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

8020ba2dc5 tcp_send_ctrl(): call tcp_enqueue with the new flag TCP_WRITE_FLAG_COPY instead of 1 2007-11-12 19:38:25 +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

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

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

6d9b44e243 IP_REASSEMBLY: send ICMP time exceeded when discarding datagrams for which the first fragment was received; try to keep the header of the first (octet 0) fragment; combined code to make it smaller; fixed bug in timer: when freeing packets, counter was not updated correctly 2007-10-15 19:33:16 +00:00

goldsimon
c41508cc8d Added check that MEMP_NUM_REASSDATA is bigger than IP_REASS_MAX_PBUFS (because each MEMP_NUM_REASSDATA has one pbuf at least!) 2007-10-11 19:26:04 +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

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

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

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

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

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

79b0484e20 Minor changes (fix some warnings like "function declaration isn't a prototype" and "no previous prototype for 'lwip_init'"...) 2007-09-04 13:51:48 +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

327f06bbaf Replace "netif_default = NULL;" by "netif_set_default(NULL);" in netif_remove (do some processing, like for SNMP...) 2007-09-03 12:22:00 +00:00

fca25479ad Minor fix (else, cause build error). Since SO_REUSE is always used in the code (even if the current code is not working), it is defined in opt.h with 0 as default value (it's normal). So, the error is not if it is defined, but if it is defined to 1. 2007-08-31 09:42:32 +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
