Subject: [dpdk-dev] [PATCH v1 3/7] devargs: fix memory leak in legacy parser
Date: Fri,  8 Jan 2021 22:54:37 +0800
Message-ID: <20210108145441.23320-4-xuemingl@nvidia.com> (raw)
In-Reply-To: <1608304614-13908-2-git-send-email-xuemingl@nvidia.com>

Data field was designed as parser buffer, will be released once in
releasing struct memory. The duplicated device arguments was not saved
to data and this caused memory leak.

This patch fixes this leak by saving to new allocated memory to data
field.

Fixes: 4969f5914c9e ("devargs: introduce new parsing helper")
