TCP/IP library change log

6.1.0

  • CHANGE: Added a header xtcp_stack.h with defines XTCP_STACK_LWIP or XTCP_STACK_UIP depending on which XTCP stack is being used.
  • CHANGE: Updated the tests and examples to build against the new XTCP library.
  • FIXED: Events are now routed to the correct XTCP interface.
  • FIXED: A possible double-free when closing a connection.
  • Changes to dependencies:
    • lib_random: Added dependency 1.0.0

6.0.1

  • FIXED: The uIP stack now respects a fixed IP configuration.

6.0.0

  • CHANGE: Unified the branches of uIP and lwIP as the backend of the XTCP stack. The default is uIP. To change the stack, define XTCP_STACK in your makefile to be either UIP or LWIP. Then, instead of calling xtcp(...), call either xtcp_uip(...) or xtcp_lwip(...) respectively.
  • CHANGE: The interface between the client and server is now event-driven rather than polling.
  • CHANGE: Channels have been replaced by interfaces as communication medium between client and server.
  • REMOVED: The following xtcp_event_types: XTCP_PUSH_DATA, XTCP_REQUEST_DATA, XTCP_POLL, XTCP_ALREADY_HANDLED
  • CHANGE: The fields of packet_length and client_num have been added to the xtcp_connection_t structure.
  • REMOVED: xtcp_connection_t no longer has a xtcp_connection_type_t field.
  • REMOVED: The ability to pause a connection
  • REMOVED: The ability to partially acknowledge a packet
  • REMOVED: Support for IPv6
  • REMOVED: the ability to send with an index. This functionality is easily replicated with a call to send() with the pointer of the array index location, i.e. &(data[index]).
  • REMOVED: Support for XTCP_EXCLUDE* macros which reduced functionality in order to save code size
  • FIXED: Problem where ethernet packets smaller than 64 bytes would be incorrectly padded with uIP.
  • Changes to dependencies:
    • lib_crypto: Removed dependency

5.1.0

  • ADDED: Support for using lib_wifi to provide the physical transport

5.0.0

  • ADDED: Port of LwIP TCP/IP stack
  • Changes to dependencies:
    • lib_crypto: Added dependency 1.0.0

4.0.3

  • ADDED: Support to enable link status notifications

4.0.2

  • CHANGE: uIP timer.h renamed to uip_timer.h to avoid conflict with xcore timer.h
  • CHANGE: Update to source code license and copyright

4.0.1

  • CHANGE: MAC address parameter to xtcp() is now qualified as const to allow parallel usage
  • RESOLVED: Fixed issue with link up/down events being ignored when SMI is not polled within XTCP

4.0.0

  • CHANGE: Moved over to new file structure
  • CHANGE: Updated to use new lib_ethernet
  • Changes to dependencies:
    • lib_ethernet: Added dependency 3.0.0
    • lib_gpio: Added dependency 1.0.0
    • lib_locks: Added dependency 2.0.0
    • lib_logging: Added dependency 2.0.0
    • lib_otpinfo: Added dependency 2.0.0
    • lib_xassert: Added dependency 2.0.0
