Anton Tolchanov	82b9689e25	ipn/ipnlocal: maintain a proxy handler per backend (#6804 ) By default, `http.Transport` keeps idle connections open hoping to re-use them in the future. Combined with a separate transport per request in HTTP proxy this results in idle connection leak. Fixes #6773	1 year ago
Brad Fitzpatrick	0f604923d3	ipn/ipnlocal: fix StatusWithoutPeers not populating parts of Status Fixes #4311 Change-Id: Iaae0615148fa7154f4ef8f66b455e3a6c2fa9df3 Co-authored-by: Claire Wang <claire@tailscale.com> Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
salman	2d271f3bd1	ipn/ipnlocal: disallow exit nodes from using exit nodes Nodes which have both -advertise-exit-node and -exit-node in prefs should continue have them until the next invocation of `tailscale up`. Updates #3569. Signed-off-by: salman <salman@tailscale.com>	2 years ago
Brad Fitzpatrick	1598cd0361	net/tsaddr: remove ContainsFunc helpers (they're now in x/exp/slices) x/exp/slices now has ContainsFunc (golang/go#53983) so we can delete our versions.

Brad Fitzpatrick	a277eb4dcf	ipn/ipnlocal: add missing context cancel If user's fn returned false and never canceled their ctx, we never stopped the NotifyWatchEngineUpdates goroutine.

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

Brad Fitzpatrick	6d012547b6	ipn/ipnlocal: use double dash flag style The Go style weirds people out so we try to stick to the more well-known double hyphen style in docs. Change-Id: Iad6db5c82cda37f6b7687eed7ecd9276f8fd94d6 Signed-off-by: Brad Fitzpatrick <bradfitz@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

Brad Fitzpatrick	ea25ef8236	util/set: add new set package for SetHandle type We use this pattern in a number of places (in this repo and elsewhere) and I was about to add a fourth to this repo which was crossing the line. Add this type instead so they're all the same. Also, we have another Set type (SliceSet, which tracks its keys in order) in another repo we can move to this package later.

Brad Fitzpatrick	8049053f86	ipn/*: make new WindowsUserID type to consolidate docs The "userID is empty everywhere but Windows" docs on lots of places but not everywhere while using just a string type was getting confusing. This makes a new type to wrap up those rules, however weird/historical they might be.

Brad Fitzpatrick	5676d201d6	ipn: add a WatchIPNBus option bit to subscribe to EngineStatus changes So GUI clients don't need to poll for it. We still poll internally (for now!) but that's still cheaper. And will get much cheaper later, without having to modify clients once they start sending this bit.

Maisem Ali	dd50dcd067	ipn/ipnlocal: handle untagging nodes better We would end up with duplicate profiles for the node as the UserID would have chnaged. In order to correctly deduplicate profiles, we need to look at both the UserID and the NodeID. A single machine can only ever have 1 profile per NodeID and 1 profile per UserID. Note: UserID of a Node can change when the node is tagged/untagged, and the NodeID of a device can change when the node is deleted so we need to check for both.

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
