[PATCH bpf-next 0/4] bpf: Follow up on the patch list

[Qiliang Yuan]

Alexei listed what the patch list series [1] still needed when he
applied it [2]. This series covers items 1, 2, 3 and 5 of that list:

  item  problem                                           patch
  1     the tests break with bpf_jit_harden at 2          2
  2     the out-of-range test ignores the insn number     3
  3     the comments on the aux data rules are gone       1
  5     no test has a second patch with a jump            4

Item 4 is about a commit log that is already in the tree. Items 10-12,
bugs that were there before the series, come as separate fixes.

With net.core.bpf_jit_harden at 0 and at 2 before the run,
verifier_patch_list and patch_list pass and leave the sysctl as it
was. Without patch 2 and with the sysctl at 2, 8 verifier_patch_list
tests and patch_list/line_and_func_info fail. test_verifier and
test_progs show no new failures.
