Brad Fitzpatrick	3d180c0376	go.mod, ssh/tailssh, tempfork/gliderlabs: bump x/crypto/ssh fork for NoClientAuthCallback Prep for evaluating SSHPolicy earlier to decide whether certs are required, which requires knowing the target SSH user.

Brad Fitzpatrick	e4d8d5e78b	net/packet, wgengine/netstack: remove workaround for old gvisor ECN bug Fixes #2642 Change-Id: Ic02251d24a4109679645d1c8336e0f961d0cce13 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	5a44f9f5b5	tempfork: temporarily fork gliderlabs/ssh and x/crypto/ssh While we rearrange/upstream things. gliderlabs/ssh is forked into tempfork from our prior fork at `be8b7add40` x/crypto/ssh OTOH is forked at https://github.com/tailscale/golang-x-crypto because it was gnarlier to vendor with various internal packages, etc. Its git history shows where it starts (2c7772ba30643b7a2026cbea938420dce7c6384d). Updates #3802 Change-Id: I546e5cdf831cfc030a6c42557c0ad2c58766c65f Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
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.

Maisem Ali	b2f269d5b7	net/dnsfallback: do not attempt lookups of IPs. Currently if the passed in host is an IP, Lookup still attempts to resolve it with a dns server. This makes it just return the IP directly. Updates tailscale/corp#4475 Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
Maisem Ali	b45bb577a0	net/dnscache: do not call LookupIPFallback if the context was canceled. When the context is canceled, dc.dialOne returns an error from line 345. This causes the defer on line 312 to try to resolve the host again, which triggers a dns lookup of "127.0.0.1" from derp.

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>	3 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.
