Michael Brown 21f3789ec8 Swap downstream/upstream order so that debug messages for filters show 
up in the same colour as debug messages for the application stream.
 2007-01-31 03:43:40 +00:00
Michael Brown e38e516463 Add insert_filter() function 2007-01-31 03:04:56 +00:00

Michael Brown 2f7eac1646 Low-overhead filter streams 2007-01-30 12:17:03 +00:00
Michael Brown ddf3b56d47 Definition of a (hopefully) generic stream API 2007-01-30 12:16:36 +00:00
Michael Brown 1a79437888 Added async_block_progress() and default SIGUPDATE handler. 2007-01-29 04:15:24 +00:00
Michael Brown c42a384709 Moved most buffer debug messages to DBG2. 
Make expand_buffer() a non-inline function, so that we can add debug
messages.

Expandable buffers now don't *always* round up to the next power of two.
This allows e.g. loading a 137MB ISO image on a machine with only 256MB
RAM...
 2007-01-29 04:12:29 +00:00
Michael Brown bf9ec8102f Add 64-bit rotates 2007-01-26 02:53:30 +00:00
Michael Brown da9dc834b1 Help quick testing of building Linux code inside gPXE 2007-01-24 23:38:05 +00:00
Michael Brown 9cf5c4557d Add Linux-compatible rol32/ror32 functions. Amazingly, gcc will 
optimise these down to the correct single "roll"/"rorl" instruction.
 2007-01-24 23:31:58 +00:00
Michael Brown f4c1e564a1 vsprintf.h is gPXE-specific; move it to include/gpxe 2007-01-19 01:17:23 +00:00
Michael Brown 4e3976711d A working name resolution framework 2007-01-18 22:38:13 +00:00
Michael Brown 075f8144ff Have DHCP set the nameserver, rather than DNS read the DHCP nameserver 
value.
 2007-01-18 21:22:03 +00:00
Michael Brown c014f607a8 Use total free memory as advertised window. This seems to be sufficient 
to avoid drops even on slow NICs.
 2007-01-18 20:39:17 +00:00
Michael Brown 6d4e37cf42 Move include/malloc.h to include/gpxe/malloc.h, since everything in there 
is now gPXE-specific.  (The standard malloc() et al have been in stdlib.h
for a while).

Add free memory counter.
 2007-01-18 20:11:04 +00:00
Michael Brown 5b00fbade3 Increase window size to 64kB. Line rate downloads on a 100Mbps link, 
anyone?
 2007-01-18 16:39:55 +00:00
Michael Brown c8b3e969a0 Allow buffers to be pre-expanded on demand. 2007-01-18 15:13:41 +00:00
Michael Brown dd6d94004f HTTP/DNS now working fully asynchronously. HTTP/IP addresses and any 
other protocol won't work at the moment.
 2007-01-18 03:39:45 +00:00
Michael Brown 0b11733b75 Replacement for fetch() which operates asynchronously and identifies 
protocols by URI scheme.
 2007-01-18 03:37:05 +00:00
Michael Brown 99e58865c7 Use struct sockaddr rather than struct sockaddr_tcpip 
Tidy up code
 2007-01-18 03:35:00 +00:00
Michael Brown 6601a7da6a Added async_uninit() to simplify failure paths. 2007-01-18 03:29:40 +00:00
Michael Brown 5a807994d8 Add utility function to parse port from URI 2007-01-18 03:28:55 +00:00
Michael Brown 8ffbbebf11 Ensure that struct sockaddr is long enough... 2007-01-18 03:28:29 +00:00
Michael Brown 544fa25928 Rename e{malloc,realloc,free} to u{malloc,realloc,free}, to more obviously 
reflect the fact that they allocate and deallocate user memory (i.e.
things reached through a userptr_t).
 2007-01-16 08:36:42 +00:00
Michael Brown ff8528ea9a Create and use async_block() macro; it cuts down on the visual overhead 
of blocking on asynchronous operations, when that isn't an important
aspect of the code.
 2007-01-16 08:10:54 +00:00
Michael Brown 9af12d5fba A working DNS resolver (not yet tied in to anything) 2007-01-15 17:31:35 +00:00
Michael Brown df0397f334 Update TFTP and FTP to take the same temporary URI scheme as HTTP 2007-01-15 09:58:26 +00:00
Michael Brown c676591cd1 Unmaintained example code is probably worse than useless. 2007-01-15 09:06:12 +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.
 2007-01-15 08:49:10 +00:00
Michael Brown 26166cf5e0 Added a URI parser that should be standards conformant. (It can certainly 
handle something as convoluted as

 2007-01-14 23:48:31 +00:00
Michael Brown 99272f958b Typo 2007-01-14 15:13:33 +00:00
Michael Brown 10c9b03cdb Actually, the initrd image should be architecture-independent. 2007-01-14 15:07:11 +00:00
Michael Brown 784e10635a Can almost start a kernel now. It dies with "No setup signature found" 2007-01-14 06:36:20 +00:00
Michael Brown 797edf28b7 Replace image->entry with image->priv. 2007-01-14 04:04:28 +00:00
Michael Brown dca369ddc3 Call hide_etherboot() from startup(), rather than requiring the prefix to 
do it.
 2007-01-14 00:53:56 +00:00
Michael Brown c2708df14a Make shutdown functions callable by OS image's exec methods. 2007-01-14 00:16:41 +00:00
Michael Brown aaed3d50a8 Some operating systems get a nasty shock if a region of the E820 map seems 
to start on a non-page boundary.  Make life safer by rounding out our
edited regions.
 2007-01-13 23:38:33 +00:00
Michael Brown 526d314266 Advertise a larger MSS to improve TCP performance. 2007-01-13 17:36:17 +00:00
Michael Brown 497c3a5aad Fixed HTTP 2007-01-12 19:18:13 +00:00
Michael Brown 369754f959 Whitespace fix 2007-01-12 19:17:25 +00:00
Michael Brown 83b7933f8a Damn it; my lovely resilient scheme falls down when you have a protocol 
that switches from line-oriented to byte-oriented partway through, such as
HTTP.
 2007-01-12 18:09:14 +00:00
Michael Brown ad22cccc09 No need to maintain a received byte count; we always fill in sequential 
order so we can just use buffer->fill.
 2007-01-12 17:16:46 +00:00
Michael Brown 996b091b50 Added generic line-buffering code (a la stdio) 2007-01-12 17:08:37 +00:00
Michael Brown e2c0055e23 Let ifmgmt.c take care of calling efree(), since it's the once which 
took out the contract to eventually call efree() when it called fetch().

Maintain the most recently loaded image at the start of the list, so that
imgautoselect() will pick it.
 2007-01-12 09:46:10 +00:00
Michael Brown 2be2f3b205 Rearrange struct image to reflect usage of the fields 2007-01-12 08:58:16 +00:00
Michael Brown 48e0fc3447 API change: the raw image will no longer be (hypothetically) discarded 
after a call to load().
 2007-01-12 08:15:25 +00:00
Michael Brown 6fdc6c81a6 Force probing of multiboot before ELF. 2007-01-12 08:10:35 +00:00
Michael Brown 475d6d1f7c fetch() now knows nothing about struct image; it simply loads a file and 
returns the allocated buffer.
 2007-01-12 08:02:27 +00:00
Michael Brown 742f242863 Add free_image 2007-01-12 06:26:59 +00:00
Michael Brown b9fea9cbac Added IMAGE_LOADED flag and find_image() 2007-01-12 06:03:02 +00:00
Michael Brown e96041872e Added missing declaration. 2007-01-12 05:27:02 +00:00
Michael Brown 9debfed07a Place command-line inline, to save on memory allocation hassles. 2007-01-12 05:26:19 +00:00
Michael Brown 29dadc5ec6 Build automatically expanding buffers from struct buffer and erealloc(). 2007-01-12 03:51:04 +00:00
Michael Brown 45ec9c907e First version of an external memory allocator (not tested) 2007-01-12 03:15:29 +00:00
Michael Brown 859da6bd32 Allow external code to update hidden memory regions. 2007-01-12 03:13:04 +00:00
Michael Brown 2c66588f3e Add UNULL 2007-01-12 01:40:12 +00:00
Michael Brown f59ad50504 Provide registration mechanism for loaded images, so that we can e.g. 
refer to them by name from the command line, or build them into a
multiboot module list.

Use setting image->type to disambiguate between "not my image" and "bad
image"; this avoids relying on specific values of the error code.
 2007-01-11 23:43:29 +00:00
Michael Brown c468c68661 Add command line that can be passed to executed images. 2007-01-11 21:19:29 +00:00
Michael Brown 819cd3f41c Limit -ENOEXEC to mean "this is not in my format". 2007-01-11 17:06:25 +00:00
Michael Brown c810baad37 Use generic "struct image" rather than "struct elf". 2007-01-11 16:10:32 +00:00
Michael Brown c6c63d954d Rename "image" field to "data", because "image->image" is just confusing. 2007-01-11 16:07:30 +00:00
Michael Brown 4fc9333159 Move include/image.h to include/gpxe/image.h 2007-01-11 16:04:36 +00:00
Michael Brown 230f16538f Create include/gpxe/elf.h for the ELF bits that aren't part of the ELF 
standard and so don't belong in include/elf.h
 2007-01-11 15:25:07 +00:00
Michael Brown 0010e10ef3 Update TFTP to use a struct buffer rather than a callback. 
Add debug autocolourisation to TFTP.
 2007-01-11 15:14:54 +00:00
Michael Brown 3634e705b7 Remove osloader.c and replace with a prep_segment() that uses userptr_t 
and get_memmap() in image/segment.c
 2007-01-11 14:32:26 +00:00
Michael Brown c980cdd0aa Move memmap.h out of arch/i386; it no longer contains anything 
architecture-dependent and is needed by the ELF code.
 2007-01-11 14:08:44 +00:00
Michael Brown fbfed96965 buffer.c should be using copy_{to,from}_user, rather than 
copy_{to,from}_phys.
 2007-01-11 05:42:06 +00:00
Michael Brown a3ed0cbbc7 Extract packet-padding login from rtl8139.c to a separate pkbpad.c file. 2007-01-11 05:25:50 +00:00
Michael Brown 6918cf9e9e Change FTP to use a data buffer rather than a callback function. 2007-01-11 04:51:20 +00:00
Michael Brown e2dcd05b67 Update buffer-handling code to enable expandable buffers. 2007-01-11 03:50:47 +00:00
Michael Brown bb2024c6d6 Move include/buffer.h to include/gpxe/buffer.h 2007-01-11 01:47:26 +00:00
Michael Brown d9ba8f790b Add route() function to display routing table. 2007-01-10 20:38:20 +00:00
Michael Brown 1fa5cd0e2b Add find_pci_netdev() 2007-01-10 16:16:05 +00:00
Michael Brown fdc97499bf Add device description fields to struct device. 2007-01-10 15:27:48 +00:00
Michael Brown dad5274522 Add "name" field to struct device to allow human-readable hardware device 
names.

Add "dev" pointer in struct net_device to tie network interfaces back to a
hardware device.

Force natural alignment of data types in __table() macros.  This seems to
prevent gcc from taking the unilateral decision to occasionally increase
their alignment (which screws up the table packing).
 2007-01-10 04:22:09 +00:00
Michael Brown c821a7b20d Add udp_sendto_via() to allow e.g. DHCP to transmit without first having 
to set up dummy routing entries.
 2007-01-10 02:31:38 +00:00
Michael Brown f008b77ba2 Allow an explicit network device to be specified for IP-layer 
transmissions.
 2007-01-10 02:25:11 +00:00
Michael Brown 55e590ab3a Move header file for usr/autoboot.c to include/usr 2007-01-10 02:03:20 +00:00
Michael Brown d24b80acf2 Added network interface management commands 2007-01-10 01:55:07 +00:00
Michael Brown 98b6154c3e Add "name" field to network device, to facilitate netdev commands. 2007-01-09 23:48:18 +00:00
Michael Brown c65fae2475 Add RX quotas to the net device poll() method. This avoids the problem 
of alloc_pkb() exhaustion when e.g. an iSCSI-booted DOS session is left
idle for a long time at the C:\ prompt and builds up a huge packet
backlog.
 2007-01-09 21:47:01 +00:00
Michael Brown 18e5353bed Rename pkb_available() to pkb_tailroom() for consistency with Linux's 
skb_tailroom().  Add pkb_headroom().
 2007-01-09 20:56:31 +00:00
Michael Brown b7fcfe8ece Added net device TX queue; this will be needed to support the PXE UNDI API 
(which will need us to wait for TX completions).

Added debug autocolourisation to netdevice.c
 2007-01-09 20:18:31 +00:00
Michael Brown 76525294ee Clean up connection closing and permanent failure logic. 2007-01-09 04:31:33 +00:00
Michael Brown 79c5f0ba04 Added PCI_BASE_CLASS() macro 2007-01-08 03:32:41 +00:00
Michael Brown 5af4918356 Added support for wildcard device/vendor ID matches 2007-01-08 03:23:38 +00:00
Michael Brown 0c03bb5a9a Make open() and close() an official part of the netdevice API. 
Call netdevice's poll() and transmit() methods only when device is open.
 2007-01-04 04:20:08 +00:00
Michael Brown 7fafa89258 A DHCP session holds a persistent reference to a network device 2007-01-04 03:42:28 +00:00
Michael Brown ac53da1790 Added missing #include 2007-01-04 03:40:07 +00:00
Michael Brown b29861a5aa IPv6 minirouting table entries hold persistent references to net devices. 2007-01-04 03:28:30 +00:00
Michael Brown b22d4405c0 An AoE session holds a persistent reference to a net device. 2007-01-04 03:21:45 +00:00
Michael Brown bdf79ec8dc Use hotplug support to notify persistent reference holders when a 
net_device is unregistered.
 2007-01-04 03:09:28 +00:00
Michael Brown 0063725d28 Minimal hotplug support: provide a facility for notifying persistent 
reference holders that their reference is about to become invalid.
 2007-01-04 03:08:16 +00:00
Michael Brown a0525a4ed3 Verify checksums on the RX datapath. 
Simplify checksum generation on the TX datapath.
 2007-01-03 20:48:52 +00:00
Michael Brown b91b9d3d88 Use whole bytes for the ACKED and RCVD portions of tcp_state; it 
produces slightly smaller code.
 2006-12-30 01:32:22 +00:00
Michael Brown ce9819af27 Redefine TCP state to include "flags that have been sent" rather than 
"flags that are currently being sent".  This allows at least one special
case (checking that we haven't already sent a FIN in tcp_rx_fin()) to be
collapsed.
 2006-12-29 00:44:31 +00:00
Michael Brown 61ed298bc7 Merge changes from mcb-tcp-fixes branch. 2006-12-27 23:09:46 +00:00
Michael Brown a2e3357825 Cannot immediately overwrite the peer address when we parse 
TargetAddress from the login response, because we still need the old
address while we close the connection!
 2006-12-22 12:24:12 +00:00
Michael Brown 66a7ed23cb Make start_timer() and stop_timer() robust against incorrect usage. 2006-12-22 01:35:21 +00:00
Michael Brown 9485478acc ibft_fill_data() prototype change. 2006-12-21 18:42:51 +00:00
Michael Brown ab242a760d Add ability to shut down iSCSI connection 2006-12-21 17:17:47 +00:00
Michael Brown 46c3eeba2a Fix definition of KEY_END 2006-12-20 22:17:44 +00:00
Michael Brown 2ae27f44d9 Add insert/delete and document keys, and documentation. 2006-12-20 22:11:28 +00:00
Michael Brown 96a1a2c6f0 Key definitions 2006-12-20 21:53:07 +00:00
Michael Brown cbeec25662 settings_ui() now returns a status code. 2006-12-20 11:42:48 +00:00
Michael Brown 84202d89f0 Split the (quick hack) boot logic out from main.c to autoboot.c, add a 
"boot" command to attempt booting from within the command shell, fall back
to shell if boot fails for any reason.
 2006-12-20 07:04:08 +00:00
Michael Brown 8f9336e0c1 Add "config" command to access config UI 2006-12-20 05:37:33 +00:00
Michael Brown b93ff48173 Added descriptive text for settings and setting types, and display it in 
the option config UI.
 2006-12-20 04:58:26 +00:00
Michael Brown 35edecac34 Move {show,set,clear}_setting() to {show,set,clear}_named_setting(). 
Introduce new {show,set,clear}_setting() that take a struct setting *
rather than a const char *.

set_setting() handles calling clear_setting() when appropriate, so that
individual setting types don't have to check for empty strings.
 2006-12-20 04:20:13 +00:00
Michael Brown 84a2b886e1 Split error-message table portions of errno.h out to gpxe/errortab.h 2006-12-20 03:40:48 +00:00
Michael Brown 3e0f7621eb Don't automatically redraw the edit box; this allows better inheritance. 2006-12-20 02:09:41 +00:00
Michael Brown 35dcbfe771 Editable text box widget based on mucurses and edit_string. 2006-12-20 01:40:57 +00:00
Michael Brown 4919646fb9 Separated out (and tidied up) shell banner code 2006-12-20 00:24:13 +00:00
Michael Brown a2c5744daf Minimal shell implementation using readline() and system(). 2006-12-19 23:55:05 +00:00
Michael Brown 66007fa448 Provide an edit history to allow caller to efficiently update display. 2006-12-19 23:24:16 +00:00
Michael Brown 1bc3514bd8 Start of generic editable string support 2006-12-19 19:28:12 +00:00
Michael Brown 8b3a4c9862 Add basic ANSI escape sequence support to BIOS console 2006-12-18 01:19:38 +00:00
Michael Brown 1cd45decc4 Added support for interpreting ANSI escape sequences on behalf of 
non-ANSI-capable consoles.
 2006-12-18 00:01:30 +00:00
Michael Brown a39b111684 Automatically select between the "10" and "16" variants of command set, 
based on the device size.
 2006-12-12 18:54:35 +00:00
Michael Brown 007ca97f25 Added clear_setting() 2006-12-12 15:49:46 +00:00
Michael Brown 72b1629cee Add placeholder ibft.h 2006-12-08 16:16:21 +00:00
Michael Brown f3d817d512 Added execv() and system(). 2006-12-08 01:23:11 +00:00
Michael Brown d2bf7abe75 Added write support for three-wire devices (e.g. the RTL8139 EEPROM) 2006-12-06 19:51:58 +00:00
Michael Brown 89bcb57201 Update ftp.c to work with Nikhil's TCP stack. 
Remove the now-totally-obsolete sockaddr_in field from tcp.h.
 2006-12-05 19:07:47 +00:00
Michael Brown 6a91a03409 Added options listed in 
http://www.microsoft.com/whdc/winlogo/hwrequirements.mspx as required
for iSCSI boot.  Note that options 204-206 are listed in the document

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.
 2006-12-04 18:23:06 +00:00
Michael Brown 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.

 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 c3a4f3c5da Towards an RFC2988-compliant timer. 2006-08-09 15:54:17 +00:00
Marty Connor ee9ae8130a Remove _PROTOCOL macros for gcc 3.2 compatibility 2006-08-09 04:42:14 +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
 2006-08-09 02:56:40 +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.
 2006-08-09 01:24:32 +00:00
Michael Brown 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
Michael Brown 72cd29f13c Added some TFTP definitions for use with the new UDP API. 2006-08-08 22:01:16 +00:00
Michael Brown 68e33224ef gcc3 compatibility: removed ARP_NET_PROTOCOL(). 2006-08-08 17:44:25 +00:00
Nikhil Chandru Rao d2bdf81505 Removed some bugs in TCP 2006-08-08 03:42:30 +00:00
Nikhil Chandru Rao cb42e573a0 Added retransmissions to TCP 2006-08-07 18:52:26 +00:00
Michael Brown 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.)
 2006-08-02 23:08:10 +00:00
Michael Brown 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.
 2006-08-02 00:02:21 +00:00
Nikhil Chandru Rao 9225f4edac TCP support 2006-08-01 20:46:50 +00:00

Michael Brown 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
Michael Brown 3a0e293123 Renamed tcpip_if.[ch] to tcpip.[ch] 2006-08-01 14:18:09 +00:00
Michael Brown b26806cf18 Add dhcp_snprintf() for extracting DHCP string options. 2006-07-20 14:13:11 +00:00
Michael Brown 7ca8bcd98c Print out the lease time, just to show how easy it is. 2006-07-20 03:02:34 +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
Michael Brown 7ca1bb0fbe Now successfully negotiates the whole DHCPDISCOVER/OFFER/REQUEST/ACK 
cycle.  :)
 2006-07-20 02:19:06 +00:00
Michael Brown 2c0eb6eb1d Correct TCP/IP checksum generation. 2006-07-19 23:38:05 +00:00
Nikhil Chandru Rao 13dbf5494d Minor edits 2006-07-19 21:05:58 +00:00
Michael Brown 224529d8dd Now capable of sending what, to me, looks like a valid DHCPDISCOVER 
(apart from the bad UDP checksum).
 2006-07-19 20:50:50 +00:00
Michael Brown 6858b14a34 Add pkb_available() 2006-07-19 18:16:48 +00:00
Michael Brown 6d9d48537e Added some debug messages and DHCP test code 2006-07-19 17:49:31 +00:00
Michael Brown 317b962b65 Proof of concept: transmit a single DHCPDISCOVER and dump out any 
parsed DHCP responses.
 2006-07-19 17:32:13 +00:00
Michael Brown 76070cd226 Added missing prototype 2006-07-19 17:29:18 +00:00
Michael Brown bf0cdd42cf Add some DHCP options that we are likely to use 2006-07-19 17:00:32 +00:00
Michael Brown e0668ad8df Correct typo 2006-07-19 16:58:44 +00:00
