3 * TODO: The lwIP source code makes some invalid assumptions on processor
\r
4 word-length, storage sizes and alignment. See the mailing lists for
\r
5 problems with exoteric (/DSP) architectures showing these problems.
\r
6 We still have to fix some of these issues neatly.
\r
8 * TODO: the PPP code is broken in a few ways. There are namespace
\r
9 collisions on BSD systems and many assumptions on word-length
\r
10 (sizeof(int)). In ppp.c an assumption is made on the availability of
\r
11 a thread subsystem. Either PPP needs to be moved to contrib/ports/???
\r
12 or rearranged to be more generic.
\r

\r
30 2008-03-10 Jonathan Larmour
\r
31 * inet_chksum.c: Allow choice of one of the sample algorithms to be
\r
32 made from lwipopts.h. Fix comment on how to override LWIP_CHKSUM.
\r
34 2008-01-22 Frédéric Bernon
\r
35 * tcp.c, tcp_in.c, tcp.h, opt.h: Rename LWIP_CALCULATE_EFF_SEND_MSS in
\r
36 TCP_CALCULATE_EFF_SEND_MSS to have coherent TCP options names.
\r
38 2008-01-14 Frédéric Bernon
\r
39 * rawapi.txt, api_msg.c, tcp.c, tcp_in.c, tcp.h: changes for task #7675 "Enable
\r
40 to refuse data on a TCP_EVENT_RECV call". Important, behavior changes for the
\r
41 tcp_recv callback (see rawapi.txt).
\r
43 2008-01-14 Frédéric Bernon, Marc Chaland
\r
44 * ip.c: Integrate patch #6369" ip_input : checking before realloc".
\r
46 2008-01-12 Frédéric Bernon
\r
47 * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
\r
48 netconn::sem per netconn::op_completed like suggested for the task #7490
\r
49 "Add return value to sys_mbox_post".
\r
51 2008-01-12 Frédéric Bernon
\r
52 * api_msg.c, opt.h: replace DEFAULT_RECVMBOX_SIZE per DEFAULT_TCP_RECVMBOX_SIZE,
\r
53 DEFAULT_UDP_RECVMBOX_SIZE and DEFAULT_RAW_RECVMBOX_SIZE (to optimize queues
\r
54 sizes), like suggested for the task #7490 "Add return value to sys_mbox_post".
\r
56 2008-01-10 Frédéric Bernon
\r
57 * tcpip.h, tcpip.c: add tcpip_callback_with_block function for the task #7490
\r
58 "Add return value to sys_mbox_post". tcpip_callback is always defined as
\r
59 "blocking" ("block" parameter = 1).
\r
61 2008-01-10 Frédéric Bernon
\r
62 * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
\r
63 netconn::mbox (sys_mbox_t) per netconn::sem (sys_sem_t) for the task #7490
\r
64 "Add return value to sys_mbox_post".
\r
66 2008-01-05 Frédéric Bernon
\r
67 * sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h, opt.h:
\r
68 Introduce changes for task #7490 "Add return value to sys_mbox_post" with some
\r
69 modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which
\r
70 indicate the number of pointers query by the mailbox. There is three defines
\r
71 in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the
\r
72 netconn::acceptmbox. Port maintainers, you can decide to just add this new
\r
73 parameter in your implementation, but to ignore it to keep the previous behavior.
\r
74 The new sys_mbox_trypost function return a value to know if the mailbox is
\r
75 full or if the message is posted. Take a look to sys_arch.txt for more details.
\r
76 This new function is used in tcpip_input (so, can be called in an interrupt
\r
77 context since the function is not blocking), and in recv_udp and recv_raw.
\r
79 2008-01-04 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
\r
80 * rawapi.txt, api.h, api_lib.c, api_msg.h, api_msg.c, sockets.c, tcp.h, tcp.c,
\r
81 tcp_in.c, init.c, opt.h: rename backlog options with TCP_ prefix, limit the
\r
82 "backlog" parameter in an u8_t, 0 is interpreted as "smallest queue", add
\r
83 documentation in the rawapi.txt file.
\r
85 2007-12-31 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
\r
86 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Add TCP persist timer
\r
88 2007-12-31 Frédéric Bernon, Luca Ceresoli
\r
89 * autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP packets
\r
90 in autoip". The change in etharp_raw could be removed, since all calls to
\r
91 etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be
\r
92 wrong in the future.
\r
94 2007-12-30 Frédéric Bernon, Tom Evans
\r
95 * ip.c: Fix bug #21846 "LwIP doesn't appear to perform any IP Source Address
\r
96 Filtering" reported by Tom Evans.
\r
98 2007-12-21 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
\r
99 * tcp.h, opt.h, api.h, api_msg.h, tcp.c, tcp_in.c, api_lib.c, api_msg.c,
\r
100 sockets.c, init.c: task #7252: Implement TCP listen backlog: Warning: raw API
\r
101 applications have to call 'tcp_accepted(pcb)' in their accept callback to
\r
102 keep accepting new connections.
\r
104 2007-12-13 Frédéric Bernon
\r
105 * api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum dns_result"
\r
106 by err_t type. Add a new err_t code "ERR_INPROGRESS".
\r
108 2007-12-12 Frédéric Bernon
\r
109 * dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles
\r
110 are the one which have ram usage.
\r
112 2007-12-05 Frédéric Bernon
\r
113 * netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static
\r
114 set of variables (=0) or a local one (=1). In this last case, your port should
\r
115 provide a function "struct hostent* sys_thread_hostent( struct hostent* h)"
\r
116 which have to do a copy of "h" and return a pointer ont the "per-thread" copy.
\r
118 2007-12-03 Simon Goldschmidt
\r
119 * ip.c: ip_input: check if a packet is for inp first before checking all other
\r
120 netifs on netif_list (speeds up packet receiving in most cases)
\r
122 2007-11-30 Simon Goldschmidt
\r
123 * udp.c, raw.c: task #7497: Sort lists (pcb, netif, ...) for faster access
\r
124 UDP: move a (connected) pcb selected for input to the front of the list of
\r
125 pcbs so that it is found faster next time. Same for RAW pcbs that have eaten
\r
128 2007-11-28 Simon Goldschmidt
\r
129 * etharp.c, stats.c, stats.h, opt.h: Introduced ETHARP_STATS
\r
131 2007-11-25 Simon Goldschmidt
\r
132 * dhcp.c: dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy
\r
135 2007-11-24 Simon Goldschmidt
\r
136 * netdb.h, netdb.c, sockets.h/.c: Moved lwip_gethostbyname from sockets.c
\r
137 to the new file netdb.c; included lwip_getaddrinfo.
\r
139 2007-11-21 Simon Goldschmidt
\r
140 * tcp.h, opt.h, tcp.c, tcp_in.c: implemented calculating the effective send-mss
\r
141 based on the MTU of the netif used to send. Enabled by default. Disable by
\r
142 setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21492.
\r
144 2007-11-19 Frédéric Bernon
\r
145 * api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name
\r
146 received match the name query), implement DNS_USES_STATIC_BUF (the place where
\r
147 copy dns payload to parse the response), return an error if there is no place
\r
148 for a new query, and fix some minor problems.
\r
150 2007-11-16 Simon Goldschmidt
\r
151 * new files: ipv4/inet.c, ipv4/inet_chksum.c, ipv6/inet6.c
\r
152 removed files: core/inet.c, core/inet6.c
\r
153 Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into
\r
154 inet and chksum part; changed includes in all lwIP files as appropriate
\r
156 2007-11-16 Simon Goldschmidt
\r
157 * api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential
\r
158 dns resolver function for netconn api (netconn_gethostbyname) and socket api
\r
159 (gethostbyname/gethostbyname_r).
\r
161 2007-11-15 Jim Pettinato, Frédéric Bernon
\r
162 * opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name
\r
163 requests with RAW api interface. Initialization is done in lwip_init() with
\r
164 build time options. DNS timer is added in tcpip_thread context. DHCP can set
\r
165 DNS server ip addresses when options are received. You need to set LWIP_DNS=1
\r
166 in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get
\r
167 some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo"
\r
168 list with points to improve.
\r
170 2007-11-06 Simon Goldschmidt
\r
171 * opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly
\r
172 enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status
\r
173 for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.
\r
175 2007-11-06 Simon Goldschmidt
\r
176 * api.h, api_msg.h and dependent files: Task #7410: Removed the need to include
\r
177 core header files in api.h (ip/tcp/udp/raw.h) to hide the internal
\r
178 implementation from netconn api applications.
\r
180 2007-11-03 Frédéric Bernon
\r
181 * api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP &
\r
182 RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled
\r
183 by default). Netconn API users can use the netconn_recv_bufsize macro to access
\r
184 it. This is a first release which have to be improve for TCP. Note it used the
\r
185 netconn::recv_avail which need to be more "thread-safe" (note there is already
\r
186 the problem for FIONREAD with lwip_ioctl/ioctlsocket).
\r
188 2007-11-01 Frédéric Bernon, Marc Chaland
\r
189 * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c:
\r
190 Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api
\r
191 layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api
\r
192 layer. This option enable to delayed TCP PUSH flag on multiple "write" calls.
\r
193 Note that previous "copy" parameter for "write" APIs is now called "apiflags".
\r
195 2007-10-24 Frédéric Bernon
\r
196 * api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than
\r
197 TCP_EVENT_xxx macros to get a code more readable. It could also help to remove
\r
198 some code (like we have talk in "patch #5919 : Create compile switch to remove
\r
199 select code"), but it could be done later.
\r
201 2007-10-08 Simon Goldschmidt
\r
202 * many files: Changed initialization: many init functions are not needed any
\r
203 more since we now rely on the compiler initializing global and static
\r
206 2007-10-06 Simon Goldschmidt
\r
207 * ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY
\r
208 to enqueue the received pbufs so that multiple packets can be reassembled
\r
209 simultaneously and no static reassembly buffer is needed.
\r
211 2007-10-05 Simon Goldschmidt
\r
212 * tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so
\r
213 all netifs (or ports) can use it.
\r
215 2007-10-05 Frédéric Bernon
\r
216 * netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the
\r
217 common function to reduce a little bit the footprint (for all functions using
\r
218 only the "netif" parameter).
\r
220 2007-10-03 Frédéric Bernon
\r
221 * netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down,
\r
222 netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce
\r
223 a little bit the footprint (for all functions using only the "netif" parameter).
\r
225 2007-09-15 Frédéric Bernon
\r
226 * udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF
\r
227 option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for
\r
228 netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for
\r
229 IP_MULTICAST_TTL and IP_MULTICAST_IF.
\r
231 2007-09-10 Frédéric Bernon
\r
232 * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles
\r
233 even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime()
\r
234 each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can
\r
235 decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but
\r
236 call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime()
\r
237 or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
\r
238 This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
\r
239 snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
\r
240 when it's queried (any direct call to "sysuptime" is changed by a call to
\r
241 snmp_get_sysuptime).
\r
243 2007-09-09 Frédéric Bernon, Bill Florac
\r
244 * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP,
\r
245 and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags
\r
246 if you want IGMP on an interface. igmp_stop() is now called inside netif_remove().
\r
247 igmp_report_groups() is now called inside netif_set_link_up() (need to have
\r
248 LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait
\r
249 the next query message to receive the matching multicast streams).
\r
251 2007-09-08 Frédéric Bernon
\r
252 * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains
\r
253 IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change).
\r
254 Use this new field to access to common pcb fields (ttl, tos, so_options, etc...).
\r
255 Enable to access to these fields with LWIP_TCP=0.
\r
257 2007-09-05 Frédéric Bernon
\r
258 * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h,
\r
259 ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option
\r
260 LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default).
\r
261 Be careful, disabling ICMP make your product non-compliant to RFC1122, but
\r
262 help to reduce footprint, and to reduce "visibility" on the Internet.
\r
264 2007-09-05 Frédéric Bernon, Bill Florac
\r
265 * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list
\r
266 for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new
\r
267 parameters have to be provided: a task name, and a task stack size. For this
\r
268 one, since it's platform dependant, you could define the best one for you in
\r
269 your lwipopts.h. For port maintainers, you can just add these new parameters
\r
270 in your sys_arch.c file, and but it's not mandatory, use them in your OS
\r
271 specific functions.
\r
273 2007-09-05 Frédéric Bernon
\r
274 * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings
\r
275 inside init.c for task #7142 "Sanity check user-configurable values".
\r
277 2007-09-04 Frédéric Bernon, Bill Florac
\r
278 * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by
\r
279 memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the
\r
280 value). It will avoid potential fragmentation problems, use a counter to know
\r
281 how many times a group is used on an netif, and free it when all applications
\r
282 leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity
\r
283 check if LWIP_IGMP!=0).
\r
285 2007-09-03 Frédéric Bernon
\r
286 * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement".
\r
287 Initialize igmp_mac_filter to NULL in netif_add (this field should be set in
\r
288 the netif's "init" function). Use the "imr_interface" field (for socket layer)
\r
289 and/or the "interface" field (for netconn layer), for join/leave operations.
\r
290 The igmp_join/leavegroup first parameter change from a netif to an ipaddr.
\r
291 This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany).
\r
293 2007-08-30 Frédéric Bernon
\r
294 * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions
\r
295 from api/api_lib". Now netbuf API is independant of netconn, and can be used
\r
296 with other API (application based on raw API, or future "socket2" API). Ports
\r
297 maintainers just have to add src/api/netbuf.c in their makefile/projects.
\r
299 2007-08-30 Frédéric Bernon, Jonathan Larmour
\r
300 * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check
\r
301 user-configurable values".
\r
303 2007-08-29 Frédéric Bernon
\r
304 * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start.
\r
305 igmp_start is call inside netif_add. Now, igmp initialization is in the same
\r
306 spirit than the others modules. Modify some IGMP debug traces.
\r
308 2007-08-29 Frédéric Bernon
\r
309 * Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function"
\r
310 Add lwip_init function to regroup all modules initializations, and to provide
\r
311 a place to add code for task #7142 "Sanity check user-configurable values".
\r
312 Ports maintainers should remove direct initializations calls from their code,
\r
313 and add init.c in their makefiles. Note that lwip_init() function is called
\r
314 inside tcpip_init, but can also be used by raw api users since all calls are
\r
315 disabled when matching options are disabled. Also note that their is new options
\r
316 in opt.h, you should configure in your lwipopts.h (they are enabled per default).
\r
318 2007-08-26 Marc Boucher
\r
319 * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL
\r
320 since they can under certain circumstances be called with an invalid conn
\r
321 pointer after the connection has been closed (and conn has been freed).
\r
323 2007-08-25 Frédéric Bernon (Artem Migaev's Patch)
\r
324 * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up".
\r
325 Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set.
\r
327 2007-08-22 Frédéric Bernon
\r
328 * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK
\r
329 to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release.
\r
331 2007-08-22 Frédéric Bernon
\r
332 * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT &
\r
333 ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the
\r
334 name is tcpip_input (we keep the name of 1.2.0 function).
\r
336 2007-08-17 Jared Grubb
\r
337 * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool
\r
338 settings into new memp_std.h and optional user file lwippools.h. This adds
\r
339 more dynamic mempools, and allows the user to create an arbitrary number of
\r
340 mempools for mem_malloc.
\r
342 2007-08-16 Marc Boucher
\r
343 * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function;
\r
344 otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely
\r
345 close the connection.
\r
347 2007-08-16 Marc Boucher
\r
348 * sockets.c: lwip_accept(): check netconn_peer() error return.
\r
350 2007-08-16 Marc Boucher
\r
351 * mem.c, mem.h: Added mem_calloc().
\r
353 2007-08-16 Marc Boucher
\r
354 * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT)
\r
355 for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG
\r
356 and starving other message types.
\r
357 Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API
\r
359 2007-08-16 Marc Boucher
\r
360 * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf
\r
361 type and flgs (later renamed to flags).
\r
362 Use enum pbuf_flag as pbuf_type. Renumber PBUF_FLAG_*.
\r
363 Improved lwip_recvfrom(). TCP push now propagated.
\r
365 2007-08-16 Marc Boucher
\r
366 * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global
\r
367 provided by etharp.
\r
369 2007-08-16 Marc Boucher
\r
370 * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h,
\r
371 etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c:
\r
372 Added PPPoE support and various PPP improvements.
\r
374 2007-07-25 Simon Goldschmidt
\r
375 * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial,
\r
376 making netbuf_copy_partial use this function.
\r
378 2007-07-25 Simon Goldschmidt
\r
379 * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with
\r
380 2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and
\r
383 2007-07-13 Jared Grubb (integrated by Frédéric Bernon)
\r
384 * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add
\r
385 a link callback in the netif struct, and functions to handle it. Be carefull
\r
386 for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c)
\r
387 if you want to be sure to be compatible with future changes...
\r
389 2007-06-30 Frédéric Bernon
\r
390 * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.
\r
392 2007-06-21 Simon Goldschmidt
\r
393 * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both
\r
394 LWIP_AUTOIP =0 and =1 to remove redundant code.
\r
396 2007-06-21 Simon Goldschmidt
\r
397 * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option
\r
398 MEM_USE_POOLS to use 4 pools with different sized elements instead of a
\r
399 heap. This both prevents memory fragmentation and gives a higher speed
\r
400 at the cost of more memory consumption. Turned off by default.
\r
402 2007-06-21 Simon Goldschmidt
\r
403 * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of
\r
404 netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into
\r
405 int to be able to send a bigger buffer than 64K with one time (mainly
\r
406 used from lwip_send).
\r
408 2007-06-21 Simon Goldschmidt
\r
409 * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write
\r
410 into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too.
\r
412 2007-06-21 Simon Goldschmidt
\r
413 * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in
\r
414 netconn_write from api_lib.c to api_msg.c to also prevent multiple context-
\r
415 changes on low memory or empty send-buffer.
\r
417 2007-06-18 Simon Goldschmidt
\r
418 * etharp.c, etharp.h: Changed etharp to use a defined hardware address length
\r
419 of 6 to avoid loading netif->hwaddr_len every time (since this file is only
\r
420 used for ethernet and struct eth_addr already had a defined length of 6).
\r
422 2007-06-17 Simon Goldschmidt
\r
423 * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets
\r
424 to disable UDP checksum generation on transmit.
\r
426 2007-06-13 Frédéric Bernon, Simon Goldschmidt
\r
427 * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid
\r
428 pointers or parameters, and let the possibility to redefined it in cc.h. Use
\r
429 this macro to check "conn" parameter in api_msg.c functions.
\r
431 2007-06-11 Simon Goldschmidt
\r
432 * sockets.c, sockets.h: Added UDP lite support for sockets
\r
434 2007-06-10 Simon Goldschmidt
\r
435 * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled
\r
436 by default) to switch off UDP-Lite support if not needed (reduces udp.c code
\r
439 2007-06-09 Dominik Spies (integrated by Frédéric Bernon)
\r
440 * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h:
\r
441 AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and
\r
442 LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt
\r
443 (see TODO mark in the source code).
\r
445 2007-06-09 Simon Goldschmidt
\r
446 * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for
\r
447 etharp_output() to match netif->output so etharp_output() can be used
\r
448 directly as netif->output to save one function call.
\r
450 2007-06-08 Simon Goldschmidt
\r
451 * netif.h, ethernetif.c, slipif.c, loopif.c: Added define
\r
452 NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables,
\r
453 added initialization of those to ethernetif, slipif and loopif.
\r
455 2007-05-18 Simon Goldschmidt
\r
456 * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF
\r
457 (defaulting to off for now) that can be set to 0 to send fragmented
\r
458 packets by passing PBUF_REFs down the stack.
\r
460 2007-05-23 Frédéric Bernon
\r
461 * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP
\r
462 connections, such present in patch #5959.
\r
464 2007-05-23 Frédéric Bernon
\r
465 * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx
\r
466 code in only one part...
\r
468 2007-05-18 Simon Goldschmidt
\r
469 * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp
\r
470 elements to overflow. This is achieved by adding some bytes before and after
\r
471 each pool element (increasing their size, of course), filling them with a
\r
472 prominent value and checking them on freeing the element.
\r
473 Set it to 2 to also check every element in every pool each time memp_malloc()
\r
474 or memp_free() is called (slower but more helpful).
\r
476 2007-05-10 Simon Goldschmidt
\r
477 * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for
\r
478 PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce
\r
481 2007-05-11 Frédéric Bernon
\r
482 * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c:
\r
483 Include a function pointer instead of a table index in the message to reduce
\r
484 footprint. Disable some part of lwip_send and lwip_sendto if some options are
\r
485 not set (LWIP_TCP, LWIP_UDP, LWIP_RAW).
\r
487 2007-05-10 Simon Goldschmidt
\r
488 * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus
\r
489 \ extern "C" {' in all header files. Now you can write your application using
\r
490 the lwIP stack in C++ and simply #include the core files. Note I have left
\r
491 out the netif/ppp/*h header files for now, since I don't know which files are
\r
492 included by applications and which are for internal use only.
\r
494 2007-05-09 Simon Goldschmidt
\r
495 * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library
\r
496 memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for
\r
497 situations where some compilers might inline the copy and save a function
\r
498 call. Also replaced all calls to memcpy() with calls to (S)MEMCPY().
\r
500 2007-05-08 Simon Goldschmidt
\r
501 * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc())
\r
502 to be overriden in case the C-library malloc implementation is not protected
\r
503 against concurrent access.
\r
505 2007-05-04 Simon Goldschmidt (Atte Kojo)
\r
506 * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending
\r
507 multiple packets to the same host.
\r
509 2007-05-04 Frédéric Bernon, Jonathan Larmour
\r
510 * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible
\r
511 to corrupt remote addr/port connection state". Reduce problems "not enought memory" with
\r
512 netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between
\r
513 sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function.
\r
514 Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct,
\r
515 these fields are now renamed "addr" & "port".
\r
517 2007-04-11 Jonathan Larmour
\r
518 * sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new
\r
519 sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return
\r
520 with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro
\r
521 by the port in sys_arch.h if desired.
\r
523 2007-04-06 Frédéric Bernon, Simon Goldschmidt
\r
524 * opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API
\r
525 allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp
\r
526 clients, using new functions from netifapi.h. Disable as default (no port change to do).
\r
528 2007-04-05 Frédéric Bernon
\r
529 * sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant.
\r
531 2007-04-04 Simon Goldschmidt
\r
532 * arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x)
\r
533 use this for and architecture-independent form to tell the compiler you intentionally
\r
534 are not using this variable. Can be overriden in cc.h.
\r
536 2007-03-28 Frédéric Bernon
\r
537 * opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to
\r
538 define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded
\r
539 string, point on one of your's ethernetif field, or alloc a string you will free yourself).
\r
540 It will be used by DHCP to register a client hostname, but can also be use when you call
\r
543 2007-03-28 Frédéric Bernon
\r
544 * netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to
\r
545 initialize a network interface's flag with. It tell this interface is an ethernet
\r
546 device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility
\r
547 Support for IPv4" section 4.6) when interface is "up" with netif_set_up().
\r
549 2007-03-26 Frédéric Bernon, Jonathan Larmour
\r
550 * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build
\r
551 time if you only use PPP or SLIP. The default is enable. Note we don't have to call
\r
552 etharp_init in your port's initilization sequence if you use tcpip.c, because this call
\r
553 is done in tcpip_init function.
\r
555 2007-03-22 Frédéric Bernon
\r
556 * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the
\r
557 new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in
\r
558 your lwipopts.h. More, unused counters are not defined in the stats structs, and not
\r
559 display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined
\r
560 but never used. Fix msg_in.c with the correct #if test for a stat display.
\r
562 2007-03-21 Kieran Mansley
\r
563 * netif.c, netif.h: Apply patch#4197 with some changes (originator: rireland@hmgsl.com).
\r
564 Provides callback on netif up/down state change.
\r
566 2007-03-11 Frédéric Bernon, Mace Gael, Steve Reynolds
\r
567 * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, igmp.h, igmp.c,
\r
568 ip.c, netif.h, tcpip.c, opt.h:
\r
569 New configuration option LWIP_IGMP to enable IGMP processing. Based on only one
\r
570 filter per all network interfaces. Declare a new function in netif to enable to
\r
571 control the MAC filter (to reduce lwIP traffic processing).
\r
573 2007-03-11 Frédéric Bernon
\r
574 * tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can
\r
575 be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this
\r
576 unless you know what you're doing (default are RFC1122 compliant). Note
\r
577 that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds.
\r
579 2007-03-08 Frédéric Bernon
\r
580 * tcp.h: Keepalive values can be configured at compile time, but don't change
\r
581 this unless you know what you're doing (default are RFC1122 compliant).
\r
583 2007-03-08 Frédéric Bernon
\r
584 * sockets.c, api.h, api_lib.c, tcpip.c, sys.h, sys.c, err.c, opt.h:
\r
585 Implement LWIP_SO_RCVTIMEO configuration option to enable/disable SO_RCVTIMEO
\r
586 on UDP sockets/netconn.
\r
588 2007-03-08 Simon Goldschmidt
\r
589 * snmp_msg.h, msg_in.c: SNMP UDP ports can be configured at compile time.
\r
591 2007-03-06 Frédéric Bernon
\r
592 * api.h, api_lib.c, sockets.h, sockets.c, tcpip.c, sys.h, sys.c, err.h:
\r
593 Implement SO_RCVTIMEO on UDP sockets/netconn.
\r
595 2007-02-28 Kieran Mansley (based on patch from Simon Goldschmidt)
\r
596 * api_lib.c, tcpip.c, memp.c, memp.h: make API msg structs allocated
\r
597 on the stack and remove the API msg type from memp
\r
599 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
\r
600 * sockets.h, sockets.c: Move socket initialization to new
\r
601 lwip_socket_init() function.
\r
602 NOTE: this changes the API with ports. Ports will have to be
\r
603 updated to call lwip_socket_init() now.
\r
605 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
\r
606 * api_lib.c: Use memcpy in netbuf_copy_partial.
\r
611 2008-03-17 Frédéric Bernon, Ed Kerekes
\r
612 * igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have
\r
613 some problems to fill the IP header on some targets, use now the
\r
614 ip.h macros to do it).
\r
616 2008-03-13 Frédéric Bernon
\r
617 * sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using
\r
618 (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a
\r
619 TCP connection caused a crash. Note that using (lwip_)recvfrom
\r
620 like this is a bit slow and that using (lwip)getpeername is the
\r
621 good lwip way to do it (so, using recv is faster on tcp sockets).
\r
623 2008-03-12 Frédéric Bernon, Jonathan Larmour
\r
624 * api_msg.c, contrib/apps/ping.c: Fix bug #22530 "api_msg.c's
\r
625 recv_raw() does not consume data", and the ping sample (with
\r
626 LWIP_SOCKET=1, the code did the wrong supposition that lwip_recvfrom
\r
627 returned the IP payload, without the IP header).
\r
629 2008-03-04 Jonathan Larmour
\r
630 * mem.c, stats.c, mem.h: apply patch #6414 to avoid compiler errors
\r
631 and/or warnings on some systems where mem_size_t and size_t differ.
\r
632 * pbuf.c, ppp.c: Fix warnings on some systems with mem_malloc.
\r
634 2008-03-04 Kieran Mansley (contributions by others)
\r
635 * Numerous small compiler error/warning fixes from contributions to
\r
636 mailing list after 1.3.0 release candidate made.
\r
638 2008-01-25 Cui hengbin (integrated by Frédéric Bernon)
\r
639 * dns.c: Fix bug #22108 "DNS problem" caused by unaligned structures.
\r
641 2008-01-15 Kieran Mansley
\r
642 * tcp_out.c: BUG20511. Modify persist timer to start when we are
\r
643 prevented from sending by a small send window, not just a zero
\r
646 2008-01-09 Jonathan Larmour
\r
647 * opt.h, ip.c: Rename IP_OPTIONS define to IP_OPTIONS_ALLOWED to avoid
\r
648 conflict with Linux system headers.
\r
650 2008-01-06 Jonathan Larmour
\r
651 * dhcp.c: fix bug #19927: "DHCP NACK problem" by clearing any existing set IP
\r
652 address entirely on receiving a DHCPNAK, and restarting discovery.
\r
654 2007-12-21 Simon Goldschmidt
\r
655 * sys.h, api_lib.c, api_msg.c, sockets.c: fix bug #21698: "netconn->recv_avail
\r
656 is not protected" by using new macros for interlocked access to modify/test
\r
657 netconn->recv_avail.
\r
659 2007-12-20 Kieran Mansley (based on patch from Oleg Tyshev)
\r
660 * tcp_in.c: fix bug# 21535 (nrtx not reset correctly in SYN_SENT state)
\r
662 2007-12-20 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
\r
663 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: fix bug #20199 (better handling
\r
664 of silly window avoidance and prevent lwIP from shrinking the window)
\r
666 2007-12-04 Simon Goldschmidt
\r
667 * tcp.c, tcp_in.c: fix bug #21699 (segment leak in ooseq processing when last
\r
668 data packet was lost): add assert that all segment lists are empty in
\r
669 tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED
\r
670 state from LAST_ACK in tcp_process
\r
672 2007-12-02 Simon Goldschmidt
\r
673 * sockets.h: fix bug #21654: exclude definition of struct timeval from #ifndef FD_SET
\r
674 If including <sys/time.h> for system-struct timeval, LWIP_TIMEVAL_PRIVATE now
\r
675 has to be set to 0 in lwipopts.h
\r
677 2007-12-02 Simon Goldschmidt
\r
678 * api_msg.c, api_lib.c: fix bug #21656 (recvmbox problem in netconn API): always
\r
679 allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen
\r
680 netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox.
\r
681 This is a fix for thread-safety and allocates all items needed for a netconn
\r
682 when the netconn is created.
\r
684 2007-11-30 Simon Goldschmidt
\r
685 * udp.c: first attempt to fix bug #21655 (DHCP doesn't work reliably with multiple
\r
686 netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed
\r
687 to netif->dhcp->pcb only (if that exists) and not to any other pcb for the same
\r
688 port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address)
\r
690 2007-11-27 Simon Goldschmidt
\r
691 * ip.c: fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by
\r
692 letting ip_route only use netifs that are up.
\r
694 2007-11-27 Simon Goldschmidt
\r
695 * err.h, api_lib.c, api_msg.c, sockets.c: Changed error handling: ERR_MEM, ERR_BUF
\r
696 and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and
\r
697 sockets block most operations once they have seen a fatal error.
\r
699 2007-11-27 Simon Goldschmidt
\r
700 * udp.h, udp.c, dhcp.c: Implemented new function udp_sendto_if which takes the
\r
701 netif to send as an argument (to be able to send on netifs that are down).
\r
703 2007-11-26 Simon Goldschmidt
\r
704 * tcp_in.c: Fixed bug #21582: pcb->acked accounting can be wrong when ACKs
\r
705 arrive out-of-order
\r
707 2007-11-21 Simon Goldschmidt
\r
708 * tcp.h, tcp_out.c, api_msg.c: Fixed bug #20287: tcp_output_nagle sends too early
\r
709 Fixed the nagle algorithm; nagle now also works for all raw API applications
\r
710 and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY'
\r
712 2007-11-12 Frédéric Bernon
\r
713 * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most
\r
714 of the netconn_peer and netconn_addr processing is done inside tcpip_thread
\r
715 context in do_getaddr.
\r
717 2007-11-10 Simon Goldschmidt
\r
718 * etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can
\r
719 happen any time). Now the packet simply isn't enqueued when out of memory.
\r
721 2007-11-01 Simon Goldschmidt
\r
722 * tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or
\r
723 TCP_MSS if that is smaller) as long as no MSS option is received from the
\r
726 2007-11-01 Simon Goldschmidt
\r
727 * tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN)
\r
728 is now based on TCP_MSS instead of pcb->mss (on passive open now effectively
\r
729 sending our configured TCP_MSS instead of the one received).
\r
731 2007-11-01 Simon Goldschmidt
\r
732 * tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was
\r
733 calculated based on the configured TCP_MSS, not on the MSS option received
\r
736 2007-10-09 Simon Goldschmidt
\r
737 * udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too
\r
738 short and also was generated wrong if checksum coverage != tot_len;
\r
739 receive: checksum was calculated wrong if checksum coverage != tot_len
\r
741 2007-10-08 Simon Goldschmidt
\r
742 * mem.c: lfree was not updated in mem_realloc!
\r
744 2007-10-07 Frédéric Bernon
\r
745 * sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential
\r
746 crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT:
\r
747 this change cause an API breakage for netconn_addr, since a parameter
\r
748 type change. Any compiler should cause an error without any changes in
\r
749 yours netconn_peer calls (so, it can't be a "silent change"). It also
\r
750 reduce a little bit the footprint for socket layer (lwip_getpeername &
\r
751 lwip_getsockname use now a common lwip_getaddrname function since
\r
752 netconn_peer & netconn_addr have the same parameters).
\r
754 2007-09-20 Simon Goldschmidt
\r
755 * tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state)
\r
756 by checking tcp_tw_pcbs also
\r
758 2007-09-19 Simon Goldschmidt
\r
759 * icmp.c: Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies)
\r
761 2007-09-15 Mike Kleshov
\r
762 * mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used)
\r
764 2007-09-06 Frédéric Bernon
\r
765 * several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove
\r
766 it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which
\r
767 already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h"
\r
768 if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h.
\r
770 2007-08-30 Frédéric Bernon
\r
771 * igmp.h, igmp.c: Some changes to remove some redundant code, add some traces,
\r
772 and fix some coding style.
\r
774 2007-08-28 Frédéric Bernon
\r
775 * tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any
\r
776 kind of packets. These packets are considered like Ethernet packets (payload
\r
777 pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets
\r
778 are considered like IP packets (payload pointing to iphdr).
\r
780 2007-08-27 Frédéric Bernon
\r
781 * api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error
\r
782 problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state
\r
783 and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT).
\r
785 2007-08-24 Kieran Mansley
\r
786 * inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy
\r
787 compiler (Paradigm C++)
\r
789 2007-08-09 Frédéric Bernon, Bill Florac
\r
790 * stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement.
\r
791 Introduce IGMP_STATS to centralize statistics management.
\r
793 2007-08-09 Frédéric Bernon, Bill Florac
\r
794 * udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast
\r
795 packet on a udp pcb binded on an netif's IP address, and not on "any".
\r
797 2007-08-09 Frédéric Bernon, Bill Florac
\r
798 * igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement.
\r
799 This is mainly on using lookup/lookfor, and some coding styles...
\r
801 2007-07-26 Frédéric Bernon (and "thedoctor")
\r
802 * igmp.c: Fix bug #20595 to accept IGMPv3 "Query" messages.
\r
804 2007-07-25 Simon Goldschmidt
\r
805 * api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if
\r
806 tcp_output fails in tcp_close, the code in do_close_internal gets simpler
\r
807 (tcp_output is called again later from tcp timers).
\r
809 2007-07-25 Simon Goldschmidt
\r
810 * ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old
\r
811 copy_from_pbuf, which illegally modified the given pbuf.
\r
813 2007-07-25 Simon Goldschmidt
\r
814 * tcp_out.c: tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs:
\r
815 changed snd_queuelen++ to snd_queuelen += pbuf_clen(p).
\r
817 2007-07-24 Simon Goldschmidt
\r
818 * api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the
\r
819 correct state (must be CLOSED).
\r
821 2007-07-13 Thomas Taranowski (commited by Jared Grubb)
\r
822 * memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed
\r
823 allocation. It now returns NULL.
\r
825 2007-07-13 Frédéric Bernon
\r
826 * api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in
\r
829 2007-07-13 Frédéric Bernon
\r
830 * api_msg.c: Fix bug #20315: possible memory leak problem if tcp_listen failed,
\r
831 because current code doesn't follow rawapi.txt documentation.
\r
833 2007-07-13 Kieran Mansley
\r
834 * src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in
\r
835 out of sequence processing of received packets
\r
837 2007-07-03 Simon Goldschmidt
\r
838 * nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an
\r
839 assumption is made that this pbuf is in one piece (i.e. not chained). These
\r
840 assumptions clash with the possibility of converting to fully pool-based
\r
841 pbuf implementations, where PBUF_RAM pbufs might be chained.
\r
843 2007-07-03 Simon Goldschmidt
\r
844 * api.h, api_lib.c, api_msg.c: Final fix for bug #20021 and some other problems
\r
845 when closing tcp netconns: removed conn->sem, less context switches when
\r
846 closing, both netconn_close and netconn_delete should safely close tcp
\r
849 2007-07-02 Simon Goldschmidt
\r
850 * ipv4/ip.h, ipv6/ip.h, opt.h, netif.h, etharp.h, ipv4/ip.c, netif.c, raw.c,
\r
851 tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off)
\r
852 to cache ARP table indices with each pcb instead of single-entry cache for
\r
853 the complete stack.
\r
855 2007-07-02 Simon Goldschmidt
\r
856 * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent
\r
857 warnings when assigning to smaller types.
\r
859 2007-06-28 Simon Goldschmidt
\r
860 * tcp_out.c: Added check to prevent tcp_pcb->snd_queuelen from overflowing.
\r
862 2007-06-28 Simon Goldschmidt
\r
863 * tcp.h: Fixed bug #20287: Fixed nagle algorithm (sending was done too early if
\r
864 a segment contained chained pbufs)
\r
866 2007-06-28 Frédéric Bernon
\r
867 * autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute
\r
868 a "pseudo-random" value based on netif's MAC and some autoip fields. It's always
\r
869 possible to define this macro in your own lwipopts.h to always use C library's
\r
870 rand(). Note that autoip_create_rand_addr doesn't use this macro.
\r
872 2007-06-28 Frédéric Bernon
\r
873 * netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option
\r
874 LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications
\r
875 in api_lib/api_msg (use pointers and not type with table, etc...)
\r
877 2007-06-26 Simon Goldschmidt
\r
878 * udp.h: Fixed bug #20259: struct udp_hdr was lacking the packin defines.
\r
880 2007-06-25 Simon Goldschmidt
\r
881 * udp.c: Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload
\r
882 for udp packets with no matching pcb.
\r
884 2007-06-25 Simon Goldschmidt
\r
885 * udp.c: Fixed bug #20220: UDP PCB search in udp_input(): a non-local match
\r
886 could get udp input packets if the remote side matched.
\r
888 2007-06-13 Simon Goldschmidt
\r
889 * netif.c: Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get
\r
890 changed in netif_set_ipaddr if previous netif->ip_addr.addr was 0.
\r
892 2007-06-13 Simon Goldschmidt
\r
893 * api_msg.c: pcb_new sets conn->err if protocol is not implemented
\r
894 -> netconn_new_..() does not allocate a new connection for unsupported
\r
897 2007-06-13 Frédéric Bernon, Simon Goldschmidt
\r
898 * api_lib.c: change return expression in netconn_addr and netconn_peer, because
\r
899 conn->err was reset to ERR_OK without any reasons (and error was lost)...
\r
901 2007-06-13 Frédéric Bernon, Matthias Weisser
\r
902 * opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename
\r
903 MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid
\r
904 some macro names collision with some OS macros.
\r
906 2007-06-11 Simon Goldschmidt
\r
907 * udp.c: UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0,
\r
908 create checksum over the complete packet. On RX, if it's < 8 (and not 0),
\r
909 discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both
\r
912 2007-06-11 Srinivas Gollakota & Oleg Tyshev
\r
913 * tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP flags"
\r
914 where TCP flags wasn't initialized in tcp_keepalive.
\r
916 2007-06-03 Simon Goldschmidt
\r
917 * udp.c: udp_input(): Input pbuf was not freed if pcb had no recv function
\r
918 registered, p->payload was modified without modifying p->len if sending
\r
919 icmp_dest_unreach() (had no negative effect but was definitively wrong).
\r
921 2007-06-03 Simon Goldschmidt
\r
922 * icmp.c: Corrected bug #19937: For responding to an icmp echo request, icmp
\r
923 re-used the input pbuf even if that didn't have enough space to include the
\r
924 link headers. Now the space is tested and a new pbuf is allocated for the
\r
925 echo response packet if the echo request pbuf isn't big enough.
\r
927 2007-06-01 Simon Goldschmidt
\r
928 * sockets.c: Checked in patch #5914: Moved sockopt processing into tcpip_thread.
\r
930 2007-05-23 Frédéric Bernon
\r
931 * api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only
\r
932 allocated by do_listen if success) and netconn_accept errors handling. In
\r
933 most of api_lib functions, we replace some errors checkings like "if (conn==NULL)"
\r
934 by ASSERT, except for netconn_delete.
\r
936 2007-05-23 Frédéric Bernon
\r
937 * api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return
\r
938 an error code if it's impossible to fetch a pbuf on a TCP connection (and not
\r
939 directly close the recvmbox).
\r
941 2007-05-22 Simon Goldschmidt
\r
942 * tcp.c: Fixed bug #1895 (tcp_bind not correct) by introducing a list of
\r
943 bound but unconnected (and non-listening) tcp_pcbs.
\r
945 2007-05-22 Frédéric Bernon
\r
946 * sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only
\r
947 used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of
\r
948 sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features
\r
949 like "sys_timeout" in their application threads.
\r
951 2007-05-22 Frédéric Bernon
\r
952 * api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see
\r
953 which parameters are used by which do_xxx function, and to avoid "misusing"
\r
954 parameters (patch #5938).
\r
956 2007-05-22 Simon Goldschmidt
\r
957 * api_lib.c, api_msg.c, raw.c, api.h, api_msg.h, raw.h: Included patch #5938:
\r
958 changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto
\r
959 is only 8 bits wide. This affects the api, as there, the protocol was
\r
962 2007-05-18 Simon Goldschmidt
\r
963 * memp.c: addition to patch #5913: smaller pointer was returned but
\r
964 memp_memory was the same size -> did not save memory.
\r
966 2007-05-16 Simon Goldschmidt
\r
967 * loopif.c, slipif.c: Fix bug #19729: free pbuf if netif->input() returns
\r
970 2007-05-16 Simon Goldschmidt
\r
971 * api_msg.c, udp.c: If a udp_pcb has a local_ip set, check if it is the same
\r
972 as the one of the netif used for sending to prevent sending from old
\r
973 addresses after a netif address gets changed (partly fixes bug #3168).
\r
975 2007-05-16 Frédéric Bernon
\r
976 * tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work
\r
977 with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in
\r
978 tcpip_init) because we have to be sure that network interfaces are already
\r
979 added (mac filter is updated only in igmp_init for the moment).
\r
981 2007-05-16 Simon Goldschmidt
\r
982 * mem.c, memp.c: Removed semaphores from memp, changed sys_sem_wait calls
\r
983 into sys_arch_sem_wait calls to prevent timers from running while waiting
\r
984 for the heap. This fixes bug #19167.
\r
986 2007-05-13 Simon Goldschmidt
\r
987 * tcp.h, sockets.h, sockets.c: Fixed bug from patch #5865 by moving the defines
\r
988 for socket options (lwip_set/-getsockopt) used with level IPPROTO_TCP from
\r
989 tcp.h to sockets.h.
\r
991 2007-05-07 Simon Goldschmidt
\r
992 * mem.c: Another attempt to fix bug #17922.
\r
994 2007-05-04 Simon Goldschmidt
\r
995 * pbuf.c, pbuf.h, etharp.c: Further update to ARP queueing: Changed pbuf_copy()
\r
996 implementation so that it can be reused (don't allocate the target
\r
997 pbuf inside pbuf_copy()).
\r
999 2007-05-04 Simon Goldschmidt
\r
1000 * memp.c: checked in patch #5913: in memp_malloc() we can return memp as mem
\r
1001 to save a little RAM (next pointer of memp is not used while not in pool).
\r
1004 * sockets.c: Fix ioctl FIONREAD when some data remains from last recv.
\r
1007 2007-04-23 Simon Goldschmidt
\r
1008 * loopif.c, loopif.h, opt.h, src/netif/FILES: fix bug #2595: "loopif results
\r
1009 in NULL reference for incoming TCP packets". Loopif has to be configured
\r
1010 (using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input()
\r
1011 (multithreading environments, e.g. netif->input() = tcpip_input()) or
\r
1012 putting packets on a list that is fed to the stack by calling loopif_poll()
\r
1013 (single-thread / NO_SYS / polling environment where e.g.
\r
1014 netif->input() = ip_input).
\r
1016 2007-04-17 Jonathan Larmour
\r
1017 * pbuf.c: Use s32_t in pbuf_realloc(), as an s16_t can't reliably hold
\r
1018 the difference between two u16_t's.
\r
1019 * sockets.h: FD_SETSIZE needs to match number of sockets, which is
\r
1020 MEMP_NUM_NETCONN in sockets.c right now.
\r
1022 2007-04-12 Jonathan Larmour
\r
1023 * icmp.c: Reset IP header TTL in ICMP ECHO responses (bug #19580).
\r
1025 2007-04-12 Kieran Mansley
\r
1026 * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Modify way the retransmission
\r
1027 timer is reset to fix bug#19434, with help from Oleg Tyshev.
\r
1029 2007-04-11 Simon Goldschmidt
\r
1030 * etharp.c, pbuf.c, pbuf.h: 3rd fix for bug #11400 (arp-queuing): More pbufs than
\r
1031 previously thought need to be copied (everything but PBUF_ROM!). Cleaned up
\r
1032 pbuf.c: removed functions no needed any more (by etharp).
\r
1034 2007-04-11 Kieran Mansley
\r
1035 * inet.c, ip_addr.h, sockets.h, sys.h, tcp.h: Apply patch #5745: Fix
\r
1036 "Constant is long" warnings with 16bit compilers. Contributed by
\r
1037 avatar@mmlab.cse.yzu.edu.tw
\r
1039 2007-04-05 Frédéric Bernon, Jonathan Larmour
\r
1040 * api_msg.c: Fix bug #16830: "err_tcp() posts to connection mailbox when no pend on
\r
1041 the mailbox is active". Now, the post is only done during a connect, and do_send,
\r
1042 do_write and do_join_leave_group don't do anything if a previous error was signaled.
\r
1044 2007-04-03 Frédéric Bernon
\r
1045 * ip.c: Don't set the IP_DF ("Don't fragment") flag in the IP header in IP output
\r
1046 packets. See patch #5834.
\r
1048 2007-03-30 Frédéric Bernon
\r
1049 * api_msg.c: add a "pcb_new" helper function to avoid redundant code, and to add
\r
1050 missing pcb allocations checking (in do_bind, and for each raw_new). Fix style.
\r
1052 2007-03-30 Frédéric Bernon
\r
1053 * most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with
\r
1054 others environment defines (these were too "generic").
\r
1056 2007-03-28 Frédéric Bernon
\r
1057 * api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal pbuf_alloc call
\r
1058 result and can cause a crash. lwip_send now check netbuf_ref result.
\r
1060 2007-03-28 Simon Goldschmidt
\r
1061 * sockets.c Remove "#include <errno.h>" from sockets.c to avoid multiple
\r
1062 definition of macros (in errno.h and lwip/arch.h) if LWIP_PROVIDE_ERRNO is
\r
1063 defined. This is the way it should have been already (looking at
\r
1066 2007-03-28 Kieran Mansley
\r
1067 * opt.h Change default PBUF_POOL_BUFSIZE (again) to accomodate default MSS +
\r
1068 IP and TCP headers *and* physical link headers
\r
1070 2007-03-26 Frédéric Bernon (based on patch from Dmitry Potapov)
\r
1071 * api_lib.c: patch for netconn_write(), fixes a possible race condition which cause
\r
1072 to send some garbage. It is not a definitive solution, but the patch does solve
\r
1073 the problem for most cases.
\r
1075 2007-03-22 Frédéric Bernon
\r
1076 * api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used).
\r
1078 2007-03-22 Frédéric Bernon
\r
1079 * api_lib.c: somes resources couldn't be freed if there was errors during
\r
1080 netconn_new_with_proto_and_callback.
\r
1082 2007-03-22 Frédéric Bernon
\r
1083 * ethernetif.c: update netif->input calls to check return value. In older ports,
\r
1084 it's a good idea to upgrade them, even if before, there could be another problem
\r
1085 (access to an uninitialized mailbox).

1087 2007-03-21 Simon Goldschmidt
\r
1088 * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed
\r
1089 by casting to unsigned).
\r
1091 2007-03-21 Frédéric Bernon
\r
1092 * api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from
\r
1093 api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a
\r
1094 dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call.
\r
1095 Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a
\r
1096 faster and more reliable communication between api_lib and tcpip.
\r
1098 2007-03-21 Frédéric Bernon
\r
1099 * opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0.
\r
1101 2007-03-21 Frédéric Bernon
\r
1102 * api_msg.c, igmp.c, igmp.h: Fix C++ style comments
\r
1104 2007-03-21 Kieran Mansley
\r
1105 * opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS +
\r
1106 IP and TCP headers
\r
1108 2007-03-21 Kieran Mansley
\r
1109 * Fix all uses of pbuf_header to check the return value. In some
\r
1110 cases just assert if it fails as I'm not sure how to fix them, but
\r
1111 this is no worse than before when they would carry on regardless
\r
1114 2007-03-21 Kieran Mansley
\r
1115 * sockets.c, igmp.c, igmp.h, memp.h: Fix C++ style comments and
\r
1116 comment out missing header include in icmp.c
\r
1118 2007-03-20 Frédéric Bernon
\r
1119 * memp.h, stats.c: Fix stats_display function where memp_names table wasn't
\r
1120 synchronized with memp.h.
\r
1122 2007-03-20 Frédéric Bernon
\r
1123 * tcpip.c: Initialize tcpip's mbox, and verify if initialized in tcpip_input,
\r
1124 tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init problem with
\r
1125 network interfaces. Also fix a compiler warning.
\r
1127 2007-03-20 Kieran Mansley
\r
1128 * udp.c: Only try and use pbuf_header() to make space for headers if
\r
1129 not a ROM or REF pbuf.
\r
1131 2007-03-19 Frédéric Bernon
\r
1132 * api_msg.h, api_msg.c, tcpip.h, tcpip.c: Add return types to tcpip_apimsg()
\r
1133 and api_msg_post().
\r
1135 2007-03-19 Frédéric Bernon
\r
1136 * Remove unimplemented "memp_realloc" function from memp.h.
\r
1138 2007-03-11 Simon Goldschmidt
\r
1139 * pbuf.c: checked in patch #5796: pbuf_alloc: len field claculation caused
\r
1140 memory corruption.
\r
1142 2007-03-11 Simon Goldschmidt (based on patch from Dmitry Potapov)
\r
1143 * api_lib.c, sockets.c, api.h, api_msg.h, sockets.h: Fixed bug #19251
\r
1144 (missing `const' qualifier in socket functions), to get more compatible to
\r
1145 standard POSIX sockets.
\r
1147 2007-03-11 Frédéric Bernon (based on patch from Dmitry Potapov)
\r
1148 * sockets.c: Add asserts inside bind, connect and sendto to check input
\r
1149 parameters. Remove excessive set_errno() calls after get_socket(), because
\r
1150 errno is set inside of get_socket(). Move last sock_set_errno() inside
\r
1153 2007-03-09 Simon Goldschmidt
\r
1154 * memp.c: Fixed bug #11400: New etharp queueing introduced bug: memp_memory
\r
1155 was allocated too small.
\r
1157 2007-03-06 Simon Goldschmidt
\r
1158 * tcpip.c: Initialize dhcp timers in tcpip_thread (if LWIP_DHCP) to protect
\r
1159 the stack from concurrent access.
\r
1161 2007-03-06 Frédéric Bernon, Dmitry Potapov
\r
1162 * tcpip.c, ip_frag.c, ethernetif.c: Fix some build problems, and a redundancy
\r
1163 call to "lwip_stats.link.recv++;" in low_level_input() & ethernetif_input().
\r
1165 2007-03-06 Simon Goldschmidt
\r
1166 * ip_frag.c, ip_frag.h: Reduce code size: don't include code in those files
\r
1167 if IP_FRAG == 0 and IP_REASSEMBLY == 0
\r
1169 2007-03-06 Frédéric Bernon, Simon Goldschmidt
\r
1170 * opt.h, ip_frag.h, tcpip.h, tcpip.c, ethernetif.c: add new configuration
\r
1171 option named ETHARP_TCPIP_ETHINPUT, which enable the new tcpip_ethinput.
\r
1172 Allow to do ARP processing for incoming packets inside tcpip_thread
\r
1173 (protecting ARP layer against concurrent access). You can also disable
\r
1174 old code using tcp_input with new define ETHARP_TCPIP_INPUT set to 0.
\r
1175 Older ports have to use tcpip_ethinput.
\r
1177 2007-03-06 Simon Goldschmidt (based on patch from Dmitry Potapov)
\r
1178 * err.h, err.c: fixed compiler warning "initialization dircards qualifiers
\r
1179 from pointer target type"
\r
1181 2007-03-05 Frédéric Bernon
\r
1182 * opt.h, sockets.h: add new configuration options (LWIP_POSIX_SOCKETS_IO_NAMES,
\r
1183 ETHARP_TRUST_IP_MAC, review SO_REUSE)
\r
1185 2007-03-04 Frédéric Bernon
\r
1186 * api_msg.c: Remove some compiler warnings : parameter "pcb" was never
\r
1189 2007-03-04 Frédéric Bernon
\r
1190 * api_lib.c: Fix "[patch #5764] api_lib.c cleanup: after patch #5687" (from
\r
1192 The api_msg struct stay on the stack (not moved to netconn struct).
\r
1194 2007-03-04 Simon Goldschmidt (based on patch from Dmitry Potapov)
\r
1195 * pbuf.c: Fix BUG#19168 - pbuf_free can cause deadlock (if
\r
1196 SYS_LIGHTWEIGHT_PROT=1 & freeing PBUF_RAM when mem_sem is not available)
\r
1197 Also fixed cast warning in pbuf_alloc()
\r
1199 2007-03-04 Simon Goldschmidt
\r
1200 * etharp.c, etharp.h, memp.c, memp.h, opt.h: Fix BUG#11400 - don't corrupt
\r
1201 existing pbuf chain when enqueuing multiple pbufs to a pending ARP request
\r
1203 2007-03-03 Frédéric Bernon
\r
1204 * udp.c: remove obsolete line "static struct udp_pcb *pcb_cache = NULL;"
\r
1205 It is static, and never used in udp.c except udp_init().
\r
1207 2007-03-02 Simon Goldschmidt
\r
1208 * tcpip.c: Moved call to ip_init(), udp_init() and tcp_init() from
\r
1209 tcpip_thread() to tcpip_init(). This way, raw API connections can be
\r
1210 initialized before tcpip_thread is running (e.g. before OS is started)
\r
1212 2007-03-02 Frédéric Bernon
\r
1213 * rawapi.txt: Fix documentation mismatch with etharp.h about etharp_tmr's call
\r
1216 2007-02-28 Kieran Mansley
\r
1217 * pbuf.c: Fix BUG#17645 - ensure pbuf payload pointer is not moved
\r
1218 outside the region of the pbuf by pbuf_header()
\r
1220 2007-02-28 Kieran Mansley
\r
1221 * sockets.c: Fix BUG#19161 - ensure milliseconds timeout is non-zero
\r
1222 when supplied timeout is also non-zero
\r
1226 2006-12-05 Leon Woestenberg
\r
1227 * CHANGELOG: Mention STABLE-1.2.0 release.
\r
1231 2006-12-01 Christiaan Simons
\r
1232 * mem.h, opt.h: Added MEM_LIBC_MALLOC option.
\r
1233 Note this is a workaround. Currently I have no other options left.
\r
1235 2006-10-26 Christiaan Simons (accepted patch by Jonathan Larmour)
\r
1236 * ipv4/ip_frag.c: rename MAX_MTU to IP_FRAG_MAX_MTU and move define
\r
1237 to include/lwip/opt.h.
\r
1238 * ipv4/lwip/ip_frag.h: Remove unused IP_REASS_INTERVAL.
\r
1239 Move IP_REASS_MAXAGE and IP_REASS_BUFSIZE to include/lwip/opt.h.
\r
1240 * opt.h: Add above new options.
\r
1242 2006-08-18 Christiaan Simons
\r
1243 * tcp_{in,out}.c: added SNMP counters.
\r
1244 * ipv4/ip.c: added SNMP counters.
\r
1245 * ipv4/ip_frag.c: added SNMP counters.
\r
1247 2006-08-08 Christiaan Simons
\r
1248 * etharp.{c,h}: added etharp_find_addr() to read
\r
1249 (stable) ethernet/IP address pair from ARP table
\r
1251 2006-07-14 Christiaan Simons
\r
1252 * mib_structs.c: added
\r
1253 * include/lwip/snmp_structs.h: added
\r
1254 * netif.{c,h}, netif/ethernetif.c: added SNMP statistics to netif struct
\r
1256 2006-07-06 Christiaan Simons
\r
1257 * snmp/asn1_{enc,dec}.c added
\r
1258 * snmp/mib2.c added
\r
1259 * snmp/msg_{in,out}.c added
\r
1260 * include/lwip/snmp_asn1.h added
\r
1261 * include/lwip/snmp_msg.h added
\r
1262 * doc/snmp_agent.txt added
\r
1264 2006-03-29 Christiaan Simons
\r
1265 * inet.c, inet.h: Added platform byteswap support.
\r
1266 Added LWIP_PLATFORM_BYTESWAP define (defaults to 0) and
\r
1267 optional LWIP_PLATFORM_HTONS(), LWIP_PLATFORM_HTONL() macros.
\r
1271 2006-11-30 Christiaan Simons
\r
1272 * dhcp.c: Fixed false triggers of request_timeout.
\r
1274 2006-11-28 Christiaan Simons
\r
1275 * netif.c: In netif_add() fixed missing clear of ip_addr, netmask, gw and flags.
\r
1277 2006-10-11 Christiaan Simons
\r
1278 * api_lib.c etharp.c, ip.c, memp.c, stats.c, sys.{c,h} tcp.h:
\r
1279 Partially accepted patch #5449 for ANSI C compatibility / build fixes.
\r
1280 * ipv4/lwip/ip.h ipv6/lwip/ip.h: Corrected UDP-Lite protocol
\r
1281 identifier from 170 to 136 (bug #17574).
\r
1283 2006-10-10 Christiaan Simons
\r
1284 * api_msg.c: Fixed Nagle algorithm as reported by Bob Grice.
\r
1286 2006-08-17 Christiaan Simons
\r
1287 * udp.c: Fixed bug #17200, added check for broadcast
\r
1288 destinations for PCBs bound to a unicast address.
\r
1290 2006-08-07 Christiaan Simons
\r
1291 * api_msg.c: Flushing TCP output in do_close() (bug #15926).
\r
1293 2006-06-27 Christiaan Simons
\r
1294 * api_msg.c: Applied patch for cold case (bug #11135).
\r
1295 In accept_function() ensure newconn->callback is always initialized.
\r
1297 2006-06-15 Christiaan Simons
\r
1298 * mem.h: added MEM_SIZE_F alias to fix an ancient cold case (bug #1748),
\r
1299 facilitate printing of mem_size_t and u16_t statistics.
\r
1301 2006-06-14 Christiaan Simons
\r
1302 * api_msg.c: Applied patch #5146 to handle allocation failures
\r
1303 in accept() by Kevin Lawson.
\r
1305 2006-05-26 Christiaan Simons
\r
1306 * api_lib.c: Removed conn->sem creation and destruction
\r
1307 from netconn_write() and added sys_sem_new to netconn_new_*.
\r
1311 2006-03-03 Christiaan Simons
\r
1312 * ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap
\r
1313 access and added pbuf_alloc() return value checks.
\r
1315 2006-01-01 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1316 * tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is
\r
1317 now handled by the checksum routine properly.
\r
1319 2006-02-27 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1320 * pbuf.c: Fix alignment; pbuf_init() would not work unless
\r
1321 pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.)
\r
1323 2005-12-20 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1324 * tcp.c: Remove PCBs which stay in LAST_ACK state too long. Patch
\r
1325 submitted by Mitrani Hiroshi.
\r
1327 2005-12-15 Christiaan Simons
\r
1328 * inet.c: Disabled the added summing routine to preserve code space.
\r
1330 2005-12-14 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1331 * tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
\r
1332 Added Curt McDowell's optimized checksumming routine for future
\r
1333 inclusion. Need to create test case for unaliged, aligned, odd,
\r
1334 even length combination of cases on various endianess machines.
\r
1336 2005-12-09 Christiaan Simons
\r
1337 * inet.c: Rewrote standard checksum routine in proper portable C.
\r
1339 2005-11-25 Christiaan Simons
\r
1340 * udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
\r
1341 * *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
\r
1342 u32_t, s32_t typedefs. This solves most debug word-length assumes.
\r
1344 2005-07-17 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1345 * inet.c: Fixed unaligned 16-bit access in the standard checksum
\r
1346 routine by Peter Jolasson.
\r
1347 * slipif.c: Fixed implementation assumption of single-pbuf datagrams.
\r
1349 2005-02-04 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1350 * tcp_out.c: Fixed uninitialized 'queue' referenced in memerr branch.
\r
1351 * tcp_{out|in}.c: Applied patch fixing unaligned access.
\r
1353 2005-01-04 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1354 * pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement.
\r
1356 2005-01-03 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1357 * udp.c: UDP pcb->recv() was called even when it was NULL.
\r
1361 2004-12-28 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1362 * etharp.*: Disabled multiple packets on the ARP queue.
\r
1363 This clashes with TCP queueing.
\r
1365 2004-11-28 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1366 * etharp.*: Fixed race condition from ARP request to ARP timeout.
\r
1367 Halved the ARP period, doubled the period counts.
\r
1368 ETHARP_MAX_PENDING now should be at least 2. This prevents
\r
1369 the counter from reaching 0 right away (which would allow
\r
1370 too little time for ARP responses to be received).
\r
1372 2004-11-25 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1373 * dhcp.c: Decline messages were not multicast but unicast.
\r
1374 * etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
\r
1375 Do not try hard to insert arbitrary packet's source address,
\r
1376 etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
\r
1377 etharp_query() now always DOES call ETHARP_TRY_HARD so that users
\r
1378 querying an address will see it appear in the cache (DHCP could
\r
1379 suffer from this when a server invalidly gave an in-use address.)
\r
1380 * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
\r
1381 comparing network addresses (identifiers), not the network masks
\r
1383 * ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
\r
1384 IP address actually belongs to the network of the given interface.
\r
1386 2004-11-24 Kieran Mansley <kjm25@cam.ac.uk>
\r
1387 * tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.
\r
1389 (STABLE-1_1_0-RC1)
\r
1391 2004-10-16 Kieran Mansley <kjm25@cam.ac.uk>
\r
1392 * tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
\r
1393 even if one is already pending, if the rcv_wnd is above a threshold
\r
1394 (currently TCP_WND/2). This avoids waiting for a timer to expire to send a
\r
1395 delayed ACK in order to open the window if the stack is only receiving data.
\r
1397 2004-09-12 Kieran Mansley <kjm25@cam.ac.uk>
\r
1398 * tcp*.*: Retransmit time-out handling improvement by Sam Jansen.
\r
1400 2004-08-20 Tony Mountifield <tony@softins.co.uk>
\r
1401 * etharp.c: Make sure the first pbuf queued on an ARP entry
\r
1402 is properly ref counted.
\r
1404 2004-07-27 Tony Mountifield <tony@softins.co.uk>
\r
1405 * debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
\r
1406 warnings about comparison.
\r
1407 * pbuf.c: Stopped compiler complaining of empty if statement
\r
1408 when LWIP_DEBUGF() empty. Closed an unclosed comment.
\r
1409 * tcp.c: Stopped compiler complaining of empty if statement
\r
1410 when LWIP_DEBUGF() empty.
\r
1411 * ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
\r
1412 * inet.c: Added a couple of casts to quiet the compiler.
\r
1413 No need to test isascii(c) before isdigit(c) or isxdigit(c).
\r
1415 2004-07-22 Tony Mountifield <tony@softins.co.uk>
\r
1416 * inet.c: Made data types consistent in inet_ntoa().
\r
1417 Added casts for return values of checksum routines, to pacify compiler.
\r
1418 * ip_frag.c, tcp_out.c, sockets.c, pbuf.c
\r
1419 Small corrections to some debugging statements, to pacify compiler.
\r
1421 2004-07-21 Tony Mountifield <tony@softins.co.uk>
\r
1422 * etharp.c: Removed spurious semicolon and added missing end-of-comment.
\r
1423 * ethernetif.c Updated low_level_output() to match prototype for
\r
1424 netif->linkoutput and changed low_level_input() similarly for consistency.
\r
1425 * api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
\r
1426 of raw_recv() in raw.h and so avoid compiler error.
\r
1427 * sockets.c: Added trivial (int) cast to keep compiler happier.
\r
1428 * ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.
\r
1434 2004-07-05 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1435 * sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure
\r
1436 your cc.h file defines this either 1 or 0. If non-defined,
\r
1438 * .c: Added <string.h> and <errno.h> includes where used.
\r
1439 * etharp.c: Made some array indices unsigned.
\r
1441 2004-06-27 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1442 * netif.*: Added netif_set_up()/down().
\r
1443 * dhcp.c: Changes to restart program flow.
\r
1445 2004-05-07 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1446 * etharp.c: In find_entry(), instead of a list traversal per candidate, do a
\r
1447 single-pass lookup for different candidates. Should exploit locality.
\r
1449 2004-04-29 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1450 * tcp*.c: Cleaned up source comment documentation for Doxygen processing.
\r
1451 * opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC.
\r
1452 * etharp.c: update_arp_entry() only adds new ARP entries when adviced to by
\r
1453 the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option.
\r
1457 2004-04-27 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1458 * etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution
\r
1459 suggested by Timmy Brolin. Fix for 32-bit processors that cannot access
\r
1460 non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix
\r
1461 is to prefix the 14-bit Ethernet headers with two padding bytes.
\r
1463 2004-04-23 Leon Woestenberg <leon.woestenberg@gmx.net>
\r
1464 * ip_addr.c: Fix in the ip_addr_isbroadcast() check.
\r
1465 * etharp.c: Fixed the case where the packet that initiates the ARP request
\r
1466 is not queued, and gets lost. Fixed the case where the packets destination
\r
1467 address is already known; we now always queue the packet and perform an ARP
\r
1474 * Fixed TCP bug for SYN_SENT to ESTABLISHED state transition.
\r
1475 * Fixed TCP bug in dequeueing of FIN from out of order segment queue.
\r
1476 * Fixed two possible NULL references in rare cases.
\r
1482 * Fixed DHCP which did not include the IP address in DECLINE messages.
\r
1486 * etharp.c has been hauled over a bit.
\r
1492 * Fixed TCP bug induced by bad window resizing with unidirectional TCP traffic.
\r
1493 * Packets sent from ARP queue had invalid source hardware address.
\r
1497 * Pass-by ARP requests do now update the cache.
\r
1501 * No longer dependent on ctype.h.
\r
1502 * New socket options.
\r
1503 * Raw IP pcb support.
\r
1509 * Some debug formatters and casts fixed.
\r
1510 * Numereous fixes in PPP.
\r
1514 * DEBUGF now is LWIP_DEBUGF
\r
1515 * pbuf_dechain() has been re-enabled.
\r
1516 * Mentioned the changed use of CVS branches in README.
\r
1522 * Fixed pool pbuf memory leak in pbuf_alloc().
\r
1523 Occured if not enough PBUF_POOL pbufs for a packet pbuf chain.
\r
1524 Reported by Savin Zlobec.
\r
1526 * PBUF_POOL chains had their tot_len field not set for non-first
\r
1527 pbufs. Fixed in pbuf_alloc().
\r
1531 * Added PPP stack contributed by Marc Boucher
\r
1535 * Now drops short packets for ICMP/UDP/TCP protocols. More robust.
\r
1537 * ARP queueuing now queues the latest packet instead of the first.
\r
1538 This is the RFC recommended behaviour, but can be overridden in
\r
1545 * TCP has been fixed to deal with the new use of the pbuf->ref
\r
1548 * DHCP dhcp_inform() crash bug fixed.
\r
1552 * Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
\r
1553 pbuf_refresh(). This has sped up pbuf pool operations considerably.
\r
1554 Implemented by David Haas.
\r
1560 * The packet buffer implementation has been enhanced to support
\r
1561 zero-copy and copy-on-demand for packet buffers which have their
\r
1562 payloads in application-managed memory.
\r
1563 Implemented by David Haas.
\r
1565 Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
\r
1566 if an outgoing packet can be directly sent on the link, or perform
\r
1567 a copy-on-demand when necessary.
\r
1569 The application can safely assume the packet is sent, and the RAM
\r
1570 is available to the application directly after calling udp_send()
\r
1571 or similar function.
\r
1575 * ARP_QUEUEING should now correctly work for all cases, including
\r
1577 Implemented by Leon Woestenberg.
\r
1581 * IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
\r
1582 to a '0.0.0.0' IP address.
\r
1584 * The packet buffer implementation is changed. The pbuf->ref counter
\r
1585 meaning has changed, and several pbuf functions have been
\r
1586 adapted accordingly.
\r
1588 * netif drivers have to be changed to set the hardware address length field
\r
1589 that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).
\r
1590 See the contrib/ports/c16x cs8900 driver as a driver example.
\r
1592 * netif's have a dhcp field that must be initialized to NULL by the driver.
\r
1593 See the contrib/ports/c16x cs8900 driver as a driver example.
\r
1595 (0.5.x) This file has been unmaintained up to 0.6.1. All changes are
\r
1596 logged in CVS but have not been explained here.
\r
1598 (0.5.3) Changes since version 0.5.2
\r
1602 * memp_malloc(MEMP_API_MSG) could fail with multiple application
\r
1603 threads because it wasn't protected by semaphores.
\r
1607 * struct ip_addr now packed.
\r
1609 * The name of the time variable in arp.c has been changed to ctime
\r
1610 to avoid conflicts with the time() function.
\r
1612 (0.5.2) Changes since version 0.5.1
\r
1616 * A new TCP function, tcp_tmr(), now handles both TCP timers.
\r
1620 * A bug in tcp_parseopt() could cause the stack to hang because of a
\r
1621 malformed TCP option.
\r
1623 * The address of new connections in the accept() function in the BSD
\r
1624 socket library was not handled correctly.
\r
1626 * pbuf_dechain() did not update the ->tot_len field of the tail.
\r
1628 * Aborted TCP connections were not handled correctly in all
\r
1633 * All protocol header structs are now packed.
\r
1635 * The ->len field in the tcp_seg structure now counts the actual
\r
1636 amount of data, and does not add one for SYN and FIN segments.
\r
1638 (0.5.1) Changes since version 0.5.0
\r
1642 * Possible to run as a user process under Linux.
\r
1644 * Preliminary support for cross platform packed structs.
\r
1646 * ARP timer now implemented.
\r
1650 * TCP output queue length was badly initialized when opening
\r
1653 * TCP delayed ACKs were not sent correctly.
\r
1655 * Explicit initialization of BSS segment variables.
\r
1657 * read() in BSD socket library could drop data.
\r
1659 * Problems with memory alignment.
\r
1661 * Situations when all TCP buffers were used could lead to
\r
1664 * TCP MSS option wasn't parsed correctly.
\r
1666 * Problems with UDP checksum calculation.
\r
1668 * IP multicast address tests had endianess problems.
\r
1670 * ARP requests had wrong destination hardware address.
\r
1674 * struct eth_addr changed from u16_t[3] array to u8_t[6].
\r
1676 * A ->linkoutput() member was added to struct netif.
\r
1678 * TCP and UDP ->dest_* struct members where changed to ->remote_*.
\r
1680 * ntoh* macros are now null definitions for big endian CPUs.
\r
1682 (0.5.0) Changes since version 0.4.2
\r
1686 * Redesigned operating system emulation layer to make porting easier.
\r
1688 * Better control over TCP output buffers.
\r
1690 * Documenation added.
\r
1694 * Locking issues in buffer management.
\r
1696 * Bugfixes in the sequential API.
\r
1698 * IP forwarding could cause memory leakage. This has been fixed.
\r
1702 * Directory structure somewhat changed; the core/ tree has been
\r
1705 (0.4.2) Changes since version 0.4.1
\r
1709 * Experimental ARP implementation added.
\r
1711 * Skeleton Ethernet driver added.
\r
1713 * Experimental BSD socket API library added.
\r
1717 * In very intense situations, memory leakage could occur. This has
\r
1722 * Variables named "data" and "code" have been renamed in order to
\r
1723 avoid name conflicts in certain compilers.
\r
1725 * Variable++ have in appliciable cases been translated to ++variable
\r
1726 since some compilers generate better code in the latter case.
\r
1728 (0.4.1) Changes since version 0.4
\r
1732 * TCP: Connection attempts time out earlier than data
\r
1733 transmissions. Nagle algorithm implemented. Push flag set on the
\r
1734 last segment in a burst.
\r
1736 * UDP: experimental support for UDP-Lite extensions.
\r
1740 * TCP: out of order segments were in some cases handled incorrectly,
\r
1741 and this has now been fixed. Delayed acknowledgements was broken
\r
1742 in 0.4, has now been fixed. Binding to an address that is in use
\r
1743 now results in an error. Reset connections sometimes hung an
\r
1744 application; this has been fixed.
\r
1746 * Checksum calculation sometimes failed for chained pbufs with odd
\r
1747 lengths. This has been fixed.
\r
1749 * API: a lot of bug fixes in the API. The UDP API has been improved
\r
1750 and tested. Error reporting and handling has been
\r
1751 improved. Logical flaws and race conditions for incoming TCP
\r
1752 connections has been found and removed.
\r
1754 * Memory manager: alignment issues. Reallocating memory sometimes
\r
1755 failed, this has been fixed.
\r
1757 * Generic library: bcopy was flawed and has been fixed.
\r
1761 * API: all datatypes has been changed from generic ones such as
\r
1762 ints, to specified ones such as u16_t. Functions that return
\r
1763 errors now have the correct type (err_t).
\r
1765 * General: A lot of code cleaned up and debugging code removed. Many
\r
1766 portability issues have been fixed.
\r
1768 * The license was changed; the advertising clause was removed.
\r
1772 * Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri
\r
1773 Kosunen, Mikael Caleres, and Frits Wilmink for reporting and
\r
1776 (0.4) Changes since version 0.3.1
\r
1778 * Memory management has been radically changed; instead of
\r
1779 allocating memory from a shared heap, memory for objects that are
\r
1780 rapidly allocated and deallocated is now kept in pools. Allocation
\r
1781 and deallocation from those memory pools is very fast. The shared
\r
1782 heap is still present but is used less frequently.
\r
1784 * The memory, memory pool, and packet buffer subsystems now support
\r
1785 4-, 2-, or 1-byte alignment.
\r
1787 * "Out of memory" situations are handled in a more robust way.
\r
1789 * Stack usage has been reduced.
\r
1791 * Easier configuration of lwIP parameters such as memory usage,
\r
1792 TTLs, statistics gathering, etc. All configuration parameters are
\r
1793 now kept in a single header file "lwipopts.h".
\r
1795 * The directory structure has been changed slightly so that all
\r
1796 architecture specific files are kept under the src/arch
\r
1799 * Error propagation has been improved, both in the protocol modules
\r
1802 * The code for the RTXC architecture has been implemented, tested
\r
1805 * Bugs have been found and corrected in the TCP, UDP, IP, API, and
\r
1806 the Internet checksum modules.
\r
1808 * Bugs related to porting between a 32-bit and a 16-bit architecture
\r
1809 have been found and corrected.
\r
1811 * The license has been changed slightly to conform more with the
\r
1812 original BSD license, including the advertisement clause.
\r
1814 (0.3.1) Changes since version 0.3
\r
1816 * Fix of a fatal bug in the buffer management. Pbufs with allocated
\r
1817 RAM never returned the RAM when the pbuf was deallocated.
\r
1819 * TCP congestion control, window updates and retransmissions did not
\r
1820 work correctly. This has now been fixed.
\r
1822 * Bugfixes in the API.
\r
1824 (0.3) Changes since version 0.2
\r
1826 * New and improved directory structure. All include files are now
\r
1827 kept in a dedicated include/ directory.
\r
1829 * The API now has proper error handling. A new function,
\r
1830 netconn_err(), now returns an error code for the connection in
\r
1833 * Improvements in the memory management subsystem. The system now
\r
1834 keeps a pointer to the lowest free memory block. A new function,
\r
1835 mem_malloc2() tries to allocate memory once, and if it fails tries
\r
1836 to free some memory and retry the allocation.
\r
1838 * Much testing has been done with limited memory
\r
1839 configurations. lwIP now does a better job when overloaded.
\r
1841 * Some bugfixes and improvements to the buffer (pbuf) subsystem.
\r
1843 * Many bugfixes in the TCP code:
\r
1845 - Fixed a bug in tcp_close().
\r
1847 - The TCP receive window was incorrectly closed when out of
\r
1848 sequence segments was received. This has been fixed.
\r
1850 - Connections are now timed-out of the FIN-WAIT-2 state.
\r
1852 - The initial congestion window could in some cases be too
\r
1853 large. This has been fixed.
\r
1855 - The retransmission queue could in some cases be screwed up. This
\r
1858 - TCP RST flag now handled correctly.
\r
1860 - Out of sequence data was in some cases never delivered to the
\r
1861 application. This has been fixed.
\r
1863 - Retransmitted segments now contain the correct acknowledgment
\r
1864 number and advertised window.
\r
1866 - TCP retransmission timeout backoffs are not correctly computed
\r
1867 (ala BSD). After a number of retransmissions, TCP now gives up
\r
1870 * TCP connections now are kept on three lists, one for active
\r
1871 connections, one for listening connections, and one for
\r
1872 connections that are in TIME-WAIT. This greatly speeds up the fast
\r
1873 timeout processing for sending delayed ACKs.
\r
1875 * TCP now provides proper feedback to the application when a
\r
1876 connection has been successfully set up.
\r
1878 * More comments have been added to the code. The code has also been
\r
1879 somewhat cleaned up.
\r
1881 (0.2) Initial public release.
