Closed csujedihy closed 3 years ago

csujedihy commented 3 years ago

https://github.com/microsoft/etl2pcapng/commit/870232e9dbff6e053df350e0018009cd5a28d1ee introduced a bug where TotalLength in PcapNgWriteEnhancedPacket is incorrectly calculated which leads to corrupt blocks in pcap. Specifically, sizeof(option end) is added twice to TotalLength.
