Function parse_icmpv6

fn parse_icmpv6(
    packet_bytes: &[u8],
    measurement_id: u32,
    origin_map: &Vec<Origin>,
) -> Option<(Reply, bool)>

Parse ICMPv6 packets (including v6 headers) into a Reply result.

Filters out spoofed packets and only parses ICMP echo replies valid for the current measurement.

Arguments

• packet_bytes - the bytes of the packet to parse

• measurement_id - the ID of the current measurement

• origin_map - mapping of origin to origin ID

Returns

• Option<Reply> - the received ping reply

Remarks

The function returns None if the packet is not an ICMP echo reply or if the packet is too short to contain the necessary information.

The function also discards packets that do not belong to the current measurement.
