d4ecb23015 raw.c, udp.c, init.c, opt.h, ip.h, sockets.h: bug #26309: Implement the SO(F)_BROADCAST filter for all API layers. Avoid the unindented reception of broadcast packets even when this option wasn't set. Port maintainers which want to enable this filter have to set IP_SOF_BROADCAST=1 in opt.h. If you want this option also filter broadcast on recv operations, you also have to set IP_SOF_BROADCAST_RECV=1 in opt.h. 2009-04-29 12:42:43 +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

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

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

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

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

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

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

118331207b udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a multicast packet on a udp pcb binded on an netif's IP address, and not on "any". 2007-08-09 18:34:03 +00:00

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

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

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

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

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

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

5368a760cf most of files: prefix all debug.h define with "LWIP_" to avoid any conflict with others environment defines (these were too "generic"). 2007-03-30 08:47:04 +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.

6158aa684b udp_input() operated by removing the IP and UDP headers, putting back
the UDP header, then re-removing it.  However, pbuf_header() can't add
back the UDP header on pbufs of type PBUF_REF, so these would all get
dropped for bad checksum.  This change addresses the problem and
simplifies things by stripping each header just once.
