had issues with MDS-related microcode update that may lead to a system hang

Intel Skylake Scalable Platform CPU models that belong to Workstation and HEDT
|
||||
(Basin Falls) segment (SKL-W/X, family 6, model 85, stepping 4) had reports
|
||||
of system hangs on reboot when revision 0x2000065 of microcode, that was included
|
||||
from microcode-20191112 update up to microcode-20200520 update, was applied[1].
|
||||
In order to address this, microcode update to the newer revision had been
|
||||
disabled by default on these systems, and the previously published microcode
|
||||
revision 0x2000064 is used by default for the OS-driven microcode update.
|
||||
|
||||
Since revision 0x2006906 (included with the microcode-20200609 release)
|
||||
it is reported that the issue is no longer present, so the newer microcode
|
||||
revision is enabled by default now (but can be disabled explicitly; see below).

version, please create a file "disallow-intel-06-8e-9e-0x-0xca" inside
|
||||
/lib/firmware/<kernel_version> directory, run
|

"/usr/libexec/microcode_ctl/update_ucode" to update firmware directory
|
||||
used for late microcode updates, and run "dracut -f --kver <kernel_version>"
|

||||
/usr/libexec/microcode_ctl/update_ucode
|
||||
dracut -f --kver 3.10.0-862.9.1
|
||||
|
||||
To disable usage of the newer microcode revision for all kernels, please create
|
||||
file "/etc/microcode_ctl/ucode_with_caveats/disallow-intel-06-8e-9e-0x-0xca",
|

run "/usr/libexec/microcode_ctl/update_ucode" to update firmware directories
|
||||
used for late microcode updates, and run "dracut -f --regenerate-all"

The microcode_ctl package contains microcode files (vendor-provided binary data
|
||||
and/or code in proprietary format that affects behaviour of a device) for Intel
|
||||
CPUs that may be loaded into the CPU during boot.
|
||||
|
||||
The microcode_ctl package contains provisions for some issues related
|
||||
to microcode loading. While those provisions are expected to suit most users,
|
||||
several knobs are available in order to provide ability to override the default
|
||||
behaviour.
|
||||
|
||||
|
||||
General behaviour
|
||||
=================
|
||||
In RHEL 8 (as well as RHEL 7 before it), there are currently two main handlers
|
||||
for CPU microcode update:
|
||||
* Early microcode update. It uses GenuineIntel.bin or AuthenticAMD.bin file
|
||||
placed at the beginning of an initramfs image
|
||||
(/boot/initramfs-KERNEL_VERSION.img, where "KERNEL_VERSION" is a kernel
|
||||
version in the same format as provided by "uname -r") as a source
|
||||
of microcode data, and is performed very early during the boot process
|
||||
(if the relevant microcode file is available in the aforementioned file).
|
||||
* On-demand (late) microcode update. It can be triggered by writing "1" to
|
||||
/sys/devices/system/cpu/microcode/reload file (provided my the "microcode"
|
||||
module). It relies on request_firmware infrastructure, which searches (and
|
||||
loads, if found) microcode from a file present in one of the following
|
||||
directories (in the search order):
|
||||
/lib/firmware/updates/KERNEL_VERSION/
|
||||
/lib/firmware/updates/
|
||||
/lib/firmware/KERNEL_VERSION/
|
||||
/lib/firmware/
|
||||
(there is also an additional directory that can be configured via the
|
||||
"fw_path_para" module option of the "firmware_class" module; as this module
|
||||
is built-in in RHEL kernel, a boot parameter "firmware_class.fw_path_para"
|
||||
should be used for that purpose; this is out of the document's scope, however)
|
||||
|
||||
The firmware for Intel CPUs is searched in "intel-ucode" subdirectory, and for
|
||||
AMD CPUs, a file under "amd-ucode" is searched.
|
||||
|
||||
For Intel CPUs, the name of the specific microcode file the kernel tries to load
|
||||
has the format "FF-MM-SS", where "FF" is the family number, "MM" is the model
|
||||
number, and "SS" is the stepping. All those numbers are zero-filled to two digits
|
||||
and are written in hexadecimal (letters are in the lower case). For AMD CPUs,
|
||||
the file name has the format "microcode_amd_famFFh.bin", where "FF" is the
|
||||
family number, written in hexadecimal, letters are in the lower case, not
|
||||
zero-filled.
|
||||
|
||||
The early microcode is placed into initramfs image by the "dracut" script, which
|
||||
scans the aforementioned subdirectories of the configured list of firmware
|
||||
directories (by default, the list consists of two directories in RHEL 8,
|
||||
"/lib/firmware/updates" and "/lib/firmware").
|
||||
|
||||
In RHEL 8, AMD CPU microcode is shipped as a part of the linux-firmware package,
|
||||
and Intel microcode is shipped as a part of the microcode_ctl package.
|
||||
|
||||
The microcode_ctl package currently includes the following:
|
||||
* Intel CPU microcode files, placed in /usr/share/microcode_ctl/intel-ucode
|
||||
directory (currently there are none);
|
||||
* A dracut module, /usr/lib/dracut/modules.d/99microcode_ctl-fw_dir_override,
|
||||
that controls which additional firmware directories will be added to dracut's
|
||||
default configuration;
|
||||
* A dracut configuration file, /usr/lib/dracut/dracut.conf.d/01-microcode.conf,
|
||||
that enables inclusion of early microcode to the generated initramfs
|
||||
in dracut;
|
||||
* A dracut configuration file,
|
||||
/usr/lib/dracut/dracut.conf.d/99-microcode-override.conf, that provides a way
|
||||
to quickly disable 99microcode_ctl-fw_dir-override dracut module;
|
||||
* A systemd service file, microcode.service, that triggers microcode reload
|
||||
late during boot;
|
||||
* A set of directories in /usr/share/microcode_ctl/ucode_with_caveats, each
|
||||
of which contains configuration and related data for various caveats related
|
||||
to microcode:
|
||||
* readme - description of caveat and related information,
|
||||
* config - caveat configuration file, with syntax as described in "Caveat
|
||||
configuration" section below,
|
||||
* intel-ucode - directory containing microcode files related to the caveat;
|
||||
* A set of support scripts, placed in /usr/libexec/microcode_ctl:
|
||||
* "check_caveats" is an utility script that performs checks of the target
|
||||
kernel (and running CPU) in accordance with caveat configuration files
|
||||
in ucode_with_caveats directory and reports whether it passes them or not,
|
||||
* "reload_microcode" is a script that is called by microcode.service and
|
||||
triggers microcode reloading (by writing "1" to
|
||||
/sys/devices/system/cpu/microcode/reload) if the running kernel passes
|
||||
check_caveats checks,
|
||||
* "update_ucode" is a script that populates symlinks to microcode files
|
||||
in /lib/firmware, so it can be picked up by relevant kernels for the late
|
||||
microcode loading.
|
||||
|
||||
Also, microcode_ctl RPM includes triggers that run update_ucode script on every
|
||||
installation or removal of a kernel RPM in order to provide microcode files
|
||||
for newly installed kernels and cleanup symlinks for the uninstalled ones.
|
||||
|
||||
|
||||
Caveat configuration
|
||||
--------------------
|
||||
There is a directory for each caveat under
|
||||
/usr/share/microcode_ctl/ucode_with_caveats, containing the following files:
|
||||
* "config", a configuration file for the caveat;
|
||||
* "readme", that contains description of the caveat;
|
||||
* set of related associated microcode files.
|
||||
|
||||
"config" file is a set of lines each containing option name and its value,
|
||||
separated by white space. Currently, the following options are supported:
|
||||
* "model" option, which has format "VENDOR_ID FF-MM-SS", that specifies
|
||||
to which CPU model the caveat is applicable (check_caveats ignores caveats
|
||||
with non-matching models if "-m" option is passed to it). Can be set
|
||||
in the configuration file only once (the last provided value is used).
|
||||
* "vendor" option specifies CPUs of which vendor (as provided
|
||||
in the /proc/cpuinfo file) the caveat is applicable to (check_caveats
|
||||
ignores caveats with non-matching models when it is invoked with "-m"
|
||||
option). Can be set in the configuration file only once.
|
||||
* "path" is a glob pattern that specifies set of microcode files associated
|
||||
with the caveat as a relative path to the caveat directory. This option
|
||||
is used for populating files in /lib/firmware by update_ucode script and
|
||||
for matching microcode file when dracut is run in host-only mode
|
||||
(as in that case it uses only the first directory in firmware directory list
|
||||
to look for the microcode file applicable to the host CPU). Can be set
|
||||
in the configuration file multiple times.
|
||||
* "kernel" is a minimal kernel version that supports proper handling
|
||||
of the related microcode files during late microcode load. It may be
|
||||
provided in one of the following formats that affect the way it is compared
|
||||
to the running kernel version:
|
||||
* A.B.C (where A, B, and C are decimal numbers), "upstream version". In this
|
||||
case, simple version comparison against the respective part of the running
|
||||
kernel version is used, and the running kernel version should be greater
|
||||
or equal than the version provided in the configuration option in order
|
||||
for comparison to succeed (that is, the first part, major version number,
|
||||
of the running kernel version should be greater than the value provided
|
||||
in the configuration option, or those should be equal and the second part,
|
||||
minor version number, should be greater than the minor version number
|
||||
of the kernel version provided in the configuration option, or the first
|
||||
two parts should be equal and the third part, patch level, should
|
||||
be greater or equal the patch level of the version in the configuration
|
||||
option).
|
||||
* A.B.C-Y (where A, B, C, and Y are decimal numbers), "Y-stream version".
|
||||
In this case, A.B.C part should be equal, and Y part of the running kernel
|
||||
version should be greater or equal than the Y part of the configuration
|
||||
option version in order to satisfy the comparison requirement.
|
||||
* A.B.C-Y.Z1.Z2 (where A, B, C, Y, Z1, and Z2 are decimal numbers),
|
||||
"Z-stream version". In this case, A.B.C-Y part should be equal and Z1.Z2
|
||||
part of the running kernel should be greater or equal than the respective
|
||||
part of the configuration option version (when compared as a version)
|
||||
for comparison to succeed.
|
||||
Kernel version check passed if at least one comparison of the running kernel
|
||||
version against a kernel version provided in a configuration option
|
||||
succeeded. The "kernel" configuration option can be provided
|
||||
in the configuration file multiple times.
|
||||
* "kernel_early" is a minimal kernel version that supports proper handling
|
||||
of the related microcode during early microcode load. The format of the
|
||||
option and its semantics is similar to the "kernel" configuration options.
|
||||
This option can be provided multiple times as well.
|
||||
* "mc_min_ver_late" is the minimal version of the currently loaded microcode
|
||||
on the CPU (as reported in /proc/cpuinfo) that supports late microcode
|
||||
update. Microcode update will be attempted only if the currently loaded
|
||||
microcode version is greater or equal the microcode version provided
|
||||
in the configuration option. Can be set in the configuration file only once.
|
||||
* "disable" is a way to disable a specific caveat from inside its
|
||||
configuration. Argument for the argument is a list of stages ("early",
|
||||
"late") for which the caveat should be disable. The configuration option
|
||||
can be provided multiple times in a configuration file.
|
||||
* "blacklist" is a marker for a start of list of blacklisted model names,
|
||||
one model name per line. The model name of the running CPU (as reported
|
||||
in /proc/cpuinfo) is compared against the names in the provided list, and,
|
||||
if there is a match, caveat check fails.
|
||||
* "pci_config_val" performs check for specific values in selected parts
|
||||
of configuration space of specified PCI devices. If "-m" option
|
||||
is not specified, then the actual check is skipped, and the check returns
|
||||
result in accordance with the provided "mode" option (se below). Check
|
||||
arguments are a white-space-separated list of "key=value" pairs.
|
||||
The following keys are supported:
|
||||
* "domain" - PCI domain number, or "*" (an asterisk) for any domain.
|
||||
Default is "*".
|
||||
* "bus" - PCI bus number, or "*" (an asterisk) for any bus. Default is "*".
|
||||
* "device" - PCI device number, or "*" (an asterisk) for any device.
|
||||
Default is "*".
|
||||
* "function" - PCI function number, or "*" (an asterisk) for any function.
|
||||
Default is "*".
|
||||
* "vid" - PCI vendor ID, or empty string for any vendor ID. Default
|
||||
is empty string.
|
||||
* "did" - PCI device ID, or empty string for any device ID. Default
|
||||
is empty string.
|
||||
* "offset" - offset in device's configuration space where the value resides.
|
||||
Default is 0.
|
||||
* "size" - field size. Possible values are 1, 2, 4, or 8. Default is 4.
|
||||
* "mask" - mask applied to the values during the check. Default is 0.
|
||||
* "val" - comma-separated list of matching values. Default is 0.
|
||||
* "mode" - check mode, the way matches are interpreted:
|
||||
* "success-any" - check succeeds if there was at least one match,
|
||||
otherwise it fails.
|
||||
* "success-all" - check succeeds if there was at least one device checked
|
||||
and all the checked devices have matches, otherwise the check fails.
|
||||
* "fail-any" - check fails if there was at least one match, otherwise
|
||||
it succeeds.
|
||||
* "fail-all" - check fails if there was at least one device checked
|
||||
and all the checked devices have matches, otherwise the check succeeds.
|
||||
Default is "success-any".
|
||||
An example of a check:
|
||||
pci_config_val mode=success-all device=30 function=3 vid=0x8086 did=0x2083 offset=0x84 size=4 mask=0x38 val=0x38,0x18,0x8
|
||||
It interprets 4 bytes at offset 0x84 of special files "config" under
|
||||
directories that match glob pattern "/sys/bus/pci/devices/*:*:1e.3"
|
||||
as an unsigned integer value, applies mask 0x38 (thus selecting bit 5..3
|
||||
of it) and checks whether it is one of the values 0x38, 0x18, or 0x8 (0b111,
|
||||
0b011, or 0b001 in bits 5..3, respectively); if there are such files,
|
||||
and all the checked values in every checked file has matched at least one
|
||||
of the aforementioned value, then the check is successful, otherwise
|
||||
it fails (in accordance with "mode=success-all" semantics). This check fails
|
||||
if "-m" option is not specified.
|
||||
* "dmi" performs checks for specific values available in DMI sysfs files
|
||||
(present under /sys/devices/virtual/dmi/id/). The check fails if file
|
||||
is not readable. If "-m" option is specified, then the actual check
|
||||
is skipped, and the check returns value in accordance with "no-model-mode"
|
||||
parameter value (see below). Check arguments are a white-space-separated
|
||||
list of "key=value" pairs. The following keys are supported:
|
||||
* "key" - DMI file to check. Value can be one of the following: bios_date,
|
||||
bios_vendor, bios_version, board_asset_tag, board_name, board_serial,
|
||||
board_vendor, board_version, chassis_asset_tag, chassis_serial,
|
||||
chassis_type, chassis_vendor, chassis_version, product_family,
|
||||
product_name, product_serial, product_uuid, product_version, sys_vendor.
|
||||
Default is empty string.
|
||||
* "val" - a string to match DMI data against. Can be enclosed in single
|
||||
or double quotes. Default is empty string.
|
||||
* "mode" - check mode, the way matches are interpreted:
|
||||
* "success-equal" - returns 0 if the value present in the file
|
||||
with the name supplied via the "key" parameter file under
|
||||
/sys/devices/virtual/dmi/id/ is equal to the value supplied as a value
|
||||
of "val" parameter, otherwise 1.
|
||||
* "success-equal" - returns 1 if the value present in the file
|
||||
with the name supplied via the "key" parameter file under
|
||||
/sys/devices/virtual/dmi/id/ is equal to the value supplied as a value
|
||||
of "val" parameter, otherwise 0.
|
||||
Default is "success-any".
|
||||
* "no-model-mode" - return value if model filter ("-m" option)
|
||||
is not enabled:
|
||||
* "success" - return 0.
|
||||
* "fail" - return 1.
|
||||
Default is "success".
|
||||
An example of a check:
|
||||
dmi mode=fail-equal no-model-mode=success key=bios_vendor val="Dell Inc."
|
||||
It checks file /sys/devices/virtual/dmi/id/bios_vendor and fails if its
|
||||
content is "Dell Inc." (without quotes). It succeeds if "-m" option
|
||||
is not enabled.
|
||||
|
||||
|
||||
check_caveats script
|
||||
--------------------
|
||||
"check_caveats" is an utility script (called by update_ucode, reload_microcode,
|
||||
dracut module) that performs checks of the target kernel (and running CPU)
|
||||
in accordance with caveat configuration files in directory
|
||||
"/usr/share/microcode_ctl/ucode_with_caveats", and returns information, whether
|
||||
the system passes the checks, or not.
|
||||
|
||||
Usage:
|
||||
check_caveats [-e] [-k TARGET_KVER] [-c CONFIG]* [-m] [-v]'
|
||||
|
||||
Options:
|
||||
-e - check for early microcode load possibility (instead of late microcode
|
||||
load). "kernel_early" caveat configuration options are used for checking
|
||||
instead of "kernel", and "mc_min_ver_late" is not checked.
|
||||
-k - target kernel version to check against, $(uname -r) is used otherwise.
|
||||
-c - caveat(s) to check, all caveat configurations found inside
|
||||
$MC_CAVEATS_DATA_DIR are checked otherwise.
|
||||
-m - ignore caveats that do not apply to the current CPU model.
|
||||
-v - verbose output.
|
||||
|
||||
Environment:
|
||||
MC_CAVEATS_DATA_DIR - directory that contains caveats configurations,
|
||||
"/usr/share/microcode_ctl/ucode_with_caveats"
|
||||
by default.
|
||||
FW_DIR - directory containing firmware files (per-kernel configuration
|
||||
overrides are checked there), "/lib/firmware" by default.
|
||||
CFG_DIR - directory containing global caveats overrides,
|
||||
"/etc/microcode_ctl/ucode_with_caveats" by default.
|
||||
|
||||
Output:
|
||||
Script returns information about caveats check results. Output has a format
|
||||
of "KEY VALUE1 VALUE2 ..." with KEY defining the semantics of the VALUEs.
|
||||
Currently, the following data is issued:
|
||||
- "cfgs" - list of caveats that have been processed (and not skipped
|
||||
due to missing "config", "readme", or a disallow-* override described
|
||||
below);
|
||||
- "skip_cfgs" - list of caveats that have been skipped (due to missing
|
||||
config/readme file, or because of overrides);
|
||||
- "paths" - list of glob patterns matching files associated with caveats
|
||||
that have been processed;
|
||||
- "ok_cfgs" - list of caveat configurations that have all the checks passed
|
||||
(or have enforced by one of force-* overrides described below);
|
||||
- "ok_paths" - list of glob patterns associated with caveat files from
|
||||
the "ok_cfgs" list;
|
||||
- "fail_cfgs" - list of caveats that have one of the checks failed.
|
||||
- "fail_paths" - list of glob patterns associated with caveats from the
|
||||
"fail_cfgs" list.
|
||||
|
||||
Return value:
|
||||
- 0 in case caveats check has passed, 1 otherwise.
|
||||
- In "-d" mode, 0 is always returned.
|
||||
|
||||
Overrides:
|
||||
|
||||
When check_caveats perform its checks, it also checks for presence of files
|
||||
in specific places, and, if they exist, check_caveats skips a caveat or ignores
|
||||
its checks; that mechanism allows overriding the information provided
|
||||
in configuration on local systems and affect the behaviour of the microcode
|
||||
update process.
|
||||
|
||||
Current list of overrides (where $FW_DIR and $CFG_DIR are the environment
|
||||
options described earlier; $kver - the currently processed kernel version,
|
||||
$s is the requested stage ("early" or "late"), $cfg is the caveat directory
|
||||
name):
|
||||
$FW_DIR/$kver/disallow-$s-$cfg - skip a caveat for the requested stage for
|
||||
a specific kernel version..
|
||||
$FW_DIR/$kver/force-$s-$cfg - apply a specific caveat file for a specific
|
||||
kernel version for the requested stage without
|
||||
performing any checks.
|
||||
$FW_DIR/$kver/disallow-$cfg - skip a caveat for any stage for a specific
|
||||
kernel version.
|
||||
$FW_DIR/$kver/force-$cfg - apply a specific caveat for any stage
|
||||
for a specific kernel version without checks.
|
||||
$FW_DIR/$kver/disallow-$s - skip all caveats for a specific stage
|
||||
for a specific kernel version.
|
||||
$CFG_DIR/disallow-$s-$cfg - skip a caveat for a specific stage for all
|
||||
kernel versions.
|
||||
$FW_DIR/$kver/force-$s - apply all caveats for a specific stage
|
||||
for a specific kernel version without checks.
|
||||
$CFG_DIR/force-$s-$cfg - apply a specific caveat for a specific stage for
|
||||
all kernel versions without checks.
|
||||
$FW_DIR/$kver/disallow - skip all caveats for all stages for a specific
|
||||
kernel version.
|
||||
$CFG_DIR/disallow-$cfg - skip a caveat for all stages for all kernel
|
||||
versions.
|
||||
$FW_DIR/$kver/force - apply all caveats for all stages for a specific kernel
|
||||
version without checks.
|
||||
$CFG_DIR/force-$cfg - apply a caveat for all stages for all kernel versions
|
||||
without checks.
|
||||
$CFG_DIR/disallow-$s - skip all caveat for all kernel versions
|
||||
for a specific stage.
|
||||
$CFG_DIR/force-$s - apply all caveats for all kernel versions for specific
|
||||
stage without checks.
|
||||
$CFG_DIR/disallow - skip all caveats for all stages for all kernel versions
|
||||
(disable everything).
|
||||
$CFG_DIR/force - force all caveats for all stages for all kernel versions
|
||||
(enable everything).
|
||||
|
||||
The "apply" action above means creating symlinks in /lib/firmware by
|
||||
update_ucode in case of the "late" stage and adding caveat directory to the list
|
||||
of firmware directories by dracut plugin in case of the "early" stage.
|
||||
|
||||
The files are checked for existence until the first match, so more specific
|
||||
overrides can override more broad ones.
|
||||
|
||||
Also, a caveat is ignored if it lacks either config or readme file.
|
||||
|
||||
|
||||
update_ucode script
|
||||
-------------------
|
||||
"update_ucode" populates symlinks to microcode files in accordance with caveats
|
||||
configuration. It enables late microcode loading that is invoked by triggering
|
||||
/sys/devices/system/cpu/microcode/reload file. Since caveats depend
|
||||
on the kernel version, symlinks are populated inside
|
||||
"/lib/firmware/KERNEL_VERSION" directory for each installed kernel.
|
||||
As a consequence, this script is triggered upon each kernel package installation
|
||||
and removal.
|
||||
|
||||
The script has two parts: common and kernel-version-specific.
|
||||
|
||||
During the common part, files are populated from
|
||||
/usr/share/microcode_ctl/intel-ucode in /lib/firmware/intel-ucode. There are
|
||||
several possibilities to affect the process:
|
||||
* Presence of "/etc/microcode_ctl/intel-ucode-disallow" file leads to skipping
|
||||
the common part of the script.
|
||||
* The same for "/lib/firmware/intel-ucode-disallow".
|
||||
|
||||
During the kernel-version-specific part, each caveat is checked against every
|
||||
kernel version, and those combinations, for which caveat check succeeds,
|
||||
gets the symlinks to the associated microcode files populated.
|
||||
* Absence of "/lib/firmware/KERNEL_VERSION/readme-CAVEAT" prevents update_ucode
|
||||
from removing symlinks related to the caveat for specific kernel version.
|
||||
* Since the check is being done by check_caveats, all the overrides that
|
||||
described there also stay.
|
||||
|
||||
Usage:
|
||||
update_ucode [--action {add|remove|refresh|list}] [--kernel KERNELVER]*
|
||||
[--verbose] [--dry-run] [--cleanup intel_ucode caveats_ucode]
|
||||
[--skip-common] [--skip-kernel-specific]
|
||||
|
||||
Options:
|
||||
--action - action to perform. Currently, the following actions are supported:
|
||||
* "add" - create new symlinks.
|
||||
* "remove" - remove old symlinks that are no longer needed.
|
||||
* "refresh" - re-populate symlinks.
|
||||
* "list" - list files under control of update_ucode.
|
||||
By default, "refresh" action is executed.
|
||||
--kernel - kernel version to process. By default, list of kernel versions
|
||||
is formed based on contents of /lib/firmware and /lib/modules
|
||||
directories.
|
||||
--verbose - verbose output.
|
||||
--dry-run - do not call commands, just print the invocation lines.
|
||||
--cleanup - cleanup mode. Used by post-uninstall script during package
|
||||
upgrades. Removes excess files in accordance to the contents
|
||||
of the files provided in the arguments to the option.
|
||||
--skip-common - do not process /lib/firmware directory.
|
||||
--skip-kernel-specific - do not process /lib/firmware/KERNEL_VERSION
|
||||
directories.
|
||||
|
||||
Return value:
|
||||
0 on success, 1 on error.
|
||||
|
||||
|
||||
reload_microcode script
|
||||
-----------------------
|
||||
"reload_microcode" is a script that is called by microcode.service and
|
||||
triggers late microcode reloading (by writing "1" to
|
||||
/sys/devices/system/cpu/microcode/reload) if the following check are passed:
|
||||
* the microcode update performed not in a virtualised environment;
|
||||
* running kernel passes "check_caveats" checks that applicable to the current
|
||||
CPU model.
|
||||
|
||||
For a virtualised environment check, the script searches the "/proc/cpuinfo"
|
||||
file for presence of the "hypervisor" flag among CPU features (it corresponds
|
||||
to a CPUID feature bit set by hypervisors in order to inform that the kernel
|
||||
operates inside a virtual machine). This check can be overridden and skipped
|
||||
by creation of a file "/etc/microcode_ctl/ignore-hypervisor-flag".
|
||||
|
||||
The script has no options and always returns 0.
|
||||
|
||||
|
||||
99microcode_ctl-fw_dir_override dracut module
|
||||
---------------------------------------------
|
||||
This dracut module injects directories with microcode files for caveats
|
||||
that pass "early" check_caveats check (with "-e" flag). In addition
|
||||
to "check_caveats" overrides, the following abilities to control module's
|
||||
behaviour are present:
|
||||
* Presence of one of the following files:
|
||||
- /etc/microcode_ctl/ucode_with_caveats/skip-host-only-check
|
||||
- /etc/microcode_ctl/ucode_with_caveats/skip-host-only-check-$cfg
|
||||
- /lib/firmware/$kver/skip-host-only-check
|
||||
- /lib/firmware/$kver/skip-host-only-check-$cfg
|
||||
(where "$kver" is the kernel version in question and "$cfg" is the caveat
|
||||
directory name) allows skipping matching of microcode file name when dracut's
|
||||
Host-Only mode is enabled.
|
||||
|
||||
When caveats_check succeeds, caveats directory (not its possibly populated
|
||||
version for late microcode update: "/lib/firmware/KERNEL_VERSION";
|
||||
it is done so in order
|
||||
to have ability to configure list of caveats enabled for early and late
|
||||
microcode update, independently) is added to dracut's list of firmware search
|
||||
directories.
|
||||
|
||||
The module can be disabled by running dracut with
|
||||
"-o microcode_ctl-fw_dir_override" (for one-time exclusion), or it can
|
||||
be disabled permanently by uncommenting string
|
||||
"omit_dracutmodules+=' microcode_ctl-fw_dir_override '" in
|
||||
/usr/lib/dracut/dracut.conf.d/99-microcode-override.conf configuration file.
|
||||
|
||||
See dracut(8), section "Omitting dracut Modules", and dracut.conf(5), variable
|
||||
"omit_dracutmodules" for additional information.

Caveats
|
||||
=======
|
||||
|
||||
Intel Broadwell-EP/EX ("BDX-ML B/M/R0") caveat
|
||||
----------------------------------------------
|
||||
Microcode update process on Intel Broadwell-EP/EX CPUs (BDX-ML B/M/R0,
|
||||
family 6, model 79, stepping 1) has issues that lead to system instability.
|
||||
A series of changes for the Linux kernel has been developed in order to work
|
||||
around those issues; however, as it turned out, some systems have issues even
|
||||
when a microcode update performed on a kernel that contains those changes.
|
||||
As a result, microcode update for this CPU model is disabled by default;
|
||||
the microcode file, however, is still shipped as a part of microcode_ctl
|
||||
package and can be used for performing a microcode update if it is enforced
|
||||
via the aforementioned overrides. (See the sections "check_caveats script"
|
||||
and "reload_microcode script" for details.)
|
||||
|
||||
Caveat name: intel-06-4f-01
|
||||
|
||||
Affected microcode: intel-ucode/06-4f-01.
|
||||
|
||||
Mitigation: microcode loading is disabled for the affected CPU model.
|
||||
|
||||
Minimum versions of the kernel package that contain the aforementioned patch
|
||||
series:
|
||||
- Upstream/RHEL 8: 4.17.0
|
||||
- RHEL 7.6 onwards: 3.10.0-894
|
||||
- RHEL 7.5: 3.10.0-862.6.1
|
||||
- RHEL 7.4: 3.10.0-693.35.1
|
||||
- RHEL 7.3: 3.10.0-514.52.1
|
||||
- RHEL 7.2: 3.10.0-327.70.1
|
||||
- RHEL 6.10: 2.6.32-754.1.1
|
||||
- RHEL 6.7: 2.6.32-573.58.1
|
||||
- RHEL 6.6: 2.6.32-504.71.1
|
||||
- RHEL 6.5: 2.6.32-431.90.1
|
||||
- RHEL 6.4: 2.6.32-358.90.1
|
||||
|
||||
|
||||
Early microcode load inside a virtual machine
|
||||
---------------------------------------------
|
||||
RHEL 8 kernel supports performing microcode update during early boot stage
|
||||
from a cpio archive placed at the beginning of the initramfs image. However,
|
||||
when an early microcode update is attempted inside some virtualised
|
||||
environments, that may result in unexpected system behaviour.
|
||||
|
||||
Caveat name: intel
|
||||
|
||||
Affected microcode: all.
|
||||
|
||||
Mitigation: early microcode loading is disabled for all CPU models on kernels
|
||||
without the fix.
|
||||
|
||||
Minimum versions of the kernel package that contain the fix:
|
||||
- Upstream/RHEL 8: 4.10.0
|
||||
- RHEL 7.6 onwards: 3.10.0-930
|
||||
- RHEL 7.5: 3.10.0-862.14.1
|
||||
- RHEL 7.4: 3.10.0-693.38.1
|
||||
- RHEL 7.3: 3.10.0-514.57.1
|
||||
- RHEL 7.2: 3.10.0-327.73.1
|
||||

||||
|
||||
Intel Sandy Bridge-E/EN/EP caveat
|
||||
---------------------------------
|
||||
Microcode revision 0x718 for Intel Sandy Bridge-E/EN/EP (SNB-EP, family 6,
|
||||
model 45, stepping 7), that was released to address MDS vulnerability,
|
||||
and was available from microcode-20190618 up to microcode-20190508 release)
|
||||
could lead to system instability[1][2]. In order to address this,
|
||||
this microcode update was not used and the previous microcode revision
|
||||
was provided instead by default; the microcode file, however, was still shipped
|
||||
as part of microcode_ctl package and could be used for performing a microcode
|
||||
update if it is enforced via the aforementioned overrides. With the release
|
||||
of 0x71a revision of the microcode (as art of microcode-20200520 release)
|
||||
that aims at fixing the aforementioned stability issue, the latest microcode
|
||||
revision is again used by default; it is still provided via the caveat
|
||||
mechanism, hovewer, in order to enable ability to disable it in case such
|
||||
a need arises. (See the sections "check_caveats script" and "reload_microcode
|
||||
script" for details regarding caveats mechanism operation.)

Affected microcode: intel-ucode/06-2d-07.
|
||||
|

as part of "intel" caveat.
|
||||
|
||||
|
||||
Intel Skylake-SP/W/X caveat
|
||||
---------------------------
|
||||
Microcode revision 0x2000065 (that was provided with microcode releases
|
||||
microcode-20191112 up to microcode-20200520) for some CPU models that belong
|
||||
to Intel Skylake Scalable Platform (SKL-W/X, family 6, model 85, stepping 4,
|
||||
Workstation/HEDT segments) could lead to hangs during reboot[1]. In order
|
||||
to address this, by default this microcode update was disabled by default and
|
||||
and the previous 0x2000064 microcode revision was used instead; the microcode
|
||||
file with, however, is still shipped as part of microcode_ctl package and can
|
||||
be used for performing a microcode update if it is enforced
|
||||
via the aforementioned overrides. With the availability of 0x2006906 revision
|
||||
of the microcode (in the microcode-20200609 release) that fixes
|
||||
the aforementioned issue, the latest microcode revision is again used
|
||||
by default; it is still provided via caveat mechanism, hovewer, in order
|
||||
to enable ability to disable it in case such a need arises. (See the sections
|

Intel Skylake-U/Y/H/S/Xeon E3 v5 caveats
|
||||
----------------------------------------
|
||||
Some Intel Skylake CPU models (SKL-U/Y, family 6, model 78, stepping 3;
|
||||
and SKL-H/S/Xeon E3 v5, family 6, model 94, stepping 3) have reports of system
|
||||
hangs when revision 0xdc of microcode, that is included in microcode-20200609
|
||||
update to address CVE-2020-0543, CVE-2020-0548, and CVE-2020-0549,
|
||||
is applied[1][2]. In order to address this, microcode update to the newer
|
||||
revision has been disabled by default on these systems, and the previously
|
||||
published microcode revision 0xd6 is used instead; the newer microcode files,
|
||||
however, are still shipped as part of microcode_ctl package and can be used
|
||||
for performing a microcode update if they are enforced via the aforementioned
|
||||
overrides. (See the sections "check_caveats script" and "reload_microcode
|

Dell caveats
|
||||
------------
|
||||
Some Dell systems that use some models of Intel CPUs are susceptible to hangs
|
||||
and system instability during or after microcode update to revision 0xc6/0xca
|
||||
(included as part of microcode-20191113/microcode-20191115 update that addressed
|
||||
CVE-2019-0117, CVE-2019-0123, CVE-2019-11135, and CVE-2019-11139)
|
||||
and/or revision 0xd6 (included as part of microcode-20200609 update
|
||||
that addressed CVE-2020-0543, CVE-2020-0548, and CVE-2020-0549)
|
||||
[1][2][3][4][5][6]. In order to address this, microcode update to the newer
|
||||
revision has been disabled by default on these systems, and the previously
|
||||
published microcode revisions 0xae/0xb4/0xb8 are used by default
|
||||
for the OS-driven microcode update.

Intel Tiger Lake-UP3/UP4 caveat
|
||||
-------------------------------
|
||||
Some systems with Intel Tiger Lake-UP3/UP4 CPUs (TGL, family 6, model 140,
|
||||
stepping 1) have reports of system hangs when a microcode update,
|
||||
that is included since microcode-20201110 release, is applied[1].
|
||||
In order to address this, microcode update to a newer revision has been disabled
|
||||
by default on these systems; the newer microcode file, however, is still shipped
|
||||
as a part of microcode_ctl package and can be used for performing a microcode
|

This kernel doesn't handle early microcode load properly (it tries to load

microcode even in virtualised environment, which may lead to a panic on some

hypervisors), thus the microcode files have not been added to the initramfs

image. Please update your kernel to one of the following:
|

RHEL 7.5: kernel-3.10.0-862.14.1 or newer;

RHEL 7.4: kernel-3.10.0-693.38.1 or newer;

Older RHEL 7 kernels try to early load microcode even inside virtual
|
||||
machine, which may lead to panic on some hypervisors. In order to circumvent
|
||||
that, microcode is installed into a kernel-version-specific directory (which
|
||||
is not scanned by the dracut script, that constructs early microcode binary
|
||||
in initramfs, by default), and path to microcode files provided only in case
|
||||
initramfs is generated for the kernel version that properly handles early
|
||||
microcode inside a virtual machine (i.e. do not attempts yo load it).
|
||||
The versions of the kernel package that properly handle early microcode load
|
||||
inside a virtual machine are as follows:
|
||||
* RHEL 7.6 onwards: kernel-3.10.0-930 or newer;
|
||||
* RHEL 7.5: kernel-3.10.0-862.14.1 or newer;
|
||||
* RHEL 7.4: kernel-3.10.0-693.38.1 or newer;
|
||||
* RHEL 7.3: kernel-3.10.0-514.57.1 or newer;
|
||||
* RHEL 7.2: kernel-3.10.0-327.73.1 or newer.
|
||||
RHEL 8 kernels are not affected.
|
||||
|
||||
If you want to avoid early load of microcode for a specific kernel, please
|
||||
create "disallow-early-intel" file inside /lib/firmware/<kernel_version>
|
||||
directory and run dracut -f --kver "<kernel_version>":
|
||||
|
||||
touch /lib/firmware/3.10.0-862.9.1/disallow-early-intel
|
||||
dracut -f --kver 3.10.0-862.9.1
|
||||
|
||||
If you want to avoid early load of microcode for all kernels, please create
|
||||
"disallow-early-intel" file inside the "/etc/microcode_ctl/ucode_with_caveats"
|
||||
directory and run dracut -f --regenerate-all:
|
||||
|
||||
mkdir -p /etc/microcode_ctl/ucode_with_caveats
|
||||
touch /etc/microcode_ctl/ucode_with_caveats/disallow-early-intel
|
||||
dracut -f --regenerate-all
|
||||
|
||||
If you want to enforce early load of microcode for a specific kernel, please
|
||||
create "force-early-intel" file inside /lib/firmware/<kernel_version> directory
|
||||
and run dracut -f --kver "<kernel_version>":
|
||||
|
||||
touch /lib/firmware/3.10.0-862.9.1/force-early-intel
|
||||
dracut -f --kver 3.10.0-862.9.1
|
||||
|
||||
If you want to enforce early load of microcode for all kernels, please create
|
||||
"force-early-intel" file inside /etc/microcode_ctl/ucode_with_caveats
|
||||
directory and run dracut -f --kver "<kernel_version>":
|
||||
|
||||
mkdir -p /etc/microcode_ctl/ucode_with_caveats
|
||||
touch /etc/microcode_ctl/ucode_with_caveats/force-early-intel
|
||||
dracut -f --regenerate-all
|
||||
|
||||
In order to override the late load behaviour, the "early" part of file names
|
||||
should be replaced with "late" (and there is no need to call dracut
|
||||
in that case).
