importance. commit: cab33b7a0acba7d2268a23c4383be6167106e549 Update ND_TTEST2 to fix issue 443 Add IS_NOT_NEGATIVE macro. Avoid these warnings: - comparison of unsigned expression >= 0 is always true [-Wtype-limits], - comparison is always true due to limited range of data type [-Wtype-limits].

Upstream fixes for issues found with afl (Issue #417).

- Fix length checking. Check both the captured length and the on-the-wire length (the latter *should* be greater than or equal to the former, but that's not guaranteed). Add some additional length checks, so neither caplen nor length underflow. If we stop dissecting because the packet is too short, return 1, not 0, as we've "dissected" what we can; 0 means "this is LLC+SNAP with an OUI of 0 and an unknown Ethertype". commit: 743bcecdc92f88b118ec7aac4f68b606601205cc - Clean up length checks. Check only the amount of length that matters at any given point; yes, this means we do multiple checks, but so it goes. We don't need to check for LLC+SNAP - llc_print() does that for us. We do, however, need to check to make sure we can safely skip the Fore header. commit: 5c65e7532fa16308e01299988852b0dc5b027559

Check whether the version field is available before looking at it. While we're at it, use ND_TCHECK(), rather than a hand-rolled check, to check whether we have the full fixed-length portion of the IPv4 header. commit c67afe913011138a2504ec4d3d423b48e73b12f3 Do more length checking. From OpenBSD. commit d7516761f9c4877bcb05bb6543be3543e165249
