Summary
tls: Use __sk_dst_get() and dst_dev_rcu() in get_netdev_for_sock().
Details

In the Linux kernel, the following vulnerability has been resolved:

tls: Use _skdstget() and dstdevrcu() in getnetdevforsock().

getnetdevfor_sock() is called during setsockopt(), so not under RCU.

Using skdstget(sk)->dev could trigger UAF.

Let's use __skdstget() and dstdevrcu().

Note that the only ->ndoskgetlowerdev() user is bondskgetlowerdev(), which uses RCU.
