The IESG has received a request from the IPv6 Maintenance WG (6man) to consider the following document: - 'Implications of Oversized IPv6 Header Chains' <draft-ietf-6man-oversized-header-chain-08.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2013-10-16. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The IPv6 specification allows IPv6 header chains of an arbitrary size. The specification also allows options which can in turn extend each of the headers. In those scenarios in which the IPv6 header chain or options are unusually long and packets are fragmented, or scenarios in which the fragment size is very small, the first fragment of a packet may fail to include the entire IPv6 header chain. This document discusses the interoperability and security problems of such traffic, and updates RFC 2460 such that the first fragment of a packet is required to contain the entire IPv6 header chain. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-6man-oversized-header-chain/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-6man-oversized-header-chain/ballot/ No IPR declarations have been submitted directly on this I-D.
