7fa9010f35 igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have some problems to fill the IP header on some targets, use now the ip.h macros to do it). 2008-03-17 13:40:00 +00:00

e07d71f5e8 sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using (lwip_)recvfrom with valid "from" and "fromlen" parameters, on a TCP connection caused a crash. Note that using (lwip_)recvfrom like this is a bit slow and that using (lwip)getpeername is the good lwip way to do it (so, using recv is faster on tcp sockets). 2008-03-13 20:03:57 +00:00

9906e4c984 api_msg.c, opt.h: replace DEFAULT_RECVMBOX_SIZE per DEFAULT_TCP_RECVMBOX_SIZE, DEFAULT_UDP_RECVMBOX_SIZE and DEFAULT_RAW_RECVMBOX_SIZE (to optimize queues sizes), like suggested for the task #7490 "Add return value to sys_mbox_post". 2008-01-11 23:50:10 +00:00
fbernon
4e40fee1db tcpip.h, tcpip.c: add tcpip_callback_with_block function for the task #7490 "Add return value to sys_mbox_post". tcpip_callback is always defined as "blocking" ("block" parameter = 1). 2008-01-10 21:47:52 +00:00

5941b3c86e sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h, opt.h: Introduce changes for task #7490 "Add return value to sys_mbox_post" with some modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which indicate the number of pointers query by the mailbox. There is three defines in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the netconn::acceptmbox. Port maintainers, you can decide to just add this new parameter in your implementation, but to ignore it to keep the previous behavior. The new sys_mbox_trypost function return a value to know if the mailbox is full or if the message is posted. Take a look to sys_arch.txt for more details. This new function is used in tcpip_input (so, can be called in an interrupt context since the function is not blocking), and in recv_udp and recv_raw. 2008-01-05 21:10:32 +00:00

2b54da5070 api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum dns_result" by err_t type. Add a new err_t code "ERR_INPROGRESS". 2007-12-13 23:06:49 +00:00
fbernon
de11e7fd75 dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles are the ones which have ram usage. 2007-12-12 17:56:03 +00:00
fbernon
ac10470643 netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static set of variables (=0) or a local one (=1). In this last case, your port should provide a function "struct hostent* sys_thread_hostent( struct hostent* h)" which have to do a copy of "h" and return a pointer ont the "per-thread" copy. 2007-12-05 23:00:02 +00:00
goldsimon
8d3d08e814 fix bug #21699 (segment leak in ooseq): add assert that all segment lists are empty in tcp_pcb_remove before setting pcb to CLOSED state; don't directly set CLOSED state from LAST_ACK in tcp_process 2007-12-04 20:41:12 +00:00

f3f7bd00e5 ip_input: check if a packet is for inp first before checking all other netifs on netif_list (speeds up packet receiving in most cases) 2007-12-03 17:55:01 +00:00
goldsimon
47d8d69b81 fix bug #21654: exclude definition of struct timeval from #ifndef FD_SET. If including <sys/time.h> for system-struct timeval, LWIP_TIMEVAL_PRIVATE now has to be set to 0 in lwipopts.h 2007-12-02 15:24:02 +00:00
goldsimon
113a52d091 fix bug #21656 (recvmbox problem in netconn API): always allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox. This is a fix for thread-safety and allocates all items needed for a netconn when the netconn is created. 2007-12-02 14:53:50 +00:00

b28cd02149 task #7497: Sort lists (pcb, netif, ...) for faster access UDP: move a (connected) pcb selected for input to the front of the list of pcbs so that it is found faster next time. Same for RAW pcbs that have eaten a packet. 2007-11-30 09:44:18 +00:00
goldsimon
cedd5c21e6 first attempt to fix bug #21655 (DHCP doesn't work reliably with multiple netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed to netif->dhcp->pcb only (if that exists) and not to any other pcb for the same port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address) 2007-11-30 08:55:15 +00:00

goldsimon
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
goldsimon
b4741332e0 Implemented new function udp_sendto_if which takes the netif to send as an argument (to be able to send on netifs that are down). 2007-11-27 20:13:16 +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
95425552d7 Implemented calculating the effective send-mss based on the MTU of the netif used to send. Enabled by default. Disable by setting LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21535. 2007-11-21 18:37:23 +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).

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

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

47ae677652 enable to remove SNMP timer (which consumne several cycles even when it's not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime() each 10ms (but, it's intrusive if you use sys_timeout feature). Now, you can decide to call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime() or snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro. This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only when it's queried (any direct call to "sysuptime" is changed by a call to snmp_get_sysuptime). 2007-09-10 18:50:44 +00:00

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

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

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

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

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

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

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

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

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

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

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
