CVE-2018-12207: Intel Processor Machine Check Error Advisory

CVE-2019-11135: Intel TSX Asynchronous Abort (TAA)

Affected Windriver Linux releases:

All releases including Wind River Linux LTS 19, Wind River Linux LTS 18, Wind River Linux LTS 17, Wind River Linux 9, Wind River Linux 8, Wind River Linux 7

Affected software components:

Linux kernel.

Affected hardware:

Almost all Intel CPUs, different CVE issues related to different CPU, for details, plese refer to related webpag: CVE-2019-11135, CVE-2019-11139, CVE-2019-0154, CVE-2019-0155.

Intel Ethernet 700 Series Controller.

Mitigation

For CPU related issue, upgrade CPU microcode once available.

For NIC controller issue, use newest driver and upgrade the newest firmware.

Note:

• For these two CVEs related to Intel CPU, if your CPU not been listed in these two web pages, please just ignore them: CVE-2019-11135, CVE-2019-11139
• For the microcode upgrading, to make a full mitigation, the new microcode should be upgraded through BIOS. So please contact your BIOS vendor for it.
• For these NIC related CVEs, they only effect on Intel Ethernet 700 Series Controller, in linux it called "i40e", if you have no such NIC device, just ignore them.

Installation Notes

Steps to build NIC driver : i40e

For all supported releases except WRL8:

1) Download the newest driver package from Intel:

https://downloadmirror.intel.com/22283/eng/24_3.zip

There are some older versions like 24_2, 24.1 may also fixed those CVEs but now, we only tried v-24.3, the newest version. The version of i40e in 24.3 is 2.10.19.

2) Get the source code from 24_3.zip:

$ mkdir /PATCH_1

$ cp 24_3.zip /PATCH_1

$ cd /PATCH_1

$ md5sum 24_3.zip

1b9acacdcb57c3777e63865f2fadc844 24_3.zip

...

$ md5sum PRO40GB/Linux/i40e-2.10.19.30.tar.gz

9af74c805302b85ed92b68fd41b18e3e PRO40GB/Linux/i40e-2.10.19.30.tar.gz

$ cd /PATCH_2_WRL_PROJ

$ . oe-init-build-env

# suppose your kernel is linux-yocto.

$ bitbake linux-yocto -c devshell

BTW: For WRL9 and earlier release, the command line should be:

$ make bbs

$ bitbake linux-windriver -c devshell

4) Build I40E driver

$ make menuconfig

Set CONFIG_I40E=n manually.

$ make CONFIG_I40E=m M=/PATH_2_BUILD_DRIVER/i40e-2.10.19.30/src modules

Now you get the kene module /PATH_2_BUILD_DRIVER/i40e-2.10.19.30/src/i40e.ko .

Steps to upgrade firmware for Intel Ethernet 700 Series Controller

The package fits for Linux, Windows and some other OS environment

1) Download the newest Non-Volatile Memory (NVM) Update Utility package from Intel:

https://downloadcenter.intel.com/download/24769/Non-Volatile-Memory-NVM-Update-Utility-for-Intel-Ethernet-Network-Adapter-700-Series

In this web page, you can get the newest package: NVMUpdatePackage_700_Series.zip

This package can be used to upgrade the firmware on Linux, Windows, EFI, VMware ESX and FreeBDS.

$ md5sum NVMUpdatePackage_700_Series.zip

26800f13868e8838df9aad4a26d34c71 NVMUpdatePackage_700_Series.zip

2) Unpackage it and choose the one fit for you, for Linux:

$ unzip NVMUpdatePackage_700_Series.zip

Archive: NVMUpdatePackage_700_Series.zip

inflating: 700Series_NVMUpdatePackage_v7_10_EFI.zip

inflating: 700Series_NVMUpdatePackage_v7_10_ESX.tar.gz

inflating: 700Series_NVMUpdatePackage_v7_10_FreeBSD.tar.gz

inflating: 700Series_NVMUpdatePackage_v7_10_Linux.tar.gz

inflating: 700Series_NVMUpdatePackage_v7_10_Windows.exe
