31 2010-06-16: Simon Goldschmidt
32 * ip.c: Added an optional define (LWIP_IP_ACCEPT_UDP_PORT) that can allow
33 link-layer-addressed UDP traffic to be received while a netif is down (just
34 like DHCP during configuration)
36 2010-05-22: Simon Goldschmidt
37 * many many files: bug #27352: removed packing from ip_addr_t, the packed
38 version is now only used in protocol headers. Added global storage for
39 current src/dest IP address while in input functions.
41 2010-05-16: Simon Goldschmidt
42 * def.h: task #10391: Add preprocessor-macros for compile-time htonl
43 calculation (and use them throughout the stack where applicable)
45 2010-05-16: Simon Goldschmidt
46 * opt.h, memp_std.h, memp.c, ppp_oe.h/.c: PPPoE now uses its own MEMP pool

62 2010-04-30: Simon Goldschmidt
63 * udp.h/.c, pbuf.h/.c: task #6849: added udp_send(_to/_if) functions that
64 take a precalculated checksum, added pbuf_fill_chksum() to copy data
65 into a pbuf and at the same time calculating the checksum for that data
67 2010-04-29: Simon Goldschmidt
68 * ip_addr.h, etharp.h/.c, autoip.c: Create overridable macros for copying
69 2-byte-aligned IP addresses and MAC addresses

98 2010-03-07: Simon Goldschmidt
99 * sockets.c: bug #28775 (select/event_callback: only check select_cb_list
100 on change) plus use SYS_LIGHTWEIGHT_PROT to protect the select code.
101 This should speed up receiving data on sockets as the select code in
102 event_callback is only executed when select is waiting.
104 2010-03-06: Simon Goldschmidt
105 * tcp_out.c: task #7013 (Create option to have all packets delivered to
106 netif->output in one piece): Always copy to try to create single pbufs

115 2010-03-05: Jakob Ole Stoklundsen / Simon Goldschmidt
116 * opt.h, tcp.h, tcp_impl.h, tcp.c, tcp_in.c, tcp_out.c: task #7040:
117 Work on tcp_enqueue: Don't waste memory when chaining segments,
118 added option TCP_OVERSIZE to prevent creating many small pbufs when
119 calling tcp_write with many small blocks of data. Instead, pbufs are
120 allocated larger than needed and the space is used for later calls to
123 2010-02-21: Simon Goldschmidt
124 * stats.c/.h: Added const char* name to mem- and memp-stats for easier
127 2010-02-21: Simon Goldschmidt

146 and dhcp work with user-allocated structs instead of callin mem_malloc
148 2010-02-12: Simon Goldschmidt/Jeff Barber
149 * tcp.c/h: patch #6865 (SO_REUSEADDR for TCP): if pcb.so_options has
150 SOF_REUSEADDR set, allow binding to endpoint in TIME_WAIT
152 2010-02-12: Simon Goldschmidt
153 * sys layer: task #10139 (Prefer statically allocated memory): converted
154 mbox and semaphore functions to take pointers to sys_mbox_t/sys_sem_t;
155 converted sys_mbox_new/sys_sem_new to take pointers and return err_t;
156 task #7212: Add Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX
157 to let sys.h use binary semaphores instead of mutexes - as before)
159 2010-02-09: Simon Goldschmidt (Simon Kallweit)
160 * timers.c/.h: Added function sys_restart_timeouts() from patch #7085

165 netif.c) - loopif does not have to be created by the port any more,
166 just define LWIP_HAVE_LOOPIF to 1.
168 2010-02-08: Simon Goldschmidt
169 * inet.h, ip_addr.c/.h: Added reentrant versions of inet_ntoa/ipaddr_ntoa

183 * opt.h, memp_std.h, dns.h, netdb.c, memp.c: Let netdb use a memp pool
184 for allocating memory when getaddrinfo() is called.
186 2010-01-31: Simon Goldschmidt
187 * dhcp.h, dhcp.c: Reworked the code that parses DHCP options: parse
188 them once instead of parsing for every option. This also removes

190 correctly retrieve the BOOTP file.
192 2010-01-30: simon Goldschmidt
193 * sockets.c: Use SYS_LIGHTWEIGHT_PROT instead of a semaphore to protect

237 * opt.h, etharp.h/.c, init.c, tcpip.c: Added an additional option
238 LWIP_ETHERNET to support ethernet without ARP (necessary for pure PPPoE)
243 2011-04-20: Simon Goldschmidt
244 * sys_arch.txt: sys_arch_timeouts() is not needed any more.
246 2011-04-13: Simon Goldschmidt
247 * tcp.c, udp.c: Fixed bug #33048 (Bad range for IP source port numbers) by
248 using ports in the IANA private/dynamic range (49152 through 65535).

499 * netif.c: Fixed bug #28877 (Duplicate ARP gratuitous packet with
500 LWIP_NETIF_LINK_CALLBACK set on) by only sending if both link- and
501 admin-status of a netif are up
503 2010-02-14: Simon Goldschmidt
504 * opt.h: Disable ETHARP_TRUST_IP_MAC by default since it slows down packet
505 reception and is not really necessary
507 2010-02-14: Simon Goldschmidt
508 * etharp.c/.h: Fixed ARP input processing: only add a new entry if a
509 request was directed as us (RFC 826, Packet Reception), otherwise
510 only update existing entries; internalized some functions
512 2010-02-14: Simon Goldschmidt
513 * netif.h, etharp.c, tcpip.c: Fixed bug #28183 (ARP and TCP/IP cannot be
514 disabled on netif used for PPPoE) by adding a new netif flag
515 (NETIF_FLAG_ETHERNET) that tells the stack the device is an ethernet
516 device but prevents usage of ARP (so that ethernet_input can be used
519 2010-02-12: Simon Goldschmidt
520 * netif.c: netif_set_link_up/down: only do something if the link state
523 2010-02-12: Simon Goldschmidt/Stephane Lesage
524 * api_msg.c: Fixed bug #28865 (Cannot close socket/netconn in non-blocking
527 2010-02-12: Simon Goldschmidt
528 * mem.h: Fixed bug #28866 (mem_realloc function defined in mem.h)
530 2010-02-09: Simon Goldschmidt
531 * api_lib.c, api_msg.c, sockets.c, api.h, api_msg.h: Fixed bug #22110
532 (recv() makes receive window update for data that wasn't received by
535 2010-02-09: Simon Goldschmidt/Stephane Lesage
536 * sockets.c: Fixed bug #28853 (lwip_recvfrom() returns 0 on receive time-out
537 or any netconn_recv() error)
539 2010-02-09: Simon Goldschmidt
540 * ppp.c: task #10154 (PPP: Update snmp in/out counters for tx/rx packets)
542 2010-02-09: Simon Goldschmidt
543 * netif.c: For loopback packets, adjust the stats- and snmp-counters
544 for the loopback netif.
546 2010-02-08: Simon Goldschmidt
547 * igmp.c/.h, ip.h: Moved most defines from igmp.h to igmp.c for clarity
548 since they are not used anywhere else.
550 2010-02-08: Simon Goldschmidt (Stéphane Lesage)
551 * igmp.c, igmp.h, stats.c, stats.h: Improved IGMP stats
552 (patch from bug #28798)

556 another bug when LWIP_RAND() returns zero.
558 2010-02-04: Simon Goldschmidt
559 * nearly every file: Use macros defined in ip_addr.h (some of them new)
560 to work with IP addresses (preparation for bug #27352 - Change ip_addr
561 from struct to typedef (u32_t) - and better code).
563 2010-01-31: Simon Goldschmidt
564 * netif.c: Don't call the link-callback from netif_set_up/down() since
565 this invalidly retriggers DHCP.
567 2010-01-29: Simon Goldschmidt
568 * ip_addr.h, inet.h, def.h, inet.c, def.c, more: Cleanly separate the
569 portability file inet.h and its contents from the stack: moved htonX-
570 functions to def.h (and the new def.c - they are not ipv4 dependent),
571 let inet.h depend on ip_addr.h and not the other way round.
572 This fixes bug #28732.
574 2010-01-28: Kieran Mansley
575 * tcp.c: Ensure ssthresh >= 2*MSS
577 2010-01-27: Simon Goldschmidt
578 * tcp.h, tcp.c, tcp_in.c: Fixed bug #27871: Calling tcp_abort() in recv
579 callback can lead to accessing unallocated memory. As a consequence,
580 ERR_ABRT means the application has called tcp_abort()!
582 2010-01-25: Simon Goldschmidt
583 * snmp_structs.h, msg_in.c: Partly fixed bug #22070 (MIB_OBJECT_WRITE_ONLY
584 not implemented in SNMP): write-only or not-accessible are still
585 returned by getnext (though not by get)
587 2010-01-24: Simon Goldschmidt
588 * snmp: Renamed the private mib node from 'private' to 'mib_private' to
589 not use reserved C/C++ keywords
591 2010-01-23: Simon Goldschmidt
592 * sockets.c: Fixed bug #28716: select() returns 0 after waiting for less

612 error return value to struct api_msg_msg
614 2010-01-17: Simon Goldschmidt
615 * api.h, api_lib.c, sockets.c: Changed netconn_recv() and netconn_accept()
616 to return err_t (bugs #27709 and #28087)
618 2010-01-14: Simon Goldschmidt
619 * ...: Use typedef for function prototypes throughout the stack.
621 2010-01-13: Simon Goldschmidt
622 * api_msg.h/.c, api_lib.c: Fixed bug #26672 (close connection when receive
623 window = 0) by correctly draining recvmbox/acceptmbox
625 2010-01-11: Simon Goldschmidt
626 * pap.c: Fixed bug #13315 (PPP PAP authentication can result in
627 erroneous callbacks) by copying the code from recent pppd
629 2010-01-10: Simon Goldschmidt
630 * raw.c: Fixed bug #28506 (raw_bind should filter received packets)

638 2010-01-08: Simon Goldschmidt
639 * dns.c: Copy hostname for DNS_LOCAL_HOSTLIST_IS_DYNAMIC==1 since string
640 passed to dns_local_addhost() might be volatile
642 2010-01-07: Simon Goldschmidt
643 * timers.c, tcp.h: Call tcp_timer_needed() with NO_SYS==1, too
645 2010-01-06: Simon Goldschmidt
646 * netdb.h: Fixed bug #28496: missing include guards in netdb.h
648 2009-12-31: Simon Goldschmidt
649 * many ppp files: Reorganised PPP source code from ucip structure to pppd
650 structure to easily compare our code against the pppd code (around v2.3.1)
652 2009-12-27: Simon Goldschmidt
653 * tcp_in.c: Another fix for bug #28241 (ooseq processing) and adapted

768 testing for valid reply
770 2009-10-19: Simon Goldschmidt
771 * dhcp.c: Removed most calls to udp_connect since they aren't necessary
772 when using udp_sendto_if() - always stay connected to IP_ADDR_ANY.
774 2009-10-16: Simon Goldschmidt

832 * opt.h, sockets.c, pbuf.c, netbuf.h, pbuf.h: task #7013: Added option
833 LWIP_NETIF_TX_SINGLE_PBUF to try to create transmit packets from only
834 one pbuf to help MACs that don't support scatter-gather DMA.
836 2009-05-09 Simon Goldschmidt
837 * icmp.h, icmp.c: Shrinked ICMP code, added option to NOT check icoming

885 * autoip.c: checked in (slightly modified) patch #6683: Customizable AUTOIP
886 "seed" address. This should reduce AUTOIP conflicts if

889 2008-10-02 Jonathan Larmour and Rishi Khan
890 * sockets.c (lwip_accept): Return EWOULDBLOCK if would block on non-blocking

987 * ppp.c: bug #24228: Memory corruption with PPP and DHCP
989 2009-04-29 Frédéric Bernon
990 * raw.c, udp.c, init.c, opt.h, ip.h, sockets.h: bug #26309: Implement the
991 SO(F)_BROADCAST filter for all API layers. Avoid the unindented reception
992 of broadcast packets even when this option wasn't set. Port maintainers
993 which want to enable this filter have to set IP_SOF_BROADCAST=1 in opt.h.
994 If you want this option also filter broadcast on recv operations, you also
995 have to set IP_SOF_BROADCAST_RECV=1 in opt.h.
997 2009-04-28 Simon Goldschmidt, Jakob Stoklund Olesen

1004 right place in tcp_output and tcp_rexmit).
1006 2009-04-25 Simon Goldschmidt
1007 * memp.c, mem.c, memp.h, mem_std.h: bug #26213 "Problem with memory allocation
1008 when debugging": memp_sizes contained the wrong sizes (including sanity
1009 regions); memp pools for MEM_USE_POOLS were too small
1011 2009-04-24 Simon Goldschmidt, Frédéric Bernon
1012 * inet.c: patch #6765: Fix a small problem with the last changes (incorrect
1013 behavior, with with ip address string not ended by a '\0', a space or a
1016 2009-04-19 Simon Goldschmidt
1017 * rawapi.txt: Fixed bug #26069: Corrected documentation: if tcp_connect fails,
1018 pcb->err is called, not pcb->connected (with an error code).
1020 2009-04-19 Simon Goldschmidt
1021 * tcp_out.c: Fixed bug #26236: "TCP options (timestamp) don't work with
1022 no-copy-tcpwrite": deallocate option data, only concat segments with same flags
1024 2009-04-19 Simon Goldschmidt
1025 * tcp_out.c: Fixed bug #25094: "Zero-length pbuf" (options are now allocated
1026 in the header pbuf, not the data pbuf)

1105 2009-02-11 Simon Goldschmidt
1106 * opt.h, api_msg.c: added configurable default valud for netconn->recv_bufsize:
1107 RECV_BUFSIZE_DEFAULT (fixes bug #23726: pbuf pool exhaustion on slow recv())
1109 2009-02-10 Simon Goldschmidt
1110 * tcp.c: fixed bug #25467: Listen backlog is not reset on timeout in SYN_RCVD:

1129 2008-10-15 Simon Goldschmidt
1130 * ip_frag.c: fixed bug #24517: IP reassembly crashes on unaligned IP headers
1131 by packing the struct ip_reass_helper.
1133 2008-10-03 David Woodhouse, Jonathan Larmour
1134 * etharp.c (etharp_arp_input): Fix type aliasing problem copying ip address.
1136 2008-10-02 Jonathan Larmour
1137 * dns.c: Hard-code structure sizes, to avoid issues on some compilers where
1138 padding is included.
1140 2008-09-30 Jonathan Larmour
1141 * sockets.c (lwip_accept): check addr isn't NULL. If it's valid, do an
1142 assertion check that addrlen isn't NULL.

1149 inet.h -> moved declaration of struct in_addr from ip_addr.h to inet.h
1151 2008-08-14 Simon Goldschmidt
1152 * api_msg.c: fixed bug #23847: do_close_internal references freed memory (when
1153 tcp_close returns != ERR_OK)
1155 2008-07-08 Frédéric Bernon
1156 * stats.h: Fix some build bugs introduced with patch #6483 (missing some parameters
1157 in macros, mainly if MEM_STATS=0 and MEMP_STATS=0).
1159 2008-06-24 Jonathan Larmour
1160 * tcp_in.c: Fix for bug #23693 as suggested by Art R. Ensure cseg is unused
1161 if tcp_seg_copy fails.
1163 2008-06-17 Simon Goldschmidt
1164 * inet_chksum.c: Checked in some ideas of patch #6460 (loop optimizations)
1165 and created defines for swapping bytes and folding u32 to u16.
1167 2008-05-30 Kieran Mansley
1168 * tcp_in.c Remove redundant "if" statement, and use real rcv_wnd
1169 rather than rcv_ann_wnd when deciding if packets are in-window.
1170 Contributed by <arasmussen@consultant.datasys.swri.edu>
1172 2008-05-30 Kieran Mansley
1173 * mem.h: Fix BUG#23254. Change macro definition of mem_* to allow
1174 passing as function pointers when MEM_LIBC_MALLOC is defined.
1176 2008-05-09 Jonathan Larmour
1177 * err.h, err.c, sockets.c: Fix bug #23119: Reorder timeout error code to
1178 stop it being treated as a fatal error.
1180 2008-04-15 Simon Goldschmidt
1181 * dhcp.c: fixed bug #22804: dhcp_stop doesn't clear NETIF_FLAG_DHCP
1184 2008-03-27 Simon Goldschmidt
1185 * mem.c, tcpip.c, tcpip.h, opt.h: fixed bug #21433 (Calling mem_free/pbuf_free
1186 from interrupt context isn't safe): set LWIP_USE_HEAP_FROM_INTERRUPT to 1
1187 in lwipopts.h or use pbuf_free_callback(p)/mem_free_callback(m) to free pbufs
1188 or heap memory from interrupt context
1190 2008-03-26 Simon Goldschmidt
1191 * tcp_in.c, tcp.c: fixed bug #22249: division by zero could occur if a remote
1192 host sent a zero mss as TCP option.
1199 2008-03-10 Jonathan Larmour
1200 * inet_chksum.c: Allow choice of one of the sample algorithms to be
1201 made from lwipopts.h. Fix comment on how to override LWIP_CHKSUM.
1203 2008-01-22 Frédéric Bernon
1204 * tcp.c, tcp_in.c, tcp.h, opt.h: Rename LWIP_CALCULATE_EFF_SEND_MSS in
1205 TCP_CALCULATE_EFF_SEND_MSS to have coherent TCP options names.
1207 2008-01-14 Frédéric Bernon
1208 * rawapi.txt, api_msg.c, tcp.c, tcp_in.c, tcp.h: changes for task #7675 "Enable
1209 to refuse data on a TCP_EVENT_RECV call". Important, behavior changes for the
1210 tcp_recv callback (see rawapi.txt).
1212 2008-01-14 Frédéric Bernon, Marc Chaland
1213 * ip.c: Integrate patch #6369" ip_input : checking before realloc".
1215 2008-01-12 Frédéric Bernon
1216 * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
1217 netconn::sem per netconn::op_completed like suggested for the task #7490
1218 "Add return value to sys_mbox_post".
1220 2008-01-12 Frédéric Bernon
1221 * api_msg.c, opt.h: replace DEFAULT_RECVMBOX_SIZE per DEFAULT_TCP_RECVMBOX_SIZE,
1222 DEFAULT_UDP_RECVMBOX_SIZE and DEFAULT_RAW_RECVMBOX_SIZE (to optimize queues
1223 sizes), like suggested for the task #7490 "Add return value to sys_mbox_post".
1225 2008-01-10 Frédéric Bernon
1226 * tcpip.h, tcpip.c: add tcpip_callback_with_block function for the task #7490
1227 "Add return value to sys_mbox_post". tcpip_callback is always defined as
1228 "blocking" ("block" parameter = 1).
1230 2008-01-10 Frédéric Bernon
1231 * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
1232 netconn::mbox (sys_mbox_t) per netconn::sem (sys_sem_t) for the task #7490
1233 "Add return value to sys_mbox_post".
1235 2008-01-05 Frédéric Bernon
1236 * sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h, opt.h:
1237 Introduce changes for task #7490 "Add return value to sys_mbox_post" with some
1238 modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which
1239 indicate the number of pointers query by the mailbox. There is three defines
1240 in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the
1241 netconn::acceptmbox. Port maintainers, you can decide to just add this new
1242 parameter in your implementation, but to ignore it to keep the previous behavior.
1243 The new sys_mbox_trypost function return a value to know if the mailbox is
1244 full or if the message is posted. Take a look to sys_arch.txt for more details.
1245 This new function is used in tcpip_input (so, can be called in an interrupt
1246 context since the function is not blocking), and in recv_udp and recv_raw.
1248 2008-01-04 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
1249 * rawapi.txt, api.h, api_lib.c, api_msg.h, api_msg.c, sockets.c, tcp.h, tcp.c,
1250 tcp_in.c, init.c, opt.h: rename backlog options with TCP_ prefix, limit the
1251 "backlog" parameter in an u8_t, 0 is interpreted as "smallest queue", add
1252 documentation in the rawapi.txt file.
1254 2007-12-31 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
1255 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Add TCP persist timer
1257 2007-12-31 Frédéric Bernon, Luca Ceresoli
1258 * autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP packets
1259 in autoip". The change in etharp_raw could be removed, since all calls to
1260 etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be
1261 wrong in the future.
1263 2007-12-30 Frédéric Bernon, Tom Evans
1264 * ip.c: Fix bug #21846 "LwIP doesn't appear to perform any IP Source Address
1265 Filtering" reported by Tom Evans.
1267 2007-12-21 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
1268 * tcp.h, opt.h, api.h, api_msg.h, tcp.c, tcp_in.c, api_lib.c, api_msg.c,
1269 sockets.c, init.c: task #7252: Implement TCP listen backlog: Warning: raw API
1270 applications have to call 'tcp_accepted(pcb)' in their accept callback to
1271 keep accepting new connections.
1273 2007-12-13 Frédéric Bernon
1274 * api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum dns_result"
1275 by err_t type. Add a new err_t code "ERR_INPROGRESS".
1277 2007-12-12 Frédéric Bernon
1278 * dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles
1279 are the one which have ram usage.
1281 2007-12-05 Frédéric Bernon
1282 * netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static
1283 set of variables (=0) or a local one (=1). In this last case, your port should
1284 provide a function "struct hostent* sys_thread_hostent( struct hostent* h)"
1285 which have to do a copy of "h" and return a pointer ont the "per-thread" copy.
1287 2007-12-03 Simon Goldschmidt
1288 * ip.c: ip_input: check if a packet is for inp first before checking all other
1289 netifs on netif_list (speeds up packet receiving in most cases)
1291 2007-11-30 Simon Goldschmidt
1292 * udp.c, raw.c: task #7497: Sort lists (pcb, netif, ...) for faster access
1293 UDP: move a (connected) pcb selected for input to the front of the list of
1294 pcbs so that it is found faster next time. Same for RAW pcbs that have eaten
1297 2007-11-28 Simon Goldschmidt
1298 * etharp.c, stats.c, stats.h, opt.h: Introduced ETHARP_STATS
1300 2007-11-25 Simon Goldschmidt
1301 * dhcp.c: dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy
1304 2007-11-24 Simon Goldschmidt
1305 * netdb.h, netdb.c, sockets.h/.c: Moved lwip_gethostbyname from sockets.c
1306 to the new file netdb.c; included lwip_getaddrinfo.
1308 2007-11-21 Simon Goldschmidt
1309 * tcp.h, opt.h, tcp.c, tcp_in.c: implemented calculating the effective send-mss
1310 based on the MTU of the netif used to send. Enabled by default. Disable by
1311 setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21492.
1313 2007-11-19 Frédéric Bernon
1314 * api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name
1315 received match the name query), implement DNS_USES_STATIC_BUF (the place where
1316 copy dns payload to parse the response), return an error if there is no place
1317 for a new query, and fix some minor problems.
1319 2007-11-16 Simon Goldschmidt
1320 * new files: ipv4/inet.c, ipv4/inet_chksum.c, ipv6/inet6.c
1321 removed files: core/inet.c, core/inet6.c
1322 Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into
1323 inet and chksum part; changed includes in all lwIP files as appropriate
1325 2007-11-16 Simon Goldschmidt
1326 * api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential
1327 dns resolver function for netconn api (netconn_gethostbyname) and socket api
1328 (gethostbyname/gethostbyname_r).
1330 2007-11-15 Jim Pettinato, Frédéric Bernon
1331 * opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name
1332 requests with RAW api interface. Initialization is done in lwip_init() with
1333 build time options. DNS timer is added in tcpip_thread context. DHCP can set
1334 DNS server ip addresses when options are received. You need to set LWIP_DNS=1
1335 in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get
1336 some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo"
1337 list with points to improve.
1339 2007-11-06 Simon Goldschmidt
1340 * opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly
1341 enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status
1342 for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.
1344 2007-11-06 Simon Goldschmidt
1345 * api.h, api_msg.h and dependent files: Task #7410: Removed the need to include
1346 core header files in api.h (ip/tcp/udp/raw.h) to hide the internal
1347 implementation from netconn api applications.
1349 2007-11-03 Frédéric Bernon
1350 * api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP &
1351 RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled
1352 by default). Netconn API users can use the netconn_recv_bufsize macro to access
1353 it. This is a first release which have to be improve for TCP. Note it used the
1354 netconn::recv_avail which need to be more "thread-safe" (note there is already
1355 the problem for FIONREAD with lwip_ioctl/ioctlsocket).
1357 2007-11-01 Frédéric Bernon, Marc Chaland
1358 * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c:
1359 Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api
1360 layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api
1361 layer. This option enable to delayed TCP PUSH flag on multiple "write" calls.
1362 Note that previous "copy" parameter for "write" APIs is now called "apiflags".
1364 2007-10-24 Frédéric Bernon
1365 * api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than
1366 TCP_EVENT_xxx macros to get a code more readable. It could also help to remove
1367 some code (like we have talk in "patch #5919 : Create compile switch to remove
1368 select code"), but it could be done later.
1370 2007-10-08 Simon Goldschmidt
1371 * many files: Changed initialization: many init functions are not needed any
1372 more since we now rely on the compiler initializing global and static
1375 2007-10-06 Simon Goldschmidt
1376 * ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY
1377 to enqueue the received pbufs so that multiple packets can be reassembled
1378 simultaneously and no static reassembly buffer is needed.
1380 2007-10-05 Simon Goldschmidt
1381 * tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so
1382 all netifs (or ports) can use it.
1384 2007-10-05 Frédéric Bernon
1385 * netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the
1386 common function to reduce a little bit the footprint (for all functions using
1387 only the "netif" parameter).
1389 2007-10-03 Frédéric Bernon
1390 * netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down,
1391 netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce
1392 a little bit the footprint (for all functions using only the "netif" parameter).
1394 2007-09-15 Frédéric Bernon
1395 * udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF
1396 option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for
1397 netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for
1398 IP_MULTICAST_TTL and IP_MULTICAST_IF.
1400 2007-09-10 Frédéric Bernon
1401 * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles
1402 even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime()
1403 each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can
1404 decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but
1405 call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime()
1406 or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
1407 This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
1408 snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
1409 when it's queried (any direct call to "sysuptime" is changed by a call to
1410 snmp_get_sysuptime).
1412 2007-09-09 Frédéric Bernon, Bill Florac
1413 * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP,
1414 and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags
1415 if you want IGMP on an interface. igmp_stop() is now called inside netif_remove().
1416 igmp_report_groups() is now called inside netif_set_link_up() (need to have
1417 LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait
1418 the next query message to receive the matching multicast streams).
1420 2007-09-08 Frédéric Bernon
1421 * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains
1422 IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change).
1423 Use this new field to access to common pcb fields (ttl, tos, so_options, etc...).
1424 Enable to access to these fields with LWIP_TCP=0.
1426 2007-09-05 Frédéric Bernon
1427 * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h,
1428 ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option
1429 LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default).
1430 Be careful, disabling ICMP make your product non-compliant to RFC1122, but
1431 help to reduce footprint, and to reduce "visibility" on the Internet.
1433 2007-09-05 Frédéric Bernon, Bill Florac
1434 * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list
1435 for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new
1436 parameters have to be provided: a task name, and a task stack size. For this
1437 one, since it's platform dependant, you could define the best one for you in
1438 your lwipopts.h. For port maintainers, you can just add these new parameters
1439 in your sys_arch.c file, and but it's not mandatory, use them in your OS
1442 2007-09-05 Frédéric Bernon
1443 * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings
1444 inside init.c for task #7142 "Sanity check user-configurable values".
1446 2007-09-04 Frédéric Bernon, Bill Florac
1447 * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by
1448 memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the
1449 value). It will avoid potential fragmentation problems, use a counter to know
1450 how many times a group is used on an netif, and free it when all applications
1451 leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity
1452 check if LWIP_IGMP!=0).
1454 2007-09-03 Frédéric Bernon
1455 * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement".
1456 Initialize igmp_mac_filter to NULL in netif_add (this field should be set in
1457 the netif's "init" function). Use the "imr_interface" field (for socket layer)
1458 and/or the "interface" field (for netconn layer), for join/leave operations.
1459 The igmp_join/leavegroup first parameter change from a netif to an ipaddr.
1460 This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany).
1462 2007-08-30 Frédéric Bernon
1463 * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions
1464 from api/api_lib". Now netbuf API is independant of netconn, and can be used
1465 with other API (application based on raw API, or future "socket2" API). Ports
1466 maintainers just have to add src/api/netbuf.c in their makefile/projects.
1468 2007-08-30 Frédéric Bernon, Jonathan Larmour
1469 * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check
1470 user-configurable values".
1472 2007-08-29 Frédéric Bernon
1473 * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start.
1474 igmp_start is call inside netif_add. Now, igmp initialization is in the same
1475 spirit than the others modules. Modify some IGMP debug traces.
1477 2007-08-29 Frédéric Bernon
1478 * Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function"
1479 Add lwip_init function to regroup all modules initializations, and to provide
1480 a place to add code for task #7142 "Sanity check user-configurable values".
1481 Ports maintainers should remove direct initializations calls from their code,
1482 and add init.c in their makefiles. Note that lwip_init() function is called
1483 inside tcpip_init, but can also be used by raw api users since all calls are
1484 disabled when matching options are disabled. Also note that their is new options
1485 in opt.h, you should configure in your lwipopts.h (they are enabled per default).
1487 2007-08-26 Marc Boucher
1488 * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL
1489 since they can under certain circumstances be called with an invalid conn
1490 pointer after the connection has been closed (and conn has been freed).
1492 2007-08-25 Frédéric Bernon (Artem Migaev's Patch)
1493 * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up".
1494 Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set.
1496 2007-08-22 Frédéric Bernon
1497 * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK
1498 to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release.
1500 2007-08-22 Frédéric Bernon
1501 * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT &
1502 ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the
1503 name is tcpip_input (we keep the name of 1.2.0 function).
1505 2007-08-17 Jared Grubb
1506 * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool
1507 settings into new memp_std.h and optional user file lwippools.h. This adds
1508 more dynamic mempools, and allows the user to create an arbitrary number of
1509 mempools for mem_malloc.
1511 2007-08-16 Marc Boucher
1512 * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function;
1513 otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely
1514 close the connection.
1516 2007-08-16 Marc Boucher
1517 * sockets.c: lwip_accept(): check netconn_peer() error return.
1519 2007-08-16 Marc Boucher
1520 * mem.c, mem.h: Added mem_calloc().
1522 2007-08-16 Marc Boucher
1523 * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT)
1524 for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG
1525 and starving other message types.
1526 Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API
1528 2007-08-16 Marc Boucher
1529 * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf
1530 type and flgs (later renamed to flags).
1531 Use enum pbuf_flag as pbuf_type. Renumber PBUF_FLAG_*.
1532 Improved lwip_recvfrom(). TCP push now propagated.
1534 2007-08-16 Marc Boucher
1535 * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global
1538 2007-08-16 Marc Boucher
1539 * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h,
1540 etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c:
1541 Added PPPoE support and various PPP improvements.
1543 2007-07-25 Simon Goldschmidt
1544 * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial,
1545 making netbuf_copy_partial use this function.
1547 2007-07-25 Simon Goldschmidt
1548 * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with
1549 2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and
1552 2007-07-13 Jared Grubb (integrated by Frédéric Bernon)
1553 * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add
1554 a link callback in the netif struct, and functions to handle it. Be carefull
1555 for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c)
1556 if you want to be sure to be compatible with future changes...
1558 2007-06-30 Frédéric Bernon
1559 * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.
1561 2007-06-21 Simon Goldschmidt
1562 * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both
1563 LWIP_AUTOIP =0 and =1 to remove redundant code.
1565 2007-06-21 Simon Goldschmidt
1566 * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option
1567 MEM_USE_POOLS to use 4 pools with different sized elements instead of a
1568 heap. This both prevents memory fragmentation and gives a higher speed
1569 at the cost of more memory consumption. Turned off by default.
1571 2007-06-21 Simon Goldschmidt
1572 * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of
1573 netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into
1574 int to be able to send a bigger buffer than 64K with one time (mainly
1575 used from lwip_send).
1577 2007-06-21 Simon Goldschmidt
1578 * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write
1579 into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too.
1581 2007-06-21 Simon Goldschmidt
1582 * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in
1583 netconn_write from api_lib.c to api_msg.c to also prevent multiple context-
1584 changes on low memory or empty send-buffer.
1586 2007-06-18 Simon Goldschmidt
1587 * etharp.c, etharp.h: Changed etharp to use a defined hardware address length
1588 of 6 to avoid loading netif->hwaddr_len every time (since this file is only
1589 used for ethernet and struct eth_addr already had a defined length of 6).
1591 2007-06-17 Simon Goldschmidt
1592 * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets
1593 to disable UDP checksum generation on transmit.
1595 2007-06-13 Frédéric Bernon, Simon Goldschmidt
1596 * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid
1597 pointers or parameters, and let the possibility to redefined it in cc.h. Use
1598 this macro to check "conn" parameter in api_msg.c functions.
1600 2007-06-11 Simon Goldschmidt
1601 * sockets.c, sockets.h: Added UDP lite support for sockets
1603 2007-06-10 Simon Goldschmidt
1604 * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled
1605 by default) to switch off UDP-Lite support if not needed (reduces udp.c code
1608 2007-06-09 Dominik Spies (integrated by Frédéric Bernon)
1609 * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h:
1610 AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and
1611 LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt
1612 (see TODO mark in the source code).
1614 2007-06-09 Simon Goldschmidt
1615 * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for
1616 etharp_output() to match netif->output so etharp_output() can be used
1617 directly as netif->output to save one function call.
1619 2007-06-08 Simon Goldschmidt
1620 * netif.h, ethernetif.c, slipif.c, loopif.c: Added define
1621 NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables,
1622 added initialization of those to ethernetif, slipif and loopif.
1624 2007-05-18 Simon Goldschmidt
1625 * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF
1626 (defaulting to off for now) that can be set to 0 to send fragmented
1627 packets by passing PBUF_REFs down the stack.
1629 2007-05-23 Frédéric Bernon
1630 * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP
1631 connections, such present in patch #5959.
1633 2007-05-23 Frédéric Bernon
1634 * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx
1635 code in only one part...
1637 2007-05-18 Simon Goldschmidt
1638 * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp
1639 elements to overflow. This is achieved by adding some bytes before and after
1640 each pool element (increasing their size, of course), filling them with a
1641 prominent value and checking them on freeing the element.
1642 Set it to 2 to also check every element in every pool each time memp_malloc()
1643 or memp_free() is called (slower but more helpful).
1645 2007-05-10 Simon Goldschmidt
1646 * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for
1647 PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce
1650 2007-05-11 Frédéric Bernon
1651 * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c:
1652 Include a function pointer instead of a table index in the message to reduce
1653 footprint. Disable some part of lwip_send and lwip_sendto if some options are
1654 not set (LWIP_TCP, LWIP_UDP, LWIP_RAW).
1656 2007-05-10 Simon Goldschmidt
1657 * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus
1658 \ extern "C" {' in all header files. Now you can write your application using
1659 the lwIP stack in C++ and simply #include the core files. Note I have left
1660 out the netif/ppp/*h header files for now, since I don't know which files are
1661 included by applications and which are for internal use only.
1663 2007-05-09 Simon Goldschmidt
1664 * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library
1665 memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for
1666 situations where some compilers might inline the copy and save a function
1667 call. Also replaced all calls to memcpy() with calls to (S)MEMCPY().
1669 2007-05-08 Simon Goldschmidt
1670 * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc())
1671 to be overriden in case the C-library malloc implementation is not protected
1672 against concurrent access.
1674 2007-05-04 Simon Goldschmidt (Atte Kojo)
1675 * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending
1676 multiple packets to the same host.
1678 2007-05-04 Frédéric Bernon, Jonathan Larmour
1679 * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible
1680 to corrupt remote addr/port connection state". Reduce problems "not enought memory" with
1681 netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between
1682 sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function.
1683 Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct,
1684 these fields are now renamed "addr" & "port".
1686 2007-04-11 Jonathan Larmour
1687 * sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new
1688 sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return
1689 with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro
1690 by the port in sys_arch.h if desired.
1692 2007-04-06 Frédéric Bernon, Simon Goldschmidt
1693 * opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API
1694 allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp
1695 clients, using new functions from netifapi.h. Disable as default (no port change to do).
1697 2007-04-05 Frédéric Bernon
1698 * sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant.
1700 2007-04-04 Simon Goldschmidt
1701 * arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x)
1702 use this for and architecture-independent form to tell the compiler you intentionally
1703 are not using this variable. Can be overriden in cc.h.
1705 2007-03-28 Frédéric Bernon
1706 * opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to
1707 define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded
1708 string, point on one of your's ethernetif field, or alloc a string you will free yourself).
1709 It will be used by DHCP to register a client hostname, but can also be use when you call
1712 2007-03-28 Frédéric Bernon
1713 * netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to
1714 initialize a network interface's flag with. It tell this interface is an ethernet
1715 device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility
1716 Support for IPv4" section 4.6) when interface is "up" with netif_set_up().
1718 2007-03-26 Frédéric Bernon, Jonathan Larmour
1719 * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build
1720 time if you only use PPP or SLIP. The default is enable. Note we don't have to call
1721 etharp_init in your port's initilization sequence if you use tcpip.c, because this call
1722 is done in tcpip_init function.
1724 2007-03-22 Frédéric Bernon
1725 * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the
1726 new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in
1727 your lwipopts.h. More, unused counters are not defined in the stats structs, and not
1728 display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined
1729 but never used. Fix msg_in.c with the correct #if test for a stat display.
1731 2007-03-21 Kieran Mansley
1732 * netif.c, netif.h: Apply patch#4197 with some changes (originator: rireland@hmgsl.com).
1733 Provides callback on netif up/down state change.
1735 2007-03-11 Frédéric Bernon, Mace Gael, Steve Reynolds
1736 * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, igmp.h, igmp.c,
1737 ip.c, netif.h, tcpip.c, opt.h:
1738 New configuration option LWIP_IGMP to enable IGMP processing. Based on only one
1739 filter per all network interfaces. Declare a new function in netif to enable to
1740 control the MAC filter (to reduce lwIP traffic processing).
1742 2007-03-11 Frédéric Bernon
1743 * tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can
1744 be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this
1745 unless you know what you're doing (default are RFC1122 compliant). Note
1746 that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds.
1748 2007-03-08 Frédéric Bernon
1749 * tcp.h: Keepalive values can be configured at compile time, but don't change
1750 this unless you know what you're doing (default are RFC1122 compliant).
1752 2007-03-08 Frédéric Bernon
1753 * sockets.c, api.h, api_lib.c, tcpip.c, sys.h, sys.c, err.c, opt.h:
1754 Implement LWIP_SO_RCVTIMEO configuration option to enable/disable SO_RCVTIMEO
1755 on UDP sockets/netconn.
1757 2007-03-08 Simon Goldschmidt
1758 * snmp_msg.h, msg_in.c: SNMP UDP ports can be configured at compile time.
1760 2007-03-06 Frédéric Bernon
1761 * api.h, api_lib.c, sockets.h, sockets.c, tcpip.c, sys.h, sys.c, err.h:
1762 Implement SO_RCVTIMEO on UDP sockets/netconn.
1764 2007-02-28 Kieran Mansley (based on patch from Simon Goldschmidt)
1765 * api_lib.c, tcpip.c, memp.c, memp.h: make API msg structs allocated
1766 on the stack and remove the API msg type from memp
1768 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
1769 * sockets.h, sockets.c: Move socket initialization to new
1770 lwip_socket_init() function.
1771 NOTE: this changes the API with ports. Ports will have to be
1772 updated to call lwip_socket_init() now.
1774 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
1775 * api_lib.c: Use memcpy in netbuf_copy_partial.
1780 2008-03-17 Frédéric Bernon, Ed Kerekes
1781 * igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have
1782 some problems to fill the IP header on some targets, use now the
1783 ip.h macros to do it).
1785 2008-03-13 Frédéric Bernon
1786 * sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using
1787 (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a
1788 TCP connection caused a crash. Note that using (lwip_)recvfrom
1789 like this is a bit slow and that using (lwip)getpeername is the
1790 good lwip way to do it (so, using recv is faster on tcp sockets).
1792 2008-03-12 Frédéric Bernon, Jonathan Larmour
1793 * api_msg.c, contrib/apps/ping.c: Fix bug #22530 "api_msg.c's
1794 recv_raw() does not consume data", and the ping sample (with
1795 LWIP_SOCKET=1, the code did the wrong supposition that lwip_recvfrom
1796 returned the IP payload, without the IP header).
1798 2008-03-04 Jonathan Larmour
1799 * mem.c, stats.c, mem.h: apply patch #6414 to avoid compiler errors
1800 and/or warnings on some systems where mem_size_t and size_t differ.
1801 * pbuf.c, ppp.c: Fix warnings on some systems with mem_malloc.
1803 2008-03-04 Kieran Mansley (contributions by others)
1804 * Numerous small compiler error/warning fixes from contributions to
1805 mailing list after 1.3.0 release candidate made.
1807 2008-01-25 Cui hengbin (integrated by Frédéric Bernon)
1808 * dns.c: Fix bug #22108 "DNS problem" caused by unaligned structures.
1810 2008-01-15 Kieran Mansley
1811 * tcp_out.c: BUG20511. Modify persist timer to start when we are
1812 prevented from sending by a small send window, not just a zero
1815 2008-01-09 Jonathan Larmour
1816 * opt.h, ip.c: Rename IP_OPTIONS define to IP_OPTIONS_ALLOWED to avoid
1817 conflict with Linux system headers.
1819 2008-01-06 Jonathan Larmour
1820 * dhcp.c: fix bug #19927: "DHCP NACK problem" by clearing any existing set IP
1821 address entirely on receiving a DHCPNAK, and restarting discovery.
1823 2007-12-21 Simon Goldschmidt
1824 * sys.h, api_lib.c, api_msg.c, sockets.c: fix bug #21698: "netconn->recv_avail
1825 is not protected" by using new macros for interlocked access to modify/test
1826 netconn->recv_avail.
1828 2007-12-20 Kieran Mansley (based on patch from Oleg Tyshev)
1829 * tcp_in.c: fix bug# 21535 (nrtx not reset correctly in SYN_SENT state)
1831 2007-12-20 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
1832 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: fix bug #20199 (better handling
1833 of silly window avoidance and prevent lwIP from shrinking the window)
1835 2007-12-04 Simon Goldschmidt
1836 * tcp.c, tcp_in.c: fix bug #21699 (segment leak in ooseq processing when last
1837 data packet was lost): add assert that all segment lists are empty in
1838 tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED
1839 state from LAST_ACK in tcp_process
1841 2007-12-02 Simon Goldschmidt
1842 * sockets.h: fix bug #21654: exclude definition of struct timeval from #ifndef FD_SET
1843 If including <sys/time.h> for system-struct timeval, LWIP_TIMEVAL_PRIVATE now
1844 has to be set to 0 in lwipopts.h
1846 2007-12-02 Simon Goldschmidt
1847 * api_msg.c, api_lib.c: fix bug #21656 (recvmbox problem in netconn API): always
1848 allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen
1849 netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox.
1850 This is a fix for thread-safety and allocates all items needed for a netconn
1851 when the netconn is created.
1853 2007-11-30 Simon Goldschmidt
1854 * udp.c: first attempt to fix bug #21655 (DHCP doesn't work reliably with multiple
1855 netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed
1856 to netif->dhcp->pcb only (if that exists) and not to any other pcb for the same
1857 port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address)
1859 2007-11-27 Simon Goldschmidt
1860 * ip.c: fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by
1861 letting ip_route only use netifs that are up.
1863 2007-11-27 Simon Goldschmidt
1864 * err.h, api_lib.c, api_msg.c, sockets.c: Changed error handling: ERR_MEM, ERR_BUF
1865 and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and
1866 sockets block most operations once they have seen a fatal error.
1868 2007-11-27 Simon Goldschmidt
1869 * udp.h, udp.c, dhcp.c: Implemented new function udp_sendto_if which takes the
1870 netif to send as an argument (to be able to send on netifs that are down).
1872 2007-11-26 Simon Goldschmidt
1873 * tcp_in.c: Fixed bug #21582: pcb->acked accounting can be wrong when ACKs
1876 2007-11-21 Simon Goldschmidt
1877 * tcp.h, tcp_out.c, api_msg.c: Fixed bug #20287: tcp_output_nagle sends too early
1878 Fixed the nagle algorithm; nagle now also works for all raw API applications
1879 and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY'
1881 2007-11-12 Frédéric Bernon
1882 * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most
1883 of the netconn_peer and netconn_addr processing is done inside tcpip_thread
1884 context in do_getaddr.
1886 2007-11-10 Simon Goldschmidt
1887 * etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can
1888 happen any time). Now the packet simply isn't enqueued when out of memory.
1890 2007-11-01 Simon Goldschmidt
1891 * tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or
1892 TCP_MSS if that is smaller) as long as no MSS option is received from the
1895 2007-11-01 Simon Goldschmidt
1896 * tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN)
1897 is now based on TCP_MSS instead of pcb->mss (on passive open now effectively
1898 sending our configured TCP_MSS instead of the one received).
1900 2007-11-01 Simon Goldschmidt
1901 * tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was
1902 calculated based on the configured TCP_MSS, not on the MSS option received
1905 2007-10-09 Simon Goldschmidt
1906 * udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too
1907 short and also was generated wrong if checksum coverage != tot_len;
1908 receive: checksum was calculated wrong if checksum coverage != tot_len
1910 2007-10-08 Simon Goldschmidt
1911 * mem.c: lfree was not updated in mem_realloc!
1913 2007-10-07 Frédéric Bernon
1914 * sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential
1915 crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT:
1916 this change cause an API breakage for netconn_addr, since a parameter
1917 type change. Any compiler should cause an error without any changes in
1918 yours netconn_peer calls (so, it can't be a "silent change"). It also
1919 reduce a little bit the footprint for socket layer (lwip_getpeername &
1920 lwip_getsockname use now a common lwip_getaddrname function since
1921 netconn_peer & netconn_addr have the same parameters).
1923 2007-09-20 Simon Goldschmidt
1924 * tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state)
1925 by checking tcp_tw_pcbs also
1927 2007-09-19 Simon Goldschmidt
1928 * icmp.c: Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies)
1930 2007-09-15 Mike Kleshov
1931 * mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used)
1933 2007-09-06 Frédéric Bernon
1934 * several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove
1935 it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which
1936 already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h"
1937 if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h.
1939 2007-08-30 Frédéric Bernon
1940 * igmp.h, igmp.c: Some changes to remove some redundant code, add some traces,
1941 and fix some coding style.
1943 2007-08-28 Frédéric Bernon
1944 * tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any
1945 kind of packets. These packets are considered like Ethernet packets (payload
1946 pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets
1947 are considered like IP packets (payload pointing to iphdr).
1949 2007-08-27 Frédéric Bernon
1950 * api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error
1951 problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state
1952 and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT).
1954 2007-08-24 Kieran Mansley
1955 * inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy
1956 compiler (Paradigm C++)
1958 2007-08-09 Frédéric Bernon, Bill Florac
1959 * stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement.
1960 Introduce IGMP_STATS to centralize statistics management.
1962 2007-08-09 Frédéric Bernon, Bill Florac
1963 * udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast
1964 packet on a udp pcb binded on an netif's IP address, and not on "any".
1966 2007-08-09 Frédéric Bernon, Bill Florac
1967 * igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement.
1968 This is mainly on using lookup/lookfor, and some coding styles...
1970 2007-07-26 Frédéric Bernon (and "thedoctor")
1971 * igmp.c: Fix bug #20595 to accept IGMPv3 "Query" messages.
1973 2007-07-25 Simon Goldschmidt
1974 * api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if
1975 tcp_output fails in tcp_close, the code in do_close_internal gets simpler
1976 (tcp_output is called again later from tcp timers).
1978 2007-07-25 Simon Goldschmidt
1979 * ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old
1980 copy_from_pbuf, which illegally modified the given pbuf.
1982 2007-07-25 Simon Goldschmidt
1983 * tcp_out.c: tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs:
1984 changed snd_queuelen++ to snd_queuelen += pbuf_clen(p).
1986 2007-07-24 Simon Goldschmidt
1987 * api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the
1988 correct state (must be CLOSED).
1990 2007-07-13 Thomas Taranowski (commited by Jared Grubb)
1991 * memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed
1992 allocation. It now returns NULL.
1994 2007-07-13 Frédéric Bernon
1995 * api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in
1998 2007-07-13 Frédéric Bernon
1999 * api_msg.c: Fix bug #20315: possible memory leak problem if tcp_listen failed,
2000 because current code doesn't follow rawapi.txt documentation.
2002 2007-07-13 Kieran Mansley
2003 * src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in
2004 out of sequence processing of received packets
2006 2007-07-03 Simon Goldschmidt
2007 * nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an
2008 assumption is made that this pbuf is in one piece (i.e. not chained). These
2009 assumptions clash with the possibility of converting to fully pool-based
2010 pbuf implementations, where PBUF_RAM pbufs might be chained.
2012 2007-07-03 Simon Goldschmidt
2013 * api.h, api_lib.c, api_msg.c: Final fix for bug #20021 and some other problems
2014 when closing tcp netconns: removed conn->sem, less context switches when
2015 closing, both netconn_close and netconn_delete should safely close tcp
2018 2007-07-02 Simon Goldschmidt
2019 * ipv4/ip.h, ipv6/ip.h, opt.h, netif.h, etharp.h, ipv4/ip.c, netif.c, raw.c,
2020 tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off)
2021 to cache ARP table indices with each pcb instead of single-entry cache for
2024 2007-07-02 Simon Goldschmidt
2025 * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent
2026 warnings when assigning to smaller types.
2028 2007-06-28 Simon Goldschmidt
2029 * tcp_out.c: Added check to prevent tcp_pcb->snd_queuelen from overflowing.
2031 2007-06-28 Simon Goldschmidt
2032 * tcp.h: Fixed bug #20287: Fixed nagle algorithm (sending was done too early if
2033 a segment contained chained pbufs)
2035 2007-06-28 Frédéric Bernon
2036 * autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute
2037 a "pseudo-random" value based on netif's MAC and some autoip fields. It's always
2038 possible to define this macro in your own lwipopts.h to always use C library's
2039 rand(). Note that autoip_create_rand_addr doesn't use this macro.
2041 2007-06-28 Frédéric Bernon
2042 * netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option
2043 LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications
2044 in api_lib/api_msg (use pointers and not type with table, etc...)
2046 2007-06-26 Simon Goldschmidt
2047 * udp.h: Fixed bug #20259: struct udp_hdr was lacking the packin defines.
2049 2007-06-25 Simon Goldschmidt
2050 * udp.c: Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload
2051 for udp packets with no matching pcb.
2053 2007-06-25 Simon Goldschmidt
2054 * udp.c: Fixed bug #20220: UDP PCB search in udp_input(): a non-local match
2055 could get udp input packets if the remote side matched.
2057 2007-06-13 Simon Goldschmidt
2058 * netif.c: Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get
2059 changed in netif_set_ipaddr if previous netif->ip_addr.addr was 0.
2061 2007-06-13 Simon Goldschmidt
2062 * api_msg.c: pcb_new sets conn->err if protocol is not implemented
2063 -> netconn_new_..() does not allocate a new connection for unsupported
2066 2007-06-13 Frédéric Bernon, Simon Goldschmidt
2067 * api_lib.c: change return expression in netconn_addr and netconn_peer, because
2068 conn->err was reset to ERR_OK without any reasons (and error was lost)...
2070 2007-06-13 Frédéric Bernon, Matthias Weisser
2071 * opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename
2072 MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid
2073 some macro names collision with some OS macros.
2075 2007-06-11 Simon Goldschmidt
2076 * udp.c: UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0,
2077 create checksum over the complete packet. On RX, if it's < 8 (and not 0),
2078 discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both
2081 2007-06-11 Srinivas Gollakota & Oleg Tyshev
2082 * tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP flags"
2083 where TCP flags wasn't initialized in tcp_keepalive.
2085 2007-06-03 Simon Goldschmidt
2086 * udp.c: udp_input(): Input pbuf was not freed if pcb had no recv function
2087 registered, p->payload was modified without modifying p->len if sending
2088 icmp_dest_unreach() (had no negative effect but was definitively wrong).
2090 2007-06-03 Simon Goldschmidt
2091 * icmp.c: Corrected bug #19937: For responding to an icmp echo request, icmp
2092 re-used the input pbuf even if that didn't have enough space to include the
2093 link headers. Now the space is tested and a new pbuf is allocated for the
2094 echo response packet if the echo request pbuf isn't big enough.
2096 2007-06-01 Simon Goldschmidt
2097 * sockets.c: Checked in patch #5914: Moved sockopt processing into tcpip_thread.
2099 2007-05-23 Frédéric Bernon
2100 * api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only
2101 allocated by do_listen if success) and netconn_accept errors handling. In
2102 most of api_lib functions, we replace some errors checkings like "if (conn==NULL)"
2103 by ASSERT, except for netconn_delete.
2105 2007-05-23 Frédéric Bernon
2106 * api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return
2107 an error code if it's impossible to fetch a pbuf on a TCP connection (and not
2108 directly close the recvmbox).
2110 2007-05-22 Simon Goldschmidt
2111 * tcp.c: Fixed bug #1895 (tcp_bind not correct) by introducing a list of
2112 bound but unconnected (and non-listening) tcp_pcbs.
2114 2007-05-22 Frédéric Bernon
2115 * sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only
2116 used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of
2117 sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features
2118 like "sys_timeout" in their application threads.
2120 2007-05-22 Frédéric Bernon
2121 * api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see
2122 which parameters are used by which do_xxx function, and to avoid "misusing"
2123 parameters (patch #5938).
2125 2007-05-22 Simon Goldschmidt
2126 * api_lib.c, api_msg.c, raw.c, api.h, api_msg.h, raw.h: Included patch #5938:
2127 changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto
2128 is only 8 bits wide. This affects the api, as there, the protocol was
2131 2007-05-18 Simon Goldschmidt
2132 * memp.c: addition to patch #5913: smaller pointer was returned but
2133 memp_memory was the same size -> did not save memory.
2135 2007-05-16 Simon Goldschmidt
2136 * loopif.c, slipif.c: Fix bug #19729: free pbuf if netif->input() returns
2139 2007-05-16 Simon Goldschmidt
2140 * api_msg.c, udp.c: If a udp_pcb has a local_ip set, check if it is the same
2141 as the one of the netif used for sending to prevent sending from old
2142 addresses after a netif address gets changed (partly fixes bug #3168).
2144 2007-05-16 Frédéric Bernon
2145 * tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work
2146 with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in
2147 tcpip_init) because we have to be sure that network interfaces are already
2148 added (mac filter is updated only in igmp_init for the moment).
2150 2007-05-16 Simon Goldschmidt
2151 * mem.c, memp.c: Removed semaphores from memp, changed sys_sem_wait calls
2152 into sys_arch_sem_wait calls to prevent timers from running while waiting
2153 for the heap. This fixes bug #19167.
2155 2007-05-13 Simon Goldschmidt
2156 * tcp.h, sockets.h, sockets.c: Fixed bug from patch #5865 by moving the defines
2157 for socket options (lwip_set/-getsockopt) used with level IPPROTO_TCP from
2160 2007-05-07 Simon Goldschmidt
2161 * mem.c: Another attempt to fix bug #17922.
2163 2007-05-04 Simon Goldschmidt
2164 * pbuf.c, pbuf.h, etharp.c: Further update to ARP queueing: Changed pbuf_copy()
2165 implementation so that it can be reused (don't allocate the target
2166 pbuf inside pbuf_copy()).
2168 2007-05-04 Simon Goldschmidt
2169 * memp.c: checked in patch #5913: in memp_malloc() we can return memp as mem
2170 to save a little RAM (next pointer of memp is not used while not in pool).
2173 * sockets.c: Fix ioctl FIONREAD when some data remains from last recv.
2176 2007-04-23 Simon Goldschmidt
2177 * loopif.c, loopif.h, opt.h, src/netif/FILES: fix bug #2595: "loopif results
2178 in NULL reference for incoming TCP packets". Loopif has to be configured
2179 (using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input()
2180 (multithreading environments, e.g. netif->input() = tcpip_input()) or
2181 putting packets on a list that is fed to the stack by calling loopif_poll()
2182 (single-thread / NO_SYS / polling environment where e.g.
2183 netif->input() = ip_input).
2185 2007-04-17 Jonathan Larmour
2186 * pbuf.c: Use s32_t in pbuf_realloc(), as an s16_t can't reliably hold
2187 the difference between two u16_t's.
2188 * sockets.h: FD_SETSIZE needs to match number of sockets, which is
2189 MEMP_NUM_NETCONN in sockets.c right now.
2191 2007-04-12 Jonathan Larmour
2192 * icmp.c: Reset IP header TTL in ICMP ECHO responses (bug #19580).
2194 2007-04-12 Kieran Mansley
2195 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Modify way the retransmission
2196 timer is reset to fix bug#19434, with help from Oleg Tyshev.
2198 2007-04-11 Simon Goldschmidt
2199 * etharp.c, pbuf.c, pbuf.h: 3rd fix for bug #11400 (arp-queuing): More pbufs than
2200 previously thought need to be copied (everything but PBUF_ROM!). Cleaned up
2201 pbuf.c: removed functions no needed any more (by etharp).
2203 2007-04-11 Kieran Mansley
2204 * inet.c, ip_addr.h, sockets.h, sys.h, tcp.h: Apply patch #5745: Fix
2205 "Constant is long" warnings with 16bit compilers. Contributed by
2206 avatar@mmlab.cse.yzu.edu.tw
2208 2007-04-05 Frédéric Bernon, Jonathan Larmour
2209 * api_msg.c: Fix bug #16830: "err_tcp() posts to connection mailbox when no pend on
2210 the mailbox is active". Now, the post is only done during a connect, and do_send,
2211 do_write and do_join_leave_group don't do anything if a previous error was signaled.
2213 2007-04-03 Frédéric Bernon
2214 * ip.c: Don't set the IP_DF ("Don't fragment") flag in the IP header in IP output
2215 packets. See patch #5834.
2217 2007-03-30 Frédéric Bernon
2218 * api_msg.c: add a "pcb_new" helper function to avoid redundant code, and to add
2219 missing pcb allocations checking (in do_bind, and for each raw_new). Fix style.
2221 2007-03-30 Frédéric Bernon
2222 * most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with
2223 others environment defines (these were too "generic").
2225 2007-03-28 Frédéric Bernon
2226 * api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal pbuf_alloc call
2227 result and can cause a crash. lwip_send now check netbuf_ref result.
2229 2007-03-28 Simon Goldschmidt
2230 * sockets.c Remove "#include <errno.h>" from sockets.c to avoid multiple
2231 definition of macros (in errno.h and lwip/arch.h) if LWIP_PROVIDE_ERRNO is
2232 defined. This is the way it should have been already (looking at
2235 2007-03-28 Kieran Mansley
2236 * opt.h Change default PBUF_POOL_BUFSIZE (again) to accomodate default MSS +
2237 IP and TCP headers *and* physical link headers
2239 2007-03-26 Frédéric Bernon (based on patch from Dmitry Potapov)
2240 * api_lib.c: patch for netconn_write(), fixes a possible race condition which cause
2241 to send some garbage. It is not a definitive solution, but the patch does solve
2242 the problem for most cases.
2244 2007-03-22 Frédéric Bernon
2245 * api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used).
2247 2007-03-22 Frédéric Bernon
2248 * api_lib.c: somes resources couldn't be freed if there was errors during
2249 netconn_new_with_proto_and_callback.
2251 2007-03-22 Frédéric Bernon
2252 * ethernetif.c: update netif->input calls to check return value. In older ports,
2253 it's a good idea to upgrade them, even if before, there could be another problem
2254 (access to an uninitialized mailbox).
2256 2007-03-21 Simon Goldschmidt
2257 * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed
2258 by casting to unsigned).
2260 2007-03-21 Frédéric Bernon
2261 * api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from
2262 api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a
2263 dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call.
2264 Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a
2265 faster and more reliable communication between api_lib and tcpip.
2267 2007-03-21 Frédéric Bernon
2268 * opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0.
2270 2007-03-21 Frédéric Bernon
2271 * api_msg.c, igmp.c, igmp.h: Fix C++ style comments
2273 2007-03-21 Kieran Mansley
2274 * opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS +
2277 2007-03-21 Kieran Mansley
2278 * Fix all uses of pbuf_header to check the return value. In some
2279 cases just assert if it fails as I'm not sure how to fix them, but
2280 this is no worse than before when they would carry on regardless
2283 2007-03-21 Kieran Mansley
2284 * sockets.c, igmp.c, igmp.h, memp.h: Fix C++ style comments and
2285 comment out missing header include in icmp.c
2287 2007-03-20 Frédéric Bernon
2288 * memp.h, stats.c: Fix stats_display function where memp_names table wasn't
2289 synchronized with memp.h.
2291 2007-03-20 Frédéric Bernon
2292 * tcpip.c: Initialize tcpip's mbox, and verify if initialized in tcpip_input,
2293 tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init problem with
2294 network interfaces. Also fix a compiler warning.
2296 2007-03-20 Kieran Mansley
2297 * udp.c: Only try and use pbuf_header() to make space for headers if
2298 not a ROM or REF pbuf.
2300 2007-03-19 Frédéric Bernon
2301 * api_msg.h, api_msg.c, tcpip.h, tcpip.c: Add return types to tcpip_apimsg()
2304 2007-03-19 Frédéric Bernon
2305 * Remove unimplemented "memp_realloc" function from memp.h.
2307 2007-03-11 Simon Goldschmidt
2308 * pbuf.c: checked in patch #5796: pbuf_alloc: len field claculation caused
2311 2007-03-11 Simon Goldschmidt (based on patch from Dmitry Potapov)
2312 * api_lib.c, sockets.c, api.h, api_msg.h, sockets.h: Fixed bug #19251
2313 (missing `const' qualifier in socket functions), to get more compatible to
2314 standard POSIX sockets.
2316 2007-03-11 Frédéric Bernon (based on patch from Dmitry Potapov)
2317 * sockets.c: Add asserts inside bind, connect and sendto to check input
2318 parameters. Remove excessive set_errno() calls after get_socket(), because
2319 errno is set inside of get_socket(). Move last sock_set_errno() inside
2322 2007-03-09 Simon Goldschmidt
2323 * memp.c: Fixed bug #11400: New etharp queueing introduced bug: memp_memory
2324 was allocated too small.
2326 2007-03-06 Simon Goldschmidt
2327 * tcpip.c: Initialize dhcp timers in tcpip_thread (if LWIP_DHCP) to protect
2328 the stack from concurrent access.
2330 2007-03-06 Frédéric Bernon, Dmitry Potapov
2331 * tcpip.c, ip_frag.c, ethernetif.c: Fix some build problems, and a redundancy
2332 call to "lwip_stats.link.recv++;" in low_level_input() & ethernetif_input().
2334 2007-03-06 Simon Goldschmidt
2335 * ip_frag.c, ip_frag.h: Reduce code size: don't include code in those files
2336 if IP_FRAG == 0 and IP_REASSEMBLY == 0
2338 2007-03-06 Frédéric Bernon, Simon Goldschmidt
2339 * opt.h, ip_frag.h, tcpip.h, tcpip.c, ethernetif.c: add new configuration
2340 option named ETHARP_TCPIP_ETHINPUT, which enable the new tcpip_ethinput.
2341 Allow to do ARP processing for incoming packets inside tcpip_thread
2342 (protecting ARP layer against concurrent access). You can also disable
2343 old code using tcp_input with new define ETHARP_TCPIP_INPUT set to 0.
2344 Older ports have to use tcpip_ethinput.
2346 2007-03-06 Simon Goldschmidt (based on patch from Dmitry Potapov)
2347 * err.h, err.c: fixed compiler warning "initialization dircards qualifiers
2348 from pointer target type"
2350 2007-03-05 Frédéric Bernon
2351 * opt.h, sockets.h: add new configuration options (LWIP_POSIX_SOCKETS_IO_NAMES,
2352 ETHARP_TRUST_IP_MAC, review SO_REUSE)
2354 2007-03-04 Frédéric Bernon
2355 * api_msg.c: Remove some compiler warnings : parameter "pcb" was never
2358 2007-03-04 Frédéric Bernon
2359 * api_lib.c: Fix "[patch #5764] api_lib.c cleanup: after patch #5687" (from
2361 The api_msg struct stay on the stack (not moved to netconn struct).
2363 2007-03-04 Simon Goldschmidt (based on patch from Dmitry Potapov)
2364 * pbuf.c: Fix BUG#19168 - pbuf_free can cause deadlock (if
2365 SYS_LIGHTWEIGHT_PROT=1 & freeing PBUF_RAM when mem_sem is not available)
2366 Also fixed cast warning in pbuf_alloc()
2368 2007-03-04 Simon Goldschmidt
2369 * etharp.c, etharp.h, memp.c, memp.h, opt.h: Fix BUG#11400 - don't corrupt
2370 existing pbuf chain when enqueuing multiple pbufs to a pending ARP request
2372 2007-03-03 Frédéric Bernon
2373 * udp.c: remove obsolete line "static struct udp_pcb *pcb_cache = NULL;"
2374 It is static, and never used in udp.c except udp_init().
2376 2007-03-02 Simon Goldschmidt
2377 * tcpip.c: Moved call to ip_init(), udp_init() and tcp_init() from
2378 tcpip_thread() to tcpip_init(). This way, raw API connections can be
2379 initialized before tcpip_thread is running (e.g. before OS is started)
2381 2007-03-02 Frédéric Bernon
2382 * rawapi.txt: Fix documentation mismatch with etharp.h about etharp_tmr's call
2385 2007-02-28 Kieran Mansley
2386 * pbuf.c: Fix BUG#17645 - ensure pbuf payload pointer is not moved
2387 outside the region of the pbuf by pbuf_header()
2389 2007-02-28 Kieran Mansley
2390 * sockets.c: Fix BUG#19161 - ensure milliseconds timeout is non-zero
2391 when supplied timeout is also non-zero
2395 2006-12-05 Leon Woestenberg
2396 * CHANGELOG: Mention STABLE-1.2.0 release.
2400 2006-12-01 Christiaan Simons
2401 * mem.h, opt.h: Added MEM_LIBC_MALLOC option.
2402 Note this is a workaround. Currently I have no other options left.
2404 2006-10-26 Christiaan Simons (accepted patch by Jonathan Larmour)
2405 * ipv4/ip_frag.c: rename MAX_MTU to IP_FRAG_MAX_MTU and move define
2406 to include/lwip/opt.h.
2407 * ipv4/lwip/ip_frag.h: Remove unused IP_REASS_INTERVAL.
2408 Move IP_REASS_MAXAGE and IP_REASS_BUFSIZE to include/lwip/opt.h.
2409 * opt.h: Add above new options.
2411 2006-08-18 Christiaan Simons
2412 * tcp_{in,out}.c: added SNMP counters.
2413 * ipv4/ip.c: added SNMP counters.
2414 * ipv4/ip_frag.c: added SNMP counters.
2416 2006-08-08 Christiaan Simons
2417 * etharp.{c,h}: added etharp_find_addr() to read
2418 (stable) ethernet/IP address pair from ARP table
2420 2006-07-14 Christiaan Simons
2421 * mib_structs.c: added
2422 * include/lwip/snmp_structs.h: added
2423 * netif.{c,h}, netif/ethernetif.c: added SNMP statistics to netif struct
2425 2006-07-06 Christiaan Simons
2426 * snmp/asn1_{enc,dec}.c added
2428 * snmp/msg_{in,out}.c added
2429 * include/lwip/snmp_asn1.h added
2430 * include/lwip/snmp_msg.h added
2431 * doc/snmp_agent.txt added
2433 2006-03-29 Christiaan Simons
2434 * inet.c, inet.h: Added platform byteswap support.
2435 Added LWIP_PLATFORM_BYTESWAP define (defaults to 0) and
2436 optional LWIP_PLATFORM_HTONS(), LWIP_PLATFORM_HTONL() macros.
2440 2006-11-30 Christiaan Simons
2441 * dhcp.c: Fixed false triggers of request_timeout.
2443 2006-11-28 Christiaan Simons
2444 * netif.c: In netif_add() fixed missing clear of ip_addr, netmask, gw and flags.
2446 2006-10-11 Christiaan Simons
2447 * api_lib.c etharp.c, ip.c, memp.c, stats.c, sys.{c,h} tcp.h:
2448 Partially accepted patch #5449 for ANSI C compatibility / build fixes.
2449 * ipv4/lwip/ip.h ipv6/lwip/ip.h: Corrected UDP-Lite protocol
2450 identifier from 170 to 136 (bug #17574).
2452 2006-10-10 Christiaan Simons
2453 * api_msg.c: Fixed Nagle algorithm as reported by Bob Grice.
2455 2006-08-17 Christiaan Simons
2456 * udp.c: Fixed bug #17200, added check for broadcast
2457 destinations for PCBs bound to a unicast address.
2459 2006-08-07 Christiaan Simons
2460 * api_msg.c: Flushing TCP output in do_close() (bug #15926).
2462 2006-06-27 Christiaan Simons
2463 * api_msg.c: Applied patch for cold case (bug #11135).
2464 In accept_function() ensure newconn->callback is always initialized.
2466 2006-06-15 Christiaan Simons
2467 * mem.h: added MEM_SIZE_F alias to fix an ancient cold case (bug #1748),
2468 facilitate printing of mem_size_t and u16_t statistics.
2470 2006-06-14 Christiaan Simons
2471 * api_msg.c: Applied patch #5146 to handle allocation failures
2472 in accept() by Kevin Lawson.
2474 2006-05-26 Christiaan Simons
2475 * api_lib.c: Removed conn->sem creation and destruction
2476 from netconn_write() and added sys_sem_new to netconn_new_*.
2480 2006-03-03 Christiaan Simons
2481 * ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap
2482 access and added pbuf_alloc() return value checks.
2484 2006-01-01 Leon Woestenberg <leon.woestenberg@gmx.net>
2485 * tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is
2486 now handled by the checksum routine properly.
2488 2006-02-27 Leon Woestenberg <leon.woestenberg@gmx.net>
2489 * pbuf.c: Fix alignment; pbuf_init() would not work unless
2490 pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.)
2492 2005-12-20 Leon Woestenberg <leon.woestenberg@gmx.net>
2493 * tcp.c: Remove PCBs which stay in LAST_ACK state too long. Patch
2494 submitted by Mitrani Hiroshi.
2496 2005-12-15 Christiaan Simons
2497 * inet.c: Disabled the added summing routine to preserve code space.
2499 2005-12-14 Leon Woestenberg <leon.woestenberg@gmx.net>
2500 * tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
2501 Added Curt McDowell's optimized checksumming routine for future
2502 inclusion. Need to create test case for unaliged, aligned, odd,
2503 even length combination of cases on various endianess machines.
2505 2005-12-09 Christiaan Simons
2506 * inet.c: Rewrote standard checksum routine in proper portable C.
2508 2005-11-25 Christiaan Simons
2509 * udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
2510 * *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
2511 u32_t, s32_t typedefs. This solves most debug word-length assumes.
2513 2005-07-17 Leon Woestenberg <leon.woestenberg@gmx.net>
2514 * inet.c: Fixed unaligned 16-bit access in the standard checksum
2515 routine by Peter Jolasson.
2516 * slipif.c: Fixed implementation assumption of single-pbuf datagrams.
2518 2005-02-04 Leon Woestenberg <leon.woestenberg@gmx.net>
2519 * tcp_out.c: Fixed uninitialized 'queue' referenced in memerr branch.
2520 * tcp_{out|in}.c: Applied patch fixing unaligned access.
2522 2005-01-04 Leon Woestenberg <leon.woestenberg@gmx.net>
2523 * pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement.
2525 2005-01-03 Leon Woestenberg <leon.woestenberg@gmx.net>
2526 * udp.c: UDP pcb->recv() was called even when it was NULL.
2530 2004-12-28 Leon Woestenberg <leon.woestenberg@gmx.net>
2531 * etharp.*: Disabled multiple packets on the ARP queue.
2532 This clashes with TCP queueing.
2534 2004-11-28 Leon Woestenberg <leon.woestenberg@gmx.net>
2535 * etharp.*: Fixed race condition from ARP request to ARP timeout.
2536 Halved the ARP period, doubled the period counts.
2537 ETHARP_MAX_PENDING now should be at least 2. This prevents
2538 the counter from reaching 0 right away (which would allow
2539 too little time for ARP responses to be received).
2541 2004-11-25 Leon Woestenberg <leon.woestenberg@gmx.net>
2542 * dhcp.c: Decline messages were not multicast but unicast.
2543 * etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
2544 Do not try hard to insert arbitrary packet's source address,
2545 etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
2546 etharp_query() now always DOES call ETHARP_TRY_HARD so that users
2547 querying an address will see it appear in the cache (DHCP could
2548 suffer from this when a server invalidly gave an in-use address.)
2549 * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
2550 comparing network addresses (identifiers), not the network masks
2552 * ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
2553 IP address actually belongs to the network of the given interface.
2555 2004-11-24 Kieran Mansley <kjm25@cam.ac.uk>
2556 * tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.
2560 2004-10-16 Kieran Mansley <kjm25@cam.ac.uk>
2561 * tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
2562 even if one is already pending, if the rcv_wnd is above a threshold
2563 (currently TCP_WND/2). This avoids waiting for a timer to expire to send a
2564 delayed ACK in order to open the window if the stack is only receiving data.
2566 2004-09-12 Kieran Mansley <kjm25@cam.ac.uk>
2567 * tcp*.*: Retransmit time-out handling improvement by Sam Jansen.
2569 2004-08-20 Tony Mountifield <tony@softins.co.uk>
2570 * etharp.c: Make sure the first pbuf queued on an ARP entry
2571 is properly ref counted.
2573 2004-07-27 Tony Mountifield <tony@softins.co.uk>
2574 * debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
2575 warnings about comparison.
2576 * pbuf.c: Stopped compiler complaining of empty if statement
2577 when LWIP_DEBUGF() empty. Closed an unclosed comment.
2578 * tcp.c: Stopped compiler complaining of empty if statement
2579 when LWIP_DEBUGF() empty.
2580 * ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
2581 * inet.c: Added a couple of casts to quiet the compiler.
2582 No need to test isascii(c) before isdigit(c) or isxdigit(c).
2584 2004-07-22 Tony Mountifield <tony@softins.co.uk>
2585 * inet.c: Made data types consistent in inet_ntoa().
2586 Added casts for return values of checksum routines, to pacify compiler.
2587 * ip_frag.c, tcp_out.c, sockets.c, pbuf.c
2588 Small corrections to some debugging statements, to pacify compiler.
2590 2004-07-21 Tony Mountifield <tony@softins.co.uk>
2591 * etharp.c: Removed spurious semicolon and added missing end-of-comment.
2592 * ethernetif.c Updated low_level_output() to match prototype for
2593 netif->linkoutput and changed low_level_input() similarly for consistency.
2594 * api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
2595 of raw_recv() in raw.h and so avoid compiler error.
2596 * sockets.c: Added trivial (int) cast to keep compiler happier.
2597 * ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.
2603 2004-07-05 Leon Woestenberg <leon.woestenberg@gmx.net>
2604 * sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure
2605 your cc.h file defines this either 1 or 0. If non-defined,
2607 * .c: Added <string.h> and <errno.h> includes where used.
2608 * etharp.c: Made some array indices unsigned.
2610 2004-06-27 Leon Woestenberg <leon.woestenberg@gmx.net>
2611 * netif.*: Added netif_set_up()/down().
2612 * dhcp.c: Changes to restart program flow.
2614 2004-05-07 Leon Woestenberg <leon.woestenberg@gmx.net>
2615 * etharp.c: In find_entry(), instead of a list traversal per candidate, do a
2616 single-pass lookup for different candidates. Should exploit locality.
2618 2004-04-29 Leon Woestenberg <leon.woestenberg@gmx.net>
2619 * tcp*.c: Cleaned up source comment documentation for Doxygen processing.
2620 * opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC.
2621 * etharp.c: update_arp_entry() only adds new ARP entries when adviced to by
2622 the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option.
2626 2004-04-27 Leon Woestenberg <leon.woestenberg@gmx.net>
2627 * etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution
2628 suggested by Timmy Brolin. Fix for 32-bit processors that cannot access
2629 non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix
2630 is to prefix the 14-bit Ethernet headers with two padding bytes.
2632 2004-04-23 Leon Woestenberg <leon.woestenberg@gmx.net>
2633 * ip_addr.c: Fix in the ip_addr_isbroadcast() check.
2634 * etharp.c: Fixed the case where the packet that initiates the ARP request
2635 is not queued, and gets lost. Fixed the case where the packets destination
2636 address is already known; we now always queue the packet and perform an ARP
2643 * Fixed TCP bug for SYN_SENT to ESTABLISHED state transition.
2644 * Fixed TCP bug in dequeueing of FIN from out of order segment queue.
2645 * Fixed two possible NULL references in rare cases.
2651 * Fixed DHCP which did not include the IP address in DECLINE messages.
2655 * etharp.c has been hauled over a bit.
2661 * Fixed TCP bug induced by bad window resizing with unidirectional TCP traffic.
2662 * Packets sent from ARP queue had invalid source hardware address.
2666 * Pass-by ARP requests do now update the cache.
2670 * No longer dependent on ctype.h.
2671 * New socket options.
2672 * Raw IP pcb support.
2678 * Some debug formatters and casts fixed.
2679 * Numereous fixes in PPP.
2683 * DEBUGF now is LWIP_DEBUGF
2684 * pbuf_dechain() has been re-enabled.
2685 * Mentioned the changed use of CVS branches in README.
2691 * Fixed pool pbuf memory leak in pbuf_alloc().
2692 Occured if not enough PBUF_POOL pbufs for a packet pbuf chain.
2693 Reported by Savin Zlobec.
2695 * PBUF_POOL chains had their tot_len field not set for non-first
2696 pbufs. Fixed in pbuf_alloc().
2700 * Added PPP stack contributed by Marc Boucher
2704 * Now drops short packets for ICMP/UDP/TCP protocols. More robust.
2706 * ARP queueuing now queues the latest packet instead of the first.
2707 This is the RFC recommended behaviour, but can be overridden in
2714 * TCP has been fixed to deal with the new use of the pbuf->ref
2717 * DHCP dhcp_inform() crash bug fixed.
2721 * Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
2722 pbuf_refresh(). This has sped up pbuf pool operations considerably.
2723 Implemented by David Haas.
2729 * The packet buffer implementation has been enhanced to support
2730 zero-copy and copy-on-demand for packet buffers which have their
2731 payloads in application-managed memory.
2732 Implemented by David Haas.
2734 Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
2735 if an outgoing packet can be directly sent on the link, or perform
2736 a copy-on-demand when necessary.
2738 The application can safely assume the packet is sent, and the RAM
2739 is available to the application directly after calling udp_send()
2740 or similar function.
2744 * ARP_QUEUEING should now correctly work for all cases, including
2746 Implemented by Leon Woestenberg.
2750 * IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
2751 to a '0.0.0.0' IP address.
2753 * The packet buffer implementation is changed. The pbuf->ref counter
2754 meaning has changed, and several pbuf functions have been
2755 adapted accordingly.
2757 * netif drivers have to be changed to set the hardware address length field
2758 that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).
2759 See the contrib/ports/c16x cs8900 driver as a driver example.
2761 * netif's have a dhcp field that must be initialized to NULL by the driver.
2762 See the contrib/ports/c16x cs8900 driver as a driver example.
2764 (0.5.x) This file has been unmaintained up to 0.6.1. All changes are
2765 logged in CVS but have not been explained here.
2767 (0.5.3) Changes since version 0.5.2
2771 * memp_malloc(MEMP_API_MSG) could fail with multiple application
2772 threads because it wasn't protected by semaphores.
2776 * struct ip_addr now packed.
2778 * The name of the time variable in arp.c has been changed to ctime
2779 to avoid conflicts with the time() function.
2781 (0.5.2) Changes since version 0.5.1
2785 * A new TCP function, tcp_tmr(), now handles both TCP timers.
2789 * A bug in tcp_parseopt() could cause the stack to hang because of a
2790 malformed TCP option.
2792 * The address of new connections in the accept() function in the BSD
2793 socket library was not handled correctly.
2795 * pbuf_dechain() did not update the ->tot_len field of the tail.
2797 * Aborted TCP connections were not handled correctly in all
2802 * All protocol header structs are now packed.
2804 * The ->len field in the tcp_seg structure now counts the actual
2805 amount of data, and does not add one for SYN and FIN segments.
2807 (0.5.1) Changes since version 0.5.0
2811 * Possible to run as a user process under Linux.
2813 * Preliminary support for cross platform packed structs.
2815 * ARP timer now implemented.
2819 * TCP output queue length was badly initialized when opening
2822 * TCP delayed ACKs were not sent correctly.
2824 * Explicit initialization of BSS segment variables.
2826 * read() in BSD socket library could drop data.
2828 * Problems with memory alignment.
2830 * Situations when all TCP buffers were used could lead to
2833 * TCP MSS option wasn't parsed correctly.
2835 * Problems with UDP checksum calculation.
2837 * IP multicast address tests had endianess problems.
2839 * ARP requests had wrong destination hardware address.
2843 * struct eth_addr changed from u16_t[3] array to u8_t[6].
2845 * A ->linkoutput() member was added to struct netif.
2847 * TCP and UDP ->dest_* struct members where changed to ->remote_*.
2849 * ntoh* macros are now null definitions for big endian CPUs.
2851 (0.5.0) Changes since version 0.4.2
2855 * Redesigned operating system emulation layer to make porting easier.
2857 * Better control over TCP output buffers.
2859 * Documenation added.
2863 * Locking issues in buffer management.
2865 * Bugfixes in the sequential API.
2867 * IP forwarding could cause memory leakage. This has been fixed.
2871 * Directory structure somewhat changed; the core/ tree has been
2874 (0.4.2) Changes since version 0.4.1
2878 * Experimental ARP implementation added.
2880 * Skeleton Ethernet driver added.
2882 * Experimental BSD socket API library added.
2886 * In very intense situations, memory leakage could occur. This has
2891 * Variables named "data" and "code" have been renamed in order to
2892 avoid name conflicts in certain compilers.
2894 * Variable++ have in appliciable cases been translated to ++variable
2895 since some compilers generate better code in the latter case.
2897 (0.4.1) Changes since version 0.4
2901 * TCP: Connection attempts time out earlier than data
2902 transmissions. Nagle algorithm implemented. Push flag set on the
2903 last segment in a burst.
2905 * UDP: experimental support for UDP-Lite extensions.
2909 * TCP: out of order segments were in some cases handled incorrectly,
2910 and this has now been fixed. Delayed acknowledgements was broken
2911 in 0.4, has now been fixed. Binding to an address that is in use
2912 now results in an error. Reset connections sometimes hung an
2913 application; this has been fixed.
2915 * Checksum calculation sometimes failed for chained pbufs with odd
2916 lengths. This has been fixed.
2918 * API: a lot of bug fixes in the API. The UDP API has been improved
2919 and tested. Error reporting and handling has been
2920 improved. Logical flaws and race conditions for incoming TCP
2921 connections has been found and removed.
2923 * Memory manager: alignment issues. Reallocating memory sometimes
2924 failed, this has been fixed.
2926 * Generic library: bcopy was flawed and has been fixed.
2930 * API: all datatypes has been changed from generic ones such as
2931 ints, to specified ones such as u16_t. Functions that return
2932 errors now have the correct type (err_t).
2934 * General: A lot of code cleaned up and debugging code removed. Many
2935 portability issues have been fixed.
2937 * The license was changed; the advertising clause was removed.
2941 * Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri
2942 Kosunen, Mikael Caleres, and Frits Wilmink for reporting and
2945 (0.4) Changes since version 0.3.1
2947 * Memory management has been radically changed; instead of
2948 allocating memory from a shared heap, memory for objects that are
2949 rapidly allocated and deallocated is now kept in pools. Allocation
2950 and deallocation from those memory pools is very fast. The shared
2951 heap is still present but is used less frequently.
2953 * The memory, memory pool, and packet buffer subsystems now support
2954 4-, 2-, or 1-byte alignment.
2956 * "Out of memory" situations are handled in a more robust way.
2958 * Stack usage has been reduced.
2960 * Easier configuration of lwIP parameters such as memory usage,
2961 TTLs, statistics gathering, etc. All configuration parameters are
2962 now kept in a single header file "lwipopts.h".
2964 * The directory structure has been changed slightly so that all
2965 architecture specific files are kept under the src/arch
2968 * Error propagation has been improved, both in the protocol modules
2971 * The code for the RTXC architecture has been implemented, tested
2974 * Bugs have been found and corrected in the TCP, UDP, IP, API, and
2975 the Internet checksum modules.
2977 * Bugs related to porting between a 32-bit and a 16-bit architecture
2978 have been found and corrected.
2980 * The license has been changed slightly to conform more with the
2981 original BSD license, including the advertisement clause.
2983 (0.3.1) Changes since version 0.3
2985 * Fix of a fatal bug in the buffer management. Pbufs with allocated
2986 RAM never returned the RAM when the pbuf was deallocated.
2988 * TCP congestion control, window updates and retransmissions did not
2989 work correctly. This has now been fixed.
2991 * Bugfixes in the API.
2993 (0.3) Changes since version 0.2
2995 * New and improved directory structure. All include files are now
2996 kept in a dedicated include/ directory.
2998 * The API now has proper error handling. A new function,
2999 netconn_err(), now returns an error code for the connection in
3002 * Improvements in the memory management subsystem. The system now
3003 keeps a pointer to the lowest free memory block. A new function,
3004 mem_malloc2() tries to allocate memory once, and if it fails tries
3005 to free some memory and retry the allocation.
3007 * Much testing has been done with limited memory
3008 configurations. lwIP now does a better job when overloaded.
3010 * Some bugfixes and improvements to the buffer (pbuf) subsystem.
3012 * Many bugfixes in the TCP code:
3014 - Fixed a bug in tcp_close().
3016 - The TCP receive window was incorrectly closed when out of
3017 sequence segments was received. This has been fixed.
3019 - Connections are now timed-out of the FIN-WAIT-2 state.
3021 - The initial congestion window could in some cases be too
3022 large. This has been fixed.
3024 - The retransmission queue could in some cases be screwed up. This
3027 - TCP RST flag now handled correctly.
3029 - Out of sequence data was in some cases never delivered to the
3030 application. This has been fixed.
3032 - Retransmitted segments now contain the correct acknowledgment
3033 number and advertised window.
3035 - TCP retransmission timeout backoffs are not correctly computed
3036 (ala BSD). After a number of retransmissions, TCP now gives up
3039 * TCP connections now are kept on three lists, one for active
3040 connections, one for listening connections, and one for
3041 connections that are in TIME-WAIT. This greatly speeds up the fast
3042 timeout processing for sending delayed ACKs.
3044 * TCP now provides proper feedback to the application when a
3045 connection has been successfully set up.
3047 * More comments have been added to the code. The code has also been
3048 somewhat cleaned up.
3050 (0.2) Initial public release.
