-The error strings need to be updated, since they fail early.
+The changes to fix the CVE 2019-7308 make the bpf verifier stricter
+with respect to operations that were allowed earlier in unprivileged
+mode. Fixup the test cases so that the error messages now correctly
+reflect pointer arithmetic going out of range for tests.
