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

We've added 116 non-merge commits during the last 27 day(s) which contain
a total of 156 files changed, 5662 insertions(+), 1489 deletions(-).

The main changes are:

1) Adds support of pointers to types with known size among global function
args to overcome the limit on max # of allowed args, from Dmitrii Banshchikov.

2) Add bpf_iter for task_vma which can be used to generate information similar
to /proc/pid/maps, from Song Liu.

3) Enable bpf_{g,s}etsockopt() from all sock_addr related program hooks. Allow
rewriting bind user ports from BPF side below the ip_unprivileged_port_start
range, both from Stanislav Fomichev.

4) Prevent recursion on fentry/fexit & sleepable programs and allow map-in-map
as well as per-cpu maps for the latter, from Alexei Starovoitov.

5) Add selftest script to run BPF CI locally. Also enable BPF ringbuffer
for sleepable programs, both from KP Singh.

6) Extend verifier to enable variable offset read/write access to the BPF

hi,
resolve_btfids tool is used during the kernel build,
so we should clean it on kernel's make clean.

v2 changes:
- add Song's acks on patches 1 and 4 (others changed) [Song]
- add missing / [Andrii]
- change srctree variable initialization [Andrii]
- shifted ifdef for clean target [Andrii]

tools/resolve_btfids: Build libbpf and libsubcmd in separate directories

Setting up separate build directories for libbpf and libpsubcmd,
so it's separated from other objects and we don't get them mixed
in the future.

It also simplifies cleaning, which is now simple rm -rf.

Also there's no need for FEATURE-DUMP.libbpf and bpf_helper_defs.h
files in .gitignore anymore.
