Gregory Nutt 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.

arp Fix some time value changes; mostly changing greater than 1000000000 to greater than or equal to 1000000000. From Juha Niskanen 2015-02-20 07:07:36 -06:00
devif Use common macro(s) for calculating link layer header length. From Brennan Ashton. 2015-04-13 13:53:13 -06:00
icmp 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
icmpv6 Use common macro(s) for calculating link layer header length. From Brennan Ashton. 2015-04-13 13:53:13 -06:00

iob IOB Configuration: Default number of IOB changes must be more than zero is UDP read-ahead is enabled. 2015-02-10 06:25:55 -06:00
local VFS: The inode unlink method should not be support if operations on the root pseudo-filesystem are disabled. 2015-02-18 09:34:58 -06:00

udp Move some useful internal logic from recvfrom.c and udp_callback.c and put them in ip.h where they can be used more generally 2015-02-17 07:37:44 -06:00

net_initialize.c Networking: Divide net_intiialize() into net_setup() and net_initialize() to solve a chicken-and-egg problem. net_setup() must be caleld before up_initialize() is called so that networking data structures are ready to register new network devices. 2015-02-14 06:36:53 -06:00
