9 2011-07-21: Simon Goldschmidt (patch by hanhui)
10 * ip4.c, etharp.c, pbuf.h: bug #33634 ip_forward() have a faulty behaviour:
11 Added pbuf flags to mark incoming packets as link-layer broadcast/multicast.
12 Also added code to allow ip_forward() to forward non-broadcast packets to
13 the input netif (set IP_FORWARD_ALLOW_TX_ON_RX_NETIF==1).
15 2011-07-21: Simon Goldschmidt
16 * sockets.c, opt.h: (bug #30185): added LWIP_FIONREAD_LINUXMODE that makes

20 * tcp.c, tcp_out.c: bug #33604: added some more asserts to check that
23 2011-05-25: Simon Goldschmidt
24 * again nearly the whole stack, renamed ip.c to ip4.c, ip_addr.c to ip4_addr.c,
25 combined ipv4/ipv6 inet_chksum.c, added ip.h, ip_addr.h: Combined IPv4
26 and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP
27 code so that the code is more readable.
29 2011-05-17: Patch by Ivan Delamer (only checked in by Simon Goldschmidt)
30 * nearly the whole stack: Finally, we got decent IPv6 support, big thanks to
31 Ivan! (this is work in progress: we're just post release anyway :-)
33 2011-05-14: Simon Goldschmidt (patch by Stéphane Lesage)
34 * tcpip.c/.h: patch #7449 allow tcpip callback from interrupt with static
40 2011-07-22: Simon Goldschmidt
41 * api_lib.c, api_msg.c, sockets.c, api.h: fixed bug #31084 (socket API returns
42 always EMSGSIZE on non-blocking sockets if data size > send buffers) -> now
43 lwip_send() sends as much as possible for non-blocking sockets
45 2011-07-22: Simon Goldschmidt
46 * pbuf.c/.h, timers.c: freeing ooseq pbufs when the pbuf pool is empty implemented
47 for NO_SYS==1: when not using sys_check_timeouts(), call PBUF_CHECK_FREE_OOSEQ()
48 at regular intervals from main level.
50 2011-07-21: Simon Goldschmidt
51 * etharp.c: fixed bug #33551 (ARP entries may time out although in use) by

75 2011-03-27: Simon Goldschmidt
76 * tcp_impl.h, tcp_in.c, tcp_out.c: Removed 'dataptr' from 'struct tcp_seg' and
77 calculate it in tcp_zero_window_probe (the only place where it was used).
79 2010-11-21: Simon Goldschmidt
80 * dhcp.c/.h: Added a function to deallocate the struct dhcp from a netif
83 2010-07-12: Simon Goldschmidt (patch by Stephane Lesage)

85 IP_MULTICAST_LOOP at socket- and raw-API level.
87 2010-06-16: Simon Goldschmidt
88 * ip.c: Added an optional define (LWIP_IP_ACCEPT_UDP_PORT) that can allow
89 link-layer-addressed UDP traffic to be received while a netif is down (just
90 like DHCP during configuration)
92 2010-05-22: Simon Goldschmidt
93 * many many files: bug #27352: removed packing from ip_addr_t, the packed
94 version is now only used in protocol headers. Added global storage for
95 current src/dest IP address while in input functions.
97 2010-05-16: Simon Goldschmidt
98 * def.h: task #10391: Add preprocessor-macros for compile-time htonl
99 calculation (and use them throughout the stack where applicable)
101 2010-05-16: Simon Goldschmidt
102 * opt.h, memp_std.h, memp.c, ppp_oe.h/.c: PPPoE now uses its own MEMP pool
103 instead of the heap (moved struct pppoe_softc from ppp_oe.c to ppp_oe.h)
105 2010-05-16: Simon Goldschmidt
106 * opt.h, memp_std.h, dns.h/.c: DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses its own
107 MEMP pool instead of the heap

119 * udp.h/.c, pbuf.h/.c: task #6849: added udp_send(_to/_if) functions that
120 take a precalculated checksum, added pbuf_fill_chksum() to copy data
121 into a pbuf and at the same time calculating the checksum for that data
123 2010-04-29: Simon Goldschmidt
124 * ip_addr.h, etharp.h/.c, autoip.c: Create overridable macros for copying
125 2-byte-aligned IP addresses and MAC addresses

130 2010-04-14: Simon Goldschmidt
131 * tcpip.h/.c, timers.c: Added an overridable define to get informed when the
132 tcpip_thread processes messages or timeouts to implement a watchdog.
134 2010-03-28: Simon Goldschmidt
135 * ip_frag.c: create a new (contiguous) PBUF_RAM for every outgoing

138 2010-03-27: Simon Goldschmidt
139 * etharp.c: Speedup TX by moving code from find_entry to etharp_output/
140 etharp_query to prevent unnecessary function calls (inspired by
143 2010-03-20: Simon Goldschmidt
144 * opt.h, tcpip.c/.h: Added an option to disable tcpip_(un)timeout code
145 since the linker cannot do this automatically to save space.
147 2010-03-20: Simon Goldschmidt

152 when creating TCP segments, not when (re-)transmitting them.
154 2010-03-07: Simon Goldschmidt
155 * sockets.c: bug #28775 (select/event_callback: only check select_cb_list
156 on change) plus use SYS_LIGHTWEIGHT_PROT to protect the select code.
157 This should speed up receiving data on sockets as the select code in
158 event_callback is only executed when select is waiting.
160 2010-03-06: Simon Goldschmidt
161 * tcp_out.c: task #7013 (Create option to have all packets delivered to
162 netif->output in one piece): Always copy to try to create single pbufs
165 2010-03-06: Simon Goldschmidt
166 * api.h, api_lib.c, sockets.c: task #10167 (sockets: speed up TCP recv
167 by not allocating a netbuf): added function netconn_recv_tcp_pbuf()
168 for tcp netconns to receive pbufs, not netbufs; use that function
171 2010-03-05: Jakob Ole Stoklundsen / Simon Goldschmidt
172 * opt.h, tcp.h, tcp_impl.h, tcp.c, tcp_in.c, tcp_out.c: task #7040:
173 Work on tcp_enqueue: Don't waste memory when chaining segments,
174 added option TCP_OVERSIZE to prevent creating many small pbufs when
175 calling tcp_write with many small blocks of data. Instead, pbufs are
176 allocated larger than needed and the space is used for later calls to
179 2010-02-21: Simon Goldschmidt
180 * stats.c/.h: Added const char* name to mem- and memp-stats for easier
183 2010-02-21: Simon Goldschmidt

200 * dhcp.c/.h, autoip.c/.h: task #10139 (Prefer statically allocated
201 memory): added autoip_set_struct() and dhcp_set_struct() to let autoip
202 and dhcp work with user-allocated structs instead of callin mem_malloc
204 2010-02-12: Simon Goldschmidt/Jeff Barber
205 * tcp.c/h: patch #6865 (SO_REUSEADDR for TCP): if pcb.so_options has
206 SOF_REUSEADDR set, allow binding to endpoint in TIME_WAIT
208 2010-02-12: Simon Goldschmidt
209 * sys layer: task #10139 (Prefer statically allocated memory): converted
210 mbox and semaphore functions to take pointers to sys_mbox_t/sys_sem_t;
211 converted sys_mbox_new/sys_sem_new to take pointers and return err_t;
212 task #7212: Add Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX
213 to let sys.h use binary semaphores instead of mutexes - as before)
215 2010-02-09: Simon Goldschmidt (Simon Kallweit)
216 * timers.c/.h: Added function sys_restart_timeouts() from patch #7085
217 (Restart system timeout handling)

220 * netif.c/.h, removed loopif.c/.h: task #10153 (Integrate loopif into
221 netif.c) - loopif does not have to be created by the port any more,
222 just define LWIP_HAVE_LOOPIF to 1.
224 2010-02-08: Simon Goldschmidt
225 * inet.h, ip_addr.c/.h: Added reentrant versions of inet_ntoa/ipaddr_ntoa

236 make changing the actual implementation behind the typedef easier.
238 2010-02-01: Simon Goldschmidt
239 * opt.h, memp_std.h, dns.h, netdb.c, memp.c: Let netdb use a memp pool
240 for allocating memory when getaddrinfo() is called.
242 2010-01-31: Simon Goldschmidt
243 * dhcp.h, dhcp.c: Reworked the code that parses DHCP options: parse
244 them once instead of parsing for every option. This also removes
245 the need for mem_malloc from dhcp_recv and makes it possible to
246 correctly retrieve the BOOTP file.
248 2010-01-30: simon Goldschmidt
249 * sockets.c: Use SYS_LIGHTWEIGHT_PROT instead of a semaphore to protect

270 by adding ppp_set_netif_statuscallback()/ppp_set_netif_linkcallback()
272 2010-01-13: Simon Goldschmidt
273 * mem.c: The heap now may be moved to user-defined memory by defining
274 LWIP_RAM_HEAP_POINTER as a void pointer to that memory's address
275 (patch #6966 and bug #26133)
277 2010-01-10: Simon Goldschmidt (Bill Auerbach)
278 * opt.h, memp.c: patch #6822 (Add option to place memory pools in

287 added timers.c/.h: Separated timer implementation from semaphore/mbox
288 implementation, moved timer implementation to timers.c/.h, timers are
289 now only called from tcpip_thread or by explicitly checking them.
292 2009-12-27: Simon Goldschmidt
293 * opt.h, etharp.h/.c, init.c, tcpip.c: Added an additional option
294 LWIP_ETHERNET to support ethernet without ARP (necessary for pure PPPoE)
299 2011-04-20: Simon Goldschmidt
300 * sys_arch.txt: sys_arch_timeouts() is not needed any more.
302 2011-04-13: Simon Goldschmidt
303 * tcp.c, udp.c: Fixed bug #33048 (Bad range for IP source port numbers) by
304 using ports in the IANA private/dynamic range (49152 through 65535).
306 2011-03-29: Simon Goldschmidt, patch by Emil Lhungdahl:
307 * etharp.h/.c: Fixed broken VLAN support.
309 2011-03-27: Simon Goldschmidt
310 * tcp.c: Fixed bug #32926 (TCP_RMV(&tcp_bound_pcbs) is called on unbound tcp
311 pcbs) by checking if the pcb was bound (local_port != 0).

321 * tcp_out.c: Fixed bug #32820 (Outgoing TCP connections created before route
322 is present never times out) by starting retransmission timer before checking
325 2011-03-22: Simon Goldschmidt
326 * ppp.c: Fixed bug #32648 (PPP code crashes when terminating a link) by only
327 calling sio_read_abort() if the file descriptor is valid.
329 2011-03-14: Simon Goldschmidt
330 * err.h/.c, sockets.c, api_msg.c: fixed bug #31748 (Calling non-blocking connect
331 more than once can render a socket useless) since it mainly involves changing
332 "FATAL" classification of error codes: ERR_USE and ERR_ISCONN just aren't fatal.
334 2011-03-13: Simon Goldschmidt
335 * sockets.c: fixed bug #32769 (ESHUTDOWN is linux-specific) by fixing

492 * various files: Fixed compiling with different options disabled (TCP/UDP),
493 triggered by bug #29345; don't allocate acceptmbox if LWIP_TCP is disabled
495 2010-03-25: Simon Goldschmidt
496 * sockets.c: Fixed bug #29332: lwip_select() processes readset incorrectly
498 2010-03-25: Simon Goldschmidt
499 * tcp_in.c, test_tcp_oos.c: Fixed bug #29080: Correctly handle remote side
500 overrunning our rcv_wnd in ooseq case.
502 2010-03-22: Simon Goldschmidt
503 * tcp.c: tcp_listen() did not copy the pcb's prio.
505 2010-03-19: Simon Goldschmidt
506 * snmp_msg.c: Fixed bug #29256: SNMP Trap address was not correctly set
508 2010-03-14: Simon Goldschmidt
509 * opt.h, etharp.h: Fixed bug #29148 (Incorrect PBUF_POOL_BUFSIZE for ports
510 where ETH_PAD_SIZE > 0) by moving definition of ETH_PAD_SIZE to opt.h
511 and basing PBUF_LINK_HLEN on it.
513 2010-03-08: Simon Goldschmidt
514 * netif.c, ipv4/ip.c: task #10241 (AutoIP: don't break existing connections
515 when assiging routable address): when checking incoming packets and
516 aborting existing connection on address change, filter out link-local
519 2010-03-06: Simon Goldschmidt
520 * sockets.c: Fixed LWIP_NETIF_TX_SINGLE_PBUF for LWIP_TCPIP_CORE_LOCKING
522 2010-03-06: Simon Goldschmidt
523 * ipv4/ip.c: Don't try to forward link-local addresses

541 2010-02-20: Simon Goldschmidt
542 * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Task #10088: Correctly implement
543 close() vs. shutdown(). Now the application does not get any more
544 recv callbacks after calling tcp_close(). Added tcp_shutdown().
546 2010-02-19: Simon Goldschmidt
547 * mem.c/.h, pbuf.c: Renamed mem_realloc() to mem_trim() to prevent
548 confusion with realloc()
550 2010-02-15: Simon Goldschmidt/Stephane Lesage
551 * netif.c/.h: Link status does not depend on LWIP_NETIF_LINK_CALLBACK
554 2010-02-14: Simon Goldschmidt
555 * netif.c: Fixed bug #28877 (Duplicate ARP gratuitous packet with
556 LWIP_NETIF_LINK_CALLBACK set on) by only sending if both link- and
557 admin-status of a netif are up
559 2010-02-14: Simon Goldschmidt
560 * opt.h: Disable ETHARP_TRUST_IP_MAC by default since it slows down packet
561 reception and is not really necessary
563 2010-02-14: Simon Goldschmidt
564 * etharp.c/.h: Fixed ARP input processing: only add a new entry if a
565 request was directed as us (RFC 826, Packet Reception), otherwise
566 only update existing entries; internalized some functions
568 2010-02-14: Simon Goldschmidt
569 * netif.h, etharp.c, tcpip.c: Fixed bug #28183 (ARP and TCP/IP cannot be
570 disabled on netif used for PPPoE) by adding a new netif flag
571 (NETIF_FLAG_ETHERNET) that tells the stack the device is an ethernet
572 device but prevents usage of ARP (so that ethernet_input can be used
575 2010-02-12: Simon Goldschmidt
576 * netif.c: netif_set_link_up/down: only do something if the link state
579 2010-02-12: Simon Goldschmidt/Stephane Lesage

588 (recv() makes receive window update for data that wasn't received by
591 2010-02-09: Simon Goldschmidt/Stephane Lesage
592 * sockets.c: Fixed bug #28853 (lwip_recvfrom() returns 0 on receive time-out
593 or any netconn_recv() error)
595 2010-02-09: Simon Goldschmidt
596 * ppp.c: task #10154 (PPP: Update snmp in/out counters for tx/rx packets)
598 2010-02-09: Simon Goldschmidt
599 * netif.c: For loopback packets, adjust the stats- and snmp-counters
600 for the loopback netif.
602 2010-02-08: Simon Goldschmidt
603 * igmp.c/.h, ip.h: Moved most defines from igmp.h to igmp.c for clarity
604 since they are not used anywhere else.
606 2010-02-08: Simon Goldschmidt (Stéphane Lesage)
607 * igmp.c, igmp.h, stats.c, stats.h: Improved IGMP stats
608 (patch from bug #28798)

612 another bug when LWIP_RAND() returns zero.
614 2010-02-04: Simon Goldschmidt
615 * nearly every file: Use macros defined in ip_addr.h (some of them new)
616 to work with IP addresses (preparation for bug #27352 - Change ip_addr
617 from struct to typedef (u32_t) - and better code).
619 2010-01-31: Simon Goldschmidt
620 * netif.c: Don't call the link-callback from netif_set_up/down() since
621 this invalidly retriggers DHCP.
623 2010-01-29: Simon Goldschmidt
624 * ip_addr.h, inet.h, def.h, inet.c, def.c, more: Cleanly separate the
625 portability file inet.h and its contents from the stack: moved htonX-
626 functions to def.h (and the new def.c - they are not ipv4 dependent),
627 let inet.h depend on ip_addr.h and not the other way round.
628 This fixes bug #28732.
630 2010-01-28: Kieran Mansley
631 * tcp.c: Ensure ssthresh >= 2*MSS
633 2010-01-27: Simon Goldschmidt
634 * tcp.h, tcp.c, tcp_in.c: Fixed bug #27871: Calling tcp_abort() in recv
635 callback can lead to accessing unallocated memory. As a consequence,
636 ERR_ABRT means the application has called tcp_abort()!
638 2010-01-25: Simon Goldschmidt
639 * snmp_structs.h, msg_in.c: Partly fixed bug #22070 (MIB_OBJECT_WRITE_ONLY
640 not implemented in SNMP): write-only or not-accessible are still
641 returned by getnext (though not by get)
643 2010-01-24: Simon Goldschmidt
644 * snmp: Renamed the private mib node from 'private' to 'mib_private' to
645 not use reserved C/C++ keywords
647 2010-01-23: Simon Goldschmidt
648 * sockets.c: Fixed bug #28716: select() returns 0 after waiting for less

660 bugfix backports from 2.4.x.
662 2010-01-18: Simon Goldschmidt

668 error return value to struct api_msg_msg
670 2010-01-17: Simon Goldschmidt
671 * api.h, api_lib.c, sockets.c: Changed netconn_recv() and netconn_accept()

674 2010-01-14: Simon Goldschmidt
675 * ...: Use typedef for function prototypes throughout the stack.
677 2010-01-13: Simon Goldschmidt

679 window = 0) by correctly draining recvmbox/acceptmbox
681 2010-01-11: Simon Goldschmidt

683 erroneous callbacks) by copying the code from recent pppd
685 2010-01-10: Simon Goldschmidt
686 * raw.c: Fixed bug #28506 (raw_bind should filter received packets)

694 2010-01-08: Simon Goldschmidt
695 * dns.c: Copy hostname for DNS_LOCAL_HOSTLIST_IS_DYNAMIC==1 since string
696 passed to dns_local_addhost() might be volatile
698 2010-01-07: Simon Goldschmidt
699 * timers.c, tcp.h: Call tcp_timer_needed() with NO_SYS==1, too
701 2010-01-06: Simon Goldschmidt
702 * netdb.h: Fixed bug #28496: missing include guards in netdb.h
704 2009-12-31: Simon Goldschmidt
705 * many ppp files: Reorganised PPP source code from ucip structure to pppd
706 structure to easily compare our code against the pppd code (around v2.3.1)
708 2009-12-27: Simon Goldschmidt
709 * tcp_in.c: Another fix for bug #28241 (ooseq processing) and adapted

757 could have non-zero length
759 2009-12-02: Simon Goldschmidt

765 sequence queue, also fixed PBUF_POOL leak in the out-of-sequence code
767 2009-11-29: Simon Goldschmidt
768 * pbuf.c: Fixed bug #28064: pbuf_alloc(PBUF_POOL) is not thread-safe by
769 queueing a call into tcpip_thread to free ooseq-bufs if the pool is empty
771 2009-11-26: Simon Goldschmidt

797 2009-10-28: Kieran Mansley
798 * tcp_in.c, tcp_out.c, tcp.h: re-work the fast retransmission code
799 to follow algorithm from TCP/IP Illustrated
801 2009-10-27: Kieran Mansley

821 2009-10-19: Simon Goldschmidt
822 * dhcp.c/.h: Minor code simplification (don't store received pbuf, change

824 testing for valid reply
826 2009-10-19: Simon Goldschmidt
827 * dhcp.c: Removed most calls to udp_connect since they aren't necessary
828 when using udp_sendto_if() - always stay connected to IP_ADDR_ANY.
830 2009-10-16: Simon Goldschmidt
831 * ip.c: Fixed bug #27390: Source IP check in ip_input() causes it to drop

887 2009-05-10 Simon Goldschmidt
888 * opt.h, sockets.c, pbuf.c, netbuf.h, pbuf.h: task #7013: Added option
889 LWIP_NETIF_TX_SINGLE_PBUF to try to create transmit packets from only
890 one pbuf to help MACs that don't support scatter-gather DMA.
892 2009-05-09 Simon Goldschmidt
893 * icmp.h, icmp.c: Shrinked ICMP code, added option to NOT check icoming
894 ECHO pbuf for size (just use it): LWIP_ICMP_ECHO_CHECK_INPUT_PBUF_LEN
896 2009-05-05 Simon Goldschmidt, Jakob Stoklund Olesen
897 * ip.h, ip.c: Added ip_current_netif() & ip_current_header() to receive

936 2009-01-28 Jonathan Larmour (suggested by Bill Bauerbach)
937 * ipv4/inet_chksum.c, ipv4/lwip/inet_chksum.h: inet_chksum_pseudo_partial()
938 is only used by UDPLITE at present, so conditionalise it.
940 2008-12-03 Simon Goldschmidt (base on patch from Luca Ceresoli)
941 * autoip.c: checked in (slightly modified) patch #6683: Customizable AUTOIP
942 "seed" address. This should reduce AUTOIP conflicts if
943 LWIP_AUTOIP_CREATE_SEED_ADDR is overridden.
945 2008-10-02 Jonathan Larmour and Rishi Khan
946 * sockets.c (lwip_accept): Return EWOULDBLOCK if would block on non-blocking
949 2008-06-30 Simon Goldschmidt
950 * mem.c, opt.h, stats.h: fixed bug #21433: Calling mem_free/pbuf_free from
951 interrupt context isn't safe: LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT allows
952 mem_free to run between mem_malloc iterations. Added illegal counter for
955 2008-06-27 Simon Goldschmidt
956 * stats.h/.c, some other files: patch #6483: stats module improvement:

986 2009-07-27 Kieran Mansley
987 * api.h api_msg.h netdb.h sockets.h: add missing #include directives
989 2009-07-09 Kieran Mansley
990 * api_msg.c, sockets.c, api.h: BUG23240 use signed counters for
991 recv_avail and don't increment counters until message successfully

1001 2009-06-25 Kieran Mansley
1002 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: BUG26301 and BUG26267: correct
1003 simultaneous close behaviour, and make snd_nxt have the same meaning
1006 2009-05-12 Simon Goldschmidt
1007 * etharp.h, etharp.c, netif.c: fixed bug #26507: "Gratuitous ARP depends on
1008 arp_table / uses etharp_query" by adding etharp_gratuitous()
1010 2009-05-12 Simon Goldschmidt
1011 * ip.h, ip.c, igmp.c: bug #26487: Added ip_output_if_opt that can add IP options
1012 to the IP header (used by igmp_ip_output_if)
1014 2009-05-06 Simon Goldschmidt
1015 * inet_chksum.c: On little endian architectures, use LWIP_PLATFORM_HTONS (if
1016 defined) for SWAP_BYTES_IN_WORD to speed up checksumming.
1018 2009-05-05 Simon Goldschmidt
1019 * sockets.c: bug #26405: Prematurely released semaphore causes lwip_select()

1045 2009-04-29 Frédéric Bernon
1046 * raw.c, udp.c, init.c, opt.h, ip.h, sockets.h: bug #26309: Implement the
1047 SO(F)_BROADCAST filter for all API layers. Avoid the unindented reception
1048 of broadcast packets even when this option wasn't set. Port maintainers
1049 which want to enable this filter have to set IP_SOF_BROADCAST=1 in opt.h.
1050 If you want this option also filter broadcast on recv operations, you also
1051 have to set IP_SOF_BROADCAST_RECV=1 in opt.h.
1053 2009-04-28 Simon Goldschmidt, Jakob Stoklund Olesen

1063 * memp.c, mem.c, memp.h, mem_std.h: bug #26213 "Problem with memory allocation
1064 when debugging": memp_sizes contained the wrong sizes (including sanity
1065 regions); memp pools for MEM_USE_POOLS were too small
1067 2009-04-24 Simon Goldschmidt, Frédéric Bernon
1068 * inet.c: patch #6765: Fix a small problem with the last changes (incorrect
1069 behavior, with with ip address string not ended by a '\0', a space or a

1182 * tcp_in.c: fixed bug ##24596: Vulnerability on faulty TCP options length
1185 2008-10-15 Simon Goldschmidt
1186 * ip_frag.c: fixed bug #24517: IP reassembly crashes on unaligned IP headers
1187 by packing the struct ip_reass_helper.
1189 2008-10-03 David Woodhouse, Jonathan Larmour
1190 * etharp.c (etharp_arp_input): Fix type aliasing problem copying ip address.
1192 2008-10-02 Jonathan Larmour
1193 * dns.c: Hard-code structure sizes, to avoid issues on some compilers where
1194 padding is included.
1196 2008-09-30 Jonathan Larmour
1197 * sockets.c (lwip_accept): check addr isn't NULL. If it's valid, do an
1198 assertion check that addrlen isn't NULL.
1200 2008-09-30 Jonathan Larmour
1201 * tcp.c: Fix bug #24227, wrong error message in tcp_bind.

1205 inet.h -> moved declaration of struct in_addr from ip_addr.h to inet.h
1207 2008-08-14 Simon Goldschmidt
1208 * api_msg.c: fixed bug #23847: do_close_internal references freed memory (when
1209 tcp_close returns != ERR_OK)
1211 2008-07-08 Frédéric Bernon
1212 * stats.h: Fix some build bugs introduced with patch #6483 (missing some parameters
1213 in macros, mainly if MEM_STATS=0 and MEMP_STATS=0).
1215 2008-06-24 Jonathan Larmour
1216 * tcp_in.c: Fix for bug #23693 as suggested by Art R. Ensure cseg is unused
1217 if tcp_seg_copy fails.
1219 2008-06-17 Simon Goldschmidt
1220 * inet_chksum.c: Checked in some ideas of patch #6460 (loop optimizations)
1221 and created defines for swapping bytes and folding u32 to u16.
1223 2008-05-30 Kieran Mansley
1224 * tcp_in.c Remove redundant "if" statement, and use real rcv_wnd
1225 rather than rcv_ann_wnd when deciding if packets are in-window.
1226 Contributed by <arasmussen@consultant.datasys.swri.edu>
1228 2008-05-30 Kieran Mansley
1229 * mem.h: Fix BUG#23254. Change macro definition of mem_* to allow
1230 passing as function pointers when MEM_LIBC_MALLOC is defined.
1232 2008-05-09 Jonathan Larmour
1233 * err.h, err.c, sockets.c: Fix bug #23119: Reorder timeout error code to
1234 stop it being treated as a fatal error.
1236 2008-04-15 Simon Goldschmidt
1237 * dhcp.c: fixed bug #22804: dhcp_stop doesn't clear NETIF_FLAG_DHCP
1240 2008-03-27 Simon Goldschmidt
1241 * mem.c, tcpip.c, tcpip.h, opt.h: fixed bug #21433 (Calling mem_free/pbuf_free
1242 from interrupt context isn't safe): set LWIP_USE_HEAP_FROM_INTERRUPT to 1
1243 in lwipopts.h or use pbuf_free_callback(p)/mem_free_callback(m) to free pbufs
1244 or heap memory from interrupt context
1246 2008-03-26 Simon Goldschmidt
1247 * tcp_in.c, tcp.c: fixed bug #22249: division by zero could occur if a remote
1248 host sent a zero mss as TCP option.
1255 2008-03-10 Jonathan Larmour
1256 * inet_chksum.c: Allow choice of one of the sample algorithms to be
1257 made from lwipopts.h. Fix comment on how to override LWIP_CHKSUM.
1259 2008-01-22 Frédéric Bernon
1260 * tcp.c, tcp_in.c, tcp.h, opt.h: Rename LWIP_CALCULATE_EFF_SEND_MSS in
1261 TCP_CALCULATE_EFF_SEND_MSS to have coherent TCP options names.
1263 2008-01-14 Frédéric Bernon
1264 * rawapi.txt, api_msg.c, tcp.c, tcp_in.c, tcp.h: changes for task #7675 "Enable
1265 to refuse data on a TCP_EVENT_RECV call". Important, behavior changes for the
1266 tcp_recv callback (see rawapi.txt).
1268 2008-01-14 Frédéric Bernon, Marc Chaland
1269 * ip.c: Integrate patch #6369" ip_input : checking before realloc".
1271 2008-01-12 Frédéric Bernon
1272 * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
1273 netconn::sem per netconn::op_completed like suggested for the task #7490
1274 "Add return value to sys_mbox_post".
1276 2008-01-12 Frédéric Bernon
1277 * api_msg.c, opt.h: replace DEFAULT_RECVMBOX_SIZE per DEFAULT_TCP_RECVMBOX_SIZE,
1278 DEFAULT_UDP_RECVMBOX_SIZE and DEFAULT_RAW_RECVMBOX_SIZE (to optimize queues
1279 sizes), like suggested for the task #7490 "Add return value to sys_mbox_post".
1281 2008-01-10 Frédéric Bernon
1282 * tcpip.h, tcpip.c: add tcpip_callback_with_block function for the task #7490
1283 "Add return value to sys_mbox_post". tcpip_callback is always defined as
1284 "blocking" ("block" parameter = 1).
1286 2008-01-10 Frédéric Bernon
1287 * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
1288 netconn::mbox (sys_mbox_t) per netconn::sem (sys_sem_t) for the task #7490
1289 "Add return value to sys_mbox_post".
1291 2008-01-05 Frédéric Bernon
1292 * sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h, opt.h:
1293 Introduce changes for task #7490 "Add return value to sys_mbox_post" with some
1294 modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which
1295 indicate the number of pointers query by the mailbox. There is three defines
1296 in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the
1297 netconn::acceptmbox. Port maintainers, you can decide to just add this new
1298 parameter in your implementation, but to ignore it to keep the previous behavior.
1299 The new sys_mbox_trypost function return a value to know if the mailbox is
1300 full or if the message is posted. Take a look to sys_arch.txt for more details.
1301 This new function is used in tcpip_input (so, can be called in an interrupt
1302 context since the function is not blocking), and in recv_udp and recv_raw.
1304 2008-01-04 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
1305 * rawapi.txt, api.h, api_lib.c, api_msg.h, api_msg.c, sockets.c, tcp.h, tcp.c,
1306 tcp_in.c, init.c, opt.h: rename backlog options with TCP_ prefix, limit the
1307 "backlog" parameter in an u8_t, 0 is interpreted as "smallest queue", add
1308 documentation in the rawapi.txt file.
1310 2007-12-31 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
1311 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Add TCP persist timer
1313 2007-12-31 Frédéric Bernon, Luca Ceresoli
1314 * autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP packets
1315 in autoip". The change in etharp_raw could be removed, since all calls to
1316 etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be
1317 wrong in the future.
1319 2007-12-30 Frédéric Bernon, Tom Evans
1320 * ip.c: Fix bug #21846 "LwIP doesn't appear to perform any IP Source Address
1321 Filtering" reported by Tom Evans.
1323 2007-12-21 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
1324 * tcp.h, opt.h, api.h, api_msg.h, tcp.c, tcp_in.c, api_lib.c, api_msg.c,
1325 sockets.c, init.c: task #7252: Implement TCP listen backlog: Warning: raw API
1326 applications have to call 'tcp_accepted(pcb)' in their accept callback to
1327 keep accepting new connections.
1329 2007-12-13 Frédéric Bernon
1330 * api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum dns_result"
1331 by err_t type. Add a new err_t code "ERR_INPROGRESS".
1333 2007-12-12 Frédéric Bernon
1334 * dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles
1335 are the one which have ram usage.
1337 2007-12-05 Frédéric Bernon
1338 * netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static
1339 set of variables (=0) or a local one (=1). In this last case, your port should
1340 provide a function "struct hostent* sys_thread_hostent( struct hostent* h)"
1341 which have to do a copy of "h" and return a pointer ont the "per-thread" copy.
1343 2007-12-03 Simon Goldschmidt
1344 * ip.c: ip_input: check if a packet is for inp first before checking all other
1345 netifs on netif_list (speeds up packet receiving in most cases)
1347 2007-11-30 Simon Goldschmidt
1348 * udp.c, raw.c: task #7497: Sort lists (pcb, netif, ...) for faster access
1349 UDP: move a (connected) pcb selected for input to the front of the list of
1350 pcbs so that it is found faster next time. Same for RAW pcbs that have eaten
1353 2007-11-28 Simon Goldschmidt
1354 * etharp.c, stats.c, stats.h, opt.h: Introduced ETHARP_STATS
1356 2007-11-25 Simon Goldschmidt
1357 * dhcp.c: dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy
1360 2007-11-24 Simon Goldschmidt
1361 * netdb.h, netdb.c, sockets.h/.c: Moved lwip_gethostbyname from sockets.c
1362 to the new file netdb.c; included lwip_getaddrinfo.
1364 2007-11-21 Simon Goldschmidt
1365 * tcp.h, opt.h, tcp.c, tcp_in.c: implemented calculating the effective send-mss
1366 based on the MTU of the netif used to send. Enabled by default. Disable by
1367 setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21492.
1369 2007-11-19 Frédéric Bernon
1370 * api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name
1371 received match the name query), implement DNS_USES_STATIC_BUF (the place where
1372 copy dns payload to parse the response), return an error if there is no place
1373 for a new query, and fix some minor problems.
1375 2007-11-16 Simon Goldschmidt
1376 * new files: ipv4/inet.c, ipv4/inet_chksum.c, ipv6/inet6.c
1377 removed files: core/inet.c, core/inet6.c
1378 Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into
1379 inet and chksum part; changed includes in all lwIP files as appropriate
1381 2007-11-16 Simon Goldschmidt
1382 * api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential
1383 dns resolver function for netconn api (netconn_gethostbyname) and socket api
1384 (gethostbyname/gethostbyname_r).
1386 2007-11-15 Jim Pettinato, Frédéric Bernon
1387 * opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name
1388 requests with RAW api interface. Initialization is done in lwip_init() with
1389 build time options. DNS timer is added in tcpip_thread context. DHCP can set
1390 DNS server ip addresses when options are received. You need to set LWIP_DNS=1
1391 in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get
1392 some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo"
1393 list with points to improve.
1395 2007-11-06 Simon Goldschmidt
1396 * opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly
1397 enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status
1398 for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.
1400 2007-11-06 Simon Goldschmidt
1401 * api.h, api_msg.h and dependent files: Task #7410: Removed the need to include
1402 core header files in api.h (ip/tcp/udp/raw.h) to hide the internal
1403 implementation from netconn api applications.
1405 2007-11-03 Frédéric Bernon
1406 * api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP &
1407 RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled
1408 by default). Netconn API users can use the netconn_recv_bufsize macro to access
1409 it. This is a first release which have to be improve for TCP. Note it used the
1410 netconn::recv_avail which need to be more "thread-safe" (note there is already
1411 the problem for FIONREAD with lwip_ioctl/ioctlsocket).
1413 2007-11-01 Frédéric Bernon, Marc Chaland
1414 * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c:
1415 Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api
1416 layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api
1417 layer. This option enable to delayed TCP PUSH flag on multiple "write" calls.
1418 Note that previous "copy" parameter for "write" APIs is now called "apiflags".
1420 2007-10-24 Frédéric Bernon
1421 * api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than
1422 TCP_EVENT_xxx macros to get a code more readable. It could also help to remove
1423 some code (like we have talk in "patch #5919 : Create compile switch to remove
1424 select code"), but it could be done later.
1426 2007-10-08 Simon Goldschmidt
1427 * many files: Changed initialization: many init functions are not needed any
1428 more since we now rely on the compiler initializing global and static
1431 2007-10-06 Simon Goldschmidt
1432 * ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY
1433 to enqueue the received pbufs so that multiple packets can be reassembled
1434 simultaneously and no static reassembly buffer is needed.
1436 2007-10-05 Simon Goldschmidt
1437 * tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so
1438 all netifs (or ports) can use it.
1440 2007-10-05 Frédéric Bernon
1441 * netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the
1442 common function to reduce a little bit the footprint (for all functions using
1443 only the "netif" parameter).
1445 2007-10-03 Frédéric Bernon
1446 * netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down,
1447 netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce
1448 a little bit the footprint (for all functions using only the "netif" parameter).
1450 2007-09-15 Frédéric Bernon
1451 * udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF
1452 option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for
1453 netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for
1454 IP_MULTICAST_TTL and IP_MULTICAST_IF.
1456 2007-09-10 Frédéric Bernon
1457 * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles
1458 even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime()
1459 each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can
1460 decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but
1461 call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime()
1462 or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
1463 This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
1464 snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
1465 when it's queried (any direct call to "sysuptime" is changed by a call to
1466 snmp_get_sysuptime).
1468 2007-09-09 Frédéric Bernon, Bill Florac
1469 * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP,
1470 and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags
1471 if you want IGMP on an interface. igmp_stop() is now called inside netif_remove().
1472 igmp_report_groups() is now called inside netif_set_link_up() (need to have
1473 LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait
1474 the next query message to receive the matching multicast streams).
1476 2007-09-08 Frédéric Bernon
1477 * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains
1478 IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change).
1479 Use this new field to access to common pcb fields (ttl, tos, so_options, etc...).
1480 Enable to access to these fields with LWIP_TCP=0.
1482 2007-09-05 Frédéric Bernon
1483 * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h,
1484 ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option
1485 LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default).
1486 Be careful, disabling ICMP make your product non-compliant to RFC1122, but
1487 help to reduce footprint, and to reduce "visibility" on the Internet.
1489 2007-09-05 Frédéric Bernon, Bill Florac
1490 * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list
1491 for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new
1492 parameters have to be provided: a task name, and a task stack size. For this
1493 one, since it's platform dependant, you could define the best one for you in
1494 your lwipopts.h. For port maintainers, you can just add these new parameters
1495 in your sys_arch.c file, and but it's not mandatory, use them in your OS
1498 2007-09-05 Frédéric Bernon
1499 * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings
1500 inside init.c for task #7142 "Sanity check user-configurable values".
1502 2007-09-04 Frédéric Bernon, Bill Florac
1503 * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by
1504 memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the
1505 value). It will avoid potential fragmentation problems, use a counter to know
1506 how many times a group is used on an netif, and free it when all applications
1507 leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity
1508 check if LWIP_IGMP!=0).
1510 2007-09-03 Frédéric Bernon
1511 * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement".
1512 Initialize igmp_mac_filter to NULL in netif_add (this field should be set in
1513 the netif's "init" function). Use the "imr_interface" field (for socket layer)
1514 and/or the "interface" field (for netconn layer), for join/leave operations.
1515 The igmp_join/leavegroup first parameter change from a netif to an ipaddr.
1516 This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany).
1518 2007-08-30 Frédéric Bernon
1519 * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions
1520 from api/api_lib". Now netbuf API is independant of netconn, and can be used
1521 with other API (application based on raw API, or future "socket2" API). Ports
1522 maintainers just have to add src/api/netbuf.c in their makefile/projects.
1524 2007-08-30 Frédéric Bernon, Jonathan Larmour
1525 * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check
1526 user-configurable values".
1528 2007-08-29 Frédéric Bernon
1529 * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start.
1530 igmp_start is call inside netif_add. Now, igmp initialization is in the same
1531 spirit than the others modules. Modify some IGMP debug traces.
1533 2007-08-29 Frédéric Bernon
1534 * Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function"
1535 Add lwip_init function to regroup all modules initializations, and to provide
1536 a place to add code for task #7142 "Sanity check user-configurable values".
1537 Ports maintainers should remove direct initializations calls from their code,
1538 and add init.c in their makefiles. Note that lwip_init() function is called
1539 inside tcpip_init, but can also be used by raw api users since all calls are
1540 disabled when matching options are disabled. Also note that their is new options
1541 in opt.h, you should configure in your lwipopts.h (they are enabled per default).
1543 2007-08-26 Marc Boucher
1544 * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL
1545 since they can under certain circumstances be called with an invalid conn
1546 pointer after the connection has been closed (and conn has been freed).
1548 2007-08-25 Frédéric Bernon (Artem Migaev's Patch)
1549 * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up".
1550 Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set.
1552 2007-08-22 Frédéric Bernon
1553 * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK
1554 to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release.
1556 2007-08-22 Frédéric Bernon
1557 * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT &
1558 ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the
1559 name is tcpip_input (we keep the name of 1.2.0 function).
1561 2007-08-17 Jared Grubb
1562 * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool
1563 settings into new memp_std.h and optional user file lwippools.h. This adds
1564 more dynamic mempools, and allows the user to create an arbitrary number of
1565 mempools for mem_malloc.
1567 2007-08-16 Marc Boucher
1568 * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function;
1569 otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely
1570 close the connection.
1572 2007-08-16 Marc Boucher
1573 * sockets.c: lwip_accept(): check netconn_peer() error return.
1575 2007-08-16 Marc Boucher
1576 * mem.c, mem.h: Added mem_calloc().
1578 2007-08-16 Marc Boucher
1579 * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT)
1580 for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG
1581 and starving other message types.
1582 Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API
1584 2007-08-16 Marc Boucher
1585 * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf
1586 type and flgs (later renamed to flags).
1587 Use enum pbuf_flag as pbuf_type. Renumber PBUF_FLAG_*.
1588 Improved lwip_recvfrom(). TCP push now propagated.
1590 2007-08-16 Marc Boucher
1591 * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global
1594 2007-08-16 Marc Boucher
1595 * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h,
1596 etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c:
1597 Added PPPoE support and various PPP improvements.
1599 2007-07-25 Simon Goldschmidt
1600 * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial,
1601 making netbuf_copy_partial use this function.
1603 2007-07-25 Simon Goldschmidt
1604 * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with
1605 2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and
1608 2007-07-13 Jared Grubb (integrated by Frédéric Bernon)
1609 * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add
1610 a link callback in the netif struct, and functions to handle it. Be carefull
1611 for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c)
1612 if you want to be sure to be compatible with future changes...
1614 2007-06-30 Frédéric Bernon
1615 * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.
1617 2007-06-21 Simon Goldschmidt
1618 * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both
1619 LWIP_AUTOIP =0 and =1 to remove redundant code.
1621 2007-06-21 Simon Goldschmidt
1622 * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option
1623 MEM_USE_POOLS to use 4 pools with different sized elements instead of a
1624 heap. This both prevents memory fragmentation and gives a higher speed
1625 at the cost of more memory consumption. Turned off by default.
1627 2007-06-21 Simon Goldschmidt
1628 * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of
1629 netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into
1630 int to be able to send a bigger buffer than 64K with one time (mainly
1631 used from lwip_send).
1633 2007-06-21 Simon Goldschmidt
1634 * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write
1635 into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too.
1637 2007-06-21 Simon Goldschmidt
1638 * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in
1639 netconn_write from api_lib.c to api_msg.c to also prevent multiple context-
1640 changes on low memory or empty send-buffer.
1642 2007-06-18 Simon Goldschmidt
1643 * etharp.c, etharp.h: Changed etharp to use a defined hardware address length
1644 of 6 to avoid loading netif->hwaddr_len every time (since this file is only
1645 used for ethernet and struct eth_addr already had a defined length of 6).
1647 2007-06-17 Simon Goldschmidt
1648 * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets
1649 to disable UDP checksum generation on transmit.
1651 2007-06-13 Frédéric Bernon, Simon Goldschmidt
1652 * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid
1653 pointers or parameters, and let the possibility to redefined it in cc.h. Use
1654 this macro to check "conn" parameter in api_msg.c functions.
1656 2007-06-11 Simon Goldschmidt
1657 * sockets.c, sockets.h: Added UDP lite support for sockets
1659 2007-06-10 Simon Goldschmidt
1660 * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled
1661 by default) to switch off UDP-Lite support if not needed (reduces udp.c code
1664 2007-06-09 Dominik Spies (integrated by Frédéric Bernon)
1665 * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h:
1666 AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and
1667 LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt
1668 (see TODO mark in the source code).
1670 2007-06-09 Simon Goldschmidt
1671 * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for
1672 etharp_output() to match netif->output so etharp_output() can be used
1673 directly as netif->output to save one function call.
1675 2007-06-08 Simon Goldschmidt
1676 * netif.h, ethernetif.c, slipif.c, loopif.c: Added define
1677 NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables,
1678 added initialization of those to ethernetif, slipif and loopif.
1680 2007-05-18 Simon Goldschmidt
1681 * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF
1682 (defaulting to off for now) that can be set to 0 to send fragmented
1683 packets by passing PBUF_REFs down the stack.
1685 2007-05-23 Frédéric Bernon
1686 * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP
1687 connections, such present in patch #5959.
1689 2007-05-23 Frédéric Bernon
1690 * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx
1691 code in only one part...
1693 2007-05-18 Simon Goldschmidt
1694 * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp
1695 elements to overflow. This is achieved by adding some bytes before and after
1696 each pool element (increasing their size, of course), filling them with a
1697 prominent value and checking them on freeing the element.
1698 Set it to 2 to also check every element in every pool each time memp_malloc()
1699 or memp_free() is called (slower but more helpful).
1701 2007-05-10 Simon Goldschmidt
1702 * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for
1703 PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce
1706 2007-05-11 Frédéric Bernon
1707 * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c:
1708 Include a function pointer instead of a table index in the message to reduce
1709 footprint. Disable some part of lwip_send and lwip_sendto if some options are
1710 not set (LWIP_TCP, LWIP_UDP, LWIP_RAW).
1712 2007-05-10 Simon Goldschmidt
1713 * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus
1714 \ extern "C" {' in all header files. Now you can write your application using
1715 the lwIP stack in C++ and simply #include the core files. Note I have left
1716 out the netif/ppp/*h header files for now, since I don't know which files are
1717 included by applications and which are for internal use only.
1719 2007-05-09 Simon Goldschmidt
1720 * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library
1721 memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for
1722 situations where some compilers might inline the copy and save a function
1723 call. Also replaced all calls to memcpy() with calls to (S)MEMCPY().
1725 2007-05-08 Simon Goldschmidt
1726 * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc())
1727 to be overriden in case the C-library malloc implementation is not protected
1728 against concurrent access.
1730 2007-05-04 Simon Goldschmidt (Atte Kojo)
1731 * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending
1732 multiple packets to the same host.
1734 2007-05-04 Frédéric Bernon, Jonathan Larmour
1735 * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible
1736 to corrupt remote addr/port connection state". Reduce problems "not enought memory" with
1737 netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between
1738 sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function.
1739 Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct,
1740 these fields are now renamed "addr" & "port".
1742 2007-04-11 Jonathan Larmour
1743 * sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new
1744 sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return
1745 with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro
1746 by the port in sys_arch.h if desired.
1748 2007-04-06 Frédéric Bernon, Simon Goldschmidt
1749 * opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API
1750 allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp
1751 clients, using new functions from netifapi.h. Disable as default (no port change to do).
1753 2007-04-05 Frédéric Bernon
1754 * sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant.
1756 2007-04-04 Simon Goldschmidt
1757 * arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x)
1758 use this for and architecture-independent form to tell the compiler you intentionally
1759 are not using this variable. Can be overriden in cc.h.
1761 2007-03-28 Frédéric Bernon
1762 * opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to
1763 define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded
1764 string, point on one of your's ethernetif field, or alloc a string you will free yourself).
1765 It will be used by DHCP to register a client hostname, but can also be use when you call
1768 2007-03-28 Frédéric Bernon
1769 * netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to
1770 initialize a network interface's flag with. It tell this interface is an ethernet
1771 device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility
1772 Support for IPv4" section 4.6) when interface is "up" with netif_set_up().
1774 2007-03-26 Frédéric Bernon, Jonathan Larmour
1775 * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build
1776 time if you only use PPP or SLIP. The default is enable. Note we don't have to call
1777 etharp_init in your port's initilization sequence if you use tcpip.c, because this call
1778 is done in tcpip_init function.
1780 2007-03-22 Frédéric Bernon
1781 * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the
1782 new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in
1783 your lwipopts.h. More, unused counters are not defined in the stats structs, and not
1784 display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined
1785 but never used. Fix msg_in.c with the correct #if test for a stat display.
1787 2007-03-21 Kieran Mansley
1788 * netif.c, netif.h: Apply patch#4197 with some changes (originator: rireland@hmgsl.com).
1789 Provides callback on netif up/down state change.
1791 2007-03-11 Frédéric Bernon, Mace Gael, Steve Reynolds
1792 * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, igmp.h, igmp.c,
1793 ip.c, netif.h, tcpip.c, opt.h:
1794 New configuration option LWIP_IGMP to enable IGMP processing. Based on only one
1795 filter per all network interfaces. Declare a new function in netif to enable to
1796 control the MAC filter (to reduce lwIP traffic processing).
1798 2007-03-11 Frédéric Bernon
1799 * tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can
1800 be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this
1801 unless you know what you're doing (default are RFC1122 compliant). Note
1802 that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds.
1804 2007-03-08 Frédéric Bernon
1805 * tcp.h: Keepalive values can be configured at compile time, but don't change
1806 this unless you know what you're doing (default are RFC1122 compliant).
1808 2007-03-08 Frédéric Bernon
1809 * sockets.c, api.h, api_lib.c, tcpip.c, sys.h, sys.c, err.c, opt.h:
1810 Implement LWIP_SO_RCVTIMEO configuration option to enable/disable SO_RCVTIMEO
1811 on UDP sockets/netconn.
1813 2007-03-08 Simon Goldschmidt
1814 * snmp_msg.h, msg_in.c: SNMP UDP ports can be configured at compile time.
1816 2007-03-06 Frédéric Bernon
1817 * api.h, api_lib.c, sockets.h, sockets.c, tcpip.c, sys.h, sys.c, err.h:
1818 Implement SO_RCVTIMEO on UDP sockets/netconn.
1820 2007-02-28 Kieran Mansley (based on patch from Simon Goldschmidt)
1821 * api_lib.c, tcpip.c, memp.c, memp.h: make API msg structs allocated
1822 on the stack and remove the API msg type from memp
1824 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
1825 * sockets.h, sockets.c: Move socket initialization to new
1826 lwip_socket_init() function.
1827 NOTE: this changes the API with ports. Ports will have to be
1828 updated to call lwip_socket_init() now.
1830 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
1831 * api_lib.c: Use memcpy in netbuf_copy_partial.
1836 2008-03-17 Frédéric Bernon, Ed Kerekes
1837 * igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have
1838 some problems to fill the IP header on some targets, use now the
1839 ip.h macros to do it).
1841 2008-03-13 Frédéric Bernon
1842 * sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using
1843 (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a
1844 TCP connection caused a crash. Note that using (lwip_)recvfrom
1845 like this is a bit slow and that using (lwip)getpeername is the
1846 good lwip way to do it (so, using recv is faster on tcp sockets).
1848 2008-03-12 Frédéric Bernon, Jonathan Larmour
1849 * api_msg.c, contrib/apps/ping.c: Fix bug #22530 "api_msg.c's
1850 recv_raw() does not consume data", and the ping sample (with
1851 LWIP_SOCKET=1, the code did the wrong supposition that lwip_recvfrom
1852 returned the IP payload, without the IP header).
1854 2008-03-04 Jonathan Larmour
1855 * mem.c, stats.c, mem.h: apply patch #6414 to avoid compiler errors
1856 and/or warnings on some systems where mem_size_t and size_t differ.
1857 * pbuf.c, ppp.c: Fix warnings on some systems with mem_malloc.
1859 2008-03-04 Kieran Mansley (contributions by others)
1860 * Numerous small compiler error/warning fixes from contributions to
1861 mailing list after 1.3.0 release candidate made.
1863 2008-01-25 Cui hengbin (integrated by Frédéric Bernon)
1864 * dns.c: Fix bug #22108 "DNS problem" caused by unaligned structures.
1866 2008-01-15 Kieran Mansley
1867 * tcp_out.c: BUG20511. Modify persist timer to start when we are
1868 prevented from sending by a small send window, not just a zero
1871 2008-01-09 Jonathan Larmour
1872 * opt.h, ip.c: Rename IP_OPTIONS define to IP_OPTIONS_ALLOWED to avoid
1873 conflict with Linux system headers.
1875 2008-01-06 Jonathan Larmour
1876 * dhcp.c: fix bug #19927: "DHCP NACK problem" by clearing any existing set IP
1877 address entirely on receiving a DHCPNAK, and restarting discovery.
1879 2007-12-21 Simon Goldschmidt
1880 * sys.h, api_lib.c, api_msg.c, sockets.c: fix bug #21698: "netconn->recv_avail
1881 is not protected" by using new macros for interlocked access to modify/test
1882 netconn->recv_avail.
1884 2007-12-20 Kieran Mansley (based on patch from Oleg Tyshev)
1885 * tcp_in.c: fix bug# 21535 (nrtx not reset correctly in SYN_SENT state)
1887 2007-12-20 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
1888 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: fix bug #20199 (better handling
1889 of silly window avoidance and prevent lwIP from shrinking the window)
1891 2007-12-04 Simon Goldschmidt
1892 * tcp.c, tcp_in.c: fix bug #21699 (segment leak in ooseq processing when last
1893 data packet was lost): add assert that all segment lists are empty in
1894 tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED
1895 state from LAST_ACK in tcp_process
1897 2007-12-02 Simon Goldschmidt
1898 * sockets.h: fix bug #21654: exclude definition of struct timeval from #ifndef FD_SET
1899 If including <sys/time.h> for system-struct timeval, LWIP_TIMEVAL_PRIVATE now
1900 has to be set to 0 in lwipopts.h
1902 2007-12-02 Simon Goldschmidt
1903 * api_msg.c, api_lib.c: fix bug #21656 (recvmbox problem in netconn API): always
1904 allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen
1905 netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox.
1906 This is a fix for thread-safety and allocates all items needed for a netconn
1907 when the netconn is created.
1909 2007-11-30 Simon Goldschmidt
1910 * udp.c: first attempt to fix bug #21655 (DHCP doesn't work reliably with multiple
1911 netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed
1912 to netif->dhcp->pcb only (if that exists) and not to any other pcb for the same
1913 port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address)
1915 2007-11-27 Simon Goldschmidt
1916 * ip.c: fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by
1917 letting ip_route only use netifs that are up.
1919 2007-11-27 Simon Goldschmidt
1920 * err.h, api_lib.c, api_msg.c, sockets.c: Changed error handling: ERR_MEM, ERR_BUF
1921 and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and
1922 sockets block most operations once they have seen a fatal error.
1924 2007-11-27 Simon Goldschmidt
1925 * udp.h, udp.c, dhcp.c: Implemented new function udp_sendto_if which takes the
1926 netif to send as an argument (to be able to send on netifs that are down).
1928 2007-11-26 Simon Goldschmidt
1929 * tcp_in.c: Fixed bug #21582: pcb->acked accounting can be wrong when ACKs
1932 2007-11-21 Simon Goldschmidt
1933 * tcp.h, tcp_out.c, api_msg.c: Fixed bug #20287: tcp_output_nagle sends too early
1934 Fixed the nagle algorithm; nagle now also works for all raw API applications
1935 and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY'
1937 2007-11-12 Frédéric Bernon
1938 * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most
1939 of the netconn_peer and netconn_addr processing is done inside tcpip_thread
1940 context in do_getaddr.
1942 2007-11-10 Simon Goldschmidt
1943 * etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can
1944 happen any time). Now the packet simply isn't enqueued when out of memory.
1946 2007-11-01 Simon Goldschmidt
1947 * tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or
1948 TCP_MSS if that is smaller) as long as no MSS option is received from the
1951 2007-11-01 Simon Goldschmidt
1952 * tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN)
1953 is now based on TCP_MSS instead of pcb->mss (on passive open now effectively
1954 sending our configured TCP_MSS instead of the one received).
1956 2007-11-01 Simon Goldschmidt
1957 * tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was
1958 calculated based on the configured TCP_MSS, not on the MSS option received
1961 2007-10-09 Simon Goldschmidt
1962 * udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too
1963 short and also was generated wrong if checksum coverage != tot_len;
1964 receive: checksum was calculated wrong if checksum coverage != tot_len
1966 2007-10-08 Simon Goldschmidt
1967 * mem.c: lfree was not updated in mem_realloc!
1969 2007-10-07 Frédéric Bernon
1970 * sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential
1971 crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT:
1972 this change cause an API breakage for netconn_addr, since a parameter
1973 type change. Any compiler should cause an error without any changes in
1974 yours netconn_peer calls (so, it can't be a "silent change"). It also
1975 reduce a little bit the footprint for socket layer (lwip_getpeername &
1976 lwip_getsockname use now a common lwip_getaddrname function since
1977 netconn_peer & netconn_addr have the same parameters).
1979 2007-09-20 Simon Goldschmidt
1980 * tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state)
1981 by checking tcp_tw_pcbs also
1983 2007-09-19 Simon Goldschmidt
1984 * icmp.c: Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies)
1986 2007-09-15 Mike Kleshov
1987 * mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used)
1989 2007-09-06 Frédéric Bernon
1990 * several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove
1991 it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which
1992 already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h"
1993 if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h.
1995 2007-08-30 Frédéric Bernon
1996 * igmp.h, igmp.c: Some changes to remove some redundant code, add some traces,
1997 and fix some coding style.
1999 2007-08-28 Frédéric Bernon
2000 * tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any
2001 kind of packets. These packets are considered like Ethernet packets (payload
2002 pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets
2003 are considered like IP packets (payload pointing to iphdr).
2005 2007-08-27 Frédéric Bernon
2006 * api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error
2007 problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state
2008 and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT).
2010 2007-08-24 Kieran Mansley
2011 * inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy
2012 compiler (Paradigm C++)
2014 2007-08-09 Frédéric Bernon, Bill Florac
2015 * stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement.
2016 Introduce IGMP_STATS to centralize statistics management.
2018 2007-08-09 Frédéric Bernon, Bill Florac
2019 * udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast
2020 packet on a udp pcb binded on an netif's IP address, and not on "any".
2022 2007-08-09 Frédéric Bernon, Bill Florac
2023 * igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement.
2024 This is mainly on using lookup/lookfor, and some coding styles...
2026 2007-07-26 Frédéric Bernon (and "thedoctor")
2027 * igmp.c: Fix bug #20595 to accept IGMPv3 "Query" messages.
2029 2007-07-25 Simon Goldschmidt
2030 * api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if
2031 tcp_output fails in tcp_close, the code in do_close_internal gets simpler
2032 (tcp_output is called again later from tcp timers).
2034 2007-07-25 Simon Goldschmidt
2035 * ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old
2036 copy_from_pbuf, which illegally modified the given pbuf.
2038 2007-07-25 Simon Goldschmidt
2039 * tcp_out.c: tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs:
2040 changed snd_queuelen++ to snd_queuelen += pbuf_clen(p).
2042 2007-07-24 Simon Goldschmidt
2043 * api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the
2044 correct state (must be CLOSED).
2046 2007-07-13 Thomas Taranowski (commited by Jared Grubb)
2047 * memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed
2048 allocation. It now returns NULL.
2050 2007-07-13 Frédéric Bernon
2051 * api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in
2054 2007-07-13 Frédéric Bernon
2055 * api_msg.c: Fix bug #20315: possible memory leak problem if tcp_listen failed,
2056 because current code doesn't follow rawapi.txt documentation.
2058 2007-07-13 Kieran Mansley
2059 * src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in
2060 out of sequence processing of received packets
2062 2007-07-03 Simon Goldschmidt
2063 * nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an
2064 assumption is made that this pbuf is in one piece (i.e. not chained). These
2065 assumptions clash with the possibility of converting to fully pool-based
2066 pbuf implementations, where PBUF_RAM pbufs might be chained.
2068 2007-07-03 Simon Goldschmidt
2069 * api.h, api_lib.c, api_msg.c: Final fix for bug #20021 and some other problems
2070 when closing tcp netconns: removed conn->sem, less context switches when
2071 closing, both netconn_close and netconn_delete should safely close tcp
2074 2007-07-02 Simon Goldschmidt
2075 * ipv4/ip.h, ipv6/ip.h, opt.h, netif.h, etharp.h, ipv4/ip.c, netif.c, raw.c,
2076 tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off)
2077 to cache ARP table indices with each pcb instead of single-entry cache for
2080 2007-07-02 Simon Goldschmidt
2081 * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent
2082 warnings when assigning to smaller types.
2084 2007-06-28 Simon Goldschmidt
2085 * tcp_out.c: Added check to prevent tcp_pcb->snd_queuelen from overflowing.
2087 2007-06-28 Simon Goldschmidt
2088 * tcp.h: Fixed bug #20287: Fixed nagle algorithm (sending was done too early if
2089 a segment contained chained pbufs)
2091 2007-06-28 Frédéric Bernon
2092 * autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute
2093 a "pseudo-random" value based on netif's MAC and some autoip fields. It's always
2094 possible to define this macro in your own lwipopts.h to always use C library's
2095 rand(). Note that autoip_create_rand_addr doesn't use this macro.
2097 2007-06-28 Frédéric Bernon
2098 * netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option
2099 LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications
2100 in api_lib/api_msg (use pointers and not type with table, etc...)
2102 2007-06-26 Simon Goldschmidt
2103 * udp.h: Fixed bug #20259: struct udp_hdr was lacking the packin defines.
2105 2007-06-25 Simon Goldschmidt
2106 * udp.c: Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload
2107 for udp packets with no matching pcb.
2109 2007-06-25 Simon Goldschmidt
2110 * udp.c: Fixed bug #20220: UDP PCB search in udp_input(): a non-local match
2111 could get udp input packets if the remote side matched.
2113 2007-06-13 Simon Goldschmidt
2114 * netif.c: Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get
2115 changed in netif_set_ipaddr if previous netif->ip_addr.addr was 0.
2117 2007-06-13 Simon Goldschmidt
2118 * api_msg.c: pcb_new sets conn->err if protocol is not implemented
2119 -> netconn_new_..() does not allocate a new connection for unsupported
2122 2007-06-13 Frédéric Bernon, Simon Goldschmidt
2123 * api_lib.c: change return expression in netconn_addr and netconn_peer, because
2124 conn->err was reset to ERR_OK without any reasons (and error was lost)...
2126 2007-06-13 Frédéric Bernon, Matthias Weisser
2127 * opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename
2128 MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid
2129 some macro names collision with some OS macros.
2131 2007-06-11 Simon Goldschmidt
2132 * udp.c: UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0,
2133 create checksum over the complete packet. On RX, if it's < 8 (and not 0),
2134 discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both
2137 2007-06-11 Srinivas Gollakota & Oleg Tyshev
2138 * tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP flags"
2139 where TCP flags wasn't initialized in tcp_keepalive.
2141 2007-06-03 Simon Goldschmidt
2142 * udp.c: udp_input(): Input pbuf was not freed if pcb had no recv function
2143 registered, p->payload was modified without modifying p->len if sending
2144 icmp_dest_unreach() (had no negative effect but was definitively wrong).
2146 2007-06-03 Simon Goldschmidt
2147 * icmp.c: Corrected bug #19937: For responding to an icmp echo request, icmp
2148 re-used the input pbuf even if that didn't have enough space to include the
2149 link headers. Now the space is tested and a new pbuf is allocated for the
2150 echo response packet if the echo request pbuf isn't big enough.
2152 2007-06-01 Simon Goldschmidt
2153 * sockets.c: Checked in patch #5914: Moved sockopt processing into tcpip_thread.
2155 2007-05-23 Frédéric Bernon
2156 * api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only
2157 allocated by do_listen if success) and netconn_accept errors handling. In
2158 most of api_lib functions, we replace some errors checkings like "if (conn==NULL)"
2159 by ASSERT, except for netconn_delete.
2161 2007-05-23 Frédéric Bernon
2162 * api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return
2163 an error code if it's impossible to fetch a pbuf on a TCP connection (and not
2164 directly close the recvmbox).
2166 2007-05-22 Simon Goldschmidt
2167 * tcp.c: Fixed bug #1895 (tcp_bind not correct) by introducing a list of
2168 bound but unconnected (and non-listening) tcp_pcbs.
2170 2007-05-22 Frédéric Bernon
2171 * sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only
2172 used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of
2173 sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features
2174 like "sys_timeout" in their application threads.
2176 2007-05-22 Frédéric Bernon
2177 * api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see
2178 which parameters are used by which do_xxx function, and to avoid "misusing"
2179 parameters (patch #5938).
2181 2007-05-22 Simon Goldschmidt
2182 * api_lib.c, api_msg.c, raw.c, api.h, api_msg.h, raw.h: Included patch #5938:
2183 changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto
2184 is only 8 bits wide. This affects the api, as there, the protocol was
2187 2007-05-18 Simon Goldschmidt
2188 * memp.c: addition to patch #5913: smaller pointer was returned but
2189 memp_memory was the same size -> did not save memory.
2191 2007-05-16 Simon Goldschmidt
2192 * loopif.c, slipif.c: Fix bug #19729: free pbuf if netif->input() returns
2195 2007-05-16 Simon Goldschmidt
2196 * api_msg.c, udp.c: If a udp_pcb has a local_ip set, check if it is the same
2197 as the one of the netif used for sending to prevent sending from old
2198 addresses after a netif address gets changed (partly fixes bug #3168).
2200 2007-05-16 Frédéric Bernon
2201 * tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work
2202 with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in
2203 tcpip_init) because we have to be sure that network interfaces are already
2204 added (mac filter is updated only in igmp_init for the moment).
2206 2007-05-16 Simon Goldschmidt
2207 * mem.c, memp.c: Removed semaphores from memp, changed sys_sem_wait calls
2208 into sys_arch_sem_wait calls to prevent timers from running while waiting
2209 for the heap. This fixes bug #19167.
2211 2007-05-13 Simon Goldschmidt
2212 * tcp.h, sockets.h, sockets.c: Fixed bug from patch #5865 by moving the defines
2213 for socket options (lwip_set/-getsockopt) used with level IPPROTO_TCP from
2216 2007-05-07 Simon Goldschmidt
2217 * mem.c: Another attempt to fix bug #17922.
2219 2007-05-04 Simon Goldschmidt
2220 * pbuf.c, pbuf.h, etharp.c: Further update to ARP queueing: Changed pbuf_copy()
2221 implementation so that it can be reused (don't allocate the target
2222 pbuf inside pbuf_copy()).
2224 2007-05-04 Simon Goldschmidt
2225 * memp.c: checked in patch #5913: in memp_malloc() we can return memp as mem
2226 to save a little RAM (next pointer of memp is not used while not in pool).
2229 * sockets.c: Fix ioctl FIONREAD when some data remains from last recv.
2232 2007-04-23 Simon Goldschmidt
2233 * loopif.c, loopif.h, opt.h, src/netif/FILES: fix bug #2595: "loopif results
2234 in NULL reference for incoming TCP packets". Loopif has to be configured
2235 (using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input()
2236 (multithreading environments, e.g. netif->input() = tcpip_input()) or
2237 putting packets on a list that is fed to the stack by calling loopif_poll()
2238 (single-thread / NO_SYS / polling environment where e.g.
2239 netif->input() = ip_input).
2241 2007-04-17 Jonathan Larmour
2242 * pbuf.c: Use s32_t in pbuf_realloc(), as an s16_t can't reliably hold
2243 the difference between two u16_t's.
2244 * sockets.h: FD_SETSIZE needs to match number of sockets, which is
2245 MEMP_NUM_NETCONN in sockets.c right now.
2247 2007-04-12 Jonathan Larmour
2248 * icmp.c: Reset IP header TTL in ICMP ECHO responses (bug #19580).
2250 2007-04-12 Kieran Mansley
2251 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Modify way the retransmission
2252 timer is reset to fix bug#19434, with help from Oleg Tyshev.
2254 2007-04-11 Simon Goldschmidt
2255 * etharp.c, pbuf.c, pbuf.h: 3rd fix for bug #11400 (arp-queuing): More pbufs than
2256 previously thought need to be copied (everything but PBUF_ROM!). Cleaned up
2257 pbuf.c: removed functions no needed any more (by etharp).
2259 2007-04-11 Kieran Mansley
2260 * inet.c, ip_addr.h, sockets.h, sys.h, tcp.h: Apply patch #5745: Fix
2261 "Constant is long" warnings with 16bit compilers. Contributed by
2262 avatar@mmlab.cse.yzu.edu.tw
2264 2007-04-05 Frédéric Bernon, Jonathan Larmour
2265 * api_msg.c: Fix bug #16830: "err_tcp() posts to connection mailbox when no pend on
2266 the mailbox is active". Now, the post is only done during a connect, and do_send,
2267 do_write and do_join_leave_group don't do anything if a previous error was signaled.
2269 2007-04-03 Frédéric Bernon
2270 * ip.c: Don't set the IP_DF ("Don't fragment") flag in the IP header in IP output
2271 packets. See patch #5834.
2273 2007-03-30 Frédéric Bernon
2274 * api_msg.c: add a "pcb_new" helper function to avoid redundant code, and to add
2275 missing pcb allocations checking (in do_bind, and for each raw_new). Fix style.
2277 2007-03-30 Frédéric Bernon
2278 * most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with
2279 others environment defines (these were too "generic").
2281 2007-03-28 Frédéric Bernon
2282 * api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal pbuf_alloc call
2283 result and can cause a crash. lwip_send now check netbuf_ref result.
2285 2007-03-28 Simon Goldschmidt
2286 * sockets.c Remove "#include <errno.h>" from sockets.c to avoid multiple
2287 definition of macros (in errno.h and lwip/arch.h) if LWIP_PROVIDE_ERRNO is
2288 defined. This is the way it should have been already (looking at
2291 2007-03-28 Kieran Mansley
2292 * opt.h Change default PBUF_POOL_BUFSIZE (again) to accomodate default MSS +
2293 IP and TCP headers *and* physical link headers
2295 2007-03-26 Frédéric Bernon (based on patch from Dmitry Potapov)
2296 * api_lib.c: patch for netconn_write(), fixes a possible race condition which cause
2297 to send some garbage. It is not a definitive solution, but the patch does solve
2298 the problem for most cases.
2300 2007-03-22 Frédéric Bernon
2301 * api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used).
2303 2007-03-22 Frédéric Bernon
2304 * api_lib.c: somes resources couldn't be freed if there was errors during
2305 netconn_new_with_proto_and_callback.
2307 2007-03-22 Frédéric Bernon
2308 * ethernetif.c: update netif->input calls to check return value. In older ports,
2309 it's a good idea to upgrade them, even if before, there could be another problem
2310 (access to an uninitialized mailbox).
2312 2007-03-21 Simon Goldschmidt
2313 * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed
2314 by casting to unsigned).
2316 2007-03-21 Frédéric Bernon
2317 * api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from
2318 api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a
2319 dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call.
2320 Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a
2321 faster and more reliable communication between api_lib and tcpip.
2323 2007-03-21 Frédéric Bernon
2324 * opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0.
2326 2007-03-21 Frédéric Bernon
2327 * api_msg.c, igmp.c, igmp.h: Fix C++ style comments
2329 2007-03-21 Kieran Mansley
2330 * opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS +
2333 2007-03-21 Kieran Mansley
2334 * Fix all uses of pbuf_header to check the return value. In some
2335 cases just assert if it fails as I'm not sure how to fix them, but
2336 this is no worse than before when they would carry on regardless
2339 2007-03-21 Kieran Mansley
2340 * sockets.c, igmp.c, igmp.h, memp.h: Fix C++ style comments and
2341 comment out missing header include in icmp.c
2343 2007-03-20 Frédéric Bernon
2344 * memp.h, stats.c: Fix stats_display function where memp_names table wasn't
2345 synchronized with memp.h.
2347 2007-03-20 Frédéric Bernon
2348 * tcpip.c: Initialize tcpip's mbox, and verify if initialized in tcpip_input,
2349 tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init problem with
2350 network interfaces. Also fix a compiler warning.
2352 2007-03-20 Kieran Mansley
2353 * udp.c: Only try and use pbuf_header() to make space for headers if
2354 not a ROM or REF pbuf.
2356 2007-03-19 Frédéric Bernon
2357 * api_msg.h, api_msg.c, tcpip.h, tcpip.c: Add return types to tcpip_apimsg()
2360 2007-03-19 Frédéric Bernon
2361 * Remove unimplemented "memp_realloc" function from memp.h.
2363 2007-03-11 Simon Goldschmidt
2364 * pbuf.c: checked in patch #5796: pbuf_alloc: len field claculation caused
2367 2007-03-11 Simon Goldschmidt (based on patch from Dmitry Potapov)
2368 * api_lib.c, sockets.c, api.h, api_msg.h, sockets.h: Fixed bug #19251
2369 (missing `const' qualifier in socket functions), to get more compatible to
2370 standard POSIX sockets.
2372 2007-03-11 Frédéric Bernon (based on patch from Dmitry Potapov)
2373 * sockets.c: Add asserts inside bind, connect and sendto to check input
2374 parameters. Remove excessive set_errno() calls after get_socket(), because
2375 errno is set inside of get_socket(). Move last sock_set_errno() inside
2378 2007-03-09 Simon Goldschmidt
2379 * memp.c: Fixed bug #11400: New etharp queueing introduced bug: memp_memory
2380 was allocated too small.
2382 2007-03-06 Simon Goldschmidt
2383 * tcpip.c: Initialize dhcp timers in tcpip_thread (if LWIP_DHCP) to protect
2384 the stack from concurrent access.
2386 2007-03-06 Frédéric Bernon, Dmitry Potapov
2387 * tcpip.c, ip_frag.c, ethernetif.c: Fix some build problems, and a redundancy
2388 call to "lwip_stats.link.recv++;" in low_level_input() & ethernetif_input().
2390 2007-03-06 Simon Goldschmidt
2391 * ip_frag.c, ip_frag.h: Reduce code size: don't include code in those files
2392 if IP_FRAG == 0 and IP_REASSEMBLY == 0
2394 2007-03-06 Frédéric Bernon, Simon Goldschmidt
2395 * opt.h, ip_frag.h, tcpip.h, tcpip.c, ethernetif.c: add new configuration
2396 option named ETHARP_TCPIP_ETHINPUT, which enable the new tcpip_ethinput.
2397 Allow to do ARP processing for incoming packets inside tcpip_thread
2398 (protecting ARP layer against concurrent access). You can also disable
2399 old code using tcp_input with new define ETHARP_TCPIP_INPUT set to 0.
2400 Older ports have to use tcpip_ethinput.
2402 2007-03-06 Simon Goldschmidt (based on patch from Dmitry Potapov)
2403 * err.h, err.c: fixed compiler warning "initialization dircards qualifiers
2404 from pointer target type"
2406 2007-03-05 Frédéric Bernon
2407 * opt.h, sockets.h: add new configuration options (LWIP_POSIX_SOCKETS_IO_NAMES,
2408 ETHARP_TRUST_IP_MAC, review SO_REUSE)
2410 2007-03-04 Frédéric Bernon
2411 * api_msg.c: Remove some compiler warnings : parameter "pcb" was never
2414 2007-03-04 Frédéric Bernon
2415 * api_lib.c: Fix "[patch #5764] api_lib.c cleanup: after patch #5687" (from
2417 The api_msg struct stay on the stack (not moved to netconn struct).
2419 2007-03-04 Simon Goldschmidt (based on patch from Dmitry Potapov)
2420 * pbuf.c: Fix BUG#19168 - pbuf_free can cause deadlock (if
2421 SYS_LIGHTWEIGHT_PROT=1 & freeing PBUF_RAM when mem_sem is not available)
2422 Also fixed cast warning in pbuf_alloc()
2424 2007-03-04 Simon Goldschmidt
2425 * etharp.c, etharp.h, memp.c, memp.h, opt.h: Fix BUG#11400 - don't corrupt
2426 existing pbuf chain when enqueuing multiple pbufs to a pending ARP request
2428 2007-03-03 Frédéric Bernon
2429 * udp.c: remove obsolete line "static struct udp_pcb *pcb_cache = NULL;"
2430 It is static, and never used in udp.c except udp_init().
2432 2007-03-02 Simon Goldschmidt
2433 * tcpip.c: Moved call to ip_init(), udp_init() and tcp_init() from
2434 tcpip_thread() to tcpip_init(). This way, raw API connections can be
2435 initialized before tcpip_thread is running (e.g. before OS is started)
2437 2007-03-02 Frédéric Bernon
2438 * rawapi.txt: Fix documentation mismatch with etharp.h about etharp_tmr's call
2441 2007-02-28 Kieran Mansley
2442 * pbuf.c: Fix BUG#17645 - ensure pbuf payload pointer is not moved
2443 outside the region of the pbuf by pbuf_header()
2445 2007-02-28 Kieran Mansley
2446 * sockets.c: Fix BUG#19161 - ensure milliseconds timeout is non-zero
2447 when supplied timeout is also non-zero
2451 2006-12-05 Leon Woestenberg
2452 * CHANGELOG: Mention STABLE-1.2.0 release.
2456 2006-12-01 Christiaan Simons
2457 * mem.h, opt.h: Added MEM_LIBC_MALLOC option.
2458 Note this is a workaround. Currently I have no other options left.
2460 2006-10-26 Christiaan Simons (accepted patch by Jonathan Larmour)
2461 * ipv4/ip_frag.c: rename MAX_MTU to IP_FRAG_MAX_MTU and move define
2462 to include/lwip/opt.h.
2463 * ipv4/lwip/ip_frag.h: Remove unused IP_REASS_INTERVAL.
2464 Move IP_REASS_MAXAGE and IP_REASS_BUFSIZE to include/lwip/opt.h.
2465 * opt.h: Add above new options.
2467 2006-08-18 Christiaan Simons
2468 * tcp_{in,out}.c: added SNMP counters.
2469 * ipv4/ip.c: added SNMP counters.
2470 * ipv4/ip_frag.c: added SNMP counters.
2472 2006-08-08 Christiaan Simons
2473 * etharp.{c,h}: added etharp_find_addr() to read
2474 (stable) ethernet/IP address pair from ARP table
2476 2006-07-14 Christiaan Simons
2477 * mib_structs.c: added
2478 * include/lwip/snmp_structs.h: added
2479 * netif.{c,h}, netif/ethernetif.c: added SNMP statistics to netif struct
2481 2006-07-06 Christiaan Simons
2482 * snmp/asn1_{enc,dec}.c added
2484 * snmp/msg_{in,out}.c added
2485 * include/lwip/snmp_asn1.h added
2486 * include/lwip/snmp_msg.h added
2487 * doc/snmp_agent.txt added
2489 2006-03-29 Christiaan Simons
2490 * inet.c, inet.h: Added platform byteswap support.
2491 Added LWIP_PLATFORM_BYTESWAP define (defaults to 0) and
2492 optional LWIP_PLATFORM_HTONS(), LWIP_PLATFORM_HTONL() macros.
2496 2006-11-30 Christiaan Simons
2497 * dhcp.c: Fixed false triggers of request_timeout.
2499 2006-11-28 Christiaan Simons
2500 * netif.c: In netif_add() fixed missing clear of ip_addr, netmask, gw and flags.
2502 2006-10-11 Christiaan Simons
2503 * api_lib.c etharp.c, ip.c, memp.c, stats.c, sys.{c,h} tcp.h:
2504 Partially accepted patch #5449 for ANSI C compatibility / build fixes.
2505 * ipv4/lwip/ip.h ipv6/lwip/ip.h: Corrected UDP-Lite protocol
2506 identifier from 170 to 136 (bug #17574).
2508 2006-10-10 Christiaan Simons
2509 * api_msg.c: Fixed Nagle algorithm as reported by Bob Grice.
2511 2006-08-17 Christiaan Simons
2512 * udp.c: Fixed bug #17200, added check for broadcast
2513 destinations for PCBs bound to a unicast address.
2515 2006-08-07 Christiaan Simons
2516 * api_msg.c: Flushing TCP output in do_close() (bug #15926).
2518 2006-06-27 Christiaan Simons
2519 * api_msg.c: Applied patch for cold case (bug #11135).
2520 In accept_function() ensure newconn->callback is always initialized.
2522 2006-06-15 Christiaan Simons
2523 * mem.h: added MEM_SIZE_F alias to fix an ancient cold case (bug #1748),
2524 facilitate printing of mem_size_t and u16_t statistics.
2526 2006-06-14 Christiaan Simons
2527 * api_msg.c: Applied patch #5146 to handle allocation failures
2528 in accept() by Kevin Lawson.
2530 2006-05-26 Christiaan Simons
2531 * api_lib.c: Removed conn->sem creation and destruction
2532 from netconn_write() and added sys_sem_new to netconn_new_*.
2536 2006-03-03 Christiaan Simons
2537 * ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap
2538 access and added pbuf_alloc() return value checks.
2540 2006-01-01 Leon Woestenberg <leon.woestenberg@gmx.net>
2541 * tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is
2542 now handled by the checksum routine properly.
2544 2006-02-27 Leon Woestenberg <leon.woestenberg@gmx.net>
2545 * pbuf.c: Fix alignment; pbuf_init() would not work unless
2546 pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.)
2548 2005-12-20 Leon Woestenberg <leon.woestenberg@gmx.net>
2549 * tcp.c: Remove PCBs which stay in LAST_ACK state too long. Patch
2550 submitted by Mitrani Hiroshi.
2552 2005-12-15 Christiaan Simons
2553 * inet.c: Disabled the added summing routine to preserve code space.
2555 2005-12-14 Leon Woestenberg <leon.woestenberg@gmx.net>
2556 * tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
2557 Added Curt McDowell's optimized checksumming routine for future
2558 inclusion. Need to create test case for unaliged, aligned, odd,
2559 even length combination of cases on various endianess machines.
2561 2005-12-09 Christiaan Simons
2562 * inet.c: Rewrote standard checksum routine in proper portable C.
2564 2005-11-25 Christiaan Simons
2565 * udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
2566 * *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
2567 u32_t, s32_t typedefs. This solves most debug word-length assumes.
2569 2005-07-17 Leon Woestenberg <leon.woestenberg@gmx.net>
2570 * inet.c: Fixed unaligned 16-bit access in the standard checksum
2571 routine by Peter Jolasson.
2572 * slipif.c: Fixed implementation assumption of single-pbuf datagrams.
2574 2005-02-04 Leon Woestenberg <leon.woestenberg@gmx.net>
2575 * tcp_out.c: Fixed uninitialized 'queue' referenced in memerr branch.
2576 * tcp_{out|in}.c: Applied patch fixing unaligned access.
2578 2005-01-04 Leon Woestenberg <leon.woestenberg@gmx.net>
2579 * pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement.
2581 2005-01-03 Leon Woestenberg <leon.woestenberg@gmx.net>
2582 * udp.c: UDP pcb->recv() was called even when it was NULL.
2586 2004-12-28 Leon Woestenberg <leon.woestenberg@gmx.net>
2587 * etharp.*: Disabled multiple packets on the ARP queue.
2588 This clashes with TCP queueing.
2590 2004-11-28 Leon Woestenberg <leon.woestenberg@gmx.net>
2591 * etharp.*: Fixed race condition from ARP request to ARP timeout.
2592 Halved the ARP period, doubled the period counts.
2593 ETHARP_MAX_PENDING now should be at least 2. This prevents
2594 the counter from reaching 0 right away (which would allow
2595 too little time for ARP responses to be received).
2597 2004-11-25 Leon Woestenberg <leon.woestenberg@gmx.net>
2598 * dhcp.c: Decline messages were not multicast but unicast.
2599 * etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
2600 Do not try hard to insert arbitrary packet's source address,
2601 etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
2602 etharp_query() now always DOES call ETHARP_TRY_HARD so that users
2603 querying an address will see it appear in the cache (DHCP could
2604 suffer from this when a server invalidly gave an in-use address.)
2605 * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
2606 comparing network addresses (identifiers), not the network masks
2608 * ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
2609 IP address actually belongs to the network of the given interface.
2611 2004-11-24 Kieran Mansley <kjm25@cam.ac.uk>
2612 * tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.
2616 2004-10-16 Kieran Mansley <kjm25@cam.ac.uk>
2617 * tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
2618 even if one is already pending, if the rcv_wnd is above a threshold
2619 (currently TCP_WND/2). This avoids waiting for a timer to expire to send a
2620 delayed ACK in order to open the window if the stack is only receiving data.
2622 2004-09-12 Kieran Mansley <kjm25@cam.ac.uk>
2623 * tcp*.*: Retransmit time-out handling improvement by Sam Jansen.
2625 2004-08-20 Tony Mountifield <tony@softins.co.uk>
2626 * etharp.c: Make sure the first pbuf queued on an ARP entry
2627 is properly ref counted.
2629 2004-07-27 Tony Mountifield <tony@softins.co.uk>
2630 * debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
2631 warnings about comparison.
2632 * pbuf.c: Stopped compiler complaining of empty if statement
2633 when LWIP_DEBUGF() empty. Closed an unclosed comment.
2634 * tcp.c: Stopped compiler complaining of empty if statement
2635 when LWIP_DEBUGF() empty.
2636 * ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
2637 * inet.c: Added a couple of casts to quiet the compiler.
2638 No need to test isascii(c) before isdigit(c) or isxdigit(c).
2640 2004-07-22 Tony Mountifield <tony@softins.co.uk>
2641 * inet.c: Made data types consistent in inet_ntoa().
2642 Added casts for return values of checksum routines, to pacify compiler.
2643 * ip_frag.c, tcp_out.c, sockets.c, pbuf.c
2644 Small corrections to some debugging statements, to pacify compiler.
2646 2004-07-21 Tony Mountifield <tony@softins.co.uk>
2647 * etharp.c: Removed spurious semicolon and added missing end-of-comment.
2648 * ethernetif.c Updated low_level_output() to match prototype for
2649 netif->linkoutput and changed low_level_input() similarly for consistency.
2650 * api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
2651 of raw_recv() in raw.h and so avoid compiler error.
2652 * sockets.c: Added trivial (int) cast to keep compiler happier.
2653 * ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.
2659 2004-07-05 Leon Woestenberg <leon.woestenberg@gmx.net>
2660 * sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure
2661 your cc.h file defines this either 1 or 0. If non-defined,
2663 * .c: Added <string.h> and <errno.h> includes where used.
2664 * etharp.c: Made some array indices unsigned.
2666 2004-06-27 Leon Woestenberg <leon.woestenberg@gmx.net>
2667 * netif.*: Added netif_set_up()/down().
2668 * dhcp.c: Changes to restart program flow.
2670 2004-05-07 Leon Woestenberg <leon.woestenberg@gmx.net>
2671 * etharp.c: In find_entry(), instead of a list traversal per candidate, do a
2672 single-pass lookup for different candidates. Should exploit locality.
2674 2004-04-29 Leon Woestenberg <leon.woestenberg@gmx.net>
2675 * tcp*.c: Cleaned up source comment documentation for Doxygen processing.
2676 * opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC.
2677 * etharp.c: update_arp_entry() only adds new ARP entries when adviced to by
2678 the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option.
2682 2004-04-27 Leon Woestenberg <leon.woestenberg@gmx.net>
2683 * etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution
2684 suggested by Timmy Brolin. Fix for 32-bit processors that cannot access
2685 non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix
2686 is to prefix the 14-bit Ethernet headers with two padding bytes.
2688 2004-04-23 Leon Woestenberg <leon.woestenberg@gmx.net>
2689 * ip_addr.c: Fix in the ip_addr_isbroadcast() check.
2690 * etharp.c: Fixed the case where the packet that initiates the ARP request
2691 is not queued, and gets lost. Fixed the case where the packets destination
2692 address is already known; we now always queue the packet and perform an ARP
2699 * Fixed TCP bug for SYN_SENT to ESTABLISHED state transition.
2700 * Fixed TCP bug in dequeueing of FIN from out of order segment queue.
2701 * Fixed two possible NULL references in rare cases.
2707 * Fixed DHCP which did not include the IP address in DECLINE messages.
2711 * etharp.c has been hauled over a bit.
2717 * Fixed TCP bug induced by bad window resizing with unidirectional TCP traffic.
2718 * Packets sent from ARP queue had invalid source hardware address.
2722 * Pass-by ARP requests do now update the cache.
2726 * No longer dependent on ctype.h.
2727 * New socket options.
2728 * Raw IP pcb support.
2734 * Some debug formatters and casts fixed.
2735 * Numereous fixes in PPP.
2739 * DEBUGF now is LWIP_DEBUGF
2740 * pbuf_dechain() has been re-enabled.
2741 * Mentioned the changed use of CVS branches in README.
2747 * Fixed pool pbuf memory leak in pbuf_alloc().
2748 Occured if not enough PBUF_POOL pbufs for a packet pbuf chain.
2749 Reported by Savin Zlobec.
2751 * PBUF_POOL chains had their tot_len field not set for non-first
2752 pbufs. Fixed in pbuf_alloc().
2756 * Added PPP stack contributed by Marc Boucher
2760 * Now drops short packets for ICMP/UDP/TCP protocols. More robust.
2762 * ARP queueuing now queues the latest packet instead of the first.
2763 This is the RFC recommended behaviour, but can be overridden in
2770 * TCP has been fixed to deal with the new use of the pbuf->ref
2773 * DHCP dhcp_inform() crash bug fixed.
2777 * Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
2778 pbuf_refresh(). This has sped up pbuf pool operations considerably.
2779 Implemented by David Haas.
2785 * The packet buffer implementation has been enhanced to support
2786 zero-copy and copy-on-demand for packet buffers which have their
2787 payloads in application-managed memory.
2788 Implemented by David Haas.
2790 Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
2791 if an outgoing packet can be directly sent on the link, or perform
2792 a copy-on-demand when necessary.
2794 The application can safely assume the packet is sent, and the RAM
2795 is available to the application directly after calling udp_send()
2796 or similar function.
2800 * ARP_QUEUEING should now correctly work for all cases, including
2802 Implemented by Leon Woestenberg.
2806 * IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
2807 to a '0.0.0.0' IP address.
2809 * The packet buffer implementation is changed. The pbuf->ref counter
2810 meaning has changed, and several pbuf functions have been
2811 adapted accordingly.
2813 * netif drivers have to be changed to set the hardware address length field
2814 that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).
2815 See the contrib/ports/c16x cs8900 driver as a driver example.
2817 * netif's have a dhcp field that must be initialized to NULL by the driver.
2818 See the contrib/ports/c16x cs8900 driver as a driver example.
2820 (0.5.x) This file has been unmaintained up to 0.6.1. All changes are
2821 logged in CVS but have not been explained here.
2823 (0.5.3) Changes since version 0.5.2
2827 * memp_malloc(MEMP_API_MSG) could fail with multiple application
2828 threads because it wasn't protected by semaphores.
2832 * struct ip_addr now packed.
2834 * The name of the time variable in arp.c has been changed to ctime
2835 to avoid conflicts with the time() function.
2837 (0.5.2) Changes since version 0.5.1
2841 * A new TCP function, tcp_tmr(), now handles both TCP timers.
2845 * A bug in tcp_parseopt() could cause the stack to hang because of a
2846 malformed TCP option.
2848 * The address of new connections in the accept() function in the BSD
2849 socket library was not handled correctly.
2851 * pbuf_dechain() did not update the ->tot_len field of the tail.
2853 * Aborted TCP connections were not handled correctly in all
2858 * All protocol header structs are now packed.
2860 * The ->len field in the tcp_seg structure now counts the actual
2861 amount of data, and does not add one for SYN and FIN segments.
2863 (0.5.1) Changes since version 0.5.0
2867 * Possible to run as a user process under Linux.
2869 * Preliminary support for cross platform packed structs.
2871 * ARP timer now implemented.
2875 * TCP output queue length was badly initialized when opening
2878 * TCP delayed ACKs were not sent correctly.
2880 * Explicit initialization of BSS segment variables.
2882 * read() in BSD socket library could drop data.
2884 * Problems with memory alignment.
2886 * Situations when all TCP buffers were used could lead to
2889 * TCP MSS option wasn't parsed correctly.
2891 * Problems with UDP checksum calculation.
2893 * IP multicast address tests had endianess problems.
2895 * ARP requests had wrong destination hardware address.
2899 * struct eth_addr changed from u16_t[3] array to u8_t[6].
2901 * A ->linkoutput() member was added to struct netif.
2903 * TCP and UDP ->dest_* struct members where changed to ->remote_*.
2905 * ntoh* macros are now null definitions for big endian CPUs.
2907 (0.5.0) Changes since version 0.4.2
2911 * Redesigned operating system emulation layer to make porting easier.
2913 * Better control over TCP output buffers.
2915 * Documenation added.
2919 * Locking issues in buffer management.
2921 * Bugfixes in the sequential API.
2923 * IP forwarding could cause memory leakage. This has been fixed.
2927 * Directory structure somewhat changed; the core/ tree has been
2930 (0.4.2) Changes since version 0.4.1
2934 * Experimental ARP implementation added.
2936 * Skeleton Ethernet driver added.
2938 * Experimental BSD socket API library added.
2942 * In very intense situations, memory leakage could occur. This has
2947 * Variables named "data" and "code" have been renamed in order to
2948 avoid name conflicts in certain compilers.
2950 * Variable++ have in appliciable cases been translated to ++variable
2951 since some compilers generate better code in the latter case.
2953 (0.4.1) Changes since version 0.4
2957 * TCP: Connection attempts time out earlier than data
2958 transmissions. Nagle algorithm implemented. Push flag set on the
2959 last segment in a burst.
2961 * UDP: experimental support for UDP-Lite extensions.
2965 * TCP: out of order segments were in some cases handled incorrectly,
2966 and this has now been fixed. Delayed acknowledgements was broken
2967 in 0.4, has now been fixed. Binding to an address that is in use
2968 now results in an error. Reset connections sometimes hung an
2969 application; this has been fixed.
2971 * Checksum calculation sometimes failed for chained pbufs with odd
2972 lengths. This has been fixed.
2974 * API: a lot of bug fixes in the API. The UDP API has been improved
2975 and tested. Error reporting and handling has been
2976 improved. Logical flaws and race conditions for incoming TCP
2977 connections has been found and removed.
2979 * Memory manager: alignment issues. Reallocating memory sometimes
2980 failed, this has been fixed.
2982 * Generic library: bcopy was flawed and has been fixed.
2986 * API: all datatypes has been changed from generic ones such as
2987 ints, to specified ones such as u16_t. Functions that return
2988 errors now have the correct type (err_t).
2990 * General: A lot of code cleaned up and debugging code removed. Many
2991 portability issues have been fixed.
2993 * The license was changed; the advertising clause was removed.
2997 * Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri
2998 Kosunen, Mikael Caleres, and Frits Wilmink for reporting and
3001 (0.4) Changes since version 0.3.1
3003 * Memory management has been radically changed; instead of
3004 allocating memory from a shared heap, memory for objects that are
3005 rapidly allocated and deallocated is now kept in pools. Allocation
3006 and deallocation from those memory pools is very fast. The shared
3007 heap is still present but is used less frequently.
3009 * The memory, memory pool, and packet buffer subsystems now support
3010 4-, 2-, or 1-byte alignment.
3012 * "Out of memory" situations are handled in a more robust way.
3014 * Stack usage has been reduced.
3016 * Easier configuration of lwIP parameters such as memory usage,
3017 TTLs, statistics gathering, etc. All configuration parameters are
3018 now kept in a single header file "lwipopts.h".
3020 * The directory structure has been changed slightly so that all
3021 architecture specific files are kept under the src/arch
3024 * Error propagation has been improved, both in the protocol modules
3027 * The code for the RTXC architecture has been implemented, tested
3030 * Bugs have been found and corrected in the TCP, UDP, IP, API, and
3031 the Internet checksum modules.
3033 * Bugs related to porting between a 32-bit and a 16-bit architecture
3034 have been found and corrected.
3036 * The license has been changed slightly to conform more with the
3037 original BSD license, including the advertisement clause.
3039 (0.3.1) Changes since version 0.3
3041 * Fix of a fatal bug in the buffer management. Pbufs with allocated
3042 RAM never returned the RAM when the pbuf was deallocated.
3044 * TCP congestion control, window updates and retransmissions did not
3045 work correctly. This has now been fixed.
3047 * Bugfixes in the API.
3049 (0.3) Changes since version 0.2
3051 * New and improved directory structure. All include files are now
3052 kept in a dedicated include/ directory.
3054 * The API now has proper error handling. A new function,
3055 netconn_err(), now returns an error code for the connection in
3058 * Improvements in the memory management subsystem. The system now
3059 keeps a pointer to the lowest free memory block. A new function,
3060 mem_malloc2() tries to allocate memory once, and if it fails tries
3061 to free some memory and retry the allocation.
3063 * Much testing has been done with limited memory
3064 configurations. lwIP now does a better job when overloaded.
3066 * Some bugfixes and improvements to the buffer (pbuf) subsystem.
3068 * Many bugfixes in the TCP code:
3070 - Fixed a bug in tcp_close().
3072 - The TCP receive window was incorrectly closed when out of
3073 sequence segments was received. This has been fixed.
3075 - Connections are now timed-out of the FIN-WAIT-2 state.
3077 - The initial congestion window could in some cases be too
3078 large. This has been fixed.
3080 - The retransmission queue could in some cases be screwed up. This
3083 - TCP RST flag now handled correctly.
3085 - Out of sequence data was in some cases never delivered to the
3086 application. This has been fixed.
3088 - Retransmitted segments now contain the correct acknowledgment
3089 number and advertised window.
3091 - TCP retransmission timeout backoffs are not correctly computed
3092 (ala BSD). After a number of retransmissions, TCP now gives up
3095 * TCP connections now are kept on three lists, one for active
3096 connections, one for listening connections, and one for
3097 connections that are in TIME-WAIT. This greatly speeds up the fast
3098 timeout processing for sending delayed ACKs.
3100 * TCP now provides proper feedback to the application when a
3101 connection has been successfully set up.
3103 * More comments have been added to the code. The code has also been
3104 somewhat cleaned up.
3106 (0.2) Initial public release.
