cd3c9634c8 Add user-space networking stack API (usrsock) 
User-space networking stack API allows user-space daemon to
provide TCP/IP stack implementation for NuttX network.

Main use for this is to allow use and seamless integration of
HW-provided TCP/IP stacks to NuttX.

For example, user-space daemon can translate /dev/usrsock
API requests to HW TCP/IP API requests while rest of the
user-space can access standard socket API, with socket
descriptors that can be used with NuttX system calls.

338b915008 While working with version 7.10 I discovered a problem in TCP stack that could be observed on high network load. Generally speaking, the problem is that RST flag is set in unnecessary case, in which between loss of some TCP packet and its proper retransmission, another packets had been successfully sent. The scenario is as follows: NuttX did not receive ACK for some sent packet, so it has been probably lost somewhere. But before its retransmission starts, NuttX is correctly issuing next TCP packets, with sequence numbers increasing properly. When the retransmission of previously lost packet finally succeeds, tcp_input receives the accumulated ACK value, which acknowledges also the packets sent in the meantime (i.e. between unsuccessful sending of lost packet and its proper retransmission). However, variable unackseq is still set to conn->isn + conn->sent, which is truth only if no further packets transmission occurred in the meantime. Because of incorrect (in such specific case) unackseq value, few lines further condition if (ackseq <= unackseq)is not met, and, as a result, we are going to reset label. 2016-06-20 06:55:29 -06:00

49e5cc5a6f TCP: check for an active connection before cleaning it up 
If there is no active connection (e.g. it is waiting in accept), then
the connection object, which doesn't yet exist, should not be cleaned
up when the socket is closed.

5e3023bef1 TCP: return from write when there is no buffer space 
During a write, if there is no more buffer space for the user data,
return the amount that was written instead of waiting until there
is free space.  If nothing has been written yet, then block as before.

This solves a deadlock that occurs if the user data is too large to
fit in the available buffer:  the write thread will block before any
data is added to the write queue, leaving no possibility that more
buffers will free up when they are ACKed (since they have not yet been
sent).  The write thread will then block forever and hold all of the
buffers.

df211ee46a TCP: add writable check during poll 
When a poll requesting POLLOUT happens, the poll should return
immediately if a write will not block.  This change adds that, as
opposed to the old behaviour of blocking until a timer from the
Ethernet driver eventually triggers the poll to complete.

This is only implemented for buffered TCP.  Unbuffered TCP should
behave as before.

0e2986f131 net/tcp: The logic that binds a specific networkd device to a connection was faulty for the case of multiple network devices. On bind(), the local address should be used to associate a device with the connection (if the local address is not INADDR_ANY); On connect(), the remote address should be used (in case the local address is INADDR_ANY). On accept(), it does not matter but the remote address is the one guarenteed to be available. 2015-09-02 19:48:31 -06:00

b1e09d4847 net/socket and net/tcp: Fix a problem in whent there are multiple network devices. Polls were being sent to all TCP sockets before. This is not good because it means that packets may sometimes be sent out on the wrong device. That is inefficient because it will cause retransmissions and bad performance. But, worse, when one of the devices is not Ethernet, it will have a different MSS and, as a result, incorrect data transfers can cause crashes. The fix is to lock into a single device once the MSS is locked locked down. 2015-08-27 09:06:46 -06:00

33085cb309 Networking: The network device list was protected by a re-entrant semaphore. With the recent change to support network device callback, the network stack needs to access the network device list too. Some drivers, however, run the network stack from the interrupt level -- this is bad but a fact in the current state. Of course,those drivers are unable to take the semaphore and will assert. 
The solution here is to eliminate the device devices semaphore altogether.  This eliminates netdev_semtake() and netdev_semgive() and replaces them with net_lock() and net_unlock() which have larger scope as needed for this purpose.

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.

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

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.

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. The notifying socket will be configured as either PF_INET or PF_INET6 and must look up the correct driver using the correct IP domain. 2015-01-17 08:33:14 -06:00

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).

6e04518e4a If CONFIG_NET_ARP_SEND is enabled, then all ICMP, TCP, and UDP send operations will call arp_send() before attempting the real send operation. arp_send() will check if the the IP address mapping is in the ARP table and, if not send ARP requests periodically until it is. This eliminates losing the first outgoing message because there is not mapping in the ARP table. 2014-08-18 16:22:14 -06:00
