From bf88a80a0407e67f21ceafbf03828086f149dfad Mon Sep 17 00:00:00 2001 From: Hao Luo Date: Tue, 6 Oct 2020 19:28:57 -0700 Subject: selftests/bpf: Fix test_verifier after introducing resolve_pseudo_ldimm64 Commit 4976b718c355 ("bpf: Introduce pseudo_btf_id") switched the order of check_subprogs() and resolve_pseudo_ldimm() in the verifier. Now an empty prog expects to see the error "last insn is not an the prog of a single invalid ldimm exit or jmp" instead, because the check for subprogs comes first. It's now pointless to validate that half of ldimm64 won't be the last instruction. Tested: # ./test_verifier Summary: 1129 PASSED, 537 SKIPPED, 0 FAILED and the full set of bpf selftests.
