5337176cdf Networking: setsockopt() fails when setting timeouts to values less that an 100 msec. That is because the timeout is limited to stops of 1 decisecond and because the conversion of structure timeval was truncating the microsecond remainder. The utility net_timeval2dsec now accespts and option to determin how it handles the remainder: truncate, discarding the remainder, use the remainder to round to the closed decisecond value, or use any non-zero remainder to the next larger whole decisecond value. 
For the setsockopt() case, it will always use the final option.  This means that a time of zero (i.e., not timeout) can only occur if the value zero was explicated provided to setsockopt().

d319b7c6f0 Networking: PKT logic now uses the device event list 2015-05-28 12:40:05 -06:00
Gregory Nutt
e81f279315 Networking: Modify event list handling: Now there are two event lists each device structure: (1) One is for ARP and ICMP data related evetns, the other is for device related events. Callback allocation/free routines no accept a device paramter as well as a list: If the device paramter is added, then the callback goes into both the connection-related liast AND the device event list. Thus each socket type can received both custom data-related events as well as common device related events. 2015-05-28 12:01:38 -06:00

01d176af76 net_startmonitor.c always returned zero. In the case where a socket has already been closed, it correctly handled the disconnetion event but still returned OK. Returning OK causes the callers of net_startmonitor to assume that the connection was okay, undoing the good things that net_startmonitor did and causing the socket to be marked as connected. This behavior was noted by Pelle Windestam. 2015-05-28 08:23:51 -06:00

4fd0192a3e Networking: No that ARP, ICMP, and ICMPv6 reside in the same list we need to make the definitions of ARP_POLL, ICMP_POLL, and ICMPv6_POLL different because there are small differences in the context for each. 2015-05-27 15:04:51 -06:00

0f5c35260b Local sockets: Local stream sockets had problem of double releasing pipes (both server and client attempt release), which causes wrong pipe pair being closed in multi-client case.

1f3ee83134 Increase the size of the number of bytes sent from uint16_t to uint32_t in order to avoid TCP errors with long sessions. For exmple: 
int hello_main(int argc, char *argv[])
{
   uint32_t i;
   for(i = 0; i < 65536; i++)
    {
      printf("Hello, World!!\n");
    }

  printf("press any key!!\n");
  if (getchar()=='t')
    return 0;
  else
    return 1;
}

When ran in a Telnet session, the "press any key" is not displayed because the tcp session closed unexpectedly with:

tcp_input: ERROR: conn->sndseq xx, conn->unacked xx"

This is fixed by increasing the width of conn->sent to 32-bits to prevent overflow.
