Removed incorrect comment; malloc() is inefficient only when the
...
alignment and size are both powers of two, and there's no way to
specify an alignment through the malloc() interface anyway.

Now passes trivial tests. free_memblock() needs neatening up.

b601a7d355
Updated memory allocator to improve support for unaligned or partially
...
aligned blocks.
Moved header to include/malloc.h, since we now also provide the
POSIX-like malloc()/free() pair.
Not yet tested.

Add __constant_flsl(), because it's useful for finding out the next
...
power-of-two up from a given constant via
( 1 << fls ( constant - 1 ) )
fls(), flsl(), ffs() and ffsl() appear in strings.h according to
POSIX.

Added missing headers required for compilation in Etherboot.

We have our own ARP layer now.

Add missing {register,free}_netdev().
...
Tie into existing driver API; we'll fix that up soon.

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

(librm_base-1b) is already an offset; no need to apply OFFSET().
...
Doing so, in fact, seems to expose an assembler bug; (a-b-0) is
apparently not the same as (a-b). Go figure.

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.

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.

Obviate uip_init(); our bss is zeroed at startup already.

Don't bother poisoning lists; it costs code size.

Prototype now clashes with the macro in arch/i386.
2006-04-24 15:27:58 +00:00

Added __constant_memcpy() based on version in Linux's string.h.

Added memswap().

Add "net" directory.
...
Avoid including debug information in bin/%.s output, since the whole
point is to have easy-to-read assembler.

First sketch of a new net device API.

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.
2006-04-19 11:32:24 +00:00
b89ccac02d
Updated to remove obsolete constants
2006-04-19 02:11:56 +00:00

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

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.

Update now that if_ether.h has moved.
2006-04-19 01:56:10 +00:00

Added ENOENT and EAFNOSUPPORT

Make flags more efficient.
...
Add 'raw' net_addr facility (needed for ARP).
2006-04-19 01:53:49 +00:00
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.
2006-04-19 01:52:41 +00:00

First version. ARP protocol independence in less than the size of uIP's
...
Ethernet-and-IPv4-only ARP module. :)

Added netmask and gateway global options.

Added iSCSI testing.
2006-04-05 11:46:18 +00:00
6446767258
First draft of iSCSI protocol support. Is capable of retrieving disk

blocks.

Make pcap_inject non-static, so that its prototype doesn't conflict with
...
the real pcap_inject in the case where we do have it.
2006-04-05 11:44:05 +00:00
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
988bb50979
Added set_netmask() and set_gateway()

We don't need to know anything about ARP
2006-03-24 17:39:05 +00:00
90892d5ec7
Allow specifying the local IP address via --from.
2006-03-24 17:28:40 +00:00
b44332eb7d
Split non-TCP portions of the stack out into ip.[ch].
...
Added set_ipaddr().
2006-03-24 17:22:09 +00:00
1c607470e3
Put in a substitute pcap_inject() function, since earlier versions of
...
libpcap are lacking the function. For now, we always use the
substitute version, since there's no easy way to determine whether or
not we need it.
2006-03-24 16:43:12 +00:00
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
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
99032becce
Pick up the gPXE include files when building prototester.
2006-03-23 21:35:20 +00:00
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.
2006-03-23 21:34:25 +00:00
