Andrea Gottardo	d6a8fb20e7	health: include DERP region name in bad derp notifications (#12530 ) Fixes tailscale/corp#20971 We added some Warnables for DERP failure situations, but their Text currently spits out the DERP region ID ("10") in the UI, which is super ugly. It would be better to provide the RegionName of the DERP region that is failing. We can do so by storing a reference to the last-known DERP map in the health package whenever we fetch one, and using it when generating the notification text. This way, the following message... > Tailscale could not connect to the relay server '10'. The server might be temporarily unavailable, or your Internet connection might be down. becomes: > Tailscale could not connect to the 'Seattle' relay server. The server might be temporarily unavailable, or your Internet connection might be down. which is a lot more user-friendly. Signed-off-by: Andrea Gottardo <andrea@gottardo.me>	5 months ago
Andrew Dunham	45d2f4301f	proxymap, various: distinguish between different protocols Previously, we were registering TCP and UDP connections in the same map, which could result in erroneously removing a mapping if one of the two connections completes while the other one is still active. Add a "proto string" argument to these functions to avoid this. Additionally, take the "proto" argument in LocalAPI, and plumb that through from the CLI and add a new LocalClient method.

Brad Fitzpatrick	86e0f9b912	net/ipset, wgengine/filter/filtertype: add split-out packages This moves NewContainsIPFunc from tsaddr to new ipset package. And wgengine/filter types gets split into wgengine/filter/filtertype, so netmap (and thus the CLI, etc) doesn't need to bring in ipset, bart, etc. Then add a test making sure the CLI deps don't regress.

Andrea Gottardo	a8ee83e2c5	health: begin work to use structured health warnings instead of strings, pipe changes into ipn.Notify (#12406 ) Updates tailscale/tailscale#4136 This PR is the first round of work to move from encoding health warnings as strings and use structured data instead. The current health package revolves around the idea of Subsystems. Each subsystem can have (or not have) a Go error associated with it. The overall health of the backend is given by the concatenation of all these errors. This PR polishes the concept of Warnable introduced by @bradfitz a few weeks ago. Each Warnable is a component of the backend (for instance, things like 'dns' or 'magicsock' are Warnables). Each Warnable has a unique identifying code. A Warnable is an entity we can warn the user about, by setting (or unsetting) a WarningState for it. Warnables have: - an identifying Code, so that the GUI can track them as their WarningStates come and go - a Title, which the GUIs can use to tell the user what component of the backend is broken - a Text, which is a function that is called with a set of Args to generate a more detailed error message to explain the unhappy state Additionally, this PR also begins to send Warnables and their WarningStates through LocalAPI to the clients, using ipn.Notify messages. An ipn.Notify is only issued when a warning is added or removed from the Tracker. In a next PR, we'll get rid of subsystems entirely, and we'll start using structured warnings for all errors affecting the backend functionality.

Irbe Krumina	bc53ebd4a0	ipn/{ipnlocal,localapi},net/netkernelconf,client/tailscale,cmd/containerboot: optionally enable UDP GRO forwarding for containers (#12410 ) Add a new TS_EXPERIMENTAL_ENABLE_FORWARDING_OPTIMIZATIONS env var that can be set for tailscale/tailscale container running as a subnet router or exit node to enable UDP GRO forwarding for improved performance. See https://tailscale.com/kb/1320/performance-best-practices#linux-optimizations-for-subnet-routers-and-exit-nodes This is currently considered an experimental approach; the configuration support is partially to allow further experimentation with containerized environments to evaluate the performance improvements.

Adrian Dewhurst	0219317372	ipn/ipnlocal: improve sticky last suggestion The last suggested exit node needs to be incorporated in the decision making process when a new suggestion is requested, but currently it is not quite right: it'll be used if the suggestion code has an error or a netmap is unavailable, but it won't be used otherwise. Instead, this makes the last suggestion into a tiebreaker when making a random selection between equally-good options. If the last suggestion does not make it to the final selection pool, then a different suggestion will be made. Since LocalBackend.SuggestExitNode is back to being a thin shim that sets up the parameters to suggestExitNode, it no longer needs a test. Its test was unable to be comprehensive anyway as the code being tested contains an uncontrolled random number generator.

Adrian Dewhurst	cf9f507d47	ipn/ipnlocal: only build allowed suggested node list once Rather than building a new suggested exit node set every time, compute it once on first use. Currently, syspolicy ensures that values do not change without a restart anyway. Since the set is being constructed in a separate func now, the test code that manipulates syspolicy can live there, and the TestSuggestExitNode can now run in parallel with other tests because it does not have global dependencies.

Andrew Lytvynov	bc4c8b65c7	ipn/ipnlocal: periodically run auto-updates when "offline" (#12118 ) When the client is disconnected from control for any reason (typically just turned off), we should still attempt to update if auto-updates are enabled.

Adrian Dewhurst	3bf2bddbb5	ipn/ipnlocal: improve testability of random node selection In order to test the sticky last suggestion code, a test was written for LocalBackend.SuggestExitNode but it contains a random number generator which makes writing comprehensive tests very difficult. This doesn't change how the last suggestion works, but it adds some infrastructure to make that easier in a later PR. This adds func parameters for the two randomized parts: breaking ties between DERP regions and breaking ties between nodes. This way tests can validate the entire list of tied options, rather than expecting a particular outcome given a particular random seed. As a result of this, the global random number generator can be used rather than seeding a local one each time. In order to see the tied nodes for the location based (i.e. Mullvad) case, pickWeighted needed to return a slice instead of a single arbitrary option, so there is a small change in how that works.

Anton Tolchanov	01847e0123	ipn/ipnlocal: discard node keys that have been rotated out A non-signing node can be allowed to re-sign its new node keys following key renewal/rotation (e.g. via `tailscale up --force-reauth`). To be able to do this, node's TLK is written into WrappingPubkey field of the initial SigDirect signature, signed by a signing node. The intended use of this field implies that, for each WrappingPubkey, we typically expect to have at most one active node with a signature tracing back to that key. Multiple valid signatures referring to the same WrappingPubkey can occur if a client's state has been cloned, but it's something we explicitly discourage and don't support: https://tailscale.com/s/clone This change propagates rotation details (wrapping public key, a list of previous node keys that have been rotated out) to netmap processing, and adds tracking of obsolete node keys that, when found, will get filtered out.

To test this, it also adds UDP support to tsdial.Dialer.UserDial and plumbs it through the localapi. Then an associated test to make sure the UDP functionality works from both sides.

Brad Fitzpatrick	e968b0ecd7	cmd/tailscale,controlclient,ipnlocal: fix 'up', deflake tests more The CLI's "up" is kinda chaotic and LocalBackend.Start is kinda chaotic and they both need to be redone/deleted (respectively), but this fixes some buggy behavior meanwhile. We were previously calling StartLoginInteractive (to start the controlclient's RegisterRequest) redundantly in some cases, causing test flakes depending on timing and up's weird state machine. We only need to call StartLoginInteractive in the client if Start itself doesn't. But Start doesn't tell us that. So cheat a bit and a put the information about whether there's a current NodeKey in the ipn.Status. It used to be accessible over LocalAPI via GetPrefs as a private key but we removed that for security. But a bool is fine.

Nick Khyl	caa3d7594f	ipn/ipnlocal, net/tsdial: plumb routes into tsdial and use them in UserDial We'd like to use tsdial.Dialer.UserDial instead of SystemDial for DNS over TCP. This is primarily necessary to properly dial internal DNS servers accessible over Tailscale and subnet routes. However, to avoid issues when switching between Wi-Fi and cellular, we need to ensure that we don't retain connections to any external addresses on the old interface. Therefore, we need to determine which dialer to use internally based on the configured routes. This plumbs routes and localRoutes from router.Config to tsdial.Dialer, and updates UserDial to use either the peer dialer or the system dialer, depending on the network address and the configured routes.
