Fixes copying of xfrm algorithms where some random data of the structure fields can end up in userspace. Padding in structures may be filled with random (possibly sensitve) data and should never be given directly to user-space.
A similar issue was resolved in the commit 8222d5910dae ("xfrm: Zero padding when dumping algos and encap")
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
