Anton Tolchanov	781f79408d	ipn/ipnlocal: allow multiple signature chains from the same SigCredential Detection of duplicate Network Lock signature chains added in `01847e0123` failed to account for chains originating with a SigCredential signature, which is used for wrapped auth keys. This results in erroneous removal of signatures that originate from the same re-usable auth key. This change ensures that multiple nodes created by the same re-usable auth key are not getting filtered out by the network lock.

Aaron Klotz	da078b4c09	util/winutil: add package for logging into Windows via Service-for-User (S4U) This PR ties together pseudoconsoles, user profiles, s4u logons, and process creation into what is (hopefully) a simple API for various Tailscale services to obtain Windows access tokens without requiring knowledge of any Windows passwords. It works both for domain-joined machines (Kerberos) and non-domain-joined machines. The former case is fairly straightforward as it is fully documented. OTOH, the latter case is not documented, though it is fully defined in the C headers in the Windows SDK. The documentation blanks were filled in by reading the source code of Microsoft's Win32 port of OpenSSH. We need to do a bit of acrobatics to make conpty work correctly while creating a child process with an s4u token; see the doc comments above startProcessInternal for details.

Andrew Dunham	53a5d00fff	net/dns: ensure /etc/resolv.conf is world-readable even with a umask Previously, if we had a umask set (e.g. 0027) that prevented creating a world-readable file, /etc/resolv.conf would be created without the o+r bit and thus other users may be unable to resolve DNS. Since a umask only applies to file creation, chmod the file after creation and before renaming it to ensure that it has the appropriate permissions.

Jonathan Nobels	27033c6277	net/dns: recheck DNS config on SERVFAIL errors (#12547 ) Fixes tailscale/corp#20677 Replaces the original attempt to rectify this (by injecting a netMon event) which was both heavy handed, and missed cases where the netMon event was "minor". On apple platforms, the fetching the interface's nameservers can and does return an empty list in certain situations. Apple's API in particular is very limiting here. The header hints at notifications for dns changes which would let us react ahead of time, but it's all private APIs. To avoid remaining in the state where we end up with no nameservers but we absolutely need them, we'll react to a lack of upstream nameservers by attempting to re-query the OS. We'll rate limit this to space out the attempts. It seems relatively harmless to attempt a reconfig every 5 seconds (triggered by an incoming query) if the network is in this broken state. Missing nameservers might possibly be a persistent condition (vs a transient error), but that would also imply that something out of our control is badly misconfigured. Tested by randomly returning [] for the nameservers. When switching between Wifi networks, or cell->wifi, this will randomly trigger the bug, and we appear to reliably heal the DNS state.

Fran Bull	7eb8a77ac8	appc: don't schedule advertisement of 0 routes When the store-appc-routes flag is on for a tailnet we are writing the routes more often than seems necessary.
