Hi Arnd, Russell, Linus,
Can we ensure the arm32 kprobes fix I submitted gets upstream before 5.0 final ? It takes care of an illegal instruction issue with optimized kprobes on arm32.
Here is the current state of default kprobes configuration on arm32: using them will trigger illegal instruction OOPS on v5.0-rc7, 4.19.24, v4.14.102.
My fix is in "accepted" state in the arm patch tracking system:
https://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=8834/1
Should I send it directly to Linus as well ?
Accepted means it's in my tree pending to be sent to Linus. It should now be in mainline. Have you checked?
Hrm, why did I not see it earlier today... it's embarrassing.
It's there indeed, all is good!
Greg, you should be able to pick it into the stable kernels now.
What is the git commit id of it?
Oh nevermind, I see it. I'll queue it up for the next round of kernel releases after this one.
Sorry about late reply, it's indeed commit 0ac569bf6a79 ("ARM: 8834/1: Fix: kprobes: optimized kprobes illegal instruction")
upstream.
Thanks!
Mathieu
