3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Borkmann <dborkman@xxxxxxxxxx>
[ Upstream commit 446266b0c742a2c9ee8f0dce759a0117bce58a86 ]
Commit 5c766d642 ("ipv4: introduce address lifetime") leaves the ifa
resource that was allocated via inet_alloc_ifa() unfreed when returning
the function with -EINVAL. Thus, free it first via inet_free_ifa().
