2024-11-11all: use iterators over slice views moreBrad Fitzpatrick1-8/+7
This gets close to all of the remaining ones. Updates #12912 Change-Id: I9c672bbed2654a6c5cab31e0cbece6c107d8c6fa Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2024-06-16net/ipset, wgengine/filter/filtertype: add split-out packagesBrad Fitzpatrick1-2/+2
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. Updates #1278 Change-Id: Ia246d6d9502bbefbdeacc4aef1bed9c8b24f54d5 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2024-05-17ipn,wgengine: remove vestigial Prefs.AllowSingleHostsBrad Fitzpatrick1-1/+1
It was requested by the first customer 4-5 years ago and only used for a brief moment of time. We later added netmap visibility trimming which removes the need for this. It's been hidden by the CLI for quite some time and never documented anywhere else. This keeps the CLI flag, though, out of caution. It just returns an error if it's set to anything but true (its default). Fixes #12058 Change-Id: I7514ba572e7b82519b04ed603ff9f3bdbaecfda7 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>

2024-03-22ipn/ipnlocal, types/netmap: replace hasCapability with set lookup on NetworkMapBrad Fitzpatrick1-0/+7
When node attributes were super rare, the O(n) slice scans looking for node attributes was more acceptable. But now more code and more users are using increasingly more node attributes. Time to make it a map. Noticed while working on tailscale/corp#17879 Updates #cleanup Change-Id: Ic17c80341f418421002fbceb47490729048756d2 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>

2023-12-18ipn: apply tailnet-wide default for auto-updates (#10508)Andrew Lytvynov2-1/+6
When auto-update setting in local Prefs is unset, apply the tailnet default value from control. This only happens once, when we apply the default (or when the user manually overrides it), tailnet default no longer affects the node. Updates #16244 Signed-off-by: Andrew Lytvynov <awly@tailscale.com>
2023-11-17ipn/ipnlocal,cmd/tailscale: persist tailnet name in user profileMarwan Sulaiman1-0/+10
This PR starts to persist the NetMap tailnet name in SetPrefs so that tailscaled clients can use this value to disambiguate fast user switching from one tailnet to another that are under the same exact login. We will also try to backfill this information during backend starts and profile switches so that users don't have to re-authenticate their profile. The first client to use this new information is the CLI in 'tailscale switch -list' which now uses text/tabwriter to display the ID, Tailnet, and Account. Since account names are ambiguous, we allow the user to pass 'tailscale switch ID' to specify the exact tailnet they want to switch to.

2023-09-18tailcfg: add NodeCapMapMaisem Ali1-1/+6
Like PeerCapMap, add a field to `tailcfg.Node` which provides a map of Capability to raw JSON messages which are deferred to be parsed later by the application code which cares about the specific capabilities. This effectively allows us to prototype new behavior without having to commit to a schema in tailcfg, and it also opens up the possibilities to develop custom behavior in tsnet applications w/o having to plumb through application specific data in the MapResponse.

2023-09-18types/netmap: remove NetworkMap.{Addresses,MachineStatus}Brad Fitzpatrick1-39/+5
And convert all callers over to the methods that check SelfNode. Now we don't have multiple ways to express things in tests (setting fields on SelfNode vs NetworkMap, sometimes inconsistently) and don't have multiple ways to check those two fields (often only checking one or the other).

2023-09-17ipn/ipnlocal: keep internal map updated of latest Nodes post mutationsBrad Fitzpatrick1-0/+23
We have some flaky integration tests elsewhere that have no one place to ask about the state of the world. This makes LocalBackend be that place (as it's basically there anyway) but doesn't yet add the ForTest accessor method. This adds a LocalBackend.peers map[NodeID]NodeView that is incrementally updated as mutations arrive. And then we start moving away from using NetMap.Peers at runtime (UpdateStatus no longer uses it now). And remove another copy of NodeView in the LocalBackend nodeByAddr map. Change that to point into b.peers instead. Future changes will then start streaming whole-node-granularity peer change updates to WatchIPNBus clients, tracking statefully per client what each has seen. This will get the GUI clients from receiving less of a JSON storm of updates all the time.

2023-09-17types/netmap: start phasing out Addresses, add GetAddresses methodBrad Fitzpatrick1-1/+18
NetworkMap.Addresses is redundant with the SelfNode.Addresses. This works towards a TODO to delete NetworkMap.Addresses and replace it with a method. This is similar to #9389.

So if the control plane knows that something's broken about the node, it can include problem(s) in MapResponse and "tailscale status" will show it. (and GUIs in the future, as it's in ipnstate.Status/JSON) This also bumps the MapRequest.Version, though it's not strictly required. Doesn't hurt.
