Christine Dodrill	81466eef81	Add an environment variable to enable customizing the log target (#1243 ) Signed-off-by: Christine Dodrill <xe@tailscale.com>	4 years ago
David Anderson	45fe06a89f	Revert "tailcfg: remove v6-overlay debug option." This reverts commit `da4ec54756`. Since v6 got disabled for Windows nodes, I need the debug flag back to figure out why it was broken. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Josh Bleecher Snyder	e8cd7bb66f	tstest: simplify goroutine leak tests Use tb.Cleanup to simplify both the API and the implementation. One behavior change: When the number of goroutines shrinks, don't log. I've never found these logs to be useful, and they frequently add noise.

Brad Fitzpatrick	9a70789853	cmd/tailscale: fix IPN message reading stall in tailscale status -web Fixes #1234 Updates #1254	4 years ago
Brad Fitzpatrick	a2aa6cd2ed	wgengine/router: clarify disabled IPv6 message on Linux	4 years ago
David Crawshaw	d139fa9c92	net/interfaces: use a uint32_t for ipv4 address The code was using a C "int", which is a signed 32-bit integer. That means some valid IP addresses were negative numbers. (In particular, the default router address handed out by AT&T fiber: 192.168.1.254. No I don't know why they do that.) A negative number is < 255, and so was treated by the Go code as an error. This fixes the unit test failure: $ go test -v -run=TestLikelyHomeRouterIPSyscallExec ./net/interfaces === RUN TestLikelyHomeRouterIPSyscallExec interfaces_darwin_cgo_test.go:15: syscall() = invalid IP, false, netstat = 192.168.1.254, true --- FAIL: TestLikelyHomeRouterIPSyscallExec (0.00s) Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	4 years ago
David Anderson	267531e4f8	wgengine/router: probe better for v6 policy routing support. Previously we disabled v6 support if the disable_policy knob was missing in /proc, but some kernels support policy routing without exposing the toggle. So instead, treat disable_policy absence as a "maybe", and make the direct `ip -6 rule` probing a bit more elaborate to compensate. Fixes #1241.

Brad Fitzpatrick	006a224f50	ipn/ipnserver, cmd/hello: do whois over unix socket, not debug http Start of a local HTTP API. Not a stable interface yet.	4 years ago
Josh Bleecher Snyder	fe7c3e9c17	all: move wgcfg from wireguard-go This is mostly code movement from the wireguard-go repo. Most of the new wgcfg package corresponds to the wireguard-go wgcfg package. wgengine/wgcfg/device{_test}.go was device/config{_test}.go. There were substantive but simple changes to device_test.go to remove internal package device references. The API of device.Config (now wgcfg.DeviceConfig) grew an error return; we previously logged the error and threw it away. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

Josh Bleecher Snyder	1e28207a15	types/logger: fix rateFree interaction with verbosity prefixes We log lines like this: c.logf("[v1] magicsock: disco: %v->%v (%v, %v) sent %v", c.discoShort, dstDisco.ShortString(), dstKey.ShortString(), derpStr(dst.String()), disco.MessageSummary(m)) The leading [v1] causes it to get unintentionally rate limited. Until we have a proper fix, work around it. Fixes #1216 Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

Brad Fitzpatrick	9f5b0d058f	wgengine: fix bugs from earlier fix Fixes a regression from `e970ed0995` that wasn't covered by tests in this repo. (Our end-to-end tests in another repo caught this.) Updates #1204	4 years ago

Brad Fitzpatrick	4fea604979	wgengine/router: stop setPrivateNetwork goroutine on configureInterface failure On Windows, configureInterface starts a goroutine reconfiguring the Windows firewall. But if configureInterface fails later, that goroutine kept running and likely failing forever, spamming logs. Make it stop quietly if its launching goroutine filed.	4 years ago
Andrey Petrov	bf6205d200	LICENSE: Reformat for Github Should be equivalent to the license before, but compatible with the library Github uses to detect the license for the project's metadata: https://docs.github.com/en/github/creating-cloning-and-archiving-repositories/licensing-a-repository#detecting-a-license Signed-off-by: Andrey Petrov <andrey.petrov@shazow.net>	4 years ago

Brad Fitzpatrick	97496a83af	wgengine/tstun: also support DropSilently on PostFilterIn Not a problem (yet). But should be consistent with other places that support both types of drops.	4 years ago

Josh Bleecher Snyder	d5baeeed5c	wgengine: use Tailscale-style peer identifiers in logs Rewrite log lines on the fly, based on the set of known peers. This enables us to use upstream wireguard-go logging, but maintain the Tailscale-style peer public key identifiers that the rest of our systems (and people) expect. Fixes #1183 Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Brad Fitzpatrick	4306433d1c	cmd/tailscale: make "tailscale ping" also resolve names without DNS This lets "tailscale ping $NAME" work even if MagicDNS is off, letting you ping a name that shows up in "tailscale status". More user friendly.	4 years ago

Brad Fitzpatrick	54d0d83b67	safesocket: on Linux, make /var/run/tailscale be 0755 Continuation of earlier two umask changes, `5611f290eb` and `d6e9fb1df0`. This change mostly affects us, running tailscaled as root by hand (wit a umask of 0077), not under systemd. End users running tailscaled under systemd won't have a umask.
