Anton Tolchanov	fd6686d81a	tka: truncate long rotation signature chains When a rotation signature chain reaches a certain size, remove the oldest rotation signature from the chain before wrapping it in a new rotation signature. Since all previous rotation signatures are signed by the same wrapping pubkey (node's own tailnet lock key), the node can re-construct the chain, re-signing previous rotation signatures. This will satisfy the existing certificate validation logic. Updates #13185 Signed-off-by: Anton Tolchanov <anton@tailscale.com>	2 months ago
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.

Anton Tolchanov	4651827f20	tka: test SigCredential signatures and netmap filtering This change moves handling of wrapped auth keys to the `tka` package and adds a test covering auth key originating signatures (SigCredential) in netmap.

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.

Andrew Dunham	e9505e5432	ipn/ipnlocal: plumb health.Tracker into profileManager constructor Setting the field after-the-fact wasn't working because we could migrate prefs on creation, which would set health status for auto updates.

Brad Fitzpatrick	3672f29a4e	net/netns, net/dns/resolver, etc: make netmon required in most places The goal is to move more network state accessors to netmon.Monitor where they can be cheaper/cached. But first (this change and others) we need to make sure the one netmon.Monitor is plumbed everywhere. Some notable bits: * tsdial.NewDialer is added, taking a now-required netmon * because a tsdial.Dialer always has a netmon, anything taking both a Dialer and a NetMon is now redundant; take only the Dialer and get the NetMon from that if/when needed. * netmon.NewStatic is added, primarily for tests Updates tailscale/corp#10910 Updates tailscale/corp#18960 Updates #7967 Updates #3299 Change-Id: I877f9cb87618c4eb037cee098241d18da9c01691 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	6 months ago
Marwan Sulaiman	2dc0645368	ipn/ipnlocal,cmd/tailscale: persist tailnet name in user profile This PR starts to persist the NetMap tailnet name in SetPrefs so that tailscaled clients can use this value to disambiguate fast user switching from one tailnet to another that are under the same exact login. We will also try to backfill this information during backend starts and profile switches so that users don't have to re-authenticate their profile. The first client to use this new information is the CLI in 'tailscale switch -list' which now uses text/tabwriter to display the ID, Tailnet, and Account. Since account names are ambiguous, we allow the user to pass 'tailscale switch ID' to specify the exact tailnet they want to switch to.

Maisem Ali	d06a75dcd0	ipn/ipnlocal: fix deadlock in resetControlClientLocked resetControlClientLocked is called while b.mu was held and would call cc.Shutdown which would wait for the observer queue to drain. However, there may be active callbacks from cc already waiting for b.mu resulting in a deadlock. This makes it so that resetControlClientLocked does not call Shutdown, and instead just returns the value. It also makes it so that any status received from previous cc are ignored.

Brad Fitzpatrick	55bb7314f2	control/controlclient: replace a status func with Observer interface For now the method has only one interface (the same as the func it's replacing) but it will grow, eventually with the goal to remove the controlclient.Status type for most purposes.

Maisem Ali	235309adc4	all: store NL keys per profile This moves the NetworkLock key from a dedicated StateKey to be part of the persist.Persist struct. This struct is stored as part for ipn.Prefs and is also the place where we store the NodeKey. It also moves the ChonkDir from "/tka" to "/tka-profile/<profile-id>". The rename was intentional to be able to delete the "/tka" dir if it exists. This means that we will have a unique key per profile, and a unique directory per profile. Note: `tailscale logout` will delete the entire profile, including any keys. It currently does not delete the ChonkDir. Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago

Tom DNetto	a515fc517b	ipn/ipnlocal: make tkaSyncIfNeeded exclusive with a mutex Running corp/ipn#TestNetworkLockE2E has a 1/300 chance of failing, and deskchecking suggests thats whats happening are two netmaps are racing each other to be processed through tkaSyncIfNeededLocked. This happens in the first place because we release b.mu during network RPCs. To fix this, we make the tka sync logic an exclusive section, so two netmaps will need to wait for tka sync to complete serially (which is what we would want anyway, as the second run through probably wont need to sync).
