I think that's what he said. He wasn't contradicting me, he was just

classic computer geek argument technique: when someone presents a
long-winded, obviously carefully thought-out argument you attack only
the minor points that you can pick apart and ignore the relevance of the
rest of the message.


I'm not sure what you mean.  I read that interview.  They're only
concentrating on one item, TLB.  That's all they talked about.  IIRC,
Theo never said TLB "will assuredly" be exploitable, he said some of
the bugs will be.

So, everyone picks up on the one thing that Linus fixed a while back,
the TLB stuff.  What about the rest of the bugs?  The non-TLB crap?
How is Art ignoring the relevance of the rest of the message?  He just
said, the TLB is just a minor issue, that the *OTHER* guys are
ignoring the major stuff.


the term "rathered" comes to mind.


I would go for "confused" and "not get the point".  Probably throw in
"didn't read the original article properly, and didn't visit the
referenced links" as well.

"rather" (except it is).

No he doesn't. The article is confused and missed the whole point.

The TLB issues are just one small part of what Theo was talking about,
not even the most important one.

Count the number of bugs in the errata. Only a very few of them deal with
the TLB and most of those are easy to deal with and we've already had
most of those right (the Core 2 problems we've been seeing are most
likely caused by a different errata that the operating system can't
do anything about, but I don't have any proof other than that updating
the BIOS helps). The biggest, potentially exploitable, issues are other
than the TLB issues.

I went and read the nice gif, there's actually another updated one
somewhere on the site.  If you looked at just the red ones, it's
scary.  There's even one with a math issue, there's one where the 2nd
core does not obey the NX bit, etc.  These are not TLB issues, and to
me, looks scary.
