931f94dca3 Generalised the SPI abstraction layer to also be able to handle interfaces 
that don't provide the full flexibility of a bit-bashing interface.

Temporarily hacked rtl8139.c to use the new interface.

57d539aab0 Made it temporarily possible to call MD5 routines directly from external 
code, rather than going through the digest layer.

Removed a spurious line of constants.

e9561aafc0 Derive xid dynamically from the netdev, so that we can call 
create_dhcp_packet() from pxe_preboot.c, after the dhcp_session is long
gone.

Expose the functions required by pxe_preboot.c

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.

d1a123b1f4 Added TFTP test code (currently just dumps file to console). 2006-08-09 00:09:29 +00:00

ecdcdea1af Remove unused attribute from __table macros; the tables are no longer 
static since otherwise gcc4 optimises them away completely.  Also, it
really *is* an error if the table start and end are unused, so they
certainly shouldn't be marked with attribute unused.
 2006-08-07 17:06:31 +00:00

eb24eece0e Convert some trivial functions to static inlines. 2006-08-03 23:42:03 +00:00
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.
 2006-08-03 23:10:14 +00:00
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.)

e24a6cb525 Moved the basic struct sockaddr out of in.h. 2006-08-02 00:06:30 +00:00
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.

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).
 2006-08-01 14:22:04 +00:00

224529d8dd Now capable of sending what, to me, looks like a valid DHCPDISCOVER 
(apart from the bad UDP checksum).

b8d619e822 Added macros for generating static DHCP options 2006-07-19 16:16:51 +00:00
Michael Brown
254fe6e00e Split DHCP packet creation into two parts: creating the basic packet 
structure, and populating it with options.  This should allow us to
use the same basic options list for both DHCPDISCOVER and DHCPREQUEST,
plus making it much easier to set the non-constant parameters
(e.g. requested IP address) in request packets.
 2006-07-19 12:12:45 +00:00
Michael Brown
e40ebb67de Allow for calling find_dhcp_option() with "options" set to NULL, in order 
to search through all registered option blocks.

Move some static inlines that are likely to be used frequently into
dhcpopts.c as normal functions, to save space.
 2006-07-19 11:05:38 +00:00

6c01d3bb95 Fix creation of the htype field; the ll_proto field from which it is 
derived is a 16-bit big-endian field, but htype is only 8 bits wide.

b24947f0c0 Add sketch code to reassemble a DHCP packet from our internal "everything 
is a DHCP option" data structures.

We need this code in order to be able to return a DHCP packet to a PXE NBP
which reflects options from our multiple sources (e.g. NVS and DHCP
server).  This is expensive, but necessary.  Having paid this cost, we may
as well try to use the same code to generate our DHCP request packets,
since the process is similar.
 2006-07-17 12:47:22 +00:00
Michael Brown
12da7ea475 Add (untested) code for parsing a received DHCP packet and constructing a 
DHCP options block from the contents.

51d62d1a3c Provide a mechanism for returning the encapsulator as well as the 
encapsulated option; this will be needed for modifications to the options
block.

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.

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.

Michael Brown
ab4f96e525 Move per-transition delays from generic bit-bashing layer to i2c layer 
(since SPI bit-bashing will require different delay semantics).

48fb6c6dc2 Updated retry timer mechanism to incorporate smoothed RTT estimation. 
AoE now uses the retry timer mechanism.
 2006-06-01 14:33:52 +00:00
Michael Brown
1f394c2f7c Backing out last change; no immediate plans to make the whole block-device 
layer asynchronous, so keeping the sync/async boundary within aoedev.c
seems cleanest for now.
 2006-06-01 11:14:59 +00:00
Michael Brown
99ef98d0bf ATA devices are now asynchronous. The ATA layer itself now performs the 
async_wait(), though we may wish to move this higher up the stack, and
consider making the block device model asynchronous.  (There is only a
marginal cost for synchronous devices, since they can simply call
async_done() before returning; async_wait() will work seamlessly in this
situation).
 2006-05-31 18:57:11 +00:00
Michael Brown
68125bc441 Added generic asynchronous operations code. 
Removed data_in_len and data_out_len from ata_command structure; the
lengths are implied by the sector count and the presence of the data_in
or data_out pointers.

Changed AoE code to use subcommands by default, and made aoe_issue()
nonblocking (with completion via async_wait()).
 2006-05-31 14:34:17 +00:00
Michael Brown
1db1a6dad3 Added first sketch of a generic retry timer mechanism. The idea is to use 
these timer objects in AoE and UDP protocols (where there is no underlying
retransmission mechanism) without requiring each protocol to implement its
own individual retry logic.  Eventually, we should be able to use the same
timer code for TCP retransmissions as well.

6541338897 Handle multi-sector reads by splitting them into subcommands. 2006-05-29 08:25:31 +00:00
Michael Brown
9a2a52693d Initial AoE implementation. Limitations are: 
Cannot yet handle reads of more than two sectors

  No retransmission

  No way to find out a target's MAC address (this proof of concept uses
  broadcasts)

These limitations shall not last long!  :)
 2006-05-28 23:29:43 +00:00
Michael Brown
6f998cecb3 Use separate data-in and data-out buffers. 
Increase code simplicity at the expense of around 64 bytes.

6d6252067f Add ETH_P_AOE 2006-05-28 21:47:52 +00:00

f743de4858 Added tcp_kick(). This speed up LILO and GRUB booting by almost two 
orders of magnitude.

Michael Brown
6c50564724 Make PKB_ZLEN the minimum possible size of packet buffer (to allow for 
hardware that can't autopad).
