selftests: rtnetlink: add addresses with fixed life time
[ Upstream commit 3cfa148826e3c666da1cc2a43fbe8689e2650636 ]
This exercises kernel code path that deal with addresses that have
a limited lifetime.
Without previous fix, this triggers following crash on net-next:
BUG: KASAN: null-ptr-deref in check_lifetime+0x403/0x670
Read of size 8 at addr 0000000000000010 by task kworker [..]
