jgrubb	05e177e2c8	+bug fix #20478: memp_malloc now returns NULL for failed allocation (instead of NULL+MEMP_SIZE)	2007-07-14 00:21:37 +00:00
fbernon	116bcb9dfb	opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to add a link callback in the netif struct, and functions to handle it. Be carefull for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in ethernetif.c) if you want to be sure to be compatible with future changes...	2007-07-13 15:00:40 +00:00
fbernon	6a452951f5	api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free in all error cases.	2007-07-13 14:28:15 +00:00
fbernon	a891854ef5	Fix bug #20315: possible memory leak problem if tcp_listen failed, because current code doesn't follow rawapi.txt documentation.	2007-07-13 13:59:11 +00:00
kieranm	4ac0580aa0	2007-07-13 Kieran Mansley ... * src/core/tcp_in.c Apply patch#5741 from Oleg Tyshev to fix bug in out of sequence processing of received packets	2007-07-13 12:24:32 +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
goldsimon	9a4a5b1816	Final fix for bug #20021 and some other problems when closing tcp netconns: removed conn->sem, less context switches when closing, both netconn_close and netconn_delete should safely close tcp connections.	2007-07-03 19:29:59 +00:00
goldsimon	96e4ec4a15	Added option LWIP_NETIF_HWADDRHINT (default=off) to cache ARP table indices with each pcb instead of single-entry cache for the complete stack.	2007-07-02 20:41:22 +00:00
goldsimon	fa4b711495	Added some ASSERTS and casts to prevent warnings when assigning to smaller types.	2007-07-02 20:13:45 +00:00
fbernon	b6750de9e8	sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.	2007-06-30 13:24:11 +00:00
goldsimon	6c3c184bc7	Added check to prevent tcp_pcb->snd_queuelen from overflowing.	2007-06-29 17:09:47 +00:00
goldsimon	24e29cecae	Fixed bug #20287: Fixed nagle algorithm (sending was done too early if a segment contained chained pbufs)	2007-06-28 20:05:38 +00:00
fbernon	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
fbernon	d6fbe45296	netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the option LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last modifications in api_lib/api_msg (use pointers and not type with table, etc...)	2007-06-28 10:11:05 +00:00
goldsimon	2270f0d172	Fixed bug #20259: struct udp_hdr was lacking the packin defines.	2007-06-26 07:32:17 +00:00
goldsimon	dcc2247a90	Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload for udp packets with no matching pcb.	2007-06-25 17:30:16 +00:00
goldsimon	00b7aeb49b	Fixed bug #20220: UDP PCB search in udp_input(): a non-local match could get udp input packets if the remote side matched.	2007-06-25 17:24:31 +00:00
goldsimon	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
goldsimon	ea7b0052f3	Implemented socket options SO_NO_CHECK for UDP sockets to disable UDP checksum generation on transmit.	2007-06-17 11:46:30 +00:00
goldsimon	cbf281589b	Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get changed in netif_set_ipaddr if previous netif->ip_addr.addr was 0.	2007-06-16 13:32:10 +00:00
goldsimon	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
goldsimon	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
fbernon	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
fbernon	e01f342048	Contrib module by Dominik Spies: autoip.h, autoip.c, dhcp.h, dhcp.c, netif.h, netif.c, etharp.h, etharp.c, opt.h: AutoIP implementation available for IPv4, with new options LWIP_AUTOIP and LWIP_DHCP_AUTOIP_COOP if you want to cooperate with DHCP. Some tips to adapt (see TODO mark in the source code).	2007-06-09 16:57:04 +00:00
goldsimon	c028619cdd	Modified order of parameters for etharp_output() to match netif->output so etharp_output() can be used directly as netif->output to save one function call.	2007-06-08 22:20:05 +00:00
goldsimon	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
goldsimon	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
goldsimon	add68e0da1	Checked in patch #5914: Moved sockopt processing into tcpip_thread.	2007-06-01 17:15:54 +00:00
fbernon	0a4130a4ff	Minor, fix files modified by last patch...	2007-05-23 19:49:55 +00:00
fbernon	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
