Alex Chan	b7658a4ad2	tstest/integration: add integration test for Tailnet Lock This patch adds an integration test for Tailnet Lock, checking that a node can't talk to peers in the tailnet until it becomes signed. This patch also introduces a new package `tstest/tkatest`, which has some helpers for constructing a mock control server that responds to TKA requests. This allows us to reduce boilerplate in the IPN tests. Updates tailscale/corp#33599 Signed-off-by: Alex Chan <alexc@tailscale.com>	1 week ago
Alex Chan	976bf24f5e	ipn/ipnlocal: remove the always-true CanSupportNetworkLock() Now that we support using an in-memory backend for TKA state (#17946), this function always returns `nil` – we can always support Network Lock. We don't need it any more. Plus, clean up a couple of errant TODOs from that PR.

Alex Chan	e1dd9222d4	ipn/ipnlocal, tka: compact TKA state after every sync Previously a TKA compaction would only run when a node starts, which means a long-running node could use unbounded storage as it accumulates ever-increasing amounts of TKA state. This patch changes TKA so it runs a compaction after every sync.

Alex Chan	1723cb83ed	ipn/ipnlocal: use an in-memory TKA store if FS is unavailable This requires making the internals of LocalBackend a bit more generic, and implementing the `tka.CompactableChonk` interface for `tka.Mem`.

Alex Chan	d47c697748	ipn/ipnlocal: skip TKA bootstrap request if Tailnet Lock is unavailable If you run tailscaled without passing a `--statedir`, Tailnet Lock is unavailable -- we don't have a folder to store the AUMs in. This causes a lot of unnecessary requests to bootstrap TKA, because every time the node receives a NetMap with some TKA state, it tries to bootstrap, fetches the bootstrap TKA state from the control plane, then fails with the error: TKA sync error: bootstrap: network-lock is not supported in this configuration, try setting --statedir We can't prevent the error, but we can skip the control plane request that immediately gets dropped on the floor. In local testing, a new node joining a tailnet caused three control plane requests which were unused. Updates tailscale/corp#19441 Signed-off-by: Alex Chan <alexc@tailscale.com>	1 month ago
Alex Chan	2b448f0696	ipn, tka: improve the logging around TKA sync and AUM errors * When we do the TKA sync, log whether TKA is enabled and whether we want it to be enabled. This would help us see if a node is making bootstrap errors. * When we fail to look up an AUM locally, log the ID of the AUM rather than a generic "file does not exist" error. These AUM IDs are cryptographic hashes of the TKA state, which itself just contains public keys and signatures. These IDs aren't sensitive and logging them is safe.

Nick Khyl	4e7f4086b2	ipn: generate LoginProfileView and use it instead of LoginProfile where appropriate Conventionally, we use views (e.g., ipn.PrefsView, tailcfg.NodeView, etc.) when dealing with structs that shouldn't be mutated. However, ipn.LoginProfile has been an exception so far, with a mix of passing and returning LoginProfile by reference (allowing accidental mutations) and by value (which is wasteful, given its current size of 192 bytes). In this PR, we generate an ipn.LoginProfileView and use it instead of passing/returning LoginProfiles by mutable reference or copying them when passing/returning by value. Now, LoginProfiles can only be mutated by (profileManager).setProfilePrefs. Updates #14823 Signed-off-by: Nick Khyl <nickk@tailscale.com>	10 months ago

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>	1 year ago

Anton Tolchanov	151b77f9d6	cmd/tl-longchain: tool to re-sign nodes with long rotation signatures In Tailnet Lock, there is an implicit limit on the number of rotation signatures that can be chained before the signature becomes too long. This program helps tailnet admins to identify nodes that have signatures with long chains and prints commands to re-sign those node keys with a fresh direct signature. It's a temporary mitigation measure, and we will remove this tool as we design and implement a long-term approach for rotation signatures. Example output: ``` 2024/08/20 18:25:03 Self: does not need re-signing 2024/08/20 18:25:03 Visible peers with valid signatures: 2024/08/20 18:25:03 Peer xxx2.yy.ts.net.

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	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.

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.

Tom DNetto	f1ab11e961	ipn/ipnlocal,tailcfg: introduce capability to gate TKA init paths Previously, `TAILSCALE_USE_WIP_CODE` was needed to hit a bunch of the TKA paths.

The end result is that it shouldn't be possible to initialize TKA (or subsequently use any of its features) without being sent the capability or setting the envknob on tailscaled yourself.
