Andrew Lytvynov	bc4c8b65c7	ipn/ipnlocal: periodically run auto-updates when "offline" (#12118 ) When the client is disconnected from control for any reason (typically just turned off), we should still attempt to update if auto-updates are enabled. This may help users who turn tailscale on infrequently for accessing resources. RELNOTE: Apply auto-updates even if the node is down or disconnected from the coordination server.

Maisem Ali	0b1a8586eb	cmd/natc: initial implementation of a NAT based connector This adds a new prototype `cmd/natc` which can be used to expose a services/domains to the tailnet. It requires the user to specify a set of IPv4 prefixes from the CGNAT range. It advertises these as normal subnet routes. It listens for DNS on the first IP of the first range provided to it. When it gets a DNS query it allocates an IP for that domain from the v4 range. Subsequent connections to the assigned IP are then tcp proxied to the domain. It is marked as a WIP prototype and requires the use of the `TAILSCALE_USE_WIP_CODE` env var. Updates tailscale/corp#20503 Signed-off-by: Maisem Ali <maisem@tailscale.com>	6 months ago

Adrian Dewhurst	3bf2bddbb5	ipn/ipnlocal: improve testability of random node selection In order to test the sticky last suggestion code, a test was written for LocalBackend.SuggestExitNode but it contains a random number generator which makes writing comprehensive tests very difficult. This doesn't change how the last suggestion works, but it adds some infrastructure to make that easier in a later PR. This adds func parameters for the two randomized parts: breaking ties between DERP regions and breaking ties between nodes. This way tests can validate the entire list of tied options, rather than expecting a particular outcome given a particular random seed. As a result of this, the global random number generator can be used rather than seeding a local one each time. In order to see the tied nodes for the location based (i.e. Mullvad) case, pickWeighted needed to return a slice instead of a single arbitrary option, so there is a small change in how that works.

Anton Tolchanov	01847e0123	ipn/ipnlocal: discard node keys that have been rotated out A non-signing node can be allowed to re-sign its new node keys following key renewal/rotation (e.g. via `tailscale up --force-reauth`). To be able to do this, node's TLK is written into WrappingPubkey field of the initial SigDirect signature, signed by a signing node. The intended use of this field implies that, for each WrappingPubkey, we typically expect to have at most one active node with a signature tracing back to that key. Multiple valid signatures referring to the same WrappingPubkey can occur if a client's state has been cloned, but it's something we explicitly discourage and don't support: https://tailscale.com/s/clone This change propagates rotation details (wrapping public key, a list of previous node keys that have been rotated out) to netmap processing, and adds tracking of obsolete node keys that, when found, will get filtered out.

Maisem Ali	42cfbf427c	tsnet,wgengine/netstack: add ListenPacket and tests This adds a new ListenPacket function on tsnet.Server which acts mostly like `net.ListenPacket`. Unlike `Server.Listen`, this requires listening on a specific IP and does not automatically listen on both V4 and V6 addresses of the Server when the IP is unspecified. To test this, it also adds UDP support to tsdial.Dialer.UserDial and plumbs it through the localapi. Then an associated test to make sure the UDP functionality works from both sides.

Andrea Gottardo	dd77111462	xcode/iOS: set MatchDomains when no route requires a custom DNS resolver (#10576 ) Updates https://github.com/tailscale/corp/issues/15802. On iOS exclusively, this PR adds logic to use a split DNS configuration in more cases, with the goal of improving battery life. Acting as the global DNS resolver on iOS should be avoided, as it leads to frequent wakes of IPNExtension. We try to determine if we can have Tailscale only handle DNS queries for resources inside the tailnet, that is, all routes in the DNS configuration do not require a custom resolver (this is the case for app connectors, for instance). If so, we set all Routes as MatchDomains. This enables a split DNS configuration which will help preserve battery life. Effectively, for the average Tailscale user who only relies on MagicDNS to resolve *.ts.net domains, this means that Tailscale DNS will only be used for those domains. This PR doesn't affect users with Override Local DNS enabled. For these users, there should be no difference and Tailscale will continue acting as a global DNS resolver.

James Tucker	8d1249550a	net/netcheck,wgengine/magicsock: add potential workaround for Palo Alto DIPP misbehavior Palo Alto firewalls have a typically hard NAT, but also have a mode called Persistent DIPP that is supposed to provide consistent port mapping suitable for STUN resolution of public ports. Persistent DIPP works initially on most Palo Alto firewalls, but some models/software versions have a bug which this works around. The bug symptom presents as follows: - STUN sessions resolve a consistent public IP:port to start with - Much later netchecks report the same IP:Port for a subset of sessions, most often the users active DERP, and/or the port related to sustained traffic. - The broader set of DERPs in a full netcheck will now consistently observe a new IP:Port. - After this point of observation, new inbound connections will only succeed to the new IP:Port observed, and existing/old sessions will only work to the old binding. In this patch we now advertise the lowest latency global endpoint discovered as we always have, but in addition any global endpoints that are observed more than once in a single netcheck report. This should provide viable endpoints for potential connection establishment across a NAT with this behavior.
