KevinLiang10	8d7b78f3f7	net/dns/publicdns: remove additional information in DOH URL passed to IPv6 address generation for controlD. This commit truncates any additional information (mainly hostnames) that's passed to controlD via DOH URL in DoHIPsOfBase. This change is to make sure only resolverID is passed to controlDv6Gen but not the additional information.

Kevin Liang	7f83f9fc83	Net/DNS/Publicdns: update the IPv6 range that we use to recreate route endpoint for control D In this commit I updated the Ipv6 range we use to generate Control D DOH ip, we were using the NextDNSRanges to generate Control D DOH ip, updated to use the correct range.

James Tucker	1c88a77f68	net/dns/publicdns: update Quad9 addresses and references One Quad9 IPv6 address was incorrect, and an additional group needed adding. Additionally I checked Cloudflare and included source reference URLs for both. Updates #cleanup Signed-off-by: James Tucker <james@tailscale.com>	1 year ago
James Tucker	4c693d2ee8	net/dns/publicdns: update Mullvad DoH server list The following IPs are not used anymore: 193.19.108.2 and 193.19.108.3. All of the servers are now named consistently under dns.mullvad.net. Several new servers were added. https://mullvad.net/en/help/dns-over-https-and-dns-over-tls/ Updates #5416 Updates #9345 Signed-off-by: James Tucker <james@tailscale.com>	1 year ago

Brad Fitzpatrick	b1248442c3	all: update to Go 1.20, use strings.CutPrefix/Suffix instead of our fork Updates #7123 Updates #5309 Change-Id: I90bcd87a2fb85a91834a0dd4be6e03db08438672 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Will Norris	71029cea2d	all: update copyright and license headers This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
Brad Fitzpatrick	bb7be74756	net/dns/publicdns: permit more NextDNS profile bits in its IPv6 suffix I brain-o'ed the math earlier. The NextDNS prefix is /32 (actually /33, but will guarantee last bit is 0), so we have 128-32 = 96 bits (12 bytes) of config/profile ID that we can extract. NextDNS doesn't currently use all those, but might. Updates #2452 Change-Id: I249bd28500c781e45425fd00fd3f46893ae226a2 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	708b7bff3d	net/dns/publicdns: also support NextDNS DoH query parameters The plan has changed. Doing query parameters rather than path + heades. NextDNS added support for query parameters. Updates #2452 Change-Id: I4783c0a06d6af90756d9c80a7512644ba702388c Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

Brad Fitzpatrick	58abae1f83	net/dns/{publicdns,resolver}: add NextDNS DoH support NextDNS is unique in that users create accounts and then get user-specific DNS IPs & DoH URLs. For DoH, the customer ID is in the URL path. For IPv6, the IP address includes the customer ID in the lower bits. For IPv4, there's a fragile "IP linking" mechanism to associate your public IPv4 with an assigned NextDNS IPv4 and that tuple maps to your customer ID. We don't use the IP linking mechanism. Instead, NextDNS is DoH-only. Which means using NextDNS necessarily shunts all DNS traffic through 100.100.100.100 (programming the OS to use 100.100.100.100 as the global resolver) because operating systems can't usually do DoH themselves. Once it's in Tailscale's DoH client, we then connect out to the known NextDNS IPv4/IPv6 anycast addresses. If the control plane sends the client a NextDNS IPv6 address, we then map it to the corresponding NextDNS DoH with the same client ID, and we dial that DoH server using the combination of v4/v6 anycast IPs.

Nahum Shalman	214242ff62	net/dns/publicdns: Add Mullvad DoH See https://mullvad.net/en/help/dns-over-https-and-dns-over-tls/ The Mullvad DoH servers appear to only speak HTTP/2 and the use of a non-nil DialContext in the http.Transport means that ForceAttemptHTTP2 must be set to true to be able to use them.
