pull-request: bpf-next 2023-06-23

We've added 49 non-merge commits during the last 24 day(s) which contain
a total of 70 files changed, 1935 insertions(+), 442 deletions(-).

The main changes are:

1) Extend bpf_fib_lookup helper to allow passing the route table ID,
   from Louis DeLosSantos.

2) Fix regsafe() in verifier to call check_ids() for scalar registers,
   from Eduard Zingerman.

3) Extend the set of cpumask kfuncs with bpf_cpumask_first_and()
   and a rework of bpf_cpumask_any*() kfuncs. Additionally,
   add selftests, from David Vernet.

4) Fix socket lookup BPF helpers for tc/XDP to respect VRF bindings,
   from Gilad Sever.

5) Change bpf_link_put() to use workqueue unconditionally to fix it
   under PREEMPT_RT, from Sebastian Andrzej Siewior.

6) Follow-ups to address issues in the bpf_refcount shared ownership
   implementation, from Dave Marchevsky.

7) A few general refactorings to BPF map and program creation permissions
   checks which were part of the BPF token series, from Andrii Nakryiko.

8) Various fixes for benchmark framework and add a new benchmark
   for BPF memory allocator to BPF selftests, from Hou Tao.

9) Documentation improvements around iterators and trusted pointers,
   from Anton Protopopov.

10) Small cleanup in verifier to improve allocated object check,
    from Daniel T. Lee.

11) Improve performance of bpf_xdp_pointer() by avoiding access
    to shared_info when XDP packet does not have frags,
    from Jesper Dangaard Brouer.

12) Silence a harmless syzbot-reported warning in btf_type_id_size(),
    from Yonghong Song.

13) Remove duplicate bpfilter_umh_cleanup in favor of umd_cleanup_helper,
    from Jarkko Sakkinen.

14) Fix BPF selftests build for resolve_btfids under custom HOSTCFLAGS,
    from Viktor Malik.
