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	748670f1e9	net/dns: fix typo in docstring. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	a39d2403bc	net/dns: disable NetworkManager and resolved configurators temporarily. They need some rework to do the right thing, in the meantime the direct and resolvconf managers will work out. The resolved implementation was never selected due to control-side settings. The networkmanager implementation mostly doesn't get selected due to unforeseen interactions with `resolvconf` on many platforms. Both implementations also need rework to support the various routing modes they're capable of. 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	077d4dc8c7	net/dns: add an OSConfigurator interface. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	6ad44f9fdf	wgengine: take in dns.Config, split out to resolver.Config and dns.OSConfig. Stepping stone towards having the DNS package handle the config splitting. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	2edb57dbf1	net/dns: add new Config that captures tailscale+OS DNS config. 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	0ca04f1e01	net/dns: put noop.go back, limit with build tags for staticcheck. 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	9f105d3968	net/dns/resolver: teach the forwarder to do per-domain routing. Given a DNS route map, the forwarder selects the right set of upstreams for a given name. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	90f82b6946	net/dns/resolver: add live reconfig, plumb through to ipnlocal. The resolver still only supports a single upstream config, and ipn/wgengine still have to split up the DNS config, but this moves closer to unifying the DNS configs. As a handy side-effect of the refactor, IPv6 MagicDNS records exist now. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	caeafc4a32	net/dns/resolver: fix package docstring. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	dbe4f6f42d	net/dns/resolver: unexport Resolve and ResolveReverse. They're only used internally and in tests, and have surprising semantics in that they only resolve MagicDNS names, not upstream resolver queries. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	cdeb8d6816	net/dns/resolver: fix staticcheck error. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

Denton Gentry	09148c07ba	interfaces: check correct error /proc/net/route wrap io.EOF if we hit https://github.com/google/gvisor/issues/5732 Check for the correct err. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
Denton Gentry	a9745a0b68	interfaces: try larger read from /proc/net/route Work around https://github.com/google/gvisor/issues/5732 by trying to read /proc/net/route with a larger bufsize if it fails the first time. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
Denton Gentry	54ba6194f7	interfaces: allow IPv6 ULA as a valid address. IPv6 Unique Local Addresses are sometimes used with Network Prefix Translation to reach the Internet. In that respect their use is similar to the private IPv4 address ranges 10/8, 172.16/12, and 192.168/16. Treat them as sufficient for AnyInterfaceUp(), but specifically exclude Tailscale's own IPv6 ULA prefix to avoid mistakenly trying to bootstrap Tailscale using Tailscale. This helps in supporting Google Cloud Run, where the addresses are 169.254.8.1/32 and fddf:3978:feb1:d745::c001/128 on eth1. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago

Brad Fitzpatrick	41e4e02e57	net/{packet,tstun}: send peerapi port in TSMP pongs For discovery when an explicit hostname/IP is known. We'll still also send it via control for finding peers by a list. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	25e0bb0a4e	net/tstun: rename wrap_windows.go to tun_windows.go. The code has nothing to do with wrapping, it's windows-specific driver initialization code. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	22d53fe784	net/tstun: document exported function. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	016de16b2e	net/tstun: rename TUN to Wrapper. The tstun packagen contains both constructors for generic tun Devices, and a wrapper that provides additional functionality. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

David Anderson	018200aeba	net/tstun: rename from net/tun. We depend on wireguard-go/tun, identical leaf packages can be confusing in code. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	44d9929208	wgengine: remove Config.TUNName, require caller to create device. Also factors out device creation and associated OS workarounds to net/tun. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	7f174e84e6	net/interfaces: remove mutating methods, add EqualFiltered instead Now callers (wgengine/monitor) don't need to mutate the state to remove boring interfaces before calling State.Equal. Instead, the methods to remove boring interfaces from the State are removed, as is the reflect-using Equal method itself, and in their place is a new EqualFiltered method that takes a func predicate to match interfaces to compare. And then the FilterInteresting predicate is added for use with EqualFiltered to do the job that that wgengine/monitor previously wanted. Now wgengine/monitor can keep the full interface state around, including the "boring" interfaces, which we'll need for peerapi on macOS/iOS to bind to the interface index of the utunN device. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	7dc88e4c1e	net/interfaces: track more interface metadata in State We have it already but threw it away. But macOS/iOS code will be needing the interface index, so hang on to it. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
