Will Norris	3ec5be3f51	all: remove AUTHORS file and references to it This file was never truly necessary and has never actually been used in the history of Tailscale's open source releases. A Brief History of AUTHORS files --- The AUTHORS file was a pattern developed at Google, originally for Chromium, then adopted by Go and a bunch of other projects. The problem was that Chromium originally had a copyright line only recognizing Google as the copyright holder. Because Google (and most open source projects) do not require copyright assignemnt for contributions, each contributor maintains their copyright. Some large corporate contributors then tried to add their own name to the copyright line in the LICENSE file or in file headers. This quickly becomes unwieldy, and puts a tremendous burden on anyone building on top of Chromium, since the license requires that they keep all copyright lines intact. The compromise was to create an AUTHORS file that would list all of the copyright holders. The LICENSE file and source file headers would then include that list by reference, listing the copyright holder as "The Chromium Authors". This also become cumbersome to simply keep the file up to date with a high rate of new contributors. Plus it's not always obvious who the copyright holder is. Sometimes it is the individual making the contribution, but many times it may be their employer. There is no way for the proejct maintainer to know. Eventually, Google changed their policy to no longer recommend trying to keep the AUTHORS file up to date proactively, and instead to only add to it when requested: https://opensource.google/docs/releasing/authors. They are also clear that: > Adding contributors to the AUTHORS file is entirely within the > project's discretion and has no implications for copyright ownership. It was primarily added to appease a small number of large contributors that insisted that they be recognized as copyright holders (which was entirely their right to do). But it's not truly necessary, and not even the most accurate way of identifying contributors and/or copyright holders. In practice, we've never added anyone to our AUTHORS file. It only lists Tailscale, so it's not really serving any purpose. It also causes confusion because Tailscalars put the "Tailscale Inc & AUTHORS" header in other open source repos which don't actually have an AUTHORS file, so it's ambiguous what that means. Instead, we just acknowledge that the contributors to Tailscale (whoever they are) are copyright holders for their individual contributions. We also have the benefit of using the DCO (developercertificate.org) which provides some additional certification of their right to make the contribution. The source file changes were purely mechanical with: git ls-files \| xargs sed -i -e 's/\(Tailscale Inc &\) AUTHORS/\1 contributors/g' Updates #cleanup Change-Id: Ia101a4a3005adb9118051b3416f5a64a4a45987d Signed-off-by: Will Norris <will@tailscale.com>	4 days ago
Andrea Gottardo	1d3e77f373	util/syspolicy: add ReadStringArray interface (#11857 ) Fixes tailscale/corp#19459 This PR adds the ability for users of the syspolicy handler to read string arrays from the MDM solution configured on the system.

Adrian Dewhurst	1ef5bd5381	util/osdiag, util/winutil: expose Windows policy key The Windows base registry key is already exported but the policy key was not. util/osdiag currently replicates the string rather than the preferred approach of reusing the constant.

Claire Wang	e3d6236606	winutil: refactor methods to get values from registry to also return (#9536 ) errors Updates tailscale/corp#14879 Signed-off-by: Claire Wang <claire@tailscale.com>	2 years ago
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.

Will Norris	71029cea2d	all: update copyright and license headers This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	3 years ago
Aaron Klotz	6e33d2da2b	ipn/ipnauth, util/winutil: add temporary LookupPseudoUser workaround to address os/user.LookupId errors on Windows I added util/winutil/LookupPseudoUser, which essentially consists of the bits that I am in the process of adding to Go's standard library. We check the provided SID for "S-1-5-x" where 17 <= x <= 20 (which are the known pseudo-users) and then manually populate a os/user.User struct with the correct information.

Aaron Klotz	3a74f2d2d7	cmd/tailscaled, util/winutil: add accessor functions for Windows system policies. This patch adds new functions to be used when accessing system policies, and revises callers to use the new functions. They first attempt the new registry path for policies, and if that fails, attempt to fall back to the legacy path. We keep non-policy variants of these functions because we should be able to retain the ability to read settings from locations that are not exposed to sysadmins for group policy edits. The remaining changes will be done in corp. Updates https://github.com/tailscale/tailscale/issues/3584 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	4 years ago
Aaron Klotz	d7962e3bcf	ipn/ipnserver, util/winutil: update workaround for os/user.LookupId failures on Windows to reject SIDs from deleted/invalid security principals. Our current workaround made the user check too lax, thus allowing deleted users. This patch adds a helper function to winutil that checks that the uid's SID represents a valid Windows security principal. Now if `lookupUserFromID` determines that the SID is invalid, we simply propagate the error.

David Crawshaw	6b9f8208f4	net/dns: do not run wsl.exe as LocalSystem It doesn't work. It needs to run as the user. https://github.com/microsoft/WSL/issues/4803 The mechanism for doing this was extracted from: https://web.archive.org/web/20101009012531/http://blogs.msdn.com/b/winsdk/archive/2009/07/14/launching-an-interactive-process-from-windows-service-in-windows-vista-and-later.aspx While here, we also reclaculate WSL distro set on SetDNS. This accounts for: 1. potential inability to access wsl.exe on startup 2. WSL being installed while Tailscale is running 3.
