Nick Khyl	c32efd9118	various: create a catch-all NRPT rule when "Override local DNS" is enabled on Windows Without this rule, Windows 8.1 and newer devices issue parallel DNS requests to DNS servers associated with all network adapters, even when "Override local DNS" is enabled and/or a Mullvad exit node is being used, resulting in DNS leaks. This also adds "disable-local-dns-override-via-nrpt" nodeAttr that can be used to disable the new behavior if needed.

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
Eng Zer Jun	f0347e841f	refactor: move from io/ioutil to io and os packages The io/ioutil package has been deprecated as of Go 1.16 [1]. This commit replaces the existing io/ioutil functions with their new definitions in io and os packages.

David Anderson	a320d70614	net/dns: fall back to copy+delete/truncate if moving to/from /etc/resolv.conf fails. In some containers, /etc/resolv.conf is a bind-mount from outside the container. This prevents renaming to or from /etc/resolv.conf, because it's on a different filesystem from linux's perspective. It also prevents removing /etc/resolv.conf, because doing so would break the bind-mount. If we find ourselves within this environment, fall back to using copy+delete when renaming to /etc/resolv.conf, and copy+truncate when renaming from /etc/resolv.conf.

David Crawshaw	9b063b86c3	net/dns: factor directManager out over an FS interface This is preliminary work for using the directManager as part of a wslManager on windows, where in addition to configuring windows we'll use wsl.exe to edit the linux file system and modify the system resolv.conf. The pinholeFS is a little funky, but it's designed to work through simple unix tools via wsl.exe without invoking bash. I would not have thought it would stand on its own like this, but it turns out it's useful for writing a test for the directManager. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
