connmgr/tor.go: TorLookupIP

[Crypt-iQ]

It seems that buf only uses 6+len(host) bytes, but space is reserved for 7+len(host)?

Lines 79 to 86 in f86ae60

	buf = make([]byte, 7+len(host))
	buf[0] = 5 // protocol version
	buf[1] = '\xF0' // Tor Resolve
	buf[2] = 0 // reserved
	buf[3] = 3 // Tor Resolve
	buf[4] = byte(len(host))
	copy(buf[5:], host)
	buf[5+len(host)] = 0 // Port 0
