Analyze and fix the following issue in the Linux kernel code: [IPV6]: Fix the return value of get destination options with NULL data pointer
Problem Details: If we pass NULL data buffer to getsockopt(), it will return 0, and the option length is set to -EFAULT: getsockopt(sk, IPPROTO_IPV6, IPV6_DSTOPTS, NULL, &len); This is because ipv6_getsockopt_sticky() will return -EFAULT or -EINVAL if some error occur.
