From https://tools.ietf.org/html/rfc5970#section-6: "The following options have been assigned by the IANA from the option number space defined in Section 24 of the DHCPv6 RFC [RFC3315]."

So, I would suggest that https://www.iana.org/assignments/dhcpv6-parameters/dhcpv6-parameters.xhtml#processor-architecture is probably a good source.

Yes, this is DHCPv6, not DHCPv4, but no one appears to have cared enough to supersede rfc4578 with an updated version.

Having reached that conclusion, I peeked in UEFI 2.8. In Table 210. PXE Tag Definitions for EFI, the description for Client System Architecture is:

Type (2) Type is a two byte, network order, field that identifies the processor and programming environment of the client system. For the various architecture type encodings, see the table "Processor Architecture Types" at “Links to UEFI-Related Documents” (http://uefi.org/uefi) under the heading “Processor Architecture Types

That link in fact points to the IANA page again.

QUESTION

Filename string in DHCP/BOOTP/TFTP Read Request presenting extra characters

Asked 2019-Mar-01 at 00:26

While building a basic Windows Image deployment solution (using WinPE and custom applications built in C#), I came across a problem of 2 Computers not being on the same subnet/IP segment (no static IP Address or DHCP Servers & DNS/Routing tables). To combat this I have written a basic but successful DHCP solution and extended it to TFTP for remote boot in C#.

This application was implemented using guidance in RFCs 1350, 4578, and has the beginnings of negotiation referenced in RFC 2347. I have managed to write a routine that sends the requested files to the remote application.

I have utilized the Wireshark application to examine my outgoing messages, and found that the DHCPOFFER and DHCPACK responses were malformed. These have been corrected, but leaving me with an issue with the TFTP implementation.

The client machine is requesting the provided boot file name, but appending extra bytes to the name before the 0 byte signifying the end of the file name string. Please see below excerpt from my code for extracting the file name from the TFTP Read Request (RRQ) message:

I have had to utilize the string.SubString() method:

string filestring = Encoding.ASCII.GetString(tmpbytes); int pos = filestring.IndexOf("?"); filestring = filstring.SubString(0, pos-1);

to remove the unwanted character from tmpbytes array.

Options 93, 94 & 97 are now passed back in the DHCPOFFER message post options requested. Both DHCP and TFTP implementation now working as expected.
