Subject: [PATCH bpf-next v11 0/7] bpf-core changes for preparation of

Hi,

well, given that the HID changes haven't moved a lot in the past
revisions and that I am cc-ing a bunch of people, I have dropped them
while we focus on the last 2 requirements in bpf-core changes.

I'll submit a HID targeted series when we get these in tree, which
would make things a lore more independent.

For reference, the whole reasons for these 2 main changes are at
https://lore.kernel.org/bpf/20220902132938.2409206-1-benjamin.tissoires@redhat.com/

Compared to v10 (in addition of dropping the HID changes), I have
changed the selftests so we can test both light skeletons and libbbpf
calls.

Cheers,
Benjamin

Benjamin Tissoires (7):
  selftests/bpf: regroup and declare similar kfuncs selftests in an
    array
  bpf: split btf_check_subprog_arg_match in two
  bpf/verifier: allow all functions to read user provided context
  selftests/bpf: add test for accessing ctx from syscall program type
  bpf/btf: bump BTF_KFUNC_SET_MAX_CNT
  bpf/verifier: allow kfunc to return an allocated mem
  selftests/bpf: Add tests for kfunc returning a memory pointer
