Folks,

I did a patch to the Linux kernel (net-next) to implement the upcoming
revision of RFC4941 (https://tools.ietf.org/html/draft-ietf-6man-rfc4941bis)

The patch is available here:

and should be applied against net-next:
https://www.gont.com.ar/code/fgont-patch-linux-net-next-rfc4941bis.txt

If you try it, there's two things that would become evident:

1) The valid lifetime of temporary addresses has been reduce to two
days. As a result, you will see at most two concurrent temporary
addresses for each prefix.

2) Different randomized IIDs are employed for each address and prefix,
thus preventing activity correlation among different addresses.

Thanks!

Cheers,
