David Crawshaw	9502b515f1	net/dns: replace resolver IPs with type for DoH We currently plumb full URLs for DNS resolvers from the control server down to the client. But when we pass the values into the net/dns package, we throw away any URL that isn't a bare IP. This commit continues the plumbing, and gets the URL all the way to the built in forwarder. (It stops before plumbing URLs into the OS configurations that can handle them.) For #2596 Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
Brad Fitzpatrick	7bfd4f521d	cmd/tailscale: fix "tailscale ip $self-host-hostname" And in the process, fix the related confusing error messages from pinging your own IP or hostname. Fixes #2803 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	5a58fd8933	net/dnsfallback: go generate, pick up new DERPs Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
David Anderson	efe8020dfa	wgengine/magicsock: fix race condition in tests. AFAICT this was always present, the log read mid-execution was never safe. But it seems like the recent magicsock refactoring made the race much more likely. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Evan Anderson	000f90d4d7	wgengine/wglog: Fix docstring on wireguardGoString to match args @danderson linked this on Twitter and I noticed the mismatch. Signed-off-by: Evan Anderson <evan.k.anderson@gmail.com>	3 years ago

David Anderson	bb6fdfb243	net/dns: fix the build on freebsd (missing default case in switch) Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	b3b1c06b3a	net/dns: only restart systemd-resolved if we changed /etc/resolv.conf. Reported on IRC: in an edge case, you can end up with a directManager DNS manager and --accept-dns=false, in which case we should do nothing, but actually end up restarting resolved whenever the netmap changes, even though the user told us to not manage DNS. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	10547d989d	net/dns: exhaustively test DNS selection paths for linux. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	c071bcda33	net/dns: relax systemd-resolved detection. Reported on IRC: a resolv.conf that contained two entries for "nameserver 127.0.0.53", which defeated our "is resolved actually in charge" check. Relax that check to allow any number of nameservers, as long as they're all 127.0.0.53. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Dave Anderson	980acc38ba	types/key: add a special key with custom serialization for control private keys (#2792 ) * Revert "Revert "types/key: add MachinePrivate and MachinePublic."" This reverts commit `61c3b98a24`. Signed-off-by: David Anderson <danderson@tailscale.com> * types/key: add ControlPrivate, with custom serialization. ControlPrivate is just a MachinePrivate that serializes differently in JSON, to be compatible with how the Tailscale control plane historically serialized its private key. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	61c3b98a24	Revert "types/key: add MachinePrivate and MachinePublic." Broke the tailscale control plane due to surprise different serialization. This reverts commit `4fdb88efe1`.	3 years ago
David Anderson	4fdb88efe1	types/key: add MachinePrivate and MachinePublic. Plumb throughout the codebase as a replacement for the mixed use of tailcfg.MachineKey and wgkey.Private/Public. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

David Anderson	b96159e820	go.mod: update github.com/ulikunitz/xz for https://github.com/advisories/GHSA-25xm-hr59-7c27 Our code is not vulnerable to the issue in question: it only happens in the decompression path for untrusted inputs, and we only use xz as part of mkpkg, which is write-only and operates on trusted build system outputs to construct deb and rpm packages. Still, it's nice to keep the dependabot dashboard clean. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

Chuangbo Li	e4e4d336d9	cmd/derper: listen on host of flag server addr for port 80 and 3478 (#2768 ) cmd/derper: listen on host of flag server addr for port 80 and 3478 When using custom derp on the server with multiple IP addresses, we would like to bind derp 80, 443 and stun 3478 to a certain IP. derp command provides flag `-a` to customize which address to bind for port 443. But port :80 and :3478 were hard-coded. Fixes #2767 Signed-off-by: Li Chuangbo <im@chuangbo.li>	3 years ago
David Crawshaw	4e18cca62e	testcontrol: replace panic with error I have seen this once in the VM test (caused by an EOF, I believe on shutdown) that didn't need to cause the test to fail. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
Brad Fitzpatrick	5bacbf3744	wgengine/magicsock, health, ipn/ipnstate: track DERP-advertised health And add health check errors to ipnstate.Status (tailscale status --json). Updates #2746 Updates #2775 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	722942dd46	tsweb: restore CPU profiling handler It was accidentally deleted in the earlier `0022c3d2e` (#2143) refactor. Lock it in with a test. Fixes tailscale/corp#2503 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
David Anderson	daf54d1253	control/controlclient: remove TS_DEBUG_USE_DISCO=only. It was useful early in development when disco clients were the exception and tailscale logs were noisier than today, but now non-disco is the exception.

David Anderson	f90ac11bd8	wgengine: remove unnecessary magicConnStarted channel. Having removed magicconn.Start, there's no need to synchronize startup of other things to it any more. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	bb10443edf	wgengine/wgcfg: use just the hexlified node key as the WireGuard endpoint. The node key is all magicsock needs to find the endpoint that WireGuard needs. Updates #2752 Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

David Anderson	4c27e2fa22	wgengine/magicsock: remove Start method from Conn. Over time, other magicsock refactors have made Start effectively a no-op, except that some other functions choose to panic if called before Start. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

David Crawshaw	f53792026e	tstest/integration/vms: move build tags from linux to !windows The tests build fine on other Unix's, they just can't run there. But there is already a t.Skip by default, so `go test` ends up working fine elsewhere and checks the code compiles. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
Brad Fitzpatrick	7f29dcaac1	cmd/tailscale/cli: make up block until state Running, not just Starting At "Starting", the DERP connection isn't yet up.

Brad Fitzpatrick	3c8ca4b357	client/tailscale, cmd/tailscale/cli: move version mismatch check to CLI So people can use the package for whois checks etc without version skew errors.

Christine Dodrill	0b9e938152	tstest/integration/vms: test DNS configuration This uses a neat little tool to dump the output of DNS queries to standard out. This is the first end-to-end test of DNS that runs against actual linux systems. The /etc/resolv.conf test may look superflous, however this will help for correlating system state if one of the DNS tests fails. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
