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
