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	6d76764f37	ipn/ipnlocal: fix taildrop target list UI bug The macOS and iOS apps that used the /localapi/v0/file-targets handler were getting too many candidate targets. They wouldn't actually accept the file. This is effectively just a UI glitch in the wrong hosts being listed as valid targets from the source side.

Tom DNetto	8602061f32	ipn/ipnlocal,tka: Fix bugs found by integration testing * tka.State.staticValidateCheckpoint could call methods on a contained key prior to calling StaticValidate on that key * Remove broken backoff / RPC retry logic from tka methods in ipn/ipnlocal, to be fixed at a later time * Fix NetworkLockModify() which would attempt to take b.mu twice and deadlock, remove now-unused dependence on netmap * Add methods on ipnlocal.LocalBackend to be used in integration tests * Use TAILSCALE_USE_WIP_CODE as the feature flag so it can be manipulated in tests Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago

Brad Fitzpatrick	65c24b6334	envknob: generalize Windows tailscaled-env.txt support ipnserver previously had support for a Windows-only environment variable mechanism that further only worked when Windows was running as a service, not from a console. But we want it to work from tailscaed too, and we want it to work on macOS and Synology. So move it to envknob, now that envknob can change values at runtime post-init. A future change will wire this up for more platforms, and do something more for CLI flags like --port, which the bug was originally about.

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.

Brad Fitzpatrick	45a3de14a6	cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support As noted in #5617, our documented method of blocking log.tailscale.io DNS no longer works due to bootstrap DNS. Instead, provide an explicit flag (--no-logs-no-support) and/or env variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher uploads. It also sets a bit on Hostinfo to say that the node is in that mode so we can end any support tickets from such nodes more quickly. This does not yet provide an easy mechanism for users on some platforms (such as Windows, macOS, Synology) to set flags/env. On Linux you'd used /etc/default/tailscaled typically. Making it easier to set flags for other platforms is tracked in #5114.

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.

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.

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.
