[Linux-stable-mirror] 4.9.62 breaks brcmfmac WiFi network scan

by Lambdadroid

Hi, I just upgraded from 4.9.61 to 4.9.63 and noticed that there are no longer any WiFi networks found after upgrading. After looking through the patches, it seems to be this brcmfmac commit from 4.9.62. Reverting it fixes the WiFi network scan. be5125d4fa9e: brcmfmac: setup wiphy bands after registering it first However, looking further at the patch, it seems like it was submitted together with another patch that wasn't applied to 4.9: 9ea0c307609f: brcmfmac: don't preset all channels as disabled Applying this patch additionally instead of reverting the broken patch seems to fix the issue as well. Either way works. I'm not sure why only one of the patches were applied to stable. They were submitted together on linux-wireless: http://www.spinics.net/lists/linux-wireless/msg157813.html For reference, I tested with a BCM43362 on Android and Arch Linux. Both didn't show any WiFi networks anymore after the update to 4.9.62+. Thanks!

The AMD severity grading function was introduced in kernel 4.1. The current logic can possibly give MCE_AR_SEVERITY for uncorrectable errors in kernel context. The system may then get stuck in a loop as memory_failure() will try to handle the bad kernel memory and find it busy. Return MCE_PANIC_SEVERITY for all UC errors IN_KERNEL context on AMD systems. After: b2f9d678e28c ("x86/mce: Check for faults tagged in EXTABLE_CLASS_FAULT exception table entries") was accepted in v4.6, this issue was masked because of the tail-end attempt at kernel mode recovery in the #MC handler.

[Linux-stable-mirror] Patch "x86/MCE/AMD: Always give panic severity for UC errors in kernel context" has been added to the 4.13-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled x86/MCE/AMD: Always give panic severity for UC errors in kernel context to the 4.13-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: x86-mce-amd-always-give-panic-severity-for-uc-errors-in-kernel-context.patch and it can be found in the queue-4.13 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From d65dfc81bb3894fdb68cbc74bbf5fb48d2354071 Mon Sep 17 00:00:00 2001 From: Yazen Ghannam <yazen.ghannam(a)amd.com> Date: Mon, 6 Nov 2017 18:46:32 +0100 Subject: x86/MCE/AMD: Always give panic severity for UC errors in kernel context From: Yazen Ghannam <yazen.ghannam(a)amd.com> commit d65dfc81bb3894fdb68cbc74bbf5fb48d2354071 upstream. The AMD severity grading function was introduced in kernel 4.1. The current logic can possibly give MCE_AR_SEVERITY for uncorrectable errors in kernel context. The system may then get stuck in a loop as memory_failure() will try to handle the bad kernel memory and find it busy. Return MCE_PANIC_SEVERITY for all UC errors IN_KERNEL context on AMD systems. After: b2f9d678e28c ("x86/mce: Check for faults tagged in EXTABLE_CLASS_FAULT exception table entries") was accepted in v4.6, this issue was masked because of the tail-end attempt at kernel mode recovery in the #MC handler. However, uncorrectable errors IN_KERNEL context should always be considered unrecoverable and cause a panic.
