Merge tag 'net-next-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

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

- Large effort by Eric to lower rtnl_lock pressure and remove locks:

- Make commonly used parts of rtnetlink (address, route dumps
etc) lockless, protected by RCU instead of rtnl_lock.

- Add a netns exit callback which already holds rtnl_lock,
allowing netns exit to take rtnl_lock once in the core instead
of once for each driver / callback.

- Remove locks / serialization in the socket diag interface.

- Remove 6 calls to synchronize_rcu() while holding rtnl_lock.

- Remove the dev_base_lock, depend on RCU where necessary.

- Support busy polling on a per-epoll context basis. Poll length and
budget parameters can be set independently of system defaults.

- Introduce struct net_hotdata, to make sure read-mostly global
config variables fit in as few cache lines as possible.

- Add optional per-nexthop statistics to ease monitoring / debug of
ECMP imbalance problems.

- Support TCP_NOTSENT_LOWAT in MPTCP.

- Ensure that IPv6 temporary addresses' preferred lifetimes are long
enough, compared to other configured lifetimes, and at least 2 sec.

- Support forwarding of ICMP Error messages in IPSec, per RFC 4301.

- Add support for the independent control state machine for bonding
per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
control state machine.

- Add "network ID" to MCTP socket APIs to support hosts with multiple
disjoint MCTP networks.

- Re-use the mono_delivery_time skbuff bit for packets which user
space wants to be sent at a specified time. Maintain the timing
information while traversing veth links, bridge etc.

- Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.

- Simplify many places iterating over netdevs by using an xarray
instead of a hash table walk (hash table remains in place, for use
on fastpaths).

- Speed up scanning for expired routes by keeping a dedicated list.

- Speed up "generic" XDP by trying harder to avoid large allocations.

- Support attaching arbitrary metadata to netconsole messages.

Things we sprinkled into general kernel code:

- Enforce VM_IOREMAP flag and range in ioremap_page_range and
introduce VM_SPARSE kind and vm_area_[un]map_pages (used by
bpf_arena).

- Rework selftest harness to enable the use of the full range of ksft
exit code (pass, fail, skip, xfail, xpass).

Netfilter:

- Allow userspace to define a table that is exclusively owned by a
daemon (via netlink socket aliveness) without auto-removing this
table when the userspace program exits. Such table gets marked as
orphaned and a restarting management daemon can re-attach/regain
ownership.

- Speed up element insertions to nftables' concatenated-ranges set
type. Compact a few related data structures.

BPF:

- Add BPF token support for delegating a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application.

- Introduce bpf_arena which is sparse shared memory region between
BPF program and user space where structures inside the arena can
have pointers to other areas of the arena, and pointers work
seamlessly for both user-space programs and BPF programs.

- Introduce may_goto instruction that is a contract between the
verifier and the program. The verifier allows the program to loop
assuming it's behaving well, but reserves the right to terminate
it.

- Extend the BPF verifier to enable static subprog calls in spin lock
critical sections.

- Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops
type.

- Add support for retrieval of cookies for perf/kprobe multi links.

- Support arbitrary TCP SYN cookie generation / validation in the TC
layer with BPF to allow creating SYN flood handling in BPF
firewalls.

- Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF
objects.

Wireless:

- Add SPP (signaling and payload protected) AMSDU support.

- Support wider bandwidth OFDMA, as required for EHT operation.

Driver API:

- Major overhaul of the Energy Efficient Ethernet internals to
support new link modes (2.5GE, 5GE), share more code between
drivers (especially those using phylib), and encourage more
uniform behavior. Convert and clean up drivers.

- Define an API for querying per netdev queue statistics from
drivers.

- IPSec: account in global stats for fully offloaded sessions.

- Create a concept of Ethernet PHY Packages at the Device Tree level,
to allow parameterizing the existing PHY package code.

- Enable Rx hashing (RSS) on GTP protocol fields.

Misc:

- Improvements and refactoring all over networking selftests.

- Create uniform module aliases for TC classifiers, actions, and
packet schedulers to simplify creating modprobe policies.

- Address all missing MODULE_DESCRIPTION() warnings in networking.

- Extend the Netlink descriptions in YAML to cover message
encapsulation or "Netlink polymorphism", where interpretation of
nested attributes depends on link type, classifier type or some
other "class type".

Merge tag 'net-next-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
"The most interesting thing is probably the networking structs
reorganization and a significant amount of changes is around
self-tests.

Core & protocols:

- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up build
time warnings to safeguard against future header changes

This improves TCP performances with many concurrent connections up
to 40%

- Add page-pool netlink-based introspection, exposing the memory
usage and recycling stats. This helps indentify bad PP users and
possible leaks

- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set. This
lowers the time taken by connect() for hosts having many active
connections to the same destination

- Refactor the TCP bind conflict code, shrinking related socket
structs

- Refactor TCP SYN-Cookie handling, as a preparation step to allow
arbitrary SYN-Cookie processing via eBPF

- Tune optmem_max for 0-copy usage, increasing the default value to
128KB and namespecifying it

- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations

- Reduce extension header parsing overhead at GRO time

- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries

- Reorder nftables struct members, to keep data accessed by the
datapath first

- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer

- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex)

- More data-race annotations

- Extend the diag interface to dump TCP bound-only sockets

- Conditional notification of events for TC qdisc class and actions

- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID

- Implement SMCv2.1 virtual ISM device support

- Add support for Batman-avd mulicast packet type

BPF:

- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers.
This improves the verifier "instructions processed" metric from
single digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer
experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes

- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload

- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y

- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques

- Support uid/gid options when mounting bpffs

- Add a new kfunc which acquires the associated cgroup of a task
within a specific cgroup v1 hierarchy where the latter is
identified by its id

- Extend verifier to allow bpf_refcount_acquire() of a map value
field obtained via direct load which is a use-case needed in
sched_ext

- Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter

- Support for VLAN tag in XDP hints

- Remove deprecated bpfilter kernel leftovers given the project is
developed in user-space (https://github.com/facebook/bpfilter)

Misc:

- Support for parellel TC self-tests execution

- Increase MPTCP self-tests coverage

- Updated the bridge documentation, including several so-far
undocumented features

- Convert all the net self-tests to run in unique netns, to avoid
random failures due to conflict and allow concurrent runs

- Add TCP-AO self-tests

- Add kunit tests for both cfg80211 and mac80211

- Autogenerate Netlink families documentation from YAML spec

- Add yml-gen support for fixed headers and recursive nests, the tool
can now generate user-space code for all genetlink families for
which we have specs

- A bunch of additional module descriptions fixes

- Catch incorrect freeing of pages belonging to a page pool

Driver API:

- Rust abstractions for network PHY drivers; do not cover yet the
full C API, but already allow implementing functional PHY drivers
in rust

- Introduce queue and NAPI support in the netdev Netlink interface,
allowing complete access to the device <> NAPIs <> queues
relationship

- Introduce notifications filtering for devlink to allow control
application scale to thousands of instances

- Improve PHY validation, requesting rate matching information for
each ethtool link mode supported by both the PHY and host

- Add support for ethtool symmetric-xor RSS hash

- ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
platform

- Expose pin fractional frequency offset value over new DPLL generic
netlink attribute

- Convert older drivers to platform remove callback returning void

- Add support for PHY package MMD read/write

New hardware / drivers:

- Ethernet:
- Octeon CN10K devices
- Broadcom 5760X P7
- Qualcomm SM8550 SoC
- Texas Instrument DP83TG720S PHY

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.

Merge branch 'dpll-api'

Vadim Fedorenko says:

====================
Create common DPLL configuration API

Implement common API for DPLL configuration and status reporting.
The API utilises netlink interface as transport for commands and event
notifications. This API aims to extend current pin configuration
provided by PTP subsystem and make it flexible and easy to cover
complex configurations.

Netlink interface is based on ynl spec, it allows use of in-kernel
tools/net/ynl/cli.py application to control the interface with properly
formated command and json attribute strings. Here are few command
examples of how it works with `ice` driver on supported NIC:

- dump dpll devices:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--dump device-get
[{'clock-id': 4658613174691613800,
'id': 0,
'lock-status': 'locked-ho-acq',
'mode': 'automatic',
'mode-supported': ['automatic'],
'module-name': 'ice',
'type': 'eec'},
{'clock-id': 4658613174691613800,
'id': 1,
'lock-status': 'locked-ho-acq',
'mode': 'automatic',
'mode-supported': ['automatic'],
'module-name': 'ice',
'type': 'pps'}]

- get single pin info:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--do pin-get --json '{"id":2}'
{'board-label': 'C827_0-RCLKA',
'clock-id': 4658613174691613800,
'capabilities': 6,
'frequency': 1953125,
'id': 2,
'module-name': 'ice',
'parent-device': [{'direction': 'input',
'parent-id': 0,
'prio': 9,
'state': 'disconnected'},
{'direction': 'input',
'parent-id': 1,
'prio': 9,
'state': 'disconnected'}],
'type': 'mux'}

- set pin's state on dpll:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--do pin-set --json '{"id":2, "parent-device":{"parent-id":1, "state":2}}'

- set pin's prio on dpll:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--do pin-set --json '{"id":2, "parent-device":{"parent-id":1, "prio":4}}'

- set pin's state on parent pin:
$ sudo ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml \
--do pin-set --json '{"id":13, "parent-pin":{"parent-id":2, "state":1}}'

Merge branch '200GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue

Tony Nguyen says:

====================
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

v4: https://lore.kernel.org/netdev/20230808003416.3805142-1-anthony.l.nguyen@intel.com/

Patch 2 to 15:
* add kernel-doc for idpf.h and idpf_txrx.h enums and structures
Patch 4, 5, 15:
* 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

negative and updated in all the places whereever applicable
Patch 6:
* changed the commit message to "add ptypes and MAC filter support"
