Message-ID: <1440147411-129581-1-git-send-email-long.wanglong@huawei.com> Date: Fri, 21 Aug 2015 08:56:51 +0000 From: Wang Long <long.wanglong@...wei.com> To: <a.ryabinin@...sung.com>, <ryabinin.a.a@...il.com> CC: <akpm@...ux-foundation.org>, <adech.fo@...il.com>, <linux-kernel@...r.kernel.org>, <wanglong@...qinren.net>, <peifeiyue@...wei.com>, <long.wanglong@...wei.com> Subject: [RFC PATCH] test_kasan: make kmalloc_oob_krealloc_less more correctly In kmalloc_oob_krealloc_less, I think it is better to test the size2 boundary. If we do not call krealloc, the access of position size1 will still cause out-of-bounds and access of position size2 does not. After call krealloc, the access of position size2 cause out-of-bounds. So, use size2 is more correctly.
