value FLEX_ARRAY_FREE (defined as 0x6c in <linux/poison.h>), so errors

What is hwpoison?
|
||||
|
||||
Upcoming Intel CPUs have support for recovering from some memory errors
|
||||
(``MCA recovery''). This requires the OS to declare a page "poisoned",
|
||||
kill the processes associated with it and avoid using it in the future.
|
||||
|
||||
This patchkit implements the necessary infrastructure in the VM.
|
||||
|
||||
To quote the overview comment:
|
||||
|
||||
* High level machine check handler. Handles pages reported by the
|
||||
* hardware as being corrupted usually due to a 2bit ECC memory or cache
|
||||
* failure.
|
||||
*
|
||||
* This focusses on pages detected as corrupted in the background.
|
||||
* When the current CPU tries to consume corruption the currently
|
||||
* running process can just be killed directly instead. This implies
|
||||
* that if the error cannot be handled for some reason it's safe to
|
||||
* just ignore it because no corruption has been consumed yet. Instead
|
||||
* when that happens another machine check will happen.
|
||||
*
|
||||
* Handles page cache pages in various states. The tricky part
|
||||
* here is that we can access any page asynchronous to other VM
|
||||
* users, because memory failures could happen anytime and anywhere,
|
||||
* possibly violating some of their assumptions. This is why this code
|
||||
* has to be extremely careful. Generally it tries to use normal locking
|
||||
* rules, as in get the standard locks, even if that means the
|
||||
* error handling takes potentially a long time.
|
||||
*
|
||||
* Some of the operations here are somewhat inefficient and have non
|
||||
* linear algorithmic complexity, because the data structures have not
|
||||
* been optimized for this case. This is in particular the case
|
||||
* for the mapping from a vma to a process. Since this case is expected
|
||||
* to be rare we hope we can get away with this.
|
||||
|
||||
The code consists of a the high level handler in mm/memory-failure.c,
|
||||
a new page poison bit and various checks in the VM to handle poisoned
|
||||
pages.
|
||||
|
||||
The main target right now is KVM guests, but it works for all kinds
|
||||
of applications. KVM support requires a recent qemu-kvm release.
|
||||
|
||||
For the KVM use there was need for a new signal type so that
|
||||
KVM can inject the machine check into the guest with the proper
|
||||
address. This in theory allows other applications to handle
|
||||
memory failures too. The expection is that near all applications
|
||||
won't do that, but some very specialized ones might.
|
||||
|
||||
---
|
||||
|
||||
There are two (actually three) modi memory failure recovery can be in:
|
||||
|
||||
vm.memory_failure_recovery sysctl set to zero:
|
||||
All memory failures cause a panic. Do not attempt recovery.
|
||||
(on x86 this can be also affected by the tolerant level of the
|
||||
MCE subsystem)
|
||||
|
||||
early kill
|
||||
(can be controlled globally and per process)
|
||||
Send SIGBUS to the application as soon as the error is detected
|
||||
This allows applications who can process memory errors in a gentle
|
||||
way (e.g. drop affected object)
|
||||
This is the mode used by KVM qemu.
|
||||
|
||||
late kill
|
||||
Send SIGBUS when the application runs into the corrupted page.
|
||||
This is best for memory error unaware applications and default
|
||||
Note some pages are always handled as late kill.

Limitations:
|

|
||||
- Not all page types are supported and never will. Most kernel internal
|

objects cannot be recovered, only LRU pages for now.
|
||||
- Right now hugepage support is missing.
