Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core:

- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.

- Introduce sysctl to set default RPS configuration for new netdevs.

- Define Netlink protocol specification format which can be used to
describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.

- Expose all net/core sysctls inside netns.

- Remove 4s sleep in netpoll if carrier is instantly detected on
boot.

- Add configurable limit of MDB entries per port, and port-vlan.

- Continue populating drop reasons throughout the stack.

- Retire a handful of legacy Qdiscs and classifiers.

Protocols:

- Support IPv4 big TCP (TSO frames larger than 64kB).

- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.

- Track and report in procfs number of MPTCP sockets used.

- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path
manager.

- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).

- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).

- ICMP: add per-rate limit counters.

- Add support for user scanning requests in ieee802154.

- Remove static WEP support.

- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.

- WiFi 7 EHT channel puncturing support (client & AP).

BPF:

- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.

- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.

- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to
better support decap on GRE tunnel devices not operating in collect
metadata.

- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.

- Remove the need for trace_printk_lock for bpf_trace_printk and
bpf_trace_vprintk helpers.

- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.

- Significantly reduce the search time for module symbols by
livepatch and BPF.

- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.

- Add support for BPF trampoline on s390x and riscv64.

- Add capability to export the XDP features supported by the NIC.

- Add __bpf_kfunc tag for marking kernel functions as kfuncs.

- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.

Netfilter:

- Remove the CLUSTERIP target. It has been marked as obsolete for
years, and we still have WARN splats wrt races of the out-of-band
/proc interface installed by this target.

- Add 'destroy' commands to nf_tables. They are identical to the
existing 'delete' commands, but do not return an error if the
referenced object (set, chain, rule...) did not exist.

Driver API:

- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.

- Separate C22 and C45 MDIO bus transactions more clearly.

- Introduce new DCB table to control DSCP rewrite on egress.

- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.

- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.

- Add support for controlling MACSec offload using netlink SET.

- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into
multiple files, drop some of the unnecessarily granular locks and
factor out common parts of netlink operation handling.

- Add TX frame aggregation parameters (for USB drivers).

- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.

- Allow offloading of UDP NEW connections via act_ct.

- Add support for per action HW stats in TC.

- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).

- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless
Extensions for Wi-Fi 7 devices at all. Everyone should switch to
using nl80211 interface instead.

- Improve the CAN bit timing configuration. Use extack to return
error messages directly to user space, update the SJW handling,
including the definition of a new default value that will benefit
CAN-FD controllers, by increasing their oscillator tolerance.

Merge branch 'samples/bpf: modernize BPF functionality test programs'

"Daniel T. Lee" says:

====================

Currently, there are many programs under samples/bpf to test the
various functionality of BPF that have been developed for a long time.
However, the kernel (BPF) has changed a lot compared to the 2016 when
some of these test programs were first introduced.

Therefore, some of these programs use the deprecated function of BPF,
and some programs no longer work normally due to changes in the API.

To list some of the kernel changes that this patch set is focusing on,
- legacy BPF map declaration syntax support had been dropped [1]
- bpf_trace_printk() always append newline at the end [2]
- deprecated styled BPF section header (bpf_load style) [3]
- urandom_read tracepoint is removed (used for testing overhead) [4]
- ping sends packet with SOCK_DGRAM instead of SOCK_RAW [5]*
- use "vmlinux.h" instead of including individual headers

In addition to this, this patchset tries to modernize the existing
testing scripts a bit. And for network-related testing programs,
a separate header file was created and applied. (To use the
Endianness conversion function from xdp_sample and bunch of constants)

[1]: https://github.com/libbpf/libbpf/issues/282
[2]: commit ac5a72ea5c89 ("bpf: Use dedicated bpf_trace_printk event instead of trace_printk()")
[3]: commit ceb5dea56543 ("samples: bpf: Remove bpf_load loader completely")
[4]: commit 14c174633f34 ("random: remove unused tracepoints")
[5]: https://lwn.net/Articles/422330/

*: This is quite old, but I'm not sure why the code was initially
developed to filter only SOCK_RAW.
