Subject: pull-request: bpf-next 2024-04-29

Hi David, hi Jakub, hi Paolo, hi Eric,

The following pull-request contains BPF updates for your *net-next* tree.

We've added 147 non-merge commits during the last 32 day(s) which contain
a total of 158 files changed, 9400 insertions(+), 2213 deletions(-).

Note, the merge is conflict-free. There is a small conflict once net lands
in net-next, see also:

  https://lore.kernel.org/bpf/20240429114939.210328b0@canb.auug.org.au

The main changes are:

1) Add an internal-only BPF per-CPU instruction for resolving per-CPU memory addresses and
   implement support in x86 BPF JIT. This allows inlining per-CPU array and hashmap lookups
   and the bpf_get_smp_processor_id() helper, from Andrii Nakryiko.

2) Add BPF link support for sk_msg and sk_skb programs, from Yonghong Song.

3) 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, from Alexei Starovoitov.

4) Add support for passing mark with bpf_fib_lookup helper, from Anton Protopopov.

5) Add a new bpf_wq API for deferring events and refactor sleepable bpf_timer code to keep
   common code where possible, from Benjamin Tissoires.

6) Fix BPF_PROG_TEST_RUN infra with regards to bpf_dummy_struct_ops programs to check
   when NULL is passed for non-NULLable parameters, from Eduard Zingerman.

7) Harden the BPF verifier's and/or/xor value tracking, from Harishankar Vishwanathan.

8) Introduce crypto kfuncs to make BPF programs able to utilize the kernel crypto subsystem,
   from Vadim Fedorenko.

9) Various improvements to the BPF instruction set standardization doc, from Dave Thaler.

10) Extend libbpf APIs to partially consume items from the BPF ringbuffer, from Andrea Righi.

11) Bigger batch of BPF selftests refactoring to use common network helpers and to drop
    duplicate code, from Geliang Tang.

12) Support bpf_tail_call_static() helper for BPF programs with GCC 13, from Jose E. Marchesi.

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

14) Allow invoking BPF kfuncs from BPF_PROG_TYPE_SYSCALL programs, from David Vernet.

15) Extend the BPF verifier to allow different input maps for a given bpf_for_each_map_elem()
    helper call in a BPF program, from Philo Lu.

16) Add support for PROBE_MEM32 and bpf_addr_space_cast instructions for riscv64 and arm64
    JITs to enable BPF Arena, from Puranjay Mohan.

17) Shut up a false-positive KMSAN splat in interpreter mode by unpoison the stack
    memory, from Martin KaFai Lau.

18) Improve xsk selftest coverage with new tests on maximum and minimum hardware ring
    size configurations, from Tushar Vyavahare.

19) Various rST man pages fixes as well as documentation and bash completion improvements
    for bpftool, from Rameez Rehman & Quentin Monnet.

20) Fix libbpf with regards to dumping subsequent char arrays, from Quentin Deslandes.
