Subject: [PATCH libmlx5 1/6] fix size in malloc of qp->sq.wr_data
Date: Wed, 27 Jul 2016 15:17:22 -0400 [thread overview]
Message-ID: <1469647047-7544-2-git-send-email-jarod@redhat.com> (raw)
In-Reply-To: <1469647047-7544-1-git-send-email-jarod-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>
Coverity complaint:
1. libmlx5-1.2.1/src/verbs.c:989: suspicious_sizeof: Passing argument
"qp->sq.wqe_cnt * 8UL /* sizeof (qp->sq.wr_data) */" to function "malloc"
and then casting the return value to "uint32_t *" is suspicious.
2. libmlx5-1.2.1/src/verbs.c:989: remediation: Did you intend to use
"sizeof (*qp->sq.wr_data)" instead of "sizeof (qp->sq.wr_data)"?
# 987| }
# 988|
# 989|-> qp->sq.wr_data = malloc(qp->sq.wqe_cnt * sizeof(qp->sq.wr_data));
# 990| if (!qp->sq.wr_data) {
# 991| errno = ENOMEM;
The other mallocs in this same area properly use sizeof(*foo), this one
should too.
