RT-Thread是发展中的下一代微内核嵌入式实时操作系统

  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

(STABLE-1_1_1)

  2006-03-03  Christiaan Simons
  * ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap
    access and added pbuf_alloc() return value checks.

  2006-01-01  Leon Woestenberg <[e-mail]>
  * tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is
    now handled by the checksum routine properly.

  2006-02-27  Leon Woestenberg <[e-mail]>
   * pbuf.c: Fix alignment; pbuf_init() would not work unless
     pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.)

  2005-12-20  Leon Woestenberg <[e-mail]>
  * tcp.c: Remove PCBs which stay in LAST_ACK state too long. Patch
    submitted by Mitrani Hiroshi.

  2005-12-15  Christiaan Simons
  * inet.c: Disabled the added summing routine to preserve code space.

  2005-12-14  Leon Woestenberg <[e-mail]>
  * tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
    Added Curt McDowell's optimized checksumming routine for future
    inclusion. Need to create test case for unaliged, aligned, odd,
    even length combination of cases on various endianess machines.

  2005-12-09  Christiaan Simons
  * inet.c: Rewrote standard checksum routine in proper portable C.

  2005-11-25  Christiaan Simons
  * udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
  * *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
    u32_t, s32_t typedefs. This solves most debug word-length assumes.

  2005-07-17 Leon Woestenberg <[e-mail]>
  * inet.c: Fixed unaligned 16-bit access in the standard checksum
    routine by Peter Jolasson.
  * slipif.c: Fixed implementation assumption of single-pbuf datagrams.

  2005-02-04 Leon Woestenberg <[e-mail]>

  * tcp_{out|in}.c: Applied patch fixing unaligned access.

  2005-01-04 Leon Woestenberg <[e-mail]>
  * pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement.

  2005-01-03 Leon Woestenberg <[e-mail]>
  * udp.c: UDP pcb->recv() was called even when it was NULL.

(STABLE-1_1_0)

  2004-12-28 Leon Woestenberg <[e-mail]>
  * etharp.*: Disabled multiple packets on the ARP queue.
    This clashes with TCP queueing.

  2004-11-28 Leon Woestenberg <[e-mail]>
  * etharp.*: Fixed race condition from ARP request to ARP timeout.
    Halved the ARP period, doubled the period counts.
    ETHARP_MAX_PENDING now should be at least 2. This prevents
    the counter from reaching 0 right away (which would allow
    too little time for ARP responses to be received).

  2004-11-25 Leon Woestenberg <[e-mail]>
  * dhcp.c: Decline messages were not multicast but unicast.
  * etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
    Do not try hard to insert arbitrary packet's source address,
    etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD. 
    etharp_query() now always DOES call ETHARP_TRY_HARD so that users
    querying an address will see it appear in the cache (DHCP could
    suffer from this when a server invalidly gave an in-use address.)
  * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
    comparing network addresses (identifiers), not the network masks
    themselves.
  * ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
    IP address actually belongs to the network of the given interface.

  2004-11-24 Kieran Mansley <[e-mail]>
  * tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.

(STABLE-1_1_0-RC1)

  2004-10-16 Kieran Mansley <[e-mail]>
  * tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
    even if one is already pendi
