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

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.

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).

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

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.

32d9f25a6f Fixed up and made work a PBUF_REF type. Most of the code uses this now
instead of PBUF_ROM. This addition allows support of copy-on-demand where the
lower layers can call pbuf_unref() which tests for any PBUF_REF buffers and
replaces them with PBUF_POOL buffers. This is now used
everywhere. pbuf_unref() is called in ARP queueing and in the coldfire
driver, which puts frames on a DMA queue and frees them later.

Along with this change pbuf_free() now goes through the entire chain of
buffers and tests all the ref counters, not just the first one. Generally now
pbuf_ref_chain() should be called and not pbuf_ref(). This change was made
because it is possible for the head of the pbuf chain to have a different
count than the payload pbuf which might have been passed by the application.

dd2fa15e8a Add the following features and bugfixes:
Added select() functionality to sockets library.
Support for errno in sockets library.
Byte ordering fixes.
basic lwip_ioctl(), FIONREAD, get/setsockopt() etc. support

- added additional argument to netif_add to pass state pointer so that the
if_init function has access to context information before
the interface is added, without accessing globals.

- added netif_remove()

- to conserve cpu load the tcpip_tcp_timer should only be active
when tcbs that need it exist.

- pass length of available data to callbacks for NETCONN_EVT_RCV events

- added tcpip_link_input(), a hack to allow processing of PPP
packets in tcpip_thread() context. This saves threads and context
switches.

- renamed incompatible ASSERT() macro to LWIP_ASSERT() to avoid name
collision.

- changed a bunch of %d's to %u's in format strings for unsigned values.

- added ip_frag to lwip_stats.

- changed IP_REASS_MAXAGE and IP_REASS_TMO defaults to more realistic
values.

- added sys_timeout_remove() function to cancel timeouts (needed by PPP
amongst other things).

- tolerate NULL returns from sys_arch_timeouts() since some threads might
not need to use or have timeouts.

- added sys_sem_wait_timeout()

- moved mem_malloc() function to end of mem.c to work around tasking
compiler bug.

- automatically bind to local tcp port if 0.

- allow customization of port ranges for automatic local bindings.

- corrected various typos, spelling errors, etc..

Thanks to Marc Boucher for many of these changes.
