Hugo Santos 6e31ae98f9 some object cache / slab improvements. 
- call the reclaimer callback when low on memory.
 - use the depot when on multi-cpu setups (for scalability).
 - fixed the amount of memory spent on slabs for very large objects.

 - 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.

Hugo Santos 624c52d8b7 ARP now queues packets while resolving a destination instead of blocking on send_data(). This fixes several issues: 
- 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.

Hugo Santos fbaad6fdb5 fixed an issue where TCP would RST a connection when a peer trying to connect us re-sent their SYN. 
- 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.

Hugo Santos bfb45f717c introduced a new helper class DatagramSocket which provides a consistent base interface and functionality for the implementation of datagram-based sockets. 
- made the ipv4 raw, udp and link protocols use DatagramSocket.

 2007-04-12 08:22:47 +00:00
Hugo Santos 6c35350908 moved address selection logic to a new 'get_buffer_route'. 
- 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.

 2007-04-11 22:24:12 +00:00
Hugo Santos 87001e059c some NetBufferUtility revamp. 
- 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.

Hugo Santos f73dd74eb9 even more TCP fixage. 
- 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.

Hugo Santos 8107b19403 Fixed some more TCP issues. 
- Properly flag sockets using non-blocking connects() when in SYN SENT.
 - and when in LISTEN, we should use the socket's connection queue size.

Hugo Santos 7664bcb5c4 A couple more TCP fixes. 
- 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().

Hugo Santos a7edede46f fixed multiple TCP issues. 
- 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.

Hugo Santos 9261b12988 packet capture sockets are now properly notified when the device is going down. 
- 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.
