Merge branch 'fix-bpf-multi-uprobe-pid-filtering-logic'
Andrii Nakryiko says:
====================
Fix BPF multi-uprobe PID filtering logic
It turns out that current implementation of multi-uprobe PID filtering logic
is broken. It filters by thread, while the promise is filtering by process.
Patch #1 fixes the logic trivially. The rest is testing and mitigations that
are necessary for libbpf to not break users of USDT programs.
v1->v2:
- fix selftest in last patch (CI);
- use semicolon in patch #3 (Jiri).
