hoffmeis: Preparations for syslog support (LOGSERVER in DHCP, linewise
...
output buffering defintions and the like)

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.

A DHCP session holds a persistent reference to a network device
2007-01-04 03:42:28 +00:00
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
but don't seem to be defined anywhere on the web.

Create "username" and "password" DHCP options, ready for placing this
...
information in NVS.

Correct option number for DHCP_DNS_SERVERS, and add it to the request
...
list.
2006-08-27 01:37:58 +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
2006-08-09 02:56:40 +00:00

Add dhcp_snprintf() for extracting DHCP string options.
2006-07-20 14:13:11 +00:00
7ca8bcd98c
Print out the lease time, just to show how easy it is.
2006-07-20 03:02:34 +00:00

Added dhcp_ipv4_option() and friends.
...
Added test code to configure the interface for IPv4 after DHCP.

Now successfully negotiates the whole DHCPDISCOVER/OFFER/REQUEST/ACK
...
cycle. :)
2006-07-20 02:19:06 +00:00

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
6d9d48537e
Added some debug messages and DHCP test code
2006-07-19 17:49:31 +00:00
317b962b65
Proof of concept: transmit a single DHCPDISCOVER and dump out any
...
parsed DHCP responses.
2006-07-19 17:32:13 +00:00

Add some DHCP options that we are likely to use
2006-07-19 17:00:32 +00:00
b8d619e822
Added macros for generating static DHCP options
2006-07-19 16:16:51 +00:00
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

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.
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

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
19e8b41562
Add code to modify DHCP option values within a block.
2006-07-13 20:49:04 +00:00
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
291f072b82
Add priority mechanism
2006-06-28 13:48:02 +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.)
