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.

Andrew Dunham	45d2f4301f	proxymap, various: distinguish between different protocols Previously, we were registering TCP and UDP connections in the same map, which could result in erroneously removing a mapping if one of the two connections completes while the other one is still active. Add a "proto string" argument to these functions to avoid this. Additionally, take the "proto" argument in LocalAPI, and plumb that through from the CLI and add a new LocalClient method.

Adrian Dewhurst	0219317372	ipn/ipnlocal: improve sticky last suggestion The last suggested exit node needs to be incorporated in the decision making process when a new suggestion is requested, but currently it is not quite right: it'll be used if the suggestion code has an error or a netmap is unavailable, but it won't be used otherwise. Instead, this makes the last suggestion into a tiebreaker when making a random selection between equally-good options. If the last suggestion does not make it to the final selection pool, then a different suggestion will be made. Since LocalBackend.SuggestExitNode is back to being a thin shim that sets up the parameters to suggestExitNode, it no longer needs a test. Its test was unable to be comprehensive anyway as the code being tested contains an uncontrolled random number generator.

Adrian Dewhurst	cf9f507d47	ipn/ipnlocal: only build allowed suggested node list once Rather than building a new suggested exit node set every time, compute it once on first use. Currently, syspolicy ensures that values do not change without a restart anyway. Since the set is being constructed in a separate func now, the test code that manipulates syspolicy can live there, and the TestSuggestExitNode can now run in parallel with other tests because it does not have global dependencies.

Adrian Dewhurst	3bf2bddbb5	ipn/ipnlocal: improve testability of random node selection In order to test the sticky last suggestion code, a test was written for LocalBackend.SuggestExitNode but it contains a random number generator which makes writing comprehensive tests very difficult. This doesn't change how the last suggestion works, but it adds some infrastructure to make that easier in a later PR. This adds func parameters for the two randomized parts: breaking ties between DERP regions and breaking ties between nodes. This way tests can validate the entire list of tied options, rather than expecting a particular outcome given a particular random seed. As a result of this, the global random number generator can be used rather than seeding a local one each time. In order to see the tied nodes for the location based (i.e. Mullvad) case, pickWeighted needed to return a slice instead of a single arbitrary option, so there is a small change in how that works.
