Denton Gentry	0687195bee	logpolicy: put Synology logs buffer in /tmp Ongoing log writing keeps the spinning disks from hibernating. Fixes https://github.com/tailscale/tailscale/issues/3551 Tested on DSM6 and DSM7. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
Brad Fitzpatrick	fbc079d82d	ipn/ipnlocal: prevent attempting to run SSH on Synology for now On DSM7 as a non-root user it'll run into problems. And we haven't tested on DSM6, even though it might work, but I doubt it.

Brad Fitzpatrick	a9b4bf1535	ipn/ipnserver, cmd/tailscaled: fix peerapi on Windows We weren't wiring up netstack.Impl to the LocalBackend in some cases on Windows.

Mihai Parparita	a9f32656f5	control/controlhttp: allow client and server to communicate over WebSockets We can't do Noise-over-HTTP in Wasm/JS (because we don't have bidirectional communication), but we should be able to do it over WebSockets. Reuses derp WebSocket support that allows us to turn a WebSocket connection into a net.Conn. Updates #3157 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	3 years ago
Maisem Ali	80157f3f37	net/dns/resolver: add support for <IPv4>.via-<site-id> Currently we only support "via-<site-id>.<IPv4>", however that does not work with Google Chrome which parses `http://via-1.10.0.0.1` as a search string and not as a URL. This commit introduces "<IPv4>.via-<site-id>" (`http://10.0.0.1.via-1`) which is parsed correctly by Chrome. Updates #3616 Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago

Maisem Ali	67325d334e	cmd/tailscale/cli: add lose-ssh risk This makes it so that the user is notified that the action they are about to take may result in them getting disconnected from the machine. It then waits for 5s for the user to maybe Ctrl+C out of it. It also introduces a `--accept-risk=lose-ssh` flag for automation, which allows the caller to pre-acknowledge the risk. The two actions that cause this are: - updating `--ssh` from `true` to `false` - running `tailscale down` Updates #3802 Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago

Maisem Ali	575aacb1e2	ssh/tailssh: terminate sessions on stdout copy failures Currently, killing a SCP copy with a Ctrl+C leaves the session hanging even though the stdout copy goroutine fails with an io.EOF. Taking a step back, when we are unable to send any more data back to the client we should just terminate the session as the client will stop getting any response from the server anyways. Updates #3802 Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
Maisem Ali	7cd8c3e839	ssh/tailssh: terminate sessions when tailscaled shutsdown Ideally we would re-establish these sessions when tailscaled comes back up, however we do not do that yet so this is better than leaking the sessions.

Tom	2903d42921	wgengine/router: delete hardcoded link-local address on Windows (#4740 ) Fixes #4647 It seems that Windows creates a link-local address for the TUN driver, seemingly based on the (fixed) adapter GUID. This results in a fixed MAC address, which for some reason doesn't handle loopback correctly. Given the derived link-local address is preferred for lookups (thanks LLMNR), traffic which addresses the current node by hostname uses this broken address and never works. To address this, we remove the broken link-local address from the wintun adapter. Signed-off-by: Tom DNetto <tom@tailscale.com>	3 years ago
Aaron Klotz	b005b79236	net/dns, paths, util/winutil: change net/dns/windowsManager NRPT management to support more than 50 domains. AFAICT this isn't documented on MSDN, but based on the issue referenced below, NRPT rules are not working when a rule specifies > 50 domains. This patch modifies our NRPT rule generator to split the list of domains into chunks as necessary, and write a separate rule for each chunk. For compatibility reasons, we continue to use the hard-coded rule ID, but as additional rules are required, we generate new GUIDs. Those GUIDs are stored under the Tailscale registry path so that we know which rules are ours. I made some changes to winutils to add additional helper functions in support of both the code and its test: I added additional registry accessors, and also moved some token accessors from paths to util/winutil.

Denton Gentry	0f95eaa8bb	scripts/installer: fix elementaryOS `c2b907c965` moved UBUNTU_VERSION out of the ubuntu case and into linuxmint, but linuxmint wasn't the only Ubuntu-based system which needed it. Restore UBUNTU_VERSION handling in the ubuntu case. Break elementaryOS out into its own handling so we can get the version number handling correct for keyring support. Tested on an elementaryOS 6.1 VM. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago

Aaron Klotz	c163b2a3f1	util/winutil, util/winutil/vss: remove winrestore and vss as they are unnecessary. I wrote this code way back at the beginning of my tenure at Tailscale when we had concerns about needing to restore deleted machine keys from backups. We never ended up using this functionality, and the code is now getting in the way, so we might as well remove it. Signed-off-by: Aaron Klotz <aaron@tailscale.com>	3 years ago

Tom	acfe5bd33b	net/dns{., resolver}: time out DNS queries after 10 seconds (#4690 ) Fixes https://github.com/tailscale/corp/issues/5198 The upstream forwarder will block indefinitely on `udpconn.ReadFrom` if no reply is recieved, due to the lack of deadline on the connection object. There still isn't a deadline on the connection object, but the automatic closing of the context on deadline expiry will close the connection via `closeOnCtxDone`, unblocking the read and resulting in a normal teardown.
