Kristoffer Dalby	506bd8c8eb	policy: more accurate node change ... This commit changes so that node changes to the policy is calculated if any of the nodes has changed in a way that might affect the policy. Previously we just checked if the number of nodes had changed, which meant that if a node was added and removed, we would be in a bad state.

Kristoffer Dalby	eb788cd007	make tags first class node owner (#2885) ... This PR changes tags to be something that exists on nodes in addition to users, to being its own thing. It is part of moving our tags support towards the correct tailscale compatible implementation. There are probably rough edges in this PR, but the intention is to get it in, and then start fixing bugs from 0.28.0 milestone (long standing tags issue) to discover what works and what doesnt.

Kristoffer Dalby	fddc7117e4	stability and race conditions in auth and node store (#2781) ... This PR addresses some consistency issues that was introduced or discovered with the nodestore. nodestore: Now returns the node that is being put or updated when it is finished. This closes a race condition where when we read it back, we do not necessarily get the node with the given change and it ensures we get all the other updates from that batch write. auth: Authentication paths have been unified and simplified. It removes a lot of bad branches and ensures we only do the minimal work. A comprehensive auth test set has been created so we do not have to run integration tests to validate auth and it has allowed us to generate test cases for all the branches we currently know of. integration: added a lot more tooling and checks to validate that nodes reach the expected state when they come up and down. Standardised between the different auth models. A lot of this is to support or detect issues in the changes to nodestore (races) and auth (inconsistencies after login and reaching correct state) This PR was assisted, particularly tests, by claude code.	2025-10-16 12:17:43 +02:00
Kristoffer Dalby	9d236571f4	state/nodestore: in memory representation of nodes ... Initial work on a nodestore which stores all of the nodes and their relations in memory with relationship for peers precalculated. It is a copy-on-write structure, replacing the "snapshot" when a change to the structure occurs. It is optimised for reads, and while batches are not fast, they are grouped together to do less of the expensive peer calculation if there are many changes rapidly. Writes will block until commited, while reads are never blocked. Signed-off-by: Kristoffer Dalby <kristoffer@tailscale.com>	2025-09-09 09:40:00 +02:00
