Subject: [PATCH 0/3] xfrm/compat: syzbot-found fixes

WARN_ON() for XFRMA_UNSPEC translation which likely no-one except
syzkaller uses; properly zerofy tail-padding for 64-bit attribute;
don't use __GFP_ZERO as the memory is initialized during translation.

Dmitry Safonov (3):
  xfrm/compat: Translate by copying XFRMA_UNSPEC attribute
  xfrm/compat: memset(0) 64-bit padding at right place
  xfrm/compat: Don't allocate memory with __GFP_ZERO
