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	39748e9562	net/dns/resolver: authoritatively return NXDOMAIN for reverse zones we own. Fixes #2774 Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	954064bdfe	wgengine/wgcfg/nmcfg: don't configure peers who can't DERP or disco. Fixes #2770 Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
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	dfd978f0f2	wgengine/magicsock: use NodeKey, not DiscoKey, as the trigger for lazy reconfig. 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. After the first netmap and DERP connect, then it transitions into "Running". Fixes #2708 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	7a7aa8f2b0	cmd/derper: also add port 80 timeouts Didn't notice this one in earlier `00b3c1c042` Updates tailscale/corp#2486 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
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. The earlier change `faa891c1f2` for #1905 was a bit too aggressive. Fixes #2757 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

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

Brad Fitzpatrick	73280595a8	derp: accept dup clients without closing prior's connection A public key should only have max one connection to a given DERP node (or really: one connection to a node in a region). But if people clone their machine keys (e.g. clone their VM, Raspbery Pi SD card, etc), then we can get into a situation where a public key is connected multiple times. Originally, the DERP server handled this by just kicking out a prior connections whenever a new one came. But this led to reconnect fights where 2+ nodes were in hard loops trying to reconnect and kicking out their peer. Then `a909d37a59` tried to add rate limiting to how often that dup-kicking can happen, but empirically it just doesn't work and ~leaks a bunch of goroutines and TCP connections, tying them up for hour+ while more and more accumulate and waste memory. Mostly because we were doing a time.Sleep forever while not reading from their TCP connections. Instead, just accept multiple connections per public key but track which is the most recent. And if two both are writing back & forth, then optionally disable them both. That last part is only enabled in tests for now. The current default policy is just last-sender-wins while we gather the next round of stats. Updates #2751 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
David Crawshaw	debaaebf3b	tstest/integration/vms: turn on logcatcher logging by default Absolutely vital to debugging failures. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	a1f1020042	tstest/integration/vms: avoid log after test completion Avoids a panic in the Go testing package if a late log comes in. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	583af7c1a6	tstest/integration/vms: give guest multiple cores and use generic machine Speeds up tests. Allows the use of more version of qemu. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	8668103f06	tstest/integration/vms: print qemu console output, fix printing issues Fix a few test printing issues when tests fail. Qemu console output is super useful when something is wrong in the harness and we cannot even bring up the tests. Also useful for figuring out where all the time goes in tests. A little noisy, but not too noisy as long as you're only running one VM as part of the tests, which is my plan. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	1a9fba5b04	tstest/integration/vms: fix ubuntu URLs Also remove extra distros for now. We can bring them back later if useful. Though our most important distros are these two Ubuntu, debian stable, and Raspbian (not currently supported). And before doing more Linux, we should do Windows.

Emmanuel T Odeke	0daa32943e	all: add (*testing.B).ReportAllocs() to every benchmark This ensures that we can properly track and catch allocation slippages that could otherwise have been missed. Fixes #2748	3 years ago
David Anderson	44d71d1e42	wgengine/magicsock: fix race in test shutdown, again. We were returning an error almost, but not quite like errConnClosed in a single codepath, which could still trip the panic on reconfig in the test logic. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	f09ede9243	wgengine/magicsock: don't configure eager WireGuard handshaking in tests. Our prod code doesn't eagerly handshake, because our disco layer enables on-demand handshaking. Configuring both peers to eagerly handshake leads to WireGuard handshake races that make TestTwoDevicePing flaky. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	86d1c4eceb	wgengine/magicsock: ignore close races even harder. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	8bacfe6a37	wgengine/magicsock: remove unused sendLogLimit limiter. Magicsock these days gets its logs limited by the global log limiter. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	e151b74f93	wgengine/magicsock: remove opts.SimulatedNetwork. It only existed to override one test-only behavior with a different test-only behavior, in both cases working around an annoying feature of our CI environments. Instead, handle that weirdness entirely in the test code, with a tweaked TestOnlyPacketListener that gets injected. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	58c1f7d51a	wgengine/magicsock: rename opts.PacketListener to TestOnlyPacketListener. The docstring said it was meant for use in tests, but it's specifically a special codepath that is _only_ used in tests, so make the claim stronger.

David Anderson	97693f2e42	wgengine/magicsock: delete legacy AddrSet endpoints. Instead of using the legacy codepath, teach discoEndpoint to handle peers that have a home DERP, but no disco key. We can still communicate with them, but only over DERP. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

Joe Tsai	3f1317e3e5	util/deephash: fix TestArrayAllocs Unfortunately this test fails on certain architectures. The problem comes down to inconsistencies in the Go escape analysis where specific variables are marked as escaping on certain architectures. The variables escaping to the heap are unfortunately in crypto/sha256, which makes it impossible to fixthis locally in deephash. For now, fix the test by compensating for the allocations that occur from calling sha256.digest.Sum. See golang/go#48055 Fixes #2727 Signed-off-by: Joe Tsai <joetsai@digital-static.net>	3 years ago
Joe Tsai	30458c71c8	tstime/rate: deflake TestLongRunningQPS This test is highly dependent on the accuracy of OS timers. Reduce the number of failures by decreasing the required accuracy from 0.999 to 0.995. Also, switch from repeated time.Sleep to using a time.Ticker for improved accuracy.
