Linus Torvalds bd6c11bc43 Networking changes for 6.6.
Core
 ----
 
  - Increase size limits for to-be-sent skb frag allocations. This
    allows tun, tap devices and packet sockets to better cope with large
    writes operations.
 
  - Store netdevs in an xarray, to simplify iterating over netdevs.
 
  - Refactor nexthop selection for multipath routes.
 
  - Improve sched class lifetime handling.
 
  - Add backup nexthop ID support for bridge.
 
  - Implement drop reasons support in openvswitch.
 
  - Several data races annotations and fixes.
 
  - Constify the sk parameter of routing functions.
 
  - Prepend kernel version to netconsole message.
 
 Protocols
 ---------
 
  - Implement support for TCP probing the peer being under memory
    pressure.
 
  - Remove hard coded limitation on IPv6 specific info placement
    inside the socket struct.
 
  - Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated
    per socket scaling factor.
 
  - Scaling-up the IPv6 expired route GC via a separated list of
    expiring routes.
 
  - In-kernel support for the TLS alert protocol.
 
  - Better support for UDP reuseport with connected sockets.
 
  - Add NEXT-C-SID support for SRv6 End.X behavior, reducing the SR
    header size.
 
  - Get rid of additional ancillary per MPTCP connection struct socket.
 
  - Implement support for BPF-based MPTCP packet schedulers.
 
  - Format MPTCP subtests selftests results in TAP.
 
  - Several new SMC 2.1 features including unique experimental options,
    max connections per lgr negotiation, max links per lgr negotiation.
 
 BPF
 ---
 
  - Multi-buffer support in AF_XDP.
 
  - Add multi uprobe BPF links for attaching multiple uprobes
    and usdt probes, which is significantly faster and saves extra fds.
 
  - Implement an fd-based tc BPF attach API (TCX) and BPF link support on
    top of it.
 
  - Add SO_REUSEPORT support for TC bpf_sk_assign.
 
  - Support new instructions from cpu v4 to simplify the generated code and
    feature completeness, for x86, arm64, riscv64.
 
  - Support defragmenting IPv(4|6) packets in BPF.
 
  - Teach verifier actual bounds of bpf_get_smp_processor_id()
    and fix perf+libbpf issue related to custom section handling.
 
  - Introduce bpf map element count and enable it for all program types.
 
  - Add a BPF hook in sys_socket() to change the protocol ID
    from IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy.
 
  - Introduce bpf_me_mcache_free_rcu() and fix OOM under stress.
 
  - Add uprobe support for the bpf_get_func_ip helper.
 
  - Check skb ownership against full socket.
 
  - Support for up to 12 arguments in BPF trampoline.
 
  - Extend link_info for kprobe_multi and perf_event links.
 
 Netfilter
 ---------
 
  - Speed-up process exit by aborting ruleset validation if a
    fatal signal is pending.
 
  - Allow NLA_POLICY_MASK to be used with BE16/BE32 types.
 
 Driver API
 ----------
 
  - Page pool optimizations, to improve data locality and cache usage.
 
  - Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the need
    for raw ioctl() handling in drivers.
 
  - Simplify genetlink dump operations (doit/dumpit) providing them
    the common information already populated in struct genl_info.
 
  - Extend and use the yaml devlink specs to [re]generate the split ops.
 
  - Introduce devlink selective dumps, to allow SF filtering SF based on
    handle and other attributes.
 
  - Add yaml netlink spec for netlink-raw families, allow route, link and
    address related queries via the ynl tool.
 
  - Remove phylink legacy mode support.
 
  - Support offload LED blinking to phy.
 
  - Add devlink port function attributes for IPsec.
