Percy Wegmann	450bc9a6b8	cmd/derper,derp: make TCP write timeout configurable ... The timeout still defaults to 2 seconds, but can now be changed via command-line flag. Updates tailscale/corp#26045 Signed-off-by: Percy Wegmann <percy@tailscale.com>	11 months ago
Brad Fitzpatrick	150cd30b1d	ipn/ipnlocal: also use LetsEncrypt-baked-in roots for cert validation ... We previously baked in the LetsEncrypt x509 root CA for our tlsdial package. This moves that out into a new "bakedroots" package and is now also shared by ipn/ipnlocal's cert validation code (validCertPEM) that decides whether it's time to fetch a new cert. Otherwise, a machine without LetsEncrypt roots locally in its system roots is unable to use tailscale cert/serve and fetch certs.

Aaron Klotz	fcf90260ce	atomicfile: use ReplaceFile on Windows so that attributes and ACLs are preserved ... I moved the actual rename into separate, GOOS-specific files. On non-Windows, we do a simple os.Rename. On Windows, we first try ReplaceFile with a fallback to os.Rename if the target file does not exist. ReplaceFile is the recommended way to rename the file in this use case, as it preserves attributes and ACLs set on the target file.

Percy Wegmann	db05e83efc	cmd/derper: support explicit configuration of mesh dial hosts ... The --mesh-with flag now supports the specification of hostname tuples like derp1a.tailscale.com/derp1a-vpc.tailscale.com, which instructs derp to mesh with host 'derp1a.tailscale.com' but dial TCP connections to 'derp1a-vpc.tailscale.com'. For backwards compatibility, --mesh-with still supports individual hostnames. The logic which attempts to auto-discover '[host]-vpc.tailscale.com' dial hosts has been removed.

This adds a new generic result type (motivated by golang/go#70084) to try it out, and uses it in the new lineutil package (replacing the old lineread package), changing that package to return iterators: sometimes over []byte (when the input is all in memory), but sometimes iterators over results of []byte, if errors might happen at runtime.

Nick Khyl	e815ae0ec4	util/syspolicy, ipn/ipnlocal: update syspolicy package to utilize syspolicy/rsop ... In this PR, we update the syspolicy package to utilize syspolicy/rsop under the hood, and remove syspolicy.CachingHandler, syspolicy.windowsHandler and related code which is no longer used. We mark the syspolicy.Handler interface and RegisterHandler/SetHandlerForTest functions as deprecated, but keep them temporarily until they are no longer used in other repos. We also update the package to register setting definitions for all existing policy settings and to register the Registry-based, Windows-specific policy stores when running on Windows. Finally, we update existing internal and external tests to use the new API and add a few more tests and benchmarks. Updates #12687 Signed-off-by: Nick Khyl <nickk@tailscale.com>	1 year ago

Brad Fitzpatrick	64ac64fb66	net/tsaddr: use bart in NewContainsIPFunc, add tests, benchmarks ... NewContainsIPFunc was previously documented as performing poorly if there were many netip.Prefixes to search over. As such, we never it used it in such cases. This updates it to use bart at a certain threshold (over 6 prefixes, currently), at which point the bart lookup overhead pays off. This is currently kinda useless because we're not using it. But now we can and get wins elsewhere.

Brad Fitzpatrick	15fc6cd966	derp/derphttp: fix netcheck HTTPS probes ... The netcheck client, when no UDP is available, probes distance using HTTPS. Several problems: * It probes using /derp/latency-check. * But cmd/derper serves the handler at /derp/probe * Despite the difference, it work by accident until c8f4dfc8c0 which made netcheck's probe require a 2xx status code. * in tests, we only use derphttp.Handler, so the cmd/derper-installed mux routes aren't preesnt, so there's no probe. That breaks tests in airplane mode. netcheck.Client then reports "unexpected HTTP status 426" (Upgrade Required) This makes derp handle both /derp/probe and /derp/latency-check equivalently, and in both cmd/derper and derphttp.Handler standalone modes.

James Tucker	edbad6d274	cmd/derper: add user timeout and reduce TCP keepalive ... The derper sends an in-protocol keepalive every 60-65s, so frequent TCP keepalives are unnecessary. In this tuning TCP keepalives should never occur for a DERP client connection, as they will send an L7 keepalive often enough to always reset the TCP keepalive timer. If however a connection does not receive an ACK promptly it will now be shutdown, which happens sooner than it would with a normal TCP keepalive tuning. This re-tuning reduces the frequency of network traffic from derp to client, reducing battery cost.

Marwan Sulaiman	b819f66eb1	tsweb: propagate RequestID via context and entire request ... The recent addition of RequestID was only populated if the HTTP Request had returned an error. This meant that the underlying handler has no access to this request id and any logs it may have emitted were impossible to correlate to that request id. Therefore, this PR adds a middleware to generate request ids and pass them through the request context. The tsweb.StdHandler automatically populates this request id if the middleware is being used. Finally, inner handlers can use the context to retrieve that same request id and use it so that all logs and events can be correlated.

Brad Fitzpatrick	3d7fb6c21d	derp/derphttp: fix race in mesh watcher ... The derphttp client automatically reconnects upon failure. RunWatchConnectionLoop called derphttp.Client.WatchConnectionChanges once, but that wrapper method called the underlying derp.Client.WatchConnectionChanges exactly once on derphttp.Client's currently active connection. If there's a failure, we need to re-subscribe upon all reconnections. This removes the derphttp.Client.WatchConnectionChanges method, which was basically impossible to use correctly, and changes it to be a boolean field on derphttp.Client alongside MeshKey and IsProber. Then it moves the call to the underlying derp.Client.WatchConnectionChanges to derphttp's client connection code, so it's resubscribed on any reconnect. Some paranoia is then added to make sure people hold the API right, not calling derphttp.Client.RunWatchConnectionLoop on an already-started Client without having set the bool to true. (But still auto-setting it to true if that's the first method that's been called on that derphttp.Client, as is commonly the case, and prevents existing code from breaking) Fixes tailscale/corp#9916 Supercedes tailscale/tailscale#9719 Co-authored-by: Val <valerie@tailscale.com> Co-authored-by: Irbe Krumina <irbe@tailscale.com> Co-authored-by: Anton Tolchanov <anton@tailscale.com> Signed-off-by: Brad Fitzpatrick <brad@danga.com>	2 years ago
Aaron Klotz	95671b71a6	ipn, safesocket: use Windows token in LocalAPI ... On Windows, the idiomatic way to check access on a named pipe is for the server to impersonate the client on its current OS thread, perform access checks using the client's access token, and then revert the OS thread's access token back to its true self. The access token is a better representation of the client's rights than just a username/userid check, as it represents the client's effective rights at connection time, which might differ from their normal rights. This patch updates safesocket to do the aforementioned impersonation, extract the token handle, and then revert the impersonation. We retain the token handle for the remaining duration of the connection (the token continues to be valid even after we have reverted back to self). Since the token is a property of the connection, I changed ipnauth to wrap the concrete net.Conn to include the token. I then plumbed that change through ipnlocal, ipnserver, and localapi as necessary. I also added a PermitLocalAdmin flag to the localapi Handler which I intend to use for controlling access to a few new localapi endpoints intended for configuring auto-update.

Mihai Parparita	7330aa593e	all: avoid repeated default interface lookups ... On some platforms (notably macOS and iOS) we look up the default interface to bind outgoing connections to. This is both duplicated work and results in logspam when the default interface is not available (i.e. when a phone has no connectivity, we log an error and thus cause more things that we will try to upload and fail).

Anton Tolchanov	8546ff98fb	tsweb: move varz handler(s) into separate modules ... This splits Prometheus metric handlers exposed by tsweb into two modules: - `varz.Handler` exposes Prometheus metrics generated by our expvar converter; - `promvarz.Handler` combines our expvar-converted metrics and native Prometheus metrics. By default, tsweb will use the promvarz handler, however users can keep using only the expvar converter. Specifically, `tailscaled` now uses `varz.Handler` explicitly, which avoids a dependency on the (heavyweight) Prometheus client.
