Brad Fitzpatrick 2be07a36d6 wgengine/netstack: fix data race on shutdown (seen in TestTCPForwardLimits_PerClient) 
Wait for the inject func to be done when closing the netstack.Impl.

This sleep made it more flaky (racy) under flakestress for testing before & after:

    ns.packetsInFlight[tei] = struct{}{}
    ns.mu.Unlock()

    time.Sleep(10 * time.Millisecond)
    if debugNetstack() {
        ns.logf("[v2] netstack: in-flight connections for client %v: %d", remoteIP, inFlight)
    }

TestTCPForwardLimits_PerClient is no longer flaky.

Fixes #19720

router The connmark save/restore rules in mangle/PREROUTING restore the Tailscale bypass fwmark (0x80000) onto reply packets so that rp_filter's reverse-path check routes through the main table instead of table 52. However, the kernel only uses the packet's fwmark during the rp_filter lookup when net.ipv4.conf.all.src_valid_mark=1. (#19537) 2026-04-27 13:52:45 -04:00
