This is a note to let you know that I've just added the patch titled tipc: rate limit warning for received illegal binding update to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: tipc-rate-limit-warning-for-received-illegal-binding.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit c850e26a471b13c2810566218a8e4abb6bd68b43 Author: Jon Maloy <jmaloy@xxxxxxxxxx> Date: Tue Feb 8 22:22:37 2022 -0500 tipc: rate limit warning for received illegal binding update [ 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.
