[PATCH v1 0/8] Various fixes around undefined behavior

[Ian Rogers]

Fix various undefined behavior issues, improve tests to make them
easier to diagnose and add assertions so that problems don't recur.

Ian Rogers (8):
  perf disasm: Avoid undefined behavior in incrementing NULL
  perf test trace_btf_enum: Skip if permissions are insufficient
  tools headers: Update offsetof and container_of
  perf evsel: Avoid container_of on a NULL leader
  tools headers: Add non-NULL assert to container_of
  perf maps: Avoid UB passing NULL to bsearch
  perf test shell lock_contention: Extra debug diagnostics
  libperf event: Ensure tracing data is multiple of 8 sized
