Maisem Ali	44937b59e7	tsnet: add Dial method to allow dialing out to the tailnet. ... Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
Brad Fitzpatrick	535b925d1b	derp/derphttp: add Client.Ping, SendPing methods ... Continuing work in 434af15a04, to make it possible for magicsock to probe whether a DERP server is still there. Updates #3619 Change-Id: I366a77c27e93b876734e64f445b85ef01eb590f2 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	434af15a04	derp: support client->server ping (and server->client pong) ... In prep for a future change to have client ping derp connections when their state is questionable, rather than aggressively tearing them down and doing a heavy reconnect when their state is unknown. We already support ping/pong in the other direction (servers probing clients) so we already had the two frame types, but I'd never finished this direction.

Brad Fitzpatrick	3dedcd1640	logpolicy, ipn/ipnserver: connect to logtail via tailscaled when needed ... This is for use by the Windows GUI client to log via when an exit node is in use, so the logs don't go out via the exit node and instead go directly, like tailscaled's. The dialer tried to do that in the unprivileged GUI by binding to a specific interface, but the "Internet Kill Switch" installed by tailscaled for exit nodes precludes that from working and instead the GUI fails to dial out. So, go through tailscaled (with a CONNECT request) instead.

Brad Fitzpatrick	5a9914a92f	wgengine/netstack: don't remove 255.255.255.255/32 from netstack ... The intent of the updateIPs code is to add & remove IP addresses to netstack based on what we get from the netmap. But netstack itself adds 255.255.255.255/32 apparently and we always fight it (and it adds it back?). So stop fighting it. Updates #2642 (maybe fixes? maybe.)

Joe Tsai	66164b9307	api: document API endpoint to manipulate keys (#3544) ... The new /keys endpoint allows you to list API and machine auth keys. You can also create machine auth key.

Brad Fitzpatrick	40e2b312b6	ipn/ipnserver, logpolicy: move Windows disk logging up earlier ... This moves the Windows-only initialization of the filelogger into logpolicy. Previously we only did it when babysitting the tailscaled subprocess, but this meant that log messages from the service itself never made it to disk. Examples that weren't logged to disk: * logtail unable to dial out, * DNS flush messages from the service * svc.ChangeRequest messages (#3581) This is basically the same fix as #3571 but staying in the Logf type, and avoiding build-tagged file (which wasn't quite a goal, but happened and seemed nice) Fixes #3570 Co-authored-by: Aaron Klotz <aaron@tailscale.com> Change-Id: Iacd80c4720b7218365ec80ae143339d030842702	3 years ago

Brad Fitzpatrick	8f43ddf1a2	ipn/ipnlocal, health: populate self node's Online bit in tailscale status ... One option was to just hide "offline" in the text output, but that doesn't fix the JSON output. The next option was to lie and say it's online in the JSON (which then fixes the "offline" in the text output). But instead, this sets the self node's "Online" to whether we're in an active map poll.

Josh Bleecher Snyder	681d4897cc	tstest/integration: remove t param in testNode methods ... testNodes have a reference to a testing.TB via their env. Use it instead of making the caller pass theirs.

Josh Bleecher Snyder	93ae11105d	ipn/ipnlocal: clear magicsock's netmap on logout ... magicsock was hanging onto its netmap on logout, which caused tailscale status to display partial information about a bunch of zombie peers.

Josh Bleecher Snyder	84a1106fa7	tstest/integration: make -verbose-tailscaled pass -verbose=2 to tailscaled ... If you're using -verbose-tailscaled, you're doing in-the-weeds debugging, so you probably want the verbose output. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Josh Bleecher Snyder	4691e012a9	tstest/integration: build binaries only once ... The existing code relied on the Go build cache to avoid needless work when obtaining the tailscale binaries. For non-obvious reasons, the binaries were getting re-linked every time, which added 600ms or so on my machine to every test. Instead, build the binaries exactly once, on demand. This reduces the time to run 'go test -count=5' from 34s to 10s on my machine. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Brad Fitzpatrick	adc97e9c4d	cmd/tailscale: make --accept-routes default true on Windows, macOS GUI ... One of the most annoying parts of using the Tailscale CLI on Windows and the macOS GUI is that Tailscale's GUIs default to running with "Route All" (accept all non-exitnode subnet routes) but the CLI--being originally for Linux--uses the Linux default, which is to not accept subnets. Which means if a Windows user does, e.g.: tailscale up --advertise-exit-node Or: tailscale up --shields-up ... then it'd warn about reverting the --accept-routes option, which the user never explicitly used. Instead, make the CLI's default match the platform/GUI's default. Change-Id: I15c804b3d9b0266e9ca8651e0c09da0f96c9ef8d Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Josh Bleecher Snyder	63cd581c3f	safesocket: add ConnectionStrategy, provide control over fallbacks ... fee2d9fad added support for cmd/tailscale to connect to IPNExtension. It came in two parts: If no socket was provided, dial IPNExtension first, and also, if dialing the socket failed, fall back to IPNExtension. The second half of that support caused the integration tests to fail when run on a machine that was also running IPNExtension. The integration tests want to wait until the tailscaled instances that they spun up are listening. They do that by dialing the new instance. But when that dial failed, it was falling back to IPNExtension, so it appeared (incorrectly) that tailscaled was running. Hilarity predictably ensued. If a user (or a test) explicitly provides a socket to dial, it is a reasonable assumption that they have a specific tailscaled in mind and don't want to fall back to IPNExtension. It is certainly true of the integration tests. Instead of adding a bool to Connect, split out the notion of a connection strategy. For now, the implementation remains the same, but with the details hidden a bit. Later, we can improve that. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Brad Fitzpatrick	39ffa16853	net/dnscache, net/tsdial: add DNS caching to tsdial UserDial ... This is enough to handle the DNS queries as generated by Go's net package (which our HTTP/SOCKS client uses), and the responses generated by the ExitDNS DoH server. This isn't yet suitable for putting on 100.100.100.100 where a number of different DNS clients would hit it, as this doesn't yet do EDNS0. It might work, but it's untested and likely incomplete. Likewise, this doesn't handle anything about truncation, as the exchanges are entirely in memory between Go or DoH. That would also need to be handled later, if/when it's hooked up to 100.100.100.100.
