selftests: bpf: test writable buffers in raw tps
This tests that: * a BPF_PROG_TYPE_RAW_TRACEPOINT_WRITABLE cannot be attached if it uses either: * a variable offset to the tracepoint buffer, or * an offset beyond the size of the tracepoint buffer * a tracer can modify the buffer provided when attached to a writable tracepoint in bpf_prog_test_run Signed-off-by: Matt Mullins <mmullins@fb.com> Acked-by: Yonghong Song <yhs@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
