[PATCH v2 bpf-next 11/12] bpf: disallow bpf_probe_read[_str] helpers

Disallow bpf_probe_read() and bpf_probe_read_str() helpers in raw_tracepoint bpf programs that use in-kernel BTF to track types of memory accesses. Signed-off-by: Alexei Starovoitov --- kernel/trace/bpf_trace.c | 4 1 file changed, 4 insertions(+) diff --git a/kernel/trace/bpf_trace.c b/ke
