Charlotte Brandhorst-Satzkorn	7ee3068f9d	words: after a Series of discussions, Bees should be included (#4606) ... There has been a lot of talk about Bees at Tailscale recently, and naturally, with it being Tailscale, we thought to ourselves: Do Bees have a tail and/or scales? Tailscale has a long track record of scientific rigor around the validity of the inclusions on the tails and scales list, and this time will be no exception. Our research has found that Bees, in particular the Honey Bee, produces wax scales on their abdomens and thus should be included. As for tails; 'Stabby-tails' - Tailscale Employee, 2022 No further justification needed, it will be included. This change includes Bee in both tails.txt and scales.txt.

Maisem Ali	c60cbca371	control/controlclient: store netinfo and hostinfo separately ... Currently, when SetNetInfo is called it sets the value on hostinfo.NetInfo. However, when SetHostInfo is called it overwrites the hostinfo field which may mean it also clears out the NetInfo it had just received. This commit stores NetInfo separately and combines it into Hostinfo as needed so that control is always notified of the latest values. Also, remove unused copies of Hostinfo from ipn.Status and controlclient.Auto. Updates #tailscale/corp#4824 (maybe fixes) Signed-off-by: Maisem Ali <maisem@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.

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.

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.

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.
