Subject: [PATCH 00/11] x86/ibt: FineIBT-BHI
Date: Fri, 07 Feb 2025 13:15:29 +0100 [thread overview]
Message-ID: <20250207121529.222723073@infradead.org> (raw)
Hi!
Respin of the FineIBT-BHI patches.
Scott has managed to get LLVM bits merged:
https://github.com/llvm/llvm-project/commit/e223485c9b38a5579991b8cebb6a200153eee245
Which prompted me to update these patches once again.
They boot and build the next kernel on my ADL when booted with: cfi=fineibt+bhi
Aside from the last two patches -- which implement the FineIBT-BHI scheme
proper -- I'm planning on getting these patches merged 'soon'.
Scott, what those last two patches need, aside from a lot more testing, is a
coherent writeup of how the mitigation works and ideally also a few numbers
proving the performance gains are worth it.
Last version at:
https://lore.kernel.org/all/20240927194856.096003183@infradead.org/T/#u
Current patches:
git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git x86/fineibt-bhi
Patches apply on top of tip/master.
