Michael Brown	f77815f2b1	Kill off hotplug.h and just make net devices normal reference-counted structures. DHCP still broken and #if 0'd out.	vor 18 Jahren
Anselm Martin Hoffmeister	ed7dc02a95	hoffmeis: Preparations for syslog support (LOGSERVER in DHCP, linewise output buffering defintions and the like)	vor 18 Jahren
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.	vor 18 Jahren
Michael Brown	7fafa89258	A DHCP session holds a persistent reference to a network device	vor 18 Jahren
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 but don't seem to be defined anywhere on the web.	vor 18 Jahren
Michael Brown	74c41fac06	Create "username" and "password" DHCP options, ready for placing this information in NVS.	vor 18 Jahren
Michael Brown	cab3f4502b	Correct option number for DHCP_DNS_SERVERS, and add it to the request list.	vor 19 Jahren
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	vor 19 Jahren
Michael Brown	b26806cf18	Add dhcp_snprintf() for extracting DHCP string options.	vor 19 Jahren
Michael Brown	7ca8bcd98c	Print out the lease time, just to show how easy it is.	vor 19 Jahren
Michael Brown	00a1f000b1	Added dhcp_ipv4_option() and friends. Added test code to configure the interface for IPv4 after DHCP.	vor 19 Jahren
Michael Brown	7ca1bb0fbe	Now successfully negotiates the whole DHCPDISCOVER/OFFER/REQUEST/ACK cycle. :)	vor 19 Jahren
Michael Brown	224529d8dd	Now capable of sending what, to me, looks like a valid DHCPDISCOVER (apart from the bad UDP checksum).	vor 19 Jahren
Michael Brown	6d9d48537e	Added some debug messages and DHCP test code	vor 19 Jahren
Michael Brown	317b962b65	Proof of concept: transmit a single DHCPDISCOVER and dump out any parsed DHCP responses.	vor 19 Jahren
Michael Brown	bf0cdd42cf	Add some DHCP options that we are likely to use	vor 19 Jahren
Michael Brown	b8d619e822	Added macros for generating static DHCP options	vor 19 Jahren
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.	vor 19 Jahren
Michael Brown	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.	vor 19 Jahren
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.	vor 19 Jahren
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.	vor 19 Jahren
Michael Brown	12da7ea475	Add (untested) code for parsing a received DHCP packet and constructing a DHCP options block from the contents.	vor 19 Jahren
Michael Brown	19e8b41562	Add code to modify DHCP option values within a block.	vor 19 Jahren
Michael Brown	51d62d1a3c	Provide a mechanism for returning the encapsulator as well as the encapsulated option; this will be needed for modifications to the options block.	vor 19 Jahren
Michael Brown	291f072b82	Add priority mechanism	vor 19 Jahren
Michael Brown	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.)	vor 19 Jahren
