2026-01-23all: remove AUTHORS file and references to itWill Norris1-1/+1
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>

2023-08-24paths: remove wasm file, no-op stubs, make OS-specific funcs consistentBrad Fitzpatrick1-2/+19
Some OS-specific funcs were defined in init. Another used build tags and required all other OSes to stub it out. Another one could just be in the portable file. Simplify it a bit, removing a file and some stubs in the process. Updates #5794 Change-Id: I51df8772cc60a9335ac4c1dc0ab59b8a0d236961 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2023-01-27all: update copyright and license headersWill Norris1-3/+2
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>

2022-03-01cmd/tailscaled: default to userspace-networking mode on gokrazy, set pathsBrad Fitzpatrick1-1/+4
One of the current few steps to run Tailscale on gokrazy is to specify the --tun=userspace-networking flag: https://gokrazy.org/userguide/install/tailscale/ Instead, make it the default for now. Later we can change the default to kernel mode if available and fall back to userspace mode like Synology, once #391 is done. Likewise, set default paths for Gokrazy, as its filesystem hierarchy is not the Linux standard one. Instead, use the conventional paths as documented at https://gokrazy.org/userguide/install/tailscale/. Updates #1866 RELNOTE=default to userspace-networking mode on gokrazy Change-Id: I3766159a294738597b4b30629d2860312dbb7609 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2021-09-22ipn, paths: ensure that the state directory for Windows has the correct permsAaron Klotz1-0/+11
ProgramData has a permissive ACL. For us to safely store machine-wide state information, we must set a more restrictive ACL on our state directory. We set the ACL so that only talescaled's user (ie, LocalSystem) and the Administrators group may access our directory. We must include Administrators to ensure that logs continue to be easily accessible; omitting that group would force users to use special tools to log in interactively as LocalSystem, which is not ideal. (Note that the ACL we apply matches the ACL that was used for LocalSystem's AppData\Local). There are two cases where we need to reset perms: One is during migration from the old location to the new. The second case is for clean installations where we are creating the file store for the first time. Updates #2856 Signed-off-by: Aaron Klotz <aaron@tailscale.com>
2021-09-19ipn/ipnserver, paths, logpolicy: move Window config files out of %LocalAppData%Denton Gentry1-1/+1
C:\WINDOWS\system32\config\systemprofile\AppData\Local\ is frequently cleared for almost any reason: Windows updates, System Restore, even various System Cleaner utilities. The server-state.conf file in AppData\Local could be deleted at any time, which would break login until the node is removed from the Admin Panel allowing it to create a new key. Carefully copy any AppData state to ProgramData at startup. If copying the state fails, continue to use AppData so at least there will be connectivity. If there is no state, use ProgramData. We also migrate the log.conf file. Very old versions of Tailscale named the EXE tailscale-ipn, so the log conf was tailscale-ipn.log.conf and more recent versions preserved this filename and cmdName in logs. In this migration we always update the filename to c:\ProgramData\Tailscale\tailscaled.log.conf Updates https://github.com/tailscale/tailscale/issues/2856 Signed-off-by: Denton Gentry <dgentry@tailscale.com>
