Michael Brown	df868476e7	Various warnings fixups for OpenBSD with gcc-3.3.5.	vor 16 Jahren
Michael Brown	423e9d72f3	udp_open_promisc() calls udp_open_common() with peer==NULL.	vor 16 Jahren
Michael Brown	b34d4d0449	Separate the "is data ready" function of xfer_seek() into an xfer_window() function, which can return a scalar rather than a boolean.	vor 17 Jahren
Michael Brown	ca4c6f9eee	Kill off unused request() method in data-xfer interface.	vor 17 Jahren
Holger Lubitz	389c63d7c4	convert to zalloc	vor 17 Jahren
Michael Brown	5de837cc67	Mildly ugly hack to force correct linkage.	vor 17 Jahren
Michael Brown	07dc294de8	Update DHCP to use data-xfer interface (not yet tested).	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	e381714c07	Partial migration of UDP to data-xfer interface. (Will not link at present; DHCP is broken).	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
Anselm Martin Hoffmeister	ff5aac826a	hoffmeis: Fixing situation where absence of a newdata() handler for UDP connections might break things. Only-sending applications like syslog() do not need a newdata() handler, so added a check if that handler exists.	vor 17 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 17 Jahren
Michael Brown	bcdb6fad3e	Improve debug messages	vor 17 Jahren
Michael Brown	753e156844	Allow udp_{send,sendto,sendto_via} to be called outside of the udp_senddata() callback. This will simplify any UDP protocols that don't need the temporary buffer.	vor 17 Jahren
Michael Brown	c821a7b20d	Add udp_sendto_via() to allow e.g. DHCP to transmit without first having to set up dummy routing entries.	vor 17 Jahren
Michael Brown	f008b77ba2	Allow an explicit network device to be specified for IP-layer transmissions.	vor 17 Jahren
Michael Brown	18e5353bed	Rename pkb_available() to pkb_tailroom() for consistency with Linux's skb_tailroom(). Add pkb_headroom().	vor 17 Jahren
Michael Brown	20681d6168	Allow empty checksums on received packets	vor 17 Jahren
Michael Brown	94fc68895d	Improve consistency between TCP and UDP RX datapaths	vor 17 Jahren
Michael Brown	a0525a4ed3	Verify checksums on the RX datapath. Simplify checksum generation on the TX datapath.	vor 17 Jahren
Michael Brown	88e38fa148	We don't actually have a stdio.h header file. Our printf() functions are defined in vsprintf.h. (This may change, since vsprintf.h is a non-standard name, but for now it's the one to use.) There should be no need to include vsprintf.h just for DBG() statements, since include/compiler.h forces it in for a debug build anyway.	vor 18 Jahren
Marty Connor	6ac78f6aff	added stdio.h to includes for DBG compilation	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
Michael Brown	eb24eece0e	Convert some trivial functions to static inlines.	vor 18 Jahren
Michael Brown	ffe0e24249	Make the UDP senddata() methods return a status code. udp_connect() now follows the standard BSD sockets semantics and simply sets the default address for outgoing packets; it doesn't filter incoming packets.	vor 18 Jahren
Michael Brown	a0a872f7f1	Updated PXE UDP implementation to use the new Etherboot UDP API. Updated PXE API dispatcher to use copy_{to,from}_user, and moved to arch/i386 since the implementation is quite architecture-dependent. (The individual PXE API calls can be largely architecture-independent.)	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
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	21c3d63c2e	We shouldn't need to allocate a TX packet buffer when calling newdata(); if the application wants to send data then it will have to use the normal senddata() mechanism.	vor 18 Jahren
Michael Brown	29b358dd39	conn->local_port is now network-endian; do not swap when comparing against value in header. Temporarily disable RX checksumming; it's broken and is holding up work on higher-layer protocols .	vor 18 Jahren
Michael Brown	2c0eb6eb1d	Correct TCP/IP checksum generation.	vor 18 Jahren
Nikhil Chandru Rao	13dbf5494d	Minor edits	vor 18 Jahren
Michael Brown	a38010fb0e	Make udp_send() call udp_sendto(), rather than vice-versa.	vor 18 Jahren
Michael Brown	7c84b74185	A small but very critical bug.	vor 18 Jahren
Michael Brown	82f3295794	Use more standardised format specifiers in debug messages (e.g. %p for a pointer).	vor 18 Jahren
Michael Brown	ab633f6a73	Reserve space for lower-layer headers when allocating packet buffer. Use pkb_available() rather than pkb_len() (which will always return 0 on a freshly allocated buffer). udp_send() should assume that the buffer has already been allocated.	vor 18 Jahren
Nikhil Chandru Rao	bf515d3d65	Minor edit in net/udp.c	vor 18 Jahren
Nikhil Chandru Rao	ab577e1a3a	The following edits were made: \ 1. Updated UDP send data code\ 2. Corrected internet checksum\ 3. Moved udp_buffer() and udp_buflen() to udp.c from udp.h	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	a6c6b3d739	Fixed whitespaces; updated UDP code	vor 18 Jahren
Nikhil Chandru Rao	74339b3c6e	updated UDP interface	vor 18 Jahren
