Merge tag 'net-next-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

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

- Complete rework of garbage collection of AF_UNIX sockets.

AF_UNIX is prone to forming reference count cycles due to fd
passing functionality. New method based on Tarjan's Strongly
Connected Components algorithm should be both faster and remove a
lot of workarounds we accumulated over the years.

- Add TCP fraglist GRO support, allowing chaining multiple TCP
packets and forwarding them together. Useful for small switches /
routers which lack basic checksum offload in some scenarios (e.g.
PPPoE).

- Support using SMP threads for handling packet backlog i.e. packet
processing from software interfaces and old drivers which don't use
NAPI. This helps move the processing out of the softirq jumble.

- Continue work of converting from rtnl lock to RCU protection.

Don't require rtnl lock when reading: IPv6 routing FIB, IPv6
address labels, netdev threaded NAPI sysfs files, bonding driver's
sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics,
TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot
of the link information available via rtnetlink.

- Small optimizations from Eric to UDP wake up handling, memory
accounting, RPS/RFS implementation, TCP packet sizing etc.

- Allow direct page recycling in the bulk API used by XDP, for +2%
PPS.

- Support peek with an offset on TCP sockets.

- Add MPTCP APIs for querying last time packets were received/sent/acked
and whether MPTCP "upgrade" succeeded on a TCP socket.

- Add intra-node communication shortcut to improve SMC performance.

- Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol
driver.

- Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver.

- Add reset reasons for tracing what caused a TCP reset to be sent.

- Introduce direction attribute for xfrm (IPSec) states. State can be
used either for input or output packet processing.

Things we sprinkled into general kernel code:

- Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS().

This required touch-ups and renaming of a few existing users.

- Add Endian-dependent __counted_by_{le,be} annotations.

- Make building selftests "quieter" by printing summaries like
"CC object.o" rather than full commands with all the arguments.

Netfilter:

- Use GFP_KERNEL to clone elements, to deal better with OOM
situations and avoid failures in the .commit step.

BPF:

- Add eBPF JIT for ARCv2 CPUs.

- Support attaching kprobe BPF programs through kprobe_multi link in
a session mode, meaning, a BPF program is attached to both function
entry and return, the entry program can decide if the return
program gets executed and the entry program can share u64 cookie
value with return program. "Session mode" is a common use-case for
tetragon and bpftrace.

- Add the ability to specify and retrieve BPF cookie for raw
tracepoint programs in order to ease migration from classic to raw
tracepoints.

- Add an internal-only BPF per-CPU instruction for resolving per-CPU
memory addresses and implement support in x86, ARM64 and RISC-V
JITs. This allows inlining functions which need to access per-CPU
state.

- Optimize x86 BPF JIT's emit_mov_imm64, and add support for various
atomics in bpf_arena which can be JITed as a single x86
instruction. Support BPF arena on ARM64.

- Add a new bpf_wq API for deferring events and refactor
process-context bpf_timer code to keep common code where possible.

- Harden the BPF verifier's and/or/xor value tracking.

- Introduce crypto kfuncs to let BPF programs call kernel crypto
APIs.

- Support bpf_tail_call_static() helper for BPF programs with GCC 13.

- Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF
program to have code sections where preemption is disabled.

Driver API:

- Skip software TC processing completely if all installed rules are
marked as HW-only, instead of checking the HW-only flag rule by
rule.

- Add support for configuring PoE (Power over Ethernet), similar to
the already existing support for PoDL (Power over Data Line)
config.

- Initial bits of a queue control API, for now allowing a single
queue to be reset without disturbing packet flow to other queues.

- Common (ethtool) statistics for hardware timestamping.

Tests and tooling:

- Remove the need to create a config file to run the net forwarding
tests so that a naive "make run_tests" can exercise them.

- Define a method of writing tests which require an external endpoint
to communicate with (to send/receive data towards the test
machine). Add a few such tests.

- Create a shared code library for writing Python tests. Expose the
YAML Netlink library from tools/ to the tests for easy Netlink
access.

- Move netfilter tests under net/, extend them, separate performance
tests from correctness tests, and iron out issues found by running
them "on every commit".

- Refactor BPF selftests to use common network helpers.

- Further work filling in YAML definitions of Netlink messages for:
nftables, team driver, bonding interfaces, vlan interfaces, VF
info, TC u32 mark, TC police action.

- Teach Python YAML Netlink to decode attribute policies.

- Extend the definition of the "indexed array" construct in the specs
to cover arrays of scalars rather than just nests.

- Add hyperlinks between definitions in generated Netlink docs.

Drivers:

- Make sure unsupported flower control flags are rejected by drivers,
and make more drivers report errors directly to the application
rather than dmesg (large number of driver changes from Asbjørn
Sloth Tønnesen).

- Ethernet high-speed NICs:
- Broadcom (bnxt):
- support multiple RSS contexts and steering traffic to them
- support XDP metadata
- make page pool allocations more NUMA aware
- Intel (100G, ice, idpf):

Merge branch 'bpf-raw-tracepoint-support-for-bpf-cookie'

Andrii Nakryiko says:

====================
BPF raw tracepoint support for BPF cookie

Add ability to specify and retrieve BPF cookie for raw tracepoint programs.
Both BTF-aware (SEC("tp_btf")) and non-BTF-aware (SEC("raw_tp")) are
supported, as they are exactly the same at runtime.

This issue recently came up in production use cases, where custom tried to
switch from slower classic tracepoints to raw tracepoints and ran into this
limitation. Luckily, it's not that hard to support this for raw_tp programs.

v2->v3:
- s/bpf_raw_tp_open/bpf_raw_tracepoint_open_opts/ (Alexei, Eduard);
v1->v2:
- fixed type definition for stubs of bpf_probe_{register,unregister};
- added __u32 :u32 and aligned raw_tp fields (Jiri);
- added Stanislav's ack.

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".

Drivers:

- Ethernet high-speed NICs:
- Add a new driver for Marvell's Octeon PCI Endpoint NIC VF.
- Intel (100G, ice, idpf):
- support E825-C devices
- nVidia/Mellanox:

- optimize queue submission and wakeup handling (+17% bps)
- optimize struct layout, saving 28% of memory on queues

- Ethernet NICs embedded and virtual:
- Google cloud vNIC:

bpf: Clarify batch lookup/lookup_and_delete semantics

The batch lookup and lookup_and_delete APIs have two parameters,
in_batch and out_batch, to facilitate iterative
lookup/lookup_and_deletion operations for supported maps. Except NULL
for in_batch at the start of these two batch operations, both parameters
need to point to memory equal or larger than the respective map key
size, except for various hashmaps (hash, percpu_hash, lru_hash,
lru_percpu_hash) where the in_batch/out_batch memory size should be
at least 4 bytes.

Document these semantics to clarify the API.

libbpf: Make remark about zero-initializing bpf_*_info structs

In some situations, if you fail to zero-initialize the
bpf_{prog,map,btf,link}_info structs supplied to the set of LIBBPF
helpers bpf_{prog,map,btf,link}_get_info_by_fd(), you can expect the
helper to return an error. This can possibly leave people in a
situation where they're scratching their heads for an unnnecessary
amount of time. Make an explicit remark about the requirement of
zero-initializing the supplied bpf_{prog,map,btf,link}_info structs
for the respective LIBBPF helpers.

Internally, LIBBPF helpers bpf_{prog,map,btf,link}_get_info_by_fd()
call into bpf_obj_get_info_by_fd() where the bpf(2)
BPF_OBJ_GET_INFO_BY_FD command is used. This specific command is
effectively backed by restrictions enforced by the
bpf_check_uarg_tail_zero() helper. This function ensures that if the
size of the supplied bpf_{prog,map,btf,link}_info structs are larger
than what the kernel can handle, trailing bits are zeroed. This can be
a problem when compiling against UAPI headers that don't necessarily
match the sizes of the same underlying types known to the kernel.

====================
pull-request: bpf-next 2024-01-26

We've added 107 non-merge commits during the last 4 day(s) which contain
a total of 101 files changed, 6009 insertions(+), 1260 deletions(-).

The main changes are:

1) Add BPF token support to delegate 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. With addressed changes from Christian
and Linus' reviews, from Andrii Nakryiko.

2) Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops type,
from Kui-Feng Lee.

3) Add support for retrieval of cookies for perf/kprobe multi links,
from Jiri Olsa.

4) Bigger batch of prep-work for the BPF verifier to eventually support
preserving boundaries and tracking scalars on narrowing fills,
from Maxim Mikityanskiy.

5) Extend the tc BPF flavor to support arbitrary TCP SYN cookies to help
with the scenario of SYN floods, from Kuniyuki Iwashima.

6) Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF objects,
from Hou Tao.

7) Extend BPF verifier to track aligned ST stores as imprecise spilled
registers, from Yonghong Song.

8) Several fixes to BPF selftests around inline asm constraints and
unsupported VLA code generation, from Jose E. Marchesi.

9) Various updates to the BPF IETF instruction set draft document such
as the introduction of conformance groups for instructions,
from Dave Thaler.

10) Fix BPF verifier to make infinite loop detection in is_state_visited()
exact to catch some too lax spill/fill corner cases,
from Eduard Zingerman.

11) Refactor the BPF verifier pointer ALU check to allow ALU explicitly
instead of implicitly for various register types, from Hao Sun.

12) Fix the flaky tc_redirect_dtime BPF selftest due to slowness
in neighbor advertisement at setup time, from Martin KaFai Lau.

13) Change BPF selftests to skip callback tests for the case when the
JIT is disabled, from Tiezhu Yang.

14) Add a small extension to libbpf which allows to auto create
a map-in-map's inner map, from Andrey Grafin.
