- fixed BufferQueue's RemoveUntil.
- reset SND.NXT on third duplicate ACK (fast retransmit).
- on retransmit reset SND.NXT to SND.UNA (it will be updated back when we get good ACKs).
- fixed effective window calculation.
- relaxed SWS checking a bit, don't send partial packets on retransmission as the window might have been reduced due to congestion.

- check the effective window against the flight size.
- start the RTT estimates relatively high.
- introduced a TCP PROBE debug message for offline processing and TCP debugging.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20750 a95241bf-73f2-0310-859d-f6bbb57e9c96
- support TCP fast retransmit/fast recovery.
- maintain the RTT average time and update the retransmit timeout accordingly.
- improvements to TCP Slow start / congestion avoidance.
- better handling of the retransmission timer.
- properly size segments taking the TCP options length into consideration.
- as an interim fix, update the SendQ/RecvQ sizes on Connect().

- fixed the locking for spawned connections and accept()s.
- return EMSGSIZE if the user is trying to write more data than the send buffer can hold.
- fixed a crash when receiving a RST while the connection is being closed.
- don't wake up readers when the connection gets established.
- endpoint managers lock must be recursive to properly work with spawn'ed sockets.

- TCP now behaves correctly when receiving new connections as its SYN/ACK is queued, or if lost correctly retransmitted when the peer resends a SYN.
- The first ICMP Replies from an external on-link host pinging Haiku are no longer lost.
- Reduced the number of ARP messages Haiku needs to generate until resolving an entry.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20712 a95241bf-73f2-0310-859d-f6bbb57e9c96
- In fact our SYN/ACK reply is being lost due to ARP resolving as we are waiting in the device's receive path, thus we never get replies before timing out. This requires queueing during ARP resolving.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20706 a95241bf-73f2-0310-859d-f6bbb57e9c96
- check if the destination address is specified in IPv4's SendData()
- minor cleanups to IPv4's TRACE()s.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20681 a95241bf-73f2-0310-859d-f6bbb57e9c96
- made the ipv4 raw, udp and link protocols use DatagramSocket.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20672 a95241bf-73f2-0310-859d-f6bbb57e9c96
- IPv4 now assumes the addresses it is supplied in send_routed_data are already the appropriate ones.
- made the Data(), operator* and operator-> methods in NetBufferFieldReader const so we can use them in the same expression as the constructor.
- fixed an issue with UDP where the wrong source address could be used in the calculating the checksum.
- changed ipv4_print_address to use the more common 0.0.0.0 format.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20660 a95241bf-73f2-0310-859d-f6bbb57e9c96
- introduced base NetBufferFieldReader which deals with obtaining a continuguous field to deal with.
- renamed Detach() to Sync() to better express the fact that we may be writing to the buffer.
- Fixed IPv4's and ICMP's checksum calculation as it assumed the underlying header was contiguous.
- ICMP is now able to reply to ICMP Echo Requests which were split across data nodes.
- in split_buffer(), make sure we were able to trim() the new buffer before damaging the original one.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20657 a95241bf-73f2-0310-859d-f6bbb57e9c96
- don't try to remove spawned sockets from Endpoints hashtable.
- return B_WOULD_BLOCK (EAGAIN) when we time out in acquire_sem().
- use B_RELEASE_IF_WAITING_ONLY in the TCP WaitList.
- fixed a off by one issue in ReadData() which could result in more than needed iterations (and waiting).
- implemented prepending new buffers to a net_buffer.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20639 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Properly flag sockets using non-blocking connects() when in SYN SENT.
- and when in LISTEN, we should use the socket's connection queue size.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20631 a95241bf-73f2-0310-859d-f6bbb57e9c96
- ipv4_bind() was broken when binding to addresses not INADDR_ANY, as it wasn't copying the address to the socket, fixed.
- fixed a small issue in TCP's BindToEphemeral where the correct address might not have been bound to the socket.
- some assorted TCP wait lists fixes.
- fixed TCP's Connect() over the loopback interface, we might already be ESTABLISHED after _SendQueue() returns.
- fixed the amount of time we wait in TCP's Accept().
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20629 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Moved FIN handling to after Segment Text handling, it matches the RFC and fixes a possible issue with a user missing some final segment data when receiving a FIN.
- Fixed the FIN handling to better terminate connections (no more senseless chatter in the end with RSTs etc).
- When Bind()ing, set the socket address so a call to getsockname() gets the allocated port correctly.
- After reaching the ESTABLISHED state, try to wake all pending threads (still needs work).
- Corrected the maximum amount of time we wait in SendData() to respect socket->send.timeout.
- Now ReadData() behaves correctly in all possible states.
- There was a missing handling of MSG_DONTWAIT, fixed.
- Better internal handling of PSH.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20624 a95241bf-73f2-0310-859d-f6bbb57e9c96
- modified LinkProtocol::ReadData() a bit so it can safely react to external changes such as the device being monitored going down.
- fixed an issue in invalidate_routes() where in some cases the default route was being kept.
- fixed another issue related with the fifo implementation, the notifier semaphore was being created with count of 1, instead of 0.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20622 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Unfortunely this requires RX lock to become a recursive lock.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20621 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Introduced public net_device_monitor.
- Changed the link protocol to maintain a lock per instance instead of inside the FIFO. Now all of the link instance data is protected.
- Adapted the link protocol to use net_device_monitor.
- Introduced a private Fifo class which doesn't maintain it's own lock.
- Maybe we should add something like a public net_protocol_implementation which maintains a fifo and a benaphore? With the fifo using the structure's lock instead of maintaining it's own.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20614 a95241bf-73f2-0310-859d-f6bbb57e9c96
- fixed a issue in add_interface_to_domain where the device interface's refcount was always incremented since that function was getting the device interface handle and not returning it unconditionlly
- if the ethernet device goes down, and the fd is close()ed, return B_FILE_ERROR instead of calling into the driver again
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20601 a95241bf-73f2-0310-859d-f6bbb57e9c96
- remove all routes that use interfaces going down.
- when a device is going down, remove associated domain interfaces.
- interfaces weren't getting a properly referenced device interface, fixed.
- down call down_device_interface when deleting a interface, instead set it down and let the upcounts do its job.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20600 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Also fixed the buffer size check in UDP's SendData() since UDP's length field includes the size of the header we need to check that as well. IPv4 is correct since we check for the size after prepending the header (due to it being possibly already included).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20592 a95241bf-73f2-0310-859d-f6bbb57e9c96
- don't set_to_empty_address, instead consider NULL to be the empty address and use is_empty_address().
- most ipv4 address module calls already consider NULL to be the empty address, ipv4_hash_address_pair didn't, fixed.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20589 a95241bf-73f2-0310-859d-f6bbb57e9c96
- changed the link, ipv4 and udp modules to use fifo_socket_enqueue_buffer
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20587 a95241bf-73f2-0310-859d-f6bbb57e9c96
- changed the socket module to use thew new RECEIVE/SEND in all forms of recv() and send()
- changed libnetwork to use the new RECEIVE/SEND
- remove transfer_args processing from strace since the structure was removed
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20581 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Moved TIME_WAIT and CLOSED handling to common Receive() path that does Sequence checking and further tests.
* Moved setting FLAG_NO_RECEIVE to the end of Receive() when FIN is set so we can check for NO_RECEIVE before processing the segment text just after processing FIN.
* Added a new action DELETE to be used when in TIME_WAIT and we receive a good RST
