Denton Gentry	b46c5ae82a	cmd/sniproxy: draw the rest of the DNS owl. Add a DNS server which always responds as its own IP addresses. Additionally add a tsnet TailscaleIPs() function to return the IP addresses, both IPv4 and IPv6.

Brad Fitzpatrick	0f4359116e	tsnet: add UDP support to Server.Listen No ListenPacket support yet, but Listen with a udp network type fit easier into netstack's model to start. Then added an example of using it to cmd/sniproxy with a little udp :53 handler. No tests in tsnet yet because we don't have support for dialing over UDP in tsnet yet. When that's done, a new test can test both sides. Updates #5871 Updates #1748 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Mihai Parparita	9cb332f0e2	sockstats: instrument networking code paths Uses the hooks added by tailscale/go#45 to instrument the reads and writes on the major code paths that do network I/O in the client. The convention is to use "<package>.<type>:<label>" as the annotation for the responsible code path. Enabled on iOS, macOS and Android only, since mobile platforms are the ones we're most interested in, and we are less sensitive to any throughput degradation due to the per-I/O callback overhead (macOS is also enabled for ease of testing during development). For now just exposed as counters on a /v0/sockstats PeerAPI endpoint. We also keep track of the current interface so that we can break out the stats by interface.

Mihai Parparita	fa932fefe7	net/interfaces: redo how we get the default interface on macOS and iOS With #6566 we added an external mechanism for getting the default interface, and used it on macOS and iOS (see tailscale/corp#8201). The goal was to be able to get the default physical interface even when using an exit node (in which case the routing table would say that the Tailscale utun* interface is the default). However, the external mechanism turns out to be unreliable in some cases, e.g. when multiple cellular interfaces are present/toggled (I have occasionally gotten my phone into a state where it reports the pdp_ip1 interface as the default, even though it can't actually route traffic). It was observed that `ifconfig -v` on macOS reports an "effective interface" for the Tailscale utn* interface, which seems promising. By examining the ifconfig source code, it turns out that this is done via a SIOCGIFDELEGATE ioctl syscall. Though this is a private API, it appears to have been around for a long time (e.g. it's in the 10.13 xnu release at https://opensource.apple.com/source/xnu/xnu-4570.41.2/bsd/net/if_types.h.auto.html) and thus is unlikely to go away. We can thus use this ioctl if the routing table says that a utun* interface is the default, and go back to the simpler mechanism that we had before #6566.

Andrew Dunham	2755f3843c	health, net/tlsdial: add healthcheck for self-signed cert When we make a connection to a server, we previously would verify with the system roots, and then fall back to verifying with our baked-in Let's Encrypt root if the system root cert verification failed. We now explicitly check for, and log a health error on, self-signed certificates. Additionally, we now always verify against our baked-in Let's Encrypt root certificate and log an error if that isn't successful. We don't consider this a health failure, since if we ever change our server certificate issuer in the future older non-updated versions of Tailscale will no longer be healthy despite being able to connect.

Anton Tolchanov	100d8e909e	cmd/derpprobe: migrate to the prober framework `prober.DERP` was created in #5988 based on derpprobe. Having used it instead of derpprobe for a few months, I think we have enough confidence that it works and can now migrate derpprobe to use the prober framework and get rid of code duplication. A few notable changes in behaviour: - results of STUN probes over IPv4 and IPv6 are now reported separately; - TLS probing now includes OCSP verification; - probe names in the output have changed; - ability to send Slack notification from the prober has been removed. Instead, the prober now exports metrics in Expvar (/debug/vars) and Prometheus (/debug/varz) formats.

As such, we remove it. We also normalize the limit for max in-flight DNS queries on iOS (it was 64, now its 256 as per other platforms). It was 64 for the sake of being cautious about memory, but now we have 50Mb (iOS-15 and greater) instead of 15Mb so we have the spare headroom.

Incidentally also fix a very minor bug where headless services would get completely ignored, rather than reconciled into the correct state.

Joe Tsai	2e5d08ec4f	net/connstats: invert network logging data flow (#6272 ) Previously, tstun.Wrapper and magicsock.Conn managed their own statistics data structure and relied on an external call to Extract to extract (and reset) the statistics. This makes it difficult to ensure a maximum size on the statistics as the caller has no introspection into whether the number of unique connections is getting too large. Invert the control flow such that a connstats.Statistics is registered with tstun.Wrapper and magicsock.Conn. Methods on non-nil connstats.Statistics are called for every packet. This allows the implementation of connstats.Statistics (in the future) to better control when it needs to flush to ensure bounds on maximum sizes. The value registered into tstun.Wrapper and magicsock.Conn could be an interface, but that has two performance detriments: 1. Method calls on interface values are more expensive since they must go through a virtual method dispatch. 2. The implementation would need a sync.Mutex to protect the statistics value instead of using an atomic.Pointer. Given that methods on constats.Statistics are called for every packet, we want reduce the CPU cost on this hot path. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	3 years ago

Also, it uses the new async LocalBackend support in ipnserver.Server so the Server can start serving HTTP immediately, even if tun takes awhile to come up.

Brad Fitzpatrick	ea25ef8236	util/set: add new set package for SetHandle type We use this pattern in a number of places (in this repo and elsewhere) and I was about to add a fourth to this repo which was crossing the line.

Brad Fitzpatrick	e8cc78b1af	ipn/ipnserver: change Server to let LocalBackend be supplied async This is step 1 of de-special-casing of Windows and letting the LocalAPI HTTP server start serving immediately, even while the rest of the world (notably the Engine and its TUN device) are being created, which can take a few to dozens of seconds on Windows. With this change, the ipnserver.New function changes to not take an Engine and to return immediately, not returning an error, and let its Run run immediately. If its ServeHTTP is called when it doesn't yet have a LocalBackend, it returns an error. A TODO in there shows where a future handler will serve status before an engine is available. Future changes will: * delete a bunch of tailscaled_windows.go code and use this new API * add the ipnserver.Server ServerHTTP handler to await the engine being available * use that handler in the Windows GUI client Updates #6522 Change-Id: Iae94e68c235e850b112a72ea24ad0e0959b568ee Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Aaron Klotz	033bd94d4c	cmd/tailscaled, wgengine/router: use wingoes/com for COM initialization instead of go-ole This patch removes the crappy, half-backed COM initialization used by `go-ole` and replaces that with the `StartRuntime` function from `wingoes`, a library I have started which, among other things, initializes COM properly. In particular, we should always be initializing COM to use the multithreaded apartment. Every single OS thread in the process becomes implicitly initialized as part of the MTA, so we do not need to concern ourselves as to whether or not any particular OS thread has initialized COM. Furthermore, we no longer need to lock the OS thread when calling methods on COM interfaces. Single-threaded apartments are designed solely for working with Win32 threads that have a message pump; any other use of the STA is invalid.

Joe Tsai	b2035a1dca	cmd/netlogfmt: handle any stream of network logs (#6108 ) Make netlogfmt useful regardless of the exact schema of the input. If a JSON object looks like a network log message, then unmarshal it as one and then print it. This allows netlogfmt to support both a stream of JSON objects directly serialized from netlogtype.Message, or the schema returned by the /api/v2/tailnet/{{tailnet}}/network-logs API endpoint.

Mihai Parparita	d60f7fe33f	cmd/tsconnect: run wasm-opt on the generated wasm file Saves about 1.4MB from the generated wasm file. The Brotli size is basically unchanged (it's actually slightly larger, by 40K), suggesting that most of the size delta is due to not inlining and other changes that were easily compressible. However, it still seems worthwhile to have a smaller final binary, to reduce parse time and increase likelihood that we fit in the browser's disk cache. Actual performance appears to be unchanged.

Brad Fitzpatrick	45a3de14a6	cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support As noted in #5617, our documented method of blocking log.tailscale.io DNS no longer works due to bootstrap DNS. Instead, provide an explicit flag (--no-logs-no-support) and/or env variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher uploads. It also sets a bit on Hostinfo to say that the node is in that mode so we can end any support tickets from such nodes more quickly. This does not yet provide an easy mechanism for users on some platforms (such as Windows, macOS, Synology) to set flags/env. On Linux you'd used /etc/default/tailscaled typically.
