goldsimon	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	1b07fecbf3	Introduced ETHARP_STATS	2007-11-28 21:25:06 +00:00
goldsimon	f07c1cf874	fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by letting ip_route only use netifs that are up.	2007-11-28 06:48:50 +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
goldsimon	f57c2424cf	Fixed bug #21582: pcb->acked accounting can be wrong when ACKs arrive out-of-order	2007-11-26 19:08:39 +00:00
goldsimon	1b208d0954	dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy algorithm; corrected some assert messages	2007-11-25 11:51:44 +00:00
goldsimon	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
goldsimon	9dd4ad6c1f	Added thread-safe function gethostbyname_r (as in glibc)	2007-11-18 16:36:34 +00:00
goldsimon	1faf0ab9e3	Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into inet and chksum part; changed includes in all lwIP files as appropriate	2007-11-16 19:31:10 +00:00
goldsimon	e6ec23d7cc	Added sequential (socket API) function gethostbyname and the struct hostent it uses	2007-11-16 17:29:30 +00:00
goldsimon	e2cd201f6a	Added sequential dns resolver function for netconn api (netconn_gethostbyname)	2007-11-16 17:16:17 +00:00
fbernon	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
fbernon	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
goldsimon	21bbc9a81a	Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can happen any time). Now the packet simply isn't enqueued when out of memory.	2007-11-10 17:41:46 +00:00
goldsimon	bfe24b138d	Patch #6215: added ifAdminStatus write support (if explicitly enabled by defining SNMP_SAFE_REQUESTS to 0); added code to check link status for ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.	2007-11-06 20:53:37 +00:00
goldsimon	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
goldsimon	2d5908f4de	Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or TCP_MSS if that is smaller) as long as no MSS option is received from the remote host.	2007-11-01 16:53:43 +00:00
goldsimon	298d5cf042	Fixed bug #21491: The MSS option sent (with SYN) is now based on TCP_MSS instead of pcb->mss (on passive open now effectively sending our configured TCP_MSS instead of the one received).	2007-11-01 16:23:32 +00:00
goldsimon	853765954e	Fixed bug #21181: On active open, the initial congestion window was calculated based on the configured TCP_MSS, not on the MSS option received with SYN+ACK.	2007-11-01 15:51:43 +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	199648ff37	Changed initialization: many init functions are not needed any more since we now rely on the compiler initializing global and static variables to zero!	2007-10-09 19:59:56 +00:00
goldsimon	536f2e42d2	Fixed UDPLite receive: checksum was calculated wrong if checksum coverage != tot_len	2007-10-09 19:43:29 +00:00
goldsimon	9ef005454a	lfree was not updated in mem_realloc!	2007-10-08 18:39:44 +00:00
goldsimon	2ca113a218	Fixed UDPLite SENDING: Checksum was always generated too short and also was generated wrong if checksum coverage != tot_len.	2007-10-07 20:19:23 +00:00
fbernon	9804b25acc	Fix CHANGELOG entry	2007-10-07 17:30:50 +00:00
fbernon	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
goldsimon	b7ef6077df	Changed IP_REASSEMBLY to enqueue the received pbufs so that multiple packets can be reassembled simultaneously and no static reassembly buffer is needed.	2007-10-06 15:24:43 +00:00
goldsimon	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
goldsimon	0aa3d89134	Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state) by checking tcp_tw_pcbs also	2007-09-20 18:27:50 +00:00
kleshov	4ffafdeb86	Fixed bug #21077: inaccuracy in calculation of lwip_stat.mem.used	2007-09-19 17:56:39 +00:00
goldsimon	0bf32b957d	Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies)	2007-09-19 06:12:34 +00:00
fbernon	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	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
fbernon	939180c1a1	igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with IGMP, and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags if you want IGMP on an interface. igmp_stop() is now called inside netif_remove(). igmp_report_groups() is now called inside netif_set_link_up() (need to have LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up (avoid to wait the next query message to receive the matching multicast streams).	2007-09-09 20:46:33 +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
fbernon	ac1149156d	several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or simply remove it as long as "lwip/opt.h" is included before (this one include "lwip/debug.h" which already include "lwip/arch.h"). Like that, default defines are provided by "lwip/arch.h" if they are not defined in cc.h, in the same spirit than "lwip/opt.h" for lwipopts.h.	2007-09-06 16:43:43 +00:00
fbernon	ca866c0d7d	Integrate "task #7272 : LWIP_ICMP option". The new option LWIP_ICMP enable/disable ICMP module inside the IP stack (enable per default). Be careful, disabling ICMP make your product non-compliant to RFC1122, but help to reduce footprint, and to reduce "visibility" on the Internet.	2007-09-05 17:20:45 +00:00
fbernon	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	c1f89c5640	Move some build time checkings inside init.c for task #7142 "Sanity check user-configurable values".	2007-09-05 13:19:25 +00:00
fbernon	d4616a7fc6	Replace mem_malloc call by memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the value). It will avoid potential fragmentation problems, use a counter to know how many times a group is used on an netif, and free it when all applications leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity check if LWIP_IGMP!=0).	2007-09-04 15:15:20 +00:00
