Tom DNetto	4001d0bf25	assorted: plumb tka initialization & network-lock key into tailscaled ... - A network-lock key is generated if it doesn't already exist, and stored in the StateStore. The public component is communicated to control during registration. - If TKA state exists on the filesystem, a tailnet key authority is initialized (but nothing is done with it for now).

Tom DNetto	393a229de9	tka: implement synchronization mechanics ... This PR implements the synchronization mechanics for TKA: generating a SyncOffer, processing a SyncOffer to find an intersection, and computing the set of AUMs that should be transmitted to effect convergence. This is the final PR implementing core mechanics for TKA. Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago

Tom DNetto	ec4f849079	tka: implement filesystem-based tailchonk implementation ... FS implements Chonk, and given the expected load characteristics (frequent use of AUM() + ChildAUMs(), and infrequent use of Heads() + CommitVerifiedAUMs()), the implementation avoids scanning the filesystem to service AUM() and ChildAUMs().

Tom DNetto	cca25f6107	tka: implement Chonk type & an in-memory implementation ... Chonks are responsible for efficient storage of AUMs and other TKA state. For testing/prototyping I've implemented an in-memory version, but once we start to use this from tailscaled we'll need a file-based version. Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago

Tom DNetto	1cfd96cdc2	tka: implement AUM and Key types ... This is the first in a series of PRs implementing the internals for the Tailnet Key Authority. This PR implements the AUM and Key types, which are used by pretty much everything else. Future PRs: - The State type & related machinery - The Tailchonk (storage) type & implementation - The Authority type and sync implementation Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago
