832e86246b gcc is rather over-aggressive about optimising out static data structures 
even when __atribute__ (( unused )) is correctly set...

824d6ffa7f Header rearrangement. 
I want to get to the point where any header in include/ reflects a
standard user-level header (e.g. a POSIX header), while everything that's
specific to gPXE lives in include/gpxe/.  Headers that reflect a Linux
header (e.g. if_ether.h) should also be in include/gpxe/, with the same
name as the Linux header and, preferably, the same names used for the
definitions.

53f78346bf Network API now allows for multiple network devices (although the 
implementation allows for only one, and does so without compromising on
the efficiency of static allocation).

Link-layer protocols are cleanly separated from the device drivers.

Network-layer protocols are cleanly separated from individual network
devices.

Link-layer and network-layer protocols are cleanly separated from each
other.

5423f876fb Don't bother poisoning lists; it costs code size. 2006-04-24 15:28:56 +00:00

bdc8190c8d Remove the concept of the media-independent link-layer header and replace 
it with metadata in the pkb structure.  This is required since UNDI will
want to be able to parse the link-layer header without destroying it.

3ca7dbe7ca Added the concept of a network interface (a network-layer concept) as 
separate from a network device (a link-layer concept).

2558439ce4 First version, based on include/linux/list.h, stripped down to just 
those functions we are likely to need.

Still need to come up with a way of getting the linker to create
static lists using this linking mechanism.

744b895077 Make flags more efficient. 
Add 'raw' net_addr facility (needed for ARP).
 2006-04-19 01:53:49 +00:00
Michael Brown
49f933fbc3 Moved if_ether.h and if_arp.h to include/gpxe, for consistency with Linux 
kernel.

Removed obsolete struct arprequest from if_arp.h and put it in nic.c so
that nic.c will still compile.  ARP will very shortly be handled by
net/arp.c instead.

6446767258 First draft of iSCSI protocol support. Is capable of retrieving disk 
blocks.

c8a7133e9f Added tcp_buffer, to give applications a zero-cost place to build data to 
be transmitted.
 2006-04-05 11:43:01 +00:00
Michael Brown
988bb50979 Added set_netmask() and set_gateway() 2006-04-05 11:41:15 +00:00

b44332eb7d Split non-TCP portions of the stack out into ip.[ch]. 
Added set_ipaddr().

7e61f38799 Moved "hello world" protocol implementation out of prototester.c and into 
the first standalong uIP-based protocol module.
 2006-03-23 22:37:05 +00:00
Michael Brown
508dcdb303 Added container_of(). This seems about the best place to put it, since 
the definition of it uses offsetof(), and the two concepts are related.
 2006-03-23 22:07:21 +00:00
Michael Brown
2299435f1c Added prototype for inet_ntoa, even though we don't have the function 
yet, in order to allow prototester.c to compile.  It might be worth
changing all the uses of "%@" in printf to use "%s" and inet_ntoa
instead, in order to improve the portability of our code.

a4a0244aa3 Moved uIP wrapper out of prototester.c and into proto/tcp.c. 2006-03-23 21:32:03 +00:00
Michael Brown
05b284399e Moved old tcp.h to old_tcp.h, to avoid name clash with new (uIP-based) 
tcp.h.

af23ff8a24 Assertions are now handled via the POSIX-like <assert.h>. 2006-03-23 19:33:57 +00:00
Michael Brown
55497b3402 Added missing #endif 2006-03-23 19:23:25 +00:00
Michael Brown
cb8e89de15 Added assert.h, with assert() defined (almost) as per POSIX, and 
linker_assert() defined as gPXE-specific.
 2006-03-23 17:28:51 +00:00
Michael Brown
dde1c5ad18 Moved include/in.h to include/gpxe/in.h, so that it can be included by 
prototester.

33dbdda28e Allow data blocks to be less than sizeof ( struct buffer_free_block ) in 
size.  (The restriction on the size of free blocks remains.)

f2198e8a65 Don't choke on duplicate OACK packets. 
Make await_tftp() static and create tftp_get() for fetching the next TFTP
packet instead.

53a4436d94 TFTP upgraded to use a core function library (in tftpcore.c) which will be 
shared between TFTP, TFTM and MTFTP protocols.

92f1a5c677 Documented the purpose of the two timeout fields in 
s_PXENV_TFTP_READ_FILE.

6e74dc3460 Added implementation note on IP routing.
