2025-05-14feature/taildrop,ipn/ipn{ext,local}: initialize taildrop for initial profileNick Khyl2-1/+4
Currently, LocalBackend/ExtensionHost doesn't invoke the profile change callback for the initial profile. Since the initial profile may vary depending on loaded extensions and applied policy settings, it can't be reliably determined until all extensions are initialized. Additionally, some extensions may asynchronously trigger a switch to the "best" profile (based on system state and policy settings) during initialization. We intended to address these issues as part of the ongoing profileManager/LocalBackend refactoring, but the changes didn't land in time for the v1.84 release and the Taildrop refactoring. In this PR, we update the Taildrop extension to retrieve the current profile at initialization time and handle it as a profile change. We also defer extension initialization until LocalBackend has started, since the Taildrop extension already relies on this behavior (e.g., it requires clients to call SetDirectFileRoot before Init).

2025-05-09net/udprelay{/endpoint}, all: move ServerEndpoint to independent pkg (#15934)Jordan Whited2-4/+5
ServerEndpoint will be used within magicsock and potentially elsewhere, which should be possible without needing to import the server implementation itself. Updates tailscale/corp#27502 Signed-off-by: Jordan Whited <jordan@tailscale.com>
2025-05-08feature/taildrop, ipn/ipnlocal: remove leftover dup calls to osshareBrad Fitzpatrick1-0/+9
I'd moved the osshare calls to feature/taildrop hooks, but forgot to remove them from ipnlocal, or lost them during a rebase. But then I noticed cmd/tailscaled also had some, so turn those into a hook.

2025-05-01feature/taildrop: add integration testBrad Fitzpatrick2-5/+183
Taildrop has never had an end-to-end test since it was introduced. This adds a basic one. It caught two recent refactoring bugs & one from 2022 (0f7da5c7dc0). This is prep for moving the rest of Taildrop out of LocalBackend, so we can do more refactorings with some confidence.

2025-04-25feature,ipn/ipnlocal: add profileManager.StateChangeHookNick Khyl1-0/+6
We update profileManager to allow registering a single state (profile+prefs) change hook. This is to invert the dependency between the profileManager and the LocalBackend, so that instead of LocalBackend asking profileManager for the state, we can have profileManager call LocalBackend when the state changes. We also update feature.Hook with a new (*feature.Hook).GetOk method to avoid calling both IsSet and Get. Updates tailscale/corp#28014 Updates #12614 Signed-off-by: Nick Khyl <nickk@tailscale.com>
2025-04-25ipn/ipnext: remove some interface indirection to add hooksBrad Fitzpatrick2-1/+19
Now that 25c4dc5fd70 removed unregistering hooks and made them into slices, just expose the slices and remove the setter funcs. This removes boilerplate ceremony around adding new hooks. This does export the hooks and make them mutable at runtime in theory, but that'd be a data race. If we really wanted to lock it down in the future we could make the feature.Hooks slice type be an opaque struct with an All() iterator and a "frozen" bool and we could freeze all the hooks after init. But that doesn't seem worth it. This means that hook registration is also now all in one place, rather than being mixed into ProfilesService vs ipnext.Host vs FooService vs BarService. I view that as a feature. When we have a ton of hooks and the list is long, then we can rearrange the fields in the Hooks struct as needed, or make sub-structs, or big comments.

2025-04-16feature/taildrop: start moving Taildrop out of LocalBackendBrad Fitzpatrick6-0/+1236
This adds a feature/taildrop package, a ts_omit_taildrop build tag, and starts moving code to feature/taildrop. In some cases, code remains where it was but is now behind a build tag. Future changes will move code to an extension and out of LocalBackend, etc. Updates #12614 Change-Id: Idf96c61144d1a5f707039ceb2ff59c99f5c1642f Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2025-04-16feature/{condregister,relayserver}: implement the skeleton for the ↵Jordan Whited2-0/+162
relayserver feature (#15699) This feature is "registered" as an ipnlocal.Extension, and conditionally linked depending on GOOS and ts_omit_relayserver build tag. The feature is not linked on iOS in attempt to limit the impact to binary size and resulting effect of pushing up against NetworkExtension limits. Eventually we will want to support the relay server on iOS, specifically on the Apple TV. Apple TVs are well-fitted to act as underlay relay servers as they are effectively always-on servers. This skeleton begins to tie a PeerAPI endpoint to a net/udprelay.Server. The PeerAPI endpoint is currently no-op as extension.shouldRunRelayServer() always returns false. Follow-up commits will implement extension.shouldRunRelayServer(). Updates tailscale/corp#27502 Signed-off-by: Jordan Whited <jordan@tailscale.com>
2025-01-24feature/capture: move packet capture to feature/*, out of iOS + CLIBrad Fitzpatrick4-0/+433
We had the debug packet capture code + Lua dissector in the CLI + the iOS app. Now we don't, with tests to lock it in. As a bonus, tailscale.com/net/packet and tailscale.com/net/flowtrack no longer appear in the CLI's binary either. A new build tag ts_omit_capture disables the packet capture code and was added to build_dist.sh's --extra-small mode.

Still behind the same ts_omit_tap build tag. See #14738 for background on the pattern. Updates #12614 Change-Id: I03fb3d2bf137111e727415bd8e713d8568156ecc Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2025-01-22feature/*: make Wake-on-LAN conditional, start supporting modular featuresBrad Fitzpatrick4-0/+273
This pulls out the Wake-on-LAN (WoL) code out into its own package (feature/wakeonlan) that registers itself with various new hooks around tailscaled. Then a new build tag (ts_omit_wakeonlan) causes the package to not even be linked in the binary. Ohter new packages include: * feature: to just record which features are loaded. Future: dependencies between features. * feature/condregister: the package with all the build tags that tailscaled, tsnet, and the Tailscale Xcode project extension can empty (underscore) import to load features as a function of the defined build tags. Future commits will move of our "ts_omit_foo" build tags into this style. Updates #12614 Change-Id: I9c5378dafb1113b62b816aabef02714db3fc9c4a Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
