Brad Fitzpatrick	da8def8e13	all: remove old +build tags The //go:build syntax was introduced in Go 1.17: https://go.dev/doc/go1.17#build-lines gofmt has kept the +build and go:build lines in sync since then, but enough time has passed. Time to remove them. Done with: perl -i -npe 's,^// \+build.*\n,,' $(git grep -l -F '+build') Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Andrew Dunham	9b77ac128a	wgengine: print in-flight operations on watchdog trigger (#5447 ) In addition to printing goroutine stacks, explicitly track all in-flight operations and print them when the watchdog triggers (along with the time they were started at). This should make debugging watchdog failures easier, since we can look at the longest-running operation(s) first.

Brad Fitzpatrick	a12aad6b47	all: convert more code to use net/netip directly perl -i -npe 's,netaddr.IPPrefixFrom,netip.PrefixFrom,' $(git grep -l -F netaddr.) perl -i -npe 's,netaddr.IPPortFrom,netip.AddrPortFrom,' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPrefix,netip.Prefix,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPort,netip.AddrPort,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IP\b,netip.Addr,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPv6Raw\b,netip.AddrFrom16,g' $(git grep -l -F netaddr. ) goimports -w . Then delete some stuff from the net/netaddr shim package which is no longer neeed.

Brad Fitzpatrick	41fd4eab5c	envknob: add new package for all the strconv.ParseBool(os.Getenv(..)) A new package can also later record/report which knobs are checked and set.

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
Naman Sood	420c7a35e2	wgengine/netstack: use tailscale IPs instead of a hardcoded one (#1131 ) Signed-off-by: Naman Sood <mail@nsood.in>	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. Fixes #387 (Don't hard-code the DERP map) Updates #388 (Add DERP region support) Fixes #399 (wgengine: flaky tests) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago

David Anderson	72cae5504c	wgengine: generate and plumb router.Settings in from ipn.
