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>	2 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>	3 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. A new WSL distrobution being installed Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
