  93. (and therefore on a UDP socket/netconn) when the PCB is bound to IP_ADDR_ANY
  94. 2016-11-16: Dirk Ziegelmeier
  95. * *: Fixed dual-stack behaviour, IPv6 mapped IPv4 support in socket API
  96. 2016-11-14: Joel Cunningham
  97. * tcp_out.c: fixed bug #49533 (start persist timer when unsent seg can't fit
  98. in window)
  99. 2016-11-16: Roberto Barbieri Carrera
  100. * autoip.c: fixed bug #49610 (sometimes AutoIP fails to reuse the same address)
  101. 2016-11-11: Dirk Ziegelmeier
  102. * sockets.c: fixed bug #49578 (dropping multicast membership does not work
  103. with LWIP_SOCKET_OFFSET)
  104. (STABLE-2.0.0)
  105. ++ New features:
  106. 2016-07-27: Simon Goldschmidt
  107. * opt.h, timeouts.h/.c: added LWIP_TIMERS_CUSTOM to override the default
  108. implementation of timeouts
  109. 2016-07-xx: Dirk Ziegelmeier
  110. * Large overhaul of doxygen documentation
  111. 2016-04-05: Simon Goldschmidt
  112. * timers.h/.c: prepare for overriding current timeout implementation: all
  113. stack-internal caclic timers are avaliable in the lwip_cyclic_timers array
  114. 2016-03-23: Simon Goldschmidt
  115. * tcp: call accept-callback with ERR_MEM when allocating a pcb fails on
  116. passive open to inform the application about this error
  117. ATTENTION: applications have to handle NULL pcb in accept callback!
  118. 2016-02-22: Ivan Delamer
  119. * Initial 6LoWPAN support
  120. 2016-02-XX to 2016-03-XX: Dirk Ziegelmeier
  121. * Cleanup TCPIP thread sync methods in a way that it is possibe to use them
  122. in arbitrary code that needs things to be done in TCPIP thread. Used to
  123. decouple netconn, netif, ppp and 6LoWPAN from LWIP core.
  124. 2016-02-XX: Dirk Ziegelmeier
  125. * Implement dual-stack support in RAW, UDP and TCP. Add new IP address
  126. type IPADDR_ANY_TYPE for this. Netconn/Socket API: Dual-stack is
  127. automatically supported when an IPv6 netconn/socket is created.
  128. 2015-12-26: Martin Hentschel and Dirk Ziegelmeier
  129. * Rewrite SNMP agent. SNMPv2c + MIB compiler.
  130. 2015-11-12: Dirk Ziegelmeier
  131. * Decouple SNMP stack from lwIP core and move stack to apps/ directory.
  132. Breaking change: Users have to call snmp_init() now!
  133. 2015-11-12: Dirk Ziegelmeier
  134. * Implement possibility to declare private memory pools. This is useful to
  135. decouple some apps from the core (SNMP stack) or make contrib app usage
  136. simpler (httpserver_raw)
  137. 2015-10-09: Simon Goldschmidt
  138. * started to move "private" header files containing implementation details to
  139. "lwip/priv/" include directory to seperate the API from the implementation.
  140. 2015-10-07: Simon Goldschmidt
  141. * added sntp client as first "supported" application layer protocol implementation
  142. added 'apps' folder
  143. 2015-09-30: Dirk Ziegelmeier
  144. * snmp_structs.h, mib_structs.c, mib2.c: snmp: fixed ugly inheritance
  145. implementation by aggregating the "base class" (struct mib_node) in all
  146. derived node classes to get more type-safe code
  147. 2015-09-23: Simon Goldschmidt
  148. * netif.h/.c, nd6.c: task #13729: Convert netif addresses (IPv4 & IPv6) to
  149. ip_addr_t (so they can be used without conversion/temporary storage)
  150. 2015-09-08: Dirk Ziegelmeier
  151. * snmp: Separate mib2 counter/table callbacks from snmp agent. This both cleans
  152. up the code and should allow integration of a 3rd party agent/mib2. Simple
  153. counters are kept in MIB2_STATS, tree/table change function prototypes moved to
  154. snmp_mib2.h.
  155. 2015-09-03: Simon Goldschmidt
  156. * opt.h, dns.h/.c: DNS/IPv6: added support for AAAA records
  157. 2015-09-01: Simon Goldschmidt
  158. * task #12178: hardware checksum capabilities can be configured per netif
  159. (use NETIF_SET_CHECKSUM_CTRL() in your netif's init function)
  160. 2015-08-30: Simon Goldschmidt
  161. * PBUF_REF with "custom" pbufs is now supported for RX pbufs (see pcapif in
  162. contrib for an example, LWIP_SUPPORT_CUSTOM_PBUF is required)
  163. 2015-08-30: Simon Goldschmidt
  164. * support IPv4 source based routing: define LWIP_HOOK_IP4_ROUTE_SRC to point
  165. to a routing function
  166. 2015-08-05: Simon Goldschmidt
  167. * many files: allow multicast socket options IP_MULTICAST_TTL, IP_MULTICAST_IF
  168. and IP_MULTICAST_LOOP to be used without IGMP
  169. 2015-04-24: Simon Goldschmidt
  170. * dhcp.h/c, autoip.h/.c: added functions dhcp/autoip_supplied_address() to
  171. check for the source of address assignment (replacement for NETIF_FLAG_DHCP)
  172. 2015-04-10: Simon Goldschmidt
  173. * many files: task #13480: added LWIP_IPV4 define - IPv4 can be disabled,
  174. leaving an IPv6-only stack
  175. 2015-04-09: Simon Goldschmidt
  176. * nearly all files: task #12722 (improve IPv4/v6 address handling): renamed
  177. ip_addr_t to ip4_addr_t, renamed ipX_addr_t to ip_addr_t and added IP
  178. version; ip_addr_t is used for all generic IP addresses for the API,
  179. ip(4/6)_addr_t are only used internally or when initializing netifs or when
  180. calling version-related functions
  181. 2015-03-24: Simon Goldschmidt
  182. * opt.h, ip4_addr.h, ip4.c, ip6.c: loopif is not required for loopback traffic
  183. any more but passed through any netif (ENABLE_LOOPBACK has to be enabled)
  184. 2015-03-23: Simon Goldschmidt
  185. * opt.h, etharp.c: with ETHARP_TABLE_MATCH_NETIF== 1, duplicate (Auto)-IP
  186. addresses on multiple netifs should now be working correctly (if correctly
  187. addressed by routing, that is)
  188. 2015-03-23: Simon Goldschmidt
  189. * etharp.c: Stable etharp entries that are about to expire are now refreshed
  190. using unicast to prevent unnecessary broadcast. Only if no answer is received
  191. after 15 seconds, broadcast is used.
  192. 2015-03-06: Philip Gladstone
  193. * netif.h/.c: patch #8359 (Provide utility function to add an IPv6 address to
  194. an interface)
  195. 2015-03-05: Simon Goldschmidt
  196. * netif.c, ip4.c, dhcp.c, autoip.c: fixed bug #37068 (netif up/down handling
  197. is unclear): correclty separated administrative status of a netif (up/down)
  198. from 'valid address' status
  199. ATTENTION: netif_set_up() now always has to be called, even when dhcp/autoip
  200. is used!
  201. 2015-02-26: patch by TabascoEye
  202. * netif.c, udp.h/.c: fixed bug #40753 (re-bind UDP pcbs on change of IP address)
  203. 2015-02-22: chrysn, Simon Goldschmidt
  204. * *.*: Changed nearly all functions taking 'ip(X)_addr_t' pointer to take
  205. const pointers (changed user callbacks: raw_recv_fn, udp_recv_fn; changed
  206. port callbacks: netif_output_fn, netif_igmp_mac_filter_fn)
  207. 2015-02-19: Ivan Delamer
  208. * netif.h, dhcp.c: Removed unused netif flag for DHCP. The preferred way to evaluate
  209. if DHCP is active is through netif->dhcp field.
  210. 2015-02-19: Ivan Delamer
  211. * netif.h, slipif.c, ppp.c: Removed unused netif flag for point to point connections
  212. 2015-02-18: Simon Goldschmidt
  213. * api_lib.c: fixed bug #37958 "netconn API doesn't handle correctly
  214. connections half-closed by peer"
  215. 2015-02-18: Simon Goldschmidt
  216. * tcp.c: tcp_alloc() prefers killing CLOSING/LAST_ACK over active connections
  217. (see bug #39565)
  218. 2015-02-16: Claudius Zingerli, Sergio Caprile
  219. * opt.h, dhcp.h/.c: patch #8361 "Add support for NTP option in DHCP"
  220. 2015-02-14: Simon Goldschmidt
  221. * opt.h, snmp*: added support for write-access community and dedicated
  222. community for sending traps
  223. 2015-02-13: Simon Goldschmidt
  224. * opt.h, memp.c: added hook LWIP_HOOK_MEMP_AVAILABLE() to get informed when
  225. a memp pool was empty and an item is now available
  226. 2015-02-13: Simon Goldschmidt
  227. * opt.h, pbuf.h/.c, etharp.c: Added the option PBUF_LINK_ENCAPSULATION_HLEN to
  228. allocate additional header space for TX on netifs requiring additional headers
  229. 2015-02-12: chrysn
  230. * timers.h/.c: introduce sys_timeouts_sleeptime (returns the time left before
  231. the next timeout is due, for NO_SYS==1)
  232. 2015-02-11: Nick van Ijzendoorn
  233. * opt.h, sockets.h/c: patch #7702 "Include ability to increase the socket number
  234. with defined offset"
  235. 2015-02-11: Frederick Baksik
  236. * opt.h, def.h, others: patch #8423 "arch/perf.h" should be made an optional item
  237. 2015-02-11: Simon Goldschmidt
  238. * api_msg.c, opt.h: started to implement fullduplex sockets/netconns
  239. (note that this is highly unstable yet!)
  240. 2015-01-17: Simon Goldschmidt
  241. * api: allow enabling socket API without (public) netconn API - netconn API is
  242. still used by sockets, but keeping it private (static) should allow better
  243. compiler optimizations
  244. 2015-01-16: Simon Goldschmidt
  245. * tcp_in.c: fixed bug #20506 "Initial congestion window is very small" again
  246. by implementing the calculation formula from RFC3390
  247. 2014-12-10: Simon Goldschmidt
  248. * api: added option LWIP_NETCONN_SEM_PER_THREAD to use a semaphore per thread
  249. instead of using one per netconn and per select call
  250. 2014-12-08: Simon Goldschmidt
  251. * ip6.h: fixed bug #43778: IPv6 header version not set on 16-bit platform
  252. (macro IP6H_VTCFL_SET())
  253. 2014-12-08: Simon Goldschmidt
  254. * icmp.c, ip4.c, pbuf.c, udp.c, pbuf.h: task #11472 Support PBUF_REF for RX
  255. (IPv6 and IPv4/v6 reassembly might not work yet)
  256. 2014-11-06: Simon Goldschmidt
  257. * sockets.c/.h, init.c: lwip_socket_init() is not needed any more
  258. -> compatibility define
  259. 2014-09-16: Simon Goldschmidt
  260. * dns.c, opt.h: reduced ram usage by parsing DNS responses in place
  261. 2014-09-16: Simon Goldschmidt
  262. * pbuf.h/.c: added pbuf_take_at() and pbuf_put_at()
  263. 2014-09-15: Simon Goldschmidt
  264. * dns.c: added source port randomization to make the DNS client more robust
  265. (see bug #43144)
  266. 2013-09-02: Simon Goldschmidt
  267. * arch.h and many other files: added optional macros PACK_STRUCT_FLD_8() and
  268. PACK_STRUCT_FLD_S() to prevent gcc 4 from warning about struct members that
  269. do not need packing
  270. 2013-08-19: Simon Goldschmidt
  271. * netif.h: bug #42998: made NETIF_MAX_HWADDR_LEN overridable for some special
  272. networks
  273. 2013-03-17: Simon Goldschmidt (patch by Ghobad Emadi)
  274. * opt.h, etharp.c: Added LWIP_HOOK_ETHARP_GET_GW to implement IPv4 routing with
  275. multiple gateways
  276. 2013-04-20: Fatih Asici
  277. * opt.h, etharp.h/.c: patch #7993: Added support for transmitting packets
  278. with VLAN headers via hook function LWIP_HOOK_VLAN_SET and to check them
  279. via hook function LWIP_HOOK_VLAN_CHECK
  280. 2014-02-20: Simon Goldschmidt (based on patch by Artem Pisarenko)
  281. * patch #7885: modification of api modules to support FreeRTOS-MPU
  282. (don't pass stack-pointers to other threads)
  283. 2014-02-05: Simon Goldschmidt (patch by "xtian" and "alex_ab")
  284. * patch #6537/#7858: TCP window scaling support
  285. 2014-01-17: Jiri Engelthaler
  286. * icmp, icmp6, opt.h: patch #8027: Completed HW checksuming for IPv4 and
  287. IPv6 ICMP's
  288. 2012-08-22: Sylvain Rochet
  289. * New PPP stack for lwIP, developed in ppp-new branch.
  290. Based from pppd 2.4.5, released 2009-11-17, with huge changes to match
  291. code size and memory requirements for embedded devices, including:
  292. - Gluing together the previous low-level PPP code in lwIP to pppd 2.4.5, which
  293. is more or less what pppd sys-* files are, so that we get something working
  294. using the unix port.
  295. - Merged some patchs from lwIP Git repository which add interesting features
  296. or fix bugs.
  297. - Merged some patchs from Debian pppd package which add interesting features
  298. or fix bugs.
  299. - Ported PPP timeout handling to the lwIP timers system
  300. - Disabled all the PPP code using filesystem access, replaced in necessary cases
  301. to configuration variables.
  302. - Disabled all the PPP code forking processes.
  303. - Removed IPX support, lwIP does not support IPX.
  304. - Ported and improved random module from the previous PPP port.
  305. - Removed samba TDB (file-driven database) usage, because it needs a filesystem.
  306. - MS-CHAP required a DES implementation, we added the latest PolarSSL DES
  307. implementation which is under a BSD-ish license.
  308. - Also switched to PolarSSL MD4,MD5,SHA1 implementations, which are meant to be
  309. used in embedded devices with reduced memory footprint.
  310. - Removed PPP configuration file parsing support.
  311. - Added macro definition EAP_SUPPORT to make EAP support optional.
  312. - Added macro definition CHAP_SUPPORT to make CHAP support optional.
  313. - Added macro definition MSCHAP_SUPPORT to make MSCHAP support optional.
  314. - Added macro definition PAP_SUPPORT to make PAP support optional.
  315. - Cleared all Linux syscall calls.
  316. - Disabled demand support using a macro, so that it can be ported later.
  317. - Disabled ECP support using a macro, so that it can be ported later.
  318. - Disabled CCP support using a macro, so that it can be ported later.
  319. - Disabled CBCP support using a macro, so that it can be ported later.
  320. - Disabled LQR support using a macro, so that it can be ported later.
  321. - Print packet debug feature optional, through PRINTPKT_SUPPORT
  322. - Removed POSIX signal usage.
  323. - Fully ported PPPoS code from the previous port.
  324. - Fully ported PPPoE code from the previous port.
  325. - Fully ported VJ compression protocol code from the previous port.
  326. - Removed all malloc()/free() use from PPP, replaced by stack usage or PBUF.
  327. - Disabled PPP server support using a macro, so that it can be ported later.
  328. - Switched all PPP debug to lwIP debug system.
  329. - Created PPP Control Block (PPP PCB), removed PPP unit integer everywhere,
  330. removed all global variables everywhere, did everything necessary for
  331. the PPP stack to support more than one PPP session (pppd only support
  332. one session per process).
  333. - Removed the statically allocated output buffer, now using PBUF.
  334. - Improved structure size of all PPP modules, deep analyze of code to reduce
  335. variables size to the bare minimum. Switched all boolean type (char type in
  336. most architecture) to compiler generated bitfields.
  337. - Added PPP IPv6 support, glued lwIP IPv6 support to PPP.
  338. - Now using a persistent netif interface which can then be used in lwIP
  339. functions requiring a netif.
  340. - Now initializing PPP in lwip_init() function.
  341. - Reworked completely the PPP state machine, so that we don't end up in
  342. anymore in inconsistent state, especially with PPPoE.
  343. - Improved the way we handle PPP reconnection after disconnect, cleaning
  344. everything required so that we start the PPP connection again from a
  345. clean state.
  346. - Added PPP holdoff support, allow the lwIP user to wait a little bit before
  347. reconnecting, prevents connection flood, especially when using PPPoL2TP.
  348. - Added PPPoL2TP LAC support (a.k.a. UDP tunnels), adding a VPN client
  349. feature to lwIP, L2TP being a widely used tunnel protocol.
  350. - Switched all used PPP types to lwIP types (u8t, u16t, u32t, ...)
  351. - Added PPP API "sequential" thread-safe API, based from NETIFAPI.
  352. 2011-07-21: Simon Goldschmidt
  353. * sockets.c, opt.h: (bug #30185): added LWIP_FIONREAD_LINUXMODE that makes
  354. ioctl/FIONREAD return the size of the next pending datagram.
  355. 2011-05-25: Simon Goldschmidt
  356. * again nearly the whole stack, renamed ip.c to ip4.c, ip_addr.c to ip4_addr.c,
  357. combined ipv4/ipv6 inet_chksum.c, added ip.h, ip_addr.h: Combined IPv4
  358. and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP
  359. code so that the code is more readable.
  360. 2011-05-17: Patch by Ivan Delamer (only checked in by Simon Goldschmidt)
  361. * nearly the whole stack: Finally, we got decent IPv6 support, big thanks to
  362. Ivan! (this is work in progress: we're just post release anyway :-)
  363. ++ Bugfixes:
  364. 2016-08-23: Simon Goldschmidt
  365. * etharp: removed ETHARP_TRUST_IP_MAC since it is insecure and we don't need
  366. it any more after implementing unicast ARP renewal towards arp entry timeout
  367. 2016-07-20: Simon Goldschmidt
  368. * memp.h/.c: fixed bug #48442 (memp stats don't work for MEMP_MEM_MALLOC)
  369. 2016-07-21: Simon Goldschmidt (patch by Ambroz Bizjak)
  370. * tcp_in.c, tcp_out.c: fixed bug #48543 (TCP sent callback may prematurely
  371. report sent data when only part of a segment is acked) and don't include
  372. SYN/FIN in snd_buf counter
  373. 2016-07-19: Simon Goldschmidt
  374. * etharp.c: fixed bug #48477 (ARP input packet might update static entry)
  375. 2016-07-11: Simon Goldschmidt
  376. * tcp_in.c: fixed bug #48476 (TCP sent callback called wrongly due to picking
  377. up old pcb->acked
  378. 2016-06-30: Simon Goldschmidt (original patch by Fabian Koch)
  379. * tcp_in.c: fixed bug #48170 (Vulnerable to TCP RST spoofing)
  380. 2016-05-20: Dirk Ziegelmeier
  381. * sntp.h/.c: Fix return value of sntp_getserver() call to return a pointer
  382. 2016-04-05: Simon Goldschmidt (patch by Philip Gladstone)
  383. * udp.c: patch #8358: allow more combinations of listening PCB for IPv6
  384. 2016-04-05: Simon Goldschmidt
  385. * netconn/socket API: fixed bug# 43739 (Accept not reporting errors about
  386. aborted connections): netconn_accept() returns ERR_ABRT (sockets: ECONNABORTED)
  387. for aborted connections, ERR_CLSD (sockets: EINVAL) if the listening netconn
  388. is closed, which better seems to follow the standard.
  389. 2016-03-23: Florent Matignon
  390. * dhcp.c: fixed bug #38203: DHCP options are not recorded in all DHCP ack messages
  391. 2016-03-22: Simon Goldschmidt
  392. * tcp: changed accept handling to be done internally: the application does not
  393. have to call tcp_accepted() any more. Instead, when delaying accept (e.g. sockets
  394. do), call tcp_backlog_delayed()/tcp_backlog_accepted() (fixes bug #46696)
  395. 2016-03-22: Simon Goldschmidt
  396. * dns.c: ignore dns response parsing errors, only abort resolving for correct
  397. responses or error responses from correct server (bug #47459)
  398. 2016-03-17: Simon Goldschmidt
  399. * api_msg.c: fixed bug #47448 (netconn/socket leak if RST is received during close)
  400. 2016-03-17: Joel Cunningham
  401. * api_msg.c: don't fail closing a socket/netconn when failing to allocate the
  402. FIN segment; blocking the calling thread for a while is better than risking
  403. leaking a netconn/socket (see bug #46701)
  404. 2016-03-16: Joel Cunningham
  405. * tcp_out.c: reset rto timer on fast retransmission
  406. 2016-03-16: Deomid Ryabkov
  407. * tcp_out.c: fixed bug #46384 Segment size calculation bug with MSS != TCP_MSS
  408. 2016-03-05: Simon Goldschmidt
  409. * err.h/.c, sockets.c: ERR_IF is not necessarily a fatal error
  410. 2015-11-19: fix by Kerem Hadimli
  411. * sockets.c: fixed bug #46471: lwip_accept() leaks socket descriptors if new
  412. netconn was already closed because of peer behavior
  413. 2015-11-12: fix by Valery Ushakov
  414. * tcp_in.c: fixed bug #46365 tcp_accept_null() should call tcp_abort()
  415. 2015-10-02: Dirk Ziegelmeier/Simon Goldschmidt
  416. * snmp: cleaned up snmp structs API (fixed race conditions from bug #46089,
  417. reduce ram/rom usage of tables): incompatible change for private MIBs
  418. 2015-09-30: Simon Goldschmidt
  419. * ip4_addr.c: fixed bug #46072: ip4addr_aton() does not check the number range
  420. of all address parts
  421. 2015-08-28: Simon Goldschmidt
  422. * tcp.c, tcp_in.c: fixed bug #44023: TCP ssthresh value is unclear: ssthresh

  703. * posix/*: added posix-compatibility include files posix/netdb.h and posix/sys/socket.h

  724. * opt.h, tcp_impl.h, tcp.c, udp.h/.c: Added a config option to randomize

  925. 2010-06-16: Simon Goldschmidt
  926. * ip.c: Added an optional define (LWIP_IP_ACCEPT_UDP_PORT) that can allow
  927. link-layer-addressed UDP traffic to be received while a netif is down (just
  928. like DHCP during configuration)
  929. 2010-05-22: Simon Goldschmidt
  930. * many many files: bug #27352: removed packing from ip_addr_t, the packed
  931. version is now only used in protocol headers. Added global storage for
  932. current src/dest IP address while in input functions.
  933. 2010-05-16: Simon Goldschmidt
  934. * def.h: task #10391: Add preprocessor-macros for compile-time htonl
  935. calculation (and use them throughout the stack where applicable)
  936. 2010-05-16: Simon Goldschmidt
  937. * opt.h, memp_std.h, memp.c, ppp_oe.h/.c: PPPoE now uses its own MEMP pool
  938. instead of the heap (moved struct pppoe_softc from ppp_oe.c to ppp_oe.h)
  939. 2010-05-16: Simon Goldschmidt
  940. * opt.h, memp_std.h, dns.h/.c: DNS_LOCAL_HOSTLIST_IS_DYNAMIC uses its own

  951. take a precalculated checksum, added pbuf_fill_chksum() to copy data
  952. into a pbuf and at the same time calculating the checksum for that data
  953. 2010-04-29: Simon Goldschmidt
  954. * ip_addr.h, etharp.h/.c, autoip.c: Create overridable macros for copying

  962. * ip_frag.c: create a new (contiguous) PBUF_RAM for every outgoing
  963. fragment if LWIP_NETIF_TX_SINGLE_PBUF==1
  964. 2010-03-27: Simon Goldschmidt
  965. * etharp.c: Speedup TX by moving code from find_entry to etharp_output/
  966. etharp_query to prevent unnecessary function calls (inspired by
  967. patch #7135).
  968. 2010-03-20: Simon Goldschmidt
  969. * opt.h, tcpip.c/.h: Added an option to disable tcpip_(un)timeout code
  970. since the linker cannot do this automatically to save space.
  971. 2010-03-20: Simon Goldschmidt
  972. * opt.h, etharp.c/.h: Added support for static ARP table entries
  973. 2010-03-14: Simon Goldschmidt

  975. when creating TCP segments, not when (re-)transmitting them.
  976. 2010-03-07: Simon Goldschmidt
  977. * sockets.c: bug #28775 (select/event_callback: only check select_cb_list
  978. on change) plus use SYS_LIGHTWEIGHT_PROT to protect the select code.
  979. This should speed up receiving data on sockets as the select code in
  980. event_callback is only executed when select is waiting.
  981. 2010-03-06: Simon Goldschmidt
  982. * tcp_out.c: task #7013 (Create option to have all packets delivered to
  983. netif->output in one piece): Always copy to try to create single pbufs
  984. in tcp_write.
  985. 2010-03-06: Simon Goldschmidt
  986. * api.h, api_lib.c, sockets.c: task #10167 (sockets: speed up TCP recv
  987. by not allocating a netbuf): added function netconn_recv_tcp_pbuf()
  988. for tcp netconns to receive pbufs, not netbufs; use that function
  989. for tcp sockets.
  990. 2010-03-05: Jakob Ole Stoklundsen / Simon Goldschmidt
  991. * opt.h, tcp.h, tcp_impl.h, tcp.c, tcp_in.c, tcp_out.c: task #7040:
  992. Work on tcp_enqueue: Don't waste memory when chaining segments,
  993. added option TCP_OVERSIZE to prevent creating many small pbufs when
  994. calling tcp_write with many small blocks of data. Instead, pbufs are
  995. allocated larger than needed and the space is used for later calls to
  996. tcp_write.
  997. 2010-02-21: Simon Goldschmidt
  998. * stats.c/.h: Added const char* name to mem- and memp-stats for easier
  999. debugging.
  1000. 2010-02-21: Simon Goldschmidt
  1001. * tcp.h (and usages), added tcp_impl.h: Splitted API and internal
  1002. implementation of tcp to make API usage cleare to application programmers
  1003. 2010-02-14: Simon Goldschmidt/Stephane Lesage
  1004. * ip_addr.h: Improved some defines working on ip addresses, added faster
  1005. macro to copy addresses that cannot be NULL
  1006. 2010-02-13: Simon Goldschmidt
  1007. * api.h, api_lib.c, api_msg.c, sockets.c: task #7865 (implement non-
  1008. blocking send operation)
  1009. 2010-02-12: Simon Goldschmidt
  1010. * sockets.c/.h: Added a minimal version of posix fctl() to have a
  1011. standardised way to set O_NONBLOCK for nonblocking sockets.
  1012. 2010-02-12: Simon Goldschmidt
  1013. * dhcp.c/.h, autoip.c/.h: task #10139 (Prefer statically allocated
  1014. memory): added autoip_set_struct() and dhcp_set_struct() to let autoip
  1015. and dhcp work with user-allocated structs instead of callin mem_malloc
  1016. 2010-02-12: Simon Goldschmidt/Jeff Barber
  1017. * tcp.c/h: patch #6865 (SO_REUSEADDR for TCP): if pcb.so_options has
  1018. SOF_REUSEADDR set, allow binding to endpoint in TIME_WAIT
  1019. 2010-02-12: Simon Goldschmidt
  1020. * sys layer: task #10139 (Prefer statically allocated memory): converted
  1021. mbox and semaphore functions to take pointers to sys_mbox_t/sys_sem_t;
  1022. converted sys_mbox_new/sys_sem_new to take pointers and return err_t;
  1023. task #7212: Add Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX
  1024. to let sys.h use binary semaphores instead of mutexes - as before)
  1025. 2010-02-09: Simon Goldschmidt (Simon Kallweit)
  1026. * timers.c/.h: Added function sys_restart_timeouts() from patch #7085
  1027. (Restart system timeout handling)
  1028. 2010-02-09: Simon Goldschmidt
  1029. * netif.c/.h, removed loopif.c/.h: task #10153 (Integrate loopif into
  1030. netif.c) - loopif does not have to be created by the port any more,
  1031. just define LWIP_HAVE_LOOPIF to 1.
  1032. 2010-02-08: Simon Goldschmidt
  1033. * inet.h, ip_addr.c/.h: Added reentrant versions of inet_ntoa/ipaddr_ntoa
  1034. inet_ntoa_r/ipaddr_ntoa_r
  1035. 2010-02-08: Simon Goldschmidt
  1036. * netif.h: Added netif_s/get_igmp_mac_filter() macros
  1037. 2010-02-05: Simon Goldschmidt

  1040. * nearly every file: Replaced struct ip_addr by typedef ip_addr_t to
  1041. make changing the actual implementation behind the typedef easier.
  1042. 2010-02-01: Simon Goldschmidt
  1043. * opt.h, memp_std.h, dns.h, netdb.c, memp.c: Let netdb use a memp pool
  1044. for allocating memory when getaddrinfo() is called.
  1045. 2010-01-31: Simon Goldschmidt
  1046. * dhcp.h, dhcp.c: Reworked the code that parses DHCP options: parse
  1047. them once instead of parsing for every option. This also removes
  1048. the need for mem_malloc from dhcp_recv and makes it possible to
  1049. correctly retrieve the BOOTP file.
  1050. 2010-01-30: simon Goldschmidt
  1051. * sockets.c: Use SYS_LIGHTWEIGHT_PROT instead of a semaphore to protect
  1052. the sockets array.

  1059. plus many cleanups in socket & netconn API.
  1060. 2010-01-27: Simon Goldschmidt
  1061. * opt.h, tcp.h, init.c, api_msg.c: Added TCP_SNDQUEUELOWAT corresponding
  1062. to TCP_SNDLOWAT and added tcp_sndqueuelen() - this fixes bug #28605
  1063. 2010-01-26: Simon Goldschmidt
  1064. * snmp: Use memp pools for snmp instead of the heap; added 4 new pools.
  1065. 2010-01-14: Simon Goldschmidt
  1066. * ppp.c/.h: Fixed bug #27856: PPP: Set netif link- and status-callback

  1068. 2010-01-13: Simon Goldschmidt
  1069. * mem.c: The heap now may be moved to user-defined memory by defining

  1071. (patch #6966 and bug #26133)
  1072. 2010-01-10: Simon Goldschmidt (Bill Auerbach)
  1073. * opt.h, memp.c: patch #6822 (Add option to place memory pools in

  1077. LWIP_RAND() for lwip-wide randomization (to be defined in cc.h)
  1078. 2009-12-31: Simon Goldschmidt
  1079. * tcpip.c, init.c, memp.c, sys.c, memp_std.h, sys.h, tcpip.h
  1080. added timers.c/.h: Separated timer implementation from semaphore/mbox
  1081. implementation, moved timer implementation to timers.c/.h, timers are
  1082. now only called from tcpip_thread or by explicitly checking them.
  1083. (TASK#7235)
  1084. 2009-12-27: Simon Goldschmidt
  1085. * opt.h, etharp.h/.c, init.c, tcpip.c: Added an additional option
  1086. LWIP_ETHERNET to support ethernet without ARP (necessary for pure PPPoE)
  1087. ++ Bugfixes:
  1088. 2011-04-20: Simon Goldschmidt

  1094. * etharp.h/.c: Fixed broken VLAN support.
  1095. 2011-03-27: Simon Goldschmidt
  1096. * tcp.c: Fixed bug #32926 (TCP_RMV(&tcp_bound_pcbs) is called on unbound tcp
  1097. pcbs) by checking if the pcb was bound (local_port != 0).
  1098. 2011-03-27: Simon Goldschmidt
  1099. * ppp.c: Fixed bug #32280 (ppp: a pbuf is freed twice)
  1100. 2011-03-27: Simon Goldschmidt

  1109. calling sio_read_abort() if the file descriptor is valid.
  1110. 2011-03-14: Simon Goldschmidt
  1111. * err.h/.c, sockets.c, api_msg.c: fixed bug #31748 (Calling non-blocking connect
  1112. more than once can render a socket useless) since it mainly involves changing
  1113. "FATAL" classification of error codes: ERR_USE and ERR_ISCONN just aren't fatal.
  1114. 2011-03-13: Simon Goldschmidt
  1115. * sockets.c: fixed bug #32769 (ESHUTDOWN is linux-specific) by fixing
  1116. err_to_errno_table (ERR_CLSD: ENOTCONN instead of ESHUTDOWN), ERR_ISCONN:
  1117. use EALRADY instead of -1
  1118. 2011-03-13: Simon Goldschmidt
  1119. * api_lib.c: netconn_accept: return ERR_ABRT instead of ERR_CLSD if the
  1120. connection has been aborted by err_tcp (since this is not a normal closing
  1121. procedure).
  1122. 2011-03-13: Simon Goldschmidt
  1123. * tcp.c: tcp_bind: return ERR_VAL instead of ERR_ISCONN when trying to bind

  1137. 2010-11-23: Simon Goldschmidt
  1138. * etharp.c: Fixed bug #31720: ARP-queueing: RFC 1122 recommends to queue at

  1146. 2010-11-22: Simon Goldschmidt
  1147. * etharp.c: Fixed bug #31722: IP packets sent with an AutoIP source addr
  1148. must be sent link-local

  1155. * sockets.h: Fixed bug #31304: Changed SHUT_RD, SHUT_WR and SHUT_RDWR to
  1156. resemble other stacks.
  1157. 2010-11-20: Simon Goldschmidt
  1158. * dns.c: Fixed bug #31535: TCP_SND_QUEUELEN must be at least 2 or else
  1159. no-copy TCP writes will never succeed.
  1160. 2010-11-20: Simon Goldschmidt
  1161. * dns.c: Fixed bug #31701: Error return value from dns_gethostbyname() does

  1245. 2010-03-08: Simon Goldschmidt
  1246. * netif.c, ipv4/ip.c: task #10241 (AutoIP: don't break existing connections

  1270. 2010-02-19: Simon Goldschmidt
  1271. * mem.c/.h, pbuf.c: Renamed mem_realloc() to mem_trim() to prevent
  1272. confusion with realloc()
  1273. 2010-02-15: Simon Goldschmidt/Stephane Lesage
  1274. * netif.c/.h: Link status does not depend on LWIP_NETIF_LINK_CALLBACK

  1276. 2010-02-14: Simon Goldschmidt
  1277. * netif.c: Fixed bug #28877 (Duplicate ARP gratuitous packet with

  1279. admin-status of a netif are up
  1280. 2010-02-14: Simon Goldschmidt
  1281. * opt.h: Disable ETHARP_TRUST_IP_MAC by default since it slows down packet
  1282. reception and is not really necessary
  1283. 2010-02-14: Simon Goldschmidt
  1284. * etharp.c/.h: Fixed ARP input processing: only add a new entry if a
  1285. request was directed as us (RFC 826, Packet Reception), otherwise
  1286. only update existing entries; internalized some functions
  1287. 2010-02-14: Simon Goldschmidt
  1288. * netif.h, etharp.c, tcpip.c: Fixed bug #28183 (ARP and TCP/IP cannot be
  1289. disabled on netif used for PPPoE) by adding a new netif flag
  1290. (NETIF_FLAG_ETHERNET) that tells the stack the device is an ethernet
  1291. device but prevents usage of ARP (so that ethernet_input can be used
  1292. for PPPoE).
  1293. 2010-02-12: Simon Goldschmidt
  1294. * netif.c: netif_set_link_up/down: only do something if the link state
  1295. actually changes
  1296. 2010-02-12: Simon Goldschmidt/Stephane Lesage
  1297. * api_msg.c: Fixed bug #28865 (Cannot close socket/netconn in non-blocking

  1302. * api_lib.c, api_msg.c, sockets.c, api.h, api_msg.h: Fixed bug #22110
  1303. (recv() makes receive window update for data that wasn't received by
  1304. application)
  1305. 2010-02-09: Simon Goldschmidt/Stephane Lesage
  1306. * sockets.c: Fixed bug #28853 (lwip_recvfrom() returns 0 on receive time-out
  1307. or any netconn_recv() error)
  1308. 2010-02-09: Simon Goldschmidt
  1309. * ppp.c: task #10154 (PPP: Update snmp in/out counters for tx/rx packets)
  1310. 2010-02-09: Simon Goldschmidt

  1312. for the loopback netif.
  1313. 2010-02-08: Simon Goldschmidt
  1314. * igmp.c/.h, ip.h: Moved most defines from igmp.h to igmp.c for clarity
  1315. since they are not used anywhere else.
  1316. 2010-02-08: Simon Goldschmidt (Stéphane Lesage)
  1317. * igmp.c, igmp.h, stats.c, stats.h: Improved IGMP stats

  1319. 2010-02-08: Simon Goldschmidt (Stéphane Lesage)
  1320. * igmp.c: Fixed bug #28798 (Error in "Max Response Time" processing) and
  1321. another bug when LWIP_RAND() returns zero.
  1322. 2010-02-04: Simon Goldschmidt
  1323. * nearly every file: Use macros defined in ip_addr.h (some of them new)
  1324. to work with IP addresses (preparation for bug #27352 - Change ip_addr
  1325. from struct to typedef (u32_t) - and better code).
  1326. 2010-01-31: Simon Goldschmidt
  1327. * netif.c: Don't call the link-callback from netif_set_up/down() since
  1328. this invalidly retriggers DHCP.
  1329. 2010-01-29: Simon Goldschmidt
  1330. * ip_addr.h, inet.h, def.h, inet.c, def.c, more: Cleanly separate the
  1331. portability file inet.h and its contents from the stack: moved htonX-
  1332. functions to def.h (and the new def.c - they are not ipv4 dependent),
  1333. let inet.h depend on ip_addr.h and not the other way round.
  1334. This fixes bug #28732.
  1335. 2010-01-28: Kieran Mansley
  1336. * tcp.c: Ensure ssthresh >= 2*MSS
  1337. 2010-01-27: Simon Goldschmidt
  1338. * tcp.h, tcp.c, tcp_in.c: Fixed bug #27871: Calling tcp_abort() in recv
  1339. callback can lead to accessing unallocated memory. As a consequence,
  1340. ERR_ABRT means the application has called tcp_abort()!
  1341. 2010-01-25: Simon Goldschmidt
  1342. * snmp_structs.h, msg_in.c: Partly fixed bug #22070 (MIB_OBJECT_WRITE_ONLY
  1343. not implemented in SNMP): write-only or not-accessible are still
  1344. returned by getnext (though not by get)
  1345. 2010-01-24: Simon Goldschmidt
  1346. * snmp: Renamed the private mib node from 'private' to 'mib_private' to
  1347. not use reserved C/C++ keywords
  1348. 2010-01-23: Simon Goldschmidt
  1349. * sockets.c: Fixed bug #28716: select() returns 0 after waiting for less

  1709. 2009-02-18 Simon Goldschmidt (Jonathan Larmour and Bill Auerbach)
  1710. * ip_frag.c: patch #6528: the buffer used for IP_FRAG_USES_STATIC_BUF could be
  1711. too small depending on MEM_ALIGNMENT
  1712. 2009-02-16 Simon Goldschmidt
  1713. * sockets.h/.c, api_*.h/.c: fixed arguments of socket functions to match the standard;

  1729. in state SYN_RCVD is close.
  1730. 2009-01-28 Jonathan Larmour
  1731. * pbuf.c: reclaim pbufs from TCP out-of-sequence segments if we run
  1732. out of pool pbufs.
  1733. 2008-12-19 Simon Goldschmidt
  1734. * many files: patch #6699: fixed some warnings on platform where sizeof(int) == 2

  1748. padding is included.
  1749. 2008-09-30 Jonathan Larmour
  1750. * sockets.c (lwip_accept): check addr isn't NULL. If it's valid, do an
  1751. assertion check that addrlen isn't NULL.
  1752. 2008-09-30 Jonathan Larmour
  1753. * tcp.c: Fix bug #24227, wrong error message in tcp_bind.
  1754. 2008-08-26 Simon Goldschmidt

  1760. 2008-07-08 Frédéric Bernon
  1761. * stats.h: Fix some build bugs introduced with patch #6483 (missing some parameters
  1762. in macros, mainly if MEM_STATS=0 and MEMP_STATS=0).
  1763. 2008-06-24 Jonathan Larmour
  1764. * tcp_in.c: Fix for bug #23693 as suggested by Art R. Ensure cseg is unused
  1765. if tcp_seg_copy fails.
  1766. 2008-06-17 Simon Goldschmidt
  1767. * inet_chksum.c: Checked in some ideas of patch #6460 (loop optimizations)
  1768. and created defines for swapping bytes and folding u32 to u16.
  1769. 2008-05-30 Kieran Mansley
  1770. * tcp_in.c Remove redundant "if" statement, and use real rcv_wnd
  1771. rather than rcv_ann_wnd when deciding if packets are in-window.
  1772. Contributed by <arasmussen@consultant.datasys.swri.edu>
  1773. 2008-05-30 Kieran Mansley
  1774. * mem.h: Fix BUG#23254. Change macro definition of mem_* to allow
  1775. passing as function pointers when MEM_LIBC_MALLOC is defined.
  1776. 2008-05-09 Jonathan Larmour
  1777. * err.h, err.c, sockets.c: Fix bug #23119: Reorder timeout error code to
  1778. stop it being treated as a fatal error.
  1779. 2008-04-15 Simon Goldschmidt
  1780. * dhcp.c: fixed bug #22804: dhcp_stop doesn't clear NETIF_FLAG_DHCP
  1781. (flag now cleared)
  1782. 2008-03-27 Simon Goldschmidt
  1783. * mem.c, tcpip.c, tcpip.h, opt.h: fixed bug #21433 (Calling mem_free/pbuf_free
  1784. from interrupt context isn't safe): set LWIP_USE_HEAP_FROM_INTERRUPT to 1
  1785. in lwipopts.h or use pbuf_free_callback(p)/mem_free_callback(m) to free pbufs
  1786. or heap memory from interrupt context
  1787. 2008-03-26 Simon Goldschmidt
  1788. * tcp_in.c, tcp.c: fixed bug #22249: division by zero could occur if a remote
  1789. host sent a zero mss as TCP option.
  1790. (STABLE-1.3.0)
  1791. ++ New features:
  1792. 2008-03-10 Jonathan Larmour
  1793. * inet_chksum.c: Allow choice of one of the sample algorithms to be
  1794. made from lwipopts.h. Fix comment on how to override LWIP_CHKSUM.
  1795. 2008-01-22 Frédéric Bernon
  1796. * tcp.c, tcp_in.c, tcp.h, opt.h: Rename LWIP_CALCULATE_EFF_SEND_MSS in
  1797. TCP_CALCULATE_EFF_SEND_MSS to have coherent TCP options names.
  1798. 2008-01-14 Frédéric Bernon
  1799. * rawapi.txt, api_msg.c, tcp.c, tcp_in.c, tcp.h: changes for task #7675 "Enable
  1800. to refuse data on a TCP_EVENT_RECV call". Important, behavior changes for the
  1801. tcp_recv callback (see rawapi.txt).
  1802. 2008-01-14 Frédéric Bernon, Marc Chaland
  1803. * ip.c: Integrate patch #6369" ip_input : checking before realloc".
  1804. 2008-01-12 Frédéric Bernon
  1805. * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
  1806. netconn::sem per netconn::op_completed like suggested for the task #7490
  1807. "Add return value to sys_mbox_post".
  1808. 2008-01-12 Frédéric Bernon
  1809. * api_msg.c, opt.h: replace DEFAULT_RECVMBOX_SIZE per DEFAULT_TCP_RECVMBOX_SIZE,
  1810. DEFAULT_UDP_RECVMBOX_SIZE and DEFAULT_RAW_RECVMBOX_SIZE (to optimize queues
  1811. sizes), like suggested for the task #7490 "Add return value to sys_mbox_post".
  1812. 2008-01-10 Frédéric Bernon
  1813. * tcpip.h, tcpip.c: add tcpip_callback_with_block function for the task #7490
  1814. "Add return value to sys_mbox_post". tcpip_callback is always defined as
  1815. "blocking" ("block" parameter = 1).
  1816. 2008-01-10 Frédéric Bernon
  1817. * tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the field
  1818. netconn::mbox (sys_mbox_t) per netconn::sem (sys_sem_t) for the task #7490
  1819. "Add return value to sys_mbox_post".
  1820. 2008-01-05 Frédéric Bernon
  1821. * sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h, opt.h:
  1822. Introduce changes for task #7490 "Add return value to sys_mbox_post" with some
  1823. modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which
  1824. indicate the number of pointers query by the mailbox. There is three defines
  1825. in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the
  1826. netconn::acceptmbox. Port maintainers, you can decide to just add this new
  1827. parameter in your implementation, but to ignore it to keep the previous behavior.
  1828. The new sys_mbox_trypost function return a value to know if the mailbox is
  1829. full or if the message is posted. Take a look to sys_arch.txt for more details.
  1830. This new function is used in tcpip_input (so, can be called in an interrupt
  1831. context since the function is not blocking), and in recv_udp and recv_raw.
  1832. 2008-01-04 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
  1833. * rawapi.txt, api.h, api_lib.c, api_msg.h, api_msg.c, sockets.c, tcp.h, tcp.c,
  1834. tcp_in.c, init.c, opt.h: rename backlog options with TCP_ prefix, limit the
  1835. "backlog" parameter in an u8_t, 0 is interpreted as "smallest queue", add
  1836. documentation in the rawapi.txt file.
  1837. 2007-12-31 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
  1838. * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Add TCP persist timer
  1839. 2007-12-31 Frédéric Bernon, Luca Ceresoli
  1840. * autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP packets
  1841. in autoip". The change in etharp_raw could be removed, since all calls to
  1842. etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be
  1843. wrong in the future.
  1844. 2007-12-30 Frédéric Bernon, Tom Evans
  1845. * ip.c: Fix bug #21846 "LwIP doesn't appear to perform any IP Source Address
  1846. Filtering" reported by Tom Evans.
  1847. 2007-12-21 Frédéric Bernon, Simon Goldschmidt, Jonathan Larmour
  1848. * tcp.h, opt.h, api.h, api_msg.h, tcp.c, tcp_in.c, api_lib.c, api_msg.c,
  1849. sockets.c, init.c: task #7252: Implement TCP listen backlog: Warning: raw API
  1850. applications have to call 'tcp_accepted(pcb)' in their accept callback to
  1851. keep accepting new connections.
  1852. 2007-12-13 Frédéric Bernon
  1853. * api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum dns_result"
  1854. by err_t type. Add a new err_t code "ERR_INPROGRESS".
  1855. 2007-12-12 Frédéric Bernon
  1856. * dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles
  1857. are the one which have ram usage.
  1858. 2007-12-05 Frédéric Bernon
  1859. * netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static
  1860. set of variables (=0) or a local one (=1). In this last case, your port should
  1861. provide a function "struct hostent* sys_thread_hostent( struct hostent* h)"
  1862. which have to do a copy of "h" and return a pointer ont the "per-thread" copy.
  1863. 2007-12-03 Simon Goldschmidt
  1864. * ip.c: ip_input: check if a packet is for inp first before checking all other
  1865. netifs on netif_list (speeds up packet receiving in most cases)
  1866. 2007-11-30 Simon Goldschmidt
  1867. * udp.c, raw.c: task #7497: Sort lists (pcb, netif, ...) for faster access
  1868. UDP: move a (connected) pcb selected for input to the front of the list of
  1869. pcbs so that it is found faster next time. Same for RAW pcbs that have eaten
  1870. a packet.
  1871. 2007-11-28 Simon Goldschmidt
  1872. * etharp.c, stats.c, stats.h, opt.h: Introduced ETHARP_STATS
  1873. 2007-11-25 Simon Goldschmidt
  1874. * dhcp.c: dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy
  1875. algorithm.
  1876. 2007-11-24 Simon Goldschmidt
  1877. * netdb.h, netdb.c, sockets.h/.c: Moved lwip_gethostbyname from sockets.c
  1878. to the new file netdb.c; included lwip_getaddrinfo.
  1879. 2007-11-21 Simon Goldschmidt
  1880. * tcp.h, opt.h, tcp.c, tcp_in.c: implemented calculating the effective send-mss
  1881. based on the MTU of the netif used to send. Enabled by default. Disable by
  1882. setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21492.
  1883. 2007-11-19 Frédéric Bernon
  1884. * api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name
  1885. received match the name query), implement DNS_USES_STATIC_BUF (the place where
  1886. copy dns payload to parse the response), return an error if there is no place
  1887. for a new query, and fix some minor problems.
  1888. 2007-11-16 Simon Goldschmidt
  1889. * new files: ipv4/inet.c, ipv4/inet_chksum.c, ipv6/inet6.c
  1890. removed files: core/inet.c, core/inet6.c
  1891. Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into
  1892. inet and chksum part; changed includes in all lwIP files as appropriate
  1893. 2007-11-16 Simon Goldschmidt
  1894. * api.h, api_msg.h, api_lib.c, api_msg.c, socket.h, socket.c: Added sequential
  1895. dns resolver function for netconn api (netconn_gethostbyname) and socket api
  1896. (gethostbyname/gethostbyname_r).
  1897. 2007-11-15 Jim Pettinato, Frédéric Bernon
  1898. * opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name
  1899. requests with RAW api interface. Initialization is done in lwip_init() with
  1900. build time options. DNS timer is added in tcpip_thread context. DHCP can set
  1901. DNS server ip addresses when options are received. You need to set LWIP_DNS=1
  1902. in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get
  1903. some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo"
  1904. list with points to improve.
  1905. 2007-11-06 Simon Goldschmidt
  1906. * opt.h, mib2.c: Patch #6215: added ifAdminStatus write support (if explicitly
  1907. enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status
  1908. for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.
  1909. 2007-11-06 Simon Goldschmidt
  1910. * api.h, api_msg.h and dependent files: Task #7410: Removed the need to include
  1911. core header files in api.h (ip/tcp/udp/raw.h) to hide the internal
  1912. implementation from netconn api applications.
  1913. 2007-11-03 Frédéric Bernon
  1914. * api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP &
  1915. RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled
  1916. by default). Netconn API users can use the netconn_recv_bufsize macro to access
  1917. it. This is a first release which have to be improve for TCP. Note it used the
  1918. netconn::recv_avail which need to be more "thread-safe" (note there is already
  1919. the problem for FIONREAD with lwip_ioctl/ioctlsocket).
  1920. 2007-11-01 Frédéric Bernon, Marc Chaland
  1921. * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c:
  1922. Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api
  1923. layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api
  1924. layer. This option enable to delayed TCP PUSH flag on multiple "write" calls.
  1925. Note that previous "copy" parameter for "write" APIs is now called "apiflags".
  1926. 2007-10-24 Frédéric Bernon
  1927. * api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than
  1928. TCP_EVENT_xxx macros to get a code more readable. It could also help to remove
  1929. some code (like we have talk in "patch #5919 : Create compile switch to remove
  1930. select code"), but it could be done later.
  1931. 2007-10-08 Simon Goldschmidt
  1932. * many files: Changed initialization: many init functions are not needed any
  1933. more since we now rely on the compiler initializing global and static
  1934. variables to zero!
  1935. 2007-10-06 Simon Goldschmidt
  1936. * ip_frag.c, memp.c, mib2.c, ip_frag.h, memp_std.h, opt.h: Changed IP_REASSEMBLY
  1937. to enqueue the received pbufs so that multiple packets can be reassembled
  1938. simultaneously and no static reassembly buffer is needed.
  1939. 2007-10-05 Simon Goldschmidt
  1940. * tcpip.c, etharp.h, etharp.c: moved ethernet_input from tcpip.c to etharp.c so
  1941. all netifs (or ports) can use it.
  1942. 2007-10-05 Frédéric Bernon
  1943. * netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the
  1944. common function to reduce a little bit the footprint (for all functions using
  1945. only the "netif" parameter).
  1946. 2007-10-03 Frédéric Bernon
  1947. * netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down,
  1948. netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce
  1949. a little bit the footprint (for all functions using only the "netif" parameter).
  1950. 2007-09-15 Frédéric Bernon
  1951. * udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF
  1952. option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for
  1953. netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for
  1954. IP_MULTICAST_TTL and IP_MULTICAST_IF.
  1955. 2007-09-10 Frédéric Bernon
  1956. * snmp.h, mib2.c: enable to remove SNMP timer (which consumne several cycles
  1957. even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime()
  1958. each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can
  1959. decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but
  1960. call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime()
  1961. or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
  1962. This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
  1963. snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
  1964. when it's queried (any direct call to "sysuptime" is changed by a call to
  1965. snmp_get_sysuptime).
  1966. 2007-09-09 Frédéric Bernon, Bill Florac
  1967. * igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP,
  1968. and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags
  1969. if you want IGMP on an interface. igmp_stop() is now called inside netif_remove().
  1970. igmp_report_groups() is now called inside netif_set_link_up() (need to have
  1971. LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait
  1972. the next query message to receive the matching multicast streams).
  1973. 2007-09-08 Frédéric Bernon
  1974. * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains
  1975. IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change).
  1976. Use this new field to access to common pcb fields (ttl, tos, so_options, etc...).
  1977. Enable to access to these fields with LWIP_TCP=0.
  1978. 2007-09-05 Frédéric Bernon
  1979. * udp.c, ipv4/icmp.c, ipv4/ip.c, ipv6/icmp.c, ipv6/ip6.c, ipv4/icmp.h,
  1980. ipv6/icmp.h, opt.h: Integrate "task #7272 : LWIP_ICMP option". The new option
  1981. LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default).
  1982. Be careful, disabling ICMP make your product non-compliant to RFC1122, but
  1983. help to reduce footprint, and to reduce "visibility" on the Internet.
  1984. 2007-09-05 Frédéric Bernon, Bill Florac
  1985. * opt.h, sys.h, tcpip.c, slipif.c, ppp.c, sys_arch.txt: Change parameters list
  1986. for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new
  1987. parameters have to be provided: a task name, and a task stack size. For this
  1988. one, since it's platform dependant, you could define the best one for you in
  1989. your lwipopts.h. For port maintainers, you can just add these new parameters
  1990. in your sys_arch.c file, and but it's not mandatory, use them in your OS
  1991. specific functions.
  1992. 2007-09-05 Frédéric Bernon
  1993. * inet.c, autoip.c, msg_in.c, msg_out.c, init.c: Move some build time checkings
  1994. inside init.c for task #7142 "Sanity check user-configurable values".
  1995. 2007-09-04 Frédéric Bernon, Bill Florac
  1996. * igmp.h, igmp.c, memp_std.h, memp.c, init.c, opt.h: Replace mem_malloc call by
  1997. memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the
  1998. value). It will avoid potential fragmentation problems, use a counter to know
  1999. how many times a group is used on an netif, and free it when all applications
  2000. leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity
  2001. check if LWIP_IGMP!=0).
  2002. 2007-09-03 Frédéric Bernon
  2003. * igmp.h, igmp.c, sockets.c, api_msg.c: Changes for "#20503 IGMP Improvement".
  2004. Initialize igmp_mac_filter to NULL in netif_add (this field should be set in
  2005. the netif's "init" function). Use the "imr_interface" field (for socket layer)
  2006. and/or the "interface" field (for netconn layer), for join/leave operations.
  2007. The igmp_join/leavegroup first parameter change from a netif to an ipaddr.
  2008. This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany).
  2009. 2007-08-30 Frédéric Bernon
  2010. * Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions
  2011. from api/api_lib". Now netbuf API is independant of netconn, and can be used
  2012. with other API (application based on raw API, or future "socket2" API). Ports
  2013. maintainers just have to add src/api/netbuf.c in their makefile/projects.
  2014. 2007-08-30 Frédéric Bernon, Jonathan Larmour
  2015. * init.c: Add first version of lwip_sanity_check for task #7142 "Sanity check
  2016. user-configurable values".
  2017. 2007-08-29 Frédéric Bernon
  2018. * igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start.
  2019. igmp_start is call inside netif_add. Now, igmp initialization is in the same
  2020. spirit than the others modules. Modify some IGMP debug traces.
  2021. 2007-08-29 Frédéric Bernon
  2022. * Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function"
  2023. Add lwip_init function to regroup all modules initializations, and to provide
  2024. a place to add code for task #7142 "Sanity check user-configurable values".
  2025. Ports maintainers should remove direct initializations calls from their code,
  2026. and add init.c in their makefiles. Note that lwip_init() function is called
  2027. inside tcpip_init, but can also be used by raw api users since all calls are
  2028. disabled when matching options are disabled. Also note that their is new options
  2029. in opt.h, you should configure in your lwipopts.h (they are enabled per default).
  2030. 2007-08-26 Marc Boucher
  2031. * api_msg.c: do_close_internal(): Reset the callbacks and arg (conn) to NULL
  2032. since they can under certain circumstances be called with an invalid conn
  2033. pointer after the connection has been closed (and conn has been freed).
  2034. 2007-08-25 Frédéric Bernon (Artem Migaev's Patch)
  2035. * netif.h, netif.c: Integrate "patch #6163 : Function to check if link layer is up".
  2036. Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set.
  2037. 2007-08-22 Frédéric Bernon
  2038. * netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in LWIP_NETIF_STATUS_CALLBACK
  2039. to be coherent with new LWIP_NETIF_LINK_CALLBACK option before next release.
  2040. 2007-08-22 Frédéric Bernon
  2041. * tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT &
  2042. ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the
  2043. name is tcpip_input (we keep the name of 1.2.0 function).
  2044. 2007-08-17 Jared Grubb
  2045. * memp_std.h, memp.h, memp.c, mem.c, stats.c: (Task #7136) Centralize mempool
  2046. settings into new memp_std.h and optional user file lwippools.h. This adds
  2047. more dynamic mempools, and allows the user to create an arbitrary number of
  2048. mempools for mem_malloc.
  2049. 2007-08-16 Marc Boucher
  2050. * api_msg.c: Initialize newconn->state to NETCONN_NONE in accept_function;
  2051. otherwise it was left to NETCONN_CLOSE and sent_tcp() could prematurely
  2052. close the connection.
  2053. 2007-08-16 Marc Boucher
  2054. * sockets.c: lwip_accept(): check netconn_peer() error return.
  2055. 2007-08-16 Marc Boucher
  2056. * mem.c, mem.h: Added mem_calloc().
  2057. 2007-08-16 Marc Boucher
  2058. * tcpip.c, tcpip.h memp.c, memp.h: Added distinct memp (MEMP_TCPIP_MSG_INPKT)
  2059. for input packets to prevent floods from consuming all of MEMP_TCPIP_MSG
  2060. and starving other message types.
  2061. Renamed MEMP_TCPIP_MSG to MEMP_TCPIP_MSG_API
  2062. 2007-08-16 Marc Boucher
  2063. * pbuf.c, pbuf.h, etharp.c, tcp_in.c, sockets.c: Split pbuf flags in pbuf
  2064. type and flgs (later renamed to flags).
  2065. Use enum pbuf_flag as pbuf_type. Renumber PBUF_FLAG_*.
  2066. Improved lwip_recvfrom(). TCP push now propagated.
  2067. 2007-08-16 Marc Boucher
  2068. * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global
  2069. provided by etharp.
  2070. 2007-08-16 Marc Boucher
  2071. * ppp_oe.c ppp_oe.h, auth.c chap.c fsm.c lcp.c ppp.c ppp.h,
  2072. etharp.c ethernetif.c, etharp.h, opt.h tcpip.h, tcpip.c:
  2073. Added PPPoE support and various PPP improvements.
  2074. 2007-07-25 Simon Goldschmidt
  2075. * api_lib.c, ip_frag.c, pbuf.c, api.h, pbuf.h: Introduced pbuf_copy_partial,
  2076. making netbuf_copy_partial use this function.
  2077. 2007-07-25 Simon Goldschmidt
  2078. * tcp_in.c: Fix bug #20506: Slow start / initial congestion window starts with
  2079. 2 * mss (instead of 1 * mss previously) to comply with some newer RFCs and
  2080. other stacks.
  2081. 2007-07-13 Jared Grubb (integrated by Frédéric Bernon)
  2082. * opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add
  2083. a link callback in the netif struct, and functions to handle it. Be carefull
  2084. for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c)
  2085. if you want to be sure to be compatible with future changes...
  2086. 2007-06-30 Frédéric Bernon
  2087. * sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.
  2088. 2007-06-21 Simon Goldschmidt
  2089. * etharp.h, etharp.c: Combined etharp_request with etharp_raw for both
  2090. LWIP_AUTOIP =0 and =1 to remove redundant code.
  2091. 2007-06-21 Simon Goldschmidt
  2092. * mem.c, memp.c, mem.h, memp.h, opt.h: task #6863: Introduced the option
  2093. MEM_USE_POOLS to use 4 pools with different sized elements instead of a
  2094. heap. This both prevents memory fragmentation and gives a higher speed
  2095. at the cost of more memory consumption. Turned off by default.
  2096. 2007-06-21 Simon Goldschmidt
  2097. * api_lib.c, api_msg.c, api.h, api_msg.h: Converted the length argument of
  2098. netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into
  2099. int to be able to send a bigger buffer than 64K with one time (mainly
  2100. used from lwip_send).
  2101. 2007-06-21 Simon Goldschmidt
  2102. * tcp.h, api_msg.c: Moved the nagle algorithm from netconn_write/do_write
  2103. into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too.
  2104. 2007-06-21 Simon Goldschmidt
  2105. * api.h, api_lib.c, api_msg.c: Fixed bug #20021: Moved sendbuf-processing in
  2106. netconn_write from api_lib.c to api_msg.c to also prevent multiple context-
  2107. changes on low memory or empty send-buffer.
  2108. 2007-06-18 Simon Goldschmidt
  2109. * etharp.c, etharp.h: Changed etharp to use a defined hardware address length
  2110. of 6 to avoid loading netif->hwaddr_len every time (since this file is only
  2111. used for ethernet and struct eth_addr already had a defined length of 6).
  2112. 2007-06-17 Simon Goldschmidt
  2113. * sockets.c, sockets.h: Implemented socket options SO_NO_CHECK for UDP sockets
  2114. to disable UDP checksum generation on transmit.
  2115. 2007-06-13 Frédéric Bernon, Simon Goldschmidt
  2116. * debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid
  2117. pointers or parameters, and let the possibility to redefined it in cc.h. Use
  2118. this macro to check "conn" parameter in api_msg.c functions.
  2119. 2007-06-11 Simon Goldschmidt
  2120. * sockets.c, sockets.h: Added UDP lite support for sockets
  2121. 2007-06-10 Simon Goldschmidt
  2122. * udp.h, opt.h, api_msg.c, ip.c, udp.c: Included switch LWIP_UDPLITE (enabled
  2123. by default) to switch off UDP-Lite support if not needed (reduces udp.c code
  2124. size)
  2125. 2007-06-09 Dominik Spies (integrated by Frédéric Bernon)
  2126. * autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h:
  2127. AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and
  2128. LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt
  2129. (see TODO mark in the source code).
  2130. 2007-06-09 Simon Goldschmidt
  2131. * etharp.h, etharp.c, ethernetif.c: Modified order of parameters for
  2132. etharp_output() to match netif->output so etharp_output() can be used
  2133. directly as netif->output to save one function call.
  2134. 2007-06-08 Simon Goldschmidt
  2135. * netif.h, ethernetif.c, slipif.c, loopif.c: Added define
  2136. NETIF_INIT_SNMP(netif, type, speed) to initialize per-netif snmp variables,
  2137. added initialization of those to ethernetif, slipif and loopif.
  2138. 2007-05-18 Simon Goldschmidt
  2139. * opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF
  2140. (defaulting to off for now) that can be set to 0 to send fragmented
  2141. packets by passing PBUF_REFs down the stack.
  2142. 2007-05-23 Frédéric Bernon
  2143. * api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP
  2144. connections, such present in patch #5959.
  2145. 2007-05-23 Frédéric Bernon
  2146. * api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx
  2147. code in only one part...
  2148. 2007-05-18 Simon Goldschmidt
  2149. * opt.h, memp.h, memp.c: Added option MEMP_OVERFLOW_CHECK to check for memp
  2150. elements to overflow. This is achieved by adding some bytes before and after
  2151. each pool element (increasing their size, of course), filling them with a
  2152. prominent value and checking them on freeing the element.
  2153. Set it to 2 to also check every element in every pool each time memp_malloc()
  2154. or memp_free() is called (slower but more helpful).
  2155. 2007-05-10 Simon Goldschmidt
  2156. * opt.h, memp.h, memp.c, pbuf.c (see task #6831): use a new memp pool for
  2157. PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to reduce
  2158. code size.
  2159. 2007-05-11 Frédéric Bernon
  2160. * sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c:
  2161. Include a function pointer instead of a table index in the message to reduce
  2162. footprint. Disable some part of lwip_send and lwip_sendto if some options are
  2163. not set (LWIP_TCP, LWIP_UDP, LWIP_RAW).
  2164. 2007-05-10 Simon Goldschmidt
  2165. * *.h (except netif/ppp/*.h): Included patch #5448: include '#ifdef __cplusplus
  2166. \ extern "C" {' in all header files. Now you can write your application using
  2167. the lwIP stack in C++ and simply #include the core files. Note I have left
  2168. out the netif/ppp/*h header files for now, since I don't know which files are
  2169. included by applications and which are for internal use only.
  2170. 2007-05-09 Simon Goldschmidt
  2171. * opt.h, *.c/*.h: Included patch #5920: Create define to override C-library
  2172. memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for
  2173. situations where some compilers might inline the copy and save a function
  2174. call. Also replaced all calls to memcpy() with calls to (S)MEMCPY().
  2175. 2007-05-08 Simon Goldschmidt
  2176. * mem.h: If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc())
  2177. to be overriden in case the C-library malloc implementation is not protected
  2178. against concurrent access.
  2179. 2007-05-04 Simon Goldschmidt (Atte Kojo)
  2180. * etharp.c: Introduced fast one-entry-cache to speed up ARP lookup when sending
  2181. multiple packets to the same host.
  2182. 2007-05-04 Frédéric Bernon, Jonathan Larmour
  2183. * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible
  2184. to corrupt remote addr/port connection state". Reduce problems "not enought memory" with
  2185. netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between
  2186. sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function.
  2187. Warning, if you directly access to "fromaddr" & "fromport" field from netbuf struct,
  2188. these fields are now renamed "addr" & "port".
  2189. 2007-04-11 Jonathan Larmour
  2190. * sys.h, api_lib.c: Provide new sys_mbox_tryfetch function. Require ports to provide new
  2191. sys_arch_mbox_tryfetch function to get a message if one is there, otherwise return
  2192. with SYS_MBOX_EMPTY. sys_arch_mbox_tryfetch can be implemented as a function-like macro
  2193. by the port in sys_arch.h if desired.
  2194. 2007-04-06 Frédéric Bernon, Simon Goldschmidt
  2195. * opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option LWIP_NETIF_API
  2196. allow to use thread-safe functions to add/remove netif in list, and to start/stop dhcp
  2197. clients, using new functions from netifapi.h. Disable as default (no port change to do).
  2198. 2007-04-05 Frédéric Bernon
  2199. * sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more BSD compliant.
  2200. 2007-04-04 Simon Goldschmidt
  2201. * arch.h, api_msg.c, dhcp.c, msg_in.c, sockets.c: Introduced #define LWIP_UNUSED_ARG(x)
  2202. use this for and architecture-independent form to tell the compiler you intentionally
  2203. are not using this variable. Can be overriden in cc.h.
  2204. 2007-03-28 Frédéric Bernon
  2205. * opt.h, netif.h, dhcp.h, dhcp.c: New configuration option LWIP_NETIF_HOSTNAME allow to
  2206. define a hostname in netif struct (this is just a pointer, so, you can use a hardcoded
  2207. string, point on one of your's ethernetif field, or alloc a string you will free yourself).
  2208. It will be used by DHCP to register a client hostname, but can also be use when you call
  2209. snmp_set_sysname.
  2210. 2007-03-28 Frédéric Bernon
  2211. * netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to allow to
  2212. initialize a network interface's flag with. It tell this interface is an ethernet
  2213. device, and we can use ARP with it to do a "gratuitous ARP" (RFC 3220 "IP Mobility
  2214. Support for IPv4" section 4.6) when interface is "up" with netif_set_up().
  2215. 2007-03-26 Frédéric Bernon, Jonathan Larmour
  2216. * opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP init at build
  2217. time if you only use PPP or SLIP. The default is enable. Note we don't have to call
  2218. etharp_init in your port's initilization sequence if you use tcpip.c, because this call
  2219. is done in tcpip_init function.
  2220. 2007-03-22 Frédéric Bernon
  2221. * stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if necessary with the
  2222. new option LWIP_STATS_LARGE. If you need this option, define LWIP_STATS_LARGE to 1 in
  2223. your lwipopts.h. More, unused counters are not defined in the stats structs, and not
  2224. display by stats_display(). Note that some options (SYS_STATS and RAW_STATS) are defined
  2225. but never used. Fix msg_in.c with the correct #if test for a stat display.
  2226. 2007-03-21 Kieran Mansley
  2227. * netif.c, netif.h: Apply patch#4197 with some changes (originator: rireland@hmgsl.com).
  2228. Provides callback on netif up/down state change.
  2229. 2007-03-11 Frédéric Bernon, Mace Gael, Steve Reynolds
  2230. * sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, igmp.h, igmp.c,
  2231. ip.c, netif.h, tcpip.c, opt.h:
  2232. New configuration option LWIP_IGMP to enable IGMP processing. Based on only one
  2233. filter per all network interfaces. Declare a new function in netif to enable to
  2234. control the MAC filter (to reduce lwIP traffic processing).
  2235. 2007-03-11 Frédéric Bernon
  2236. * tcp.h, tcp.c, sockets.c, tcp_out.c, tcp_in.c, opt.h: Keepalive values can
  2237. be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this
  2238. unless you know what you're doing (default are RFC1122 compliant). Note
  2239. that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds.
  2240. 2007-03-08 Frédéric Bernon
  2241. * tcp.h: Keepalive values can be configured at compile time, but don't change
  2242. this unless you know what you're doing (default are RFC1122 compliant).
  2243. 2007-03-08 Frédéric Bernon
  2244. * sockets.c, api.h, api_lib.c, tcpip.c, sys.h, sys.c, err.c, opt.h:
  2245. Implement LWIP_SO_RCVTIMEO configuration option to enable/disable SO_RCVTIMEO
  2246. on UDP sockets/netconn.
  2247. 2007-03-08 Simon Goldschmidt
  2248. * snmp_msg.h, msg_in.c: SNMP UDP ports can be configured at compile time.
  2249. 2007-03-06 Frédéric Bernon
  2250. * api.h, api_lib.c, sockets.h, sockets.c, tcpip.c, sys.h, sys.c, err.h:
  2251. Implement SO_RCVTIMEO on UDP sockets/netconn.
  2252. 2007-02-28 Kieran Mansley (based on patch from Simon Goldschmidt)
  2253. * api_lib.c, tcpip.c, memp.c, memp.h: make API msg structs allocated
  2254. on the stack and remove the API msg type from memp
  2255. 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
  2256. * sockets.h, sockets.c: Move socket initialization to new
  2257. lwip_socket_init() function.
  2258. NOTE: this changes the API with ports. Ports will have to be
  2259. updated to call lwip_socket_init() now.
  2260. 2007-02-26 Jonathan Larmour (based on patch from Simon Goldschmidt)
  2261. * api_lib.c: Use memcpy in netbuf_copy_partial.
  2262. ++ Bug fixes:
  2263. 2008-03-17 Frédéric Bernon, Ed Kerekes
  2264. * igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have
  2265. some problems to fill the IP header on some targets, use now the
  2266. ip.h macros to do it).
  2267. 2008-03-13 Frédéric Bernon
  2268. * sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using
  2269. (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a
  2270. TCP connection caused a crash. Note that using (lwip_)recvfrom
  2271. like this is a bit slow and that using (lwip)getpeername is the
  2272. good lwip way to do it (so, using recv is faster on tcp sockets).
  2273. 2008-03-12 Frédéric Bernon, Jonathan Larmour
  2274. * api_msg.c, contrib/apps/ping.c: Fix bug #22530 "api_msg.c's
  2275. recv_raw() does not consume data", and the ping sample (with
  2276. LWIP_SOCKET=1, the code did the wrong supposition that lwip_recvfrom
  2277. returned the IP payload, without the IP header).
  2278. 2008-03-04 Jonathan Larmour
  2279. * mem.c, stats.c, mem.h: apply patch #6414 to avoid compiler errors
  2280. and/or warnings on some systems where mem_size_t and size_t differ.
  2281. * pbuf.c, ppp.c: Fix warnings on some systems with mem_malloc.
  2282. 2008-03-04 Kieran Mansley (contributions by others)
  2283. * Numerous small compiler error/warning fixes from contributions to
  2284. mailing list after 1.3.0 release candidate made.
  2285. 2008-01-25 Cui hengbin (integrated by Frédéric Bernon)
  2286. * dns.c: Fix bug #22108 "DNS problem" caused by unaligned structures.
  2287. 2008-01-15 Kieran Mansley
  2288. * tcp_out.c: BUG20511. Modify persist timer to start when we are
  2289. prevented from sending by a small send window, not just a zero
  2290. send window.
  2291. 2008-01-09 Jonathan Larmour
  2292. * opt.h, ip.c: Rename IP_OPTIONS define to IP_OPTIONS_ALLOWED to avoid
  2293. conflict with Linux system headers.
  2294. 2008-01-06 Jonathan Larmour
  2295. * dhcp.c: fix bug #19927: "DHCP NACK problem" by clearing any existing set IP
  2296. address entirely on receiving a DHCPNAK, and restarting discovery.
  2297. 2007-12-21 Simon Goldschmidt
  2298. * sys.h, api_lib.c, api_msg.c, sockets.c: fix bug #21698: "netconn->recv_avail
  2299. is not protected" by using new macros for interlocked access to modify/test
  2300. netconn->recv_avail.
  2301. 2007-12-20 Kieran Mansley (based on patch from Oleg Tyshev)
  2302. * tcp_in.c: fix bug# 21535 (nrtx not reset correctly in SYN_SENT state)
  2303. 2007-12-20 Kieran Mansley (based on patch from Per-Henrik Lundbolm)
  2304. * tcp.c, tcp_in.c, tcp_out.c, tcp.h: fix bug #20199 (better handling
  2305. of silly window avoidance and prevent lwIP from shrinking the window)
  2306. 2007-12-04 Simon Goldschmidt
  2307. * tcp.c, tcp_in.c: fix bug #21699 (segment leak in ooseq processing when last
  2308. data packet was lost): add assert that all segment lists are empty in
  2309. tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED
  2310. state from LAST_ACK in tcp_process
  2311. 2007-12-02 Simon Goldschmidt
  2312. * sockets.h: fix bug #21654: exclude definition of struct timeval from #ifndef FD_SET
  2313. If including <sys/time.h> for system-struct timeval, LWIP_TIMEVAL_PRIVATE now
  2314. has to be set to 0 in lwipopts.h
  2315. 2007-12-02 Simon Goldschmidt
  2316. * api_msg.c, api_lib.c: fix bug #21656 (recvmbox problem in netconn API): always
  2317. allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen
  2318. netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox.
  2319. This is a fix for thread-safety and allocates all items needed for a netconn
  2320. when the netconn is created.
  2321. 2007-11-30 Simon Goldschmidt
  2322. * udp.c: first attempt to fix bug #21655 (DHCP doesn't work reliably with multiple
  2323. netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed
  2324. to netif->dhcp->pcb only (if that exists) and not to any other pcb for the same
  2325. port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address)
  2326. 2007-11-27 Simon Goldschmidt
  2327. * ip.c: fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by
  2328. letting ip_route only use netifs that are up.
  2329. 2007-11-27 Simon Goldschmidt
  2330. * err.h, api_lib.c, api_msg.c, sockets.c: Changed error handling: ERR_MEM, ERR_BUF
  2331. and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and
  2332. sockets block most operations once they have seen a fatal error.
  2333. 2007-11-27 Simon Goldschmidt
  2334. * udp.h, udp.c, dhcp.c: Implemented new function udp_sendto_if which takes the
  2335. netif to send as an argument (to be able to send on netifs that are down).
  2336. 2007-11-26 Simon Goldschmidt
  2337. * tcp_in.c: Fixed bug #21582: pcb->acked accounting can be wrong when ACKs
  2338. arrive out-of-order
  2339. 2007-11-21 Simon Goldschmidt
  2340. * tcp.h, tcp_out.c, api_msg.c: Fixed bug #20287: tcp_output_nagle sends too early
  2341. Fixed the nagle algorithm; nagle now also works for all raw API applications
  2342. and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY'
  2343. 2007-11-12 Frédéric Bernon
  2344. * sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most
  2345. of the netconn_peer and netconn_addr processing is done inside tcpip_thread
  2346. context in do_getaddr.
  2347. 2007-11-10 Simon Goldschmidt
  2348. * etharp.c: Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can
  2349. happen any time). Now the packet simply isn't enqueued when out of memory.
  2350. 2007-11-01 Simon Goldschmidt
  2351. * tcp.c, tcp_in.c: Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or
  2352. TCP_MSS if that is smaller) as long as no MSS option is received from the
  2353. remote host.
  2354. 2007-11-01 Simon Goldschmidt
  2355. * tcp.h, tcp.c, tcp_in.c: Fixed bug #21491: The MSS option sent (with SYN)
  2356. is now based on TCP_MSS instead of pcb->mss (on passive open now effectively
  2357. sending our configured TCP_MSS instead of the one received).
  2358. 2007-11-01 Simon Goldschmidt
  2359. * tcp_in.c: Fixed bug #21181: On active open, the initial congestion window was
  2360. calculated based on the configured TCP_MSS, not on the MSS option received
  2361. with SYN+ACK.
  2362. 2007-10-09 Simon Goldschmidt
  2363. * udp.c, inet.c, inet.h: Fixed UDPLite: send: Checksum was always generated too
  2364. short and also was generated wrong if checksum coverage != tot_len;
  2365. receive: checksum was calculated wrong if checksum coverage != tot_len
  2366. 2007-10-08 Simon Goldschmidt
  2367. * mem.c: lfree was not updated in mem_realloc!
  2368. 2007-10-07 Frédéric Bernon
  2369. * sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential
  2370. crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT:
  2371. this change cause an API breakage for netconn_addr, since a parameter
  2372. type change. Any compiler should cause an error without any changes in
  2373. yours netconn_peer calls (so, it can't be a "silent change"). It also
  2374. reduce a little bit the footprint for socket layer (lwip_getpeername &
  2375. lwip_getsockname use now a common lwip_getaddrname function since
  2376. netconn_peer & netconn_addr have the same parameters).
  2377. 2007-09-20 Simon Goldschmidt
  2378. * tcp.c: Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state)
  2379. by checking tcp_tw_pcbs also
  2380. 2007-09-19 Simon Goldschmidt
  2381. * icmp.c: Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies)
  2382. 2007-09-15 Mike Kleshov
  2383. * mem.c: Fixed bug #21077 (inaccuracy in calculation of lwip_stat.mem.used)
  2384. 2007-09-06 Frédéric Bernon
  2385. * several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove
  2386. it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which
  2387. already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h"
  2388. if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h.
  2389. 2007-08-30 Frédéric Bernon
  2390. * igmp.h, igmp.c: Some changes to remove some redundant code, add some traces,
  2391. and fix some coding style.
  2392. 2007-08-28 Frédéric Bernon
  2393. * tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any
  2394. kind of packets. These packets are considered like Ethernet packets (payload
  2395. pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets
  2396. are considered like IP packets (payload pointing to iphdr).
  2397. 2007-08-27 Frédéric Bernon
  2398. * api.h, api_lib.c, api_msg.c: First fix for "bug #20900 : Potential crash error
  2399. problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state
  2400. and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT).
  2401. 2007-08-24 Kieran Mansley
  2402. * inet.c Modify (acc >> 16) test to ((acc >> 16) != 0) to help buggy
  2403. compiler (Paradigm C++)
  2404. 2007-08-09 Frédéric Bernon, Bill Florac
  2405. * stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP Improvement.
  2406. Introduce IGMP_STATS to centralize statistics management.
  2407. 2007-08-09 Frédéric Bernon, Bill Florac
  2408. * udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast
  2409. packet on a udp pcb binded on an netif's IP address, and not on "any".
  2410. 2007-08-09 Frédéric Bernon, Bill Florac
  2411. * igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP Improvement.
  2412. This is mainly on using lookup/lookfor, and some coding styles...
  2413. 2007-07-26 Frédéric Bernon (and "thedoctor")
  2414. * igmp.c: Fix bug #20595 to accept IGMPv3 "Query" messages.
  2415. 2007-07-25 Simon Goldschmidt
  2416. * api_msg.c, tcp.c: Another fix for bug #20021: by not returning an error if
  2417. tcp_output fails in tcp_close, the code in do_close_internal gets simpler
  2418. (tcp_output is called again later from tcp timers).
  2419. 2007-07-25 Simon Goldschmidt
  2420. * ip_frag.c: Fixed bug #20429: use the new pbuf_copy_partial instead of the old
  2421. copy_from_pbuf, which illegally modified the given pbuf.
  2422. 2007-07-25 Simon Goldschmidt
  2423. * tcp_out.c: tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs:
  2424. changed snd_queuelen++ to snd_queuelen += pbuf_clen(p).
  2425. 2007-07-24 Simon Goldschmidt
  2426. * api_msg.c, tcp.c: Fix bug #20480: Check the pcb passed to tcp_listen() for the
  2427. correct state (must be CLOSED).
  2428. 2007-07-13 Thomas Taranowski (commited by Jared Grubb)
  2429. * memp.c: Fix bug #20478: memp_malloc returned NULL+MEMP_SIZE on failed
  2430. allocation. It now returns NULL.
  2431. 2007-07-13 Frédéric Bernon
  2432. * api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in
  2433. all error cases.
  2434. 2007-07-13 Frédéric Bernon
  2435. * api_msg.c: Fix bug #20315: possible memory leak problem if tcp_listen failed,
  2436. because current code doesn't follow rawapi.txt documentation.
  2437. 2007-07-13 Kieran Mansley
  2438. * src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in
  2439. out of sequence processing of received packets
  2440. 2007-07-03 Simon Goldschmidt
  2441. * nearly-all-files: Added assertions where PBUF_RAM pbufs are used and an
  2442. assumption is made that this pbuf is in one piece (i.e. not chained). These
  2443. assumptions clash with the possibility of converting to fully pool-based
  2444. pbuf implementations, where PBUF_RAM pbufs might be chained.
  2445. 2007-07-03 Simon Goldschmidt
  2446. * api.h, api_lib.c, api_msg.c: Final fix for bug #20021 and some other problems
  2447. when closing tcp netconns: removed conn->sem, less context switches when
  2448. closing, both netconn_close and netconn_delete should safely close tcp
  2449. connections.
  2450. 2007-07-02 Simon Goldschmidt
  2451. * ipv4/ip.h, ipv6/ip.h, opt.h, netif.h, etharp.h, ipv4/ip.c, netif.c, raw.c,
  2452. tcp_out.c, udp.c, etharp.c: Added option LWIP_NETIF_HWADDRHINT (default=off)
  2453. to cache ARP table indices with each pcb instead of single-entry cache for
  2454. the complete stack.
  2455. 2007-07-02 Simon Goldschmidt
  2456. * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent
  2457. warnings when assigning to smaller types.
  2458. 2007-06-28 Simon Goldschmidt
  2459. * tcp_out.c: Added check to prevent tcp_pcb->snd_queuelen from overflowing.
  2460. 2007-06-28 Simon Goldschmidt
  2461. * tcp.h: Fixed bug #20287: Fixed nagle algorithm (sending was done too early if
  2462. a segment contained chained pbufs)
  2463. 2007-06-28 Frédéric Bernon
  2464. * autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute
  2465. a "pseudo-random" value based on netif's MAC and some autoip fields. It's always
  2466. possible to define this macro in your own lwipopts.h to always use C library's
  2467. rand(). Note that autoip_create_rand_addr doesn't use this macro.
  2468. 2007-06-28 Frédéric Bernon
  2469. * netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option
  2470. LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications
  2471. in api_lib/api_msg (use pointers and not type with table, etc...)
  2472. 2007-06-26 Simon Goldschmidt
  2473. * udp.h: Fixed bug #20259: struct udp_hdr was lacking the packin defines.
  2474. 2007-06-25 Simon Goldschmidt
  2475. * udp.c: Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload
  2476. for udp packets with no matching pcb.
  2477. 2007-06-25 Simon Goldschmidt
  2478. * udp.c: Fixed bug #20220: UDP PCB search in udp_input(): a non-local match
  2479. could get udp input packets if the remote side matched.
  2480. 2007-06-13 Simon Goldschmidt
  2481. * netif.c: Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get
  2482. changed in netif_set_ipaddr if previous netif->ip_addr.addr was 0.
  2483. 2007-06-13 Simon Goldschmidt
  2484. * api_msg.c: pcb_new sets conn->err if protocol is not implemented
  2485. -> netconn_new_..() does not allocate a new connection for unsupported
  2486. protocols.
  2487. 2007-06-13 Frédéric Bernon, Simon Goldschmidt
  2488. * api_lib.c: change return expression in netconn_addr and netconn_peer, because
  2489. conn->err was reset to ERR_OK without any reasons (and error was lost)...
  2490. 2007-06-13 Frédéric Bernon, Matthias Weisser
  2491. * opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename
  2492. MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid
  2493. some macro names collision with some OS macros.
  2494. 2007-06-11 Simon Goldschmidt
  2495. * udp.c: UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0,
  2496. create checksum over the complete packet. On RX, if it's < 8 (and not 0),
  2497. discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both
  2498. UDP & UDP Lite.
  2499. 2007-06-11 Srinivas Gollakota & Oleg Tyshev
  2500. * tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP flags"
  2501. where TCP flags wasn't initialized in tcp_keepalive.
  2502. 2007-06-03 Simon Goldschmidt
  2503. * udp.c: udp_input(): Input pbuf was not freed if pcb had no recv function
  2504. registered, p->payload was modified without modifying p->len if sending
  2505. icmp_dest_unreach() (had no negative effect but was definitively wrong).
  2506. 2007-06-03 Simon Goldschmidt
  2507. * icmp.c: Corrected bug #19937: For responding to an icmp echo request, icmp
  2508. re-used the input pbuf even if that didn't have enough space to include the
  2509. link headers. Now the space is tested and a new pbuf is allocated for the
  2510. echo response packet if the echo request pbuf isn't big enough.
  2511. 2007-06-01 Simon Goldschmidt
  2512. * sockets.c: Checked in patch #5914: Moved sockopt processing into tcpip_thread.
  2513. 2007-05-23 Frédéric Bernon
  2514. * api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only
  2515. allocated by do_listen if success) and netconn_accept errors handling. In
  2516. most of api_lib functions, we replace some errors checkings like "if (conn==NULL)"
  2517. by ASSERT, except for netconn_delete.
  2518. 2007-05-23 Frédéric Bernon
  2519. * api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return
  2520. an error code if it's impossible to fetch a pbuf on a TCP connection (and not
  2521. directly close the recvmbox).
  2522. 2007-05-22 Simon Goldschmidt
  2523. * tcp.c: Fixed bug #1895 (tcp_bind not correct) by introducing a list of
  2524. bound but unconnected (and non-listening) tcp_pcbs.
  2525. 2007-05-22 Frédéric Bernon
  2526. * sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only
  2527. used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of
  2528. sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features
  2529. like "sys_timeout" in their application threads.
  2530. 2007-05-22 Frédéric Bernon
  2531. * api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see
  2532. which parameters are used by which do_xxx function, and to avoid "misusing"
  2533. parameters (patch #5938).
  2534. 2007-05-22 Simon Goldschmidt
  2535. * api_lib.c, api_msg.c, raw.c, api.h, api_msg.h, raw.h: Included patch #5938:
  2536. changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto
  2537. is only 8 bits wide. This affects the api, as there, the protocol was
  2538. u16_t, too.
  2539. 2007-05-18 Simon Goldschmidt
  2540. * memp.c: addition to patch #5913: smaller pointer was returned but
  2541. memp_memory was the same size -> did not save memory.
  2542. 2007-05-16 Simon Goldschmidt
  2543. * loopif.c, slipif.c: Fix bug #19729: free pbuf if netif->input() returns
  2544. != ERR_OK.
  2545. 2007-05-16 Simon Goldschmidt
  2546. * api_msg.c, udp.c: If a udp_pcb has a local_ip set, check if it is the same
  2547. as the one of the netif used for sending to prevent sending from old
  2548. addresses after a netif address gets changed (partly fixes bug #3168).
  2549. 2007-05-16 Frédéric Bernon
  2550. * tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work
  2551. with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in
  2552. tcpip_init) because we have to be sure that network interfaces are already
  2553. added (mac filter is updated only in igmp_init for the moment).
  2554. 2007-05-16 Simon Goldschmidt
  2555. * mem.c, memp.c: Removed semaphores from memp, changed sys_sem_wait calls
  2556. into sys_arch_sem_wait calls to prevent timers from running while waiting
  2557. for the heap. This fixes bug #19167.
  2558. 2007-05-13 Simon Goldschmidt
  2559. * tcp.h, sockets.h, sockets.c: Fixed bug from patch #5865 by moving the defines
  2560. for socket options (lwip_set/-getsockopt) used with level IPPROTO_TCP from
  2561. tcp.h to sockets.h.
  2562. 2007-05-07 Simon Goldschmidt
  2563. * mem.c: Another attempt to fix bug #17922.
  2564. 2007-05-04 Simon Goldschmidt
  2565. * pbuf.c, pbuf.h, etharp.c: Further update to ARP queueing: Changed pbuf_copy()
  2566. implementation so that it can be reused (don't allocate the target
  2567. pbuf inside pbuf_copy()).
  2568. 2007-05-04 Simon Goldschmidt
  2569. * memp.c: checked in patch #5913: in memp_malloc() we can return memp as mem
  2570. to save a little RAM (next pointer of memp is not used while not in pool).
  2571. 2007-05-03 "maq"
  2572. * sockets.c: Fix ioctl FIONREAD when some data remains from last recv.
  2573. (patch #3574).
  2574. 2007-04-23 Simon Goldschmidt
  2575. * loopif.c, loopif.h, opt.h, src/netif/FILES: fix bug #2595: "loopif results
  2576. in NULL reference for incoming TCP packets". Loopif has to be configured
  2577. (using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input()
  2578. (multithreading environments, e.g. netif->input() = tcpip_input()) or
  2579. putting packets on a list that is fed to the stack by calling loopif_poll()
  2580. (single-thread / NO_SYS / polling environment where e.g.
  2581. netif->input() = ip_input).
  2582. 2007-04-17 Jonathan Larmour
  2583. * pbuf.c: Use s32_t in pbuf_realloc(), as an s16_t can't reliably hold
  2584. the difference between two u16_t's.
  2585. * sockets.h: FD_SETSIZE needs to match number of sockets, which is
  2586. MEMP_NUM_NETCONN in sockets.c right now.
  2587. 2007-04-12 Jonathan Larmour
  2588. * icmp.c: Reset IP header TTL in ICMP ECHO responses (bug #19580).
  2589. 2007-04-12 Kieran Mansley
  2590. * tcp.c, tcp_in.c, tcp_out.c, tcp.h: Modify way the retransmission
  2591. timer is reset to fix bug#19434, with help from Oleg Tyshev.
  2592. 2007-04-11 Simon Goldschmidt
  2593. * etharp.c, pbuf.c, pbuf.h: 3rd fix for bug #11400 (arp-queuing): More pbufs than
  2594. previously thought need to be copied (everything but PBUF_ROM!). Cleaned up
  2595. pbuf.c: removed functions no needed any more (by etharp).
  2596. 2007-04-11 Kieran Mansley
  2597. * inet.c, ip_addr.h, sockets.h, sys.h, tcp.h: Apply patch #5745: Fix
  2598. "Constant is long" warnings with 16bit compilers. Contributed by
  2599. avatar@mmlab.cse.yzu.edu.tw
  2600. 2007-04-05 Frédéric Bernon, Jonathan Larmour
  2601. * api_msg.c: Fix bug #16830: "err_tcp() posts to connection mailbox when no pend on
  2602. the mailbox is active". Now, the post is only done during a connect, and do_send,
  2603. do_write and do_join_leave_group don't do anything if a previous error was signaled.
  2604. 2007-04-03 Frédéric Bernon
  2605. * ip.c: Don't set the IP_DF ("Don't fragment") flag in the IP header in IP output
  2606. packets. See patch #5834.
  2607. 2007-03-30 Frédéric Bernon
  2608. * api_msg.c: add a "pcb_new" helper function to avoid redundant code, and to add
  2609. missing pcb allocations checking (in do_bind, and for each raw_new). Fix style.
  2610. 2007-03-30 Frédéric Bernon
  2611. * most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with
  2612. others environment defines (these were too "generic").
  2613. 2007-03-28 Frédéric Bernon
  2614. * api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal pbuf_alloc call
  2615. result and can cause a crash. lwip_send now check netbuf_ref result.
  2616. 2007-03-28 Simon Goldschmidt
  2617. * sockets.c Remove "#include <errno.h>" from sockets.c to avoid multiple
  2618. definition of macros (in errno.h and lwip/arch.h) if LWIP_PROVIDE_ERRNO is
  2619. defined. This is the way it should have been already (looking at
  2620. doc/sys_arch.txt)
  2621. 2007-03-28 Kieran Mansley
  2622. * opt.h Change default PBUF_POOL_BUFSIZE (again) to accomodate default MSS +
  2623. IP and TCP headers *and* physical link headers
  2624. 2007-03-26 Frédéric Bernon (based on patch from Dmitry Potapov)
  2625. * api_lib.c: patch for netconn_write(), fixes a possible race condition which cause
  2626. to send some garbage. It is not a definitive solution, but the patch does solve
  2627. the problem for most cases.
  2628. 2007-03-22 Frédéric Bernon
  2629. * api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never used).
  2630. 2007-03-22 Frédéric Bernon
  2631. * api_lib.c: somes resources couldn't be freed if there was errors during
  2632. netconn_new_with_proto_and_callback.
  2633. 2007-03-22 Frédéric Bernon
  2634. * ethernetif.c: update netif->input calls to check return value. In older ports,
  2635. it's a good idea to upgrade them, even if before, there could be another problem
  2636. (access to an uninitialized mailbox).
  2637. 2007-03-21 Simon Goldschmidt
  2638. * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed
  2639. by casting to unsigned).
  2640. 2007-03-21 Frédéric Bernon
  2641. * api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from
  2642. api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a
  2643. dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call.
  2644. Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a
  2645. faster and more reliable communication between api_lib and tcpip.
  2646. 2007-03-21 Frédéric Bernon
  2647. * opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to 0.
  2648. 2007-03-21 Frédéric Bernon
  2649. * api_msg.c, igmp.c, igmp.h: Fix C++ style comments
  2650. 2007-03-21 Kieran Mansley
  2651. * opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS +
  2652. IP and TCP headers
  2653. 2007-03-21 Kieran Mansley
  2654. * Fix all uses of pbuf_header to check the return value. In some
  2655. cases just assert if it fails as I'm not sure how to fix them, but
  2656. this is no worse than before when they would carry on regardless
  2657. of the failure.
  2658. 2007-03-21 Kieran Mansley
  2659. * sockets.c, igmp.c, igmp.h, memp.h: Fix C++ style comments and
  2660. comment out missing header include in icmp.c
  2661. 2007-03-20 Frédéric Bernon
  2662. * memp.h, stats.c: Fix stats_display function where memp_names table wasn't
  2663. synchronized with memp.h.
  2664. 2007-03-20 Frédéric Bernon
  2665. * tcpip.c: Initialize tcpip's mbox, and verify if initialized in tcpip_input,
  2666. tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init problem with
  2667. network interfaces. Also fix a compiler warning.
  2668. 2007-03-20 Kieran Mansley
  2669. * udp.c: Only try and use pbuf_header() to make space for headers if
  2670. not a ROM or REF pbuf.
  2671. 2007-03-19 Frédéric Bernon
  2672. * api_msg.h, api_msg.c, tcpip.h, tcpip.c: Add return types to tcpip_apimsg()
  2673. and api_msg_post().
  2674. 2007-03-19 Frédéric Bernon
  2675. * Remove unimplemented "memp_realloc" function from memp.h.
  2676. 2007-03-11 Simon Goldschmidt
  2677. * pbuf.c: checked in patch #5796: pbuf_alloc: len field claculation caused
  2678. memory corruption.
  2679. 2007-03-11 Simon Goldschmidt (based on patch from Dmitry Potapov)
  2680. * api_lib.c, sockets.c, api.h, api_msg.h, sockets.h: Fixed bug #19251
  2681. (missing `const' qualifier in socket functions), to get more compatible to
  2682. standard POSIX sockets.
  2683. 2007-03-11 Frédéric Bernon (based on patch from Dmitry Potapov)
  2684. * sockets.c: Add asserts inside bind, connect and sendto to check input
  2685. parameters. Remove excessive set_errno() calls after get_socket(), because
  2686. errno is set inside of get_socket(). Move last sock_set_errno() inside
  2687. lwip_close.
  2688. 2007-03-09 Simon Goldschmidt
  2689. * memp.c: Fixed bug #11400: New etharp queueing introduced bug: memp_memory
  2690. was allocated too small.
  2691. 2007-03-06 Simon Goldschmidt
  2692. * tcpip.c: Initialize dhcp timers in tcpip_thread (if LWIP_DHCP) to protect
  2693. the stack from concurrent access.
  2694. 2007-03-06 Frédéric Bernon, Dmitry Potapov
  2695. * tcpip.c, ip_frag.c, ethernetif.c: Fix some build problems, and a redundancy
  2696. call to "lwip_stats.link.recv++;" in low_level_input() & ethernetif_input().
  2697. 2007-03-06 Simon Goldschmidt
  2698. * ip_frag.c, ip_frag.h: Reduce code size: don't include code in those files
  2699. if IP_FRAG == 0 and IP_REASSEMBLY == 0
  2700. 2007-03-06 Frédéric Bernon, Simon Goldschmidt
  2701. * opt.h, ip_frag.h, tcpip.h, tcpip.c, ethernetif.c: add new configuration
  2702. option named ETHARP_TCPIP_ETHINPUT, which enable the new tcpip_ethinput.
  2703. Allow to do ARP processing for incoming packets inside tcpip_thread
  2704. (protecting ARP layer against concurrent access). You can also disable
  2705. old code using tcp_input with new define ETHARP_TCPIP_INPUT set to 0.
  2706. Older ports have to use tcpip_ethinput.
  2707. 2007-03-06 Simon Goldschmidt (based on patch from Dmitry Potapov)
  2708. * err.h, err.c: fixed compiler warning "initialization dircards qualifiers
  2709. from pointer target type"
  2710. 2007-03-05 Frédéric Bernon
  2711. * opt.h, sockets.h: add new configuration options (LWIP_POSIX_SOCKETS_IO_NAMES,
  2712. ETHARP_TRUST_IP_MAC, review SO_REUSE)
  2713. 2007-03-04 Frédéric Bernon
  2714. * api_msg.c: Remove some compiler warnings : parameter "pcb" was never
  2715. referenced.
  2716. 2007-03-04 Frédéric Bernon
  2717. * api_lib.c: Fix "[patch #5764] api_lib.c cleanup: after patch #5687" (from
  2718. Dmitry Potapov).
  2719. The api_msg struct stay on the stack (not moved to netconn struct).
  2720. 2007-03-04 Simon Goldschmidt (based on patch from Dmitry Potapov)
  2721. * pbuf.c: Fix BUG#19168 - pbuf_free can cause deadlock (if
  2722. SYS_LIGHTWEIGHT_PROT=1 & freeing PBUF_RAM when mem_sem is not available)
  2723. Also fixed cast warning in pbuf_alloc()
  2724. 2007-03-04 Simon Goldschmidt
  2725. * etharp.c, etharp.h, memp.c, memp.h, opt.h: Fix BUG#11400 - don't corrupt
  2726. existing pbuf chain when enqueuing multiple pbufs to a pending ARP request
  2727. 2007-03-03 Frédéric Bernon
  2728. * udp.c: remove obsolete line "static struct udp_pcb *pcb_cache = NULL;"
  2729. It is static, and never used in udp.c except udp_init().
  2730. 2007-03-02 Simon Goldschmidt
  2731. * tcpip.c: Moved call to ip_init(), udp_init() and tcp_init() from
  2732. tcpip_thread() to tcpip_init(). This way, raw API connections can be
  2733. initialized before tcpip_thread is running (e.g. before OS is started)
  2734. 2007-03-02 Frédéric Bernon
  2735. * rawapi.txt: Fix documentation mismatch with etharp.h about etharp_tmr's call
  2736. interval.
  2737. 2007-02-28 Kieran Mansley
  2738. * pbuf.c: Fix BUG#17645 - ensure pbuf payload pointer is not moved
  2739. outside the region of the pbuf by pbuf_header()
  2740. 2007-02-28 Kieran Mansley
  2741. * sockets.c: Fix BUG#19161 - ensure milliseconds timeout is non-zero
  2742. when supplied timeout is also non-zero
  2743. (STABLE-1.2.0)
  2744. 2006-12-05 Leon Woestenberg
  2745. * CHANGELOG: Mention STABLE-1.2.0 release.
  2746. ++ New features:
  2747. 2006-12-01 Christiaan Simons
  2748. * mem.h, opt.h: Added MEM_LIBC_MALLOC option.
  2749. Note this is a workaround. Currently I have no other options left.
  2750. 2006-10-26 Christiaan Simons (accepted patch by Jonathan Larmour)
  2751. * ipv4/ip_frag.c: rename MAX_MTU to IP_FRAG_MAX_MTU and move define
  2752. to include/lwip/opt.h.
  2753. * ipv4/lwip/ip_frag.h: Remove unused IP_REASS_INTERVAL.
  2754. Move IP_REASS_MAXAGE and IP_REASS_BUFSIZE to include/lwip/opt.h.
  2755. * opt.h: Add above new options.
  2756. 2006-08-18 Christiaan Simons
  2757. * tcp_{in,out}.c: added SNMP counters.
  2758. * ipv4/ip.c: added SNMP counters.

  2768. * snmp/asn1_{enc,dec}.c added
  2769. * snmp/mib2.c added
  2770. * snmp/msg_{in,out}.c added
  2771. * include/lwip/snmp_asn1.h added
  2772. * include/lwip/snmp_msg.h added
  2773. * doc/snmp_agent.txt added
  2774. 2006-03-29 Christiaan Simons
  2775. * inet.c, inet.h: Added platform byteswap support.
  2776. Added LWIP_PLATFORM_BYTESWAP define (defaults to 0) and
  2777. optional LWIP_PLATFORM_HTONS(), LWIP_PLATFORM_HTONL() macros.
  2778. ++ Bug fixes:
  2779. 2006-11-30 Christiaan Simons

  2783. 2006-10-11 Christiaan Simons
  2784. * api_lib.c etharp.c, ip.c, memp.c, stats.c, sys.{c,h} tcp.h:
  2785. Partially accepted patch #5449 for ANSI C compatibility / build fixes.
  2786. * ipv4/lwip/ip.h ipv6/lwip/ip.h: Corrected UDP-Lite protocol
  2787. identifier from 170 to 136 (bug #17574).
  2788. 2006-10-10 Christiaan Simons
  2789. * api_msg.c: Fixed Nagle algorithm as reported by Bob Grice.
  2790. 2006-08-17 Christiaan Simons
  2791. * udp.c: Fixed bug #17200, added check for broadcast
  2792. destinations for PCBs bound to a unicast address.
  2793. 2006-08-07 Christiaan Simons
  2794. * api_msg.c: Flushing TCP output in do_close() (bug #15926).
  2795. 2006-06-27 Christiaan Simons
  2796. * api_msg.c: Applied patch for cold case (bug #11135).
  2797. In accept_function() ensure newconn->callback is always initialized.
  2798. 2006-06-15 Christiaan Simons
  2799. * mem.h: added MEM_SIZE_F alias to fix an ancient cold case (bug #1748),
  2800. facilitate printing of mem_size_t and u16_t statistics.
  2801. 2006-06-14 Christiaan Simons
  2802. * api_msg.c: Applied patch #5146 to handle allocation failures
  2803. in accept() by Kevin Lawson.
  2804. 2006-05-26 Christiaan Simons
  2805. * api_lib.c: Removed conn->sem creation and destruction
  2806. from netconn_write() and added sys_sem_new to netconn_new_*.
  2807. (STABLE-1_1_1)
  2808. 2006-03-03 Christiaan Simons
  2809. * ipv4/ip_frag.c: Added bound-checking assertions on ip_reassbitmap
  2810. access and added pbuf_alloc() return value checks.
  2811. 2006-01-01 Leon Woestenberg <leon.woestenberg@gmx.net>
  2812. * tcp_{in,out}.c, tcp_out.c: Removed 'even sndbuf' fix in TCP, which is
  2813. now handled by the checksum routine properly.
  2814. 2006-02-27 Leon Woestenberg <leon.woestenberg@gmx.net>
  2815. * pbuf.c: Fix alignment; pbuf_init() would not work unless
  2816. pbuf_pool_memory[] was properly aligned. (Patch by Curt McDowell.)
  2817. 2005-12-20 Leon Woestenberg <leon.woestenberg@gmx.net>
  2818. * tcp.c: Remove PCBs which stay in LAST_ACK state too long. Patch
  2819. submitted by Mitrani Hiroshi.
  2820. 2005-12-15 Christiaan Simons
  2821. * inet.c: Disabled the added summing routine to preserve code space.
  2822. 2005-12-14 Leon Woestenberg <leon.woestenberg@gmx.net>
  2823. * tcp_in.c: Duplicate FIN ACK race condition fix by Kelvin Lawson.
  2824. Added Curt McDowell's optimized checksumming routine for future
  2825. inclusion. Need to create test case for unaliged, aligned, odd,
  2826. even length combination of cases on various endianess machines.
  2827. 2005-12-09 Christiaan Simons
  2828. * inet.c: Rewrote standard checksum routine in proper portable C.
  2829. 2005-11-25 Christiaan Simons
  2830. * udp.c tcp.c: Removed SO_REUSE hack. Should reside in socket code only.
  2831. * *.c: introduced cc.h LWIP_DEBUG formatters matching the u16_t, s16_t,
  2832. u32_t, s32_t typedefs. This solves most debug word-length assumes.
  2833. 2005-07-17 Leon Woestenberg <leon.woestenberg@gmx.net>
  2834. * inet.c: Fixed unaligned 16-bit access in the standard checksum
  2835. routine by Peter Jolasson.
  2836. * slipif.c: Fixed implementation assumption of single-pbuf datagrams.
  2837. 2005-02-04 Leon Woestenberg <leon.woestenberg@gmx.net>
  2838. * tcp_out.c: Fixed uninitialized 'queue' referenced in memerr branch.
  2839. * tcp_{out|in}.c: Applied patch fixing unaligned access.
  2840. 2005-01-04 Leon Woestenberg <leon.woestenberg@gmx.net>
  2841. * pbuf.c: Fixed missing semicolon after LWIP_DEBUG statement.
  2842. 2005-01-03 Leon Woestenberg <leon.woestenberg@gmx.net>
  2843. * udp.c: UDP pcb->recv() was called even when it was NULL.
  2844. (STABLE-1_1_0)
  2845. 2004-12-28 Leon Woestenberg <leon.woestenberg@gmx.net>
  2846. * etharp.*: Disabled multiple packets on the ARP queue.
  2847. This clashes with TCP queueing.
  2848. 2004-11-28 Leon Woestenberg <leon.woestenberg@gmx.net>
  2849. * etharp.*: Fixed race condition from ARP request to ARP timeout.
  2850. Halved the ARP period, doubled the period counts.
  2851. ETHARP_MAX_PENDING now should be at least 2. This prevents
  2852. the counter from reaching 0 right away (which would allow
  2853. too little time for ARP responses to be received).
  2854. 2004-11-25 Leon Woestenberg <leon.woestenberg@gmx.net>
  2855. * dhcp.c: Decline messages were not multicast but unicast.
  2856. * etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
  2857. Do not try hard to insert arbitrary packet's source address,
  2858. etharp_ip_input() now calls etharp_update() without ETHARP_TRY_HARD.
  2859. etharp_query() now always DOES call ETHARP_TRY_HARD so that users
  2860. querying an address will see it appear in the cache (DHCP could
  2861. suffer from this when a server invalidly gave an in-use address.)
  2862. * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
  2863. comparing network addresses (identifiers), not the network masks
  2864. themselves.
  2865. * ipv4/ip_addr.c: ip_addr_isbroadcast() now checks that the given
  2866. IP address actually belongs to the network of the given interface.
  2867. 2004-11-24 Kieran Mansley <kjm25@cam.ac.uk>
  2868. * tcp.c: Increment pcb->snd_buf when ACK is received in SYN_SENT state.
  2869. (STABLE-1_1_0-RC1)
  2870. 2004-10-16 Kieran Mansley <kjm25@cam.ac.uk>
  2871. * tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
  2872. even if one is already pending, if the rcv_wnd is above a threshold
  2873. (currently TCP_WND/2). This avoids waiting for a timer to expire to send a
  2874. delayed ACK in order to open the window if the stack is only receiving data.
  2875. 2004-09-12 Kieran Mansley <kjm25@cam.ac.uk>
  2876. * tcp*.*: Retransmit time-out handling improvement by Sam Jansen.
  2877. 2004-08-20 Tony Mountifield <tony@softins.co.uk>
  2878. * etharp.c: Make sure the first pbuf queued on an ARP entry
  2879. is properly ref counted.
  2880. 2004-07-27 Tony Mountifield <tony@softins.co.uk>
  2881. * debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
  2882. warnings about comparison.
  2883. * pbuf.c: Stopped compiler complaining of empty if statement
  2884. when LWIP_DEBUGF() empty. Closed an unclosed comment.
  2885. * tcp.c: Stopped compiler complaining of empty if statement
  2886. when LWIP_DEBUGF() empty.
  2887. * ip.h Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
  2888. * inet.c: Added a couple of casts to quiet the compiler.
  2889. No need to test isascii(c) before isdigit(c) or isxdigit(c).
  2890. 2004-07-22 Tony Mountifield <tony@softins.co.uk>
  2891. * inet.c: Made data types consistent in inet_ntoa().
  2892. Added casts for return values of checksum routines, to pacify compiler.
  2893. * ip_frag.c, tcp_out.c, sockets.c, pbuf.c
  2894. Small corrections to some debugging statements, to pacify compiler.
  2895. 2004-07-21 Tony Mountifield <tony@softins.co.uk>
  2896. * etharp.c: Removed spurious semicolon and added missing end-of-comment.
  2897. * ethernetif.c Updated low_level_output() to match prototype for
  2898. netif->linkoutput and changed low_level_input() similarly for consistency.
  2899. * api_msg.c: Changed recv_raw() from int to u8_t, to match prototype
  2900. of raw_recv() in raw.h and so avoid compiler error.
  2901. * sockets.c: Added trivial (int) cast to keep compiler happier.
  2902. * ip.c, netif.c Changed debug statements to use the tidier ip4_addrN() macros.
  2903. (STABLE-1_0_0)
  2904. ++ Changes:
  2905. 2004-07-05 Leon Woestenberg <leon.woestenberg@gmx.net>
  2906. * sockets.*: Restructured LWIP_PRIVATE_TIMEVAL. Make sure
  2907. your cc.h file defines this either 1 or 0. If non-defined,
  2908. defaults to 1.
  2909. * .c: Added <string.h> and <errno.h> includes where used.
  2910. * etharp.c: Made some array indices unsigned.
  2911. 2004-06-27 Leon Woestenberg <leon.woestenberg@gmx.net>
  2912. * netif.*: Added netif_set_up()/down().
  2913. * dhcp.c: Changes to restart program flow.
  2914. 2004-05-07 Leon Woestenberg <leon.woestenberg@gmx.net>
  2915. * etharp.c: In find_entry(), instead of a list traversal per candidate, do a
  2916. single-pass lookup for different candidates. Should exploit locality.
  2917. 2004-04-29 Leon Woestenberg <leon.woestenberg@gmx.net>
  2918. * tcp*.c: Cleaned up source comment documentation for Doxygen processing.
  2919. * opt.h: ETHARP_ALWAYS_INSERT option removed to comply with ARP RFC.
  2920. * etharp.c: update_arp_entry() only adds new ARP entries when adviced to by
  2921. the caller. This deprecates the ETHARP_ALWAYS_INSERT overrule option.
  2922. ++ Bug fixes:
  2923. 2004-04-27 Leon Woestenberg <leon.woestenberg@gmx.net>
  2924. * etharp.c: Applied patch of bug #8708 by Toni Mountifield with a solution
  2925. suggested by Timmy Brolin. Fix for 32-bit processors that cannot access
  2926. non-aligned 32-bit words, such as soms 32-bit TCP/IP header fields. Fix
  2927. is to prefix the 14-bit Ethernet headers with two padding bytes.
  2928. 2004-04-23 Leon Woestenberg <leon.woestenberg@gmx.net>
  2929. * ip_addr.c: Fix in the ip_addr_isbroadcast() check.
  2930. * etharp.c: Fixed the case where the packet that initiates the ARP request
  2931. is not queued, and gets lost. Fixed the case where the packets destination
  2932. address is already known; we now always queue the packet and perform an ARP
  2933. request.
  2934. (STABLE-0_7_0)
  2935. ++ Bug fixes:
  2936. * Fixed TCP bug for SYN_SENT to ESTABLISHED state transition.
  2937. * Fixed TCP bug in dequeueing of FIN from out of order segment queue.
  2938. * Fixed two possible NULL references in rare cases.
  2939. (STABLE-0_6_6)
  2940. ++ Bug fixes:
  2941. * Fixed DHCP which did not include the IP address in DECLINE messages.
  2942. ++ Changes:
  2943. * etharp.c has been hauled over a bit.
  2944. (STABLE-0_6_5)
  2945. ++ Bug fixes:
  2946. * Fixed TCP bug induced by bad window resizing with unidirectional TCP traffic.
  2947. * Packets sent from ARP queue had invalid source hardware address.
  2948. ++ Changes:
  2949. * Pass-by ARP requests do now update the cache.
  2950. ++ New features:
  2951. * No longer dependent on ctype.h.
  2952. * New socket options.
  2953. * Raw IP pcb support.
  2954. (STABLE-0_6_4)
  2955. ++ Bug fixes:
  2956. * Some debug formatters and casts fixed.
  2957. * Numereous fixes in PPP.
  2958. ++ Changes:
  2959. * DEBUGF now is LWIP_DEBUGF
  2960. * pbuf_dechain() has been re-enabled.
  2961. * Mentioned the changed use of CVS branches in README.
  2962. (STABLE-0_6_3)
  2963. ++ Bug fixes:
  2964. * Fixed pool pbuf memory leak in pbuf_alloc().
  2965. Occured if not enough PBUF_POOL pbufs for a packet pbuf chain.
  2966. Reported by Savin Zlobec.
  2967. * PBUF_POOL chains had their tot_len field not set for non-first
  2968. pbufs. Fixed in pbuf_alloc().
  2969. ++ New features:
  2970. * Added PPP stack contributed by Marc Boucher
  2971. ++ Changes:
  2972. * Now drops short packets for ICMP/UDP/TCP protocols. More robust.
  2973. * ARP queueuing now queues the latest packet instead of the first.
  2974. This is the RFC recommended behaviour, but can be overridden in
  2975. lwipopts.h.
  2976. (0.6.2)
  2977. ++ Bugfixes:
  2978. * TCP has been fixed to deal with the new use of the pbuf->ref
  2979. counter.
  2980. * DHCP dhcp_inform() crash bug fixed.
  2981. ++ Changes:
  2982. * Removed pbuf_pool_free_cache and pbuf_pool_alloc_cache. Also removed
  2983. pbuf_refresh(). This has sped up pbuf pool operations considerably.
  2984. Implemented by David Haas.
  2985. (0.6.1)
  2986. ++ New features:
  2987. * The packet buffer implementation has been enhanced to support
  2988. zero-copy and copy-on-demand for packet buffers which have their
  2989. payloads in application-managed memory.
  2990. Implemented by David Haas.
  2991. Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
  2992. if an outgoing packet can be directly sent on the link, or perform
  2993. a copy-on-demand when necessary.
  2994. The application can safely assume the packet is sent, and the RAM
  2995. is available to the application directly after calling udp_send()
  2996. or similar function.
  2997. ++ Bugfixes:
  2998. * ARP_QUEUEING should now correctly work for all cases, including
  2999. PBUF_REF.
  3000. Implemented by Leon Woestenberg.
  3001. ++ Changes:
  3002. * IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
  3003. to a '0.0.0.0' IP address.
  3004. * The packet buffer implementation is changed. The pbuf->ref counter
  3005. meaning has changed, and several pbuf functions have been
  3006. adapted accordingly.
  3007. * netif drivers have to be changed to set the hardware address length field
  3008. that must be initialized correctly by the driver (hint: 6 for Ethernet MAC).
  3009. See the contrib/ports/c16x cs8900 driver as a driver example.
  3010. * netif's have a dhcp field that must be initialized to NULL by the driver.
  3011. See the contrib/ports/c16x cs8900 driver as a driver example.
  3012. (0.5.x) This file has been unmaintained up to 0.6.1. All changes are
  3013. logged in CVS but have not been explained here.
  3014. (0.5.3) Changes since version 0.5.2
  3015. ++ Bugfixes:
  3016. * memp_malloc(MEMP_API_MSG) could fail with multiple application
  3017. threads because it wasn't protected by semaphores.
  3018. ++ Other changes:
  3019. * struct ip_addr now packed.
  3020. * The name of the time variable in arp.c has been changed to ctime
  3021. to avoid conflicts with the time() function.
  3022. (0.5.2) Changes since version 0.5.1
  3023. ++ New features:
  3024. * A new TCP function, tcp_tmr(), now handles both TCP timers.
  3025. ++ Bugfixes:
  3026. * A bug in tcp_parseopt() could cause the stack to hang because of a
  3027. malformed TCP option.
  3028. * The address of new connections in the accept() function in the BSD
  3029. socket library was not handled correctly.
  3030. * pbuf_dechain() did not update the ->tot_len field of the tail.
  3031. * Aborted TCP connections were not handled correctly in all
  3032. situations.
  3033. ++ Other changes:
  3034. * All protocol header structs are now packed.
  3035. * The ->len field in the tcp_seg structure now counts the actual
  3036. amount of data, and does not add one for SYN and FIN segments.
  3037. (0.5.1) Changes since version 0.5.0
  3038. ++ New features:
  3039. * Possible to run as a user process under Linux.
  3040. * Preliminary support for cross platform packed structs.
  3041. * ARP timer now implemented.
  3042. ++ Bugfixes:
  3043. * TCP output queue length was badly initialized when opening
  3044. connections.
  3045. * TCP delayed ACKs were not sent correctly.
  3046. * Explicit initialization of BSS segment variables.
  3047. * read() in BSD socket library could drop data.
  3048. * Problems with memory alignment.
  3049. * Situations when all TCP buffers were used could lead to
  3050. starvation.
  3051. * TCP MSS option wasn't parsed correctly.
  3052. * Problems with UDP checksum calculation.
  3053. * IP multicast address tests had endianess problems.
  3054. * ARP requests had wrong destination hardware address.
  3055. ++ Other changes:
  3056. * struct eth_addr changed from u16_t[3] array to u8_t[6].
  3057. * A ->linkoutput() member was added to struct netif.
  3058. * TCP and UDP ->dest_* struct members where changed to ->remote_*.
  3059. * ntoh* macros are now null definitions for big endian CPUs.
  3060. (0.5.0) Changes since version 0.4.2
  3061. ++ New features:
  3062. * Redesigned operating system emulation layer to make porting easier.
  3063. * Better control over TCP output buffers.
  3064. * Documenation added.
  3065. ++ Bugfixes:
  3066. * Locking issues in buffer management.
  3067. * Bugfixes in the sequential API.
  3068. * IP forwarding could cause memory leakage. This has been fixed.
  3069. ++ Other changes:
  3070. * Directory structure somewhat changed; the core/ tree has been
  3071. collapsed.
  3072. (0.4.2) Changes since version 0.4.1
  3073. ++ New features:
  3074. * Experimental ARP implementation added.
  3075. * Skeleton Ethernet driver added.
  3076. * Experimental BSD socket API library added.
  3077. ++ Bugfixes:
  3078. * In very intense situations, memory leakage could occur. This has
  3079. been fixed.
  3080. ++ Other changes:
  3081. * Variables named "data" and "code" have been renamed in order to
  3082. avoid name conflicts in certain compilers.
  3083. * Variable++ have in appliciable cases been translated to ++variable
  3084. since some compilers generate better code in the latter case.
  3085. (0.4.1) Changes since version 0.4
  3086. ++ New features:
  3087. * TCP: Connection attempts time out earlier than data
  3088. transmissions. Nagle algorithm implemented. Push flag set on the
  3089. last segment in a burst.
  3090. * UDP: experimental support for UDP-Lite extensions.
  3091. ++ Bugfixes:
  3092. * TCP: out of order segments were in some cases handled incorrectly,
  3093. and this has now been fixed. Delayed acknowledgements was broken
  3094. in 0.4, has now been fixed. Binding to an address that is in use
  3095. now results in an error. Reset connections sometimes hung an
  3096. application; this has been fixed.
  3097. * Checksum calculation sometimes failed for chained pbufs with odd
  3098. lengths. This has been fixed.
  3099. * API: a lot of bug fixes in the API. The UDP API has been improved
  3100. and tested. Error reporting and handling has been
  3101. improved. Logical flaws and race conditions for incoming TCP
  3102. connections has been found and removed.
  3103. * Memory manager: alignment issues. Reallocating memory sometimes
  3104. failed, this has been fixed.
  3105. * Generic library: bcopy was flawed and has been fixed.
  3106. ++ Other changes:
  3107. * API: all datatypes has been changed from generic ones such as
  3108. ints, to specified ones such as u16_t. Functions that return
  3109. errors now have the correct type (err_t).
  3110. * General: A lot of code cleaned up and debugging code removed. Many
  3111. portability issues have been fixed.
  3112. * The license was changed; the advertising clause was removed.
  3113. * C64 port added.
  3114. * Thanks: Huge thanks go to Dagan Galarneau, Horst Garnetzke, Petri
  3115. Kosunen, Mikael Caleres, and Frits Wilmink for reporting and
  3116. fixing bugs!
  3117. (0.4) Changes since version 0.3.1
  3118. * Memory management has been radically changed; instead of
  3119. allocating memory from a shared heap, memory for objects that are
  3120. rapidly allocated and deallocated is now kept in pools. Allocation
  3121. and deallocation from those memory pools is very fast. The shared
  3122. heap is still present but is used less frequently.
  3123. * The memory, memory pool, and packet buffer subsystems now support
  3124. 4-, 2-, or 1-byte alignment.
  3125. * "Out of memory" situations are handled in a more robust way.
  3126. * Stack usage has been reduced.
  3127. * Easier configuration of lwIP parameters such as memory usage,
  3128. TTLs, statistics gathering, etc. All configuration parameters are
  3129. now kept in a single header file "lwipopts.h".
  3130. * The directory structure has been changed slightly so that all
  3131. architecture specific files are kept under the src/arch
  3132. hierarchy.
  3133. * Error propagation has been improved, both in the protocol modules
  3134. and in the API.
  3135. * The code for the RTXC architecture has been implemented, tested
  3136. and put to use.
  3137. * Bugs have been found and corrected in the TCP, UDP, IP, API, and
  3138. the Internet checksum modules.
  3139. * Bugs related to porting between a 32-bit and a 16-bit architecture
  3140. have been found and corrected.
  3141. * The license has been changed slightly to conform more with the
  3142. original BSD license, including the advertisement clause.
  3143. (0.3.1) Changes since version 0.3
  3144. * Fix of a fatal bug in the buffer management. Pbufs with allocated
  3145. RAM never returned the RAM when the pbuf was deallocated.
  3146. * TCP congestion control, window updates and retransmissions did not
  3147. work correctly. This has now been fixed.
  3148. * Bugfixes in the API.
  3149. (0.3) Changes since version 0.2
  3150. * New and improved directory structure. All include files are now
  3151. kept in a dedicated include/ directory.
  3152. * The API now has proper error handling. A new function,
  3153. netconn_err(), now returns an error code for the connection in
  3154. case of errors.
  3155. * Improvements in the memory management subsystem. The system now
  3156. keeps a pointer to the lowest free memory block. A new function,
  3157. mem_malloc2() tries to allocate memory once, and if it fails tries
  3158. to free some memory and retry the allocation.
  3159. * Much testing has been done with limited memory
  3160. configurations. lwIP now does a better job when overloaded.
  3161. * Some bugfixes and improvements to the buffer (pbuf) subsystem.
  3162. * Many bugfixes in the TCP code:
  3163. - Fixed a bug in tcp_close().
  3164. - The TCP receive window was incorrectly closed when out of
  3165. sequence segments was received. This has been fixed.
  3166. - Connections are now timed-out of the FIN-WAIT-2 state.
  3167. - The initial congestion window could in some cases be too
  3168. large. This has been fixed.
  3169. - The retransmission queue could in some cases be screwed up. This
  3170. has been fixed.
  3171. - TCP RST flag now handled correctly.
  3172. - Out of sequence data was in some cases never delivered to the
  3173. application. This has been fixed.
  3174. - Retransmitted segments now contain the correct acknowledgment
  3175. number and advertised window.
  3176. - TCP retransmission timeout backoffs are not correctly computed
  3177. (ala BSD). After a number of retransmissions, TCP now gives up
  3178. the connection.
  3179. * TCP connections now are kept on three lists, one for active
  3180. connections, one for listening connections, and one for
  3181. connections that are in TIME-WAIT. This greatly speeds up the fast
  3182. timeout processing for sending delayed ACKs.
  3183. * TCP now provides proper feedback to the application when a
  3184. connection has been successfully set up.
  3185. * More comments have been added to the code. The code has also been
  3186. somewhat cleaned up.
  3187. (0.2) Initial public release.
