Michael Brown	54fbd11221	[build] Keep gcc 4.4 happy gcc 4.4 adds another few warnings, and also seems to complain if we place %ebp in the clobber list for any inline asm.	vor 16 Jahren
Michael Brown	6b9cc25556	[netdevice] Split multicast hashing out into an mc_hash method Multicast hashing is an ugly overlap between network and link layers. EFI requires us to provide access to this functionality, so move it out of ipv4.c and expose it as a method of the link layer.	vor 16 Jahren
Michael Brown	1dcc60e5ad	[IPv4] Fix multicast address checking From: Viswanath Krishnamurthy <viswa.krish@gmail.com> The current ipv4 incorrectly checks the IP address for multicast address. This causes valid IPv4 unicast address to be trated as multicast address For e.g if the PXE/tftp server IP address is 192.168.4.XXX where XXX is 224 or greater, it gets treated as multicast address and a ethernet multicast address is sent out on the wire causing timeouts	vor 16 Jahren
Michael Brown	92d15eff30	[Settings] Remove assumption that all settings have DHCP tag values Allow for settings to be described by something other than a DHCP option tag if desirable. Currently used only for the MAC address setting. Separate out fake DHCP packet creation code from dhcp.c to fakedhcp.c. Remove notion of settings from dhcppkt.c. Rationalise dhcp.c to use settings API only for final registration of the DHCP options, rather than using {store,fetch}_setting throughout.	vor 16 Jahren
Michael Brown	978865da2f	[IPv4] Use default netmasks when no subnet mask is specified.	vor 16 Jahren
Michael Brown	aec9b8a41b	[Settings] Use a settings applicator to configure IPv4 routes.	vor 16 Jahren

Michael Brown	5b52630a9c	Never attempt to route the broadcast address.	vor 17 Jahren
Michael Brown	f77815f2b1	Kill off hotplug.h and just make net devices normal reference-counted structures. DHCP still broken and #if 0'd out.	vor 17 Jahren
Michael Brown	3e2c6b6736	pkbuff->iobuf changeover Achieved via Perl using: perl -pi -e 's/pk_buff/io_buffer/g; s/Packet buffer/I\/O buffer/ig; ' \ -e 's/pkbuff\.h/iobuf.h/g; s/pkb_/iob_/g; s/_pkb/_iob/g; ' \ -e 's/pkb/iobuf/g; s/PKB/IOB/g;'	vor 17 Jahren
Michael Brown	73b09ecba6	Use stdio.h instead of vsprintf.h	vor 18 Jahren
Michael Brown	5ff23aa406	Include stdlib.h rather than malloc.h	vor 18 Jahren
Michael Brown	f11da20f25	When a network device is specified to tcpip_tx() or it's children, treat it as a fallback network device rather than an explicitly forced network device. Clear routing table entries before re-attempting DHCP.	vor 18 Jahren
Michael Brown	1a1fc23417	Improve debugging	vor 18 Jahren
Michael Brown	c953c1a1c3	Use -ENETUNREACH to mean "no reachable network device exists, don't bother retrying".	vor 18 Jahren

Michael Brown	cc9b32c405	Remove uIP; we haven't used it for quite some time now.	vor 18 Jahren
Michael Brown	f008b77ba2	Allow an explicit network device to be specified for IP-layer transmissions.	vor 18 Jahren
Michael Brown	98b6154c3e	Add "name" field to network device, to facilitate netdev commands.	vor 18 Jahren
Michael Brown	35b5e5d3f5	Minirouting table entries hold a persistent reference to a net_device.	vor 18 Jahren
Michael Brown	a0525a4ed3	Verify checksums on the RX datapath. Simplify checksum generation on the TX datapath.	vor 18 Jahren
Michael Brown	285beeff7c	Tidy up debug messages Move routing into a separate function	vor 18 Jahren
Michael Brown	718294553b	Fix compiler warning	vor 18 Jahren
Michael Brown	867c7aef59	iphdr->hlen includes the IP header, so truncate packet before stripping the header. Also fix an htons/ntohs confusion.	vor 18 Jahren
Marty Connor	ee9ae8130a	Remove _PROTOCOL macros for gcc 3.2 compatibility	vor 18 Jahren
Michael Brown	a3d508b648	Clarified packet ownership transfer between a few functions. Added a large number of missing calls to free_pkb(). In the case of UDP, no received packets were ever freed, which lead to memory exhaustion remarkably quickly once pxelinux started up. In general, any function with _rx() in its name which accepts a pk_buff must either call free_pkb() or pass the pkb to another _rx() function (e.g. the next layer up the stack). Since the UDP (and TCP) layers don't pass packet buffers up to the higher-layer protocols (the "applications"), they must free the packet buffer after calling the application's newdata() method.	vor 18 Jahren
Nikhil Chandru Rao	409f69a08a	Changed ipv4_dump() to consume only one line.	vor 18 Jahren
Michael Brown	68e33224ef	gcc3 compatibility: removed ARP_NET_PROTOCOL().	vor 18 Jahren
Nikhil Chandru Rao	d2bdf81505	Removed some bugs in TCP	vor 18 Jahren
Michael Brown	885a630ddf	Fix routing when a gateway exists. This should probably be split into a separate function.	vor 18 Jahren
Nikhil Chandru Rao	6714ec745a	Minor corrections	vor 18 Jahren
Michael Brown	467e9627cc	Added features that will be required for PXE UDP support. Introduced struct sockaddr_tcpip, to simplify code that deals with both IPv4 and IPv6 addresses. Reorganised parts of tcpip.c and udp.c.	vor 18 Jahren
Nikhil Chandru Rao	c24546c70b	Minor changes to the network layer rx() functions	vor 18 Jahren
Michael Brown	1ebb68e49a	Renamed trans_{rx,tx}() to tcpip_{rx,tx}(), since they are specific to the TCP/IP protocol suite (rather than being general transport-layer functions).	vor 18 Jahren
Michael Brown	3a0e293123	Renamed tcpip_if.[ch] to tcpip.[ch]	vor 18 Jahren
Michael Brown	36c94eae78	Clarify hexiness of header length	vor 18 Jahren
Michael Brown	2c0eb6eb1d	Correct TCP/IP checksum generation.	vor 18 Jahren
Nikhil Chandru Rao	5f651f8622	Added fragment reassembly code	vor 18 Jahren
Nikhil Chandru Rao	c9ea710930	Renamed net/interface.c and include/gpxe/interface.h to net/tcpip_if.c and include/gpxe/tcpip_if.h respectively. Made changes in the other files.	vor 18 Jahren
Nikhil Chandru Rao	6e2c97b0c0	Added ipv4_pseudo_header structure	vor 18 Jahren
Nikhil Chandru Rao	41b399d672	Fixed endianness of 16- and 32- bit values	vor 18 Jahren
Michael Brown	35557914e3	Simplify ipv4_tx() by not having a separate "source" variable now that we are constructing the IP header ourselves. Formatting fix-ups (80 column limit is mandatory!)	vor 18 Jahren
Michael Brown	b49de73950	Factorise out common code	vor 18 Jahren
Michael Brown	e517a4771b	Split ipv6 functions out from ipv4.c	vor 18 Jahren
Michael Brown	e04ea505c9	Whitespace fixes	vor 18 Jahren
Nikhil Chandru Rao	90fbff8f34	added support for processing and transmitting without uIP	vor 18 Jahren
Michael Brown	8637834031	Made the temporary buffer part of the TCP senddata() API, to ease the transition away from uIP. Prepared ipv4.c for transition away from uIP.	vor 18 Jahren
Michael Brown	3c8aafa209	Simplify RX data path. Kill off the static single net device and move to proper dynamic registration (which we need with the new device model). Break the (flawed) assumption that all network-layer protocols can use ARP; such network-layer protocols (i.e. IPv4) must now register as an ARP protocol using ARP_NET_PROTOCOL() and provide a single method for checking the existence of a local network-layer address.	vor 18 Jahren
Michael Brown	bbd9e28061	Simplify TX datapath.	vor 18 Jahren
