Merge tag 'net-next-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core:

- Introduce and use a single page frag cache for allocating small skb
heads, clawing back the 10-20% performance regression in UDP flood
test from previous fixes.

- Run packets which already went thru HW coalescing thru SW GRO. This
significantly improves TCP segment coalescing and simplifies
deployments as different workloads benefit from HW or SW GRO.

- Shrink the size of the base zero-copy send structure.

- Move TCP init under a new slow / sleepable version of DO_ONCE().

BPF:

- Add BPF-specific, any-context-safe memory allocator.

- Add helpers/kfuncs for PKCS#7 signature verification from BPF
programs.

- Define a new map type and related helpers for user space -> kernel
communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF).

- Allow targeting BPF iterators to loop through resources of one
task/thread.

- Add ability to call selected destructive functions. Expose
crash_kexec() to allow BPF to trigger a kernel dump. Use
CAP_SYS_BOOT check on the loading process to judge permissions.

- Enable BPF to collect custom hierarchical cgroup stats efficiently
by integrating with the rstat framework.

- Support struct arguments for trampoline based programs. Only
structs with size <= 16B and x86 are supported.

- Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping
sockets (instead of just TCP and UDP sockets).

- Add a helper for accessing CLOCK_TAI for time sensitive network
related programs.

- Support accessing network tunnel metadata's flags.

- Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open.

- Add support for writing to Netfilter's nf_conn:mark.

Protocols:

- WiFi: more Extremely High Throughput (EHT) and Multi-Link Operation
(MLO) work (802.11be, WiFi 7).

- vsock: improve support for SO_RCVLOWAT.

- SMC: support SO_REUSEPORT.

- Netlink: define and document how to use netlink in a "modern" way.
Support reporting missing attributes via extended ACK.

- IPSec: support collect metadata mode for xfrm interfaces.

- TCPv6: send consistent autoflowlabel in SYN_RECV state and RST
packets.

- TCP: introduce optional per-netns connection hash table to allow
better isolation between namespaces (opt-in, at the cost of memory
and cache pressure).

- MPTCP: support TCP_FASTOPEN_CONNECT.

- Add NEXT-C-SID support in Segment Routing (SRv6) End behavior.

- Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets.

- Open vSwitch:
- Allow specifying ifindex of new interfaces.
- Allow conntrack and metering in non-initial user namespace.

- TLS: support the Korean ARIA-GCM crypto algorithm.

- Remove DECnet support.

Driver API:

- Allow selecting the conduit interface used by each port in DSA
switches, at runtime.

- Ethernet Power Sourcing Equipment and Power Device support.

- Add tc-taprio support for queueMaxSDU parameter, i.e. setting per
traffic class max frame size for time-based packet schedules.

- Support PHY rate matching - adapting between differing host-side
and link-side speeds.

- Introduce QUSGMII PHY mode and 1000BASE-KX interface mode.

- Validate OF (device tree) nodes for DSA shared ports; make
phylink-related properties mandatory on DSA and CPU ports.
Enforcing more uniformity should allow transitioning to phylink.

- Require that flash component name used during update matches one of
the components for which version is reported by info_get().

- Remove "weight" argument from driver-facing NAPI API as much as
possible. It's one of those magic knobs which seemed like a good
idea at the time but is too indirect to use in practice.

- Support offload of TLS connections with 256 bit keys.

Merge branch 'add-a-second-bind-table-hashed-by-port-and-address'

Joanne Koong says:

====================
Add a second bind table hashed by port and address

Currently, there is one bind hashtable (bhash) that hashes by port only.
This patchset adds a second bind table (bhash2) that hashes by port and
address.

The motivation for adding bhash2 is to expedite bind requests in situations
where the port has many sockets in its bhash table entry (eg a large number
of sockets bound to different addresses on the same port), which makes checking
bind conflicts costly especially given that we acquire the table entry spinlock
while doing so, which can cause softirq cpu lockups and can prevent new tcp
connections.

We ran into this problem at Meta where the traffic team binds a large number
of IPs to port 443 and the bind() call took a significant amount of time
which led to cpu softirq lockups, which caused packet drops and other failures
on the machine.

When experimentally testing this on a local server for ~24k sockets bound to
the port, the results seen were:

ipv4:
before - 0.002317 seconds
with bhash2 - 0.000020 seconds

ipv6:
before - 0.002431 seconds
with bhash2 - 0.000021 seconds

The additions to the initial bhash2 submission [0] are:
* Updating bhash2 in the cases where a socket's rcv saddr changes after it has
* been bound
* Adding locks for bhash2 hashbuckets

selftests/net: Add test for timing a bind request to a port with a populated bhash entry

This test populates the bhash table for a given port with
MAX_THREADS * MAX_CONNECTIONS sockets, and then times how long
a bind request on the port takes.

When populating the bhash table, we create the sockets and then bind
the sockets to the same address and port (SO_REUSEADDR and SO_REUSEPORT
are set). When timing how long a bind on the port takes, we bind on a
different address without SO_REUSEPORT set. We do not set SO_REUSEPORT
because we are interested in the case where the bind request does not
go through the tb->fastreuseport path, which is fragile (eg
tb->fastreuseport path does not work if binding with a different uid).

To run the script:
Usage: ./bind_bhash.sh [-6 | -4] [-p port] [-a address]
6: use ipv6
4: use ipv4
port: Port number
address: ip address

Without any arguments, ./bind_bhash.sh defaults to ipv6 using ip address
"2001:0db8:0:f101::1" on port 443.

On my local machine, I see:
ipv4:
before - 0.002317 seconds
with bhash2 - 0.000020 seconds

ipv6:
before - 0.002431 seconds
with bhash2 - 0.000021 seconds
