xfrm_user: fix info leak in copy_to_user_auth()
[ Upstream commit 4c87308bdea31a7b4828a51f6156e6f721a1fcc9 ]
copy_to_user_auth() fails to initialize the remainder of alg_name and
therefore discloses up to 54 bytes of heap memory via netlink to
userland.
Use strncpy() instead of strcpy() to fill the trailing bytes of alg_name
with null bytes.
