e74e20cb55 Remove the static IP address hack from netdevice.c, and change the
default test to the DHCP test.

00a1f000b1 Added dhcp_ipv4_option() and friends.

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).

a38010fb0e Make udp_send() call udp_sendto(), rather than vice-versa. 2006-07-19 20:38:49 +00:00

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.

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.

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.

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.

DHCP options block from the contents.

51d62d1a3c Provide a mechanism for returning the encapsulator as well as the
encapsulated option; this will be needed for modifications to the options
