      Linus Torvalds authored
      Pull networking updates from Jakub Kicinski:
       "Core:
      
         - bpf:
              - allow bpf programs calling kernel functions (initially to
                reuse TCP congestion control implementations)
              - enable task local storage for tracing programs - remove the
                need to store per-task state in hash maps, and allow tracing
                programs access to task local storage previously added for
                BPF_LSM
              - add bpf_for_each_map_elem() helper, allowing programs to walk
                all map elements in a more robust and easier to verify fashion
              - sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
                redirection
              - lpm: add support for batched ops in LPM trie
              - add BTF_KIND_FLOAT support - mostly to allow use of BTF on
                s390 which has floats in its headers files
              - improve BPF syscall documentation and extend the use of kdoc
                parsing scripts we already employ for bpf-helpers
              - libbpf, bpftool: support static linking of BPF ELF files
              - improve support for encapsulation of L2 packets
      
         - xdp: restructure redirect actions to avoid a runtime lookup,
           improving performance by 4-8% in microbenchmarks
      
         - xsk: build skb by page (aka generic zerocopy xmit) - improve
           performance of software AF_XDP path by 33% for devices which don't
           need headers in the linear skb part (e.g. virtio)
      
         - nexthop: resilient next-hop groups - improve path stability on
           next-hops group changes (incl. offload for mlxsw)
      
         - ipv6: segment routing: add support for IPv4 decapsulation
      
         - icmp: add support for RFC 8335 extended PROBE messages
      
         - inet: use bigger hash table for IP ID generation
      
         - tcp: deal better with delayed TX completions - make sure we don't
           give up on fast TCP retransmissions only because driver is slow in
           reporting that it completed transmitting the original
      
         - tcp: reorder tcp_congestion_ops for better cache locality
      
         - mptcp:
              - add sockopt support for common TCP options
              - add support for common TCP msg flags
              - include multiple address ids in RM_ADDR
              - add reset option support for resetting one subflow
      
         - udp: GRO L4 improvements - improve 'forward' / 'frag_list'
           co-existence with UDP tunnel GRO, allowing the first to take place
           correctly even for encapsulated UDP traffic
      
         - micro-optimize dev_gro_receive() and flow dissection, avoid
           retpoline overhead on VLAN and TEB GRO
      
         - use less memory for sysctls, add a new sysctl type, to allow using
           u8 instead of "int" and "long" and shrink networking sysctls
      
         - veth: allow GRO without XDP - this allows aggregating UDP packets
           before handing them off to routing, bridge, OvS, etc.
      
         - allow specifing ifindex when device is moved to another namespace
      
         - netfilter:
              - nft_socket: add support for cgroupsv2
              - nftables: add catch-all set element - special element used to
                define a default action in case normal lookup missed
              - use net_generic infra in many modules to avoid allocating
                per-ns memory unnecessarily
      
         - xps: improve the xps handling to avoid potential out-of-bound
           accesses and use-after-free when XPS change race with other
           re-configuration under traffic
      
         - add a config knob to turn off per-cpu netdev refcnt to catch
           underflows in testing
      
        Device APIs:
      
         - add WWAN subsystem to organize the WWAN interfaces better and
           hopefully start driving towards more unified and vendor-
           independent APIs
      
         - ethtool:
              - add interface for reading IEEE MIB stats (incl. mlx5 and bnxt
                support)
              - allow network drivers to dump arbitrary SFP EEPROM data,
                current offset+length API was a poor fit for modern SFP which
                define EEPROM in terms of pages (incl. mlx5 support)
      
         - act_police, flow_offload: add support for packet-per-second
           policing (incl. offload for nfp)
      
         - psample: add additional metadata attributes like transit delay for
           packets sampled from switch HW (and corresponding egress and
           policy-based sampling in the mlxsw driver)
      
         - dsa: improve support for sandwiched LAGs with bridge and DSA
      
         - netfilter:
              - flowtable: use direct xmit in topologies with IP forwarding,
                bridging, vlans etc.
              - nftables: counter hardware offload support
      
         - Bluetooth:
              - improvements for firmware download w/ Intel devices
              - add support for reading AOSP vendor capabilities
              - add support for virtio transport driver
      
         - mac80211:
              - allow concurrent monitor iface and ethernet rx decap
              - set priority and queue mapping for injected frames
      
         - phy: add support for Clause-45 PHY Loopback
      
         - pci/iov: add sysfs MSI-X vector assignment interface to distribute
           MSI-X resources to VFs (incl. mlx5 support)

         - virtio:

                queues with the stack when necessary
      
         - mlx5:
