bpf, verifier: fix register type dump in xadd and st
Using reg_type_str[insn->dst_reg] is incorrect since insn->dst_reg contains the register number but not the actual register type. Add a small reg_state() helper and use it to get to the type. Also fix up the test_verifier test cases that have an incorrect errstr. Fixes: 9d2be44a7f33 ("bpf: Reuse canonical string formatter for ctx errs") Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
