Alexei Starovoitov 3c2611bac0 selftests/bpf: Fix trace_virtqueue_add_sgs test issue with LLVM 17. ... LLVM commit https://reviews.llvm.org/D143726 introduced hoistMinMax optimization that transformed (i < VIRTIO_MAX_SGS) && (i < out_sgs) into i < MIN(VIRTIO_MAX_SGS, out_sgs) and caused the verifier to stop recognizing such loop as bounded. Which resulted in the following test failure: libbpf: prog 'trace_virtqueue_add_sgs': BPF program load failed: Bad address libbpf: prog 'trace_virtqueue_add_sgs': -- BEGIN PROG LOAD LOG -- The sequence of 8193 jumps is too complex. verification time 789206 usec stack depth 56 processed 156446 insns (limit 1000000) max_states_per_insn 7 total_states 1746 peak_states 1701 mark_read 12 -- END PROG LOAD LOG -- libbpf: prog 'trace_virtqueue_add_sgs': failed to load: -14 libbpf: failed to load object 'loop6.bpf.o' Workaround the verifier limitation for now with inline asm that prevents this particular optimization.
