Merge tag 'net-next-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Not much excitement - a handful of large patchsets (devmem among them)
did not make it in time.

Core & protocols:

- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT

- Use flex array for netdevice priv area, ensure its cache alignment

- Add a sysctl knob to allow user to specify a default rto_min at
socket init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful

- Support scheduling transmission of packets based on CLOCK_TAI

- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned
off using cpusets

- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address

- Allow configuration of multipath hash seed, to both allow
synchronizing hashing of two routers, and preventing partial
accidental sync

- Improve TCP compliance with RFC 9293 for simultaneous connect()

- Support sending NAT keepalives in IPsec ESP in UDP states.
Userspace IKE daemon had to do this before, but the kernel can
better keep track of it

- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled

- Introduce IPPROTO_SMC for selecting SMC when socket is created

- Allow UDP GSO transmit from devices with no checksum offload

- openvswitch: add packet sampling via psample, separating the
sampled traffic from "upcall" packets sent to user space for
forwarding

- nf_tables: shrink memory consumption for transaction objects

Things we sprinkled into general kernel code:

- Power Sequencing subsystem (used by Qualcomm Bluetooth driver for
QCA6390) [ Already merged separately - Linus ]

- Add IRQ information in sysfs for auxiliary bus

- Introduce guard definition for local_lock

- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures

BPF:

- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered

- Add new kfuncs for a generic, open-coded bits iterator

- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head

- Support resilient split BTF which cuts down on duplication and
makes BTF as compact as possible WRT BTF from modules

- Add support for dumping kfunc prototypes from BTF which enables
both detecting as well as dumping compilable prototypes for kfuncs

- riscv64 BPF JIT improvements in particular to add 12-argument
support for BPF trampolines and to utilize bpf_prog_pack for the
latter

- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs

Driver API:

- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose

- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits

- Track additional RSS contexts in the core, make sure configuration
changes don't break them

- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated
ESP data paths

- Support updating firmware on SFP modules

Tests and tooling:

- mptcp: use net/lib.sh to manage netns

- TCP-AO and TCP-MD5: replace debug prints used by tests with
tracepoints

- openvswitch: make test self-contained (don't depend on OvS CLI
tools)

====================
idpf: XDP chapter I: convert Rx to libeth

Alexander Lobakin says:

XDP for idpf is currently 5 chapters:
* convert Rx to libeth (this);
* convert Tx and stats to libeth;
* generic XDP and XSk code changes, libeth_xdp;
* actual XDP for idpf via libeth_xdp;
* XSk for idpf (^).

Part I does the following:
* splits &idpf_queue into 4 (RQ, SQ, FQ, CQ) and puts them on a diet;
* ensures optimal cacheline placement, strictly asserts CL sizes;
* moves currently unused/dead singleq mode out of line;
* reuses libeth's Rx ptype definitions and helpers;
* uses libeth's Rx buffer management for both header and payload;
* eliminates memcpy()s and coherent DMA uses on hotpath, uses
napi_build_skb() instead of in-place short skb allocation.

Most idpf patches, except for the queue split, removes more lines
than adds.

Expect far better memory utilization and +5-8% on Rx depending on
the case (+17% on skb XDP_DROP :>).

* '200GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
idpf: use libeth Rx buffer management for payload buffer
idpf: convert header split mode to libeth + napi_build_skb()
libeth: support different types of buffers for Rx
idpf: remove legacy Page Pool Ethtool stats
idpf: reuse libeth's definitions of parsed ptype structures
idpf: compile singleq code only under default-n CONFIG_IDPF_SINGLEQ
idpf: merge singleq and splitq &net_device_ops
idpf: strictly assert cachelines of queue and queue vector structures
idpf: avoid bloating &idpf_q_vector with big %NR_CPUS
idpf: split &idpf_queue into 4 strictly-typed queue structures
idpf: stop using macros for accessing queue descriptors
libeth: add cacheline / struct layout assertion helpers
page_pool: use __cacheline_group_{begin, end}_aligned()
cache: add __cacheline_group_{begin, end}_aligned() (+ couple more)

idpf: compile singleq code only under default-n CONFIG_IDPF_SINGLEQ

Currently, all HW supporting idpf supports the singleq model, but none
of it advertises it by default, as splitq is supported and preferred
for multiple reasons. Still, this almost dead code often times adds
hotpath branches and redundant cacheline accesses.
While it can't currently be removed, add CONFIG_IDPF_SINGLEQ and build
the singleq code only when it's enabled manually. This corresponds to
-10 Kb of object code size and a good bunch of hotpath checks.
idpf_is_queue_model_split() works as a gate and compiles out to `true`
when the config option is disabled.

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.

Introduce Intel IDPF driver

Pavan Kumar Linga says:

This patch series introduces the Intel Infrastructure Data Path Function
(IDPF) driver. It is used for both physical and virtual functions. Except
for some of the device operations the rest of the functionality is the
same for both PF and VF. IDPF uses virtchnl version2 opcodes and
structures defined in the virtchnl2 header file which helps the driver
to learn the capabilities and register offsets from the device
Control Plane (CP) instead of assuming the default values.

The format of the series follows the driver init flow to interface open.
To start with, probe gets called and kicks off the driver initialization
by spawning the 'vc_event_task' work queue which in turn calls the
'hard reset' function. As part of that, the mailbox is initialized which
is used to send/receive the virtchnl messages to/from the CP. Once that is
done, 'core init' kicks in which requests all the required global resources
from the CP and spawns the 'init_task' work queue to create the vports.

Based on the capability information received, the driver creates the said
number of vports (one or many) where each vport is associated to a netdev.
Also, each vport has its own resources such as queues, vectors etc.
From there, rest of the netdev_ops and data path are added.

IDPF implements both single queue which is traditional queueing model
as well as split queue model. In split queue model, it uses separate queue
for both completion descriptors and buffers which helps to implement
out-of-order completions. It also helps to implement asymmetric queues,
for example multiple RX completion queues can be processed by a single
RX buffer queue and multiple TX buffer queues can be processed by a
single TX completion queue. In single queue model, same queue is used
for both descriptor completions as well as buffer completions. It also
supports features such as generic checksum offload, generic receive
offload (hardware GRO) etc.
---
v7:
Patch 2:
* removed pci_[disable|enable]_pcie_error_reporting as they are dropped
from the core
Patch 4, 9:
* used 'kasprintf' instead of 'snprintf' to avoid providing explicit
character string size which also fixes "-Wformat-truncation" warnings
Patch 14:
* used 'ethtool_sprintf' instead of 'snprintf' to avoid providing explicit
character string size which also fixes "-Wformat-truncation" warning
* add string format argument to the 'ethtool_sprintf' to avoid warning on
"-Wformat-security"

v6: https://lore.kernel.org/netdev/20230825235954.894050-1-pavan.kumar.linga@intel.com/
Note: 'Acked-by' was only added to patches 1, 2, 12 and not to the other
patches because of the changes in v6

Patch 3, 4, 5, 6, 7, 8, 9, 11, 13, 14, 15:
* renamed 'reset_lock' to 'vport_ctrl_lock' to reflect the lock usage
* to avoid defensive programming, used 'vport_ctrl_lock' for the user
callbacks that access the 'vport' to prevent the hardware reset thread
from releasing the 'vport', when the user callback is in progress
* added some variables to netdev private structure to avoid vport access
if possible from ethtool and ndo callbacks
* moved 'mac_filter_list_lock' and MAC related flags to vport_config
structure and refactored mac filter flow to handle asynchronous
ndo mac filter callbacks
* stop the queues before starting the reset flow to avoid TX hangs
* removed 'sw_mutex' and 'stop_mutex' as they are not needed anymore
* added missing clear bit in 'init_task' error path
* renamed labels appropriately
Patch 8:
* replaced page_pool_put_page with page_pool_put_full_page
* for the page pool max_len, used PAGE_SIZE
Patch 10, 11, 13:
* made use of the 'netif_txq_maybe_stop', '__netif_txq_completed_wake'
helper macros
Patch 13:
* removed IDPF_HR_RESET_IN_PROG flag check in idpf_tx_singleq_start
as it is defensive
Patch 14:
* removed max descriptor check as the core does that
* removed unnecessary error messages
* removed the stats that are common between the ones reported by ethtool
and ip link
* replaced snprintf with ethtool_sprintf
* added a comment to explain the reason for the max queue check
* as the netdev queues are set on alloc, there is no need to set
them again on reset unless there is a queue change, so move the
'idpf_set_real_num_queues' to 'idpf_initiate_soft_reset'
Patch 15:
* reworded the 'configure SRIOV' in the commit message

v5: https://lore.kernel.org/netdev/20230816004305.216136-1-anthony.l.nguyen@intel.com/
Most Patches:
* wrapped line limit to 80 chars to those which don't effect readability
Patch 12:
* in skb_add_rx_frag, offset 'headlen' w.r.t page_offset when adding a
frag to avoid adding the header again
Patch 14:
* added NULL check for 'rxq' when dereferencing it in page_pool_get_stats

* adjusted the destroy sequence of the workqueues as per the alloc
sequence
Patch 4, 5, 9, 15:
* scrub unnecessary flags in 'idpf_flags'
- IDPF_REMOVE_IN_PROG flag can take care of the cases where
IDPF_REL_RES_IN_PROG is used, removed the later one
- IDPF_REQ_[TX|RX]_SPLITQ are replaced with struct variables
- IDPF_CANCEL_[SERVICE|STATS]_TASK are redundant as the work queue
doesn't get rescheduled again after 'cancel_delayed_work_sync'
- IDPF_HR_CORE_RESET is removed as there is no set_bit for this flag
- IDPF_MB_INTR_TRIGGER is removed as it is not needed anymore with the
mailbox workqueue implementation

idpf: add ethtool callbacks

Initialize all the ethtool ops that are supported by the driver and
add the necessary support for the ethtool callbacks. Also add
asynchronous link notification virtchnl support where the device
Control Plane sends the link status and link speed as an
asynchronous event message. Driver report the link speed on
ethtool .idpf_get_link_ksettings query.

Introduce soft reset function which is used by some of the ethtool
callbacks such as .set_channels, .set_ringparam etc. to change the
existing queue configuration. It deletes the existing queues by sending
delete queues virtchnl message to the CP and calls the 'vport_stop' flow
which disables the queues, vport etc. New set of queues are requested to
the CP and reconfigure the queue context by calling the 'vport_open'
flow. Soft reset flow also adjusts the number of vectors associated to a
vport if .set_channels is called.
