT support for this protocol, this
should not pose a problem because no DCCP traffic is expected to be seen
on the wire.

As for the code for matching on dccp header for iptables and nftables,
mark it as deprecated and keep it in place. Ruleset restoration is an
atomic operation. Without dccp matching support, an astray match on dccp
could break this operation leaving your computer with no policy in
place, so let's follow a more conservative approach for matches.

Add CONFIG_NFT_EXTHDR_DCCP which is set to 'n' by default to deprecate
dccp extension support. Similarly, label CONFIG_NETFILTER_XT_MATCH_DCCP
as deprecated too and also set it to 'n' by default.

Code to match on DCCP protocol from ebtables also remains in place, this
is just a few checks on IPPROTO_DCCP from _check() path which is
exercised when ruleset is loaded. There is another use of IPPROTO_DCCP
from the _check() path in the iptables multiport match. Another check
for IPPROTO_DCCP from the packet in the reject target is also removed.

So let's schedule removal of the dccp matching for a second stage, this
should not interfer with the dccp retirement since this is only matching
on the dccp header.

5b019bb25f crypto: stm32 - remove crc32 and crc32c support 
Remove the crc32 and crc32c support from the stm32 driver.  Since it's
not wired up to the CRC library, almost no CRC user in the kernel can
actually be taking advantage of it, so it's effectively dead code.

Support for this hardware could be migrated to the CRC library, but
there doesn't seem to be much point.  This CRC engine is present only on
a couple older SoCs that lacked CRC instructions.

Even for those SoCs, it probably wouldn't be worthwhile.  This driver
has to deal with things like locking and runtime power management that
do not exist in software CRC code and are a source of bugs (as is clear
from the commit log) and add significant overhead to the processing of
short messages, which are common.  The patch that added this driver
seemed to justify it based purely on a microbenchmark on Cortex-M7 on
long messages, not a real use case.  These days, if this driver were to
be used at all it would likely be on Cortex-A7 instead.  This CRC engine
is also not supported by QEMU, making the driver not easily testable.

500af1defb ARM: soc updates for 6.16 
The main update in size is the removal of the TI DaVinci DA830 SoC
 support. DA830 is similar to DA850, which remain supported, but
 only the reference board was ever supported, and we removed that
 one 3 years ago as it had never been converted to devicetree.
 
 There are some other cleanups for OMAP4 and a few boards using
 old GPIO interfaces.

680ef57915 mfd: sec: Split into core and transport (i2c) drivers 
As a preparation for adding support for Samsung's S2MPG10, which is
connected via SPEEDY / ACPM rather than I2C, split out (move) all
I2C-specific driver code into its own kernel module, sec-i2c, and
make the existing sec-core module be just the transport-agnostic core
driver kernel module.

At the same time, update all defconfigs that reference the old kconfig
symbol name.

While at it, also update file header comments and module description(s)
to drop references to 'mfd', and update comments to be C-style, not
C++.

The negative-sense of CRYPTO_MANAGER_DISABLE_TESTS is a longstanding

have CRYPTO=n && CRYPTO_MANAGER_DISABLE_TESTS=n, which is ambiguous.

Replace CRYPTO_MANAGER_DISABLE_TESTS with CRYPTO_SELFTESTS which has the
expected behavior.

The tests continue to be disabled by default.

ca4477e41c crypto: arm/sha256 - implement library instead of shash 
Instead of providing crypto_shash algorithms for the arch-optimized
SHA-256 code, instead implement the SHA-256 library.  This is much
simpler, it makes the SHA-256 library functions be arch-optimized, and
it fixes the longstanding issue where the arch-optimized SHA-256 was
disabled by default.  SHA-256 still remains available through
crypto_shash, but individual architectures no longer need to handle it.

To merge the scalar, NEON, and CE code all into one module cleanly, add
!CPU_V7M as a direct dependency of the CE code.  Previously, !CPU_V7M
was only a direct dependency of the scalar and NEON code.  The result is
still the same because CPU_V7M implies !KERNEL_MODE_NEON, so !CPU_V7M
was already an indirect dependency of the CE code.

To match sha256_blocks_arch(), change the type of the nblocks parameter
of the assembly functions from int to size_t.  The assembly functions
actually already treated it as size_t.

While renaming the assembly files, also fix the naming quirk where
"sha2" meant sha256.  (SHA-512 is also part of SHA-2.)

Merge tag 'drm-next-2025-03-28' of https://gitlab.freedesktop.org/drm/kernel

Pull drm updates from Dave Airlie:
 "Outside of drm there are some rust patches from Danilo who maintains
  that area in here, and some pieces for drm header check tests.

  The major things in here are a new driver supporting the touchbar
  displays on M1/M2, the nova-core stub driver which is just the vehicle
  for adding rust abstractions and start developing a real driver inside
  of.

  xe adds support for SVM with a non-driver specific SVM core
  abstraction that will hopefully be useful for other drivers, along
  with support for shrinking for TTM devices. I'm sure xe and AMD
  support new devices, but the pipeline depth on these things is hard to
  know what they end up being in the marketplace!

arm: defconfig: drop RT_GROUP_SCHED=y from bcm2835/tegra/omap2plus 
Commit 673ce00c5d ("ARM: omap2plus_defconfig: Add support for distros
with systemd") said it's because of recommendation from systemd. But
systemd changed their recommendation later.[1]

For cgroup v1, if turned on, and there's any cgroup in the "cpu" hierarchy it
needs an RT budget assigned, otherwise the processes in it will not be able to
get RT at all. The problem with RT group scheduling is that it requires the
budget assigned but there's no way we could assign a default budget, since the
values to assign are both upper and lower time limits, are absolute, and need to
be sum up to < 1 for each individal cgroup. That means we cannot really come up
with values that would work by default in the general case.[2]

For cgroup v2, it's almost unusable as well. If it turned on, the cpu controller
can only be enabled when all RT processes are in the root cgroup. But it will
lose the benefits of cgroup v2 if all RT process were placed in the same cgroup.

Red Hat, Gentoo, Arch Linux and Debian all disable it. systemd also doesn't
support it.

79fbe85a03 lib/crc32: remove obsolete CRC32 options from defconfig files 
Remove all remaining references to CONFIG_CRC32_BIT,
CONFIG_CRC32_SARWATE, CONFIG_CRC32_SLICEBY4, and CONFIG_CRC32_SLICEBY8.
These options no longer exist, now that we've standardized on a single
generic CRC32 implementation.
