Pierre Souchay	5703aadb59	[BUGFIX] Fix race condition in freeport (#7567 ) This removes a race condition in reset since pendingPorts can be set to nil in reset() If ticker is hit at wrong time, it would crash the unit test. We ensure in reset to avoid this race condition by cancelling the goroutine using killTicker chan. We also properly clean up eveything, so garbage collector can work as expected. To reproduce existing bug: `while go test -timeout 30s github.com/hashicorp/consul/sdk/freeport -run '^(Test.)$'; do go clean -testcache; done` Will crash after a few 10s runs on my machine. Error could be seen in unit tests sometimes: [INFO] freeport: resetting the freeport package state panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x28 pc=0x1125536] goroutine 25 [running]: container/list.(List).Len(...) /usr/local/Cellar/go/1.14/libexec/src/container/list/list.go:66 github.com/hashicorp/consul/sdk/freeport.checkFreedPortsOnce() /Users/p.souchay/go/src/github.com/hashicorp/consul/sdk/freeport/freeport.go:157 +0x86 github.com/hashicorp/consul/sdk/freeport.checkFreedPorts() /Users/p.souchay/go/src/github.com/hashicorp/consul/sdk/freeport/freeport.go:147 +0x71 created by github.com/hashicorp/consul/sdk/freeport.initialize /Users/p.souchay/go/src/github.com/hashicorp/consul/sdk/freeport/freeport.go:113 +0x2cf FAIL github.com/hashicorp/consul/sdk/freeport 1.607s	5 years ago
Pierre Souchay	952b60abaa	Proper detection of ephemeral ports on Mac OS (#7539 ) Use systemctl to properly detect ephemeral ports on Mac OS (aka darwin) by fetching systemctl values: * net.inet.ip.portrange.first * net.inet.ip.portrange.last This will avoid the message: `[INFO] freeport: ephemeral port range detection not configured for GOOS="darwin"` and properly detect the correct port range	5 years ago
Hans Hasselberg	804eb17094	connect: check if intermediate cert needs to be renewed. (#6835 ) Currently when using the built-in CA provider for Connect, root certificates are valid for 10 years, however secondary DCs get intermediates that are valid for only 1 year. There is no mechanism currently short of rotating the root in the primary that will cause the secondary DCs to renew their intermediates. This PR adds a check that renews the cert if it is half way through its validity period. In order to be able to test these changes, a new configuration option was added: IntermediateCertTTL which is set extremely low in the tests.	5 years ago

R.B. Boyer	f9496dc627	sdk: add freelist tracking and ephemeral port range skipping to freeport This should cut down on test flakiness. Problems handled: - If you had enough parallel test cases running, the former circular approach to handling the port block could hand out the same port to multiple cases before they each had a chance to bind them, leading to one of the two tests to fail. - The freeport library would allocate out of the ephemeral port range. This has been corrected for Linux (which should cover CI). - The library now waits until a formerly-in-use port is verified to be free before putting it back into circulation.	5 years ago
