Merge tag '5.17-net-next' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

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

- Defer freeing TCP skbs to the BH handler, whenever possible, or at
least perform the freeing outside of the socket lock section to
decrease cross-CPU allocator work and improve latency.

- Add netdevice refcount tracking to locate sources of netdevice and
net namespace refcount leaks.

- Make Tx watchdog less intrusive - avoid pausing Tx and restarting
all queues from a single CPU removing latency spikes.

- Various small optimizations throughout the stack from Eric Dumazet.

- Make netdev->dev_addr[] constant, force modifications to go via
appropriate helpers to allow us to keep addresses in ordered data
structures.

- Replace unix_table_lock with per-hash locks, improving performance
of bind() calls.

- Extend skb drop tracepoint with a drop reason.

- Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.

BPF
---

- New helpers:
- bpf_find_vma(), find and inspect VMAs for profiling use cases
- bpf_loop(), runtime-bounded loop helper trading some execution
time for much faster (if at all converging) verification
- bpf_strncmp(), improve performance, avoid compiler flakiness
- bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt()
for tracing programs, all inlined by the verifier

- Support BPF relocations (CO-RE) in the kernel loader.

- Further the support for BTF_TYPE_TAG annotations.

- Allow access to local storage in sleepable helpers.

- Convert verifier argument types to a composable form with different
attributes which can be shared across types (ro, maybe-null).

- Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
creating new, extensible ones where missing and deprecating those
to be removed.

Protocols
---------

- WiFi (mac80211/cfg80211):
- notify user space about long "come back in N" AP responses,
allow it to react to such temporary rejections
- allow non-standard VHT MCS 10/11 rates
- use coarse time in airtime fairness code to save CPU cycles

- Bluetooth:
- rework of HCI command execution serialization to use a common
queue and work struct, and improve handling errors reported in
the middle of a batch of commands
- rework HCI event handling to use skb_pull_data, avoiding packet
parsing pitfalls
- support AOSP Bluetooth Quality Report

- SMC:
- support net namespaces, following the RDMA model
- improve connection establishment latency by pre-clearing buffers
- introduce TCP ULP for automatic redirection to SMC

- Multi-Path TCP:
- support ioctls: SIOCINQ, OUTQ, and OUTQNSD
- support socket options: IP_TOS, IP_FREEBIND, IP_TRANSPARENT,
IPV6_FREEBIND, and IPV6_TRANSPARENT, TCP_CORK and TCP_NODELAY
- support cmsgs: TCP_INQ
- improvements in the data scheduler (assigning data to subflows)
- support fastclose option (quick shutdown of the full MPTCP
connection, similar to TCP RST in regular TCP)

- MCTP (Management Component Transport) over serial, as defined by
DMTF spec DSP0253 - "MCTP Serial Transport Binding".

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

- Support timestamping on bond interfaces in active/passive mode.

- Introduce generic phylink link mode validation for drivers which
don't have any quirks and where MAC capability bits fully express
what's supported. Allow PCS layer to participate in the validation.
Convert a number of drivers.

- Add support to set/get size of buffers on the Rx rings and size of
the tx copybreak buffer via ethtool.

- Support offloading TC actions as first-class citizens rather than
only as attributes of filters, improve sharing and device resource
utilization.

- WiFi (mac80211/cfg80211):
- support forwarding offload (ndo_fill_forward_path)
- support for background radar detection hardware
- SA Query Procedures offload on the AP side

New hardware / drivers
----------------------

- tsnep - FPGA based TSN endpoint Ethernet MAC used in PLCs with
real-time requirements for isochronous communication with protocols
like OPC UA Pub/Sub.

integrated into many older Qualcomm SoCs, e.g. MSM8916 or MSM8974
(qcom_bam_dmux).

- Microchip LAN966x multi-port Gigabit AVB/TSN Ethernet Switch driver
with support for bridging, VLANs and multicast forwarding
(lan966x).
