kevman 0:38ceb79fef03 262 addresses on multiple netifs should now be working correctly (if correctly
kevman 0:38ceb79fef03 263 addressed by routing, that is)
kevman 0:38ceb79fef03 264
kevman 0:38ceb79fef03 265 2015-03-23: Simon Goldschmidt
kevman 0:38ceb79fef03 266 * etharp.c: Stable etharp entries that are about to expire are now refreshed
kevman 0:38ceb79fef03 267 using unicast to prevent unnecessary broadcast. Only if no answer is received
kevman 0:38ceb79fef03 268 after 15 seconds, broadcast is used.

kevman 0:38ceb79fef03 270 2015-03-06: Philip Gladstone
kevman 0:38ceb79fef03 271 * netif.h/.c: patch #8359 (Provide utility function to add an IPv6 address to
kevman 0:38ceb79fef03 272 an interface)
kevman 0:38ceb79fef03 273
kevman 0:38ceb79fef03 274 2015-03-05: Simon Goldschmidt
kevman 0:38ceb79fef03 275 * netif.c, ip4.c, dhcp.c, autoip.c: fixed bug #37068 (netif up/down handling
kevman 0:38ceb79fef03 276 is unclear): correclty separated administrative status of a netif (up/down)
kevman 0:38ceb79fef03 277 from 'valid address' status
kevman 0:38ceb79fef03 278 ATTENTION: netif_set_up() now always has to be called, even when dhcp/autoip
kevman 0:38ceb79fef03 279 is used!
kevman 0:38ceb79fef03 280
kevman 0:38ceb79fef03 281 2015-02-26: patch by TabascoEye

kevman 0:38ceb79fef03 334 2015-01-17: Simon Goldschmidt
kevman 0:38ceb79fef03 335 * api: allow enabling socket API without (public) netconn API - netconn API is
kevman 0:38ceb79fef03 336 still used by sockets, but keeping it private (static) should allow better
kevman 0:38ceb79fef03 337 compiler optimizations

kevman 0:38ceb79fef03 398 2012-08-22: Sylvain Rochet
kevman 0:38ceb79fef03 399 * New PPP stack for lwIP, developed in ppp-new branch.
kevman 0:38ceb79fef03 400 Based from pppd 2.4.5, released 2009-11-17, with huge changes to match
kevman 0:38ceb79fef03 401 code size and memory requirements for embedded devices, including:
kevman 0:38ceb79fef03 402 - Gluing together the previous low-level PPP code in lwIP to pppd 2.4.5, which
kevman 0:38ceb79fef03 403 is more or less what pppd sys-* files are, so that we get something working
kevman 0:38ceb79fef03 404 using the unix port.
kevman 0:38ceb79fef03 405 - Merged some patchs from lwIP Git repository which add interesting features
kevman 0:38ceb79fef03 406 or fix bugs.
kevman 0:38ceb79fef03 407 - Merged some patchs from Debian pppd package which add interesting features
kevman 0:38ceb79fef03 408 or fix bugs.
kevman 0:38ceb79fef03 409 - Ported PPP timeout handling to the lwIP timers system
kevman 0:38ceb79fef03 410 - Disabled all the PPP code using filesystem access, replaced in necessary cases
kevman 0:38ceb79fef03 411 to configuration variables.
kevman 0:38ceb79fef03 412 - Disabled all the PPP code forking processes.
kevman 0:38ceb79fef03 413 - Removed IPX support, lwIP does not support IPX.
kevman 0:38ceb79fef03 414 - Ported and improved random module from the previous PPP port.
kevman 0:38ceb79fef03 415 - Removed samba TDB (file-driven database) usage, because it needs a filesystem.
kevman 0:38ceb79fef03 416 - MS-CHAP required a DES implementation, we added the latest PolarSSL DES
kevman 0:38ceb79fef03 417 implementation which is under a BSD-ish license.
kevman 0:38ceb79fef03 418 - Also switched to PolarSSL MD4,MD5,SHA1 implementations, which are meant to be
kevman 0:38ceb79fef03 419 used in embedded devices with reduced memory footprint.
kevman 0:38ceb79fef03 420 - Removed PPP configuration file parsing support.
kevman 0:38ceb79fef03 421 - Added macro definition EAP_SUPPORT to make EAP support optional.
kevman 0:38ceb79fef03 422 - Added macro definition CHAP_SUPPORT to make CHAP support optional.
kevman 0:38ceb79fef03 423 - Added macro definition MSCHAP_SUPPORT to make MSCHAP support optional.

kevman 0:38ceb79fef03 425 - Cleared all Linux syscall calls.
kevman 0:38ceb79fef03 426 - Disabled demand support using a macro, so that it can be ported later.
kevman 0:38ceb79fef03 427 - Disabled ECP support using a macro, so that it can be ported later.
kevman 0:38ceb79fef03 428 - Disabled CCP support using a macro, so that it can be ported later.
kevman 0:38ceb79fef03 429 - Disabled CBCP support using a macro, so that it can be ported later.
kevman 0:38ceb79fef03 430 - Disabled LQR support using a macro, so that it can be ported later.
kevman 0:38ceb79fef03 431 - Print packet debug feature optional, through PRINTPKT_SUPPORT
kevman 0:38ceb79fef03 432 - Removed POSIX signal usage.
kevman 0:38ceb79fef03 433 - Fully ported PPPoS code from the previous port.
kevman 0:38ceb79fef03 434 - Fully ported PPPoE code from the previous port.
kevman 0:38ceb79fef03 435 - Fully ported VJ compression protocol code from the previous port.
kevman 0:38ceb79fef03 436 - Removed all malloc()/free() use from PPP, replaced by stack usage or PBUF.
kevman 0:38ceb79fef03 437 - Disabled PPP server support using a macro, so that it can be ported later.
kevman 0:38ceb79fef03 438 - Switched all PPP debug to lwIP debug system.
kevman 0:38ceb79fef03 439 - Created PPP Control Block (PPP PCB), removed PPP unit integer everywhere,
kevman 0:38ceb79fef03 440 removed all global variables everywhere, did everything necessary for
kevman 0:38ceb79fef03 441 the PPP stack to support more than one PPP session (pppd only support
kevman 0:38ceb79fef03 442 one session per process).
kevman 0:38ceb79fef03 443 - Removed the statically allocated output buffer, now using PBUF.
kevman 0:38ceb79fef03 444 - Improved structure size of all PPP modules, deep analyze of code to reduce
kevman 0:38ceb79fef03 445 variables size to the bare minimum. Switched all boolean type (char type in
kevman 0:38ceb79fef03 446 most architecture) to compiler generated bitfields.
kevman 0:38ceb79fef03 447 - Added PPP IPv6 support, glued lwIP IPv6 support to PPP.
kevman 0:38ceb79fef03 448 - Now using a persistent netif interface which can then be used in lwIP
kevman 0:38ceb79fef03 449 functions requiring a netif.
kevman 0:38ceb79fef03 450 - Now initializing PPP in lwip_init() function.
kevman 0:38ceb79fef03 451 - Reworked completely the PPP state machine, so that we don't end up in
kevman 0:38ceb79fef03 452 anymore in inconsistent state, especially with PPPoE.
kevman 0:38ceb79fef03 453 - Improved the way we handle PPP reconnection after disconnect, cleaning
kevman 0:38ceb79fef03 454 everything required so that we start the PPP connection again from a
kevman 0:38ceb79fef03 455 clean state.
kevman 0:38ceb79fef03 456 - Added PPP holdoff support, allow the lwIP user to wait a little bit before
kevman 0:38ceb79fef03 457 reconnecting, prevents connection flood, especially when using PPPoL2TP.
kevman 0:38ceb79fef03 458 - Added PPPoL2TP LAC support (a.k.a. UDP tunnels), adding a VPN client
kevman 0:38ceb79fef03 459 feature to lwIP, L2TP being a widely used tunnel protocol.
kevman 0:38ceb79fef03 460 - Switched all used PPP types to lwIP types (u8t, u16t, u32t, ...)
kevman 0:38ceb79fef03 461 - Added PPP API "sequential" thread-safe API, based from NETIFAPI.
kevman 0:38ceb79fef03 462
kevman 0:38ceb79fef03 463 2011-07-21: Simon Goldschmidt
kevman 0:38ceb79fef03 464 * sockets.c, opt.h: (bug #30185): added LWIP_FIONREAD_LINUXMODE that makes

kevman 0:38ceb79fef03 466
kevman 0:38ceb79fef03 467 2011-05-25: Simon Goldschmidt
kevman 0:38ceb79fef03 468 * again nearly the whole stack, renamed ip.c to ip4.c, ip_addr.c to ip4_addr.c,
kevman 0:38ceb79fef03 469 combined ipv4/ipv6 inet_chksum.c, added ip.h, ip_addr.h: Combined IPv4
kevman 0:38ceb79fef03 470 and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP
kevman 0:38ceb79fef03 471 code so that the code is more readable.
kevman 0:38ceb79fef03 472
kevman 0:38ceb79fef03 473 2011-05-17: Patch by Ivan Delamer (only checked in by Simon Goldschmidt)
kevman 0:38ceb79fef03 474 * nearly the whole stack: Finally, we got decent IPv6 support, big thanks to
kevman 0:38ceb79fef03 475 Ivan! (this is work in progress: we're just post release anyway :-)

kevman 0:38ceb79fef03 517 2016-03-22: Simon Goldschmidt
kevman 0:38ceb79fef03 518 * tcp: changed accept handling to be done internally: the application does not
kevman 0:38ceb79fef03 519 have to call tcp_accepted() any more. Instead, when delaying accept (e.g. sockets
kevman 0:38ceb79fef03 520 do), call tcp_backlog_delayed()/tcp_backlog_accepted() (fixes bug #46696)

kevman 0:38ceb79fef03 529 2016-03-17: Joel Cunningham
kevman 0:38ceb79fef03 530 * api_msg.c: don't fail closing a socket/netconn when failing to allocate the
kevman 0:38ceb79fef03 531 FIN segment; blocking the calling thread for a while is better than risking
kevman 0:38ceb79fef03 532 leaking a netconn/socket (see bug #46701)

kevman 0:38ceb79fef03 1262 link-layer-addressed UDP traffic to be received while a netif is down (just
kevman 0:38ceb79fef03 1263 like DHCP during configuration)
kevman 0:38ceb79fef03 1264
kevman 0:38ceb79fef03 1265 2010-05-22: Simon Goldschmidt
kevman 0:38ceb79fef03 1266 * many many files: bug #27352: removed packing from ip_addr_t, the packed
kevman 0:38ceb79fef03 1267 version is now only used in protocol headers. Added global storage for
kevman 0:38ceb79fef03 1268 current src/dest IP address while in input functions.

kevman 0:38ceb79fef03 1274 2010-05-16: Simon Goldschmidt
kevman 0:38ceb79fef03 1275 * opt.h, memp_std.h, memp.c, ppp_oe.h/.c: PPPoE now uses its own MEMP pool

kevman 0:38ceb79fef03 1290
kevman 0:38ceb79fef03 1291 2010-04-30: Simon Goldschmidt
kevman 0:38ceb79fef03 1292 * udp.h/.c, pbuf.h/.c: task #6849: added udp_send(_to/_if) functions that
kevman 0:38ceb79fef03 1293 take a precalculated checksum, added pbuf_fill_chksum() to copy data
kevman 0:38ceb79fef03 1294 into a pbuf and at the same time calculating the checksum for that data
kevman 0:38ceb79fef03 1295
kevman 0:38ceb79fef03 1296 2010-04-29: Simon Goldschmidt

kevman 0:38ceb79fef03 1304 * tcpip.h/.c, timers.c: Added an overridable define to get informed when the
kevman 0:38ceb79fef03 1305 tcpip_thread processes messages or timeouts to implement a watchdog.
kevman 0:38ceb79fef03 1306
kevman 0:38ceb79fef03 1307 2010-03-28: Simon Goldschmidt
kevman 0:38ceb79fef03 1308 * ip_frag.c: create a new (contiguous) PBUF_RAM for every outgoing

kevman 0:38ceb79fef03 1310
kevman 0:38ceb79fef03 1311 2010-03-27: Simon Goldschmidt
kevman 0:38ceb79fef03 1312 * etharp.c: Speedup TX by moving code from find_entry to etharp_output/
kevman 0:38ceb79fef03 1313 etharp_query to prevent unnecessary function calls (inspired by
kevman 0:38ceb79fef03 1314 patch #7135).
kevman 0:38ceb79fef03 1315
kevman 0:38ceb79fef03 1316 2010-03-20: Simon Goldschmidt
kevman 0:38ceb79fef03 1317 * opt.h, tcpip.c/.h: Added an option to disable tcpip_(un)timeout code
kevman 0:38ceb79fef03 1318 since the linker cannot do this automatically to save space.
kevman 0:38ceb79fef03 1319
kevman 0:38ceb79fef03 1320 2010-03-20: Simon Goldschmidt
kevman 0:38ceb79fef03 1321 * opt.h, etharp.c/.h: Added support for static ARP table entries

kevman 0:38ceb79fef03 1323 2010-03-14: Simon Goldschmidt
kevman 0:38ceb79fef03 1324 * tcp_impl.h, tcp_out.c, inet_chksum.h/.c: task #6849: Calculate checksum
kevman 0:38ceb79fef03 1325 when creating TCP segments, not when (re-)transmitting them.
kevman 0:38ceb79fef03 1326
kevman 0:38ceb79fef03 1327 2010-03-07: Simon Goldschmidt
kevman 0:38ceb79fef03 1328 * sockets.c: bug #28775 (select/event_callback: only check select_cb_list
kevman 0:38ceb79fef03 1329 on change) plus use SYS_LIGHTWEIGHT_PROT to protect the select code.
kevman 0:38ceb79fef03 1330 This should speed up receiving data on sockets as the select code in
kevman 0:38ceb79fef03 1331 event_callback is only executed when select is waiting.
kevman 0:38ceb79fef03 1332
kevman 0:38ceb79fef03 1333 2010-03-06: Simon Goldschmidt
kevman 0:38ceb79fef03 1334 * tcp_out.c: task #7013 (Create option to have all packets delivered to
kevman 0:38ceb79fef03 1335 netif->output in one piece): Always copy to try to create single pbufs
kevman 0:38ceb79fef03 1336 in tcp_write.
kevman 0:38ceb79fef03 1337
kevman 0:38ceb79fef03 1338 2010-03-06: Simon Goldschmidt
kevman 0:38ceb79fef03 1339 * api.h, api_lib.c, sockets.c: task #10167 (sockets: speed up TCP recv
kevman 0:38ceb79fef03 1340 by not allocating a netbuf): added function netconn_recv_tcp_pbuf()
kevman 0:38ceb79fef03 1341 for tcp netconns to receive pbufs, not netbufs; use that function
kevman 0:38ceb79fef03 1342 for tcp sockets.

kevman 0:38ceb79fef03 1344 2010-03-05: Jakob Ole Stoklundsen / Simon Goldschmidt
kevman 0:38ceb79fef03 1345 * opt.h, tcp.h, tcp_impl.h, tcp.c, tcp_in.c, tcp_out.c: task #7040:
kevman 0:38ceb79fef03 1346 Work on tcp_enqueue: Don't waste memory when chaining segments,
kevman 0:38ceb79fef03 1347 added option TCP_OVERSIZE to prevent creating many small pbufs when
kevman 0:38ceb79fef03 1348 calling tcp_write with many small blocks of data. Instead, pbufs are
kevman 0:38ceb79fef03 1349 allocated larger than needed and the space is used for later calls to
kevman 0:38ceb79fef03 1350 tcp_write.
kevman 0:38ceb79fef03 1351
kevman 0:38ceb79fef03 1352 2010-02-21: Simon Goldschmidt

kevman 0:38ceb79fef03 1355
kevman 0:38ceb79fef03 1356 2010-02-21: Simon Goldschmidt
kevman 0:38ceb79fef03 1357 * tcp.h (and usages), added tcp_impl.h: Splitted API and internal
kevman 0:38ceb79fef03 1358 implementation of tcp to make API usage cleare to application programmers
kevman 0:38ceb79fef03 1359
kevman 0:38ceb79fef03 1360 2010-02-14: Simon Goldschmidt/Stephane Lesage

kevman 0:38ceb79fef03 1372 2010-02-12: Simon Goldschmidt
kevman 0:38ceb79fef03 1373 * dhcp.c/.h, autoip.c/.h: task #10139 (Prefer statically allocated
kevman 0:38ceb79fef03 1374 memory): added autoip_set_struct() and dhcp_set_struct() to let autoip
kevman 0:38ceb79fef03 1375 and dhcp work with user-allocated structs instead of callin mem_malloc
kevman 0:38ceb79fef03 1376
kevman 0:38ceb79fef03 1377 2010-02-12: Simon Goldschmidt/Jeff Barber
kevman 0:38ceb79fef03 1378 * tcp.c/h: patch #6865 (SO_REUSEADDR for TCP): if pcb.so_options has

kevman 0:38ceb79fef03 1387
kevman 0:38ceb79fef03 1388 2010-02-09: Simon Goldschmidt (Simon Kallweit)
kevman 0:38ceb79fef03 1389 * timers.c/.h: Added function sys_restart_timeouts() from patch #7085
kevman 0:38ceb79fef03 1390 (Restart system timeout handling)
kevman 0:38ceb79fef03 1391
kevman 0:38ceb79fef03 1392 2010-02-09: Simon Goldschmidt
kevman 0:38ceb79fef03 1393 * netif.c/.h, removed loopif.c/.h: task #10153 (Integrate loopif into
kevman 0:38ceb79fef03 1394 netif.c) - loopif does not have to be created by the port any more,

kevman 0:38ceb79fef03 1407 2010-02-04: Simon Goldschmidt
kevman 0:38ceb79fef03 1408 * nearly every file: Replaced struct ip_addr by typedef ip_addr_t to
kevman 0:38ceb79fef03 1409 make changing the actual implementation behind the typedef easier.
kevman 0:38ceb79fef03 1410
kevman 0:38ceb79fef03 1411 2010-02-01: Simon Goldschmidt

kevman 0:38ceb79fef03 1414
kevman 0:38ceb79fef03 1415 2010-01-31: Simon Goldschmidt
kevman 0:38ceb79fef03 1416 * dhcp.h, dhcp.c: Reworked the code that parses DHCP options: parse
kevman 0:38ceb79fef03 1417 them once instead of parsing for every option. This also removes
kevman 0:38ceb79fef03 1418 the need for mem_malloc from dhcp_recv and makes it possible to
kevman 0:38ceb79fef03 1419 correctly retrieve the BOOTP file.

kevman 0:38ceb79fef03 1787 2010-02-04: Simon Goldschmidt
kevman 0:38ceb79fef03 1788 * nearly every file: Use macros defined in ip_addr.h (some of them new)
kevman 0:38ceb79fef03 1789 to work with IP addresses (preparation for bug #27352 - Change ip_addr
kevman 0:38ceb79fef03 1790 from struct to typedef (u32_t) - and better code).
kevman 0:38ceb79fef03 1791

kevman 0:38ceb79fef03 1793 * netif.c: Don't call the link-callback from netif_set_up/down() since

kevman 0:38ceb79fef03 1798 portability file inet.h and its contents from the stack: moved htonX-
kevman 0:38ceb79fef03 1799 functions to def.h (and the new def.c - they are not ipv4 dependent),
kevman 0:38ceb79fef03 1800 let inet.h depend on ip_addr.h and not the other way round.
kevman 0:38ceb79fef03 1801 This fixes bug #28732.

kevman 0:38ceb79fef03 1810
kevman 0:38ceb79fef03 1811 2010-01-25: Simon Goldschmidt

kevman 0:38ceb79fef03 1816 2010-01-24: Simon Goldschmidt
kevman 0:38ceb79fef03 1817 * snmp: Renamed the private mib node from 'private' to 'mib_private' to

kevman 0:38ceb79fef03 2466 Introduce changes for task #7490 "Add return value to sys_mbox_post" with some
kevman 0:38ceb79fef03 2467 modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which
kevman 0:38ceb79fef03 2468 indicate the number of pointers query by the mailbox. There is three defines
kevman 0:38ceb79fef03 2469 in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the
kevman 0:38ceb79fef03 2470 netconn::acceptmbox. Port maintainers, you can decide to just add this new
kevman 0:38ceb79fef03 2471 parameter in your implementation, but to ignore it to keep the previous behavior.
kevman 0:38ceb79fef03 2472 The new sys_mbox_trypost function return a value to know if the mailbox is
kevman 0:38ceb79fef03 2473 full or if the message is posted. Take a look to sys_arch.txt for more details.
kevman 0:38ceb79fef03 2474 This new function is used in tcpip_input (so, can be called in an interrupt
kevman 0:38ceb79fef03 2475 context since the function is not blocking), and in recv_udp and recv_raw.

kevman 0:38ceb79fef03 2486 2007-12-31 Frédéric Bernon, Luca Ceresoli
kevman 0:38ceb79fef03 2487 * autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP packets
kevman 0:38ceb79fef03 2488 in autoip". The change in etharp_raw could be removed, since all calls to
kevman 0:38ceb79fef03 2489 etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be
kevman 0:38ceb79fef03 2490 wrong in the future.
kevman 0:38ceb79fef03 2491
kevman 0:38ceb79fef03 2492 2007-12-30 Frédéric Bernon, Tom Evans
kevman 0:38ceb79fef03 2493 * ip.c: Fix bug #21846 "LwIP doesn't appear to perform any IP Source Address
kevman 0:38ceb79fef03 2494 Filtering" reported by Tom Evans.
kevman 0:38ceb79fef03 2495
kevman 0:38ceb79fef03 2496 2007-12-21 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
kevman 0:38ceb79fef03 2497 * tcp.h, opt.h, api.h, api_msg.h, tcp.c, tcp_in.c, api_lib.c, api_msg.c,
kevman 0:38ceb79fef03 2498 sockets.c, init.c: task #7252: Implement TCP listen backlog: Warning: raw API
kevman 0:38ceb79fef03 2499 applications have to call 'tcp_accepted(pcb)' in their accept callback to
kevman 0:38ceb79fef03 2500 keep accepting new connections.
kevman 0:38ceb79fef03 2501
kevman 0:38ceb79fef03 2502 2007-12-13 Frédéric Bernon
kevman 0:38ceb79fef03 2503 * api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum dns_result"
kevman 0:38ceb79fef03 2504 by err_t type. Add a new err_t code "ERR_INPROGRESS".
kevman 0:38ceb79fef03 2505
kevman 0:38ceb79fef03 2506 2007-12-12 Frédéric Bernon
kevman 0:38ceb79fef03 2507 * dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles
kevman 0:38ceb79fef03 2508 are the one which have ram usage.
kevman 0:38ceb79fef03 2509
kevman 0:38ceb79fef03 2510 2007-12-05 Frédéric Bernon
kevman 0:38ceb79fef03 2511 * netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static
kevman 0:38ceb79fef03 2512 set of variables (=0) or a local one (=1). In this last case, your port should
kevman 0:38ceb79fef03 2513 provide a function "struct hostent* sys_thread_hostent( struct hostent* h)"
kevman 0:38ceb79fef03 2514 which have to do a copy of "h" and return a pointer ont the "per-thread" copy.
kevman 0:38ceb79fef03 2515
kevman 0:38ceb79fef03 2516 2007-12-03 Simon Goldschmidt
kevman 0:38ceb79fef03 2517 * ip.c: ip_input: check if a packet is for inp first before checking all other
kevman 0:38ceb79fef03 2518 netifs on netif_list (speeds up packet receiving in most cases)
kevman 0:38ceb79fef03 2519
kevman 0:38ceb79fef03 2520 2007-11-30 Simon Goldschmidt
kevman 0:38ceb79fef03 2521 * udp.c, raw.c: task #7497: Sort lists (pcb, netif, ...) for faster access
kevman 0:38ceb79fef03 2522 UDP: move a (connected) pcb selected for input to the front of the list of
kevman 0:38ceb79fef03 2523 pcbs so that it is found faster next time. Same for RAW pcbs that have eaten
kevman 0:38ceb79fef03 2524 a packet.
kevman 0:38ceb79fef03 2525
kevman 0:38ceb79fef03 2526 2007-11-28 Simon Goldschmidt
kevman 0:38ceb79fef03 2527 * etharp.c, stats.c, stats.h, opt.h: Introduced ETHARP_STATS
kevman 0:38ceb79fef03 2528
kevman 0:38ceb79fef03 2529 2007-11-25 Simon Goldschmidt
kevman 0:38ceb79fef03 2530 * dhcp.c: dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy
kevman 0:38ceb79fef03 2531 algorithm.
kevman 0:38ceb79fef03 2532
kevman 0:38ceb79fef03 2533 2007-11-24 Simon Goldschmidt
kevman 0:38ceb79fef03 2534 * netdb.h, netdb.c, sockets.h/.c: Moved lwip_gethostbyname from sockets.c
kevman 0:38ceb79fef03 2535 to the new file netdb.c; included lwip_getaddrinfo.
kevman 0:38ceb79fef03 2536
kevman 0:38ceb79fef03 2537 2007-11-21 Simon Goldschmidt
kevman 0:38ceb79fef03 2538 * tcp.h, opt.h, tcp.c, tcp_in.c: implemented calculating the effective send-mss
kevman 0:38ceb79fef03 2539 based on the MTU of the netif used to send. Enabled by default. Disable by
kevman 0:38ceb79fef03 2540 setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21492.
kevman 0:38ceb79fef03 2541
kevman 0:38ceb79fef03 2542 2007-11-19 Frédéric Bernon
kevman 0:38ceb79fef03 2543 * api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name
kevman 0:38ceb79fef03 2544 received match the name query), implement DNS_USES_STATIC_BUF (the place where
kevman 0:38ceb79fef03 2545 copy dns payload to parse the response), return an error if there is no place
kevman 0:38ceb79fef03 2546 for a new query, and fix some minor problems.
kevman 0:38ceb79fef03 2547
kevman 0:38ceb79fef03 2548 2007-11-16 Simon Goldschmidt
kevman 0:38ceb79fef03 2549 * new files: ipv4/inet.c, ipv4/inet_chksum.c, ipv6/inet6.c
kevman 0:38ceb79fef03 2550 removed files: core/inet.c, core/inet6.c
kevman 0:38ceb79fef03 2551 Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into
kevman 0:38ceb79fef03 2552 inet and chksum part; changed includes in all lwIP files as appropriate
kevman 0:38ceb79fef03 2553
kevman 0:38ceb79fef03 2554 2007-11-16 Simon Goldschmidt
kevman 0:38ceb79fef03 2555 * api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential
kevman 0:38ceb79fef03 2556 dns resolver function for netconn api (netconn_gethostbyname) and socket api
kevman 0:38ceb79fef03 2557 (gethostbyname/gethostbyname_r).
kevman 0:38ceb79fef03 2558
kevman 0:38ceb79fef03 2559 2007-11-15 Jim Pettinato, Frédéric Bernon
kevman 0:38ceb79fef03 2560 * opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name
kevman 0:38ceb79fef03 2561 requests with RAW api interface. Initialization is done in lwip_init() with
kevman 0:38ceb79fef03 2562 build time options. DNS timer is added in tcpip_thread context. DHCP can set
kevman 0:38ceb79fef03 2563 DNS server ip addresses when options are received. You need to set LWIP_DNS=1
kevman 0:38ceb79fef03 2564 in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get
kevman 0:38ceb79fef03 2565 some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo"
kevman 0:38ceb79fef03 2566 list with points to improve.
kevman 0:38ceb79fef03 2567
kevman 0:38ceb79fef03 2568 2007-11-06 Simon Goldschmidt
kevman 0:38ceb79fef03 2569 * opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly
kevman 0:38ceb79fef03 2570 enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status
kevman 0:38ceb79fef03 2571 for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.
kevman 0:38ceb79fef03 2572
kevman 0:38ceb79fef03 2573 2007-11-06 Simon Goldschmidt
kevman 0:38ceb79fef03 2574 * api.h, api_msg.h and dependent files: Task #7410: Removed the need to include
kevman 0:38ceb79fef03 2575 core header files in api.h (ip/tcp/udp/raw.h) to hide the internal
kevman 0:38ceb79fef03 2576 implementation from netconn api applications.
kevman 0:38ceb79fef03 2577
kevman 0:38ceb79fef03 2578 2007-11-03 Frédéric Bernon
kevman 0:38ceb79fef03 2579 * api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP &
kevman 0:38ceb79fef03 2580 RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled
kevman 0:38ceb79fef03 2581 by default). Netconn API users can use the netconn_recv_bufsize macro to access
kevman 0:38ceb79fef03 2582 it. This is a first release which have to be improve for TCP. Note it used the
kevman 0:38ceb79fef03 2583 netconn::recv_avail which need to be more "thread-safe" (note there is already
kevman 0:38ceb79fef03 2584 the problem for FIONREAD with lwip_ioctl/ioctlsocket).
kevman 0:38ceb79fef03 2585
kevman 0:38ceb79fef03 2586 2007-11-01 Frédéric Bernon, Marc Chaland
kevman 0:38ceb79fef03 2587 * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c:
kevman 0:38ceb79fef03 2588 Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api
kevman 0:38ceb79fef03 2589 layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api
kevman 0:38ceb79fef03 2590 layer. This option enable to delayed TCP PUSH flag on multiple "write" calls.
kevman 0:38ceb79fef03 2591 Note that previous "copy" parameter for "write" APIs is now called "apiflags".
kevman 0:38ceb79fef03 2592
kevman 0:38ceb79fef03 2593 2007-10-24 Frédéric Bernon
kevman 0:38ceb79fef03 2594 * api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than
kevman 0:38ceb79fef03 2595 TCP_EVENT_xxx macros to get a code more readable. It could also help to remove
kevman 0:38ceb79fef03 2596 some code (like we have talk in "patch #5919 : Create compile switch to remove
kevman 0:38ceb79fef03 2597 select code"), but it could be done later.
kevman 0:38ceb79fef03 2598
kevman 0:38ceb79fef03 2599 2007-10-08 Simon Goldschmidt
kevman 0:38ceb79fef03 2600 * many files: Changed initialization: many init functions are not needed any
kevman 0:38ceb79fef03 2601 more since we now rely on the compiler initializing global and static
kevman 0:38ceb79fef03 2602 variables to zero!
kevman 0:38ceb79fef03 2603
kevman 0:38ceb79fef03 2604 2007-10-06 Simon Goldschmidt
kevman 0:38ceb79fef03 2605 * ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY
kevman 0:38ceb79fef03 2606 to enqueue the received pbufs so that multiple packets can be reassembled
kevman 0:38ceb79fef03 2607 simultaneously and no static reassembly buffer is needed.
kevman 0:38ceb79fef03 2608
kevman 0:38ceb79fef03 2609 2007-10-05 Simon Goldschmidt
kevman 0:38ceb79fef03 2610 * tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so
kevman 0:38ceb79fef03 2611 all netifs (or ports) can use it.
kevman 0:38ceb79fef03 2612
kevman 0:38ceb79fef03 2613 2007-10-05 Frédéric Bernon
kevman 0:38ceb79fef03 2614 * netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the
kevman 0:38ceb79fef03 2615 common function to reduce a little bit the footprint (for all functions using
kevman 0:38ceb79fef03 2616 only the "netif" parameter).
kevman 0:38ceb79fef03 2617
kevman 0:38ceb79fef03 2618 2007-10-03 Frédéric Bernon
kevman 0:38ceb79fef03 2619 * netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down,
kevman 0:38ceb79fef03 2620 netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce
kevman 0:38ceb79fef03 2621 a little bit the footprint (for all functions using only the "netif" parameter).
kevman 0:38ceb79fef03 2622
kevman 0:38ceb79fef03 2623 2007-09-15 Frédéric Bernon
kevman 0:38ceb79fef03 2624 * udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF
kevman 0:38ceb79fef03 2625 option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for
kevman 0:38ceb79fef03 2626 netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for
kevman 0:38ceb79fef03 2627 IP_MULTICAST_TTL and IP_MULTICAST_IF.
kevman 0:38ceb79fef03 2628
kevman 0:38ceb79fef03 2629 2007-09-10 Frédéric Bernon
kevman 0:38ceb79fef03 2630 * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles
kevman 0:38ceb79fef03 2631 even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime()
kevman 0:38ceb79fef03 2632 each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can
kevman 0:38ceb79fef03 2633 decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but
kevman 0:38ceb79fef03 2634 call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime()
kevman 0:38ceb79fef03 2635 or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
kevman 0:38ceb79fef03 2636 This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
kevman 0:38ceb79fef03 2637 snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
kevman 0:38ceb79fef03 2638 when it's queried (any direct call to "sysuptime" is changed by a call to
kevman 0:38ceb79fef03 2639 snmp_get_sysuptime).
kevman 0:38ceb79fef03 2640
kevman 0:38ceb79fef03 2641 2007-09-09 Frédéric Bernon, Bill Florac
kevman 0:38ceb79fef03 2642 * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP,
kevman 0:38ceb79fef03 2643 and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags
kevman 0:38ceb79fef03 2644 if you want IGMP on an interface. igmp_stop() is now called inside netif_remove().
kevman 0:38ceb79fef03 2645 igmp_report_groups() is now called inside netif_set_link_up() (need to have
kevman 0:38ceb79fef03 2646 LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait
kevman 0:38ceb79fef03 2647 the next query message to receive the matching multicast streams).
kevman 0:38ceb79fef03 2648
kevman 0:38ceb79fef03 2649 2007-09-08 Frédéric Bernon
kevman 0:38ceb79fef03 2650 * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains
kevman 0:38ceb79fef03 2651 IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change).
kevman 0:38ceb79fef03 2652 Use this new field to access to common pcb fields (ttl, tos, so_options, etc...).
kevman 0:38ceb79fef03 2653 Enable to access to these fields with LWIP_TCP=0.
kevman 0:38ceb79fef03 2654
kevman 0:38ceb79fef03 2655 2007-09-05 Frédéric Bernon
kevman 0:38ceb79fef03 2656 * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h,
kevman 0:38ceb79fef03 2657 ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option
kevman 0:38ceb79fef03 2658 LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default).
kevman 0:38ceb79fef03 2659 Be careful, disabling ICMP make your product non-compliant to RFC1122, but
kevman 0:38ceb79fef03 2660 help to reduce footprint, and to reduce "visibility" on the Internet.
kevman 0:38ceb79fef03 2661
kevman 0:38ceb79fef03 2662 2007-09-05 Frédéric Bernon, Bill Florac
kevman 0:38ceb79fef03 2663 * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list
kevman 0:38ceb79fef03 2664 for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new
kevman 0:38ceb79fef03 2665 parameters have to be provided: a task name, and a task stack size. For this
kevman 0:38ceb79fef03 2666 one, since it's platform dependant, you could define the best one for you in
kevman 0:38ceb79fef03 2667 your lwipopts.h. For port maintainers, you can just add these new parameters
kevman 0:38ceb79fef03 2668 in your sys_arch.c file, and but it's not mandatory, use them in your OS
kevman 0:38ceb79fef03 2669 specific functions.
kevman 0:38ceb79fef03 2670
kevman 0:38ceb79fef03 2671 2007-09-05 Frédéric Bernon
kevman 0:38ceb79fef03 2672 * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings
kevman 0:38ceb79fef03 2673 inside init.c for task #7142 "Sanity check user-configurable values".
kevman 0:38ceb79fef03 2674
kevman 0:38ceb79fef03 2675 2007-09-04 Frédéric Bernon, Bill Florac
kevman 0:38ceb79fef03 2676 * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by
kevman 0:38ceb79fef03 2677 memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the
kevman 0:38ceb79fef03 2678 value). It will avoid potential fragmentation problems, use a counter to know
kevman 0:38ceb79fef03 2679 how many times a group is used on an netif, and free it when all applications
kevman 0:38ceb79fef03 2680 leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity
kevman 0:38ceb79fef03 2681 check if LWIP_IGMP!=0).
kevman 0:38ceb79fef03 2682
kevman 0:38ceb79fef03 2683 2007-09-03 Frédéric Bernon
kevman 0:38ceb79fef03 2684 * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement".
kevman 0:38ceb79fef03 2685 Initialize igmp_mac_filter to NULL in netif_add (this field should be set in
kevman 0:38ceb79fef03 2686 the netif's "init" function). Use the "imr_interface" field (for socket layer)
kevman 0:38ceb79fef03 2687 and/or the "interface" field (for netconn layer), for join/leave operations.
kevman 0:38ceb79fef03 2688 The igmp_join/leavegroup first parameter change from a netif to an ipaddr.
kevman 0:38ceb79fef03 2689 This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany).
kevman 0:38ceb79fef03 2690
kevman 0:38ceb79fef03 2691 2007-08-30 Frédéric Bernon
kevman 0:38ceb79fef03 2692 * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions
kevman 0:38ceb79fef03 2693 from api/api_lib". Now netbuf API is independant of netconn, and can be used
kevman 0:38ceb79fef03 2694 with other API (application based on raw API, or future "socket2" API). Ports
kevman 0:38ceb79fef03 2695 maintainers just have to add src/api/netbuf.c in their makefile/projects.
kevman 0:38ceb79fef03 2696
kevman 0:38ceb79fef03 2697 2007-08-30 Frédéric Bernon, Jonathan Larmour
kevman 0:38ceb79fef03 2698 * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check
kevman 0:38ceb79fef03 2699 user-configurable values".
kevman 0:38ceb79fef03 2700
kevman 0:38ceb79fef03 2701 2007-08-29 Frédéric Bernon
kevman 0:38ceb79fef03 2702 * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start.
kevman 0:38ceb79fef03 2703 igmp_start is call inside netif_add. Now, igmp initialization is in the same
kevman 0:38ceb79fef03 2704 spirit than the others modules. Modify some IGMP debug traces.

kevman 0:38ceb79fef03 2707 * Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function"
kevman 0:38ceb79fef03 2708 Add lwip_init function to regroup all modules initializations, and to provide
kevman 0:38ceb79fef03 2709 a place to add code for task #7142 "Sanity check user-configurable values".
kevman 0:38ceb79fef03 2710 Ports maintainers should remove direct initializations calls from their code,
kevman 0:38ceb79fef03 2711 and add init.c in their makefiles. Note that lwip_init() function is called
kevman 0:38ceb79fef03 2712 inside tcpip_init, but can also be used by raw api users since all calls are
kevman 0:38ceb79fef03 2713 disabled when matching options are disabled. Also note that their is new options
kevman 0:38ceb79fef03 2714 in opt.h, you should configure in your lwipopts.h (they are enabled per default).
kevman 0:38ceb79fef03 2715
kevman 0:38ceb79fef03 2716 2007-08-26 Marc Boucher
kevman 0:38ceb79fef03 2717 * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL
kevman 0:38ceb79fef03 2718 since they can under certain circumstances be called with an invalid conn
kevman 0:38ceb79fef03 2719 pointer after the connection has been closed (and conn has been freed).
kevman 0:38ceb79fef03 2720
kevman 0:38ceb79fef03 2721 2007-08-25 Frédéric Bernon (Artem Migaev's Patch)
kevman 0:38ceb79fef03 2722 * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up".
kevman 0:38ceb79fef03 2723 Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set.
kevman 0:38ceb79fef03 2724
kevman 0:38ceb79fef03 2725 2007-08-22 Frédéric Bernon
kevman 0:38ceb79fef03 2726 * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK
kevman 0:38ceb79fef03 2727 to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release.
kevman 0:38ceb79fef03 2728
kevman 0:38ceb79fef03 2729 2007-08-22 Frédéric Bernon
kevman 0:38ceb79fef03 2730 * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT &
kevman 0:38ceb79fef03 2731 ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the
kevman 0:38ceb79fef03 2732 name is tcpip_input (we keep the name of 1.2.0 function).
kevman 0:38ceb79fef03 2733
kevman 0:38ceb79fef03 2734 2007-08-17 Jared Grubb
kevman 0:38ceb79fef03 2735 * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool
kevman 0:38ceb79fef03 2736 settings into new memp_std.h and optional user file lwippools.h. This adds
kevman 0:38ceb79fef03 2737 more dynamic mempools, and allows the user to create an arbitrary number of
kevman 0:38ceb79fef03 2738 mempools for mem_malloc.
kevman 0:38ceb79fef03 2739
kevman 0:38ceb79fef03 2740 2007-08-16 Marc Boucher
kevman 0:38ceb79fef03 2741 * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function;
kevman 0:38ceb79fef03 2742 otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely
kevman 0:38ceb79fef03 2743 close the connection.
kevman 0:38ceb79fef03 2744
kevman 0:38ceb79fef03 2745 2007-08-16 Marc Boucher
kevman 0:38ceb79fef03 2746 * sockets.c: lwip_accept(): check netconn_peer() error return.
kevman 0:38ceb79fef03 2747
kevman 0:38ceb79fef03 2748 2007-08-16 Marc Boucher
kevman 0:38ceb79fef03 2749 * mem.c, mem.h: Added mem_calloc().
kevman 0:38ceb79fef03 2750
kevman 0:38ceb79fef03 2751 2007-08-16 Marc Boucher
kevman 0:38ceb79fef03 2752 * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT)
kevman 0:38ceb79fef03 2753 for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG
kevman 0:38ceb79fef03 2754 and starving other message types.
kevman 0:38ceb79fef03 2755 Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API
kevman 0:38ceb79fef03 2756
kevman 0:38ceb79fef03 2757 2007-08-16 Marc Boucher
kevman 0:38ceb79fef03 2758 * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf
kevman 0:38ceb79fef03 2759 type and flgs (later renamed to flags).
kevman 0:38ceb79fef03 2760 Use enum pbuf_flag as pbuf_type. Renumber PBUF_FLAG_*.
kevman 0:38ceb79fef03 2761 Improved lwip_recvfrom(). TCP push now propagated.
kevman 0:38ceb79fef03 2762
kevman 0:38ceb79fef03 2763 2007-08-16 Marc Boucher
kevman 0:38ceb79fef03 2764 * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global
kevman 0:38ceb79fef03 2765 provided by etharp.
kevman 0:38ceb79fef03 2766
kevman 0:38ceb79fef03 2767 2007-08-16 Marc Boucher
kevman 0:38ceb79fef03 2768 * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h,
kevman 0:38ceb79fef03 2769 etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c:
kevman 0:38ceb79fef03 2770 Added PPPoE support and various PPP improvements.
kevman 0:38ceb79fef03 2771
kevman 0:38ceb79fef03 2772 2007-07-25 Simon Goldschmidt
kevman 0:38ceb79fef03 2773 * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial,
kevman 0:38ceb79fef03 2774 making netbuf_copy_partial use this function.
kevman 0:38ceb79fef03 2775
kevman 0:38ceb79fef03 2776 2007-07-25 Simon Goldschmidt
kevman 0:38ceb79fef03 2777 * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with
kevman 0:38ceb79fef03 2778 2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and
kevman 0:38ceb79fef03 2779 other stacks.
kevman 0:38ceb79fef03 2780
kevman 0:38ceb79fef03 2781 2007-07-13 Jared Grubb (integrated by Frédéric Bernon)
kevman 0:38ceb79fef03 2782 * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add
kevman 0:38ceb79fef03 2783 a link callback in the netif struct, and functions to handle it. Be carefull
kevman 0:38ceb79fef03 2784 for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c)
kevman 0:38ceb79fef03 2785 if you want to be sure to be compatible with future changes...
kevman 0:38ceb79fef03 2786
kevman 0:38ceb79fef03 2787 2007-06-30 Frédéric Bernon
kevman 0:38ceb79fef03 2788 * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.
kevman 0:38ceb79fef03 2789
kevman 0:38ceb79fef03 2790 2007-06-21 Simon Goldschmidt
kevman 0:38ceb79fef03 2791 * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both
kevman 0:38ceb79fef03 2792 LWIP_AUTOIP =0 and =1 to remove redundant code.
kevman 0:38ceb79fef03 2793
kevman 0:38ceb79fef03 2794 2007-06-21 Simon Goldschmidt
kevman 0:38ceb79fef03 2795 * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option
kevman 0:38ceb79fef03 2796 MEM_USE_POOLS to use 4 pools with different sized elements instead of a
kevman 0:38ceb79fef03 2797 heap. This both prevents memory fragmentation and gives a higher speed
kevman 0:38ceb79fef03 2798 at the cost of more memory consumption. Turned off by default.
kevman 0:38ceb79fef03 2799
kevman 0:38ceb79fef03 2800 2007-06-21 Simon Goldschmidt
kevman 0:38ceb79fef03 2801 * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of
kevman 0:38ceb79fef03 2802 netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into
kevman 0:38ceb79fef03 2803 int to be able to send a bigger buffer than 64K with one time (mainly
kevman 0:38ceb79fef03 2804 used from lwip_send).
kevman 0:38ceb79fef03 2805
kevman 0:38ceb79fef03 2806 2007-06-21 Simon Goldschmidt
kevman 0:38ceb79fef03 2807 * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write
kevman 0:38ceb79fef03 2808 into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too.
kevman 0:38ceb79fef03 2809
kevman 0:38ceb79fef03 2810 2007-06-21 Simon Goldschmidt
kevman 0:38ceb79fef03 2811 * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in
kevman 0:38ceb79fef03 2812 netconn_write from api_lib.c to api_msg.c to also prevent multiple context-
kevman 0:38ceb79fef03 2813 changes on low memory or empty send-buffer.
kevman 0:38ceb79fef03 2814
kevman 0:38ceb79fef03 2815 2007-06-18 Simon Goldschmidt
kevman 0:38ceb79fef03 2816 * etharp.c, etharp.h: Changed etharp to use a defined hardware address length
kevman 0:38ceb79fef03 2817 of 6 to avoid loading netif->hwaddr_len every time (since this file is only
kevman 0:38ceb79fef03 2818 used for ethernet and struct eth_addr already had a defined length of 6).
kevman 0:38ceb79fef03 2819
kevman 0:38ceb79fef03 2820 2007-06-17 Simon Goldschmidt
kevman 0:38ceb79fef03 2821 * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets
kevman 0:38ceb79fef03 2822 to disable UDP checksum generation on transmit.
kevman 0:38ceb79fef03 2823
kevman 0:38ceb79fef03 2824 2007-06-13 Frédéric Bernon, Simon Goldschmidt
kevman 0:38ceb79fef03 2825 * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid
kevman 0:38ceb79fef03 2826 pointers or parameters, and let the possibility to redefined it in cc.h. Use
kevman 0:38ceb79fef03 2827 this macro to check "conn" parameter in api_msg.c functions.
kevman 0:38ceb79fef03 2828
kevman 0:38ceb79fef03 2829 2007-06-11 Simon Goldschmidt
kevman 0:38ceb79fef03 2830 * sockets.c, sockets.h: Added UDP lite support for sockets
kevman 0:38ceb79fef03 2831
kevman 0:38ceb79fef03 2832 2007-06-10 Simon Goldschmidt
kevman 0:38ceb79fef03 2833 * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled
kevman 0:38ceb79fef03 2834 by default) to switch off UDP-Lite support if not needed (reduces udp.c code
kevman 0:38ceb79fef03 2835 size)
kevman 0:38ceb79fef03 2836
kevman 0:38ceb79fef03 2837 2007-06-09 Dominik Spies (integrated by Frédéric Bernon)
kevman 0:38ceb79fef03 2838 * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h:
kevman 0:38ceb79fef03 2839 AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and
kevman 0:38ceb79fef03 2840 LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt
kevman 0:38ceb79fef03 2841 (see TODO mark in the source code).
kevman 0:38ceb79fef03 2842
kevman 0:38ceb79fef03 2843 2007-06-09 Simon Goldschmidt
kevman 0:38ceb79fef03 2844 * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for
kevman 0:38ceb79fef03 2845 etharp_output() to match netif->output so etharp_output() can be used
kevman 0:38ceb79fef03 2846 directly as netif->output to save one function call.
kevman 0:38ceb79fef03 2847
kevman 0:38ceb79fef03 2848 2007-06-08 Simon Goldschmidt
kevman 0:38ceb79fef03 2849 * netif.h, ethernetif.c, slipif.c, loopif.c: Added define
kevman 0:38ceb79fef03 2850 NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables,
kevman 0:38ceb79fef03 2851 added initialization of those to ethernetif, slipif and loopif.
kevman 0:38ceb79fef03 2852
kevman 0:38ceb79fef03 2853 2007-05-18 Simon Goldschmidt
kevman 0:38ceb79fef03 2854 * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF
kevman 0:38ceb79fef03 2855 (defaulting to off for now) that can be set to 0 to send fragmented
kevman 0:38ceb79fef03 2856 packets by passing PBUF_REFs down the stack.
kevman 0:38ceb79fef03 2857
kevman 0:38ceb79fef03 2858 2007-05-23 Frédéric Bernon
kevman 0:38ceb79fef03 2859 * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP
kevman 0:38ceb79fef03 2860 connections, such present in patch #5959.
kevman 0:38ceb79fef03 2861
kevman 0:38ceb79fef03 2862 2007-05-23 Frédéric Bernon
kevman 0:38ceb79fef03 2863 * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx
kevman 0:38ceb79fef03 2864 code in only one part...
kevman 0:38ceb79fef03 2865
kevman 0:38ceb79fef03 2866 2007-05-18 Simon Goldschmidt
kevman 0:38ceb79fef03 2867 * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp
kevman 0:38ceb79fef03 2868 elements to overflow. This is achieved by adding some bytes before and after
kevman 0:38ceb79fef03 2869 each pool element (increasing their size, of course), filling them with a
kevman 0:38ceb79fef03 2870 prominent value and checking them on freeing the element.
kevman 0:38ceb79fef03 2871 Set it to 2 to also check every element in every pool each time memp_malloc()
kevman 0:38ceb79fef03 2872 or memp_free() is called (slower but more helpful).
kevman 0:38ceb79fef03 2873
kevman 0:38ceb79fef03 2874 2007-05-10 Simon Goldschmidt
kevman 0:38ceb79fef03 2875 * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for
kevman 0:38ceb79fef03 2876 PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce
kevman 0:38ceb79fef03 2877 code size.
kevman 0:38ceb79fef03 2878
kevman 0:38ceb79fef03 2879 2007-05-11 Frédéric Bernon
kevman 0:38ceb79fef03 2880 * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c:
kevman 0:38ceb79fef03 2881 Include a function pointer instead of a table index in the message to reduce
kevman 0:38ceb79fef03 2882 footprint. Disable some part of lwip_send and lwip_sendto if some options are
kevman 0:38ceb79fef03 2883 not set (LWIP_TCP, LWIP_UDP, LWIP_RAW).
kevman 0:38ceb79fef03 2884
kevman 0:38ceb79fef03 2885 2007-05-10 Simon Goldschmidt
kevman 0:38ceb79fef03 2886 * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus
kevman 0:38ceb79fef03 2887 \ extern "C" {' in all header files. Now you can write your application using
kevman 0:38ceb79fef03 2888 the lwIP stack in C++ and simply #include the core files. Note I have left
kevman 0:38ceb79fef03 2889 out the netif/ppp/*h header files for now, since I don't know which files are
kevman 0:38ceb79fef03 2890 included by applications and which are for internal use only.
kevman 0:38ceb79fef03 2891
kevman 0:38ceb79fef03 2892 2007-05-09 Simon Goldschmidt
kevman 0:38ceb79fef03 2893 * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library
kevman 0:38ceb79fef03 2894 memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for
kevman 0:38ceb79fef03 2895 situations where some compilers might inline the copy and save a function
kevman 0:38ceb79fef03 2896 call. Also replaced all calls to memcpy() with calls to (S)MEMCPY().
kevman 0:38ceb79fef03 2897
kevman 0:38ceb79fef03 2898 2007-05-08 Simon Goldschmidt
kevman 0:38ceb79fef03 2899 * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc())
kevman 0:38ceb79fef03 2900 to be overriden in case the C-library malloc implementation is not protected
kevman 0:38ceb79fef03 2901 against concurrent access.
kevman 0:38ceb79fef03 2902
kevman 0:38ceb79fef03 2903 2007-05-04 Simon Goldschmidt (Atte Kojo)
kevman 0:38ceb79fef03 2904 * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending
kevman 0:38ceb79fef03 2905 multiple packets to the same host.
kevman 0:38ceb79fef03 2906
kevman 0:38ceb79fef03 2907 2007-05-04 Frédéric Bernon, Jonathan Larmour
kevman 0:38ceb79fef03 2908 * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible
kevman 0:38ceb79fef03 2909 to corrupt remote addr/port connection state". Reduce problems "not enought memory" with
kevman 0:38ceb79fef03 2910 netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between
kevman 0:38ceb79fef03 2911 sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function.
kevman 0:38ceb79fef03 2912 Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct,
kevman 0:38ceb79fef03 2913 these fields are now renamed "addr" & "port".
kevman 0:38ceb79fef03 2914
kevman 0:38ceb79fef03 2915 2007-04-11 Jonathan Larmour
kevman 0:38ceb79fef03 2916 * sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new
kevman 0:38ceb79fef03 2917 sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return
kevman 0:38ceb79fef03 2918 with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro
kevman 0:38ceb79fef03 2919 by the port in sys_arch.h if desired.
kevman 0:38ceb79fef03 2920
kevman 0:38ceb79fef03 2921 2007-04-06 Frédéric Bernon, Simon Goldschmidt
kevman 0:38ceb79fef03 2922 * opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API
kevman 0:38ceb79fef03 2923 allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp
kevman 0:38ceb79fef03 2924 clients, using new functions from netifapi.h. Disable as default (no port change to do).
kevman 0:38ceb79fef03 2925
kevman 0:38ceb79fef03 2926 2007-04-05 Frédéric Bernon
kevman 0:38ceb79fef03 2927 * sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant.
kevman 0:38ceb79fef03 2928
kevman 0:38ceb79fef03 2929 2007-04-04 Simon Goldschmidt
kevman 0:38ceb79fef03 2930 * arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x)
kevman 0:38ceb79fef03 2931 use this for and architecture-independent form to tell the compiler you intentionally
kevman 0:38ceb79fef03 2932 are not using this variable. Can be overriden in cc.h.
kevman 0:38ceb79fef03 2933
kevman 0:38ceb79fef03 2934 2007-03-28 Frédéric Bernon
kevman 0:38ceb79fef03 2935 * opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to
kevman 0:38ceb79fef03 2936 define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded
kevman 0:38ceb79fef03 2937 string, point on one of your's ethernetif field, or alloc a string you will free yourself).
kevman 0:38ceb79fef03 2938 It will be used by DHCP to register a client hostname, but can also be use when you call
kevman 0:38ceb79fef03 2939 snmp_set_sysname.

kevman 0:38ceb79fef03 2941 2007-03-28 Frédéric Bernon
kevman 0:38ceb79fef03 2942 * netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to
kevman 0:38ceb79fef03 2943 initialize a network interface's flag with. It tell this interface is an ethernet
kevman 0:38ceb79fef03 2944 device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility
kevman 0:38ceb79fef03 2945 Support for IPv4" section 4.6) when interface is "up" with netif_set_up().
kevman 0:38ceb79fef03 2946
kevman 0:38ceb79fef03 2947 2007-03-26 Frédéric Bernon, Jonathan Larmour
kevman 0:38ceb79fef03 2948 * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build
kevman 0:38ceb79fef03 2949 time if you only use PPP or SLIP. The default is enable. Note we don't have to call
kevman 0:38ceb79fef03 2950 etharp_init in your port's initilization sequence if you use tcpip.c, because this call
kevman 0:38ceb79fef03 2951 is done in tcpip_init function.

kevman 0:38ceb79fef03 2953 2007-03-22 Frédéric Bernon
kevman 0:38ceb79fef03 2954 * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the
kevman 0:38ceb79fef03 2955 new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in
kevman 0:38ceb79fef03 2956 your lwipopts.h. More, unused counters are not defined in the stats structs, and not
kevman 0:38ceb79fef03 2957 display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined
kevman 0:38ceb79fef03 2958 but never used. Fix msg_in.c with the correct #if test for a stat display.

kevman 0:38ceb79fef03 2960 2007-03-21 Kieran Mansley
kevman 0:38ceb79fef03 2961 * netif.c, netif.h: Apply patch#4197 with some changes (originator: rireland@hmgsl.com).
kevman 0:38ceb79fef03 2962 Provides callback on netif up/down state change.

kevman 0:38ceb79fef03 2966 ip.c, netif.h, tcpip.c, opt.h:
kevman 0:38ceb79fef03 2967 New configuration option LWIP_IGMP to enable IGMP processing. Based on only one
kevman 0:38ceb79fef03 2968 filter per all network interfaces. Declare a new function in netif to enable to
kevman 0:38ceb79fef03 2969 control the MAC filter (to reduce lwIP traffic processing).

kevman 0:38ceb79fef03 2972 * tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can
kevman 0:38ceb79fef03 2973 be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this
kevman 0:38ceb79fef03 2974 unless you know what you're doing (default are RFC1122 compliant). Note
kevman 0:38ceb79fef03 2975 that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds.

kevman 0:38ceb79fef03 2998 * sockets.h, sockets.c: Move socket initialization to new
kevman 0:38ceb79fef03 2999 lwip_socket_init() function.
kevman 0:38ceb79fef03 3000 NOTE: this changes the API with ports. Ports will have to be
kevman 0:38ceb79fef03 3001 updated to call lwip_socket_init() now.

kevman 0:38ceb79fef03 3009 2008-03-17 Frédéric Bernon, Ed Kerekes
kevman 0:38ceb79fef03 3010 * igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have
kevman 0:38ceb79fef03 3011 some problems to fill the IP header on some targets, use now the
kevman 0:38ceb79fef03 3012 ip.h macros to do it).
kevman 0:38ceb79fef03 3013
kevman 0:38ceb79fef03 3014 2008-03-13 Frédéric Bernon
kevman 0:38ceb79fef03 3015 * sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using
kevman 0:38ceb79fef03 3016 (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a
kevman 0:38ceb79fef03 3017 TCP connection caused a crash. Note that using (lwip_)recvfrom
kevman 0:38ceb79fef03 3018 like this is a bit slow and that using (lwip)getpeername is the
kevman 0:38ceb79fef03 3019 good lwip way to do it (so, using recv is faster on tcp sockets).

kevman 0:38ceb79fef03 3023 recv_raw() does not consume data", and the ping sample (with
kevman 0:38ceb79fef03 3024 LWIP_SOCKET=1, the code did the wrong supposition that lwip_recvfrom
kevman 0:38ceb79fef03 3025 returned the IP payload, without the IP header).

kevman 0:38ceb79fef03 3028 * mem.c, stats.c, mem.h: apply patch #6414 to avoid compiler errors
kevman 0:38ceb79fef03 3029 and/or warnings on some systems where mem_size_t and size_t differ.
kevman 0:38ceb79fef03 3030 * pbuf.c, ppp.c: Fix warnings on some systems with mem_malloc.

kevman 0:38ceb79fef03 3061 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: fix bug #20199 (better handling

kevman 0:38ceb79fef03 3066 data packet was lost): add assert that all segment lists are empty in
kevman 0:38ceb79fef03 3067 tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED

kevman 0:38ceb79fef03 3072 If including <sys/time.h> for system-struct timeval, LWIP_TIMEVAL_PRIVATE now

kevman 0:38ceb79fef03 3076 * api_msg.c, api_lib.c: fix bug #21656 (recvmbox problem in netconn API): always
kevman 0:38ceb79fef03 3077 allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen
kevman 0:38ceb79fef03 3078 netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox.
kevman 0:38ceb79fef03 3079 This is a fix for thread-safety and allocates all items needed for a netconn
kevman 0:38ceb79fef03 3080 when the netconn is created.

kevman 0:38ceb79fef03 3084 netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed
kevman 0:38ceb79fef03 3085 to netif->dhcp->pcb only (if that exists) and not to any other pcb for the same
kevman 0:38ceb79fef03 3086 port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address)

kevman 0:38ceb79fef03 3088 2007-11-27 Simon Goldschmidt
kevman 0:38ceb79fef03 3089 * ip.c: fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by
kevman 0:38ceb79fef03 3090 letting ip_route only use netifs that are up.
kevman 0:38ceb79fef03 3091
kevman 0:38ceb79fef03 3092 2007-11-27 Simon Goldschmidt
kevman 0:38ceb79fef03 3093 * err.h, api_lib.c, api_msg.c, sockets.c: Changed error handling: ERR_MEM, ERR_BUF
kevman 0:38ceb79fef03 3094 and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and
kevman 0:38ceb79fef03 3095 sockets block most operations once they have seen a fatal error.

kevman 0:38ceb79fef03 3097 2007-11-27 Simon Goldschmidt
kevman 0:38ceb79fef03 3098 * udp.h, udp.c, dhcp.c: Implemented new function udp_sendto_if which takes the
kevman 0:38ceb79fef03 3099 netif to send as an argument (to be able to send on netifs that are down).
kevman 0:38ceb79fef03 3100
kevman 0:38ceb79fef03 3101 2007-11-26 Simon Goldschmidt
kevman 0:38ceb79fef03 3102 * tcp_in.c: Fixed bug #21582: pcb->acked accounting can be wrong when ACKs
kevman 0:38ceb79fef03 3103 arrive out-of-order
kevman 0:38ceb79fef03 3104
kevman 0:38ceb79fef03 3105 2007-11-21 Simon Goldschmidt
kevman 0:38ceb79fef03 3106 * tcp.h, tcp_out.c, api_msg.c: Fixed bug #20287: tcp_output_nagle sends too early
kevman 0:38ceb79fef03 3107 Fixed the nagle algorithm; nagle now also works for all raw API applications
kevman 0:38ceb79fef03 3108 and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY'
kevman 0:38ceb79fef03 3109
kevman 0:38ceb79fef03 3110 2007-11-12 Frédéric Bernon
kevman 0:38ceb79fef03 3111 * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most
kevman 0:38ceb79fef03 3112 of the netconn_peer and netconn_addr processing is done inside tcpip_thread
kevman 0:38ceb79fef03 3113 context in do_getaddr.
kevman 0:38ceb79fef03 3114
kevman 0:38ceb79fef03 3115 2007-11-10 Simon Goldschmidt
kevman 0:38ceb79fef03 3116 * etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can
kevman 0:38ceb79fef03 3117 happen any time). Now the packet simply isn't enqueued when out of memory.
kevman 0:38ceb79fef03 3118
kevman 0:38ceb79fef03 3119 2007-11-01 Simon Goldschmidt
kevman 0:38ceb79fef03 3120 * tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or
kevman 0:38ceb79fef03 3121 TCP_MSS if that is smaller) as long as no MSS option is received from the
kevman 0:38ceb79fef03 3122 remote host.
kevman 0:38ceb79fef03 3123
kevman 0:38ceb79fef03 3124 2007-11-01 Simon Goldschmidt
kevman 0:38ceb79fef03 3125 * tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN)
kevman 0:38ceb79fef03 3126 is now based on TCP_MSS instead of pcb->mss (on passive open now effectively
kevman 0:38ceb79fef03 3127 sending our configured TCP_MSS instead of the one received).
kevman 0:38ceb79fef03 3128
kevman 0:38ceb79fef03 3129 2007-11-01 Simon Goldschmidt
kevman 0:38ceb79fef03 3130 * tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was
kevman 0:38ceb79fef03 3131 calculated based on the configured TCP_MSS, not on the MSS option received
kevman 0:38ceb79fef03 3132 with SYN+ACK.
kevman 0:38ceb79fef03 3133
kevman 0:38ceb79fef03 3134 2007-10-09 Simon Goldschmidt
kevman 0:38ceb79fef03 3135 * udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too
kevman 0:38ceb79fef03 3136 short and also was generated wrong if checksum coverage != tot_len;
kevman 0:38ceb79fef03 3137 receive: checksum was calculated wrong if checksum coverage != tot_len
kevman 0:38ceb79fef03 3138
kevman 0:38ceb79fef03 3139 2007-10-08 Simon Goldschmidt
kevman 0:38ceb79fef03 3140 * mem.c: lfree was not updated in mem_realloc!

kevman 0:38ceb79fef03 3142 2007-10-07 Frédéric Bernon
kevman 0:38ceb79fef03 3143 * sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential
kevman 0:38ceb79fef03 3144 crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT:
kevman 0:38ceb79fef03 3145 this change cause an API breakage for netconn_addr, since a parameter
kevman 0:38ceb79fef03 3146 type change. Any compiler should cause an error without any changes in
kevman 0:38ceb79fef03 3147 yours netconn_peer calls (so, it can't be a "silent change"). It also
kevman 0:38ceb79fef03 3148 reduce a little bit the footprint for socket layer (lwip_getpeername &
kevman 0:38ceb79fef03 3149 lwip_getsockname use now a common lwip_getaddrname function since
kevman 0:38ceb79fef03 3150 netconn_peer & netconn_addr have the same parameters).

kevman 0:38ceb79fef03 3152 2007-09-20 Simon Goldschmidt
kevman 0:38ceb79fef03 3153 * tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state)
kevman 0:38ceb79fef03 3154 by checking tcp_tw_pcbs also
kevman 0:38ceb79fef03 3155
kevman 0:38ceb79fef03 3156 2007-09-19 Simon Goldschmidt
kevman 0:38ceb79fef03 3157 * icmp.c: Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies)
kevman 0:38ceb79fef03 3158
kevman 0:38ceb79fef03 3159 2007-09-15 Mike Kleshov
kevman 0:38ceb79fef03 3160 * mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used)
kevman 0:38ceb79fef03 3161
kevman 0:38ceb79fef03 3162 2007-09-06 Frédéric Bernon
kevman 0:38ceb79fef03 3163 * several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove
kevman 0:38ceb79fef03 3164 it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which
kevman 0:38ceb79fef03 3165 already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h"
kevman 0:38ceb79fef03 3166 if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h.
kevman 0:38ceb79fef03 3167
kevman 0:38ceb79fef03 3168 2007-08-30 Frédéric Bernon
kevman 0:38ceb79fef03 3169 * igmp.h, igmp.c: Some changes to remove some redundant code, add some traces,
kevman 0:38ceb79fef03 3170 and fix some coding style.
kevman 0:38ceb79fef03 3171
kevman 0:38ceb79fef03 3172 2007-08-28 Frédéric Bernon
kevman 0:38ceb79fef03 3173 * tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any
kevman 0:38ceb79fef03 3174 kind of packets. These packets are considered like Ethernet packets (payload
kevman 0:38ceb79fef03 3175 pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets
kevman 0:38ceb79fef03 3176 are considered like IP packets (payload pointing to iphdr).
kevman 0:38ceb79fef03 3177
kevman 0:38ceb79fef03 3178 2007-08-27 Frédéric Bernon
kevman 0:38ceb79fef03 3179 * api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error
kevman 0:38ceb79fef03 3180 problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state
kevman 0:38ceb79fef03 3181 and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT).
kevman 0:38ceb79fef03 3182
kevman 0:38ceb79fef03 3183 2007-08-24 Kieran Mansley
kevman 0:38ceb79fef03 3184 * inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy
kevman 0:38ceb79fef03 3185 compiler (Paradigm C++)
kevman 0:38ceb79fef03 3186
kevman 0:38ceb79fef03 3187 2007-08-09 Frédéric Bernon, Bill Florac
kevman 0:38ceb79fef03 3188 * stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement.
kevman 0:38ceb79fef03 3189 Introduce IGMP_STATS to centralize statistics management.
kevman 0:38ceb79fef03 3190
kevman 0:38ceb79fef03 3191 2007-08-09 Frédéric Bernon, Bill Florac
kevman 0:38ceb79fef03 3192 * udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast
kevman 0:38ceb79fef03 3193 packet on a udp pcb binded on an netif's IP address, and not on "any".
kevman 0:38ceb79fef03 3194
kevman 0:38ceb79fef03 3195 2007-08-09 Frédéric Bernon, Bill Florac
kevman 0:38ceb79fef03 3196 * igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement.
kevman 0:38ceb79fef03 3197 This is mainly on using lookup/lookfor, and some coding styles...
kevman 0:38ceb79fef03 3198
kevman 0:38ceb79fef03 3199 2007-07-26 Frédéric Bernon (and "thedoctor")
kevman 0:38ceb79fef03 3200 * igmp.c: Fix bug #20595 to accept IGMPv3 "Query" messages.
kevman 0:38ceb79fef03 3201
kevman 0:38ceb79fef03 3202 2007-07-25 Simon Goldschmidt
kevman 0:38ceb79fef03 3203 * api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if
kevman 0:38ceb79fef03 3204 tcp_output fails in tcp_close, the code in do_close_internal gets simpler
kevman 0:38ceb79fef03 3205 (tcp_output is called again later from tcp timers).
kevman 0:38ceb79fef03 3206
kevman 0:38ceb79fef03 3207 2007-07-25 Simon Goldschmidt
kevman 0:38ceb79fef03 3208 * ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old
kevman 0:38ceb79fef03 3209 copy_from_pbuf, which illegally modified the given pbuf.
kevman 0:38ceb79fef03 3210
kevman 0:38ceb79fef03 3211 2007-07-25 Simon Goldschmidt
kevman 0:38ceb79fef03 3212 * tcp_out.c: tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs:
kevman 0:38ceb79fef03 3213 changed snd_queuelen++ to snd_queuelen += pbuf_clen(p).
kevman 0:38ceb79fef03 3214
kevman 0:38ceb79fef03 3215 2007-07-24 Simon Goldschmidt
kevman 0:38ceb79fef03 3216 * api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the
kevman 0:38ceb79fef03 3217 correct state (must be CLOSED).
kevman 0:38ceb79fef03 3218
kevman 0:38ceb79fef03 3219 2007-07-13 Thomas Taranowski (commited by Jared Grubb)
kevman 0:38ceb79fef03 3220 * memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed
kevman 0:38ceb79fef03 3221 allocation. It now returns NULL.
kevman 0:38ceb79fef03 3222
kevman 0:38ceb79fef03 3223 2007-07-13 Frédéric Bernon
kevman 0:38ceb79fef03 3224 * api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in
kevman 0:38ceb79fef03 3225 all error cases.
kevman 0:38ceb79fef03 3226
kevman 0:38ceb79fef03 3227 2007-07-13 Frédéric Bernon
kevman 0:38ceb79fef03 3228 * api_msg.c: Fix bug #20315: possible memory leak problem if tcp_listen failed,
kevman 0:38ceb79fef03 3229 because current code doesn't follow rawapi.txt documentation.
kevman 0:38ceb79fef03 3230
kevman 0:38ceb79fef03 3231 2007-07-13 Kieran Mansley
kevman 0:38ceb79fef03 3232 * src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in
kevman 0:38ceb79fef03 3233 out of sequence processing of received packets
kevman 0:38ceb79fef03 3234
kevman 0:38ceb79fef03 3235 2007-07-03 Simon Goldschmidt
kevman 0:38ceb79fef03 3236 * nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an
kevman 0:38ceb79fef03 3237 assumption is made that this pbuf is in one piece (i.e. not chained). These
kevman 0:38ceb79fef03 3238 assumptions clash with the possibility of converting to fully pool-based
kevman 0:38ceb79fef03 3239 pbuf implementations, where PBUF_RAM pbufs might be chained.
kevman 0:38ceb79fef03 3240
kevman 0:38ceb79fef03 3241 2007-07-03 Simon Goldschmidt
kevman 0:38ceb79fef03 3242 * api.h, api_lib.c, api_msg.c: Final fix for bug #20021 and some other problems
kevman 0:38ceb79fef03 3243 when closing tcp netconns: removed conn->sem, less context switches when
kevman 0:38ceb79fef03 3244 closing, both netconn_close and netconn_delete should safely close tcp
kevman 0:38ceb79fef03 3245 connections.
kevman 0:38ceb79fef03 3246
kevman 0:38ceb79fef03 3247 2007-07-02 Simon Goldschmidt
kevman 0:38ceb79fef03 3248 * ipv4/ip.h, ipv6/ip.h, opt.h, netif.h, etharp.h, ipv4/ip.c, netif.c, raw.c,
kevman 0:38ceb79fef03 3249 tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off)
kevman 0:38ceb79fef03 3250 to cache ARP table indices with each pcb instead of single-entry cache for
kevman 0:38ceb79fef03 3251 the complete stack.
kevman 0:38ceb79fef03 3252
kevman 0:38ceb79fef03 3253 2007-07-02 Simon Goldschmidt
kevman 0:38ceb79fef03 3254 * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent
kevman 0:38ceb79fef03 3255 warnings when assigning to smaller types.
kevman 0:38ceb79fef03 3256
kevman 0:38ceb79fef03 3257 2007-06-28 Simon Goldschmidt
kevman 0:38ceb79fef03 3258 * tcp_out.c: Added check to prevent tcp_pcb->snd_queuelen from overflowing.
kevman 0:38ceb79fef03 3259
kevman 0:38ceb79fef03 3260 2007-06-28 Simon Goldschmidt
kevman 0:38ceb79fef03 3261 * tcp.h: Fixed bug #20287: Fixed nagle algorithm (sending was done too early if
kevman 0:38ceb79fef03 3262 a segment contained chained pbufs)
kevman 0:38ceb79fef03 3263
kevman 0:38ceb79fef03 3264 2007-06-28 Frédéric Bernon
kevman 0:38ceb79fef03 3265 * autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute
kevman 0:38ceb79fef03 3266 a "pseudo-random" value based on netif's MAC and some autoip fields. It's always
kevman 0:38ceb79fef03 3267 possible to define this macro in your own lwipopts.h to always use C library's
kevman 0:38ceb79fef03 3268 rand(). Note that autoip_create_rand_addr doesn't use this macro.
kevman 0:38ceb79fef03 3269
kevman 0:38ceb79fef03 3270 2007-06-28 Frédéric Bernon
kevman 0:38ceb79fef03 3271 * netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option
kevman 0:38ceb79fef03 3272 LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications
kevman 0:38ceb79fef03 3273 in api_lib/api_msg (use pointers and not type with table, etc...)
kevman 0:38ceb79fef03 3274
kevman 0:38ceb79fef03 3275 2007-06-26 Simon Goldschmidt
kevman 0:38ceb79fef03 3276 * udp.h: Fixed bug #20259: struct udp_hdr was lacking the packin defines.
kevman 0:38ceb79fef03 3277
kevman 0:38ceb79fef03 3278 2007-06-25 Simon Goldschmidt
kevman 0:38ceb79fef03 3279 * udp.c: Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload
kevman 0:38ceb79fef03 3280 for udp packets with no matching pcb.
kevman 0:38ceb79fef03 3281
kevman 0:38ceb79fef03 3282 2007-06-25 Simon Goldschmidt
kevman 0:38ceb79fef03 3283 * udp.c: Fixed bug #20220: UDP PCB search in udp_input(): a non-local match
kevman 0:38ceb79fef03 3284 could get udp input packets if the remote side matched.
kevman 0:38ceb79fef03 3285
kevman 0:38ceb79fef03 3286 2007-06-13 Simon Goldschmidt
kevman 0:38ceb79fef03 3287 * netif.c: Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get
kevman 0:38ceb79fef03 3288 changed in netif_set_ipaddr if previous netif->ip_addr.addr was 0.
kevman 0:38ceb79fef03 3289
kevman 0:38ceb79fef03 3290 2007-06-13 Simon Goldschmidt
kevman 0:38ceb79fef03 3291 * api_msg.c: pcb_new sets conn->err if protocol is not implemented
kevman 0:38ceb79fef03 3292 -> netconn_new_..() does not allocate a new connection for unsupported
kevman 0:38ceb79fef03 3293 protocols.
kevman 0:38ceb79fef03 3294
kevman 0:38ceb79fef03 3295 2007-06-13 Frédéric Bernon, Simon Goldschmidt
kevman 0:38ceb79fef03 3296 * api_lib.c: change return expression in netconn_addr and netconn_peer, because
kevman 0:38ceb79fef03 3297 conn->err was reset to ERR_OK without any reasons (and error was lost)...
kevman 0:38ceb79fef03 3298
kevman 0:38ceb79fef03 3299 2007-06-13 Frédéric Bernon, Matthias Weisser
kevman 0:38ceb79fef03 3300 * opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename
kevman 0:38ceb79fef03 3301 MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid
kevman 0:38ceb79fef03 3302 some macro names collision with some OS macros.
kevman 0:38ceb79fef03 3303
kevman 0:38ceb79fef03 3304 2007-06-11 Simon Goldschmidt
kevman 0:38ceb79fef03 3305 * udp.c: UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0,
kevman 0:38ceb79fef03 3306 create checksum over the complete packet. On RX, if it's < 8 (and not 0),
kevman 0:38ceb79fef03 3307 discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both
kevman 0:38ceb79fef03 3308 UDP & UDP Lite.
kevman 0:38ceb79fef03 3309
kevman 0:38ceb79fef03 3310 2007-06-11 Srinivas Gollakota & Oleg Tyshev
kevman 0:38ceb79fef03 3311 * tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP flags"
kevman 0:38ceb79fef03 3312 where TCP flags wasn't initialized in tcp_keepalive.
kevman 0:38ceb79fef03 3313
kevman 0:38ceb79fef03 3314 2007-06-03 Simon Goldschmidt
kevman 0:38ceb79fef03 3315 * udp.c: udp_input(): Input pbuf was not freed if pcb had no recv function
kevman 0:38ceb79fef03 3316 registered, p->payload was modified without modifying p->len if sending
kevman 0:38ceb79fef03 3317 icmp_dest_unreach() (had no negative effect but was definitively wrong).
kevman 0:38ceb79fef03 3318
kevman 0:38ceb79fef03 3319 2007-06-03 Simon Goldschmidt
kevman 0:38ceb79fef03 3320 * icmp.c: Corrected bug #19937: For responding to an icmp echo request, icmp
kevman 0:38ceb79fef03 3321 re-used the input pbuf even if that didn't have enough space to include the
kevman 0:38ceb79fef03 3322 link headers. Now the space is tested and a new pbuf is allocated for the
kevman 0:38ceb79fef03 3323 echo response packet if the echo request pbuf isn't big enough.
kevman 0:38ceb79fef03 3324
kevman 0:38ceb79fef03 3325 2007-06-01 Simon Goldschmidt
kevman 0:38ceb79fef03 3326 * sockets.c: Checked in patch #5914: Moved sockopt processing into tcpip_thread.
kevman 0:38ceb79fef03 3327
kevman 0:38ceb79fef03 3328 2007-05-23 Frédéric Bernon
kevman 0:38ceb79fef03 3329 * api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only
kevman 0:38ceb79fef03 3330 allocated by do_listen if success) and netconn_accept errors handling. In
kevman 0:38ceb79fef03 3331 most of api_lib functions, we replace some errors checkings like "if (conn==NULL)"
kevman 0:38ceb79fef03 3332 by ASSERT, except for netconn_delete.
kevman 0:38ceb79fef03 3333
kevman 0:38ceb79fef03 3334 2007-05-23 Frédéric Bernon
kevman 0:38ceb79fef03 3335 * api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return
kevman 0:38ceb79fef03 3336 an error code if it's impossible to fetch a pbuf on a TCP connection (and not
kevman 0:38ceb79fef03 3337 directly close the recvmbox).
kevman 0:38ceb79fef03 3338
kevman 0:38ceb79fef03 3339 2007-05-22 Simon Goldschmidt
kevman 0:38ceb79fef03 3340 * tcp.c: Fixed bug #1895 (tcp_bind not correct) by introducing a list of
kevman 0:38ceb79fef03 3341 bound but unconnected (and non-listening) tcp_pcbs.
kevman 0:38ceb79fef03 3342
kevman 0:38ceb79fef03 3343 2007-05-22 Frédéric Bernon
kevman 0:38ceb79fef03 3344 * sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only
kevman 0:38ceb79fef03 3345 used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of
kevman 0:38ceb79fef03 3346 sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features
kevman 0:38ceb79fef03 3347 like "sys_timeout" in their application threads.
kevman 0:38ceb79fef03 3348
kevman 0:38ceb79fef03 3349 2007-05-22 Frédéric Bernon
kevman 0:38ceb79fef03 3350 * api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see
kevman 0:38ceb79fef03 3351 which parameters are used by which do_xxx function, and to avoid "misusing"
kevman 0:38ceb79fef03 3352 parameters (patch #5938).
kevman 0:38ceb79fef03 3353
kevman 0:38ceb79fef03 3354 2007-05-22 Simon Goldschmidt
kevman 0:38ceb79fef03 3355 * api_lib.c, api_msg.c, raw.c, api.h, api_msg.h, raw.h: Included patch #5938:
kevman 0:38ceb79fef03 3356 changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto
kevman 0:38ceb79fef03 3357 is only 8 bits wide. This affects the api, as there, the protocol was
kevman 0:38ceb79fef03 3358 u16_t, too.
kevman 0:38ceb79fef03 3359
kevman 0:38ceb79fef03 3360 2007-05-18 Simon Goldschmidt
kevman 0:38ceb79fef03 3361 * memp.c: addition to patch #5913: smaller pointer was returned but
kevman 0:38ceb79fef03 3362 memp_memory was the same size -> did not save memory.
kevman 0:38ceb79fef03 3363
kevman 0:38ceb79fef03 3364 2007-05-16 Simon Goldschmidt
kevman 0:38ceb79fef03 3365 * loopif.c, slipif.c: Fix bug #19729: free pbuf if netif->input() returns
kevman 0:38ceb79fef03 3366 != ERR_OK.
kevman 0:38ceb79fef03 3367
kevman 0:38ceb79fef03 3368 2007-05-16 Simon Goldschmidt
kevman 0:38ceb79fef03 3369 * api_msg.c, udp.c: If a udp_pcb has a local_ip set, check if it is the same
kevman 0:38ceb79fef03 3370 as the one of the netif used for sending to prevent sending from old
kevman 0:38ceb79fef03 3371 addresses after a netif address gets changed (partly fixes bug #3168).
kevman 0:38ceb79fef03 3372
kevman 0:38ceb79fef03 3373 2007-05-16 Frédéric Bernon
kevman 0:38ceb79fef03 3374 * tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work
kevman 0:38ceb79fef03 3375 with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in
kevman 0:38ceb79fef03 3376 tcpip_init) because we have to be sure that network interfaces are already
kevman 0:38ceb79fef03 3377 added (mac filter is updated only in igmp_init for the moment).
kevman 0:38ceb79fef03 3378
kevman 0:38ceb79fef03 3379 2007-05-16 Simon Goldschmidt
kevman 0:38ceb79fef03 3380 * mem.c, memp.c: Removed semaphores from memp, changed sys_sem_wait calls
kevman 0:38ceb79fef03 3381 into sys_arch_sem_wait calls to prevent timers from running while waiting
kevman 0:38ceb79fef03 3382 for the heap. This fixes bug #19167.
kevman 0:38ceb79fef03 3383
kevman 0:38ceb79fef03 3384 2007-05-13 Simon Goldschmidt
kevman 0:38ceb79fef03 3385 * tcp.h, sockets.h, sockets.c: Fixed bug from patch #5865 by moving the defines
kevman 0:38ceb79fef03 3386 for socket options (lwip_set/-getsockopt) used with level IPPROTO_TCP from
kevman 0:38ceb79fef03 3387 tcp.h to sockets.h.

kevman 0:38ceb79fef03 3389 2007-05-07 Simon Goldschmidt
kevman 0:38ceb79fef03 3390 * mem.c: Another attempt to fix bug #17922.
kevman 0:38ceb79fef03 3391
kevman 0:38ceb79fef03 3392 2007-05-04 Simon Goldschmidt
kevman 0:38ceb79fef03 3393 * pbuf.c, pbuf.h, etharp.c: Further update to ARP queueing: Changed pbuf_copy()
kevman 0:38ceb79fef03 3394 implementation so that it can be reused (don't allocate the target
kevman 0:38ceb79fef03 3395 pbuf inside pbuf_copy()).
kevman 0:38ceb79fef03 3396
kevman 0:38ceb79fef03 3397 2007-05-04 Simon Goldschmidt
kevman 0:38ceb79fef03 3398 * memp.c: checked in patch #5913: in memp_malloc() we can return memp as mem
kevman 0:38ceb79fef03 3399 to save a little RAM (next pointer of memp is not used while not in pool).
kevman 0:38ceb79fef03 3400
kevman 0:38ceb79fef03 3401 2007-05-03 "maq"
kevman 0:38ceb79fef03 3402 * sockets.c: Fix ioctl FIONREAD when some data remains from last recv.
kevman 0:38ceb79fef03 3403 (patch #3574).

kevman 0:38ceb79fef03 3406 * loopif.c, loopif.h, opt.h, src/netif/FILES: fix bug #2595: "loopif results
kevman 0:38ceb79fef03 3407 in NULL reference for incoming TCP packets". Loopif has to be configured
kevman 0:38ceb79fef03 3408 (using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input()
kevman 0:38ceb79fef03 3409 (multithreading environments, e.g. netif->input() = tcpip_input()) or
kevman 0:38ceb79fef03 3410 putting packets on a list that is fed to the stack by calling loopif_poll()
kevman 0:38ceb79fef03 3411 (single-thread / NO_SYS / polling environment where e.g.
kevman 0:38ceb79fef03 3412 netif->input() = ip_input).
kevman 0:38ceb79fef03 3413
kevman 0:38ceb79fef03 3414 2007-04-17 Jonathan Larmour
kevman 0:38ceb79fef03 3415 * pbuf.c: Use s32_t in pbuf_realloc(), as an s16_t can't reliably hold
kevman 0:38ceb79fef03 3416 the difference between two u16_t's.
kevman 0:38ceb79fef03 3417 * sockets.h: FD_SETSIZE needs to match number of sockets, which is
kevman 0:38ceb79fef03 3418 MEMP_NUM_NETCONN in sockets.c right now.
kevman 0:38ceb79fef03 3419
kevman 0:38ceb79fef03 3420 2007-04-12 Jonathan Larmour
kevman 0:38ceb79fef03 3421 * icmp.c: Reset IP header TTL in ICMP ECHO responses (bug #19580).
kevman 0:38ceb79fef03 3422
kevman 0:38ceb79fef03 3423 2007-04-12 Kieran Mansley
kevman 0:38ceb79fef03 3424 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Modify way the retransmission
kevman 0:38ceb79fef03 3425 timer is reset to fix bug#19434, with help from Oleg Tyshev.
kevman 0:38ceb79fef03 3426
kevman 0:38ceb79fef03 3427 2007-04-11 Simon Goldschmidt
kevman 0:38ceb79fef03 3428 * etharp.c, pbuf.c, pbuf.h: 3rd fix for bug #11400 (arp-queuing): More pbufs than
kevman 0:38ceb79fef03 3429 previously thought need to be copied (everything but PBUF_ROM!). Cleaned up
kevman 0:38ceb79fef03 3430 pbuf.c: removed functions no needed any more (by etharp).
kevman 0:38ceb79fef03 3431
kevman 0:38ceb79fef03 3432 2007-04-11 Kieran Mansley
kevman 0:38ceb79fef03 3433 * inet.c, ip_addr.h, sockets.h, sys.h, tcp.h: Apply patch #5745: Fix
kevman 0:38ceb79fef03 3434 "Constant is long" warnings with 16bit compilers. Contributed by

kevman 0:38ceb79fef03 3437 2007-04-05 Frédéric Bernon, Jonathan Larmour
kevman 0:38ceb79fef03 3438 * api_msg.c: Fix bug #16830: "err_tcp() posts to connection mailbox when no pend on
kevman 0:38ceb79fef03 3439 the mailbox is active". Now, the post is only done during a connect, and do_send,
kevman 0:38ceb79fef03 3440 do_write and do_join_leave_group don't do anything if a previous error was signaled.
kevman 0:38ceb79fef03 3441
kevman 0:38ceb79fef03 3442 2007-04-03 Frédéric Bernon
kevman 0:38ceb79fef03 3443 * ip.c: Don't set the IP_DF ("Don't fragment") flag in the IP header in IP output
kevman 0:38ceb79fef03 3444 packets. See patch #5834.
kevman 0:38ceb79fef03 3445
kevman 0:38ceb79fef03 3446 2007-03-30 Frédéric Bernon
kevman 0:38ceb79fef03 3447 * api_msg.c: add a "pcb_new" helper function to avoid redundant code, and to add
kevman 0:38ceb79fef03 3448 missing pcb allocations checking (in do_bind, and for each raw_new). Fix style.
kevman 0:38ceb79fef03 3449
kevman 0:38ceb79fef03 3450 2007-03-30 Frédéric Bernon
kevman 0:38ceb79fef03 3451 * most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with
kevman 0:38ceb79fef03 3452 others environment defines (these were too "generic").
kevman 0:38ceb79fef03 3453
kevman 0:38ceb79fef03 3454 2007-03-28 Frédéric Bernon
kevman 0:38ceb79fef03 3455 * api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal pbuf_alloc call
kevman 0:38ceb79fef03 3456 result and can cause a crash. lwip_send now check netbuf_ref result.
kevman 0:38ceb79fef03 3457
kevman 0:38ceb79fef03 3458 2007-03-28 Simon Goldschmidt
kevman 0:38ceb79fef03 3459 * sockets.c Remove "#include <errno.h>" from sockets.c to avoid multiple
kevman 0:38ceb79fef03 3460 definition of macros (in errno.h and lwip/arch.h) if LWIP_PROVIDE_ERRNO is
kevman 0:38ceb79fef03 3461 defined. This is the way it should have been already (looking at
kevman 0:38ceb79fef03 3462 doc/sys_arch.txt)
kevman 0:38ceb79fef03 3463
kevman 0:38ceb79fef03 3464 2007-03-28 Kieran Mansley
kevman 0:38ceb79fef03 3465 * opt.h Change default PBUF_POOL_BUFSIZE (again) to accomodate default MSS +
kevman 0:38ceb79fef03 3466 IP and TCP headers *and* physical link headers
kevman 0:38ceb79fef03 3467
kevman 0:38ceb79fef03 3468 2007-03-26 Frédéric Bernon (based on patch from Dmitry Potapov)
kevman 0:38ceb79fef03 3469 * api_lib.c: patch for netconn_write(), fixes a possible race condition which cause
kevman 0:38ceb79fef03 3470 to send some garbage. It is not a definitive solution, but the patch does solve
kevman 0:38ceb79fef03 3471 the problem for most cases.
kevman 0:38ceb79fef03 3472
kevman 0:38ceb79fef03 3473 2007-03-22 Frédéric Bernon
kevman 0:38ceb79fef03 3474 * api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used).
kevman 0:38ceb79fef03 3475
kevman 0:38ceb79fef03 3476 2007-03-22 Frédéric Bernon
kevman 0:38ceb79fef03 3477 * api_lib.c: somes resources couldn't be freed if there was errors during
kevman 0:38ceb79fef03 3478 netconn_new_with_proto_and_callback.
kevman 0:38ceb79fef03 3479
kevman 0:38ceb79fef03 3480 2007-03-22 Frédéric Bernon
kevman 0:38ceb79fef03 3481 * ethernetif.c: update netif->input calls to check return value. In older ports,
kevman 0:38ceb79fef03 3482 it's a good idea to upgrade them, even if before, there could be another problem
kevman 0:38ceb79fef03 3483 (access to an uninitialized mailbox).
kevman 0:38ceb79fef03 3484
kevman 0:38ceb79fef03 3485 2007-03-21 Simon Goldschmidt
kevman 0:38ceb79fef03 3486 * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed
kevman 0:38ceb79fef03 3487 by casting to unsigned).
kevman 0:38ceb79fef03 3488
kevman 0:38ceb79fef03 3489 2007-03-21 Frédéric Bernon
kevman 0:38ceb79fef03 3490 * api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from
kevman 0:38ceb79fef03 3491 api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a
kevman 0:38ceb79fef03 3492 dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call.
kevman 0:38ceb79fef03 3493 Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a
kevman 0:38ceb79fef03 3494 faster and more reliable communication between api_lib and tcpip.
kevman 0:38ceb79fef03 3495
kevman 0:38ceb79fef03 3496 2007-03-21 Frédéric Bernon
kevman 0:38ceb79fef03 3497 * opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0.
kevman 0:38ceb79fef03 3498
kevman 0:38ceb79fef03 3499 2007-03-21 Frédéric Bernon
kevman 0:38ceb79fef03 3500 * api_msg.c, igmp.c, igmp.h: Fix C++ style comments
kevman 0:38ceb79fef03 3501
kevman 0:38ceb79fef03 3502 2007-03-21 Kieran Mansley
kevman 0:38ceb79fef03 3503 * opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS +
kevman 0:38ceb79fef03 3504 IP and TCP headers
kevman 0:38ceb79fef03 3505
kevman 0:38ceb79fef03 3506 2007-03-21 Kieran Mansley
kevman 0:38ceb79fef03 3507 * Fix all uses of pbuf_header to check the return value. In some
kevman 0:38ceb79fef03 3508 cases just assert if it fails as I'm not sure how to fix them, but
kevman 0:38ceb79fef03 3509 this is no worse than before when they would carry on regardless
kevman 0:38ceb79fef03 3510 of the failure.
kevman 0:38ceb79fef03 3511
kevman 0:38ceb79fef03 3512 2007-03-21 Kieran Mansley
kevman 0:38ceb79fef03 3513 * sockets.c, igmp.c, igmp.h, memp.h: Fix C++ style comments and
kevman 0:38ceb79fef03 3514 comment out missing header include in icmp.c
kevman 0:38ceb79fef03 3515
kevman 0:38ceb79fef03 3516 2007-03-20 Frédéric Bernon
kevman 0:38ceb79fef03 3517 * memp.h, stats.c: Fix stats_display function where memp_names table wasn't
kevman 0:38ceb79fef03 3518 synchronized with memp.h.
kevman 0:38ceb79fef03 3519
kevman 0:38ceb79fef03 3520 2007-03-20 Frédéric Bernon
kevman 0:38ceb79fef03 3521 * tcpip.c: Initialize tcpip's mbox, and verify if initialized in tcpip_input,
kevman 0:38ceb79fef03 3522 tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init problem with
kevman 0:38ceb79fef03 3523 network interfaces. Also fix a compiler warning.
kevman 0:38ceb79fef03 3524
kevman 0:38ceb79fef03 3525 2007-03-20 Kieran Mansley
kevman 0:38ceb79fef03 3526 * udp.c: Only try and use pbuf_header() to make space for headers if
kevman 0:38ceb79fef03 3527 not a ROM or REF pbuf.
kevman 0:38ceb79fef03 3528
kevman 0:38ceb79fef03 3529 2007-03-19 Frédéric Bernon
kevman 0:38ceb79fef03 3530 * api_msg.h, api_msg.c, tcpip.h, tcpip.c: Add return types to tcpip_apimsg()
kevman 0:38ceb79fef03 3531 and api_msg_post().
kevman 0:38ceb79fef03 3532
kevman 0:38ceb79fef03 3533 2007-03-19 Frédéric Bernon
kevman 0:38ceb79fef03 3534 * Remove unimplemented "memp_realloc" function from memp.h.
kevman 0:38ceb79fef03 3535
kevman 0:38ceb79fef03 3536 2007-03-11 Simon Goldschmidt
kevman 0:38ceb79fef03 3537 * pbuf.c: checked in patch #5796: pbuf_alloc: len field claculation caused
kevman 0:38ceb79fef03 3538 memory corruption.
kevman 0:38ceb79fef03 3539
kevman 0:38ceb79fef03 3540 2007-03-11 Simon Goldschmidt (based on patch from Dmitry Potapov)
kevman 0:38ceb79fef03 3541 * api_lib.c, sockets.c, api.h, api_msg.h, sockets.h: Fixed bug #19251
kevman 0:38ceb79fef03 3542 (missing `const' qualifier in socket functions), to get more compatible to
kevman 0:38ceb79fef03 3543 standard POSIX sockets.
kevman 0:38ceb79fef03 3544
kevman 0:38ceb79fef03 3545 2007-03-11 Frédéric Bernon (based on patch from Dmitry Potapov)
kevman 0:38ceb79fef03 3546 * sockets.c: Add asserts inside bind, connect and sendto to check input
kevman 0:38ceb79fef03 3547 parameters. Remove excessive set_errno() calls after get_socket(), because
kevman 0:38ceb79fef03 3548 errno is set inside of get_socket(). Move last sock_set_errno() inside
kevman 0:38ceb79fef03 3549 lwip_close.
kevman 0:38ceb79fef03 3550
kevman 0:38ceb79fef03 3551 2007-03-09 Simon Goldschmidt
kevman 0:38ceb79fef03 3552 * memp.c: Fixed bug #11400: New etharp queueing introduced bug: memp_memory
kevman 0:38ceb79fef03 3553 was allocated too small.
kevman 0:38ceb79fef03 3554
kevman 0:38ceb79fef03 3555 2007-03-06 Simon Goldschmidt
kevman 0:38ceb79fef03 3556 * tcpip.c: Initialize dhcp timers in tcpip_thread (if LWIP_DHCP) to protect
kevman 0:38ceb79fef03 3557 the stack from concurrent access.
kevman 0:38ceb79fef03 3558
kevman 0:38ceb79fef03 3559 2007-03-06 Frédéric Bernon, Dmitry Potapov
kevman 0:38ceb79fef03 3560 * tcpip.c, ip_frag.c, ethernetif.c: Fix some build problems, and a redundancy
kevman 0:38ceb79fef03 3561 call to "lwip_stats.link.recv++;" in low_level_input() & ethernetif_input().
kevman 0:38ceb79fef03 3562
kevman 0:38ceb79fef03 3563 2007-03-06 Simon Goldschmidt
kevman 0:38ceb79fef03 3564 * ip_frag.c, ip_frag.h: Reduce code size: don't include code in those files
kevman 0:38ceb79fef03 3565 if IP_FRAG == 0 and IP_REASSEMBLY == 0
kevman 0:38ceb79fef03 3566
kevman 0:38ceb79fef03 3567 2007-03-06 Frédéric Bernon, Simon Goldschmidt
kevman 0:38ceb79fef03 3568 * opt.h, ip_frag.h, tcpip.h, tcpip.c, ethernetif.c: add new configuration
kevman 0:38ceb79fef03 3569 option named ETHARP_TCPIP_ETHINPUT, which enable the new tcpip_ethinput.
kevman 0:38ceb79fef03 3570 Allow to do ARP processing for incoming packets inside tcpip_thread
kevman 0:38ceb79fef03 3571 (protecting ARP layer against concurrent access). You can also disable
kevman 0:38ceb79fef03 3572 old code using tcp_input with new define ETHARP_TCPIP_INPUT set to 0.
kevman 0:38ceb79fef03 3573 Older ports have to use tcpip_ethinput.
kevman 0:38ceb79fef03 3574
kevman 0:38ceb79fef03 3575 2007-03-06 Simon Goldschmidt (based on patch from Dmitry Potapov)
kevman 0:38ceb79fef03 3576 * err.h, err.c: fixed compiler warning "initialization dircards qualifiers
kevman 0:38ceb79fef03 3577 from pointer target type"
kevman 0:38ceb79fef03 3578
kevman 0:38ceb79fef03 3579 2007-03-05 Frédéric Bernon
kevman 0:38ceb79fef03 3580 * opt.h, sockets.h: add new configuration options (LWIP_POSIX_SOCKETS_IO_NAMES,
kevman 0:38ceb79fef03 3581 ETHARP_TRUST_IP_MAC, review SO_REUSE)
kevman 0:38ceb79fef03 3582
kevman 0:38ceb79fef03 3583 2007-03-04 Frédéric Bernon
kevman 0:38ceb79fef03 3584 * api_msg.c: Remove some compiler warnings : parameter "pcb" was never
kevman 0:38ceb79fef03 3585 referenced.
kevman 0:38ceb79fef03 3586
kevman 0:38ceb79fef03 3587 2007-03-04 Frédéric Bernon
kevman 0:38ceb79fef03 3588 * api_lib.c: Fix "[patch #5764] api_lib.c cleanup: after patch #5687" (from
kevman 0:38ceb79fef03 3589 Dmitry Potapov).
kevman 0:38ceb79fef03 3590 The api_msg struct stay on the stack (not moved to netconn struct).

kevman 0:38ceb79fef03 3592 2007-03-04 Simon Goldschmidt (based on patch from Dmitry Potapov)
kevman 0:38ceb79fef03 3593 * pbuf.c: Fix BUG#19168 - pbuf_free can cause deadlock (if
kevman 0:38ceb79fef03 3594 SYS_LIGHTWEIGHT_PROT=1 & freeing PBUF_RAM when mem_sem is not available)
kevman 0:38ceb79fef03 3595 Also fixed cast warning in pbuf_alloc()

kevman 0:38ceb79fef03 3600
kevman 0:38ceb79fef03 3601 2007-03-03 Frédéric Bernon
kevman 0:38ceb79fef03 3602 * udp.c: remove obsolete line "static struct udp_pcb *pcb_cache = NULL;"
kevman 0:38ceb79fef03 3603 It is static, and never used in udp.c except udp_init().

kevman 0:38ceb79fef03 3605 2007-03-02 Simon Goldschmidt
kevman 0:38ceb79fef03 3606 * tcpip.c: Moved call to ip_init(), udp_init() and tcp_init() from
kevman 0:38ceb79fef03 3607 tcpip_thread() to tcpip_init(). This way, raw API connections can be
kevman 0:38ceb79fef03 3608 initialized before tcpip_thread is running (e.g. before OS is started)
kevman 0:38ceb79fef03 3609
kevman 0:38ceb79fef03 3610 2007-03-02 Frédéric Bernon
kevman 0:38ceb79fef03 3611 * rawapi.txt: Fix documentation mismatch with etharp.h about etharp_tmr's call
kevman 0:38ceb79fef03 3612 interval.

kevman 0:38ceb79fef03 3716
kevman 0:38ceb79fef03 3717 2006-02-27 Leon Woestenberg <leon.woestenberg@gmx.net>
kevman 0:38ceb79fef03 3718 * pbuf.c: Fix alignment; pbuf_init() would not work unless

kevman 0:38ceb79fef03 3729 * tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
kevman 0:38ceb79fef03 3730 Added Curt McDowell's optimized checksumming routine for future
kevman 0:38ceb79fef03 3731 inclusion. Need to create test case for unaliged, aligned, odd,
kevman 0:38ceb79fef03 3732 even length combination of cases on various endianess machines.
kevman 0:38ceb79fef03 3733
kevman 0:38ceb79fef03 3734 2005-12-09 Christiaan Simons

kevman 0:38ceb79fef03 3737 2005-11-25 Christiaan Simons
kevman 0:38ceb79fef03 3738 * udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
kevman 0:38ceb79fef03 3739 * *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
kevman 0:38ceb79fef03 3740 u32_t, s32_t typedefs. This solves most debug word-length assumes.

kevman 0:38ceb79fef03 3760 * etharp.*: Disabled multiple packets on the ARP queue.
kevman 0:38ceb79fef03 3761 This clashes with TCP queueing.
kevman 0:38ceb79fef03 3762
kevman 0:38ceb79fef03 3763 2004-11-28 Leon Woestenberg <leon.woestenberg@gmx.net>
kevman 0:38ceb79fef03 3764 * etharp.*: Fixed race condition from ARP request to ARP timeout.
kevman 0:38ceb79fef03 3765 Halved the ARP period, doubled the period counts.
kevman 0:38ceb79fef03 3766 ETHARP_MAX_PENDING now should be at least 2. This prevents
kevman 0:38ceb79fef03 3767 the counter from reaching 0 right away (which would allow
kevman 0:38ceb79fef03 3768 too little time for ARP responses to be received).

kevman 0:38ceb79fef03 3771 * dhcp.c: Decline messages were not multicast but unicast.
kevman 0:38ceb79fef03 3772 * etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
kevman 0:38ceb79fef03 3773 Do not try hard to insert arbitrary packet's source address,
kevman 0:38ceb79fef03 3774 etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
kevman 0:38ceb79fef03 3775 etharp_query() now always DOES call ETHARP_TRY_HARD so that users
kevman 0:38ceb79fef03 3776 querying an address will see it appear in the cache (DHCP could
kevman 0:38ceb79fef03 3777 suffer from this when a server invalidly gave an in-use address.)
kevman 0:38ceb79fef03 3778 * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
kevman 0:38ceb79fef03 3779 comparing network addresses (identifiers), not the network masks
kevman 0:38ceb79fef03 3780 themselves.
kevman 0:38ceb79fef03 3781 * ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
kevman 0:38ceb79fef03 3782 IP address actually belongs to the network of the given interface.
kevman 0:38ceb79fef03 3783

kevman 0:38ceb79fef03 3785 * tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.

kevman 0:38ceb79fef03 3790 * tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
kevman 0:38ceb79fef03 3791 even if one is already pending, if the rcv_wnd is above a threshold
kevman 0:38ceb79fef03 3792 (currently TCP_WND/2). This avoids waiting for a timer to expire to send a
kevman 0:38ceb79fef03 3793 delayed ACK in order to open the window if the stack is only receiving data.
kevman 0:38ceb79fef03 3794
kevman 0:38ceb79fef03 3795 2004-09-12 Kieran Mansley <kjm25@cam.ac.uk>

kevman 0:38ceb79fef03 3798 2004-08-20 Tony Mountifield <tony@softins.co.uk>
kevman 0:38ceb79fef03 3799 * etharp.c: Make sure the first pbuf queued on an ARP entry
kevman 0:38ceb79fef03 3800 is properly ref counted.
kevman 0:38ceb79fef03 3801
kevman 0:38ceb79fef03 3802 2004-07-27 Tony Mountifield <tony@softins.co.uk>
kevman 0:38ceb79fef03 3803 * debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
kevman 0:38ceb79fef03 3804 warnings about comparison.
kevman 0:38ceb79fef03 3805 * pbuf.c: Stopped compiler complaining of empty if statement
kevman 0:38ceb79fef03 3806 when LWIP_DEBUGF() empty. Closed an unclosed comment.
kevman 0:38ceb79fef03 3807 * tcp.c: Stopped compiler complaining of empty if statement
kevman 0:38ceb79fef03 3808 when LWIP_DEBUGF() empty.
kevman 0:38ceb79fef03 3809 * ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
kevman 0:38ceb79fef03 3810 * inet.c: Added a couple of casts to quiet the compiler.
kevman 0:38ceb79fef03 3811 No need to test isascii(c) before isdigit(c) or isxdigit(c).
kevman 0:38ceb79fef03 3812
kevman 0:38ceb79fef03 3813 2004-07-22 Tony Mountifield <tony@softins.co.uk>
kevman 0:38ceb79fef03 3814 * inet.c: Made data types consistent in inet_ntoa().
kevman 0:38ceb79fef03 3815 Added casts for return values of checksum routines, to pacify compiler.
kevman 0:38ceb79fef03 3816 * ip_frag.c, tcp_out.c, sockets.c, pbuf.c
kevman 0:38ceb79fef03 3817 Small corrections to some debugging statements, to pacify compiler.
kevman 0:38ceb79fef03 3818
kevman 0:38ceb79fef03 3819 2004-07-21 Tony Mountifield <tony@softins.co.uk>
kevman 0:38ceb79fef03 3820 * etharp.c: Removed spurious semicolon and added missing end-of-comment.
kevman 0:38ceb79fef03 3821 * ethernetif.c Updated low_level_output() to match prototype for
kevman 0:38ceb79fef03 3822 netif->linkoutput and changed low_level_input() similarly for consistency.
kevman 0:38ceb79fef03 3823 * api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
kevman 0:38ceb79fef03 3824 of raw_recv() in raw.h and so avoid compiler error.
kevman 0:38ceb79fef03 3825 * sockets.c: Added trivial (int) cast to keep compiler happier.
kevman 0:38ceb79fef03 3826 * ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.

kevman 0:38ceb79fef03 3833 * sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure
kevman 0:38ceb79fef03 3834 your cc.h file defines this either 1 or 0. If non-defined,
kevman 0:38ceb79fef03 3835 defaults to 1.
kevman 0:38ceb79fef03 3836 * .c: Added <string.h> and <errno.h> includes where used.
kevman 0:38ceb79fef03 3837 * etharp.c: Made some array indices unsigned.
kevman 0:38ceb79fef03 3838

kevman 0:38ceb79fef03 3844 * etharp.c: In find_entry(), instead of a list traversal per candidate, do a
kevman 0:38ceb79fef03 3845 single-pass lookup for different candidates. Should exploit locality.
kevman 0:38ceb79fef03 3846
kevman 0:38ceb79fef03 3847 2004-04-29 Leon Woestenberg <leon.woestenberg@gmx.net>
kevman 0:38ceb79fef03 3848 * tcp*.c: Cleaned up source comment documentation for Doxygen processing.
kevman 0:38ceb79fef03 3849 * opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC.
kevman 0:38ceb79fef03 3850 * etharp.c: update_arp_entry() only adds new ARP entries when adviced to by
kevman 0:38ceb79fef03 3851 the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option.

kevman 0:38ceb79fef03 3856 * etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution
kevman 0:38ceb79fef03 3857 suggested by Timmy Brolin. Fix for 32-bit processors that cannot access
kevman 0:38ceb79fef03 3858 non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix
kevman 0:38ceb79fef03 3859 is to prefix the 14-bit Ethernet headers with two padding bytes.

kevman 0:38ceb79fef03 3862 * ip_addr.c: Fix in the ip_addr_isbroadcast() check.
kevman 0:38ceb79fef03 3863 * etharp.c: Fixed the case where the packet that initiates the ARP request
kevman 0:38ceb79fef03 3864 is not queued, and gets lost. Fixed the case where the packets destination
kevman 0:38ceb79fef03 3865 address is already known; we now always queue the packet and perform an ARP

kevman 0:38ceb79fef03 3922 Reported by Savin Zlobec.
kevman 0:38ceb79fef03 3923
kevman 0:38ceb79fef03 3924 * PBUF_POOL chains had their tot_len field not set for non-first
kevman 0:38ceb79fef03 3925 pbufs. Fixed in pbuf_alloc().
kevman 0:38ceb79fef03 3926
kevman 0:38ceb79fef03 3927 ++ New features:
kevman 0:38ceb79fef03 3928
kevman 0:38ceb79fef03 3929 * Added PPP stack contributed by Marc Boucher
kevman 0:38ceb79fef03 3930
kevman 0:38ceb79fef03 3931 ++ Changes:
kevman 0:38ceb79fef03 3932
kevman 0:38ceb79fef03 3933 * Now drops short packets for ICMP/UDP/TCP protocols. More robust.
kevman 0:38ceb79fef03 3934
kevman 0:38ceb79fef03 3935 * ARP queueuing now queues the latest packet instead of the first.
kevman 0:38ceb79fef03 3936 This is the RFC recommended behaviour, but can be overridden in
kevman 0:38ceb79fef03 3937 lwipopts.h.
kevman 0:38ceb79fef03 3938
kevman 0:38ceb79fef03 3939 (0.6.2)
kevman 0:38ceb79fef03 3940
kevman 0:38ceb79fef03 3941 ++ Bugfixes:
kevman 0:38ceb79fef03 3942
kevman 0:38ceb79fef03 3943 * TCP has been fixed to deal with the new use of the pbuf->ref
kevman 0:38ceb79fef03 3944 counter.
kevman 0:38ceb79fef03 3945
kevman 0:38ceb79fef03 3946 * DHCP dhcp_inform() crash bug fixed.
kevman 0:38ceb79fef03 3947
kevman 0:38ceb79fef03 3948 ++ Changes:
kevman 0:38ceb79fef03 3949
kevman 0:38ceb79fef03 3950 * Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
kevman 0:38ceb79fef03 3951 pbuf_refresh(). This has sped up pbuf pool operations considerably.
kevman 0:38ceb79fef03 3952 Implemented by David Haas.
kevman 0:38ceb79fef03 3953
kevman 0:38ceb79fef03 3954 (0.6.1)
kevman 0:38ceb79fef03 3955
kevman 0:38ceb79fef03 3956 ++ New features:
kevman 0:38ceb79fef03 3957
kevman 0:38ceb79fef03 3958 * The packet buffer implementation has been enhanced to support
kevman 0:38ceb79fef03 3959 zero-copy and copy-on-demand for packet buffers which have their
kevman 0:38ceb79fef03 3960 payloads in application-managed memory.
kevman 0:38ceb79fef03 3961 Implemented by David Haas.
kevman 0:38ceb79fef03 3962
kevman 0:38ceb79fef03 3963 Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
kevman 0:38ceb79fef03 3964 if an outgoing packet can be directly sent on the link, or perform
kevman 0:38ceb79fef03 3965 a copy-on-demand when necessary.
kevman 0:38ceb79fef03 3966
kevman 0:38ceb79fef03 3967 The application can safely assume the packet is sent, and the RAM
kevman 0:38ceb79fef03 3968 is available to the application directly after calling udp_send()
kevman 0:38ceb79fef03 3969 or similar function.
kevman 0:38ceb79fef03 3970
kevman 0:38ceb79fef03 3971 ++ Bugfixes:

kevman 0:38ceb79fef03 3975 Implemented by Leon Woestenberg.
kevman 0:38ceb79fef03 3976
kevman 0:38ceb79fef03 3977 ++ Changes:
kevman 0:38ceb79fef03 3978
kevman 0:38ceb79fef03 3979 * IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
kevman 0:38ceb79fef03 3980 to a '0.0.0.0' IP address.
kevman 0:38ceb79fef03 3981
kevman 0:38ceb79fef03 3982 * The packet buffer implementation is changed. The pbuf->ref counter
kevman 0:38ceb79fef03 3983 meaning has changed, and several pbuf functions have been
kevman 0:38ceb79fef03 3984 adapted accordingly.
kevman 0:38ceb79fef03 3985
kevman 0:38ceb79fef03 3986 * netif drivers have to be changed to set the hardware address length field
kevman 0:38ceb79fef03 3987 that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).
kevman 0:38ceb79fef03 3988 See the contrib/ports/c16x cs8900 driver as a driver example.
kevman 0:38ceb79fef03 3989
kevman 0:38ceb79fef03 3990 * netif's have a dhcp field that must be initialized to NULL by the driver.
kevman 0:38ceb79fef03 3991 See the contrib/ports/c16x cs8900 driver as a driver example.

kevman 0:38ceb79fef03 4058
kevman 0:38ceb79fef03 4059 * Situations when all TCP buffers were used could lead to
kevman 0:38ceb79fef03 4060 starvation.
kevman 0:38ceb79fef03 4061
kevman 0:38ceb79fef03 4062 * TCP MSS option wasn't parsed correctly.

kevman 0:38ceb79fef03 4175
kevman 0:38ceb79fef03 4176 * Memory management has been radically changed; instead of
kevman 0:38ceb79fef03 4177 allocating memory from a shared heap, memory for objects that are
kevman 0:38ceb79fef03 4178 rapidly allocated and deallocated is now kept in pools. Allocation
kevman 0:38ceb79fef03 4179 and deallocation from those memory pools is very fast. The shared
kevman 0:38ceb79fef03 4180 heap is still present but is used less frequently.
kevman 0:38ceb79fef03 4181
kevman 0:38ceb79fef03 4182 * The memory, memory pool, and packet buffer subsystems now support

kevman 0:38ceb79fef03 4190 TTLs, statistics gathering, etc. All configuration parameters are
kevman 0:38ceb79fef03 4191 now kept in a single header file "lwipopts.h".
kevman 0:38ceb79fef03 4192
kevman 0:38ceb79fef03 4193 * The directory structure has been changed slightly so that all
kevman 0:38ceb79fef03 4194 architecture specific files are kept under the src/arch
kevman 0:38ceb79fef03 4195 hierarchy.
kevman 0:38ceb79fef03 4196
kevman 0:38ceb79fef03 4197 * Error propagation has been improved, both in the protocol modules
kevman 0:38ceb79fef03 4198 and in the API.
kevman 0:38ceb79fef03 4199
kevman 0:38ceb79fef03 4200 * The code for the RTXC architecture has been implemented, tested
kevman 0:38ceb79fef03 4201 and put to use.

kevman 0:38ceb79fef03 4203 * Bugs have been found and corrected in the TCP, UDP, IP, API, and
kevman 0:38ceb79fef03 4204 the Internet checksum modules.
kevman 0:38ceb79fef03 4205
kevman 0:38ceb79fef03 4206 * Bugs related to porting between a 32-bit and a 16-bit architecture
kevman 0:38ceb79fef03 4207 have been found and corrected.
kevman 0:38ceb79fef03 4208
kevman 0:38ceb79fef03 4209 * The license has been changed slightly to conform more with the

kevman 0:38ceb79fef03 4211
kevman 0:38ceb79fef03 4212 (0.3.1) Changes since version 0.3
kevman 0:38ceb79fef03 4213
kevman 0:38ceb79fef03 4214 * Fix of a fatal bug in the buffer management. Pbufs with allocated
kevman 0:38ceb79fef03 4215 RAM never returned the RAM when the pbuf was deallocated.
kevman 0:38ceb79fef03 4216
kevman 0:38ceb79fef03 4217 * TCP congestion control, window updates and retransmissions did not
kevman 0:38ceb79fef03 4218 work correctly. This has now been fixed.
kevman 0:38ceb79fef03 4219
kevman 0:38ceb79fef03 4220 * Bugfixes in the API.
kevman 0:38ceb79fef03 4221
kevman 0:38ceb79fef03 4222 (0.3) Changes since version 0.2
kevman 0:38ceb79fef03 4223
kevman 0:38ceb79fef03 4224 * New and improved directory structure. All include files are now
kevman 0:38ceb79fef03 4225 kept in a dedicated include/ directory.
kevman 0:38ceb79fef03 4226
kevman 0:38ceb79fef03 4227 * The API now has proper error handling. A new function,
kevman 0:38ceb79fef03 4228 netconn_err(), now returns an error code for the connection in
kevman 0:38ceb79fef03 4229 case of errors.
kevman 0:38ceb79fef03 4230
kevman 0:38ceb79fef03 4231 * Improvements in the memory management subsystem. The system now
kevman 0:38ceb79fef03 4232 keeps a pointer to the lowest free memory block. A new function,
kevman 0:38ceb79fef03 4233 mem_malloc2() tries to allocate memory once, and if it fails tries
kevman 0:38ceb79fef03 4234 to free some memory and retry the allocation.
kevman 0:38ceb79fef03 4235
kevman 0:38ceb79fef03 4236 * Much testing has been done with limited memory
kevman 0:38ceb79fef03 4237 configurations. lwIP now does a better job when overloaded.
kevman 0:38ceb79fef03 4238
kevman 0:38ceb79fef03 4239 * Some bugfixes and improvements to the buffer (pbuf) subsystem.
kevman 0:38ceb79fef03 4240
kevman 0:38ceb79fef03 4241 * Many bugfixes in the TCP code:
kevman 0:38ceb79fef03 4242
kevman 0:38ceb79fef03 4243 - Fixed a bug in tcp_close().
kevman 0:38ceb79fef03 4244
kevman 0:38ceb79fef03 4245 - The TCP receive window was incorrectly closed when out of
kevman 0:38ceb79fef03 4246 sequence segments was received. This has been fixed.
kevman 0:38ceb79fef03 4247
kevman 0:38ceb79fef03 4248 - Connections are now timed-out of the FIN-WAIT-2 state.
kevman 0:38ceb79fef03 4249
kevman 0:38ceb79fef03 4250 - The initial congestion window could in some cases be too
kevman 0:38ceb79fef03 4251 large. This has been fixed.
kevman 0:38ceb79fef03 4252
kevman 0:38ceb79fef03 4253 - The retransmission queue could in some cases be screwed up. This
kevman 0:38ceb79fef03 4254 has been fixed.
kevman 0:38ceb79fef03 4255
kevman 0:38ceb79fef03 4256 - TCP RST flag now handled correctly.
kevman 0:38ceb79fef03 4257
kevman 0:38ceb79fef03 4258 - Out of sequence data was in some cases never delivered to the
kevman 0:38ceb79fef03 4259 application. This has been fixed.
kevman 0:38ceb79fef03 4260
kevman 0:38ceb79fef03 4261 - Retransmitted segments now contain the correct acknowledgment
kevman 0:38ceb79fef03 4262 number and advertised window.
kevman 0:38ceb79fef03 4263
kevman 0:38ceb79fef03 4264 - TCP retransmission timeout backoffs are not correctly computed
kevman 0:38ceb79fef03 4265 (ala BSD). After a number of retransmissions, TCP now gives up
kevman 0:38ceb79fef03 4266 the connection.
kevman 0:38ceb79fef03 4267
kevman 0:38ceb79fef03 4268 * TCP connections now are kept on three lists, one for active
kevman 0:38ceb79fef03 4269 connections, one for listening connections, and one for
kevman 0:38ceb79fef03 4270 connections that are in TIME-WAIT. This greatly speeds up the fast
kevman 0:38ceb79fef03 4271 timeout processing for sending delayed ACKs.
kevman 0:38ceb79fef03 4272
kevman 0:38ceb79fef03 4273 * TCP now provides proper feedback to the application when a
kevman 0:38ceb79fef03 4274 connection has been successfully set up.
kevman 0:38ceb79fef03 4275
kevman 0:38ceb79fef03 4276 * More comments have been added to the code. The code has also been
kevman 0:38ceb79fef03 4277 somewhat cleaned up.
kevman 0:38ceb79fef03 4278
kevman 0:38ceb79fef03 4279 (0.2) Initial public release.
