Subject: RE: [PATCH 2/3] x86/mce: Avoid infinite loop for copy from user recovery
Date: Fri, 30 Jul 2021 23:30:02 -0700 [thread overview]
Message-ID: <CAPcxDJ6qnrkuckxm6KkoONZZh5Q-H3-CkFiWq627p5OF3GKJ4Q@mail.gmail.com> (raw)
Been busy with some other work.
After cherry picking patch 1 & 2, I saw the following with 2 UC errors injected
into the user space buffer passed into write(2), as expected:
[ 287.994754] Kernel panic - not syncing: Machine checks to different
user pages
The kernel tested with has its x86/mce and mm/memory-failure aligned with
upstream till around 2020/11.
Is there any other patch that I have missed to the write syscall etc?
Thanks,
-Jue
