From 0b857b44b5e445dc850cd91c45ce6edeb7797480 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Sun, 31 Jul 2016 00:27:39 -0700 Subject: [PATCH] nvme-rdma: Don't leak uninitialized memory in connect request private data Zero out the full nvme_rdma_cm_req structure before sending it. Otherwise we end up leaking kernel memory in the reserved field, which might break forward compatibility in the future.
