Brad Fitzpatrick	1bd14a072c	cmd/tailscale, ipn/localapi: move IP forwarding check to tailscaled, API ... Instead of having the CLI check whether IP forwarding is enabled, ask tailscaled. It has a better idea. If it's netstack, for instance, the sysctl values don't matter. And it's possible that only the daemon has permission to know.

Brad Fitzpatrick	a998fe7c3d	control/controlclient: support lazy machine key generation ... It's not done in the caller yet, but the controlclient does it now. Updates #1573 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	12ae2d73b3	control/controlclient: fix TS_DEBUG_MAP on requests ... The concrete type being encoded changed from a value to pointer earlier and this was never adjusted. (People don't frequently use TS_DEBUG_MAP to see requests, so it went unnoticed until now.) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Adrian Dewhurst	04dd6d1dae	control/controlclient: sign RegisterRequest (#1549) ... control/controlclient: sign RegisterRequest Some customers wish to verify eligibility for devices to join their tailnets using machine identity certificates. TLS client certs could potentially fulfill this role but the initial customer for this feature has technical requirements that prevent their use. Instead, the certificate is loaded from the Windows local machine certificate store and uses its RSA public key to sign the RegisterRequest message. There is room to improve the flexibility of this feature in future and it is currently only tested on Windows (although Darwin theoretically works too), but this offers a reasonable starting place for now.

Brad Fitzpatrick	0a02aaf813	control, ipn, tailcfg: remove golang.org/x/oauth2 dep, add tailcfg.Oauth2Token ... golang.org/x/oauth2 pulls in App Engine and grpc module dependencies, screwing up builds that depend on this module. Some background on the problem: https://go.googlesource.com/proposal/+/master/design/36460-lazy-module-loading.md Fixes tailscale/corp#1471 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	cc508be603	control/controlclient: remove redundant Hostinfo log ... The direct client already logs it in JSON form. Then it's immediately logged again in an unformatted dump, so this removes that unformatted one. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	6fbc9b3a98	control/controlclient: cache Windows version ... To atone for 1d7f9d5b4a, the revert of 4224b3f731. At least it's fast again, even if it's shelling out to cmd.exe (once now). Updates #1478 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	1d7f9d5b4a	Revert "control/controlclient: use API to get Windows version number" ... This reverts commit 4224b3f731. From https://github.com/tailscale/tailscale/pull/1494#discussion_r594852889 ... > Actually, I want all four numbers back.

Brad Fitzpatrick	f45a9e291b	tailcfg, control/controlclient: add MapResponse.PingRequest ... So the control server can test whether a client's actually present. Most clients are over HTTP/2, so these pings (to the same host) are super cheap. This mimics the earlier goroutine dump mechanism. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	ddfcc4326c	types/persist: split controlclient.Persist into a small leaf package ... This one alone doesn't modify the global dependency map much (depaware.txt if anything looks slightly worse), but it leave controlclient as only containing NetworkMap: bradfitz@tsdev:~/src/tailscale.com/ipn$ grep -F "controlclient." *.go backend.go: NetMap *controlclient.NetworkMap // new netmap received fake_test.go: b.notify(Notify{NetMap: &controlclient.NetworkMap{}}) fake_test.go: b.notify(Notify{NetMap: &controlclient.NetworkMap{}}) handle.go: netmapCache *controlclient.NetworkMap handle.go:func (h *Handle) NetMap() *controlclient.NetworkMap { Once that goes into a leaf package, then ipn doesn't depend on controlclient at all, and then the client gets smaller.

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	5efb0a8bca	cmd/tailscale: change formatting of "tailscale status" ... * show DNS name over hostname, removing domain's common MagicDNS suffix. only show hostname if there's no DNS name. but still show shared devices' MagicDNS FQDN. * remove nerdy low-level details by default: endpoints, DERP relay, public key. They're available in JSON mode still for those who need them. * only show endpoint or DERP relay when it's active with the goal of making debugging easier. (so it's easier for users to understand what's happening) The asterisks are gone. * remove Tx/Rx numbers by default for idle peers; only show them when there's traffic. * include peers' owner login names * add CLI option to not show peers (matching --self=true, --peers= also defaults to true) * sort by DNS/host name, not public key * reorder columns	4 years ago

Brad Fitzpatrick	2f04f49376	control/controlclient: use lite map request handler to avoid aborting streams ... Previously, any change to endpoints or hostinfo (or hostinfo's netinfo) would result in the long-running map request HTTP stream being torn down and restarted, losing all compression context along with it. This change makes us instead send a lite map request (OmitPeers: true, Stream: false) that doesn't subscribe to anything, and then the coordination server knows to not close other streams for that node when it recives a lite request.

Brad Fitzpatrick	e8ae355bb8	ipn: delete domainsForProxying, require explicit DNS search domains (mapver 9) (#1078) ... Previously the client had heuristics to calculate which DNS search domains to set, based on the peers' names. Unfortunately that prevented us from doing some things we wanted to do server-side related to node sharing. So, bump MapRequest.Version to 9 to signal that the client only uses the explicitly configured DNS search domains and doesn't augment it with its own list.

Josh Bleecher Snyder	56a7652dc9	wgkey: new package ... This is a replacement for the key-related parts of the wireguard-go wgcfg package. This is almost a straight copy/paste from the wgcfg package. I have slightly changed some of the exported functions and types to avoid stutter, added and tweaked some comments, and removed some now-unused code. To avoid having wireguard-go depend on this new package, wgcfg will keep its key types. We translate into and out of those types at the last minute. These few remaining uses will be eliminated alongside the rest of the wgcfg package. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
