From 96fe84f42a361382b89f462873edae7c1236c303 Mon Sep 17 00:00:00 2001 From: Rebecca Troy Date: Fri, 17 Sep 2021 15:12:07 +0000 Subject: [PATCH] test/compress: fix buffer overflow Fixes stack buffer overflow bug in compressdev autotest, which was caused by the use of buf_idx in the debug logs. Originally, buf_idx was treated as an array instead of the reference of an integer. This was fixed by replacing the use of buf_idx[priv_data->orig_idx] with the variable i.
