Subject: [PATCH for-next 6/7] RDMA/rtrs: Do not allow sessname to contain special symbols / and .
Date: Wed, 22 Sep 2021 14:53:32 +0200 [thread overview]
Message-ID: <20210922125333.351454-7-haris.iqbal@ionos.com> (raw)
In-Reply-To: <20210922125333.351454-1-haris.iqbal@ionos.com>
Allowing these characters in sessname can lead to unexpected results,
particularly because / is used as a separator between files in a path,
and . points to the current directory.
