Subject: [PATCH 0/3] xfrm/compat: syzbot-found fixes
Date: Fri, 30 Oct 2020 02:25:57 +0000 [thread overview]
Message-ID: <20201030022600.724932-1-dima@arista.com> (raw)
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.
