Merge tag 'net-next-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking changes from Jakub Kicinski:
"WiFi 7 and sendpage changes are the biggest pieces of work for this
release. The latter will definitely require fixes but I think that we
got it to a reasonable point.

Core:

- Rework the sendpage & splice implementations

Instead of feeding data into sockets page by page extend sendmsg
handlers to support taking a reference on the data, controlled by a
new flag called MSG_SPLICE_PAGES

Rework the handling of unexpected-end-of-file to invoke an
additional callback instead of trying to predict what the right
combination of MORE/NOTLAST flags is

Remove the MSG_SENDPAGE_NOTLAST flag completely

- Implement SCM_PIDFD, a new type of CMSG type analogous to
SCM_CREDENTIALS, but it contains pidfd instead of plain pid

- Enable socket busy polling with CONFIG_RT

- Improve reliability and efficiency of reporting for ref_tracker

- Auto-generate a user space C library for various Netlink families

Protocols:

- Allow TCP to shrink the advertised window when necessary, prevent
sk_rcvbuf auto-tuning from growing the window all the way up to
tcp_rmem[2]

- Use per-VMA locking for "page-flipping" TCP receive zerocopy

- Prepare TCP for device-to-device data transfers, by making sure
that payloads are always attached to skbs as page frags

- Make the backoff time for the first N TCP SYN retransmissions
linear. Exponential backoff is unnecessarily conservative

- Create a new MPTCP getsockopt to retrieve all info
(MPTCP_FULL_INFO)

- Avoid waking up applications using TLS sockets until we have a full
record

- Allow using kernel memory for protocol ioctl callbacks, paving the
way to issuing ioctls over io_uring

- Add nolocalbypass option to VxLAN, forcing packets to be fully
encapsulated even if they are destined for a local IP address

- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
in-kernel ECMP implementation (e.g. Open vSwitch) select the same
link for all packets. Support L4 symmetric hashing in Open vSwitch

- PPPoE: make number of hash bits configurable

- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
(ipconfig)

- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge)

- Support matching on Connectivity Fault Management (CFM) packets

- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug

- HSR: don't enable promiscuous mode if device offloads the proto

- Support active scanning in IEEE 802.15.4

- Continue work on Multi-Link Operation for WiFi 7

BPF:

- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used, or
in fact passing the verifier at all for complex programs,
especially those using open-coded iterators

- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what the
output buffer *should* be, without writing anything

- Accept dynptr memory as memory arguments passed to helpers

- Add routing table ID to bpf_fib_lookup BPF helper

- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands

- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only)

- Show target_{obj,btf}_id in tracing link fdinfo

- Addition of several new kfuncs (most of the names are
self-explanatory):
- Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
and bpf_dynptr_clone().
- bpf_task_under_cgroup()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs

Netfilter:

- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value

- Increase ip_vs_conn_tab_bits range for 64BIT builds

- Allow updating size of a set

- Improve NAT tuple selection when connection is closing

Driver API:

- Integrate netdev with LED subsystem, to allow configuring HW
"offloaded" blinking of LEDs based on link state and activity
(i.e. packets coming in and out)

- Support configuring rate selection pins of SFP modules

- Factor Clause 73 auto-negotiation code out of the drivers, provide
common helper routines

- Add more fool-proof helpers for managing lifetime of MDIO devices
associated with the PCS layer

- Allow drivers to report advanced statistics related to Time Aware
scheduler offload (taprio)

- Allow opting out of VF statistics in link dump, to allow more VFs
to fit into the message

- Split devlink instance and devlink port operations

main.c:73:10: fatal error: linux/rbtree.h: No such file or directory

| ^~~~~~~~~~~~~~~~

The reason is that tools/bpf/resolve_btfids/Makefile passes header
include paths by extending HOSTCFLAGS which is overridden by setting
HOSTCFLAGS in the make command (because of Makefile rules [1]).

This patch fixes the above problem by passing the include paths via
`HOSTCFLAGS_resolve_btfids` which is used by tools/build/Build.include
and can be combined with overridding HOSTCFLAGS.

Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core:

- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.

- Introduce sysctl to set default RPS configuration for new netdevs.

- Define Netlink protocol specification format which can be used to
describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.

- Expose all net/core sysctls inside netns.

- Remove 4s sleep in netpoll if carrier is instantly detected on
boot.

- Add configurable limit of MDB entries per port, and port-vlan.

- Continue populating drop reasons throughout the stack.

- Retire a handful of legacy Qdiscs and classifiers.

Protocols:

- Support IPv4 big TCP (TSO frames larger than 64kB).

- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.

- Track and report in procfs number of MPTCP sockets used.

- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path
manager.

- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).

- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).

- ICMP: add per-rate limit counters.

- Add support for user scanning requests in ieee802154.

- Remove static WEP support.

- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.

- WiFi 7 EHT channel puncturing support (client & AP).

BPF:

- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.

- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.

- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to
better support decap on GRE tunnel devices not operating in collect
metadata.

- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.

- Remove the need for trace_printk_lock for bpf_trace_printk and
bpf_trace_vprintk helpers.

- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.

- Significantly reduce the search time for module symbols by
livepatch and BPF.

- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.

- Add support for BPF trampoline on s390x and riscv64.

- Add capability to export the XDP features supported by the NIC.

- Add __bpf_kfunc tag for marking kernel functions as kfuncs.

- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.

Netfilter:

- Remove the CLUSTERIP target. It has been marked as obsolete for
years, and we still have WARN splats wrt races of the out-of-band
/proc interface installed by this target.

- Add 'destroy' commands to nf_tables. They are identical to the
existing 'delete' commands, but do not return an error if the
referenced object (set, chain, rule...) did not exist.

Driver API:

- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.

- Separate C22 and C45 MDIO bus transactions more clearly.

- Introduce new DCB table to control DSCP rewrite on egress.

- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.

- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.

- Add support for controlling MACSec offload using netlink SET.

- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into
multiple files, drop some of the unnecessarily granular locks and
factor out common parts of netlink operation handling.

- Add TX frame aggregation parameters (for USB drivers).

- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.

- Allow offloading of UDP NEW connections via act_ct.

- Add support for per action HW stats in TC.

- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).

- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless
Extensions for Wi-Fi 7 devices at all. Everyone should switch to
using nl80211 interface instead.

- Improve the CAN bit timing configuration. Use extack to return
error messages directly to user space, update the SJW handling,
including the definition of a new default value that will benefit
CAN-FD controllers, by increasing their oscillator tolerance.

There is a minor conflict in drivers/net/ethernet/intel/ice/ice_main.c
between commit 5b246e533d01 ("ice: split probe into smaller functions")
from the net-next tree and commit 66c0e13ad236 ("drivers: net: turn on
XDP features") from the bpf-next tree. Remove the hunk given ice_cfg_netdev()
is otherwise there a 2nd time, and add XDP features to the existing
ice_cfg_netdev() one:

[...]
ice_set_netdev_features(netdev);
netdev->xdp_features = NETDEV_XDP_ACT_BASIC | NETDEV_XDP_ACT_REDIRECT |
NETDEV_XDP_ACT_XSK_ZEROCOPY;
ice_set_ops(netdev);
[...]

tools/resolve_btfids: Pass HOSTCFLAGS as EXTRA_CFLAGS to prepare targets

Thorsten reported build issue with command line that defined extra
HOSTCFLAGS that were not passed into 'prepare' targets, but were
used to build resolve_btfids objects.

This results in build fail when these objects are linked together:

/usr/bin/ld: /build.../tools/bpf/resolve_btfids//libbpf/libbpf.a(libbpf-in.o):
relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE \
object; recompile with -fPIE

Fixing this by passing HOSTCFLAGS in EXTRA_CFLAGS as part of
HOST_OVERRIDES variable for prepare targets.

tools/resolve_btfids: Alter how HOSTCC is forced

HOSTCC is always wanted when building. Setting CC to HOSTCC happens
after tools/scripts/Makefile.include is included, meaning flags are
set assuming say CC is gcc, but then it can be later set to HOSTCC
which may be clang. tools/scripts/Makefile.include is needed for host
set up and common macros in objtool's Makefile. Rather than override
CC to HOSTCC, just pass CC as HOSTCC to Makefile.build, the libsubcmd
builds and the linkage step. This means the Makefiles don't see things
like CC changing and tool flag determination, and similar, work
properly.

Also, clear the passed subdir as otherwise an outer build may break by
inadvertently passing an inappropriate value.
