2026-01-23all: remove AUTHORS file and references to itWill Norris2-2/+2
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>

2024-11-01net/socks5: optimize UDP relayVimT2-99/+119
Key changes: - No mutex for every udp package: replace syncs.Map with regular map for udpTargetConns - Use socksAddr as map key for better type safety - Add test for multi udp target Updates #7581 Change-Id: Ic3d384a9eab62dcbf267d7d6d268bf242cc8ed3c Signed-off-by: VimT <me@vimt.me>
2024-11-01net/socks5: fix UDP relay in userspace-networking modeVimT1-38/+63
This commit addresses an issue with the SOCKS5 UDP relay functionality when using the --tun=userspace-networking option. Previously, UDP packets were not being correctly routed into the Tailscale network in this mode. Key changes: - Replace single UDP connection with a map of connections per target - Use c.srv.dial for creating connections to ensure proper routing Updates #7581 Change-Id: Iaaa66f9de6a3713218014cf3f498003a7cac9832 Signed-off-by: VimT <me@vimt.me>

2023-01-27all: update copyright and license headersWill Norris2-6/+4
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>

2022-03-08net/socks5: always close client connections after servingMaisem Ali1-1/+1
Customer reported an issue where the connections were not closing, and would instead just stay open. This commit makes it so that we close out the connection regardless of what error we see. I've verified locally that it fixes the issue, we should add a test for this. Signed-off-by: Maisem Ali <maisem@tailscale.com>
2021-11-30net/tsdial: start of new package to unify all outbound dialing complexityBrad Fitzpatrick1-90/+0
For now this just deletes the net/socks5/tssocks implementation (and the DNSMap stuff from wgengine/netstack) and moves it into net/tsdial. Then initialize a Dialer early in tailscaled, currently only use for the outbound and SOCKS5 proxies. It will be plumbed more later. Notably, it needs to get down into the DNS forwarder for exit node DNS forwading in netstack mode. But it will also absorb all the peerapi setsockopt and netns Dial and tlsdial complexity too.
