[bpf-next,v2,0/9] bpf: RLIMIT_MEMLOCK cleanups

Message

Yafang Shao April 3, 2022, 2:42 p.m. UTC

We have switched to memcg based memory accouting and thus the rlimit is
not needn't any more. LIBBPF_STRICT_AUTO_RLIMIT_MEMLOCK is introduced in
libbpf for backward compatibility, so we can use it instead now.

v2: use libbpf_set_strict_mode instead. (Andrii)
v1: https://lore.kernel.org/bpf/[e-mail]/

Yafang Shao (9):
  bpf: selftests: Use libbpf 1.0 API mode in bpf constructor
  bpf: selftests: Use bpf strict all ctor in xdping
  bpf: selftests: Use bpf strict all ctor in xdpxceiver
  bpf: samples: Replace RLIMIT_MEMLOCK with LIBBPF_STRICT_ALL in
    xdpsock_user
  bpf: samples: Replace RLIMIT_MEMLOCK with LIBBPF_STRICT_ALL in xsk_fwd
  bpf: runqslower: Replace RLIMIT_MEMLOCK with LIBBPF_STRICT_ALL
  bpf: bpftool: Remove useless return value of libbpf_set_strict_mode
  bpf: bpftool: Set LIBBPF_STRICT_AUTO_RLIMIT_MEMLOCK for legacy libbpf
  bpf: bpftool: Remove useless rlimit setting
