Subject: Re: [PATCH] KERNEL: resource: Fix bug on leakage in /proc/iomem file
Date: Wed, 06 Apr 2016 13:05:56 -0500	[thread overview]
Message-ID: <5e5e7c7ced7bede343530ed1447d7453@abdsec.com> (raw)
In-Reply-To: <CA+55aFykp_ifLG=GkdGEM2keZs1Kb=eYcjjLz1LQh78LVSZong@mail.gmail.com>

First, I wrote your attached patch, but then I thought zeroing other 
/proc/iomem values would be better. So I changed it.

Most distros don't use KASLR, but they use kptr_restrict. Without KASLR, 
kptr_restirct most likely useless. As you said these things should be 
done long ago
