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.

21545ab643 net/local: connect: Fix warning with gcc-arm-none-eabi-5-2016q1. Using compiler from gcc-arm-none-eabi-5-2016q1 toolchain: 
gcc version 5.3.1 20160307 (release) [ARM/embedded-5-branch revision 234589] (GNU Tools for ARM Embedded Processors)

gives error:

  local/local_connect.c:188:7: error: '_local_semtake' is static but used in inline function 'local_stream_connect' which is not static [-Werror]

this is due to compiler enforcing ISO/IEC 9899:1999 6.7.4.3:  "An inline definition of a function with external linkage shall not contain a definition of a modifiable object with static storage duration, and shall not contain a reference to an identifier with internal linkage."

Fix by making inlined caller to have internal linkage as well.

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

bd3ef36eda SUMMARY 
-------
   This patch enhances networking support for the simulation under Linux.
   Includes updated support for Linux TUN/TAP, and the addition of support for
   Linux bridge devices.

CHANGES
-------
   o Check to see if the d_txavail callback is present before calling it in
     the arp send code.  This prevents a segfault when simulating the telnetd
     daemon with arp send enabled.

   o Adjust the simulation's netdriver_loop() so it will detect and respond to
     ARP requests.

   o Do not attempt to take the tap device's hardware address for use by the
     simulation.  That hardware address belongs to the host end of the link,
     not the simulation end.  Generate a randomized MAC address instead.

   o Do not assign an IP address to the interface on the host side of the TAP
     link.

   + Provide two modes: "host route" and "bridge".

   + In host route mode, maintain a host route that points any traffic for the
     simulation's IP address to the tap device.  In this mode, so long as the
     simulation's IP is a free address in the same subnet as the host, no
     additional configuration will be required to talk to it from the host.
     Note that address changes are handled automatically if they follow the
     rule of if-down/set-address/if-up, which everything seems to.

   + In bridge mode, add the tap device to the specified bridge instance.  See
     configs/sim/NETWORK-LINUX.txt for information and usage examples.  This
     enables much more flexible configurations (with fewer headaches), such as
     running multiple simulations on a single host, all of which can access
     the network the host is connected to.

   o Refresh configurations in configs/sim where CONFIG_NET=y.  They default
     to "host route" mode.

   o Add configs/sim/NETWORK-LINUX.txt

CAVEATS
-------
   - The MAC address generation code is extremely simplistic, and does not
     check for potential conflicts on the network.  Probably not an issue, but
     something to be aware of.

   - I was careful to leave it in a state where Cygwin/pcap should still work,
     but I don't have a Windows environment to test in.  This should be
     checked.

   - I don't know if this was ever intended to work with OS X.  I didn't even
     try to test it there.

NOTES
-----
   - Was able to get telnetd working and simulate nsh over telnet, but only so
     long as listen backlogs were disabled.

     There appears to be a bug in the backlog code where sockets are being
     returned in SYN_RCVD state instead of waiting until they're ESTABLISHED;
     if you perform an immediate send after accepting the connection, it will
     confuse the stack and the send will hang; additionally, the connection
     will never reach ESTABLISHED state.

     Can be worked around by adding a sleep(1) after the accept in telnetd.  I
     don't have the necessary knowledge of the IP stack to know what the
     correct fix is.

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.
 2016-01-22 16:22:09 -06:00
Andrew Webster
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.
 2016-01-22 16:19:20 -06:00
Andrew Webster
e221777a7a TCP: post buffer semaphore before re-acquiring both 
TCP uses two semaphores for buffers, one for the entire buffer pool,
and one for the number of allowed buffers for readahead.  To avoid
double taking a semaphore under heavy load, release the semaphore
after waiting before trying to acquire both again.
 2016-01-22 16:15:10 -06:00
Andrew Webster
4875c6bbe3 TCP: check for connection before deleting it 
It is possible for a socket to have no connection, for example if a TCP
socket is waiting in accept.  This checks for this condition in case the
socket is closed from a different thread.
 2016-01-22 15:59:15 -06:00
Andrew Webster
f1ef2c6cde TCP: attempt to flush the write buffers before closing 
When a socket is closed, it should make sure that any pending write
data is sent before the FIN is sent.  It already would wait for all
sent data to be acked, however it would discard any pending write
data that had not been sent at least once.

This change adds a check for pending write data in addition to unacked
data.  However, to be able to actually send any new data, the send
callback must be left.  The callback should be freed later when the socket
is actually destroyed.

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.

This change standardizes the driver statistics and puts the definition in the common network device structure defined in netdev.h where they can be accessed by network applications. All Ethernet drivers that collect statistics have been adapted to use these common statistics. 2015-11-26 12:08:09 -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

b493dde4cf TCP networking: In the TCP connection operation, it was trying to setup the network monitor BEFORE the socket was successfully connected. This, of course, has ALWAYS failed because the socket is not yet connected and the TCP state is not yet correct for a connected socket. However, because of other changes net_startmonitor(0 no returns a failure condition that causes worse problems when trying to connect. The fix is to move the logic that starts the network monitor to AFTER the socket has been successfully connected. 2015-05-31 11:35:28 -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.

cc340aaa92 TCP networking: Since the network monitor now allocates a callback structure, it is critical to make sure that the networking monitor is stopped when the socket is closed or any other loss of connection. What was innocuous before would now be a memory leak 2015-05-30 11:49:55 -06:00
