Aaron Klotz	5f177090e3	util/winutil: ensure domain controller address is used when retrieving remote profile information We cannot directly pass a flat domain name into NetUserGetInfo; we must resolve the address of a domain controller first. This PR implements the appropriate resolution mechanisms to do that, and also exposes a couple of new utility APIs for future needs.

Aaron Klotz	7354547bd8	util/winutil: update UserProfile to ensure any environment variables in the roaming profile path are expanded Updates #12383 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	5 months ago
Aaron Klotz	bd2a6d5386	util/winutil: add UserProfile type for (un)loading user profiles S4U logons do not automatically load the associated user profile. In this PR we add UserProfile to handle that part. Windows docs indicate that we should try to resolve a remote profile path when present, so we attempt to do so when the local computer is joined to a domain.

Aaron Klotz	db39a43f06	util/winutil: add support for restarting Windows processes in specific sessions This PR is all about adding functionality that will enable the installer's upgrade sequence to terminate processes belonging to the previous version, and then subsequently restart instances belonging to the new version within the session(s) corresponding to the processes that were killed. There are multiple parts to this: * We add support for the Restart Manager APIs, which allow us to query the OS for a list of processes locking specific files; * We add the RestartableProcess and RestartableProcesses types that query additional information about the running processes that will allow us to correctly restart them in the future. These types also provide the ability to terminate the processes. * We add the StartProcessInSession family of APIs that permit us to create new processes within specific sessions. This is needed in order to properly attach a new GUI process to the same RDP session and desktop that its previously-terminated counterpart would have been running in. * I tweaked the winutil token APIs again. * A lot of this stuff is pretty hard to test without a very elaborate harness, but I added a unit test for the most complicated part (though it requires LocalSystem to run).

Aaron Klotz	ea693eacb6	util/winutil: add RegisterForRestart, allowing programs to indicate their preferences to the Windows restart manager In order for the installer to restart the GUI correctly post-upgrade, we need the GUI to be able to register its restart preferences. This PR adds API support for doing so. I'm adding it to OSS so that it is available should we need to do any such registrations on OSS binaries in the future.

Aaron Klotz	37925b3e7a	go.mod, cmd/tailscaled, ipn/localapi, util/osdiag, util/winutil, util/winutil/authenticode: add Windows module list to OS-specific logs that are written upon bugreport * We update wingoes to pick up new version information functionality (See pe/version.go in the https://github.com/dblohm7/wingoes repo); * We move the existing LogSupportInfo code (including necessary syscall stubs) out of util/winutil into a new package, util/osdiag, and implement the public LogSupportInfo function may be implemented for other platforms as needed; * We add a new reason argument to LogSupportInfo and wire that into localapi's bugreport implementation; * We add module information to the Windows implementation of LogSupportInfo when reason indicates a bugreport. We enumerate all loaded modules in our process, and for each one we gather debug, authenticode signature, and version information.

Aaron Klotz	2aa8299c37	cmd/tailscaled, util/winutil: log our registry keys during tailscaled startup In order to improve our ability to understand the state of policies and registry settings when troubleshooting, we enumerate all values in all subkeys. x/sys/windows does not already offer this, so we need to call RegEnumValue directly. For now we're just logging this during startup, however in a future PR I plan to also trigger this code during a bugreport. I also want to log more than just registry.

Aaron Klotz	44f13d32d7	cmd/tailscaled, util/winutil: log Windows service diagnostics when the wintun device fails to install I added new functions to winutil to obtain the state of a service and all its depedencies, serialize them to JSON, and write them to a Logf. When tstun.New returns a wrapped ERROR_DEVICE_NOT_AVAILABLE, we know that wintun installation failed. We then log the service graph rooted at "NetSetupSvc". We are interested in that specific service because network devices will not install if that service is not running.
