* TODO: The lwIP source code makes some invalid assumptions on processor |
---|
4 |
word-length, storage sizes and alignment. See the mailing lists for |
---|
5 |
problems with exoteric (/DSP) architectures showing these problems. |
---|
6 |
We still have to fix some of these issues neatly. |
---|
7 |
|
---|
8 |
* TODO: the PPP code is broken in a few ways. There are namespace |
---|
9 |
collisions on BSD systems and many assumptions on word-length |
---|
10 |
(sizeof(int)). In ppp.c an assumption is made on the availability of |
---|
11 |
a thread subsystem. Either PPP needs to be moved to contrib/ports/??? |
---|
12 |
or rearranged to be more generic. |

---|
31 |
* inet_chksum.c: Allow choice of one of the sample algorithms to be |
---|
32 |
made from lwipopts.h. Fix comment on how to override LWIP_CHKSUM. |
---|
33 |
|
---|
34 |
2008-01-22 Frédéric Bernon |
---|
35 |
* tcp.c, tcp_in.c, tcp.h, opt.h: Rename LWIP_CALCULATE_EFF_SEND_MSS in |
---|
36 |
TCP_CALCULATE_EFF_SEND_MSS to have coherent TCP options names. |
---|
37 |
|
---|
38 |
2008-01-14 Frédéric Bernon |
---|
39 |
* rawapi.txt, api_msg.c, tcp.c, tcp_in.c, tcp.h: changes for task #7675 "Enable |
---|
40 |
to refuse data on a TCP_EVENT_RECV call". Important, behavior changes for the |
---|
41 |
tcp_recv callback (see rawapi.txt). |
---|
42 |
|
---|
43 |
2008-01-14 Frédéric Bernon, Marc Chaland |
---|
44 |
* ip.c: Integrate patch #6369" ip_input : checking before realloc". |
---|
45 |
|
---|
46 |
2008-01-12 Frédéric Bernon |
---|
47 |
* tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field |
---|
48 |
netconn::sem per netconn::op_completed like suggested for the task #7490 |
---|
49 |
"Add return value to sys_mbox_post". |
---|
50 |
|
---|
51 |
2008-01-12 Frédéric Bernon |
---|
52 |
* api_msg.c, opt.h: replace DEFAULT_RECVMBOX_SIZE per DEFAULT_TCP_RECVMBOX_SIZE, |
---|
53 |
DEFAULT_UDP_RECVMBOX_SIZE and DEFAULT_RAW_RECVMBOX_SIZE (to optimize queues |
---|
54 |
sizes), like suggested for the task #7490 "Add return value to sys_mbox_post". |
---|
55 |
|
---|
56 |
2008-01-10 Frédéric Bernon |
---|
57 |
* tcpip.h, tcpip.c: add tcpip_callback_with_block function for the task #7490 |
---|
58 |
"Add return value to sys_mbox_post". tcpip_callback is always defined as |
---|
59 |
"blocking" ("block" parameter = 1). |
---|
60 |
|
---|
61 |
2008-01-10 Frédéric Bernon |
---|
62 |
* tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field |
---|
63 |
netconn::mbox (sys_mbox_t) per netconn::sem (sys_sem_t) for the task #7490 |
---|
64 |
"Add return value to sys_mbox_post". |
---|
65 |
|
---|
66 |
2008-01-05 Frédéric Bernon |
---|
67 |
* sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h, opt.h: |
---|
68 |
Introduce changes for task #7490 "Add return value to sys_mbox_post" with some |
---|
69 |
modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which |
---|
70 |
indicate the number of pointers query by the mailbox. There is three defines |
---|
71 |
in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the |
---|
72 |
netconn::acceptmbox. Port maintainers, you can decide to just add this new |
---|
73 |
parameter in your implementation, but to ignore it to keep the previous behavior. |
---|
74 |
The new sys_mbox_trypost function return a value to know if the mailbox is |
---|
75 |
full or if the message is posted. Take a look to sys_arch.txt for more details. |
---|
76 |
This new function is used in tcpip_input (so, can be called in an interrupt |
---|
77 |
context since the function is not blocking), and in recv_udp and recv_raw. |
---|
78 |
|
---|
79 |
2008-01-04 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour |
---|
80 |
* rawapi.txt, api.h, api_lib.c, api_msg.h, api_msg.c, sockets.c, tcp.h, tcp.c, |
---|
81 |
tcp_in.c, init.c, opt.h: rename backlog options with TCP_ prefix, limit the |
---|
82 |
"backlog" parameter in an u8_t, 0 is interpreted as "smallest queue", add |
---|
83 |
documentation in the rawapi.txt file. |
---|
84 |
|
---|
85 |
2007-12-31 Kieran Mansley (based on patch from Per-Henrik Lundbolm) |
---|
86 |
* tcp.c, tcp_in.c, tcp_out.c, tcp.h: Add TCP persist timer |
---|
87 |
|
---|
88 |
2007-12-31 Frédéric Bernon, Luca Ceresoli |
---|
89 |
* autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP packets |
---|
90 |
in autoip". The change in etharp_raw could be removed, since all calls to |
---|
91 |
etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be |
---|
92 |
wrong in the future. |
---|
93 |
|
---|
94 |
2007-12-30 Frédéric Bernon, Tom Evans |
---|
95 |
* ip.c: Fix bug #21846 "LwIP doesn't appear to perform any IP Source Address |
---|
96 |
Filtering" reported by Tom Evans. |
---|
97 |
|
---|
98 |
2007-12-21 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour |
---|
99 |
* tcp.h, opt.h, api.h, api_msg.h, tcp.c, tcp_in.c, api_lib.c, api_msg.c, |
---|
100 |
sockets.c, init.c: task #7252: Implement TCP listen backlog: Warning: raw API |
---|
101 |
applications have to call 'tcp_accepted(pcb)' in their accept callback to |
---|
102 |
keep accepting new connections. |
---|
103 |
|
---|
104 |
2007-12-13 Frédéric Bernon |
---|
105 |
* api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum dns_result" |
---|
106 |
by err_t type. Add a new err_t code "ERR_INPROGRESS". |
---|
107 |
|
---|
108 |
2007-12-12 Frédéric Bernon |
---|
109 |
* dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles |
---|
110 |
are the one which have ram usage. |
---|
111 |
|
---|
112 |
2007-12-05 Frédéric Bernon |
---|
113 |
* netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static |
---|
114 |
set of variables (=0) or a local one (=1). In this last case, your port should |
---|
115 |
provide a function "struct hostent* sys_thread_hostent( struct hostent* h)" |
---|
116 |
which have to do a copy of "h" and return a pointer ont the "per-thread" copy. |
---|
117 |
|
---|
118 |
2007-12-03 Simon Goldschmidt |
---|
119 |
* ip.c: ip_input: check if a packet is for inp first before checking all other |
---|
120 |
netifs on netif_list (speeds up packet receiving in most cases) |
---|
121 |
|
---|
122 |
2007-11-30 Simon Goldschmidt |
---|
123 |
* udp.c, raw.c: task #7497: Sort lists (pcb, netif, ...) for faster access |
---|
124 |
UDP: move a (connected) pcb selected for input to the front of the list of |
---|
125 |
pcbs so that it is found faster next time. Same for RAW pcbs that have eaten |
---|
126 |
a packet. |
---|
127 |
|
---|
128 |
2007-11-28 Simon Goldschmidt |
---|
129 |
* etharp.c, stats.c, stats.h, opt.h: Introduced ETHARP_STATS |
---|
130 |
|
---|
131 |
2007-11-25 Simon Goldschmidt |
---|
132 |
* dhcp.c: dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy |
---|
133 |
algorithm. |
---|
134 |
|
---|
135 |
2007-11-24 Simon Goldschmidt |
---|
136 |
* netdb.h, netdb.c, sockets.h/.c: Moved lwip_gethostbyname from sockets.c |
---|
137 |
to the new file netdb.c; included lwip_getaddrinfo. |
---|
138 |
|
---|
139 |
2007-11-21 Simon Goldschmidt |
---|
140 |
* tcp.h, opt.h, tcp.c, tcp_in.c: implemented calculating the effective send-mss |
---|
141 |
based on the MTU of the netif used to send. Enabled by default. Disable by |
---|
142 |
setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21492. |
---|
143 |
|
---|
144 |
2007-11-19 Frédéric Bernon |
---|
145 |
* api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name |
---|
146 |
received match the name query), implement DNS_USES_STATIC_BUF (the place where |
---|
147 |
copy dns payload to parse the response), return an error if there is no place |
---|
148 |
for a new query, and fix some minor problems. |
---|
149 |
|
---|
150 |
2007-11-16 Simon Goldschmidt |
---|
151 |
* new files: ipv4/inet.c, ipv4/inet_chksum.c, ipv6/inet6.c |
---|
152 |
removed files: core/inet.c, core/inet6.c |
---|
153 |
Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into |
---|
154 |
inet and chksum part; changed includes in all lwIP files as appropriate |
---|
155 |
|
---|
156 |
2007-11-16 Simon Goldschmidt |
---|
157 |
* api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential |
---|
158 |
dns resolver function for netconn api (netconn_gethostbyname) and socket api |
---|
159 |
(gethostbyname/gethostbyname_r). |
---|
160 |
|
---|
161 |
2007-11-15 Jim Pettinato, Frédéric Bernon |
---|
162 |
* opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name |
---|
163 |
requests with RAW api interface. Initialization is done in lwip_init() with |
---|
164 |
build time options. DNS timer is added in tcpip_thread context. DHCP can set |
---|
165 |
DNS server ip addresses when options are received. You need to set LWIP_DNS=1 |
---|
166 |
in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get |
---|
167 |
some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo" |
---|
168 |
list with points to improve. |
---|
169 |
|
---|
170 |
2007-11-06 Simon Goldschmidt |
---|
171 |
* opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly |
---|
172 |
enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status |
---|
173 |
for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined. |
---|
174 |
|
---|
175 |
2007-11-06 Simon Goldschmidt |
---|
176 |
* api.h, api_msg.h and dependent files: Task #7410: Removed the need to include |
---|
177 |
core header files in api.h (ip/tcp/udp/raw.h) to hide the internal |
---|
178 |
implementation from netconn api applications. |
---|
179 |
|
---|
180 |
2007-11-03 Frédéric Bernon |
---|
181 |
* api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP & |
---|
182 |
RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled |
---|
183 |
by default). Netconn API users can use the netconn_recv_bufsize macro to access |
---|
184 |
it. This is a first release which have to be improve for TCP. Note it used the |
---|
185 |
netconn::recv_avail which need to be more "thread-safe" (note there is already |
---|
186 |
the problem for FIONREAD with lwip_ioctl/ioctlsocket). |
---|
187 |
|
---|
188 |
2007-11-01 Frédéric Bernon, Marc Chaland |
---|
189 |
* sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c: |
---|
190 |
Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api |
---|
191 |
layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api |
---|
192 |
layer. This option enable to delayed TCP PUSH flag on multiple "write" calls. |
---|
193 |
Note that previous "copy" parameter for "write" APIs is now called "apiflags". |
---|
194 |
|
---|
195 |
2007-10-24 Frédéric Bernon |
---|
196 |
* api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than |
---|
197 |
TCP_EVENT_xxx macros to get a code more readable. It could also help to remove |
---|
198 |
some code (like we have talk in "patch #5919 : Create compile switch to remove |
---|
199 |
select code"), but it could be done later. |
---|
200 |
|
---|
201 |
2007-10-08 Simon Goldschmidt |
---|
202 |
* many files: Changed initialization: many init functions are not needed any |
---|
203 |
more since we now rely on the compiler initializing global and static |
---|
204 |
variables to zero! |
---|
205 |
|
---|
206 |
2007-10-06 Simon Goldschmidt |
---|
207 |
* ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY |
---|
208 |
to enqueue the received pbufs so that multiple packets can be reassembled |
---|
209 |
simultaneously and no static reassembly buffer is needed. |
---|
210 |
|
---|
211 |
2007-10-05 Simon Goldschmidt |
---|
212 |
* tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so |
---|
213 |
all netifs (or ports) can use it. |
---|
214 |
|
---|
215 |
2007-10-05 Frédéric Bernon |
---|
216 |
* netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the |
---|
217 |
common function to reduce a little bit the footprint (for all functions using |
---|
218 |
only the "netif" parameter). |
---|
219 |
|
---|
220 |
2007-10-03 Frédéric Bernon |
---|
221 |
* netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down, |
---|
222 |
netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce |
---|
223 |
a little bit the footprint (for all functions using only the "netif" parameter). |
---|
224 |
|
---|
225 |
2007-09-15 Frédéric Bernon |
---|
226 |
* udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF |
---|
227 |
option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for |
---|
228 |
netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for |
---|
229 |
IP_MULTICAST_TTL and IP_MULTICAST_IF. |
---|
230 |
|
---|
231 |
2007-09-10 Frédéric Bernon |
---|
232 |
* snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles |
---|
233 |
even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime() |
---|
234 |
each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can |
---|
235 |
decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but |
---|
236 |
call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime() |
---|
237 |
or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro. |
---|
238 |
This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside |
---|
239 |
snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only |
---|
240 |
when it's queried (any direct call to "sysuptime" is changed by a call to |
---|
241 |
snmp_get_sysuptime). |
---|
242 |
|
---|
243 |
2007-09-09 Frédéric Bernon, Bill Florac |
---|
244 |
* igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP, |
---|
245 |
and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags |
---|
246 |
if you want IGMP on an interface. igmp_stop() is now called inside netif_remove(). |
---|
247 |
igmp_report_groups() is now called inside netif_set_link_up() (need to have |
---|
248 |
LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait |
---|
249 |
the next query message to receive the matching multicast streams). |
---|
250 |
|
---|
251 |
2007-09-08 Frédéric Bernon |
---|
252 |
* sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains |
---|
253 |
IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change). |
---|
254 |
Use this new field to access to common pcb fields (ttl, tos, so_options, etc...). |
---|
255 |
Enable to access to these fields with LWIP_TCP=0. |
---|
256 |
|
---|
257 |
2007-09-05 Frédéric Bernon |
---|
258 |
* udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h, |
---|
259 |
ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option |
---|
260 |
LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default). |
---|
261 |
Be careful, disabling ICMP make your product non-compliant to RFC1122, but |
---|
262 |
help to reduce footprint, and to reduce "visibility" on the Internet. |
---|
263 |
|
---|
264 |
2007-09-05 Frédéric Bernon, Bill Florac |
---|
265 |
* opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list |
---|
266 |
for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new |
---|
267 |
parameters have to be provided: a task name, and a task stack size. For this |
---|
268 |
one, since it's platform dependant, you could define the best one for you in |
---|
269 |
your lwipopts.h. For port maintainers, you can just add these new parameters |
---|
270 |
in your sys_arch.c file, and but it's not mandatory, use them in your OS |
---|
271 |
specific functions. |
---|
272 |
|
---|
273 |
2007-09-05 Frédéric Bernon |
---|
274 |
* inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings |
---|
275 |
inside init.c for task #7142 "Sanity check user-configurable values". |
---|
276 |
|
---|
277 |
2007-09-04 Frédéric Bernon, Bill Florac |
---|
278 |
* igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by |
---|
279 |
memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the |
---|
280 |
value). It will avoid potential fragmentation problems, use a counter to know |
---|
281 |
how many times a group is used on an netif, and free it when all applications |
---|
282 |
leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity |
---|
283 |
check if LWIP_IGMP!=0). |
---|
284 |
|
---|
285 |
2007-09-03 Frédéric Bernon |
---|
286 |
* igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement". |
---|
287 |
Initialize igmp_mac_filter to NULL in netif_add (this field should be set in |
---|
288 |
the netif's "init" function). Use the "imr_interface" field (for socket layer) |
---|
289 |
and/or the "interface" field (for netconn layer), for join/leave operations. |
---|
290 |
The igmp_join/leavegroup first parameter change from a netif to an ipaddr. |
---|
291 |
This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany). |
---|
292 |
|
---|
293 |
2007-08-30 Frédéric Bernon |
---|
294 |
* Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions |
---|
295 |
from api/api_lib". Now netbuf API is independant of netconn, and can be used |
---|
296 |
with other API (application based on raw API, or future "socket2" API). Ports |
---|
297 |
maintainers just have to add src/api/netbuf.c in their makefile/projects. |
---|
298 |
|
---|
299 |
2007-08-30 Frédéric Bernon, Jonathan Larmour |
---|
300 |
* init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check |
---|
301 |
user-configurable values". |
---|
302 |
|
---|
303 |
2007-08-29 Frédéric Bernon |
---|
304 |
* igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start. |
---|
305 |
igmp_start is call inside netif_add. Now, igmp initialization is in the same |
---|
306 |
spirit than the others modules. Modify some IGMP debug traces. |
---|
307 |
|
---|
308 |
2007-08-29 Frédéric Bernon |
---|
309 |
* Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function" |
---|
310 |
Add lwip_init function to regroup all modules initializations, and to provide |
---|
311 |
a place to add code for task #7142 "Sanity check user-configurable values". |
---|
312 |
Ports maintainers should remove direct initializations calls from their code, |
---|
313 |
and add init.c in their makefiles. Note that lwip_init() function is called |
---|
314 |
inside tcpip_init, but can also be used by raw api users since all calls are |
---|
315 |
disabled when matching options are disabled. Also note that their is new options |
---|
316 |
in opt.h, you should configure in your lwipopts.h (they are enabled per default). |
---|
317 |
|
---|
318 |
2007-08-26 Marc Boucher |
---|
319 |
* api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL |
---|
320 |
since they can under certain circumstances be called with an invalid conn |
---|
321 |
pointer after the connection has been closed (and conn has been freed). |
---|
322 |
|
---|
323 |
2007-08-25 Frédéric Bernon (Artem Migaev's Patch) |
---|
324 |
* netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up". |
---|
325 |
Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set. |
---|
326 |
|
---|
327 |
2007-08-22 Frédéric Bernon |
---|
328 |
* netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK |
---|
329 |
to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release. |
---|
330 |
|
---|
331 |
2007-08-22 Frédéric Bernon |
---|
332 |
* tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT & |
---|
333 |
ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the |
---|
334 |
name is tcpip_input (we keep the name of 1.2.0 function). |
---|
335 |
|
---|
336 |
2007-08-17 Jared Grubb |
---|
337 |
* memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool |
---|
338 |
settings into new memp_std.h and optional user file lwippools.h. This adds |
---|
339 |
more dynamic mempools, and allows the user to create an arbitrary number of |
---|
340 |
mempools for mem_malloc. |
---|
341 |
|
---|
342 |
2007-08-16 Marc Boucher |
---|
343 |
* api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function; |
---|
344 |
otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely |
---|
345 |
close the connection. |
---|
346 |
|
---|
347 |
2007-08-16 Marc Boucher |
---|
348 |
* sockets.c: lwip_accept(): check netconn_peer() error return. |
---|
349 |
|
---|
350 |
2007-08-16 Marc Boucher |
---|
351 |
* mem.c, mem.h: Added mem_calloc(). |
---|
352 |
|
---|
353 |
2007-08-16 Marc Boucher |
---|
354 |
* tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT) |
---|
355 |
for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG |
---|
356 |
and starving other message types. |
---|
357 |
Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API |
---|
358 |
|
---|
359 |
2007-08-16 Marc Boucher |
---|
360 |
* pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf |
---|
361 |
type and flgs (later renamed to flags). |
---|
362 |
Use enum pbuf_flag as pbuf_type. Renumber PBUF_FLAG_*. |
---|
363 |
Improved lwip_recvfrom(). TCP push now propagated. |
---|
364 |
|
---|
365 |
2007-08-16 Marc Boucher |
---|
366 |
* ethernetif.c, contrib/ports/various: ethbroadcast now a shared global |
---|
367 |
provided by etharp. |
---|
368 |
|
---|
369 |
2007-08-16 Marc Boucher |
---|
370 |
* ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h, |
---|
371 |
etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c: |
---|
372 |
Added PPPoE support and various PPP improvements. |
---|
373 |
|
---|
374 |
2007-07-25 Simon Goldschmidt |
---|
375 |
* api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial, |
---|
376 |
making netbuf_copy_partial use this function. |
---|
377 |
|
---|
378 |
2007-07-25 Simon Goldschmidt |
---|
379 |
* tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with |
---|
380 |
2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and |
---|
381 |
other stacks. |
---|
382 |
|
---|
383 |
2007-07-13 Jared Grubb (integrated by Frédéric Bernon) |
---|
384 |
* opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add |
---|
385 |
a link callback in the netif struct, and functions to handle it. Be carefull |
---|
386 |
for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c) |
---|
387 |
if you want to be sure to be compatible with future changes... |
---|
388 |
|
---|
389 |
2007-06-30 Frédéric Bernon |
---|
390 |
* sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions. |
---|
391 |
|
---|
392 |
2007-06-21 Simon Goldschmidt |
---|
393 |
* etharp.h, etharp.c: Combined etharp_request with etharp_raw for both |
---|
394 |
LWIP_AUTOIP =0 and =1 to remove redundant code. |
---|
395 |
|
---|
396 |
2007-06-21 Simon Goldschmidt |
---|
397 |
* mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option |
---|
398 |
MEM_USE_POOLS to use 4 pools with different sized elements instead of a |
---|
399 |
heap. This both prevents memory fragmentation and gives a higher speed |
---|
400 |
at the cost of more memory consumption. Turned off by default. |
---|
401 |
|
---|
402 |
2007-06-21 Simon Goldschmidt |
---|
403 |
* api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of |
---|
404 |
netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into |
---|
405 |
int to be able to send a bigger buffer than 64K with one time (mainly |
---|
406 |
used from lwip_send). |
---|
407 |
|
---|
408 |
2007-06-21 Simon Goldschmidt |
---|
409 |
* tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write |
---|
410 |
into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too. |
---|
411 |
|
---|
412 |
2007-06-21 Simon Goldschmidt |
---|
413 |
* api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in |
---|
414 |
netconn_write from api_lib.c to api_msg.c to also prevent multiple context- |
---|
415 |
changes on low memory or empty send-buffer. |
---|
416 |
|
---|
417 |
2007-06-18 Simon Goldschmidt |
---|
418 |
* etharp.c, etharp.h: Changed etharp to use a defined hardware address length |
---|
419 |
of 6 to avoid loading netif->hwaddr_len every time (since this file is only |
---|
420 |
used for ethernet and struct eth_addr already had a defined length of 6). |
---|
421 |
|
---|
422 |
2007-06-17 Simon Goldschmidt |
---|
423 |
* sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets |
---|
424 |
to disable UDP checksum generation on transmit. |
---|
425 |
|
---|
426 |
2007-06-13 Frédéric Bernon, Simon Goldschmidt |
---|
427 |
* debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid |
---|
428 |
pointers or parameters, and let the possibility to redefined it in cc.h. Use |
---|
429 |
this macro to check "conn" parameter in api_msg.c functions. |
---|
430 |
|
---|
431 |
2007-06-11 Simon Goldschmidt |
---|
432 |
* sockets.c, sockets.h: Added UDP lite support for sockets |
---|
433 |
|
---|
434 |
2007-06-10 Simon Goldschmidt |
---|
435 |
* udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled |
---|
436 |
by default) to switch off UDP-Lite support if not needed (reduces udp.c code |
---|
437 |
size) |
---|
438 |
|
---|
439 |
2007-06-09 Dominik Spies (integrated by Frédéric Bernon) |
---|
440 |
* autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h: |
---|
441 |
AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and |
---|
442 |
LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt |
---|
443 |
(see TODO mark in the source code). |
---|
444 |
|
---|
445 |
2007-06-09 Simon Goldschmidt |
---|
446 |
* etharp.h, etharp.c, ethernetif.c: Modified order of parameters for |
---|
447 |
etharp_output() to match netif->output so etharp_output() can be used |
---|
448 |
directly as netif->output to save one function call. |
---|
449 |
|
---|
450 |
2007-06-08 Simon Goldschmidt |
---|
451 |
* netif.h, ethernetif.c, slipif.c, loopif.c: Added define |
---|
452 |
NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables, |
---|
453 |
added initialization of those to ethernetif, slipif and loopif. |
---|
454 |
|
---|
455 |
2007-05-18 Simon Goldschmidt |
---|
456 |
* opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF |
---|
457 |
(defaulting to off for now) that can be set to 0 to send fragmented |
---|
458 |
packets by passing PBUF_REFs down the stack. |
---|
459 |
|
---|
460 |
2007-05-23 Frédéric Bernon |
---|
461 |
* api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP |
---|
462 |
connections, such present in patch #5959. |
---|
463 |
|
---|
464 |
2007-05-23 Frédéric Bernon |
---|
465 |
* api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx |
---|
466 |
code in only one part... |
---|
467 |
|
---|
468 |
2007-05-18 Simon Goldschmidt |
---|
469 |
* opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp |
---|
470 |
elements to overflow. This is achieved by adding some bytes before and after |
---|
471 |
each pool element (increasing their size, of course), filling them with a |
---|
472 |
prominent value and checking them on freeing the element. |
---|
473 |
Set it to 2 to also check every element in every pool each time memp_malloc() |
---|
474 |
or memp_free() is called (slower but more helpful). |
---|
475 |
|
---|
476 |
2007-05-10 Simon Goldschmidt |
---|
477 |
* opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for |
---|
478 |
PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce |
---|
479 |
code size. |
---|
480 |
|
---|
481 |
2007-05-11 Frédéric Bernon |
---|
482 |
* sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c: |
---|
483 |
Include a function pointer instead of a table index in the message to reduce |
---|
484 |
footprint. Disable some part of lwip_send and lwip_sendto if some options are |
---|
485 |
not set (LWIP_TCP, LWIP_UDP, LWIP_RAW). |
---|
486 |
|
---|
487 |
2007-05-10 Simon Goldschmidt |
---|
488 |
* *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus |
---|
489 |
\ extern "C" {' in all header files. Now you can write your application using |
---|
490 |
the lwIP stack in C++ and simply #include the core files. Note I have left |
---|
491 |
out the netif/ppp/*h header files for now, since I don't know which files are |
---|
492 |
included by applications and which are for internal use only. |
---|
493 |
|
---|
494 |
2007-05-09 Simon Goldschmidt |
---|
495 |
* opt.h, *.c/*.h: Included patch #5920: Create define to override C-library |
---|
496 |
memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for |
---|
497 |
situations where some compilers might inline the copy and save a function |
---|
498 |
call. Also replaced all calls to memcpy() with calls to (S)MEMCPY(). |
---|
499 |
|
---|
500 |
2007-05-08 Simon Goldschmidt |
---|
501 |
* mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc()) |
---|
502 |
to be overriden in case the C-library malloc implementation is not protected |
---|
503 |
against concurrent access. |
---|
504 |
|
---|
505 |
2007-05-04 Simon Goldschmidt (Atte Kojo) |
---|
506 |
* etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending |
---|
507 |
multiple packets to the same host. |
---|
508 |
|
---|
509 |
2007-05-04 Frédéric Bernon, Jonathan Larmour |
---|
510 |
* sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible |
---|
511 |
to corrupt remote addr/port connection state". Reduce problems "not enought memory" with |
---|
512 |
netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between |
---|
513 |
sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function. |
---|
514 |
Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct, |
---|
515 |
these fields are now renamed "addr" & "port". |
---|
516 |
|
---|
517 |
2007-04-11 Jonathan Larmour |
---|
518 |
* sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new |
---|
519 |
sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return |
---|
520 |
with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro |
---|
521 |
by the port in sys_arch.h if desired. |
---|
522 |
|
---|
523 |
2007-04-06 Frédéric Bernon, Simon Goldschmidt |
---|
524 |
* opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API |
---|
525 |
allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp |
---|
526 |
clients, using new functions from netifapi.h. Disable as default (no port change to do). |
---|
527 |
|
---|
528 |
2007-04-05 Frédéric Bernon |
---|
529 |
* sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant. |
---|
530 |
|
---|
531 |
2007-04-04 Simon Goldschmidt |
---|
532 |
* arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x) |
---|
533 |
use this for and architecture-independent form to tell the compiler you intentionally |
---|
534 |
are not using this variable. Can be overriden in cc.h. |
---|
535 |
|
---|
536 |
2007-03-28 Frédéric Bernon |
---|
537 |
* opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to |
---|
538 |
define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded |
---|
539 |
string, point on one of your's ethernetif field, or alloc a string you will free yourself). |
---|
540 |
It will be used by DHCP to register a client hostname, but can also be use when you call |
---|
541 |
snmp_set_sysname. |
---|
542 |
|
---|
543 |
2007-03-28 Frédéric Bernon |
---|
544 |
* netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to |
---|
545 |
initialize a network interface's flag with. It tell this interface is an ethernet |
---|
546 |
device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility |
---|
547 |
Support for IPv4" section 4.6) when interface is "up" with netif_set_up(). |
---|
548 |
|
---|
549 |
2007-03-26 Frédéric Bernon, Jonathan Larmour |
---|
550 |
* opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build |
---|
551 |
time if you only use PPP or SLIP. The default is enable. Note we don't have to call |
---|
552 |
etharp_init in your port's initilization sequence if you use tcpip.c, because this call |
---|
553 |
is done in tcpip_init function. |
---|
554 |
|
---|
555 |
2007-03-22 Frédéric Bernon |
---|
556 |
* stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the |
---|
557 |
new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in |
---|
558 |
your lwipopts.h. More, unused counters are not defined in the stats structs, and not |
---|
559 |
display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined |
---|
560 |
but never used. Fix msg_in.c with the correct #if test for a stat display. |

* netif.c, netif.h: Apply patch#4197 with some changes (originator: rireland@hmgsl.com). |
---|
564 |
Provides callback on netif up/down state change. |
---|
565 |
|
---|
566 |
2007-03-11 Frédéric Bernon, Mace Gael, Steve Reynolds |
---|
567 |
* sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, igmp.h, igmp.c, |
---|
568 |
ip.c, netif.h, tcpip.c, opt.h: |
---|
569 |
New configuration option LWIP_IGMP to enable IGMP processing. Based on only one |
---|
570 |
filter per all network interfaces. Declare a new function in netif to enable to |
---|
571 |
control the MAC filter (to reduce lwIP traffic processing). |
---|
572 |
|
---|
573 |
2007-03-11 Frédéric Bernon |
---|
574 |
* tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can |
---|
575 |
be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this |
---|
576 |
unless you know what you're doing (default are RFC1122 compliant). Note |
---|
577 |
that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds. |
---|
578 |
|
---|
579 |
2007-03-08 Frédéric Bernon |
---|
580 |
* tcp.h: Keepalive values can be configured at compile time, but don't change |
---|
581 |
this unless you know what you're doing (default are RFC1122 compliant). |
---|
582 |
|
---|
583 |
2007-03-08 Frédéric Bernon |
---|
584 |
* sockets.c, api.h, api_lib.c, tcpip.c, sys.h, sys.c, err.c, opt.h: |
---|
585 |
Implement LWIP_SO_RCVTIMEO configuration option to enable/disable SO_RCVTIMEO |
---|
586 |
on UDP sockets/netconn. |
---|
587 |
|
---|
588 |
2007-03-08 Simon Goldschmidt |
---|
589 |
* snmp_msg.h, msg_in.c: SNMP UDP ports can be configured at compile time. |
---|
590 |
|
---|
591 |
2007-03-06 Frédéric Bernon |
---|
592 |
* api.h, api_lib.c, sockets.h, sockets.c, tcpip.c, sys.h, sys.c, err.h: |
---|
593 |
Implement SO_RCVTIMEO on UDP sockets/netconn. |
---|
594 |
|
---|
595 |
2007-02-28 Kieran Mansley (based on patch from Simon Goldschmidt) |
---|
596 |
* api_lib.c, tcpip.c, memp.c, memp.h: make API msg structs allocated |
---|
597 |
on the stack and remove the API msg type from memp |
---|
598 |
|
---|
599 |
2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt) |
---|
600 |
* sockets.h, sockets.c: Move socket initialization to new |
---|
601 |
lwip_socket_init() function. |
---|
602 |
NOTE: this changes the API with ports. Ports will have to be |
---|
603 |
updated to call lwip_socket_init() now. |
---|
604 |
|
---|
605 |
2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt) |
---|
606 |
* api_lib.c: Use memcpy in netbuf_copy_partial. |
---|
607 |
|
---|
608 |
|
---|
609 |
++ Bug fixes: |
---|
610 |
|
---|
611 |
2008-03-17 Frédéric Bernon, Ed Kerekes |
---|
612 |
* igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have |
---|
613 |
some problems to fill the IP header on some targets, use now the |
---|
614 |
ip.h macros to do it). |
---|
615 |
|
---|
616 |
2008-03-13 Frédéric Bernon |
---|
617 |
* sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using |
---|
618 |
(lwip_)recvfrom with valid "from" and "fromlen" parameters, on a |
---|
619 |
TCP connection caused a crash. Note that using (lwip_)recvfrom |
---|
620 |
like this is a bit slow and that using (lwip)getpeername is the |
---|
621 |
good lwip way to do it (so, using recv is faster on tcp sockets). |
---|
622 |
|
---|
623 |
2008-03-12 Frédéric Bernon, Jonathan Larmour |
---|
624 |
* api_msg.c, contrib/apps/ping.c: Fix bug #22530 "api_msg.c's |
---|
625 |
recv_raw() does not consume data", and the ping sample (with |
---|
626 |
LWIP_SOCKET=1, the code did the wrong supposition that lwip_recvfrom |
---|
627 |
returned the IP payload, without the IP header). |
---|
628 |
|
---|
629 |
2008-03-04 Jonathan Larmour |
---|
630 |
* mem.c, stats.c, mem.h: apply patch #6414 to avoid compiler errors |
---|
631 |
and/or warnings on some systems where mem_size_t and size_t differ. |
---|
632 |
* pbuf.c, ppp.c: Fix warnings on some systems with mem_malloc. |
---|
633 |
|
---|
634 |
2008-03-04 Kieran Mansley (contributions by others) |
---|
635 |
* Numerous small compiler error/warning fixes from contributions to |
---|
636 |
mailing list after 1.3.0 release candidate made. |
---|
637 |
|
---|
638 |
2008-01-25 Cui hengbin (integrated by Frédéric Bernon) |
---|
639 |
* dns.c: Fix bug #22108 "DNS problem" caused by unaligned structures. |
---|
640 |
|
---|
641 |
2008-01-15 Kieran Mansley |
---|
642 |
* tcp_out.c: BUG20511. Modify persist timer to start when we are |
---|
643 |
prevented from sending by a small send window, not just a zero |
---|
644 |
send window. |
---|
645 |
|
---|
646 |
2008-01-09 Jonathan Larmour |
---|
647 |
* opt.h, ip.c: Rename IP_OPTIONS define to IP_OPTIONS_ALLOWED to avoid |
---|
648 |
conflict with Linux system headers. |
---|
649 |
|
---|
650 |
2008-01-06 Jonathan Larmour |
---|
651 |
* dhcp.c: fix bug #19927: "DHCP NACK problem" by clearing any existing set IP |
---|
652 |
address entirely on receiving a DHCPNAK, and restarting discovery. |
---|
653 |
|
---|
654 |
2007-12-21 Simon Goldschmidt |
---|
655 |
* sys.h, api_lib.c, api_msg.c, sockets.c: fix bug #21698: "netconn->recv_avail |
---|
656 |
is not protected" by using new macros for interlocked access to modify/test |
---|
657 |
netconn->recv_avail. |

659 |
2007-12-20 Kieran Mansley (based on patch from Oleg Tyshev) |
---|
660 |
* tcp_in.c: fix bug# 21535 (nrtx not reset correctly in SYN_SENT state) |
---|
661 |
|
---|
662 |
2007-12-20 Kieran Mansley (based on patch from Per-Henrik Lundbolm) |
---|
663 |
* tcp.c, tcp_in.c, tcp_out.c, tcp.h: fix bug #20199 (better handling |
---|
664 |
of silly window avoidance and prevent lwIP from shrinking the window) |
---|
665 |
|
---|
666 |
2007-12-04 Simon Goldschmidt |
---|
667 |
* tcp.c, tcp_in.c: fix bug #21699 (segment leak in ooseq processing when last |
---|
668 |
data packet was lost): add assert that all segment lists are empty in |
---|
669 |
tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED |
---|
670 |
state from LAST_ACK in tcp_process |
---|
671 |
|
---|
672 |
2007-12-02 Simon Goldschmidt |
---|
673 |
* sockets.h: fix bug #21654: exclude definition of struct timeval from #ifndef FD_SET |
---|
674 |
If including <sys/time.h> for system-struct timeval, LWIP_TIMEVAL_PRIVATE now |
---|
675 |
has to be set to 0 in lwipopts.h |
---|
676 |
|
---|
677 |
2007-12-02 Simon Goldschmidt |
---|
678 |
* api_msg.c, api_lib.c: fix bug #21656 (recvmbox problem in netconn API): always |
---|
679 |
allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen |
---|
680 |
netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox. |
---|
681 |
This is a fix for thread-safety and allocates all items needed for a netconn |
---|
682 |
when the netconn is created. |
---|
683 |
|
---|
684 |
2007-11-30 Simon Goldschmidt |
---|
685 |
* udp.c: first attempt to fix bug #21655 (DHCP doesn't work reliably with multiple |
---|
686 |
netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed |
---|
687 |
to netif->dhcp->pcb only (if that exists) and not to any other pcb for the same |
---|
688 |
port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address) |
---|
689 |
|
---|
690 |
2007-11-27 Simon Goldschmidt |
---|
691 |
* ip.c: fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by |
---|
692 |
letting ip_route only use netifs that are up. |
---|
693 |
|
---|
694 |
2007-11-27 Simon Goldschmidt |
---|
695 |
* err.h, api_lib.c, api_msg.c, sockets.c: Changed error handling: ERR_MEM, ERR_BUF |
---|
696 |
and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and |
---|
697 |
sockets block most operations once they have seen a fatal error. |
---|
698 |
|
---|
699 |
2007-11-27 Simon Goldschmidt |
---|
700 |
* udp.h, udp.c, dhcp.c: Implemented new function udp_sendto_if which takes the |
---|
701 |
netif to send as an argument (to be able to send on netifs that are down). |
---|
702 |
|
---|
703 |
2007-11-26 Simon Goldschmidt |
---|
704 |
* tcp_in.c: Fixed bug #21582: pcb->acked accounting can be wrong when ACKs |
---|
705 |
arrive out-of-order |
---|
706 |
|
---|
707 |
2007-11-21 Simon Goldschmidt |
---|
708 |
* tcp.h, tcp_out.c, api_msg.c: Fixed bug #20287: tcp_output_nagle sends too early |
---|
709 |
Fixed the nagle algorithm; nagle now also works for all raw API applications |
---|
710 |
and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY' |
---|
711 |
|
---|
712 |
2007-11-12 Frédéric Bernon |
---|
713 |
* sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most |
---|
714 |
of the netconn_peer and netconn_addr processing is done inside tcpip_thread |
---|
715 |
context in do_getaddr. |
---|
716 |
|
---|
717 |
2007-11-10 Simon Goldschmidt |
---|
718 |
* etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can |
---|
719 |
happen any time). Now the packet simply isn't enqueued when out of memory. |
---|
720 |
|
---|
721 |
2007-11-01 Simon Goldschmidt |
---|
722 |
* tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or |
---|
723 |
TCP_MSS if that is smaller) as long as no MSS option is received from the |
---|
724 |
remote host. |
---|
725 |
|
---|
726 |
2007-11-01 Simon Goldschmidt |
---|
727 |
* tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN) |
---|
728 |
is now based on TCP_MSS instead of pcb->mss (on passive open now effectively |
---|
729 |
sending our configured TCP_MSS instead of the one received). |
---|
730 |
|
---|
731 |
2007-11-01 Simon Goldschmidt |
---|
732 |
* tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was |
---|
733 |
calculated based on the configured TCP_MSS, not on the MSS option received |
---|
734 |
with SYN+ACK. |
---|
735 |
|
---|
736 |
2007-10-09 Simon Goldschmidt |
---|
737 |
* udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too |
---|
738 |
short and also was generated wrong if checksum coverage != tot_len; |
---|
739 |
receive: checksum was calculated wrong if checksum coverage != tot_len |
---|
740 |
|
---|
741 |
2007-10-08 Simon Goldschmidt |
---|
742 |
* mem.c: lfree was not updated in mem_realloc! |
---|
743 |
|
---|
744 |
2007-10-07 Frédéric Bernon |
---|
745 |
* sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential |
---|
746 |
crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT: |
---|
747 |
this change cause an API breakage for netconn_addr, since a parameter |
---|
748 |
type change. Any compiler should cause an error without any changes in |
---|
749 |
yours netconn_peer calls (so, it can't be a "silent change"). It also |
---|
750 |
reduce a little bit the footprint for socket layer (lwip_getpeername & |
---|
751 |
lwip_getsockname use now a common lwip_getaddrname function since |
---|
752 |
netconn_peer & netconn_addr have the same parameters). |
---|
753 |
|
---|
754 |
2007-09-20 Simon Goldschmidt |
---|
755 |
* tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state) |
---|
756 |
by checking tcp_tw_pcbs also |
---|
757 |
|
---|
758 |
2007-09-19 Simon Goldschmidt |
---|
759 |
* icmp.c: Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies) |
---|
760 |
|
---|
761 |
2007-09-15 Mike Kleshov |
---|
762 |
* mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used) |
---|
763 |
|
---|
764 |
2007-09-06 Frédéric Bernon |
---|
765 |
* several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove |
---|
766 |
it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which |
---|
767 |
already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h" |
---|
768 |
if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h. |
---|
769 |
|
---|
770 |
2007-08-30 Frédéric Bernon |
---|
771 |
* igmp.h, igmp.c: Some changes to remove some redundant code, add some traces, |
---|
772 |
and fix some coding style. |
---|
773 |
|
---|
774 |
2007-08-28 Frédéric Bernon |
---|
775 |
* tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any |
---|
776 |
kind of packets. These packets are considered like Ethernet packets (payload |
---|
777 |
pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets |
---|
778 |
are considered like IP packets (payload pointing to iphdr). |
---|
779 |
|
---|
780 |
2007-08-27 Frédéric Bernon |
---|
781 |
* api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error |
---|
782 |
problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state |
---|
783 |
and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT). |
---|
784 |
|
---|
785 |
2007-08-24 Kieran Mansley |
---|
786 |
* inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy |
---|
787 |
compiler (Paradigm C++) |
---|
788 |
|
---|
789 |
2007-08-09 Frédéric Bernon, Bill Florac |
---|
790 |
* stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement. |
---|
791 |
Introduce IGMP_STATS to centralize statistics management. |
---|
792 |
|
---|
793 |
2007-08-09 Frédéric Bernon, Bill Florac |
---|
794 |
* udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast |
---|
795 |
packet on a udp pcb binded on an netif's IP address, and not on "any". |
---|
796 |
|
---|
797 |
2007-08-09 Frédéric Bernon, Bill Florac |
---|
798 |
* igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement. |
---|
799 |
This is mainly on using lookup/lookfor, and some coding styles... |
---|
800 |
|
---|
801 |
2007-07-26 Frédéric Bernon (and "thedoctor") |
---|
802 |
* igmp.c: Fix bug #20595 to accept IGMPv3 "Query" messages. |
---|
803 |
|
---|
804 |
2007-07-25 Simon Goldschmidt |
---|
805 |
* api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if |
---|
806 |
tcp_output fails in tcp_close, the code in do_close_internal gets simpler |
---|
807 |
(tcp_output is called again later from tcp timers). |
---|
808 |
|
---|
809 |
2007-07-25 Simon Goldschmidt |
---|
810 |
* ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old |
---|
811 |
copy_from_pbuf, which illegally modified the given pbuf. |
---|
812 |
|
---|
813 |
2007-07-25 Simon Goldschmidt |
---|
814 |
* tcp_out.c: tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs: |
---|
815 |
changed snd_queuelen++ to snd_queuelen += pbuf_clen(p). |
---|
816 |
|
---|
817 |
2007-07-24 Simon Goldschmidt |
---|
818 |
* api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the |
---|
819 |
correct state (must be CLOSED). |
---|
820 |
|
---|
821 |
2007-07-13 Thomas Taranowski (commited by Jared Grubb) |
---|
822 |
* memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed |
---|
823 |
allocation. It now returns NULL. |
---|
824 |
|
---|
825 |
2007-07-13 Frédéric Bernon |
---|
826 |
* api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in |
---|
827 |
all error cases. |
---|
828 |
|
---|
829 |
2007-07-13 Frédéric Bernon |
---|
830 |
* api_msg.c: Fix bug #20315: possible memory leak problem if tcp_listen failed, |
---|
831 |
because current code doesn't follow rawapi.txt documentation. |
---|
832 |
|
---|
833 |
2007-07-13 Kieran Mansley |
---|
834 |
* src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in |
---|
835 |
out of sequence processing of received packets |
---|
836 |
|
---|
837 |
2007-07-03 Simon Goldschmidt |
---|
838 |
* nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an |
---|
839 |
assumption is made that this pbuf is in one piece (i.e. not chained). These |
---|
840 |
assumptions clash with the possibility of converting to fully pool-based |
---|
841 |
pbuf implementations, where PBUF_RAM pbufs might be chained. |
---|
842 |
|
---|
843 |
2007-07-03 Simon Goldschmidt |
---|
844 |
* api.h, api_lib.c, api_msg.c: Final fix for bug #20021 and some other problems |
---|
845 |
when closing tcp netconns: removed conn->sem, less context switches when |
---|
846 |
closing, both netconn_close and netconn_delete should safely close tcp |
---|
847 |
connections. |
---|
848 |
|
---|
849 |
2007-07-02 Simon Goldschmidt |
---|
850 |
* ipv4/ip.h, ipv6/ip.h, opt.h, netif.h, etharp.h, ipv4/ip.c, netif.c, raw.c, |
---|
851 |
tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off) |
---|
852 |
to cache ARP table indices with each pcb instead of single-entry cache for |
---|
853 |
the complete stack. |
---|
854 |
|
---|
855 |
2007-07-02 Simon Goldschmidt |
---|
856 |
* tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent |
---|
857 |
warnings when assigning to smaller types. |
---|
858 |
|
---|
859 |
2007-06-28 Simon Goldschmidt |
---|
860 |
* tcp_out.c: Added check to prevent tcp_pcb->snd_queuelen from overflowing. |
---|
861 |
|
---|
862 |
2007-06-28 Simon Goldschmidt |
---|
863 |
* tcp.h: Fixed bug #20287: Fixed nagle algorithm (sending was done too early if |
---|
864 |
a segment contained chained pbufs) |
---|
865 |
|
---|
866 |
2007-06-28 Frédéric Bernon |
---|
867 |
* autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute |
---|
868 |
a "pseudo-random" value based on netif's MAC and some autoip fields. It's always |
---|
869 |
possible to define this macro in your own lwipopts.h to always use C library's |
---|
870 |
rand(). Note that autoip_create_rand_addr doesn't use this macro. |
---|
871 |
|
---|
872 |
2007-06-28 Frédéric Bernon |
---|
873 |
* netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option |
---|
874 |
LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications |
---|
875 |
in api_lib/api_msg (use pointers and not type with table, etc...) |
---|
876 |
|
---|
877 |
2007-06-26 Simon Goldschmidt |
---|
878 |
* udp.h: Fixed bug #20259: struct udp_hdr was lacking the packin defines. |
---|
879 |
|
---|
880 |
2007-06-25 Simon Goldschmidt |
---|
881 |
* udp.c: Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload |
---|
882 |
for udp packets with no matching pcb. |
---|
883 |
|
---|
884 |
2007-06-25 Simon Goldschmidt |
---|
885 |
* udp.c: Fixed bug #20220: UDP PCB search in udp_input(): a non-local match |
---|
886 |
could get udp input packets if the remote side matched. |
---|
887 |
|
---|
888 |
2007-06-13 Simon Goldschmidt |
---|
889 |
* netif.c: Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get |
---|
890 |
changed in netif_set_ipaddr if previous netif->ip_addr.addr was 0. |
---|
891 |
|
---|
892 |
2007-06-13 Simon Goldschmidt |
---|
893 |
* api_msg.c: pcb_new sets conn->err if protocol is not implemented |
---|
894 |
-> netconn_new_..() does not allocate a new connection for unsupported |
---|
895 |
protocols. |
---|
896 |
|
---|
897 |
2007-06-13 Frédéric Bernon, Simon Goldschmidt |
---|
898 |
* api_lib.c: change return expression in netconn_addr and netconn_peer, because |
---|
899 |
conn->err was reset to ERR_OK without any reasons (and error was lost)... |
---|
900 |
|
---|
901 |
2007-06-13 Frédéric Bernon, Matthias Weisser |
---|
902 |
* opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename |
---|
903 |
MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid |
---|
904 |
some macro names collision with some OS macros. |
---|
905 |
|
---|
906 |
2007-06-11 Simon Goldschmidt |
---|
907 |
* udp.c: UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0, |
---|
908 |
create checksum over the complete packet. On RX, if it's < 8 (and not 0), |
---|
909 |
discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both |
---|
910 |
UDP & UDP Lite. |
---|
911 |
|
---|
912 |
2007-06-11 Srinivas Gollakota & Oleg Tyshev |
---|
913 |
* tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP flags" |
---|
914 |
where TCP flags wasn't initialized in tcp_keepalive. |
---|
915 |
|
---|
916 |
2007-06-03 Simon Goldschmidt |
---|
917 |
* udp.c: udp_input(): Input pbuf was not freed if pcb had no recv function |
---|
918 |
registered, p->payload was modified without modifying p->len if sending |
---|
919 |
icmp_dest_unreach() (had no negative effect but was definitively wrong). |
---|
920 |
|
---|
921 |
2007-06-03 Simon Goldschmidt |
---|
922 |
* icmp.c: Corrected bug #19937: For responding to an icmp echo request, icmp |
---|
923 |
re-used the input pbuf even if that didn't have enough space to include the |
---|
924 |
link headers. Now the space is tested and a new pbuf is allocated for the |
---|
925 |
echo response packet if the echo request pbuf isn't big enough. |
---|
926 |
|
---|
927 |
2007-06-01 Simon Goldschmidt |
---|
928 |
* sockets.c: Checked in patch #5914: Moved sockopt processing into tcpip_thread. |
---|
929 |
|
---|
930 |
2007-05-23 Frédéric Bernon |
---|
931 |
* api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only |
---|
932 |
allocated by do_listen if success) and netconn_accept errors handling. In |
---|
933 |
most of api_lib functions, we replace some errors checkings like "if (conn==NULL)" |
---|
934 |
by ASSERT, except for netconn_delete. |
---|
935 |
|
---|
936 |
2007-05-23 Frédéric Bernon |
---|
937 |
* api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return |
---|
938 |
an error code if it's impossible to fetch a pbuf on a TCP connection (and not |
---|
939 |
directly close the recvmbox). |
---|
940 |
|
---|
941 |
2007-05-22 Simon Goldschmidt |
---|
942 |
* tcp.c: Fixed bug #1895 (tcp_bind not correct) by introducing a list of |
---|
943 |
bound but unconnected (and non-listening) tcp_pcbs. |
---|
944 |
|
---|
945 |
2007-05-22 Frédéric Bernon |
---|
946 |
* sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only |
---|
947 |
used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of |
---|
948 |
sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features |
---|
949 |
like "sys_timeout" in their application threads. |
---|
950 |
|
---|
951 |
2007-05-22 Frédéric Bernon |
---|
952 |
* api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see |
---|
953 |
which parameters are used by which do_xxx function, and to avoid "misusing" |
---|
954 |
parameters (patch #5938). |
---|
955 |
|
---|
956 |
2007-05-22 Simon Goldschmidt |
---|
957 |
* api_lib.c, api_msg.c, raw.c, api.h, api_msg.h, raw.h: Included patch #5938: |
---|
958 |
changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto |
---|
959 |
is only 8 bits wide. This affects the api, as there, the protocol was |
---|
960 |
u16_t, too. |
---|
961 |
|
---|
962 |
2007-05-18 Simon Goldschmidt |
---|
963 |
* memp.c: addition to patch #5913: smaller pointer was returned but |
---|
964 |
memp_memory was the same size -> did not save memory. |
---|
965 |
|
---|
966 |
2007-05-16 Simon Goldschmidt |
---|
967 |
* loopif.c, slipif.c: Fix bug #19729: free pbuf if netif->input() returns |
---|
968 |
!= ERR_OK. |
---|
969 |
|
---|
970 |
2007-05-16 Simon Goldschmidt |
---|
971 |
* api_msg.c, udp.c: If a udp_pcb has a local_ip set, check if it is the same |
---|
972 |
as the one of the netif used for sending to prevent sending from old |
---|
973 |
addresses after a netif address gets changed (partly fixes bug #3168). |
---|
974 |
|
---|
975 |
2007-05-16 Frédéric Bernon |
---|
976 |
* tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work |
---|
977 |
with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in |
---|
978 |
tcpip_init) because we have to be sure that network interfaces are already |
---|
979 |
added (mac filter is updated only in igmp_init for the moment). |
---|
980 |
|
---|
981 |
2007-05-16 Simon Goldschmidt |
---|
982 |
* mem.c, memp.c: Removed semaphores from memp, changed sys_sem_wait calls |
---|
983 |
into sys_arch_sem_wait calls to prevent timers from running while waiting |
---|
984 |
for the heap. This fixes bug #19167. |
---|
985 |
|
---|
986 |
2007-05-13 Simon Goldschmidt |
---|
987 |
* tcp.h, sockets.h, sockets.c: Fixed bug from patch #5865 by moving the defines |
---|
988 |
for socket options (lwip_set/-getsockopt) used with level IPPROTO_TCP from |
---|
989 |
tcp.h to sockets.h. |
---|
990 |
|
---|
991 |
2007-05-07 Simon Goldschmidt |
---|
992 |
* mem.c: Another attempt to fix bug #17922. |
---|
993 |
|
---|
994 |
2007-05-04 Simon Goldschmidt |
---|
995 |
* pbuf.c, pbuf.h, etharp.c: Further update to ARP queueing: Changed pbuf_copy() |
---|
996 |
implementation so that it can be reused (don't allocate the target |
---|
997 |
pbuf inside pbuf_copy()). |
---|
998 |
|
---|
999 |
2007-05-04 Simon Goldschmidt |
---|
1000 |
* memp.c: checked in patch #5913: in memp_malloc() we can return memp as mem |
---|
1001 |
to save a little RAM (next pointer of memp is not used while not in pool). |
---|
1002 |
|
---|
1003 |
2007-05-03 "maq" |
---|
1004 |
* sockets.c: Fix ioctl FIONREAD when some data remains from last recv. |
---|
1005 |
(patch #3574). |
---|
1006 |
|
---|
1007 |
2007-04-23 Simon Goldschmidt |
---|
1008 |
* loopif.c, loopif.h, opt.h, src/netif/FILES: fix bug #2595: "loopif results |
---|
1009 |
in NULL reference for incoming TCP packets". Loopif has to be configured |
---|
1010 |
(using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input() |
---|
1011 |
(multithreading environments, e.g. netif->input() = tcpip_input()) or |
---|
1012 |
putting packets on a list that is fed to the stack by calling loopif_poll() |
---|
1013 |
(single-thread / NO_SYS / polling environment where e.g. |
---|
1014 |
netif->input() = ip_input). |
---|
1015 |
|
---|
1016 |
2007-04-17 Jonathan Larmour |
---|
1017 |
* pbuf.c: Use s32_t in pbuf_realloc(), as an s16_t can't reliably hold |
---|
1018 |
the difference between two u16_t's. |
---|
1019 |
* sockets.h: FD_SETSIZE needs to match number of sockets, which is |
---|
1020 |
MEMP_NUM_NETCONN in sockets.c right now. |
---|
1021 |
|
---|
1022 |
2007-04-12 Jonathan Larmour |
---|
1023 |
* icmp.c: Reset IP header TTL in ICMP ECHO responses (bug #19580). |
---|
1024 |
|
---|
1025 |
2007-04-12 Kieran Mansley |
---|
1026 |
* tcp.c, tcp_in.c, tcp_out.c, tcp.h: Modify way the retransmission |
---|
1027 |
timer is reset to fix bug#19434, with help from Oleg Tyshev. |
---|
1028 |
|
---|
1029 |
2007-04-11 Simon Goldschmidt |
---|
1030 |
* etharp.c, pbuf.c, pbuf.h: 3rd fix for bug #11400 (arp-queuing): More pbufs than |
---|
1031 |
previously thought need to be copied (everything but PBUF_ROM!). Cleaned up |
---|
1032 |
pbuf.c: removed functions no needed any more (by etharp). |
---|
1033 |
|
---|
1034 |
2007-04-11 Kieran Mansley |
---|
1035 |
* inet.c, ip_addr.h, sockets.h, sys.h, tcp.h: Apply patch #5745: Fix |
---|
1036 |
"Constant is long" warnings with 16bit compilers. Contributed by |
---|
1037 |
avatar@mmlab.cse.yzu.edu.tw |
---|
1038 |
|
---|
1039 |
2007-04-05 Frédéric Bernon, Jonathan Larmour |
---|
1040 |
* api_msg.c: Fix bug #16830: "err_tcp() posts to connection mailbox when no pend on |
---|
1041 |
the mailbox is active". Now, the post is only done during a connect, and do_send, |
---|
1042 |
do_write and do_join_leave_group don't do anything if a previous error was signaled. |
---|
1043 |
|
---|
1044 |
2007-04-03 Frédéric Bernon |
---|
1045 |
* ip.c: Don't set the IP_DF ("Don't fragment") flag in the IP header in IP output |
---|
1046 |
packets. See patch #5834. |
---|
1047 |
|
---|
1048 |
2007-03-30 Frédéric Bernon |
---|
1049 |
* api_msg.c: add a "pcb_new" helper function to avoid redundant code, and to add |
---|
1050 |
missing pcb allocations checking (in do_bind, and for each raw_new). Fix style. |
---|
1051 |
|
---|
1052 |
2007-03-30 Frédéric Bernon |
---|
1053 |
* most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with |
---|
1054 |
others environment defines (these were too "generic"). |
---|
1055 |
|
---|
1056 |
2007-03-28 Frédéric Bernon |
---|
1057 |
* api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal pbuf_alloc call |
---|
1058 |
result and can cause a crash. lwip_send now check netbuf_ref result. |
---|
1059 |
|
---|
1060 |
2007-03-28 Simon Goldschmidt |
---|
1061 |
* sockets.c Remove "#include <errno.h>" from sockets.c to avoid multiple |
---|
1062 |
definition of macros (in errno.h and lwip/arch.h) if LWIP_PROVIDE_ERRNO is |
---|
1063 |
defined. This is the way it should have been already (looking at |
---|
1064 |
doc/sys_arch.txt) |
---|
1065 |
|
---|
1066 |
2007-03-28 Kieran Mansley |
---|
1067 |
* opt.h Change default PBUF_POOL_BUFSIZE (again) to accomodate default MSS + |
---|
1068 |
IP and TCP headers *and* physical link headers |
---|
1069 |
|
---|
1070 |
2007-03-26 Frédéric Bernon (based on patch from Dmitry Potapov) |
---|
1071 |
* api_lib.c: patch for netconn_write(), fixes a possible race condition which cause |
---|
1072 |
to send some garbage. It is not a definitive solution, but the patch does solve |
---|
1073 |
the problem for most cases. |
---|
1074 |
|
---|
1075 |
2007-03-22 Frédéric Bernon |
---|
1076 |
* api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used). |
---|
1077 |
|
---|
1078 |
2007-03-22 Frédéric Bernon |
---|
1079 |
* api_lib.c: somes resources couldn't be freed if there was errors during |
---|
1080 |
netconn_new_with_proto_and_callback. |
---|
1081 |
|
---|
1082 |
2007-03-22 Frédéric Bernon |
---|
1083 |
* ethernetif.c: update netif->input calls to check return value. In older ports, |
---|
1084 |
it's a good idea to upgrade them, even if before, there could be another problem |
---|
1085 |
(access to an uninitialized mailbox). |
---|
1086 |
|
---|
1087 |
2007-03-21 Simon Goldschmidt |
---|
1088 |
* sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed |
---|
1089 |
by casting to unsigned). |
---|
1090 |
|
---|
1091 |
2007-03-21 Frédéric Bernon |
---|
1092 |
* api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from |
---|
1093 |
api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a |
---|
1094 |
dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call. |
---|
1095 |
Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a |
---|
1096 |
faster and more reliable communication between api_lib and tcpip. |
---|
1097 |
|
---|
1098 |
2007-03-21 Frédéric Bernon |
---|
1099 |
* opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0. |
---|
1100 |
|
---|
1101 |
2007-03-21 Frédéric Bernon |
---|
1102 |
* api_msg.c, igmp.c, igmp.h: Fix C++ style comments |
---|
1103 |
|
---|
1104 |
2007-03-21 Kieran Mansley |
---|
1105 |
* opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS + |
---|
1106 |
IP and TCP headers |
---|
1107 |
|
---|
1108 |
2007-03-21 Kieran Mansley |
---|
1109 |
* Fix all uses of pbuf_header to check the return value. In some |
---|
1110 |
cases just assert if it fails as I'm not sure how to fix them, but |
---|
1111 |
this is no worse than before when they would carry on regardless |
---|
1112 |
of the failure. |
---|
1113 |
|
---|
1114 |
2007-03-21 Kieran Mansley |
---|
1115 |
* sockets.c, igmp.c, igmp.h, memp.h: Fix C++ style comments and |
---|
1116 |
comment out missing header include in icmp.c |
---|
1117 |
|
---|
1118 |
2007-03-20 Frédéric Bernon |
---|
1119 |
* memp.h, stats.c: Fix stats_display function where memp_names table wasn't |
---|
1120 |
synchronized with memp.h. |
---|
1121 |
|
---|
1122 |
2007-03-20 Frédéric Bernon |
---|
1123 |
* tcpip.c: Initialize tcpip's mbox, and verify if initialized in tcpip_input, |
---|
1124 |
tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init problem with |
---|
1125 |
network interfaces. Also fix a compiler warning. |
---|
1126 |
|
---|
1127 |
2007-03-20 Kieran Mansley |
---|
1128 |
* udp.c: Only try and use pbuf_header() to make space for headers if |
---|
1129 |
not a ROM or REF pbuf. |
---|
1130 |
|
---|

---|
1132 |
* api_msg.h, api_msg.c, tcpip.h, tcpip.c: Add return types to tcpip_apimsg() |
---|
1133 |
and api_msg_post(). |
---|
1134 |
|
---|
1135 |
2007-03-19 Frédéric Bernon |
---|
1136 |
* Remove unimplemented "memp_realloc" function from memp.h. |
---|
1137 |
|
---|
1138 |
2007-03-11 Simon Goldschmidt |
---|
1139 |
* pbuf.c: checked in patch #5796: pbuf_alloc: len field claculation caused |
---|
1140 |
memory corruption. |
---|
1141 |
|
---|
1142 |
2007-03-11 Simon Goldschmidt (based on patch from Dmitry Potapov) |
---|
1143 |
* api_lib.c, sockets.c, api.h, api_msg.h, sockets.h: Fixed bug #19251 |
---|
1144 |
(missing `const' qualifier in socket functions), to get more compatible to |
---|
1145 |
standard POSIX sockets. |
---|
1146 |
|
---|
1147 |
2007-03-11 Frédéric Bernon (based on patch from Dmitry Potapov) |
---|
1148 |
* sockets.c: Add asserts inside bind, connect and sendto to check input |
---|
1149 |
parameters. Remove excessive set_errno() calls after get_socket(), because |
---|
1150 |
errno is set inside of get_socket(). Move last sock_set_errno() inside |
---|
1151 |
lwip_close. |
---|
1152 |
|
---|
1153 |
2007-03-09 Simon Goldschmidt |
---|
1154 |
* memp.c: Fixed bug #11400: New etharp queueing introduced bug: memp_memory |
---|
1155 |
was allocated too small. |
---|
1156 |
|
---|
1157 |
2007-03-06 Simon Goldschmidt |
---|
1158 |
* tcpip.c: Initialize dhcp timers in tcpip_thread (if LWIP_DHCP) to protect |
---|
1159 |
the stack from concurrent access. |
---|
1160 |
|
---|
1161 |
2007-03-06 Frédéric Bernon, Dmitry Potapov |
---|
1162 |
* tcpip.c, ip_frag.c, ethernetif.c: Fix some build problems, and a redundancy |
---|
1163 |
call to "lwip_stats.link.recv++;" in low_level_input() & ethernetif_input(). |
---|
1164 |
|
---|
1165 |
2007-03-06 Simon Goldschmidt |
---|
1166 |
* ip_frag.c, ip_frag.h: Reduce code size: don't include code in those files |
---|
1167 |
if IP_FRAG == 0 and IP_REASSEMBLY == 0 |
---|
1168 |
|
---|
1169 |
2007-03-06 Frédéric Bernon, Simon Goldschmidt |
---|
1170 |
* opt.h, ip_frag.h, tcpip.h, tcpip.c, ethernetif.c: add new configuration |
---|
1171 |
option named ETHARP_TCPIP_ETHINPUT, which enable the new tcpip_ethinput. |
---|
1172 |
Allow to do ARP processing for incoming packets inside tcpip_thread |
---|
1173 |
(protecting ARP layer against concurrent access). You can also disable |
---|
1174 |
old code using tcp_input with new define ETHARP_TCPIP_INPUT set to 0. |
---|
1175 |
Older ports have to use tcpip_ethinput. |
---|
1176 |
|
---|
1177 |
2007-03-06 Simon Goldschmidt (based on patch from Dmitry Potapov) |
---|
1178 |
* err.h, err.c: fixed compiler warning "initialization dircards qualifiers |
---|
1179 |
from pointer target type" |
---|
1180 |
|
---|
1181 |
2007-03-05 Frédéric Bernon |
---|
1182 |
* opt.h, sockets.h: add new configuration options (LWIP_POSIX_SOCKETS_IO_NAMES, |
---|
1183 |
ETHARP_TRUST_IP_MAC, review SO_REUSE) |
---|
1184 |
|
---|
1185 |
2007-03-04 Frédéric Bernon |
---|
1186 |
* api_msg.c: Remove some compiler warnings : parameter "pcb" was never |
---|
1187 |
referenced. |
---|
1188 |
|
---|
1189 |
2007-03-04 Frédéric Bernon |
---|
1190 |
* api_lib.c: Fix "[patch #5764] api_lib.c cleanup: after patch #5687" (from |
---|
1191 |
Dmitry Potapov). |
---|
1192 |
The api_msg struct stay on the stack (not moved to netconn struct). |
---|
1193 |
|
---|
1194 |
2007-03-04 Simon Goldschmidt (based on patch from Dmitry Potapov) |
---|
1195 |
* pbuf.c: Fix BUG#19168 - pbuf_free can cause deadlock (if |
---|
1196 |
SYS_LIGHTWEIGHT_PROT=1 & freeing PBUF_RAM when mem_sem is not available) |
---|
1197 |
Also fixed cast warning in pbuf_alloc() |
---|
1198 |
|
---|
1199 |
2007-03-04 Simon Goldschmidt |
---|
1200 |
* etharp.c, etharp.h, memp.c, memp.h, opt.h: Fix BUG#11400 - don't corrupt |
---|
1201 |
existing pbuf chain when enqueuing multiple pbufs to a pending ARP request |
---|
1202 |
|
---|
1203 |
2007-03-03 Frédéric Bernon |
---|
1204 |
* udp.c: remove obsolete line "static struct udp_pcb *pcb_cache = NULL;" |
---|
1205 |
It is static, and never used in udp.c except udp_init(). |
---|
1206 |
|
---|
1207 |
2007-03-02 Simon Goldschmidt |
---|
1208 |
* tcpip.c: Moved call to ip_init(), udp_init() and tcp_init() from |
---|
1209 |
tcpip_thread() to tcpip_init(). This way, raw API connections can be |
---|
1210 |
initialized before tcpip_thread is running (e.g. before OS is started) |
---|
1211 |
|
---|
1212 |
2007-03-02 Frédéric Bernon |
---|
1213 |
* rawapi.txt: Fix documentation mismatch with etharp.h about etharp_tmr's call |
---|
1214 |
interval. |
---|
1215 |
|
---|
1216 |
2007-02-28 Kieran Mansley |
---|
1217 |
* pbuf.c: Fix BUG#17645 - ensure pbuf payload pointer is not moved |
---|
1218 |
outside the region of the pbuf by pbuf_header() |
---|
1219 |
|
---|
1220 |
2007-02-28 Kieran Mansley |
---|
1221 |
* sockets.c: Fix BUG#19161 - ensure milliseconds timeout is non-zero |
---|
1222 |
when supplied timeout is also non-zero |
---|
1223 |
|
---|

1282 |
|
---|
1283 |
2006-10-10 Christiaan Simons |
---|
1284 |

---|
1285 |
|
---|
1286 |
2006-08-17 Christiaan Simons |
---|
1287 |
* udp.c: Fixed bug #17200, added check for broadcast |
---|
1288 |
destinations for PCBs bound to a unicast address. |
---|
1289 |
|
---|
1290 |
2006-08-07 Christiaan Simons |
---|
1291 |
* api_msg.c: Flushing TCP output in do_close() (bug #15926). |
---|
1292 |
|
---|
1293 |
2006-06-27 Christiaan Simons |
---|
1294 |
* api_msg.c: Applied patch for cold case (bug #11135). |
---|
1295 |
In accept_function() ensure newconn->callback is always initialized. |
---|
1296 |
|
---|
1297 |
2006-06-15 Christiaan Simons |
---|
1298 |
* mem.h: added MEM_SIZE_F alias to fix an ancient cold case (bug #1748), |
---|
1299 |
facilitate printing of mem_size_t and u16_t statistics. |
---|
1300 |
|
---|
1301 |
2006-06-14 Christiaan Simons |
---|
1302 |
* api_msg.c: Applied patch #5146 to handle allocation failures |
---|
1303 |
in accept() by Kevin Lawson. |
---|
1304 |
|
---|
1305 |
2006-05-26 Christiaan Simons |
---|
1306 |
* api_lib.c: Removed conn->sem creation and destruction |
---|
1307 |
from netconn_write() and added sys_sem_new to netconn_new_*. |
---|
1308 |
|
---|
1309 |
(STABLE-1_1_1) |

1310 |
|
---|
1311 |
2006-03-03 Christiaan Simons |
---|
1312 |
* ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap |
---|
1313 |
access and added pbuf_alloc() return value checks. |
---|
1314 |
|
---|
1315 |
2006-01-01 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1316 |
* tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is |
---|
1317 |
now handled by the checksum routine properly. |
---|
1318 |
|
---|
1319 |
2006-02-27 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1320 |
* pbuf.c: Fix alignment; pbuf_init() would not work unless |
---|
1321 |
pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.) |
---|
1322 |
|
---|
1323 |
2005-12-20 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1324 |
* tcp.c: Remove PCBs which stay in LAST_ACK state too long. Patch |
---|
1325 |
submitted by Mitrani Hiroshi. |
---|
1326 |
|
---|
1327 |
2005-12-15 Christiaan Simons |
---|
1328 |
* inet.c: Disabled the added summing routine to preserve code space. |
---|
1329 |
|
---|
1330 |
2005-12-14 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1331 |
* tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson. |
---|
1332 |
Added Curt McDowell's optimized checksumming routine for future |
---|
1333 |
inclusion. Need to create test case for unaliged, aligned, odd, |
---|
1334 |
even length combination of cases on various endianess machines. |
---|
1335 |
|
---|
1336 |
2005-12-09 Christiaan Simons |
---|
1337 |
* inet.c: Rewrote standard checksum routine in proper portable C. |
---|
1338 |
|
---|
1339 |
2005-11-25 Christiaan Simons |
---|
1340 |
* udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only. |
---|
1341 |
* *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t, |
---|
1342 |
u32_t, s32_t typedefs. This solves most debug word-length assumes. |
---|
1343 |
|
---|
1344 |
2005-07-17 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1345 |
* inet.c: Fixed unaligned 16-bit access in the standard checksum |
---|
1346 |
routine by Peter Jolasson. |
---|
1347 |
* slipif.c: Fixed implementation assumption of single-pbuf datagrams. |
---|
1348 |
|
---|
1349 |
2005-02-04 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1350 |
* tcp_out.c: Fixed uninitialized 'queue' referenced in memerr branch. |
---|
1351 |
* tcp_{out|in}.c: Applied patch fixing unaligned access. |
---|
1352 |
|
---|
1353 |
2005-01-04 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1354 |
* pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement. |
---|
1355 |
|
---|
1356 |
2005-01-03 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1357 |
* udp.c: UDP pcb->recv() was called even when it was NULL. |
---|
1358 |
|
---|
1359 |
(STABLE-1_1_0) |
---|
1360 |
|
---|
1361 |
2004-12-28 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1362 |
* etharp.*: Disabled multiple packets on the ARP queue. |
---|
1363 |
This clashes with TCP queueing. |
---|
1364 |
|
---|
1365 |
2004-11-28 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1366 |
* etharp.*: Fixed race condition from ARP request to ARP timeout. |
---|
1367 |
Halved the ARP period, doubled the period counts. |
---|
1368 |
ETHARP_MAX_PENDING now should be at least 2. This prevents |
---|
1369 |
the counter from reaching 0 right away (which would allow |
---|
1370 |
too little time for ARP responses to be received). |
---|
1371 |
|
---|
1372 |
2004-11-25 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1373 |
* dhcp.c: Decline messages were not multicast but unicast. |
---|
1374 |
* etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD. |
---|
1375 |
Do not try hard to insert arbitrary packet's source address, |
---|
1376 |
etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD. |
---|
1377 |
etharp_query() now always DOES call ETHARP_TRY_HARD so that users |
---|
1378 |
querying an address will see it appear in the cache (DHCP could |
---|
1379 |
suffer from this when a server invalidly gave an in-use address.) |
---|
1380 |
* ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are |
---|
1381 |
comparing network addresses (identifiers), not the network masks |
---|
1382 |
themselves. |
---|
1383 |
* ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given |
---|
1384 |
IP address actually belongs to the network of the given interface. |
---|
1385 |
|
---|
1386 |
2004-11-24 Kieran Mansley <kjm25@cam.ac.uk> |
---|
1387 |
* tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state. |
---|
1388 |
|
---|
1389 |
(STABLE-1_1_0-RC1) |
---|
1390 |
|
---|
1391 |
2004-10-16 Kieran Mansley <kjm25@cam.ac.uk> |
---|
1392 |
* tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately, |
---|
1393 |
even if one is already pending, if the rcv_wnd is above a threshold |
---|
1394 |
(currently TCP_WND/2). This avoids waiting for a timer to expire to send a |
---|
1395 |
delayed ACK in order to open the window if the stack is only receiving data. |
---|
1396 |
|
---|
1397 |
2004-09-12 Kieran Mansley <kjm25@cam.ac.uk> |
---|
1398 |
* tcp*.*: Retransmit time-out handling improvement by Sam Jansen. |
---|
1399 |
|
---|
1400 |
2004-08-20 Tony Mountifield <tony@softins.co.uk> |
---|
1401 |
* etharp.c: Make sure the first pbuf queued on an ARP entry |
---|
1402 |
is properly ref counted. |
---|
1403 |
|
---|
1404 |
2004-07-27 Tony Mountifield <tony@softins.co.uk> |
---|
1405 |
* debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler |
---|
1406 |
warnings about comparison. |
---|
1407 |
* pbuf.c: Stopped compiler complaining of empty if statement |
---|
1408 |
when LWIP_DEBUGF() empty. Closed an unclosed comment. |
---|
1409 |
* tcp.c: Stopped compiler complaining of empty if statement |
---|
1410 |
when LWIP_DEBUGF() empty. |
---|
1411 |
* ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons(). |
---|
1412 |
* inet.c: Added a couple of casts to quiet the compiler. |
---|
1413 |
No need to test isascii(c) before isdigit(c) or isxdigit(c). |
---|
1414 |
|
---|
1415 |
2004-07-22 Tony Mountifield <tony@softins.co.uk> |
---|
1416 |
* inet.c: Made data types consistent in inet_ntoa(). |
---|
1417 |
Added casts for return values of checksum routines, to pacify compiler. |
---|
1418 |
* ip_frag.c, tcp_out.c, sockets.c, pbuf.c |
---|
1419 |
Small corrections to some debugging statements, to pacify compiler. |
---|
1420 |
|
---|
1421 |
2004-07-21 Tony Mountifield <tony@softins.co.uk> |
---|
1422 |
* etharp.c: Removed spurious semicolon and added missing end-of-comment. |
---|
1423 |
* ethernetif.c Updated low_level_output() to match prototype for |
---|
1424 |
netif->linkoutput and changed low_level_input() similarly for consistency. |
---|
1425 |
* api_msg.c: Changed recv_raw() from int to u8_t, to match prototype |
---|
1426 |
of raw_recv() in raw.h and so avoid compiler error. |
---|
1427 |
* sockets.c: Added trivial (int) cast to keep compiler happier. |
---|
1428 |
* ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros. |

2004-07-05 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1435 |
* sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure |
---|
1436 |
your cc.h file defines this either 1 or 0. If non-defined, |
---|
1437 |
defaults to 1. |
---|
1438 |
* .c: Added <string.h> and <errno.h> includes where used. |
---|
1439 |
* etharp.c: Made some array indices unsigned. |

1440 |
|
---|
1441 |
2004-06-27 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|

|
---|
1445 |
2004-05-07 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1446 |
* etharp.c: In find_entry(), instead of a list traversal per candidate, do a |
---|
1447 |
single-pass lookup for different candidates. Should exploit locality. |
---|
1448 |
|
---|
1449 |
2004-04-29 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1450 |
* tcp*.c: Cleaned up source comment documentation for Doxygen processing. |
---|
1451 |
* opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC. |
---|
1452 |
* etharp.c: update_arp_entry() only adds new ARP entries when adviced to by |
---|
1453 |
the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option. |

2004-04-27 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1458 |
* etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution |
---|
1459 |
suggested by Timmy Brolin. Fix for 32-bit processors that cannot access |
---|
1460 |
non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix |
---|
1461 |
is to prefix the 14-bit Ethernet headers with two padding bytes. |
---|
1462 |
|
---|
1463 |
2004-04-23 Leon Woestenberg <leon.woestenberg@gmx.net> |
---|
1464 |
* ip_addr.c: Fix in the ip_addr_isbroadcast() check. |
---|
1465 |
* etharp.c: Fixed the case where the packet that initiates the ARP request |
---|
1466 |
is not queued, and gets lost. Fixed the case where the packets destination |
---|
1467 |
address is already known; we now always queue the packet and perform an ARP |
---|
1468 |
request. |

---|
1524 |
Reported by Savin Zlobec. |
---|
1525 |
|
---|
1526 |

1546 |
counter. |

1550 |
++ Changes: |

|
---|
1558 |
++ New features: |

1559 |
|
---|
1560 |
* The packet buffer implementation has been enhanced to support |
---|
1561 |
zero-copy and copy-on-demand for packet buffers which have their |
---|
1562 |
payloads in application-managed memory. |
---|
1563 |
Implemented by David Haas. |
---|
1564 |
|
---|
1565 |
Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy |
---|
1566 |
if an outgoing packet can be directly sent on the link, or perform |
---|
1567 |
a copy-on-demand when necessary. |
---|
1568 |
|
---|
1569 |
The application can safely assume the packet is sent, and the RAM |
---|
1570 |
is available to the application directly after calling udp_send() |
---|
1571 |
or similar function. |
---|

1576 |
PBUF_REF. |
---|
1577 |
Implemented by Leon Woestenberg. |
---|
1578 |
|
---|
1579 |
++ Changes: |
---|
1580 |
|
---|
1581 |
* IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer |
---|
1582 |
to a '0.0.0.0' IP address. |
---|
1583 |
|
---|
1584 |
* The packet buffer implementation is changed. The pbuf->ref counter |
---|
1585 |
meaning has changed, and several pbuf functions have been |
---|
1586 |
adapted accordingly. |
---|
1587 |
|
---|
1588 |
* netif drivers have to be changed to set the hardware address length field |
---|
1589 |
that must be initialized correctly by the driver (hint: 6 for Ethernet MAC). |
---|
1590 |
See the contrib/ports/c16x cs8900 driver as a driver example. |
---|
1591 |
|
---|
1592 |
* netif's have a dhcp field that must be initialized to NULL by the driver. |

1633 |
* All protocol header structs are now packed. |
---|
1634 |
|

1720 |
++ Other changes: |
---|
1721 |
|

1723 |
avoid name conflicts in certain compilers. |
---|
1724 |
|

---|
1729 |
|
---|
1730 |
++ New features: |
---|
1731 |

---|
1741 |
and this has now been fixed. Delayed acknowledgements was broken |
---|
1742 |
in 0.4, has now been fixed. Binding to an address that is in use |
---|
1743 |
now results in an error. Reset connections sometimes hung an |
---|
1744 |
application; this has been fixed. |
---|
1745 |
|
---|
1746 |
* Checksum calculation sometimes failed for chained pbufs with odd |
---|
1747 |
lengths. This has been fixed. |
---|
1748 |
|
---|
1749 |
* API: a lot of bug fixes in the API. The UDP API has been improved |
---|
1750 |
and tested. Error reporting and handling has been |
---|
1751 |
improved. Logical flaws and race conditions for incoming TCP |
---|
1752 |
connections has been found and removed. |
---|
1753 |
|
---|
1754 |
* Memory manager: alignment issues. Reallocating memory sometimes |
---|
1755 |
failed, this has been fixed. |
---|
1756 |
|
---|
1757 |
* Generic library: bcopy was flawed and has been fixed. |
---|
1758 |
|
---|
1759 |
++ Other changes: |

1760 |
|
---|
1761 |
* API: all datatypes has been changed from generic ones such as |
---|
1762 |
ints, to specified ones such as u16_t. Functions that return |
---|
1763 |
errors now have the correct type (err_t). |
---|
1764 |
|
---|
1765 |
* General: A lot of code cleaned up and debugging code removed. Many |
---|
1766 |
portability issues have been fixed. |
---|
1767 |
|
---|
1768 |
* The license was changed; the advertising clause was removed. |
---|
1769 |
|
---|
1770 |
* C64 port added. |

---|
1776 |
(0.4) Changes since version 0.3.1 |
---|
1777 |
|
---|
1778 |
* Memory management has been radically changed; instead of |
---|
1779 |
allocating memory from a shared heap, memory for objects that are |
---|
1780 |
rapidly allocated and deallocated is now kept in pools. Allocation |
---|
1781 |
and deallocation from those memory pools is very fast. The shared |
---|
1782 |
heap is still present but is used less frequently. |
---|
1783 |
|
---|
1784 |
* The memory, memory pool, and packet buffer subsystems now support |
---|
1785 |
4-, 2-, or 1-byte alignment. |
---|
1786 |
|
---|
1787 |
* "Out of memory" situations are handled in a more robust way. |
---|
1788 |
|
---|
1789 |
* Stack usage has been reduced. |
---|
1790 |
|
---|
1791 |
* Easier configuration of lwIP parameters such as memory usage, |
---|
1792 |
TTLs, statistics gathering, etc. All configuration parameters are |
---|
1793 |
now kept in a single header file "lwipopts.h". |
---|
1794 |
|
---|
1795 |
* The directory structure has been changed slightly so that all |
---|
1796 |
architecture specific files are kept under the src/arch |
---|
1797 |
hierarchy. |
---|
1798 |
|
---|
1799 |
* Error propagation has been improved, both in the protocol modules |
---|
1800 |
and in the API. |
---|
1801 |
|
---|
1802 |
* The code for the RTXC architecture has been implemented, tested |
---|
1803 |
and put to use. |
---|
1804 |
|
---|
1805 |
* Bugs have been found and corrected in the TCP, UDP, IP, API, and |
---|
1806 |
the Internet checksum modules. |
---|
1807 |
|
---|
1808 |
* Bugs related to porting between a 32-bit and a 16-bit architecture |
---|
1809 |
have been found and corrected. |
---|
1810 |
|
---|
1811 |
* The license has been changed slightly to conform more with the |
---|
1812 |
original BSD license, including the advertisement clause. |
---|
1813 |
|
---|
1814 |
(0.3.1) Changes since version 0.3 |
---|
1815 |
|
---|
1816 |
* Fix of a fatal bug in the buffer management. Pbufs with allocated |
---|
1817 |
RAM never returned the RAM when the pbuf was deallocated. |
---|
1818 |
|
---|
1819 |
* TCP congestion control, window updates and retransmissions did not |
---|
1820 |
work correctly. This has now been fixed. |
---|
1821 |
|
---|
1822 |
* Bugfixes in the API. |
---|
1823 |
|
---|
1824 |
(0.3) Changes since version 0.2 |
---|
1825 |
|
---|
1826 |
* New and improved directory structure. All include files are now |
---|
1827 |
kept in a dedicated include/ directory. |
---|
1828 |
|
---|
1829 |
* The API now has proper error handling. A new function, |
---|
1830 |
netconn_err(), now returns an error code for the connection in |
---|
1831 |
case of errors. |
---|
1832 |
|
---|
1833 |
* Improvements in the memory management subsystem. The system now |
---|
1834 |
keeps a pointer to the lowest free memory block. A new function, |
---|
1835 |
mem_malloc2() tries to allocate memory once, and if it fails tries |
---|
1836 |
to free some memory and retry the allocation. |
---|
1837 |
|
---|
1838 |
* Much testing has been done with limited memory |
---|
1839 |
configurations. lwIP now does a better job when overloaded. |
---|
1840 |
|
---|
1841 |
* Some bugfixes and improvements to the buffer (pbuf) subsystem. |
---|
1842 |
|
---|
1843 |
* Many bugfixes in the TCP code: |
---|
1844 |
|
---|
1845 |
- Fixed a bug in tcp_close(). |
---|
1846 |
|
---|
1847 |
- The TCP receive window was incorrectly closed when out of |
---|
1848 |
sequence segments was received. This has been fixed. |
---|
1849 |
|
---|
1850 |
- Connections are now timed-out of the FIN-WAIT-2 state. |
---|
1851 |
|
---|
1852 |
- The initial congestion window could in some cases be too |
---|
1853 |
large. This has been fixed. |
---|
1854 |
|
---|
1855 |
- The retransmission queue could in some cases be screwed up. This |
---|
1856 |
has been fixed. |
---|
1857 |
|
---|
1858 |
- TCP RST flag now handled correctly. |
---|
1859 |
|
---|
1860 |
- Out of sequence data was in some cases never delivered to the |
---|
1861 |
application. This has been fixed. |
---|
1862 |
|
---|
1863 |
- Retransmitted segments now contain the correct acknowledgment |
---|
1864 |
number and advertised window. |
---|
1865 |
|
---|
1866 |
- TCP retransmission timeout backoffs are not correctly computed |
---|
1867 |
(ala BSD). After a number of retransmissions, TCP now gives up |
---|
1868 |
the connection. |
---|
1869 |
|
---|
1870 |
* TCP connections now are kept on three lists, one for active |
---|
1871 |
connections, one for listening connections, and one for |
---|
1872 |
connections that are in TIME-WAIT. This greatly speeds up the fast |
---|
1873 |
timeout processing for sending delayed ACKs. |
---|
1874 |
|
---|
1875 |
* TCP now provides proper feedback to the application when a |
---|
1876 |
connection has been successfully set up. |
---|
1877 |
|
---|
1878 |
* More comments have been added to the code. The code has also been |
---|
1879 |
somewhat cleaned up. |
---|
1880 |

---|
1881 |
(0.2) Initial public release. |
