Linux Kernel Patched For Branch History Injection "BHI" Intel CPU Vulnerability

[pWe00Iri3e7Z9lHOX2Qx]

To address this question, we developed InSpectre Gadget

Okay, that name is gold.

The good thing about the chip war is that we might see cheaper, better and more secure Chinese CPUs in the future.

That American and Israeli bullshit full of backdoors and vulnerabilities is already getting old. The whole world is waiting for a replacement.
This alone makes me already support Xi Jinping.

<Jia Tan has entered the chat>

Did somebody say backdoors?

I also like how even this many years later nobody is even planning on maybe fixing the hardware. "lets just keep making new shit the same way and here maybe you can have a microcode update once in a while and some lunix patches to slow your computer down by 5000% thats good enough right?"

just how many years do you think it takes to design a new part of a CPU?

I know that newer CPUs do not have some of the old vulns, so there is progress on that front.

but hey, I'd rather have parts that go fast and get mitigations than going back to the old days of in-order CPU execution

Let's just hope it happens before we all be abducted by space aliens.

at least they will not judge you because of watching porn. they know that we are just intelligent monkeys. Not more not less.

Then I guess you're fine with Chinese CPU's having their own backdoor spyware so that Xi Jinping can see what type of p*rn you watch..

But hey, +500 social credit points to you. You must be very hungry for those sweet sweet social credit points.

Yes, i am fine with that one.
Since i am not living in China, it doesn't affect me at all whether or not Xi Jinping knows that i am listening to KPOP.
Meanwhile if Western glowies know that i said a no-no-word once, they can destroy my life, lock my bank accounts, force my employer to fire me and even throw me into jail for multiple years before getting a trial.

Maybe I missed the irony here, but I would not expect Chinese chips to be any better. All sorts of gouvernments do not trust their own people, thus, they want backdoors.
An open and free(dom) design would be nice for a change.
And one should not forget that weaknesses or even intentional backdoors can be implemented on many levels/layers of a computer.

IntelLeak comes again. Too much money, too much hardware bugs and vulnerabilities.

Silicon Slip, Intel Leak, MBA Meltdown.

Welcome to Intel mafia!

Because... this mess is unfixable? Once you give up on speed hacks the CPU will not be as fast as before. Cheating is not a flaw, it is a strategy which always fire back, indirectly. All these Vulnerabilities are not errors and have never been, it's the cheats uncovered. Both Intel and AMD has become cheat addicts and proficient at cheating but cheating in essence is not fixable, the "solutions" just stack up more cheat on cheats and on and on.

Until the approach changes there is nothing to fix.

so whats the impact on performance with this patch

[Weasel]

mitigations=off i915.mitigations=off

Even better, if you build your own kernel:

CONFIG_SPECULATION_MITIGATIONS=n

Turn it off via command line still adds some overhead unfortunately. To truly get rid of it you need to build it with that.
