2ff1b1245b Use start_timer_nodelay() in protocols which rely on the retry timer 
to generate the initial transmission; this cuts off around 0.3s per
instantiated connection.

9fd6a0418f Allowed zero-cost enforced ordering of features in startup banner 
list.

Added FEATURE() macros to most relevant (non-driver) files.

0acb016840 Add FEATURE() macro, plus code to display features at startup time, 
and generate DHCP options to indicate features to DHCP server (and to
PXE NBPs).

b34d4d0449 Separate the "is data ready" function of xfer_seek() into an 
xfer_window() function, which can return a scalar rather than a
boolean.

acd598b4f9 Don't build option-overloaded packets; they just confuse people (ISC

73fe1ba9dd Kill off job::start() (it was only ever added as part of an aborted

df0397f334 Update TFTP and FTP to take the same temporary URI scheme as HTTP 2007-01-15 09:58:26 +00:00
Michael Brown
4e20d73bb5 Gave asynchronous operations approximate POSIX signal semantics. This 
will enable us to cascade async operations, which is necessary in order to
properly support DNS.  (For example, an HTTP request may have to redirect
to a new location and will have to perform a new DNS lookup, so we can't
just rely on doing the name lookup at the time of parsing the initial
URL).

Anything other than HTTP is probably broken right now; I'll fix the others
up asap.

649b789e93 DHCP transmits via specified net device, so no need to create a dummy 
routing table entry just to fool ipv4.c any more.

88e38fa148 We don't actually have a stdio.h header file. Our printf() functions are 
defined in vsprintf.h.  (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)

There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.

6ac78f6aff added stdio.h to includes for DBG compilation 2006-09-27 05:57:06 +00:00

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

3611cb17b7 Initial (untested) implementation of TFTP over the new UDP API. 2006-08-08 23:45:52 +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
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.

ae277992c2 Request bootfile name; it doesn't seem to be automatically supplied by 
all servers.

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.
 2006-07-20 00:18:50 +00:00

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

0768670fd8 udp_open() takes ports in network-endian order. 2006-07-19 21:56:27 +00:00

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

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.

16fc9858db Beginnings of DHCP protocol implementation 2006-07-19 17:01:06 +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.

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

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

12da7ea475 Add (untested) code for parsing a received DHCP packet and constructing a 
DHCP options block from the contents.
