Problem
=========
After commit 67f69513 ("ipv6: Move setting default metric for routes"),
we noticed that the logic of assigning the default value of fc_metirc
changed in the ioctl process. That is, when users use ioctl(fd, SIOCADDRT,
rt) with a non-zero metric to add a route,  then they may fail to delete a
route with passing in a metric value of 0 to the kernel by ioctl(fd,
SIOCDELRT, rt). But iproute can succeed in deleting it.

As a reference, when using iproute tools by netlink to delete routes with
a metric parameter equals 0, like the command as follows:

	ip -6 route del fe80::/64 via fe81::5054:ff:fe11:3451 dev eth0 metric 0

the user can still succeed in deleting the route entry with the smallest
metric.

Root Reason
===========
After commit 67f69513 ("ipv6: Move setting default metric for routes"),
When ioctl() pass in SIOCDELRT with a zero metric, rtmsg_to_fib6_config()
will set a defalut value (1024) to cfg->fc_metric in kernel, and in
ip6_route_del() and the line 4074 at net/ipv3/route.c, it will check by

	if (cfg->fc_metric && cfg->fc_metric != rt->fib6_metric)
		continue;

and the condition is true and skip the later procedure (deleting route)
because cfg->fc_metric != rt->fib6_metric. But before that commit,
cfg->fc_metric is still zero there, so the condition is false and it
will do the following procedure (deleting).

Solution
========
In order to keep a consistent behaviour across netlink() and ioctl(), we
should allow to delete a route with a metric value of 0. So we only do
the default setting of fc_metric in route adding.

The qrtr protocol core logic and the qrtr nameservice are combined into
a single module. Neither the core logic or nameservice provide much
functionality by themselves; combining the two into a single module also
prevents any possible issues that may stem from client modules loading
inbetween qrtr and the ns.

Creating a socket takes two references to the module that owns the
socket protocol. Since the ns needs to create the control socket, this
creates a scenario where there are always two references to the qrtr
module. This prevents the execution of 'rmmod' for qrtr.

To resolve this, forcefully put the module refcount for the socket
opened by the nameservice.

Under some circumstances it may happen that the ks8851 Ethernet driver
stops sending data.

Currently the interrupt handler resets the interrupt status flags in the
hardware after handling TX. With this approach we may lose interrupts in
the time window between handling the TX interrupt and resetting the TX
interrupt status bit.

When all of the three following conditions are true then transmitting
data stops:

  - TX queue is stopped to wait for room in the hardware TX buffer
  - no queued SKBs in the driver (txq) that wait for being written to hw
  - hardware TX buffer is empty and the last TX interrupt was lost

This is because reenabling the TX queue happens when handling the TX
interrupt status but if the TX status bit has already been cleared then
this interrupt will never come.

With this commit the interrupt status flags will be cleared before they
are handled. That way we stop losing interrupts.

The wrong handling of the ISR flags was there from the beginning but
with commit 3dc5d445 ("net: ks8851: Fix TX stall caused by TX
buffer overrun") the issue becomes apparent.

Pull networking updates from Jakub Kicinski:
 "Core & protocols:

   - Complete rework of garbage collection of AF_UNIX sockets.

     AF_UNIX is prone to forming reference count cycles due to fd
     passing functionality. New method based on Tarjan's Strongly
     Connected Components algorithm should be both faster and remove a
     lot of workarounds we accumulated over the years.

   - Add TCP fraglist GRO support, allowing chaining multiple TCP
     packets and forwarding them together. Useful for small switches /
     routers which lack basic checksum offload in some scenarios (e.g.
     PPPoE).

   - Support using SMP threads for handling packet backlog i.e. packet
     processing from software interfaces and old drivers which don't use
     NAPI. This helps move the processing out of the softirq jumble.

   - Continue work of converting from rtnl lock to RCU protection.

     Don't require rtnl lock when reading: IPv6 routing FIB, IPv6
     address labels, netdev threaded NAPI sysfs files, bonding driver's
     sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics,
     TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot
     of the link information available via rtnetlink.

   - Small optimizations from Eric to UDP wake up handling, memory
     accounting, RPS/RFS implementation, TCP packet sizing etc.

   - Allow direct page recycling in the bulk API used by XDP, for +2%
     PPS.

   - Support peek with an offset on TCP sockets.

   - Add MPTCP APIs for querying last time packets were received/sent/acked
     and whether MPTCP "upgrade" succeeded on a TCP socket.

   - Add intra-node communication shortcut to improve SMC performance.

   - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol
     driver.

   - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.

   - Add reset reasons for tracing what caused a TCP reset to be sent.

   - Introduce direction attribute for xfrm (IPSec) states. State can be
     used either for input or output packet processing.

  Things we sprinkled into general kernel code:

   - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().

     This required touch-ups and renaming of a few existing users.

   - Add Endian-dependent __counted_by_{le,be} annotations.

   - Make building selftests "quieter" by printing summaries like
     "CC object.o" rather than full commands with all the arguments.

  Netfilter:

   - Use GFP_KERNEL to clone elements, to deal better with OOM
     situations and avoid failures in the .commit step.

  BPF:

   - Add eBPF JIT for ARCv2 CPUs.

   - Support attaching kprobe BPF programs through kprobe_multi link in
     a session mode, meaning, a BPF program is attached to both function
     entry and return, the entry program can decide if the return
     program gets executed and the entry program can share u64 cookie
     value with return program. "Session mode" is a common use-case for
     tetragon and bpftrace.

   - Add the ability to specify and retrieve BPF cookie for raw
     tracepoint programs in order to ease migration from classic to raw
     tracepoints.

   - Add an internal-only BPF per-CPU instruction for resolving per-CPU
     memory addresses and implement support in x86, ARM64 and RISC-V
     JITs. This allows inlining functions which need to access per-CPU
     state.

   - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
     atomics in bpf_arena which can be JITed as a single x86
     instruction. Support BPF arena on ARM64.

   - Add a new bpf_wq API for deferring events and refactor
     process-context bpf_timer code to keep common code where possible.

   - Harden the BPF verifier's and/or/xor value tracking.

   - Introduce crypto kfuncs to let BPF programs call kernel crypto
     APIs.

   - Support bpf_tail_call_static() helper for BPF programs with GCC 13.

   - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
     program to have code sections where preemption is disabled.

  Driver API:

   - Skip software TC processing completely if all installed rules are
     marked as HW-only, instead of checking the HW-only flag rule by
     rule.

   - Add support for configuring PoE (Power over Ethernet), similar to
     the already existing support for PoDL (Power over Data Line)
     config.

   - Initial bits of a queue control API, for now allowing a single
     queue to be reset without disturbing packet flow to other queues.

   - Common (ethtool) statistics for hardware timestamping.

  Tests and tooling:

   - Remove the need to create a config file to run the net forwarding
     tests so that a naive "make run_tests" can exercise them.

   - Define a method of writing tests which require an external endpoint
     to communicate with (to send/receive data towards the test
     machine). Add a few such tests.

   - Create a shared code library for writing Python tests. Expose the
     YAML Netlink library from tools/ to the tests for easy Netlink
     access.

   - Move netfilter tests under net/, extend them, separate performance
     tests from correctness tests, and iron out issues found by running
     them "on every commit".

   - Refactor BPF selftests to use common network helpers.

   - Further work filling in YAML definitions of Netlink messages for:
     nftables, team driver, bonding interfaces, vlan interfaces, VF
     info, TC u32 mark, TC police action.

   - Teach Python YAML Netlink to decode attribute policies.

   - Extend the definition of the "indexed array" construct in the specs
     to cover arrays of scalars rather than just nests.

   - Add hyperlinks between definitions in generated Netlink docs.

  Drivers:

   - Make sure unsupported flower control flags are rejected by drivers,
     and make more drivers report errors directly to the application
     rather than dmesg (large number of driver changes from Asbjørn
     Sloth Tønnesen).

Pull firewire updates from Takashi Sakamoto:
 "During the development period of v6.8 kernel, it became evident that
  there was a lack of helper utilities to trace the initial state of
  bus, while investigating certain PHYs compliant with different
  versions of IEEE 1394 specification.

  This series of changes includes the addition of tracepoints events,
  provided by 'firewire' subsystem. These events enable tracing of how
  firewire core functions during bus reset and asynchronous
  communication over IEEE 1394 bus.

  When implementing the tracepoints events, it was found that the
  existing serialization and deserialization helpers for several types
  of asynchronous packets are scattered across both firewire-core and
  firewire-ohci kernel modules. A set of inline functions is newly added
  to address it, along with some KUnit tests, serving as the foundation
  for the tracepoints events. This renders the dispersed code obsolete.

  The remaining changes constitute the final steps in phasing out the
  usage of deprecated PCI MSI APIs, in continuation from the previous
  version"

 - Add a dm-crypt optional "high_priority" flag that enables the crypt
   workqueues to use WQ_HIGHPRI.

 - Export dm-crypt workqueues via sysfs (by enabling WQ_SYSFS) to allow
   for improved visibility and controls over IO and crypt workqueues.

 - Fix dm-crypt to no longer constrain max_segment_size to PAGE_SIZE.
   This limit isn't needed given that the block core provides late bio
   splitting if bio exceeds underlying limits (e.g. max_segment_size).

 - Fix dm-crypt crypt_queue's use of WQ_UNBOUND to not use
   WQ_CPU_INTENSIVE because it is meaningless with WQ_UNBOUND.

Pull dlm updates from David Teigland:
 "This set includes some small fixes, and some big internal changes:

   - Fix a long standing race between the unlock callback for the last
     lkb struct, and removing the rsb that became unused after the final
     unlock. This could lead different nodes to inconsistent info about
     the rsb master node.

   - Remove unnecessary refcounting on callback structs, returning to
     the way things were done in the past.

   - Do message processing in softirq context. This allows dlm messages
     to be cleared more quickly and efficiently, reducing long lists of
     incomplete requests. A future change to run callbacks directly from
     this context will make this more effective.

   - The softirq message processing involved a number of patches
     changing mutexes to spinlocks and rwlocks, and a fair amount of
     code re-org in preparation.

   - Use an rhashtable for rsb structs, rather than our old internal
     hash table implementation. This also required some re-org of lists
     and locks preparation for the change.

   - Drop the dlm_scand kthread, and use timers to clear unused rsb
     structs. Scanning all rsb's periodically was a lot of wasted work.

 "This update brings a few minor performance improvements, otherwise
  there's a lot of refactoring, cleanups and other sort of not user
  visible changes.

  Performance improvements:

   - inline b-tree locking functions, improvement in metadata-heavy
     changes

   - relax locking on a range that's being reflinked, allows read
     operations to run in parallel

   - speed up NOCOW write checks (throughput +9% on a sample test)

   - extent locking ranges have been reduced in several places, namely
     around delayed ref processing

  Core:

   - more page to folio conversions:
      - relocation
      - send
      - compression
      - inline extent handling
      - super block write and wait

   - extent_map structure optimizations:
      - reduced structure size

      - add shrinker for allocated objects, the numbers can go high and

        not get an opportunity to be freed fast enough

   - extent locking optimizations:
      - reduce locking ranges where it does not seem to be necessary and

Pull gpio updates from Bartosz Golaszewski
 "This was a quiet release cycle for the GPIO tree and so this
  pull-request is relatively small.

  We have one new driver, some minor improvements to the GPIO core code
  and across several drivers, some DT and documentation updates but in
  general nothing stands out or is controversial. All changes have spent
  time in next with no reported issues (or ones that were quickly
  fixed).

  GPIO core:
   - remove more unused legacy interfaces (after converting the last
     remaining users to better alternatives)
   - update kerneldocs
   - improve error handling and log messages in GPIO ACPI code
   - remove dead code (always true checks) from GPIOLIB

  New drivers:
   - add a driver for Intel Granite Rapids-D vGPIO

  Driver improvements:
   - use -ENOTSUPP consistently in gpio-regmap and gpio-pcie-idio-24
   - provide an ID table for gpio-cros-ec to avoid a driver name
     fallback check
   - add support for gpio-ranges for GPIO drivers supporting multiple
     GPIO banks
   - switch to using dynamic GPIO base in gpio-brcmstb
   - fix irq handling in gpio-npcm-sgpio
   - switch to memory mapped IO accessors in gpio-sch

  DT bindings:
   - add support for gpio-ranges to gpio-brcmstb
   - add support for a new model and the gpio-line-names property to
     gpio-mpfs

  Documentation:
   - replace leading tabs with spaces in code blocks
   - fix typos"

Pull pwm updates from Uwe Kleine-König:
 "Apart for the normal updates for dt bindings, cleanups and support for
  new device variants to existing drivers this completes the conversion
  to pwmchip_alloc() which was started in the v6.9 development cycle.

  Using pwmchip_alloc() is a precondition to the character device
  support which allows easier and faster access to PWM devices. However
  there are some issues I want to clean up before including it in
  mainline, so this isn't contained here despite it was in next for some
  time.

  Thanks to Alexandre Mergnat, Binbin Zhou, Dmitry Rokosov, George
  Stark, Jerome Brunet and Varshini Rajendran for their contributions.
  Further thanks go to AngeloGioacchino Del Regno, Conor Dooley, David
  Lechner, Fabrice Gasnier, Florian Fainelli, Guenter Roeck, Gustavo A.
  R. Silva, Krzysztof Kozlowski and Rob Herring for valuable patch

Pull regulator updates from Mark Brown:
 "There's one API update here, a new API factoring out a common pattern
  for reference voltage supplies. These are supplies used as a reference
  by analogue circuits where the consumer requests and enables the
  supply, reads the voltage to calibrate the user and then never touches
  it again. This is factored out into a single operation which just
  returns the voltage and uses devm_ to manage the request and enable
  portion.

  Otherwise this has been a very quiet release, we've got some new
  device support, some small fixes, housekeeping and cleanup work but
  nothing substantial.

  There's also some non-regulator changes in here, a number of users for
  the new reference voltage API were merged along with it and some MFD
  changes were pulled in as dependencies for new driver work.

  Highlights:

   - Add a new API for single operation handling of reference voltages

   - Support for Allwinner AXP717 and D1, and NXP PCA9561A"
