We have published an IETF I-D that proposes an improved handling of IPv6 atomic fragments (IPv6 fragments that have an offset of 0, and MF=0). The I-D is available here: The aforementioned behaviour eliminates fragmentation-based attacks against traffic that employs atomic fragments, and has already been implemented by OpenBSD.
