Tom DNetto	be95aebabd	tka: implement credential signatures (key material delegation) ... This will be needed to support preauth-keys with network lock in the future, so getting the core mechanics out of the way now. Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago
Tom DNetto	79905a1162	tka: make storage a parameter rather than an Authority struct member ... Updates #5435 Based on the discussion in #5435, we can better support transactional data models by making the underlying storage layer a parameter (which can be specialized for the request) rather than a long-lived member of Authority. Now that Authority is just an instantaneous snapshot of state, we can do things like provide idempotent methods and make it cloneable, too. Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago
Tom DNetto	f580f4484f	tka: move disablement logic out-of-band from AUMs ... It doesn't make a ton of sense for disablement to be communicated as an AUM, because any failure in the AUM or chain mechanism will mean disablement wont function. Instead, tracking of the disablement secrets remains inside the state machine, but actual disablement and communication of the disablement secret is done by the caller.

Tom DNetto	f50043f6cb	tka,types/key: remove dependency for tailcfg & types/ packages on tka ... Following the pattern elsewhere, we create a new tka-specific types package for the types that need to couple between the serialized structure types, and tka.

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
