Linus Torvalds 857f1268a5 Changes in this cycle were:
- Shrink 'struct instruction', to improve objtool performance & memory
    footprint.
 
  - Other maximum memory usage reductions - this makes the build both faster,
    and fixes kernel build OOM failures on allyesconfig and similar configs
    when they try to build the final (large) vmlinux.o.
 
  - Fix ORC unwinding when a kprobe (INT3) is set on a stack-modifying
    single-byte instruction (PUSH/POP or LEAVE). This requires the
    extension of the ORC metadata structure with a 'signal' field.
 
  - Misc fixes & cleanups.

Linus Torvalds f122a08b19 capability: just use a 'u64' instead of a 'u32[2]' array
Back in 2008 we extended the capability bits from 32 to 64, and we did
it by extending the single 32-bit capability word from one word to an
array of two words.  It was then obfuscated by hiding the "2" behind two
macro expansions, with the reasoning being that maybe it gets extended
further some day.

That reasoning may have been valid at the time, but the last thing we
want to do is to extend the capability set any more.  And the array of
values not only causes source code oddities (with loops to deal with
it), but also results in worse code generation.  It's a lose-lose
situation.

So just change the 'u32[2]' into a 'u64' and be done with it.

We still have to deal with the fact that the user space interface is
designed around an array of these 32-bit values, but that was the case
before too, since the array layouts were different (ie user space
doesn't use an array of 32-bit values for individual capability masks,
but an array of 32-bit slices of multiple masks).

So that marshalling of data is actually simplified too, even if it does
remain somewhat obscure and odd.

This was all triggered by my reaction to the new "cap_isidentical()"
introduced recently.  By just using a saner data structure, it went from

	unsigned __capi;
	CAP_FOR_EACH_U32(__capi) {
		if (a.cap[__capi] != b.cap[__capi])
			return false;
	}
	return true;

to just being

	return a.val == b.val;

instead.  Which is rather more obvious both to humans and to compilers.

Linus Torvalds 49d5759268 ARM:
- Provide a virtual cache topology to the guest to avoid
   inconsistencies with migration on heterogenous systems. Non secure
   software has no practical need to traverse the caches by set/way in
   the first place.
 
 - Add support for taking stage-2 access faults in parallel. This was an
   accidental omission in the original parallel faults implementation,
   but should provide a marginal improvement to machines w/o FEAT_HAFDBS
   (such as hardware from the fruit company).
 
 - A preamble to adding support for nested virtualization to KVM,
   including vEL2 register state, rudimentary nested exception handling
   and masking unsupported features for nested guests.
 
 - Fixes to the PSCI relay that avoid an unexpected host SVE trap when
   resuming a CPU when running pKVM.
 
 - VGIC maintenance interrupt support for the AIC
 
 - Improvements to the arch timer emulation, primarily aimed at reducing
   the trap overhead of running nested.
 
 - Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the
   interest of CI systems.
 
 - Avoid VM-wide stop-the-world operations when a vCPU accesses its own
   redistributor.
 
 - Serialize when toggling CPACR_EL1.SMEN to avoid unexpected exceptions
   in the host.
 
 - Aesthetic and comment/kerneldoc fixes
 
 - Drop the vestiges of the old Columbia mailing list and add [Oliver]
   as co-maintainer
 
 This also drags in arm64's 'for-next/sme2' branch, because both it and
 the PSCI relay changes touch the EL2 initialization code.
 
 RISC-V:
 
 - Fix wrong usage of PGDIR_SIZE instead of PUD_SIZE
 
 - Correctly place the guest in S-mode after redirecting a trap to the guest
 
 - Redirect illegal instruction traps to guest
 
 - SBI PMU support for guest
 
 s390:
 
 - Two patches sorting out confusion between virtual and physical
   addresses, which currently are the same on s390.
 
 - A new ioctl that performs cmpxchg on guest memory
 
 - A few fixes
 
 x86:
 
 - Change tdp_mmu to a read-only parameter
 
 - Separate TDP and shadow MMU page fault paths
 
 - Enable Hyper-V invariant TSC control
 
 - Fix a variety of APICv and AVIC bugs, some of them real-world,
   some of them affecting architecurally legal but unlikely to
   happen in practice
 
 - Mark APIC timer as expired if its in one-shot mode and the count
   underflows while the vCPU task was being migrated
 
 - Advertise support for Intel's new fast REP string features
 
 - Fix a double-shootdown issue in the emergency reboot code
 
 - Ensure GIF=1 and disable SVM during an emergency reboot, i.e. give SVM
   similar treatment to VMX
 
 - Update Xen's TSC info CPUID sub-leaves as appropriate
 
 - Add support for Hyper-V's extended hypercalls, where "support" at this
   point is just forwarding the hypercalls to userspace
 
 - Clean up the kvm->lock vs. kvm->srcu sequences when updating the PMU and
   MSR filters
 
 - One-off fixes and cleanups
 
 - Fix and cleanup the range-based TLB flushing code, used when KVM is
   running on Hyper-V
 
 - Add support for filtering PMU events using a mask.  If userspace
   wants to restrict heavily what events the guest can use, it can now
   do so without needing an absurd number of filter entries
 
 - Clean up KVM's handling of "PMU MSRs to save", especially when vPMU
   support is disabled
 
 - Add PEBS support for Intel Sapphire Rapids
 
 - Fix a mostly benign overflow bug in SEV's send|receive_update_data()
 
 - Move several SVM-specific flags into vcpu_svm
 
 x86 Intel:
 
 - Handle NMI VM-Exits before leaving the noinstr region
 
 - A few trivial cleanups in the VM-Enter flows
 
 - Stop enabling VMFUNC for L1 purely to document that KVM doesn't support
   EPTP switching (or any other VM function) for L1
 
 - Fix a crash when using eVMCS's enlighted MSR bitmaps
 
 Generic:
 
 - Clean up the hardware enable and initialization flow, which was
   scattered around multiple arch-specific hooks.  Instead, just
   let the arch code call into generic code.  Both x86 and ARM should
   benefit from not having to fight common KVM code's notion of how
   to do initialization.
 
 - Account allocations in generic kvm_arch_alloc_vm()
 
 - Fix a memory leak if coalesced MMIO unregistration fails
 
 selftests:
 
 - On x86, cache the CPU vendor (AMD vs. Intel) and use the info to emit
   the correct hypercall instruction instead of relying on KVM to patch
   in VMMCALL
 
 - Use TAP interface for kvm_binary_stats_test and tsc_msrs_test

   - Avoid VM-wide stop-the-world operations when a vCPU accesses its
     own redistributor

   - Serialize when toggling CPACR_EL1.SMEN to avoid unexpected
     exceptions in the host

   - Aesthetic and comment/kerneldoc fixes

   - Drop the vestiges of the old Columbia mailing list and add [Oliver]
     as co-maintainer

  RISC-V:

   - Fix wrong usage of PGDIR_SIZE instead of PUD_SIZE

   - Correctly place the guest in S-mode after redirecting a trap to the
     guest

   - Redirect illegal instruction traps to guest

   - SBI PMU support for guest

  s390:

   - Sort out confusion between virtual and physical addresses, which
     currently are the same on s390

   - A new ioctl that performs cmpxchg on guest memory

   - A few fixes

  x86:

   - Change tdp_mmu to a read-only parameter

   - Separate TDP and shadow MMU page fault paths

   - Enable Hyper-V invariant TSC control

   - Fix a variety of APICv and AVIC bugs, some of them real-world, some
     of them affecting architecurally legal but unlikely to happen in
     practice

   - Mark APIC timer as expired if its in one-shot mode and the count
     underflows while the vCPU task was being migrated

   - Advertise support for Intel's new fast REP string features

   - Fix a double-shootdown issue in the emergency reboot code

   - Ensure GIF=1 and disable SVM during an emergency reboot, i.e. give
     SVM similar treatment to VMX

   - Update Xen's TSC info CPUID sub-leaves as appropriate

   - Add support for Hyper-V's extended hypercalls, where "support" at
     this point is just forwarding the hypercalls to userspace

   - Clean up the kvm->lock vs. kvm->srcu sequences when updating the
     PMU and MSR filters

   - One-off fixes and cleanups

   - Fix and cleanup the range-based TLB flushing code, used when KVM is
     running on Hyper-V

   - Add support for filtering PMU events using a mask. If userspace
     wants to restrict heavily what events the guest can use, it can now
     do so without needing an absurd number of filter entries

   - Clean up KVM's handling of "PMU MSRs to save", especially when vPMU
     support is disabled

   - Add PEBS support for Intel Sapphire Rapids

   - Fix a mostly benign overflow bug in SEV's
     send|receive_update_data()

   - Move several SVM-specific flags into vcpu_svm

  x86 Intel:

   - Handle NMI VM-Exits before leaving the noinstr region

   - A few trivial cleanups in the VM-Enter flows

   - Stop enabling VMFUNC for L1 purely to document that KVM doesn't
     support EPTP switching (or any other VM function) for L1

   - Fix a crash when using eVMCS's enlighted MSR bitmaps

  Generic:

   - Clean up the hardware enable and initialization flow, which was
     scattered around multiple arch-specific hooks. Instead, just let
     the arch code call into generic code. Both x86 and ARM should
     benefit from not having to fight common KVM code's notion of how to
     do initialization

   - Account allocations in generic kvm_arch_alloc_vm()

   - Fix a memory leak if coalesced MMIO unregistration fails

  selftests:

   - On x86, cache the CPU vendor (AMD vs. Intel) and use the info to
     emit the correct hypercall instruction instead of relying on KVM to
     patch in VMMCALL

   - Use TAP interface for kvm_binary_stats_test and tsc_msrs_test"

Merge tag 'cxl-for-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

Pull Compute Express Link (CXL) updates from Dan Williams:
 "To date Linux has been dependent on platform-firmware to map CXL RAM
  regions and handle events / errors from devices. With this update we
  can now parse / update the CXL memory layout, and report events /
  errors from devices. This is a precursor for the CXL subsystem to
  handle the end-to-end "RAS" flow for CXL memory. i.e. the flow that
  for DDR-attached-DRAM is handled by the EDAC driver where it maps
  system physical address events to a field-replaceable-unit (FRU /
  endpoint device). In general, CXL has the potential to standardize
  what has historically been a pile of memory-controller-specific error
  handling logic.

  Another change of note is the default policy for handling RAM-backed
  device-dax instances. Previously the default access mode was "device",
  mmap(2) a device special file to access memory. The new default is
  "kmem" where the address range is assigned to the core-mm via
  add_memory_driver_managed(). This saves typical users from wondering
  why their platform memory is not visible via free(1) and stuck behind
  a device-file. At the same time it allows expert users to deploy
  policy to, for example, get dedicated access to high performance
  memory, or hide low performance memory from general purpose kernel
  allocations. This affects not only CXL, but also systems with
  high-bandwidth-memory that platform-firmware tags with the
  EFI_MEMORY_SP (special purpose) designation.

  Summary:

   - CXL RAM region enumeration: instantiate 'struct cxl_region' objects
     for platform firmware created memory regions

   - CXL RAM region provisioning: complement the existing PMEM region
     creation support with RAM region support

   - "Soft Reservation" policy change: Online (memory hot-add)
     soft-reserved memory (EFI_MEMORY_SP) by default, but still allow
     for setting aside such memory for dedicated access via device-dax.

   - CXL Events and Interrupts: Takeover CXL event handling from
     platform-firmware (ACPI calls this CXL Memory Error Reporting) and
     export CXL Events via Linux Trace Events.

   - Convey CXL _OSC results to drivers: Similar to PCI, let the CXL
     subsystem interrogate the result of CXL _OSC negotiation.

   - Emulate CXL DVSEC Range Registers as "decoders": Allow for
     first-generation devices that pre-date the definition of the CXL
     HDM Decoder Capability to translate the CXL DVSEC Range Registers
     into 'struct cxl_decoder' objects.

   - Set timestamp: Per spec, set the device timestamp in case of
     hotplug, or if platform-firwmare failed to set it.

   Please note that to have the -b option (BPF) working above one has to build
   with BUILD_BPF_SKEL=1.
 
   - Add more 'perf test' entries to test these new features.
 
 - Add Ian Rogers to MAINTAINERS as a perf tools reviewer.
 
 - Add support for retire latency feature (pipeline stall of a instruction
   compared to the previous one, in cycles) present on some Intel processors.
 
 - Add 'perf c2c' report option to show false sharing with adjacent cachelines, to
   be used in machines with cacheline prefetching, where accesses to a cacheline
   brings the next one too.
 
 - Skip 'perf test bpf' when the required kernel-debuginfo package isn't installed.
 
 perf script:
 
 - Add 'cgroup' field for 'perf script' output:
 
   $ perf record --all-cgroups -- true
   $ perf script -F comm,pid,cgroup
             true 337112  /user.slice/user-657345.slice/user@657345.service/...
             true 337112  /user.slice/user-657345.slice/user@657345.service/...
             true 337112  /user.slice/user-657345.slice/user@657345.service/...
             true 337112  /user.slice/user-657345.slice/user@657345.service/...
 
 - Add support for showing branch speculation information in 'perf
   script' and in the 'perf report' raw dump (-D).
 
 perf record:
 
 - Fix 'perf record' segfault with --overwrite and --max-size.
 
 Intel PT:
 
 - Add support for synthesizing "cycle" events from Intel PT traces as we
   support "instruction" events when Intel PT CYC packets are available. This
   enables much more accurate profiles than when using the regular 'perf record -e
   cycles' (the default) when the workload lasts for very short periods (<10ms).
 
 - .plt symbol handling improvements, better handling IBT (in the past
   MPX) done in the context of decoding Intel PT processor traces, IFUNC
   symbols on x86_64, static executables, understanding .plt.got symbols on
   x86_64.
 
 - Add a 'perf test' to test symbol resolution, part of the .plt
   improvements series, this tests things like symbol size in contexts
   where only the symbol start is available (kallsyms), etc.
 
 - Better handle auxtrace/Intel PT data when using pipe mode (perf record sleep 1|perf report).
 
 - Fix symbol lookup with kcore with multiple segments match stext,
   getting the symbol resolution to just show DSOs as unknown.
 
 ARM:
 
 - Timestamp improvements for ARM64 systems with ETMv4 (Embedded Trace
   Macrocell v4).
 
 - Ensure ARM64 CoreSight timestamps don't go backwards.
 
 - Document that ARM64 SPE (Statistical Profiling Extension) is used with 'perf c2c/mem'.
 
 - Add raw decoding for ARM64 SPEv1.2 previous branch address.
 
 - Update neoverse-n2-v2 ARM vendor events (JSON tables): topdown L1, TLB,
   cache, branch, PE utilization and instruction mix metrics.
 
 - Update decoder code for OpenCSD version 1.4, on ARM64 systems.
 
 - Fix command line auto-complete of CPU events on aarch64.
 
 perf test/bench:
 
 - Switch basic BPF filtering test to use syscall tracepoint to avoid the
   variable number of probes inserted when using the previous probe point
   (do_epoll_wait) that happens on different CPU architectures.
 
 - Fix DWARF unwind test by adding non-inline to expected function in a
   backtrace.
 
 - Use 'grep -c' where the longer form 'grep | wc -l' was being used.
 
 - Add getpid and execve benchmarks to 'perf bench syscall'.
 
 Miscellaneous:
 
 - Avoid d3-flame-graph package dependency in 'perf script flamegraph',
   making this feature more generally available.
 
 - Add JSON metric events to present CPI stall cycles in Power10.
 
 - Assorted improvements/refactorings on the JSON metrics parsing code.
 
 Build:
 
 - Fix 'perf probe' and 'perf test' when libtraceevent isn't linked, as
   several tests use tracepoints, those should be skipped.
 
 - More fallout fixes for the removal of tools/lib/traceevent/.
 
 - Fix build error when linking with libpfm.

     Please note that to have the -b option (BPF) working above one has
     to build with BUILD_BPF_SKEL=1.

   - Add more 'perf test' entries to test these new features.

  perf script:

   - Add 'cgroup' field for 'perf script' output:

        $ perf record --all-cgroups -- true
        $ perf script -F comm,pid,cgroup
                  true 337112  /user.slice/user-657345.slice/user@657345.service/...
                  true 337112  /user.slice/user-657345.slice/user@657345.service/...
                  true 337112  /user.slice/user-657345.slice/user@657345.service/...
                  true 337112  /user.slice/user-657345.slice/user@657345.service/...

   - Add support for showing branch speculation information in 'perf
     script' and in the 'perf report' raw dump (-D).

  perf record:

   - Fix 'perf record' segfault with --overwrite and --max-size.

  perf test/bench:

   - Switch basic BPF filtering test to use syscall tracepoint to avoid
     the variable number of probes inserted when using the previous
     probe point (do_epoll_wait) that happens on different CPU
     architectures.

   - Fix DWARF unwind test by adding non-inline to expected function in
     a backtrace.

   - Use 'grep -c' where the longer form 'grep | wc -l' was being used.

   - Add getpid and execve benchmarks to 'perf bench syscall'.

  Intel PT:

   - Add support for synthesizing "cycle" events from Intel PT traces as
     we support "instruction" events when Intel PT CYC packets are
     available. This enables much more accurate profiles than when using
     the regular 'perf record -e cycles' (the default) when the workload
     lasts for very short periods (<10ms).

   - .plt symbol handling improvements, better handling IBT (in the past
     MPX) done in the context of decoding Intel PT processor traces,
     IFUNC symbols on x86_64, static executables, understanding .plt.got
     symbols on x86_64.

   - Add a 'perf test' to test symbol resolution, part of the .plt
     improvements series, this tests things like symbol size in contexts
     where only the symbol start is available (kallsyms), etc.

   - Better handle auxtrace/Intel PT data when using pipe mode (perf
     record sleep 1|perf report).

   - Fix symbol lookup with kcore with multiple segments match stext,
     getting the symbol resolution to just show DSOs as unknown.

  ARM:

   - Timestamp improvements for ARM64 systems with ETMv4 (Embedded Trace
     Macrocell v4).

   - Ensure ARM64 CoreSight timestamps don't go backwards.

   - Document that ARM64 SPE (Statistical Profiling Extension) is used
     with 'perf c2c/mem'.

   - Add raw decoding for ARM64 SPEv1.2 previous branch address.

   - Update neoverse-n2-v2 ARM vendor events (JSON tables): topdown L1,
     TLB, cache, branch, PE utilization and instruction mix metrics.

   - Update decoder code for OpenCSD version 1.4, on ARM64 systems.

   - Fix command line auto-complete of CPU events on aarch64.

  Build:

   - Fix 'perf probe' and 'perf test' when libtraceevent isn't linked,
     as several tests use tracepoints, those should be skipped.

   - More fallout fixes for the removal of tools/lib/traceevent/.

   - Fix build error when linking with libpfm"

Linus Torvalds 192a5e0a19 LKMM updates for v6.3
Documentation updates.
 
 Add read-modify-write sequences, which means that stronger primitives
 more consistently result in stronger ordering, while still remaining in
 the envelope of the hardware that supports Linux.
 
 Address, data, and control dependencies used to ignore data that was
 stored in temporaries.  This update extends these dependency chains to
 include unmarked intra-thread stores and loads.  Note that these unmarked
 stores and loads should not be concurrently accessed from multiple
 threads, and doing so will cause LKMM to flag such accesses as data races.

Pull LKMM (Linux Kernel Memory Model) updates from Paul McKenney:
 "Documentation updates.

  Add read-modify-write sequences, which means that stronger primitives
  more consistently result in stronger ordering, while still remaining
  in the envelope of the hardware that supports Linux.

  Address, data, and control dependencies used to ignore data that was
  stored in temporaries. This update extends these dependency chains to
  include unmarked intra-thread stores and loads. Note that these
  unmarked stores and loads should not be concurrently accessed from
  multiple threads, and doing so will cause LKMM to flag such accesses
  as data races"

Josh Poimboeuf 00c8f01c4e objtool: Fix ORC 'signal' propagation
There have been some recently reported ORC unwinder warnings like:

  WARNING: can't access registers at entry_SYSCALL_64_after_hwframe+0x63/0xcd
  WARNING: stack going in the wrong direction? at __sys_setsockopt+0x2c6/0x5b0 net/socket.c:2271

And a KASAN warning:

  BUG: KASAN: stack-out-of-bounds in unwind_next_frame (arch/x86/include/asm/ptrace.h:136 arch/x86/kernel/unwind_orc.c:455)

It turns out the 'signal' bit isn't getting propagated from the unwind
hints to the ORC entries, making the unwinder confused at times.

Fixes: ffb1b4a410 ("x86/unwind/orc: Add 'signal' field to ORC metadata")

Peter Zijlstra 1c34496e58 objtool: Remove instruction::list
Replace the instruction::list by allocating instructions in arrays of
256 entries and stringing them together by (amortized) find_insn().

Peter Zijlstra a706bb08c8 objtool: Fix overlapping alternatives
Things like ALTERNATIVE_{2,3}() generate multiple alternatives on the
same place, objtool would override the first orig_alt_group with the
second (or third), failing to check the CFI among all the different
variants.

Peter Zijlstra 8b2de41215 objtool: Shrink instruction::{type,visited}
Since we don't have that many types in enum insn_type, force it into a
u8 and re-arrange member to get rid of the holes, saves another 8
bytes.

In preparation to changing struct instruction around a bit, avoid
passing it's members by pointer and instead pass the whole thing.

A cleanup in it's own right too.

Benjamin Tissoires 904e28c6de Merge branch 'for-6.3/hid-bpf' into for-linus
Initial support of HID-BPF (Benjamin Tissoires)

The history is a little long for this series, as it was intended to be
sent for v6.2. However some last minute issues forced us to postpone it
to v6.3.

Conflicts:
* drivers/hid/i2c-hid/Kconfig:
  commit bf7660dab3 ("HID: stop drivers from selecting CONFIG_HID")
  conflicts with commit 2afac81dd1 ("HID: fix I2C_HID not selected
  when I2C_HID_OF_ELAN is")
  the resolution is simple enough: just drop the "default" and "select"
  lines as the new commit from Arnd is doing
2023-02-22 10:44:31 +01:00
Linus Torvalds 5b7c4cabbb Networking changes for 6.3.
Core
 ----
 
  - Add dedicated kmem_cache for typical/small skb->head, avoid having
    to access struct page at kfree time, and improve memory use.
 
  - Introduce sysctl to set default RPS configuration for new netdevs.
 
  - Define Netlink protocol specification format which can be used
    to describe messages used by each family and auto-generate parsers.
    Add tools for generating kernel data structures and uAPI headers.
 
  - Expose all net/core sysctls inside netns.
 
  - Remove 4s sleep in netpoll if carrier is instantly detected on boot.
 
  - Add configurable limit of MDB entries per port, and port-vlan.
 
  - Continue populating drop reasons throughout the stack.
 
  - Retire a handful of legacy Qdiscs and classifiers.
 
 Protocols
 ---------
 
  - Support IPv4 big TCP (TSO frames larger than 64kB).
 
  - Add IP_LOCAL_PORT_RANGE socket option, to control local port range
    on socket by socket basis.
 
  - Track and report in procfs number of MPTCP sockets used.
 
  - Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP
    path manager.
 
  - IPv6: don't check net.ipv6.route.max_size and rely on garbage
    collection to free memory (similarly to IPv4).
 
  - Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
 
  - ICMP: add per-rate limit counters.
 
  - Add support for user scanning requests in ieee802154.
 
  - Remove static WEP support.
 
  - Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
    reporting.
 
  - WiFi 7 EHT channel puncturing support (client & AP).
 
 BPF
 ---
 
  - Add a rbtree data structure following the "next-gen data structure"
    precedent set by recently added linked list, that is, by using
    kfunc + kptr instead of adding a new BPF map type.
 
  - Expose XDP hints via kfuncs with initial support for RX hash and
    timestamp metadata.
 
  - Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key
    to better support decap on GRE tunnel devices not operating
    in collect metadata.
 
  - Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
 
  - Remove the need for trace_printk_lock for bpf_trace_printk
    and bpf_trace_vprintk helpers.
 
  - Extend libbpf's bpf_tracing.h support for tracing arguments of
    kprobes/uprobes and syscall as a special case.
 
  - Significantly reduce the search time for module symbols
    by livepatch and BPF.
 
  - Enable cpumasks to be used as kptrs, which is useful for tracing
    programs tracking which tasks end up running on which CPUs in
    different time intervals.
 
  - Add support for BPF trampoline on s390x and riscv64.
 
  - Add capability to export the XDP features supported by the NIC.
 
  - Add __bpf_kfunc tag for marking kernel functions as kfuncs.
 
  - Add cgroup.memory=nobpf kernel parameter option to disable BPF
    memory accounting for container environments.
 
 Netfilter
 ---------
 
  - Remove the CLUSTERIP target. It has been marked as obsolete
    for years, and we still have WARN splats wrt. races of
    the out-of-band /proc interface installed by this target.
 
  - Add 'destroy' commands to nf_tables. They are identical to
    the existing 'delete' commands, but do not return an error if
    the referenced object (set, chain, rule...) did not exist.
 
 Driver API
 ----------
 
  - Improve cpumask_local_spread() locality to help NICs set the right
    IRQ affinity on AMD platforms.
 
  - Separate C22 and C45 MDIO bus transactions more clearly.
 
  - Introduce new DCB table to control DSCP rewrite on egress.
 
  - Support configuration of Physical Layer Collision Avoidance (PLCA)
    Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
    shared medium Ethernet.
 
  - Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
    preemption of low priority frames by high priority frames.
 
  - Add support for controlling MACSec offload using netlink SET.
 
  - Rework devlink instance refcounts to allow registration and
    de-registration under the instance lock. Split the code into multiple
    files, drop some of the unnecessarily granular locks and factor out
    common parts of netlink operation handling.
 
  - Add TX frame aggregation parameters (for USB drivers).
 
  - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
    messages with notifications for debug.
 
  - Allow offloading of UDP NEW connections via act_ct.
 
  - Add support for per action HW stats in TC.
 
  - Support hardware miss to TC action (continue processing in SW from
    a specific point in the action chain).
 
  - Warn if old Wireless Extension user space interface is used with
    modern cfg80211/mac80211 drivers. Do not support Wireless Extensions
    for Wi-Fi 7 devices at all. Everyone should switch to using nl80211
    interface instead.
 
  - Improve the CAN bit timing configuration. Use extack to return error

Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
 "Core:

   - Add dedicated kmem_cache for typical/small skb->head, avoid having
     to access struct page at kfree time, and improve memory use.

   - Introduce sysctl to set default RPS configuration for new netdevs.

   - Define Netlink protocol specification format which can be used to
     describe messages used by each family and auto-generate parsers.
     Add tools for generating kernel data structures and uAPI headers.

   - Expose all net/core sysctls inside netns.

   - Remove 4s sleep in netpoll if carrier is instantly detected on
     boot.

   - Add configurable limit of MDB entries per port, and port-vlan.

   - Continue populating drop reasons throughout the stack.

   - Retire a handful of legacy Qdiscs and classifiers.

  Protocols:

   - Support IPv4 big TCP (TSO frames larger than 64kB).

   - Add IP_LOCAL_PORT_RANGE socket option, to control local port range
     on socket by socket basis.

   - Track and report in procfs number of MPTCP sockets used.

   - Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path
     manager.

   - IPv6: don't check net.ipv6.route.max_size and rely on garbage
     collection to free memory (similarly to IPv4).

   - Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).

   - ICMP: add per-rate limit counters.

   - Add support for user scanning requests in ieee802154.

   - Remove static WEP support.

   - Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
     reporting.

   - WiFi 7 EHT channel puncturing support (client & AP).

  BPF:

   - Add a rbtree data structure following the "next-gen data structure"
     precedent set by recently added linked list, that is, by using
     kfunc + kptr instead of adding a new BPF map type.

   - Expose XDP hints via kfuncs with initial support for RX hash and
     timestamp metadata.

   - Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to
     better support decap on GRE tunnel devices not operating in collect
     metadata.

   - Improve x86 JIT's codegen for PROBE_MEM runtime error checks.

   - Remove the need for trace_printk_lock for bpf_trace_printk and
     bpf_trace_vprintk helpers.

   - Extend libbpf's bpf_tracing.h support for tracing arguments of
     kprobes/uprobes and syscall as a special case.

   - Significantly reduce the search time for module symbols by
     livepatch and BPF.

   - Enable cpumasks to be used as kptrs, which is useful for tracing
     programs tracking which tasks end up running on which CPUs in
     different time intervals.

   - Add support for BPF trampoline on s390x and riscv64.

   - Add capability to export the XDP features supported by the NIC.

   - Add __bpf_kfunc tag for marking kernel functions as kfuncs.

   - Add cgroup.memory=nobpf kernel parameter option to disable BPF
     memory accounting for container environments.

  Netfilter:

   - Remove the CLUSTERIP target. It has been marked as obsolete for
     years, and we still have WARN splats wrt races of the out-of-band
     /proc interface installed by this target.

   - Add 'destroy' commands to nf_tables. They are identical to the
     existing 'delete' commands, but do not return an error if the
     referenced object (set, chain, rule...) did not exist.

  Driver API:

   - Improve cpumask_local_spread() locality to help NICs set the right
     IRQ affinity on AMD platforms.

   - Separate C22 and C45 MDIO bus transactions more clearly.

   - Introduce new DCB table to control DSCP rewrite on egress.

   - Support configuration of Physical Layer Collision Avoidance (PLCA)
     Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
     shared medium Ethernet.

   - Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
     preemption of low priority frames by high priority frames.

   - Add support for controlling MACSec offload using netlink SET.

   - Rework devlink instance refcounts to allow registration and
     de-registration under the instance lock. Split the code into
     multiple files, drop some of the unnecessarily granular locks and
     factor out common parts of netlink operation handling.

   - Add TX frame aggregation parameters (for USB drivers).

   - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
     messages with notifications for debug.

   - Allow offloading of UDP NEW connections via act_ct.

   - Add support for per action HW stats in TC.

   - Support hardware miss to TC action (continue processing in SW from
     a specific point in the action chain).

   - Warn if old Wireless Extension user space interface is used with
     modern cfg80211/mac80211 drivers. Do not support Wireless
     Extensions for Wi-Fi 7 devices at all. Everyone should switch to
     using nl80211 interface instead.

   - Improve the CAN bit timing configuration. Use extack to return
     error messages directly to user space, update the SJW handling,
     including the definition of a new default value that will benefit
     CAN-FD controllers, by increasing their oscillator tolerance.

Linus Torvalds 8bf1a529cd arm64 updates for 6.3:
- Support for arm64 SME 2 and 2.1. SME2 introduces a new 512-bit
   architectural register (ZT0, for the look-up table feature) that Linux
   needs to save/restore.
 
 - Include TPIDR2 in the signal context and add the corresponding
   kselftests.
 
 - Perf updates: Arm SPEv1.2 support, HiSilicon uncore PMU updates, ACPI
   support to the Marvell DDR and TAD PMU drivers, reset DTM_PMU_CONFIG
   (ARM CMN) at probe time.
 
 - Support for DYNAMIC_FTRACE_WITH_CALL_OPS on arm64.
 
 - Permit EFI boot with MMU and caches on. Instead of cleaning the entire
   loaded kernel image to the PoC and disabling the MMU and caches before
   branching to the kernel bare metal entry point, leave the MMU and
   caches enabled and rely on EFI's cacheable 1:1 mapping of all of
   system RAM to populate the initial page tables.
 
 - Expose the AArch32 (compat) ELF_HWCAP features to user in an arm64
   kernel (the arm32 kernel only defines the values).
 
 - Harden the arm64 shadow call stack pointer handling: stash the shadow
   stack pointer in the task struct on interrupt, load it directly from
   this structure.
 
 - Signal handling cleanups to remove redundant validation of size
   information and avoid reading the same data from userspace twice.
 
 - Refactor the hwcap macros to make use of the automatically generated
   ID registers. It should make new hwcaps writing less error prone.
 
 - Further arm64 sysreg conversion and some fixes.
 
 - arm64 kselftest fixes and improvements.
 
 - Pointer authentication cleanups: don't sign leaf functions, unify
   asm-arch manipulation.
 
 - Pseudo-NMI code generation optimisations.
 
 - Minor fixes for SME and TPIDR2 handling.
 
 - Miscellaneous updates: ARCH_FORCE_MAX_ORDER is now selectable, replace
   strtobool() to kstrtobool() in the cpufeature.c code, apply dynamic
   shadow call stack in two passes, intercept pfn changes in set_pte_at()
   without the required break-before-make sequence, attempt to dump all
   instructions on unhandled kernel faults.
