Описание
In the Linux kernel, the following vulnerability has been resolved:
nvmet: always initialize cqe.result
The spec doesn't mandate that the first two double words (aka results) for the command queue entry need to be set to 0 when they are not used (not specified). Though, the target implemention returns 0 for TCP and FC but not for RDMA.
Let's make RDMA behave the same and thus explicitly initializing the result field. This prevents leaking any data from the stack.
