Josh Bleecher Snyder	3ea8cf9c62	ipn/ipnlocal: use quicktest.IsNotNil in tests This didn't exist when the test was written. Now it does (frankban/quicktest#94); use it. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Josh Bleecher Snyder	b681edc572	ipn/ipnlocal: add failing test Concurrent calls to LocalBackend.setWgengineStatus could result in some of the status updates being dropped. This was exacerbated by `92077ae78c`, which increases the probability of concurrent status updates, causing test failures (tailscale/corp#2579). It's going to take a bit of work to fix this test. The ipnlocal state machine is difficult to reason about, particularly in the face of concurrency. We could fix the test trivially by throwing a new mutex around setWgengineStatus to serialize calls to it, but I'd like to at least try to do better than cosmetics. In the meantime, commit the test.

Josh Bleecher Snyder	7693d36aed	all: close fake userspace engines when tests complete We were leaking FDs. In a few places, switch from defer to t.Cleanup. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	008f36986e	.github/workflows: remove separate "build stringer" step We now use "go run" instead of compiling stringer separately. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	9faee90744	.github/workflows: skip net/dnsfallback go generate check on release branch We don't want to force ourselves to update the DERP list every time we want to cut a new release. Having an outdated DERP list on release branches is OK. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	4bbf5a8636	cmd/cloner: reduce diff noise when changing command Spelling out the command to run for every type means that changing the command makes for a large, repetitive diff. Stop doing that. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	865d8c0d23	cmd: upgrade to ffcli v3 None of the breaking changes from v2 to v3 are relevant to us. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	a3c5de641b	portlist: stop logging stray UDP ports These "weird" port lines show up in logs frequently. They're the result of uninteresting races, and they're not actionable. Remove the noise. Remove the isLoopbackAddr case to placate staticcheck. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Josh Bleecher Snyder	3759fb8987	derp: deflake TestSendFreeze On about 1 out of 500 runs, TestSendFreeze failed: derp_test.go:416: bob: unexpected message type derp.PeerGoneMessage Closing alice before bob created a race. If bob closed promptly, the test passed. If bob closed slowly, and alice's disappearance caused bob to receive a PeerGoneMessage before closing, the test failed. Deflake the test by closing bob first. With this fix, the test passed 12,000 times locally. Fixes #2668 Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Brad Fitzpatrick	0be26599ca	cmd/derper: refactor STUN path for testing, add serverSTUN benchmark Real goal is to eliminate some allocs in the STUN path, but that requires work in the standard library. See comments in #2783. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	64e9ce8df1	portlist: reduce allocs on Linux Notably, it no longer allocates proportional to the number of open sockets on the machine.

Brad Fitzpatrick	a353fbd3b4	tstest: make MemLogger.String acquire its mutex Updates #2781 (might even fix it, but its real issue is that SetPrivateKey starts a ReSTUN goroutines which then logs, and that bug and data race existed prior to MemLogger existing)	3 years ago

Silver Bullet	d8c5d00ecb	cmd/derper: support manual TLS certificate mode (#2793 ) Add a mode control for derp server, and add a "manual" mode to get derp server certificate. Under manual mode, certificate is searched in the directory given by "--cert-dir". Certificate should in PEM format, and use "hostname.{key,crt}" as filename. If no hostname is used, search by the hostname given for listen. Fixes #2794 Signed-off-by: SilverBut <SilverBut@users.noreply.github.com>	3 years ago

Brad Fitzpatrick	2bb0eb5f7e	ipn/ipnlocal: pull out dns.Config construction to its own func In prep for other bug fixes & tests. It's hard to test when it was intermingled into LocalBackend.authReconfig. Now it's a pure function. And rename variable 'uc' (user config?) to the since idiomatic 'prefs'.

David Crawshaw	b2a3d1da13	tstest/integration/vms: use fork of goexpect to avoid proto/grpc dep Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
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
