    net: add socket system call hooks for testing · 29d1f3b8
    Mikio Hara authored
    This change adds socket system call hooks to existing test cases for
    simulating a bit complicated network conditions to help making timeout
    and dual IP stack test cases work more properly in followup changes.
    
    Also test cases print debugging information in non-short mode like the
    following:
    
    Leaked goroutines:
    net.TestWriteTimeout.func2(0xc20802a5a0, 0xc20801d000, 0x1000, 0x1000, 0xc2081d2ae0)
    	/go/src/net/timeout_test.go:170 +0x98
    created by net.TestWriteTimeout
    	/go/src/net/timeout_test.go:173 +0x745
    net.runDatagramPacketConnServer(0xc2080730e0, 0x2bd270, 0x3, 0x2c1770, 0xb, 0xc2081d2ba0, 0xc2081d2c00)
    	/go/src/net/server_test.go:398 +0x667
    created by net.TestTimeoutUDP
    	/go/src/net/timeout_test.go:247 +0xc9
    	(snip)
    
    Leaked sockets:
    3: {Cookie:615726511685632 Err:<nil> SocketErr:0}
    5: {Cookie:7934075906097152 Err:<nil> SocketErr:0}
