Subject: [PATCH] cifs: Use kzfree() to zero out the password
Date: Tue, 27 Aug 2019 10:59:17 +0000 [thread overview]
Message-ID: <20190827105917.GA23038@mwanda> (raw)
It's safer to zero out the password so that it can never be disclosed.
Fixes: 0c219f5799c7 ("cifs: set domainName when a domain-key is used in multiuser")
