Merge branch 'bpf-log-improvements'
Andrii Nakryiko says: ==================== This patch set fixes ambiguity in BPF verifier log output of SCALAR register in the parts that emit umin/umax, smin/smax, etc ranges. See patch #4 for details. Also, patch #5 fixes an issue with verifier log missing instruction context (state) output for conditionals that trigger precision marking. See details in the patch. First two patches are just improvements to two selftests that are very flaky locally when run in parallel mode. Patch #3 changes 'align' selftest to be less strict about exact verifier log output (which patch #4 changes, breaking lots of align tests as written). Now test does more of a register substate checks, mostly around expected var_off() values. This 'align' selftests is one of the more brittle ones and requires constant adjustment when verifier log output changes, without really catching any new issues. So hopefully these changes can minimize future support efforts for this specific set of tests. ==================== Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
