Does odhcpd support temporary addresses?

Installing and Using OpenWrt

Hi!

I just need confirmation that the DHCPv6 server (odhcpd) only supports non-temporary addresses (IA_NA) and prefix delegation (IA_PD).

Temporary addresses are client setting, indifferent from servers point of view.

This is not what is written in the RFC 8415.

6.5. DHCP for Temporary Addresses

Temporary addresses were originally introduced to avoid privacy concerns with stateless address autoconfiguration, which based 64 bits of the address on the EUI-64 (see [RFC4941]. They were added to DHCP to provide complementary support when stateful address assignment is used.

Temporary address assignment works mostly like non-temporary address assignment (see Section 6.2); however, these addresses are generally intended to be used for a short period of time and not to have their lifetimes extended, though they can be if required.

This option is defined in the DHCPv6 standard (see 21.5. Identity Association for Temporary Addresses Option).

Please check the github openwrt/odhcpd: This repository is a mirror of https://git.openwrt.org/?p=project/odhcpd.git. Pull requests will be accepted which will be merged in odhcpd.git

Thanks! I have partially read odhcpd's sources. I didn't find anything about the IA_TA (Identity Association Temporary Address). It would have made my life easier to specify in the README that odhcpd did not support this option.

Probably add to readme at the same pr that it sends email and prints pdfs [/sarcasm]
