ab4c3a326f autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which compute a "pseudo-random" value based on netif's MAC and some autoip fields. It's always possible to define this macro in your own lwipopts.h to always use C library's rand(). Note that autoip_create_rand_addr doesn't use this macro. 2007-06-28 18:05:38 +00:00

b51d1b79a3 Combined etharp_request with etharp_raw for both LWIP_AUTOIP =0 and =1 to remove redundant code. 2007-06-24 12:51:22 +00:00
goldsimon
0c18e653e8 Introduced the option MEM_USE_POOLS to use 4 pools with different sized elements instead of a heap. This both prevents memory fragmentation and gives a higher speed at the cost of more memory consumption. Turned off by default. 2007-06-21 20:12:11 +00:00
goldsimon
f49fc35f55 Converted the length argument of netconn_write (and therefore also api_msg_msg.msg.w.len) from u16_t into int to be able to send a bigger buffer than 64K with one time (mainly used from lwip_send). 2007-06-21 19:32:26 +00:00
goldsimon
2aef8bad55 Moved the nagle algorithm from netconn_write/do_write into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too. 2007-06-21 18:55:09 +00:00
goldsimon
9f05cabf87 Fixed bug #20021: Moved sendbuf-processing in netconn_write from api_lib.c to api_msg.c to also prevent multiple context-changes on low memory or empty send-buffer. 2007-06-21 18:40:21 +00:00
goldsimon
d3f0a3211d Changed etharp to use a defined hardware address length of 6 to avoid loading netif->hwaddr_len every time (since this file is only used for ethernet and struct eth_addr already had a defined length of 6). 2007-06-19 16:22:55 +00:00

15e8208457 pcb_new sets conn->err if protocol is not implemented -> netconn_new_..() does not allocate a new connection for unsupported protocols. 2007-06-13 19:00:21 +00:00
fbernon
d8fe18c28e api_lib.c: change return expression in netconn_addr and netconn_peer, because conn->err was reset to ERR_OK without any reasons (and error was lost)... 2007-06-13 18:08:49 +00:00
fbernon
9ee85fb1b6 debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like invalid pointers or parameters, and let the possibility to redefined it in cc.h. Use this macro to check "conn" parameter in api_msg.c functions (some others change will be done...). 2007-06-13 18:00:54 +00:00
fbernon
bdbc96f453 opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162. Rename MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to avoid some macro names collision with some OS macros. 2007-06-13 17:17:26 +00:00

046a270156 Added UDP lite support for sockets 2007-06-11 18:43:16 +00:00
goldsimon
2f293d53ba UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0, create checksum over the complete packet. On RX, if it's < 8 (and not 0), discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both UDP & UDP Lite. 2007-06-11 18:03:57 +00:00

1d7caed340 tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP flags" where TCP flags wasn't initialized in tcp_keepalive. Reported by Srinivas Gollakota with help of Oleg Tyshev. 2007-06-11 13:59:10 +00:00
goldsimon
95f4c02381 Included switch LWIP_UDPLITE (enabled by default) to switch off UDP-Lite support if not needed (reduces udp.c code size) 2007-06-10 12:02:24 +00:00

0e9cb48ea1 Changed define NETIF_INIT_SNMP(type, speed) to include the name of the struct netif to change... 2007-06-08 19:59:20 +00:00
goldsimon
945460c67e Added define NETIF_INIT_SNMP(type, speed) to initialize per-netif snmp variables, added initialization of those to slipif and loopif. 2007-06-08 17:17:41 +00:00
goldsimon
3a607a197e opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF (defaulting to off for now) that can be set to 0 to send fragmented packets by passing PBUF_REFs down the stack. 2007-06-03 18:36:42 +00:00

974cf08e5d udp_input(): Input pbuf was not freed if pcb had no recv function registered, p->payload was modified without modifying p->len if sending icmp_dest_unreach() (had no negative effect but was definitively wrong). 2007-06-03 11:32:03 +00:00
goldsimon
7abfe74fa4 Corrected bug #19937: ICMP assumes p_buf has space for ethernet header. Allocating new pbuf if the input pbuf isn't big enough. 2007-06-03 10:48:23 +00:00

a3fdc33f88 api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP connections, such present in patch #5959. 2007-05-23 19:18:09 +00:00
fbernon
a330917ee8 api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only allocated by do_listen if success) and netconn_accept errors handling. In most of api_lib functions, we replace some errors checkings like "if (conn==NULL)" by ASSERT, except for netconn_delete. 2007-05-23 18:43:30 +00:00
fbernon
0fe5dd8d43 api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to return an error code if it's impossible to fetch a pbuf on a TCP connection (and not directly close the recvmbox). 2007-05-23 17:53:35 +00:00
fbernon
953d783a3e api.h, api_lib.c, api_msg.c, sockets.c: group the different NETCONN_UDPxxx code in only one part... 2007-05-23 17:46:53 +00:00
fbernon
2ff620e1b5 sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was only used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features like "sys_timeout" in their application threads. 2007-05-22 20:51:34 +00:00
goldsimon
0aaf69769f Fixed bug #1895 (tcp_bind not correct) by introducing a list of bound but unconnected (and non-listening) tcp_pcbs. 2007-05-22 20:48:36 +00:00
fbernon
499f4689be api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to see which parameters are used by which do_xxx function, and to avoid "misusing" parameters (patch #5938). 2007-05-22 09:54:00 +00:00
goldsimon
81ac03a28b Included patch #5938: changed raw_pcb.protocol from u16_t to u8_t since for IPv4 and IPv6, proto is only 8 bits wide. This affects the api, as there, the protocol was u16_t, too. 2007-05-22 07:31:06 +00:00
goldsimon
a4f4e6e71d Addition to patch #5913: decrease size of memp_memory.

goldsimon
2740a81103 If a udp_pcb has a local_ip set, check if it is the same as the one of the netif used for sending to prevent sending from old addresses after a netif address gets changed (partly fixes bug #3168). 2007-05-16 18:55:25 +00:00
fbernon
0f8a2d6418 tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not work with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in tcpip_init) because we have to be sure that network interfaces are already added (mac filter is updated only in igmp_init for the moment). 2007-05-16 14:12:52 +00:00

fd982597fe Removed semaphores from memp, changed sys_sem_wait calls into sys_arch_sem_wait calls to prevent timers from running while waiting for the heap. This fixes bug #19167. 2007-05-16 11:02:07 +00:00

62d705903e task #6831: removed the option PBUF_POOL_USES_MEMP and removed the old pbuf pool code, pbuf pool now always allocates from a memp pool 2007-05-13 18:17:22 +00:00
goldsimon
a5e2e9ea03 (see task #6831): Included new option PBUF_POOL_USES_MEMP to use a memp pool for PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to remove redundant code. 2007-05-13 16:16:03 +00:00

efd3104fd0 Fixed bug from patch #5865 by moving the defines for socket options (lwip_set/-getsockopt) used with level IPPROTO_TCP from tcp.h to sockets.h. 2007-05-13 14:34:02 +00:00
fbernon
9cf1390dc6 sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c, tcpip.c: Include a function pointer instead of a table index in the message to reduce footprint. Disable some part of lwip_send and lwip_sendto if some options are not set (LWIP_TCP, LWIP_UDP, LWIP_RAW). 2007-05-11 08:58:23 +00:00
goldsimon
84fc489e0c Included patch #5448: include '#ifdef __cplusplus \ extern "C" {' in all header files. Now you can write your application using the lwIP stack in C++ and simply #include the core files. Note I have left out the netif/ppp/*h header files for now, since I don't know which files are included by applications and which are for internal use only. 2007-05-10 10:59:20 +00:00
goldsimon
255d5a748f Included patch #5920: Create define to override C-library memcpy. 2 Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for situations where some compilers might inline the copy and save a function call. Also replaced all calls to memcpy() with calls to (S)MEMCPY(). 2007-05-10 05:20:05 +00:00
goldsimon
1571881f7a If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc()) to be overriden in case the C-library malloc implementation is not protected against concurrent access. 2007-05-08 11:00:49 +00:00

79d9b36ece Further update to ARP queueing: Changed pbuf_copy() implementation so that it can be reused (don't allocate the target pbuf inside pbuf_copy()). 2007-05-04 21:31:25 +00:00
goldsimon
be316e81a7 Introduced fast one-entry-cache to speed up ARP lookup when sending multiple packets to the same host. 2007-05-04 19:31:27 +00:00
goldsimon
7f232b43ff checked in patch #5913: in memp_malloc() we can return memp as mem to save a little RAM (next pointer of memp is not used while not in pool). 2007-05-04 15:52:11 +00:00

5a12aeb4a1 sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162 "lwip_sento: a possible to corrupt remote addr/port connection state". Reduce problems "not enought memory" with netbuf (if we receive lot of datagrams). Improve lwip_sendto (only one exchange between sockets api and api_msg which run in tcpip_thread context). Add netconn_sento function. WARNING, if you directly access to "fromaddr" & "fromport" field from netbuf struct, these fields are now renamed "addr" & "port". 2007-05-04 15:18:29 +00:00

02e194b15f fix bug #2595: "loopif results
in NULL reference for incoming TCP packets". Loopif has to be configured
(using LWIP_LOOPIF_MULTITHREADING) to directly call netif->input()
(multithreading environments, e.g. netif->input() = tcpip_input()) or
putting packets on a list that is fed to the stack by calling loopif_poll()
(single-thread / NO_SYS / polling environment where e.g.
netif->input() = ip_input).

3eb38d7611 api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL) calls from api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call. Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a faster and more reliable communication between api_lib and tcpip. 2007-03-21 16:38:58 +00:00

7294cb080b * Fix all uses of pbuf_header to check the return value. In some
cases just assert if it fails as I'm not sure how to fix them, but
    this is no worse than before when they would carry on regardless
    of the failure.
