Subject: [ndctl PATCH 2/8] lib/libndctl: fix memory leakage problem in add_bus
Date: Fri, 6 Nov 2020 17:25:03 +0800	[thread overview]
Message-ID: <8caac123-9d45-c848-d45a-3cb8be5a2708@huawei.com> (raw)
In-Reply-To: <bed3b3b3-1f30-6751-c0bf-15ecf70192f9@huawei.com>


In add_bus(), bus->bus_path is set by calling parent_dev_path(),
which will finally adopt realpath(, NULL) to allocate new path.
However, bus->bus_path will not be freed in err_read tag, then,
memory leakage occurs.
