This should do it:
Change readip_rawrecv in rawrecv.c to this:
[note to fyodor: I'm fairly sure I already sent you this]
char *rawrecv_readip(pcap_t *pd, unsigned int *len, long to_usec)
{
int rcvlen;
DWORD time1, time2;
fd_set fds;
TIMEVAL tv;
if(-2 != (long)pd)
fatal("rawrecv_readip: called with non-rawrecv handle\n");
begin:
// Note: I could use SO_RCVTIMEO but I don't trust it...
time1 = GetTickCount();
FD_ZERO(&fds);
FD_SET(s, &fds);
tv.tv_usec = to_usec % 1000000;
tv.tv_sec = to_usec / 1000000;
if(0 == select(0, &fds, 0, 0, &tv))
{
if(len) *len = 0;
return 0;
}
rcvlen = recv(s, buf, sizeof(buf), 0);
time2 = GetTickCount() + 10;
if(rcvlen > 0)
{
if(rcvlen >= sizeof(struct ip) && filter(buf, rcvlen))
{
if(len) *len = rcvlen;
return buf;
}
else
{
to_usec -= 1000 * (time2 - time1);
if(to_usec < 0)
{
if(len) *len = 0;
return 0;
}
goto begin;
}
}
else
{
DWORD err = WSAGetLastError();
if(err != WSAETIMEDOUT && err != WSAEWOULDBLOCK)
fatal("rawrecv: recv failed (%lu)\n", err);
if(len) *len = 0;
return 0;
}
}
