Andrew Lytvynov	1f4a38ed49	clientupdate: add support for QNAP (#10179) ... Use the `qpkg_cli` to check for updates and install them. There are a couple special things about this compare to other updaters: * qpkg_cli can tell you when upgrade is available, but not what the version is * qpkg_cli --add Tailscale works for new installs, upgrades and reinstalling existing version; even reinstall of existing version takes a while Updates #10178 Signed-off-by: Andrew Lytvynov <awly@tailscale.com>	1 year ago

Andrew Lytvynov	55cd5c575b	ipn/localapi: only perform local-admin check in serveServeConfig (#10163) ... On unix systems, the check involves executing sudo, which is slow. Instead of doing it for every incoming request, move the logic into localapi serveServeConfig handler and do it as needed.

Will Norris	09de240934	ipn/ipnlocal: allow connecting to local web client ... The local web client has the same characteristic as tailscale serve, in that it needs a local listener to allow for connections from the local machine itself when running in kernel networking mode. This change renames and adapts the existing serveListener to allow it to be used by the web client as well. Updates tailscale/corp#14335 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago
Andrew Lytvynov	bff786520e	clientupdate,ipn/ipnlocal: fix c2n update on freebsd (#10168) ... The c2n part was broken because we were not looking up the tailscale binary for that GOOS. The rest of the update was failing at the `pkg upgrade` confirmation prompt. We also need to manually restart tailscaled after update.

Tom DNetto	11a20f371a	ipn/ipnlocal: fix nil control client panic while updating TKA head ... As part of tailnet-lock netmap processing, the LocalBackend mutex is unlocked so we can potentially make a network call. Its possible (during shutdown or while the control client is being reset) for b.cc to become nil before the lock is picked up again.

Tom DNetto	3496d62ed3	ipn/ipnlocal: add empty address to the app-connector localNets set ... App connectors handle DNS requests for app domains over PeerAPI, but a safety check verifies the requesting peer has at least permission to send traffic to 0.0.0.0:53 (or 2000:: for IPv6) before handling the DNS request. The correct filter rules are synthesized by the coordination server and sent down, but the address needs to be part of the 'local net' for the filter package to even bother checking the filter rules, so we set them here. See: https://github.com/tailscale/corp/issues/11961 for more information. Signed-off-by: Tom DNetto <tom@tailscale.com> Updates: ENG-2405	1 year ago
Charlotte Brandhorst-Satzkorn	f937cb6794	tailcfg,ipn,appc: add c2n endpoint for appc domain routes ...

Andrew Lytvynov	9b158db2c6	ipn/localapi: require root or sudo+operator access for SetServeConfig (#10142) ... For an operator user, require them to be able to `sudo tailscale` to use `tailscale serve`. This is similar to the Windows elevated token check.

Will Norris	6b956b49e0	client/web: add some security checks for full client ... Require that requests to servers in manage mode are made to the Tailscale IP (either ipv4 or ipv6) or quad-100. Also set various security headers on those responses. These might be too restrictive, but we can relax them as needed. Allow requests to /ok (even in manage mode) with no checks. This will be used for the connectivity check from a login client to see if the management client is reachable. Updates tailscale/corp#14335 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago
Aaron Klotz	fbc18410ad	ipn/ipnauth: improve the Windows token administrator check ... (*Token).IsAdministrator is supposed to return true even when the user is running with a UAC limited token. The idea is that, for the purposes of this check, we don't care whether the user is *currently* running with full Admin rights, we just want to know whether the user can *potentially* do so. We accomplish this by querying for the token's "linked token," which should be the fully-elevated variant, and checking its group memberships. We also switch ipn/ipnserver/(*Server).connIsLocalAdmin to use the elevation check to preserve those semantics for tailscale serve; I want the IsAdministrator check to be used for less sensitive things like toggling auto-update on and off.

Will Norris	658971d7c0	ipn/ipnlocal: serve web client on quad100 if enabled ... if the user pref and nodecap for the new web client are enabled, serve the client over requests to 100.100.100.100. Today, that is just a static page that lists the local Tailcale IP addresses. For now, this will render the readonly full management client, with an "access" button that sends the user through check mode. After completing check mode, they will still be in the read-only view, since they are not accessing the client over Tailscale. Instead, quad100 should serve the lobby client that has a "manage" button that will open the management client on the Tailscale IP (and trigger check mode). That is something we'll fix in a subsequent PR in the web client code itself. Updates tailscale/corp#14335 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago

Also starts filling this from the cli/web and ipn/ipnlocal callers. From cli/web this gets filled conditionally based on whether the preview web client node cap is set. If not set, the existing "legacy" client is served. If set, both a login/lobby and full management client are started (in "login" and "manage" modes respectively).

Sonia Appasamy	b370274b29	ipn/ipnlocal: pull CapabilityPreviewWebClient into webClientAtomicBool ... Now uses webClientAtomicBool as the source of truth for whether the web client should be running in tailscaled, with it updated when either the RunWebClient pref or CapabilityPreviewWebClient node capability changes.

An EmbeddedAppConnector is added that when configured observes DNS responses from the PeerAPI. If a response is found matching a configured domain, routes are advertised when necessary.

Sonia Appasamy	89953b015b	ipn/ipnlocal,client/web: add web client to tailscaled ... Allows for serving the web interface from tailscaled, with the ability to start and stop the server via localapi endpoints (/web/start and /web/stop). This will be used to run the new full management web client, which will only be accessible over Tailscale (with an extra auth check step over noise) from the daemon. This switch also allows us to run the web interface as a long-lived service in environments where the CLI version is restricted to CGI, allowing us to manage certain auth state in memory. ipn/ipnlocal/web is stubbed out in ipn/ipnlocal/web_stub for ios builds to satisfy ios restriction from adding "text/template" and "html/template" dependencies.

Aaron Klotz	95671b71a6	ipn, safesocket: use Windows token in LocalAPI ... On Windows, the idiomatic way to check access on a named pipe is for the server to impersonate the client on its current OS thread, perform access checks using the client's access token, and then revert the OS thread's access token back to its true self. The access token is a better representation of the client's rights than just a username/userid check, as it represents the client's effective rights at connection time, which might differ from their normal rights. This patch updates safesocket to do the aforementioned impersonation, extract the token handle, and then revert the impersonation. We retain the token handle for the remaining duration of the connection (the token continues to be valid even after we have reverted back to self). Since the token is a property of the connection, I changed ipnauth to wrap the concrete net.Conn to include the token. I then plumbed that change through ipnlocal, ipnserver, and localapi as necessary. I also added a PermitLocalAdmin flag to the localapi Handler which I intend to use for controlling access to a few new localapi endpoints intended for configuring auto-update.
