7 ++ New features:
8
9 2014-01-17: Jiri Engelthaler
10 * icmp, icmp6, opt.h: patch #8027: Completed HW checksuming for IPv4 and
11 IPv6 ICMP's
12
13 2012-03-25: Simon Goldschmidt (idea by Mason)
14 * posix/*: added posix-compatibility include files posix/netdb.h and posix/sys/socket.h
15 which are a simple wrapper to the correct lwIP include files.
16
17 2012-01-16: Simon Goldschmidt
18 * opt.h, icmp.c: Added option CHECKSUM_GEN_ICMP
19
20 2011-12-17: Simon Goldschmidt
21 * ip.h: implemented API functions to access so_options of IP pcbs (UDP, TCP, RAW)
22 (fixes bug #35061)
23
24 2011-09-27: Simon Goldschmidt
25 * opt.h, tcp.c, tcp_in.c: Implemented limiting data on ooseq queue (task #9989)
26 (define TCP_OOSEQ_MAX_BYTES / TCP_OOSEQ_MAX_PBUFS in lwipopts.h)
27
28 2011-09-21: Simon Goldschmidt
29 * opt.h, api.h, api_lib.c, api_msg.h/.c, sockets.c: Implemented timeout on
30 send (TCP only, bug #33820)
31
32 2011-09-21: Simon Goldschmidt
33 * init.c: Converted runtime-sanity-checks into compile-time checks that can
34 be disabled (since runtime checks can often not be seen on embedded targets)
35
36 2011-09-11: Simon Goldschmidt
37 * ppp.h, ppp_impl.h: splitted ppp.h to an internal and external header file
38 to get a clear separation of which functions an application or port may use
39 (task #11281)
40
41 2011-09-11: Simon Goldschmidt
42 * opt.h, tcp_impl.h, tcp.c, udp.h/.c: Added a config option to randomize
43 initial local TCP/UDP ports (so that different port ranges are used after
44 a reboot; bug #33818; this one added tcp_init/udp_init functions again)
45
46 2011-09-03: Simon Goldschmidt
47 * dhcp.c: DHCP uses LWIP_RAND() for xid's (bug #30302)
48
49 2011-08-24: Simon Goldschmidt
50 * opt.h, netif.h/.c: added netif remove callback (bug #32397)
51
52 2011-07-26: Simon Goldschmidt
53 * etharp.c: ETHARP_SUPPORT_VLAN: add support for an external VLAN filter
54 function instead of only checking for one VLAN (define ETHARP_VLAN_CHECK_FN)
55
56 2011-07-21: Simon Goldschmidt (patch by hanhui)
57 * ip4.c, etharp.c, pbuf.h: bug #33634 ip_forward() have a faulty behaviour:
58 Added pbuf flags to mark incoming packets as link-layer broadcast/multicast.
59 Also added code to allow ip_forward() to forward non-broadcast packets to
60 the input netif (set IP_FORWARD_ALLOW_TX_ON_RX_NETIF==1).
61
62 2011-07-21: Simon Goldschmidt
63 * sockets.c, opt.h: (bug #30185): added LWIP_FIONREAD_LINUXMODE that makes
64 ioctl/FIONREAD return the size of the next pending datagram.
65
66 2011-06-26: Simon Goldschmidt (patch by Cameron Gutman)
67 * tcp.c, tcp_out.c: bug #33604: added some more asserts to check that
68 pcb->state != LISTEN
69
70 2011-05-25: Simon Goldschmidt
71 * again nearly the whole stack, renamed ip.c to ip4.c, ip_addr.c to ip4_addr.c,
72 combined ipv4/ipv6 inet_chksum.c, added ip.h, ip_addr.h: Combined IPv4
73 and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP
74 code so that the code is more readable.
75
76 2011-05-17: Patch by Ivan Delamer (only checked in by Simon Goldschmidt)
77 * nearly the whole stack: Finally, we got decent IPv6 support, big thanks to
78 Ivan! (this is work in progress: we're just post release anyway :-)
79
80 2011-05-14: Simon Goldschmidt (patch by Stéphane Lesage)

424 IP_MULTICAST_LOOP at socket- and raw-API level.
425
426 2010-06-16: Simon Goldschmidt
427 * ip.c: Added an optional define (LWIP_IP_ACCEPT_UDP_PORT) that can allow
428 link-layer-addressed UDP traffic to be received while a netif is down (just
429 like DHCP during configuration)
430
431 2010-05-22: Simon Goldschmidt
432 * many many files: bug #27352: removed packing from ip_addr_t, the packed
433 version is now only used in protocol headers. Added global storage for
434 current src/dest IP address while in input functions.
435
436 2010-05-16: Simon Goldschmidt
437 * def.h: task #10391: Add preprocessor-macros for compile-time htonl
438 calculation (and use them throughout the stack where applicable)
439
440 2010-05-16: Simon Goldschmidt
441 * opt.h, memp_std.h, memp.c, ppp_oe.h/.c: PPPoE now uses its own MEMP pool
442 instead of the heap (moved struct pppoe_softc from ppp_oe.c to ppp_oe.h)
443
444 2010-05-16: Simon Goldschmidt
445 * opt.h, memp_std.h, dns.h/.c: DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses its own
446 MEMP pool instead of the heap
447
448 2010-05-13: Simon Goldschmidt
449 * tcp.c, udp.c: task #6995: Implement SO_REUSEADDR (correctly), added
450 new option SO_REUSE_RXTOALL to pass received UDP broadcast/multicast
451 packets to more than one pcb.
452
453 2010-05-02: Simon Goldschmidt
454 * netbuf.h/.c, sockets.c, api_msg.c: use checksum-on-copy for sending
455 UDP data for LWIP_NETIF_TX_SINGLE_PBUF==1
456
457 2010-04-30: Simon Goldschmidt
458 * udp.h/.c, pbuf.h/.c: task #6849: added udp_send(_to/_if) functions that
459 take a precalculated checksum, added pbuf_fill_chksum() to copy data
460 into a pbuf and at the same time calculating the checksum for that data
461
462 2010-04-29: Simon Goldschmidt
463 * ip_addr.h, etharp.h/.c, autoip.c: Create overridable macros for copying
464 2-byte-aligned IP addresses and MAC addresses
465
466 2010-04-28: Patch by Bill Auerbach
467 * ip.c: Inline generating IP checksum to save a function call
468
469 2010-04-14: Simon Goldschmidt
470 * tcpip.h/.c, timers.c: Added an overridable define to get informed when the
471 tcpip_thread processes messages or timeouts to implement a watchdog.
472
473 2010-03-28: Simon Goldschmidt
474 * ip_frag.c: create a new (contiguous) PBUF_RAM for every outgoing
475 fragment if LWIP_NETIF_TX_SINGLE_PBUF==1
476
477 2010-03-27: Simon Goldschmidt
478 * etharp.c: Speedup TX by moving code from find_entry to etharp_output/
479 etharp_query to prevent unnecessary function calls (inspired by
480 patch #7135).
481
482 2010-03-20: Simon Goldschmidt
483 * opt.h, tcpip.c/.h: Added an option to disable tcpip_(un)timeout code
484 since the linker cannot do this automatically to save space.
485
486 2010-03-20: Simon Goldschmidt
487 * opt.h, etharp.c/.h: Added support for static ARP table entries
488
489 2010-03-14: Simon Goldschmidt
490 * tcp_impl.h, tcp_out.c, inet_chksum.h/.c: task #6849: Calculate checksum
491 when creating TCP segments, not when (re-)transmitting them.
492
493 2010-03-07: Simon Goldschmidt
494 * sockets.c: bug #28775 (select/event_callback: only check select_cb_list
495 on change) plus use SYS_LIGHTWEIGHT_PROT to protect the select code.
496 This should speed up receiving data on sockets as the select code in
497 event_callback is only executed when select is waiting.
498
499 2010-03-06: Simon Goldschmidt
500 * tcp_out.c: task #7013 (Create option to have all packets delivered to
501 netif->output in one piece): Always copy to try to create single pbufs
502 in tcp_write.
503
504 2010-03-06: Simon Goldschmidt
505 * api.h, api_lib.c, sockets.c: task #10167 (sockets: speed up TCP recv
506 by not allocating a netbuf): added function netconn_recv_tcp_pbuf()
507 for tcp netconns to receive pbufs, not netbufs; use that function
508 for tcp sockets.
509
510 2010-03-05: Jakob Ole Stoklundsen / Simon Goldschmidt
511 * opt.h, tcp.h, tcp_impl.h, tcp.c, tcp_in.c, tcp_out.c: task #7040:
512 Work on tcp_enqueue: Don't waste memory when chaining segments,
513 added option TCP_OVERSIZE to prevent creating many small pbufs when
514 calling tcp_write with many small blocks of data. Instead, pbufs are
515 allocated larger than needed and the space is used for later calls to
516 tcp_write.
517
518 2010-02-21: Simon Goldschmidt
519 * stats.c/.h: Added const char* name to mem- and memp-stats for easier
520 debugging.
521
522 2010-02-21: Simon Goldschmidt
523 * tcp.h (and usages), added tcp_impl.h: Splitted API and internal
524 implementation of tcp to make API usage cleare to application programmers
525
526 2010-02-14: Simon Goldschmidt/Stephane Lesage
527 * ip_addr.h: Improved some defines working on ip addresses, added faster
528 macro to copy addresses that cannot be NULL
529
530 2010-02-13: Simon Goldschmidt
531 * api.h, api_lib.c, api_msg.c, sockets.c: task #7865 (implement non-
532 blocking send operation)
533
534 2010-02-12: Simon Goldschmidt
535 * sockets.c/.h: Added a minimal version of posix fctl() to have a
536 standardised way to set O_NONBLOCK for nonblocking sockets.
537
538 2010-02-12: Simon Goldschmidt
539 * dhcp.c/.h, autoip.c/.h: task #10139 (Prefer statically allocated
540 memory): added autoip_set_struct() and dhcp_set_struct() to let autoip
541 and dhcp work with user-allocated structs instead of callin mem_malloc
542
543 2010-02-12: Simon Goldschmidt/Jeff Barber
544 * tcp.c/h: patch #6865 (SO_REUSEADDR for TCP): if pcb.so_options has
545 SOF_REUSEADDR set, allow binding to endpoint in TIME_WAIT
546
547 2010-02-12: Simon Goldschmidt
548 * sys layer: task #10139 (Prefer statically allocated memory): converted
549 mbox and semaphore functions to take pointers to sys_mbox_t/sys_sem_t;
550 converted sys_mbox_new/sys_sem_new to take pointers and return err_t;
551 task #7212: Add Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX
552 to let sys.h use binary semaphores instead of mutexes - as before)
553
554 2010-02-09: Simon Goldschmidt (Simon Kallweit)
555 * timers.c/.h: Added function sys_restart_timeouts() from patch #7085
556 (Restart system timeout handling)
557
558 2010-02-09: Simon Goldschmidt
559 * netif.c/.h, removed loopif.c/.h: task #10153 (Integrate loopif into
560 netif.c) - loopif does not have to be created by the port any more,
561 just define LWIP_HAVE_LOOPIF to 1.
562
563 2010-02-08: Simon Goldschmidt
564 * inet.h, ip_addr.c/.h: Added reentrant versions of inet_ntoa/ipaddr_ntoa
565 inet_ntoa_r/ipaddr_ntoa_r
566
567 2010-02-08: Simon Goldschmidt
568 * netif.h: Added netif_s/get_igmp_mac_filter() macros
569
570 2010-02-05: Simon Goldschmidt
571 * netif.h: Added function-like macros to get/set the hostname on a netif
572
573 2010-02-04: Simon Goldschmidt
574 * nearly every file: Replaced struct ip_addr by typedef ip_addr_t to
575 make changing the actual implementation behind the typedef easier.
576
577 2010-02-01: Simon Goldschmidt
578 * opt.h, memp_std.h, dns.h, netdb.c, memp.c: Let netdb use a memp pool
579 for allocating memory when getaddrinfo() is called.
580
581 2010-01-31: Simon Goldschmidt
582 * dhcp.h, dhcp.c: Reworked the code that parses DHCP options: parse
583 them once instead of parsing for every option. This also removes
584 the need for mem_malloc from dhcp_recv and makes it possible to
585 correctly retrieve the BOOTP file.
586
587 2010-01-30: simon Goldschmidt
588 * sockets.c: Use SYS_LIGHTWEIGHT_PROT instead of a semaphore to protect
589 the sockets array.

598 plus many cleanups in socket & netconn API.
599
600 2010-01-27: Simon Goldschmidt
601 * opt.h, tcp.h, init.c, api_msg.c: Added TCP_SNDQUEUELOWAT corresponding

603
604 2010-01-26: Simon Goldschmidt
605 * snmp: Use memp pools for snmp instead of the heap; added 4 new pools.
606
607 2010-01-14: Simon Goldschmidt
608 * ppp.c/.h: Fixed bug #27856: PPP: Set netif link- and status-callback
609 by adding ppp_set_netif_statuscallback()/ppp_set_netif_linkcallback()
610
611 2010-01-13: Simon Goldschmidt
612 * mem.c: The heap now may be moved to user-defined memory by defining
613 LWIP_RAM_HEAP_POINTER as a void pointer to that memory's address
614 (patch #6966 and bug #26133)
615
616 2010-01-10: Simon Goldschmidt (Bill Auerbach)
617 * opt.h, memp.c: patch #6822 (Add option to place memory pools in
618 separate arrays)
619
620 2010-01-10: Simon Goldschmidt
621 * init.c, igmp.c: patch #6463 (IGMP - Adding Random Delay): added define
622 LWIP_RAND() for lwip-wide randomization (to be defined in cc.h)
623
624 2009-12-31: Simon Goldschmidt
625 * tcpip.c, init.c, memp.c, sys.c, memp_std.h, sys.h, tcpip.h
626 added timers.c/.h: Separated timer implementation from semaphore/mbox
627 implementation, moved timer implementation to timers.c/.h, timers are
628 now only called from tcpip_thread or by explicitly checking them.
629 (TASK#7235)
630
631 2009-12-27: Simon Goldschmidt
632 * opt.h, etharp.h/.c, init.c, tcpip.c: Added an additional option
633 LWIP_ETHERNET to support ethernet without ARP (necessary for pure PPPoE)
634
635
636 ++ Bugfixes:
637
638 2011-04-20: Simon Goldschmidt

642 * tcp.c, udp.c: Fixed bug #33048 (Bad range for IP source port numbers) by
643 using ports in the IANA private/dynamic range (49152 through 65535).

645 2011-03-29: Simon Goldschmidt, patch by Emil Lhungdahl:
646 * etharp.h/.c: Fixed broken VLAN support.
647
648 2011-03-27: Simon Goldschmidt
649 * tcp.c: Fixed bug #32926 (TCP_RMV(&tcp_bound_pcbs) is called on unbound tcp
650 pcbs) by checking if the pcb was bound (local_port != 0).
651
652 2011-03-27: Simon Goldschmidt

662 route.
663
664 2011-03-22: Simon Goldschmidt

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

672
673 2011-03-13: Simon Goldschmidt
674 * sockets.c: fixed bug #32769 (ESHUTDOWN is linux-specific) by fixing
675 err_to_errno_table (ERR_CLSD: ENOTCONN instead of ESHUTDOWN), ERR_ISCONN:
676 use EALRADY instead of -1
677
678 2011-03-13: Simon Goldschmidt
679 * api_lib.c: netconn_accept: return ERR_ABRT instead of ERR_CLSD if the

681 procedure).
682
683 2011-03-13: Simon Goldschmidt
684 * tcp.c: tcp_bind: return ERR_VAL instead of ERR_ISCONN when trying to bind

733 no-copy TCP writes will never succeed.
734
735 2010-11-20: Simon Goldschmidt
736 * dns.c: Fixed bug #31701: Error return value from dns_gethostbyname() does
737 not match documentation: return ERR_ARG instead of ERR_VAL if not

739
740 2010-10-20: Simon Goldschmidt
741 * sockets.h: Fixed bug #31385: sizeof(struct sockaddr) is 30 but should be 16
742
743 2010-10-05: Simon Goldschmidt
744 * dhcp.c: Once again fixed #30038: DHCP/AutoIP cooperation failed when

829
830 2010-03-26: Simon Goldschmidt
831 * various files: Fixed compiling with different options disabled (TCP/UDP),

848 * opt.h, etharp.h: Fixed bug #29148 (Incorrect PBUF_POOL_BUFSIZE for ports
849 where ETH_PAD_SIZE > 0) by moving definition of ETH_PAD_SIZE to opt.h
850 and basing PBUF_LINK_HLEN on it.
851
852 2010-03-08: Simon Goldschmidt
853 * netif.c, ipv4/ip.c: task #10241 (AutoIP: don't break existing connections
854 when assiging routable address): when checking incoming packets and
855 aborting existing connection on address change, filter out link-local
856 addresses.
857
858 2010-03-06: Simon Goldschmidt
859 * sockets.c: Fixed LWIP_NETIF_TX_SINGLE_PBUF for LWIP_TCPIP_CORE_LOCKING
860
861 2010-03-06: Simon Goldschmidt
862 * ipv4/ip.c: Don't try to forward link-local addresses
863
864 2010-03-06: Simon Goldschmidt
865 * etharp.c: Fixed bug #29087: etharp: don't send packets for LinkLocal-
866 addresses to gw
867
868 2010-03-05: Simon Goldschmidt
869 * dhcp.c: Fixed bug #29072: Correctly set ciaddr based on message-type
870 and state.
871
872 2010-03-05: Simon Goldschmidt
873 * api_msg.c: Correctly set TCP_WRITE_FLAG_MORE when netconn_write is split
874 into multiple calls to tcp_write.
875
876 2010-02-21: Simon Goldschmidt
877 * opt.h, mem.h, dns.c: task #10140: Remove DNS_USES_STATIC_BUF (keep
878 the implementation of DNS_USES_STATIC_BUF==1)
879
880 2010-02-20: Simon Goldschmidt
881 * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Task #10088: Correctly implement
882 close() vs. shutdown(). Now the application does not get any more
883 recv callbacks after calling tcp_close(). Added tcp_shutdown().
884
885 2010-02-19: Simon Goldschmidt
886 * mem.c/.h, pbuf.c: Renamed mem_realloc() to mem_trim() to prevent
887 confusion with realloc()
888
889 2010-02-15: Simon Goldschmidt/Stephane Lesage
890 * netif.c/.h: Link status does not depend on LWIP_NETIF_LINK_CALLBACK
891 (fixes bug #28899)
892
893 2010-02-14: Simon Goldschmidt
894 * netif.c: Fixed bug #28877 (Duplicate ARP gratuitous packet with
895 LWIP_NETIF_LINK_CALLBACK set on) by only sending if both link- and
896 admin-status of a netif are up
897
898 2010-02-14: Simon Goldschmidt
899 * opt.h: Disable ETHARP_TRUST_IP_MAC by default since it slows down packet
900 reception and is not really necessary
901
902 2010-02-14: Simon Goldschmidt
903 * etharp.c/.h: Fixed ARP input processing: only add a new entry if a
904 request was directed as us (RFC 826, Packet Reception), otherwise
905 only update existing entries; internalized some functions
906
907 2010-02-14: Simon Goldschmidt
908 * netif.h, etharp.c, tcpip.c: Fixed bug #28183 (ARP and TCP/IP cannot be
909 disabled on netif used for PPPoE) by adding a new netif flag
910 (NETIF_FLAG_ETHERNET) that tells the stack the device is an ethernet
911 device but prevents usage of ARP (so that ethernet_input can be used
912 for PPPoE).
913
914 2010-02-12: Simon Goldschmidt
915 * netif.c: netif_set_link_up/down: only do something if the link state
916 actually changes
917
918 2010-02-12: Simon Goldschmidt/Stephane Lesage
919 * api_msg.c: Fixed bug #28865 (Cannot close socket/netconn in non-blocking
920 connect)
921
922 2010-02-12: Simon Goldschmidt
923 * mem.h: Fixed bug #28866 (mem_realloc function defined in mem.h)
924
925 2010-02-09: Simon Goldschmidt
926 * api_lib.c, api_msg.c, sockets.c, api.h, api_msg.h: Fixed bug #22110
927 (recv() makes receive window update for data that wasn't received by
928 application)
929
930 2010-02-09: Simon Goldschmidt/Stephane Lesage
931 * sockets.c: Fixed bug #28853 (lwip_recvfrom() returns 0 on receive time-out
932 or any netconn_recv() error)
933
934 2010-02-09: Simon Goldschmidt
935 * ppp.c: task #10154 (PPP: Update snmp in/out counters for tx/rx packets)
936
937 2010-02-09: Simon Goldschmidt
938 * netif.c: For loopback packets, adjust the stats- and snmp-counters
939 for the loopback netif.
940
941 2010-02-08: Simon Goldschmidt
942 * igmp.c/.h, ip.h: Moved most defines from igmp.h to igmp.c for clarity
943 since they are not used anywhere else.
944
945 2010-02-08: Simon Goldschmidt (Stéphane Lesage)
946 * igmp.c, igmp.h, stats.c, stats.h: Improved IGMP stats
947 (patch from bug #28798)
948
949 2010-02-08: Simon Goldschmidt (Stéphane Lesage)
950 * igmp.c: Fixed bug #28798 (Error in "Max Response Time" processing) and
951 another bug when LWIP_RAND() returns zero.
952
953 2010-02-04: Simon Goldschmidt
954 * nearly every file: Use macros defined in ip_addr.h (some of them new)
955 to work with IP addresses (preparation for bug #27352 - Change ip_addr
956 from struct to typedef (u32_t) - and better code).
957
958 2010-01-31: Simon Goldschmidt
959 * netif.c: Don't call the link-callback from netif_set_up/down() since
960 this invalidly retriggers DHCP.
961
962 2010-01-29: Simon Goldschmidt
963 * ip_addr.h, inet.h, def.h, inet.c, def.c, more: Cleanly separate the
964 portability file inet.h and its contents from the stack: moved htonX-
965 functions to def.h (and the new def.c - they are not ipv4 dependent),
966 let inet.h depend on ip_addr.h and not the other way round.
967 This fixes bug #28732.
968
969 2010-01-28: Kieran Mansley
970 * tcp.c: Ensure ssthresh >= 2*MSS
971
972 2010-01-27: Simon Goldschmidt
973 * tcp.h, tcp.c, tcp_in.c: Fixed bug #27871: Calling tcp_abort() in recv
974 callback can lead to accessing unallocated memory. As a consequence,
975 ERR_ABRT means the application has called tcp_abort()!
976
977 2010-01-25: Simon Goldschmidt
978 * snmp_structs.h, msg_in.c: Partly fixed bug #22070 (MIB_OBJECT_WRITE_ONLY
979 not implemented in SNMP): write-only or not-accessible are still
980 returned by getnext (though not by get)
981
982 2010-01-24: Simon Goldschmidt
983 * snmp: Renamed the private mib node from 'private' to 'mib_private' to
984 not use reserved C/C++ keywords
985
986 2010-01-23: Simon Goldschmidt
987 * sockets.c: Fixed bug #28716: select() returns 0 after waiting for less
988 than 1 ms
989
990 2010-01-21: Simon Goldschmidt
991 * tcp.c, api_msg.c: Fixed bug #28651 (tcp_connect: no callbacks called
992 if tcp_enqueue fails) both in raw- and netconn-API
993
994 2010-01-19: Simon Goldschmidt
995 * api_msg.c: Fixed bug #27316: netconn: Possible deadlock in err_tcp
996
997 2010-01-18: Iordan Neshev/Simon Goldschmidt
998 * src/netif/ppp: reorganised PPP sourcecode to 2.3.11 including some
999 bugfix backports from 2.4.x.
1000
1001 2010-01-18: Simon Goldschmidt
1002 * mem.c: Fixed bug #28679: mem_realloc calculates mem_stats wrong
1003
1004 2010-01-17: Simon Goldschmidt
1005 * api_lib.c, api_msg.c, (api_msg.h, api.h, sockets.c, tcpip.c):
1006 task #10102: "netconn: clean up conn->err threading issues" by adding
1007 error return value to struct api_msg_msg
1008
1009 2010-01-17: Simon Goldschmidt
1010 * api.h, api_lib.c, sockets.c: Changed netconn_recv() and netconn_accept()
1011 to return err_t (bugs #27709 and #28087)
1012
1013 2010-01-14: Simon Goldschmidt
1014 * ...: Use typedef for function prototypes throughout the stack.
1015
1016 2010-01-13: Simon Goldschmidt
1017 * api_msg.h/.c, api_lib.c: Fixed bug #26672 (close connection when receive
1018 window = 0) by correctly draining recvmbox/acceptmbox
1019
1020 2010-01-11: Simon Goldschmidt
1021 * pap.c: Fixed bug #13315 (PPP PAP authentication can result in
1022 erroneous callbacks) by copying the code from recent pppd
1023
1024 2010-01-10: Simon Goldschmidt
1025 * raw.c: Fixed bug #28506 (raw_bind should filter received packets)
1026
1027 2010-01-10: Simon Goldschmidt
1028 * tcp.h/.c: bug #28127 (remove call to tcp_output() from tcp_ack(_now)())
1029
1030 2010-01-08: Simon Goldschmidt
1031 * sockets.c: Fixed bug #28519 (lwip_recvfrom bug with len > 65535)
1032
1033 2010-01-08: Simon Goldschmidt
1034 * dns.c: Copy hostname for DNS_LOCAL_HOSTLIST_IS_DYNAMIC==1 since string
1035 passed to dns_local_addhost() might be volatile
1036
1037 2010-01-07: Simon Goldschmidt
1038 * timers.c, tcp.h: Call tcp_timer_needed() with NO_SYS==1, too
1039
1040 2010-01-06: Simon Goldschmidt
1041 * netdb.h: Fixed bug #28496: missing include guards in netdb.h
1042
1043 2009-12-31: Simon Goldschmidt
1044 * many ppp files: Reorganised PPP source code from ucip structure to pppd
1045 structure to easily compare our code against the pppd code (around v2.3.1)
1046
1047 2009-12-27: Simon Goldschmidt
1048 * tcp_in.c: Another fix for bug #28241 (ooseq processing) and adapted
1049 unit test
1050

1101
1102 2009-11-29: Simon Goldschmidt
1103 * tcp_in.c: Fixed bug #28054: Two segments with FIN flag on the out-of-

1105
1106 2009-11-29: Simon Goldschmidt
1107 * pbuf.c: Fixed bug #28064: pbuf_alloc(PBUF_POOL) is not thread-safe by
1108 queueing a call into tcpip_thread to free ooseq-bufs if the pool is empty
1109
1110 2009-11-26: Simon Goldschmidt
1111 * tcp.h: Fixed bug #28098: Nagle can prevent fast retransmit from sending
1112 segment
1113

1163 testing for valid reply
1164
1165 2009-10-19: Simon Goldschmidt
1166 * dhcp.c: Removed most calls to udp_connect since they aren't necessary

1268 * init.h: Added LWIP_VERSION to get the current version of the stack
1269
1270 2009-02-11 Simon Goldschmidt (suggested by Gottfried Spitaler)
1271 * opt.h, memp.h/.c: added MEMP_MEM_MALLOC to use mem_malloc/mem_free instead
1272 of the pool allocator (can save code size with MEM_LIBC_MALLOC if libc-malloc
1273 is otherwise used)
1274
1275 2009-01-28 Jonathan Larmour (suggested by Bill Bauerbach)
1276 * ipv4/inet_chksum.c, ipv4/lwip/inet_chksum.h: inet_chksum_pseudo_partial()
1277 is only used by UDPLITE at present, so conditionalise it.
1278
1279 2008-12-03 Simon Goldschmidt (base on patch from Luca Ceresoli)
1280 * autoip.c: checked in (slightly modified) patch #6683: Customizable AUTOIP
1281 "seed" address. This should reduce AUTOIP conflicts if
1282 LWIP_AUTOIP_CREATE_SEED_ADDR is overridden.
1283
1284 2008-10-02 Jonathan Larmour and Rishi Khan
1285 * sockets.c (lwip_accept): Return EWOULDBLOCK if would block on non-blocking
1286 socket.
1287
1288 2008-06-30 Simon Goldschmidt
1289 * mem.c, opt.h, stats.h: fixed bug #21433: Calling mem_free/pbuf_free from
1290 interrupt context isn't safe: LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT allows
1291 mem_free to run between mem_malloc iterations. Added illegal counter for
1292 mem stats.
1293
1294 2008-06-27 Simon Goldschmidt
1295 * stats.h/.c, some other files: patch #6483: stats module improvement:
1296 Added defines to display each module's statistic individually, added stats
1297 defines for MEM, MEMP and SYS modules, removed (unused) rexmit counter.
1298
1299 2008-06-17 Simon Goldschmidt
1300 * err.h: patch #6459: Made err_t overridable to use a more efficient type
1301 (define LWIP_ERR_T in cc.h)
1302
1303 2008-06-17 Simon Goldschmidt
1304 * slipif.c: patch #6480: Added a configuration option for slipif for symmetry
1305 to loopif
1306
1307 2008-06-17 Simon Goldschmidt (patch by Luca Ceresoli)
1308 * netif.c, loopif.c, ip.c, netif.h, loopif.h, opt.h: Checked in slightly
1309 modified version of patch # 6370: Moved loopif code to netif.c so that
1310 loopback traffic is supported on all netifs (all local IPs).
1311 Added option to limit loopback packets for each netifs.
1312

1352
1353 2009-05-06 Simon Goldschmidt
1354 * inet_chksum.c: On little endian architectures, use LWIP_PLATFORM_HTONS (if

1383
1384 2009-04-29 Frédéric Bernon
1385 * raw.c, udp.c, init.c, opt.h, ip.h, sockets.h: bug #26309: Implement the
1386 SO(F)_BROADCAST filter for all API layers. Avoid the unindented reception
1387 of broadcast packets even when this option wasn't set. Port maintainers
1388 which want to enable this filter have to set IP_SOF_BROADCAST=1 in opt.h.
1389 If you want this option also filter broadcast on recv operations, you also
1390 have to set IP_SOF_BROADCAST_RECV=1 in opt.h.
1391

1400
1401 2009-04-25 Simon Goldschmidt
1402 * memp.c, mem.c, memp.h, mem_std.h: bug #26213 "Problem with memory allocation
1403 when debugging": memp_sizes contained the wrong sizes (including sanity
1404 regions); memp pools for MEM_USE_POOLS were too small
1405
1406 2009-04-24 Simon Goldschmidt, Frédéric Bernon
1407 * inet.c: patch #6765: Fix a small problem with the last changes (incorrect

1409 end of line)
1410
1411 2009-04-19 Simon Goldschmidt

1484
1485 2009-02-16 Simon Goldschmidt
1486 * sockets.h/.c, api_*.h/.c: fixed arguments of socket functions to match the standard;

1507 in state SYN_RCVD is close.
1508
1509 2009-01-28 Jonathan Larmour
1510 * pbuf.c: reclaim pbufs from TCP out-of-sequence segments if we run
1511 out of pool pbufs.
1512
1513 2008-12-19 Simon Goldschmidt
1514 * many files: patch #6699: fixed some warnings on platform where sizeof(int) == 2
1515
1516 2008-12-10 Tamas Somogyi, Frédéric Bernon

1533 padding is included.
1534
1535 2008-09-30 Jonathan Larmour
1536 * sockets.c (lwip_accept): check addr isn't NULL. If it's valid, do an
1537 assertion check that addrlen isn't NULL.
1538
1539 2008-09-30 Jonathan Larmour
1540 * tcp.c: Fix bug #24227, wrong error message in tcp_bind.

1545
1546 2008-08-14 Simon Goldschmidt
1547 * api_msg.c: fixed bug #23847: do_close_internal references freed memory (when

1549
1550 2008-07-08 Frédéric Bernon
1551 * stats.h: Fix some build bugs introduced with patch #6483 (missing some parameters

1553
1554 2008-06-24 Jonathan Larmour
1555 * tcp_in.c: Fix for bug #23693 as suggested by Art R. Ensure cseg is unused
1556 if tcp_seg_copy fails.
1557
1558 2008-06-17 Simon Goldschmidt

1561
1562 2008-05-30 Kieran Mansley
1563 * tcp_in.c Remove redundant "if" statement, and use real rcv_wnd
1564 rather than rcv_ann_wnd when deciding if packets are in-window.
1565 Contributed by <[email protected]>
1566
1567 2008-05-30 Kieran Mansley

1577 (flag now cleared)
1578
1579 2008-03-27 Simon Goldschmidt
1580 * mem.c, tcpip.c, tcpip.h, opt.h: fixed bug #21433 (Calling mem_free/pbuf_free
1581 from interrupt context isn't safe): set LWIP_USE_HEAP_FROM_INTERRUPT to 1
1582 in lwipopts.h or use pbuf_free_callback(p)/mem_free_callback(m) to free pbufs
1583 or heap memory from interrupt context
1584
1585 2008-03-26 Simon Goldschmidt

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

2782 outside the region of the pbuf by pbuf_header()
2783
2784 2007-02-28 Kieran Mansley
2785 * sockets.c: Fix BUG#19161 - ensure milliseconds timeout is non-zero
2786 when supplied timeout is also non-zero

2789
2790 2006-12-05 Leon Woestenberg
2791 * CHANGELOG: Mention STABLE-1.2.0 release.
2792
2793 ++ New features:
2794
2795 2006-12-01 Christiaan Simons
2796 * mem.h, opt.h: Added MEM_LIBC_MALLOC option.

2828 2006-03-29 Christiaan Simons
2829 * inet.c, inet.h: Added platform byteswap support.
2830 Added LWIP_PLATFORM_BYTESWAP define (defaults to 0) and
2831 optional LWIP_PLATFORM_HTONS(), LWIP_PLATFORM_HTONL() macros.
2832
2833 ++ Bug fixes:
2834
2835 2006-11-30 Christiaan Simons
2836 * dhcp.c: Fixed false triggers of request_timeout.
2837
2838 2006-11-28 Christiaan Simons

2840
2841 2006-10-11 Christiaan Simons
2842 * api_lib.c etharp.c, ip.c, memp.c, stats.c, sys.{c,h} tcp.h:
2843 Partially accepted patch #5449 for ANSI C compatibility / build fixes.
2844 * ipv4/lwip/ip.h ipv6/lwip/ip.h: Corrected UDP-Lite protocol

2846
2847 2006-10-10 Christiaan Simons
2848 * api_msg.c: Fixed Nagle algorithm as reported by Bob Grice.
2849
2850 2006-08-17 Christiaan Simons

2852 destinations for PCBs bound to a unicast address.
2853
2854 2006-08-07 Christiaan Simons
2855 * api_msg.c: Flushing TCP output in do_close() (bug #15926).
2856
2857 2006-06-27 Christiaan Simons
2858 * api_msg.c: Applied patch for cold case (bug #11135).
2859 In accept_function() ensure newconn->callback is always initialized.
2860
2861 2006-06-15 Christiaan Simons
2862 * mem.h: added MEM_SIZE_F alias to fix an ancient cold case (bug #1748),
2863 facilitate printing of mem_size_t and u16_t statistics.
2864
2865 2006-06-14 Christiaan Simons
2866 * api_msg.c: Applied patch #5146 to handle allocation failures
2867 in accept() by Kevin Lawson.
2868
2869 2006-05-26 Christiaan Simons
2870 * api_lib.c: Removed conn->sem creation and destruction
2871 from netconn_write() and added sys_sem_new to netconn_new_*.
2872
2873(STABLE-1_1_1)
2874
2875 2006-03-03 Christiaan Simons
2876 * ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap
2877 access and added pbuf_alloc() return value checks.
2878
2879 2006-01-01 Leon Woestenberg <[email protected]>
2880 * tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is
2881 now handled by the checksum routine properly.
2882
2883 2006-02-27 Leon Woestenberg <[email protected]>
2884 * pbuf.c: Fix alignment; pbuf_init() would not work unless
2885 pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.)
2886
2887 2005-12-20 Leon Woestenberg <[email protected]>
2888 * tcp.c: Remove PCBs which stay in LAST_ACK state too long. Patch
2889 submitted by Mitrani Hiroshi.
2890
2891 2005-12-15 Christiaan Simons
2892 * inet.c: Disabled the added summing routine to preserve code space.
2893
2894 2005-12-14 Leon Woestenberg <[email protected]>
2895 * tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
2896 Added Curt McDowell's optimized checksumming routine for future
2897 inclusion. Need to create test case for unaliged, aligned, odd,
2898 even length combination of cases on various endianess machines.
2899
2900 2005-12-09 Christiaan Simons
2901 * inet.c: Rewrote standard checksum routine in proper portable C.
2902
2903 2005-11-25 Christiaan Simons
2904 * udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
2905 * *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
2906 u32_t, s32_t typedefs. This solves most debug word-length assumes.
2907
2908 2005-07-17 Leon Woestenberg <[email protected]>
2909 * inet.c: Fixed unaligned 16-bit access in the standard checksum
2910 routine by Peter Jolasson.
2911 * slipif.c: Fixed implementation assumption of single-pbuf datagrams.
2912
2913 2005-02-04 Leon Woestenberg <[email protected]>
2914 * tcp_out.c: Fixed uninitialized 'queue' referenced in memerr branch.
2915 * tcp_{out|in}.c: Applied patch fixing unaligned access.
2916
2917 2005-01-04 Leon Woestenberg <[email protected]>
2918 * pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement.
2919
2920 2005-01-03 Leon Woestenberg <[email protected]>
2921 * udp.c: UDP pcb->recv() was called even when it was NULL.
2922
2923(STABLE-1_1_0)
2924
2925 2004-12-28 Leon Woestenberg <[email protected]>
2926 * etharp.*: Disabled multiple packets on the ARP queue.
2927 This clashes with TCP queueing.
2928
2929 2004-11-28 Leon Woestenberg <[email protected]>
2930 * etharp.*: Fixed race condition from ARP request to ARP timeout.
2931 Halved the ARP period, doubled the period counts.
2932 ETHARP_MAX_PENDING now should be at least 2. This prevents
2933 the counter from reaching 0 right away (which would allow
2934 too little time for ARP responses to be received).
2935
2936 2004-11-25 Leon Woestenberg <[email protected]>
2937 * dhcp.c: Decline messages were not multicast but unicast.
2938 * etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
2939 Do not try hard to insert arbitrary packet's source address,
2940 etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
2941 etharp_query() now always DOES call ETHARP_TRY_HARD so that users
2942 querying an address will see it appear in the cache (DHCP could
2943 suffer from this when a server invalidly gave an in-use address.)
2944 * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
2945 comparing network addresses (identifiers), not the network masks
2946 themselves.
2947 * ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
2948 IP address actually belongs to the network of the given interface.
2949
2950 2004-11-24 Kieran Mansley <[email protected]>
2951 * tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.
2952
2953(STABLE-1_1_0-RC1)
2954
2955 2004-10-16 Kieran Mansley <[email protected]>
2956 * tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
2957 even if one is already pending, if the rcv_wnd is above a threshold
2958 (currently TCP_WND/2). This avoids waiting for a timer to expire to send a
2959 delayed ACK in order to open the window if the stack is only receiving data.
2960
2961 2004-09-12 Kieran Mansley <[email protected]>
2962 * tcp*.*: Retransmit time-out handling improvement by Sam Jansen.
2963
2964 2004-08-20 Tony Mountifield <[email protected]>
2965 * etharp.c: Make sure the first pbuf queued on an ARP entry
2966 is properly ref counted.
2967
2968 2004-07-27 Tony Mountifield <[email protected]>
2969 * debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
2970 warnings about comparison.
2971 * pbuf.c: Stopped compiler complaining of empty if statement
2972 when LWIP_DEBUGF() empty. Closed an unclosed comment.
2973 * tcp.c: Stopped compiler complaining of empty if statement
2974 when LWIP_DEBUGF() empty.
2975 * ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
2976 * inet.c: Added a couple of casts to quiet the compiler.
2977 No need to test isascii(c) before isdigit(c) or isxdigit(c).
2978
2979 2004-07-22 Tony Mountifield <[email protected]>
2980 * inet.c: Made data types consistent in inet_ntoa().
2981 Added casts for return values of checksum routines, to pacify compiler.
2982 * ip_frag.c, tcp_out.c, sockets.c, pbuf.c
2983 Small corrections to some debugging statements, to pacify compiler.
2984
2985 2004-07-21 Tony Mountifield <[email protected]>
2986 * etharp.c: Removed spurious semicolon and added missing end-of-comment.
2987 * ethernetif.c Updated low_level_output() to match prototype for
2988 netif->linkoutput and changed low_level_input() similarly for consistency.
2989 * api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
2990 of raw_recv() in raw.h and so avoid compiler error.
2991 * sockets.c: Added trivial (int) cast to keep compiler happier.
2992 * ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.
2993
2994(STABLE-1_0_0)
2995
2996 ++ Changes:
2997
2998 2004-07-05 Leon Woestenberg <[email protected]>
2999 * sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure
3000 your cc.h file defines this either 1 or 0. If non-defined,
3001 defaults to 1.
3002 * .c: Added <string.h> and <errno.h> includes where used.
3003 * etharp.c: Made some array indices unsigned.
3004
3005 2004-06-27 Leon Woestenberg <[email protected]>
3006 * netif.*: Added netif_set_up()/down().
3007 * dhcp.c: Changes to restart program flow.
3008
3009 2004-05-07 Leon Woestenberg <[email protected]>
3010 * etharp.c: In find_entry(), instead of a list traversal per candidate, do a
3011 single-pass lookup for different candidates. Should exploit locality.
3012
3013 2004-04-29 Leon Woestenberg <[email protected]>
3014 * tcp*.c: Cleaned up source comment documentation for Doxygen processing.
3015 * opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC.
3016 * etharp.c: update_arp_entry() only adds new ARP entries when adviced to by
3017 the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option.
3018
3019 ++ Bug fixes:
3020
3021 2004-04-27 Leon Woestenberg <[email protected]>
3022 * etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution
3023 suggested by Timmy Brolin. Fix for 32-bit processors that cannot access
3024 non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix
3025 is to prefix the 14-bit Ethernet headers with two padding bytes.
3026
3027 2004-04-23 Leon Woestenberg <[email protected]>
3028 * ip_addr.c: Fix in the ip_addr_isbroadcast() check.
3029 * etharp.c: Fixed the case where the packet that initiates the ARP request
3030 is not queued, and gets lost. Fixed the case where the packets destination
3031 address is already known; we now always queue the packet and perform an ARP
3032 request.
3033
3034(STABLE-0_7_0)
3035
3036 ++ Bug fixes:
3037
3038 * Fixed TCP bug for SYN_SENT to ESTABLISHED state transition.
3039 * Fixed TCP bug in dequeueing of FIN from out of order segment queue.
3040 * Fixed two possible NULL references in rare cases.
3041
3042(STABLE-0_6_6)
3043
3044 ++ Bug fixes:
3045
3046 * Fixed DHCP which did not include the IP address in DECLINE messages.
3047
3048 ++ Changes:
3049
3050 * etharp.c has been hauled over a bit.
3051
3052(STABLE-0_6_5)
3053
3054 ++ Bug fixes:
3055
3056 * Fixed TCP bug induced by bad window resizing with unidirectional TCP traffic.
3057 * Packets sent from ARP queue had invalid source hardware address.
3058
3059 ++ Changes:
3060
3061 * Pass-by ARP requests do now update the cache.
3062
3063 ++ New features:
3064
3065 * No longer dependent on ctype.h.
3066 * New socket options.
3067 * Raw IP pcb support.
3068
3069(STABLE-0_6_4)
3070
3071 ++ Bug fixes:
3072
3073 * Some debug formatters and casts fixed.
3074 * Numereous fixes in PPP.
3075
3076 ++ Changes:
3077
3078 * DEBUGF now is LWIP_DEBUGF
3079 * pbuf_dechain() has been re-enabled.
3080 * Mentioned the changed use of CVS branches in README.
3081
3082(STABLE-0_6_3)
3083
3084 ++ Bug fixes:
3085
3086 * Fixed pool pbuf memory leak in pbuf_alloc().
3087 Occured if not enough PBUF_POOL pbufs for a packet pbuf chain.
3088 Reported by Savin Zlobec.
3089
3090 * PBUF_POOL chains had their tot_len field not set for non-first
3091 pbufs. Fixed in pbuf_alloc().
3092
3093 ++ New features:
3094
3095 * Added PPP stack contributed by Marc Boucher
3096
3097 ++ Changes:
3098
3099 * Now drops short packets for ICMP/UDP/TCP protocols. More robust.
3100
3101 * ARP queueuing now queues the latest packet instead of the first.
3102 This is the RFC recommended behaviour, but can be overridden in
3103 lwipopts.h.
3104
3105(0.6.2)
3106
3107 ++ Bugfixes:
3108
3109 * TCP has been fixed to deal with the new use of the pbuf->ref
3110 counter.
3111
3112 * DHCP dhcp_inform() crash bug fixed.
3113
3114 ++ Changes:
3115
3116 * Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
3117 pbuf_refresh(). This has sped up pbuf pool operations considerably.
3118 Implemented by David Haas.
3119
3120(0.6.1)
3121
3122 ++ New features:
3123
3124 * The packet buffer implementation has been enhanced to support
3125 zero-copy and copy-on-demand for packet buffers which have their
3126 payloads in application-managed memory.
3127 Implemented by David Haas.
3128
3129 Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
3130 if an outgoing packet can be directly sent on the link, or perform
3131 a copy-on-demand when necessary.
3132
3133 The application can safely assume the packet is sent, and the RAM
3134 is available to the application directly after calling udp_send()
3135 or similar function.
3136
3137 ++ Bugfixes:
3138
3139 * ARP_QUEUEING should now correctly work for all cases, including
3140 PBUF_REF.
3141 Implemented by Leon Woestenberg.
3142
3143 ++ Changes:
3144
3145 * IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
3146 to a '0.0.0.0' IP address.
3147
3148 * The packet buffer implementation is changed. The pbuf->ref counter
3149 meaning has changed, and several pbuf functions have been
3150 adapted accordingly.
3151
3152 * netif drivers have to be changed to set the hardware address length field
3153 that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).
3154 See the contrib/ports/c16x cs8900 driver as a driver example.
3155
3156 * netif's have a dhcp field that must be initialized to NULL by the driver.
3157 See the contrib/ports/c16x cs8900 driver as a driver example.
3158
3159(0.5.x) This file has been unmaintained up to 0.6.1. All changes are
3160 logged in CVS but have not been explained here.
3161
3162(0.5.3) Changes since version 0.5.2
3163
3164 ++ Bugfixes:
3165
3166 * memp_malloc(MEMP_API_MSG) could fail with multiple application
3167 threads because it wasn't protected by semaphores.
3168
3169 ++ Other changes:
3170
3171 * struct ip_addr now packed.
3172
3173 * The name of the time variable in arp.c has been changed to ctime
3174 to avoid conflicts with the time() function.
3175
3176(0.5.2) Changes since version 0.5.1
3177
3178 ++ New features:
3179
3180 * A new TCP function, tcp_tmr(), now handles both TCP timers.
3181
3182 ++ Bugfixes:
3183
3184 * A bug in tcp_parseopt() could cause the stack to hang because of a
3185 malformed TCP option.
3186
3187 * The address of new connections in the accept() function in the BSD
3188 socket library was not handled correctly.
3189
3190 * pbuf_dechain() did not update the ->tot_len field of the tail.
3191
3192 * Aborted TCP connections were not handled correctly in all
3193 situations.
3194
3195 ++ Other changes:
3196
3197 * All protocol header structs are now packed.
3198
3199 * The ->len field in the tcp_seg structure now counts the actual
3200 amount of data, and does not add one for SYN and FIN segments.
3201
3202(0.5.1) Changes since version 0.5.0
3203
3204 ++ New features:
3205
3206 * Possible to run as a user process under Linux.
3207
3208 * Preliminary support for cross platform packed structs.
3209
3210 * ARP timer now implemented.
3211
3212 ++ Bugfixes:
3213
3214 * TCP output queue length was badly initialized when opening
3215 connections.
3216
3217 * TCP delayed ACKs were not sent correctly.
3218
3219 * Explicit initialization of BSS segment variables.
3220
3221 * read() in BSD socket library could drop data.
3222
3223 * Problems with memory alignment.
3224
3225 * Situations when all TCP buffers were used could lead to
3226 starvation.
3227
3228 * TCP MSS option wasn't parsed correctly.
3229
3230 * Problems with UDP checksum calculation.
3231
3232 * IP multicast address tests had endianess problems.
3233
3234 * ARP requests had wrong destination hardware address.
3235
3236 ++ Other changes:
3237
3238 * struct eth_addr changed from u16_t[3] array to u8_t[6].
3239
3240 * A ->linkoutput() member was added to struct netif.
3241
3242 * TCP and UDP ->dest_* struct members where changed to ->remote_*.
3243
3244 * ntoh* macros are now null definitions for big endian CPUs.
3245
3246(0.5.0) Changes since version 0.4.2
3247
3248 ++ New features:
3249
3250 * Redesigned operating system emulation layer to make porting easier.
3251
3252 * Better control over TCP output buffers.
3253
3254 * Documenation added.

3284 ++ Other changes:
3285
3286 * Variables named "data" and "code" have been renamed in order to
3287 avoid name conflicts in certain compilers.
3288
3289 * Variable++ have in appliciable cases been translated to ++variable
3290 since some compilers generate better code in the latter case.
3291
3292(0.4.1) Changes since version 0.4
3293
3294 ++ New features:
3295
3296 * TCP: Connection attempts time out earlier than data
3297 transmissions. Nagle algorithm implemented. Push flag set on the
3298 last segment in a burst.
3299
3300 * UDP: experimental support for UDP-Lite extensions.
3301
3302 ++ Bugfixes:
3303
3304 * TCP: out of order segments were in some cases handled incorrectly,
3305 and this has now been fixed. Delayed acknowledgements was broken
3306 in 0.4, has now been fixed. Binding to an address that is in use
3307 now results in an error. Reset connections sometimes hung an
3308 application; this has been fixed.
3309
3310 * Checksum calculation sometimes failed for chained pbufs with odd
3311 lengths. This has been fixed.
3312
3313 * API: a lot of bug fixes in the API. The UDP API has been improved
3314 and tested. Error reporting and handling has been
3315 improved. Logical flaws and race conditions for incoming TCP
3316 connections has been found and removed.
3317
3318 * Memory manager: alignment issues. Reallocating memory sometimes
3319 failed, this has been fixed.
3320
3321 * Generic library: bcopy was flawed and has been fixed.
3322
3323 ++ Other changes:
3324
3325 * API: all datatypes has been changed from generic ones such as
3326 ints, to specified ones such as u16_t. Functions that return
3327 errors now have the correct type (err_t).
3328
3329 * General: A lot of code cleaned up and debugging code removed. Many
3330 portability issues have been fixed.
3331
3332 * The license was changed; the advertising clause was removed.
3333
3334 * C64 port added.
3335
3336 * Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri
3337 Kosunen, Mikael Caleres, and Frits Wilmink for reporting and
3338 fixing bugs!
3339
3340(0.4) Changes since version 0.3.1
3341
3342 * Memory management has been radically changed; instead of
3343 allocating memory from a shared heap, memory for objects that are
3344 rapidly allocated and deallocated is now kept in pools. Allocation
3345 and deallocation from those memory pools is very fast. The shared
3346 heap is still present but is used less frequently.
3347
3348 * The memory, memory pool, and packet buffer subsystems now support
3349 4-, 2-, or 1-byte alignment.
3350
3351 * "Out of memory" situations are handled in a more robust way.
3352
3353 * Stack usage has been reduced.
3354
3355 * Easier configuration of lwIP parameters such as memory usage,
3356 TTLs, statistics gathering, etc. All configuration parameters are
3357 now kept in a single header file "lwipopts.h".
3358
3359 * The directory structure has been changed slightly so that all
3360 architecture specific files are kept under the src/arch
3361 hierarchy.
3362
3363 * Error propagation has been improved, both in the protocol modules
3364 and in the API.
3365
3366 * The code for the RTXC architecture has been implemented, tested
3367 and put to use.
3368
3369 * Bugs have been found and corrected in the TCP, UDP, IP, API, and
3370 the Internet checksum modules.
3371
3372 * Bugs related to porting between a 32-bit and a 16-bit architecture
3373 have been found and corrected.
3374
3375 * The license has been changed slightly to conform more with the
3376 original BSD license, including the advertisement clause.
3377
3378(0.3.1) Changes since version 0.3
3379
3380 * Fix of a fatal bug in the buffer management. Pbufs with allocated
3381 RAM never returned the RAM when the pbuf was deallocated.
3382
3383 * TCP congestion control, window updates and retransmissions did not
3384 work correctly. This has now been fixed.
3385
3386 * Bugfixes in the API.
3387
3388(0.3) Changes since version 0.2
3389
3390 * New and improved directory structure. All include files are now
3391 kept in a dedicated include/ directory.
3392
3393 * The API now has proper error handling. A new function,
3394 netconn_err(), now returns an error code for the connection in
3395 case of errors.
3396
3397 * Improvements in the memory management subsystem. The system now
3398 keeps a pointer to the lowest free memory block. A new function,
3399 mem_malloc2() tries to allocate memory once, and if it fails tries
3400 to free some memory and retry the allocation.
3401
3402 * Much testing has been done with limited memory
3403 configurations. lwIP now does a better job when overloaded.
3404
3405 * Some bugfixes and improvements to the buffer (pbuf) subsystem.
3406
3407 * Many bugfixes in the TCP code:
3408
3409 - Fixed a bug in tcp_close().
3410
3411 - The TCP receive window was incorrectly closed when out of
3412 sequence segments was received. This has been fixed.
3413
3414 - Connections are now timed-out of the FIN-WAIT-2 state.
3415
3416 - The initial congestion window could in some cases be too
3417 large. This has been fixed.
3418
3419 - The retransmission queue could in some cases be screwed up. This
3420 has been fixed.
3421
3422 - TCP RST flag now handled correctly.
3423
3424 - Out of sequence data was in some cases never delivered to the
3425 application. This has been fixed.
3426
3427 - Retransmitted segments now contain the correct acknowledgment
3428 number and advertised window.
3429
3430 - TCP retransmission timeout backoffs are not correctly computed
3431 (ala BSD). After a number of retransmissions, TCP now gives up
3432 the connection.
3433
3434 * TCP connections now are kept on three lists, one for active
3435 connections, one for listening connections, and one for
3436 connections that are in TIME-WAIT. This greatly speeds up the fast
3437 timeout processing for sending delayed ACKs.
3438
3439 * TCP now provides proper feedback to the application when a
3440 connection has been successfully set up.
3441
3442 * More comments have been added to the code. The code has also been
3443 somewhat cleaned up.
3444
3445(0.2) Initial public release.
