IPv6 DNS fixes

ipv6: remove obsolete three-server DNS limit

2026-10-05T23:19:48+00:00

The legacy limit matches RFC 6106's recommendation that hosts treat three learned RDNSS addresses as sufficient. That was host-side repository guidance, not a limit in the RADIUS, DHCPv6, or RDNSS encodings. RFC 8106 obsoletes RFC 6106 and explicitly removes the recommendation to limit learned RDNSS addresses to three, leaving the number to local policy. It instead recommends the ability to store at least three addresses when DNS information comes from multiple sources. Store both configured and per-session servers in reusable contiguous arrays. Start with a four-address, 64-byte allocation, grow geometrically, retain capacity across reload or reauthorization, and free session storage only at teardown. Bound advertised lists by actual DHCPv6 and router-advertisement packet space. Warn when servers have to be dropped for lack of room, as the fixed limit used to, skip the DNS search list rather than write it past the end of a full advertisement, and drop the stale three-server wording from the [ipv6-dns] documentation.

ipv6: use a dedicated type for per-session DNS

2026-10-05T23:18:41+00:00

DNS-Server-IPv6-Address carries a full IPv6 address, so storing it in ipv6db_addr_t also carried an unused prefix length and flags. Introduce dedicated DNS list and address types so the representation matches the data.

ipv6_nd: do not overrun the advertisement buffer with prefix information

2026-10-05T23:18:41+00:00

The prefix information options are written into a fixed 1024 byte pool buffer with no bound at all, one 32 byte option per address on the session. A session carrying more than about thirty addresses therefore writes past the end of the buffer. Skip the prefix information of the addresses which no longer fit and warn about them. The loop also installs the addresses on the interface, so keep doing that regardless of how much room is left in the advertisement.
