Brad Fitzpatrick	e8ae355bb8	ipn: delete domainsForProxying, require explicit DNS search domains (mapver 9) (#1078 ) Previously the client had heuristics to calculate which DNS search domains to set, based on the peers' names. Unfortunately that prevented us from doing some things we wanted to do server-side related to node sharing. So, bump MapRequest.Version to 9 to signal that the client only uses the explicitly configured DNS search domains and doesn't augment it with its own list.

Brad Fitzpatrick	741c513e51	wgengine/tsdns: fix error response marshaling, improve bad query logs Updates #995 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Josh Bleecher Snyder	1fd10061fd	wgengine/tsdns: delegate bonjour service rdns requests While we're here, parseQuery into a plain function. This is helpful for fuzzing. (Which I did a bit of. Didn't find anything.) And clean up a few minor things. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Dmytro Shynkevych	34a7e7c12b	tsdns: be more strict with type validation. Previously, a type AAAA query would be answered with an A record if only an IPv4 address was available. This is irrelevant for us while we only use IPv4, but it will be a bug one day, so it's worth being precise about semantics. Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Dmytro Shynkevych	bc34788e65	tsdns: fix accidental rejection of all non-{A, AAAA} questions. This is a bug introduced in `a903d6c2ed`. Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Dmytro Shynkevych	a903d6c2ed	tailcfg, tsdns: derive root domains from list of nodes (#708 ) Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Dmytro Shynkevych	6c71e5b851	tsdns: copy name when loewrcasing. The previous approach modifies name in-place in the request slice to avoid an allocation. This is incorrect: the question section of a DNS request must be copied verbatim, without any such modification. Software may rely on it (we rely on other resolvers doing it it in tsdns/forwarder).

Dmytro Shynkevych	1886dfdca3	tsdns: lowercase the name in parseQuery. Domains in DNS should be case-insensitive. Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago

Dmytro Shynkevych	67ebba90e1	tsdns: dual resolution mode, IPv6 support (#526 ) This change adds to tsdns the ability to delegate lookups to upstream nameservers. This is crucial for setting Magic DNS as the system resolver. Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
