u-root -> dhcp -> u-root is the circular dependency. Which is fine, except we messed up modules in u-root big time. We need to break the circular dep for now. Signed-off-by: Chris Koch <chrisko@google.com>

2021-03-06Pad packets after the 'end' option to be more conformantMarcel Moolenaar
RFC 2131 gives two examples of padding in section 4.1. For both the examples, the 'end' option preceeds the padding with the 'pad' option. These examples relate to overloading pre-defined fields for options, not padding the packet for a minimal size. Older versions of the U-Boot firmware support DHCP, but do not expect the 'pad' option. The firmware logs the following warning for each occurence: *** Unhandled DHCP Option in OFFER/ACK: 0 This warning disappears when the 'end' option preceeds the 'pad' option.

2020-09-16Add Additional IANA Architecture TypesBenjamin S. Allen
Adds the additional architecture types as defined by IANA http://www.iana.org/assignments/dhcpv6-parameters/dhcpv6-parameters.xhtml#processor-architecture. Note, RFC4578 errata, https://www.rfc-editor.org/errata_search.php?rfc=4578 "The values for EFI BC and EFI x86-64 should be swapped. UEFI implementations use value 7 to report EFI x86-64, not value 9." IANA's list also agrees with this swap. Thus I've swapped these values here to match. I took some liberty with the new architecture's mnemonic names compared to the descriptions from IANA. This was an attempt to standardize wording, capitalization, and match the existing style.

2020-07-10netconf: apply v6 addresses as /128Chris Koch
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=684009 "Note that the dhcpv6 protocol doesn't have an option for a netmask. So it is always /128 and routing is left to icmpv6 router advertisements." RFC 5942 is a good read here as well: An address could be acquired through the DHCPv6 identity association for non- temporary addresses (IA_NA) option from [RFC3315] (which does not include a prefix length), or through manual configuration (if no prefix length is specified). The host incorrectly assumes an invented prefix is on-link. This invented prefix typically is a /64 that was written by the developer of the operating system network module API to any IPv6 application as a "default" prefix length when a length isn't specified. As DHCP developers, we *HAVE* to assume that no prefix is on-link. The correct way to do that is to specify the netmask as /128. The kernel will RA/RS their way around to figure out what prefixes are indeed on-link. Signed-off-by: Chris Koch <chrisko@google.com>
