From e4514cbd972786af67dd6c442c072685387e22a2 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 27 May 2014 00:04:44 +0300 Subject: RDMA/cxgb3: Fix information leak in send_abort() The cpl_abort_req struct has several reserved members which need to be cleared to avoid disclosing kernel information. I have added a memset() so now it matches the cxgb4 version of this function.
