Brad Fitzpatrick	f1cddc6ecf	ipn{,/local},cmd/tailscale: add "sync" flag and pref to disable control map poll For manual (human) testing, this lets the user disable control plane map polls with "tailscale set --sync=false" (which survives restarts) and "tailscale set --sync" to restore. A high severity health warning is shown while this is active.

Alex Chan	139c395d7d	cmd/tailscale/cli: stabilise the output of `tailscale lock log --json` This patch changes the behaviour of `tailscale lock log --json` to make it more useful for users. It also introduces versioning of our JSON output. ## Changes to `tailscale lock log --json` Previously this command would print the hash and base64-encoded bytes of each AUM, and users would need their own CBOR decoder to interpret it in a useful way: ```json [ { "Hash": [ 80, 136, 151, … ], "Change": "checkpoint", "Raw": "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" } ] ``` Now we print the AUM in an expanded form that can be easily read by scripts, although we include the raw bytes for verification and auditing. ```json { "SchemaVersion": "1", "Messages": [ { "Hash": "KCEJPRKNSXJG2TPH3EHQRLJNLIIK2DV53FUNPADWA7BZJWBDRXZQ", "AUM": { "MessageKind": "checkpoint", "PrevAUMHash": null, "Key": null, "KeyID": null, "State": { … }, "Votes": null, "Meta": null, "Signatures": [ { "KeyID": "tlpub:e44874d1ea48ecf3d6dac8ca09cfe70dc958ad83b656393432016c3ed229c8d6", "Signature": "8yAKKHPpuOWsuTwfzgeAAPRXZIuCiavS5fjxeiCR2JTlYaU23NxNChezg7tVlEXdH+z151u9na/PQknxsSBwBQ==" } ] }, "Raw": "pAEFAvYFpQH2AopYIAkPN-8V3cJpkoC5ZY2-RI2Bcg2q5G7tRAQQd67W3YpnWCDPOo4KGeQBd8hdGsjoEQpSXyiPdlm-NXAlJ5dS1qEbFlggylNJDQM5ZQ2ULNsXxg2ZBFkPl_D93I1M56_rowU-UIlYIPZ_SxT9EA2Idy9kaCbsFzjX_s3Ms7584wWGbWd_f_QAWCBHYZzYiAPpQ-NXN-1Wn2fopQYk4yl7kNQcMXUKNAdt1lggcfjcuVACOH0J9pRNvYZQFOkbiBmLOW1hPKJsbC1D1GdYIKrJ38XMgpVMuTuBxM4YwoLmrK_RgXQw1uVEL3cywl3QWCA0FilVVv8uys8BNhS62cfNvCew1Pw5wIgSe3Prv8d8pFggQrwIt6ldYtyFPQcC5V18qrCnt7VpThACaz5RYzpx7RNYIKskOA7UoNiVtMkOrV2QoXv6EvDpbO26a01lVeh8UCeEA4KjAQECAQNYIORIdNHqSOzz1trIygnP5w3JWK2DtlY5NDIBbD7SKcjWowEBAgEDWCD27LpxiZNiA19k0QZhOWmJRvBdK2mz-dHu7rf0iGTPFwQb69Gt42fKNn0FGwRUiav_k6dDF4GiAVgg5Eh00epI7PPW2sjKCc_nDclYrYO2Vjk0MgFsPtIpyNYCWEDzIAooc-m45ay5PB_OB4AA9Fdki4KJq9Ll-PF6IJHYlOVhpTbc3E0KF7ODu1WURd0f7PXnW72dr89CSfGxIHAF" } ] } ``` This output was previously marked as unstable, and it wasn't very useful, so changing it should be fine. ## Versioning our JSON output This patch introduces a way to version our JSON output on the CLI, so we can make backwards-incompatible changes in future without breaking existing scripts or integrations. You can run this command in two ways: ``` tailscale lock log --json tailscale lock log --json=1 ``` Passing an explicit version number allows you to pick a specific JSON schema. If we ever want to change the schema, we increment the version number and users must opt-in to the new output. A bare `--json` flag will always return schema version 1, for compatibility with existing scripts.

Tom Proctor	d4c5b278b3	cmd/k8s-operator: support workload identity federation The feature is currently in private alpha, so requires a tailnet feature flag. Initially focuses on supporting the operator's own auth, because the operator is the only device we maintain that uses static long-lived credentials. All other operator-created devices use single-use auth keys. Testing steps: * Create a cluster with an API server accessible over public internet * kubectl get --raw /.well-known/openid-configuration \| jq '.issuer' * Create a federated OAuth client in the Tailscale admin console with: * The issuer from the previous step * Subject claim `system:serviceaccount:tailscale:operator` * Write scopes services, devices:core, auth_keys * Tag tag:k8s-operator * Allow the Tailscale control plane to get the public portion of the ServiceAccount token signing key without authentication: * kubectl create clusterrolebinding oidc-discovery \ --clusterrole=system:service-account-issuer-discovery \ --group=system:unauthenticated * helm install --set oauth.clientId=... --set oauth.audience=...

M. J. Fromberger	95426b79a9	logtail: avoid racing eventbus subscriptions with shutdown (#17695 ) In #17639 we moved the subscription into NewLogger to ensure we would not race subscribing with shutdown of the eventbus client. Doing so fixed that problem, but exposed another: As we were only servicing events occasionally when waiting for the network to come up, we could leave the eventbus to stall in cases where a number of network deltas arrived later and weren't processed. To address that, let's separate the concerns: As before, we'll Subscribe early to avoid conflicts with shutdown; but instead of using the subscriber directly to determine readiness, we'll keep track of the last-known network state in a selectable condition that the subscriber updates for us. When we want to wait, we'll wait on that condition (or until our context ends), ensuring all the events get processed in a timely manner.

Alex Chan	b7fe1cea9f	cmd/tailscale/cli: only print authURLs and device approval URLs once This patch fixes several issues related to printing login and device approval URLs, especially when `tailscale up` is interrupted: 1. Only print a login URL that will cause `tailscale up` to complete. Don't print expired URLs or URLs from previous login attempts. 2. Print the device approval URL if you run `tailscale up` after previously completing a login, but before approving the device. 3. Use the correct control URL for device approval if you run a bare `tailscale up` after previously completing a login, but before approving the device. 4. Don't print the device approval URL more than once (or at least, not consecutively). Updates tailscale/corp#31476 Updates #17361 ## How these fixes work This patch went through a lot of trial and error, and there may still be bugs! These notes capture the different scenarios and considerations as we wrote it, which are also captured by integration tests. 1. We were getting stale login URLs from the initial IPN state notification. When the IPN watcher was moved to before Start() in `c011369`, we mistakenly continued to request the initial state. This is only necessary if you start watching after you call Start(), because you may have missed some notifications. By getting the initial state before calling Start(), we'd get a stale login URL. If you clicked that URL, you could complete the login in the control server (if it wasn't expired), but your instance of `tailscale up` would hang, because it's listening for login updates from a different login URL. In this patch, we no longer request the initial state, and so we don't print a stale URL. 2. Once you skip the initial state from IPN, the following sequence: * Run `tailscale up` * Log into a tailnet with device approval * ^C after the device approval URL is printed, but without approving * Run `tailscale up` again means that nothing would ever be printed. `tailscale up` would send tailscaled the pref `WantRunning: true`, but that was already the case so nothing changes. You never get any IPN notifications, and in particular you never get a state change to `NeedsMachineAuth`. This means we'd never print the device approval URL. In this patch, we add a hard-coded rule that if you're doing a simple up (which won't trigger any other IPN notifications) and you start in the `NeedsMachineAuth` state, we print the device approval message without waiting for an IPN notification. 3. Consider the following sequence: * Run `tailscale up --login-server=<custom server>` * Log into a tailnet with device approval * ^C after the device approval URL is printed, but without approving * Run `tailscale up` again We'd print the device approval URL for the default control server, rather than the real control server, because we were using the `prefs` from the CLI arguments (which are all the defaults) rather than the `curPrefs` (which contain the custom login server). In this patch, we use the `prefs` if the user has specified any settings (and other code will ensure this is a complete set of settings) or `curPrefs` if it's a simple `tailscale up`. 4. Consider the following sequence: you've logged in, but not completed device approval, and you run `down` and `up` in quick succession. * `up`: sees state=NeedsMachineAuth * `up`: sends `{wantRunning: true}`, prints out the device approval URL * `down`: changes state to Stopped * `up`: changes state to Starting * tailscaled: changes state to NeedsMachineAuth * `up`: gets an IPN notification with the state change, and prints a second device approval URL Either URL works, but this is annoying for the user. In this patch, we track whether the last printed URL was the device approval URL, and if so, we skip printing it a second time. Signed-off-by: Alex Chan <alexc@tailscale.com>	2 months ago
