Fix PacketCapture pcapng file issue on macOS #6804

Closed hangyan closed 1 week ago

hangyan commented 2 weeks ago

By default, gopacket will write snap length=0 in the pcapng file header, means unlimited snaplen. tcpdump on osx(libpcap version 1.10.1) cannot recognize this and will report error. This patch will set a default value(524288) for it. This patch also add packets file verification in e2e tests.

origin error message:

tcpdump: pcap_loop: invalid packet capture length 74, bigger than snaplen of 524288

pcapng format ref: https://pcapng.com/
