Daniel Borkmann 03e69b508b ebpf: add prandom helper for packet sampling ... This work is similar to commit 4cd3675ebf ("filter: added BPF random opcode") and adds a possibility for packet sampling in eBPF. Currently, this is only possible in classic BPF and useful to combine sampling with f.e. packet sockets, possible also with tc. Example function proto-type looks like: u32 (*prandom_u32)(void) = (void *)BPF_FUNC_get_prandom_u32; Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: David S.
