Brad Fitzpatrick	e74d37d30f	net/dns{,/resolver}: quiet DNS output logging It was a huge chunk of the overall log output and made debugging difficult. Omit and summarize the spammy *.arpa parts instead. Fixes tailscale/corp#2066 (to which nobody had opinions, so)	3 years ago
Brad Fitzpatrick	45e64f2e1a	net/dns{,/resolver}: refactor DNS forwarder, send out of right link on macOS/iOS Fixes #2224 Fixes tailscale/corp#2045 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
David Crawshaw	297b3d6fa4	staticcheck.conf: turn off noisy lint errors Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	4 years ago
David Anderson	e2dcf63420	net/dns: replace AuthoritativeSuffixes with nil Route entries. This leads to a cleaner separation of intent vs. implementation (Routes is now the only place specifying who handles DNS requests), and allows for cleaner expression of a configuration that creates MagicDNS records without serving them to the OS. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	6690f86ef4	net/dns: always offer MagicDNS records at 100.100.100.100. Fixes #1886. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Josh Bleecher Snyder	25df067dd0	all: adapt to opaque netaddr types This commit is a mishmash of automated edits using gofmt: gofmt -r 'netaddr.IPPort{IP: a, Port: b} -> netaddr.IPPortFrom(a, b)' -w . gofmt -r 'netaddr.IPPrefix{IP: a, Port: b} -> netaddr.IPPrefixFrom(a, b)' -w . gofmt -r 'a.IP.Is4 -> a.IP().Is4' -w . gofmt -r 'a.IP.As16 -> a.IP().As16' -w . gofmt -r 'a.IP.Is6 -> a.IP().Is6' -w . gofmt -r 'a.IP.As4 -> a.IP().As4' -w . gofmt -r 'a.IP.String -> a.IP().String' -w . And regexps: \w(.)\.Port = (.) -> $1 = $1.WithPort($2) \w(.)\.IP = (.) -> $1 = $1.WithIP($2) And lots of manual fixups. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

David Anderson	158328ba24	net/dns: remove ForceSplitDNSForTesting. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	bb0710d51d	net/dns: add debugging traces to DNS manager selection on linux. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	854d5d36a1	net/dns: return error from NewOSManager, use it to initialize NM. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	1a371b93be	util/dnsname: add FQDN type, use throughout codebase. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	2685260ba1	net/dns: add temporary fallback to quad-9 resolver for split-DNS testing. This allows split-DNS configurations to not break clients on OSes that haven't yet been ported to understand split DNS, by falling back to quad-9 as a global resolver when handed an "impossible to implement" split-DNS config. Part of #953. Needs to be removed before shipping 1.8. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	b9e194c14b	net/dns: add missing FQDN qualification. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	b74a8994ca	net/dns: make FQDN dot style consistent in more places. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	4a64d2a603	net/dns: some post-review cleanups. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	720c1ad0f0	net/dns: insert OS base config when emulating split DNS. Part of #953. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	da4cc8bbb4	net/dns: handle all possible translations of high-level DNS config. With this change, all OSes can sort-of do split DNS, except that the default upstream is hardcoded to 8.8.8.8 pending further plumbing. Additionally, Windows 8-10 can do split DNS fully correctly, without the 8.8.8.8 hack. Part of #953. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	e0e677a8f6	net/dns: split out search domains and match domains in OSConfig. It seems that all the setups that support split DNS understand this distinction, and it's an important one when translating high-level configuration. Part of #953. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	c16a926bf2	net/dns: set OSConfig.Primary. OS implementations are going to support split DNS soon. Until they're all in place, hardcode Primary=true to get the old behavior. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	b2a597b288	net/dns: rename Set to SetDNS in OSConfigurator. wgengine/router.CallbackRouter needs to support both the Router and OSConfigurator interfaces, so the setters can't both be called Set. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	7d84ee6c98	net/dns: unify the OS manager and internal resolver. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	6a206fd0fb	net/dns: rename impl to os. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	4c61ebacf4	wgengine: move DNS configuration out of wgengine/router. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	befd8e4e68	net/dns: replace managerImpl with OSConfigurator in code. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	8af9d770cf	net/dns: rename Config to OSConfig. Making way for a new higher level config struct. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	fcfc0d3a08	net/dns: remove ManagerConfig, pass relevant args directly. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	95470c3448	net/dns: remove Cleanup manager parameter. It's only use to skip some optional initialization during cleanup, but that work is very minor anyway, and about to change drastically. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	cf361bb9b1	net/dns: remove PerDomain from Config. It's currently unused, and no longer makes sense with the upcoming DNS infrastructure. Keep it in tailcfg for now, since we need protocol compat for a bit longer. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	f77ba75d6c	wgengine/router: move DNS cleanup into the DNS package. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	9f7f2af008	wgengine/router/dns: move to net/dns. Preparation for merging the APIs and whatnot. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
