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

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.

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).

21c3d63c2e We shouldn't need to allocate a TX packet buffer when calling newdata(); 
if the application wants to send data then it will have to use the normal
senddata() mechanism.

9e761f5f28 Print out "DHCP..." message just in case people think the demo is sitting 
there doing nothing when it's actually waiting for a DHCP reply.

a92d242008 Allow an AoE boot to be directed via DHCP, so that we have a proof of 
concept demo that actually does something useful.

3085f03ad4 Request Etherboot encapsulated options. 
Parameter request list is yet another option that ISC dhcpd ignores
unless it's in the main options block.

Fix logic error in parsing file and sname fields.

9ad5cede96 Set DHCP_MESSAGE_TYPE option within the main options block. This 
doesn't seem to be required by the RFCs, but at least ISC dhcpd and
ethereal refuse to recognise it otherwise.

881b90e82c Packets without a DHCP_MESSAGE_TYPE option are probably just BOOTP 
packets.

29b358dd39 conn->local_port is now network-endian; do not swap when comparing 
against value in header.

Temporarily disable RX checksumming; it's broken and is holding up
work on higher-layer protocols
.

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

82f3295794 Use more standardised format specifiers in debug messages (e.g. %p for 
a pointer).

ab633f6a73 Reserve space for lower-layer headers when allocating packet buffer. 
Use pkb_available() rather than pkb_len() (which will always return 0
on a freshly allocated buffer).

udp_send() should assume that the buffer has already been allocated.

e8daeb62b1 Eliminate confusion between functions that return pointers and 
functions that return status codes.

Zero the DHCP packet buffer *before* creating the options structures
inside it.

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

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.
