Merge tag 'net-next-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
"Core:

- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
default value allows for better BIG TCP performances

- Reduce compound page head access for zero-copy data transfers

- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when
possible

- Threaded NAPI improvements, adding defer skb free support and
unneeded softirq avoidance

- Address dst_entry reference count scalability issues, via false
sharing avoidance and optimize refcount tracking

- Add lockless accesses annotation to sk_err[_soft]

- Optimize again the skb struct layout

- Extends the skb drop reasons to make it usable by multiple
subsystems

- Better const qualifier awareness for socket casts

BPF:

- Add skb and XDP typed dynptrs which allow BPF programs for more
ergonomic and less brittle iteration through data and
variable-sized accesses

- Add a new BPF netfilter program type and minimal support to hook
BPF programs to netfilter hooks such as prerouting or forward

- Add more precise memory usage reporting for all BPF map types

- Adds support for using {FOU,GUE} encap with an ipip device
operating in collect_md mode and add a set of BPF kfuncs for
controlling encap params

- Allow BPF programs to detect at load time whether a particular
kfunc exists or not, and also add support for this in light
skeleton

- Bigger batch of BPF verifier improvements to prepare for upcoming
BPF open-coded iterators allowing for less restrictive looping
capabilities

- Rework RCU enforcement in the verifier, add kptr_rcu and enforce
BPF programs to NULL-check before passing such pointers into kfunc

- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and
in local storage maps

- Enable RCU semantics for task BPF kptrs and allow referenced kptr
tasks to be stored in BPF maps

- Add support for refcounted local kptrs to the verifier for allowing
shared ownership, useful for adding a node to both the BPF list and
rbtree

- Add BPF verifier support for ST instructions in
convert_ctx_access() which will help new -mcpu=v4 clang flag to
start emitting them

- Add ARM32 USDT support to libbpf

- Improve bpftool's visual program dump which produces the control
flow graph in a DOT format by adding C source inline annotations

Protocols:

- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
indicates the provenance of the IP address

- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition

- Add the handshake upcall mechanism, allowing the user-space to
implement generic TLS handshake on kernel's behalf

- Bridge: support per-{Port, VLAN} neighbor suppression, increasing
resilience to nodes failures

- SCTP: add support for Fair Capacity and Weighted Fair Queueing
schedulers

- MPTCP: delay first subflow allocation up to its first usage. This
will allow for later better LSM interaction

- xfrm: Remove inner/outer modes from input/output path. These are
not needed anymore

- WiFi:
- reduced neighbor report (RNR) handling for AP mode
- HW timestamping support
- support for randomized auth/deauth TA for PASN privacy
- per-link debugfs for multi-link
- TC offload support for mac80211 drivers
- mac80211 mesh fast-xmit and fast-rx support
- enable Wi-Fi 7 (EHT) mesh support

Netfilter:

- Add nf_tables 'brouting' support, to force a packet to be routed
instead of being bridged

- Update bridge netfilter and ovs conntrack helpers to handle IPv6
Jumbo packets properly, i.e. fetch the packet length from
hop-by-hop extension header. This is needed for BIT TCP support

- The iptables 32bit compat interface isn't compiled in by default
anymore

- Move ip(6)tables builtin icmp matches to the udptcp one. This has
the advantage that icmp/icmpv6 match doesn't load the
iptables/ip6tables modules anymore when iptables-nft is used

- Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device

Driver API:

- Remove redundant Device Control Error Reporting Enable, as PCI core
has already error reporting enabled at enumeration time

- Move Multicast DB netlink handlers to core, allowing devices other
then bridge to use them

- Allow the page_pool to directly recycle the pages from safely
localized NAPI

- Implement lockless TX queue stop/wake combo macros, allowing for
further code de-duplication and sanitization

- Add YNL support for user headers and struct attrs

- Add partial YNL specification for devlink

- Add partial YNL specification for ethtool

- Add tc-mqprio and tc-taprio support for preemptible traffic classes

- Add tx push buf len param to ethtool, specifies the maximum number
of bytes of a transmitted packet a driver can push directly to the
underlying device

- Add basic LED support for switch/phy

- Add NAPI documentation, stop relaying on external links

- Convert dsa_master_ioctl() to netdev notifier. This is a
preparatory work to make the hardware timestamping layer selectable
by user space

- Add transceiver support and improve the error messages for CAN-FD
controllers

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.
