Merge tag 'net-next-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core
----

- Support TCPv6 segmentation offload with super-segments larger than
64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).

- Generalize skb freeing deferral to per-cpu lists, instead of
per-socket lists.

- Add a netdev statistic for packets dropped due to L2 address
mismatch (rx_otherhost_dropped).

- Continue work annotating skb drop reasons.

- Accept alternative netdev names (ALT_IFNAME) in more netlink
requests.

- Add VLAN support for AF_PACKET SOCK_RAW GSO.

- Allow receiving skb mark from the socket as a cmsg.

- Enable memcg accounting for veth queues, sysctl tables and IPv6.

BPF
---

- Add libbpf support for User Statically-Defined Tracing (USDTs).

- Speed up symbol resolution for kprobes multi-link attachments.

- Support storing typed pointers to referenced and unreferenced
objects in BPF maps.

- Add support for BPF link iterator.

- Introduce access to remote CPU map elements in BPF per-cpu map.

- Allow middle-of-the-road settings for the
kernel.unprivileged_bpf_disabled sysctl.

- Implement basic types of dynamic pointers e.g. to allow for
dynamically sized ringbuf reservations without extra memory copies.

Protocols
---------

- Retire port only listening_hash table, add a second bind table
hashed by port and address. Avoid linear list walk when binding to
very popular ports (e.g. 443).

- Add bridge FDB bulk flush filtering support allowing user space to
remove all FDB entries matching a condition.

- Introduce accept_unsolicited_na sysctl for IPv6 to implement
router-side changes for RFC9131.

- Support for MPTCP path manager in user space.

- Add MPTCP support for fallback to regular TCP for connections that
have never connected additional subflows or transmitted
out-of-sequence data (partial support for RFC8684 fallback).

- Avoid races in MPTCP-level window tracking, stabilize and improve
throughput.

- Support lockless operation of GRE tunnels with seq numbers enabled.

- WiFi support for host based BSS color collision detection.

- Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.

- Support transmission w/o flow control in CAN ISOTP (ISO 15765-2).

- Support zero-copy Tx with TLS 1.2 crypto offload (sendfile).

- Allow matching on the number of VLAN tags via tc-flower.

- Add tracepoint for tcp_set_ca_state().

Driver API
----------

- Improve error reporting from classifier and action offload.

- Add support for listing line cards in switches (devlink).

- Add helpers for reporting page pool statistics with ethtool -S.

- Add support for reading clock cycles when using PTP virtual clocks,
instead of having the driver convert to time before reporting. This
makes it possible to report time from different vclocks.

- Support configuring low-latency Tx descriptor push via ethtool.

- Separate Clause 22 and Clause 45 MDIO accesses more explicitly.

xsk: Drop ternary operator from xskq_cons_has_entries

Simplify the mentioned helper function by removing ternary operator. The
expression that is there outputs the boolean value by itself.

This helper might be used in the hot path so this simplification can
also be considered as micro optimization.

xsk: Improve xdp_do_redirect() error codes

The error codes returned by xdp_do_redirect() when redirecting a frame
to an AF_XDP socket has not been very useful. A driver could not
distinguish between different errors. Prior this change the following
codes where used:

Socket not bound or incorrect queue/netdev: EINVAL
XDP frame/AF_XDP buffer size mismatch: ENOSPC
Could not allocate buffer (copy mode): ENOSPC
AF_XDP Rx buffer full: ENOSPC

After this change:

Socket not bound or incorrect queue/netdev: EINVAL
XDP frame/AF_XDP buffer size mismatch: ENOSPC
Could not allocate buffer (copy mode): ENOMEM
AF_XDP Rx buffer full: ENOBUFS

An AF_XDP zero-copy driver can now potentially determine if the
failure was due to a full Rx buffer, and if so stop processing more
frames, yielding to the userland AF_XDP application.

Merge tag 'net-next-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

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

Merge branch 'xsk-batching'

Maciej Fijalkowski says:

====================
Unfortunately, similar scalability issues that were addressed for XDP
processing in ice, exist for XDP in the zero-copy driver used by AF_XDP.
Let's resolve them in mostly the same way as we did in [0] and utilize
the Tx batching API from XSK buffer pool.

Move the array of Tx descriptors that is used with batching approach to
the XSK buffer pool. This means that future users of this API will not
have to carry the array on their own side, they can simple refer to
pool's tx_desc array.

We also improve the Rx side where we extend ice_alloc_rx_buf_zc() to
handle the ring wrap and bump Rx tail more frequently. By doing so,
Rx side is adjusted to Tx and it was needed for l2fwd scenario.

Here are the improvements of performance numbers that this set brings
measured with xdpsock app in busy poll mode for 1 and 2 core modes.
Both Tx and Rx rings were sized to 1k length and busy poll budget was
256.

----------------------------------------------------------------
| txonly: | l2fwd | rxdrop
----------------------------------------------------------------
1C | 149% | 14% | 3%
----------------------------------------------------------------
2C | 134% | 20% | 5%
----------------------------------------------------------------

Next step will be to introduce batching onto Rx side.

v5:
* collect acks
* fix typos
* correct comments showing cache line boundaries in ice_tx_ring struct
v4 - address Alexandr's review:
* new patch (2) for making sure ring size is pow(2) when attaching
xsk socket
* don't open code ALIGN_DOWN (patch 3)
* resign from storing tx_thresh in ice_tx_ring (patch 4)
* scope variables in a better way for Tx batching (patch 7)
v3:
* drop likely() that was wrapping napi_complete_done (patch 1)
* introduce configurable Tx threshold (patch 2)
* handle ring wrap on Rx side when allocating buffers (patch 3)
* respect NAPI budget when cleaning Tx descriptors in ZC (patch 6)
v2:
* introduce new patch that resets @next_dd and @next_rs fields
* use batching API for AF_XDP Tx on ice side

i40e: xsk: Move tmp desc array from driver to pool

Move desc_array from the driver to the pool. The reason behind this is
that we can then reuse this array as a temporary storage for descriptors
in all zero-copy drivers that use the batched interface. This will make
it easier to add batching to more drivers.

i40e is the only driver that has a batched Tx zero-copy
implementation, so no need to touch any other driver.
