Merge tag 'net-next-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
 "Core:

   - support "prefer busy polling" NAPI operation mode, where we defer
     softirq for some time expecting applications to periodically busy
     poll

   - AF_XDP: improve efficiency by more batching and hindering the
     adjacency cache prefetcher

   - af_packet: make packet_fanout.arr size configurable up to 64K

   - tcp: optimize TCP zero copy receive in presence of partial or
     unaligned reads making zero copy a performance win for much smaller
     messages

   - XDP: add bulk APIs for returning / freeing frames

   - sched: support fragmenting IP packets as they come out of conntrack

   - net: allow virtual netdevs to forward UDP L4 and fraglist GSO skbs

  BPF:

   - BPF switch from crude rlimit-based to memcg-based memory accounting

   - BPF type format information for kernel modules and related tracing
     enhancements

   - BPF implement task local storage for BPF LSM

   - allow the FENTRY/FEXIT/RAW_TP tracing programs to use
     bpf_sk_storage

  Protocols:

   - mptcp: improve multiple xmit streams support, memory accounting and
     many smaller improvements

   - TLS: support CHACHA20-POLY1305 cipher

   - seg6: add support for SRv6 End.DT4/DT6 behavior

   - sctp: Implement RFC 6951: UDP Encapsulation of SCTP

   - ppp_generic: add ability to bridge channels directly

   - bridge: Connectivity Fault Management (CFM) support as is defined
     in IEEE 802.1Q section 12.14.

  Drivers:

   - mlx5: make use of the new auxiliary bus to organize the driver
     internals

   - mlx5: more accurate port TX timestamping support

   - mlxsw:
      - improve the efficiency of offloaded next hop updates by using
        the new nexthop object API
      - support blackhole nexthops
      - support IEEE 802.1ad (Q-in-Q) bridging

   - rtw88: major bluetooth co-existance improvements

   - iwlwifi: support new 6 GHz frequency band

   - ath11k: Fast Initial Link Setup (FILS)

   - mt7915: dual band concurrent (DBDC) support

   - net: ipa: add basic support for IPA v4.5

  Refactor:

   - a few pieces of in_interrupt() cleanup work from Sebastian Andrzej
     Siewior

   - phy: add support for shared interrupts; get rid of multiple driver
     APIs and have the drivers write a full IRQ handler, slight growth
     of driver code should be compensated by the simpler API which also
     allows shared IRQs

   - add common code for handling netdev per-cpu counters

   - move TX packet re-allocation from Ethernet switch tag drivers to a
     central place

   - improve efficiency and rename nla_strlcpy

   - number of W=1 warning cleanups as we now catch those in a patchwork
     build bot

  Old code removal:

   - wan: delete the DLCI / SDLA drivers

   - wimax: move to staging

   - wifi: remove old WDS wifi bridging support"

+# AF_XDP is an address family optimized for high performance packet processing,
+# it is XDP’s user-space interface.
+#
+# An AF_XDP socket is linked to a single UMEM which is a region of virtual
+# contiguous memory, divided into equal-sized frames.
+#
+# Refer to AF_XDP Kernel Documentation for detailed information:
+# https://www.kernel.org/doc/html/latest/networking/af_xdp.html
+#
+# Prerequisites setup by script:
+#
+#   Set up veth interfaces as per the topology shown ^^:
+#   * setup two veth interfaces and one namespace
+#   ** veth<xxxx> in root namespace
+#   ** veth<yyyy> in af_xdp<xxxx> namespace
+#   ** namespace af_xdp<xxxx>
+#   * create a spec file veth.spec that includes this run-time configuration
+#   *** xxxx and yyyy are randomly generated 4 digit numbers used to avoid
+#       conflict with any existing interface
+#   * tests the veth and xsk layers of the topology
+#
+# See the source xdpxceiver.c for information on each test
+#
+# Kernel configuration:
+# ---------------------
+# See "config" file for recommended kernel config options.
+#
+# Turn on XDP sockets and veth support when compiling i.e.
+# 	Networking support -->
+# 		Networking options -->
+# 			[ * ] XDP sockets
+#
+# Executing Tests:
+# ----------------
+# Must run with CAP_NET_ADMIN capability.

+# Run (full color-coded output):
+#   sudo ./test_xsk.sh -c
+#

+ * Some functions in this program are taken from
+ * Linux kernel samples/bpf/xdpsock* and modified
+ * for use.
+ *
+ * See test_xsk.sh for detailed information on test topology
+ * and prerequisite network setup.
+ *
+ * This test program contains two threads, each thread is single socket with
+ * a unique UMEM. It validates in-order packet delivery and packet content
+ * by sending packets to each other.
+ *
+ * Tests Information:
+ * ------------------
+ * These selftests test AF_XDP SKB and Native/DRV modes using veth
+ * Virtual Ethernet interfaces.
+ *
+ * The following tests are run:
+ *
+ * 1. AF_XDP SKB mode
+ *    Generic mode XDP is driver independent, used when the driver does
+ *    not have support for XDP. Works on any netdevice using sockets and
+ *    generic XDP path. XDP hook from netif_receive_skb().
+ *    a. nopoll - soft-irq processing
+ *    b. poll - using poll() syscall
+ *    c. Socket Teardown
+ *       Create a Tx and a Rx socket, Tx from one socket, Rx on another. Destroy
+ *       both sockets, then repeat multiple times. Only nopoll mode is used
+ *    d. Bi-directional sockets
+ *       Configure sockets as bi-directional tx/rx sockets, sets up fill and
+ *       completion rings on each socket, tx/rx in both directions. Only nopoll
+ *       mode is used
+ *
+ * 2. AF_XDP DRV/Native mode
+ *    Works on any netdevice with XDP_REDIRECT support, driver dependent. Processes
+ *    packets before SKB allocation. Provides better performance than SKB. Driver
+ *    hook available just after DMA of buffer descriptor.
+ *    a. nopoll
+ *    b. poll
+ *    c. Socket Teardown
+ *    d. Bi-directional sockets
+ *    - Only copy mode is supported because veth does not currently support
+ *      zero-copy mode
+ *
+ * Total tests: 8
+ *
+ * Flow:
+ * -----
+ * - Single process spawns two threads: Tx and Rx
+ * - Each of these two threads attach to a veth interface within their assigned
+ *   namespaces
+ * - Each thread Creates one AF_XDP socket connected to a unique umem for each
+ *   veth interface
+ * - Tx thread Transmits 10k packets from veth<xxxx> to veth<yyyy>
+ * - Rx thread verifies if all 10k packets were received and delivered in-order,
+ *   and have the right content
+ *
+ * Enable/disable debug mode:
+ * --------------------------
+ * To enable L2 - L4 headers and payload dump of each packet on STDOUT, add
+ * parameter -D to params array in test_xsk.sh, i.e. params=("-S" "-D")

+# Test various bareudp tunnel configurations.
+#
+# The bareudp module allows to tunnel network protocols like IP or MPLS over
+# UDP, without adding any intermediate header. This scripts tests several
+# configurations of bareudp (using IPv4 or IPv6 as underlay and transporting
+# IPv4, IPv6 or MPLS packets on the overlay).
+#
+# Network topology:
+#
+#   * A chain of 4 network namespaces, connected with veth pairs. Each veth
+#     is assigned an IPv4 and an IPv6 address. A host-route allows a veth to
+#     join its peer.
+#
+#   * NS0 and NS3 are at the extremities of the chain. They have additional
+#     IPv4 and IPv6 addresses on their loopback device. Routes are added in NS0
+#     and NS3, so that they can communicate using these overlay IP addresses.
+#     For IPv4 and IPv6 reachability tests, the route simply sets the peer's
+#     veth address as gateway. For MPLS reachability tests, an MPLS header is
+#     also pushed before the IP header.
+#
+#   * NS1 and NS2 are the intermediate namespaces. They use a bareudp device to
+#     encapsulate the traffic into UDP.

+# This test is designed for evaluating the new SRv6 End.DT4 behavior used for
+# implementing IPv4 L3 VPN use cases.
+#
+# Hereafter a network diagram is shown, where two different tenants (named 100
+# and 200) offer IPv4 L3 VPN services allowing hosts to communicate with each
+# other across an IPv6 network.
+#
+# Only hosts belonging to the same tenant (and to the same VPN) can communicate
+# with each other. Instead, the communication among hosts of different tenants
+# is forbidden.
+# In other words, hosts hs-t100-1 and hs-t100-2 are connected through the IPv4
+# L3 VPN of tenant 100 while hs-t200-3 and hs-t200-4 are connected using the
+# IPv4 L3 VPN of tenant 200. Cross connection between tenant 100 and tenant 200
+# is forbidden and thus, for example, hs-t100-1 cannot reach hs-t200-3 and vice
+# versa.
+#
+# Routers rt-1 and rt-2 implement IPv4 L3 VPN services leveraging the SRv6
+# architecture. The key components for such VPNs are: a) SRv6 Encap behavior,
+# b) SRv6 End.DT4 behavior and c) VRF.
+#
+# To explain how an IPv4 L3 VPN based on SRv6 works, let us briefly consider an
+# example where, within the same domain of tenant 100, the host hs-t100-1 pings
+# the host hs-t100-2.
+#
+# First of all, L2 reachability of the host hs-t100-2 is taken into account by
+# the router rt-1 which acts as an arp proxy.
+#
+# When the host hs-t100-1 sends an IPv4 packet destined to hs-t100-2, the
+# router rt-1 receives the packet on the internal veth-t100 interface. Such
+# interface is enslaved to the VRF vrf-100 whose associated table contains the
+# SRv6 Encap route for encapsulating any IPv4 packet in a IPv6 plus the Segment
+# Routing Header (SRH) packet. This packet is sent through the (IPv6) core
+# network up to the router rt-2 that receives it on veth0 interface.
+#
+# The rt-2 router uses the 'localsid' routing table to process incoming
+# IPv6+SRH packets which belong to the VPN of the tenant 100. For each of these
+# packets, the SRv6 End.DT4 behavior removes the outer IPv6+SRH headers and
+# performs the lookup on the vrf-100 table using the destination address of
+# the decapsulated IPv4 packet. Afterwards, the packet is sent to the host
+# hs-t100-2 through the veth-t100 interface.
+#
+# The ping response follows the same processing but this time the role of rt-1
+# and rt-2 are swapped.
+#
+# Of course, the IPv4 L3 VPN for tenant 200 works exactly as the IPv4 L3 VPN
+# for tenant 100. In this case, only hosts hs-t200-3 and hs-t200-4 are able to
+# connect with each other.

+# and 200) offer IPv6 L3 VPN services allowing hosts to communicate with each
+# other across an IPv6 network.
+#
+# Only hosts belonging to the same tenant (and to the same VPN) can communicate
+# with each other. Instead, the communication among hosts of different tenants
+# is forbidden.
+# In other words, hosts hs-t100-1 and hs-t100-2 are connected through the IPv6
+# L3 VPN of tenant 100 while hs-t200-3 and hs-t200-4 are connected using the
+# IPv6 L3 VPN of tenant 200. Cross connection between tenant 100 and tenant 200
+# is forbidden and thus, for example, hs-t100-1 cannot reach hs-t200-3 and vice
+# versa.
+#
+# Routers rt-1 and rt-2 implement IPv6 L3 VPN services leveraging the SRv6
+# architecture. The key components for such VPNs are: a) SRv6 Encap behavior,
+# b) SRv6 End.DT6 behavior and c) VRF.
+#
+# To explain how an IPv6 L3 VPN based on SRv6 works, let us briefly consider an
+# example where, within the same domain of tenant 100, the host hs-t100-1 pings
+# the host hs-t100-2.
+#
+# First of all, L2 reachability of the host hs-t100-2 is taken into account by
+# the router rt-1 which acts as a ndp proxy.
+#
+# When the host hs-t100-1 sends an IPv6 packet destined to hs-t100-2, the
+# router rt-1 receives the packet on the internal veth-t100 interface. Such
+# interface is enslaved to the VRF vrf-100 whose associated table contains the
+# SRv6 Encap route for encapsulating any IPv6 packet in a IPv6 plus the Segment
+# Routing Header (SRH) packet. This packet is sent through the (IPv6) core
+# network up to the router rt-2 that receives it on veth0 interface.
+#
+# The rt-2 router uses the 'localsid' routing table to process incoming
+# IPv6+SRH packets which belong to the VPN of the tenant 100. For each of these
+# packets, the SRv6 End.DT6 behavior removes the outer IPv6+SRH headers and
+# performs the lookup on the vrf-100 table using the destination address of
+# the decapsulated IPv6 packet. Afterwards, the packet is sent to the host
+# hs-t100-2 through the veth-t100 interface.
+#
+# The ping response follows the same processing but this time the role of rt-1
+# and rt-2 are swapped.
+#
+# Of course, the IPv6 L3 VPN for tenant 200 works exactly as the IPv6 L3 VPN
+# for tenant 100. In this case, only hosts hs-t200-3 and hs-t200-4 are able to
+# connect with each other.
