* Add a sanity check on packet header lengthFrancois-Xavier Le Bail2018-02-071-0/+0
| | | | | | | | | | | | | | | | | | The packet length must be <= MAXIMUM_SNAPLEN. Currently, there is no D-Bus printer, thus no need for a bigger length. Now a pachet is valid if: capture length != 0, packet length != 0, capture length <= MAXIMUM_SNAPLEN, packet length <= MAXIMUM_SNAPLEN, packet length >= capture length. Moreover: Fix the packet header lengths of some fuzzed pcap files: If the lengths are > MAXIMUM_SNAPLEN, set them to MAXIMUM_SNAPLEN. Thus they will be always usable with this new sanity check.
* Fix the pcap version in some tests/ fuzzed pcap filesFrancois-Xavier Le Bail2017-01-181-0/+0
| | | | | | They will be always usable with the upcoming libpcap versions sanity checks. pcap: old version: 12336.12336, new version: 2.4 pcap-ng: old version: 1.12336, new version: 1.0
