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.

a82b8fd71f Networking: Fix several build errors/warning with IPv4 + IPv6 + multiple networks are enabled. 2015-02-10 06:54:10 -06:00

b756df982d net/: Lots of build problems introduced into multiple NIC support. Many places where conditional logic based on CONFIG_NETDEV_MULTINIC is confused with CONFIG_NET_MULTILINK. Lots of code changed with IPv6 that was never compiled with MULTINIC enabled. Still some problem with parameter passing. 2015-02-09 18:15:34 -06:00

a07a764d42 ICMPv6: Adds basic logic to support verification that we have the IPv6 address in the Neighbor Table. This feature is important because otherwise the first packet sent to a remote peer will fail (it will be replaced with a Neighbor Solicitation). 2015-02-02 13:44:31 -06:00

371a9fd84c Networking: Fix another deadlock condition. tcp_write_buffer_alloc() calls sem_wait() with network locked. That worked if CONFIG_NET_NOINTS was not defined because interrupts are automatically restored when the wait happens. But with CONFIG_NET_NOINTS=y, the wait blocks with the network locked -- bad style and also can lead to a deadlock condition 2015-01-28 11:56:11 -06:00

c4bd6f52b5 Networking: The are issues with the TCP write-ahead buffering if CONFIG_NET_NOINTS is enabled: There is a possibility of deadlocks in certain timing conditions. I have not seen this with the Tiva driver that I have been users but other people claim to see the issue on other platforms. Certainly it is a logic error: The network should never wait for TCP read-ahead buffering space to be available. It should drop the packets immediately. 
This was fixed by duplicating most of the IOB interfaces:  The versions that waited are still present (like iob_alloc()), but now there are non-waiting verisons of the same interfaces (like iob_tryalloc()).  The TCP read-ahead logic now uses only these non-waiting interfaces.

4ad5998db3 net/socket and net/tcp: When we are ready to receive data or when we have outgoing data ready to be sent, we need to the notify the appropriate device driver of this condition.

2c251d845c include/net/if.h: Add a bit to the device flags to indicate if the device packet buffer holds an IPv4 or an IPv6 domain packet. Set/clear the flag along with the correct offset to the application payload data as each packet is received. 
net/socket, net/tcp, net/udp:  Add logic to select the domain of the outputgoing packet before sending any UDP or TCP packet.  This sets the bit to indicate the IPv4 or IPv6 domain and the correct offset to the output going payload data.

2663538b0a Networking: Replace all references to the macros net_ipaddr_copy, net_ipaddr_hdrcopy, net_ipaddr_cmp, net_ipaddr_hdrcmp, and net_ipaddr_maskcmp with the appropriate IPv4 or IPv6 version of the macro (such as net_ipv4addr_copy).
