[PATCH 0/7] validate-bpf: add standalone validation debug tool

[Marat Khalili <marat.khalili@huawei.com>]

This patchset introduces a new standalone tool for pre-validating eBPF
programs and debugging validation problems. Its should allow developers
to trace validator state changes per instruction and understand verifier
decisions, simplifying the debugging of rejected programs before loading
them into a real application context.

Marat Khalili (7):
  bpf/validate: fix finished status on restart
  bpf/validate: refactor internal step function
  bpf/validate: formalize call back requirements
  bpf/validate: add jump notification events
  bpf/validate: add get current event API
  app/test: add test for bpf validate debug events
  app/validate-bpf: add BPF validation application
