Description

Found error in the haproxy protocol parser
Does not properly parsed

$rcv(rcvip)
$rcv(srcport)
$rcv(rcvport)

Reproduction

This can be tested suing config file

#!define IPV6_ADDR ::1

tcp_accept_haproxy=yes
received_route_mode=1

listen=tcp:[IPV6_ADDR]:45060

loadmodule "xlog.so"
loadmodule "pv.so"

event_route[core:msg-received] {
        xerr("Source IP: $rcv(srcip)\n");
        xerr("Received socket: $rcv(rcvip)\n");
        xerr("Source port: $rcv(srcport)\n");
        xerr("Received port: $rcv(rcvport)\n");
}

request_route {
        drop;
}

Then required send call via haproxy server

sipp -l 1 -m 1 -t t1 -sn uac [2600::5]
