Make tcp_connect() void; it will eventually have no failure case.
2006-04-30 02:13:52 +00:00

Put the TCP connection periodic processing in tcp.c, where it belongs.

Change semantics of network API so that packet-absorbing calls *always*
...
take ownership of the packet, rather than doing so only if they return
success. This breaks semantic compatibility with Linux's
hard_start_xmit() method, but means that we don't have to worry so much
about error cases.
Split mechanism of processing received packets (net_rx_process()) out
from policy (net_step()), preparatory to putting net_step() in a separate
object.
2006-04-29 17:17:43 +00:00

Added basic code for implementing co-operative multitasking.

Fix a couple of broken assertions, and align the buffer correctly.
2006-04-28 14:09:31 +00:00
79f64eea55
Transmit the buffer contents, not the buffer descriptor...

Add an explicit failure debug message
2006-04-28 14:07:41 +00:00

Create something that might be usable as a symbol list for bochs'
internal debugger.
2006-04-28 14:07:08 +00:00
d8e99bf28f
Gave up on adding POSIX errno's as required, and just added (almost) all
...
of them in one go.
EBADIMG has been replaced by ENOEXEC, and EIMGRET by ECANCELED.
2006-04-28 13:44:34 +00:00

Update to use POSIX-like API.
2006-04-25 12:04:07 +00:00
face774c4c
Fixed erroneous comparison
2006-04-25 11:54:58 +00:00
95f8a42930
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.
2006-04-25 10:41:49 +00:00
4e92f29c9e
Now passes trivial tests. free_memblock() needs neatening up.
2006-04-25 04:01:58 +00:00
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.
2006-04-25 03:30:46 +00:00
2f0d412210
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.
2006-04-24 23:00:32 +00:00

Added missing headers required for compilation in Etherboot.

We have our own ARP layer now.
2006-04-24 19:19:13 +00:00
fcf765e42d
Add missing {register,free}_netdev().
...
Tie into existing driver API; we'll fix that up soon.
2006-04-24 18:44:50 +00:00
832e86246b
gcc is rather over-aggressive about optimising out static data structures
...
even when __atribute__ (( unused )) is correctly set...
2006-04-24 18:31:37 +00:00
4c4e4de18f
(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.
2006-04-24 18:29:47 +00:00
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.

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

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

Prototype now clashes with the macro in arch/i386.
2006-04-24 15:27:58 +00:00
510ccb2900
Added __constant_memcpy() based on version in Linux's string.h.

First draft of a dynamic memory allocator
2006-04-24 15:21:18 +00:00
e323d1a29b
Add "net" directory.

Avoid including debug information in bin/%.s output, since the whole
point is to have easy-to-read assembler.
2006-04-24 15:20:01 +00:00
6209bd873a
First sketch of a new net device API.
2006-04-19 12:07:46 +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.
2006-04-19 11:32:24 +00:00
b89ccac02d
Updated to remove obsolete constants
2006-04-19 02:11:56 +00:00
3ca7dbe7ca
Added the concept of a network interface (a network-layer concept) as

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.
2006-04-19 02:05:50 +00:00

Update now that if_ether.h has moved.
2006-04-19 01:56:10 +00:00
4f3581e99c
Added ENOENT and EAFNOSUPPORT
2006-04-19 01:54:53 +00:00

2006-04-19 01:54:24 +00:00
744b895077
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
9f67ad9db0
First version. ARP protocol independence in less than the size of uIP's

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.
2006-04-05 11:44:56 +00:00
9ea782d339
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()

ee058362fa
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
a4a0244aa3
Moved uIP wrapper out of prototester.c and into proto/tcp.c.
2006-03-23 21:32:03 +00:00
17c0253ca0
Add include/gpxe as a directory to scan.
...
Exclude proto/uip, since uip.c and uip_arp.c both have global variables
called "c", which screws up doxygen's auto-generation of links to file
documentation when it encounters a file name such as "hello.c".
2006-03-23 21:06:36 +00:00
2bc7c746a6
Updated with "doxygen -u" from doxygen 1.4.4
2006-03-23 20:39:26 +00:00
05b284399e
Moved old tcp.h to old_tcp.h, to avoid name clash with new (uIP-based)
...
tcp.h.
2006-03-23 20:34:08 +00:00
af23ff8a24
Assertions are now handled via the POSIX-like <assert.h>.
2006-03-23 19:33:57 +00:00
55497b3402
Added missing #endif
2006-03-23 19:23:25 +00:00
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
531371efa2
Removed to make way for the uIP-based tcp.c.
2006-03-23 16:59:25 +00:00
dde1c5ad18
Moved include/in.h to include/gpxe/in.h, so that it can be included by
...
prototester.
2006-03-23 16:45:01 +00:00
eaf40883ff
Add Makefile for hijack and prototester utilities.
2006-03-23 13:11:41 +00:00
21c58729ae
Add debug symbols to objects. (They will be stripped out of the final
...
-Obinary build anyway, so it doesn't waste any space).
2006-03-23 13:09:29 +00:00
b2c94b32fc
Make the application state a void *.
2006-03-23 13:08:06 +00:00
218c26ff2b
Can now also print data sent by the remote side.
2006-03-23 13:06:08 +00:00
0d506a5c6a
Now capable of sending "Hello world!" via TCP.
2006-03-23 12:25:28 +00:00
911486fe41
Added basic http-specific option parsing
2006-03-22 22:35:32 +00:00
5263a5abf4
Started adding structure to allow for separate protocol tests, with
...
individual options.
Created the embryonic beginnings of a cleanly separated driver and
protocol stack API.
2006-03-22 21:25:35 +00:00
c32e83ad8d
Skeleton version: contains device driver (connecting to network via
...
hijack daemon) and a functional but very ugly and very primitive
wrapper around uIP.
This passes proof-of-concept testing; it successfully initiates a TCP
connection and responds to pings.
2006-03-22 02:23:20 +00:00
bb37bd47f8
Added from uip-0.9/uip/uip_arp.[ch]
2006-03-22 02:14:55 +00:00
417e896f0a
Remove htons(); it is provided elsewhere in Etherboot
2006-03-22 01:25:43 +00:00
1c7c24f21f
Basic, functional-but-extremely-pessimal versions (taken from

uip-0.9/unix/uip_arch.c).
2006-03-22 01:24:13 +00:00
c5a9c38606
Terminate cleanly on SIGINT or SIGHUP
2006-03-21 17:48:33 +00:00
e072baeb8c
Use libpcap API to send/receive packets.
...
Include automatic filtering (based on source MAC address of first
transmitted packet).
Proven to successfully elicit a ping response from a remote host.
2006-03-21 16:50:25 +00:00
4485df516c
Basic structure in place: can daemonise, listen on a Unix domain
...
socket, accept new connections, open a network interface using libpcap
and forward (all) traffic.
