Andrew Dunham	223126fe5b	cmd/derper, net/netcheck: add challenge/response to generate_204 endpoint The Lufthansa in-flight wifi generates a synthetic 204 response to the DERP server's /generate_204 endpoint. This PR adds a basic challenge/response to the endpoint; something sufficiently complicated that it's unlikely to be implemented by a captive portal. We can then check for the expected response to verify whether we're being MITM'd.

Anton Tolchanov	d499afac78	net/interfaces: improve default route detection Instead of treating any interface with a non-ifscope route as a potential default gateway, now verify that a given route is actually a default route (0.0.0.0/0 or ::/0).

Mihai Parparita	9d04ffc782	net/wsconn: add back custom wrapper for turning a websocket.Conn into a net.Conn We removed it in #4806 in favor of the built-in functionality from the nhooyr.io/websocket package. However, it has an issue with deadlines that has not been fixed yet (see nhooyr/websocket#350). Temporarily go back to using a custom wrapper (using the fix from our fork) so that derpers will stop closing connections too aggressively.

Xe Iaso	86c5bddce2	tsnet/examples/tshello: update example for LocalClient method (#5966 ) Before this would silently fail if this program was running on a machine that was not already running Tailscale.

Joe Tsai	9116e92718	cmd/netlogfmt: new package to pretty print network traffic logs (#5930 ) This package parses a JSON stream of netlog.Message from os.Stdin and pretty prints the contents as a stream of tables.

Joe Tsai	9ee3df02ee	wgengine/magicsock: remove endpoint.wgEndpoint (#5911 ) This field seems seldom used and the documentation is wrong. It is simpler to just derive its original value dynamically when endpoint.DstToString is called. This method is potentially used by wireguard-go, but not in any code path is performance sensitive. All calls to it use it in conjunction with fmt.Printf, which is going to be slow anyways since it uses Go reflection. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago

Brad Fitzpatrick	a04f1ff9e6	logtail: default to 2s log flush delay on all platforms Per chat. This is close enough to realtime but massively reduces number of HTTP requests.

Mihai Parparita	63ad49890f	cmd/tsconnect: pre-compress main.wasm when building the NPM package This way we can do that once (out of band, in the GitHub action), instead of increasing the time of each deploy that uses the package. .wasm is removed from the list of automatically pre-compressed extensions, an OSS bump and small change on the corp side is needed to make use of this change.

Tom DNetto	a515fc517b	ipn/ipnlocal: make tkaSyncIfNeeded exclusive with a mutex Running corp/ipn#TestNetworkLockE2E has a 1/300 chance of failing, and deskchecking suggests thats whats happening are two netmaps are racing each other to be processed through tkaSyncIfNeededLocked. This happens in the first place because we release b.mu during network RPCs. To fix this, we make the tka sync logic an exclusive section, so two netmaps will need to wait for tka sync to complete serially (which is what we would want anyway, as the second run through probably wont need to sync).

James Tucker	539c073cf0	wgengine/magicsock: set UDP socket buffer sizes to 7MB - At high data rates more buffer space is required in order to avoid packet loss during any cause of delay. - On slower machines more buffer space is required in order to avoid packet loss while decryption & tun writing is underway. - On higher latency network paths more buffer space is required in order to overcome BDP. - On Linux set with SO_*BUFFORCE to bypass net.core.{r,w}mem_max. - 7MB is the current default maximum on macOS 12.6 - Windows test is omitted, as Windows does not support getsockopt for these options.

Joe Tsai	a1a43ed266	wgengine/netlog: add support for magicsock statistics (#5913 ) This sets up Logger to handle statistics at the magicsock layer, where we can correlate traffic between a particular tailscale IP address and any number of physical endpoints used to contact the node that hosts that tailscale address. We also export Message and TupleCounts to better document the JSON format that is being sent to the logging infrastructure. This commit does NOT yet enable the actual logging of magicsock statistics.
