Summary

ipv6: ioam: fix potential NULL dereferences in __ioam6_fill_trace_data()

Details

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

ipv6: ioam: fix potential NULL dereferences in _ioam6filltracedata()

We need to check __in6devget() for possible NULL value, as suggested by Yiming Qian.

Also add skbdstdevrcu() instead of skbdstdev(), and two missing READONCE().

Note that @dev can't be NULL.
