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)
Drivers:

bpf, docs: Address comments from IETF Area Directors
This patch does the following to address IETF feedback:
* Remove mention of "program type" and reference future docs (and mention platform-specific docs exist) for helper functions and BTF. Addresses Roman Danyliw's comments based on GENART review from Ines Robles [0].
* Add reference for endianness as requested by John Scudder [1].
* Added bit numbers to top of 32-bit wide format diagrams as requested by Paul Wouters [2].
* Added more text about why BPF doesn't stand for anything, based on text from ebpf.io [3], as requested by Eric Vyncke and Gunter Van de Velde [4].
* Replaced "htobe16" (and similar) and the direction-specific description with just "be16" (and similar) and a direction-agnostic description, to match the direction-agnostic description in the Byteswap Instructions section. Based on feedback from Eric Vyncke [5].

In the Jump instructions section it explains that the offset is "relative to the instruction following the jump instruction". But the program-local section confusingly said "referenced by offset from the call instruction, similar to JA".

bpf, docs: clarify sign extension of 64-bit use of 32-bit imm
imm is defined as a 32-bit signed integer.
{MOV, K, ALU64} says it does "dst = src" (where src is 'imm') and it does do dst = (s64)imm, which in that sense does sign extend imm. The MOVSX instruction is explained as sign extending, so added the example of {MOV, K, ALU64} to make this more clear.
{JLE, K, JMP} says it does "PC += offset if dst <= src" (where src is 'imm', and the comparison is unsigned). This was apparently ambiguous to some readers as to whether the comparison was "dst <= (u64)(u32)imm" or "dst <= (u64)(s64)imm" so added an example to make this more clear.

bpf, docs: Use RFC 2119 language for ISA requirements
Per IETF convention and discussion at LSF/MM/BPF, use MUST etc. keywords as requested by IETF Area Director review. Also as requested, indicate that documenting BTF is out of scope of this document and will be covered by a separate IETF specification.
Added paragraph about the terminology that is required IETF boilerplate and must be worded exactly as such.

bpf, docs: Move sentence about returning R0 to abi.rst
As discussed at LSF/MM/BPF, the sentence about using R0 for returning values from calls is part of the calling convention and belongs in abi.rs
bpf, docs: Move sentence about returning R0 to abi.rst
As discussed at LSF/MM/BPF, the sentence about using R0 for returning values from calls is part of the calling convention and belongs in abi.rst. Any further additions or clarifications to this text are left for future patches on abi.rst. The current patch is simply to unblock progression of instruction-set.rst to a standard.
In contrast, the restriction of register numbers to the range 0-10 is untouched, left in the instruction-set.rst definition of the src_reg and dst_reg fields.
