Subject: Re: [PATCH 1/2] lsm: Add hooks to the TUN driver

From: Paul Moore <paul.moore@...com>
Date: Fri, 28 Aug 2009 18:12:43 -0400

> The TUN driver lacks any LSM hooks which makes it difficult for LSM modules,
> such as SELinux, to enforce access controls on network traffic generated by
> TUN users; this is particularly problematic for virtualization apps such as
> QEMU and KVM.  This patch adds three new LSM hooks designed to control the
> creation and attachment of TUN devices, the hooks are:
> 
>  * security_tun_dev_create()
>    Provides access control for the creation of new TUN devices
> 
>  * security_tun_dev_post_create()
>    Provides the ability to create the necessary socket LSM state for newly
>    created TUN devices
> 
>  * security_tun_dev_attach()
>    Provides access control for attaching to existing, persistent TUN devices
>    and the ability to update the TUN device's socket LSM state as necessary
