Brad Fitzpatrick	3ea6ddbb5f	control/controlbase: use less memory when idle (remove rxState.buf) Uses 4KB less per Conn. Fixes #4113 Change-Id: I38d25b1cf5ecf45423404a330b7ecab79a9fb176 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
James Tucker	445c04c938	wgengine: inject packetbuffers rather than bytes (#4220 ) Plumb the outbound injection path to allow passing netstack PacketBuffers down to the tun Read, where they are decref'd to enable buffer re-use. This removes one packet alloc & copy, and reduces GC pressure by pooling outbound injected packets. Fixes #2741 Signed-off-by: James Tucker <james@tailscale.com>	3 years ago
David Anderson	a09c30aac2	prober: refactor probe state into a Probe struct. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	94aaec5c66	prober: rename Probe to ProbeFunc. Making way for a future Probe struct to encapsulate per-probe state. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	7b4960316b	tsweb: add PrometheusVar, for vars that want to output varz themselves. This enables the infrequent use of more complex Prometheus types, such as timeseries with high/irregular label cardinality, without needing to discover and implement generic abstracted type like LabelMap for each one.

James Tucker	73314009d0	go.mod: bump netstack (#4222 ) Primarily this is for f375784d83852b1e3ff20cc9de0648b3c0cf8525 and the related commits that provide buffer pooling for the endpoint code paths we use. Signed-off-by: James Tucker <james@tailscale.com>	3 years ago

David Anderson	19f61607b6	prober: run all probes once on initial registration. Turns out, it's annoying to have to wait the entire interval before getting any monitorable data, especially for very long interval probes like hourly/daily checks.

Maisem Ali	309c0a13a5	tsweb: add FQDN to Port80Handler to allow HTTPS redirects When the request comes in say over http://mon, the current implementation would rewrite it https://mon which causes the cert validation to fail. This PR keeps the existing behavior intact but also allows passing in a FQDN to the handler to reroute to the correct hostname.

Aaron Klotz	6e91f872af	net/tshttpproxy: ensure we pass the correct flags to WinHttpOpen on Win7 and Win8.0 The best flag to use on Win7 and Win8.0 is deprecated in Win8.1, so we resolve the flag depending on OS version info. Fixes https://github.com/tailscale/tailscale/issues/4201 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	3 years ago
Brad Fitzpatrick	1db46919ab	cmd/tailscaled: make build fail nicely on older Go versions Due to a bug in Go (golang/go#51778), cmd/go doesn't warn about your Go version being older than the go.mod's declared Go version in that case that package loading fails before the build starts, such as when you use packages that are only in the current version of Go, like our use of net/netip. This change works around that Go bug by adding build tags and a pre-Go1.18-only file that will cause Go 1.17 and earlier to fail like: $ ~/sdk/go1.17/bin/go install ./cmd/tailscaled # tailscale.com/cmd/tailscaled ./required_version.go:11:2: undefined: you_need_Go_1_18_to_compile_Tailscale note: module requires Go 1.18 Change-Id: I39f5820de646703e19dde448dd86a7022252f75c Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
David Anderson	2a412ac9ee	.github/workflows: work around golang/go#51629 Incidentally, simplify the go generate CI workflow, by marking the dnsfallback update non-hermetic (so CI will skip it) rather than manually filter it out of `go list`. Updates #4194 Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Brad Fitzpatrick	18818763d1	derp: set Basic Constraints on metacert See https://github.com/golang/go/issues/51759#issuecomment-1071147836 Once we deploy this, tailscaled should work again for macOS users with Go 1.18.

Josh Bleecher Snyder	997b19545b	syncs: use TryLock and TryRLock instead of unsafe The docs say: Note that while correct uses of TryLock do exist, they are rare, and use of TryLock is often a sign of a deeper problem in a particular use of mutexes. Rare code! Or bad code! Who can tell! Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Maisem Ali	6b9d938c1a	types/views: add generic Slice[T] and remove StringSlice Also make IPPrefixSliceOf use Slice[netaddr.IPPrefix] as it also provides additional functions besides the standard ones provided by Slice[T]. Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
Denton Gentry	d8953bf2ba	cmd/derpprobe: don't alert for smaller failures. There is a Cosmic Background level of DERP Unreachability, with individual nodes or regions becoming unreachable briefly and returning a short time later. This is due to hosting provider outages or just the Internet sloshing about. Returning a 500 error pages a human. Being awoken at 3am for a transient error is annoying. For relatively small levels of badness don't page a human, just post to Slack. If the outage impacts a significant fraction of the DERP fleet, then page a human.

Josh Bleecher Snyder	26021b07ec	control/controlclient: only build certstore-related code with the Tailscale Go toolchain The certstore code is impacted by golang/go#51726. The Tailscale Go toolchain fork contains a temporary workaround, so it can compile it. Once the upstream toolchain can compile certstore, presumably in Go 1.18.1, we can revert this change. Note that depaware runs with the upstream toolchain. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	0ef74f37a5	net/dns/resolver: remove closure allocation explanation As of Go 1.18, the register ABI list includes arm64, amd64, ppc64, and ppc64le.

Josh Bleecher Snyder	f695f0b178	go.mod: update golang.org/x/tools and honnef.co/go/tools This is required for staticcheck to process code using Go 1.18. This puts us on a random commit on the bleeding edge of staticcheck, which isn't great, but there don't appear to have been any releases yet that support 1.18.
