Will Norris	d74c771fda	client/web: always use new web client; remove old client This uses the new react-based web client for all builds, not just with the --dev flag. If the web client assets have not been built, the client will serve a message that Tailscale was built without the web client, and link to build instructions. Because we will include the web client in all of our builds, this should only be seen by developers or users building from source. (And eventually this will be replaced by attempting to download needed assets as runtime.) We do now checkin the build/index.html file, which serves the error message when assets are unavailable. This will also eventually be used to trigger in CI when new assets should be built and uploaded to a well-known location.

Andrew Dunham	c86a610eb3	cmd/tailscale, net/portmapper: add --log-http option to "debug portmap" This option allows logging the raw HTTP requests and responses that the portmapper Client makes when using UPnP. This can be extremely helpful when debugging strange UPnP issues with users' devices, and might allow us to avoid having to instruct users to perform a packet capture.

Maisem Ali	c8dea67cbf	cmd/k8s-operator: add support for Ingress resources Previously, the operator would only monitor Services and create a Tailscale StatefulSet which acted as a L3 proxy which proxied traffic inbound to the Tailscale IP onto the services ClusterIP. This extends that functionality to also monitor Ingress resources where the `ingressClassName=tailscale` and similarly creates a Tailscale StatefulSet, acting as a L7 proxy instead. Users can override the desired hostname by setting: ``` - tls hosts: - "foo" ``` Hostnames specified under `rules` are ignored as we only create a single host. This is emitted as an event for users to see. Fixes #7895 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago
Maisem Ali	320f77bd24	cmd/containerboot: add support for setting ServeConfig This watches the provided path for a JSON encoded ipn.ServeConfig. Everytime the file changes, or the nodes FQDN changes it reapplies the ServeConfig. At boot time, it nils out any previous ServeConfig just like tsnet does. As the ServeConfig requires pre-existing knowledge of the nodes FQDN to do SNI matching, it introduces a special `${TS_CERT_DOMAIN}` value in the JSON file which is replaced with the known CertDomain before it is applied.

Denton Gentry	24d41e4ae7	cmd/sniproxy: add port forwarding and prometheus metrics 1. Add TCP port forwarding.

You've successfully authenticated, but GitHub does not provide shell access. % ssh -i ~/.ssh/id_ecdsa.pem -T git@100.65.x.y Hi GitHubUser!

Aaron Klotz	5fb1695bcb	util/osdiag, util/osdiag/internal/wsc: add code to probe the Windows Security Center for installed software The Windows Security Center is a component that manages the registration of security products on a Windows system. Only products that have obtained a special cert from Microsoft may register themselves using the WSC API. Practically speaking, most vendors do in fact sign up for the program as it enhances their legitimacy. From our perspective, this is useful because it gives us a high-signal source of information to query for the security products installed on the system. I've tied this query into the osdiag package and is run during bugreports. It uses COM bindings that were automatically generated by my prototype metadata processor, however that program still has a few bugs, so I had to make a few manual tweaks. I dropped those binding into an internal package because (for the moment, at least) they are effectively purpose-built for the osdiag use case. We also update the wingoes dependency to pick up BSTR.

Brad Fitzpatrick	4511e7d64e	ipn/ipnstate: add PeerStatus.AltSharerUserID, stop mangling Node.User In `b987b2ab18` (2021-01-12) when we introduced sharing we mapped the sharer to the userid at a low layer, mostly to fix the display of "tailscale status" and the client UIs, but also some tests. The commit earlier today, `7dec09d169`, removed the 2.5yo option to let clients disable that automatic mapping, as clearly we were never getting around to it. This plumbs the Sharer UserID all the way to ipnstatus so the CLI itself can choose to print out the Sharer's identity over the node's original owner. Then we stop mangling Node.User and let clients decide how they want to render things. To ease the migration for the Windows GUI (which currently operates on tailcfg.Node via the NetMap from WatchIPNBus, instead of PeerStatus), a new method Node.SharerOrUser is added to do the mapping of Sharer-else-User.

Charlotte Brandhorst-Satzkorn	35bdbeda9f	cli: introduce exit-node subcommand to list and filter exit nodes This change introduces a new subcommand, `exit-node`, along with a subsubcommand of `list` and a `--filter` flag. Exit nodes without location data will continue to be displayed when `status` is used. Exit nodes with location data will only be displayed behind `exit-node list`, and in status if they are the active exit node. The `filter` flag can be used to filter exit nodes with location data by country. Exit nodes with Location.Priority data will have only the highest priority option for each country and city listed. For countries with multiple cities, a <Country> <Any> option will be displayed, indicating the highest priority node within that country.

Joe Tsai	84c99fe0d9	logtail: be less aggressive about re-uploads (#8117 ) The retry logic was pathological in the following ways: * If we restarted the logging service, any pending uploads would be placed in a retry-loop where it depended on backoff.Backoff, which was too aggresive. It would retry failures within milliseconds, taking at least 10 retries to hit a delay of 1 second. * In the event where a logstream was rate limited, the aggressive retry logic would severely exacerbate the problem since each retry would also log an error message. It is by chance that the rate of log error spam does not happen to exceed the rate limit itself. We modify the retry logic in the following ways: * We now respect the "Retry-After" header sent by the logging service. * Lacking a "Retry-After" header, we retry after a hard-coded period of 30 to 60 seconds. This avoids the thundering-herd effect when all nodes try reconnecting to the logging service at the same time after a restart. * We do not treat a status 400 as having been uploaded. This is simply not the behavior of the logging service. Updates #tailscale/corp#11213 Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago

When an address is initially selected, we also initiate a new ICMP ping to the endpoints addresses to determine which endpoint offers the best latency. This information is then used to update which endpoint we should be using based on the best possible route. If the latency is the same for a IPv4 and an IPv6 address, IPv6 will be used.

Aaron Klotz	90fd04cbde	ipn/ipnlocal, util/winutil/policy: modify Windows profile migration to load legacy prefs from within tailscaled I realized that a lot of the problems that we're seeing around migration and LocalBackend state can be avoided if we drive Windows pref migration entirely from within tailscaled. By doing it this way, tailscaled can automatically perform the migration as soon as the connection with the client frontend is established. Since tailscaled is already running as LocalSystem, it already has access to the user's local AppData directory. The profile manager already knows which user is connected, so we simply need to resolve the user's prefs file and read it from there. Of course, to properly migrate this information we need to also check system policies. I moved a bunch of policy resolution code out of the GUI and into a new package in util/winutil/policy.

Mihai Parparita	02582083d5	cmd/tsconnect: allow root directory to be passed in #7339 changed the root directory logic to find the ancestor of the cwd with a go.mod file. This works when running the the binary from this repo directly, but breaks when we're a dependency in another repo. Allow the directory to be passed in via a -rootdir flag (the repo that depends on it can then use `go list -m -f '{{.Dir}}' tailscale.com` or similar to pass in the value).

Maisem Ali	985535aebc	net/tstun,wgengine/*: add support for NAT to routes This adds support to make exit nodes and subnet routers work when in scenarios where NAT is required. It also updates the NATConfig to be generated from a `wgcfg.Config` as that handles merging prefs with the netmap, so it has the required information about whether an exit node is already configured and whether routes are accepted.
