I sent this forwarded msg to you only Lennart, its not in the archive. I was trying to be nice to you, yet you are as always, since you first joined this list, so very nasty to me. Read what you previously posted about how its the videos fault for starting near the end that you didnt understand what it was about. Thats a pretty lame thing to say. Its even lamer than pretending you get something you dont really get. Three posts in a row, your comments on this thread. Two of them responded to where I had sent private messages like the one below and you sent your reasoning to the list. Thats a particular kind of nasty that you exhibit towards me for whatever disfunctional reason that motivates you. I dont have to prove anything from the archives in order to show anyone else on the list just how disfunctional you are. You do it every time you say something stupid with the intent to show how smart you are. ---------- Forwarded message ---------- From: "Russell Reiter" <rreiter91@gmail.com> Date: Mar 13, 2017 10:50 AM Subject: Re: [GTALUG] DMA kernel attacks To: "Lennart Sorensen" <lsorense@csclub.uwaterloo.ca> Cc: On Mar 13, 2017 10:27 AM, "Lennart Sorensen" <lsorense@csclub.uwaterloo.ca> wrote: On Sat, Mar 11, 2017 at 01:02:45PM -0500, Russell Reiter via talk wrote:

Well first you have to install your PCIe card in the target machine, which means you would have to shut it down first, which could make booting it again difficult. Ummm ... PCIe is hot plugable with the right software. I thought initially they found a flaw in USB3, but no that is not the case. So it doesn't do anything we didn't already have a problem with in firewire years ago. So yes if you get to put your own PCIe hardware in a machine, you can DMA memory. And it's a bit faster than a firewire card was. The firewire and thunderbolt issues in the past seem much more of a concern than this because they were hardware already present in the target machine. This is pretty much just irrelevant. Maybe to you. I dont consider increase of transfer rate from 3mbs to 150mbs irrelevant by any means. Just because I highlight one bit of information which I gleaned from a source and wanted to share, as a matter of general interest; this doesent mean I didn't want you to learn from the post. I did it because I do want you to learn from it. Like you just now learned PCIe can be accessed without rebooting. -- Len Sorensen
