Kernel-memory-leaking Intel processor design flaw forces Linux, Windows redesign | Pe

I swear our HP Itanium servers at work are teflon dons. Just been dealing with Guard Bureau's inability to field a quality project team which they contracted out. The plan was to migrate HP U/X servers to Linux VMs along with Oracle database and WebLogic/Middleware on the application server side. Project keeps getting delayed because they underestimated Oracle's shadiness/pricing. Curious to see if this affects anything on top of it.

Itanium is unaffected.
 
Yeah, that's what I meant by teflon dons. Something always comes up where they show their worth time and time again even if they're ancient.
 
I had to deal with this today. It is a real pain in the ass and I have some insight for anyone that cares.

First - why did I have to deal with it? The mass patching has already begun and the cloud and ISP level. The patches are rolling. Therefore, it requires my attention.

Second - Do I think there will be any major impact? No. it is annoying as fuck. Especially since I feel like this is a well known exploit and there has been mass collusion to orchestrate the announcement and patches. The end result is going to be revenue for the hardware and software companies involved.

INTEL, AMD, NVIDIA, MICROSOFT, APPLE, LINUX/UNIX, ARM? Give me a fucking break. Look at that list again. What the fuck else is there?

So - remember the Apple battery slowdown debacle. I know - it was only in the last couple of weeks that they were caught red-handed building in a guaranteed upgrade due to battery age and purposeful throttling. This "patching" is liable to do just that - right under our noses. 5-30% performance hit? Gee - I wonder how many people will upgrade to "New, Harder Kernels with better performance!" Yeah - pretty much everyone. Stinks like shit.

Also, making the details public assures higher risk of attack vectors by knuckleheads. I am sure this is a well known vulnerability to folks like the NSA. What will they build into this "next generation?" Fuck this shit.

The entire thing smells like shit. People will start thinking about all that GPU based crypto processing going on right now and the chips in their hardware wallets etc and the crypto market could crash and burn off this too. Anyone think of that yet? Just wait.

Again - the entire thing smells like shit. I don't think there is really that big of a risk to machines operating inside private networks or running EPP etc. But - the patches will be forced. GG. Fuck everyone. Fuck you too. Stay off my fucking lawn.
 
Benchmarks don't seem to be showing any impact. About half of them seem slightly better if anything.

This is some other shit. Y'all being jade helmed
 
Yup.. heard an interview from one of the folks credited with uncovering it, who said that he noted before the exploit was announced, that AWS were using these patches that were deliberately costing them CPU cycles, and wondering why they'd be deliberately costing themselves more money like that, which is what got him looking at it.. So it's certainly been "known" by some for a while, even if not publicly announced.
 
For Google Chrome users

Here's how to turn on Site Isolation:

  • Copy chrome://flags/#enable-site-per-process and paste it into the URL field at the top of your Chrome web browser, and then hit the Enter key.
  • Look for Strict Site Isolation, then click the box labelled Enable.
  • Once done, hit Relaunch Now to relaunch your Chrome browser.
 
These patches may cause machines to slow down by up to 30 percent due to changes introduced to protect kernel memory. Initial speculation suggests this may increase the cost of cloud computing and that general end users should not notice performance degradation.

There we have it. Just when Adobe etc has basically forced everything onto a cloud based platform - here comes the price hike.
Even if there is absolutely no effect on performance, no one will ever be able to tell if there really was or not. Perfect excuse to hike the rates: 'Sorry, not our fault, blame intel, We had to buy faster hardware.'
 
Would this explain why it takes so fricken long to view the contents in another drive? I get sick and tired when i open file explorer, click on another drive and watch that green bar of death take its fricking time. REEEEEEEE!
 
I believe i just got the update. No sooner did i write the above post did M$ want my PC to reboot due to an update. :wet:
