Mubashir Adnan Qureshi says:

====================
net: Add PLB functionality to TCP

This patch series adds PLB (Protective Load Balancing) to TCP and hooks
it up to DCTCP. PLB is disabled by default and can be enabled using
relevant sysctls and support from underlying CC.

PLB (Protective Load Balancing) is a host based mechanism for load
balancing across switch links. It leverages congestion signals(e.g. ECN)
from transport layer to randomly change the path of the connection
experiencing congestion. PLB changes the path of the connection by
changing the outgoing IPv6 flow label for IPv6 connections (implemented
in Linux by calling sk_rethink_txhash()). Because of this implementation
mechanism, PLB can currently only work for IPv6 traffic. For more
information, see the SIGCOMM 2022 paper:
https://doi.org/10.1145/3544216.3544226

tcp: add u32 counter in tcp_sock and an SNMP counter for PLB

A u32 counter is added to tcp_sock for counting the number of PLB
triggered rehashes for a TCP connection. An SNMP counter is also
added to count overall PLB triggered rehash events for a host. These
counters are hooked up to PLB implementation for DCTCP.

TCP_NLA_REHASH is added to SCM_TIMESTAMPING_OPT_STATS that reports
the rehash attempts triggered due to PLB or timeouts. This gives
a historical view of sustained congestion or timeouts experienced
by the TCP connection.

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.

- Ethernet:
- Microchip KSZ9896 6-port Gigabit Ethernet Switch
- Renesas Ethernet AVB (EtherAVB-IF) Gen4 SoCs

Merge branch 'tcp-introduce-optional-per-netns-ehash'

Kuniyuki Iwashima says:

====================
tcp: Introduce optional per-netns ehash.

The more sockets we have in the hash table, the longer we spend looking
up the socket. While running a number of small workloads on the same
host, they penalise each other and cause performance degradation.

The root cause might be a single workload that consumes much more
resources than the others. It often happens on a cloud service where
different workloads share the same computing resource.

On EC2 c5.24xlarge instance (196 GiB memory and 524288 (1Mi / 2) ehash
entries), after running iperf3 in different netns, creating 24Mi sockets
without data transfer in the root netns causes about 10% performance
regression for the iperf3's connection.

thash_entries sockets length Gbps
524288 1 1 50.7
24Mi 48 45.1

It is basically related to the length of the list of each hash bucket.
For testing purposes to see how performance drops along the length,
I set 131072 (1Mi / 8) to thash_entries, and here's the result.

thash_entries sockets length Gbps
131072 1 1 50.7
1Mi 8 49.9
2Mi 16 48.9
4Mi 32 47.3
8Mi 64 44.6
16Mi 128 40.6
24Mi 192 36.3
32Mi 256 32.5
40Mi 320 27.0
48Mi 384 25.0

To resolve the socket lookup degradation, we introduce an optional
per-netns hash table for TCP, but it's just ehash, and we still share
the global bhash, bhash2 and lhash2.

With a smaller ehash, we can look up non-listener sockets faster and
isolate such noisy neighbours. Also, we can reduce lock contention.

For details, please see the last patch.

patch 1 - 4: prep for per-netns ehash
patch 5: small optimisation for netns dismantle without TIME_WAIT sockets
patch 6: add per-netns ehash

Many thanks to Eric Dumazet for reviewing and advising.

tcp: Don't allocate tcp_death_row outside of struct netns_ipv4.

We will soon introduce an optional per-netns ehash and access hash
tables via net->ipv4.tcp_death_row->hashinfo instead of &tcp_hashinfo
in most places.

It could harm the fast path because dereferences of two fields in net
and tcp_death_row might incur two extra cache line misses. To save one
dereference, let's place tcp_death_row back in netns_ipv4 and fetch
hashinfo via net->ipv4.tcp_death_row"."hashinfo.

Note tcp_death_row was initially placed in netns_ipv4, and commit
fbb8295248e1 ("tcp: allocate tcp_death_row outside of struct netns_ipv4")
changed it to a pointer so that we can fire TIME_WAIT timers after freeing
net. However, we don't do so after commit 04c494e68a13 ("Revert "tcp/dccp:
get rid of inet_twsk_purge()""), so we need not define tcp_death_row as a
pointer.

Also, we move refcount_dec_and_test(&tw_refcount) from tcp_sk_exit() to
tcp_sk_exit_batch() as a debug check.
