6746beb2a3 Compacted code: moved the code creating a netconn (without pcb) from netconn_new_with_proto_and_callback to new (synchroneous) function netconn_alloc_with_proto_and_callback and call this function from netconn_new_with_proto_and_callback and accept_function. 2007-11-30 12:54:10 +00:00

03777ccb21 Changed error handling: ERR_MEM, ERR_BUF and ERR_RTE are seen as non-fatal, all other errors are fatal. netconns and sockets block most operations once they have seen a fatal error. 2007-11-27 21:15:44 +00:00

c86b446d4c Moved lwip_gethostbyname from sockets.c to the new file netdb.c; included lwip_getaddrinfo. 2007-11-24 16:12:02 +00:00
goldsimon
dc515c7ad3 Fixed bug #20287: tcp_output_nagle sends too early. This fixes the nagle algorithm; nagle now also works for all raw API applications and has to be explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY' 2007-11-21 17:59:03 +00:00

fbernon
f58515b51e api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if name received match the name query), implement DNS_USES_STATIC_BUF (the place where copy dns payload to parse the response), return an error if there is no place for a new query, and fix some minor problems. 2007-11-19 22:42:01 +00:00

0c0e8d6544 opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple name requests with RAW api interface. Initialization is done in lwip_init() with build time options. DNS timer is added in tcpip_thread context. DHCP can set DNS server ip addresses when options are received. You need to set LWIP_DNS=1 in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set to get some traces with LWIP_DEBUGF. Sanity check have been added. There is a "todo" list with points to improve. 2007-11-14 23:27:13 +00:00

a4d14722f3 sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now, most of the netconn_peer and netconn_addr processing is done inside tcpip_thread context in do_getaddr. 2007-11-12 22:39:24 +00:00

f3dbd986cb Task #7410: Removed the need to include core header files in api.h (ip/tcp/udp/raw.h) to hide the internal implementation from netconn api applications. 2007-11-06 20:31:28 +00:00
fbernon
ecce865cfe api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for UDP & RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled by default). Netconn API users can use the netconn_recv_bufsize macro to access it. This is a first release which have to be improve for TCP. Note it used the netconn::recv_avail which need to be more "thread-safe" (note there is already the problem for FIONREAD with lwip_ioctl/ioctlsocket). 2007-11-02 10:37:08 +00:00
fbernon
cbe9b050a9 sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h, tcp_out.c: Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used at socket api layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE at raw api layer. This option enable to delayed TCP PUSH flag on multiple "write" calls. Note that previous "copy" parameter for "write" APIs is now called "apiflags". 2007-11-01 17:37:50 +00:00
fbernon
7077d51f1f api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than TCP_EVENT_xxx macros to get a code more readable. It could also help to remove some code (like we have talk in "patch #5919 : Create compile switch to remove select code"), but it could be done later. 2007-10-24 12:09:18 +00:00
goldsimon
270c7c1110 Removed check for conn->err for functions whose counterparts in api_msg.c also do the check (1. remove redundant code, 2. check is better done in tcpip thread context) 2007-10-22 20:01:16 +00:00

87e16a8f47 sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT: this change cause an API breakage for netconn_peer, since a parameter type change. Any compiler should cause an error without any changes in yours netconn_peer calls (so, it can't be a "silent change"). It also reduce a little bit the footprint for socket layer (lwip_getpeername & lwip_getsockname use now a common lwip_getaddrname function since netconn_peer & netconn_addr have the same parameters). 2007-10-07 17:26:54 +00:00

cb71d6d393 Moved ethernet_input from tcpip.c to etharp.c so all netifs (or ports) can use it. 2007-10-05 14:00:48 +00:00
fbernon
79c00be516 netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change the common function to reduce a little bit the footprint (for all functions using only the "netif" parameter). 2007-10-05 13:34:48 +00:00
fbernon
949efb414a netifapi.h, netifapi.c: add functions netifapi_netif_set_up, netifapi_netif_set_down, netifapi_autoip_start and netifapi_autoip_stop. Use a common function to reduce a little bit the footprint (for all functions using only the "netif" parameter). 2007-10-03 16:54:27 +00:00

2bdd916b06 udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add IP_MULTICAST_IF option in socket API, and a new field "multicast_ip" in "struct udp_pcb" (for netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt processing for IP_MULTICAST_TTL and IP_MULTICAST_IF. 2007-09-15 15:19:41 +00:00

fbernon
8205737fdb sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change). Use this new field to access to common pcb fields (ttl, tos, so_options, etc...). Enable to access to these fields with LWIP_TCP=0. 2007-09-07 23:47:02 +00:00
fbernon
e3cd1ac1f9 Minor changes (but in lot of files): add #if/#endif for options where they could miss. #if LWIP_xxx if always put after #include "lwip/opt.h" (note this one indirectly include cc.h). Move others includes inside #if/#endif block. 2007-09-07 23:01:59 +00:00

90a3f88c08 Change parameters list for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new parameters have to be provided: a task name, and a task stack size. For this one, since it's platform dependant, you could define the best one for you in your lwipopts.h. For port maintainers, you can just add these new parameters in your sys_arch.c file, and but it's not mandatory, use them in your OS specific functions. 2007-09-05 16:14:28 +00:00
fbernon
62b4741b19 Changes for "#20503 IGMP Improvement". Initialize igmp_mac_filter to NULL in netif_add (this field should be set in the netif's "init" function). Use the "imr_interface" field (for socket layer) and/or the "interface" field (for netconn layer), for join/leave operations. The igmp_join/leavegroup first parameter change from a netif to an ipaddr. This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany). 2007-09-03 14:53:18 +00:00

245bce04d1 Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf functions from api/api_lib". Now netbuf API is independant of netconn, and can be used with other API (application based on raw API, or future "socket2" API). Ports maintainers just have to add src/api/netbuf.c in their makefile/projects. 2007-08-30 16:55:10 +00:00
fbernon
cd208314e0 igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add igmp_start. igmp_start is call inside netif_add. Now, igmp initialization is in the same spirit than the others modules. Modify some IGMP debug traces. 2007-08-29 21:12:32 +00:00

48db3a3e92 Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init function" Add lwip_init function to regroup all modules initializations, and to provide a place to add code for task #7142 "Sanity check user-configurable values". Ports maintainers should remove direct initializations calls from their code, and add init.c in their makefiles. Note that lwip_init() function is called inside tcpip_init, but can also be used by raw api users since all calls are disabled when matching options are disabled. Also note that their is new options in opt.h, you should configure in your lwipopts.h (they are enabled per default). 2007-08-29 08:11:06 +00:00

7182fb8fb0 tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for any kind of packets. These packets are considered like Ethernet packets (payload pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag. Else, packets are considered like IP packets (payload pointing to iphdr). 2007-08-29 07:51:20 +00:00

54c1025ec0 First fix for "bug #20900 : Potential crash error problem with netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state and remove obsolete ones (NETCONN_RECV & NETCONN_ACCEPT). 2007-08-27 10:08:53 +00:00
marcbou
180e6d2c75 Reset the callbacks and arg (conn) to NULL in do_close_internal(), because 
TCP callbacks in api_msg.c can under certain circumstances be called with an
invalid conn pointer after the connection has been closed (and conn has been
freed).
 2007-08-26 23:58:33 +00:00

42f3c24fc4 tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT & ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the name is tcpip_input (we keep the name of 1.2.0 function). 2007-08-22 10:04:35 +00:00

goldsimon
eb875de67e Added assertions where PBUF_RAM pbufs are used and an assumption is made that this pbuf is in one piece (i.e. not chained). These assumptions clash with the possibility of converting to fully pool-based pbuf implementations, where PBUF_RAM pbufs might be chained. 2007-07-03 20:28:35 +00:00
