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>	7 days ago
Andrew Lytvynov	d01081683c	go.mod: bump golang.org/x/crypto (#17907) ... Pick up a fix for https://pkg.go.dev/vuln/GO-2025-4116 (even though we're not affected). Updates #cleanup Change-Id: I9f2571b17c1f14db58ece8a5a34785805217d9dd Signed-off-by: Andrew Lytvynov <awly@tailscale.com>	2 months ago
Brad Fitzpatrick	c6af5bbfe8	all: add test for package comments, fix, add comments as needed ... Updates #cleanup Change-Id: Ic4304e909d2131a95a38b26911f49e7b1729aaef Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Joe Tsai	63b3c82587	ipn/local: log OS-specific diagnostic information as JSON (#11700) ... There is an undocumented 16KiB limit for text log messages. However, the limit for JSON messages is 256KiB. Even worse, logging JSON as text results in significant overhead since each double quote needs to be escaped. Instead, use logger.Logf.JSON to explicitly log the info as JSON. We also modify osdiag to return the information as structured data rather than implicitly have the package log on our behalf. This gives more control to the caller on how to log.

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.

Aaron Klotz	6b6a8cf843	util/osdiag: add query for Windows page file configuration and status ... It's very common for OOM crashes on Windows to be caused by lack of page file space (the NT kernel does not overcommit). Since Windows automatically manages page file space by default, unless the machine is out of disk space, this is typically caused by manual page file configurations that are too small. This patch obtains the current page file size, the amount of free page file space, and also determines whether the page file is automatically or manually managed.

Aaron Klotz	5fb1695bcb	util/osdiag, util/osdiag/internal/wsc: add code to probe the Windows Security Center for installed software ... The Windows Security Center is a component that manages the registration of security products on a Windows system. Only products that have obtained a special cert from Microsoft may register themselves using the WSC API. Practically speaking, most vendors do in fact sign up for the program as it enhances their legitimacy. From our perspective, this is useful because it gives us a high-signal source of information to query for the security products installed on the system. I've tied this query into the osdiag package and is run during bugreports. It uses COM bindings that were automatically generated by my prototype metadata processor, however that program still has a few bugs, so I had to make a few manual tweaks. I dropped those binding into an internal package because (for the moment, at least) they are effectively purpose-built for the osdiag use case. We also update the wingoes dependency to pick up BSTR.

Aaron Klotz	c17a817769	util/osdiag: add logging for winsock layered service providers to Windows bugreports ... The Layered Service Provider (LSP) is a deprecated (but still supported) mechanism for inserting user-mode DLLs into a filter chain between the Winsock API surface (ie, ws2_32.dll) and the internal user-mode interface to the networking stack. While their use is becoming more rare due to the aforementioned deprecation, it is still possible for third-party software to install their DLLs into this filter chain and interfere with Winsock API calls. Knowing whether this is happening is useful for troubleshooting. Fixes https://github.com/tailscale/tailscale/issues/8142 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	2 years ago
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.
