Per discussion at Kernel Summit. Every new syscall requires
a manual page and test programs. We have had too many new syscalls
that are DOA.
There is verifier testsuite that is testing eBPF verifier from userspace
via bpf syscall. Also there are multiple examples and libbpf.
I think test coverage for bpf syscall is quite substantial already.
This is in tools/bpf/, right?
No, it contains a BPF JIT disasm, bpf assembler and a debugger, but the
last two are for the 'classic' BPF interface only. There's a test suite
for BPF/eBPF in general under lib/test_bpf.c, but so far it tests only
the current code w/o eBPF verifier.
That said, I think Alexei is referring to the examples et al from the
bigger previous proposed patch set.
