Subject: [PATCH 4.9 21/34] tipc: rate limit warning for received illegal binding update
Date: Mon, 14 Feb 2022 10:25:47 +0100	[thread overview]
Message-ID: <20220214092446.632050524@linuxfoundation.org> (raw)
In-Reply-To: <20220214092445.946718557@linuxfoundation.org>

From: Jon Maloy <jmaloy@redhat.com>

[ Upstream commit c7223d687758462826a20e9735305d55bb874c70 ]

It would be easy to craft a message containing an illegal binding table
update operation. This is handled correctly by the code, but the
corresponding warning printout is not rate limited as is should be.
We fix this now.
