Daniel Borkmann 20182390c4 bpf: fix replace_map_fd_with_map_ptr's ldimm64 second imm field ... Non-zero imm value in the second part of the ldimm64 instruction for BPF_PSEUDO_MAP_FD is invalid, and thus must be rejected. The map fd only ever sits in the first instructions' imm field. None of the BPF loaders known to us are using it, so risk of regression is minimal. For clarity and consistency, the few insn->{src_reg,imm} occurrences are rewritten into insn[0].{src_reg,imm}. Add a test case to the BPF selftest suite as well.
