Brad Fitzpatrick	7901289578	wgengine/magicsock: add a stress test And add a peerMap validate method that checks its internal invariants. Updates tailscale/corp#3016 Change-Id: I23708e68ed44d81986d9e2be82029d4555547592 Co-authored-by: Brad Fitzpatrick <bradfitz@tailscale.com> Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	5a60781919	wgengine/magicsock: increase TestDiscokeyChange connection timeout I believe that this should eliminate the flakiness. If GitHub CI manages to be even slower that can be believed (and I can believe a lot at this point), then we should roll this back and make some more invasive changes. Updates #654 Fixes #3247 (I hope) Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	9da22dac3d	wgengine/magicsock: fix bug in peerMap.upsertEndpoint Found by inspection by David Crawshaw while investigating tailscale/corp#3016. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
David Anderson	41da7620af	go.mod: update wireguard-go to pick up roaming toggle wgengine/wgcfg: introduce wgcfg.NewDevice helper to disable roaming at all call sites (one real plus several tests).

Josh Bleecher Snyder	94fb42d4b2	all: use testingutil.MinAllocsPerRun There are a few remaining uses of testing.AllocsPerRun: Two in which we only log the number of allocations, and one in which dynamically calculate the allocations target based on a different AllocsPerRun run. This also allows us to tighten the "no allocs" test in wgengine/filter. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	1df865a580	wgengine/magicsock: allow even fewer allocs per UDP receive We improved things again for Go 1.18. Lock that in. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	c1d377078d	wgengine/magicsock: use testingutil.MinAllocsPerRun This speeds up and deflakes the test. Fixes #2826 (again) Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

David Crawshaw	3552d86525	wgengine/magicsock: turn down timeouts in tests Before: --- PASS: TestActiveDiscovery (11.78s) --- PASS: TestActiveDiscovery/facing_easy_firewalls (5.89s) --- PASS: TestActiveDiscovery/facing_nats (5.89s) --- PASS: TestActiveDiscovery/simple_internet (0.89s) After: --- PASS: TestActiveDiscovery (1.98s) --- PASS: TestActiveDiscovery/facing_easy_firewalls (0.99s) --- PASS: TestActiveDiscovery/facing_nats (0.99s) --- PASS: TestActiveDiscovery/simple_internet (0.89s) Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Anderson	b956139b0c	wgengine/magicsock: track IP<>node mappings without relying on discokeys. Updates #3088. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Brad Fitzpatrick	569f70abfd	wgengine/magicsock: finish some renamings of discoEndpoint to endpoint Renames only; continuation of earlier `8049063d35` These kept confusing me while working on #3088 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	d86081f353	wgengine/magicsock: add new discoInfo type for DiscoKey state, move some fields As more prep for removing the false assumption that you're able to map from DiscoKey to a single peer, move the lastPingFrom and lastPingTime fields from the endpoint type to a new discoInfo type, effectively upgrading the old sharedDiscoKey map (which only held a *[32]byte nacl precomputed key as its value) to discoInfo which then includes that naclbox key. Then start plumbing it into handlePing in prep for removing the need for handlePing to take an endpoint parameter. Updates #3088 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	3e80806804	wgengine/magicsock: pass src NodeKey to handleDiscoMessage for DERP disco msgs And then use it to avoid another lookup-by-DiscoKey. Updates #3088	3 years ago
David Anderson	830f641c6b	wgengine/magicsock: update discokeys on netmap change. Fixes #3008. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Josh Bleecher Snyder	a722e48cef	wgengine/magicsock: skip alloc test with -race Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Brad Fitzpatrick	31c1331415	wgengine/magicsock: deflake TestReceiveFromAllocs 100 iterations isn't enough with background allocs happening apparently. 1000 seems to be reliable. Fixes #2826 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	640134421e	all: update tests to use tstest.MemLogger And give MemLogger a mutex, as one caller had, which does match the logf contract better. 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
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 Anderson	1a899344bd	wgengine/magicsock: don't store tailcfg.Nodes alongside endpoints. Updates #2752 Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
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	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	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. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	8049063d35	wgengine/magicsock: rename discoEndpoint to just endpoint. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	fe2f89deab	wgengine/magicsock: fix rare shutdown race in test. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
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
Josh Bleecher Snyder	8a3d52e882	wgengine/magicsock: use mono.Time magicsock makes multiple calls to Now per packet. Move to mono.Now. Changing some of the calls to use package mono has a cascading effect, causing non-per-packet call sites to also switch. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	4f4dae32dd	wgengine/magicsock: fix latent data race in test logBufWriter had no serialization. It just so happens that none of its users currently ever log concurrently. Make it safe for concurrent use. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Brad Fitzpatrick	7e7c4c1bbe	tailcfg: break DERPNode.DERPTestPort into DERPPort & InsecureForTests The DERPTestPort int meant two things before: which port to use, and whether to disable TLS verification. Users would like to set the port without disabling TLS, so break it into two options. Updates #1264 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
julianknodt	506c2fe8e2	cmd/tailscale: make netcheck use active DERP map, delete static copy After allowing for custom DERP maps, it's convenient to be able to see their latency in netcheck. This adds a query to the local tailscaled for the current DERPMap. Updates #1264 Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago
Josh Bleecher Snyder	1ece91cede	go.mod: upgrade wireguard-windows, de-fork wireguard-go Pull in the latest version of wireguard-windows. Switch to upstream wireguard-go. This requires reverting all of our import paths. Unfortunately, this has to happen at the same time. The wireguard-go change is very low risk, as that commit matches our fork almost exactly. (The only changes are import paths, CI files, and a go.mod entry.) So if there are issues as a result of this commit, the first place to look is wireguard-windows changes.

Josh Bleecher Snyder	25df067dd0	all: adapt to opaque netaddr types This commit is a mishmash of automated edits using gofmt: gofmt -r 'netaddr.IPPort{IP: a, Port: b} -> netaddr.IPPortFrom(a, b)' -w . gofmt -r 'netaddr.IPPrefix{IP: a, Port: b} -> netaddr.IPPrefixFrom(a, b)' -w . gofmt -r 'a.IP.Is4 -> a.IP().Is4' -w . gofmt -r 'a.IP.As16 -> a.IP().As16' -w . gofmt -r 'a.IP.Is6 -> a.IP().Is6' -w . gofmt -r 'a.IP.As4 -> a.IP().As4' -w . gofmt -r 'a.IP.String -> a.IP().String' -w . And regexps: \w(.)\.Port = (.) -> $1 = $1.WithPort($2) \w(.)\.IP = (.) -> $1 = $1.WithIP($2) And lots of manual fixups. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
