Brad Fitzpatrick	5df12b9059	client/tailscale, cmd/tailscale, localapi: add 'tailscale nc' (actually) Adds missing file from `fc12cbfcd3`. GitHub was having issues earlier and it was all green because the checks never actually ran, but the DCO non-Actions check at least did, so "green" and I merged, not realizing it hadn't really run anything. Updates #3802 Change-Id: I29f605eebe5336f1f3ca28ebb78b092dd99d9fd8 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	fc12cbfcd3	client/tailscale, cmd/tailscale, localapi: add 'tailscale nc' This adds a "tailscale nc" command that acts a bit like "nc", but dials out via tailscaled via localapi. This is a step towards a "tailscale ssh", as we'll use "tailscale nc" as a ProxyCommand for in some cases (notably in userspace mode). But this is also just useful for debugging & scripting.

Dave Anderson	0968b2d55a	prober: support adding key/value labels to probes. (#4250 ) prober: add labels to Probe instances.

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.

David Anderson	7b4960316b	tsweb: add PrometheusVar, for vars that want to output varz themselves.

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.

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>	2 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.
