shayne	4471e403aa	ipn/ipnlocal: [serve] listen on all-interfaces for macOS sandboxed (#6771 ) On macOS (AppStore and macsys), we need to bind to ""/all-interfaces due to the network sandbox. Ideally we would only bind to the Tailscale interface, but macOS errors out if we try to to listen on privileged ports binding only to a specific interface. We also implement the lc.Control hook, same as we do for peerapi. It doesn't solve our problem but it's better that we do and would likely be required when Apple gets around to fixing per-interface priviliged port binding.

salman	eec734a578	ipn/{ipnlocal,localapi}: ensure watcher is installed before /watch-ipn-bus/ responds with 200 This change delays the first flush in the /watch-ipn-bus/ handler until after the watcher has been successfully installed on the IPN bus. It does this by adding a new onWatchAdded callback to LocalBackend.WatchNotifications(). Without this, the endpoint returns a 200 almost immediatly, and only then installs a watcher for IPN events. This means there's a small window where events could be missed by clients after calling WatchIPNBus(). Fixes tailscale/corp#8594. Signed-off-by: salman <salman@tailscale.com>	2 years ago
Andrew Dunham	3a018e51bb	ipn/ipnlocal: move handling of expired nodes to LocalBackend In order to be able to synthesize a new NetMap when a node expires, have LocalBackend start a timer when receiving a new NetMap that fires slightly after the next node expires. Additionally, move the logic that updates expired nodes into LocalBackend so it runs on every netmap (whether received from controlclient or self-triggered).

Tom DNetto	f1ab11e961	ipn/ipnlocal,tailcfg: introduce capability to gate TKA init paths Previously, `TAILSCALE_USE_WIP_CODE` was needed to hit a bunch of the TKA paths. With this change: - Enablement codepaths (NetworkLockInit) and initialization codepaths (tkaBootstrapFromGenesisLocked via tkaSyncIfNeeded) require either the WIP envknob or CapabilityTailnetLockAlpha. - Normal operation codepaths (tkaSyncIfNeeded, tkaFilterNetmapLocked) require TKA to be initialized, or either-or the envknob / capability. - Auxillary commands (ie: changing tka keys) require TKA to be initialized. The end result is that it shouldn't be possible to initialize TKA (or subsequently use any of its features) without being sent the capability or setting the envknob on tailscaled yourself. I've also pulled out a bunch of unnecessary checks for CanSupportNetworkLock(). Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago

Aaron Klotz	659e7837c6	health, ipn/ipnlocal: when -no-logs-no-support is enabled, deny access to tailnets that have network logging enabled We want users to have the freedom to start tailscaled with `-no-logs-no-support`, but that is obviously in direct conflict with tailnets that have network logging enabled. When we detect that condition, we record the issue in health, notify the client, set WantRunning=false, and bail. We clear the item in health when a profile switch occurs, since it is a per-tailnet condition that should not propagate across profiles. Signed-off-by: Aaron Klotz <aaron@tailscale.com>	2 years ago
