Tom DNetto	2a0b5c21d2	net/dns/{., resolver}, wgengine: fix goroutine leak on shutdown Signed-off-by: Tom DNetto <tom@tailscale.com>	3 years ago
Tom DNetto	7f45734663	assorted: documentation and readability fixes This were intended to be pushed to #4408, but in my excitement I forgot to git push :/ better late than never. Signed-off-by: Tom DNetto <tom@tailscale.com>	3 years ago
Tom DNetto	9e77660931	net/tstun,wgengine/{.,netstack}: handle UDP magicDNS traffic in netstack This change wires netstack with a hook for traffic coming from the host into the tun, allowing interception and handling of traffic to quad-100. With this hook wired, magicDNS queries over UDP are now handled within netstack. The existing logic in wgengine to handle magicDNS remains for now, but its hook operates after the netstack hook so the netstack implementation takes precedence. This is done in case we need to support platforms with netstack longer than expected. Signed-off-by: Tom DNetto <tom@tailscale.com>	3 years ago
Tom DNetto	dc71d3559f	net/tstun,wgengine: split PreFilterOut into multiple hooks A subsequent commit implements handling of magicDNS traffic via netstack. Implementing this requires a hook for traffic originating from the host and hitting the tun, so we make another hook to support this. Signed-off-by: Tom DNetto <tom@tailscale.com>	3 years ago
Tom DNetto	9dee6adfab	cmd/tailscaled,ipn/ipnlocal,wgengine/...: pass dns.Manager into netstack Needed for a following commit which moves magicDNS handling into netstack. Signed-off-by: Tom DNetto <tom@tailscale.com>	3 years ago
Tom DNetto	5b85f848dd	net/dns,net/dns/resolver: refactor channels/magicDNS out of Resolver Moves magicDNS-specific handling out of Resolver & into dns.Manager. This greatly simplifies the Resolver to solely issuing queries and returning responses, without channels. Enforcement of max number of in-flight magicDNS queries, assembly of synthetic UDP datagrams, and integration with wgengine for recieving/responding to magicDNS traffic is now entirely in Manager. This path is being kept around, but ultimately aims to be deleted and replaced with a netstack-based path. This commit is part of a series to implement magicDNS using netstack.

Brad Fitzpatrick	a54671529b	client/tailscale: move API client for the control admin API This was work done Nov-Dec 2020 by @c22wen and @chungdaniel. This is just moving it to another repo.

Brad Fitzpatrick	e3619b890c	client/tailscale: rename tailscale.go -> localclient.go In prep for other stuff. Change-Id: I82c24946d062d668cab48ca6749776b6ae7025ac Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Maisem Ali	3012a2e1ca	ssh/tailssh,ipn/ipnlocal: terminate any active sessions on `up --ssh=false` Currently the ssh session isn't terminated cleanly, instead the packets are just are no longer routed to the in-proc SSH server. This makes it so that clients get a disconnection when the `RunSSH` pref changes to `false`. Updates #3802 Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
Mihai Parparita	2ec371fe8b	ipn: remove FakeExpireAfter Backend function No callers remain (last one was removed with tailscale/corp@1c095ae08f), and it's pretty esoteric. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	3 years ago
Aaron Klotz	d915e0054c	cmd/tailscaled: change Windows service shutdown and add optional event logging Once a stop request is received and the service updates its status to `svc.StopPending`, it should continue running until the shutdown sequence is complete, and then return out of `(*ipnService).Execute`, which automatically sends a `svc.Stopped` notification to Windows. To make this happen, I changed the loop so that it runs until `doneCh` is closed, and then returns. I also removed a spurious `svc.StopPending` notification that the Windows Service Control Manager might be interpreting as a request for more time to shut down. Finally, I added some optional logging that sends a record of service notifications to the Windows event log, allowing us to more easily correlate with any Service Control Manager errors that are sent to the same log.

Mihai Parparita	316523cc1e	ipn: remove enforceDefaults option from PrefsFromBytes The Mac client was using it, but it had the effect of the `RouteAll` ("Use Tailscale subnets") pref always being enabled at startup, regardless of the persisted value. enforceDefaults was added to handle cases from ~2 years ago where we ended up with persisted `"RouteAll": false` values in the keychain, but that should no longer be a concern. New users will get the default of it being enabled via `NewPrefs`. There will be a corresponding Mac client change to stop passing in enforceDefaults.

Brad Fitzpatrick	87ba528ae0	client/tailscale: move/copy all package funcs to new LocalClient type Remove all global variables, and clean up tsnet and cmd/tailscale's usage.

Brad Fitzpatrick	373176ea54	util/codegen: format generated code with goimports, not gofmt goimports is a superset of gofmt that also groups imports. (the goimports tool also adds/removes imports as needed, but that part is disabled here) Change-Id: Iacf0408dfd9497f4ed3da4fa50e165359ce38498 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	deb56f276e	Revert "api: document preauthorized auth keys" This reverts commit `dd6472d4e8`. Reason: it appears I was just really really wrong or confused. We added it to the old internal API used by the website instead, not to the "v2" API.

Maisem Ali	eff6a404a6	net/tshttpproxy: use http as the scheme for proxies Currently we try to use `https://` when we see `https_host`, however that doesn't work and results in errors like `Received error: fetch control key: Get "https://controlplane.tailscale.com/key?v=32": proxyconnect tcp: tls: first record does not look like a TLS handshake` This indiciates that we are trying to do a HTTPS request to a HTTP server.

Brad Fitzpatrick	1237000efe	control/controlhttp: don't assume port 80 upgrade response will work Just because we get an HTTP upgrade response over port 80, don't assume we'll be able to do bi-di Noise over it. There might be a MITM corp proxy or anti-virus/firewall interfering. Do a bit more work to validate the connection before proceeding to give up on the TLS port 443 dial.

James Tucker	1aa75b1c9e	wgengine/netstack: always set TCP keepalive Setting keepalive ensures that idle connections will eventually be closed. In userspace mode, any application configured TCP keepalive is effectively swallowed by the host kernel, and is not easy to detect. Failure to close connections when a peer tailscaled goes offline or restarts may result in an otherwise indefinite connection for any protocol endpoint that does not initiate new traffic. This patch does not take any new opinion on a sensible default for the keepalive timers, though as noted in the TODO, doing so likely deserves further consideration.

Brad Fitzpatrick	50eb8c5add	cmd/tailscale: mostly fix 'tailscale ssh' on macOS (sandbox) Still a little wonky, though.

Brad Fitzpatrick	21413392cf	safesocket: fix CLI on standalone mac GUI build Tested three macOS Tailscale daemons: - App Store (Network Extension) - Standalone (macsys) - tailscaled And two types of local IPC each: - IPN - HTTP And two CLI modes: - sandboxed (running the GUI binary as the CLI; normal way) - open source CLI hitting GUI (with #4525) Bonus: simplifies the code.

Maisem Ali	80ba161c40	wgengine/monitor: do not ignore changes to pdp_ip* One current theory (among other things) on battery consumption is that magicsock is resorting to using the IPv6 over LTE even on WiFi. One thing that could explain this is that we do not get link change updates for the LTE modem as we ignore them in this list. This commit makes us not ignore changes to `pdp_ip` as a test.
