      Pull networking updates from Jakub Kicinski:
       "The sprinkling of SPI drivers is because we added a new one and Mark
        sent us a SPI driver interface conversion pull request.
      
        Core
        ----
      
         - Introduce XDP multi-buffer support, allowing the use of XDP with
           jumbo frame MTUs and combination with Rx coalescing offloads (LRO).
      
         - Speed up netns dismantling (5x) and lower the memory cost a little.
           Remove unnecessary per-netns sockets. Scope some lists to a netns.
           Cut down RCU syncing. Use batch methods. Allow netdev registration
           to complete out of order.
      
         - Support distinguishing timestamp types (ingress vs egress) and
           maintaining them across packet scrubbing points (e.g. redirect).
      
         - Continue the work of annotating packet drop reasons throughout the
           stack.
      
         - Switch netdev error counters from an atomic to dynamically
           allocated per-CPU counters.
      
         - Rework a few preempt_disable(), local_irq_save() and busy waiting
           sections problematic on PREEMPT_RT.
      
         - Extend the ref_tracker to allow catching use-after-free bugs.
      
        BPF
        ---
      
         - Introduce "packing allocator" for BPF JIT images. JITed code is
           marked read only, and used to be allocated at page granularity.
           Custom allocator allows for more efficient memory use, lower iTLB
           pressure and prevents identity mapping huge pages from getting
           split.
      
         - Make use of BTF type annotations (e.g. __user, __percpu) to enforce
           the correct probe read access method, add appropriate helpers.
      
         - Convert the BPF preload to use light skeleton and drop the
           user-mode-driver dependency.
      
         - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
           its use as a packet generator.
      
         - Allow local storage memory to be allocated with GFP_KERNEL if
           called from a hook allowed to sleep.
      
         - Introduce fprobe (multi kprobe) to speed up mass attachment (arch
           bits to come later).
      
         - Add unstable conntrack lookup helpers for BPF by using the BPF
           kfunc infra.
      
         - Allow cgroup BPF progs to return custom errors to user space.
      
         - Add support for AF_UNIX iterator batching.
      
         - Allow iterator programs to use sleepable helpers.
      
         - Support JIT of add, and, or, xor and xchg atomic ops on arm64.
      
         - Add BTFGen support to bpftool which allows to use CO-RE in kernels
           without BTF info.
      
         - Large number of libbpf API improvements, cleanups and deprecations.
      
        Protocols
        ---------
      
         - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.
      
         - Adjust TSO packet sizes based on min_rtt, allowing very low latency
           links (data centers) to always send full-sized TSO super-frames.
      
         - Make IPv6 flow label changes (AKA hash rethink) more configurable,
           via sysctl and setsockopt. Distinguish between server and client
           behavior.
      
         - VxLAN support to "collect metadata" devices to terminate only
           configured VNIs. This is similar to VLAN filtering in the bridge.
      
         - Support inserting IPv6 IOAM information to a fraction of frames.
      
         - Add protocol attribute to IP addresses to allow identifying where
           given address comes from (kernel-generated, DHCP etc.)
      
         - Support setting socket and IPv6 options via cmsg on ping6 sockets.
      
         - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
           Define dscp_t and stop taking ECN bits into account in fib-rules.
      
         - Add support for locked bridge ports (for 802.1X).
      
         - tun: support NAPI for packets received from batched XDP buffs,
           doubling the performance in some scenarios.
      
         - IPv6 extension header handling in Open vSwitch.
      
         - Support IPv6 control message load balancing in bonding, prevent
           neighbor solicitation and advertisement from using the wrong port.
           Support NS/NA monitor selection similar to existing ARP monitor.
      
         - SMC
            - improve performance with TCP_CORK and sendfile()
            - support auto-corking
            - support TCP_NODELAY
      
         - MCTP (Management Component Transport Protocol)
            - add user space tag control interface
            - I2C binding driver (as specified by DMTF DSP0237)
      
         - Multi-BSSID beacon handling in AP mode for WiFi.
      
         - Bluetooth:
            - handle MSFT Monitor Device Event
            - add MGMT Adv Monitor Device Found/Lost events
      
         - Multi-Path TCP:
            - add support for the SO_SNDTIMEO socket option
            - lots of selftest cleanups and improvements
      
         - Increase the max PDU size in CAN ISOTP to 64 kB.
      
        Driver API
        ----------
      
         - Add HW counters for SW netdevs, a mechanism for devices which
           offload packet forwarding to report packet statistics back to
           software interfaces such as tunnels.
      
         - Select the default NIC queue count as a fraction of number of
           physical CPU cores, instead of hard-coding to 8.
      
         - Expose devlink instance locks to drivers. Allow device layer of
           drivers to use that lock directly instead of creating their own
           which always runs into ordering issues in devlink callbacks.
      
         - Add header/data split indication to guide user space enabling of
           TCP zero-copy Rx.
      
         - Allow configuring completion queue event size.
      
         - Refactor page_pool to enable fragmenting after allocation.
      
         - Add allocation and page reuse statistics to page_pool.
      
         - Improve Multiple Spanning Trees support in the bridge to allow
           reuse of topologies across VLANs, saving HW resources in switches.
      
         - DSA (Distributed Switch Architecture):
            - replay and offload of host VLAN entries
            - offload of static and local FDB entries on LAG interfaces
            - FDB isolation and unicast filtering

         - Better API to disable virtualization quirks
      
         - Fixes and optimizations for the zapping of page tables:
      
            - Zap roots in two passes, avoiding RCU read-side critical
              sections that last too long for very large guests backed by 4
              KiB SPTEs.
      
            - Zap invalid and defunct roots asynchronously via
              concurrency-managed work queue.
      
            - Allowing yielding when zapping TDP MMU roots in response to the
              root's last reference being put.
      
            - Batch more TLB flushes with an RCU trick. Whoever frees the
              paging structure now holds RCU as a proxy for all vCPUs running
              in the guest, i.e. to prolongs the grace period on their behalf.
              It then kicks the the vCPUs out of guest mode before doing
              rcu_read_unlock().

      Pull tasklist_lock optimizations from Eric Biederman:
       "prlimit and getpriority tasklist_lock optimizations
      
        The tasklist_lock popped up as a scalability bottleneck on some
        testing workloads. The readlocks in do_prlimit and set/getpriority are
        not necessary in all cases.
      
        Based on a cycles profile, it looked like ~87% of the time was spent
        in the kernel, ~42% of which was just trying to get *some* spinlock
        (queued_spin_lock_slowpath, not necessarily the tasklist_lock).
      
        The big offenders (with rough percentages in cycles of the overall
        trace):
         - do_wait 11%
         - setpriority 8% (done previously in commit 7f8ca0ed)
         - kill 8%
         - do_exit 5%
         - clone 3%
         - prlimit64 2%   (this patchset)
         - getrlimit 1%   (this patchset)
      
        I can't easily test this patchset on the original workload for various
        reasons. Instead, I used the microbenchmark below to at least verify
        there was some improvement. This patchset had a 28% speedup (12% from
        baseline to set/getprio, then another 14% for prlimit).
      
        This series used to do the setpriority case, but an almost identical
        change was merged as commit 7f8ca0ed ("kernel/sys.c: only take
        tasklist_lock for get/setpriority(PRIO_PGRP)") so that has been
        dropped from here.
      
        One interesting thing is that my libc's getrlimit() was calling
        prlimit64, so hoisting the read_lock(tasklist_lock) into sys_prlimit64
        had no effect - it essentially optimized the older syscalls only. I
        didn't do that in this patchset, but figured I'd mention it since it
        was an option from the previous patch's discussion"

       "There are three sets of updates for 5.18 in the asm-generic tree:
      
         - The set_fs()/get_fs() infrastructure gets removed for good.
      
           This was already gone from all major architectures, but now we can
           finally remove it everywhere, which loses some particularly tricky
           and error-prone code. There is a small merge conflict against a
           parisc cleanup, the solution is to use their new version.
      
         - The nds32 architecture ends its tenure in the Linux kernel.
      
           The hardware is still used and the code is in reasonable shape, but
           the mainline port is not actively maintained any more, as all
           remaining users are thought to run vendor kernels that would never
           be updated to a future release.

         - Support for IRQ and vmap'ed stacks
      
           This covers all the work related to implementing IRQ stacks and
           vmap'ed stacks for all 32-bit ARM systems that are currently
           supported by the Linux kernel, including RiscPC and Footbridge. It
           has been submitted for review in four different waves:
      
            - IRQ stacks support for v7 SMP systems [0]
      
            - vmap'ed stacks support for v7 SMP systems[1]

              remaining configurations, including v6/v7 SMP multiplatform
              kernels and uniprocessor configurations including v7-M [2]
      
            - fixes and updates in [3]
      
         - ftrace fixes and cleanups
      
           Make all flavors of ftrace available on all builds, regardless of
           ISA choice, unwinder choice or compiler [4]:
      
            - use ADD not POP where possible
      
            - fix a couple of Thumb2 related issues
      
            - enable HAVE_FUNCTION_GRAPH_FP_TEST for robustness

      Linus Torvalds authored
      Pull tracing updates from Steven Rostedt:
      
       - New user_events interface. User space can register an event with the
         kernel describing the format of the event. Then it will receive a
         byte in a page mapping that it can check against. A privileged task
         can then enable that event like any other event, which will change
         the mapped byte to true, telling the user space application to start
         writing the event to the tracing buffer.
      
       - Add new "ftrace_boot_snapshot" kernel command line parameter. When
         set, the tracing buffer will be saved in the snapshot buffer at boot
         up when the kernel hands things over to user space. This will keep
         the traces that happened at boot up available even if user space boot
         up has tracing as well.
      
       - Have TRACE_EVENT_ENUM() also update trace event field type
         descriptions. Thus if a static array defines its size with an enum,
         the user space trace event parsers can still know how to parse that
         array.
      
       - Add new TRACE_CUSTOM_EVENT() macro. This acts the same as the
         TRACE_EVENT() macro, but will attach to an existing tracepoint. This
         will make one tracepoint be able to trace different content and not
         be stuck at only what the original TRACE_EVENT() macro exports.
      
       - Fixes to tracing error logging.
      
       - Better saving of cmdlines to PIDs when tracing (use the wakeup events
         for mapping).

      drivers: ethernet: cpsw: fix panic when interrupt coaleceing is set via ethtool · 2844e243
      Sondhauß, Jan authored
      cpsw_ethtool_begin directly returns the result of pm_runtime_get_sync
      when successful.
      pm_runtime_get_sync returns -error code on failure and 0 on successful
      resume but also 1 when the device is already active. So the common case
      for cpsw_ethtool_begin is to return 1. That leads to inconsistent calls
      to pm_runtime_put in the call-chain so that pm_runtime_put is called
      one too many times and as result leaving the cpsw dev behind suspended.
      
      The suspended cpsw dev leads to an access violation later on by
      different parts of the cpsw driver.
      
      Fix this by calling the return-friendly pm_runtime_resume_and_get
      function.

      ice: don't allow to run ice_send_event_to_aux() in atomic ctx · 5a315693
      Alexander Lobakin authored
      ice_send_event_to_aux() eventually descends to mutex_lock()
      (-> might_sched()), so it must not be called under non-task
      context. However, at least two fixes have happened already for the
      bug splats occurred due to this function being called from atomic
      context.
      To make the emergency landings softer, bail out early when executed
      in non-task context emitting a warn splat only once. This way we
      trade some events being potentially lost for system stability and
      avoid any related hangs and crashes.

      ice: fix 'scheduling while atomic' on aux critical err interrupt · 32d53c0a

      There's a kernel BUG splat on processing aux critical error
      interrupts in ice_misc_intr():

      As Andrew correctly mentioned previously[0], the following call
      ladder happens:
      
      ice_misc_intr() <- hardirq
        ice_send_event_to_aux()
          device_lock()
            mutex_lock()
              might_sleep()
                might_resched() <- oops
      
      Add a new PF state bit which indicates that an aux critical error
      occurred and serve it in ice_service_task() in process context.
      The new ice_pf::oicr_err_reg is read-write in both hardirq and
      process contexts, but only 3 bits of non-critical data probably
      aren't worth explicit synchronizing (and they're even in the same
      byte [31:24]).

      net/sched: fix incorrect vlan_push_eth dest field · 054d5575
      Louis Peens authored
      Seems like a potential copy-paste bug slipped in here,
      the second memcpy should of course be populating src
      and not dest.

      net: bridge: mst: Restrict info size queries to bridge ports · a911ad18
      Tobias Waldekranz authored
      Ensure that no bridge masters are ever considered for MST info
      dumping. MST states are only supported on bridge ports, not bridge
      masters - which br_mst_info_size relies on.
