lm3s下lwip的udp

  2007-03-30 Fr閐閞ic Bernon
  * most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with
    others environment defines (these were too "generic").

  2007-03-28 Fr閐閞ic Bernon
  * api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal pbuf_alloc call
    result and can cause a crash. lwip_send now check netbuf_ref result.

  2007-03-28 Simon Goldschmidt
  * sockets.c Remove "#include <errno.h>" from sockets.c to avoid multiple
    definition of macros (in errno.h and lwip/arch.h) if LWIP_PROVIDE_ERRNO is
    defined. This is the way it should have been already (looking at
    doc/sys_arch.txt)

  2007-03-28 Kieran Mansley
  * opt.h Change default PBUF_POOL_BUFSIZE (again) to accomodate default MSS +
    IP and TCP headers *and* physical link headers

  2007-03-26 Fr閐閞ic Bernon (based on patch from Dmitry Potapov)
  * api_lib.c: patch for netconn_write(), fixes a possible race condition which cause
    to send some garbage. It is not a definitive solution, but the patch does solve
    the problem for most cases.

  2007-03-22 Fr閐閞ic Bernon
  * api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used).

  2007-03-22 Fr閐閞ic Bernon
  * api_lib.c: somes resources couldn't be freed if there was errors during
    netconn_new_with_proto_and_callback.

  2007-03-22 Fr閐閞ic Bernon
  * ethernetif.c: update netif->input calls to check return value. In older ports,
    it's a good idea to upgrade them, even if before, there could be another problem
    (access to an uninitialized mailbox).

  2007-03-21 Simon Goldschmidt
  * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed
    by casting to unsigned).

  2007-03-21 Fr閐閞ic Bernon
  * api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from
    api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a
    dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call.
    Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a
    faster and more reliable communication between api_lib and tcpip.

  2007-03-21 Fr閐閞ic Bernon
  * opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0.

  2007-03-21 Fr閐閞ic Bernon
  * api_msg.c, igmp.c, igmp.h: Fix C++ style comments

  2007-03-21 Kieran Mansley
  * opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS +
    IP and TCP headers

  2007-03-21 Kieran Mansley
  * Fix all uses of pbuf_header to check the return value.  In some
    cases just assert if it fails as I'm not sure how to fix them, but
    this is no worse than before when they would carry on regardless
    of the failure.

  2007-03-21 Kieran Mansley
  * sockets.c, igmp.c, igmp.h, memp.h: Fix C++ style comments and
    comment out missing header include in icmp.c

  2007-03-20 Fr閐閞ic Bernon
  * memp.h, stats.c: Fix stats_display function where memp_names table wasn't
    synchronized with memp.h.

  2007-03-20 Fr閐閞ic Bernon
  * tcpip.c: Initialize tcpip's mbox, and verify if initialized in tcpip_input,
    tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init problem with 
    network interfaces. Also fix a compiler warning.

  2007-03-20 Kieran Mansley
  * udp.c: Only try and use pbuf_header() to make space for headers if
    not a ROM or REF pbuf.

  2007-03-19 Fr閐閞ic Bernon
  * api_msg.h, api_msg.c, tcpip.h, tcpip.c: Add return types to tcpip_apimsg()
    and api_msg_post().

  2007-03-19 Fr閐閞ic Bernon
  * Remove unimplemented "memp_realloc" function from memp.h.

  2007-03-11 Simon Goldschmidt
  * pbuf.c: checked in patch #5796: pbuf_alloc: len field claculation caused
    memory corruption.

  2007-03-11 Simon Goldschmidt (based on patch from Dmitry Potapov)
  * api_lib.c, sockets.c, api.h, api_msg.h, sockets.h: Fixed bug #19251
    (missing `const' qualifier in socket functions), to get more compatible to
    standard POSIX sockets.

  2007-03-11 Fr閐閞ic Bernon (based on patch from Dmitry Potapov)
  * sockets.c: Add asserts inside bind, connect and sendto to check input
    parameters. Remove excessive set_errno() calls after get_socket(), because
    errno is set inside of get_socket(). Move last sock_set_errno() inside
    lwip_close.

  2007-03-09 Simon Goldschmidt
  * memp.c: Fixed bug #11400: New etharp queueing introduced bug: memp_memory
    was allocated too small.

  2007-03-06 Simon Goldschmidt
  * tcpip.c: Initialize dhcp timers in tcpip_thread (if LWIP_DHCP) to protect
    the stack from concurrent access.

  2007-03-06 Fr閐閞ic Bernon, Dmitry Potapov
  * tcpip.c, ip_frag.c, ethernetif.c: Fix some build problems, and a redundancy
    call to "lwip_stats.link.recv++;" in low_level_input() & ethernetif_input().

  2007-03-06 Simon Goldschmidt
  * ip_frag.c, ip_frag.h: Reduce code size: don't include code in those files
    if IP_FRAG == 0 and IP_REASSEMBLY == 0

  2007-03-06 Fr閐閞ic Bernon, Simon Goldschmidt
  * opt.h, ip_frag.h, tcpip.h, tcpip.c, ethernetif.c: add new configuration
    option named ETHARP_TCPIP_ETHINPUT, which enable the new tcpip_ethinput.
    Allow to do ARP processing for incoming packets inside tcpip_thread
    (protecting ARP layer against concurrent access). You can also disable
    old code using tcp_input with new define ETHARP_TCPIP_INPUT set to 0.
    Older ports have to use tcpip_ethinput.

  2007-03-06 Simon Goldschmidt (based on patch from Dmitry Potapov)
  * err.h, err.c: fixed compiler warning "initialization dircards qualifiers
    from pointer target type"

  2007-03-05 Fr閐閞ic Bernon
  * opt.h, sockets.h: add new configuration options (LWIP_POSIX_SOCKETS_IO_NAMES,
    ETHARP_TRUST_IP_MAC, review SO_REUSE)

  2007-03-04 Fr閐閞ic Bernon
  * api_msg.c: Remove some compiler warnings : parameter "pcb" was never
    referenced.

  2007-03-04 Fr閐閞ic Bernon
  * api_lib.c: Fix "[patch #5764] api_lib.c cleanup: after patch #5687" (from
    Dmitry Potapov).
    The api_msg struct stay on the stack (not moved to netconn struct).

  2007-03-04 Simon Goldschmidt (based on patch from Dmitry Potapov)
  * pbuf.c: Fix BUG#19168 - pbuf_free can cause deadlock (if
    SYS_LIGHTWEIGHT_PROT=1 & freeing PBUF_RAM when mem_sem is not available)
    Also fixed cast warning in pbuf_alloc()

  2007-03-04 Simon Goldschmidt
  * etharp.c, etharp.h, memp.c, memp.h, opt.h: Fix BUG#11400 - don't corrupt
    existing pbuf chain when enqueuing multiple pbufs to a pending ARP request

  2007-03-03 Fr閐閞ic Bernon
  * udp.c: remove obsolete line "static struct udp_pcb *pcb_cache = NULL;"
    It is static, and never used in udp.c except udp_init().

  2007-03-02 Simon Goldschmidt
  * tcpip.c: Moved call to ip_init(), udp_init() and tcp_init() from
    tcpip_thread() to tcpip_init(). This way, raw API connections can be
    initialized before tcpip_thread is running (e.g. before OS is started)

  2007-03-02 Fr閐閞ic Bernon
  * rawapi.txt: Fix documentation mismatch with etharp.h about etharp_tmr's call
    interval.

  2007-02-28 Kieran Mansley 
  * pbuf.c: Fix BUG#17645 - ensure pbuf payload pointer is not moved
    outside the region of the pbuf by pbuf_header()

  2007-02-28 Kieran Mansley 
  * sockets.c: Fix BUG#19161 - ensure milliseconds timeout is non-zero
    when supplied timeout is also non-zero
