8a398a0c18 appletalk: move the protocol out of tree 
AppleTalk has been removed in MacOS X 10.6 (Snow Leopard), in 2009,
according to Wikipedia. We recently got a burst of AI generated
fixes to this protocol which nobody is reviewing.

Let AppleTalk follow AX.25 and hamradio out of the Linux tree.
We we will maintain the code at: github.com/linux-netdev/mod-orphan
for anyone interested in playing with it.

Retain the uAPI for now. No strong reason, simply because I suspect
keeping it will be less controversial.

794b5e7727 bluetooth: remove all PCMCIA drivers 
PCMCIA is almost completely obsolete (the last computers supporting it
natively were from ~2009), and the general consensus [1] seems to be
that support for it should be gradually removed from the kernel.

In 2023, an initial step of removing all the PCMCIA char drivers was
taken in commit 9b12f050c7 ("char: pcmcia: remove all the drivers"),
and that has not been reverted, so it seems logical to continue this
process by removing more low-hanging fruit.

These three Bluetooth drivers have had no meaningful changes since
their status was discussed in 2022 [2], and are unlikely to have any
remaining users. The latest functional change to any of them was a
patch to bluecard_cs to fix LED blinking behavior in 2017. The other
two drivers have not had any meaningful changes made since 2007. Remove
them.

Note that even with these drivers removed, it is still possible to use
other PCMCIA Bluetooth cards that present themselves as a standard
serial port via serial_cs and hciattach while the serial_cs driver is
still present.

1967bfaf7b crypto: pcbc - Remove support for PCBC mode 
The only user of PCBC mode (Propagating Cipher Block Chaining mode) was
net/rxrpc/rxkad.c, which now uses local code instead.

While PCBC was an interesting cryptographic experiment, it has largely
been relegated to the history books and academic exercises.  It is
non-parallelizable (i.e., very slow) and doesn't actually achieve the
integrity properties it was apparently intended to achieve.

Remove support for it from the crypto API.

374efbdc85 crypto: fcrypt - Remove support for FCrypt block cipher 
Remove the insecure FCrypt block cipher from the crypto API.  Its only
user was net/rxrpc/, but now net/rxrpc/ implements it locally.  The
crypto API implementation is no longer needed.

For some additional context: FCrypt was designed in 1988 and is
essentially a weakened version of DES.  It has the same 56-bit key size
as DES, which is easily brute forced.  Moreover, it's cryptographically
weak and doesn't even provide the intended 56-bit security level.  Its
author considers it to be a mistake, as well
(https://lists.openafs.org/pipermail/openafs-devel/2000-December/005320.html).

But fortunately this 1980s-era homebrew block cipher was never adopted
outside of net/rxrpc/.  So its code can just be kept there.

160625174a char: dtlk: remove driver for ISA speech synthesizer card 
The dtlk driver supports the RC Systems DoubleTalk PC ISA speech
synthesizer card. It has severe coding style issues and has only
received tree-wide fixes and drive-by cleanups in the entire Git
history (since Linux 2.6.12-rc2). The same hardware is supported by
drivers/accessibility/speakup for screen reader use, but that
implementation does not share any code with this driver. Given all of
these factors, it is likely the driver is entirely unused. Remove it to
reduce future maintenance workload.

Note: The removed maintainer is already listed in CREDITS.

61848e9799 tty: synclink_gt: remove broken driver 
The synclink_gt driver was marked as broken in commit 426263d5fb
("tty: synclink_gt: mark as BROKEN") in July 2023 because it had severe
structural problems and there had been no evidence of users since 2016.
Since then, no meaningful improvements have been made to the driver,
and it is unlikely that will ever happen due to the lack of interest.
Drop the driver and references to it in comments and documentation.
include/uapi/linux/synclink.h is also removed. The only use of this
header I have found is the linux-raw-sys Rust crate. It generates
bindings for all UAPI headers, but has a hardcoded list of headers and
ioctls, including this one, so that does not indicate that anyone is
using it. I have sent a pull request to remove the include and ioctl
definitions for this header (see the link below).

64edfa6506 Delete some obsolete networking code 
Old code like amateur radio and NFC have long been a burden
 to core networking developers. syzbot loves to find bugs
 in BKL-era code, and 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 behind us.

aec3202247 net: packetengines: remove obsolete yellowfin driver and vendor dir 
Similar to the hamachi driver, the yellowfin driver supports hardware
that is over two decades old and no longer in active use.

Since yellowfin was the last remaining driver in the packetengines
vendor directory, we can now safely remove the entire directory and
drop its associated references from the parent Kconfig and Makefile.

This eliminates dead code and reduces the overall maintenance burden
on the netdev subsystem.

8c6d03b7a2 crypto: Remove michael_mic from crypto_shash API 
Remove the "michael_mic" crypto_shash algorithm, since it's no longer
used.  Its only users were wireless drivers, which have now been
converted to use the michael_mic() function instead.

It makes sense that no other users ever appeared: Michael MIC is an
insecure algorithm that is specific to WPA TKIP, which itself was an
interim security solution to replace the broken WEP standard.

b3c26ea81c pcmcia: remove obsolete host controller drivers 
PCMCIA is almost completely obsolete (the last computers supporting it
natively were from ~2009), and the general consensus [1] seems to be
that support for it should be gradually removed from the kernel.

In 2023, an initial step of removing all the PCMCIA char drivers was
taken in commit 9b12f050c7 ("char: pcmcia: remove all the drivers"),
and that has not been reverted, so it seems logical to continue this
process by removing more low-hanging fruit.

These host controller drivers have had no meaningful changes since
their status was discussed in 2022 [2], and are unlikely to have any
remaining users. Remove them and a couple references to them
in comments.

The i82365 and tcic drivers are for ISA-attached host controllers,
which are even less likely to be used nowadays than ones on other buses.

The i82092 driver has almost certainly not been used in over 20 years.
It was broken by a null pointer dereference since the dawn of Git
history (2.6.12-rc2 in 2005) until someone fixed it in 2021 in commit
e39cdacf2f ("pcmcia: i82092: fix a null pointer dereference bug").
From their dmesg log [3], it is clear they were testing in an emulated
environment and not on real hardware.

i82365.h is used by drivers other than i82365 and is therefore retained.

aba0138eb7 net: ethernet: neterion: s2io: remove unused driver 
The s2io driver supports Exar (formerly Neterion and S2io) PCI-X 10
Gigabit Ethernet cards. Hardware supporting PCI-X has not been
manufactured in years. On x86, it was quickly replaced by PCIe. While
it stuck around longer on POWER hardware, the last POWER hardware to
support it was POWER7, which is not supported by ppc64le Linux
distributions. The last supported mainstream ppc64 Linux distribution
was RHEL 7; while it is still supported under ELS, ELS is only
available for x86 and IBM Z. It is possible to use many PCI-X cards in
standard PCI slots (which are still available on new motherboards), but
it does not make sense to do so for 10 Gigabit Ethernet because the
maximum bandwidth of standard PCI is only 1067 Mbps. It is therefore
highly unlikely that this driver is still being used. Remove the
driver, and move the former maintainer to the CREDITS file (restoring
credit for the vxge driver, which was removed in commit f05643a0f6
("eth: remove neterion/vxge").

d30aca3eef lib/tests: convert test_min_heap module to KUnit 
Move lib/test_min_heap.c to lib/tests/min_heap_kunit.c and convert it to
use KUnit.

This change switches the ad-hoc test code to standard KUnit test cases. 
The test data remains the same, but the verification logic is updated to
use KUNIT_EXPECT_* macros.

Also remove CONFIG_TEST_MIN_HEAP from arch/*/configs/* because it is no
longer used.  The new CONFIG_MIN_HEAP_KUNIT_TEST will be automatically
enabled by CONFIG_KUNIT_ALL_TESTS.

The reasons for converting to KUnit are:

1. Standardization:
    Switching from ad-hoc printk-based reporting to the standard
    KTAP format makes it easier for CI systems to parse and report test
    results

2. Better Diagnostics:
    Using KUNIT_EXPECT_* macros automatically provides detailed
    diagnostics on failure.

3. Tooling Integration:
    It allows the test to be managed and executed using standard
    KUnit tools.

e700f5d156 watchdog: softlockup: panic when lockup duration exceeds N thresholds 
The softlockup_panic sysctl is currently a binary option: panic
immediately or never panic on soft lockups.

Panicking on any soft lockup, regardless of duration, can be overly
aggressive for brief stalls that may be caused by legitimate operations. 
Conversely, never panicking may allow severe system hangs to persist
undetected.

Extend softlockup_panic to accept an integer threshold, allowing the
kernel to panic only when the normalized lockup duration exceeds N
watchdog threshold periods.  This provides finer-grained control to
distinguish between transient delays and persistent system failures.

The accepted values are:
- 0: Don't panic (unchanged)
- 1: Panic when duration >= 1 * threshold (20s default, original behavior)
- N > 1: Panic when duration >= N * threshold (e.g., 2 = 40s, 3 = 60s.)

The original behavior is preserved for values 0 and 1, maintaining full
backward compatibility while allowing systems to tolerate brief lockups
while still catching severe, persistent hangs.

 be cooked up, while most of other changes are device-specific small
 trivial fixes.
 
 - Default disablement of the kconfig for decades old pre-release
   alsa-lib PCM API; it's only the default config value change, so
   it can't lead to any regressions for the existing setups

37d55c92e9 serial: drop SERIAL_8250_DEPRECATED_OPTIONS 
In 3.7, 8250 was unintentionally renamed to 8250_core. This happened in
the commit 835d844d1a (8250_pnp: do pnp probe before legacy probe).
This made 8250.<xxxx> module options effectively defunct. Instead,
8250_core.<xxxx> worked.

In 3.9, the commit f2b8dfd9e4 (serial: 8250: Keep 8250.<xxxx> module
options functional after driver rename) made the original options work
again by introducing a hack.

Later in 3.9, the commit 9196d8acd7 (TTY: 8250, revert module name
change) changed the module name back to 8250 (from 8250_core). Since
then, the hack was there to support the transient 8250_core.<xxxx>
options. Those were present only in the 3.7..3.9 range.

These transient options were deprecated by 9326b047e4 (TTY: 8250,
deprecated 8250_core.* options) in v3.9 too.

Now, after those 12 years, it is time to get rid of this hack
completely.

- Add a RISC-V optimized implementation of Poly1305. This code was

 - Migrate the MD5 code into lib/crypto/, and add KUnit tests for MD5.
   Yes, it's still the 90s, and several kernel subsystems are still using
   MD5 for legacy use cases. As long as that remains the case, it's
   helpful to clean it up in the same way as I've been doing for other
   algorithms. Later, I plan to convert most of these users of MD5 to use
   the new MD5 library API instead of the generic crypto API.
 
 - Simplify the organization of the ChaCha, Poly1305, BLAKE2s, and
   Curve25519 code. Consolidate these into one module per algorithm,
   and centralize the configuration and build process. This is the same
   reorganization that has already been successful for SHA-1 and SHA-2.
 
 - Remove the unused crypto_kpp API for Curve25519.
 
 - Migrate the BLAKE2s and Curve25519 self-tests to KUnit.
 
 - Always enable the architecture-optimized BLAKE2s code.
 
 Due to interdependencies between test and non-test code, both are
 included in this pull request. The broken-down diffstat is as follows:

     RISC-V Poly1305:  877 insertions(+), 1 deletion(-)
     Other:           1777 insertions(+), 3117 deletions(-)
 
 Besides the new RISC-V code which is an addition, there are quite a
 few simplifications due to the improved code organization for multiple
 algorithms, the removal of the unused crypto_kpp API for Curve25519
 and redundant tests, and the redesign of the BLAKE2s test.

Instead of exposing the powerpc-optimized MD5 code via powerpc-specific
crypto_shash algorithms, instead just implement the md5_blocks() library
function.  This is much simpler, it makes the MD5 library functions be
powerpc-optimized, and it fixes the longstanding issue where the
powerpc-optimized MD5 code was disabled by default.  MD5 still remains
available through crypto_shash, but individual architectures no longer
need to handle it.

  - 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.

6b9ae8cfaa lib/crypto: powerpc/sha1: Migrate optimized code into library 
Instead of exposing the powerpc-optimized SHA-1 code via
powerpc-specific crypto_shash algorithms, instead just implement the
sha1_blocks() library function.  This is much simpler, it makes the
SHA-1 library functions be powerpc-optimized, and it fixes the
longstanding issue where the powerpc-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.

Note: to see the diff from arch/powerpc/crypto/sha1-spe-glue.c to
lib/crypto/powerpc/sha1.h, view this commit with 'git show -M10'.

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.

a206d23340 powerpc/defconfigs: Set HZ=1000 on ppc64 and powernv defconfigs 
Commit 030bdc3fd0 ("powerpc/defconfigs: Set HZ=100 on pseries and ppc64
defconfigs") lowered CONFIG_HZ from 250 to 100, citing reduced need for a
higher tick rate due to high-resolution timers and concerns about timer
interrupt overhead and cascading effects in the timer wheel.

However, improvements have been made to the timer wheel algorithm since
then, particularly in eliminating cascading effects at the cost of minor
timekeeping inaccuracies. More details are available here
https://lwn.net/Articles/646950/. This removes the original concern about
cascading, and the reliance on high-resolution timers is not applicable
to the scheduler, which still depends on periodic ticks set by CONFIG_HZ.

With the introduction of the EEVDF scheduler, users can specify custom
slices for workloads. The default base_slice is 3ms, but with CONFIG_HZ=100
(10ms tick interval), base_slice is ineffective. Workloads like stress-ng
that do not voluntarily yield the CPU run for ~10ms before switching out.
Additionally, setting a custom slice below 3ms (e.g., 2ms) should lower
task latency, but this effect is lost due to the coarse 10ms tick.

By increasing CONFIG_HZ to 1000 (1ms tick), base_slice is properly honored,
and user-defined slices work as expected. Benchmark results support this
change:

Latency improvements in schbench with EEVDF under stress-ng-induced noise:

Scheduler       CONFIG_HZ  Custom Slice  99th Percentile Latency (µs)
--------------------------------------------------------------------
EEVDF           1000       No            0.30x
EEVDF           1000       2 ms          0.29x
EEVDF (default) 100        No            1.00x

Switching to HZ=1000 reduces the 99th percentile latency in schbench by
~70%. This improvement occurs because, with HZ=1000, stress-ng tasks run
for ~3ms before yielding, compared to ~10ms with HZ=100. As a result,
schbench gets CPU time sooner, reducing its latency.

Daytrader Performance:

Daytrader results show minor variation within standard deviation,
indicating no significant regression.

Workload (Users/Instances)  Throughput 1000HZ vs 100HZ (Std Dev%)
--------------------------------------------------------------------------
30 u, 1 i                   +3.01% (1.62%)
60 u, 1 i                   +1.46% (2.69%)
90 u, 1 i                   –1.33% (3.09%)
30 u, 2 i                   -1.20% (1.71%)
30 u, 3 i                   –0.07% (1.33%)

Avg. Response Time: No Change (=)

pgbench select queries:

Metric                         1000HZ vs 100HZ (Std Dev%)
------------------------------------------------------------------
Average TPS Change             +2.16% (1.27%)
Average Latency Change         –2.21% (1.21%)

Average TPS: Higher the better
Average Latency: Lower the better

pgbench shows both throughput and latency improvements beyond standard
deviation.

Given these results and the improvements in timer wheel implementation,
increasing CONFIG_HZ to 1000 ensures that powerpc benefits from EEVDF’s
base_slice and allows fine-tuned scheduling for latency-sensitive
workloads.

Linus Torvalds
1b98f357da Networking changes for 6.16. 
Core
 ----
 
  - Implement the Device Memory TCP transmit path, allowing zero-copy
    data transmission on top of TCP from e.g. GPU memory to the wire.
 
  - Move all the IPv6 routing tables management outside the RTNL scope,
    under its own lock and RCU. The route control path is now 3x times
    faster.
 
  - Convert queue related netlink ops to instance lock, reducing
    again the scope of the RTNL lock. This improves the control plane
    scalability.
 
  - Refactor the software crc32c implementation, removing unneeded
    abstraction layers and improving significantly the related
    micro-benchmarks.
 
  - Optimize the GRO engine for UDP-tunneled traffic, for a 10%
    performance improvement in related stream tests.
 
  - Cover more per-CPU storage with local nested BH locking; this is a
    prep work to remove the current per-CPU lock in local_bh_disable()
    on PREMPT_RT.
 
  - Introduce and use nlmsg_payload helper, combining buffer bounds
    verification with accessing payload carried by netlink messages.
 
 Netfilter
 ---------
 
  - Rewrite the procfs conntrack table implementation, improving
    considerably the dump performance. A lot of user-space tools
    still use this interface.
 
  - Implement support for wildcard netdevice in netdev basechain
    and flowtables.
 
  - Integrate conntrack information into nft trace infrastructure.
 
  - Export set count and backend name to userspace, for better
    introspection.
 
 BPF
 ---
 
  - BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops
    programs and can be controlled in similar way to traditional qdiscs
    using the "tc qdisc" command.
 
  - Refactor the UDP socket iterator, addressing long standing issues
    WRT duplicate hits or missed sockets.
 
 Protocols
 ---------
 
  - Improve TCP receive buffer auto-tuning and increase the default
    upper bound for the receive buffer; overall this improves the single
    flow maximum thoughput on 200Gbs link by over 60%.
 
  - Add AFS GSSAPI security class to AF_RXRPC; it provides transport
    security for connections to the AFS fileserver and VL server.
 
  - Improve TCP multipath routing, so that the sources address always
    matches the nexthop device.
 
  - Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS,
    and thus preventing DoS caused by passing around problematic FDs.
 
  - Retire DCCP socket. DCCP only receives updates for bugs, and major
    distros disable it by default. Its removal allows for better
    organisation of TCP fields to reduce the number of cache lines hit
    in the fast path.
 
  - Extend TCP drop-reason support to cover PAWS checks.
 
 Driver API
 ----------
 
  - Reorganize PTP ioctl flag support to require an explicit opt-in for
    the drivers, avoiding the problem of drivers not rejecting new
    unsupported flags.
 
  - Converted several device drivers to timestamping APIs.
 
  - Introduce per-PHY ethtool dump helpers, improving the support for
    dump operations targeting PHYs.
 
 Tests and tooling
 -----------------
 
  - Add support for classic netlink in user space C codegen, so that
    ynl-c can now read, create and modify links, routes addresses and
    qdisc layer configuration.
 
  - Add ynl sub-types for binary attributes, allowing ynl-c to output
    known struct instead of raw binary data, clarifying the classic
    netlink output.
 
  - Extend MPTCP selftests to improve the code-coverage.
 
  - Add tests for XDP tail adjustment in AF_XDP.
 
 New hardware / drivers
 ----------------------
 
  - OpenVPN virtual driver: offload OpenVPN data channels processing
    to the kernel-space, increasing the data transfer throughput WRT
    the user-space implementation.
 
  - Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC.
 
  - Broadcom asp-v3.0 ethernet driver.
