  7. ++ New features:
  8. 2011-03-27: Simon Goldschmidt
  9. * tcp_impl.h, tcp_in.c, tcp_out.c: Removed 'dataptr' from 'struct tcp_seg' and
  10. calculate it in tcp_zero_window_probe (the only place where it was used).
  11. 2010-11-21: Simon Goldschmidt
  12. * dhcp.c/.h: Added a function to deallocate the struct dhcp from a netif
  13. (fixes bug #31525).
  14. 2010-07-12: Simon Goldschmidt (patch by Stephane Lesage)
  15. * ip.c, udp.c/.h, pbuf.h, sockets.c: task #10495: Added support for
  16. IP_MULTICAST_LOOP at socket- and raw-API level.
  17. 2010-06-16: Simon Goldschmidt
  18. * ip.c: Added an optional define (LWIP_IP_ACCEPT_UDP_PORT) that can allow
  19. link-layer-addressed UDP traffic to be received while a netif is down (just
  20. like DHCP during configuration)
  21. 2010-05-22: Simon Goldschmidt
  22. * many many files: bug #27352: removed packing from ip_addr_t, the packed
  23. version is now only used in protocol headers. Added global storage for
  24. current src/dest IP address while in input functions.
  25. 2010-05-16: Simon Goldschmidt
  26. * def.h: task #10391: Add preprocessor-macros for compile-time htonl
  27. calculation (and use them throughout the stack where applicable)
  28. 2010-05-16: Simon Goldschmidt
  29. * opt.h, memp_std.h, memp.c, ppp_oe.h/.c: PPPoE now uses its own MEMP pool
  30. instead of the heap (moved struct pppoe_softc from ppp_oe.c to ppp_oe.h)
  31. 2010-05-16: Simon Goldschmidt
  32. * opt.h, memp_std.h, dns.h/.c: DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses its own
  33. MEMP pool instead of the heap
  34. 2010-05-13: Simon Goldschmidt
  35. * tcp.c, udp.c: task #6995: Implement SO_REUSEADDR (correctly), added
  36. new option SO_REUSE_RXTOALL to pass received UDP broadcast/multicast
  37. packets to more than one pcb.
  38. 2010-05-02: Simon Goldschmidt
  39. * netbuf.h/.c, sockets.c, api_msg.c: use checksum-on-copy for sending
  40. UDP data for LWIP_NETIF_TX_SINGLE_PBUF==1
  41. 2010-04-30: Simon Goldschmidt
  42. * udp.h/.c, pbuf.h/.c: task #6849: added udp_send(_to/_if) functions that
  43. take a precalculated checksum, added pbuf_fill_chksum() to copy data
  44. into a pbuf and at the same time calculating the checksum for that data
  45. 2010-04-29: Simon Goldschmidt
  46. * ip_addr.h, etharp.h/.c, autoip.c: Create overridable macros for copying
  47. 2-byte-aligned IP addresses and MAC addresses
  48. 2010-04-28: Patch by Bill Auerbach
  49. * ip.c: Inline generating IP checksum to save a function call
  50. 2010-04-14: Simon Goldschmidt
  51. * tcpip.h/.c, timers.c: Added an overridable define to get informed when the
  52. tcpip_thread processes messages or timeouts to implement a watchdog.
  53. 2010-03-28: Simon Goldschmidt
  54. * ip_frag.c: create a new (contiguous) PBUF_RAM for every outgoing
  55. fragment if LWIP_NETIF_TX_SINGLE_PBUF==1
  56. 2010-03-27: Simon Goldschmidt
  57. * etharp.c: Speedup TX by moving code from find_entry to etharp_output/
  58. etharp_query to prevent unnecessary function calls (inspired by
  59. patch #7135).
  60. 2010-03-20: Simon Goldschmidt
  61. * opt.h, tcpip.c/.h: Added an option to disable tcpip_(un)timeout code
  62. since the linker cannot do this automatically to save space.
  63. 2010-03-20: Simon Goldschmidt
  64. * opt.h, etharp.c/.h: Added support for static ARP table entries
  65. 2010-03-14: Simon Goldschmidt
  66. * tcp_impl.h, tcp_out.c, inet_chksum.h/.c: task #6849: Calculate checksum
  67. when creating TCP segments, not when (re-)transmitting them.
  68. 2010-03-07: Simon Goldschmidt
  69. * sockets.c: bug #28775 (select/event_callback: only check select_cb_list
  70. on change) plus use SYS_LIGHTWEIGHT_PROT to protect the select code.
  71. This should speed up receiving data on sockets as the select code in
  72. event_callback is only executed when select is waiting.
  73. 2010-03-06: Simon Goldschmidt
  74. * tcp_out.c: task #7013 (Create option to have all packets delivered to
  75. netif->output in one piece): Always copy to try to create single pbufs
  76. in tcp_write.
  77. 2010-03-06: Simon Goldschmidt
  78. * api.h, api_lib.c, sockets.c: task #10167 (sockets: speed up TCP recv
  79. by not allocating a netbuf): added function netconn_recv_tcp_pbuf()
  80. for tcp netconns to receive pbufs, not netbufs; use that function
  81. for tcp sockets.
  82. 2010-03-05: Jakob Ole Stoklundsen / Simon Goldschmidt
  83. * opt.h, tcp.h, tcp_impl.h, tcp.c, tcp_in.c, tcp_out.c: task #7040:
  84. Work on tcp_enqueue: Don't waste memory when chaining segments,
  85. added option TCP_OVERSIZE to prevent creating many small pbufs when
  86. calling tcp_write with many small blocks of data. Instead, pbufs are
  87. allocated larger than needed and the space is used for later calls to
  88. tcp_write.

  137. 2010-01-31: Simon Goldschmidt
  138. * dhcp.h, dhcp.c: Reworked the code that parses DHCP options: parse
  139. them once instead of parsing for every option. This also removes
  140. the need for mem_malloc from dhcp_recv and makes it possible to
  141. correctly retrieve the BOOTP file.
  142. 2010-01-30: simon Goldschmidt

  174. now only called from tcpip_thread or by explicitly checking them.
  175. (TASK#7235)
  176. 2009-12-27: Simon Goldschmidt
  177. * opt.h, etharp.h/.c, init.c, tcpip.c: Added an additional option

  203. * err.h/.c, sockets.c, api_msg.c: fixed bug #31748 (Calling non-blocking connect

  252. 2010-11-20: Simon Goldschmidt
  253. * dns.c: Fixed bug #31701: Error return value from dns_gethostbyname() does

  413. another bug when LWIP_RAND() returns zero.
  414. 2010-02-04: Simon Goldschmidt
  415. * nearly every file: Use macros defined in ip_addr.h (some of them new)
  416. to work with IP addresses (preparation for bug #27352 - Change ip_addr
  417. from struct to typedef (u32_t) - and better code).
  418. 2010-01-31: Simon Goldschmidt
  419. * netif.c: Don't call the link-callback from netif_set_up/down() since
  420. this invalidly retriggers DHCP.
  421. 2010-01-29: Simon Goldschmidt
  422. * ip_addr.h, inet.h, def.h, inet.c, def.c, more: Cleanly separate the
  423. portability file inet.h and its contents from the stack: moved htonX-
  424. functions to def.h (and the new def.c - they are not ipv4 dependent),
  425. let inet.h depend on ip_addr.h and not the other way round.
  426. This fixes bug #28732.
  427. 2010-01-28: Kieran Mansley
  428. * tcp.c: Ensure ssthresh >= 2*MSS

  431. callback can lead to accessing unallocated memory. As a consequence,
  432. ERR_ABRT means the application has called tcp_abort()!
  433. 2010-01-25: Simon Goldschmidt
  434. * snmp_structs.h, msg_in.c: Partly fixed bug #22070 (MIB_OBJECT_WRITE_ONLY

  436. returned by getnext (though not by get)
  437. 2010-01-24: Simon Goldschmidt
  438. * snmp: Renamed the private mib node from 'private' to 'mib_private' to
  439. not use reserved C/C++ keywords
  440. 2010-01-23: Simon Goldschmidt
  441. * sockets.c: Fixed bug #28716: select() returns 0 after waiting for less

  456. error return value to struct api_msg_msg
  457. 2010-01-17: Simon Goldschmidt
  458. * api.h, api_lib.c, sockets.c: Changed netconn_recv() and netconn_accept()
  459. to return err_t (bugs #27709 and #28087)
  460. 2010-01-14: Simon Goldschmidt
  461. * ...: Use typedef for function prototypes throughout the stack.
  462. 2010-01-13: Simon Goldschmidt

  474. 2010-01-08: Simon Goldschmidt
  475. * dns.c: Copy hostname for DNS_LOCAL_HOSTLIST_IS_DYNAMIC==1 since string
  476. passed to dns_local_addhost() might be volatile
  477. 2010-01-07: Simon Goldschmidt
  478. * timers.c, tcp.h: Call tcp_timer_needed() with NO_SYS==1, too

  730. * raw.c, udp.c, init.c, opt.h, ip.h, sockets.h: bug #26309: Implement the
  731. SO(F)_BROADCAST filter for all API layers. Avoid the unindented reception
  732. of broadcast packets even when this option wasn't set. Port maintainers
  733. which want to enable this filter have to set IP_SOF_BROADCAST=1 in opt.h.
  734. If you want this option also filter broadcast on recv operations, you also
  735. have to set IP_SOF_BROADCAST_RECV=1 in opt.h.
  736. 2009-04-28 Simon Goldschmidt, Jakob Stoklund Olesen

  743. 2009-04-25 Simon Goldschmidt
  744. * memp.c, mem.c, memp.h, mem_std.h: bug #26213 "Problem with memory allocation
  745. when debugging": memp_sizes contained the wrong sizes (including sanity
  746. regions); memp pools for MEM_USE_POOLS were too small
  747. 2009-04-24 Simon Goldschmidt, Frédéric Bernon
  748. * inet.c: patch #6765: Fix a small problem with the last changes (incorrect

  750. end of line)
  751. 2009-04-19 Simon Goldschmidt
  752. * rawapi.txt: Fixed bug #26069: Corrected documentation: if tcp_connect fails,
  753. pcb->err is called, not pcb->connected (with an error code).
  754. 2009-04-19 Simon Goldschmidt
  755. * tcp_out.c: Fixed bug #26236: "TCP options (timestamp) don't work with
  756. no-copy-tcpwrite": deallocate option data, only concat segments with same flags

  816. * opt.h, api_msg.c: added configurable default valud for netconn->recv_bufsize:
  817. RECV_BUFSIZE_DEFAULT (fixes bug #23726: pbuf pool exhaustion on slow recv())
  818. 2009-02-10 Simon Goldschmidt
  819. * tcp.c: fixed bug #25467: Listen backlog is not reset on timeout in SYN_RCVD:
  820. Accepts_pending is decrease on a corresponding listen pcb when a connection
  821. in state SYN_RCVD is close.
  822. 2009-01-28 Jonathan Larmour
  823. * pbuf.c: reclaim pbufs from TCP out-of-sequence segments if we run

  838. 2008-10-02 Jonathan Larmour
  839. * dns.c: Hard-code structure sizes, to avoid issues on some compilers where
  840. padding is included.
  841. 2008-09-30 Jonathan Larmour
  842. * sockets.c (lwip_accept): check addr isn't NULL. If it's valid, do an
  843. assertion check that addrlen isn't NULL.
  844. 2008-09-30 Jonathan Larmour
  845. * tcp.c: Fix bug #24227, wrong error message in tcp_bind.
  846. 2008-08-26 Simon Goldschmidt

  851. tcp_close returns != ERR_OK)
  852. 2008-07-08 Frédéric Bernon
  853. * stats.h: Fix some build bugs introduced with patch #6483 (missing some parameters
  854. in macros, mainly if MEM_STATS=0 and MEMP_STATS=0).
  855. 2008-06-24 Jonathan Larmour
  856. * tcp_in.c: Fix for bug #23693 as suggested by Art R. Ensure cseg is unused
  857. if tcp_seg_copy fails.
  858. 2008-06-17 Simon Goldschmidt
  859. * inet_chksum.c: Checked in some ideas of patch #6460 (loop optimizations)
  860. and created defines for swapping bytes and folding u32 to u16.
  861. 2008-05-30 Kieran Mansley
  862. * tcp_in.c Remove redundant "if" statement, and use real rcv_wnd
  863. rather than rcv_ann_wnd when deciding if packets are in-window.
  864. Contributed by <arasmussen@consultant.datasys.swri.edu>
  865. 2008-05-30 Kieran Mansley

  871. 2008-04-15 Simon Goldschmidt
  872. * dhcp.c: fixed bug #22804: dhcp_stop doesn't clear NETIF_FLAG_DHCP
  873. (flag now cleared)
  874. 2008-03-27 Simon Goldschmidt
  875. * mem.c, tcpip.c, tcpip.h, opt.h: fixed bug #21433 (Calling mem_free/pbuf_free
  876. from interrupt context isn't safe): set LWIP_USE_HEAP_FROM_INTERRUPT to 1
  877. in lwipopts.h or use pbuf_free_callback(p)/mem_free_callback(m) to free pbufs
  878. or heap memory from interrupt context
  879. 2008-03-26 Simon Goldschmidt
  880. * tcp_in.c, tcp.c: fixed bug #22249: division by zero could occur if a remote
  881. host sent a zero mss as TCP option.
  882. (STABLE-1.3.0)
  883. ++ New features:
  884. 2008-03-10 Jonathan Larmour
  885. * inet_chksum.c: Allow choice of one of the sample algorithms to be
  886. made from lwipopts.h. Fix comment on how to override LWIP_CHKSUM.
  887. 2008-01-22 Frédéric Bernon
  888. * tcp.c, tcp_in.c, tcp.h, opt.h: Rename LWIP_CALCULATE_EFF_SEND_MSS in
  889. TCP_CALCULATE_EFF_SEND_MSS to have coherent TCP options names.
  890. 2008-01-14 Frédéric Bernon
  891. * rawapi.txt, api_msg.c, tcp.c, tcp_in.c, tcp.h: changes for task #7675 "Enable
  892. to refuse data on a TCP_EVENT_RECV call". Important, behavior changes for the
  893. tcp_recv callback (see rawapi.txt).
  894. 2008-01-14 Frédéric Bernon, Marc Chaland
  895. * ip.c: Integrate patch #6369" ip_input : checking before realloc".
  896. 2008-01-12 Frédéric Bernon
  897. * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
  898. netconn::sem per netconn::op_completed like suggested for the task #7490
  899. "Add return value to sys_mbox_post".
  900. 2008-01-12 Frédéric Bernon
  901. * api_msg.c, opt.h: replace DEFAULT_RECVMBOX_SIZE per DEFAULT_TCP_RECVMBOX_SIZE,
  902. DEFAULT_UDP_RECVMBOX_SIZE and DEFAULT_RAW_RECVMBOX_SIZE (to optimize queues
  903. sizes), like suggested for the task #7490 "Add return value to sys_mbox_post".
  904. 2008-01-10 Frédéric Bernon
  905. * tcpip.h, tcpip.c: add tcpip_callback_with_block function for the task #7490
  906. "Add return value to sys_mbox_post". tcpip_callback is always defined as
  907. "blocking" ("block" parameter = 1).
  908. 2008-01-10 Frédéric Bernon
  909. * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
  910. netconn::mbox (sys_mbox_t) per netconn::sem (sys_sem_t) for the task #7490
  911. "Add return value to sys_mbox_post".
  912. 2008-01-05 Frédéric Bernon
  913. * sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h, opt.h:
  914. Introduce changes for task #7490 "Add return value to sys_mbox_post" with some
  915. modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which
  916. indicate the number of pointers query by the mailbox. There is three defines
  917. in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the
  918. netconn::acceptmbox. Port maintainers, you can decide to just add this new
  919. parameter in your implementation, but to ignore it to keep the previous behavior.
  920. The new sys_mbox_trypost function return a value to know if the mailbox is
  921. full or if the message is posted. Take a look to sys_arch.txt for more details.
  922. This new function is used in tcpip_input (so, can be called in an interrupt
  923. context since the function is not blocking), and in recv_udp and recv_raw.
  924. 2008-01-04 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
  925. * rawapi.txt, api.h, api_lib.c, api_msg.h, api_msg.c, sockets.c, tcp.h, tcp.c,
  926. tcp_in.c, init.c, opt.h: rename backlog options with TCP_ prefix, limit the
  927. "backlog" parameter in an u8_t, 0 is interpreted as "smallest queue", add
  928. documentation in the rawapi.txt file.
  929. 2007-12-31 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
  930. * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Add TCP persist timer
  931. 2007-12-31 Frédéric Bernon, Luca Ceresoli
  932. * autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP packets
  933. in autoip". The change in etharp_raw could be removed, since all calls to
  934. etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be
  935. wrong in the future.
  936. 2007-12-30 Frédéric Bernon, Tom Evans
  937. * ip.c: Fix bug #21846 "LwIP doesn't appear to perform any IP Source Address
  938. Filtering" reported by Tom Evans.
  939. 2007-12-21 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
  940. * tcp.h, opt.h, api.h, api_msg.h, tcp.c, tcp_in.c, api_lib.c, api_msg.c,
  941. sockets.c, init.c: task #7252: Implement TCP listen backlog: Warning: raw API
  942. applications have to call 'tcp_accepted(pcb)' in their accept callback to
  943. keep accepting new connections.
  944. 2007-12-13 Frédéric Bernon
  945. * api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum dns_result"
  946. by err_t type. Add a new err_t code "ERR_INPROGRESS".
  947. 2007-12-12 Frédéric Bernon
  948. * dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles
  949. are the one which have ram usage.
  950. 2007-12-05 Frédéric Bernon
  951. * netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static
  952. set of variables (=0) or a local one (=1). In this last case, your port should
  953. provide a function "struct hostent* sys_thread_hostent( struct hostent* h)"
  954. which have to do a copy of "h" and return a pointer ont the "per-thread" copy.
  955. 2007-12-03 Simon Goldschmidt
  956. * ip.c: ip_input: check if a packet is for inp first before checking all other
  957. netifs on netif_list (speeds up packet receiving in most cases)
  958. 2007-11-30 Simon Goldschmidt
  959. * udp.c, raw.c: task #7497: Sort lists (pcb, netif, ...) for faster access
  960. UDP: move a (connected) pcb selected for input to the front of the list of
  961. pcbs so that it is found faster next time. Same for RAW pcbs that have eaten
  962. a packet.
  963. 2007-11-28 Simon Goldschmidt
  964. * etharp.c, stats.c, stats.h, opt.h: Introduced ETHARP_STATS
  965. 2007-11-25 Simon Goldschmidt
  966. * dhcp.c: dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy
  967. algorithm.
  968. 2007-11-24 Simon Goldschmidt
  969. * netdb.h, netdb.c, sockets.h/.c: Moved lwip_gethostbyname from sockets.c
  970. to the new file netdb.c; included lwip_getaddrinfo.
  971. 2007-11-21 Simon Goldschmidt
  972. * tcp.h, opt.h, tcp.c, tcp_in.c: implemented calculating the effective send-mss
  973. based on the MTU of the netif used to send. Enabled by default. Disable by
  974. setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21492.
  975. 2007-11-19 Frédéric Bernon
  976. * api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name
  977. received match the name query), implement DNS_USES_STATIC_BUF (the place where
  978. copy dns payload to parse the response), return an error if there is no place
  979. for a new query, and fix some minor problems.
  980. 2007-11-16 Simon Goldschmidt
  981. * new files: ipv4/inet.c, ipv4/inet_chksum.c, ipv6/inet6.c
  982. removed files: core/inet.c, core/inet6.c
  983. Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into
  984. inet and chksum part; changed includes in all lwIP files as appropriate
  985. 2007-11-16 Simon Goldschmidt
  986. * api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential
  987. dns resolver function for netconn api (netconn_gethostbyname) and socket api
  988. (gethostbyname/gethostbyname_r).
  989. 2007-11-15 Jim Pettinato, Frédéric Bernon
  990. * opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name
  991. requests with RAW api interface. Initialization is done in lwip_init() with
  992. build time options. DNS timer is added in tcpip_thread context. DHCP can set
  993. DNS server ip addresses when options are received. You need to set LWIP_DNS=1
  994. in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get
  995. some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo"
  996. list with points to improve.
  997. 2007-11-06 Simon Goldschmidt
  998. * opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly
  999. enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status
  1000. for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.
  1001. 2007-11-06 Simon Goldschmidt
  1002. * api.h, api_msg.h and dependent files: Task #7410: Removed the need to include
  1003. core header files in api.h (ip/tcp/udp/raw.h) to hide the internal
  1004. implementation from netconn api applications.
  1005. 2007-11-03 Frédéric Bernon
  1006. * api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP &
  1007. RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled
  1008. by default). Netconn API users can use the netconn_recv_bufsize macro to access
  1009. it. This is a first release which have to be improve for TCP. Note it used the
  1010. netconn::recv_avail which need to be more "thread-safe" (note there is already
  1011. the problem for FIONREAD with lwip_ioctl/ioctlsocket).
  1012. 2007-11-01 Frédéric Bernon, Marc Chaland
  1013. * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c:
  1014. Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api
  1015. layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api
  1016. layer. This option enable to delayed TCP PUSH flag on multiple "write" calls.
  1017. Note that previous "copy" parameter for "write" APIs is now called "apiflags".
  1018. 2007-10-24 Frédéric Bernon
  1019. * api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than
  1020. TCP_EVENT_xxx macros to get a code more readable. It could also help to remove
  1021. some code (like we have talk in "patch #5919 : Create compile switch to remove
  1022. select code"), but it could be done later.
  1023. 2007-10-08 Simon Goldschmidt
  1024. * many files: Changed initialization: many init functions are not needed any
  1025. more since we now rely on the compiler initializing global and static
  1026. variables to zero!
  1027. 2007-10-06 Simon Goldschmidt
  1028. * ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY
  1029. to enqueue the received pbufs so that multiple packets can be reassembled
  1030. simultaneously and no static reassembly buffer is needed.
  1031. 2007-10-05 Simon Goldschmidt
  1032. * tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so
  1033. all netifs (or ports) can use it.
  1034. 2007-10-05 Frédéric Bernon
  1035. * netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the
  1036. common function to reduce a little bit the footprint (for all functions using
  1037. only the "netif" parameter).
  1038. 2007-10-03 Frédéric Bernon
  1039. * netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down,
  1040. netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce
  1041. a little bit the footprint (for all functions using only the "netif" parameter).
  1042. 2007-09-15 Frédéric Bernon
  1043. * udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF
  1044. option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for
  1045. netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for
  1046. IP_MULTICAST_TTL and IP_MULTICAST_IF.
  1047. 2007-09-10 Frédéric Bernon
  1048. * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles
  1049. even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime()
  1050. each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can
  1051. decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but
  1052. call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime()
  1053. or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
  1054. This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
  1055. snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
  1056. when it's queried (any direct call to "sysuptime" is changed by a call to
  1057. snmp_get_sysuptime).
  1058. 2007-09-09 Frédéric Bernon, Bill Florac
  1059. * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP,
  1060. and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags
  1061. if you want IGMP on an interface. igmp_stop() is now called inside netif_remove().
  1062. igmp_report_groups() is now called inside netif_set_link_up() (need to have
  1063. LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait
  1064. the next query message to receive the matching multicast streams).
  1065. 2007-09-08 Frédéric Bernon
  1066. * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains
  1067. IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change).
  1068. Use this new field to access to common pcb fields (ttl, tos, so_options, etc...).
  1069. Enable to access to these fields with LWIP_TCP=0.
  1070. 2007-09-05 Frédéric Bernon
  1071. * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h,
  1072. ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option
  1073. LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default).
  1074. Be careful, disabling ICMP make your product non-compliant to RFC1122, but
  1075. help to reduce footprint, and to reduce "visibility" on the Internet.
  1076. 2007-09-05 Frédéric Bernon, Bill Florac
  1077. * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list
  1078. for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new
  1079. parameters have to be provided: a task name, and a task stack size. For this
  1080. one, since it's platform dependant, you could define the best one for you in
  1081. your lwipopts.h. For port maintainers, you can just add these new parameters
  1082. in your sys_arch.c file, and but it's not mandatory, use them in your OS
  1083. specific functions.
  1084. 2007-09-05 Frédéric Bernon
  1085. * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings
  1086. inside init.c for task #7142 "Sanity check user-configurable values".
  1087. 2007-09-04 Frédéric Bernon, Bill Florac
  1088. * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by
  1089. memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the
  1090. value). It will avoid potential fragmentation problems, use a counter to know
  1091. how many times a group is used on an netif, and free it when all applications
  1092. leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity
  1093. check if LWIP_IGMP!=0).
  1094. 2007-09-03 Frédéric Bernon
  1095. * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement".
  1096. Initialize igmp_mac_filter to NULL in netif_add (this field should be set in
  1097. the netif's "init" function). Use the "imr_interface" field (for socket layer)
  1098. and/or the "interface" field (for netconn layer), for join/leave operations.
  1099. The igmp_join/leavegroup first parameter change from a netif to an ipaddr.
  1100. This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany).
  1101. 2007-08-30 Frédéric Bernon
  1102. * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions
  1103. from api/api_lib". Now netbuf API is independant of netconn, and can be used
  1104. with other API (application based on raw API, or future "socket2" API). Ports
  1105. maintainers just have to add src/api/netbuf.c in their makefile/projects.
  1106. 2007-08-30 Frédéric Bernon, Jonathan Larmour
  1107. * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check
  1108. user-configurable values".
  1109. 2007-08-29 Frédéric Bernon
  1110. * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start.
  1111. igmp_start is call inside netif_add. Now, igmp initialization is in the same
  1112. spirit than the others modules. Modify some IGMP debug traces.
  1113. 2007-08-29 Frédéric Bernon
  1114. * Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function"
  1115. Add lwip_init function to regroup all modules initializations, and to provide
  1116. a place to add code for task #7142 "Sanity check user-configurable values".
  1117. Ports maintainers should remove direct initializations calls from their code,
  1118. and add init.c in their makefiles. Note that lwip_init() function is called
  1119. inside tcpip_init, but can also be used by raw api users since all calls are
  1120. disabled when matching options are disabled. Also note that their is new options
  1121. in opt.h, you should configure in your lwipopts.h (they are enabled per default).
  1122. 2007-08-26 Marc Boucher
  1123. * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL
  1124. since they can under certain circumstances be called with an invalid conn
  1125. pointer after the connection has been closed (and conn has been freed).
  1126. 2007-08-25 Frédéric Bernon (Artem Migaev's Patch)
  1127. * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up".
  1128. Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set.
  1129. 2007-08-22 Frédéric Bernon
  1130. * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK
  1131. to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release.
  1132. 2007-08-22 Frédéric Bernon
  1133. * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT &
  1134. ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the
  1135. name is tcpip_input (we keep the name of 1.2.0 function).
  1136. 2007-08-17 Jared Grubb
  1137. * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool
  1138. settings into new memp_std.h and optional user file lwippools.h. This adds
  1139. more dynamic mempools, and allows the user to create an arbitrary number of
  1140. mempools for mem_malloc.
  1141. 2007-08-16 Marc Boucher
  1142. * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function;
  1143. otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely
  1144. close the connection.
  1145. 2007-08-16 Marc Boucher
  1146. * sockets.c: lwip_accept(): check netconn_peer() error return.
  1147. 2007-08-16 Marc Boucher
  1148. * mem.c, mem.h: Added mem_calloc().
  1149. 2007-08-16 Marc Boucher
  1150. * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT)
  1151. for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG
  1152. and starving other message types.
  1153. Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API
  1154. 2007-08-16 Marc Boucher
  1155. * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf
  1156. type and flgs (later renamed to flags).
  1157. Use enum pbuf_flag as pbuf_type. Renumber PBUF_FLAG_*.
  1158. Improved lwip_recvfrom(). TCP push now propagated.
  1159. 2007-08-16 Marc Boucher
  1160. * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global
  1161. provided by etharp.
  1162. 2007-08-16 Marc Boucher
  1163. * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h,
  1164. etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c:
  1165. Added PPPoE support and various PPP improvements.
  1166. 2007-07-25 Simon Goldschmidt
  1167. * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial,
  1168. making netbuf_copy_partial use this function.
  1169. 2007-07-25 Simon Goldschmidt
  1170. * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with
  1171. 2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and
  1172. other stacks.
  1173. 2007-07-13 Jared Grubb (integrated by Frédéric Bernon)
  1174. * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add
  1175. a link callback in the netif struct, and functions to handle it. Be carefull
  1176. for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c)
  1177. if you want to be sure to be compatible with future changes...
  1178. 2007-06-30 Frédéric Bernon
  1179. * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.
  1180. 2007-06-21 Simon Goldschmidt
  1181. * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both
  1182. LWIP_AUTOIP =0 and =1 to remove redundant code.
  1183. 2007-06-21 Simon Goldschmidt
  1184. * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option
  1185. MEM_USE_POOLS to use 4 pools with different sized elements instead of a
  1186. heap. This both prevents memory fragmentation and gives a higher speed
  1187. at the cost of more memory consumption. Turned off by default.
  1188. 2007-06-21 Simon Goldschmidt
  1189. * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of
  1190. netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into
  1191. int to be able to send a bigger buffer than 64K with one time (mainly
  1192. used from lwip_send).
  1193. 2007-06-21 Simon Goldschmidt
  1194. * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write
  1195. into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too.
  1196. 2007-06-21 Simon Goldschmidt
  1197. * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in
  1198. netconn_write from api_lib.c to api_msg.c to also prevent multiple context-
  1199. changes on low memory or empty send-buffer.
  1200. 2007-06-18 Simon Goldschmidt
  1201. * etharp.c, etharp.h: Changed etharp to use a defined hardware address length
  1202. of 6 to avoid loading netif->hwaddr_len every time (since this file is only
  1203. used for ethernet and struct eth_addr already had a defined length of 6).
  1204. 2007-06-17 Simon Goldschmidt
  1205. * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets
  1206. to disable UDP checksum generation on transmit.
  1207. 2007-06-13 Frédéric Bernon, Simon Goldschmidt
  1208. * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid
  1209. pointers or parameters, and let the possibility to redefined it in cc.h. Use
  1210. this macro to check "conn" parameter in api_msg.c functions.
  1211. 2007-06-11 Simon Goldschmidt
  1212. * sockets.c, sockets.h: Added UDP lite support for sockets
  1213. 2007-06-10 Simon Goldschmidt
  1214. * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled
  1215. by default) to switch off UDP-Lite support if not needed (reduces udp.c code
  1216. size)
  1217. 2007-06-09 Dominik Spies (integrated by Frédéric Bernon)
  1218. * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h:
  1219. AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and
  1220. LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt
  1221. (see TODO mark in the source code).
  1222. 2007-06-09 Simon Goldschmidt
  1223. * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for
  1224. etharp_output() to match netif->output so etharp_output() can be used
  1225. directly as netif->output to save one function call.
  1226. 2007-06-08 Simon Goldschmidt
  1227. * netif.h, ethernetif.c, slipif.c, loopif.c: Added define
  1228. NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables,
  1229. added initialization of those to ethernetif, slipif and loopif.
  1230. 2007-05-18 Simon Goldschmidt
  1231. * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF
  1232. (defaulting to off for now) that can be set to 0 to send fragmented
  1233. packets by passing PBUF_REFs down the stack.
  1234. 2007-05-23 Frédéric Bernon
  1235. * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP
  1236. connections, such present in patch #5959.
  1237. 2007-05-23 Frédéric Bernon
  1238. * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx
  1239. code in only one part...
  1240. 2007-05-18 Simon Goldschmidt
  1241. * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp
  1242. elements to overflow. This is achieved by adding some bytes before and after
  1243. each pool element (increasing their size, of course), filling them with a
  1244. prominent value and checking them on freeing the element.
  1245. Set it to 2 to also check every element in every pool each time memp_malloc()
  1246. or memp_free() is called (slower but more helpful).
  1247. 2007-05-10 Simon Goldschmidt
  1248. * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for
  1249. PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce
  1250. code size.
  1251. 2007-05-11 Frédéric Bernon
  1252. * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c:
  1253. Include a function pointer instead of a table index in the message to reduce
  1254. footprint. Disable some part of lwip_send and lwip_sendto if some options are
  1255. not set (LWIP_TCP, LWIP_UDP, LWIP_RAW).
  1256. 2007-05-10 Simon Goldschmidt
  1257. * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus
  1258. \ extern "C" {' in all header files. Now you can write your application using
  1259. the lwIP stack in C++ and simply #include the core files. Note I have left
  1260. out the netif/ppp/*h header files for now, since I don't know which files are
  1261. included by applications and which are for internal use only.
  1262. 2007-05-09 Simon Goldschmidt
  1263. * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library
  1264. memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for
  1265. situations where some compilers might inline the copy and save a function
  1266. call. Also replaced all calls to memcpy() with calls to (S)MEMCPY().
  1267. 2007-05-08 Simon Goldschmidt
  1268. * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc())
  1269. to be overriden in case the C-library malloc implementation is not protected
  1270. against concurrent access.
  1271. 2007-05-04 Simon Goldschmidt (Atte Kojo)
  1272. * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending
  1273. multiple packets to the same host.
  1274. 2007-05-04 Frédéric Bernon, Jonathan Larmour
  1275. * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible
  1276. to corrupt remote addr/port connection state". Reduce problems "not enought memory" with
  1277. netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between
  1278. sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function.
  1279. Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct,
  1280. these fields are now renamed "addr" & "port".
  1281. 2007-04-11 Jonathan Larmour
  1282. * sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new
  1283. sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return
  1284. with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro
  1285. by the port in sys_arch.h if desired.
  1286. 2007-04-06 Frédéric Bernon, Simon Goldschmidt
  1287. * opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API
  1288. allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp
  1289. clients, using new functions from netifapi.h. Disable as default (no port change to do).
  1290. 2007-04-05 Frédéric Bernon
  1291. * sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant.
  1292. 2007-04-04 Simon Goldschmidt
  1293. * arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x)
  1294. use this for and architecture-independent form to tell the compiler you intentionally
  1295. are not using this variable. Can be overriden in cc.h.
  1296. 2007-03-28 Frédéric Bernon
  1297. * opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to
  1298. define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded
  1299. string, point on one of your's ethernetif field, or alloc a string you will free yourself).
  1300. It will be used by DHCP to register a client hostname, but can also be use when you call
  1301. snmp_set_sysname.
  1302. 2007-03-28 Frédéric Bernon
  1303. * netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to
  1304. initialize a network interface's flag with. It tell this interface is an ethernet
  1305. device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility
  1306. Support for IPv4" section 4.6) when interface is "up" with netif_set_up().
  1307. 2007-03-26 Frédéric Bernon, Jonathan Larmour
  1308. * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build
  1309. time if you only use PPP or SLIP. The default is enable. Note we don't have to call
  1310. etharp_init in your port's initilization sequence if you use tcpip.c, because this call
  1311. is done in tcpip_init function.
  1312. 2007-03-22 Frédéric Bernon
  1313. * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the
  1314. new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in
  1315. your lwipopts.h. More, unused counters are not defined in the stats structs, and not
  1316. display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined
  1317. but never used. Fix msg_in.c with the correct #if test for a stat display.
  1318. 2007-03-21 Kieran Mansley
  1319. * netif.c, netif.h: Apply patch#4197 with some changes (originator: rireland@hmgsl.com).
  1320. Provides callback on netif up/down state change.
  1321. 2007-03-11 Frédéric Bernon, Mace Gael, Steve Reynolds
  1322. * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, igmp.h, igmp.c,
  1323. ip.c, netif.h, tcpip.c, opt.h:
  1324. New configuration option LWIP_IGMP to enable IGMP processing. Based on only one
  1325. filter per all network interfaces. Declare a new function in netif to enable to
  1326. control the MAC filter (to reduce lwIP traffic processing).
  1327. 2007-03-11 Frédéric Bernon
  1328. * tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can
  1329. be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this
  1330. unless you know what you're doing (default are RFC1122 compliant). Note
  1331. that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds.
  1332. 2007-03-08 Frédéric Bernon
  1333. * tcp.h: Keepalive values can be configured at compile time, but don't change
  1334. this unless you know what you're doing (default are RFC1122 compliant).
  1335. 2007-03-08 Frédéric Bernon
  1336. * sockets.c, api.h, api_lib.c, tcpip.c, sys.h, sys.c, err.c, opt.h:
  1337. Implement LWIP_SO_RCVTIMEO configuration option to enable/disable SO_RCVTIMEO
  1338. on UDP sockets/netconn.
  1339. 2007-03-08 Simon Goldschmidt
  1340. * snmp_msg.h, msg_in.c: SNMP UDP ports can be configured at compile time.
  1341. 2007-03-06 Frédéric Bernon
  1342. * api.h, api_lib.c, sockets.h, sockets.c, tcpip.c, sys.h, sys.c, err.h:
  1343. Implement SO_RCVTIMEO on UDP sockets/netconn.
  1344. 2007-02-28 Kieran Mansley (based on patch from Simon Goldschmidt)
  1345. * api_lib.c, tcpip.c, memp.c, memp.h: make API msg structs allocated
  1346. on the stack and remove the API msg type from memp
  1347. 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
  1348. * sockets.h, sockets.c: Move socket initialization to new
  1349. lwip_socket_init() function.
  1350. NOTE: this changes the API with ports. Ports will have to be
  1351. updated to call lwip_socket_init() now.
  1352. 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
  1353. * api_lib.c: Use memcpy in netbuf_copy_partial.
  1354. ++ Bug fixes:
  1355. 2008-03-17 Frédéric Bernon, Ed Kerekes
  1356. * igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have
  1357. some problems to fill the IP header on some targets, use now the
  1358. ip.h macros to do it).
  1359. 2008-03-13 Frédéric Bernon
  1360. * sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using
  1361. (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a
  1362. TCP connection caused a crash. Note that using (lwip_)recvfrom
  1363. like this is a bit slow and that using (lwip)getpeername is the
  1364. good lwip way to do it (so, using recv is faster on tcp sockets).
  1365. 2008-03-12 Frédéric Bernon, Jonathan Larmour
  1366. * api_msg.c, contrib/apps/ping.c: Fix bug #22530 "api_msg.c's
  1367. recv_raw() does not consume data", and the ping sample (with
  1368. LWIP_SOCKET=1, the code did the wrong supposition that lwip_recvfrom
  1369. returned the IP payload, without the IP header).
  1370. 2008-03-04 Jonathan Larmour
  1371. * mem.c, stats.c, mem.h: apply patch #6414 to avoid compiler errors
  1372. and/or warnings on some systems where mem_size_t and size_t differ.
  1373. * pbuf.c, ppp.c: Fix warnings on some systems with mem_malloc.
  1374. 2008-03-04 Kieran Mansley (contributions by others)
  1375. * Numerous small compiler error/warning fixes from contributions to
  1376. mailing list after 1.3.0 release candidate made.
  1377. 2008-01-25 Cui hengbin (integrated by Frédéric Bernon)
  1378. * dns.c: Fix bug #22108 "DNS problem" caused by unaligned structures.
  1379. 2008-01-15 Kieran Mansley
  1380. * tcp_out.c: BUG20511. Modify persist timer to start when we are
  1381. prevented from sending by a small send window, not just a zero
  1382. send window.
  1383. 2008-01-09 Jonathan Larmour
  1384. * opt.h, ip.c: Rename IP_OPTIONS define to IP_OPTIONS_ALLOWED to avoid
  1385. conflict with Linux system headers.
  1386. 2008-01-06 Jonathan Larmour
  1387. * dhcp.c: fix bug #19927: "DHCP NACK problem" by clearing any existing set IP
  1388. address entirely on receiving a DHCPNAK, and restarting discovery.
  1389. 2007-12-21 Simon Goldschmidt
  1390. * sys.h, api_lib.c, api_msg.c, sockets.c: fix bug #21698: "netconn->recv_avail
  1391. is not protected" by using new macros for interlocked access to modify/test
  1392. netconn->recv_avail.
  1393. 2007-12-20 Kieran Mansley (based on patch from Oleg Tyshev)
  1394. * tcp_in.c: fix bug# 21535 (nrtx not reset correctly in SYN_SENT state)
  1395. 2007-12-20 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
  1396. * tcp.c, tcp_in.c, tcp_out.c, tcp.h: fix bug #20199 (better handling
  1397. of silly window avoidance and prevent lwIP from shrinking the window)
  1398. 2007-12-04 Simon Goldschmidt
  1399. * tcp.c, tcp_in.c: fix bug #21699 (segment leak in ooseq processing when last
  1400. data packet was lost): add assert that all segment lists are empty in
  1401. tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED
  1402. state from LAST_ACK in tcp_process
  1403. 2007-12-02 Simon Goldschmidt
  1404. * sockets.h: fix bug #21654: exclude definition of struct timeval from #ifndef FD_SET
  1405. If including <sys/time.h> for system-struct timeval, LWIP_TIMEVAL_PRIVATE now
  1406. has to be set to 0 in lwipopts.h
  1407. 2007-12-02 Simon Goldschmidt
  1408. * api_msg.c, api_lib.c: fix bug #21656 (recvmbox problem in netconn API): always
  1409. allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen
  1410. netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox.
  1411. This is a fix for thread-safety and allocates all items needed for a netconn
  1412. when the netconn is created.
  1413. 2007-11-30 Simon Goldschmidt
  1414. * udp.c: first attempt to fix bug #21655 (DHCP doesn't work reliably with multiple
  1415. netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed
  1416. to netif->dhcp->pcb only (if that exists) and not to any other pcb for the same
  1417. port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address)
  1418. 2007-11-27 Simon Goldschmidt
  1419. * ip.c: fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by
  1420. letting ip_route only use netifs that are up.
  1421. 2007-11-27 Simon Goldschmidt
  1422. * err.h, api_lib.c, api_msg.c, sockets.c: Changed error handling: ERR_MEM, ERR_BUF
  1423. and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and
  1424. sockets block most operations once they have seen a fatal error.
  1425. 2007-11-27 Simon Goldschmidt
  1426. * udp.h, udp.c, dhcp.c: Implemented new function udp_sendto_if which takes the
  1427. netif to send as an argument (to be able to send on netifs that are down).
  1428. 2007-11-26 Simon Goldschmidt
  1429. * tcp_in.c: Fixed bug #21582: pcb->acked accounting can be wrong when ACKs
  1430. arrive out-of-order
  1431. 2007-11-21 Simon Goldschmidt
  1432. * tcp.h, tcp_out.c, api_msg.c: Fixed bug #20287: tcp_output_nagle sends too early
  1433. Fixed the nagle algorithm; nagle now also works for all raw API applications
  1434. and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY'
  1435. 2007-11-12 Frédéric Bernon
  1436. * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most
  1437. of the netconn_peer and netconn_addr processing is done inside tcpip_thread
  1438. context in do_getaddr.
  1439. 2007-11-10 Simon Goldschmidt
  1440. * etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can
  1441. happen any time). Now the packet simply isn't enqueued when out of memory.
  1442. 2007-11-01 Simon Goldschmidt
  1443. * tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or
  1444. TCP_MSS if that is smaller) as long as no MSS option is received from the
  1445. remote host.
  1446. 2007-11-01 Simon Goldschmidt
  1447. * tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN)
  1448. is now based on TCP_MSS instead of pcb->mss (on passive open now effectively
  1449. sending our configured TCP_MSS instead of the one received).
  1450. 2007-11-01 Simon Goldschmidt
  1451. * tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was
  1452. calculated based on the configured TCP_MSS, not on the MSS option received
  1453. with SYN+ACK.
  1454. 2007-10-09 Simon Goldschmidt
  1455. * udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too
  1456. short and also was generated wrong if checksum coverage != tot_len;
  1457. receive: checksum was calculated wrong if checksum coverage != tot_len
  1458. 2007-10-08 Simon Goldschmidt
  1459. * mem.c: lfree was not updated in mem_realloc!
  1460. 2007-10-07 Frédéric Bernon
  1461. * sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential
  1462. crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT:
  1463. this change cause an API breakage for netconn_addr, since a parameter
  1464. type change. Any compiler should cause an error without any changes in
  1465. yours netconn_peer calls (so, it can't be a "silent change"). It also
  1466. reduce a little bit the footprint for socket layer (lwip_getpeername &
  1467. lwip_getsockname use now a common lwip_getaddrname function since
  1468. netconn_peer & netconn_addr have the same parameters).
  1469. 2007-09-20 Simon Goldschmidt
  1470. * tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state)
  1471. by checking tcp_tw_pcbs also
  1472. 2007-09-19 Simon Goldschmidt
  1473. * icmp.c: Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies)
  1474. 2007-09-15 Mike Kleshov
  1475. * mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used)
  1476. 2007-09-06 Frédéric Bernon
  1477. * several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove
  1478. it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which
  1479. already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h"
  1480. if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h.
  1481. 2007-08-30 Frédéric Bernon
  1482. * igmp.h, igmp.c: Some changes to remove some redundant code, add some traces,
  1483. and fix some coding style.
  1484. 2007-08-28 Frédéric Bernon
  1485. * tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any
  1486. kind of packets. These packets are considered like Ethernet packets (payload
  1487. pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets
  1488. are considered like IP packets (payload pointing to iphdr).
  1489. 2007-08-27 Frédéric Bernon
  1490. * api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error
  1491. problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state
  1492. and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT).
  1493. 2007-08-24 Kieran Mansley
  1494. * inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy
  1495. compiler (Paradigm C++)
  1496. 2007-08-09 Frédéric Bernon, Bill Florac
  1497. * stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement.
  1498. Introduce IGMP_STATS to centralize statistics management.
  1499. 2007-08-09 Frédéric Bernon, Bill Florac
  1500. * udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast
  1501. packet on a udp pcb binded on an netif's IP address, and not on "any".
  1502. 2007-08-09 Frédéric Bernon, Bill Florac
  1503. * igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement.
  1504. This is mainly on using lookup/lookfor, and some coding styles...
  1505. 2007-07-26 Frédéric Bernon (and "thedoctor")
  1506. * igmp.c: Fix bug #20595 to accept IGMPv3 "Query" messages.
  1507. 2007-07-25 Simon Goldschmidt
  1508. * api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if
  1509. tcp_output fails in tcp_close, the code in do_close_internal gets simpler
  1510. (tcp_output is called again later from tcp timers).
  1511. 2007-07-25 Simon Goldschmidt
  1512. * ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old
  1513. copy_from_pbuf, which illegally modified the given pbuf.
  1514. 2007-07-25 Simon Goldschmidt
  1515. * tcp_out.c: tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs:
  1516. changed snd_queuelen++ to snd_queuelen += pbuf_clen(p).
  1517. 2007-07-24 Simon Goldschmidt
  1518. * api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the
  1519. correct state (must be CLOSED).
  1520. 2007-07-13 Thomas Taranowski (commited by Jared Grubb)
  1521. * memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed
  1522. allocation. It now returns NULL.
  1523. 2007-07-13 Frédéric Bernon
  1524. * api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in
  1525. all error cases.
  1526. 2007-07-13 Frédéric Bernon
  1527. * api_msg.c: Fix bug #20315: possible memory leak problem if tcp_listen failed,
  1528. because current code doesn't follow rawapi.txt documentation.
  1529. 2007-07-13 Kieran Mansley
  1530. * src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in
  1531. out of sequence processing of received packets
  1532. 2007-07-03 Simon Goldschmidt
  1533. * nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an
  1534. assumption is made that this pbuf is in one piece (i.e. not chained). These
  1535. assumptions clash with the possibility of converting to fully pool-based
  1536. pbuf implementations, where PBUF_RAM pbufs might be chained.
  1537. 2007-07-03 Simon Goldschmidt
  1538. * api.h, api_lib.c, api_msg.c: Final fix for bug #20021 and some other problems
  1539. when closing tcp netconns: removed conn->sem, less context switches when
  1540. closing, both netconn_close and netconn_delete should safely close tcp
  1541. connections.
  1542. 2007-07-02 Simon Goldschmidt
  1543. * ipv4/ip.h, ipv6/ip.h, opt.h, netif.h, etharp.h, ipv4/ip.c, netif.c, raw.c,
  1544. tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off)
  1545. to cache ARP table indices with each pcb instead of single-entry cache for
  1546. the complete stack.
  1547. 2007-07-02 Simon Goldschmidt
  1548. * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent
  1549. warnings when assigning to smaller types.
  1550. 2007-06-28 Simon Goldschmidt
  1551. * tcp_out.c: Added check to prevent tcp_pcb->snd_queuelen from overflowing.
  1552. 2007-06-28 Simon Goldschmidt
  1553. * tcp.h: Fixed bug #20287: Fixed nagle algorithm (sending was done too early if
  1554. a segment contained chained pbufs)
  1555. 2007-06-28 Frédéric Bernon
  1556. * autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute
  1557. a "pseudo-random" value based on netif's MAC and some autoip fields. It's always
  1558. possible to define this macro in your own lwipopts.h to always use C library's
  1559. rand(). Note that autoip_create_rand_addr doesn't use this macro.
  1560. 2007-06-28 Frédéric Bernon
  1561. * netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option
  1562. LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications
  1563. in api_lib/api_msg (use pointers and not type with table, etc...)
  1564. 2007-06-26 Simon Goldschmidt
  1565. * udp.h: Fixed bug #20259: struct udp_hdr was lacking the packin defines.
  1566. 2007-06-25 Simon Goldschmidt
  1567. * udp.c: Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload
  1568. for udp packets with no matching pcb.
  1569. 2007-06-25 Simon Goldschmidt
  1570. * udp.c: Fixed bug #20220: UDP PCB search in udp_input(): a non-local match
  1571. could get udp input packets if the remote side matched.
  1572. 2007-06-13 Simon Goldschmidt
  1573. * netif.c: Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get
  1574. changed in netif_set_ipaddr if previous netif->ip_addr.addr was 0.
  1575. 2007-06-13 Simon Goldschmidt
  1576. * api_msg.c: pcb_new sets conn->err if protocol is not implemented
  1577. -> netconn_new_..() does not allocate a new connection for unsupported
  1578. protocols.
  1579. 2007-06-13 Frédéric Bernon, Simon Goldschmidt
  1580. * api_lib.c: change return expression in netconn_addr and netconn_peer, because
  1581. conn->err was reset to ERR_OK without any reasons (and error was lost)...
  1582. 2007-06-13 Frédéric Bernon, Matthias Weisser
  1583. * opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename
  1584. MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid
  1585. some macro names collision with some OS macros.
  1586. 2007-06-11 Simon Goldschmidt
  1587. * udp.c: UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0,
  1588. create checksum over the complete packet. On RX, if it's < 8 (and not 0),
  1589. discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both
  1590. UDP & UDP Lite.
  1591. 2007-06-11 Srinivas Gollakota & Oleg Tyshev
  1592. * tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP flags"
  1593. where TCP flags wasn't initialized in tcp_keepalive.
  1594. 2007-06-03 Simon Goldschmidt
  1595. * udp.c: udp_input(): Input pbuf was not freed if pcb had no recv function
  1596. registered, p->payload was modified without modifying p->len if sending
  1597. icmp_dest_unreach() (had no negative effect but was definitively wrong).
  1598. 2007-06-03 Simon Goldschmidt
  1599. * icmp.c: Corrected bug #19937: For responding to an icmp echo request, icmp
  1600. re-used the input pbuf even if that didn't have enough space to include the
  1601. link headers. Now the space is tested and a new pbuf is allocated for the
  1602. echo response packet if the echo request pbuf isn't big enough.
  1603. 2007-06-01 Simon Goldschmidt
  1604. * sockets.c: Checked in patch #5914: Moved sockopt processing into tcpip_thread.
  1605. 2007-05-23 Frédéric Bernon
  1606. * api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only
  1607. allocated by do_listen if success) and netconn_accept errors handling. In
  1608. most of api_lib functions, we replace some errors checkings like "if (conn==NULL)"
  1609. by ASSERT, except for netconn_delete.
  1610. 2007-05-23 Frédéric Bernon
  1611. * api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return
  1612. an error code if it's impossible to fetch a pbuf on a TCP connection (and not
  1613. directly close the recvmbox).
  1614. 2007-05-22 Simon Goldschmidt
  1615. * tcp.c: Fixed bug #1895 (tcp_bind not correct) by introducing a list of
  1616. bound but unconnected (and non-listening) tcp_pcbs.
  1617. 2007-05-22 Frédéric Bernon
  1618. * sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only
  1619. used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of
  1620. sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features
  1621. like "sys_timeout" in their application threads.
  1622. 2007-05-22 Frédéric Bernon
  1623. * api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see
  1624. which parameters are used by which do_xxx function, and to avoid "misusing"
  1625. parameters (patch #5938).
  1626. 2007-05-22 Simon Goldschmidt
  1627. * api_lib.c, api_msg.c, raw.c, api.h, api_msg.h, raw.h: Included patch #5938:
  1628. changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto
  1629. is only 8 bits wide. This affects the api, as there, the protocol was
  1630. u16_t, too.
  1631. 2007-05-18 Simon Goldschmidt
  1632. * memp.c: addition to patch #5913: smaller pointer was returned but
  1633. memp_memory was the same size -> did not save memory.
  1634. 2007-05-16 Simon Goldschmidt
  1635. * loopif.c, slipif.c: Fix bug #19729: free pbuf if netif->input() returns
  1636. != ERR_OK.
  1637. 2007-05-16 Simon Goldschmidt
  1638. * api_msg.c, udp.c: If a udp_pcb has a local_ip set, check if it is the same
  1639. as the one of the netif used for sending to prevent sending from old
  1640. addresses after a netif address gets changed (partly fixes bug #3168).
  1641. 2007-05-16 Frédéric Bernon
  1642. * tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work
  1643. with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in
  1644. tcpip_init) because we have to be sure that network interfaces are already
  1645. added (mac filter is updated only in igmp_init for the moment).
  1646. 2007-05-16 Simon Goldschmidt
  1647. * mem.c, memp.c: Removed semaphores from memp, changed sys_sem_wait calls
  1648. into sys_arch_sem_wait calls to prevent timers from running while waiting
  1649. for the heap. This fixes bug #19167.
  1650. 2007-05-13 Simon Goldschmidt
  1651. * tcp.h, sockets.h, sockets.c: Fixed bug from patch #5865 by moving the defines
  1652. for socket options (lwip_set/-getsockopt) used with level IPPROTO_TCP from
  1653. tcp.h to sockets.h.
  1654. 2007-05-07 Simon Goldschmidt
  1655. * mem.c: Another attempt to fix bug #17922.
  1656. 2007-05-04 Simon Goldschmidt
  1657. * pbuf.c, pbuf.h, etharp.c: Further update to ARP queueing: Changed pbuf_copy()
  1658. implementation so that it can be reused (don't allocate the target
  1659. pbuf inside pbuf_copy()).
  1660. 2007-05-04 Simon Goldschmidt
  1661. * memp.c: checked in patch #5913: in memp_malloc() we can return memp as mem
  1662. to save a little RAM (next pointer of memp is not used while not in pool).
  1663. 2007-05-03 "maq"
  1664. * sockets.c: Fix ioctl FIONREAD when some data remains from last recv.
  1665. (patch #3574).
  1666. 2007-04-23 Simon Goldschmidt
  1667. * loopif.c, loopif.h, opt.h, src/netif/FILES: fix bug #2595: "loopif results
  1668. in NULL reference for incoming TCP packets". Loopif has to be configured
  1669. (using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input()
  1670. (multithreading environments, e.g. netif->input() = tcpip_input()) or
  1671. putting packets on a list that is fed to the stack by calling loopif_poll()
  1672. (single-thread / NO_SYS / polling environment where e.g.
  1673. netif->input() = ip_input).
  1674. 2007-04-17 Jonathan Larmour
  1675. * pbuf.c: Use s32_t in pbuf_realloc(), as an s16_t can't reliably hold
  1676. the difference between two u16_t's.
  1677. * sockets.h: FD_SETSIZE needs to match number of sockets, which is
  1678. MEMP_NUM_NETCONN in sockets.c right now.
  1679. 2007-04-12 Jonathan Larmour
  1680. * icmp.c: Reset IP header TTL in ICMP ECHO responses (bug #19580).
  1681. 2007-04-12 Kieran Mansley
  1682. * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Modify way the retransmission
  1683. timer is reset to fix bug#19434, with help from Oleg Tyshev.
  1684. 2007-04-11 Simon Goldschmidt
  1685. * etharp.c, pbuf.c, pbuf.h: 3rd fix for bug #11400 (arp-queuing): More pbufs than
  1686. previously thought need to be copied (everything but PBUF_ROM!). Cleaned up
  1687. pbuf.c: removed functions no needed any more (by etharp).
  1688. 2007-04-11 Kieran Mansley
  1689. * inet.c, ip_addr.h, sockets.h, sys.h, tcp.h: Apply patch #5745: Fix
  1690. "Constant is long" warnings with 16bit compilers. Contributed by
  1691. avatar@mmlab.cse.yzu.edu.tw
  1692. 2007-04-05 Frédéric Bernon, Jonathan Larmour
  1693. * api_msg.c: Fix bug #16830: "err_tcp() posts to connection mailbox when no pend on
  1694. the mailbox is active". Now, the post is only done during a connect, and do_send,
  1695. do_write and do_join_leave_group don't do anything if a previous error was signaled.
  1696. 2007-04-03 Frédéric Bernon
  1697. * ip.c: Don't set the IP_DF ("Don't fragment") flag in the IP header in IP output
  1698. packets. See patch #5834.
  1699. 2007-03-30 Frédéric Bernon
  1700. * api_msg.c: add a "pcb_new" helper function to avoid redundant code, and to add
  1701. missing pcb allocations checking (in do_bind, and for each raw_new). Fix style.
  1702. 2007-03-30 Frédéric Bernon
  1703. * most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with
  1704. others environment defines (these were too "generic").
  1705. 2007-03-28 Frédéric Bernon
  1706. * api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal pbuf_alloc call
  1707. result and can cause a crash. lwip_send now check netbuf_ref result.
  1708. 2007-03-28 Simon Goldschmidt
  1709. * sockets.c Remove "#include <errno.h>" from sockets.c to avoid multiple
  1710. definition of macros (in errno.h and lwip/arch.h) if LWIP_PROVIDE_ERRNO is
  1711. defined. This is the way it should have been already (looking at
  1712. doc/sys_arch.txt)
  1713. 2007-03-28 Kieran Mansley
  1714. * opt.h Change default PBUF_POOL_BUFSIZE (again) to accomodate default MSS +
  1715. IP and TCP headers *and* physical link headers
  1716. 2007-03-26 Frédéric Bernon (based on patch from Dmitry Potapov)
  1717. * api_lib.c: patch for netconn_write(), fixes a possible race condition which cause
  1718. to send some garbage. It is not a definitive solution, but the patch does solve
  1719. the problem for most cases.
  1720. 2007-03-22 Frédéric Bernon
  1721. * api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used).
  1722. 2007-03-22 Frédéric Bernon
  1723. * api_lib.c: somes resources couldn't be freed if there was errors during
  1724. netconn_new_with_proto_and_callback.
  1725. 2007-03-22 Frédéric Bernon
  1726. * ethernetif.c: update netif->input calls to check return value. In older ports,
  1727. it's a good idea to upgrade them, even if before, there could be another problem
  1728. (access to an uninitialized mailbox).
  1729. 2007-03-21 Simon Goldschmidt
  1730. * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed
  1731. by casting to unsigned).
  1732. 2007-03-21 Frédéric Bernon
  1733. * api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from
  1734. api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a
  1735. dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call.
  1736. Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a
  1737. faster and more reliable communication between api_lib and tcpip.
  1738. 2007-03-21 Frédéric Bernon
  1739. * opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0.
  1740. 2007-03-21 Frédéric Bernon
  1741. * api_msg.c, igmp.c, igmp.h: Fix C++ style comments
  1742. 2007-03-21 Kieran Mansley
  1743. * opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS +
  1744. IP and TCP headers
  1745. 2007-03-21 Kieran Mansley
  1746. * Fix all uses of pbuf_header to check the return value. In some
  1747. cases just assert if it fails as I'm not sure how to fix them, but
  1748. this is no worse than before when they would carry on regardless
  1749. of the failure.
  1750. 2007-03-21 Kieran Mansley
  1751. * sockets.c, igmp.c, igmp.h, memp.h: Fix C++ style comments and
  1752. comment out missing header include in icmp.c
  1753. 2007-03-20 Frédéric Bernon
  1754. * memp.h, stats.c: Fix stats_display function where memp_names table wasn't
  1755. synchronized with memp.h.
  1756. 2007-03-20 Frédéric Bernon
  1757. * tcpip.c: Initialize tcpip's mbox, and verify if initialized in tcpip_input,
  1758. tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init problem with
  1759. network interfaces. Also fix a compiler warning.
  1760. 2007-03-20 Kieran Mansley
  1761. * udp.c: Only try and use pbuf_header() to make space for headers if
  1762. not a ROM or REF pbuf.
  1763. 2007-03-19 Frédéric Bernon
  1764. * api_msg.h, api_msg.c, tcpip.h, tcpip.c: Add return types to tcpip_apimsg()
  1765. and api_msg_post().
  1766. 2007-03-19 Frédéric Bernon
  1767. * Remove unimplemented "memp_realloc" function from memp.h.
  1768. 2007-03-11 Simon Goldschmidt
  1769. * pbuf.c: checked in patch #5796: pbuf_alloc: len field claculation caused
  1770. memory corruption.
  1771. 2007-03-11 Simon Goldschmidt (based on patch from Dmitry Potapov)
  1772. * api_lib.c, sockets.c, api.h, api_msg.h, sockets.h: Fixed bug #19251
  1773. (missing `const' qualifier in socket functions), to get more compatible to
  1774. standard POSIX sockets.
  1775. 2007-03-11 Frédéric Bernon (based on patch from Dmitry Potapov)
  1776. * sockets.c: Add asserts inside bind, connect and sendto to check input
  1777. parameters. Remove excessive set_errno() calls after get_socket(), because
  1778. errno is set inside of get_socket(). Move last sock_set_errno() inside
  1779. lwip_close.
  1780. 2007-03-09 Simon Goldschmidt
  1781. * memp.c: Fixed bug #11400: New etharp queueing introduced bug: memp_memory
  1782. was allocated too small.
  1783. 2007-03-06 Simon Goldschmidt
  1784. * tcpip.c: Initialize dhcp timers in tcpip_thread (if LWIP_DHCP) to protect
  1785. the stack from concurrent access.
  1786. 2007-03-06 Frédéric Bernon, Dmitry Potapov
  1787. * tcpip.c, ip_frag.c, ethernetif.c: Fix some build problems, and a redundancy
  1788. call to "lwip_stats.link.recv++;" in low_level_input() & ethernetif_input().
  1789. 2007-03-06 Simon Goldschmidt
  1790. * ip_frag.c, ip_frag.h: Reduce code size: don't include code in those files
  1791. if IP_FRAG == 0 and IP_REASSEMBLY == 0
  1792. 2007-03-06 Frédéric Bernon, Simon Goldschmidt
  1793. * opt.h, ip_frag.h, tcpip.h, tcpip.c, ethernetif.c: add new configuration
  1794. option named ETHARP_TCPIP_ETHINPUT, which enable the new tcpip_ethinput.
  1795. Allow to do ARP processing for incoming packets inside tcpip_thread
  1796. (protecting ARP layer against concurrent access). You can also disable
  1797. old code using tcp_input with new define ETHARP_TCPIP_INPUT set to 0.
  1798. Older ports have to use tcpip_ethinput.
  1799. 2007-03-06 Simon Goldschmidt (based on patch from Dmitry Potapov)
  1800. * err.h, err.c: fixed compiler warning "initialization dircards qualifiers
  1801. from pointer target type"
  1802. 2007-03-05 Frédéric Bernon
  1803. * opt.h, sockets.h: add new configuration options (LWIP_POSIX_SOCKETS_IO_NAMES,
  1804. ETHARP_TRUST_IP_MAC, review SO_REUSE)
  1805. 2007-03-04 Frédéric Bernon
  1806. * api_msg.c: Remove some compiler warnings : parameter "pcb" was never
  1807. referenced.
  1808. 2007-03-04 Frédéric Bernon
  1809. * api_lib.c: Fix "[patch #5764] api_lib.c cleanup: after patch #5687" (from
  1810. Dmitry Potapov).
  1811. The api_msg struct stay on the stack (not moved to netconn struct).
  1812. 2007-03-04 Simon Goldschmidt (based on patch from Dmitry Potapov)
  1813. * pbuf.c: Fix BUG#19168 - pbuf_free can cause deadlock (if
  1814. SYS_LIGHTWEIGHT_PROT=1 & freeing PBUF_RAM when mem_sem is not available)
  1815. Also fixed cast warning in pbuf_alloc()
  1816. 2007-03-04 Simon Goldschmidt
  1817. * etharp.c, etharp.h, memp.c, memp.h, opt.h: Fix BUG#11400 - don't corrupt
  1818. existing pbuf chain when enqueuing multiple pbufs to a pending ARP request
  1819. 2007-03-03 Frédéric Bernon
  1820. * udp.c: remove obsolete line "static struct udp_pcb *pcb_cache = NULL;"
  1821. It is static, and never used in udp.c except udp_init().
  1822. 2007-03-02 Simon Goldschmidt
  1823. * tcpip.c: Moved call to ip_init(), udp_init() and tcp_init() from
  1824. tcpip_thread() to tcpip_init(). This way, raw API connections can be
  1825. initialized before tcpip_thread is running (e.g. before OS is started)
  1826. 2007-03-02 Frédéric Bernon
  1827. * rawapi.txt: Fix documentation mismatch with etharp.h about etharp_tmr's call
  1828. interval.
  1829. 2007-02-28 Kieran Mansley
  1830. * pbuf.c: Fix BUG#17645 - ensure pbuf payload pointer is not moved
  1831. outside the region of the pbuf by pbuf_header()
  1832. 2007-02-28 Kieran Mansley
  1833. * sockets.c: Fix BUG#19161 - ensure milliseconds timeout is non-zero
  1834. when supplied timeout is also non-zero
  1835. (STABLE-1.2.0)
  1836. 2006-12-05 Leon Woestenberg
  1837. * CHANGELOG: Mention STABLE-1.2.0 release.
  1838. ++ New features:
  1839. 2006-12-01 Christiaan Simons
  1840. * mem.h, opt.h: Added MEM_LIBC_MALLOC option.
  1841. Note this is a workaround. Currently I have no other options left.
  1842. 2006-10-26 Christiaan Simons (accepted patch by Jonathan Larmour)
  1843. * ipv4/ip_frag.c: rename MAX_MTU to IP_FRAG_MAX_MTU and move define
  1844. to include/lwip/opt.h.
  1845. * ipv4/lwip/ip_frag.h: Remove unused IP_REASS_INTERVAL.
  1846. Move IP_REASS_MAXAGE and IP_REASS_BUFSIZE to include/lwip/opt.h.
  1847. * opt.h: Add above new options.
  1848. 2006-08-18 Christiaan Simons

  1861. * snmp/mib2.c added
  1862. * snmp/msg_{in,out}.c added
  1863. * include/lwip/snmp_asn1.h added
  1864. * include/lwip/snmp_msg.h added

  1875. 2006-10-11 Christiaan Simons
  1876. * api_lib.c etharp.c, ip.c, memp.c, stats.c, sys.{c,h} tcp.h:
  1877. Partially accepted patch #5449 for ANSI C compatibility / build fixes.
  1878. * ipv4/lwip/ip.h ipv6/lwip/ip.h: Corrected UDP-Lite protocol
  1879. identifier from 170 to 136 (bug #17574).
  1880. 2006-10-10 Christiaan Simons
  1881. * api_msg.c: Fixed Nagle algorithm as reported by Bob Grice.
  1882. 2006-08-17 Christiaan Simons
  1883. * udp.c: Fixed bug #17200, added check for broadcast
  1884. destinations for PCBs bound to a unicast address.
  1885. 2006-08-07 Christiaan Simons
  1886. * api_msg.c: Flushing TCP output in do_close() (bug #15926).
  1887. 2006-06-27 Christiaan Simons
  1888. * api_msg.c: Applied patch for cold case (bug #11135).
  1889. In accept_function() ensure newconn->callback is always initialized.
  1890. 2006-06-15 Christiaan Simons
  1891. * mem.h: added MEM_SIZE_F alias to fix an ancient cold case (bug #1748),
  1892. facilitate printing of mem_size_t and u16_t statistics.
  1893. 2006-06-14 Christiaan Simons
  1894. * api_msg.c: Applied patch #5146 to handle allocation failures
  1895. in accept() by Kevin Lawson.
  1896. 2006-05-26 Christiaan Simons
  1897. * api_lib.c: Removed conn->sem creation and destruction
  1898. from netconn_write() and added sys_sem_new to netconn_new_*.
  1899. (STABLE-1_1_1)
  1900. 2006-03-03 Christiaan Simons
  1901. * ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap
  1902. access and added pbuf_alloc() return value checks.
  1903. 2006-01-01 Leon Woestenberg <leon.woestenberg@gmx.net>
  1904. * tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is
  1905. now handled by the checksum routine properly.
  1906. 2006-02-27 Leon Woestenberg <leon.woestenberg@gmx.net>
  1907. * pbuf.c: Fix alignment; pbuf_init() would not work unless
  1908. pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.)
  1909. 2005-12-20 Leon Woestenberg <leon.woestenberg@gmx.net>
  1910. * tcp.c: Remove PCBs which stay in LAST_ACK state too long. Patch
  1911. submitted by Mitrani Hiroshi.
  1912. 2005-12-15 Christiaan Simons
  1913. * inet.c: Disabled the added summing routine to preserve code space.
  1914. 2005-12-14 Leon Woestenberg <leon.woestenberg@gmx.net>
  1915. * tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
  1916. Added Curt McDowell's optimized checksumming routine for future
  1917. inclusion. Need to create test case for unaliged, aligned, odd,
  1918. even length combination of cases on various endianess machines.
  1919. 2005-12-09 Christiaan Simons
  1920. * inet.c: Rewrote standard checksum routine in proper portable C.
  1921. 2005-11-25 Christiaan Simons
  1922. * udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
  1923. * *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
  1924. u32_t, s32_t typedefs. This solves most debug word-length assumes.
  1925. 2005-07-17 Leon Woestenberg <leon.woestenberg@gmx.net>
  1926. * inet.c: Fixed unaligned 16-bit access in the standard checksum
  1927. routine by Peter Jolasson.
  1928. * slipif.c: Fixed implementation assumption of single-pbuf datagrams.
  1929. 2005-02-04 Leon Woestenberg <leon.woestenberg@gmx.net>
  1930. * tcp_out.c: Fixed uninitialized 'queue' referenced in memerr branch.
  1931. * tcp_{out|in}.c: Applied patch fixing unaligned access.
  1932. 2005-01-04 Leon Woestenberg <leon.woestenberg@gmx.net>
  1933. * pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement.
  1934. 2005-01-03 Leon Woestenberg <leon.woestenberg@gmx.net>
  1935. * udp.c: UDP pcb->recv() was called even when it was NULL.
  1936. (STABLE-1_1_0)
  1937. 2004-12-28 Leon Woestenberg <leon.woestenberg@gmx.net>
  1938. * etharp.*: Disabled multiple packets on the ARP queue.
  1939. This clashes with TCP queueing.
  1940. 2004-11-28 Leon Woestenberg <leon.woestenberg@gmx.net>
  1941. * etharp.*: Fixed race condition from ARP request to ARP timeout.
  1942. Halved the ARP period, doubled the period counts.
  1943. ETHARP_MAX_PENDING now should be at least 2. This prevents
  1944. the counter from reaching 0 right away (which would allow
  1945. too little time for ARP responses to be received).
  1946. 2004-11-25 Leon Woestenberg <leon.woestenberg@gmx.net>
  1947. * dhcp.c: Decline messages were not multicast but unicast.
  1948. * etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
  1949. Do not try hard to insert arbitrary packet's source address,
  1950. etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
  1951. etharp_query() now always DOES call ETHARP_TRY_HARD so that users
  1952. querying an address will see it appear in the cache (DHCP could
  1953. suffer from this when a server invalidly gave an in-use address.)
  1954. * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
  1955. comparing network addresses (identifiers), not the network masks
  1956. themselves.
  1957. * ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
  1958. IP address actually belongs to the network of the given interface.
  1959. 2004-11-24 Kieran Mansley <kjm25@cam.ac.uk>
  1960. * tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.
  1961. (STABLE-1_1_0-RC1)
  1962. 2004-10-16 Kieran Mansley <kjm25@cam.ac.uk>
  1963. * tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
  1964. even if one is already pending, if the rcv_wnd is above a threshold
  1965. (currently TCP_WND/2). This avoids waiting for a timer to expire to send a
  1966. delayed ACK in order to open the window if the stack is only receiving data.
  1967. 2004-09-12 Kieran Mansley <kjm25@cam.ac.uk>
  1968. * tcp*.*: Retransmit time-out handling improvement by Sam Jansen.
  1969. 2004-08-20 Tony Mountifield <tony@softins.co.uk>
  1970. * etharp.c: Make sure the first pbuf queued on an ARP entry
  1971. is properly ref counted.
  1972. 2004-07-27 Tony Mountifield <tony@softins.co.uk>
  1973. * debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
  1974. warnings about comparison.
  1975. * pbuf.c: Stopped compiler complaining of empty if statement
  1976. when LWIP_DEBUGF() empty. Closed an unclosed comment.
  1977. * tcp.c: Stopped compiler complaining of empty if statement
  1978. when LWIP_DEBUGF() empty.
  1979. * ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
  1980. * inet.c: Added a couple of casts to quiet the compiler.
  1981. No need to test isascii(c) before isdigit(c) or isxdigit(c).
  1982. 2004-07-22 Tony Mountifield <tony@softins.co.uk>
  1983. * inet.c: Made data types consistent in inet_ntoa().
  1984. Added casts for return values of checksum routines, to pacify compiler.
  1985. * ip_frag.c, tcp_out.c, sockets.c, pbuf.c
  1986. Small corrections to some debugging statements, to pacify compiler.
  1987. 2004-07-21 Tony Mountifield <tony@softins.co.uk>
  1988. * etharp.c: Removed spurious semicolon and added missing end-of-comment.
  1989. * ethernetif.c Updated low_level_output() to match prototype for
  1990. netif->linkoutput and changed low_level_input() similarly for consistency.
  1991. * api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
  1992. of raw_recv() in raw.h and so avoid compiler error.
  1993. * sockets.c: Added trivial (int) cast to keep compiler happier.
  1994. * ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.
  1995. (STABLE-1_0_0)
  1996. ++ Changes:
  1997. 2004-07-05 Leon Woestenberg <leon.woestenberg@gmx.net>
  1998. * sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure
  1999. your cc.h file defines this either 1 or 0. If non-defined,
  2000. defaults to 1.
  2001. * .c: Added <string.h> and <errno.h> includes where used.
  2002. * etharp.c: Made some array indices unsigned.
  2003. 2004-06-27 Leon Woestenberg <leon.woestenberg@gmx.net>
  2004. * netif.*: Added netif_set_up()/down().
  2005. * dhcp.c: Changes to restart program flow.
  2006. 2004-05-07 Leon Woestenberg <leon.woestenberg@gmx.net>
  2007. * etharp.c: In find_entry(), instead of a list traversal per candidate, do a
  2008. single-pass lookup for different candidates. Should exploit locality.
  2009. 2004-04-29 Leon Woestenberg <leon.woestenberg@gmx.net>
  2010. * tcp*.c: Cleaned up source comment documentation for Doxygen processing.
  2011. * opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC.
  2012. * etharp.c: update_arp_entry() only adds new ARP entries when adviced to by
  2013. the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option.
  2014. ++ Bug fixes:
  2015. 2004-04-27 Leon Woestenberg <leon.woestenberg@gmx.net>
  2016. * etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution
  2017. suggested by Timmy Brolin. Fix for 32-bit processors that cannot access
  2018. non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix
  2019. is to prefix the 14-bit Ethernet headers with two padding bytes.
  2020. 2004-04-23 Leon Woestenberg <leon.woestenberg@gmx.net>
  2021. * ip_addr.c: Fix in the ip_addr_isbroadcast() check.
  2022. * etharp.c: Fixed the case where the packet that initiates the ARP request
  2023. is not queued, and gets lost. Fixed the case where the packets destination
  2024. address is already known; we now always queue the packet and perform an ARP
  2025. request.
  2026. (STABLE-0_7_0)
  2027. ++ Bug fixes:
  2028. * Fixed TCP bug for SYN_SENT to ESTABLISHED state transition.
  2029. * Fixed TCP bug in dequeueing of FIN from out of order segment queue.
  2030. * Fixed two possible NULL references in rare cases.
  2031. (STABLE-0_6_6)
  2032. ++ Bug fixes:
  2033. * Fixed DHCP which did not include the IP address in DECLINE messages.
  2034. ++ Changes:
  2035. * etharp.c has been hauled over a bit.
  2036. (STABLE-0_6_5)
  2037. ++ Bug fixes:
  2038. * Fixed TCP bug induced by bad window resizing with unidirectional TCP traffic.
  2039. * Packets sent from ARP queue had invalid source hardware address.
  2040. ++ Changes:
  2041. * Pass-by ARP requests do now update the cache.
  2042. ++ New features:
  2043. * No longer dependent on ctype.h.
  2044. * New socket options.
  2045. * Raw IP pcb support.
  2046. (STABLE-0_6_4)
  2047. ++ Bug fixes:
  2048. * Some debug formatters and casts fixed.
  2049. * Numereous fixes in PPP.
  2050. ++ Changes:
  2051. * DEBUGF now is LWIP_DEBUGF
  2052. * pbuf_dechain() has been re-enabled.
  2053. * Mentioned the changed use of CVS branches in README.
  2054. (STABLE-0_6_3)
  2055. ++ Bug fixes:
  2056. * Fixed pool pbuf memory leak in pbuf_alloc().
  2057. Occured if not enough PBUF_POOL pbufs for a packet pbuf chain.
  2058. Reported by Savin Zlobec.
  2059. * PBUF_POOL chains had their tot_len field not set for non-first
  2060. pbufs. Fixed in pbuf_alloc().
  2061. ++ New features:
  2062. * Added PPP stack contributed by Marc Boucher
  2063. ++ Changes:
  2064. * Now drops short packets for ICMP/UDP/TCP protocols. More robust.
  2065. * ARP queueuing now queues the latest packet instead of the first.
  2066. This is the RFC recommended behaviour, but can be overridden in
  2067. lwipopts.h.
  2068. (0.6.2)
  2069. ++ Bugfixes:
  2070. * TCP has been fixed to deal with the new use of the pbuf->ref
  2071. counter.
  2072. * DHCP dhcp_inform() crash bug fixed.
  2073. ++ Changes:
  2074. * Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
  2075. pbuf_refresh(). This has sped up pbuf pool operations considerably.
  2076. Implemented by David Haas.
  2077. (0.6.1)
  2078. ++ New features:
  2079. * The packet buffer implementation has been enhanced to support
  2080. zero-copy and copy-on-demand for packet buffers which have their
  2081. payloads in application-managed memory.
  2082. Implemented by David Haas.
  2083. Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
  2084. if an outgoing packet can be directly sent on the link, or perform
  2085. a copy-on-demand when necessary.
  2086. The application can safely assume the packet is sent, and the RAM
  2087. is available to the application directly after calling udp_send()
  2088. or similar function.
  2089. ++ Bugfixes:
  2090. * ARP_QUEUEING should now correctly work for all cases, including
  2091. PBUF_REF.
  2092. Implemented by Leon Woestenberg.
  2093. ++ Changes:
  2094. * IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
  2095. to a '0.0.0.0' IP address.
  2096. * The packet buffer implementation is changed. The pbuf->ref counter
  2097. meaning has changed, and several pbuf functions have been
  2098. adapted accordingly.
  2099. * netif drivers have to be changed to set the hardware address length field
  2100. that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).
  2101. See the contrib/ports/c16x cs8900 driver as a driver example.
  2102. * netif's have a dhcp field that must be initialized to NULL by the driver.
  2103. See the contrib/ports/c16x cs8900 driver as a driver example.
  2104. (0.5.x) This file has been unmaintained up to 0.6.1. All changes are
  2105. logged in CVS but have not been explained here.
  2106. (0.5.3) Changes since version 0.5.2
  2107. ++ Bugfixes:
  2108. * memp_malloc(MEMP_API_MSG) could fail with multiple application
  2109. threads because it wasn't protected by semaphores.
  2110. ++ Other changes:
  2111. * struct ip_addr now packed.
  2112. * The name of the time variable in arp.c has been changed to ctime
  2113. to avoid conflicts with the time() function.
  2114. (0.5.2) Changes since version 0.5.1
  2115. ++ New features:
  2116. * A new TCP function, tcp_tmr(), now handles both TCP timers.
  2117. ++ Bugfixes:
  2118. * A bug in tcp_parseopt() could cause the stack to hang because of a
  2119. malformed TCP option.
  2120. * The address of new connections in the accept() function in the BSD
  2121. socket library was not handled correctly.
  2122. * pbuf_dechain() did not update the ->tot_len field of the tail.
  2123. * Aborted TCP connections were not handled correctly in all
  2124. situations.
  2125. ++ Other changes:
  2126. * All protocol header structs are now packed.
  2127. * The ->len field in the tcp_seg structure now counts the actual
  2128. amount of data, and does not add one for SYN and FIN segments.
  2129. (0.5.1) Changes since version 0.5.0
  2130. ++ New features:
  2131. * Possible to run as a user process under Linux.
  2132. * Preliminary support for cross platform packed structs.
  2133. * ARP timer now implemented.
  2134. ++ Bugfixes:
  2135. * TCP output queue length was badly initialized when opening
  2136. connections.
  2137. * TCP delayed ACKs were not sent correctly.
  2138. * Explicit initialization of BSS segment variables.
  2139. * read() in BSD socket library could drop data.
  2140. * Problems with memory alignment.
  2141. * Situations when all TCP buffers were used could lead to
  2142. starvation.
  2143. * TCP MSS option wasn't parsed correctly.
  2144. * Problems with UDP checksum calculation.
  2145. * IP multicast address tests had endianess problems.
  2146. * ARP requests had wrong destination hardware address.
  2147. ++ Other changes:
  2148. * struct eth_addr changed from u16_t[3] array to u8_t[6].
  2149. * A ->linkoutput() member was added to struct netif.
  2150. * TCP and UDP ->dest_* struct members where changed to ->remote_*.
  2151. * ntoh* macros are now null definitions for big endian CPUs.
  2152. (0.5.0) Changes since version 0.4.2
  2153. ++ New features:
  2154. * Redesigned operating system emulation layer to make porting easier.
  2155. * Better control over TCP output buffers.
  2156. * Documenation added.
  2157. ++ Bugfixes:
  2158. * Locking issues in buffer management.
  2159. * Bugfixes in the sequential API.
  2160. * IP forwarding could cause memory leakage. This has been fixed.
  2161. ++ Other changes:
  2162. * Directory structure somewhat changed; the core/ tree has been
  2163. collapsed.
  2164. (0.4.2) Changes since version 0.4.1
  2165. ++ New features:
  2166. * Experimental ARP implementation added.
  2167. * Skeleton Ethernet driver added.
  2168. * Experimental BSD socket API library added.
  2169. ++ Bugfixes:
  2170. * In very intense situations, memory leakage could occur. This has
  2171. been fixed.
  2172. ++ Other changes:
  2173. * Variables named "data" and "code" have been renamed in order to
  2174. avoid name conflicts in certain compilers.
  2175. * Variable++ have in appliciable cases been translated to ++variable
  2176. since some compilers generate better code in the latter case.
  2177. (0.4.1) Changes since version 0.4
  2178. ++ New features:
  2179. * TCP: Connection attempts time out earlier than data
  2180. transmissions. Nagle algorithm implemented. Push flag set on the
  2181. last segment in a burst.
  2182. * UDP: experimental support for UDP-Lite extensions.
  2183. ++ Bugfixes:
  2184. * TCP: out of order segments were in some cases handled incorrectly,
  2185. and this has now been fixed. Delayed acknowledgements was broken
  2186. in 0.4, has now been fixed. Binding to an address that is in use
  2187. now results in an error. Reset connections sometimes hung an
  2188. application; this has been fixed.
  2189. * Checksum calculation sometimes failed for chained pbufs with odd
  2190. lengths. This has been fixed.
  2191. * API: a lot of bug fixes in the API. The UDP API has been improved
  2192. and tested. Error reporting and handling has been
  2193. improved. Logical flaws and race conditions for incoming TCP
  2194. connections has been found and removed.
  2195. * Memory manager: alignment issues. Reallocating memory sometimes
  2196. failed, this has been fixed.
  2197. * Generic library: bcopy was flawed and has been fixed.
  2198. ++ Other changes:
  2199. * API: all datatypes has been changed from generic ones such as
  2200. ints, to specified ones such as u16_t. Functions that return
  2201. errors now have the correct type (err_t).
  2202. * General: A lot of code cleaned up and debugging code removed. Many
  2203. portability issues have been fixed.
  2204. * The license was changed; the advertising clause was removed.
  2205. * C64 port added.
  2206. * Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri
  2207. Kosunen, Mikael Caleres, and Frits Wilmink for reporting and
  2208. fixing bugs!
  2209. (0.4) Changes since version 0.3.1
  2210. * Memory management has been radically changed; instead of
  2211. allocating memory from a shared heap, memory for objects that are
  2212. rapidly allocated and deallocated is now kept in pools. Allocation
  2213. and deallocation from those memory pools is very fast. The shared
  2214. heap is still present but is used less frequently.
  2215. * The memory, memory pool, and packet buffer subsystems now support
  2216. 4-, 2-, or 1-byte alignment.
  2217. * "Out of memory" situations are handled in a more robust way.
  2218. * Stack usage has been reduced.
  2219. * Easier configuration of lwIP parameters such as memory usage,
  2220. TTLs, statistics gathering, etc. All configuration parameters are
  2221. now kept in a single header file "lwipopts.h".
  2222. * The directory structure has been changed slightly so that all
  2223. architecture specific files are kept under the src/arch
  2224. hierarchy.
  2225. * Error propagation has been improved, both in the protocol modules
  2226. and in the API.
  2227. * The code for the RTXC architecture has been implemented, tested
  2228. and put to use.
  2229. * Bugs have been found and corrected in the TCP, UDP, IP, API, and
  2230. the Internet checksum modules.
  2231. * Bugs related to porting between a 32-bit and a 16-bit architecture
  2232. have been found and corrected.
  2233. * The license has been changed slightly to conform more with the
  2234. original BSD license, including the advertisement clause.
  2235. (0.3.1) Changes since version 0.3
  2236. * Fix of a fatal bug in the buffer management. Pbufs with allocated
  2237. RAM never returned the RAM when the pbuf was deallocated.
  2238. * TCP congestion control, window updates and retransmissions did not
  2239. work correctly. This has now been fixed.
  2240. * Bugfixes in the API.
  2241. (0.3) Changes since version 0.2
  2242. * New and improved directory structure. All include files are now
  2243. kept in a dedicated include/ directory.
  2244. * The API now has proper error handling. A new function,
  2245. netconn_err(), now returns an error code for the connection in
  2246. case of errors.
  2247. * Improvements in the memory management subsystem. The system now
  2248. keeps a pointer to the lowest free memory block. A new function,
  2249. mem_malloc2() tries to allocate memory once, and if it fails tries
  2250. to free some memory and retry the allocation.
  2251. * Much testing has been done with limited memory
  2252. configurations. lwIP now does a better job when overloaded.
  2253. * Some bugfixes and improvements to the buffer (pbuf) subsystem.
  2254. * Many bugfixes in the TCP code:
  2255. - Fixed a bug in tcp_close().
  2256. - The TCP receive window was incorrectly closed when out of
  2257. sequence segments was received. This has been fixed.
  2258. - Connections are now timed-out of the FIN-WAIT-2 state.
  2259. - The initial congestion window could in some cases be too
  2260. large. This has been fixed.
  2261. - The retransmission queue could in some cases be screwed up. This
  2262. has been fixed.
  2263. - TCP RST flag now handled correctly.
  2264. - Out of sequence data was in some cases never delivered to the
  2265. application. This has been fixed.
  2266. - Retransmitted segments now contain the correct acknowledgment
  2267. number and advertised window.
  2268. - TCP retransmission timeout backoffs are not correctly computed
  2269. (ala BSD). After a number of retransmissions, TCP now gives up
  2270. the connection.
  2271. * TCP connections now are kept on three lists, one for active
  2272. connections, one for listening connections, and one for
  2273. connections that are in TIME-WAIT. This greatly speeds up the fast
  2274. timeout processing for sending delayed ACKs.
  2275. * TCP now provides proper feedback to the application when a
  2276. connection has been successfully set up.
  2277. * More comments have been added to the code. The code has also been
  2278. somewhat cleaned up.
  2279. (0.2) Initial public release.
