Jordan Whited	1fc4268aea	cmd/stunstamp: increase probe jitter (#13362) ... We've added more probe targets recently which has resulted in more timeouts behind restrictive NATs in localized testing that don't like how many flows we are creating at once.

Nick Khyl	aeb15dea30	util/syspolicy/source: add package for reading policy settings from external stores ... We add package defining interfaces for policy stores, enabling creation of policy sources and reading settings from them. It includes a Windows-specific PlatformPolicyStore for GP and MDM policies stored in the Registry, and an in-memory TestStore for testing purposes. We also include an internal package that tracks and reports policy usage metrics when a policy setting is read from a store. Initially, it will be used only on Windows and Android, as macOS, iOS, and tvOS report their own metrics. However, we plan to use it across all platforms eventually.

Kubectl (or whoever is the client that initiates the 'kubectl exec' session recording) sends the terminal dimensions in a resize message that the API server proxy can intercept, however that races with the first server message that we need to record. This PR ensures we wait for the terminal dimensions to be processed from the first resize message before any other data is sent, so that for all sessions with terminal attached, the header of the session recording contains the terminal dimensions and the recording can be played by tsrecorder.

Nick Khyl	b48c8db69c	ipn/ipnlocal: set WantRunning upon an interactive login, but not during a seamless renewal or a profile switch ... The LocalBackend's state machine starts in NoState and soon transitions to NeedsLogin if there's no auto-start profile, with the profileManager starting with a new empty profile. Notably, entering the NeedsLogin state blocks engine updates. We expect the user to transition out of this state by logging in interactively, and we set WantRunning to true when controlclient enters the StateAuthenticated state. While our intention is correct, and completing an interactive login should set WantRunning to true, our assumption that logging into the current Tailscale profile is the only way to transition out of the NeedsLogin state is not accurate. Another common transition path includes an explicit profile switch (via LocalBackend.SwitchProfile) or an implicit switch when a Windows user connects to the backend. This results in a bug where WantRunning is set to true even when it was previously set to false, and the user expressed no intention of changing it. A similar issue occurs when switching from (sic) a Tailnet that has seamlessRenewalEnabled, regardless of the current state of the LocalBackend's state machine, and also results in unexpectedly set WantRunning. While this behavior is generally undesired, it is also incorrect that it depends on the control knobs of the Tailnet we're switching from rather than the Tailnet we're switching to. However, this issue needs to be addressed separately. This PR updates LocalBackend.SetControlClientStatus to only set WantRunning to true in response to an interactive login as indicated by a non-empty authURL.

Nick Khyl	80b2b45d60	ipn/ipnlocal: refactor and cleanup profileManager ... In preparation for multi-user and unattended mode improvements, we are refactoring and cleaning up `ipn/ipnlocal.profileManager`. The concept of the "current user", which is only relevant on Windows, is being deprecated and will soon be removed to allow more than one Windows user to connect and utilize `LocalBackend` according to that user's access rights to the device and specific Tailscale profiles. We plan to pass the user's identity down to the `profileManager`, where it can be used to determine the user's access rights to a given `LoginProfile`. While the new permission model in `ipnauth` requires more work and is currently blocked pending PR reviews, we are updating the `profileManager` to reduce its reliance on the concept of a single OS user being connected to the backend at the same time. We extract the switching to the default Tailscale profile, which may also trigger legacy profile migration, from `profileManager.SetCurrentUserID`. This introduces `profileManager.DefaultUserProfileID`, which returns the default profile ID for the current user, and `profileManager.SwitchToDefaultProfile`, which is essentially a shorthand for `pm.SwitchProfile(pm.DefaultUserProfileID())`. Both methods will eventually be updated to accept the user's identity and utilize that user's default profile. We make access checks more explicit by introducing the `profileManager.checkProfileAccess` method. The current implementation continues to use `profileManager.currentUserID` and `LoginProfile.LocalUserID` to determine whether access to a given profile should be granted. This will be updated to utilize the `ipnauth` package and the new permissions model once it's ready. We also expand access checks to be used more widely in the `profileManager`, not just when switching or listing profiles. This includes access checks in methods like `SetPrefs` and, most notably, `DeleteProfile` and `DeleteAllProfiles`, preventing unprivileged Windows users from deleting Tailscale profiles owned by other users on the same device, including profiles owned by local admins. We extract `profileManager.ProfilePrefs` and `profileManager.SetProfilePrefs` methods that can be used to get and set preferences of a given `LoginProfile` if `profileManager.checkProfileAccess` permits access to it. We also update `profileManager.setUnattendedModeAsConfigured` to always enable unattended mode on Windows if `Prefs.ForceDaemon` is true in the current `LoginProfile`, even if `profileManager.currentUserID` is `""`. This facilitates enabling unattended mode via `tailscale up --unattended` even if `tailscale-ipn.exe` is not running, such as when a Group Policy or MDM-deployed script runs at boot time, or when Tailscale is used on a Server Code or otherwise headless Windows environments.

Nothing in Tailscale depends on this (yet?), but it makes debugging in VMs behind natlab easier (e.g. you can ping all nodes), and other things might depend on this in the future. Mostly I'm trying to flesh out the IPv6 support in natlab now that we can write vnet tests.

Nick Khyl	961ee321e8	ipn/{ipnauth,ipnlocal,ipnserver,localapi}: start baby step toward moving access checks from the localapi.Handler to the LocalBackend ... Currently, we use PermitRead/PermitWrite/PermitCert permission flags to determine which operations are allowed for a LocalAPI client. These checks are performed when localapi.Handler handles a request. Additionally, certain operations (e.g., changing the serve config) requires the connected user to be a local admin. This approach is inherently racey and is subject to TOCTOU issues. We consider it to be more critical on Windows environments, which are inherently multi-user, and therefore we prevent more than one OS user from connecting and utilizing the LocalBackend at the same time. However, the same type of issues is also applicable to other platforms when switching between profiles that have different OperatorUser values in ipn.Prefs. We'd like to allow more than one Windows user to connect, but limit what they can see and do based on their access rights on the device (e.g., an local admin or not) and to the currently active LoginProfile (e.g., owner/operator or not), while preventing TOCTOU issues on Windows and other platforms. Therefore, we'd like to pass an actor from the LocalAPI to the LocalBackend to represent the user performing the operation. The LocalBackend, or the profileManager down the line, will then check the actor's access rights to perform a given operation on the device and against the current (and/or the target) profile. This PR does not change the current permission model in any way, but it introduces the concept of an actor and includes some preparatory work to pass it around. Temporarily, the ipnauth.Actor interface has methods like IsLocalSystem and IsLocalAdmin, which are only relevant to the current permission model. It also lacks methods that will actually be used in the new model. We'll be adding these gradually in the next PRs and removing the deprecated methods and the Permit* flags at the end of the transition.

Brad Fitzpatrick	0157000cab	tstest/natlab: fix IPv6 tests, remove TODOs ... The reason they weren't working was because the cmd/tta agent in the guest was dialing out to the test and the vnet couldn't map its global unicast IPv6 address to a node as it was just using a map[netip.Addr]*node and blindly trusting the *node was populated. Instead, it was nil, so the agent connection fetching didn't work for its RoundTripper and the test could never drive the node. That map worked for IPv4 but for IPv6 we need to use the method that takes into account the node's IPv6 SLAAC address. Most call sites had been converted but I'd missed that one. Also clean up some debug, and prohibit nodes' link-local unicast addresses from dialing 2000::/3 directly for now. We can allow that to be configured opt-in later (some sort of IPv6 NAT mode. Whatever it's called.) That mode was working on accident, but was confusing: Linux would do source address selection from link local for the first few seconds and then after SLAAC and DAD, switch to using the global unicast source address. Be consistent for now and force it to use the global unicast. Updates #13038 Change-Id: I85e973aaa38b43c14611943ff45c7c825ee9200a Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 months ago
