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
Maisem Ali	fe81ee62d7	ipn/ipnlocal: do controlclient.Shutdown in a different goroutine ... We do not need to wait for it to complete.

Brad Fitzpatrick	3f8e185003	health: add Warnable, move ownership of warnable items to callers ... The health package was turning into a rando dumping ground. Make a new Warnable type instead that callers can request an instance of, and then Set it locally in their code without the health package being aware of all the things that are warnable. (For plenty of things the health package will want to know details of how Tailscale works so it can better prioritize/suppress errors, but lots of the warnings are pretty leaf-y and unrelated) This just moves two of the health warnings. Can probably move more later. Change-Id: I51e50e46eb633f4e96ced503d3b18a1891de1452 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

Aaron Klotz	73b8968404	ipn/ipnlocal: ensure Persist information is saved to server mode start state ... Numerous issues have been filed concerning an inability to install and run Tailscale headlessly in unattended mode, particularly after rebooting. The server mode `Prefs` stored in `server-state.conf` were not being updated with `Persist` state once the node had been succesfully logged in. Users have been working around this by finagling with the GUI to make it force a state rewrite. This patch makes that unnecessary by ensuring the required server mode state is updated when prefs are updated by the control client.

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).

Brad Fitzpatrick	4a82b317b7	ipn/{ipnlocal,localapi}: use strs.CutPrefix, add more domain validation ... The GitHub CodeQL scanner flagged the localapi's cert domain usage as a problem because user input in the URL made it to disk stat checks. The domain is validated against the ipnstate.Status later, and only authenticated root/configured users can hit this, but add some paranoia anyway.

Andrew Dunham	b8596f2a2f	net/dnsfallback: cache most recent DERP map on disk (#5545) ... This is especially helpful as we launch newer DERPs over time, and older clients have progressively out-of-date static DERP maps baked in. After this, as long as the client has successfully connected once, it'll cache the most recent DERP map it knows about.

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

Joe Tsai	32a1a3d1c0	util/deephash: avoid variadic argument for Update (#5372) ... Hashing []any is slow since hashing of interfaces is slow. Hashing of interfaces is slow since we pessimistically assume that cycles can occur through them and start cycle tracking. Drop the variadic signature of Update and fix callers to pass in an anonymous struct so that we are hashing concrete types near the root of the value tree.
