[PATCH bpf-next 0/4] Preparatory libbpf fixes and clean ups

[Andrii Nakryiko <andrii@kernel.org>]

Few fixes and clean up in preparation for finalizing libbpf 1.0.

Main change is switching libbpf to initializing only relevant portions of
union bpf_attr for any given BPF command. This has been on a wishlist for
a while, so finally this is done. While cleaning this up, I've also cleaned up
few other placed were we didn't use explicit memset() with kernel UAPI structs
(perf_event_attr, bpf_map_info, bpf_prog_info, etc).

Also few fixes to test_progs that came up while testing selftests in release
mode.


Andrii Nakryiko (4):
  libbpf: fix potential NULL dereference when parsing ELF
  libbpf: streamline bpf_attr and perf_event_attr initialization
  libbpf: clean up deprecated and legacy aliases
  selftests/bpf: few fixes for selftests/bpf built in release mode
