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	18 년 전
Michael Brown	d1a123b1f4	Added TFTP test code (currently just dumps file to console).	18 년 전
Michael Brown	3611cb17b7	Initial (untested) implementation of TFTP over the new UDP API.	18 년 전
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.	18 년 전
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.	18 년 전
Michael Brown	ae277992c2	Request bootfile name; it doesn't seem to be automatically supplied by all servers.	18 년 전
Michael Brown	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.	18 년 전
Michael Brown	6a0b4c9772	Free up any allocated options if we fail	18 년 전
Michael Brown	764cb41456	Document memory ownership.	18 년 전
Michael Brown	7ca1bb0fbe	Now successfully negotiates the whole DHCPDISCOVER/OFFER/REQUEST/ACK cycle. :)	18 년 전
Michael Brown	30d9bcdc6e	Rename unwieldy function	18 년 전
Michael Brown	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.	18 년 전
Michael Brown	881b90e82c	Packets without a DHCP_MESSAGE_TYPE option are probably just BOOTP packets.	18 년 전
Michael Brown	0768670fd8	udp_open() takes ports in network-endian order.	18 년 전
Michael Brown	224529d8dd	Now capable of sending what, to me, looks like a valid DHCPDISCOVER (apart from the bad UDP checksum).	18 년 전
Michael Brown	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.	18 년 전
Michael Brown	6d9d48537e	Added some debug messages and DHCP test code	18 년 전
Michael Brown	317b962b65	Proof of concept: transmit a single DHCPDISCOVER and dump out any parsed DHCP responses.	18 년 전
Michael Brown	16fc9858db	Beginnings of DHCP protocol implementation	18 년 전
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.	18 년 전
Michael Brown	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.	18 년 전
Michael Brown	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.	18 년 전
Michael Brown	12da7ea475	Add (untested) code for parsing a received DHCP packet and constructing a DHCP options block from the contents.	18 년 전
