18
19 2012-03-25: Simon Goldschmidt (idea by Mason)
20 * posix/*: added posix-compatibility include files posix/netdb.h and posix/sys/socket.h
21 which are a simple wrapper to the correct lwIP include files.
22
23 2012-01-16: Simon Goldschmidt
24 * opt.h, icmp.c: Added option CHECKSUM_GEN_ICMP
25
26 2011-12-17: Simon Goldschmidt
27 * ip.h: implemented API functions to access so_options of IP pcbs (UDP, TCP, RAW)
28 (fixes bug #35061)
29
30 2011-09-27: Simon Goldschmidt
31 * opt.h, tcp.c, tcp_in.c: Implemented limiting data on ooseq queue (task #9989)
32 (define TCP_OOSEQ_MAX_BYTES / TCP_OOSEQ_MAX_PBUFS in lwipopts.h)
33
34 2011-09-21: Simon Goldschmidt
35 * opt.h, api.h, api_lib.c, api_msg.h/.c, sockets.c: Implemented timeout on

37
38 2011-09-21: Simon Goldschmidt
39 * init.c: Converted runtime-sanity-checks into compile-time checks that can
40 be disabled (since runtime checks can often not be seen on embedded targets)
41
42 2011-09-11: Simon Goldschmidt
43 * ppp.h, ppp_impl.h: splitted ppp.h to an internal and external header file
44 to get a clear separation of which functions an application or port may use
45 (task #11281)
46
47 2011-09-11: Simon Goldschmidt
48 * opt.h, tcp_impl.h, tcp.c, udp.h/.c: Added a config option to randomize
49 initial local TCP/UDP ports (so that different port ranges are used after
50 a reboot; bug #33818; this one added tcp_init/udp_init functions again)
51
52 2011-09-03: Simon Goldschmidt
53 * dhcp.c: DHCP uses LWIP_RAND() for xid's (bug #30302)
54
55 2011-08-24: Simon Goldschmidt
56 * opt.h, netif.h/.c: added netif remove callback (bug #32397)
57
58 2011-07-26: Simon Goldschmidt
59 * etharp.c: ETHARP_SUPPORT_VLAN: add support for an external VLAN filter
60 function instead of only checking for one VLAN (define ETHARP_VLAN_CHECK_FN)
61
62 2011-07-21: Simon Goldschmidt (patch by hanhui)
63 * ip4.c, etharp.c, pbuf.h: bug #33634 ip_forward() have a faulty behaviour:
64 Added pbuf flags to mark incoming packets as link-layer broadcast/multicast.
65 Also added code to allow ip_forward() to forward non-broadcast packets to
66 the input netif (set IP_FORWARD_ALLOW_TX_ON_RX_NETIF==1).
67
68 2011-06-26: Simon Goldschmidt (patch by Cameron Gutman)
69 * tcp.c, tcp_out.c: bug #33604: added some more asserts to check that
70 pcb->state != LISTEN
71
72 2011-05-14: Simon Goldschmidt (patch by Stéphane Lesage)

283 lwip_send() sends as much as possible for non-blocking sockets
284
285 2011-07-22: Simon Goldschmidt
286 * pbuf.c/.h, timers.c: freeing ooseq pbufs when the pbuf pool is empty implemented
287 for NO_SYS==1: when not using sys_check_timeouts(), call PBUF_CHECK_FREE_OOSEQ()

289
290 2011-07-21: Simon Goldschmidt
291 * etharp.c: fixed bug #33551 (ARP entries may time out although in use) by

317
318 2011-03-27: Simon Goldschmidt
319 * tcp_impl.h, tcp_in.c, tcp_out.c: Removed 'dataptr' from 'struct tcp_seg' and

323 * dhcp.c/.h: Added a function to deallocate the struct dhcp from a netif
324 (fixes bug #31525).
325
326 2010-07-12: Simon Goldschmidt (patch by Stephane Lesage)
327 * ip.c, udp.c/.h, pbuf.h, sockets.c: task #10495: Added support for
328 IP_MULTICAST_LOOP at socket- and raw-API level.
329
330 2010-06-16: Simon Goldschmidt
331 * ip.c: Added an optional define (LWIP_IP_ACCEPT_UDP_PORT) that can allow
332 link-layer-addressed UDP traffic to be received while a netif is down (just
333 like DHCP during configuration)
334
335 2010-05-22: Simon Goldschmidt
336 * many many files: bug #27352: removed packing from ip_addr_t, the packed
337 version is now only used in protocol headers. Added global storage for
338 current src/dest IP address while in input functions.
339
340 2010-05-16: Simon Goldschmidt
341 * def.h: task #10391: Add preprocessor-macros for compile-time htonl
342 calculation (and use them throughout the stack where applicable)
343
344 2010-05-16: Simon Goldschmidt
345 * opt.h, memp_std.h, memp.c, ppp_oe.h/.c: PPPoE now uses its own MEMP pool
346 instead of the heap (moved struct pppoe_softc from ppp_oe.c to ppp_oe.h)
347
348 2010-05-16: Simon Goldschmidt
349 * opt.h, memp_std.h, dns.h/.c: DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses its own
350 MEMP pool instead of the heap
351
352 2010-05-13: Simon Goldschmidt
353 * tcp.c, udp.c: task #6995: Implement SO_REUSEADDR (correctly), added
354 new option SO_REUSE_RXTOALL to pass received UDP broadcast/multicast
355 packets to more than one pcb.
356
357 2010-05-02: Simon Goldschmidt
358 * netbuf.h/.c, sockets.c, api_msg.c: use checksum-on-copy for sending
359 UDP data for LWIP_NETIF_TX_SINGLE_PBUF==1
360
361 2010-04-30: Simon Goldschmidt
362 * udp.h/.c, pbuf.h/.c: task #6849: added udp_send(_to/_if) functions that
363 take a precalculated checksum, added pbuf_fill_chksum() to copy data
364 into a pbuf and at the same time calculating the checksum for that data
365
366 2010-04-29: Simon Goldschmidt
367 * ip_addr.h, etharp.h/.c, autoip.c: Create overridable macros for copying
368 2-byte-aligned IP addresses and MAC addresses
369

372
373 2010-04-14: Simon Goldschmidt
374 * tcpip.h/.c, timers.c: Added an overridable define to get informed when the
375 tcpip_thread processes messages or timeouts to implement a watchdog.
376
377 2010-03-28: Simon Goldschmidt
378 * ip_frag.c: create a new (contiguous) PBUF_RAM for every outgoing
379 fragment if LWIP_NETIF_TX_SINGLE_PBUF==1
380
381 2010-03-27: Simon Goldschmidt
382 * etharp.c: Speedup TX by moving code from find_entry to etharp_output/
383 etharp_query to prevent unnecessary function calls (inspired by
384 patch #7135).
385
386 2010-03-20: Simon Goldschmidt
387 * opt.h, tcpip.c/.h: Added an option to disable tcpip_(un)timeout code
388 since the linker cannot do this automatically to save space.
389
390 2010-03-20: Simon Goldschmidt
391 * opt.h, etharp.c/.h: Added support for static ARP table entries
392
393 2010-03-14: Simon Goldschmidt
394 * tcp_impl.h, tcp_out.c, inet_chksum.h/.c: task #6849: Calculate checksum
395 when creating TCP segments, not when (re-)transmitting them.
396
397 2010-03-07: Simon Goldschmidt
398 * sockets.c: bug #28775 (select/event_callback: only check select_cb_list
399 on change) plus use SYS_LIGHTWEIGHT_PROT to protect the select code.
400 This should speed up receiving data on sockets as the select code in
401 event_callback is only executed when select is waiting.
402
403 2010-03-06: Simon Goldschmidt
404 * tcp_out.c: task #7013 (Create option to have all packets delivered to
405 netif->output in one piece): Always copy to try to create single pbufs
406 in tcp_write.
407
408 2010-03-06: Simon Goldschmidt
409 * api.h, api_lib.c, sockets.c: task #10167 (sockets: speed up TCP recv
410 by not allocating a netbuf): added function netconn_recv_tcp_pbuf()
411 for tcp netconns to receive pbufs, not netbufs; use that function
412 for tcp sockets.
413
414 2010-03-05: Jakob Ole Stoklundsen / Simon Goldschmidt
415 * opt.h, tcp.h, tcp_impl.h, tcp.c, tcp_in.c, tcp_out.c: task #7040:
416 Work on tcp_enqueue: Don't waste memory when chaining segments,
417 added option TCP_OVERSIZE to prevent creating many small pbufs when
418 calling tcp_write with many small blocks of data. Instead, pbufs are
419 allocated larger than needed and the space is used for later calls to
420 tcp_write.
421
422 2010-02-21: Simon Goldschmidt
423 * stats.c/.h: Added const char* name to mem- and memp-stats for easier
424 debugging.
425
426 2010-02-21: Simon Goldschmidt
427 * tcp.h (and usages), added tcp_impl.h: Splitted API and internal
428 implementation of tcp to make API usage cleare to application programmers
429
430 2010-02-14: Simon Goldschmidt/Stephane Lesage
431 * ip_addr.h: Improved some defines working on ip addresses, added faster
432 macro to copy addresses that cannot be NULL
433
434 2010-02-13: Simon Goldschmidt
435 * api.h, api_lib.c, api_msg.c, sockets.c: task #7865 (implement non-
436 blocking send operation)
437
438 2010-02-12: Simon Goldschmidt
439 * sockets.c/.h: Added a minimal version of posix fctl() to have a
440 standardised way to set O_NONBLOCK for nonblocking sockets.
441
442 2010-02-12: Simon Goldschmidt
443 * dhcp.c/.h, autoip.c/.h: task #10139 (Prefer statically allocated
444 memory): added autoip_set_struct() and dhcp_set_struct() to let autoip
445 and dhcp work with user-allocated structs instead of callin mem_malloc
446
447 2010-02-12: Simon Goldschmidt/Jeff Barber
448 * tcp.c/h: patch #6865 (SO_REUSEADDR for TCP): if pcb.so_options has
449 SOF_REUSEADDR set, allow binding to endpoint in TIME_WAIT
450
451 2010-02-12: Simon Goldschmidt
452 * sys layer: task #10139 (Prefer statically allocated memory): converted
453 mbox and semaphore functions to take pointers to sys_mbox_t/sys_sem_t;
454 converted sys_mbox_new/sys_sem_new to take pointers and return err_t;
455 task #7212: Add Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX
456 to let sys.h use binary semaphores instead of mutexes - as before)
457
458 2010-02-09: Simon Goldschmidt (Simon Kallweit)
459 * timers.c/.h: Added function sys_restart_timeouts() from patch #7085
460 (Restart system timeout handling)
461
462 2010-02-09: Simon Goldschmidt
463 * netif.c/.h, removed loopif.c/.h: task #10153 (Integrate loopif into
464 netif.c) - loopif does not have to be created by the port any more,
465 just define LWIP_HAVE_LOOPIF to 1.
466
467 2010-02-08: Simon Goldschmidt
468 * inet.h, ip_addr.c/.h: Added reentrant versions of inet_ntoa/ipaddr_ntoa
469 inet_ntoa_r/ipaddr_ntoa_r
470
471 2010-02-08: Simon Goldschmidt

475 * netif.h: Added function-like macros to get/set the hostname on a netif
476
477 2010-02-04: Simon Goldschmidt
478 * nearly every file: Replaced struct ip_addr by typedef ip_addr_t to
479 make changing the actual implementation behind the typedef easier.
480
481 2010-02-01: Simon Goldschmidt
482 * opt.h, memp_std.h, dns.h, netdb.c, memp.c: Let netdb use a memp pool
483 for allocating memory when getaddrinfo() is called.
484
485 2010-01-31: Simon Goldschmidt
486 * dhcp.h, dhcp.c: Reworked the code that parses DHCP options: parse
487 them once instead of parsing for every option. This also removes
488 the need for mem_malloc from dhcp_recv and makes it possible to
489 correctly retrieve the BOOTP file.
490
491 2010-01-30: simon Goldschmidt
492 * sockets.c: Use SYS_LIGHTWEIGHT_PROT instead of a semaphore to protect
493 the sockets array.

501 Add non-blocking support for connect (partly from patch #6860),
502 plus many cleanups in socket & netconn API.
503
504 2010-01-27: Simon Goldschmidt
505 * opt.h, tcp.h, init.c, api_msg.c: Added TCP_SNDQUEUELOWAT corresponding
506 to TCP_SNDLOWAT and added tcp_sndqueuelen() - this fixes bug #28605
507
508 2010-01-26: Simon Goldschmidt
509 * snmp: Use memp pools for snmp instead of the heap; added 4 new pools.
510
511 2010-01-14: Simon Goldschmidt
512 * ppp.c/.h: Fixed bug #27856: PPP: Set netif link- and status-callback
513 by adding ppp_set_netif_statuscallback()/ppp_set_netif_linkcallback()
514
515 2010-01-13: Simon Goldschmidt
516 * mem.c: The heap now may be moved to user-defined memory by defining
517 LWIP_RAM_HEAP_POINTER as a void pointer to that memory's address
518 (patch #6966 and bug #26133)
519
520 2010-01-10: Simon Goldschmidt (Bill Auerbach)

526 LWIP_RAND() for lwip-wide randomization (to be defined in cc.h)
527
528 2009-12-31: Simon Goldschmidt
529 * tcpip.c, init.c, memp.c, sys.c, memp_std.h, sys.h, tcpip.h
530 added timers.c/.h: Separated timer implementation from semaphore/mbox
531 implementation, moved timer implementation to timers.c/.h, timers are
532 now only called from tcpip_thread or by explicitly checking them.
533 (TASK#7235)
534
535 2009-12-27: Simon Goldschmidt
536 * opt.h, etharp.h/.c, init.c, tcpip.c: Added an additional option
537 LWIP_ETHERNET to support ethernet without ARP (necessary for pure PPPoE)
538
539
540 ++ Bugfixes:

551
552 2011-03-27: Simon Goldschmidt
553 * tcp.c: Fixed bug #32926 (TCP_RMV(&tcp_bound_pcbs) is called on unbound tcp
554 pcbs) by checking if the pcb was bound (local_port != 0).
555
556 2011-03-27: Simon Goldschmidt

562
563 2011-03-27: Simon Goldschmidt
564 * tcp_out.c: Fixed bug #32820 (Outgoing TCP connections created before route

566 route.
567
568 2011-03-22: Simon Goldschmidt

571
572 2011-03-14: Simon Goldschmidt
573 * err.h/.c, sockets.c, api_msg.c: fixed bug #31748 (Calling non-blocking connect
574 more than once can render a socket useless) since it mainly involves changing
575 "FATAL" classification of error codes: ERR_USE and ERR_ISCONN just aren't fatal.
576
577 2011-03-13: Simon Goldschmidt
578 * sockets.c: fixed bug #32769 (ESHUTDOWN is linux-specific) by fixing
579 err_to_errno_table (ERR_CLSD: ENOTCONN instead of ESHUTDOWN), ERR_ISCONN:
580 use EALRADY instead of -1
581
582 2011-03-13: Simon Goldschmidt
583 * api_lib.c: netconn_accept: return ERR_ABRT instead of ERR_CLSD if the
584 connection has been aborted by err_tcp (since this is not a normal closing
585 procedure).
586
587 2011-03-13: Simon Goldschmidt
588 * tcp.c: tcp_bind: return ERR_VAL instead of ERR_ISCONN when trying to bind
589 with pcb->state != CLOSED

603
604 2010-11-23: Simon Goldschmidt

618 after a successful nonblocking connection.
619
620 2010-11-22: Simon Goldschmidt
621 * etharp.c: Fixed bug #31722: IP packets sent with an AutoIP source addr
622 must be sent link-local
623
624 2010-11-22: Simon Goldschmidt
625 * timers.c: patch #7329: tcp_timer_needed prototype was ifdef'ed out for

637 no-copy TCP writes will never succeed.
638
639 2010-11-20: Simon Goldschmidt
640 * dns.c: Fixed bug #31701: Error return value from dns_gethostbyname() does
641 not match documentation: return ERR_ARG instead of ERR_VAL if not
642 initialized or wrong argument.
643
644 2010-10-20: Simon Goldschmidt
645 * sockets.h: Fixed bug #31385: sizeof(struct sockaddr) is 30 but should be 16
646
647 2010-10-05: Simon Goldschmidt
648 * dhcp.c: Once again fixed #30038: DHCP/AutoIP cooperation failed when
649 replugging the network cable after an AutoIP address was assigned.
650
651 2010-08-10: Simon Goldschmidt
652 * tcp.c: Fixed bug #30728: tcp_new_port() did not check listen pcbs
653
654 2010-08-03: Simon Goldschmidt

663 disabled.
664
665 2010-07-27: Simon Goldschmidt

694 2010-06-21: Simon Goldschmidt
695 * pbuf.c/.h, ip_frag.c/.h, opt.h, memp_std.h: Fixed bug #29361 (ip_frag has
696 problems with zero-copy DMA MACs) by adding custom pbufs and implementing
697 custom pbufs that reference other (original) pbufs. Additionally set
698 IP_FRAG_USES_STATIC_BUF=0 as default to be on the safe side.
699
700 2010-06-15: Simon Goldschmidt
701 * dhcp.c: Fixed bug #29970: DHCP endian issue parsing option responses
702

712
713 2010-05-16: Simon Goldschmidt

733
734 2010-03-26: Simon Goldschmidt
735 * various files: Fixed compiling with different options disabled (TCP/UDP),

754 and basing PBUF_LINK_HLEN on it.
755
756 2010-03-08: Simon Goldschmidt
757 * netif.c, ipv4/ip.c: task #10241 (AutoIP: don't break existing connections

760 addresses.
761
762 2010-03-06: Simon Goldschmidt
763 * sockets.c: Fixed LWIP_NETIF_TX_SINGLE_PBUF for LWIP_TCPIP_CORE_LOCKING

783
784 2010-02-20: Simon Goldschmidt
785 * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Task #10088: Correctly implement
786 close() vs. shutdown(). Now the application does not get any more

788
789 2010-02-19: Simon Goldschmidt
790 * mem.c/.h, pbuf.c: Renamed mem_realloc() to mem_trim() to prevent
791 confusion with realloc()
792
793 2010-02-15: Simon Goldschmidt/Stephane Lesage

800 admin-status of a netif are up
801
802 2010-02-14: Simon Goldschmidt
803 * opt.h: Disable ETHARP_TRUST_IP_MAC by default since it slows down packet
804 reception and is not really necessary
805
806 2010-02-14: Simon Goldschmidt
807 * etharp.c/.h: Fixed ARP input processing: only add a new entry if a
808 request was directed as us (RFC 826, Packet Reception), otherwise
809 only update existing entries; internalized some functions
810
811 2010-02-14: Simon Goldschmidt
812 * netif.h, etharp.c, tcpip.c: Fixed bug #28183 (ARP and TCP/IP cannot be
813 disabled on netif used for PPPoE) by adding a new netif flag
814 (NETIF_FLAG_ETHERNET) that tells the stack the device is an ethernet
815 device but prevents usage of ARP (so that ethernet_input can be used
816 for PPPoE).
817
818 2010-02-12: Simon Goldschmidt
819 * netif.c: netif_set_link_up/down: only do something if the link state
820 actually changes
821
822 2010-02-12: Simon Goldschmidt/Stephane Lesage
823 * api_msg.c: Fixed bug #28865 (Cannot close socket/netconn in non-blocking

828
829 2010-02-09: Simon Goldschmidt
830 * api_lib.c, api_msg.c, sockets.c, api.h, api_msg.h: Fixed bug #22110

832 application)
833
834 2010-02-09: Simon Goldschmidt/Stephane Lesage
835 * sockets.c: Fixed bug #28853 (lwip_recvfrom() returns 0 on receive time-out
836 or any netconn_recv() error)
837
838 2010-02-09: Simon Goldschmidt
839 * ppp.c: task #10154 (PPP: Update snmp in/out counters for tx/rx packets)
840
841 2010-02-09: Simon Goldschmidt
842 * netif.c: For loopback packets, adjust the stats- and snmp-counters
843 for the loopback netif.
844
845 2010-02-08: Simon Goldschmidt
846 * igmp.c/.h, ip.h: Moved most defines from igmp.h to igmp.c for clarity
847 since they are not used anywhere else.
848
849 2010-02-08: Simon Goldschmidt (Stéphane Lesage)
850 * igmp.c, igmp.h, stats.c, stats.h: Improved IGMP stats
851 (patch from bug #28798)
852
853 2010-02-08: Simon Goldschmidt (Stéphane Lesage)
854 * igmp.c: Fixed bug #28798 (Error in "Max Response Time" processing) and
855 another bug when LWIP_RAND() returns zero.
856
857 2010-02-04: Simon Goldschmidt
858 * nearly every file: Use macros defined in ip_addr.h (some of them new)
859 to work with IP addresses (preparation for bug #27352 - Change ip_addr
860 from struct to typedef (u32_t) - and better code).
861
862 2010-01-31: Simon Goldschmidt
863 * netif.c: Don't call the link-callback from netif_set_up/down() since
864 this invalidly retriggers DHCP.

866 2010-01-29: Simon Goldschmidt
867 * ip_addr.h, inet.h, def.h, inet.c, def.c, more: Cleanly separate the
868 portability file inet.h and its contents from the stack: moved htonX-
869 functions to def.h (and the new def.c - they are not ipv4 dependent),
870 let inet.h depend on ip_addr.h and not the other way round.
871 This fixes bug #28732.
872

879 ERR_ABRT means the application has called tcp_abort()!
880
881 2010-01-25: Simon Goldschmidt
882 * snmp_structs.h, msg_in.c: Partly fixed bug #22070 (MIB_OBJECT_WRITE_ONLY

884 returned by getnext (though not by get)
885
886 2010-01-24: Simon Goldschmidt
887 * snmp: Renamed the private mib node from 'private' to 'mib_private' to

1067 testing for valid reply
1068
1069 2009-10-19: Simon Goldschmidt
1070 * dhcp.c: Removed most calls to udp_connect since they aren't necessary

1176 of the pool allocator (can save code size with MEM_LIBC_MALLOC if libc-malloc
1177 is otherwise used)
1178
1179 2009-01-28 Jonathan Larmour (suggested by Bill Bauerbach)
1180 * ipv4/inet_chksum.c, ipv4/lwip/inet_chksum.h: inet_chksum_pseudo_partial()

1193 * mem.c, opt.h, stats.h: fixed bug #21433: Calling mem_free/pbuf_free from
1194 interrupt context isn't safe: LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT allows
1195 mem_free to run between mem_malloc iterations. Added illegal counter for
1196 mem stats.
1197
1198 2008-06-27 Simon Goldschmidt

1213 modified version of patch # 6370: Moved loopif code to netif.c so that
1214 loopback traffic is supported on all netifs (all local IPs).

1287
1288 2009-04-29 Frédéric Bernon
1289 * raw.c, udp.c, init.c, opt.h, ip.h, sockets.h: bug #26309: Implement the
1290 SO(F)_BROADCAST filter for all API layers. Avoid the unindented reception
1291 of broadcast packets even when this option wasn't set. Port maintainers
1292 which want to enable this filter have to set IP_SOF_BROADCAST=1 in opt.h.
1293 If you want this option also filter broadcast on recv operations, you also
1294 have to set IP_SOF_BROADCAST_RECV=1 in opt.h.
1295
1296 2009-04-28 Simon Goldschmidt, Jakob Stoklund Olesen

1301 * tcp_out.c: bug #24212: Deadlocked tcp_retransmit due to exceeded pcb->cwnd
1302 Fixed by sorting the unsent and unacked queues (segments are inserted at the
1303 right place in tcp_output and tcp_rexmit).
1304
1305 2009-04-25 Simon Goldschmidt
1306 * memp.c, mem.c, memp.h, mem_std.h: bug #26213 "Problem with memory allocation
1307 when debugging": memp_sizes contained the wrong sizes (including sanity
1308 regions); memp pools for MEM_USE_POOLS were too small
1309
1310 2009-04-24 Simon Goldschmidt, Frédéric Bernon
1311 * inet.c: patch #6765: Fix a small problem with the last changes (incorrect

1313 end of line)
1314
1315 2009-04-19 Simon Goldschmidt
1316 * rawapi.txt: Fixed bug #26069: Corrected documentation: if tcp_connect fails,
1317 pcb->err is called, not pcb->connected (with an error code).
1318
1319 2009-04-19 Simon Goldschmidt
1320 * tcp_out.c: Fixed bug #26236: "TCP options (timestamp) don't work with

1322
1323 2009-04-19 Simon Goldschmidt
1324 * tcp_out.c: Fixed bug #25094: "Zero-length pbuf" (options are now allocated

1387 too small depending on MEM_ALIGNMENT
1388
1389 2009-02-16 Simon Goldschmidt
1390 * sockets.h/.c, api_*.h/.c: fixed arguments of socket functions to match the standard;

1407
1408 2009-02-10 Simon Goldschmidt
1409 * tcp.c: fixed bug #25467: Listen backlog is not reset on timeout in SYN_RCVD:

1411 in state SYN_RCVD is close.
1412
1413 2009-01-28 Jonathan Larmour
1414 * pbuf.c: reclaim pbufs from TCP out-of-sequence segments if we run
1415 out of pool pbufs.
1416
1417 2008-12-19 Simon Goldschmidt
1418 * many files: patch #6699: fixed some warnings on platform where sizeof(int) == 2
1419
1420 2008-12-10 Tamas Somogyi, Frédéric Bernon

1437 padding is included.
1438
1439 2008-09-30 Jonathan Larmour
1440 * sockets.c (lwip_accept): check addr isn't NULL. If it's valid, do an
1441 assertion check that addrlen isn't NULL.
1442
1443 2008-09-30 Jonathan Larmour
1444 * tcp.c: Fix bug #24227, wrong error message in tcp_bind.
1445
1446 2008-08-26 Simon Goldschmidt
1447 * inet.h, ip_addr.h: fixed bug #24132: Cross-dependency between ip_addr.h and

1449
1450 2008-08-14 Simon Goldschmidt
1451 * api_msg.c: fixed bug #23847: do_close_internal references freed memory (when
1452 tcp_close returns != ERR_OK)
1453
1454 2008-07-08 Frédéric Bernon
1455 * stats.h: Fix some build bugs introduced with patch #6483 (missing some parameters
1456 in macros, mainly if MEM_STATS=0 and MEMP_STATS=0).
1457
1458 2008-06-24 Jonathan Larmour
1459 * tcp_in.c: Fix for bug #23693 as suggested by Art R. Ensure cseg is unused
1460 if tcp_seg_copy fails.
1461
1462 2008-06-17 Simon Goldschmidt
1463 * inet_chksum.c: Checked in some ideas of patch #6460 (loop optimizations)
1464 and created defines for swapping bytes and folding u32 to u16.
1465
1466 2008-05-30 Kieran Mansley
1467 * tcp_in.c Remove redundant "if" statement, and use real rcv_wnd
1468 rather than rcv_ann_wnd when deciding if packets are in-window.
1469 Contributed by <arasmussen@consultant.datasys.swri.edu>
1470
1471 2008-05-30 Kieran Mansley
1472 * mem.h: Fix BUG#23254. Change macro definition of mem_* to allow
1473 passing as function pointers when MEM_LIBC_MALLOC is defined.
1474
1475 2008-05-09 Jonathan Larmour
1476 * err.h, err.c, sockets.c: Fix bug #23119: Reorder timeout error code to
1477 stop it being treated as a fatal error.
1478
1479 2008-04-15 Simon Goldschmidt
1480 * dhcp.c: fixed bug #22804: dhcp_stop doesn't clear NETIF_FLAG_DHCP
1481 (flag now cleared)
1482
1483 2008-03-27 Simon Goldschmidt
1484 * mem.c, tcpip.c, tcpip.h, opt.h: fixed bug #21433 (Calling mem_free/pbuf_free
1485 from interrupt context isn't safe): set LWIP_USE_HEAP_FROM_INTERRUPT to 1
1486 in lwipopts.h or use pbuf_free_callback(p)/mem_free_callback(m) to free pbufs
1487 or heap memory from interrupt context
1488
1489 2008-03-26 Simon Goldschmidt
1490 * tcp_in.c, tcp.c: fixed bug #22249: division by zero could occur if a remote
1491 host sent a zero mss as TCP option.
1492
1493
1494(STABLE-1.3.0)
1495
1496 ++ New features:
1497
1498 2008-03-10 Jonathan Larmour
1499 * inet_chksum.c: Allow choice of one of the sample algorithms to be
1500 made from lwipopts.h. Fix comment on how to override LWIP_CHKSUM.
1501
1502 2008-01-22 Frédéric Bernon
1503 * tcp.c, tcp_in.c, tcp.h, opt.h: Rename LWIP_CALCULATE_EFF_SEND_MSS in
1504 TCP_CALCULATE_EFF_SEND_MSS to have coherent TCP options names.
1505
1506 2008-01-14 Frédéric Bernon
1507 * rawapi.txt, api_msg.c, tcp.c, tcp_in.c, tcp.h: changes for task #7675 "Enable
1508 to refuse data on a TCP_EVENT_RECV call". Important, behavior changes for the
1509 tcp_recv callback (see rawapi.txt).
1510
1511 2008-01-14 Frédéric Bernon, Marc Chaland
1512 * ip.c: Integrate patch #6369" ip_input : checking before realloc".
1513
1514 2008-01-12 Frédéric Bernon
1515 * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
1516 netconn::sem per netconn::op_completed like suggested for the task #7490
1517 "Add return value to sys_mbox_post".
1518
1519 2008-01-12 Frédéric Bernon
1520 * api_msg.c, opt.h: replace DEFAULT_RECVMBOX_SIZE per DEFAULT_TCP_RECVMBOX_SIZE,
1521 DEFAULT_UDP_RECVMBOX_SIZE and DEFAULT_RAW_RECVMBOX_SIZE (to optimize queues
1522 sizes), like suggested for the task #7490 "Add return value to sys_mbox_post".
1523
1524 2008-01-10 Frédéric Bernon
1525 * tcpip.h, tcpip.c: add tcpip_callback_with_block function for the task #7490
1526 "Add return value to sys_mbox_post". tcpip_callback is always defined as
1527 "blocking" ("block" parameter = 1).
1528
1529 2008-01-10 Frédéric Bernon
1530 * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
1531 netconn::mbox (sys_mbox_t) per netconn::sem (sys_sem_t) for the task #7490
1532 "Add return value to sys_mbox_post".
1533
1534 2008-01-05 Frédéric Bernon
1535 * sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h, opt.h:
1536 Introduce changes for task #7490 "Add return value to sys_mbox_post" with some
1537 modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which
1538 indicate the number of pointers query by the mailbox. There is three defines
1539 in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the
1540 netconn::acceptmbox. Port maintainers, you can decide to just add this new
1541 parameter in your implementation, but to ignore it to keep the previous behavior.
1542 The new sys_mbox_trypost function return a value to know if the mailbox is
1543 full or if the message is posted. Take a look to sys_arch.txt for more details.
1544 This new function is used in tcpip_input (so, can be called in an interrupt
1545 context since the function is not blocking), and in recv_udp and recv_raw.
1546
1547 2008-01-04 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
1548 * rawapi.txt, api.h, api_lib.c, api_msg.h, api_msg.c, sockets.c, tcp.h, tcp.c,
1549 tcp_in.c, init.c, opt.h: rename backlog options with TCP_ prefix, limit the
1550 "backlog" parameter in an u8_t, 0 is interpreted as "smallest queue", add
1551 documentation in the rawapi.txt file.
1552
1553 2007-12-31 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
1554 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Add TCP persist timer
1555
1556 2007-12-31 Frédéric Bernon, Luca Ceresoli
1557 * autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP packets
1558 in autoip". The change in etharp_raw could be removed, since all calls to
1559 etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be
1560 wrong in the future.
1561
1562 2007-12-30 Frédéric Bernon, Tom Evans
1563 * ip.c: Fix bug #21846 "LwIP doesn't appear to perform any IP Source Address
1564 Filtering" reported by Tom Evans.
1565
1566 2007-12-21 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
1567 * tcp.h, opt.h, api.h, api_msg.h, tcp.c, tcp_in.c, api_lib.c, api_msg.c,
1568 sockets.c, init.c: task #7252: Implement TCP listen backlog: Warning: raw API
1569 applications have to call 'tcp_accepted(pcb)' in their accept callback to
1570 keep accepting new connections.
1571
1572 2007-12-13 Frédéric Bernon
1573 * api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum dns_result"
1574 by err_t type. Add a new err_t code "ERR_INPROGRESS".
1575
1576 2007-12-12 Frédéric Bernon
1577 * dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles
1578 are the one which have ram usage.
1579
1580 2007-12-05 Frédéric Bernon
1581 * netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static
1582 set of variables (=0) or a local one (=1). In this last case, your port should
1583 provide a function "struct hostent* sys_thread_hostent( struct hostent* h)"
1584 which have to do a copy of "h" and return a pointer ont the "per-thread" copy.
1585
1586 2007-12-03 Simon Goldschmidt
1587 * ip.c: ip_input: check if a packet is for inp first before checking all other
1588 netifs on netif_list (speeds up packet receiving in most cases)
1589
1590 2007-11-30 Simon Goldschmidt
1591 * udp.c, raw.c: task #7497: Sort lists (pcb, netif, ...) for faster access
1592 UDP: move a (connected) pcb selected for input to the front of the list of
1593 pcbs so that it is found faster next time. Same for RAW pcbs that have eaten
1594 a packet.
1595
1596 2007-11-28 Simon Goldschmidt
1597 * etharp.c, stats.c, stats.h, opt.h: Introduced ETHARP_STATS
1598
1599 2007-11-25 Simon Goldschmidt
1600 * dhcp.c: dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy
1601 algorithm.
1602
1603 2007-11-24 Simon Goldschmidt
1604 * netdb.h, netdb.c, sockets.h/.c: Moved lwip_gethostbyname from sockets.c
1605 to the new file netdb.c; included lwip_getaddrinfo.
1606
1607 2007-11-21 Simon Goldschmidt
1608 * tcp.h, opt.h, tcp.c, tcp_in.c: implemented calculating the effective send-mss
1609 based on the MTU of the netif used to send. Enabled by default. Disable by
1610 setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21492.
1611
1612 2007-11-19 Frédéric Bernon
1613 * api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name
1614 received match the name query), implement DNS_USES_STATIC_BUF (the place where
1615 copy dns payload to parse the response), return an error if there is no place
1616 for a new query, and fix some minor problems.
1617
1618 2007-11-16 Simon Goldschmidt
1619 * new files: ipv4/inet.c, ipv4/inet_chksum.c, ipv6/inet6.c
1620 removed files: core/inet.c, core/inet6.c
1621 Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into
1622 inet and chksum part; changed includes in all lwIP files as appropriate
1623
1624 2007-11-16 Simon Goldschmidt
1625 * api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential
1626 dns resolver function for netconn api (netconn_gethostbyname) and socket api
1627 (gethostbyname/gethostbyname_r).
1628
1629 2007-11-15 Jim Pettinato, Frédéric Bernon
1630 * opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name
1631 requests with RAW api interface. Initialization is done in lwip_init() with
1632 build time options. DNS timer is added in tcpip_thread context. DHCP can set
1633 DNS server ip addresses when options are received. You need to set LWIP_DNS=1
1634 in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get
1635 some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo"
1636 list with points to improve.
1637
1638 2007-11-06 Simon Goldschmidt
1639 * opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly
1640 enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status
1641 for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.
1642
1643 2007-11-06 Simon Goldschmidt
1644 * api.h, api_msg.h and dependent files: Task #7410: Removed the need to include
1645 core header files in api.h (ip/tcp/udp/raw.h) to hide the internal
1646 implementation from netconn api applications.
1647
1648 2007-11-03 Frédéric Bernon
1649 * api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP &
1650 RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled
1651 by default). Netconn API users can use the netconn_recv_bufsize macro to access
1652 it. This is a first release which have to be improve for TCP. Note it used the
1653 netconn::recv_avail which need to be more "thread-safe" (note there is already
1654 the problem for FIONREAD with lwip_ioctl/ioctlsocket).
1655
1656 2007-11-01 Frédéric Bernon, Marc Chaland
1657 * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c:
1658 Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api
1659 layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api
1660 layer. This option enable to delayed TCP PUSH flag on multiple "write" calls.
1661 Note that previous "copy" parameter for "write" APIs is now called "apiflags".
1662
1663 2007-10-24 Frédéric Bernon
1664 * api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than
1665 TCP_EVENT_xxx macros to get a code more readable. It could also help to remove
1666 some code (like we have talk in "patch #5919 : Create compile switch to remove
1667 select code"), but it could be done later.
1668
1669 2007-10-08 Simon Goldschmidt
1670 * many files: Changed initialization: many init functions are not needed any
1671 more since we now rely on the compiler initializing global and static
1672 variables to zero!
1673
1674 2007-10-06 Simon Goldschmidt
1675 * ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY
1676 to enqueue the received pbufs so that multiple packets can be reassembled
1677 simultaneously and no static reassembly buffer is needed.
1678
1679 2007-10-05 Simon Goldschmidt
1680 * tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so
1681 all netifs (or ports) can use it.
1682
1683 2007-10-05 Frédéric Bernon
1684 * netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the
1685 common function to reduce a little bit the footprint (for all functions using
1686 only the "netif" parameter).
1687
1688 2007-10-03 Frédéric Bernon
1689 * netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down,
1690 netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce
1691 a little bit the footprint (for all functions using only the "netif" parameter).
1692
1693 2007-09-15 Frédéric Bernon
1694 * udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF
1695 option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for
1696 netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for
1697 IP_MULTICAST_TTL and IP_MULTICAST_IF.
1698
1699 2007-09-10 Frédéric Bernon
1700 * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles
1701 even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime()
1702 each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can
1703 decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but
1704 call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime()
1705 or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
1706 This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
1707 snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
1708 when it's queried (any direct call to "sysuptime" is changed by a call to
1709 snmp_get_sysuptime).
1710
1711 2007-09-09 Frédéric Bernon, Bill Florac
1712 * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP,
1713 and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags
1714 if you want IGMP on an interface. igmp_stop() is now called inside netif_remove().
1715 igmp_report_groups() is now called inside netif_set_link_up() (need to have
1716 LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait
1717 the next query message to receive the matching multicast streams).
1718
1719 2007-09-08 Frédéric Bernon
1720 * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains
1721 IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change).
1722 Use this new field to access to common pcb fields (ttl, tos, so_options, etc...).
1723 Enable to access to these fields with LWIP_TCP=0.
1724
1725 2007-09-05 Frédéric Bernon
1726 * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h,
1727 ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option
1728 LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default).
1729 Be careful, disabling ICMP make your product non-compliant to RFC1122, but
1730 help to reduce footprint, and to reduce "visibility" on the Internet.
1731
1732 2007-09-05 Frédéric Bernon, Bill Florac
1733 * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list
1734 for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new
1735 parameters have to be provided: a task name, and a task stack size. For this
1736 one, since it's platform dependant, you could define the best one for you in
1737 your lwipopts.h. For port maintainers, you can just add these new parameters
1738 in your sys_arch.c file, and but it's not mandatory, use them in your OS
1739 specific functions.
1740
1741 2007-09-05 Frédéric Bernon
1742 * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings
1743 inside init.c for task #7142 "Sanity check user-configurable values".
1744
1745 2007-09-04 Frédéric Bernon, Bill Florac
1746 * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by
1747 memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the
1748 value). It will avoid potential fragmentation problems, use a counter to know
1749 how many times a group is used on an netif, and free it when all applications
1750 leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity
1751 check if LWIP_IGMP!=0).
1752
1753 2007-09-03 Frédéric Bernon
1754 * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement".
1755 Initialize igmp_mac_filter to NULL in netif_add (this field should be set in
1756 the netif's "init" function). Use the "imr_interface" field (for socket layer)
1757 and/or the "interface" field (for netconn layer), for join/leave operations.
1758 The igmp_join/leavegroup first parameter change from a netif to an ipaddr.
1759 This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany).
1760
1761 2007-08-30 Frédéric Bernon
1762 * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions
1763 from api/api_lib". Now netbuf API is independant of netconn, and can be used
1764 with other API (application based on raw API, or future "socket2" API). Ports
1765 maintainers just have to add src/api/netbuf.c in their makefile/projects.
1766
1767 2007-08-30 Frédéric Bernon, Jonathan Larmour
1768 * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check
1769 user-configurable values".
1770
1771 2007-08-29 Frédéric Bernon
1772 * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start.
1773 igmp_start is call inside netif_add. Now, igmp initialization is in the same
1774 spirit than the others modules. Modify some IGMP debug traces.
1775
1776 2007-08-29 Frédéric Bernon
1777 * Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function"
1778 Add lwip_init function to regroup all modules initializations, and to provide
1779 a place to add code for task #7142 "Sanity check user-configurable values".
1780 Ports maintainers should remove direct initializations calls from their code,
1781 and add init.c in their makefiles. Note that lwip_init() function is called
1782 inside tcpip_init, but can also be used by raw api users since all calls are
1783 disabled when matching options are disabled. Also note that their is new options
1784 in opt.h, you should configure in your lwipopts.h (they are enabled per default).
1785
1786 2007-08-26 Marc Boucher
1787 * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL
1788 since they can under certain circumstances be called with an invalid conn
1789 pointer after the connection has been closed (and conn has been freed).
1790
1791 2007-08-25 Frédéric Bernon (Artem Migaev's Patch)
1792 * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up".
1793 Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set.
1794
1795 2007-08-22 Frédéric Bernon
1796 * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK
1797 to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release.
1798
1799 2007-08-22 Frédéric Bernon
1800 * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT &
1801 ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the
1802 name is tcpip_input (we keep the name of 1.2.0 function).
1803
1804 2007-08-17 Jared Grubb
1805 * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool
1806 settings into new memp_std.h and optional user file lwippools.h. This adds
1807 more dynamic mempools, and allows the user to create an arbitrary number of
1808 mempools for mem_malloc.
1809
1810 2007-08-16 Marc Boucher
1811 * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function;
1812 otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely
1813 close the connection.
1814
1815 2007-08-16 Marc Boucher
1816 * sockets.c: lwip_accept(): check netconn_peer() error return.
1817
1818 2007-08-16 Marc Boucher
1819 * mem.c, mem.h: Added mem_calloc().
1820
1821 2007-08-16 Marc Boucher
1822 * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT)
1823 for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG
1824 and starving other message types.
1825 Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API
1826
1827 2007-08-16 Marc Boucher
1828 * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf
1829 type and flgs (later renamed to flags).
1830 Use enum pbuf_flag as pbuf_type. Renumber PBUF_FLAG_*.
1831 Improved lwip_recvfrom(). TCP push now propagated.
1832
1833 2007-08-16 Marc Boucher
1834 * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global
1835 provided by etharp.
1836
1837 2007-08-16 Marc Boucher
1838 * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h,
1839 etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c:
1840 Added PPPoE support and various PPP improvements.
1841
1842 2007-07-25 Simon Goldschmidt
1843 * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial,
1844 making netbuf_copy_partial use this function.
1845
1846 2007-07-25 Simon Goldschmidt
1847 * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with
1848 2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and
1849 other stacks.
1850
1851 2007-07-13 Jared Grubb (integrated by Frédéric Bernon)
1852 * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add
1853 a link callback in the netif struct, and functions to handle it. Be carefull
1854 for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c)
1855 if you want to be sure to be compatible with future changes...
1856
1857 2007-06-30 Frédéric Bernon
1858 * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.
1859
1860 2007-06-21 Simon Goldschmidt
1861 * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both
1862 LWIP_AUTOIP =0 and =1 to remove redundant code.
1863
1864 2007-06-21 Simon Goldschmidt
1865 * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option
1866 MEM_USE_POOLS to use 4 pools with different sized elements instead of a
1867 heap. This both prevents memory fragmentation and gives a higher speed
1868 at the cost of more memory consumption. Turned off by default.
1869
1870 2007-06-21 Simon Goldschmidt
1871 * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of
1872 netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into
1873 int to be able to send a bigger buffer than 64K with one time (mainly
1874 used from lwip_send).
1875
1876 2007-06-21 Simon Goldschmidt
1877 * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write
1878 into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too.
1879
1880 2007-06-21 Simon Goldschmidt
1881 * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in
1882 netconn_write from api_lib.c to api_msg.c to also prevent multiple context-
1883 changes on low memory or empty send-buffer.
1884
1885 2007-06-18 Simon Goldschmidt
1886 * etharp.c, etharp.h: Changed etharp to use a defined hardware address length
1887 of 6 to avoid loading netif->hwaddr_len every time (since this file is only
1888 used for ethernet and struct eth_addr already had a defined length of 6).
1889
1890 2007-06-17 Simon Goldschmidt
1891 * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets
1892 to disable UDP checksum generation on transmit.
1893
1894 2007-06-13 Frédéric Bernon, Simon Goldschmidt
1895 * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid
1896 pointers or parameters, and let the possibility to redefined it in cc.h. Use
1897 this macro to check "conn" parameter in api_msg.c functions.
1898
1899 2007-06-11 Simon Goldschmidt
1900 * sockets.c, sockets.h: Added UDP lite support for sockets
1901
1902 2007-06-10 Simon Goldschmidt
1903 * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled
1904 by default) to switch off UDP-Lite support if not needed (reduces udp.c code
1905 size)
1906
1907 2007-06-09 Dominik Spies (integrated by Frédéric Bernon)
1908 * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h:
1909 AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and
1910 LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt
1911 (see TODO mark in the source code).
1912
1913 2007-06-09 Simon Goldschmidt
1914 * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for
1915 etharp_output() to match netif->output so etharp_output() can be used
1916 directly as netif->output to save one function call.
1917
1918 2007-06-08 Simon Goldschmidt
1919 * netif.h, ethernetif.c, slipif.c, loopif.c: Added define
1920 NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables,
1921 added initialization of those to ethernetif, slipif and loopif.
1922
1923 2007-05-18 Simon Goldschmidt
1924 * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF
1925 (defaulting to off for now) that can be set to 0 to send fragmented
1926 packets by passing PBUF_REFs down the stack.
1927
1928 2007-05-23 Frédéric Bernon
1929 * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP
1930 connections, such present in patch #5959.
1931
1932 2007-05-23 Frédéric Bernon
1933 * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx
1934 code in only one part...
1935
1936 2007-05-18 Simon Goldschmidt
1937 * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp
1938 elements to overflow. This is achieved by adding some bytes before and after
1939 each pool element (increasing their size, of course), filling them with a
1940 prominent value and checking them on freeing the element.
1941 Set it to 2 to also check every element in every pool each time memp_malloc()
1942 or memp_free() is called (slower but more helpful).
1943
1944 2007-05-10 Simon Goldschmidt
1945 * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for
1946 PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce
1947 code size.
1948
1949 2007-05-11 Frédéric Bernon
1950 * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c:
1951 Include a function pointer instead of a table index in the message to reduce
1952 footprint. Disable some part of lwip_send and lwip_sendto if some options are
1953 not set (LWIP_TCP, LWIP_UDP, LWIP_RAW).
1954
1955 2007-05-10 Simon Goldschmidt
1956 * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus
1957 \ extern "C" {' in all header files. Now you can write your application using
1958 the lwIP stack in C++ and simply #include the core files. Note I have left
1959 out the netif/ppp/*h header files for now, since I don't know which files are
1960 included by applications and which are for internal use only.
1961
1962 2007-05-09 Simon Goldschmidt
1963 * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library
1964 memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for
1965 situations where some compilers might inline the copy and save a function
1966 call. Also replaced all calls to memcpy() with calls to (S)MEMCPY().
1967
1968 2007-05-08 Simon Goldschmidt
1969 * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc())
1970 to be overriden in case the C-library malloc implementation is not protected
1971 against concurrent access.
1972
1973 2007-05-04 Simon Goldschmidt (Atte Kojo)
1974 * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending
1975 multiple packets to the same host.
1976
1977 2007-05-04 Frédéric Bernon, Jonathan Larmour
1978 * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible
1979 to corrupt remote addr/port connection state". Reduce problems "not enought memory" with
1980 netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between
1981 sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function.
1982 Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct,
1983 these fields are now renamed "addr" & "port".
1984
1985 2007-04-11 Jonathan Larmour
1986 * sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new
1987 sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return
1988 with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro
1989 by the port in sys_arch.h if desired.
1990
1991 2007-04-06 Frédéric Bernon, Simon Goldschmidt
1992 * opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API
1993 allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp
1994 clients, using new functions from netifapi.h. Disable as default (no port change to do).
1995
1996 2007-04-05 Frédéric Bernon
1997 * sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant.
1998
1999 2007-04-04 Simon Goldschmidt
2000 * arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x)
2001 use this for and architecture-independent form to tell the compiler you intentionally
2002 are not using this variable. Can be overriden in cc.h.
2003
2004 2007-03-28 Frédéric Bernon
2005 * opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to
2006 define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded
2007 string, point on one of your's ethernetif field, or alloc a string you will free yourself).
2008 It will be used by DHCP to register a client hostname, but can also be use when you call
2009 snmp_set_sysname.
2010
2011 2007-03-28 Frédéric Bernon
2012 * netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to
2013 initialize a network interface's flag with. It tell this interface is an ethernet
2014 device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility
2015 Support for IPv4" section 4.6) when interface is "up" with netif_set_up().
2016
2017 2007-03-26 Frédéric Bernon, Jonathan Larmour
2018 * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build
2019 time if you only use PPP or SLIP. The default is enable. Note we don't have to call
2020 etharp_init in your port's initilization sequence if you use tcpip.c, because this call
2021 is done in tcpip_init function.
2022
2023 2007-03-22 Frédéric Bernon
2024 * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the
2025 new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in
2026 your lwipopts.h. More, unused counters are not defined in the stats structs, and not
2027 display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined
2028 but never used. Fix msg_in.c with the correct #if test for a stat display.
2029
2030 2007-03-21 Kieran Mansley
2031 * netif.c, netif.h: Apply patch#4197 with some changes (originator: rireland@hmgsl.com).
2032 Provides callback on netif up/down state change.
2033
2034 2007-03-11 Frédéric Bernon, Mace Gael, Steve Reynolds
2035 * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, igmp.h, igmp.c,
2036 ip.c, netif.h, tcpip.c, opt.h:
2037 New configuration option LWIP_IGMP to enable IGMP processing. Based on only one
2038 filter per all network interfaces. Declare a new function in netif to enable to
2039 control the MAC filter (to reduce lwIP traffic processing).
2040
2041 2007-03-11 Frédéric Bernon
2042 * tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can
2043 be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this
2044 unless you know what you're doing (default are RFC1122 compliant). Note
2045 that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds.
2046
2047 2007-03-08 Frédéric Bernon
2048 * tcp.h: Keepalive values can be configured at compile time, but don't change
2049 this unless you know what you're doing (default are RFC1122 compliant).
2050
2051 2007-03-08 Frédéric Bernon
2052 * sockets.c, api.h, api_lib.c, tcpip.c, sys.h, sys.c, err.c, opt.h:
2053 Implement LWIP_SO_RCVTIMEO configuration option to enable/disable SO_RCVTIMEO
2054 on UDP sockets/netconn.
2055
2056 2007-03-08 Simon Goldschmidt
2057 * snmp_msg.h, msg_in.c: SNMP UDP ports can be configured at compile time.
2058
2059 2007-03-06 Frédéric Bernon
2060 * api.h, api_lib.c, sockets.h, sockets.c, tcpip.c, sys.h, sys.c, err.h:
2061 Implement SO_RCVTIMEO on UDP sockets/netconn.
2062
2063 2007-02-28 Kieran Mansley (based on patch from Simon Goldschmidt)
2064 * api_lib.c, tcpip.c, memp.c, memp.h: make API msg structs allocated
2065 on the stack and remove the API msg type from memp
2066
2067 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
2068 * sockets.h, sockets.c: Move socket initialization to new
2069 lwip_socket_init() function.
2070 NOTE: this changes the API with ports. Ports will have to be
2071 updated to call lwip_socket_init() now.
2072
2073 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
2074 * api_lib.c: Use memcpy in netbuf_copy_partial.
2075
2076
2077 ++ Bug fixes:
2078
2079 2008-03-17 Frédéric Bernon, Ed Kerekes
2080 * igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have
2081 some problems to fill the IP header on some targets, use now the
2082 ip.h macros to do it).
2083
2084 2008-03-13 Frédéric Bernon
2085 * sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using
2086 (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a
2087 TCP connection caused a crash. Note that using (lwip_)recvfrom
2088 like this is a bit slow and that using (lwip)getpeername is the
2089 good lwip way to do it (so, using recv is faster on tcp sockets).
2090
2091 2008-03-12 Frédéric Bernon, Jonathan Larmour
2092 * api_msg.c, contrib/apps/ping.c: Fix bug #22530 "api_msg.c's
2093 recv_raw() does not consume data", and the ping sample (with
2094 LWIP_SOCKET=1, the code did the wrong supposition that lwip_recvfrom
2095 returned the IP payload, without the IP header).
2096
2097 2008-03-04 Jonathan Larmour
2098 * mem.c, stats.c, mem.h: apply patch #6414 to avoid compiler errors
2099 and/or warnings on some systems where mem_size_t and size_t differ.
2100 * pbuf.c, ppp.c: Fix warnings on some systems with mem_malloc.
2101
2102 2008-03-04 Kieran Mansley (contributions by others)
2103 * Numerous small compiler error/warning fixes from contributions to
2104 mailing list after 1.3.0 release candidate made.
2105
2106 2008-01-25 Cui hengbin (integrated by Frédéric Bernon)
2107 * dns.c: Fix bug #22108 "DNS problem" caused by unaligned structures.
2108
2109 2008-01-15 Kieran Mansley
2110 * tcp_out.c: BUG20511. Modify persist timer to start when we are
2111 prevented from sending by a small send window, not just a zero
2112 send window.
2113
2114 2008-01-09 Jonathan Larmour
2115 * opt.h, ip.c: Rename IP_OPTIONS define to IP_OPTIONS_ALLOWED to avoid
2116 conflict with Linux system headers.
2117
2118 2008-01-06 Jonathan Larmour
2119 * dhcp.c: fix bug #19927: "DHCP NACK problem" by clearing any existing set IP
2120 address entirely on receiving a DHCPNAK, and restarting discovery.
2121
2122 2007-12-21 Simon Goldschmidt
2123 * sys.h, api_lib.c, api_msg.c, sockets.c: fix bug #21698: "netconn->recv_avail
2124 is not protected" by using new macros for interlocked access to modify/test
2125 netconn->recv_avail.
2126
2127 2007-12-20 Kieran Mansley (based on patch from Oleg Tyshev)
2128 * tcp_in.c: fix bug# 21535 (nrtx not reset correctly in SYN_SENT state)
2129
2130 2007-12-20 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
2131 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: fix bug #20199 (better handling
2132 of silly window avoidance and prevent lwIP from shrinking the window)
2133
2134 2007-12-04 Simon Goldschmidt
2135 * tcp.c, tcp_in.c: fix bug #21699 (segment leak in ooseq processing when last
2136 data packet was lost): add assert that all segment lists are empty in
2137 tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED
2138 state from LAST_ACK in tcp_process
2139
2140 2007-12-02 Simon Goldschmidt
2141 * sockets.h: fix bug #21654: exclude definition of struct timeval from #ifndef FD_SET
2142 If including <sys/time.h> for system-struct timeval, LWIP_TIMEVAL_PRIVATE now
2143 has to be set to 0 in lwipopts.h
2144
2145 2007-12-02 Simon Goldschmidt
2146 * api_msg.c, api_lib.c: fix bug #21656 (recvmbox problem in netconn API): always
2147 allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen
2148 netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox.
2149 This is a fix for thread-safety and allocates all items needed for a netconn
2150 when the netconn is created.
2151
2152 2007-11-30 Simon Goldschmidt
2153 * udp.c: first attempt to fix bug #21655 (DHCP doesn't work reliably with multiple
2154 netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed
2155 to netif->dhcp->pcb only (if that exists) and not to any other pcb for the same
2156 port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address)
2157
2158 2007-11-27 Simon Goldschmidt
2159 * ip.c: fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by
2160 letting ip_route only use netifs that are up.
2161
2162 2007-11-27 Simon Goldschmidt
2163 * err.h, api_lib.c, api_msg.c, sockets.c: Changed error handling: ERR_MEM, ERR_BUF
2164 and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and
2165 sockets block most operations once they have seen a fatal error.
2166
2167 2007-11-27 Simon Goldschmidt
2168 * udp.h, udp.c, dhcp.c: Implemented new function udp_sendto_if which takes the
2169 netif to send as an argument (to be able to send on netifs that are down).
2170
2171 2007-11-26 Simon Goldschmidt
2172 * tcp_in.c: Fixed bug #21582: pcb->acked accounting can be wrong when ACKs
2173 arrive out-of-order
2174
2175 2007-11-21 Simon Goldschmidt
2176 * tcp.h, tcp_out.c, api_msg.c: Fixed bug #20287: tcp_output_nagle sends too early
2177 Fixed the nagle algorithm; nagle now also works for all raw API applications
2178 and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY'
2179
2180 2007-11-12 Frédéric Bernon
2181 * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most
2182 of the netconn_peer and netconn_addr processing is done inside tcpip_thread
2183 context in do_getaddr.
2184
2185 2007-11-10 Simon Goldschmidt
2186 * etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can
2187 happen any time). Now the packet simply isn't enqueued when out of memory.
2188
2189 2007-11-01 Simon Goldschmidt
2190 * tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or
2191 TCP_MSS if that is smaller) as long as no MSS option is received from the
2192 remote host.
2193
2194 2007-11-01 Simon Goldschmidt
2195 * tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN)
2196 is now based on TCP_MSS instead of pcb->mss (on passive open now effectively
2197 sending our configured TCP_MSS instead of the one received).
2198
2199 2007-11-01 Simon Goldschmidt
2200 * tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was
2201 calculated based on the configured TCP_MSS, not on the MSS option received
2202 with SYN+ACK.
2203
2204 2007-10-09 Simon Goldschmidt
2205 * udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too
2206 short and also was generated wrong if checksum coverage != tot_len;
2207 receive: checksum was calculated wrong if checksum coverage != tot_len
2208
2209 2007-10-08 Simon Goldschmidt
2210 * mem.c: lfree was not updated in mem_realloc!
2211
2212 2007-10-07 Frédéric Bernon
2213 * sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential
2214 crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT:
2215 this change cause an API breakage for netconn_addr, since a parameter
2216 type change. Any compiler should cause an error without any changes in
2217 yours netconn_peer calls (so, it can't be a "silent change"). It also
2218 reduce a little bit the footprint for socket layer (lwip_getpeername &
2219 lwip_getsockname use now a common lwip_getaddrname function since
2220 netconn_peer & netconn_addr have the same parameters).
2221
2222 2007-09-20 Simon Goldschmidt
2223 * tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state)
2224 by checking tcp_tw_pcbs also
2225
2226 2007-09-19 Simon Goldschmidt
2227 * icmp.c: Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies)
2228
2229 2007-09-15 Mike Kleshov
2230 * mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used)
2231
2232 2007-09-06 Frédéric Bernon
2233 * several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove
2234 it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which
2235 already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h"
2236 if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h.
2237
2238 2007-08-30 Frédéric Bernon
2239 * igmp.h, igmp.c: Some changes to remove some redundant code, add some traces,
2240 and fix some coding style.
2241
2242 2007-08-28 Frédéric Bernon
2243 * tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any
2244 kind of packets. These packets are considered like Ethernet packets (payload
2245 pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets
2246 are considered like IP packets (payload pointing to iphdr).
2247
2248 2007-08-27 Frédéric Bernon
2249 * api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error
2250 problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state
2251 and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT).
2252
2253 2007-08-24 Kieran Mansley
2254 * inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy
2255 compiler (Paradigm C++)
2256
2257 2007-08-09 Frédéric Bernon, Bill Florac
2258 * stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement.
2259 Introduce IGMP_STATS to centralize statistics management.
2260
2261 2007-08-09 Frédéric Bernon, Bill Florac
2262 * udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast
2263 packet on a udp pcb binded on an netif's IP address, and not on "any".
2264
2265 2007-08-09 Frédéric Bernon, Bill Florac
2266 * igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement.
2267 This is mainly on using lookup/lookfor, and some coding styles...
2268
2269 2007-07-26 Frédéric Bernon (and "thedoctor")
2270 * igmp.c: Fix bug #20595 to accept IGMPv3 "Query" messages.
2271
2272 2007-07-25 Simon Goldschmidt
2273 * api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if
2274 tcp_output fails in tcp_close, the code in do_close_internal gets simpler
2275 (tcp_output is called again later from tcp timers).
2276
2277 2007-07-25 Simon Goldschmidt
2278 * ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old
2279 copy_from_pbuf, which illegally modified the given pbuf.
2280
2281 2007-07-25 Simon Goldschmidt
2282 * tcp_out.c: tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs:
2283 changed snd_queuelen++ to snd_queuelen += pbuf_clen(p).
2284
2285 2007-07-24 Simon Goldschmidt
2286 * api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the
2287 correct state (must be CLOSED).
2288
2289 2007-07-13 Thomas Taranowski (commited by Jared Grubb)
2290 * memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed
2291 allocation. It now returns NULL.
2292
2293 2007-07-13 Frédéric Bernon
2294 * api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in
2295 all error cases.
2296
2297 2007-07-13 Frédéric Bernon
2298 * api_msg.c: Fix bug #20315: possible memory leak problem if tcp_listen failed,
2299 because current code doesn't follow rawapi.txt documentation.
2300
2301 2007-07-13 Kieran Mansley
2302 * src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in
2303 out of sequence processing of received packets
2304
2305 2007-07-03 Simon Goldschmidt
2306 * nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an
2307 assumption is made that this pbuf is in one piece (i.e. not chained). These
2308 assumptions clash with the possibility of converting to fully pool-based
2309 pbuf implementations, where PBUF_RAM pbufs might be chained.
2310
2311 2007-07-03 Simon Goldschmidt
2312 * api.h, api_lib.c, api_msg.c: Final fix for bug #20021 and some other problems
2313 when closing tcp netconns: removed conn->sem, less context switches when
2314 closing, both netconn_close and netconn_delete should safely close tcp
2315 connections.
2316
2317 2007-07-02 Simon Goldschmidt
2318 * ipv4/ip.h, ipv6/ip.h, opt.h, netif.h, etharp.h, ipv4/ip.c, netif.c, raw.c,
2319 tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off)
2320 to cache ARP table indices with each pcb instead of single-entry cache for
2321 the complete stack.
2322
2323 2007-07-02 Simon Goldschmidt
2324 * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent
2325 warnings when assigning to smaller types.
2326
2327 2007-06-28 Simon Goldschmidt
2328 * tcp_out.c: Added check to prevent tcp_pcb->snd_queuelen from overflowing.
2329
2330 2007-06-28 Simon Goldschmidt
2331 * tcp.h: Fixed bug #20287: Fixed nagle algorithm (sending was done too early if
2332 a segment contained chained pbufs)
2333
2334 2007-06-28 Frédéric Bernon
2335 * autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute
2336 a "pseudo-random" value based on netif's MAC and some autoip fields. It's always
2337 possible to define this macro in your own lwipopts.h to always use C library's
2338 rand(). Note that autoip_create_rand_addr doesn't use this macro.
2339
2340 2007-06-28 Frédéric Bernon
2341 * netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option
2342 LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications
2343 in api_lib/api_msg (use pointers and not type with table, etc...)
2344
2345 2007-06-26 Simon Goldschmidt
2346 * udp.h: Fixed bug #20259: struct udp_hdr was lacking the packin defines.
2347
2348 2007-06-25 Simon Goldschmidt
2349 * udp.c: Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload
2350 for udp packets with no matching pcb.
2351
2352 2007-06-25 Simon Goldschmidt
2353 * udp.c: Fixed bug #20220: UDP PCB search in udp_input(): a non-local match
2354 could get udp input packets if the remote side matched.
2355
2356 2007-06-13 Simon Goldschmidt
2357 * netif.c: Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get
2358 changed in netif_set_ipaddr if previous netif->ip_addr.addr was 0.
2359
2360 2007-06-13 Simon Goldschmidt
2361 * api_msg.c: pcb_new sets conn->err if protocol is not implemented
2362 -> netconn_new_..() does not allocate a new connection for unsupported
2363 protocols.
2364
2365 2007-06-13 Frédéric Bernon, Simon Goldschmidt
2366 * api_lib.c: change return expression in netconn_addr and netconn_peer, because
2367 conn->err was reset to ERR_OK without any reasons (and error was lost)...
2368
2369 2007-06-13 Frédéric Bernon, Matthias Weisser
2370 * opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename
2371 MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid
2372 some macro names collision with some OS macros.
2373
2374 2007-06-11 Simon Goldschmidt
2375 * udp.c: UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0,
2376 create checksum over the complete packet. On RX, if it's < 8 (and not 0),
2377 discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both
2378 UDP & UDP Lite.
2379
2380 2007-06-11 Srinivas Gollakota & Oleg Tyshev
2381 * tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP flags"
2382 where TCP flags wasn't initialized in tcp_keepalive.
2383
2384 2007-06-03 Simon Goldschmidt
2385 * udp.c: udp_input(): Input pbuf was not freed if pcb had no recv function
2386 registered, p->payload was modified without modifying p->len if sending
2387 icmp_dest_unreach() (had no negative effect but was definitively wrong).
2388
2389 2007-06-03 Simon Goldschmidt
2390 * icmp.c: Corrected bug #19937: For responding to an icmp echo request, icmp
2391 re-used the input pbuf even if that didn't have enough space to include the
2392 link headers. Now the space is tested and a new pbuf is allocated for the
2393 echo response packet if the echo request pbuf isn't big enough.
2394
2395 2007-06-01 Simon Goldschmidt
2396 * sockets.c: Checked in patch #5914: Moved sockopt processing into tcpip_thread.
2397
2398 2007-05-23 Frédéric Bernon
2399 * api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only
2400 allocated by do_listen if success) and netconn_accept errors handling. In
2401 most of api_lib functions, we replace some errors checkings like "if (conn==NULL)"
2402 by ASSERT, except for netconn_delete.
2403
2404 2007-05-23 Frédéric Bernon
2405 * api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return
2406 an error code if it's impossible to fetch a pbuf on a TCP connection (and not
2407 directly close the recvmbox).
2408
2409 2007-05-22 Simon Goldschmidt
2410 * tcp.c: Fixed bug #1895 (tcp_bind not correct) by introducing a list of
2411 bound but unconnected (and non-listening) tcp_pcbs.
2412
2413 2007-05-22 Frédéric Bernon
2414 * sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only
2415 used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of
2416 sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features
2417 like "sys_timeout" in their application threads.
2418
2419 2007-05-22 Frédéric Bernon
2420 * api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see
2421 which parameters are used by which do_xxx function, and to avoid "misusing"
2422 parameters (patch #5938).
2423
2424 2007-05-22 Simon Goldschmidt
2425 * api_lib.c, api_msg.c, raw.c, api.h, api_msg.h, raw.h: Included patch #5938:
2426 changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto
2427 is only 8 bits wide. This affects the api, as there, the protocol was
2428 u16_t, too.
2429
2430 2007-05-18 Simon Goldschmidt
2431 * memp.c: addition to patch #5913: smaller pointer was returned but
2432 memp_memory was the same size -> did not save memory.
2433
2434 2007-05-16 Simon Goldschmidt
2435 * loopif.c, slipif.c: Fix bug #19729: free pbuf if netif->input() returns
2436 != ERR_OK.
2437
2438 2007-05-16 Simon Goldschmidt
2439 * api_msg.c, udp.c: If a udp_pcb has a local_ip set, check if it is the same
2440 as the one of the netif used for sending to prevent sending from old
2441 addresses after a netif address gets changed (partly fixes bug #3168).
2442
2443 2007-05-16 Frédéric Bernon
2444 * tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work
2445 with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in
2446 tcpip_init) because we have to be sure that network interfaces are already
2447 added (mac filter is updated only in igmp_init for the moment).
2448
2449 2007-05-16 Simon Goldschmidt
2450 * mem.c, memp.c: Removed semaphores from memp, changed sys_sem_wait calls
2451 into sys_arch_sem_wait calls to prevent timers from running while waiting
2452 for the heap. This fixes bug #19167.
2453
2454 2007-05-13 Simon Goldschmidt
2455 * tcp.h, sockets.h, sockets.c: Fixed bug from patch #5865 by moving the defines
2456 for socket options (lwip_set/-getsockopt) used with level IPPROTO_TCP from
2457 tcp.h to sockets.h.
2458
2459 2007-05-07 Simon Goldschmidt
2460 * mem.c: Another attempt to fix bug #17922.
2461
2462 2007-05-04 Simon Goldschmidt
2463 * pbuf.c, pbuf.h, etharp.c: Further update to ARP queueing: Changed pbuf_copy()
2464 implementation so that it can be reused (don't allocate the target
2465 pbuf inside pbuf_copy()).
2466
2467 2007-05-04 Simon Goldschmidt
2468 * memp.c: checked in patch #5913: in memp_malloc() we can return memp as mem
2469 to save a little RAM (next pointer of memp is not used while not in pool).
2470
2471 2007-05-03 "maq"
2472 * sockets.c: Fix ioctl FIONREAD when some data remains from last recv.
2473 (patch #3574).
2474
2475 2007-04-23 Simon Goldschmidt
2476 * loopif.c, loopif.h, opt.h, src/netif/FILES: fix bug #2595: "loopif results
2477 in NULL reference for incoming TCP packets". Loopif has to be configured
2478 (using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input()
2479 (multithreading environments, e.g. netif->input() = tcpip_input()) or
2480 putting packets on a list that is fed to the stack by calling loopif_poll()
2481 (single-thread / NO_SYS / polling environment where e.g.
2482 netif->input() = ip_input).
2483
2484 2007-04-17 Jonathan Larmour
2485 * pbuf.c: Use s32_t in pbuf_realloc(), as an s16_t can't reliably hold
2486 the difference between two u16_t's.
2487 * sockets.h: FD_SETSIZE needs to match number of sockets, which is
2488 MEMP_NUM_NETCONN in sockets.c right now.
2489
2490 2007-04-12 Jonathan Larmour
2491 * icmp.c: Reset IP header TTL in ICMP ECHO responses (bug #19580).
2492
2493 2007-04-12 Kieran Mansley
2494 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Modify way the retransmission
2495 timer is reset to fix bug#19434, with help from Oleg Tyshev.
2496
2497 2007-04-11 Simon Goldschmidt
2498 * etharp.c, pbuf.c, pbuf.h: 3rd fix for bug #11400 (arp-queuing): More pbufs than
2499 previously thought need to be copied (everything but PBUF_ROM!). Cleaned up
2500 pbuf.c: removed functions no needed any more (by etharp).
2501
2502 2007-04-11 Kieran Mansley
2503 * inet.c, ip_addr.h, sockets.h, sys.h, tcp.h: Apply patch #5745: Fix
2504 "Constant is long" warnings with 16bit compilers. Contributed by
2505 avatar@mmlab.cse.yzu.edu.tw
2506
2507 2007-04-05 Frédéric Bernon, Jonathan Larmour
2508 * api_msg.c: Fix bug #16830: "err_tcp() posts to connection mailbox when no pend on
2509 the mailbox is active". Now, the post is only done during a connect, and do_send,
2510 do_write and do_join_leave_group don't do anything if a previous error was signaled.
2511
2512 2007-04-03 Frédéric Bernon
2513 * ip.c: Don't set the IP_DF ("Don't fragment") flag in the IP header in IP output
2514 packets. See patch #5834.
2515
2516 2007-03-30 Frédéric Bernon
2517 * api_msg.c: add a "pcb_new" helper function to avoid redundant code, and to add
2518 missing pcb allocations checking (in do_bind, and for each raw_new). Fix style.
2519
2520 2007-03-30 Frédéric Bernon
2521 * most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with
2522 others environment defines (these were too "generic").
2523
2524 2007-03-28 Frédéric Bernon
2525 * api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal pbuf_alloc call
2526 result and can cause a crash. lwip_send now check netbuf_ref result.
2527
2528 2007-03-28 Simon Goldschmidt
2529 * sockets.c Remove "#include <errno.h>" from sockets.c to avoid multiple
2530 definition of macros (in errno.h and lwip/arch.h) if LWIP_PROVIDE_ERRNO is
2531 defined. This is the way it should have been already (looking at
2532 doc/sys_arch.txt)
2533
2534 2007-03-28 Kieran Mansley
2535 * opt.h Change default PBUF_POOL_BUFSIZE (again) to accomodate default MSS +
2536 IP and TCP headers *and* physical link headers
2537
2538 2007-03-26 Frédéric Bernon (based on patch from Dmitry Potapov)
2539 * api_lib.c: patch for netconn_write(), fixes a possible race condition which cause
2540 to send some garbage. It is not a definitive solution, but the patch does solve
2541 the problem for most cases.
2542
2543 2007-03-22 Frédéric Bernon
2544 * api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used).
2545
2546 2007-03-22 Frédéric Bernon
2547 * api_lib.c: somes resources couldn't be freed if there was errors during
2548 netconn_new_with_proto_and_callback.
2549
2550 2007-03-22 Frédéric Bernon
2551 * ethernetif.c: update netif->input calls to check return value. In older ports,
2552 it's a good idea to upgrade them, even if before, there could be another problem
2553 (access to an uninitialized mailbox).
2554
2555 2007-03-21 Simon Goldschmidt
2556 * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed
2557 by casting to unsigned).
2558
2559 2007-03-21 Frédéric Bernon
2560 * api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from
2561 api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a
2562 dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call.
2563 Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a
2564 faster and more reliable communication between api_lib and tcpip.
2565
2566 2007-03-21 Frédéric Bernon
2567 * opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0.
2568
2569 2007-03-21 Frédéric Bernon
2570 * api_msg.c, igmp.c, igmp.h: Fix C++ style comments
2571
2572 2007-03-21 Kieran Mansley
2573 * opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS +
2574 IP and TCP headers
2575
2576 2007-03-21 Kieran Mansley
2577 * Fix all uses of pbuf_header to check the return value. In some
2578 cases just assert if it fails as I'm not sure how to fix them, but
2579 this is no worse than before when they would carry on regardless
2580 of the failure.
2581
2582 2007-03-21 Kieran Mansley
2583 * sockets.c, igmp.c, igmp.h, memp.h: Fix C++ style comments and
2584 comment out missing header include in icmp.c
2585
2586 2007-03-20 Frédéric Bernon
2587 * memp.h, stats.c: Fix stats_display function where memp_names table wasn't
2588 synchronized with memp.h.
2589
2590 2007-03-20 Frédéric Bernon
2591 * tcpip.c: Initialize tcpip's mbox, and verify if initialized in tcpip_input,
2592 tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init problem with
2593 network interfaces. Also fix a compiler warning.
2594
2595 2007-03-20 Kieran Mansley
2596 * udp.c: Only try and use pbuf_header() to make space for headers if
2597 not a ROM or REF pbuf.
2598
2599 2007-03-19 Frédéric Bernon
2600 * api_msg.h, api_msg.c, tcpip.h, tcpip.c: Add return types to tcpip_apimsg()
2601 and api_msg_post().
2602
2603 2007-03-19 Frédéric Bernon
2604 * Remove unimplemented "memp_realloc" function from memp.h.
2605
2606 2007-03-11 Simon Goldschmidt
2607 * pbuf.c: checked in patch #5796: pbuf_alloc: len field claculation caused
2608 memory corruption.
2609
2610 2007-03-11 Simon Goldschmidt (based on patch from Dmitry Potapov)
2611 * api_lib.c, sockets.c, api.h, api_msg.h, sockets.h: Fixed bug #19251
2612 (missing `const' qualifier in socket functions), to get more compatible to
2613 standard POSIX sockets.
2614
2615 2007-03-11 Frédéric Bernon (based on patch from Dmitry Potapov)
2616 * sockets.c: Add asserts inside bind, connect and sendto to check input
2617 parameters. Remove excessive set_errno() calls after get_socket(), because
2618 errno is set inside of get_socket(). Move last sock_set_errno() inside
2619 lwip_close.
2620
2621 2007-03-09 Simon Goldschmidt
2622 * memp.c: Fixed bug #11400: New etharp queueing introduced bug: memp_memory
2623 was allocated too small.
2624
2625 2007-03-06 Simon Goldschmidt
2626 * tcpip.c: Initialize dhcp timers in tcpip_thread (if LWIP_DHCP) to protect
2627 the stack from concurrent access.
2628
2629 2007-03-06 Frédéric Bernon, Dmitry Potapov
2630 * tcpip.c, ip_frag.c, ethernetif.c: Fix some build problems, and a redundancy
2631 call to "lwip_stats.link.recv++;" in low_level_input() & ethernetif_input().
2632
2633 2007-03-06 Simon Goldschmidt
2634 * ip_frag.c, ip_frag.h: Reduce code size: don't include code in those files
2635 if IP_FRAG == 0 and IP_REASSEMBLY == 0
2636
2637 2007-03-06 Frédéric Bernon, Simon Goldschmidt
2638 * opt.h, ip_frag.h, tcpip.h, tcpip.c, ethernetif.c: add new configuration
2639 option named ETHARP_TCPIP_ETHINPUT, which enable the new tcpip_ethinput.
2640 Allow to do ARP processing for incoming packets inside tcpip_thread
2641 (protecting ARP layer against concurrent access). You can also disable
2642 old code using tcp_input with new define ETHARP_TCPIP_INPUT set to 0.
2643 Older ports have to use tcpip_ethinput.
2644
2645 2007-03-06 Simon Goldschmidt (based on patch from Dmitry Potapov)
2646 * err.h, err.c: fixed compiler warning "initialization dircards qualifiers
2647 from pointer target type"
2648
2649 2007-03-05 Frédéric Bernon
2650 * opt.h, sockets.h: add new configuration options (LWIP_POSIX_SOCKETS_IO_NAMES,
2651 ETHARP_TRUST_IP_MAC, review SO_REUSE)
2652
2653 2007-03-04 Frédéric Bernon
2654 * api_msg.c: Remove some compiler warnings : parameter "pcb" was never
2655 referenced.
2656
2657 2007-03-04 Frédéric Bernon
2658 * api_lib.c: Fix "[patch #5764] api_lib.c cleanup: after patch #5687" (from
2659 Dmitry Potapov).
2660 The api_msg struct stay on the stack (not moved to netconn struct).
2661
2662 2007-03-04 Simon Goldschmidt (based on patch from Dmitry Potapov)
2663 * pbuf.c: Fix BUG#19168 - pbuf_free can cause deadlock (if
2664 SYS_LIGHTWEIGHT_PROT=1 & freeing PBUF_RAM when mem_sem is not available)
2665 Also fixed cast warning in pbuf_alloc()
2666
2667 2007-03-04 Simon Goldschmidt
2668 * etharp.c, etharp.h, memp.c, memp.h, opt.h: Fix BUG#11400 - don't corrupt
2669 existing pbuf chain when enqueuing multiple pbufs to a pending ARP request
2670
2671 2007-03-03 Frédéric Bernon
2672 * udp.c: remove obsolete line "static struct udp_pcb *pcb_cache = NULL;"
2673 It is static, and never used in udp.c except udp_init().
2674
2675 2007-03-02 Simon Goldschmidt
2676 * tcpip.c: Moved call to ip_init(), udp_init() and tcp_init() from
2677 tcpip_thread() to tcpip_init(). This way, raw API connections can be
2678 initialized before tcpip_thread is running (e.g. before OS is started)
2679
2680 2007-03-02 Frédéric Bernon
2681 * rawapi.txt: Fix documentation mismatch with etharp.h about etharp_tmr's call
2682 interval.
2683
2684 2007-02-28 Kieran Mansley
2685 * pbuf.c: Fix BUG#17645 - ensure pbuf payload pointer is not moved
2686 outside the region of the pbuf by pbuf_header()
2687
2688 2007-02-28 Kieran Mansley
2689 * sockets.c: Fix BUG#19161 - ensure milliseconds timeout is non-zero
2690 when supplied timeout is also non-zero
2691
2692(STABLE-1.2.0)
2693
2694 2006-12-05 Leon Woestenberg
2695 * CHANGELOG: Mention STABLE-1.2.0 release.
2696
2697 ++ New features:
2698
2699 2006-12-01 Christiaan Simons
2700 * mem.h, opt.h: Added MEM_LIBC_MALLOC option.
2701 Note this is a workaround. Currently I have no other options left.
2702
2703 2006-10-26 Christiaan Simons (accepted patch by Jonathan Larmour)
2704 * ipv4/ip_frag.c: rename MAX_MTU to IP_FRAG_MAX_MTU and move define
2705 to include/lwip/opt.h.

2747 Partially accepted patch #5449 for ANSI C compatibility / build fixes.
2748 * ipv4/lwip/ip.h ipv6/lwip/ip.h: Corrected UDP-Lite protocol
2749 identifier from 170 to 136 (bug #17574).
2750
2751 2006-10-10 Christiaan Simons
2752 * api_msg.c: Fixed Nagle algorithm as reported by Bob Grice.
2753
2754 2006-08-17 Christiaan Simons
2755 * udp.c: Fixed bug #17200, added check for broadcast
2756 destinations for PCBs bound to a unicast address.
2757
2758 2006-08-07 Christiaan Simons
2759 * api_msg.c: Flushing TCP output in do_close() (bug #15926).
2760
2761 2006-06-27 Christiaan Simons
2762 * api_msg.c: Applied patch for cold case (bug #11135).
2763 In accept_function() ensure newconn->callback is always initialized.
2764
2765 2006-06-15 Christiaan Simons
2766 * mem.h: added MEM_SIZE_F alias to fix an ancient cold case (bug #1748),
2767 facilitate printing of mem_size_t and u16_t statistics.
2768
2769 2006-06-14 Christiaan Simons
2770 * api_msg.c: Applied patch #5146 to handle allocation failures
2771 in accept() by Kevin Lawson.
2772
2773 2006-05-26 Christiaan Simons
2774 * api_lib.c: Removed conn->sem creation and destruction
2775 from netconn_write() and added sys_sem_new to netconn_new_*.
2776
2777(STABLE-1_1_1)
2778
2779 2006-03-03 Christiaan Simons
2780 * ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap
2781 access and added pbuf_alloc() return value checks.
2782
2783 2006-01-01 Leon Woestenberg <leon.woestenberg@gmx.net>
2784 * tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is
2785 now handled by the checksum routine properly.
2786
2787 2006-02-27 Leon Woestenberg <leon.woestenberg@gmx.net>
2788 * pbuf.c: Fix alignment; pbuf_init() would not work unless
2789 pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.)
2790
2791 2005-12-20 Leon Woestenberg <leon.woestenberg@gmx.net>
2792 * tcp.c: Remove PCBs which stay in LAST_ACK state too long. Patch
2793 submitted by Mitrani Hiroshi.
2794
2795 2005-12-15 Christiaan Simons
2796 * inet.c: Disabled the added summing routine to preserve code space.
2797
2798 2005-12-14 Leon Woestenberg <leon.woestenberg@gmx.net>
2799 * tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
2800 Added Curt McDowell's optimized checksumming routine for future
2801 inclusion. Need to create test case for unaliged, aligned, odd,
2802 even length combination of cases on various endianess machines.
2803
2804 2005-12-09 Christiaan Simons
2805 * inet.c: Rewrote standard checksum routine in proper portable C.
2806
2807 2005-11-25 Christiaan Simons
2808 * udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
2809 * *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
2810 u32_t, s32_t typedefs. This solves most debug word-length assumes.
2811
2812 2005-07-17 Leon Woestenberg <leon.woestenberg@gmx.net>
2813 * inet.c: Fixed unaligned 16-bit access in the standard checksum
2814 routine by Peter Jolasson.
2815 * slipif.c: Fixed implementation assumption of single-pbuf datagrams.
2816
2817 2005-02-04 Leon Woestenberg <leon.woestenberg@gmx.net>
2818 * tcp_out.c: Fixed uninitialized 'queue' referenced in memerr branch.
2819 * tcp_{out|in}.c: Applied patch fixing unaligned access.
2820
2821 2005-01-04 Leon Woestenberg <leon.woestenberg@gmx.net>
2822 * pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement.
2823
2824 2005-01-03 Leon Woestenberg <leon.woestenberg@gmx.net>
2825 * udp.c: UDP pcb->recv() was called even when it was NULL.
2826
2827(STABLE-1_1_0)
2828
2829 2004-12-28 Leon Woestenberg <leon.woestenberg@gmx.net>
2830 * etharp.*: Disabled multiple packets on the ARP queue.
2831 This clashes with TCP queueing.
2832
2833 2004-11-28 Leon Woestenberg <leon.woestenberg@gmx.net>
2834 * etharp.*: Fixed race condition from ARP request to ARP timeout.
2835 Halved the ARP period, doubled the period counts.
2836 ETHARP_MAX_PENDING now should be at least 2. This prevents
2837 the counter from reaching 0 right away (which would allow
2838 too little time for ARP responses to be received).
2839
2840 2004-11-25 Leon Woestenberg <leon.woestenberg@gmx.net>
2841 * dhcp.c: Decline messages were not multicast but unicast.
2842 * etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
2843 Do not try hard to insert arbitrary packet's source address,
2844 etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
2845 etharp_query() now always DOES call ETHARP_TRY_HARD so that users
2846 querying an address will see it appear in the cache (DHCP could
2847 suffer from this when a server invalidly gave an in-use address.)
2848 * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
2849 comparing network addresses (identifiers), not the network masks
2850 themselves.
2851 * ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
2852 IP address actually belongs to the network of the given interface.
2853
2854 2004-11-24 Kieran Mansley <kjm25@cam.ac.uk>
2855 * tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.
2856
2857(STABLE-1_1_0-RC1)
2858
2859 2004-10-16 Kieran Mansley <kjm25@cam.ac.uk>
2860 * tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
2861 even if one is already pending, if the rcv_wnd is above a threshold
2862 (currently TCP_WND/2). This avoids waiting for a timer to expire to send a
2863 delayed ACK in order to open the window if the stack is only receiving data.
2864
2865 2004-09-12 Kieran Mansley <kjm25@cam.ac.uk>
2866 * tcp*.*: Retransmit time-out handling improvement by Sam Jansen.
2867
2868 2004-08-20 Tony Mountifield <tony@softins.co.uk>
2869 * etharp.c: Make sure the first pbuf queued on an ARP entry
2870 is properly ref counted.
2871
2872 2004-07-27 Tony Mountifield <tony@softins.co.uk>
2873 * debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
2874 warnings about comparison.
2875 * pbuf.c: Stopped compiler complaining of empty if statement
2876 when LWIP_DEBUGF() empty. Closed an unclosed comment.
2877 * tcp.c: Stopped compiler complaining of empty if statement
2878 when LWIP_DEBUGF() empty.
2879 * ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
2880 * inet.c: Added a couple of casts to quiet the compiler.
2881 No need to test isascii(c) before isdigit(c) or isxdigit(c).
2882
2883 2004-07-22 Tony Mountifield <tony@softins.co.uk>
2884 * inet.c: Made data types consistent in inet_ntoa().
2885 Added casts for return values of checksum routines, to pacify compiler.
2886 * ip_frag.c, tcp_out.c, sockets.c, pbuf.c
2887 Small corrections to some debugging statements, to pacify compiler.
2888
2889 2004-07-21 Tony Mountifield <tony@softins.co.uk>
2890 * etharp.c: Removed spurious semicolon and added missing end-of-comment.
2891 * ethernetif.c Updated low_level_output() to match prototype for
2892 netif->linkoutput and changed low_level_input() similarly for consistency.
2893 * api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
2894 of raw_recv() in raw.h and so avoid compiler error.
2895 * sockets.c: Added trivial (int) cast to keep compiler happier.
2896 * ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.
2897
2898(STABLE-1_0_0)
2899
2900 ++ Changes:
2901
2902 2004-07-05 Leon Woestenberg <leon.woestenberg@gmx.net>
2903 * sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure
2904 your cc.h file defines this either 1 or 0. If non-defined,
2905 defaults to 1.
2906 * .c: Added <string.h> and <errno.h> includes where used.
2907 * etharp.c: Made some array indices unsigned.
2908
2909 2004-06-27 Leon Woestenberg <leon.woestenberg@gmx.net>
2910 * netif.*: Added netif_set_up()/down().
2911 * dhcp.c: Changes to restart program flow.
2912
2913 2004-05-07 Leon Woestenberg <leon.woestenberg@gmx.net>
2914 * etharp.c: In find_entry(), instead of a list traversal per candidate, do a
2915 single-pass lookup for different candidates. Should exploit locality.
2916
2917 2004-04-29 Leon Woestenberg <leon.woestenberg@gmx.net>
2918 * tcp*.c: Cleaned up source comment documentation for Doxygen processing.
2919 * opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC.
2920 * etharp.c: update_arp_entry() only adds new ARP entries when adviced to by
2921 the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option.
2922
2923 ++ Bug fixes:
2924
2925 2004-04-27 Leon Woestenberg <leon.woestenberg@gmx.net>
2926 * etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution
2927 suggested by Timmy Brolin. Fix for 32-bit processors that cannot access
2928 non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix
2929 is to prefix the 14-bit Ethernet headers with two padding bytes.
2930
2931 2004-04-23 Leon Woestenberg <leon.woestenberg@gmx.net>
2932 * ip_addr.c: Fix in the ip_addr_isbroadcast() check.
2933 * etharp.c: Fixed the case where the packet that initiates the ARP request
2934 is not queued, and gets lost. Fixed the case where the packets destination
2935 address is already known; we now always queue the packet and perform an ARP
2936 request.
2937
2938(STABLE-0_7_0)
2939
2940 ++ Bug fixes:
2941
2942 * Fixed TCP bug for SYN_SENT to ESTABLISHED state transition.
2943 * Fixed TCP bug in dequeueing of FIN from out of order segment queue.
2944 * Fixed two possible NULL references in rare cases.
2945
2946(STABLE-0_6_6)
2947
2948 ++ Bug fixes:
2949
2950 * Fixed DHCP which did not include the IP address in DECLINE messages.
2951
2952 ++ Changes:
2953
2954 * etharp.c has been hauled over a bit.
2955
2956(STABLE-0_6_5)
2957
2958 ++ Bug fixes:
2959
2960 * Fixed TCP bug induced by bad window resizing with unidirectional TCP traffic.
2961 * Packets sent from ARP queue had invalid source hardware address.
2962
2963 ++ Changes:
2964
2965 * Pass-by ARP requests do now update the cache.
2966
2967 ++ New features:
2968
2969 * No longer dependent on ctype.h.
2970 * New socket options.
2971 * Raw IP pcb support.
2972
2973(STABLE-0_6_4)
2974
2975 ++ Bug fixes:
2976
2977 * Some debug formatters and casts fixed.
2978 * Numereous fixes in PPP.
2979
2980 ++ Changes:
2981
2982 * DEBUGF now is LWIP_DEBUGF
2983 * pbuf_dechain() has been re-enabled.
2984 * Mentioned the changed use of CVS branches in README.
2985
2986(STABLE-0_6_3)
2987
2988 ++ Bug fixes:
2989
2990 * Fixed pool pbuf memory leak in pbuf_alloc().
2991 Occured if not enough PBUF_POOL pbufs for a packet pbuf chain.
2992 Reported by Savin Zlobec.
2993
2994 * PBUF_POOL chains had their tot_len field not set for non-first
2995 pbufs. Fixed in pbuf_alloc().
2996
2997 ++ New features:
2998
2999 * Added PPP stack contributed by Marc Boucher
3000
3001 ++ Changes:
3002
3003 * Now drops short packets for ICMP/UDP/TCP protocols. More robust.
3004
3005 * ARP queueuing now queues the latest packet instead of the first.
3006 This is the RFC recommended behaviour, but can be overridden in
3007 lwipopts.h.
3008
3009(0.6.2)
3010
3011 ++ Bugfixes:
3012
3013 * TCP has been fixed to deal with the new use of the pbuf->ref
3014 counter.
3015
3016 * DHCP dhcp_inform() crash bug fixed.
3017
3018 ++ Changes:
3019
3020 * Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
3021 pbuf_refresh(). This has sped up pbuf pool operations considerably.
3022 Implemented by David Haas.
3023
3024(0.6.1)
3025
3026 ++ New features:
3027
3028 * The packet buffer implementation has been enhanced to support
3029 zero-copy and copy-on-demand for packet buffers which have their
3030 payloads in application-managed memory.
3031 Implemented by David Haas.
3032
3033 Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
3034 if an outgoing packet can be directly sent on the link, or perform
3035 a copy-on-demand when necessary.
3036
3037 The application can safely assume the packet is sent, and the RAM
3038 is available to the application directly after calling udp_send()
3039 or similar function.
3040
3041 ++ Bugfixes:
3042
3043 * ARP_QUEUEING should now correctly work for all cases, including
3044 PBUF_REF.
3045 Implemented by Leon Woestenberg.
3046
3047 ++ Changes:
3048
3049 * IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
3050 to a '0.0.0.0' IP address.
3051
3052 * The packet buffer implementation is changed. The pbuf->ref counter
3053 meaning has changed, and several pbuf functions have been
3054 adapted accordingly.
3055
3056 * netif drivers have to be changed to set the hardware address length field
3057 that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).
3058 See the contrib/ports/c16x cs8900 driver as a driver example.
3059
3060 * netif's have a dhcp field that must be initialized to NULL by the driver.
3061 See the contrib/ports/c16x cs8900 driver as a driver example.
3062
3063(0.5.x) This file has been unmaintained up to 0.6.1. All changes are
3064 logged in CVS but have not been explained here.
3065
3066(0.5.3) Changes since version 0.5.2
3067
3068 ++ Bugfixes:
3069
3070 * memp_malloc(MEMP_API_MSG) could fail with multiple application
3071 threads because it wasn't protected by semaphores.
3072
3073 ++ Other changes:
3074
3075 * struct ip_addr now packed.
3076
3077 * The name of the time variable in arp.c has been changed to ctime
3078 to avoid conflicts with the time() function.
3079
3080(0.5.2) Changes since version 0.5.1
3081
3082 ++ New features:
3083
3084 * A new TCP function, tcp_tmr(), now handles both TCP timers.
3085
3086 ++ Bugfixes:
3087
3088 * A bug in tcp_parseopt() could cause the stack to hang because of a
3089 malformed TCP option.
3090
3091 * The address of new connections in the accept() function in the BSD
3092 socket library was not handled correctly.
3093
3094 * pbuf_dechain() did not update the ->tot_len field of the tail.
3095
3096 * Aborted TCP connections were not handled correctly in all
3097 situations.
3098
3099 ++ Other changes:
3100
3101 * All protocol header structs are now packed.
3102
3103 * The ->len field in the tcp_seg structure now counts the actual
3104 amount of data, and does not add one for SYN and FIN segments.
3105
3106(0.5.1) Changes since version 0.5.0
3107
3108 ++ New features:
3109
3110 * Possible to run as a user process under Linux.
3111
3112 * Preliminary support for cross platform packed structs.
3113
3114 * ARP timer now implemented.
3115
3116 ++ Bugfixes:
3117
3118 * TCP output queue length was badly initialized when opening
3119 connections.
3120
3121 * TCP delayed ACKs were not sent correctly.
3122
3123 * Explicit initialization of BSS segment variables.
3124
3125 * read() in BSD socket library could drop data.
3126
3127 * Problems with memory alignment.
3128
3129 * Situations when all TCP buffers were used could lead to
3130 starvation.
3131
3132 * TCP MSS option wasn't parsed correctly.
3133
3134 * Problems with UDP checksum calculation.
3135
3136 * IP multicast address tests had endianess problems.
3137
3138 * ARP requests had wrong destination hardware address.
3139
3140 ++ Other changes:
3141
3142 * struct eth_addr changed from u16_t[3] array to u8_t[6].
3143
3144 * A ->linkoutput() member was added to struct netif.
3145
3146 * TCP and UDP ->dest_* struct members where changed to ->remote_*.
3147
3148 * ntoh* macros are now null definitions for big endian CPUs.
3149
3150(0.5.0) Changes since version 0.4.2
3151
3152 ++ New features:
3153
3154 * Redesigned operating system emulation layer to make porting easier.
3155
3156 * Better control over TCP output buffers.
3157
3158 * Documenation added.
3159
3160 ++ Bugfixes:
3161
3162 * Locking issues in buffer management.
3163
3164 * Bugfixes in the sequential API.
3165
3166 * IP forwarding could cause memory leakage. This has been fixed.
3167
3168 ++ Other changes:
3169
3170 * Directory structure somewhat changed; the core/ tree has been
3171 collapsed.
3172
3173(0.4.2) Changes since version 0.4.1
3174
3175 ++ New features:
3176
3177 * Experimental ARP implementation added.
3178
3179 * Skeleton Ethernet driver added.
3180
3181 * Experimental BSD socket API library added.
3182
3183 ++ Bugfixes:
3184
3185 * In very intense situations, memory leakage could occur. This has
3186 been fixed.
3187
3188 ++ Other changes:
3189
3190 * Variables named "data" and "code" have been renamed in order to
3191 avoid name conflicts in certain compilers.
3192
3193 * Variable++ have in appliciable cases been translated to ++variable
3194 since some compilers generate better code in the latter case.
3195
3196(0.4.1) Changes since version 0.4
3197
3198 ++ New features:
3199
3200 * TCP: Connection attempts time out earlier than data
3201 transmissions. Nagle algorithm implemented. Push flag set on the
3202 last segment in a burst.
3203
3204 * UDP: experimental support for UDP-Lite extensions.
3205
3206 ++ Bugfixes:
3207
3208 * TCP: out of order segments were in some cases handled incorrectly,
3209 and this has now been fixed. Delayed acknowledgements was broken
3210 in 0.4, has now been fixed. Binding to an address that is in use
3211 now results in an error. Reset connections sometimes hung an
3212 application; this has been fixed.
3213
3214 * Checksum calculation sometimes failed for chained pbufs with odd
3215 lengths. This has been fixed.
3216
3217 * API: a lot of bug fixes in the API. The UDP API has been improved
3218 and tested. Error reporting and handling has been
3219 improved. Logical flaws and race conditions for incoming TCP
3220 connections has been found and removed.
3221
3222 * Memory manager: alignment issues. Reallocating memory sometimes
3223 failed, this has been fixed.
3224
3225 * Generic library: bcopy was flawed and has been fixed.
3226
3227 ++ Other changes:
3228
3229 * API: all datatypes has been changed from generic ones such as
3230 ints, to specified ones such as u16_t. Functions that return
3231 errors now have the correct type (err_t).
3232
3233 * General: A lot of code cleaned up and debugging code removed. Many
3234 portability issues have been fixed.
3235
3236 * The license was changed; the advertising clause was removed.
3237
3238 * C64 port added.
3239
3240 * Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri
3241 Kosunen, Mikael Caleres, and Frits Wilmink for reporting and
3242 fixing bugs!
3243
3244(0.4) Changes since version 0.3.1
3245
3246 * Memory management has been radically changed; instead of
3247 allocating memory from a shared heap, memory for objects that are
3248 rapidly allocated and deallocated is now kept in pools. Allocation
3249 and deallocation from those memory pools is very fast. The shared
3250 heap is still present but is used less frequently.
3251
3252 * The memory, memory pool, and packet buffer subsystems now support
3253 4-, 2-, or 1-byte alignment.
3254
3255 * "Out of memory" situations are handled in a more robust way.
3256
3257 * Stack usage has been reduced.
3258
3259 * Easier configuration of lwIP parameters such as memory usage,
3260 TTLs, statistics gathering, etc. All configuration parameters are
3261 now kept in a single header file "lwipopts.h".
3262
3263 * The directory structure has been changed slightly so that all
3264 architecture specific files are kept under the src/arch
3265 hierarchy.
3266
3267 * Error propagation has been improved, both in the protocol modules
3268 and in the API.
3269
3270 * The code for the RTXC architecture has been implemented, tested
3271 and put to use.
3272
3273 * Bugs have been found and corrected in the TCP, UDP, IP, API, and
3274 the Internet checksum modules.
3275
3276 * Bugs related to porting between a 32-bit and a 16-bit architecture
3277 have been found and corrected.
3278
3279 * The license has been changed slightly to conform more with the
3280 original BSD license, including the advertisement clause.
3281
3282(0.3.1) Changes since version 0.3
3283
3284 * Fix of a fatal bug in the buffer management. Pbufs with allocated
3285 RAM never returned the RAM when the pbuf was deallocated.
3286
3287 * TCP congestion control, window updates and retransmissions did not
3288 work correctly. This has now been fixed.
3289
3290 * Bugfixes in the API.
3291
3292(0.3) Changes since version 0.2
3293
3294 * New and improved directory structure. All include files are now
3295 kept in a dedicated include/ directory.
3296
3297 * The API now has proper error handling. A new function,
3298 netconn_err(), now returns an error code for the connection in
3299 case of errors.
3300
3301 * Improvements in the memory management subsystem. The system now
3302 keeps a pointer to the lowest free memory block. A new function,
3303 mem_malloc2() tries to allocate memory once, and if it fails tries
3304 to free some memory and retry the allocation.
3305
3306 * Much testing has been done with limited memory
3307 configurations. lwIP now does a better job when overloaded.
3308
3309 * Some bugfixes and improvements to the buffer (pbuf) subsystem.
3310
3311 * Many bugfixes in the TCP code:
3312
3313 - Fixed a bug in tcp_close().
3314
3315 - The TCP receive window was incorrectly closed when out of
3316 sequence segments was received. This has been fixed.
3317
3318 - Connections are now timed-out of the FIN-WAIT-2 state.
3319
3320 - The initial congestion window could in some cases be too
3321 large. This has been fixed.
3322
3323 - The retransmission queue could in some cases be screwed up. This
3324 has been fixed.
3325
3326 - TCP RST flag now handled correctly.
3327
3328 - Out of sequence data was in some cases never delivered to the
3329 application. This has been fixed.
3330
3331 - Retransmitted segments now contain the correct acknowledgment
3332 number and advertised window.

3334 - TCP retransmission timeout backoffs are not correctly computed
3335 (ala BSD). After a number of retransmissions, TCP now gives up
3336 the connection.
3337
3338 * TCP connections now are kept on three lists, one for active
3339 connections, one for listening connections, and one for
3340 connections that are in TIME-WAIT. This greatly speeds up the fast
3341 timeout processing for sending delayed ACKs.
3342
3343 * TCP now provides proper feedback to the application when a
3344 connection has been successfully set up.
3345
3346 * More comments have been added to the code. The code has also been
3347 somewhat cleaned up.
