Simon Law e4e59a2af0 wgengine/netstack: stop inject goroutine from leaking in Impl.Start (#19721) ... This patch fixes a data race in wgengine/netstack that surfaced while running both TestTCPForwardLimits and TestTCPForwardLimits_PerClient. Because these two tests both setup the TS_DEBUG_NETSTACK envknob, a race happens because netstack.Impl.Close leaked its inject goroutine. The inject goroutine also reads the TS_DEBUG_NETSTACK envknob, so if it is still running when the next test starts, then it will break. This patch also cleans up the tests a bit, ensuring that neither of them run in T.Parallel. It also adds a T.Cleanup call to clear the envknob.
