Describe the bug
TCP rewrite fails to parse input pcap file, exits with the error:
Fatal Error: Error rewriting packets: From tcpedit.c:tcpedit_packet() line 192:
Packet length 98 is to short to contain an IPv6 header for DLT 0x0001
To Reproduce
Steps to reproduce the behavior:
- Run
tcprewrite as follows:
tcprewrite -vv -i afail1.pcap -o /dev/null --pnat="9.9.0.0/16:1.1.0.0/16"
- Observe the output:
reading from file -, link-type EN10MB (Ethernet)
17:11:17.1592871077 IP6 4950:3aa3:964b:a356:60a3:7dea:a836:3200 > 4efa:695:ee19:12d9:4906:6f8b:8bbb:6bd6: frag (0|36) 63927 > domain: 0 [0q] (28)
Fatal Error: Error rewriting packets: From tcpedit.c:tcpedit_packet() line 192:
Packet length 98 is to short to contain an IPv6 header for DLT 0x0001
Expected behavior
Not to fail. Even if the packet is not parse-able, it should either (a) drop it, (b) overwrite IPs, but not checksum, (c) leave such packets as is.
