Merge tag 'net-next-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core & protocols:

- Support HW queue leasing, allowing containers to be granted access
to HW queues for zero-copy operations and AF_XDP

- Number of code moves to help the compiler with inlining. Avoid
output arguments for returning drop reason where possible

- Rework drop handling within qdiscs to include more metadata about
the reason and dropping qdisc in the tracepoints

- Remove the rtnl_lock use from IP Multicast Routing

- Pack size information into the Rx Flow Steering table pointer
itself. This allows making the table itself a flat array of u32s,
thus making the table allocation size a power of two

- Report TCP delayed ack timer information via socket diag

- Add ip_local_port_step_width sysctl to allow distributing the
randomly selected ports more evenly throughout the allowed space

- Add support for per-route tunsrc in IPv6 segment routing

- Start work of switching sockopt handling to iov_iter

- Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid
buffer size drifting up

- Support MSG_EOR in MPTCP

- Add stp_mode attribute to the bridge driver for STP mode selection.
This addresses concerns about call_usermodehelper() usage

- Remove UDP-Lite support (as announced in 2023)

- Remove support for building IPv6 as a module. Remove the now
unnecessary function calling indirection

Cross-tree stuff:

- Move Michael MIC code from generic crypto into wireless, it's
considered insecure but some WiFi networks still need it

Netfilter:

- Switch nft_fib_ipv6 module to no longer need temporary dst_entry
object allocations by using fib6_lookup() + RCU.

Florian W reports this gets us ~13% higher packet rate

- Convert IPVS's global __ip_vs_mutex to per-net service_mutex and
switch the service tables to be per-net. Convert some code that
walks the service lists to use RCU instead of the service_mutex

- Add more opinionated input validation to lower security exposure

- Make IPVS hash tables to be per-netns and resizable

Wireless:

- Finished assoc frame encryption/EPPKE/802.1X-over-auth

- Radar detection improvements

- Add 6 GHz incumbent signal detection APIs

- Multi-link support for FILS, probe response templates and client
probing

- New APIs and mac80211 support for NAN (Neighbor Aware Networking,
aka Wi-Fi Aware) so less work must be in firmware

Driver API:

- Add numerical ID for devlink instances (to avoid having to create
fake bus/device pairs just to have an ID). Support shared devlink
instances which span multiple PFs

- Add standard counters for reporting pause storm events (implement
in mlx5 and fbnic)

- Add configuration API for completion writeback buffering (implement
in mana)

- Support driver-initiated change of RSS context sizes

- Support DPLL monitoring input frequency (implement in zl3073x)

- Support per-port resources in devlink (implement in mlx5)

Misc:

- Expand the YAML spec for Netfilter

Merge branch 'udp-retire-udp-lite'

Kuniyuki Iwashima says:

====================
udp: Retire UDP-Lite.

In 2023, syzbot found a null-ptr-deref bug triggered when UDP-Lite
attempted to charge an skb after the total memory usage for UDP-Lite
_and_ UDP exceeded a system-wide threshold, net.ipv4.udp_mem[1].

Since this threshold is shared with UDP, the bug would have been
easy to trigger if any real-world applications were using UDP-Lite;
however, only syzbot ever stumbled upon it.

The bug had persisted since 2016, suggesting that UDP-Lite had
remained unused for 7 years at that point.

The bug was fixed in commit ad42a35bdfc6 ("udplite: Fix NULL pointer
dereference in __sk_mem_raise_allocated()."), and we added another
commit be28c14ac8bb ("udplite: Print deprecation notice.") to
announce the deprecation plan.

Since then, no one has complained, so it is time to officially
retire UDP-Lite.

This series first removes IPv6 and IPv4 UDP-Lite sockets, then
gradually cleans up the remaining dead/unnecessary code within
the UDP stack.

By removing a bunch of conditionals for UDP-Lite from the fast
path, udp_rr with 20,000 flows sees a 10% increase in pps
(13.3 Mpps -> 14.7 Mpps) on an AMD EPYC 7B12 (Zen 2) 64-Core
Processor platform.

[ With FDO, the baseline is much higher and the delta was ~3%,
20.1 Mpps -> 20.7 Mpps ]

ipv6: Retire UDP-Lite.

As announced in commit be28c14ac8bb ("udplite: Print deprecation
notice."), it's time to deprecate UDP-Lite.

As a first step, let's drop support for IPv6 UDP-Lite sockets.

We will remove the remaining dead code gradually.

Along with the removal of udplite.c, most of the functions exposed
via udp_impl.h are made static.

The prototypes of udpv6_sendmsg() and udpv6_recvmsg() are moved
to udp.h, but only udpv6_recvmsg() has INDIRECT_CALLABLE_DECLARE()
because udpv6_sendmsg() is exported for rxrpc since commit ed472b0c8783
("rxrpc: Call udp_sendmsg() directly").

Also, udpv6_recvmsg() needs INDIRECT_CALLABLE_SCOPE for
CONFIG_MITIGATION_RETPOLINE=n.

Note that udplite.h is included temporarily for udplite_csum().

Merge tag 'net-next-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
"Core & protocols:

- A significant effort all around the stack to guide the compiler to
make the right choice when inlining code, to avoid unneeded calls
for small helper and stack canary overhead in the fast-path.

This generates better and faster code with very small or no text
size increases, as in many cases the call generated more code than
the actual inlined helper.

- Extend AccECN implementation so that is now functionally complete,
also allow the user-space enabling it on a per network namespace
basis.

- Add support for memory providers with large (above 4K) rx buffer.
Paired with hw-gro, larger rx buffer sizes reduce the number of
buffers traversing the stack, dincreasing single stream CPU usage
by up to ~30%.

- Do not add HBH header to Big TCP GSO packets. This simplifies the
RX path, the TX path and the NIC drivers, and is possible because
user-space taps can now interpret correctly such packets without
the HBH hint.

- Allow IPv6 routes to be configured with a gateway address that is
resolved out of a different interface than the one specified,
aligning IPv6 to IPv4 behavior.

- Multi-queue aware sch_cake. This makes it possible to scale the
rate shaper of sch_cake across multiple CPUs, while still enforcing
a single global rate on the interface.

- Add support for the nbcon (new buffer console) infrastructure to
netconsole, enabling lock-free, priority-based console operations
that are safer in crash scenarios.

- Improve the TCP ipv6 output path to cache the flow information,
saving cpu cycles, reducing cache line misses and stack use.

- Improve netfilter packet tracker to resolve clashes for most
protocols, avoiding unneeded drops on rare occasions.

- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.

- Reduce tcp socket size by one cache line.

- Notify neighbour changes atomically, avoiding inconsistencies
between the notification sequence and the actual states sequence.

- Add vsock namespace support, allowing complete isolation of vsocks
across different network namespaces.

- Improve xsk generic performances with cache-alignment-oriented
optimizations.

- Support netconsole automatic target recovery, allowing netconsole
to reestablish targets when underlying low-level interface comes
back online.

Driver API:

- Support for switching the working mode (automatic vs manual) of a
DPLL device via netlink.

- Introduce PHY ports representation to expose multiple front-facing
media ports over a single MAC.

- Introduce "rx-polarity" and "tx-polarity" device tree properties,
to generalize polarity inversion requirements for differential
signaling.

- Add helper to create, prepare and enable managed clocks.

Device drivers:

- Add Huawei hinic3 PF etherner driver.

- Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet
controller.

- Add ethernet driver for MaxLinear MxL862xx switches

- Remove parallel-port Ethernet driver.

- Convert existing driver timestamp configuration reporting to
hwtstamp_get and remove legacy ioctl().

- Convert existing drivers to .get_rx_ring_count(), simplifing the RX
ring count retrieval. Also remove the legacy fallback path.

Merge branch 'gro-inline-tcp6_gro_-receive-complete'

====================
gro: inline tcp6_gro_{receive,complete}

On some platforms, GRO stack is too deep and causes cpu stalls.

Decreasing call depths by one shows a 1.5 % gain on Zen2 cpus.
(32 RX queues, 100Gbit NIC, RFS enabled, tcp_rr with 128 threads and 10,000 flows)

We can go further by inlining ipv6_gro_{receive,complete}
and take care of IPv4 if there is interest.

Note: two temporary __always_inline will be replaced with
inline_for_performance when/if available.

Merge tag 'net-next-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core & protocols:

- Support usec resolution of TCP timestamps, enabled selectively by a
route attribute.

- Defer regular TCP ACK while processing socket backlog, try to send
a cumulative ACK at the end. Increase single TCP flow performance
on a 200Gbit NIC by 20% (100Gbit -> 120Gbit).

- The Fair Queuing (FQ) packet scheduler:
- add built-in 3 band prio / WRR scheduling
- support bypass if the qdisc is mostly idle (5% speed up for TCP RR)
- improve inactive flow reporting
- optimize the layout of structures for better cache locality

- Support TCP Authentication Option (RFC 5925, TCP-AO), a more modern
replacement for the old MD5 option.

- Add more retransmission timeout (RTO) related statistics to
TCP_INFO.

- Support sending fragmented skbs over vsock sockets.

- Make sure we send SIGPIPE for vsock sockets if socket was
shutdown().

- Add sysctl for ignoring lower limit on lifetime in Router
Advertisement PIO, based on an in-progress IETF draft.

- Add sysctl to control activation of TCP ping-pong mode.

- Add sysctl to make connection timeout in MPTCP configurable.

- Support rcvlowat and notsent_lowat on MPTCP sockets, to help apps
limit the number of wakeups.

- Support netlink GET for MDB (multicast forwarding), allowing user
space to request a single MDB entry instead of dumping the entire
table.

- Support selective FDB flushing in the VXLAN tunnel driver.

- Allow limiting learned FDB entries in bridges, prevent OOM attacks.

- Allow controlling via configfs netconsole targets which were
created via the kernel cmdline at boot, rather than via configfs at
runtime.

- Support multiple PTP timestamp event queue readers with different
filters.

- MCTP over I3C.

BPF:

- Add new veth-like netdevice where BPF program defines the logic of
the xmit routine. It can operate in L3 and L2 mode.

- Support exceptions - allow asserting conditions which should never
be true but are hard for the verifier to infer. With some extra
flexibility around handling of the exit / failure:

https://lwn.net/Articles/938435/

- Add support for local per-cpu kptr, allow allocating and storing
per-cpu objects in maps. Access to those objects operates on the
value for the current CPU.

This allows to deprecate local one-off implementations of per-CPU
storage like BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE maps.

- Extend cgroup BPF sockaddr hooks for UNIX sockets. The use case is
for systemd to re-implement the LogNamespace feature which allows
running multiple instances of systemd-journald to process the logs
of different services.

- Enable open-coded task_vma iteration, after maple tree conversion
made it hard to directly walk VMAs in tracing programs.

- Add open-coded task, css_task and css iterator support. One of the
use cases is customizable OOM victim selection via BPF.

- Allow source address selection with bpf_*_fib_lookup().

- Add ability to pin BPF timer to the current CPU.

- Prevent creation of infinite loops by combining tail calls and
fentry/fexit programs.

- Add missed stats for kprobes to retrieve the number of missed
kprobe executions and subsequent executions of BPF programs.

- Inherit system settings for CPU security mitigations.

- Add BPF v4 CPU instruction support for arm32 and s390x.

Changes to common code:

- overflow: add DEFINE_FLEX() for on-stack definition of structs with
flexible array members.

- Process doc update with more guidance for reviewers.

Driver API:

- Simplify locking in WiFi (cfg80211 and mac80211 layers), use wiphy
mutex in most places and remove a lot of smaller locks.

- Create a common DPLL configuration API. Allow configuring and
querying state of PLL circuits used for clock syntonization, in
network time distribution.

- Unify fragmented and full page allocation APIs in page pool code.
Let drivers be ignorant of PAGE_SIZE.

- Rework PHY state machine to avoid races with calls to phy_stop().

- Notify DSA drivers of MAC address changes on user ports, improve
correctness of offloads which depend on matching port MAC
addresses.

- Allow antenna control on injected WiFi frames.

- Reduce the number of variants of napi_schedule().

- Simplify error handling when composing devlink health messages.

Misc:

- A lot of KCSAN data race "fixes", from Eric.

- A lot of __counted_by() annotations, from Kees.

- A lot of strncpy -> strscpy and printf format fixes.

- Replace master/slave terminology with conduit/user in DSA drivers.

- Handful of KUnit tests for netdev and WiFi core.

- AppleTalk COPS.

- AppleTalk ipddp.

- TI AR7 CPMAC Ethernet driver.

This is version 16 of TCP-AO support. It addresses the build warning
in the middle of patch set, reported by kernel test robot.

There's one Sparse warning introduced by tcp_sigpool_start():
__cond_acquires() seems to currently being broken. I've described
the reasoning for it on v9 cover letter. Also, checkpatch.pl warnings
were addressed, but yet I've left the ones that are more personal
preferences (i.e. 80 columns limit). Please, ping me if you have
a strong feeling about one of them.

net/tcp: Introduce TCP_AO setsockopt()s

Add 3 setsockopt()s:

net/tcp: Introduce TCP_AO setsockopt()s

Add 3 setsockopt()s:
1. TCP_AO_ADD_KEY to add a new Master Key Tuple (MKT) on a socket
2. TCP_AO_DEL_KEY to delete present MKT from a socket
3. TCP_AO_INFO to change flags, Current_key/RNext_key on a TCP-AO sk

Userspace has to introduce keys on every socket it wants to use TCP-AO
option on, similarly to TCP_MD5SIG/TCP_MD5SIG_EXT.
RFC5925 prohibits definition of MKTs that would match the same peer,
so do sanity checks on the data provided by userspace. Be as
conservative as possible, including refusal of defining MKT on
an established connection with no AO, removing the key in-use and etc.

(1) and (2) are to be used by userspace key manager to add/remove keys.
(3) main purpose is to set RNext_key, which (as prescribed by RFC5925)
is the KeyID that will be requested in TCP-AO header from the peer to
sign their segments with.

At this moment the life of ao_info ends in tcp_v4_destroy_sock().
