Maisem Ali	6fecc16c3b	ipn/ipnlocal: do not process old status messages received out of order When `setWgengineStatus` is invoked concurrently from multiple goroutines, it is possible that the call invoked with a newer status is processed before a call with an older status. e.g. a status that has endpoints might be followed by a status without endpoints. This causes unnecessary work in the engine and can result in packet loss. This patch adds an `AsOf time.Time` field to the status to specifiy when the status was calculated, which later allows `setWgengineStatus` to ignore any status messages it receives that are older than the one it has already processed.

Brad Fitzpatrick	34d2f5a3d9	tailcfg: add Endpoint, EndpointType, MapRequest.EndpointType Track endpoints internally with a new tailcfg.Endpoint type that includes a typed netaddr.IPPort (instead of just a string) and includes a type for how that endpoint was discovered (STUN, local, etc). Use []tailcfg.Endpoint instead of []string internally. At the last second, send it to the control server as the existing []string for endpoints, but also include a new parallel MapRequest.EndpointType []tailcfg.EndpointType, so the control server can start filtering out less-important endpoint changes from new-enough clients. Notably, STUN-discovered endpoints can be filtered out from 1.6+ clients, as they can discover them amongst each other via CallMeMaybe disco exchanges started over DERP. And STUN endpoints change a lot, causing a lot of MapResposne updates. But portmapped endpoints are worth keeping for now, as they they work right away without requiring the firewall traversal extra RTT dance. End result will be less control->client bandwidth. (despite negligible increase in client->control bandwidth) Updates tailscale/corp#1543 Signed-off-by: Brad Fitzpatrick <bradfitz@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	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

Brad Fitzpatrick	ffa70a617d	wgengine{,/monitor}: restore Engine.LinkChange, add Mon.InjectEvent The Engine.LinkChange method was recently removed in `e3df29d488` while misremembering how Android's link state mechanism worked. Rather than do some last minute rearchitecting of link state on Android before Tailscale 1.6, restore the old Engine.LinkChange hook for now so the Android client doesn't need any changes. But change how it's implemented to instead inject an event into the link monitor. Fixes #1427 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	e3df29d488	wgengine{,/monitor}: move interface state fetching/comparing to monitor Gets it out of wgengine so the Engine isn't responsible for being a callback registration hub for it. This also removes the Engine.LinkChange method, as it's no longer necessary. The monitor tells us about changes; it doesn't seem to need any help. (Currently it was only used by Swift, but as of `14dc790137` we just do the same from Go) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Josh Bleecher Snyder	fe7c3e9c17	all: move wgcfg from wireguard-go This is mostly code movement from the wireguard-go repo. Most of the new wgcfg package corresponds to the wireguard-go wgcfg package. wgengine/wgcfg/device{_test}.go was device/config{_test}.go. There were substantive but simple changes to device_test.go to remove internal package device references. The API of device.Config (now wgcfg.DeviceConfig) grew an error return; we previously logged the error and threw it away. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

Brad Fitzpatrick	587bdc4280	ipn, wgengine: disable subnet routes if network has PAC configuration Not configurable yet. Updates tailscale/corp#653 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	9b07517f18	wgengine: add Engine.SetLinkChangeCallback Start of making the IPN state machine react to link changes and down its DNS & routes if necessary to unblock proxy resolution (e.g. for transitioning from public to corp networks where the corp network has mandatory proxies and WPAD PAC files that can't be resolved while using the DNS/routes configured previously) This change should be a no-op. Just some callback plumbing.	4 years ago

Brad Fitzpatrick	e6b84f2159	all: make client use server-provided DERP map, add DERP region support Instead of hard-coding the DERP map (except for cmd/tailscale netcheck for now), get it from the control server at runtime. And make the DERP map support multiple nodes per region with clients picking the first one that's available. (The server will balance the order presented to clients for load balancing) This deletes the stunner package, merging it into the netcheck package instead, to minimize all the config hooks that would've been required. Also fix some test flakes & races.
