7 ++ New features:
8
9 2012-03-25: Simon Goldschmidt (idea by Mason)
10 * posix/*: added posix-compatibility include files posix/netdb.h and posix/sys/socket.h
11 which are a simple wrapper to the correct lwIP include files.
12
13 2012-01-16: Simon Goldschmidt
14 * opt.h, icmp.c: Added option CHECKSUM_GEN_ICMP
15
16 2011-12-17: Simon Goldschmidt
17 * ip.h: implemented API functions to access so_options of IP pcbs (UDP, TCP, RAW)
18 (fixes bug #35061)
19
20 2011-09-27: Simon Goldschmidt
21 * opt.h, tcp.c, tcp_in.c: Implemented limiting data on ooseq queue (task #9989)
22 (define TCP_OOSEQ_MAX_BYTES / TCP_OOSEQ_MAX_PBUFS in lwipopts.h)
23
24 2011-09-21: Simon Goldschmidt
25 * opt.h, api.h, api_lib.c, api_msg.h/.c, sockets.c: Implemented timeout on
26 send (TCP only, bug #33820)
27
28 2011-09-21: Simon Goldschmidt
29 * init.c: Converted runtime-sanity-checks into compile-time checks that can
30 be disabled (since runtime checks can often not be seen on embedded targets)
31
32 2011-09-11: Simon Goldschmidt
33 * ppp.h, ppp_impl.h: splitted ppp.h to an internal and external header file
34 to get a clear separation of which functions an application or port may use
35 (task #11281)
36
37 2011-09-11: Simon Goldschmidt
38 * opt.h, tcp_impl.h, tcp.c, udp.h/.c: Added a config option to randomize
39 initial local TCP/UDP ports (so that different port ranges are used after
40 a reboot; bug #33818; this one added tcp_init/udp_init functions again)
41
42 2011-09-03: Simon Goldschmidt
43 * dhcp.c: DHCP uses LWIP_RAND() for xid's (bug #30302)
44
45 2011-08-24: Simon Goldschmidt
46 * opt.h, netif.h/.c: added netif remove callback (bug #32397)
47
48 2011-07-26: Simon Goldschmidt
49 * etharp.c: ETHARP_SUPPORT_VLAN: add support for an external VLAN filter
50 function instead of only checking for one VLAN (define ETHARP_VLAN_CHECK_FN)
51
52 2011-07-21: Simon Goldschmidt (patch by hanhui)
53 * ip4.c, etharp.c, pbuf.h: bug #33634 ip_forward() have a faulty behaviour:
54 Added pbuf flags to mark incoming packets as link-layer broadcast/multicast.
55 Also added code to allow ip_forward() to forward non-broadcast packets to
56 the input netif (set IP_FORWARD_ALLOW_TX_ON_RX_NETIF==1).
57
58 2011-07-21: Simon Goldschmidt
59 * sockets.c, opt.h: (bug #30185): added LWIP_FIONREAD_LINUXMODE that makes
60 ioctl/FIONREAD return the size of the next pending datagram.
61
62 2011-06-26: Simon Goldschmidt (patch by Cameron Gutman)
63 * tcp.c, tcp_out.c: bug #33604: added some more asserts to check that
64 pcb->state != LISTEN
65
66 2011-05-25: Simon Goldschmidt
67 * again nearly the whole stack, renamed ip.c to ip4.c, ip_addr.c to ip4_addr.c,
68 combined ipv4/ipv6 inet_chksum.c, added ip.h, ip_addr.h: Combined IPv4
69 and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP
70 code so that the code is more readable.
71
72 2011-05-17: Patch by Ivan Delamer (only checked in by Simon Goldschmidt)
73 * nearly the whole stack: Finally, we got decent IPv6 support, big thanks to
74 Ivan! (this is work in progress: we're just post release anyway :-)
75
76 2011-05-14: Simon Goldschmidt (patch by St?phane Lesage)

376
377 2010-06-16: Simon Goldschmidt

379 link-layer-addressed UDP traffic to be received while a netif is down (just
380 like DHCP during configuration)
381
382 2010-05-22: Simon Goldschmidt
383 * many many files: bug #27352: removed packing from ip_addr_t, the packed

394
395 2010-05-16: Simon Goldschmidt
396 * opt.h, memp_std.h, dns.h/.c: DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses its own

407
408 2010-04-30: Simon Goldschmidt

410 take a precalculated checksum, added pbuf_fill_chksum() to copy data
411 into a pbuf and at the same time calculating the checksum for that data
412
413 2010-04-29: Simon Goldschmidt

425 * ip_frag.c: create a new (contiguous) PBUF_RAM for every outgoing
426 fragment if LWIP_NETIF_TX_SINGLE_PBUF==1
427
428 2010-03-27: Simon Goldschmidt
429 * etharp.c: Speedup TX by moving code from find_entry to etharp_output/
430 etharp_query to prevent unnecessary function calls (inspired by
431 patch #7135).
432
433 2010-03-20: Simon Goldschmidt
434 * opt.h, tcpip.c/.h: Added an option to disable tcpip_(un)timeout code
435 since the linker cannot do this automatically to save space.
436
437 2010-03-20: Simon Goldschmidt
438 * opt.h, etharp.c/.h: Added support for static ARP table entries
439
440 2010-03-14: Simon Goldschmidt
441 * tcp_impl.h, tcp_out.c, inet_chksum.h/.c: task #6849: Calculate checksum
442 when creating TCP segments, not when (re-)transmitting them.
443
444 2010-03-07: Simon Goldschmidt
445 * sockets.c: bug #28775 (select/event_callback: only check select_cb_list
446 on change) plus use SYS_LIGHTWEIGHT_PROT to protect the select code.
447 This should speed up receiving data on sockets as the select code in
448 event_callback is only executed when select is waiting.
449
450 2010-03-06: Simon Goldschmidt
451 * tcp_out.c: task #7013 (Create option to have all packets delivered to
452 netif->output in one piece): Always copy to try to create single pbufs
453 in tcp_write.
454
455 2010-03-06: Simon Goldschmidt
456 * api.h, api_lib.c, sockets.c: task #10167 (sockets: speed up TCP recv
457 by not allocating a netbuf): added function netconn_recv_tcp_pbuf()
458 for tcp netconns to receive pbufs, not netbufs; use that function
459 for tcp sockets.
460
461 2010-03-05: Jakob Ole Stoklundsen / Simon Goldschmidt
462 * opt.h, tcp.h, tcp_impl.h, tcp.c, tcp_in.c, tcp_out.c: task #7040:
463 Work on tcp_enqueue: Don't waste memory when chaining segments,
464 added option TCP_OVERSIZE to prevent creating many small pbufs when
465 calling tcp_write with many small blocks of data. Instead, pbufs are
466 allocated larger than needed and the space is used for later calls to
467 tcp_write.
468
469 2010-02-21: Simon Goldschmidt
470 * stats.c/.h: Added const char* name to mem- and memp-stats for easier
471 debugging.
472
473 2010-02-21: Simon Goldschmidt
474 * tcp.h (and usages), added tcp_impl.h: Splitted API and internal
475 implementation of tcp to make API usage cleare to application programmers
476
477 2010-02-14: Simon Goldschmidt/Stephane Lesage
478 * ip_addr.h: Improved some defines working on ip addresses, added faster
479 macro to copy addresses that cannot be NULL
480
481 2010-02-13: Simon Goldschmidt
482 * api.h, api_lib.c, api_msg.c, sockets.c: task #7865 (implement non-
483 blocking send operation)
484
485 2010-02-12: Simon Goldschmidt
486 * sockets.c/.h: Added a minimal version of posix fctl() to have a
487 standardised way to set O_NONBLOCK for nonblocking sockets.
488
489 2010-02-12: Simon Goldschmidt
490 * dhcp.c/.h, autoip.c/.h: task #10139 (Prefer statically allocated
491 memory): added autoip_set_struct() and dhcp_set_struct() to let autoip
492 and dhcp work with user-allocated structs instead of callin mem_malloc
493
494 2010-02-12: Simon Goldschmidt/Jeff Barber
495 * tcp.c/h: patch #6865 (SO_REUSEADDR for TCP): if pcb.so_options has
496 SOF_REUSEADDR set, allow binding to endpoint in TIME_WAIT
497
498 2010-02-12: Simon Goldschmidt
499 * sys layer: task #10139 (Prefer statically allocated memory): converted
500 mbox and semaphore functions to take pointers to sys_mbox_t/sys_sem_t;
501 converted sys_mbox_new/sys_sem_new to take pointers and return err_t;
502 task #7212: Add Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX
503 to let sys.h use binary semaphores instead of mutexes - as before)
504
505 2010-02-09: Simon Goldschmidt (Simon Kallweit)
506 * timers.c/.h: Added function sys_restart_timeouts() from patch #7085
507 (Restart system timeout handling)
508
509 2010-02-09: Simon Goldschmidt
510 * netif.c/.h, removed loopif.c/.h: task #10153 (Integrate loopif into
511 netif.c) - loopif does not have to be created by the port any more,
512 just define LWIP_HAVE_LOOPIF to 1.
513
514 2010-02-08: Simon Goldschmidt
515 * inet.h, ip_addr.c/.h: Added reentrant versions of inet_ntoa/ipaddr_ntoa
516 inet_ntoa_r/ipaddr_ntoa_r
517
518 2010-02-08: Simon Goldschmidt
519 * netif.h: Added netif_s/get_igmp_mac_filter() macros
520
521 2010-02-05: Simon Goldschmidt
522 * netif.h: Added function-like macros to get/set the hostname on a netif
523
524 2010-02-04: Simon Goldschmidt
525 * nearly every file: Replaced struct ip_addr by typedef ip_addr_t to
526 make changing the actual implementation behind the typedef easier.
527
528 2010-02-01: Simon Goldschmidt
529 * opt.h, memp_std.h, dns.h, netdb.c, memp.c: Let netdb use a memp pool
530 for allocating memory when getaddrinfo() is called.
531
532 2010-01-31: Simon Goldschmidt
533 * dhcp.h, dhcp.c: Reworked the code that parses DHCP options: parse
534 them once instead of parsing for every option. This also removes
535 the need for mem_malloc from dhcp_recv and makes it possible to
536 correctly retrieve the BOOTP file.
537
538 2010-01-30: simon Goldschmidt
539 * sockets.c: Use SYS_LIGHTWEIGHT_PROT instead of a semaphore to protect
540 the sockets array.
541
542 2010-01-29: Simon Goldschmidt (patch by Laura Garrett)
543 * api.h, api_msg.c, sockets.c: Added except set support in select
544 (patch #6860)
545
546 2010-01-29: Simon Goldschmidt (patch by Laura Garrett)
547 * api.h, sockets.h, err.h, api_lib.c, api_msg.c, sockets.c, err.c:
548 Add non-blocking support for connect (partly from patch #6860),
549 plus many cleanups in socket & netconn API.
550
551 2010-01-27: Simon Goldschmidt
552 * opt.h, tcp.h, init.c, api_msg.c: Added TCP_SNDQUEUELOWAT corresponding
553 to TCP_SNDLOWAT and added tcp_sndqueuelen() - this fixes bug #28605
554
555 2010-01-26: Simon Goldschmidt
556 * snmp: Use memp pools for snmp instead of the heap; added 4 new pools.
557
558 2010-01-14: Simon Goldschmidt
559 * ppp.c/.h: Fixed bug #27856: PPP: Set netif link- and status-callback
560 by adding ppp_set_netif_statuscallback()/ppp_set_netif_linkcallback()
561
562 2010-01-13: Simon Goldschmidt
563 * mem.c: The heap now may be moved to user-defined memory by defining
564 LWIP_RAM_HEAP_POINTER as a void pointer to that memory's address
565 (patch #6966 and bug #26133)
566
567 2010-01-10: Simon Goldschmidt (Bill Auerbach)
568 * opt.h, memp.c: patch #6822 (Add option to place memory pools in
569 separate arrays)
570
571 2010-01-10: Simon Goldschmidt
572 * init.c, igmp.c: patch #6463 (IGMP - Adding Random Delay): added define
573 LWIP_RAND() for lwip-wide randomization (to be defined in cc.h)
574
575 2009-12-31: Simon Goldschmidt
576 * tcpip.c, init.c, memp.c, sys.c, memp_std.h, sys.h, tcpip.h
577 added timers.c/.h: Separated timer implementation from semaphore/mbox
578 implementation, moved timer implementation to timers.c/.h, timers are
579 now only called from tcpip_thread or by explicitly checking them.
580 (TASK#7235)
581
582 2009-12-27: Simon Goldschmidt
583 * opt.h, etharp.h/.c, init.c, tcpip.c: Added an additional option
584 LWIP_ETHERNET to support ethernet without ARP (necessary for pure PPPoE)
585
586
587 ++ Bugfixes:

597 * etharp.h/.c: Fixed broken VLAN support.
598
599 2011-03-27: Simon Goldschmidt

601 pcbs) by checking if the pcb was bound (local_port != 0).
602
603 2011-03-27: Simon Goldschmidt

620 * err.h/.c, sockets.c, api_msg.c: fixed bug #31748 (Calling non-blocking connect
621 more than once can render a socket useless) since it mainly involves changing

623
624 2011-03-13: Simon Goldschmidt
625 * sockets.c: fixed bug #32769 (ESHUTDOWN is linux-specific) by fixing

627 use EALRADY instead of -1
628
629 2011-03-13: Simon Goldschmidt
630 * api_lib.c: netconn_accept: return ERR_ABRT instead of ERR_CLSD if the

632 procedure).
633
634 2011-03-13: Simon Goldschmidt
635 * tcp.c: tcp_bind: return ERR_VAL instead of ERR_ISCONN when trying to bind

654
655 2010-11-23: Simon Goldschmidt
656 * etharp.c: Fixed bug #31720: ARP-queueing: RFC 1122 recommends to queue at

668 * etharp.c: Fixed bug #31722: IP packets sent with an AutoIP source addr
669 must be sent link-local
670
671 2010-11-22: Simon Goldschmidt
672 * timers.c: patch #7329: tcp_timer_needed prototype was ifdef'ed out for

684 no-copy TCP writes will never succeed.
685
686 2010-11-20: Simon Goldschmidt
687 * dns.c: Fixed bug #31701: Error return value from dns_gethostbyname() does
688 not match documentation: return ERR_ARG instead of ERR_VAL if not

690
691 2010-10-20: Simon Goldschmidt
692 * sockets.h: Fixed bug #31385: sizeof(struct sockaddr) is 30 but should be 16
693
694 2010-10-05: Simon Goldschmidt

780
781 2010-03-26: Simon Goldschmidt
782 * various files: Fixed compiling with different options disabled (TCP/UDP),

837 * mem.c/.h, pbuf.c: Renamed mem_realloc() to mem_trim() to prevent
838 confusion with realloc()
839

847 admin-status of a netif are up
848
849 2010-02-14: Simon Goldschmidt
850 * opt.h: Disable ETHARP_TRUST_IP_MAC by default since it slows down packet
851 reception and is not really necessary
852
853 2010-02-14: Simon Goldschmidt
854 * etharp.c/.h: Fixed ARP input processing: only add a new entry if a
855 request was directed as us (RFC 826, Packet Reception), otherwise
856 only update existing entries; internalized some functions
857
858 2010-02-14: Simon Goldschmidt
859 * netif.h, etharp.c, tcpip.c: Fixed bug #28183 (ARP and TCP/IP cannot be
860 disabled on netif used for PPPoE) by adding a new netif flag
861 (NETIF_FLAG_ETHERNET) that tells the stack the device is an ethernet
862 device but prevents usage of ARP (so that ethernet_input can be used
863 for PPPoE).
864
865 2010-02-12: Simon Goldschmidt
866 * netif.c: netif_set_link_up/down: only do something if the link state
867 actually changes
868
869 2010-02-12: Simon Goldschmidt/Stephane Lesage
870 * api_msg.c: Fixed bug #28865 (Cannot close socket/netconn in non-blocking
871 connect)
872
873 2010-02-12: Simon Goldschmidt
874 * mem.h: Fixed bug #28866 (mem_realloc function defined in mem.h)
875
876 2010-02-09: Simon Goldschmidt
877 * api_lib.c, api_msg.c, sockets.c, api.h, api_msg.h: Fixed bug #22110
878 (recv() makes receive window update for data that wasn't received by
879 application)
880
881 2010-02-09: Simon Goldschmidt/Stephane Lesage
882 * sockets.c: Fixed bug #28853 (lwip_recvfrom() returns 0 on receive time-out
883 or any netconn_recv() error)
884
885 2010-02-09: Simon Goldschmidt
886 * ppp.c: task #10154 (PPP: Update snmp in/out counters for tx/rx packets)
887
888 2010-02-09: Simon Goldschmidt
889 * netif.c: For loopback packets, adjust the stats- and snmp-counters
890 for the loopback netif.
891
892 2010-02-08: Simon Goldschmidt
893 * igmp.c/.h, ip.h: Moved most defines from igmp.h to igmp.c for clarity
894 since they are not used anywhere else.
895
896 2010-02-08: Simon Goldschmidt (Stéphane Lesage)
897 * igmp.c, igmp.h, stats.c, stats.h: Improved IGMP stats
898 (patch from bug #28798)
899
900 2010-02-08: Simon Goldschmidt (Stéphane Lesage)
901 * igmp.c: Fixed bug #28798 (Error in "Max Response Time" processing) and
902 another bug when LWIP_RAND() returns zero.
903
904 2010-02-04: Simon Goldschmidt
905 * nearly every file: Use macros defined in ip_addr.h (some of them new)
906 to work with IP addresses (preparation for bug #27352 - Change ip_addr
907 from struct to typedef (u32_t) - and better code).
908
909 2010-01-31: Simon Goldschmidt
910 * netif.c: Don't call the link-callback from netif_set_up/down() since
911 this invalidly retriggers DHCP.
912
913 2010-01-29: Simon Goldschmidt
914 * ip_addr.h, inet.h, def.h, inet.c, def.c, more: Cleanly separate the
915 portability file inet.h and its contents from the stack: moved htonX-
916 functions to def.h (and the new def.c - they are not ipv4 dependent),
917 let inet.h depend on ip_addr.h and not the other way round.
918 This fixes bug #28732.
919
920 2010-01-28: Kieran Mansley
921 * tcp.c: Ensure ssthresh >= 2*MSS
922
923 2010-01-27: Simon Goldschmidt
924 * tcp.h, tcp.c, tcp_in.c: Fixed bug #27871: Calling tcp_abort() in recv
925 callback can lead to accessing unallocated memory. As a consequence,
926 ERR_ABRT means the application has called tcp_abort()!
927
928 2010-01-25: Simon Goldschmidt
929 * snmp_structs.h, msg_in.c: Partly fixed bug #22070 (MIB_OBJECT_WRITE_ONLY
930 not implemented in SNMP): write-only or not-accessible are still
931 returned by getnext (though not by get)
932
933 2010-01-24: Simon Goldschmidt
934 * snmp: Renamed the private mib node from 'private' to 'mib_private' to
935 not use reserved C/C++ keywords
936
937 2010-01-23: Simon Goldschmidt
938 * sockets.c: Fixed bug #28716: select() returns 0 after waiting for less
939 than 1 ms
940
941 2010-01-21: Simon Goldschmidt
942 * tcp.c, api_msg.c: Fixed bug #28651 (tcp_connect: no callbacks called
943 if tcp_enqueue fails) both in raw- and netconn-API
944
945 2010-01-19: Simon Goldschmidt
946 * api_msg.c: Fixed bug #27316: netconn: Possible deadlock in err_tcp
947
948 2010-01-18: Iordan Neshev/Simon Goldschmidt
949 * src/netif/ppp: reorganised PPP sourcecode to 2.3.11 including some
950 bugfix backports from 2.4.x.
951
952 2010-01-18: Simon Goldschmidt
953 * mem.c: Fixed bug #28679: mem_realloc calculates mem_stats wrong
954
955 2010-01-17: Simon Goldschmidt
956 * api_lib.c, api_msg.c, (api_msg.h, api.h, sockets.c, tcpip.c):
957 task #10102: "netconn: clean up conn->err threading issues" by adding
958 error return value to struct api_msg_msg
959
960 2010-01-17: Simon Goldschmidt
961 * api.h, api_lib.c, sockets.c: Changed netconn_recv() and netconn_accept()
962 to return err_t (bugs #27709 and #28087)
963
964 2010-01-14: Simon Goldschmidt
965 * ...: Use typedef for function prototypes throughout the stack.
966
967 2010-01-13: Simon Goldschmidt
968 * api_msg.h/.c, api_lib.c: Fixed bug #26672 (close connection when receive
969 window = 0) by correctly draining recvmbox/acceptmbox
970
971 2010-01-11: Simon Goldschmidt
972 * pap.c: Fixed bug #13315 (PPP PAP authentication can result in
973 erroneous callbacks) by copying the code from recent pppd
974
975 2010-01-10: Simon Goldschmidt
976 * raw.c: Fixed bug #28506 (raw_bind should filter received packets)
977
978 2010-01-10: Simon Goldschmidt
979 * tcp.h/.c: bug #28127 (remove call to tcp_output() from tcp_ack(_now)())
980
981 2010-01-08: Simon Goldschmidt
982 * sockets.c: Fixed bug #28519 (lwip_recvfrom bug with len > 65535)
983
984 2010-01-08: Simon Goldschmidt
985 * dns.c: Copy hostname for DNS_LOCAL_HOSTLIST_IS_DYNAMIC==1 since string
986 passed to dns_local_addhost() might be volatile
987
988 2010-01-07: Simon Goldschmidt
989 * timers.c, tcp.h: Call tcp_timer_needed() with NO_SYS==1, too
990
991 2010-01-06: Simon Goldschmidt
992 * netdb.h: Fixed bug #28496: missing include guards in netdb.h
993
994 2009-12-31: Simon Goldschmidt
995 * many ppp files: Reorganised PPP source code from ucip structure to pppd
996 structure to easily compare our code against the pppd code (around v2.3.1)
997
998 2009-12-27: Simon Goldschmidt
999 * tcp_in.c: Another fix for bug #28241 (ooseq processing) and adapted
1000 unit test

1051 tcp_input_pcb until after calling the pcb's callbacks
1052
1053 2009-11-29: Simon Goldschmidt
1054 * tcp_in.c: Fixed bug #28054: Two segments with FIN flag on the out-of-

1056
1057 2009-11-29: Simon Goldschmidt
1058 * pbuf.c: Fixed bug #28064: pbuf_alloc(PBUF_POOL) is not thread-safe by

1060
1061 2009-11-26: Simon Goldschmidt
1062 * tcp.h: Fixed bug #28098: Nagle can prevent fast retransmit from sending
1063 segment
1064
1065 2009-11-26: Simon Goldschmidt
1066 * tcp.h, sockets.c: Fixed bug #28099: API required to disable Nagle
1067 algorithm at PCB level
1068
1069 2009-11-22: Simon Goldschmidt
1070 * tcp_out.c: Fixed bug #27905: FIN isn't combined with data on unsent
1071
1072 2009-11-22: Simon Goldschmidt (suggested by Bill Auerbach)
1073 * tcp.c: tcp_alloc: prevent increasing stats.err for MEMP_TCP_PCB when
1074 reusing time-wait pcb
1075
1076 2009-11-20: Simon Goldschmidt (patch by Albert Bartel)
1077 * sockets.c: Fixed bug #28062: Data received directly after accepting

1086
1087 2009-10-28: Kieran Mansley
1088 * tcp_in.c, tcp_out.c, tcp.h: re-work the fast retransmission code

1110
1111 2009-10-19: Simon Goldschmidt
1112 * dhcp.c/.h: Minor code simplification (don't store received pbuf, change
1113 conditional code to assert where applicable), check pbuf length before
1114 testing for valid reply
1115
1116 2009-10-19: Simon Goldschmidt
1117 * dhcp.c: Removed most calls to udp_connect since they aren't necessary

1119
1120 2009-10-16: Simon Goldschmidt
1121 * ip.c: Fixed bug #27390: Source IP check in ip_input() causes it to drop

1130 timeout
1131
1132 2009-10-15: Simon Goldschmidt

1134 LWIP_AUTOIP_CREATE_SEED_ADDR() returned address in host byte order instead
1135 of network byte order
1136
1137 2009-10-11 Simon Goldschmidt (Jörg Kesten)
1138 * tcp_out.c: Fixed bug #27504: tcp_enqueue wrongly concatenates segments
1139 which are not consecutive when retransmitting unacked segments
1140
1141 2009-10-09 Simon Goldschmidt

1176
1177 2009-05-10 Simon Goldschmidt
1178 * opt.h, sockets.c, pbuf.c, netbuf.h, pbuf.h: task #7013: Added option

1181
1182 2009-05-09 Simon Goldschmidt
1183 * icmp.h, icmp.c: Shrinked ICMP code, added option to NOT check icoming

1185
1186 2009-05-05 Simon Goldschmidt, Jakob Stoklund Olesen
1187 * ip.h, ip.c: Added ip_current_netif() & ip_current_header() to receive

1192
1193 2009-04-25 Simon Goldschmidt
1194 * mem.c, opt.h: Added option MEM_USE_POOLS_TRY_BIGGER_POOL to try the next
1195 bigger malloc pool if one is empty (only usable with MEM_USE_POOLS).
1196
1197 2009-04-21 Simon Goldschmidt
1198 * dns.c, init.c, dns.h, opt.h: task #7507, patch #6786: DNS supports static
1199 hosts table. New configuration options DNS_LOCAL_HOSTLIST and
1200 DNS_LOCAL_HOSTLIST_IS_DYNAMIC. Also, DNS_LOOKUP_LOCAL_EXTERN() can be defined
1201 as an external function for lookup.
1202
1203 2009-04-15 Simon Goldschmidt
1204 * dhcp.c: patch #6763: Global DHCP XID can be redefined to something more unique
1205
1206 2009-03-31 Kieran Mansley
1207 * tcp.c, tcp_out.c, tcp_in.c, sys.h, tcp.h, opts.h: add support for

1209 take option flags rather than specified option data
1210
1211 2009-02-18 Simon Goldschmidt
1212 * cc.h: Added printf formatter for size_t: SZT_F
1213
1214 2009-02-16 Simon Goldschmidt (patch by Rishi Khan)

1220
1221 2009-02-11 Simon Goldschmidt (suggested by Gottfried Spitaler)
1222 * opt.h, memp.h/.c: added MEMP_MEM_MALLOC to use mem_malloc/mem_free instead
1223 of the pool allocator (can save code size with MEM_LIBC_MALLOC if libc-malloc
1224 is otherwise used)
1225
1226 2009-01-28 Jonathan Larmour (suggested by Bill Bauerbach)
1227 * ipv4/inet_chksum.c, ipv4/lwip/inet_chksum.h: inet_chksum_pseudo_partial()
1228 is only used by UDPLITE at present, so conditionalise it.
1229
1230 2008-12-03 Simon Goldschmidt (base on patch from Luca Ceresoli)
1231 * autoip.c: checked in (slightly modified) patch #6683: Customizable AUTOIP
1232 "seed" address. This should reduce AUTOIP conflicts if
1233 LWIP_AUTOIP_CREATE_SEED_ADDR is overridden.
1234
1235 2008-10-02 Jonathan Larmour and Rishi Khan
1236 * sockets.c (lwip_accept): Return EWOULDBLOCK if would block on non-blocking
1237 socket.
1238
1239 2008-06-30 Simon Goldschmidt
1240 * mem.c, opt.h, stats.h: fixed bug #21433: Calling mem_free/pbuf_free from
1241 interrupt context isn't safe: LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT allows
1242 mem_free to run between mem_malloc iterations. Added illegal counter for
1243 mem stats.
1244
1245 2008-06-27 Simon Goldschmidt
1246 * stats.h/.c, some other files: patch #6483: stats module improvement:
1247 Added defines to display each module's statistic individually, added stats
1248 defines for MEM, MEMP and SYS modules, removed (unused) rexmit counter.
1249
1250 2008-06-17 Simon Goldschmidt
1251 * err.h: patch #6459: Made err_t overridable to use a more efficient type

1253
1254 2008-06-17 Simon Goldschmidt
1255 * slipif.c: patch #6480: Added a configuration option for slipif for symmetry

1259 * netif.c, loopif.c, ip.c, netif.h, loopif.h, opt.h: Checked in slightly
1260 modified version of patch # 6370: Moved loopif code to netif.c so that
1261 loopback traffic is supported on all netifs (all local IPs).
1262 Added option to limit loopback packets for each netifs.
1263
1264
1265 ++ Bugfixes:
1266 2009-08-12 Kieran Mansley

1303
1304 2009-05-06 Simon Goldschmidt
1305 * inet_chksum.c: On little endian architectures, use LWIP_PLATFORM_HTONS (if

1335 2009-04-29 Frédéric Bernon
1336 * raw.c, udp.c, init.c, opt.h, ip.h, sockets.h: bug #26309: Implement the
1337 SO(F)_BROADCAST filter for all API layers. Avoid the unindented reception
1338 of broadcast packets even when this option wasn't set. Port maintainers
1339 which want to enable this filter have to set IP_SOF_BROADCAST=1 in opt.h.
1340 If you want this option also filter broadcast on recv operations, you also
1341 have to set IP_SOF_BROADCAST_RECV=1 in opt.h.
1342

1454
1455 2009-02-10 Simon Goldschmidt
1456 * tcp.c: fixed bug #25467: Listen backlog is not reset on timeout in SYN_RCVD:

1458 in state SYN_RCVD is close.
1459
1460 2009-01-28 Jonathan Larmour
1461 * pbuf.c: reclaim pbufs from TCP out-of-sequence segments if we run
1462 out of pool pbufs.
1463
1464 2008-12-19 Simon Goldschmidt

1484 padding is included.
1485
1486 2008-09-30 Jonathan Larmour
1487 * sockets.c (lwip_accept): check addr isn't NULL. If it's valid, do an
1488 assertion check that addrlen isn't NULL.
1489
1490 2008-09-30 Jonathan Larmour
1491 * tcp.c: Fix bug #24227, wrong error message in tcp_bind.
1492

1496
1497 2008-08-14 Simon Goldschmidt
1498 * api_msg.c: fixed bug #23847: do_close_internal references freed memory (when

1500
1501 2008-07-08 Frédéric Bernon
1502 * stats.h: Fix some build bugs introduced with patch #6483 (missing some parameters

1504
1505 2008-06-24 Jonathan Larmour
1506 * tcp_in.c: Fix for bug #23693 as suggested by Art R. Ensure cseg is unused

1511 and created defines for swapping bytes and folding u32 to u16.
1512
1513 2008-05-30 Kieran Mansley
1514 * tcp_in.c Remove redundant "if" statement, and use real rcv_wnd
1515 rather than rcv_ann_wnd when deciding if packets are in-window.
1516 Contributed by <arasmussen@consultant.datasys.swri.edu>
1517
1518 2008-05-30 Kieran Mansley
1519 * mem.h: Fix BUG#23254. Change macro definition of mem_* to allow
1520 passing as function pointers when MEM_LIBC_MALLOC is defined.
1521
1522 2008-05-09 Jonathan Larmour
1523 * err.h, err.c, sockets.c: Fix bug #23119: Reorder timeout error code to

1525
1526 2008-04-15 Simon Goldschmidt
1527 * dhcp.c: fixed bug #22804: dhcp_stop doesn't clear NETIF_FLAG_DHCP
1528 (flag now cleared)
1529
1530 2008-03-27 Simon Goldschmidt
1531 * mem.c, tcpip.c, tcpip.h, opt.h: fixed bug #21433 (Calling mem_free/pbuf_free
1532 from interrupt context isn't safe): set LWIP_USE_HEAP_FROM_INTERRUPT to 1
1533 in lwipopts.h or use pbuf_free_callback(p)/mem_free_callback(m) to free pbufs
1534 or heap memory from interrupt context
1535
1536 2008-03-26 Simon Goldschmidt
1537 * tcp_in.c, tcp.c: fixed bug #22249: division by zero could occur if a remote

1539
1540
1541 (STABLE-1.3.0)
1542
1543 ++ New features:
1544
1545 2008-03-10 Jonathan Larmour
1546 * inet_chksum.c: Allow choice of one of the sample algorithms to be
1547 made from lwipopts.h. Fix comment on how to override LWIP_CHKSUM.
1548
1549 2008-01-22 Frédéric Bernon
1550 * tcp.c, tcp_in.c, tcp.h, opt.h: Rename LWIP_CALCULATE_EFF_SEND_MSS in
1551 TCP_CALCULATE_EFF_SEND_MSS to have coherent TCP options names.
1552
1553 2008-01-14 Frédéric Bernon
1554 * rawapi.txt, api_msg.c, tcp.c, tcp_in.c, tcp.h: changes for task #7675 "Enable
1555 to refuse data on a TCP_EVENT_RECV call". Important, behavior changes for the
1556 tcp_recv callback (see rawapi.txt).
1557
1558 2008-01-14 Frédéric Bernon, Marc Chaland
1559 * ip.c: Integrate patch #6369" ip_input : checking before realloc".
1560
1561 2008-01-12 Frédéric Bernon
1562 * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
1563 netconn::sem per netconn::op_completed like suggested for the task #7490
1564 "Add return value to sys_mbox_post".
1565
1566 2008-01-12 Frédéric Bernon
1567 * api_msg.c, opt.h: replace DEFAULT_RECVMBOX_SIZE per DEFAULT_TCP_RECVMBOX_SIZE,
1568 DEFAULT_UDP_RECVMBOX_SIZE and DEFAULT_RAW_RECVMBOX_SIZE (to optimize queues
1569 sizes), like suggested for the task #7490 "Add return value to sys_mbox_post".
1570
1571 2008-01-10 Frédéric Bernon
1572 * tcpip.h, tcpip.c: add tcpip_callback_with_block function for the task #7490
1573 "Add return value to sys_mbox_post". tcpip_callback is always defined as
1574 "blocking" ("block" parameter = 1).
1575
1576 2008-01-10 Frédéric Bernon
1577 * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
1578 netconn::mbox (sys_mbox_t) per netconn::sem (sys_sem_t) for the task #7490
1579 "Add return value to sys_mbox_post".
1580
1581 2008-01-05 Frédéric Bernon
1582 * sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h, opt.h:
1583 Introduce changes for task #7490 "Add return value to sys_mbox_post" with some
1584 modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which
1585 indicate the number of pointers query by the mailbox. There is three defines
1586 in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the
1587 netconn::acceptmbox. Port maintainers, you can decide to just add this new
1588 parameter in your implementation, but to ignore it to keep the previous behavior.
1589 The new sys_mbox_trypost function return a value to know if the mailbox is
1590 full or if the message is posted. Take a look to sys_arch.txt for more details.
1591 This new function is used in tcpip_input (so, can be called in an interrupt
1592 context since the function is not blocking), and in recv_udp and recv_raw.
1593
1594 2008-01-04 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
1595 * rawapi.txt, api.h, api_lib.c, api_msg.h, api_msg.c, sockets.c, tcp.h, tcp.c,
1596 tcp_in.c, init.c, opt.h: rename backlog options with TCP_ prefix, limit the
1597 "backlog" parameter in an u8_t, 0 is interpreted as "smallest queue", add
1598 documentation in the rawapi.txt file.
1599
1600 2007-12-31 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
1601 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Add TCP persist timer
1602
1603 2007-12-31 Frédéric Bernon, Luca Ceresoli
1604 * autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP packets
1605 in autoip". The change in etharp_raw could be removed, since all calls to
1606 etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be
1607 wrong in the future.
1608
1609 2007-12-30 Frédéric Bernon, Tom Evans
1610 * ip.c: Fix bug #21846 "LwIP doesn't appear to perform any IP Source Address
1611 Filtering" reported by Tom Evans.
1612
1613 2007-12-21 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
1614 * tcp.h, opt.h, api.h, api_msg.h, tcp.c, tcp_in.c, api_lib.c, api_msg.c,
1615 sockets.c, init.c: task #7252: Implement TCP listen backlog: Warning: raw API
1616 applications have to call 'tcp_accepted(pcb)' in their accept callback to
1617 keep accepting new connections.
1618
1619 2007-12-13 Frédéric Bernon
1620 * api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum dns_result"
1621 by err_t type. Add a new err_t code "ERR_INPROGRESS".
1622
1623 2007-12-12 Frédéric Bernon
1624 * dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles
1625 are the one which have ram usage.
1626
1627 2007-12-05 Frédéric Bernon
1628 * netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static
1629 set of variables (=0) or a local one (=1). In this last case, your port should
1630 provide a function "struct hostent* sys_thread_hostent( struct hostent* h)"
1631 which have to do a copy of "h" and return a pointer ont the "per-thread" copy.
1632
1633 2007-12-03 Simon Goldschmidt
1634 * ip.c: ip_input: check if a packet is for inp first before checking all other
1635 netifs on netif_list (speeds up packet receiving in most cases)
1636
1637 2007-11-30 Simon Goldschmidt
1638 * udp.c, raw.c: task #7497: Sort lists (pcb, netif, ...) for faster access
1639 UDP: move a (connected) pcb selected for input to the front of the list of
1640 pcbs so that it is found faster next time. Same for RAW pcbs that have eaten
1641 a packet.
1642
1643 2007-11-28 Simon Goldschmidt
1644 * etharp.c, stats.c, stats.h, opt.h: Introduced ETHARP_STATS
1645
1646 2007-11-25 Simon Goldschmidt
1647 * dhcp.c: dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy
1648 algorithm.
1649
1650 2007-11-24 Simon Goldschmidt
1651 * netdb.h, netdb.c, sockets.h/.c: Moved lwip_gethostbyname from sockets.c
1652 to the new file netdb.c; included lwip_getaddrinfo.
1653
1654 2007-11-21 Simon Goldschmidt
1655 * tcp.h, opt.h, tcp.c, tcp_in.c: implemented calculating the effective send-mss
1656 based on the MTU of the netif used to send. Enabled by default. Disable by
1657 setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21492.
1658
1659 2007-11-19 Frédéric Bernon
1660 * api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name
1661 received match the name query), implement DNS_USES_STATIC_BUF (the place where
1662 copy dns payload to parse the response), return an error if there is no place
1663 for a new query, and fix some minor problems.
1664
1665 2007-11-16 Simon Goldschmidt
1666 * new files: ipv4/inet.c, ipv4/inet_chksum.c, ipv6/inet6.c
1667 removed files: core/inet.c, core/inet6.c
1668 Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into
1669 inet and chksum part; changed includes in all lwIP files as appropriate
1670
1671 2007-11-16 Simon Goldschmidt
1672 * api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential
1673 dns resolver function for netconn api (netconn_gethostbyname) and socket api
1674 (gethostbyname/gethostbyname_r).
1675
1676 2007-11-15 Jim Pettinato, Frédéric Bernon
1677 * opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name
1678 requests with RAW api interface. Initialization is done in lwip_init() with
1679 build time options. DNS timer is added in tcpip_thread context. DHCP can set
1680 DNS server ip addresses when options are received. You need to set LWIP_DNS=1
1681 in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get
1682 some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo"
1683 list with points to improve.
1684
1685 2007-11-06 Simon Goldschmidt
1686 * opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly
1687 enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status
1688 for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.
1689
1690 2007-11-06 Simon Goldschmidt
1691 * api.h, api_msg.h and dependent files: Task #7410: Removed the need to include
1692 core header files in api.h (ip/tcp/udp/raw.h) to hide the internal
1693 implementation from netconn api applications.
1694
1695 2007-11-03 Frédéric Bernon
1696 * api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP &
1697 RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled
1698 by default). Netconn API users can use the netconn_recv_bufsize macro to access
1699 it. This is a first release which have to be improve for TCP. Note it used the
1700 netconn::recv_avail which need to be more "thread-safe" (note there is already
1701 the problem for FIONREAD with lwip_ioctl/ioctlsocket).
1702
1703 2007-11-01 Frédéric Bernon, Marc Chaland
1704 * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c:
1705 Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api
1706 layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api
1707 layer. This option enable to delayed TCP PUSH flag on multiple "write" calls.
1708 Note that previous "copy" parameter for "write" APIs is now called "apiflags".
1709
1710 2007-10-24 Frédéric Bernon
1711 * api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than
1712 TCP_EVENT_xxx macros to get a code more readable. It could also help to remove
1713 some code (like we have talk in "patch #5919 : Create compile switch to remove
1714 select code"), but it could be done later.
1715
1716 2007-10-08 Simon Goldschmidt
1717 * many files: Changed initialization: many init functions are not needed any
1718 more since we now rely on the compiler initializing global and static
1719 variables to zero!
1720
1721 2007-10-06 Simon Goldschmidt
1722 * ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY
1723 to enqueue the received pbufs so that multiple packets can be reassembled
1724 simultaneously and no static reassembly buffer is needed.
1725
1726 2007-10-05 Simon Goldschmidt
1727 * tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so
1728 all netifs (or ports) can use it.
1729
1730 2007-10-05 Frédéric Bernon
1731 * netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the
1732 common function to reduce a little bit the footprint (for all functions using
1733 only the "netif" parameter).
1734
1735 2007-10-03 Frédéric Bernon
1736 * netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down,
1737 netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce
1738 a little bit the footprint (for all functions using only the "netif" parameter).
1739
1740 2007-09-15 Frédéric Bernon
1741 * udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF
1742 option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for
1743 netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for
1744 IP_MULTICAST_TTL and IP_MULTICAST_IF.
1745
1746 2007-09-10 Frédéric Bernon
1747 * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles
1748 even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime()
1749 each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can
1750 decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but
1751 call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime()
1752 or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
1753 This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
1754 snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
1755 when it's queried (any direct call to "sysuptime" is changed by a call to
1756 snmp_get_sysuptime).
1757
1758 2007-09-09 Frédéric Bernon, Bill Florac
1759 * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP,
1760 and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags
1761 if you want IGMP on an interface. igmp_stop() is now called inside netif_remove().
1762 igmp_report_groups() is now called inside netif_set_link_up() (need to have
1763 LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait
1764 the next query message to receive the matching multicast streams).
1765
1766 2007-09-08 Frédéric Bernon
1767 * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains
1768 IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change).
1769 Use this new field to access to common pcb fields (ttl, tos, so_options, etc...).
1770 Enable to access to these fields with LWIP_TCP=0.
1771
1772 2007-09-05 Frédéric Bernon
1773 * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h,
1774 ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option
1775 LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default).
1776 Be careful, disabling ICMP make your product non-compliant to RFC1122, but
1777 help to reduce footprint, and to reduce "visibility" on the Internet.
1778
1779 2007-09-05 Frédéric Bernon, Bill Florac
1780 * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list
1781 for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new
1782 parameters have to be provided: a task name, and a task stack size. For this
1783 one, since it's platform dependant, you could define the best one for you in
1784 your lwipopts.h. For port maintainers, you can just add these new parameters
1785 in your sys_arch.c file, and but it's not mandatory, use them in your OS
1786 specific functions.
1787
1788 2007-09-05 Frédéric Bernon
1789 * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings
1790 inside init.c for task #7142 "Sanity check user-configurable values".
1791
1792 2007-09-04 Frédéric Bernon, Bill Florac
1793 * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by
1794 memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the
1795 value). It will avoid potential fragmentation problems, use a counter to know
1796 how many times a group is used on an netif, and free it when all applications
1797 leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity
1798 check if LWIP_IGMP!=0).
1799
1800 2007-09-03 Frédéric Bernon
1801 * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement".
1802 Initialize igmp_mac_filter to NULL in netif_add (this field should be set in
1803 the netif's "init" function). Use the "imr_interface" field (for socket layer)
1804 and/or the "interface" field (for netconn layer), for join/leave operations.
1805 The igmp_join/leavegroup first parameter change from a netif to an ipaddr.
1806 This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany).
1807
1808 2007-08-30 Frédéric Bernon
1809 * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions
1810 from api/api_lib". Now netbuf API is independant of netconn, and can be used
1811 with other API (application based on raw API, or future "socket2" API). Ports
1812 maintainers just have to add src/api/netbuf.c in their makefile/projects.
1813
1814 2007-08-30 Frédéric Bernon, Jonathan Larmour
1815 * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check
1816 user-configurable values".
1817
1818 2007-08-29 Frédéric Bernon
1819 * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start.
1820 igmp_start is call inside netif_add. Now, igmp initialization is in the same
1821 spirit than the others modules. Modify some IGMP debug traces.
1822
1823 2007-08-29 Frédéric Bernon
1824 * Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function"
1825 Add lwip_init function to regroup all modules initializations, and to provide
1826 a place to add code for task #7142 "Sanity check user-configurable values".
1827 Ports maintainers should remove direct initializations calls from their code,
1828 and add init.c in their makefiles. Note that lwip_init() function is called
1829 inside tcpip_init, but can also be used by raw api users since all calls are
1830 disabled when matching options are disabled. Also note that their is new options
1831 in opt.h, you should configure in your lwipopts.h (they are enabled per default).
1832
1833 2007-08-26 Marc Boucher
1834 * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL
1835 since they can under certain circumstances be called with an invalid conn
1836 pointer after the connection has been closed (and conn has been freed).
1837
1838 2007-08-25 Frédéric Bernon (Artem Migaev's Patch)
1839 * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up".
1840 Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set.
1841
1842 2007-08-22 Frédéric Bernon
1843 * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK
1844 to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release.
1845
1846 2007-08-22 Frédéric Bernon
1847 * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT &
1848 ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the
1849 name is tcpip_input (we keep the name of 1.2.0 function).
1850
1851 2007-08-17 Jared Grubb
1852 * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool
1853 settings into new memp_std.h and optional user file lwippools.h. This adds
1854 more dynamic mempools, and allows the user to create an arbitrary number of
1855 mempools for mem_malloc.
1856
1857 2007-08-16 Marc Boucher
1858 * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function;
1859 otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely
1860 close the connection.
1861
1862 2007-08-16 Marc Boucher
1863 * sockets.c: lwip_accept(): check netconn_peer() error return.
1864
1865 2007-08-16 Marc Boucher
1866 * mem.c, mem.h: Added mem_calloc().
1867
1868 2007-08-16 Marc Boucher
1869 * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT)
1870 for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG
1871 and starving other message types.
1872 Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API
1873
1874 2007-08-16 Marc Boucher
1875 * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf
1876 type and flgs (later renamed to flags).
1877 Use enum pbuf_flag as pbuf_type. Renumber PBUF_FLAG_*.
1878 Improved lwip_recvfrom(). TCP push now propagated.
1879
1880 2007-08-16 Marc Boucher
1881 * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global
1882 provided by etharp.
1883
1884 2007-08-16 Marc Boucher
1885 * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h,
1886 etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c:
1887 Added PPPoE support and various PPP improvements.
1888
1889 2007-07-25 Simon Goldschmidt
1890 * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial,
1891 making netbuf_copy_partial use this function.
1892
1893 2007-07-25 Simon Goldschmidt
1894 * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with
1895 2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and
1896 other stacks.
1897
1898 2007-07-13 Jared Grubb (integrated by Frédéric Bernon)
1899 * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add
1900 a link callback in the netif struct, and functions to handle it. Be carefull
1901 for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c)
1902 if you want to be sure to be compatible with future changes...
1903
1904 2007-06-30 Frédéric Bernon
1905 * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.
1906
1907 2007-06-21 Simon Goldschmidt
1908 * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both
1909 LWIP_AUTOIP =0 and =1 to remove redundant code.
1910
1911 2007-06-21 Simon Goldschmidt
1912 * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option
1913 MEM_USE_POOLS to use 4 pools with different sized elements instead of a
1914 heap. This both prevents memory fragmentation and gives a higher speed
1915 at the cost of more memory consumption. Turned off by default.
1916
1917 2007-06-21 Simon Goldschmidt
1918 * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of
1919 netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into
1920 int to be able to send a bigger buffer than 64K with one time (mainly
1921 used from lwip_send).
1922
1923 2007-06-21 Simon Goldschmidt
1924 * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write
1925 into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too.
1926
1927 2007-06-21 Simon Goldschmidt
1928 * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in
1929 netconn_write from api_lib.c to api_msg.c to also prevent multiple context-
1930 changes on low memory or empty send-buffer.
1931
1932 2007-06-18 Simon Goldschmidt
1933 * etharp.c, etharp.h: Changed etharp to use a defined hardware address length
1934 of 6 to avoid loading netif->hwaddr_len every time (since this file is only
1935 used for ethernet and struct eth_addr already had a defined length of 6).
1936
1937 2007-06-17 Simon Goldschmidt
1938 * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets
1939 to disable UDP checksum generation on transmit.
1940
1941 2007-06-13 Frédéric Bernon, Simon Goldschmidt
1942 * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid
1943 pointers or parameters, and let the possibility to redefined it in cc.h. Use
1944 this macro to check "conn" parameter in api_msg.c functions.
1945
1946 2007-06-11 Simon Goldschmidt
1947 * sockets.c, sockets.h: Added UDP lite support for sockets
1948
1949 2007-06-10 Simon Goldschmidt
1950 * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled
1951 by default) to switch off UDP-Lite support if not needed (reduces udp.c code
1952 size)
1953
1954 2007-06-09 Dominik Spies (integrated by Frédéric Bernon)
1955 * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h:
1956 AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and
1957 LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt
1958 (see TODO mark in the source code).
1959
1960 2007-06-09 Simon Goldschmidt
1961 * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for
1962 etharp_output() to match netif->output so etharp_output() can be used
1963 directly as netif->output to save one function call.
1964
1965 2007-06-08 Simon Goldschmidt
1966 * netif.h, ethernetif.c, slipif.c, loopif.c: Added define
1967 NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables,
1968 added initialization of those to ethernetif, slipif and loopif.
1969
1970 2007-05-18 Simon Goldschmidt
1971 * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF
1972 (defaulting to off for now) that can be set to 0 to send fragmented
1973 packets by passing PBUF_REFs down the stack.
1974
1975 2007-05-23 Frédéric Bernon
1976 * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP
1977 connections, such present in patch #5959.
1978
1979 2007-05-23 Frédéric Bernon
1980 * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx
1981 code in only one part...
1982
1983 2007-05-18 Simon Goldschmidt
1984 * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp
1985 elements to overflow. This is achieved by adding some bytes before and after
1986 each pool element (increasing their size, of course), filling them with a
1987 prominent value and checking them on freeing the element.
1988 Set it to 2 to also check every element in every pool each time memp_malloc()
1989 or memp_free() is called (slower but more helpful).
1990
1991 2007-05-10 Simon Goldschmidt
1992 * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for
1993 PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce
1994 code size.
1995
1996 2007-05-11 Frédéric Bernon
1997 * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c:
1998 Include a function pointer instead of a table index in the message to reduce
1999 footprint. Disable some part of lwip_send and lwip_sendto if some options are
2000 not set (LWIP_TCP, LWIP_UDP, LWIP_RAW).
2001
2002 2007-05-10 Simon Goldschmidt
2003 * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus
2004 \ extern "C" {' in all header files. Now you can write your application using
2005 the lwIP stack in C++ and simply #include the core files. Note I have left
2006 out the netif/ppp/*h header files for now, since I don't know which files are
2007 included by applications and which are for internal use only.
2008
2009 2007-05-09 Simon Goldschmidt
2010 * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library
2011 memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for
2012 situations where some compilers might inline the copy and save a function
2013 call. Also replaced all calls to memcpy() with calls to (S)MEMCPY().
2014
2015 2007-05-08 Simon Goldschmidt
2016 * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc())
2017 to be overriden in case the C-library malloc implementation is not protected
2018 against concurrent access.
2019
2020 2007-05-04 Simon Goldschmidt (Atte Kojo)
2021 * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending
2022 multiple packets to the same host.
2023
2024 2007-05-04 Frédéric Bernon, Jonathan Larmour
2025 * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible
2026 to corrupt remote addr/port connection state". Reduce problems "not enought memory" with
2027 netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between
2028 sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function.
2029 Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct,
2030 these fields are now renamed "addr" & "port".
2031
2032 2007-04-11 Jonathan Larmour
2033 * sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new
2034 sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return
2035 with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro
2036 by the port in sys_arch.h if desired.
2037
2038 2007-04-06 Frédéric Bernon, Simon Goldschmidt
2039 * opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API
2040 allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp
2041 clients, using new functions from netifapi.h. Disable as default (no port change to do).
2042
2043 2007-04-05 Frédéric Bernon
2044 * sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant.
2045
2046 2007-04-04 Simon Goldschmidt
2047 * arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x)
2048 use this for and architecture-independent form to tell the compiler you intentionally
2049 are not using this variable. Can be overriden in cc.h.
2050
2051 2007-03-28 Frédéric Bernon
2052 * opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to
2053 define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded
2054 string, point on one of your's ethernetif field, or alloc a string you will free yourself).
2055 It will be used by DHCP to register a client hostname, but can also be use when you call
2056 snmp_set_sysname.
2057
2058 2007-03-28 Frédéric Bernon
2059 * netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to
2060 initialize a network interface's flag with. It tell this interface is an ethernet
2061 device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility
2062 Support for IPv4" section 4.6) when interface is "up" with netif_set_up().
2063
2064 2007-03-26 Frédéric Bernon, Jonathan Larmour
2065 * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build
2066 time if you only use PPP or SLIP. The default is enable. Note we don't have to call
2067 etharp_init in your port's initilization sequence if you use tcpip.c, because this call
2068 is done in tcpip_init function.
2069
2070 2007-03-22 Frédéric Bernon
2071 * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the
2072 new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in
2073 your lwipopts.h. More, unused counters are not defined in the stats structs, and not
2074 display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined
2075 but never used. Fix msg_in.c with the correct #if test for a stat display.
2076
2077 2007-03-21 Kieran Mansley
2078 * netif.c, netif.h: Apply patch#4197 with some changes (originator: rireland@hmgsl.com).
2079 Provides callback on netif up/down state change.
2080
2081 2007-03-11 Frédéric Bernon, Mace Gael, Steve Reynolds
2082 * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, igmp.h, igmp.c,
2083 ip.c, netif.h, tcpip.c, opt.h:
2084 New configuration option LWIP_IGMP to enable IGMP processing. Based on only one
2085 filter per all network interfaces. Declare a new function in netif to enable to
2086 control the MAC filter (to reduce lwIP traffic processing).
2087
2088 2007-03-11 Frédéric Bernon
2089 * tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can
2090 be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this
2091 unless you know what you're doing (default are RFC1122 compliant). Note
2092 that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds.
2093
2094 2007-03-08 Frédéric Bernon
2095 * tcp.h: Keepalive values can be configured at compile time, but don't change
2096 this unless you know what you're doing (default are RFC1122 compliant).
2097
2098 2007-03-08 Frédéric Bernon
2099 * sockets.c, api.h, api_lib.c, tcpip.c, sys.h, sys.c, err.c, opt.h:
2100 Implement LWIP_SO_RCVTIMEO configuration option to enable/disable SO_RCVTIMEO
2101 on UDP sockets/netconn.
2102
2103 2007-03-08 Simon Goldschmidt
2104 * snmp_msg.h, msg_in.c: SNMP UDP ports can be configured at compile time.
2105
2106 2007-03-06 Frédéric Bernon
2107 * api.h, api_lib.c, sockets.h, sockets.c, tcpip.c, sys.h, sys.c, err.h:
2108 Implement SO_RCVTIMEO on UDP sockets/netconn.
2109
2110 2007-02-28 Kieran Mansley (based on patch from Simon Goldschmidt)
2111 * api_lib.c, tcpip.c, memp.c, memp.h: make API msg structs allocated
2112 on the stack and remove the API msg type from memp
2113
2114 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
2115 * sockets.h, sockets.c: Move socket initialization to new
2116 lwip_socket_init() function.
2117 NOTE: this changes the API with ports. Ports will have to be
2118 updated to call lwip_socket_init() now.
2119
2120 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
2121 * api_lib.c: Use memcpy in netbuf_copy_partial.
2122
2123
2124 ++ Bug fixes:
2125
2126 2008-03-17 Frédéric Bernon, Ed Kerekes
2127 * igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have
2128 some problems to fill the IP header on some targets, use now the
2129 ip.h macros to do it).
2130
2131 2008-03-13 Frédéric Bernon
2132 * sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using
2133 (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a
2134 TCP connection caused a crash. Note that using (lwip_)recvfrom
2135 like this is a bit slow and that using (lwip)getpeername is the
2136 good lwip way to do it (so, using recv is faster on tcp sockets).
2137
2138 2008-03-12 Frédéric Bernon, Jonathan Larmour
2139 * api_msg.c, contrib/apps/ping.c: Fix bug #22530 "api_msg.c's
2140 recv_raw() does not consume data", and the ping sample (with
2141 LWIP_SOCKET=1, the code did the wrong supposition that lwip_recvfrom
2142 returned the IP payload, without the IP header).
2143
2144 2008-03-04 Jonathan Larmour
2145 * mem.c, stats.c, mem.h: apply patch #6414 to avoid compiler errors
2146 and/or warnings on some systems where mem_size_t and size_t differ.
2147 * pbuf.c, ppp.c: Fix warnings on some systems with mem_malloc.
2148
2149 2008-03-04 Kieran Mansley (contributions by others)
2150 * Numerous small compiler error/warning fixes from contributions to
2151 mailing list after 1.3.0 release candidate made.
2152
2153 2008-01-25 Cui hengbin (integrated by Frédéric Bernon)
2154 * dns.c: Fix bug #22108 "DNS problem" caused by unaligned structures.
2155
2156 2008-01-15 Kieran Mansley
2157 * tcp_out.c: BUG20511. Modify persist timer to start when we are
2158 prevented from sending by a small send window, not just a zero
2159 send window.
2160
2161 2008-01-09 Jonathan Larmour
2162 * opt.h, ip.c: Rename IP_OPTIONS define to IP_OPTIONS_ALLOWED to avoid
2163 conflict with Linux system headers.
2164
2165 2008-01-06 Jonathan Larmour
2166 * dhcp.c: fix bug #19927: "DHCP NACK problem" by clearing any existing set IP
2167 address entirely on receiving a DHCPNAK, and restarting discovery.
2168
2169 2007-12-21 Simon Goldschmidt
2170 * sys.h, api_lib.c, api_msg.c, sockets.c: fix bug #21698: "netconn->recv_avail
2171 is not protected" by using new macros for interlocked access to modify/test
2172 netconn->recv_avail.
2173
2174 2007-12-20 Kieran Mansley (based on patch from Oleg Tyshev)
2175 * tcp_in.c: fix bug# 21535 (nrtx not reset correctly in SYN_SENT state)
2176
2177 2007-12-20 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
2178 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: fix bug #20199 (better handling
2179 of silly window avoidance and prevent lwIP from shrinking the window)
2180
2181 2007-12-04 Simon Goldschmidt
2182 * tcp.c, tcp_in.c: fix bug #21699 (segment leak in ooseq processing when last
2183 data packet was lost): add assert that all segment lists are empty in
2184 tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED
2185 state from LAST_ACK in tcp_process
2186
2187 2007-12-02 Simon Goldschmidt
2188 * sockets.h: fix bug #21654: exclude definition of struct timeval from #ifndef FD_SET
2189 If including <sys/time.h> for system-struct timeval, LWIP_TIMEVAL_PRIVATE now
2190 has to be set to 0 in lwipopts.h
2191
2192 2007-12-02 Simon Goldschmidt
2193 * api_msg.c, api_lib.c: fix bug #21656 (recvmbox problem in netconn API): always
2194 allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen
2195 netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox.
2196 This is a fix for thread-safety and allocates all items needed for a netconn
2197 when the netconn is created.
2198
2199 2007-11-30 Simon Goldschmidt
2200 * udp.c: first attempt to fix bug #21655 (DHCP doesn't work reliably with multiple
2201 netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed
2202 to netif->dhcp->pcb only (if that exists) and not to any other pcb for the same
2203 port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address)
2204
2205 2007-11-27 Simon Goldschmidt
2206 * ip.c: fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by
2207 letting ip_route only use netifs that are up.
2208
2209 2007-11-27 Simon Goldschmidt
2210 * err.h, api_lib.c, api_msg.c, sockets.c: Changed error handling: ERR_MEM, ERR_BUF
2211 and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and
2212 sockets block most operations once they have seen a fatal error.
2213
2214 2007-11-27 Simon Goldschmidt
2215 * udp.h, udp.c, dhcp.c: Implemented new function udp_sendto_if which takes the
2216 netif to send as an argument (to be able to send on netifs that are down).
2217
2218 2007-11-26 Simon Goldschmidt
2219 * tcp_in.c: Fixed bug #21582: pcb->acked accounting can be wrong when ACKs
2220 arrive out-of-order
2221
2222 2007-11-21 Simon Goldschmidt
2223 * tcp.h, tcp_out.c, api_msg.c: Fixed bug #20287: tcp_output_nagle sends too early
2224 Fixed the nagle algorithm; nagle now also works for all raw API applications
2225 and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY'
2226
2227 2007-11-12 Frédéric Bernon
2228 * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most
2229 of the netconn_peer and netconn_addr processing is done inside tcpip_thread
2230 context in do_getaddr.
2231
2232 2007-11-10 Simon Goldschmidt
2233 * etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can
2234 happen any time). Now the packet simply isn't enqueued when out of memory.
2235
2236 2007-11-01 Simon Goldschmidt
2237 * tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or
2238 TCP_MSS if that is smaller) as long as no MSS option is received from the
2239 remote host.
2240
2241 2007-11-01 Simon Goldschmidt
2242 * tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN)
2243 is now based on TCP_MSS instead of pcb->mss (on passive open now effectively
2244 sending our configured TCP_MSS instead of the one received).
2245
2246 2007-11-01 Simon Goldschmidt
2247 * tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was
2248 calculated based on the configured TCP_MSS, not on the MSS option received
2249 with SYN+ACK.
2250
2251 2007-10-09 Simon Goldschmidt
2252 * udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too
2253 short and also was generated wrong if checksum coverage != tot_len;
2254 receive: checksum was calculated wrong if checksum coverage != tot_len
2255
2256 2007-10-08 Simon Goldschmidt
2257 * mem.c: lfree was not updated in mem_realloc!
2258
2259 2007-10-07 Frédéric Bernon
2260 * sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential
2261 crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT:
2262 this change cause an API breakage for netconn_addr, since a parameter
2263 type change. Any compiler should cause an error without any changes in
2264 yours netconn_peer calls (so, it can't be a "silent change"). It also
2265 reduce a little bit the footprint for socket layer (lwip_getpeername &
2266 lwip_getsockname use now a common lwip_getaddrname function since
2267 netconn_peer & netconn_addr have the same parameters).
2268
2269 2007-09-20 Simon Goldschmidt
2270 * tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state)
2271 by checking tcp_tw_pcbs also
2272
2273 2007-09-19 Simon Goldschmidt
2274 * icmp.c: Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies)
2275
2276 2007-09-15 Mike Kleshov
2277 * mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used)
2278
2279 2007-09-06 Frédéric Bernon
2280 * several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove
2281 it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which
2282 already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h"
2283 if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h.
2284
2285 2007-08-30 Frédéric Bernon
2286 * igmp.h, igmp.c: Some changes to remove some redundant code, add some traces,
2287 and fix some coding style.
2288
2289 2007-08-28 Frédéric Bernon
2290 * tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any
2291 kind of packets. These packets are considered like Ethernet packets (payload
2292 pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets
2293 are considered like IP packets (payload pointing to iphdr).
2294
2295 2007-08-27 Frédéric Bernon
2296 * api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error
2297 problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state
2298 and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT).
2299
2300 2007-08-24 Kieran Mansley
2301 * inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy
2302 compiler (Paradigm C++)
2303
2304 2007-08-09 Frédéric Bernon, Bill Florac
2305 * stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement.
2306 Introduce IGMP_STATS to centralize statistics management.
2307
2308 2007-08-09 Frédéric Bernon, Bill Florac
2309 * udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast
2310 packet on a udp pcb binded on an netif's IP address, and not on "any".
2311
2312 2007-08-09 Frédéric Bernon, Bill Florac
2313 * igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement.
2314 This is mainly on using lookup/lookfor, and some coding styles...
2315
2316 2007-07-26 Frédéric Bernon (and "thedoctor")
2317 * igmp.c: Fix bug #20595 to accept IGMPv3 "Query" messages.
2318
2319 2007-07-25 Simon Goldschmidt
2320 * api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if
2321 tcp_output fails in tcp_close, the code in do_close_internal gets simpler
2322 (tcp_output is called again later from tcp timers).
2323
2324 2007-07-25 Simon Goldschmidt
2325 * ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old
2326 copy_from_pbuf, which illegally modified the given pbuf.
2327
2328 2007-07-25 Simon Goldschmidt
2329 * tcp_out.c: tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs:
2330 changed snd_queuelen++ to snd_queuelen += pbuf_clen(p).
2331
2332 2007-07-24 Simon Goldschmidt
2333 * api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the
2334 correct state (must be CLOSED).
2335
2336 2007-07-13 Thomas Taranowski (commited by Jared Grubb)
2337 * memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed
2338 allocation. It now returns NULL.
2339
2340 2007-07-13 Frédéric Bernon
2341 * api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in
2342 all error cases.
2343
2344 2007-07-13 Frédéric Bernon
2345 * api_msg.c: Fix bug #20315: possible memory leak problem if tcp_listen failed,
2346 because current code doesn't follow rawapi.txt documentation.
2347
2348 2007-07-13 Kieran Mansley
2349 * src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in
2350 out of sequence processing of received packets
2351
2352 2007-07-03 Simon Goldschmidt
2353 * nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an
2354 assumption is made that this pbuf is in one piece (i.e. not chained). These
2355 assumptions clash with the possibility of converting to fully pool-based
2356 pbuf implementations, where PBUF_RAM pbufs might be chained.
2357
2358 2007-07-03 Simon Goldschmidt
2359 * api.h, api_lib.c, api_msg.c: Final fix for bug #20021 and some other problems
2360 when closing tcp netconns: removed conn->sem, less context switches when
2361 closing, both netconn_close and netconn_delete should safely close tcp
2362 connections.
2363
2364 2007-07-02 Simon Goldschmidt
2365 * ipv4/ip.h, ipv6/ip.h, opt.h, netif.h, etharp.h, ipv4/ip.c, netif.c, raw.c,
2366 tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off)
2367 to cache ARP table indices with each pcb instead of single-entry cache for
2368 the complete stack.
2369
2370 2007-07-02 Simon Goldschmidt
2371 * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent
2372 warnings when assigning to smaller types.
2373
2374 2007-06-28 Simon Goldschmidt
2375 * tcp_out.c: Added check to prevent tcp_pcb->snd_queuelen from overflowing.
2376
2377 2007-06-28 Simon Goldschmidt
2378 * tcp.h: Fixed bug #20287: Fixed nagle algorithm (sending was done too early if
2379 a segment contained chained pbufs)
2380
2381 2007-06-28 Frédéric Bernon
2382 * autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute
2383 a "pseudo-random" value based on netif's MAC and some autoip fields. It's always
2384 possible to define this macro in your own lwipopts.h to always use C library's
2385 rand(). Note that autoip_create_rand_addr doesn't use this macro.
2386
2387 2007-06-28 Frédéric Bernon
2388 * netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option
2389 LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications
2390 in api_lib/api_msg (use pointers and not type with table, etc...)
2391
2392 2007-06-26 Simon Goldschmidt
2393 * udp.h: Fixed bug #20259: struct udp_hdr was lacking the packin defines.
2394
2395 2007-06-25 Simon Goldschmidt
2396 * udp.c: Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload
2397 for udp packets with no matching pcb.
2398
2399 2007-06-25 Simon Goldschmidt
2400 * udp.c: Fixed bug #20220: UDP PCB search in udp_input(): a non-local match
2401 could get udp input packets if the remote side matched.
2402
2403 2007-06-13 Simon Goldschmidt
2404 * netif.c: Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get
2405 changed in netif_set_ipaddr if previous netif->ip_addr.addr was 0.
2406
2407 2007-06-13 Simon Goldschmidt
2408 * api_msg.c: pcb_new sets conn->err if protocol is not implemented
2409 -> netconn_new_..() does not allocate a new connection for unsupported
2410 protocols.
2411
2412 2007-06-13 Frédéric Bernon, Simon Goldschmidt
2413 * api_lib.c: change return expression in netconn_addr and netconn_peer, because
2414 conn->err was reset to ERR_OK without any reasons (and error was lost)...
2415
2416 2007-06-13 Frédéric Bernon, Matthias Weisser
2417 * opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename
2418 MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid
2419 some macro names collision with some OS macros.
2420
2421 2007-06-11 Simon Goldschmidt
2422 * udp.c: UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0,
2423 create checksum over the complete packet. On RX, if it's < 8 (and not 0),
2424 discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both
2425 UDP & UDP Lite.
2426
2427 2007-06-11 Srinivas Gollakota & Oleg Tyshev
2428 * tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP flags"
2429 where TCP flags wasn't initialized in tcp_keepalive.
2430
2431 2007-06-03 Simon Goldschmidt
2432 * udp.c: udp_input(): Input pbuf was not freed if pcb had no recv function
2433 registered, p->payload was modified without modifying p->len if sending
2434 icmp_dest_unreach() (had no negative effect but was definitively wrong).
2435
2436 2007-06-03 Simon Goldschmidt
2437 * icmp.c: Corrected bug #19937: For responding to an icmp echo request, icmp
2438 re-used the input pbuf even if that didn't have enough space to include the
2439 link headers. Now the space is tested and a new pbuf is allocated for the
2440 echo response packet if the echo request pbuf isn't big enough.
2441
2442 2007-06-01 Simon Goldschmidt
2443 * sockets.c: Checked in patch #5914: Moved sockopt processing into tcpip_thread.
2444
2445 2007-05-23 Frédéric Bernon
2446 * api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only
2447 allocated by do_listen if success) and netconn_accept errors handling. In
2448 most of api_lib functions, we replace some errors checkings like "if (conn==NULL)"
2449 by ASSERT, except for netconn_delete.
2450
2451 2007-05-23 Frédéric Bernon
2452 * api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return
2453 an error code if it's impossible to fetch a pbuf on a TCP connection (and not
2454 directly close the recvmbox).
2455
2456 2007-05-22 Simon Goldschmidt
2457 * tcp.c: Fixed bug #1895 (tcp_bind not correct) by introducing a list of
2458 bound but unconnected (and non-listening) tcp_pcbs.
2459
2460 2007-05-22 Frédéric Bernon
2461 * sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only
2462 used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of
2463 sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features
2464 like "sys_timeout" in their application threads.
2465
2466 2007-05-22 Frédéric Bernon
2467 * api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see
2468 which parameters are used by which do_xxx function, and to avoid "misusing"
2469 parameters (patch #5938).
2470
2471 2007-05-22 Simon Goldschmidt
2472 * api_lib.c, api_msg.c, raw.c, api.h, api_msg.h, raw.h: Included patch #5938:
2473 changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto
2474 is only 8 bits wide. This affects the api, as there, the protocol was
2475 u16_t, too.
2476
2477 2007-05-18 Simon Goldschmidt
2478 * memp.c: addition to patch #5913: smaller pointer was returned but
2479 memp_memory was the same size -> did not save memory.
2480
2481 2007-05-16 Simon Goldschmidt
2482 * loopif.c, slipif.c: Fix bug #19729: free pbuf if netif->input() returns
2483 != ERR_OK.
2484
2485 2007-05-16 Simon Goldschmidt
2486 * api_msg.c, udp.c: If a udp_pcb has a local_ip set, check if it is the same
2487 as the one of the netif used for sending to prevent sending from old
2488 addresses after a netif address gets changed (partly fixes bug #3168).
2489
2490 2007-05-16 Frédéric Bernon
2491 * tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work
2492 with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in
2493 tcpip_init) because we have to be sure that network interfaces are already
2494 added (mac filter is updated only in igmp_init for the moment).
2495
2496 2007-05-16 Simon Goldschmidt
2497 * mem.c, memp.c: Removed semaphores from memp, changed sys_sem_wait calls
2498 into sys_arch_sem_wait calls to prevent timers from running while waiting
2499 for the heap. This fixes bug #19167.
2500
2501 2007-05-13 Simon Goldschmidt
2502 * tcp.h, sockets.h, sockets.c: Fixed bug from patch #5865 by moving the defines
2503 for socket options (lwip_set/-getsockopt) used with level IPPROTO_TCP from
2504 tcp.h to sockets.h.
2505
2506 2007-05-07 Simon Goldschmidt
2507 * mem.c: Another attempt to fix bug #17922.
2508
2509 2007-05-04 Simon Goldschmidt
2510 * pbuf.c, pbuf.h, etharp.c: Further update to ARP queueing: Changed pbuf_copy()
2511 implementation so that it can be reused (don't allocate the target
2512 pbuf inside pbuf_copy()).
2513
2514 2007-05-04 Simon Goldschmidt
2515 * memp.c: checked in patch #5913: in memp_malloc() we can return memp as mem
2516 to save a little RAM (next pointer of memp is not used while not in pool).
2517
2518 2007-05-03 "maq"
2519 * sockets.c: Fix ioctl FIONREAD when some data remains from last recv.
2520 (patch #3574).
2521
2522 2007-04-23 Simon Goldschmidt
2523 * loopif.c, loopif.h, opt.h, src/netif/FILES: fix bug #2595: "loopif results
2524 in NULL reference for incoming TCP packets". Loopif has to be configured
2525 (using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input()
2526 (multithreading environments, e.g. netif->input() = tcpip_input()) or
2527 putting packets on a list that is fed to the stack by calling loopif_poll()
2528 (single-thread / NO_SYS / polling environment where e.g.
2529 netif->input() = ip_input).
2530
2531 2007-04-17 Jonathan Larmour
2532 * pbuf.c: Use s32_t in pbuf_realloc(), as an s16_t can't reliably hold
2533 the difference between two u16_t's.
2534 * sockets.h: FD_SETSIZE needs to match number of sockets, which is
2535 MEMP_NUM_NETCONN in sockets.c right now.
2536
2537 2007-04-12 Jonathan Larmour
2538 * icmp.c: Reset IP header TTL in ICMP ECHO responses (bug #19580).
2539
2540 2007-04-12 Kieran Mansley
2541 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Modify way the retransmission
2542 timer is reset to fix bug#19434, with help from Oleg Tyshev.
2543
2544 2007-04-11 Simon Goldschmidt
2545 * etharp.c, pbuf.c, pbuf.h: 3rd fix for bug #11400 (arp-queuing): More pbufs than
2546 previously thought need to be copied (everything but PBUF_ROM!). Cleaned up
2547 pbuf.c: removed functions no needed any more (by etharp).
2548
2549 2007-04-11 Kieran Mansley
2550 * inet.c, ip_addr.h, sockets.h, sys.h, tcp.h: Apply patch #5745: Fix
2551 "Constant is long" warnings with 16bit compilers. Contributed by
2552 avatar@mmlab.cse.yzu.edu.tw
2553
2554 2007-04-05 Frédéric Bernon, Jonathan Larmour
2555 * api_msg.c: Fix bug #16830: "err_tcp() posts to connection mailbox when no pend on
2556 the mailbox is active". Now, the post is only done during a connect, and do_send,
2557 do_write and do_join_leave_group don't do anything if a previous error was signaled.
2558
2559 2007-04-03 Frédéric Bernon
2560 * ip.c: Don't set the IP_DF ("Don't fragment") flag in the IP header in IP output
2561 packets. See patch #5834.
2562
2563 2007-03-30 Frédéric Bernon
2564 * api_msg.c: add a "pcb_new" helper function to avoid redundant code, and to add
2565 missing pcb allocations checking (in do_bind, and for each raw_new). Fix style.
2566
2567 2007-03-30 Frédéric Bernon
2568 * most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with
2569 others environment defines (these were too "generic").
2570
2571 2007-03-28 Frédéric Bernon
2572 * api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal pbuf_alloc call
2573 result and can cause a crash. lwip_send now check netbuf_ref result.
2574
2575 2007-03-28 Simon Goldschmidt
2576 * sockets.c Remove "#include <errno.h>" from sockets.c to avoid multiple
2577 definition of macros (in errno.h and lwip/arch.h) if LWIP_PROVIDE_ERRNO is
2578 defined. This is the way it should have been already (looking at
2579 doc/sys_arch.txt)
2580
2581 2007-03-28 Kieran Mansley
2582 * opt.h Change default PBUF_POOL_BUFSIZE (again) to accomodate default MSS +
2583 IP and TCP headers *and* physical link headers
2584
2585 2007-03-26 Frédéric Bernon (based on patch from Dmitry Potapov)
2586 * api_lib.c: patch for netconn_write(), fixes a possible race condition which cause
2587 to send some garbage. It is not a definitive solution, but the patch does solve
2588 the problem for most cases.
2589
2590 2007-03-22 Frédéric Bernon
2591 * api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used).
2592
2593 2007-03-22 Frédéric Bernon
2594 * api_lib.c: somes resources couldn't be freed if there was errors during
2595 netconn_new_with_proto_and_callback.
2596
2597 2007-03-22 Frédéric Bernon
2598 * ethernetif.c: update netif->input calls to check return value. In older ports,
2599 it's a good idea to upgrade them, even if before, there could be another problem
2600 (access to an uninitialized mailbox).
2601
2602 2007-03-21 Simon Goldschmidt
2603 * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed
2604 by casting to unsigned).
2605
2606 2007-03-21 Frédéric Bernon
2607 * api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from
2608 api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a
2609 dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call.
2610 Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a
2611 faster and more reliable communication between api_lib and tcpip.
2612
2613 2007-03-21 Frédéric Bernon
2614 * opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0.
2615
2616 2007-03-21 Frédéric Bernon
2617 * api_msg.c, igmp.c, igmp.h: Fix C++ style comments
2618
2619 2007-03-21 Kieran Mansley
2620 * opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS +
2621 IP and TCP headers
2622
2623 2007-03-21 Kieran Mansley
2624 * Fix all uses of pbuf_header to check the return value. In some
2625 cases just assert if it fails as I'm not sure how to fix them, but
2626 this is no worse than before when they would carry on regardless
2627 of the failure.
2628
2629 2007-03-21 Kieran Mansley
2630 * sockets.c, igmp.c, igmp.h, memp.h: Fix C++ style comments and
2631 comment out missing header include in icmp.c
2632
2633 2007-03-20 Frédéric Bernon
2634 * memp.h, stats.c: Fix stats_display function where memp_names table wasn't
2635 synchronized with memp.h.
2636
2637 2007-03-20 Frédéric Bernon
2638 * tcpip.c: Initialize tcpip's mbox, and verify if initialized in tcpip_input,
2639 tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init problem with
2640 network interfaces. Also fix a compiler warning.
2641
2642 2007-03-20 Kieran Mansley
2643 * udp.c: Only try and use pbuf_header() to make space for headers if
2644 not a ROM or REF pbuf.
2645
2646 2007-03-19 Frédéric Bernon
2647 * api_msg.h, api_msg.c, tcpip.h, tcpip.c: Add return types to tcpip_apimsg()
2648 and api_msg_post().
2649
2650 2007-03-19 Frédéric Bernon
2651 * Remove unimplemented "memp_realloc" function from memp.h.
2652
2653 2007-03-11 Simon Goldschmidt
2654 * pbuf.c: checked in patch #5796: pbuf_alloc: len field claculation caused
2655 memory corruption.
2656
2657 2007-03-11 Simon Goldschmidt (based on patch from Dmitry Potapov)
2658 * api_lib.c, sockets.c, api.h, api_msg.h, sockets.h: Fixed bug #19251
2659 (missing `const' qualifier in socket functions), to get more compatible to
2660 standard POSIX sockets.
2661
2662 2007-03-11 Frédéric Bernon (based on patch from Dmitry Potapov)
2663 * sockets.c: Add asserts inside bind, connect and sendto to check input
2664 parameters. Remove excessive set_errno() calls after get_socket(), because
2665 errno is set inside of get_socket(). Move last sock_set_errno() inside
2666 lwip_close.
2667
2668 2007-03-09 Simon Goldschmidt
2669 * memp.c: Fixed bug #11400: New etharp queueing introduced bug: memp_memory
2670 was allocated too small.
2671
2672 2007-03-06 Simon Goldschmidt
2673 * tcpip.c: Initialize dhcp timers in tcpip_thread (if LWIP_DHCP) to protect
2674 the stack from concurrent access.
2675
2676 2007-03-06 Frédéric Bernon, Dmitry Potapov
2677 * tcpip.c, ip_frag.c, ethernetif.c: Fix some build problems, and a redundancy
2678 call to "lwip_stats.link.recv++;" in low_level_input() & ethernetif_input().
2679
2680 2007-03-06 Simon Goldschmidt
2681 * ip_frag.c, ip_frag.h: Reduce code size: don't include code in those files
2682 if IP_FRAG == 0 and IP_REASSEMBLY == 0
2683
2684 2007-03-06 Frédéric Bernon, Simon Goldschmidt
2685 * opt.h, ip_frag.h, tcpip.h, tcpip.c, ethernetif.c: add new configuration
2686 option named ETHARP_TCPIP_ETHINPUT, which enable the new tcpip_ethinput.
2687 Allow to do ARP processing for incoming packets inside tcpip_thread
2688 (protecting ARP layer against concurrent access). You can also disable
2689 old code using tcp_input with new define ETHARP_TCPIP_INPUT set to 0.
2690 Older ports have to use tcpip_ethinput.
2691
2692 2007-03-06 Simon Goldschmidt (based on patch from Dmitry Potapov)
2693 * err.h, err.c: fixed compiler warning "initialization dircards qualifiers
2694 from pointer target type"
2695
2696 2007-03-05 Frédéric Bernon
2697 * opt.h, sockets.h: add new configuration options (LWIP_POSIX_SOCKETS_IO_NAMES,
2698 ETHARP_TRUST_IP_MAC, review SO_REUSE)
2699
2700 2007-03-04 Frédéric Bernon
2701 * api_msg.c: Remove some compiler warnings : parameter "pcb" was never
2702 referenced.
2703
2704 2007-03-04 Frédéric Bernon
2705 * api_lib.c: Fix "[patch #5764] api_lib.c cleanup: after patch #5687" (from
2706 Dmitry Potapov).
2707 The api_msg struct stay on the stack (not moved to netconn struct).
2708
2709 2007-03-04 Simon Goldschmidt (based on patch from Dmitry Potapov)
2710 * pbuf.c: Fix BUG#19168 - pbuf_free can cause deadlock (if
2711 SYS_LIGHTWEIGHT_PROT=1 & freeing PBUF_RAM when mem_sem is not available)
2712 Also fixed cast warning in pbuf_alloc()
2713
2714 2007-03-04 Simon Goldschmidt
2715 * etharp.c, etharp.h, memp.c, memp.h, opt.h: Fix BUG#11400 - don't corrupt
2716 existing pbuf chain when enqueuing multiple pbufs to a pending ARP request
2717
2718 2007-03-03 Frédéric Bernon
2719 * udp.c: remove obsolete line "static struct udp_pcb *pcb_cache = NULL;"
2720 It is static, and never used in udp.c except udp_init().
2721
2722 2007-03-02 Simon Goldschmidt
2723 * tcpip.c: Moved call to ip_init(), udp_init() and tcp_init() from
2724 tcpip_thread() to tcpip_init(). This way, raw API connections can be
2725 initialized before tcpip_thread is running (e.g. before OS is started)
2726
2727 2007-03-02 Frédéric Bernon
2728 * rawapi.txt: Fix documentation mismatch with etharp.h about etharp_tmr's call
2729 interval.
2730
2731 2007-02-28 Kieran Mansley
2732 * pbuf.c: Fix BUG#17645 - ensure pbuf payload pointer is not moved
2733 outside the region of the pbuf by pbuf_header()
2734
2735 2007-02-28 Kieran Mansley
2736 * sockets.c: Fix BUG#19161 - ensure milliseconds timeout is non-zero
2737 when supplied timeout is also non-zero
2738
2739 (STABLE-1.2.0)
2740
2741 2006-12-05 Leon Woestenberg
2742 * CHANGELOG: Mention STABLE-1.2.0 release.
2743
2744 ++ New features:
2745
2746 2006-12-01 Christiaan Simons
2747 * mem.h, opt.h: Added MEM_LIBC_MALLOC option.
2748 Note this is a workaround. Currently I have no other options left.
2749
2750 2006-10-26 Christiaan Simons (accepted patch by Jonathan Larmour)
2751 * ipv4/ip_frag.c: rename MAX_MTU to IP_FRAG_MAX_MTU and move define
2752 to include/lwip/opt.h.
2753 * ipv4/lwip/ip_frag.h: Remove unused IP_REASS_INTERVAL.
2754 Move IP_REASS_MAXAGE and IP_REASS_BUFSIZE to include/lwip/opt.h.
2755 * opt.h: Add above new options.
2756
2757 2006-08-18 Christiaan Simons
2758 * tcp_{in,out}.c: added SNMP counters.
2759 * ipv4/ip.c: added SNMP counters.
2760 * ipv4/ip_frag.c: added SNMP counters.
2761
2762 2006-08-08 Christiaan Simons
2763 * etharp.{c,h}: added etharp_find_addr() to read
2764 (stable) ethernet/IP address pair from ARP table
2765
2766 2006-07-14 Christiaan Simons
2767 * mib_structs.c: added
2768 * include/lwip/snmp_structs.h: added
2769 * netif.{c,h}, netif/ethernetif.c: added SNMP statistics to netif struct
2770
2771 2006-07-06 Christiaan Simons
2772 * snmp/asn1_{enc,dec}.c added
2773 * snmp/mib2.c added
2774 * snmp/msg_{in,out}.c added
2775 * include/lwip/snmp_asn1.h added
2776 * include/lwip/snmp_msg.h added
2777 * doc/snmp_agent.txt added
2778
2779 2006-03-29 Christiaan Simons
2780 * inet.c, inet.h: Added platform byteswap support.
2781 Added LWIP_PLATFORM_BYTESWAP define (defaults to 0) and
2782 optional LWIP_PLATFORM_HTONS(), LWIP_PLATFORM_HTONL() macros.
2783
2784 ++ Bug fixes:
2785
2786 2006-11-30 Christiaan Simons
2787 * dhcp.c: Fixed false triggers of request_timeout.
2788
2789 2006-11-28 Christiaan Simons
2790 * netif.c: In netif_add() fixed missing clear of ip_addr, netmask, gw and flags.

2794 Partially accepted patch #5449 for ANSI C compatibility / build fixes.
2795 * ipv4/lwip/ip.h ipv6/lwip/ip.h: Corrected UDP-Lite protocol
2796 identifier from 170 to 136 (bug #17574).
2797
2798 2006-10-10 Christiaan Simons
2799 * api_msg.c: Fixed Nagle algorithm as reported by Bob Grice.
2800
2801 2006-08-17 Christiaan Simons
2802 * udp.c: Fixed bug #17200, added check for broadcast
2803 destinations for PCBs bound to a unicast address.
2804
2805 2006-08-07 Christiaan Simons
2806 * api_msg.c: Flushing TCP output in do_close() (bug #15926).
2807
2808 2006-06-27 Christiaan Simons
2809 * api_msg.c: Applied patch for cold case (bug #11135).
2810 In accept_function() ensure newconn->callback is always initialized.
2811
2812 2006-06-15 Christiaan Simons
2813 * mem.h: added MEM_SIZE_F alias to fix an ancient cold case (bug #1748),
2814 facilitate printing of mem_size_t and u16_t statistics.
2815
2816 2006-06-14 Christiaan Simons
2817 * api_msg.c: Applied patch #5146 to handle allocation failures
2818 in accept() by Kevin Lawson.
2819
2820 2006-05-26 Christiaan Simons
2821 * api_lib.c: Removed conn->sem creation and destruction
2822 from netconn_write() and added sys_sem_new to netconn_new_*.
2823
2824 (STABLE-1_1_1)
2825
2826 2006-03-03 Christiaan Simons
2827 * ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap
2828 access and added pbuf_alloc() return value checks.
2829
2830 2006-01-01 Leon Woestenberg <leon.woestenberg@gmx.net>
2831 * tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is
2832 now handled by the checksum routine properly.
2833
2834 2006-02-27 Leon Woestenberg <leon.woestenberg@gmx.net>
2835 * pbuf.c: Fix alignment; pbuf_init() would not work unless
2836 pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.)
2837
2838 2005-12-20 Leon Woestenberg <leon.woestenberg@gmx.net>
2839 * tcp.c: Remove PCBs which stay in LAST_ACK state too long. Patch
2840 submitted by Mitrani Hiroshi.
2841
2842 2005-12-15 Christiaan Simons
2843 * inet.c: Disabled the added summing routine to preserve code space.
2844
2845 2005-12-14 Leon Woestenberg <leon.woestenberg@gmx.net>
2846 * tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
2847 Added Curt McDowell's optimized checksumming routine for future
2848 inclusion. Need to create test case for unaliged, aligned, odd,
2849 even length combination of cases on various endianess machines.
2850
2851 2005-12-09 Christiaan Simons
2852 * inet.c: Rewrote standard checksum routine in proper portable C.
2853
2854 2005-11-25 Christiaan Simons
2855 * udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
2856 * *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
2857 u32_t, s32_t typedefs. This solves most debug word-length assumes.
2858
2859 2005-07-17 Leon Woestenberg <leon.woestenberg@gmx.net>
2860 * inet.c: Fixed unaligned 16-bit access in the standard checksum
2861 routine by Peter Jolasson.
2862 * slipif.c: Fixed implementation assumption of single-pbuf datagrams.
2863
2864 2005-02-04 Leon Woestenberg <leon.woestenberg@gmx.net>
2865 * tcp_out.c: Fixed uninitialized 'queue' referenced in memerr branch.
2866 * tcp_{out|in}.c: Applied patch fixing unaligned access.
2867
2868 2005-01-04 Leon Woestenberg <leon.woestenberg@gmx.net>
2869 * pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement.
2870
2871 2005-01-03 Leon Woestenberg <leon.woestenberg@gmx.net>
2872 * udp.c: UDP pcb->recv() was called even when it was NULL.
2873
2874 (STABLE-1_1_0)
2875
2876 2004-12-28 Leon Woestenberg <leon.woestenberg@gmx.net>
2877 * etharp.*: Disabled multiple packets on the ARP queue.
2878 This clashes with TCP queueing.
2879
2880 2004-11-28 Leon Woestenberg <leon.woestenberg@gmx.net>
2881 * etharp.*: Fixed race condition from ARP request to ARP timeout.
2882 Halved the ARP period, doubled the period counts.
2883 ETHARP_MAX_PENDING now should be at least 2. This prevents
2884 the counter from reaching 0 right away (which would allow
2885 too little time for ARP responses to be received).
2886
2887 2004-11-25 Leon Woestenberg <leon.woestenberg@gmx.net>
2888 * dhcp.c: Decline messages were not multicast but unicast.
2889 * etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
2890 Do not try hard to insert arbitrary packet's source address,
2891 etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
2892 etharp_query() now always DOES call ETHARP_TRY_HARD so that users
2893 querying an address will see it appear in the cache (DHCP could
2894 suffer from this when a server invalidly gave an in-use address.)
2895 * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
2896 comparing network addresses (identifiers), not the network masks
2897 themselves.
2898 * ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
2899 IP address actually belongs to the network of the given interface.
2900
2901 2004-11-24 Kieran Mansley <kjm25@cam.ac.uk>
2902 * tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.
2903
2904 (STABLE-1_1_0-RC1)
2905
2906 2004-10-16 Kieran Mansley <kjm25@cam.ac.uk>
2907 * tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
2908 even if one is already pending, if the rcv_wnd is above a threshold
2909 (currently TCP_WND/2). This avoids waiting for a timer to expire to send a
2910 delayed ACK in order to open the window if the stack is only receiving data.
2911
2912 2004-09-12 Kieran Mansley <kjm25@cam.ac.uk>
2913 * tcp*.*: Retransmit time-out handling improvement by Sam Jansen.
2914
2915 2004-08-20 Tony Mountifield <tony@softins.co.uk>
2916 * etharp.c: Make sure the first pbuf queued on an ARP entry
2917 is properly ref counted.
2918
2919 2004-07-27 Tony Mountifield <tony@softins.co.uk>
2920 * debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
2921 warnings about comparison.
2922 * pbuf.c: Stopped compiler complaining of empty if statement
2923 when LWIP_DEBUGF() empty. Closed an unclosed comment.
2924 * tcp.c: Stopped compiler complaining of empty if statement
2925 when LWIP_DEBUGF() empty.
2926 * ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
2927 * inet.c: Added a couple of casts to quiet the compiler.
2928 No need to test isascii(c) before isdigit(c) or isxdigit(c).
2929
2930 2004-07-22 Tony Mountifield <tony@softins.co.uk>
2931 * inet.c: Made data types consistent in inet_ntoa().
2932 Added casts for return values of checksum routines, to pacify compiler.
2933 * ip_frag.c, tcp_out.c, sockets.c, pbuf.c
2934 Small corrections to some debugging statements, to pacify compiler.
2935
2936 2004-07-21 Tony Mountifield <tony@softins.co.uk>
2937 * etharp.c: Removed spurious semicolon and added missing end-of-comment.
2938 * ethernetif.c Updated low_level_output() to match prototype for
2939 netif->linkoutput and changed low_level_input() similarly for consistency.
2940 * api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
2941 of raw_recv() in raw.h and so avoid compiler error.
2942 * sockets.c: Added trivial (int) cast to keep compiler happier.
2943 * ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.
2944
2945 (STABLE-1_0_0)
2946
2947 ++ Changes:
2948
2949 2004-07-05 Leon Woestenberg <leon.woestenberg@gmx.net>
2950 * sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure
2951 your cc.h file defines this either 1 or 0. If non-defined,
2952 defaults to 1.
2953 * .c: Added <string.h> and <errno.h> includes where used.
2954 * etharp.c: Made some array indices unsigned.
2955
2956 2004-06-27 Leon Woestenberg <leon.woestenberg@gmx.net>
2957 * netif.*: Added netif_set_up()/down().
2958 * dhcp.c: Changes to restart program flow.
2959
2960 2004-05-07 Leon Woestenberg <leon.woestenberg@gmx.net>
2961 * etharp.c: In find_entry(), instead of a list traversal per candidate, do a
2962 single-pass lookup for different candidates. Should exploit locality.
2963
2964 2004-04-29 Leon Woestenberg <leon.woestenberg@gmx.net>
2965 * tcp*.c: Cleaned up source comment documentation for Doxygen processing.
2966 * opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC.
2967 * etharp.c: update_arp_entry() only adds new ARP entries when adviced to by
2968 the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option.
2969
2970 ++ Bug fixes:
2971
2972 2004-04-27 Leon Woestenberg <leon.woestenberg@gmx.net>
2973 * etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution
2974 suggested by Timmy Brolin. Fix for 32-bit processors that cannot access
2975 non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix
2976 is to prefix the 14-bit Ethernet headers with two padding bytes.
2977
2978 2004-04-23 Leon Woestenberg <leon.woestenberg@gmx.net>
2979 * ip_addr.c: Fix in the ip_addr_isbroadcast() check.
2980 * etharp.c: Fixed the case where the packet that initiates the ARP request
2981 is not queued, and gets lost. Fixed the case where the packets destination
2982 address is already known; we now always queue the packet and perform an ARP
2983 request.
2984
2985 (STABLE-0_7_0)
2986
2987 ++ Bug fixes:
2988
2989 * Fixed TCP bug for SYN_SENT to ESTABLISHED state transition.
2990 * Fixed TCP bug in dequeueing of FIN from out of order segment queue.
2991 * Fixed two possible NULL references in rare cases.
2992
2993 (STABLE-0_6_6)
2994
2995 ++ Bug fixes:
2996
2997 * Fixed DHCP which did not include the IP address in DECLINE messages.
2998
2999 ++ Changes:
3000
3001 * etharp.c has been hauled over a bit.
3002
3003 (STABLE-0_6_5)
3004
3005 ++ Bug fixes:
3006
3007 * Fixed TCP bug induced by bad window resizing with unidirectional TCP traffic.
3008 * Packets sent from ARP queue had invalid source hardware address.
3009
3010 ++ Changes:
3011
3012 * Pass-by ARP requests do now update the cache.
3013
3014 ++ New features:
3015
3016 * No longer dependent on ctype.h.
3017 * New socket options.
3018 * Raw IP pcb support.
3019
3020 (STABLE-0_6_4)
3021
3022 ++ Bug fixes:
3023
3024 * Some debug formatters and casts fixed.
3025 * Numereous fixes in PPP.
3026
3027 ++ Changes:
3028
3029 * DEBUGF now is LWIP_DEBUGF
3030 * pbuf_dechain() has been re-enabled.
3031 * Mentioned the changed use of CVS branches in README.
3032
3033 (STABLE-0_6_3)
3034
3035 ++ Bug fixes:
3036
3037 * Fixed pool pbuf memory leak in pbuf_alloc().
3038 Occured if not enough PBUF_POOL pbufs for a packet pbuf chain.
3039 Reported by Savin Zlobec.
3040
3041 * PBUF_POOL chains had their tot_len field not set for non-first
3042 pbufs. Fixed in pbuf_alloc().
3043
3044 ++ New features:
3045
3046 * Added PPP stack contributed by Marc Boucher
3047
3048 ++ Changes:
3049
3050 * Now drops short packets for ICMP/UDP/TCP protocols. More robust.
3051
3052 * ARP queueuing now queues the latest packet instead of the first.
3053 This is the RFC recommended behaviour, but can be overridden in
3054 lwipopts.h.
3055
3056 (0.6.2)
3057
3058 ++ Bugfixes:
3059
3060 * TCP has been fixed to deal with the new use of the pbuf->ref
3061 counter.
3062
3063 * DHCP dhcp_inform() crash bug fixed.
3064
3065 ++ Changes:
3066
3067 * Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
3068 pbuf_refresh(). This has sped up pbuf pool operations considerably.
3069 Implemented by David Haas.
3070
3071 (0.6.1)
3072
3073 ++ New features:
3074
3075 * The packet buffer implementation has been enhanced to support
3076 zero-copy and copy-on-demand for packet buffers which have their
3077 payloads in application-managed memory.
3078 Implemented by David Haas.
3079
3080 Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
3081 if an outgoing packet can be directly sent on the link, or perform
3082 a copy-on-demand when necessary.
3083
3084 The application can safely assume the packet is sent, and the RAM
3085 is available to the application directly after calling udp_send()
3086 or similar function.
3087
3088 ++ Bugfixes:
3089
3090 * ARP_QUEUEING should now correctly work for all cases, including
3091 PBUF_REF.
3092 Implemented by Leon Woestenberg.
3093
3094 ++ Changes:
3095
3096 * IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
3097 to a '0.0.0.0' IP address.
3098
3099 * The packet buffer implementation is changed. The pbuf->ref counter
3100 meaning has changed, and several pbuf functions have been
3101 adapted accordingly.
3102
3103 * netif drivers have to be changed to set the hardware address length field
3104 that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).
3105 See the contrib/ports/c16x cs8900 driver as a driver example.
3106
3107 * netif's have a dhcp field that must be initialized to NULL by the driver.
3108 See the contrib/ports/c16x cs8900 driver as a driver example.
3109
3110 (0.5.x) This file has been unmaintained up to 0.6.1. All changes are
3111 logged in CVS but have not been explained here.
3112
3113 (0.5.3) Changes since version 0.5.2
3114
3115 ++ Bugfixes:
3116
3117 * memp_malloc(MEMP_API_MSG) could fail with multiple application
3118 threads because it wasn't protected by semaphores.
3119
3120 ++ Other changes:
3121
3122 * struct ip_addr now packed.
3123
3124 * The name of the time variable in arp.c has been changed to ctime
3125 to avoid conflicts with the time() function.
3126
3127 (0.5.2) Changes since version 0.5.1
3128
3129 ++ New features:
3130
3131 * A new TCP function, tcp_tmr(), now handles both TCP timers.
3132
3133 ++ Bugfixes:
3134
3135 * A bug in tcp_parseopt() could cause the stack to hang because of a
3136 malformed TCP option.
3137
3138 * The address of new connections in the accept() function in the BSD
3139 socket library was not handled correctly.
3140
3141 * pbuf_dechain() did not update the ->tot_len field of the tail.
3142
3143 * Aborted TCP connections were not handled correctly in all
3144 situations.
3145
3146 ++ Other changes:
3147
3148 * All protocol header structs are now packed.
3149
3150 * The ->len field in the tcp_seg structure now counts the actual
3151 amount of data, and does not add one for SYN and FIN segments.
3152
3153 (0.5.1) Changes since version 0.5.0
3154
3155 ++ New features:
3156
3157 * Possible to run as a user process under Linux.
3158
3159 * Preliminary support for cross platform packed structs.
3160
3161 * ARP timer now implemented.
3162
3163 ++ Bugfixes:
3164
3165 * TCP output queue length was badly initialized when opening
3166 connections.
3167
3168 * TCP delayed ACKs were not sent correctly.
3169
3170 * Explicit initialization of BSS segment variables.
3171
3172 * read() in BSD socket library could drop data.
3173
3174 * Problems with memory alignment.
3175
3176 * Situations when all TCP buffers were used could lead to
3177 starvation.
3178
3179 * TCP MSS option wasn't parsed correctly.
3180
3181 * Problems with UDP checksum calculation.
3182
3183 * IP multicast address tests had endianess problems.
3184
3185 * ARP requests had wrong destination hardware address.
3186
3187 ++ Other changes:
3188
3189 * struct eth_addr changed from u16_t[3] array to u8_t[6].
3190
3191 * A ->linkoutput() member was added to struct netif.
3192
3193 * TCP and UDP ->dest_* struct members where changed to ->remote_*.
3194
3195 * ntoh* macros are now null definitions for big endian CPUs.
3196
3197 (0.5.0) Changes since version 0.4.2
3198
3199 ++ New features:
3200
3201 * Redesigned operating system emulation layer to make porting easier.
3202
3203 * Better control over TCP output buffers.
3204
3205 * Documenation added.
3206
3207 ++ Bugfixes:
3208
3209 * Locking issues in buffer management.
3210
3211 * Bugfixes in the sequential API.
3212
3213 * IP forwarding could cause memory leakage. This has been fixed.
3214
3215 ++ Other changes:
3216
3217 * Directory structure somewhat changed; the core/ tree has been
3218 collapsed.
3219
3220 (0.4.2) Changes since version 0.4.1
3221
3222 ++ New features:
3223
3224 * Experimental ARP implementation added.
3225
3226 * Skeleton Ethernet driver added.
3227
3228 * Experimental BSD socket API library added.
3229
3230 ++ Bugfixes:
3231
3232 * In very intense situations, memory leakage could occur. This has
3233 been fixed.
3234
3235 ++ Other changes:
3236
3237 * Variables named "data" and "code" have been renamed in order to
3238 avoid name conflicts in certain compilers.
3239
3240 * Variable++ have in appliciable cases been translated to ++variable
3241 since some compilers generate better code in the latter case.
3242
3243 (0.4.1) Changes since version 0.4
3244
3245 ++ New features:
3246
3247 * TCP: Connection attempts time out earlier than data
3248 transmissions. Nagle algorithm implemented. Push flag set on the
3249 last segment in a burst.
3250
3251 * UDP: experimental support for UDP-Lite extensions.
3252
3253 ++ Bugfixes:
3254
3255 * TCP: out of order segments were in some cases handled incorrectly,
3256 and this has now been fixed. Delayed acknowledgements was broken
3257 in 0.4, has now been fixed. Binding to an address that is in use
3258 now results in an error. Reset connections sometimes hung an
3259 application; this has been fixed.
3260
3261 * Checksum calculation sometimes failed for chained pbufs with odd
3262 lengths. This has been fixed.
3263
3264 * API: a lot of bug fixes in the API. The UDP API has been improved
3265 and tested. Error reporting and handling has been
3266 improved. Logical flaws and race conditions for incoming TCP
3267 connections has been found and removed.
3268
3269 * Memory manager: alignment issues. Reallocating memory sometimes
3270 failed, this has been fixed.
3271
3272 * Generic library: bcopy was flawed and has been fixed.
3273
3274 ++ Other changes:
3275
3276 * API: all datatypes has been changed from generic ones such as
3277 ints, to specified ones such as u16_t. Functions that return
3278 errors now have the correct type (err_t).
3279
3280 * General: A lot of code cleaned up and debugging code removed. Many
3281 portability issues have been fixed.
3282
3283 * The license was changed; the advertising clause was removed.
3284
3285 * C64 port added.
3286
3287 * Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri
3288 Kosunen, Mikael Caleres, and Frits Wilmink for reporting and
3289 fixing bugs!
3290
3291 (0.4) Changes since version 0.3.1
3292
3293 * Memory management has been radically changed; instead of
3294 allocating memory from a shared heap, memory for objects that are
3295 rapidly allocated and deallocated is now kept in pools. Allocation
3296 and deallocation from those memory pools is very fast. The shared
3297 heap is still present but is used less frequently.
3298
3299 * The memory, memory pool, and packet buffer subsystems now support
3300 4-, 2-, or 1-byte alignment.
3301
3302 * "Out of memory" situations are handled in a more robust way.
3303
3304 * Stack usage has been reduced.
3305
3306 * Easier configuration of lwIP parameters such as memory usage,
3307 TTLs, statistics gathering, etc. All configuration parameters are
3308 now kept in a single header file "lwipopts.h".
3309
3310 * The directory structure has been changed slightly so that all
3311 architecture specific files are kept under the src/arch
3312 hierarchy.
3313
3314 * Error propagation has been improved, both in the protocol modules
3315 and in the API.
3316
3317 * The code for the RTXC architecture has been implemented, tested
3318 and put to use.
3319
3320 * Bugs have been found and corrected in the TCP, UDP, IP, API, and
3321 the Internet checksum modules.
3322
3323 * Bugs related to porting between a 32-bit and a 16-bit architecture
3324 have been found and corrected.
3325
3326 * The license has been changed slightly to conform more with the
3327 original BSD license, including the advertisement clause.
3328
3329 (0.3.1) Changes since version 0.3
3330
3331 * Fix of a fatal bug in the buffer management. Pbufs with allocated
3332 RAM never returned the RAM when the pbuf was deallocated.
3333
3334 * TCP congestion control, window updates and retransmissions did not
3335 work correctly. This has now been fixed.
3336
3337 * Bugfixes in the API.
3338
3339 (0.3) Changes since version 0.2
3340
3341 * New and improved directory structure. All include files are now
3342 kept in a dedicated include/ directory.
3343
3344 * The API now has proper error handling. A new function,
3345 netconn_err(), now returns an error code for the connection in
3346 case of errors.
3347
3348 * Improvements in the memory management subsystem. The system now
3349 keeps a pointer to the lowest free memory block. A new function,
3350 mem_malloc2() tries to allocate memory once, and if it fails tries
3351 to free some memory and retry the allocation.
3352
3353 * Much testing has been done with limited memory
3354 configurations. lwIP now does a better job when overloaded.
3355
3356 * Some bugfixes and improvements to the buffer (pbuf) subsystem.
3357
3358 * Many bugfixes in the TCP code:
3359
3360 - Fixed a bug in tcp_close().
3361
3362 - The TCP receive window was incorrectly closed when out of
3363 sequence segments was received. This has been fixed.
3364
3365 - Connections are now timed-out of the FIN-WAIT-2 state.
3366
3367 - The initial congestion window could in some cases be too
3368 large. This has been fixed.
3369
3370 - The retransmission queue could in some cases be screwed up. This
3371 has been fixed.
3372
3373 - TCP RST flag now handled correctly.
3374
3375 - Out of sequence data was in some cases never delivered to the
3376 application. This has been fixed.
3377
3378 - Retransmitted segments now contain the correct acknowledgment
3379 number and advertised window.
3380
3381 - TCP retransmission timeout backoffs are not correctly computed
3382 (ala BSD). After a number of retransmissions, TCP now gives up
3383 the connection.
3384
3385 * TCP connections now are kept on three lists, one for active
3386 connections, one for listening connections, and one for
3387 connections that are in TIME-WAIT. This greatly speeds up the fast
3388 timeout processing for sending delayed ACKs.
3389
3390 * TCP now provides proper feedback to the application when a
3391 connection has been successfully set up.
3392
3393 * More comments have been added to the code. The code has also been
3394 somewhat cleaned up.
3395
3396 (0.2) Initial public release.
