		An AfterFilter represents a socket system call filter after an
		execution of a system call.
		
		It will only be executed after a system call for a socket that has
		an entry in internal table.
		If the filter returns a non-nil error, the system call function
		returns the non-nil error.


	
		A Filter represents a socket system call filter.
		
		It will only be executed before a system call for a socket that has
		an entry in internal table.
		If the filter returns a non-nil error, the execution of system call
		will be canceled and the system call function returns the non-nil
		error.
		It can return a non-nil [AfterFilter] for filtering after the
		execution of the system call.

		Sockets maps a socket descriptor to the status of socket.

		A Status represents the status of a socket.

		
			Cookie Cookie
			
				// error status of socket system call

			
				// error status of socket by SO_ERROR

		
			( Status) String() string
		
			 Status : expvar.Var

		A Switch represents a callpath point switch for socket system
		calls.

		
			
				Accept wraps syscall.Accept.

			
				Accept4 wraps syscall.Accept4.

			
				Close wraps syscall.Close.

			
				Connect wraps syscall.Connect.

			
				GetsockoptInt wraps syscall.GetsockoptInt.

			
				Listen wraps syscall.Listen.

			
				Set deploys the socket system call filter f for the filter type t.

			
				Socket wraps [syscall.Socket].

			
				Sockets returns mappings of socket descriptor to socket status.

			
				Stats returns a list of per-cookie socket statistics.
