Nick Khyl	8bd442ba8c	util/winutil/gp, net/dns: add package for Group Policy API ... This adds a package with GP-related functions and types to be used in the future PRs. It also updates nrptRuleDatabase to use the new package instead of its own gpNotificationWatcher implementation. Updates #12687 Signed-off-by: Nick Khyl <nickk@tailscale.com>	5 months ago
Aaron Klotz	4d5d669cd5	net/dns: unconditionally write NRPT rules to local settings ... We were being too aggressive when deciding whether to write our NRPT rules to the local registry key or the group policy registry key. After once again reviewing the document which calls itself a spec (see issue), it is clear that the presence of the DnsPolicyConfig subkey is the important part, not the presence of values set in the DNSClient subkey. Furthermore, a footnote indicates that the presence of DnsPolicyConfig in the GPO key will always override its counterpart in the local key. The implication of this is important: we may unconditionally write our NRPT rules to the local key. We copy our rules to the policy key only when it contains NRPT rules belonging to somebody other than us.

Brad Fitzpatrick	dc7aa98b76	all: use set.Set consistently instead of map[T]struct{} ... I didn't clean up the more idiomatic map[T]bool with true values, at least yet. I just converted the relatively awkward struct{}-valued maps. Updates #cleanup Change-Id: I758abebd2bb1f64bc7a9d0f25c32298f4679c14f Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
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	1cae618b03	net/dns: add Windows group policy notifications to the NRPT rule manager ... As discussed in previous PRs, we can register for notifications when group policies are updated and act accordingly. This patch changes nrptRuleDatabase to receive notifications that group policy has changed and automatically move our NRPT rules between the local and group policy subkeys as needed.

Aaron Klotz	8cdfd12977	net/dns: update Windows split DNS settings to work alongside other NRPT entries set by group policy. ... When there are group policy entries for the NRPT that do not belong to Tailscale, we recognize that we need to add ourselves to group policy and use that registry key instead of the local one. We also refresh the group policy settings as necessary to ensure that our changes take effect immediately.
