elessair	0:f269e3021894	29	* Cleanup TCPIP thread sync methods in a way that it is possibe to use them
elessair	0:f269e3021894	30	in arbitrary code that needs things to be done in TCPIP thread. Used to
elessair	0:f269e3021894	31	decouple netconn, netif, ppp and 6LoWPAN from LWIP core.
elessair	0:f269e3021894	32

elessair	0:f269e3021894	45	2015-11-12: Dirk Ziegelmeier
elessair	0:f269e3021894	46	* Implement possibility to declare private memory pools. This is useful to
elessair	0:f269e3021894	47	decouple some apps from the core (SNMP stack) or make contrib app usage
elessair	0:f269e3021894	48	simpler (httpserver_raw)
elessair	0:f269e3021894	49
elessair	0:f269e3021894	50	2015-10-09: Simon Goldschmidt
elessair	0:f269e3021894	51	* started to move "private" header files containing implementation details to

elessair	0:f269e3021894	59	* snmp_structs.h, mib_structs.c, mib2.c: snmp: fixed ugly inheritance
elessair	0:f269e3021894	60	implementation by aggregating the "base class" (struct mib_node) in all
elessair	0:f269e3021894	61	derived node classes to get more type-safe code
elessair	0:f269e3021894	62
elessair	0:f269e3021894	63	2015-09-23: Simon Goldschmidt

elessair	0:f269e3021894	66
elessair	0:f269e3021894	67	2015-09-08: Dirk Ziegelmeier
elessair	0:f269e3021894	68	* snmp: Separate mib2 counter/table callbacks from snmp agent. This both cleans
elessair	0:f269e3021894	69	up the code and should allow integration of a 3rd party agent/mib2. Simple
elessair	0:f269e3021894	70	counters are kept in MIB2_STATS, tree/table change function prototypes moved to
elessair	0:f269e3021894	71	snmp_mib2.h.

elessair	0:f269e3021894	102	ip_addr_t to ip4_addr_t, renamed ipX_addr_t to ip_addr_t and added IP
elessair	0:f269e3021894	103	version; ip_addr_t is used for all generic IP addresses for the API,
elessair	0:f269e3021894	104	ip(4/6)_addr_t are only used internally or when initializing netifs or when
elessair	0:f269e3021894	105	calling version-related functions
elessair	0:f269e3021894	106
elessair	0:f269e3021894	107	2015-03-24: Simon Goldschmidt

elessair	0:f269e3021894	250	* New PPP stack for lwIP, developed in ppp-new branch.
elessair	0:f269e3021894	251	Based from pppd 2.4.5, released 2009-11-17, with huge changes to match
elessair	0:f269e3021894	252	code size and memory requirements for embedded devices, including:
elessair	0:f269e3021894	253	- Gluing together the previous low-level PPP code in lwIP to pppd 2.4.5, which
elessair	0:f269e3021894	254	is more or less what pppd sys-* files are, so that we get something working
elessair	0:f269e3021894	255	using the unix port.
elessair	0:f269e3021894	256	- Merged some patchs from lwIP Git repository which add interesting features
elessair	0:f269e3021894	257	or fix bugs.
elessair	0:f269e3021894	258	- Merged some patchs from Debian pppd package which add interesting features
elessair	0:f269e3021894	259	or fix bugs.
elessair	0:f269e3021894	260	- Ported PPP timeout handling to the lwIP timers system
elessair	0:f269e3021894	261	- Disabled all the PPP code using filesystem access, replaced in necessary cases
elessair	0:f269e3021894	262	to configuration variables.
elessair	0:f269e3021894	263	- Disabled all the PPP code forking processes.
elessair	0:f269e3021894	264	- Removed IPX support, lwIP does not support IPX.
elessair	0:f269e3021894	265	- Ported and improved random module from the previous PPP port.
elessair	0:f269e3021894	266	- Removed samba TDB (file-driven database) usage, because it needs a filesystem.
elessair	0:f269e3021894	267	- MS-CHAP required a DES implementation, we added the latest PolarSSL DES
elessair	0:f269e3021894	268	implementation which is under a BSD-ish license.
elessair	0:f269e3021894	269	- Also switched to PolarSSL MD4,MD5,SHA1 implementations, which are meant to be
elessair	0:f269e3021894	270	used in embedded devices with reduced memory footprint.
elessair	0:f269e3021894	271	- Removed PPP configuration file parsing support.
elessair	0:f269e3021894	272	- Added macro definition EAP_SUPPORT to make EAP support optional.

elessair	0:f269e3021894	277	- Disabled demand support using a macro, so that it can be ported later.
elessair	0:f269e3021894	278	- Disabled ECP support using a macro, so that it can be ported later.
elessair	0:f269e3021894	279	- Disabled CCP support using a macro, so that it can be ported later.
elessair	0:f269e3021894	280	- Disabled CBCP support using a macro, so that it can be ported later.
elessair	0:f269e3021894	281	- Disabled LQR support using a macro, so that it can be ported later.
elessair	0:f269e3021894	282	- Print packet debug feature optional, through PRINTPKT_SUPPORT
elessair	0:f269e3021894	283	- Removed POSIX signal usage.
elessair	0:f269e3021894	284	- Fully ported PPPoS code from the previous port.
elessair	0:f269e3021894	285	- Fully ported PPPoE code from the previous port.
elessair	0:f269e3021894	286	- Fully ported VJ compression protocol code from the previous port.
elessair	0:f269e3021894	287	- Removed all malloc()/free() use from PPP, replaced by stack usage or PBUF.
elessair	0:f269e3021894	288	- Disabled PPP server support using a macro, so that it can be ported later.
elessair	0:f269e3021894	289	- Switched all PPP debug to lwIP debug system.
elessair	0:f269e3021894	290	- Created PPP Control Block (PPP PCB), removed PPP unit integer everywhere,
elessair	0:f269e3021894	291	removed all global variables everywhere, did everything necessary for
elessair	0:f269e3021894	292	the PPP stack to support more than one PPP session (pppd only support
elessair	0:f269e3021894	293	one session per process).
elessair	0:f269e3021894	294	- Removed the statically allocated output buffer, now using PBUF.
elessair	0:f269e3021894	295	- Improved structure size of all PPP modules, deep analyze of code to reduce
elessair	0:f269e3021894	296	variables size to the bare minimum. Switched all boolean type (char type in
elessair	0:f269e3021894	297	most architecture) to compiler generated bitfields.
elessair	0:f269e3021894	298	- Added PPP IPv6 support, glued lwIP IPv6 support to PPP.
elessair	0:f269e3021894	299	- Now using a persistent netif interface which can then be used in lwIP
elessair	0:f269e3021894	300	functions requiring a netif.
elessair	0:f269e3021894	301	- Now initializing PPP in lwip_init() function.
elessair	0:f269e3021894	302	- Reworked completely the PPP state machine, so that we don't end up in
elessair	0:f269e3021894	303	anymore in inconsistent state, especially with PPPoE.
elessair	0:f269e3021894	304	- Improved the way we handle PPP reconnection after disconnect, cleaning
elessair	0:f269e3021894	305	everything required so that we start the PPP connection again from a
elessair	0:f269e3021894	306	clean state.
elessair	0:f269e3021894	307	- Added PPP holdoff support, allow the lwIP user to wait a little bit before
elessair	0:f269e3021894	308	reconnecting, prevents connection flood, especially when using PPPoL2TP.
elessair	0:f269e3021894	309	- Added PPPoL2TP LAC support (a.k.a. UDP tunnels), adding a VPN client
elessair	0:f269e3021894	310	feature to lwIP, L2TP being a widely used tunnel protocol.
elessair	0:f269e3021894	311	- Switched all used PPP types to lwIP types (u8t, u16t, u32t, ...)
elessair	0:f269e3021894	312	- Added PPP API "sequential" thread-safe API, based from NETIFAPI.

elessair	0:f269e3021894	320	combined ipv4/ipv6 inet_chksum.c, added ip.h, ip_addr.h: Combined IPv4
elessair	0:f269e3021894	321	and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP
elessair	0:f269e3021894	322	code so that the code is more readable.

elessair	0:f269e3021894	2402	* api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential
elessair	0:f269e3021894	2403	dns resolver function for netconn api (netconn_gethostbyname) and socket api
elessair	0:f269e3021894	2404	(gethostbyname/gethostbyname_r).

elessair	0:f269e3021894	2408	requests with RAW api interface. Initialization is done in lwip_init() with
elessair	0:f269e3021894	2409	build time options. DNS timer is added in tcpip_thread context. DHCP can set
elessair	0:f269e3021894	2410	DNS server ip addresses when options are received. You need to set LWIP_DNS=1
elessair	0:f269e3021894	2411	in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get
elessair	0:f269e3021894	2412	some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo"
elessair	0:f269e3021894	2413	list with points to improve.

elessair	0:f269e3021894	2416	* opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly
elessair	0:f269e3021894	2417	enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status
elessair	0:f269e3021894	2418	for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.

elessair	0:f269e3021894	2421	* api.h, api_msg.h and dependent files: Task #7410: Removed the need to include
elessair	0:f269e3021894	2422	core header files in api.h (ip/tcp/udp/raw.h) to hide the internal
elessair	0:f269e3021894	2423	implementation from netconn api applications.

elessair	0:f269e3021894	2425	2007-11-03 Frédéric Bernon
elessair	0:f269e3021894	2426	* api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP &
elessair	0:f269e3021894	2427	RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled
elessair	0:f269e3021894	2428	by default). Netconn API users can use the netconn_recv_bufsize macro to access
elessair	0:f269e3021894	2429	it. This is a first release which have to be improve for TCP. Note it used the
elessair	0:f269e3021894	2430	netconn::recv_avail which need to be more "thread-safe" (note there is already
elessair	0:f269e3021894	2431	the problem for FIONREAD with lwip_ioctl/ioctlsocket).

elessair	0:f269e3021894	2435	Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api
elessair	0:f269e3021894	2436	layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api
elessair	0:f269e3021894	2437	layer. This option enable to delayed TCP PUSH flag on multiple "write" calls.
elessair	0:f269e3021894	2438	Note that previous "copy" parameter for "write" APIs is now called "apiflags".

elessair	0:f269e3021894	2441	* api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than
elessair	0:f269e3021894	2442	TCP_EVENT_xxx macros to get a code more readable. It could also help to remove
elessair	0:f269e3021894	2443	some code (like we have talk in "patch #5919 : Create compile switch to remove
elessair	0:f269e3021894	2444	select code"), but it could be done later.

elessair	0:f269e3021894	2446	2007-10-08 Simon Goldschmidt
elessair	0:f269e3021894	2447	* many files: Changed initialization: many init functions are not needed any
elessair	0:f269e3021894	2448	more since we now rely on the compiler initializing global and static
elessair	0:f269e3021894	2449	variables to zero!

elessair	0:f269e3021894	2451	2007-10-06 Simon Goldschmidt
elessair	0:f269e3021894	2452	* ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY
elessair	0:f269e3021894	2453	to enqueue the received pbufs so that multiple packets can be reassembled
elessair	0:f269e3021894	2454	simultaneously and no static reassembly buffer is needed.

elessair	0:f269e3021894	2457	* tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so
elessair	0:f269e3021894	2458	all netifs (or ports) can use it.
elessair	0:f269e3021894	2459
elessair	0:f269e3021894	2460	2007-10-05 Frédéric Bernon
elessair	0:f269e3021894	2461	* netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the
elessair	0:f269e3021894	2462	common function to reduce a little bit the footprint (for all functions using
elessair	0:f269e3021894	2463	only the "netif" parameter).

elessair	0:f269e3021894	2465	2007-10-03 Frédéric Bernon
elessair	0:f269e3021894	2466	* netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down,
elessair	0:f269e3021894	2467	netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce
elessair	0:f269e3021894	2468	a little bit the footprint (for all functions using only the "netif" parameter).

elessair	0:f269e3021894	2470	2007-09-15 Frédéric Bernon
elessair	0:f269e3021894	2471	* udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF
elessair	0:f269e3021894	2472	option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for
elessair	0:f269e3021894	2473	netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for
elessair	0:f269e3021894	2474	IP_MULTICAST_TTL and IP_MULTICAST_IF.
elessair	0:f269e3021894	2475
elessair	0:f269e3021894	2476	2007-09-10 Frédéric Bernon
elessair	0:f269e3021894	2477	* snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles
elessair	0:f269e3021894	2478	even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime()
elessair	0:f269e3021894	2479	each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can
elessair	0:f269e3021894	2480	decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but
elessair	0:f269e3021894	2481	call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime()
elessair	0:f269e3021894	2482	or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
elessair	0:f269e3021894	2483	This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
elessair	0:f269e3021894	2484	snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
elessair	0:f269e3021894	2485	when it's queried (any direct call to "sysuptime" is changed by a call to
elessair	0:f269e3021894	2486	snmp_get_sysuptime).

elessair	0:f269e3021894	2489	* igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP,
elessair	0:f269e3021894	2490	and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags
elessair	0:f269e3021894	2491	if you want IGMP on an interface. igmp_stop() is now called inside netif_remove().
elessair	0:f269e3021894	2492	igmp_report_groups() is now called inside netif_set_link_up() (need to have
elessair	0:f269e3021894	2493	LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait

elessair	0:f269e3021894	2498	IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change).
elessair	0:f269e3021894	2499	Use this new field to access to common pcb fields (ttl, tos, so_options, etc...).

elessair	0:f269e3021894	2504	ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option
elessair	0:f269e3021894	2505	LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default).
elessair	0:f269e3021894	2506	Be careful, disabling ICMP make your product non-compliant to RFC1122, but

elessair	0:f269e3021894	2512	parameters have to be provided: a task name, and a task stack size. For this
elessair	0:f269e3021894	2513	one, since it's platform dependant, you could define the best one for you in
elessair	0:f269e3021894	2514	your lwipopts.h. For port maintainers, you can just add these new parameters
elessair	0:f269e3021894	2515	in your sys_arch.c file, and but it's not mandatory, use them in your OS

elessair	0:f269e3021894	2531	* igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement".
elessair	0:f269e3021894	2532	Initialize igmp_mac_filter to NULL in netif_add (this field should be set in
elessair	0:f269e3021894	2533	the netif's "init" function). Use the "imr_interface" field (for socket layer)
elessair	0:f269e3021894	2534	and/or the "interface" field (for netconn layer), for join/leave operations.
elessair	0:f269e3021894	2535	The igmp_join/leavegroup first parameter change from a netif to an ipaddr.
elessair	0:f269e3021894	2536	This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany).

elessair	0:f269e3021894	2538	2007-08-30 Frédéric Bernon
elessair	0:f269e3021894	2539	* Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions
elessair	0:f269e3021894	2540	from api/api_lib". Now netbuf API is independant of netconn, and can be used
elessair	0:f269e3021894	2541	with other API (application based on raw API, or future "socket2" API). Ports
elessair	0:f269e3021894	2542	maintainers just have to add src/api/netbuf.c in their makefile/projects.

elessair	0:f269e3021894	2555	Add lwip_init function to regroup all modules initializations, and to provide
elessair	0:f269e3021894	2556	a place to add code for task #7142 "Sanity check user-configurable values".
elessair	0:f269e3021894	2557	Ports maintainers should remove direct initializations calls from their code,
elessair	0:f269e3021894	2558	and add init.c in their makefiles. Note that lwip_init() function is called
elessair	0:f269e3021894	2559	inside tcpip_init, but can also be used by raw api users since all calls are
elessair	0:f269e3021894	2560	disabled when matching options are disabled. Also note that their is new options
elessair	0:f269e3021894	2561	in opt.h, you should configure in your lwipopts.h (they are enabled per default).

elessair	0:f269e3021894	2637	2007-06-21 Simon Goldschmidt
elessair	0:f269e3021894	2638	* etharp.h, etharp.c: Combined etharp_request with etharp_raw for both
elessair	0:f269e3021894	2639	LWIP_AUTOIP =0 and =1 to remove redundant code.
elessair	0:f269e3021894	2640
elessair	0:f269e3021894	2641	2007-06-21 Simon Goldschmidt
elessair	0:f269e3021894	2642	* mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option
elessair	0:f269e3021894	2643	MEM_USE_POOLS to use 4 pools with different sized elements instead of a
elessair	0:f269e3021894	2644	heap. This both prevents memory fragmentation and gives a higher speed
elessair	0:f269e3021894	2645	at the cost of more memory consumption. Turned off by default.

elessair	0:f269e3021894	2647	2007-06-21 Simon Goldschmidt
elessair	0:f269e3021894	2648	* api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of
elessair	0:f269e3021894	2649	netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into
elessair	0:f269e3021894	2650	int to be able to send a bigger buffer than 64K with one time (mainly

elessair	0:f269e3021894	2653	2007-06-21 Simon Goldschmidt
elessair	0:f269e3021894	2654	* tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write
elessair	0:f269e3021894	2655	into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too.

elessair	0:f269e3021894	2663	* etharp.c, etharp.h: Changed etharp to use a defined hardware address length
elessair	0:f269e3021894	2664	of 6 to avoid loading netif->hwaddr_len every time (since this file is only
elessair	0:f269e3021894	2665	used for ethernet and struct eth_addr already had a defined length of 6).
elessair	0:f269e3021894	2666
elessair	0:f269e3021894	2667	2007-06-17 Simon Goldschmidt
elessair	0:f269e3021894	2668	* sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets

elessair	0:f269e3021894	2672	* debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid
elessair	0:f269e3021894	2673	pointers or parameters, and let the possibility to redefined it in cc.h. Use
elessair	0:f269e3021894	2674	this macro to check "conn" parameter in api_msg.c functions.

elessair	0:f269e3021894	2691	* etharp.h, etharp.c, ethernetif.c: Modified order of parameters for
elessair	0:f269e3021894	2692	etharp_output() to match netif->output so etharp_output() can be used
elessair	0:f269e3021894	2693	directly as netif->output to save one function call.

elessair	0:f269e3021894	2713	2007-05-18 Simon Goldschmidt
elessair	0:f269e3021894	2714	* opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp
elessair	0:f269e3021894	2715	elements to overflow. This is achieved by adding some bytes before and after
elessair	0:f269e3021894	2716	each pool element (increasing their size, of course), filling them with a
elessair	0:f269e3021894	2717	prominent value and checking them on freeing the element.
elessair	0:f269e3021894	2718	Set it to 2 to also check every element in every pool each time memp_malloc()

elessair	0:f269e3021894	2727	* sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c:
elessair	0:f269e3021894	2728	Include a function pointer instead of a table index in the message to reduce
elessair	0:f269e3021894	2729	footprint. Disable some part of lwip_send and lwip_sendto if some options are
elessair	0:f269e3021894	2730	not set (LWIP_TCP, LWIP_UDP, LWIP_RAW).

elessair	0:f269e3021894	2732	2007-05-10 Simon Goldschmidt
elessair	0:f269e3021894	2733	* .h (except netif/ppp/.h): Included patch #5448: include '#ifdef __cplusplus
elessair	0:f269e3021894	2734	\ extern "C" {' in all header files. Now you can write your application using
elessair	0:f269e3021894	2735	the lwIP stack in C++ and simply #include the core files. Note I have left
elessair	0:f269e3021894	2736	out the netif/ppp/*h header files for now, since I don't know which files are
elessair	0:f269e3021894	2737	included by applications and which are for internal use only.

elessair	0:f269e3021894	2740	* opt.h, .c/.h: Included patch #5920: Create define to override C-library
elessair	0:f269e3021894	2741	memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for
elessair	0:f269e3021894	2742	situations where some compilers might inline the copy and save a function
elessair	0:f269e3021894	2743	call. Also replaced all calls to memcpy() with calls to (S)MEMCPY().

elessair	0:f269e3021894	2745	2007-05-08 Simon Goldschmidt
elessair	0:f269e3021894	2746	* mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc())
elessair	0:f269e3021894	2747	to be overriden in case the C-library malloc implementation is not protected

elessair	0:f269e3021894	2755	* sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible
elessair	0:f269e3021894	2756	to corrupt remote addr/port connection state". Reduce problems "not enought memory" with
elessair	0:f269e3021894	2757	netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between
elessair	0:f269e3021894	2758	sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function.
elessair	0:f269e3021894	2759	Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct,
elessair	0:f269e3021894	2760	these fields are now renamed "addr" & "port".

elessair	0:f269e3021894	2763	* sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new
elessair	0:f269e3021894	2764	sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return
elessair	0:f269e3021894	2765	with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro
elessair	0:f269e3021894	2766	by the port in sys_arch.h if desired.

elessair	0:f269e3021894	2769	* opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API
elessair	0:f269e3021894	2770	allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp
elessair	0:f269e3021894	2771	clients, using new functions from netifapi.h. Disable as default (no port change to do).

elessair	0:f269e3021894	2776	2007-04-04 Simon Goldschmidt
elessair	0:f269e3021894	2777	* arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x)
elessair	0:f269e3021894	2778	use this for and architecture-independent form to tell the compiler you intentionally
elessair	0:f269e3021894	2779	are not using this variable. Can be overriden in cc.h.

elessair	0:f269e3021894	2782	* opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to
elessair	0:f269e3021894	2783	define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded
elessair	0:f269e3021894	2784	string, point on one of your's ethernetif field, or alloc a string you will free yourself).
elessair	0:f269e3021894	2785	It will be used by DHCP to register a client hostname, but can also be use when you call

elessair	0:f269e3021894	2789	* netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to
elessair	0:f269e3021894	2790	initialize a network interface's flag with. It tell this interface is an ethernet
elessair	0:f269e3021894	2791	device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility
elessair	0:f269e3021894	2792	Support for IPv4" section 4.6) when interface is "up" with netif_set_up().

elessair	0:f269e3021894	2795	* opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build
elessair	0:f269e3021894	2796	time if you only use PPP or SLIP. The default is enable. Note we don't have to call
elessair	0:f269e3021894	2797	etharp_init in your port's initilization sequence if you use tcpip.c, because this call
elessair	0:f269e3021894	2798	is done in tcpip_init function.

elessair	0:f269e3021894	2800	2007-03-22 Frédéric Bernon
elessair	0:f269e3021894	2801	* stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the
elessair	0:f269e3021894	2802	new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in
elessair	0:f269e3021894	2803	your lwipopts.h. More, unused counters are not defined in the stats structs, and not
elessair	0:f269e3021894	2804	display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined
elessair	0:f269e3021894	2805	but never used. Fix msg_in.c with the correct #if test for a stat display.

elessair	0:f269e3021894	2813	ip.c, netif.h, tcpip.c, opt.h:
elessair	0:f269e3021894	2814	New configuration option LWIP_IGMP to enable IGMP processing. Based on only one
elessair	0:f269e3021894	2815	filter per all network interfaces. Declare a new function in netif to enable to

elessair	0:f269e3021894	2866	good lwip way to do it (so, using recv is faster on tcp sockets).

elessair	0:f269e3021894	2924	allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen
elessair	0:f269e3021894	2925	netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox.
elessair	0:f269e3021894	2926	This is a fix for thread-safety and allocates all items needed for a netconn
elessair	0:f269e3021894	2927	when the netconn is created.

elessair	0:f269e3021894	2929	2007-11-30 Simon Goldschmidt
elessair	0:f269e3021894	2930	* udp.c: first attempt to fix bug #21655 (DHCP doesn't work reliably with multiple
elessair	0:f269e3021894	2931	netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed
elessair	0:f269e3021894	2932	to netif->dhcp->pcb only (if that exists) and not to any other pcb for the same
elessair	0:f269e3021894	2933	port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address)
elessair	0:f269e3021894	2934
elessair	0:f269e3021894	2935	2007-11-27 Simon Goldschmidt
elessair	0:f269e3021894	2936	* ip.c: fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by
elessair	0:f269e3021894	2937	letting ip_route only use netifs that are up.
elessair	0:f269e3021894	2938
elessair	0:f269e3021894	2939	2007-11-27 Simon Goldschmidt
elessair	0:f269e3021894	2940	* err.h, api_lib.c, api_msg.c, sockets.c: Changed error handling: ERR_MEM, ERR_BUF
elessair	0:f269e3021894	2941	and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and
elessair	0:f269e3021894	2942	sockets block most operations once they have seen a fatal error.
elessair	0:f269e3021894	2943
elessair	0:f269e3021894	2944	2007-11-27 Simon Goldschmidt
elessair	0:f269e3021894	2945	* udp.h, udp.c, dhcp.c: Implemented new function udp_sendto_if which takes the
elessair	0:f269e3021894	2946	netif to send as an argument (to be able to send on netifs that are down).
elessair	0:f269e3021894	2947
elessair	0:f269e3021894	2948	2007-11-26 Simon Goldschmidt
elessair	0:f269e3021894	2949	* tcp_in.c: Fixed bug #21582: pcb->acked accounting can be wrong when ACKs
elessair	0:f269e3021894	2950	arrive out-of-order
elessair	0:f269e3021894	2951
elessair	0:f269e3021894	2952	2007-11-21 Simon Goldschmidt
elessair	0:f269e3021894	2953	* tcp.h, tcp_out.c, api_msg.c: Fixed bug #20287: tcp_output_nagle sends too early
elessair	0:f269e3021894	2954	Fixed the nagle algorithm; nagle now also works for all raw API applications
elessair	0:f269e3021894	2955	and has to be explicitly disabled with 'tcp_pcb->flags \|= TF_NODELAY'
elessair	0:f269e3021894	2956
elessair	0:f269e3021894	2957	2007-11-12 Frédéric Bernon
elessair	0:f269e3021894	2958	* sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most
elessair	0:f269e3021894	2959	of the netconn_peer and netconn_addr processing is done inside tcpip_thread
elessair	0:f269e3021894	2960	context in do_getaddr.
elessair	0:f269e3021894	2961
elessair	0:f269e3021894	2962	2007-11-10 Simon Goldschmidt
elessair	0:f269e3021894	2963	* etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can
elessair	0:f269e3021894	2964	happen any time). Now the packet simply isn't enqueued when out of memory.
elessair	0:f269e3021894	2965
elessair	0:f269e3021894	2966	2007-11-01 Simon Goldschmidt
elessair	0:f269e3021894	2967	* tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or
elessair	0:f269e3021894	2968	TCP_MSS if that is smaller) as long as no MSS option is received from the
elessair	0:f269e3021894	2969	remote host.

elessair	0:f269e3021894	2971	2007-11-01 Simon Goldschmidt
elessair	0:f269e3021894	2972	* tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN)
elessair	0:f269e3021894	2973	is now based on TCP_MSS instead of pcb->mss (on passive open now effectively
elessair	0:f269e3021894	2974	sending our configured TCP_MSS instead of the one received).
elessair	0:f269e3021894	2975
elessair	0:f269e3021894	2976	2007-11-01 Simon Goldschmidt
elessair	0:f269e3021894	2977	* tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was
elessair	0:f269e3021894	2978	calculated based on the configured TCP_MSS, not on the MSS option received
elessair	0:f269e3021894	2979	with SYN+ACK.
elessair	0:f269e3021894	2980
elessair	0:f269e3021894	2981	2007-10-09 Simon Goldschmidt
elessair	0:f269e3021894	2982	* udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too
elessair	0:f269e3021894	2983	short and also was generated wrong if checksum coverage != tot_len;
elessair	0:f269e3021894	2984	receive: checksum was calculated wrong if checksum coverage != tot_len
elessair	0:f269e3021894	2985
elessair	0:f269e3021894	2986	2007-10-08 Simon Goldschmidt
elessair	0:f269e3021894	2987	* mem.c: lfree was not updated in mem_realloc!

elessair	0:f269e3021894	2989	2007-10-07 Frédéric Bernon
elessair	0:f269e3021894	2990	* sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential
elessair	0:f269e3021894	2991	crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT:
elessair	0:f269e3021894	2992	this change cause an API breakage for netconn_addr, since a parameter
elessair	0:f269e3021894	2993	type change. Any compiler should cause an error without any changes in
elessair	0:f269e3021894	2994	yours netconn_peer calls (so, it can't be a "silent change"). It also
elessair	0:f269e3021894	2995	reduce a little bit the footprint for socket layer (lwip_getpeername &
elessair	0:f269e3021894	2996	lwip_getsockname use now a common lwip_getaddrname function since
elessair	0:f269e3021894	2997	netconn_peer & netconn_addr have the same parameters).

elessair	0:f269e3021894	2999	2007-09-20 Simon Goldschmidt
elessair	0:f269e3021894	3000	* tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state)
elessair	0:f269e3021894	3001	by checking tcp_tw_pcbs also
elessair	0:f269e3021894	3002
elessair	0:f269e3021894	3003	2007-09-19 Simon Goldschmidt
elessair	0:f269e3021894	3004	* icmp.c: Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies)
elessair	0:f269e3021894	3005
elessair	0:f269e3021894	3006	2007-09-15 Mike Kleshov
elessair	0:f269e3021894	3007	* mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used)
elessair	0:f269e3021894	3008
elessair	0:f269e3021894	3009	2007-09-06 Frédéric Bernon
elessair	0:f269e3021894	3010	* several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove
elessair	0:f269e3021894	3011	it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which
elessair	0:f269e3021894	3012	already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h"
elessair	0:f269e3021894	3013	if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h.

elessair	0:f269e3021894	3015	2007-08-30 Frédéric Bernon
elessair	0:f269e3021894	3016	* igmp.h, igmp.c: Some changes to remove some redundant code, add some traces,
elessair	0:f269e3021894	3017	and fix some coding style.
elessair	0:f269e3021894	3018
elessair	0:f269e3021894	3019	2007-08-28 Frédéric Bernon
elessair	0:f269e3021894	3020	* tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any
elessair	0:f269e3021894	3021	kind of packets. These packets are considered like Ethernet packets (payload
elessair	0:f269e3021894	3022	pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets
elessair	0:f269e3021894	3023	are considered like IP packets (payload pointing to iphdr).

elessair	0:f269e3021894	3025	2007-08-27 Frédéric Bernon
elessair	0:f269e3021894	3026	* api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error
elessair	0:f269e3021894	3027	problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state
elessair	0:f269e3021894	3028	and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT).

elessair	0:f269e3021894	3030	2007-08-24 Kieran Mansley
elessair	0:f269e3021894	3031	* inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy

elessair	0:f269e3021894	3035	* stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement.
elessair	0:f269e3021894	3036	Introduce IGMP_STATS to centralize statistics management.

elessair	0:f269e3021894	3039	* udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast
elessair	0:f269e3021894	3040	packet on a udp pcb binded on an netif's IP address, and not on "any".

elessair	0:f269e3021894	3043	* igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement.
elessair	0:f269e3021894	3044	This is mainly on using lookup/lookfor, and some coding styles...

elessair	0:f269e3021894	3049	2007-07-25 Simon Goldschmidt
elessair	0:f269e3021894	3050	* api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if
elessair	0:f269e3021894	3051	tcp_output fails in tcp_close, the code in do_close_internal gets simpler
elessair	0:f269e3021894	3052	(tcp_output is called again later from tcp timers).

elessair	0:f269e3021894	3055	* ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old
elessair	0:f269e3021894	3056	copy_from_pbuf, which illegally modified the given pbuf.

elessair	0:f269e3021894	3062	2007-07-24 Simon Goldschmidt
elessair	0:f269e3021894	3063	* api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the

elessair	0:f269e3021894	3067	* memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed

elessair	0:f269e3021894	3081
elessair	0:f269e3021894	3082	2007-07-03 Simon Goldschmidt
elessair	0:f269e3021894	3083	* nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an
elessair	0:f269e3021894	3084	assumption is made that this pbuf is in one piece (i.e. not chained). These
elessair	0:f269e3021894	3085	assumptions clash with the possibility of converting to fully pool-based
elessair	0:f269e3021894	3086	pbuf implementations, where PBUF_RAM pbufs might be chained.

elessair	0:f269e3021894	3090	when closing tcp netconns: removed conn->sem, less context switches when
elessair	0:f269e3021894	3091	closing, both netconn_close and netconn_delete should safely close tcp

elessair	0:f269e3021894	3096	tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off)
elessair	0:f269e3021894	3097	to cache ARP table indices with each pcb instead of single-entry cache for

elessair	0:f269e3021894	3112	* autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute
elessair	0:f269e3021894	3113	a "pseudo-random" value based on netif's MAC and some autoip fields. It's always
elessair	0:f269e3021894	3114	possible to define this macro in your own lwipopts.h to always use C library's

elessair	0:f269e3021894	3328	* ethernetif.c: update netif->input calls to check return value. In older ports,
elessair	0:f269e3021894	3329	it's a good idea to upgrade them, even if before, there could be another problem
elessair	0:f269e3021894	3330	(access to an uninitialized mailbox).

elessair	0:f269e3021894	3337	* api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from
elessair	0:f269e3021894	3338	api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a
elessair	0:f269e3021894	3339	dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call.
elessair	0:f269e3021894	3340	Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a

elessair	0:f269e3021894	3355	cases just assert if it fails as I'm not sure how to fix them, but
elessair	0:f269e3021894	3356	this is no worse than before when they would carry on regardless

elessair	0:f269e3021894	3577	Added Curt McDowell's optimized checksumming routine for future

elessair	0:f269e3021894	3586	* *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
elessair	0:f269e3021894	3587	u32_t, s32_t typedefs. This solves most debug word-length assumes.

elessair	0:f269e3021894	3612	Halved the ARP period, doubled the period counts.
elessair	0:f269e3021894	3613	ETHARP_MAX_PENDING now should be at least 2. This prevents
elessair	0:f269e3021894	3614	the counter from reaching 0 right away (which would allow
elessair	0:f269e3021894	3615	too little time for ARP responses to be received).

elessair	0:f269e3021894	3619	* etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
elessair	0:f269e3021894	3620	Do not try hard to insert arbitrary packet's source address,
elessair	0:f269e3021894	3621	etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
elessair	0:f269e3021894	3622	etharp_query() now always DOES call ETHARP_TRY_HARD so that users
elessair	0:f269e3021894	3623	querying an address will see it appear in the cache (DHCP could
elessair	0:f269e3021894	3624	suffer from this when a server invalidly gave an in-use address.)
elessair	0:f269e3021894	3625	* ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
elessair	0:f269e3021894	3626	comparing network addresses (identifiers), not the network masks
elessair	0:f269e3021894	3627	themselves.
elessair	0:f269e3021894	3628	* ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
elessair	0:f269e3021894	3629	IP address actually belongs to the network of the given interface.

elessair	0:f269e3021894	3637	* tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
elessair	0:f269e3021894	3638	even if one is already pending, if the rcv_wnd is above a threshold
elessair	0:f269e3021894	3639	(currently TCP_WND/2). This avoids waiting for a timer to expire to send a
elessair	0:f269e3021894	3640	delayed ACK in order to open the window if the stack is only receiving data.

elessair	0:f269e3021894	3657	* inet.c: Added a couple of casts to quiet the compiler.
elessair	0:f269e3021894	3658	No need to test isascii(c) before isdigit(c) or isxdigit(c).

elessair	0:f269e3021894	3669	netif->linkoutput and changed low_level_input() similarly for consistency.
elessair	0:f269e3021894	3670	* api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
elessair	0:f269e3021894	3671	of raw_recv() in raw.h and so avoid compiler error.
elessair	0:f269e3021894	3672	* sockets.c: Added trivial (int) cast to keep compiler happier.
elessair	0:f269e3021894	3673	* ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.

elessair	0:f269e3021894	3681	your cc.h file defines this either 1 or 0. If non-defined,

elessair	0:f269e3021894	3811	if an outgoing packet can be directly sent on the link, or perform
elessair	0:f269e3021894	3812	a copy-on-demand when necessary.
elessair	0:f269e3021894	3813
elessair	0:f269e3021894	3814	The application can safely assume the packet is sent, and the RAM
elessair	0:f269e3021894	3815	is available to the application directly after calling udp_send()
elessair	0:f269e3021894	3816	or similar function.

elessair	0:f269e3021894	3828
elessair	0:f269e3021894	3829	* The packet buffer implementation is changed. The pbuf->ref counter
elessair	0:f269e3021894	3830	meaning has changed, and several pbuf functions have been
elessair	0:f269e3021894	3831	adapted accordingly.
elessair	0:f269e3021894	3832
elessair	0:f269e3021894	3833	* netif drivers have to be changed to set the hardware address length field
elessair	0:f269e3021894	3834	that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).
elessair	0:f269e3021894	3835	See the contrib/ports/c16x cs8900 driver as a driver example.
elessair	0:f269e3021894	3836

elessair	0:f269e3021894	4010	* General: A lot of code cleaned up and debugging code removed. Many
elessair	0:f269e3021894	4011	portability issues have been fixed.
elessair	0:f269e3021894	4012
elessair	0:f269e3021894	4013	* The license was changed; the advertising clause was removed.
elessair	0:f269e3021894	4014
elessair	0:f269e3021894	4015	* C64 port added.
elessair	0:f269e3021894	4016
elessair	0:f269e3021894	4017	* Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri
elessair	0:f269e3021894	4018	Kosunen, Mikael Caleres, and Frits Wilmink for reporting and
elessair	0:f269e3021894	4019	fixing bugs!
elessair	0:f269e3021894	4020
elessair	0:f269e3021894	4021	(0.4) Changes since version 0.3.1
elessair	0:f269e3021894	4022
elessair	0:f269e3021894	4023	* Memory management has been radically changed; instead of
elessair	0:f269e3021894	4024	allocating memory from a shared heap, memory for objects that are
elessair	0:f269e3021894	4025	rapidly allocated and deallocated is now kept in pools. Allocation
elessair	0:f269e3021894	4026	and deallocation from those memory pools is very fast. The shared
elessair	0:f269e3021894	4027	heap is still present but is used less frequently.
elessair	0:f269e3021894	4028
elessair	0:f269e3021894	4029	* The memory, memory pool, and packet buffer subsystems now support
elessair	0:f269e3021894	4030	4-, 2-, or 1-byte alignment.
elessair	0:f269e3021894	4031
elessair	0:f269e3021894	4032	* "Out of memory" situations are handled in a more robust way.
elessair	0:f269e3021894	4033
elessair	0:f269e3021894	4034	* Stack usage has been reduced.
elessair	0:f269e3021894	4035
elessair	0:f269e3021894	4036	* Easier configuration of lwIP parameters such as memory usage,
elessair	0:f269e3021894	4037	TTLs, statistics gathering, etc. All configuration parameters are
elessair	0:f269e3021894	4038	now kept in a single header file "lwipopts.h".
elessair	0:f269e3021894	4039
elessair	0:f269e3021894	4040	* The directory structure has been changed slightly so that all
elessair	0:f269e3021894	4041	architecture specific files are kept under the src/arch
elessair	0:f269e3021894	4042	hierarchy.
elessair	0:f269e3021894	4043
elessair	0:f269e3021894	4044	* Error propagation has been improved, both in the protocol modules
elessair	0:f269e3021894	4045	and in the API.
elessair	0:f269e3021894	4046
elessair	0:f269e3021894	4047	* The code for the RTXC architecture has been implemented, tested
elessair	0:f269e3021894	4048	and put to use.
elessair	0:f269e3021894	4049
elessair	0:f269e3021894	4050	* Bugs have been found and corrected in the TCP, UDP, IP, API, and
elessair	0:f269e3021894	4051	the Internet checksum modules.
elessair	0:f269e3021894	4052
elessair	0:f269e3021894	4053	* Bugs related to porting between a 32-bit and a 16-bit architecture
elessair	0:f269e3021894	4054	have been found and corrected.
elessair	0:f269e3021894	4055
elessair	0:f269e3021894	4056	* The license has been changed slightly to conform more with the
elessair	0:f269e3021894	4057	original BSD license, including the advertisement clause.
elessair	0:f269e3021894	4058
elessair	0:f269e3021894	4059	(0.3.1) Changes since version 0.3
elessair	0:f269e3021894	4060
elessair	0:f269e3021894	4061	* Fix of a fatal bug in the buffer management. Pbufs with allocated
elessair	0:f269e3021894	4062	RAM never returned the RAM when the pbuf was deallocated.
elessair	0:f269e3021894	4063
elessair	0:f269e3021894	4064	* TCP congestion control, window updates and retransmissions did not
elessair	0:f269e3021894	4065	work correctly. This has now been fixed.
elessair	0:f269e3021894	4066
elessair	0:f269e3021894	4067	* Bugfixes in the API.
elessair	0:f269e3021894	4068
elessair	0:f269e3021894	4069	(0.3) Changes since version 0.2
elessair	0:f269e3021894	4070
elessair	0:f269e3021894	4071	* New and improved directory structure. All include files are now
elessair	0:f269e3021894	4072	kept in a dedicated include/ directory.
elessair	0:f269e3021894	4073
elessair	0:f269e3021894	4074	* The API now has proper error handling. A new function,
elessair	0:f269e3021894	4075	netconn_err(), now returns an error code for the connection in
elessair	0:f269e3021894	4076	case of errors.
elessair	0:f269e3021894	4077
elessair	0:f269e3021894	4078	* Improvements in the memory management subsystem. The system now
elessair	0:f269e3021894	4079	keeps a pointer to the lowest free memory block. A new function,
elessair	0:f269e3021894	4080	mem_malloc2() tries to allocate memory once, and if it fails tries
elessair	0:f269e3021894	4081	to free some memory and retry the allocation.
elessair	0:f269e3021894	4082
elessair	0:f269e3021894	4083	* Much testing has been done with limited memory
elessair	0:f269e3021894	4084	configurations. lwIP now does a better job when overloaded.
elessair	0:f269e3021894	4085
elessair	0:f269e3021894	4086	* Some bugfixes and improvements to the buffer (pbuf) subsystem.
elessair	0:f269e3021894	4087
elessair	0:f269e3021894	4088	* Many bugfixes in the TCP code:
elessair	0:f269e3021894	4089
elessair	0:f269e3021894	4090	- Fixed a bug in tcp_close().
elessair	0:f269e3021894	4091
elessair	0:f269e3021894	4092	- The TCP receive window was incorrectly closed when out of
elessair	0:f269e3021894	4093	sequence segments was received. This has been fixed.
elessair	0:f269e3021894	4094
elessair	0:f269e3021894	4095	- Connections are now timed-out of the FIN-WAIT-2 state.
elessair	0:f269e3021894	4096
elessair	0:f269e3021894	4097	- The initial congestion window could in some cases be too
elessair	0:f269e3021894	4098	large. This has been fixed.
elessair	0:f269e3021894	4099
elessair	0:f269e3021894	4100	- The retransmission queue could in some cases be screwed up. This
elessair	0:f269e3021894	4101	has been fixed.
elessair	0:f269e3021894	4102
elessair	0:f269e3021894	4103	- TCP RST flag now handled correctly.
elessair	0:f269e3021894	4104
elessair	0:f269e3021894	4105	- Out of sequence data was in some cases never delivered to the
elessair	0:f269e3021894	4106	application. This has been fixed.
elessair	0:f269e3021894	4107
elessair	0:f269e3021894	4108	- Retransmitted segments now contain the correct acknowledgment
elessair	0:f269e3021894	4109	number and advertised window.
elessair	0:f269e3021894	4110
elessair	0:f269e3021894	4111	- TCP retransmission timeout backoffs are not correctly computed
elessair	0:f269e3021894	4112	(ala BSD). After a number of retransmissions, TCP now gives up
elessair	0:f269e3021894	4113	the connection.
elessair	0:f269e3021894	4114
elessair	0:f269e3021894	4115	* TCP connections now are kept on three lists, one for active
elessair	0:f269e3021894	4116	connections, one for listening connections, and one for
elessair	0:f269e3021894	4117	connections that are in TIME-WAIT. This greatly speeds up the fast
elessair	0:f269e3021894	4118	timeout processing for sending delayed ACKs.
elessair	0:f269e3021894	4119
elessair	0:f269e3021894	4120	* TCP now provides proper feedback to the application when a
elessair	0:f269e3021894	4121	connection has been successfully set up.
elessair	0:f269e3021894	4122
elessair	0:f269e3021894	4123	* More comments have been added to the code. The code has also been
elessair	0:f269e3021894	4124	somewhat cleaned up.
elessair	0:f269e3021894	4125
elessair	0:f269e3021894	4126	(0.2) Initial public release.
