Linus Torvalds 89ed67ef12 Networking changes for 6.7.
Core & protocols
 ----------------
 
  - Support usec resolution of TCP timestamps, enabled selectively by
    a route attribute.
 
  - Defer regular TCP ACK while processing socket backlog, try to send
    a cumulative ACK at the end. Increase single TCP flow performance
    on a 200Gbit NIC by 20% (100Gbit -> 120Gbit).
 
  - The Fair Queuing (FQ) packet scheduler:
    - add built-in 3 band prio / WRR scheduling
    - support bypass if the qdisc is mostly idle (5% speed up for TCP RR)
    - improve inactive flow reporting
    - optimize the layout of structures for better cache locality
 
  - Support TCP Authentication Option (RFC 5925, TCP-AO), a more modern
    replacement for the old MD5 option.
 
  - Add more retransmission timeout (RTO) related statistics to TCP_INFO.
 
  - Support sending fragmented skbs over vsock sockets.
 
  - Make sure we send SIGPIPE for vsock sockets if socket was shutdown().
 
  - Add sysctl for ignoring lower limit on lifetime in Router
    Advertisement PIO, based on an in-progress IETF draft.
 
  - Add sysctl to control activation of TCP ping-pong mode.
 
  - Add sysctl to make connection timeout in MPTCP configurable.
 
  - Support rcvlowat and notsent_lowat on MPTCP sockets, to help apps
    limit the number of wakeups.
 
  - Support netlink GET for MDB (multicast forwarding), allowing user
    space to request a single MDB entry instead of dumping the entire
    table.
 
  - Support selective FDB flushing in the VXLAN tunnel driver.
 
  - Allow limiting learned FDB entries in bridges, prevent OOM attacks.
 
  - Allow controlling via configfs netconsole targets which were created
    via the kernel cmdline at boot, rather than via configfs at runtime.
 
  - Support multiple PTP timestamp event queue readers with different
    filters.
 
  - MCTP over I3C.
 
 BPF
 ---
 
  - Add new veth-like netdevice where BPF program defines the logic
    of the xmit routine. It can operate in L3 and L2 mode.
 
  - Support exceptions - allow asserting conditions which should
    never be true but are hard for the verifier to infer.
    With some extra flexibility around handling of the exit / failure.
    https://lwn.net/Articles/938435/
 
  - Add support for local per-cpu kptr, allow allocating and storing
    per-cpu objects in maps. Access to those objects operates on
    the value for the current CPU. This allows to deprecate local
    one-off implementations of per-CPU storage like
    BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE maps.
 
  - Extend cgroup BPF sockaddr hooks for UNIX sockets. The use case is
    for systemd to re-implement the LogNamespace feature which allows
    running multiple instances of systemd-journald to process the logs
    of different services.
 
  - Enable open-coded task_vma iteration, after maple tree conversion
    made it hard to directly walk VMAs in tracing programs.
 
  - Add open-coded task, css_task and css iterator support.
    One of the use cases is customizable OOM victim selection via BPF.
 
  - Allow source address selection with bpf_*_fib_lookup().
 
  - Add ability to pin BPF timer to the current CPU.
 
  - Prevent creation of infinite loops by combining tail calls and
    fentry/fexit programs.
 
  - Add missed stats for kprobes to retrieve the number of missed kprobe
    executions and subsequent executions of BPF programs.
 
  - Inherit system settings for CPU security mitigations.
 
  - Add BPF v4 CPU instruction support for arm32 and s390x.
 
 Changes to common code
 ----------------------
 
  - overflow: add DEFINE_FLEX() for on-stack definition of structs
    with flexible array members.
 
  - Process doc update with more guidance for reviewers.
 
 Driver API
 ----------
 
  - Simplify locking in WiFi (cfg80211 and mac80211 layers), use wiphy
    mutex in most places and remove a lot of smaller locks.
 
  - Create a common DPLL configuration API. Allow configuring
    and querying state of PLL circuits used for clock syntonization,
    in network time distribution.
 
  - Unify fragmented and full page allocation APIs in page pool code.
    Let drivers be ignorant of PAGE_SIZE.
 
  - Rework PHY state machine to avoid races with calls to phy_stop().
 
  - Notify DSA drivers of MAC address changes on user ports, improve
    correctness of offloads which depend on matching port MAC addresses.
 
  - Allow antenna control on injected WiFi frames.
 
  - Reduce the number of variants of napi_schedule().
 
  - Simplify error handling when composing devlink health messages.
 
 Misc
 ----
 
  - A lot of KCSAN data race "fixes", from Eric.
 
  - A lot of __counted_by() annotations, from Kees.
 
  - A lot of strncpy -> strscpy and printf format fixes.
 
  - Replace master/slave terminology with conduit/user in DSA drivers.
 
  - Handful of KUnit tests for netdev and WiFi core.
