====================
pull-request: bpf-next 2023-08-25

We've added 87 non-merge commits during the last 8 day(s) which contain
a total of 104 files changed, 3719 insertions(+), 4212 deletions(-).

The main changes are:

1) Add multi uprobe BPF links for attaching multiple uprobes
   and usdt probes, which is significantly faster and saves extra fds,
   from Jiri Olsa.

2) Add support BPF cpu v4 instructions for arm64 JIT compiler,
   from Xu Kuohai.

3) Add support BPF cpu v4 instructions for riscv64 JIT compiler,
   from Pu Lehui.

4) Fix LWT BPF xmit hooks wrt their return values where propagating
   the result from skb_do_redirect() would trigger a use-after-free,
   from Yan Zhai.

5) Fix a BPF verifier issue related to bpf_kptr_xchg() with local kptr
   where the map's value kptr type and locally allocated obj type
   mismatch, from Yonghong Song.

6) Fix BPF verifier's check_func_arg_reg_off() function wrt graph
   root/node which bypassed reg->off == 0 enforcement,
   from Kumar Kartikeya Dwivedi.

7) Lift BPF verifier restriction in networking BPF programs to treat
   comparison of packet pointers not as a pointer leak,
   from Yafang Shao.

8) Remove unmaintained XDP BPF samples as they are maintained
   in xdp-tools repository out of tree, from Toke Høiland-Jørgensen.

9) Batch of fixes for the tracing programs from BPF samples in order
   to make them more libbpf-aware, from Daniel T. Lee.

10) Fix a libbpf signedness determination bug in the CO-RE relocation
    handling logic, from Andrii Nakryiko.

11) Extend libbpf to support CO-RE kfunc relocations. Also follow-up
    fixes for bpf_refcount shared ownership implementation,
    both from Dave Marchevsky.

12) Add a new bpf_object__unpin() API function to libbpf,
    from Daniel Xu.

13) Fix a memory leak in libbpf to also free btf_vmlinux
    when the bpf_object gets closed, from Hao Luo.

14) Small error output improvements to test_bpf module, from Helge Deller.
