freescale k40/k60 freertos-lwip例程

  2007-08-22 Fr閐閞ic Bernon
  * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT &
    ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the 
    name is tcpip_input (we keep the name of 1.2.0 function).

  2007-08-17 Jared Grubb
  * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool 
    settings into new memp_std.h and optional user file lwippools.h. This adds
    more dynamic mempools, and allows the user to create an arbitrary number of
    mempools for mem_malloc.

  2007-08-16 Marc Boucher
  * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function;
    otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely
    close the connection.

  2007-08-16 Marc Boucher
  * sockets.c: lwip_accept(): check netconn_peer() error return.

  2007-08-16 Marc Boucher
  * mem.c, mem.h: Added mem_calloc().

  2007-08-16 Marc Boucher
  * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT)
    for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG
    and starving other message types.
    Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API

  2007-08-16 Marc Boucher
  * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf
    type and flgs (later renamed to flags).
    Use enum pbuf_flag as pbuf_type.  Renumber PBUF_FLAG_*.
    Improved lwip_recvfrom().  TCP push now propagated.

  2007-08-16 Marc Boucher
  * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global
    provided by etharp.

  2007-08-16 Marc Boucher
  * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h,
    etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c:
    Added PPPoE support and various PPP improvements.

  2007-07-25 Simon Goldschmidt
  * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial,
    making netbuf_copy_partial use this function.

  2007-07-25 Simon Goldschmidt
  * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with
    2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and
    other stacks.

  2007-07-13 Jared Grubb (integrated by Fr閐閞ic Bernon)
  * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add
    a link callback in the netif struct, and functions to handle it. Be carefull
    for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c)
    if you want to be sure to be compatible with future changes...

  2007-06-30 Fr閐閞ic Bernon
  * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.

  2007-06-21 Simon Goldschmidt
  * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both
    LWIP_AUTOIP =0 and =1 to remove redundant code.

  2007-06-21 Simon Goldschmidt
  * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option
    MEM_USE_POOLS to use 4 pools with different sized elements instead of a
    heap. This both prevents memory fragmentation and gives a higher speed
    at the cost of more memory consumption. Turned off by default.

  2007-06-21 Simon Goldschmidt
  * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of
    netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into
    int to be able to send a bigger buffer than 64K with one time (mainly
    used from lwip_send).

  2007-06-21 Simon Goldschmidt
  * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write
    into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too.

  2007-06-21 Simon Goldschmidt
  * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in
    netconn_write from api_lib.c to api_msg.c to also prevent multiple context-
    changes on low memory or empty send-buffer.

  2007-06-18 Simon Goldschmidt
  * etharp.c, etharp.h: Changed etharp to use a defined hardware address length
    of 6 to avoid loading netif->hwaddr_len every time (since this file is only
    used for ethernet and struct eth_addr already had a defined length of 6).

  2007-06-17 Simon Goldschmidt
  * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets
    to disable UDP checksum generation on transmit.

  2007-06-13 Fr閐閞ic Bernon, Simon Goldschmidt
  * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid
    pointers or parameters, and let the possibility to redefined it in cc.h. Use
    this macro to check "conn" parameter in api_msg.c functions.

  2007-06-11 Simon Goldschmidt
  * sockets.c, sockets.h: Added UDP lite support for sockets

  2007-06-10 Simon Goldschmidt
  * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled
    by default) to switch off UDP-Lite support if not needed (reduces udp.c code
    size)

  2007-06-09 Dominik Spies (integrated by Fr閐閞ic Bernon)
  * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h:
    AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and
    LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt
    (see TODO mark in the source code).

  2007-06-09 Simon Goldschmidt
  * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for
    etharp_output() to match netif->output so etharp_output() can be used
    directly as netif->output to save one function call.

  2007-06-08 Simon Goldschmidt
  * netif.h, ethernetif.c, slipif.c, loopif.c: Added define
    NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables,
    added initialization of those to ethernetif, slipif and loopif.

  2007-05-18 Simon Goldschmidt
  * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF
    (defaulting to off for now) that can be set to 0 to send fragmented
    packets by passing PBUF_REFs down the stack.

  2007-05-23 Fr閐閞ic Bernon
  * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP
    connections, such present in patch #5959.

  2007-05-23 Fr閐閞ic Bernon
  * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx
    code in only one part...

  2007-05-18 Simon Goldschmidt
  * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp
    elements to overflow. This is achieved by adding some bytes before and after
    each pool element (increasing their size, of course), filling them with a
    prominent value and checking them on freeing the element.
    Set it to 2 to also check every element in every pool each time memp_malloc()
    or memp_free() is called (slower but more helpful).

  2007-05-10 Simon Goldschmidt
  * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for
    PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce
    code size.

  2007-05-11 Fr閐閞ic Bernon
  * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c:
    Include a function pointer instead of a table index in the message to reduce
    footprint. Disable some part of lwip_send and lwip_sendto if some options are
    not set (LWIP_TCP, LWIP_UDP, LWIP_RAW).

  2007-05-10 Simon Goldschmidt
  * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus
    \ extern "C" {' in all header files. Now you can write your application using
    the lwIP stack in C++ and simply #include the core files. Note I have left
    out the netif/ppp/*h header files for now, since I don't know which files are
    included by applications and which are for internal use only.

  2007-05-09 Simon Goldschmidt
  * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library
    memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for
    situations where some compilers might inline the copy and save a function
    call. Also replaced all calls to memcpy() with calls to (S)MEMCPY().

  2007-05-08 Simon Goldschmidt
  * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc())
    to be overriden in case the C-library malloc implementation is not protected
    against concurrent access.

  2007-05-04 Simon Goldschmidt (Atte Kojo)
  * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending
    multiple packets to the same host.

  2007-05-04 Fr閐閞ic Bernon, Jonathan Larmour
  * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible
    to corrupt remote addr/port connection state". Reduce problems "not enought memory" with
    netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between
    sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function.
    Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct,
    these fields are now renamed "addr" & "port".

  2007-04-11 Jonathan Larmour
  * sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new
    sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return
    with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro
    by the port in sys_arch.h if desired.

  2007-04-06 Fr閐閞ic Bernon, Simon Goldschmidt
  * opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API
    allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp
    clients, using new functions from netifapi.h. Disable as default (no port change to do).

  2007-04-05 Fr閐閞ic Bernon
  * sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant.

  2007-04-04 Simon Goldschmidt
  * arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x)
    use this for and architecture-independent form to tell the compiler you intentionally
    are not using this variable. Can be overriden in cc.h.

  2007-03-28 Fr閐閞ic Bernon
  * opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to
    define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded
    string, point on one of your's ethernetif field, or alloc a string you will free yourself).
    It will be used by DHCP to register a client hostname, but can also be use when you call
    snmp_set_sysname.

  2007-03-28 Fr閐閞ic Bernon
  * netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to 
    initialize a network interface's flag with. It tell this interface is an ethernet
    device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility
    Support for IPv4" section 4.6) when interface is "up" with netif_set_up().

  2007-03-26 Fr閐閞ic Bernon, Jonathan Larmour
  * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build
    time if you only use PPP or SLIP. The default is enable. Note we don't have to call 
    etharp_init in your port's initilization sequence if you use tcpip.c, because this call
    is done in tcpip_init function.

  2007-03-22 Fr閐閞ic Bernon
  * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the
    new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in
    your lwipopts.h. More, unused counters are not defined in the stats structs, and not 
    display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined
    but never used. Fix msg_in.c with the correct #if test for a stat display.

  2007-03-21 Kieran Mansley
  * netif.c, netif.h: Apply patch#4197 with some changes (originator: [e-mail]). 
    Provides callback on netif up/down state change.

  2007-03-11 Fr閐閞ic Bernon, Mace Gael, Steve Reynolds
  * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, igmp.h, igmp.c,
    ip.c, netif.h, tcpip.c, opt.h:
    New configuration option LWIP_IGMP to enable IGMP processing. Based on only one 
    filter per all network interfaces. Declare a new function in netif to enable to
    control the MAC filter (to reduce lwIP traffic processing).

  2007-03-11 Fr閐閞ic Bernon
  * tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can
    be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this
    unless you know what you're doing (default are RFC1122 compliant). Note
    that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds.

  2007-03-08 Fr閐閞ic Bernon
  * tcp.h: Keepalive values can be configured at compile time, but don't change
    this unless you know what you're doing (default are RFC1122 compliant).

  2007-03-08 Fr閐閞ic Bernon
  * sockets.c, api.h, api_lib.c, tcpip.c, sys.h, sys.c, err.c, opt.h:
    Implement LWIP_SO_RCVTIMEO configuration option to enable/disable SO_RCVTIMEO
    on UDP sockets/netconn.

  2007-03-08 Simon Goldschmidt
  * snmp_msg.h, msg_in.c: SNMP UDP ports can be configured at compile time.

  2007-03-06 Fr閐閞ic Bernon
  * api.h, api_lib.c, sockets.h, sockets.c, tcpip.c, sys.h, sys.c, err.h: 
    Implement SO_RCVTIMEO on UDP sockets/netconn.

  2007-02-28 Kieran Mansley (based on patch from Simon Goldschmidt)
  * api_lib.c, tcpip.c, memp.c, memp.h: make API msg structs allocated
    on the stack and remove the API msg type from memp

  2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
  * sockets.h, sockets.c: Move socket initialization to new
    lwip_socket_init() function.
    NOTE: this changes the API with ports. Ports will have to be
    updated to call lwip_socket_init() now.

  2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
  * api_lib.c: Use memcpy in netbuf_copy_partial.


  ++ Bug fixes:

  2008-03-17 Fr閐閞ic Bernon, Ed Kerekes
  * igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have
    some problems to fill the IP header on some targets, use now the
    ip.h macros to do it).

  2008-03-13 Fr閐閞ic Bernon
  * sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using
    (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a
