Andrew Dunham	8a9888aea9	net/interfaces: don't dereference null pointer if no destination/netmask Fixes #6065 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: I7159b8cbb8d5f47c0668cf83e59167f182f1defd (cherry picked from commit `95f3dd1346`)	2 years ago
Jordan Whited	5bdf8e21c8	wgengine/netstack: enable TCP SACK (#6066 ) TCP selective acknowledgement can improve throughput by an order of magnitude in the presence of loss. Signed-off-by: Jordan Whited <jordan@tailscale.com> (cherry picked from commit `a471681e28`)	2 years ago
Peter Cai	78c60b49f7	net/dnscache: Handle 4-in-6 addresses in DNS responses On Android, the system resolver can return IPv4 addresses as IPv6-mapped addresses (i.e. `::ffff:a.b.c.d`). After the switch to `net/netip` (`19008a3`), this case is no longer handled and a response like this will be seen as failure to resolve any IPv4 addresses. Handle this case by simply calling `Unmap()` on the returned IPs. Fixes #5698. Signed-off-by: Peter Cai <peter@typeblog.net> (cherry picked from commit `4597ec1037`)	2 years ago

Maisem Ali	8023971bff	wgengine/router: [linux] add before deleting interface addrs Deleting may temporarily result in no addrs on the interface, which results in all other rules (like routes) to get dropped by the OS. I verified this fixes the problem. Signed-off-by: Maisem Ali <maisem@tailscale.com> (cherry picked from commit `74637f2c15`)	2 years ago
Andrew Dunham	0cc397e96d	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. Follow-up to #5601 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: I94a68c9a16a7be7290200eea6a549b64f02ff48f (cherry picked from commit `223126fe5b`)	2 years ago
Anton Tolchanov	46235b790d	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). Fixes #5879 Signed-off-by: Anton Tolchanov <anton@tailscale.com> (cherry picked from commit `d499afac78`)	2 years ago
Anton Tolchanov	b6ce364bf7	net/interfaces: deduplicate route table parsing on Darwin and FreeBSD Signed-off-by: Anton Tolchanov <anton@tailscale.com> (cherry picked from commit `9c2ad7086c`)	2 years ago
Mihai Parparita	78dec82736	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	613d624bea	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. This patch changes the WhoIs call to use the tsnet.Server LocalClient instead of the global tailscale LocalClient.

Tom DNetto	23a664325e	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).

Brad Fitzpatrick	b9e1c18578	net/netcheck: fix crash in checkCaptivePortal If netcheck happens before there's a derpmap. This seems to only affect Headscale because it doesn't send a derpmap as early? Change-Id: I51e0dfca8e40623e04702bc9cc471770ca20d2c2 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com> (cherry picked from commit `9a264dac01`)	2 years ago
James Tucker	a5340a07cf	wgengine/router: fix MTU configuration on Windows Always set the MTU to the Tailscale default MTU. In practice we are missing applying an MTU for IPv6 on Windows prior to this patch. This is the simplest patch to fix the problem, the code in here needs some more refactoring.

Mihai Parparita	a780929391	derp/derphttp: fix nil pointer dereference when closing a netcheck client NewNetcheckClient only initializes a subset of fields of derphttp.Client, and the Close() call added by #5707 was result in a nil pointer dereference. Make Close() safe to call when using NewNetcheckClient() too. Fixes #5919 Signed-off-by: Mihai Parparita <mihai@tailscale.com> (cherry picked from commit `b2855cfd86`)	2 years ago

Maisem Ali	f172fc42f7	ssh/tailssh: close sshContext on context cancellation This was preventing tailscaled from shutting down properly if there were active sessions in certain states (e.g. waiting in check mode). Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Hasnain Lakhani	8fe04b035c	tsweb: sort varz by name after stripping prefix (#5778 ) This makes it easier to view prometheus metrics. Added a test case which demonstrates the new behavior - the test initially failed as the output was ordered in the same order as the fields were declared in the struct (i.e. foo_a, bar_a, foo_b, bar_b). For that reason, I also had to change an existing test case to sort the fields in the new expected order. Signed-off-by: Hasnain Lakhani <m.hasnain.lakhani@gmail.com>	2 years ago

Brad Fitzpatrick	6d76764f37	ipn/ipnlocal: fix taildrop target list UI bug The macOS and iOS apps that used the /localapi/v0/file-targets handler were getting too many candidate targets. They wouldn't actually accept the file. This is effectively just a UI glitch in the wrong hosts being listed as valid targets from the source side.

Maisem Ali	b84ec521bf	ssh/tailssh: do not send EOT on session disconnection This was assumed to be the fix for mosh not working, however turns out all we really needed was the duplicate fd also introduced in the same commit (`af412e8874`).

Joe Tsai	82f5f438e0	wgengine/wgcfg: plumb down audit log IDs (#5855 ) The node and domain audit log IDs are provided in the map response, but are ultimately going to be used in wgengine since that's the layer that manages the tstun.Wrapper. Do the plumbing work to get this field passed down the stack. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Mihai Parparita	92ad56ddcb	cmd/tsconnect: close the SSH session an unload event instead of beforeunload The window may not end up getting unloaded (if other beforeunload handlers prevent the event), thus we should only close the SSH session if it's truly getting unloaded.

Joe Tsai	84e8f25c21	net/tstun: rename statististics method (#5852 ) Rename StatisticsEnable as SetStatisticsEnabled to be consistent with other similarly named methods. Rename StatisticsExtract as ExtractStatistics to follow the convention where methods start with a verb. It was originally named with Statistics as a prefix so that statistics related methods would sort well in godoc, but that property no longer holds.

Joe Tsai	3af0d4d0f2	logtail: always record timestamps in UTC (#5732 ) Upstream optimizations to the Go time package will make unmarshaling of time.Time 3-6x faster. See: * https://go.dev/cl/425116 * https://go.dev/cl/425197 * https://go.dev/cl/429862 The last optimization avoids a []byte -> string allocation if the timestamp string less than than 32B. Unfortunately, the presence of a timezone breaks that optimization. Drop recording of timezone as this is non-essential information. Most of the performance gains is upon unmarshal, but there is also a slight performance benefit to not marshaling the timezone as well.

Joe Tsai	c321363d2c	logtail: support a copy ID (#5851 ) The copy ID operates similar to a CC in email where a message is sent to both the primary ID and also the copy ID. A given log message is uploaded once, but the log server records it twice for each ID. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Joe Tsai	24ebf161e8	net/tstun: instrument Wrapper with statistics gathering (#5847 ) If Wrapper.StatisticsEnable is enabled, then per-connection counters are maintained.
