1961ba44e1 Added generic SPI protocol handler with read and write support. 2006-12-04 18:32:55 +00:00
Michael Brown
946967f09c Abstracted out part of the concept of an SPI device to a generalised NVS 
device.

Separated the mechanisms of non-volatile storage access and non-volatile
stored options.

dc06c895fc Changed length parameter in SPI methods to be a byte length, rather than 
a word length.
 2006-12-04 16:09:59 +00:00
Michael Brown
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.

2e41bfd268 Force syntax-checking on assertions even in non-asserting builds. 2006-12-04 15:09:57 +00:00
Michael Brown
3e0286dee3 Move ANSI C standard prototypes to stdlib.h; leave the gPXE-specific 
function prototypes (e.g. malloc_dma()) in malloc.h.

3f0b4d9ed8 Updated to use asynchronous operation model for iSCSI requests 
Added CHAP authentication
 2006-11-28 00:29:02 +00:00
Michael Brown
82342e0b8f Marked memcmp/strcmp as "pure" functions, to allow gcc to optimise 
away code such as

  if ( strcmp ( some_string, "some_value" ) != 0 ) {
     DBG ( "Bad value received!" );
  }
 2006-11-27 23:50:24 +00:00
Michael Brown
c4677c7e73 Implemented realloc(), and changed the semantics of malloc(0) to allow 
for realloc(0) being a valid way to free memory.
 2006-11-24 16:51:18 +00:00

fdaddd969a Added "name" field to digest algorithms 2006-11-21 16:14:50 +00:00
Michael Brown
c5428303e4 Added generic CHAP layer, independent of iSCSI 2006-11-21 13:26:59 +00:00
Michael Brown
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.
 2006-11-15 04:22:22 +00:00
Michael Brown
fedc186fd7 Split login into security negotation and operational parameter 
negotiation phases, to allow inclusion of CHAP authentication.

Michael Brown
75d26d884a Added pxe_netdev; a slight hack for now, but will need to be done 
properly for the PXE UNDI API anyway.
 2006-08-09 02:58:27 +00:00
Michael Brown
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

41af7457a8 Merge of Fredrik Hultin command_line 2006-08-09 02:30:35 +00:00
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.

d1a123b1f4 Added TFTP test code (currently just dumps file to console). 2006-08-09 00:09:29 +00:00
Michael Brown
3611cb17b7 Initial (untested) implementation of TFTP over the new UDP API. 2006-08-08 23:45:52 +00:00

eda79ec32b The prototype for strcasecmp() is apparently in strings.h. 2006-08-08 22:52:16 +00:00
Michael Brown
72cd29f13c Added some TFTP definitions for use with the new UDP API. 2006-08-08 22:01:16 +00:00

cb42e573a0 Added retransmissions to TCP 2006-08-07 18:52:26 +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
Michael Brown
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.

beadd82208 Remove unused functions. 2006-08-01 14:26:02 +00:00
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

3a0e293123 Renamed tcpip_if.[ch] to tcpip.[ch] 2006-08-01 14:18:09 +00:00

Michael Brown
00a1f000b1 Added dhcp_ipv4_option() and friends. 
Added test code to configure the interface for IPv4 after DHCP.
 2006-07-20 02:49:59 +00:00

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

parsed DHCP responses.

ab577e1a3a The following edits were made: \ 
1. Updated UDP send data code\

3. Moved udp_buffer() and udp_buflen() to udp.c from udp.h
 2006-07-19 16:25:23 +00:00
Michael Brown
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
Michael Brown
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.
 2006-07-17 13:07:14 +00:00
Michael Brown
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.
 2006-07-15 19:24:55 +00:00

Michael Brown
51d62d1a3c Provide a mechanism for returning the encapsulator as well as the 
encapsulated option; this will be needed for modifications to the options
block.
 2006-06-28 18:59:54 +00:00
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. 2006-06-28 15:43:08 +00:00

0bcaa8a21f First stab at DHCP option handling in a way that will allow us to have 
multiple option sources (e.g. multiple DHCP replies, non-volatile
storage etc.)
 2006-06-27 17:24:07 +00:00

e442447f37 - multiple static inline definitions added

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.
