Brad Fitzpatrick	6e967446e4	tsd: add package with System type to unify subsystem init, discovery This is part of an effort to clean up tailscaled initialization between tailscaled, tailscaled Windows service, tsnet, and the mac GUI.

Brad Fitzpatrick	1e876a3c1d	ipn/ipnlocal: fix fmt format arg type mismatch in log line It was printing like "v0xxxxxxxx" after version.Long became a func in `8b2ae47c31`. Fixes #7976 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
James Tucker	095d3edd33	ipn/ipnlocal: reenable profile tests on Windows This fix does not seem ideal, but the test infrastructure using a local goos doesn't seem to avoid all of the associated challenges, but is somewhat deeply tied to the setup. The core issue this addresses for now is that when run on Windows there can be no code paths that attempt to use an invalid UID string, which on Windows is described in [1]. For the goos="linux" tests, we now explicitly skip the affected migration code if runtime.GOOS=="windows", and for the Windows test we explicitly use the running users uid, rather than just the string "user1". We also now make the case where a profile exists and has already been migrated a non-error condition toward the outer API.

Marwan Sulaiman	ce11c82d51	ipn/store/awsstore: persist state with intelligent tiering Fixes #6784 This PR makes it so that we can persist the tailscaled state with intelligent tiering which increases the capacity from 4kb to 8kb Signed-off-by: Marwan Sulaiman <marwan@tailscale.com>	2 years ago
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). Fixed by passing around a netmon.Monitor to more places, so that we can use its cached interface state. Fixes #7850 Updates #7621 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	4722f7e322	all: move network monitoring from wgengine/monitor to net/netmon We're using it in more and more places, and it's not really specific to our use of Wireguard (and does more just link/interface monitoring). Also removes the separate interface we had for it in sockstats -- it's a small enough package (we already pull in all of its dependencies via other paths) that it's not worth the extra complexity.

Maisem Ali	c3ef6fb4ee	ipn/ipnlocal: handle masquerade addresses in PeerAPI Without this, the peer fails to do anything over the PeerAPI if it has a masquerade address. ``` Apr 19 13:58:15 hydrogen tailscaled[6696]: peerapi: invalid request from <ip>:58334: 100.64.0.1/32 not found in self addresses ``` Updates #8020 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Mihai Parparita	d0906cda97	net/sockstats: expose debug info Exposes some internal state of the sockstats package via the C2N and PeerAPI endpoints, so that it can be used for debugging. For now this includes the estimated radio on percentage and a second-by-second view of the times the radio was active. Also fixes another off-by-one error in the radio on percentage that was leading to >100% values (if n seconds have passed since we started to monitor, there may be n + 1 possible seconds where the radio could have been on).

Mihai Parparita	9a655a1d58	net/dnsfallback: more explicitly pass through logf function Redoes the approach from #5550 and #7539 to explicitly pass in the logf function, instead of having global state that can be overridden. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
James Tucker	8dec1a8724	.github/workflows: reenable Windows CI, disable broken tests We accidentally switched to ./tool/go in `4022796484` which resulted in no longer running Windows builds, as this is attempting to run a bash script. I was unable to quickly fix the various tests that have regressed, so instead I've added skips referencing #7876, which we need to back and fix.

Will Norris	5a3da3cd7f	ipn: add sockstat logger to stable builds This makes the sockstat logger available on all builds, but only enables it by default for unstable.

Aaron Klotz	90fd04cbde	ipn/ipnlocal, util/winutil/policy: modify Windows profile migration to load legacy prefs from within tailscaled I realized that a lot of the problems that we're seeing around migration and LocalBackend state can be avoided if we drive Windows pref migration entirely from within tailscaled. By doing it this way, tailscaled can automatically perform the migration as soon as the connection with the client frontend is established. Since tailscaled is already running as LocalSystem, it already has access to the user's local AppData directory. The profile manager already knows which user is connected, so we simply need to resolve the user's prefs file and read it from there. Of course, to properly migrate this information we need to also check system policies. I moved a bunch of policy resolution code out of the GUI and into a new package in util/winutil/policy.

Maisem Ali	e0d291ab8a	ipn/store: add support for stores to hook into a custom dialer For stores like k8s secrets we need to dial out to the k8s API as though Tailscale wasn't running. The issue currently only manifests when you try to use an exit node while running inside a k8s cluster and are trying to use Kubernetes secrets as the backing store. This doesn't address cmd/containerboot, which I'll do in a follow up. Updates #7695 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Andrew Dunham	c98652c333	doctor/permissions: add new check to print process permissions Since users can run tailscaled in a variety of ways (root, non-root, non-root with process capabilities on Linux), this check will print the current process permissions to the log to aid in debugging.

shayne	3177ccabe5	ipn/ipnlocal: [serve/funnel] use actual SrcAddr as X-Forwarded-For (#7600 ) The reverse proxy was sending the ingressd IPv6 down as the X-Forwarded-For.

shayne	7908b6d616	ipn/ipnlocal: [serve] Trim mountPoint prefix from proxy path (#7334 ) This change trims the mountPoint from the request URL path before sending the request to the reverse proxy. Today if you mount a proxy at `/foo` and request to `/foo/bar/baz`, we leak the `mountPoint` `/foo` as part of the request URL's path. This fix makes removed the `mountPoint` prefix from the path so proxied services receive requests as if they were running at the root (`/`) path. This could be an issue if the app generates URLs (in HTML or otherwise) and assumes `/path`. In this case, those URLs will 404. With that, I still think we should trim by default and not leak the `mountPoint` (specific to Tailscale) into whatever app is hosted. If it causes an issue with URL generation, I'd suggest looking at configuring an app-specific path prefix or running Caddy as a more advanced solution.

Will Norris	57a008a1e1	all: pass log IDs as the proper type rather than strings This change focuses on the backend log ID, which is the mostly commonly used in the client.

Mihai Parparita	731688e5cc	ipn/localapi: add endpoint for adding debug log entries Allows the iOS and macOS apps to include their frontend logs when generating bug reports (tailscale/corp#9982). Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	97b6d3e917	sockstats: remove per-interface stats from Get They're not needed for the sockstats logger, and they're somewhat expensive to return (since they involve the creation of a map per label). We now have a separate GetInterfaces() method that returns them instead (which we can still use in the PeerAPI debug endpoint). If changing sockstatlog to sample at 10,000 Hz (instead of the default of 10Hz), the CPU usage would go up to 59% on a iPhone XS. Removing the per-interface stats drops it to 20% (a no-op implementation of Get that returns a fixed value is 16%).

Mihai Parparita	b64d78d58f	sockstats: refactor validation to be opt-in Followup to #7499 to make validation a separate function ( GetWithValidation vs. Get). This way callers that don't need it don't pay the cost of a syscall per active TCP socket. Also clears the conn on close, so that we don't double-count the stats.

Maisem Ali	b797f773c7	ipn/ipnlocal: add support for funnel in tsnet Previously the part that handled Funnel connections was not aware of any listeners that tsnet.Servers might have had open so it would check against the ServeConfig and fail. Adding a ServeConfig for a TCP proxy was also not suitable in this scenario as that would mean creating two different listeners and have one forward to the other, which really meant that you could not have funnel and tailnet-only listeners on the same port. This also introduces the ipn.FunnelConn as a way for users to identify whether the call is coming over funnel or not. Currently it only holds the underlying conn and the target as presented in the "Tailscale-Ingress-Target" header. Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
