Maisem Ali	c434e47f2d	ssh/tailssh: always use current time for policy evaluation Whenever the SSH policy changes we revaluate all open connections to make sure they still have access. This check was using the wrong timestamp and would match against expired policies, however this really isn't a problem today as we don't have policy that would be impacted by this check. Fixing it for future use. Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago

Aaron Klotz	4baf34cf25	net/dns: set appropriate Windows registry values to prevent it from sending DNS changes concerning our interface to AD domain controllers. We do this unconditionally inside SetDNS such that the values are always set before we make any other changes to DNS configurations. It should not be harmful for the settings to remain even when other DNS settings are cleared out (since they only affect our network interface). See https://docs.microsoft.com/en-us/troubleshoot/windows-server/networking/configure-dns-dynamic-updates-windows-server-2003 for details about the registry value.

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.

James Tucker	76256d22d8	wgengine/router: windows: set SkipAsSource on IPv6 LL addresses Link-local addresses on the Tailscale interface are not routable. Ideally they would be removed, however, a concern exists that the operating system will attempt to re-add them which would lead to thrashing. Setting SkipAsSource attempts to avoid production of packets using the address as a source in any default behaviors. Before, in powershell: `ping (hostname)` would ping the link-local address of the Tailscale interface, and fail. After: `ping (hostname)` now pings the link-local address on the next highest priority metric local interface. Fixes #4647 Signed-off-by: James Tucker <james@tailscale.com>	2 years ago

Xe Iaso	dee95d0894	cmd/gitops-pusher: add new GitOps assistant (#4893 ) This is for an upcoming blogpost on how to manage Tailscale ACLs using a GitOps flow. This tool is intended to be used in CI and will allow users to have a git repository be the ultimate source of truth for their ACL file. This enables ACL changes to be proposed, approved and discussed before they are applied. Signed-off-by: Xe <xe@tailscale.com>	2 years ago

Joe Tsai	96f73b3894	logtail: do not panic in PrivateID.PublicID (#4815 ) It is not idiomatic for Go code to panic for situations that can be normal. For example, if a server receives PrivateID from a client, it is normal for the server to call PrivateID.PublicID to validate that the PublicID matches. However, doing so would panic prior to this change. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	3 years ago
