+- * Speck64 variants are less secure, but on 32-bit processors are usually
+- * faster. The remaining variants (Speck32, Speck48, and Speck96) are even less
+- * secure and/or not as well suited for implementation on either 32-bit or

+From: David Ahern <dsahern@gmail.com>
+Date: Wed, 24 Oct 2018 08:32:49 -0700
+Subject: net: sched: Remove TCA_OPTIONS from policy
+
+Marco reported an error with hfsc:
+root@Calimero:~# tc qdisc add dev eth0 root handle 1:0 hfsc default 1
+Error: Attribute failed policy validation.
+
+Apparently a few implementations pass TCA_OPTIONS as a binary instead
+of nested attribute, so drop TCA_OPTIONS from the policy.
+
+Fixes: 8b4c3cdd9dd8 ("net: sched: Add policy validation for tc attributes")

-Subject: net: sched: Remove TCA_OPTIONS from policy
-
-Marco reported an error with hfsc:
-root@Calimero:~# tc qdisc add dev eth0 root handle 1:0 hfsc default 1
-Error: Attribute failed policy validation.
-
-Apparently a few implementations pass TCA_OPTIONS as a binary instead
-of nested attribute, so drop TCA_OPTIONS from the policy.
-
-Fixes: 8b4c3cdd9dd8 ("net: sched: Add policy validation for tc attributes")

+ This option adds a `CHECKSUM' target, which can be used in the iptables mangle
+- table.
++ table to work around buggy DHCP clients in virtualized environments.
+
+- You can use this target to compute and fill in the checksum in
+- a packet that lacks a checksum. This is particularly useful,
+- if you need to work around old applications such as dhcp clients,
+- that do not work well with checksum offloads, but don't want to disable
+- checksum offload in your device.
++ Some old DHCP clients drop packets because they are not aware
++ that the checksum would normally be offloaded to hardware and
++ thus should be considered valid.
++ This target can be used to fill in the checksum using iptables
++ when such packets are sent via a virtual network device.
+
+ To compile it as a module, choose M here. If unsure, say N.

+From: Anthony G. Basile <blueness@gentoo.org>
+
+This patch adds support for a restricted user-controlled namespace on
+tmpfs filesystem used to house PaX flags. The namespace must be of the
+form user.pax.* and its value cannot exceed a size of 8 bytes.
+
+This is needed even on all Gentoo systems so that XATTR_PAX flags
+are preserved for users who might build packages using portage on
+a tmpfs system with a non-hardened kernel and then switch to a
+hardened kernel with XATTR_PAX enabled.
+
+The namespace is added to any user with Extended Attribute support
+enabled for tmpfs. Users who do not enable xattrs will not have
+the XATTR_PAX flags preserved.

++What is it?
++-----------
++
++The framebuffer decorations are a kernel feature which allows displaying a
++background picture on selected consoles.
++
++What do I need to get it to work?
++---------------------------------
++
++To get fbcondecor up-and-running you will have to:
++ 1) get a copy of splashutils [1] or a similar program
++ 2) get some fbcondecor themes
++ 3) build the kernel helper program
++ 4) build your kernel with the FB_CON_DECOR option enabled.
++
++To get fbcondecor operational right after fbcon initialization is finished, you
++will have to include a theme and the kernel helper into your initramfs image.
++Please refer to splashutils documentation for instructions on how to do that.
++
++[1] The splashutils package can be downloaded from:
++ http://github.com/alanhaggai/fbsplash
++
++The userspace helper
++--------------------
++
++The userspace fbcondecor helper (by default: /sbin/fbcondecor_helper) is called by the
++kernel whenever an important event occurs and the kernel needs some kind of
++job to be carried out. Important events include console switches and video
++mode switches (the kernel requests background images and configuration
++parameters for the current console). The fbcondecor helper must be accessible at
++all times. If it's not, fbcondecor will be switched off automatically.
++
++It's possible to set path to the fbcondecor helper by writing it to
++/proc/sys/kernel/fbcondecor.
++
++*****************************************************************************
++
++The information below is mostly technical stuff. There's probably no need to
++read it unless you plan to develop a userspace helper.
++
++The fbcondecor protocol
++-----------------------
++
++The fbcondecor protocol defines a communication interface between the kernel and
++the userspace fbcondecor helper.
++
++The kernel side is responsible for:
++
++ * rendering console text, using an image as a background (instead of a
++ standard solid color fbcon uses),
++ * accepting commands from the user via ioctls on the fbcondecor device,
++ * calling the userspace helper to set things up as soon as the fb subsystem
++ is initialized.
++
++The userspace helper is responsible for everything else, including parsing
++configuration files, decompressing the image files whenever the kernel needs
++it, and communicating with the kernel if necessary.
++
++The fbcondecor protocol specifies how communication is done in both ways:
++kernel->userspace and userspace->helper.
++
++Kernel -> Userspace
++-------------------
++
++The kernel communicates with the userspace helper by calling it and specifying
++the task to be done in a series of arguments.
++
++The arguments follow the pattern:
++<fbcondecor protocol version> <command> <parameters>
++
++All commands defined in fbcondecor protocol v2 have the following parameters:
++ virtual console
++ framebuffer number
++ theme
++
++Fbcondecor protocol v1 specified an additional 'fbcondecor mode' after the
++framebuffer number. Fbcondecor protocol v1 is deprecated and should not be used.
++
++Fbcondecor protocol v2 specifies the following commands:
++
++getpic
++------
++ The kernel issues this command to request image data. It's up to the
++ userspace helper to find a background image appropriate for the specified
++ theme and the current resolution. The userspace helper should respond by
++ issuing the FBIOCONDECOR_SETPIC ioctl.
++
++init
++----
++ The kernel issues this command after the fbcondecor device is created and
++ the fbcondecor interface is initialized. Upon receiving 'init', the userspace
++ helper should parse the kernel command line (/proc/cmdline) or otherwise
++ decide whether fbcondecor is to be activated.
++
++ To activate fbcondecor on the first console the helper should issue the
++ FBIOCONDECOR_SETCFG, FBIOCONDECOR_SETPIC and FBIOCONDECOR_SETSTATE commands,
++ in the above-mentioned order.
++
++ When the userspace helper is called in an early phase of the boot process
++ (right after the initialization of fbcon), no filesystems will be mounted.
++ The helper program should mount sysfs and then create the appropriate
++ framebuffer, fbcondecor and tty0 devices (if they don't already exist) to get
++ current display settings and to be able to communicate with the kernel side.
++ It should probably also mount the procfs to be able to parse the kernel
++ command line parameters.
++
++ Note that the console sem is not held when the kernel calls fbcondecor_helper
++ with the 'init' command. The fbcondecor helper should perform all ioctls with
++ origin set to FBCON_DECOR_IO_ORIG_USER.
++
++modechange
++----------
++ The kernel issues this command on a mode change. The helper's response should
++ be similar to the response to the 'init' command. Note that this time the
++ console sem is held and all ioctls must be performed with origin set to
++ FBCON_DECOR_IO_ORIG_KERNEL.
++
++
++Userspace -> Kernel
++-------------------
++
++Userspace programs can communicate with fbcondecor via ioctls on the
++fbcondecor device. These ioctls are to be used by both the userspace helper
++(called only by the kernel) and userspace configuration tools (run by the users).
++
++The fbcondecor helper should set the origin field to FBCON_DECOR_IO_ORIG_KERNEL
++when doing the appropriate ioctls. All userspace configuration tools should
++use FBCON_DECOR_IO_ORIG_USER. Failure to set the appropriate value in the origin
++field when performing ioctls from the kernel helper will most likely result
++in a console deadlock.
++
++FBCON_DECOR_IO_ORIG_KERNEL instructs fbcondecor not to try to acquire the console
++semaphore. Not surprisingly, FBCON_DECOR_IO_ORIG_USER instructs it to acquire
++the console sem.
++
++The framebuffer console decoration provides the following ioctls (all defined in
++linux/fb.h):
++
++FBIOCONDECOR_SETPIC
++description: loads a background picture for a virtual console
++argument: struct fbcon_decor_iowrapper*; data: struct fb_image*
++notes:
++If called for consoles other than the current foreground one, the picture data
++will be ignored.
++
++If the current virtual console is running in a 8-bpp mode, the cmap substruct
++of fb_image has to be filled appropriately: start should be set to 16 (first
++16 colors are reserved for fbcon), len to a value <= 240 and red, green and
++blue should point to valid cmap data. The transp field is ingored. The fields
++dx, dy, bg_color, fg_color in fb_image are ignored as well.
++
++FBIOCONDECOR_SETCFG
++description: sets the fbcondecor config for a virtual console
++argument: struct fbcon_decor_iowrapper*; data: struct vc_decor*
++notes: The structure has to be filled with valid data.
++
++FBIOCONDECOR_GETCFG
++description: gets the fbcondecor config for a virtual console
++argument: struct fbcon_decor_iowrapper*; data: struct vc_decor*
++
++FBIOCONDECOR_SETSTATE
++description: sets the fbcondecor state for a virtual console
++argument: struct fbcon_decor_iowrapper*; data: unsigned int*
++ values: 0 = disabled, 1 = enabled.
++
++FBIOCONDECOR_GETSTATE
++description: gets the fbcondecor state for a virtual console
++argument: struct fbcon_decor_iowrapper*; data: unsigned int*
++ values: as in FBIOCONDECOR_SETSTATE
++
++Info on used structures:
++
++Definition of struct vc_decor can be found in linux/console_decor.h. It's
++heavily commented. Note that the 'theme' field should point to a string
++no longer than FBCON_DECOR_THEME_LEN. When FBIOCONDECOR_GETCFG call is
++performed, the theme field should point to a char buffer of length
++FBCON_DECOR_THEME_LEN.
++
++Definition of struct fbcon_decor_iowrapper can be found in linux/fb.h.
++The fields in this struct have the following meaning:
++
++vc:
++Virtual console number.
++
++origin:
++Specifies if the ioctl is performed as a response to a kernel request. The
++fbcondecor helper should set this field to FBCON_DECOR_IO_ORIG_KERNEL, userspace
++programs should set it to FBCON_DECOR_IO_ORIG_USER. This field is necessary to
++avoid console semaphore deadlocks.
++
++data:
++Pointer to a data structure appropriate for the performed ioctl. Type of
++the data struct is specified in the ioctls description.

++ ---help---
++ Configuring the UAC (unaligned access control) policy on a Linux
++ system usually involves setting a compile time define. If you say
++ Y here, you will be able to modify the UAC policy at runtime using
++ the /proc interface.
++
++ The UAC policy defines the action Linux should take when an
++ unaligned memory access occurs. The action can include printing a
++ warning message (NOPRINT), sending a signal to the offending
++ program to help developers debug their applications (SIGBUS), or
++ disabling the transparent fixing (NOFIX).
++
++ The sysctls will be initialized to the compile-time defined UAC
++ policy. You can change these manually, or with the sysctl(8)
++ userspace utility.
++
++ To disable the warning messages at runtime, you would use
++
++ echo 1 > /proc/sys/kernel/uac/noprint
++
++ This is pretty harmless. Say Y if you're not sure.

+WARNING
+This patch works with gcc versions 4.9+ and with kernel version 4.13+ and should
+NOT be applied when compiling on older versions of gcc due to key name changes
+of the march flags introduced with the version 4.9 release of gcc.[1]
+
+Use the older version of this patch hosted on the same github for older
+versions of gcc.
+
+FEATURES
+This patch adds additional CPU options to the Linux kernel accessible under:
+ Processor type and features --->
+ Processor family --->
+
+The expanded microarchitectures include:
+* AMD Improved K8-family
+* AMD K10-family
+* AMD Family 10h (Barcelona)
+* AMD Family 14h (Bobcat)
+* AMD Family 16h (Jaguar)
+* AMD Family 15h (Bulldozer)
+* AMD Family 15h (Piledriver)
+* AMD Family 15h (Steamroller)
+* AMD Family 15h (Excavator)
+* AMD Family 17h (Zen)
+* Intel Silvermont low-power processors
+* Intel 1st Gen Core i3/i5/i7 (Nehalem)
+* Intel 1.5 Gen Core i3/i5/i7 (Westmere)
+* Intel 2nd Gen Core i3/i5/i7 (Sandybridge)
+* Intel 3rd Gen Core i3/i5/i7 (Ivybridge)
+* Intel 4th Gen Core i3/i5/i7 (Haswell)
+* Intel 5th Gen Core i3/i5/i7 (Broadwell)
+* Intel 6th Gen Core i3/i5/i7 (Skylake)
+* Intel 6th Gen Core i7/i9 (Skylake X)
+
+It also offers to compile passing the 'native' option which, "selects the CPU
+to generate code for at compilation time by determining the processor type of
+the compiling machine. Using -march=native enables all instruction subsets
+supported by the local machine and will produce code optimized for the local
+machine under the constraints of the selected instruction set."[3]
+
+MINOR NOTES
+This patch also changes 'atom' to 'bonnell' in accordance with the gcc v4.9
+changes. Note that upstream is using the deprecated 'match=atom' flags when I
+believe it should use the newer 'march=bonnell' flag for atom processors.[2]
+
+It is not recommended to compile on Atom-CPUs with the 'native' option.[4] The
+recommendation is to use the 'atom' option instead.
+
+BENEFITS
+Small but real speed increases are measurable using a make endpoint comparing
+a generic kernel to one built with one of the respective microarchs.
+
+See the following experimental evidence supporting this statement:

++L1TF - L1 Terminal Fault
++========================
++
++L1 Terminal Fault is a hardware vulnerability which allows unprivileged
++speculative access to data which is available in the Level 1 Data Cache
++when the page table entry controlling the virtual address, which is used
++for the access, has the Present bit cleared or other reserved bits set.
++
++Affected processors
++-------------------
++
++This vulnerability affects a wide range of Intel processors. The
++vulnerability is not present on:
++
++ - Processors from AMD, Centaur and other non Intel vendors
++
++ - Older processor models, where the CPU family is < 6
++
++ - A range of Intel ATOM processors (Cedarview, Cloverview, Lincroft,
++ Penwell, Pineview, Silvermont, Airmont, Merrifield)
++
++ - The Intel XEON PHI family
++
++ - Intel processors which have the ARCH_CAP_RDCL_NO bit set in the
++ IA32_ARCH_CAPABILITIES MSR. If the bit is set the CPU is not affected
++ by the Meltdown vulnerability either. These CPUs should become
++ available by end of 2018.
++
++Whether a processor is affected or not can be read out from the L1TF
++vulnerability file in sysfs. See :ref:`l1tf_sys_info`.
++
++Related CVEs
++------------
++
++The following CVE entries are related to the L1TF vulnerability:
++
++ ============= ================= ==============================
++ CVE-2018-3615 L1 Terminal Fault SGX related aspects
++ CVE-2018-3620 L1 Terminal Fault OS, SMM related aspects
++ CVE-2018-3646 L1 Terminal Fault Virtualization related aspects
++ ============= ================= ==============================
++
++Problem
++-------
++
++If an instruction accesses a virtual address for which the relevant page
++table entry (PTE) has the Present bit cleared or other reserved bits set,
++then speculative execution ignores the invalid PTE and loads the referenced
++data if it is present in the Level 1 Data Cache, as if the page referenced
++by the address bits in the PTE was still present and accessible.
++
++While this is a purely speculative mechanism and the instruction will raise
++a page fault when it is retired eventually, the pure act of loading the
++data and making it available to other speculative instructions opens up the
++opportunity for side channel attacks to unprivileged malicious code,
++similar to the Meltdown attack.
++
++While Meltdown breaks the user space to kernel space protection, L1TF
++allows to attack any physical memory address in the system and the attack
++works across all protection domains. It allows an attack of SGX and also
++works from inside virtual machines because the speculation bypasses the
++extended page table (EPT) protection mechanism.
++
++
++Attack scenarios
++----------------
++
++1. Malicious user space
++^^^^^^^^^^^^^^^^^^^^^^^
++
++ Operating Systems store arbitrary information in the address bits of a
++ PTE which is marked non present. This allows a malicious user space
++ application to attack the physical memory to which these PTEs resolve.
++ In some cases user-space can maliciously influence the information
++ encoded in the address bits of the PTE, thus making attacks more
++ deterministic and more practical.
++
++ The Linux kernel contains a mitigation for this attack vector, PTE
++ inversion, which is permanently enabled and has no performance
++ impact. The kernel ensures that the address bits of PTEs, which are not
++ marked present, never point to cacheable physical memory space.
++
++ A system with an up to date kernel is protected against attacks from
++ malicious user space applications.
++
++2. Malicious guest in a virtual machine
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ The fact that L1TF breaks all domain protections allows malicious guest
++ OSes, which can control the PTEs directly, and malicious guest user
++ space applications, which run on an unprotected guest kernel lacking the
++ PTE inversion mitigation for L1TF, to attack physical host memory.
++
++ A special aspect of L1TF in the context of virtualization is symmetric
++ multi threading (SMT). The Intel implementation of SMT is called
++ HyperThreading. The fact that Hyperthreads on the affected processors
++ share the L1 Data Cache (L1D) is important for this. As the flaw allows
++ only to attack data which is present in L1D, a malicious guest running
++ on one Hyperthread can attack the data which is brought into the L1D by
++ the context which runs on the sibling Hyperthread of the same physical
++ core. This context can be host OS, host user space or a different guest.
++
++ If the processor does not support Extended Page Tables, the attack is
++ only possible, when the hypervisor does not sanitize the content of the
++ effective (shadow) page tables.
++
++ While solutions exist to mitigate these attack vectors fully, these
++ mitigations are not enabled by default in the Linux kernel because they
++ can affect performance significantly. The kernel provides several
++ mechanisms which can be utilized to address the problem depending on the
++ deployment scenario. The mitigations, their protection scope and impact
++ are described in the next sections.
++
++ The default mitigations and the rationale for choosing them are explained
++ at the end of this document. See :ref:`default_mitigations`.
++
++.. _l1tf_sys_info:
++
++L1TF system information
++-----------------------
++
++The Linux kernel provides a sysfs interface to enumerate the current L1TF
++status of the system: whether the system is vulnerable, and which
++mitigations are active. The relevant sysfs file is:
++
++/sys/devices/system/cpu/vulnerabilities/l1tf
++
++The possible values in this file are:
++
++ =========================== ===============================
++ 'Not affected' The processor is not vulnerable
++ 'Mitigation: PTE Inversion' The host protection is active
++ =========================== ===============================
++
++If KVM/VMX is enabled and the processor is vulnerable then the following
++information is appended to the 'Mitigation: PTE Inversion' part:
++
++ - SMT status:
++
++ ===================== ================
++ 'VMX: SMT vulnerable' SMT is enabled
++ 'VMX: SMT disabled' SMT is disabled
++ ===================== ================
++
++ - L1D Flush mode:
++
++ ================================ ====================================
++ 'L1D vulnerable' L1D flushing is disabled
++
++ 'L1D conditional cache flushes' L1D flush is conditionally enabled
++
++ 'L1D cache flushes' L1D flush is unconditionally enabled
++ ================================ ====================================
++
++The resulting grade of protection is discussed in the following sections.
++
++
++Host mitigation mechanism
++-------------------------
++
++The kernel is unconditionally protected against L1TF attacks from malicious
++user space running on the host.
++
++
++Guest mitigation mechanisms
++---------------------------
++
++.. _l1d_flush:
++
++1. L1D flush on VMENTER
++^^^^^^^^^^^^^^^^^^^^^^^
++
++ To make sure that a guest cannot attack data which is present in the L1D
++ the hypervisor flushes the L1D before entering the guest.
++
++ Flushing the L1D evicts not only the data which should not be accessed
++ by a potentially malicious guest, it also flushes the guest
++ data. Flushing the L1D has a performance impact as the processor has to
++ bring the flushed guest data back into the L1D. Depending on the
++ frequency of VMEXIT/VMENTER and the type of computations in the guest
++ performance degradation in the range of 1% to 50% has been observed. For
++ scenarios where guest VMEXIT/VMENTER are rare the performance impact is
++ minimal. Virtio and mechanisms like posted interrupts are designed to
++ confine the VMEXITs to a bare minimum, but specific configurations and
++ application scenarios might still suffer from a high VMEXIT rate.
++
++ The kernel provides two L1D flush modes:
++ - conditional ('cond')
++ - unconditional ('always')
++
++ The conditional mode avoids L1D flushing after VMEXITs which execute
++ only audited code paths before the corresponding VMENTER. These code
++ paths have been verified that they cannot expose secrets or other
++ interesting data to an attacker, but they can leak information about the
++ address space layout of the hypervisor.
++
++ Unconditional mode flushes L1D on all VMENTER invocations and provides
++ maximum protection. It has a higher overhead than the conditional
++ mode. The overhead cannot be quantified correctly as it depends on the
++ workload scenario and the resulting number of VMEXITs.
++
++ The general recommendation is to enable L1D flush on VMENTER. The kernel
++ defaults to conditional mode on affected processors.
++
++ **Note**, that L1D flush does not prevent the SMT problem because the
++ sibling thread will also bring back its data into the L1D which makes it
++ attackable again.
++
++ L1D flush can be controlled by the administrator via the kernel command
++ line and sysfs control files. See :ref:`mitigation_control_command_line`
++ and :ref:`mitigation_control_kvm`.
++
++.. _guest_confinement:
++
++2. Guest VCPU confinement to dedicated physical cores
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ To address the SMT problem, it is possible to make a guest or a group of
++ guests affine to one or more physical cores. The proper mechanism for
++ that is to utilize exclusive cpusets to ensure that no other guest or
++ host tasks can run on these cores.
++
++ If only a single guest or related guests run on sibling SMT threads on
++ the same physical core then they can only attack their own memory and
++ restricted parts of the host memory.
++
++ Host memory is attackable, when one of the sibling SMT threads runs in
++ host OS (hypervisor) context and the other in guest context. The amount
++ of valuable information from the host OS context depends on the context
++ which the host OS executes, i.e. interrupts, soft interrupts and kernel
++ threads. The amount of valuable data from these contexts cannot be
++ declared as non-interesting for an attacker without deep inspection of
++ the code.
++
++ **Note**, that assigning guests to a fixed set of physical cores affects
++ the ability of the scheduler to do load balancing and might have
++ negative effects on CPU utilization depending on the hosting
++ scenario. Disabling SMT might be a viable alternative for particular
++ scenarios.
++
++ For further information about confining guests to a single or to a group
++ of cores consult the cpusets documentation:
++
++ https://www.kernel.org/doc/Documentation/cgroup-v1/cpusets.txt
++
++.. _interrupt_isolation:
++
++3. Interrupt affinity
++^^^^^^^^^^^^^^^^^^^^^
++
++ Interrupts can be made affine to logical CPUs. This is not universally
++ true because there are types of interrupts which are truly per CPU
++ interrupts, e.g. the local timer interrupt. Aside of that multi queue
++ devices affine their interrupts to single CPUs or groups of CPUs per
++ queue without allowing the administrator to control the affinities.
++
++ Moving the interrupts, which can be affinity controlled, away from CPUs
++ which run untrusted guests, reduces the attack vector space.
++
++ Whether the interrupts with are affine to CPUs, which run untrusted
++ guests, provide interesting data for an attacker depends on the system
++ configuration and the scenarios which run on the system. While for some
++ of the interrupts it can be assumed that they won't expose interesting
++ information beyond exposing hints about the host OS memory layout, there
++ is no way to make general assumptions.
++
++ Interrupt affinity can be controlled by the administrator via the
++ /proc/irq/$NR/smp_affinity[_list] files. Limited documentation is
++ available at:
++
++ https://www.kernel.org/doc/Documentation/IRQ-affinity.txt
++
++.. _smt_control:
++
++4. SMT control
++^^^^^^^^^^^^^^
++
++ To prevent the SMT issues of L1TF it might be necessary to disable SMT
++ completely. Disabling SMT can have a significant performance impact, but
++ the impact depends on the hosting scenario and the type of workloads.
++ The impact of disabling SMT needs also to be weighted against the impact
++ of other mitigation solutions like confining guests to dedicated cores.
++
++ The kernel provides a sysfs interface to retrieve the status of SMT and
++ to control it. It also provides a kernel command line interface to
++ control SMT.
++
++ The kernel command line interface consists of the following options:
++
++ =========== ==========================================================
++ nosmt Affects the bring up of the secondary CPUs during boot. The
++ kernel tries to bring all present CPUs online during the
++ boot process. "nosmt" makes sure that from each physical
++ core only one - the so called primary (hyper) thread is
++ activated. Due to a design flaw of Intel processors related
++ to Machine Check Exceptions the non primary siblings have
++ to be brought up at least partially and are then shut down
++ again. "nosmt" can be undone via the sysfs interface.
++
++ nosmt=force Has the same effect as "nosmt" but it does not allow to
++ undo the SMT disable via the sysfs interface.
++ =========== ==========================================================
++
++ The sysfs interface provides two files:
++
++ - /sys/devices/system/cpu/smt/control
++ - /sys/devices/system/cpu/smt/active
++
++ /sys/devices/system/cpu/smt/control:
++
++ This file allows to read out the SMT control state and provides the
++ ability to disable or (re)enable SMT. The possible states are:
++
++ ============== ===================================================
++ on SMT is supported by the CPU and enabled. All
++ logical CPUs can be onlined and offlined without
++ restrictions.
++
++ off SMT is supported by the CPU and disabled. Only
++ the so called primary SMT threads can be onlined
++ and offlined without restrictions. An attempt to
++ online a non-primary sibling is rejected
++
++ forceoff Same as 'off' but the state cannot be controlled.
++ Attempts to write to the control file are rejected.
++
++ notsupported The processor does not support SMT. It's therefore
++ not affected by the SMT implications of L1TF.
++ Attempts to write to the control file are rejected.
++ ============== ===================================================
++
++ The possible states which can be written into this file to control SMT
++ state are:
++
++ - on
++ - off
++ - forceoff
++
++ /sys/devices/system/cpu/smt/active:
++
++ This file reports whether SMT is enabled and active, i.e. if on any
++ physical core two or more sibling threads are online.
++
++ SMT control is also possible at boot time via the l1tf kernel command
++ line parameter in combination with L1D flush control. See
++ :ref:`mitigation_control_command_line`.
++
++5. Disabling EPT
++^^^^^^^^^^^^^^^^
++
++ Disabling EPT for virtual machines provides full mitigation for L1TF even
++ with SMT enabled, because the effective page tables for guests are
++ managed and sanitized by the hypervisor. Though disabling EPT has a
++ significant performance impact especially when the Meltdown mitigation
++ KPTI is enabled.
++
++ EPT can be disabled in the hypervisor via the 'kvm-intel.ept' parameter.
++
++There is ongoing research and development for new mitigation mechanisms to
++address the performance impact of disabling SMT or EPT.
++
++.. _mitigation_control_command_line:
++
++Mitigation control on the kernel command line
++---------------------------------------------
++
++The kernel command line allows to control the L1TF mitigations at boot
++time with the option "l1tf=". The valid arguments for this option are:
++
++ ============ =============================================================
++ full Provides all available mitigations for the L1TF
++ vulnerability. Disables SMT and enables all mitigations in
++ the hypervisors, i.e. unconditional L1D flushing
++
++ SMT control and L1D flush control via the sysfs interface
++ is still possible after boot. Hypervisors will issue a
++ warning when the first VM is started in a potentially
++ insecure configuration, i.e. SMT enabled or L1D flush
++ disabled.
++
++ full,force Same as 'full', but disables SMT and L1D flush runtime
++ control. Implies the 'nosmt=force' command line option.
++ (i.e. sysfs control of SMT is disabled.)
++
++ flush Leaves SMT enabled and enables the default hypervisor
++ mitigation, i.e. conditional L1D flushing
++
++ SMT control and L1D flush control via the sysfs interface
++ is still possible after boot. Hypervisors will issue a
++ warning when the first VM is started in a potentially
++ insecure configuration, i.e. SMT enabled or L1D flush
++ disabled.
++
++ flush,nosmt Disables SMT and enables the default hypervisor mitigation,
++ i.e. conditional L1D flushing.
++
++ SMT control and L1D flush control via the sysfs interface
++ is still possible after boot. Hypervisors will issue a
++ warning when the first VM is started in a potentially

++ disabled.
++
++ flush,nowarn Same as 'flush', but hypervisors will not warn when a VM is
++ started in a potentially insecure configuration.
++
++ off Disables hypervisor mitigations and doesn't emit any
++ warnings.
++ ============ =============================================================
++
++The default is 'flush'. For details about L1D flushing see :ref:`l1d_flush`.
++
++
++.. _mitigation_control_kvm:
++
++Mitigation control for KVM - module parameter
++-------------------------------------------------------------
++
++The KVM hypervisor mitigation mechanism, flushing the L1D cache when
++entering a guest, can be controlled with a module parameter.
++
++The option/parameter is "kvm-intel.vmentry_l1d_flush=". It takes the
++following arguments:
++
++ ============ ==============================================================
++ always L1D cache flush on every VMENTER.
++
++ cond Flush L1D on VMENTER only when the code between VMEXIT and
++ VMENTER can leak host memory which is considered
++ interesting for an attacker. This still can leak host memory
++ which allows e.g. to determine the hosts address space layout.
++
++ never Disables the mitigation
++ ============ ==============================================================
++
++The parameter can be provided on the kernel command line, as a module
++parameter when loading the modules and at runtime modified via the sysfs
++file:
++
++/sys/module/kvm_intel/parameters/vmentry_l1d_flush
++
++The default is 'cond'. If 'l1tf=full,force' is given on the kernel command
++line, then 'always' is enforced and the kvm-intel.vmentry_l1d_flush
++module parameter is ignored and writes to the sysfs file are rejected.
++
++
++Mitigation selection guide
++--------------------------
++
++1. No virtualization in use
++^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ The system is protected by the kernel unconditionally and no further
++ action is required.
++
++2. Virtualization with trusted guests
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ If the guest comes from a trusted source and the guest OS kernel is
++ guaranteed to have the L1TF mitigations in place the system is fully
++ protected against L1TF and no further action is required.
++
++ To avoid the overhead of the default L1D flushing on VMENTER the
++ administrator can disable the flushing via the kernel command line and
++ sysfs control files. See :ref:`mitigation_control_command_line` and
++ :ref:`mitigation_control_kvm`.
++
++
++3. Virtualization with untrusted guests
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++3.1. SMT not supported or disabled
++""""""""""""""""""""""""""""""""""
++
++ If SMT is not supported by the processor or disabled in the BIOS or by
++ the kernel, it's only required to enforce L1D flushing on VMENTER.
++
++ Conditional L1D flushing is the default behaviour and can be tuned. See
++ :ref:`mitigation_control_command_line` and :ref:`mitigation_control_kvm`.
++
++3.2. EPT not supported or disabled
++""""""""""""""""""""""""""""""""""
++
++ If EPT is not supported by the processor or disabled in the hypervisor,
++ the system is fully protected. SMT can stay enabled and L1D flushing on
++ VMENTER is not required.
++
++ EPT can be disabled in the hypervisor via the 'kvm-intel.ept' parameter.
++
++3.3. SMT and EPT supported and active
++"""""""""""""""""""""""""""""""""""""
++
++ If SMT and EPT are supported and active then various degrees of
++ mitigations can be employed:
++
++ - L1D flushing on VMENTER:
++
++ L1D flushing on VMENTER is the minimal protection requirement, but it
++ is only potent in combination with other mitigation methods.
++
++ Conditional L1D flushing is the default behaviour and can be tuned. See
++ :ref:`mitigation_control_command_line` and :ref:`mitigation_control_kvm`.
++
++ - Guest confinement:
++
++ Confinement of guests to a single or a group of physical cores which
++ are not running any other processes, can reduce the attack surface
++ significantly, but interrupts, soft interrupts and kernel threads can
++ still expose valuable data to a potential attacker. See
++ :ref:`guest_confinement`.
++
++ - Interrupt isolation:
++
++ Isolating the guest CPUs from interrupts can reduce the attack surface
++ further, but still allows a malicious guest to explore a limited amount
++ of host physical memory. This can at least be used to gain knowledge
++ about the host address space layout. The interrupts which have a fixed
++ affinity to the CPUs which run the untrusted guests can depending on
++ the scenario still trigger soft interrupts and schedule kernel threads
++ which might expose valuable information. See
++ :ref:`interrupt_isolation`.
++
++The above three mitigation methods combined can provide protection to a
++certain degree, but the risk of the remaining attack surface has to be
++carefully analyzed. For full protection the following methods are
++available:
++
++ - Disabling SMT:
++
++ Disabling SMT and enforcing the L1D flushing provides the maximum
++ amount of protection. This mitigation is not depending on any of the
++ above mitigation methods.
++
++ SMT control and L1D flushing can be tuned by the command line
++ parameters 'nosmt', 'l1tf', 'kvm-intel.vmentry_l1d_flush' and at run
++ time with the matching sysfs control files. See :ref:`smt_control`,
++ :ref:`mitigation_control_command_line` and
++ :ref:`mitigation_control_kvm`.
++
++ - Disabling EPT:
++
++ Disabling EPT provides the maximum amount of protection as well. It is
++ not depending on any of the above mitigation methods. SMT can stay
++ enabled and L1D flushing is not required, but the performance impact is
++ significant.
++
++ EPT can be disabled in the hypervisor via the 'kvm-intel.ept'
++ parameter.
++
++3.4. Nested virtual machines
++""""""""""""""""""""""""""""
++
++When nested virtualization is in use, three operating systems are involved:
++the bare metal hypervisor, the nested hypervisor and the nested virtual
++machine. VMENTER operations from the nested hypervisor into the nested
++guest will always be processed by the bare metal hypervisor. If KVM is the
++bare metal hypervisor it wiil:
++
++ - Flush the L1D cache on every switch from the nested hypervisor to the
++ nested virtual machine, so that the nested hypervisor's secrets are not
++ exposed to the nested virtual machine;
++
++ - Flush the L1D cache on every switch from the nested virtual machine to
++ the nested hypervisor; this is a complex operation, and flushing the L1D
++ cache avoids that the bare metal hypervisor's secrets are exposed to the
++ nested virtual machine;
++
++ - Instruct the nested hypervisor to not perform any L1D cache flush. This
++ is an optimization to avoid double L1D flushing.
++
++
++.. _default_mitigations:
++
++Default mitigations
++-------------------
++
++ The kernel default mitigations for vulnerable processors are:
++
++ - PTE inversion to protect against malicious user space. This is done
++ unconditionally and cannot be controlled.
++
++ - L1D conditional flushing on VMENTER when EPT is enabled for
++ a guest.
++
++ The kernel does not by default enforce the disabling of SMT, which leaves
++ SMT systems vulnerable when running untrusted guests with EPT enabled.
++
++ The rationale for this choice is:
++
++ - Force disabling SMT can break existing setups, especially with
++ unattended updates.
++
++ - If regular users run untrusted guests on their machine, then L1TF is
++ just an add on to other malware which might be embedded in an untrusted
++ guest, e.g. spam-bots or attacks on the local network.
++
++ There is no technical way to prevent a user from running untrusted code
++ on their machines blindly.
++
++ - It's technically extremely unlikely and from today's knowledge even
++ impossible that L1TF can be exploited via the most popular attack
++ mechanisms like JavaScript because these mechanisms have no way to
++ control PTEs. If this would be possible and not other mitigation would
++ be possible, then the default might be different.
++
++ - The administrators of cloud and hosting setups have to carefully
++ analyze the risk for their scenarios and make the appropriate
++ mitigation choices, which might even vary across their deployed
++ machines and also result in other changes of their overall setup.
++ There is no way for the kernel to provide a sensible default for this
++ kind of scenarios.

-Subject: net: sched: Remove TCA_OPTIONS from policy
-
-Marco reported an error with hfsc:
-root@Calimero:~# tc qdisc add dev eth0 root handle 1:0 hfsc default 1
-Error: Attribute failed policy validation.
-
-Apparently a few implementations pass TCA_OPTIONS as a binary instead
-of nested attribute, so drop TCA_OPTIONS from the policy.

-Fixes: 8b4c3cdd9dd8 ("net: sched: Add policy validation for tc attributes")

+- * the variants Speck128/128, Speck128/192, Speck128/256, Speck64/96, and
+- * Speck64/128. Speck${B}/${K} denotes the variant with a block size of B bits
+- * and a key size of K bits. The Speck128 variants are believed to be the most
+- * secure variants, and they use the same block size and key sizes as AES. The
+- * Speck64 variants are less secure, but on 32-bit processors are usually
+- * faster. The remaining variants (Speck32, Speck48, and Speck96) are even less
+- * secure and/or not as well suited for implementation on either 32-bit or
+- * 64-bit processors, so are omitted.
+- *
+- * Reference: "The Simon and Speck Families of Lightweight Block Ciphers"
+- * https://eprint.iacr.org/2013/404.pdf
+- *
+- * In a correspondence, the Speck designers have also clarified that the words
+- * should be interpreted in little-endian format, and the words should be
+- * ordered such that the first word of each block is 'y' rather than 'x', and
+- * the first key word (rather than the last) becomes the first round key.

++L1TF - L1 Terminal Fault
++========================
++
++L1 Terminal Fault is a hardware vulnerability which allows unprivileged
++speculative access to data which is available in the Level 1 Data Cache
++when the page table entry controlling the virtual address, which is used
++for the access, has the Present bit cleared or other reserved bits set.
++
++Affected processors
++-------------------
++
++This vulnerability affects a wide range of Intel processors. The
++vulnerability is not present on:
++
++ - Processors from AMD, Centaur and other non Intel vendors
++
++ - Older processor models, where the CPU family is < 6
++
++ - A range of Intel ATOM processors (Cedarview, Cloverview, Lincroft,
++ Penwell, Pineview, Silvermont, Airmont, Merrifield)
++
++ - The Intel XEON PHI family
++
++ - Intel processors which have the ARCH_CAP_RDCL_NO bit set in the
++ IA32_ARCH_CAPABILITIES MSR. If the bit is set the CPU is not affected
++ by the Meltdown vulnerability either. These CPUs should become
++ available by end of 2018.
++
++Whether a processor is affected or not can be read out from the L1TF
++vulnerability file in sysfs. See :ref:`l1tf_sys_info`.
++
++Related CVEs
++------------
++
++The following CVE entries are related to the L1TF vulnerability:
++
++ ============= ================= ==============================
++ CVE-2018-3615 L1 Terminal Fault SGX related aspects
++ CVE-2018-3620 L1 Terminal Fault OS, SMM related aspects
++ CVE-2018-3646 L1 Terminal Fault Virtualization related aspects
++ ============= ================= ==============================
++
++Problem
++-------
++
++If an instruction accesses a virtual address for which the relevant page
++table entry (PTE) has the Present bit cleared or other reserved bits set,
++then speculative execution ignores the invalid PTE and loads the referenced
++data if it is present in the Level 1 Data Cache, as if the page referenced
++by the address bits in the PTE was still present and accessible.
++
++While this is a purely speculative mechanism and the instruction will raise
++a page fault when it is retired eventually, the pure act of loading the
++data and making it available to other speculative instructions opens up the
++opportunity for side channel attacks to unprivileged malicious code,
++similar to the Meltdown attack.
++
++While Meltdown breaks the user space to kernel space protection, L1TF
++allows to attack any physical memory address in the system and the attack
++works across all protection domains. It allows an attack of SGX and also
++works from inside virtual machines because the speculation bypasses the
++extended page table (EPT) protection mechanism.
++
++
++Attack scenarios
++----------------
++
++1. Malicious user space
++^^^^^^^^^^^^^^^^^^^^^^^
++
++ Operating Systems store arbitrary information in the address bits of a
++ PTE which is marked non present. This allows a malicious user space
++ application to attack the physical memory to which these PTEs resolve.
++ In some cases user-space can maliciously influence the information
++ encoded in the address bits of the PTE, thus making attacks more
++ deterministic and more practical.
++
++ The Linux kernel contains a mitigation for this attack vector, PTE
++ inversion, which is permanently enabled and has no performance
++ impact. The kernel ensures that the address bits of PTEs, which are not
++ marked present, never point to cacheable physical memory space.
++
++ A system with an up to date kernel is protected against attacks from
++ malicious user space applications.
++
++2. Malicious guest in a virtual machine
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ The fact that L1TF breaks all domain protections allows malicious guest
++ OSes, which can control the PTEs directly, and malicious guest user
++ space applications, which run on an unprotected guest kernel lacking the
++ PTE inversion mitigation for L1TF, to attack physical host memory.
++
++ A special aspect of L1TF in the context of virtualization is symmetric
++ multi threading (SMT). The Intel implementation of SMT is called
++ HyperThreading. The fact that Hyperthreads on the affected processors
++ share the L1 Data Cache (L1D) is important for this. As the flaw allows
++ only to attack data which is present in L1D, a malicious guest running
++ on one Hyperthread can attack the data which is brought into the L1D by
++ the context which runs on the sibling Hyperthread of the same physical
++ core. This context can be host OS, host user space or a different guest.
++
++ If the processor does not support Extended Page Tables, the attack is
++ only possible, when the hypervisor does not sanitize the content of the
++ effective (shadow) page tables.
++
++ While solutions exist to mitigate these attack vectors fully, these
++ mitigations are not enabled by default in the Linux kernel because they
++ can affect performance significantly. The kernel provides several
++ mechanisms which can be utilized to address the problem depending on the
++ deployment scenario. The mitigations, their protection scope and impact
++ are described in the next sections.
++
++ The default mitigations and the rationale for choosing them are explained
++ at the end of this document. See :ref:`default_mitigations`.
++
++.. _l1tf_sys_info:
++
++L1TF system information
++-----------------------
++
++The Linux kernel provides a sysfs interface to enumerate the current L1TF
++status of the system: whether the system is vulnerable, and which
++mitigations are active. The relevant sysfs file is:
++
++/sys/devices/system/cpu/vulnerabilities/l1tf
++
++The possible values in this file are:
++
++ =========================== ===============================
++ 'Not affected' The processor is not vulnerable
++ 'Mitigation: PTE Inversion' The host protection is active
++ =========================== ===============================
++
++If KVM/VMX is enabled and the processor is vulnerable then the following
++information is appended to the 'Mitigation: PTE Inversion' part:
++
++ - SMT status:
++
++ ===================== ================
++ 'VMX: SMT vulnerable' SMT is enabled
++ 'VMX: SMT disabled' SMT is disabled
++ ===================== ================
++
++ - L1D Flush mode:
++
++ ================================ ====================================
++ 'L1D vulnerable' L1D flushing is disabled
++
++ 'L1D conditional cache flushes' L1D flush is conditionally enabled
++
++ 'L1D cache flushes' L1D flush is unconditionally enabled
++ ================================ ====================================
++
++The resulting grade of protection is discussed in the following sections.
++
++
++Host mitigation mechanism
++-------------------------
++
++The kernel is unconditionally protected against L1TF attacks from malicious
++user space running on the host.
++
++
++Guest mitigation mechanisms
++---------------------------
++
++.. _l1d_flush:
++
++1. L1D flush on VMENTER
++^^^^^^^^^^^^^^^^^^^^^^^
++
++ To make sure that a guest cannot attack data which is present in the L1D
++ the hypervisor flushes the L1D before entering the guest.
++
++ Flushing the L1D evicts not only the data which should not be accessed
++ by a potentially malicious guest, it also flushes the guest
++ data. Flushing the L1D has a performance impact as the processor has to
++ bring the flushed guest data back into the L1D. Depending on the
++ frequency of VMEXIT/VMENTER and the type of computations in the guest
++ performance degradation in the range of 1% to 50% has been observed. For
++ scenarios where guest VMEXIT/VMENTER are rare the performance impact is
++ minimal. Virtio and mechanisms like posted interrupts are designed to
++ confine the VMEXITs to a bare minimum, but specific configurations and
++ application scenarios might still suffer from a high VMEXIT rate.
++
++ The kernel provides two L1D flush modes:
++ - conditional ('cond')
++ - unconditional ('always')
++
++ The conditional mode avoids L1D flushing after VMEXITs which execute
++ only audited code paths before the corresponding VMENTER. These code
++ paths have been verified that they cannot expose secrets or other
++ interesting data to an attacker, but they can leak information about the
++ address space layout of the hypervisor.
++
++ Unconditional mode flushes L1D on all VMENTER invocations and provides
++ maximum protection. It has a higher overhead than the conditional
++ mode. The overhead cannot be quantified correctly as it depends on the
++ workload scenario and the resulting number of VMEXITs.
++
++ The general recommendation is to enable L1D flush on VMENTER. The kernel
++ defaults to conditional mode on affected processors.
++
++ **Note**, that L1D flush does not prevent the SMT problem because the
++ sibling thread will also bring back its data into the L1D which makes it
++ attackable again.
++
++ L1D flush can be controlled by the administrator via the kernel command
++ line and sysfs control files. See :ref:`mitigation_control_command_line`
++ and :ref:`mitigation_control_kvm`.
++
++.. _guest_confinement:
++
++2. Guest VCPU confinement to dedicated physical cores
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ To address the SMT problem, it is possible to make a guest or a group of
++ guests affine to one or more physical cores. The proper mechanism for
++ that is to utilize exclusive cpusets to ensure that no other guest or
++ host tasks can run on these cores.
++
++ If only a single guest or related guests run on sibling SMT threads on
++ the same physical core then they can only attack their own memory and
++ restricted parts of the host memory.
++
++ Host memory is attackable, when one of the sibling SMT threads runs in
++ host OS (hypervisor) context and the other in guest context. The amount
++ of valuable information from the host OS context depends on the context
++ which the host OS executes, i.e. interrupts, soft interrupts and kernel
++ threads. The amount of valuable data from these contexts cannot be
++ declared as non-interesting for an attacker without deep inspection of
++ the code.
++
++ **Note**, that assigning guests to a fixed set of physical cores affects
++ the ability of the scheduler to do load balancing and might have
++ negative effects on CPU utilization depending on the hosting
++ scenario. Disabling SMT might be a viable alternative for particular
++ scenarios.
++
++ For further information about confining guests to a single or to a group
++ of cores consult the cpusets documentation:
++
++ https://www.kernel.org/doc/Documentation/cgroup-v1/cpusets.txt
++
++.. _interrupt_isolation:
++
++3. Interrupt affinity
++^^^^^^^^^^^^^^^^^^^^^
++
++ Interrupts can be made affine to logical CPUs. This is not universally
++ true because there are types of interrupts which are truly per CPU
++ interrupts, e.g. the local timer interrupt. Aside of that multi queue
++ devices affine their interrupts to single CPUs or groups of CPUs per
++ queue without allowing the administrator to control the affinities.
++
++ Moving the interrupts, which can be affinity controlled, away from CPUs
++ which run untrusted guests, reduces the attack vector space.
++
++ Whether the interrupts with are affine to CPUs, which run untrusted
++ guests, provide interesting data for an attacker depends on the system
++ configuration and the scenarios which run on the system. While for some
++ of the interrupts it can be assumed that they won't expose interesting
++ information beyond exposing hints about the host OS memory layout, there
++ is no way to make general assumptions.
++
++ Interrupt affinity can be controlled by the administrator via the
++ /proc/irq/$NR/smp_affinity[_list] files. Limited documentation is
++ available at:
++
++ https://www.kernel.org/doc/Documentation/IRQ-affinity.txt
++
++.. _smt_control:
++
++4. SMT control
++^^^^^^^^^^^^^^
++
++ To prevent the SMT issues of L1TF it might be necessary to disable SMT
++ completely. Disabling SMT can have a significant performance impact, but
++ the impact depends on the hosting scenario and the type of workloads.
++ The impact of disabling SMT needs also to be weighted against the impact
++ of other mitigation solutions like confining guests to dedicated cores.
++
++ The kernel provides a sysfs interface to retrieve the status of SMT and
++ to control it. It also provides a kernel command line interface to
++ control SMT.
++
++ The kernel command line interface consists of the following options:
++
++ =========== ==========================================================
++ nosmt Affects the bring up of the secondary CPUs during boot. The
++ kernel tries to bring all present CPUs online during the
++ boot process. "nosmt" makes sure that from each physical
++ core only one - the so called primary (hyper) thread is
++ activated. Due to a design flaw of Intel processors related
++ to Machine Check Exceptions the non primary siblings have
++ to be brought up at least partially and are then shut down
++ again. "nosmt" can be undone via the sysfs interface.
++
++ nosmt=force Has the same effect as "nosmt" but it does not allow to
++ undo the SMT disable via the sysfs interface.
++ =========== ==========================================================
++
++ The sysfs interface provides two files:
++
++ - /sys/devices/system/cpu/smt/control
++ - /sys/devices/system/cpu/smt/active
++
++ /sys/devices/system/cpu/smt/control:
++
++ This file allows to read out the SMT control state and provides the
++ ability to disable or (re)enable SMT. The possible states are:
++
++ ============== ===================================================
++ on SMT is supported by the CPU and enabled. All
++ logical CPUs can be onlined and offlined without
++ restrictions.
++
++ off SMT is supported by the CPU and disabled. Only
++ the so called primary SMT threads can be onlined
++ and offlined without restrictions. An attempt to
++ online a non-primary sibling is rejected
++
++ forceoff Same as 'off' but the state cannot be controlled.
++ Attempts to write to the control file are rejected.
++
++ notsupported The processor does not support SMT. It's therefore
++ not affected by the SMT implications of L1TF.
++ Attempts to write to the control file are rejected.
++ ============== ===================================================
++
++ The possible states which can be written into this file to control SMT
++ state are:
++
++ - on
++ - off
++ - forceoff
++
++ /sys/devices/system/cpu/smt/active:
++
++ This file reports whether SMT is enabled and active, i.e. if on any
++ physical core two or more sibling threads are online.
++
++ SMT control is also possible at boot time via the l1tf kernel command
++ line parameter in combination with L1D flush control. See
++ :ref:`mitigation_control_command_line`.
++
++5. Disabling EPT
++^^^^^^^^^^^^^^^^
++
++ Disabling EPT for virtual machines provides full mitigation for L1TF even
++ with SMT enabled, because the effective page tables for guests are
++ managed and sanitized by the hypervisor. Though disabling EPT has a
++ significant performance impact especially when the Meltdown mitigation
++ KPTI is enabled.
++
++ EPT can be disabled in the hypervisor via the 'kvm-intel.ept' parameter.
++
++There is ongoing research and development for new mitigation mechanisms to
++address the performance impact of disabling SMT or EPT.
++
++.. _mitigation_control_command_line:
++
++Mitigation control on the kernel command line
++---------------------------------------------
++
++The kernel command line allows to control the L1TF mitigations at boot
++time with the option "l1tf=". The valid arguments for this option are:
++
++ ============ =============================================================
++ full Provides all available mitigations for the L1TF
++ vulnerability. Disables SMT and enables all mitigations in
++ the hypervisors, i.e. unconditional L1D flushing
++
++ SMT control and L1D flush control via the sysfs interface
++ is still possible after boot. Hypervisors will issue a
++ warning when the first VM is started in a potentially
++ insecure configuration, i.e. SMT enabled or L1D flush
++ disabled.
++
++ full,force Same as 'full', but disables SMT and L1D flush runtime
++ control. Implies the 'nosmt=force' command line option.
++ (i.e. sysfs control of SMT is disabled.)
++
++ flush Leaves SMT enabled and enables the default hypervisor
++ mitigation, i.e. conditional L1D flushing
++
++ SMT control and L1D flush control via the sysfs interface
++ is still possible after boot. Hypervisors will issue a
++ warning when the first VM is started in a potentially
++ insecure configuration, i.e. SMT enabled or L1D flush
++ disabled.
++
++ flush,nosmt Disables SMT and enables the default hypervisor mitigation,
++ i.e. conditional L1D flushing.
++
++ SMT control and L1D flush control via the sysfs interface
++ is still possible after boot. Hypervisors will issue a
++ warning when the first VM is started in a potentially
++ insecure configuration, i.e. SMT enabled or L1D flush
++ disabled.
++
++ flush,nowarn Same as 'flush', but hypervisors will not warn when a VM is
++ started in a potentially insecure configuration.
++
++ off Disables hypervisor mitigations and doesn't emit any
++ warnings.
++ ============ =============================================================
++
++The default is 'flush'. For details about L1D flushing see :ref:`l1d_flush`.
++
++
++.. _mitigation_control_kvm:
++
++Mitigation control for KVM - module parameter
++-------------------------------------------------------------
++
++The KVM hypervisor mitigation mechanism, flushing the L1D cache when
++entering a guest, can be controlled with a module parameter.
++
++The option/parameter is "kvm-intel.vmentry_l1d_flush=". It takes the
++following arguments:
++
++ ============ ==============================================================
++ always L1D cache flush on every VMENTER.
++
++ cond Flush L1D on VMENTER only when the code between VMEXIT and
++ VMENTER can leak host memory which is considered
++ interesting for an attacker. This still can leak host memory
++ which allows e.g. to determine the hosts address space layout.
++
++ never Disables the mitigation
++ ============ ==============================================================
++
++The parameter can be provided on the kernel command line, as a module
++parameter when loading the modules and at runtime modified via the sysfs
++file:
++
++/sys/module/kvm_intel/parameters/vmentry_l1d_flush
++
++The default is 'cond'. If 'l1tf=full,force' is given on the kernel command
++line, then 'always' is enforced and the kvm-intel.vmentry_l1d_flush
++module parameter is ignored and writes to the sysfs file are rejected.
++
++
++Mitigation selection guide
++--------------------------
++
++1. No virtualization in use
++^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ The system is protected by the kernel unconditionally and no further
++ action is required.
++
++2. Virtualization with trusted guests
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ If the guest comes from a trusted source and the guest OS kernel is
++ guaranteed to have the L1TF mitigations in place the system is fully
++ protected against L1TF and no further action is required.
++
++ To avoid the overhead of the default L1D flushing on VMENTER the
++ administrator can disable the flushing via the kernel command line and
++ sysfs control files. See :ref:`mitigation_control_command_line` and
++ :ref:`mitigation_control_kvm`.
++
++
++3. Virtualization with untrusted guests
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++3.1. SMT not supported or disabled
++""""""""""""""""""""""""""""""""""
++
++ If SMT is not supported by the processor or disabled in the BIOS or by
++ the kernel, it's only required to enforce L1D flushing on VMENTER.
++
++ Conditional L1D flushing is the default behaviour and can be tuned. See
++ :ref:`mitigation_control_command_line` and :ref:`mitigation_control_kvm`.
++
++3.2. EPT not supported or disabled
++""""""""""""""""""""""""""""""""""
++
++ If EPT is not supported by the processor or disabled in the hypervisor,
++ the system is fully protected. SMT can stay enabled and L1D flushing on
++ VMENTER is not required.
++
++ EPT can be disabled in the hypervisor via the 'kvm-intel.ept' parameter.
++
++3.3. SMT and EPT supported and active
++"""""""""""""""""""""""""""""""""""""
++
++ If SMT and EPT are supported and active then various degrees of
++ mitigations can be employed:
++
++ - L1D flushing on VMENTER:
++
++ L1D flushing on VMENTER is the minimal protection requirement, but it
++ is only potent in combination with other mitigation methods.
++
++ Conditional L1D flushing is the default behaviour and can be tuned. See
++ :ref:`mitigation_control_command_line` and :ref:`mitigation_control_kvm`.
++
++ - Guest confinement:
++
++ Confinement of guests to a single or a group of physical cores which
++ are not running any other processes, can reduce the attack surface
++ significantly, but interrupts, soft interrupts and kernel threads can
++ still expose valuable data to a potential attacker. See
++ :ref:`guest_confinement`.
++
++ - Interrupt isolation:
++
++ Isolating the guest CPUs from interrupts can reduce the attack surface
++ further, but still allows a malicious guest to explore a limited amount
++ of host physical memory. This can at least be used to gain knowledge
++ about the host address space layout. The interrupts which have a fixed
++ affinity to the CPUs which run the untrusted guests can depending on
++ the scenario still trigger soft interrupts and schedule kernel threads
++ which might expose valuable information. See
++ :ref:`interrupt_isolation`.
++
++The above three mitigation methods combined can provide protection to a
++certain degree, but the risk of the remaining attack surface has to be
++carefully analyzed. For full protection the following methods are
++available:
++
++ - Disabling SMT:
++
++ Disabling SMT and enforcing the L1D flushing provides the maximum
++ amount of protection. This mitigation is not depending on any of the
++ above mitigation methods.
++
++ SMT control and L1D flushing can be tuned by the command line
++ parameters 'nosmt', 'l1tf', 'kvm-intel.vmentry_l1d_flush' and at run
++ time with the matching sysfs control files. See :ref:`smt_control`,
++ :ref:`mitigation_control_command_line` and
++ :ref:`mitigation_control_kvm`.
++
++ - Disabling EPT:
++
++ Disabling EPT provides the maximum amount of protection as well. It is
++ not depending on any of the above mitigation methods. SMT can stay
++ enabled and L1D flushing is not required, but the performance impact is
++ significant.
++
++ EPT can be disabled in the hypervisor via the 'kvm-intel.ept'
++ parameter.
++
++3.4. Nested virtual machines
++""""""""""""""""""""""""""""
++
++When nested virtualization is in use, three operating systems are involved:
++the bare metal hypervisor, the nested hypervisor and the nested virtual
++machine. VMENTER operations from the nested hypervisor into the nested
++guest will always be processed by the bare metal hypervisor. If KVM is the
++bare metal hypervisor it wiil:
++
++ - Flush the L1D cache on every switch from the nested hypervisor to the
++ nested virtual machine, so that the nested hypervisor's secrets are not
++ exposed to the nested virtual machine;
++
++ - Flush the L1D cache on every switch from the nested virtual machine to
++ the nested hypervisor; this is a complex operation, and flushing the L1D
++ cache avoids that the bare metal hypervisor's secrets are exposed to the
++ nested virtual machine;
++
++ - Instruct the nested hypervisor to not perform any L1D cache flush. This
++ is an optimization to avoid double L1D flushing.
++
++
++.. _default_mitigations:
++
++Default mitigations
++-------------------
++
++ The kernel default mitigations for vulnerable processors are:
++
++ - PTE inversion to protect against malicious user space. This is done
++ unconditionally and cannot be controlled.
++
++ - L1D conditional flushing on VMENTER when EPT is enabled for
++ a guest.
++
++ The kernel does not by default enforce the disabling of SMT, which leaves
++ SMT systems vulnerable when running untrusted guests with EPT enabled.
++
++ The rationale for this choice is:
++
++ - Force disabling SMT can break existing setups, especially with
++ unattended updates.
++
++ - If regular users run untrusted guests on their machine, then L1TF is
++ just an add on to other malware which might be embedded in an untrusted
++ guest, e.g. spam-bots or attacks on the local network.
++
++ There is no technical way to prevent a user from running untrusted code
++ on their machines blindly.
++
++ - It's technically extremely unlikely and from today's knowledge even
++ impossible that L1TF can be exploited via the most popular attack
++ mechanisms like JavaScript because these mechanisms have no way to
++ control PTEs. If this would be possible and not other mitigation would
++ be possible, then the default might be different.
++
++ - The administrators of cloud and hosting setups have to carefully
++ analyze the risk for their scenarios and make the appropriate
++ mitigation choices, which might even vary across their deployed
++ machines and also result in other changes of their overall setup.
++ There is no way for the kernel to provide a sensible default for this
++ kind of scenarios.

+-Similarly, Speck128/256 support was only added for older or low-end

+-NEON instructions but not the Cryptography Extensions -- and for which
+-it would not otherwise be feasible to use encryption at all. It is
+-not recommended to use Speck on CPUs that have AES instructions.

+- * Speck: a lightweight block cipher

+- *
+- * Speck has 10 variants, including 5 block sizes. For now we only implement
+- * the variants Speck128/128, Speck128/192, Speck128/256, Speck64/96, and
+- * Speck64/128. Speck${B}/${K} denotes the variant with a block size of B bits
+- * and a key size of K bits. The Speck128 variants are believed to be the most
+- * secure variants, and they use the same block size and key sizes as AES. The
+- * Speck64 variants are less secure, but on 32-bit processors are usually
+- * faster. The remaining variants (Speck32, Speck48, and Speck96) are even less
+- * secure and/or not as well suited for implementation on either 32-bit or
+- * 64-bit processors, so are omitted.
+- *
+- * Reference: "The Simon and Speck Families of Lightweight Block Ciphers"
+- * https://eprint.iacr.org/2013/404.pdf
+- *
+- * In a correspondence, the Speck designers have also clarified that the words
+- * should be interpreted in little-endian format, and the words should be
+- * ordered such that the first word of each block is 'y' rather than 'x', and
+- * the first key word (rather than the last) becomes the first round key.

+
+Fixes: 8b4c3cdd9dd8 ("net: sched: Add policy validation for tc attributes")

++L1TF - L1 Terminal Fault
++========================
++
++L1 Terminal Fault is a hardware vulnerability which allows unprivileged
++speculative access to data which is available in the Level 1 Data Cache
++when the page table entry controlling the virtual address, which is used
++for the access, has the Present bit cleared or other reserved bits set.
++
++Affected processors
++-------------------
++
++This vulnerability affects a wide range of Intel processors. The
++vulnerability is not present on:
++
++ - Processors from AMD, Centaur and other non Intel vendors
++
++ - Older processor models, where the CPU family is < 6
++
++ - A range of Intel ATOM processors (Cedarview, Cloverview, Lincroft,
++ Penwell, Pineview, Silvermont, Airmont, Merrifield)
++
++ - The Intel XEON PHI family
++
++ - Intel processors which have the ARCH_CAP_RDCL_NO bit set in the
++ IA32_ARCH_CAPABILITIES MSR. If the bit is set the CPU is not affected
++ by the Meltdown vulnerability either. These CPUs should become
++ available by end of 2018.
++
++Whether a processor is affected or not can be read out from the L1TF
++vulnerability file in sysfs. See :ref:`l1tf_sys_info`.
++
++Related CVEs
++------------
++
++The following CVE entries are related to the L1TF vulnerability:
++
++ ============= ================= ==============================
++ CVE-2018-3615 L1 Terminal Fault SGX related aspects
++ CVE-2018-3620 L1 Terminal Fault OS, SMM related aspects
++ CVE-2018-3646 L1 Terminal Fault Virtualization related aspects
++ ============= ================= ==============================
++
++Problem
++-------
++
++If an instruction accesses a virtual address for which the relevant page
++table entry (PTE) has the Present bit cleared or other reserved bits set,
++then speculative execution ignores the invalid PTE and loads the referenced
++data if it is present in the Level 1 Data Cache, as if the page referenced
++by the address bits in the PTE was still present and accessible.
++
++While this is a purely speculative mechanism and the instruction will raise
++a page fault when it is retired eventually, the pure act of loading the
++data and making it available to other speculative instructions opens up the
++opportunity for side channel attacks to unprivileged malicious code,
++similar to the Meltdown attack.
++
++While Meltdown breaks the user space to kernel space protection, L1TF
++allows to attack any physical memory address in the system and the attack
++works across all protection domains. It allows an attack of SGX and also
++works from inside virtual machines because the speculation bypasses the
++extended page table (EPT) protection mechanism.
++
++
++Attack scenarios
++----------------
++
++1. Malicious user space
++^^^^^^^^^^^^^^^^^^^^^^^
++
++ Operating Systems store arbitrary information in the address bits of a
++ PTE which is marked non present. This allows a malicious user space
++ application to attack the physical memory to which these PTEs resolve.
++ In some cases user-space can maliciously influence the information
++ encoded in the address bits of the PTE, thus making attacks more
++ deterministic and more practical.
++
++ The Linux kernel contains a mitigation for this attack vector, PTE
++ inversion, which is permanently enabled and has no performance
++ impact. The kernel ensures that the address bits of PTEs, which are not
++ marked present, never point to cacheable physical memory space.
++
++ A system with an up to date kernel is protected against attacks from
++ malicious user space applications.
++
++2. Malicious guest in a virtual machine
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ The fact that L1TF breaks all domain protections allows malicious guest
++ OSes, which can control the PTEs directly, and malicious guest user
++ space applications, which run on an unprotected guest kernel lacking the
++ PTE inversion mitigation for L1TF, to attack physical host memory.
++
++ A special aspect of L1TF in the context of virtualization is symmetric
++ multi threading (SMT). The Intel implementation of SMT is called
++ HyperThreading. The fact that Hyperthreads on the affected processors
++ share the L1 Data Cache (L1D) is important for this. As the flaw allows
++ only to attack data which is present in L1D, a malicious guest running
++ on one Hyperthread can attack the data which is brought into the L1D by
++ the context which runs on the sibling Hyperthread of the same physical
++ core. This context can be host OS, host user space or a different guest.
++
++ If the processor does not support Extended Page Tables, the attack is
++ only possible, when the hypervisor does not sanitize the content of the
++ effective (shadow) page tables.
++
++ While solutions exist to mitigate these attack vectors fully, these
++ mitigations are not enabled by default in the Linux kernel because they
++ can affect performance significantly. The kernel provides several
++ mechanisms which can be utilized to address the problem depending on the
++ deployment scenario. The mitigations, their protection scope and impact
++ are described in the next sections.
++
++ The default mitigations and the rationale for choosing them are explained
++ at the end of this document. See :ref:`default_mitigations`.
++
++.. _l1tf_sys_info:
++
++L1TF system information
++-----------------------
++
++The Linux kernel provides a sysfs interface to enumerate the current L1TF
++status of the system: whether the system is vulnerable, and which
++mitigations are active. The relevant sysfs file is:
++
++/sys/devices/system/cpu/vulnerabilities/l1tf
++
++The possible values in this file are:
++
++ =========================== ===============================
++ 'Not affected' The processor is not vulnerable
++ 'Mitigation: PTE Inversion' The host protection is active
++ =========================== ===============================
++
++If KVM/VMX is enabled and the processor is vulnerable then the following
++information is appended to the 'Mitigation: PTE Inversion' part:
++
++ - SMT status:
++
++ ===================== ================
++ 'VMX: SMT vulnerable' SMT is enabled
++ 'VMX: SMT disabled' SMT is disabled
++ ===================== ================
++
++ - L1D Flush mode:
++
++ ================================ ====================================
++ 'L1D vulnerable' L1D flushing is disabled
++
++ 'L1D conditional cache flushes' L1D flush is conditionally enabled
++
++ 'L1D cache flushes' L1D flush is unconditionally enabled
++ ================================ ====================================
++
++The resulting grade of protection is discussed in the following sections.
++
++
++Host mitigation mechanism
++-------------------------
++
++The kernel is unconditionally protected against L1TF attacks from malicious
++user space running on the host.
++
++
++Guest mitigation mechanisms
++---------------------------
++
++.. _l1d_flush:
++
++1. L1D flush on VMENTER
++^^^^^^^^^^^^^^^^^^^^^^^
++
++ To make sure that a guest cannot attack data which is present in the L1D
++ the hypervisor flushes the L1D before entering the guest.
++
++ Flushing the L1D evicts not only the data which should not be accessed
++ by a potentially malicious guest, it also flushes the guest
++ data. Flushing the L1D has a performance impact as the processor has to
++ bring the flushed guest data back into the L1D. Depending on the
++ frequency of VMEXIT/VMENTER and the type of computations in the guest
++ performance degradation in the range of 1% to 50% has been observed. For
++ scenarios where guest VMEXIT/VMENTER are rare the performance impact is
++ minimal. Virtio and mechanisms like posted interrupts are designed to
++ confine the VMEXITs to a bare minimum, but specific configurations and
++ application scenarios might still suffer from a high VMEXIT rate.
++
++ The kernel provides two L1D flush modes:
++ - conditional ('cond')
++ - unconditional ('always')
++
++ The conditional mode avoids L1D flushing after VMEXITs which execute
++ only audited code paths before the corresponding VMENTER. These code
++ paths have been verified that they cannot expose secrets or other
++ interesting data to an attacker, but they can leak information about the
++ address space layout of the hypervisor.
++
++ Unconditional mode flushes L1D on all VMENTER invocations and provides
++ maximum protection. It has a higher overhead than the conditional
++ mode. The overhead cannot be quantified correctly as it depends on the
++ workload scenario and the resulting number of VMEXITs.
++
++ The general recommendation is to enable L1D flush on VMENTER. The kernel
++ defaults to conditional mode on affected processors.
++
++ **Note**, that L1D flush does not prevent the SMT problem because the
++ sibling thread will also bring back its data into the L1D which makes it
++ attackable again.
++
++ L1D flush can be controlled by the administrator via the kernel command
++ line and sysfs control files. See :ref:`mitigation_control_command_line`
++ and :ref:`mitigation_control_kvm`.
++
++.. _guest_confinement:
++
++2. Guest VCPU confinement to dedicated physical cores
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ To address the SMT problem, it is possible to make a guest or a group of
++ guests affine to one or more physical cores. The proper mechanism for
++ that is to utilize exclusive cpusets to ensure that no other guest or
++ host tasks can run on these cores.
++
++ If only a single guest or related guests run on sibling SMT threads on
++ the same physical core then they can only attack their own memory and
++ restricted parts of the host memory.
++
++ Host memory is attackable, when one of the sibling SMT threads runs in
++ host OS (hypervisor) context and the other in guest context. The amount
++ of valuable information from the host OS context depends on the context
++ which the host OS executes, i.e. interrupts, soft interrupts and kernel
++ threads. The amount of valuable data from these contexts cannot be
++ declared as non-interesting for an attacker without deep inspection of
++ the code.
++
++ **Note**, that assigning guests to a fixed set of physical cores affects
++ the ability of the scheduler to do load balancing and might have
++ negative effects on CPU utilization depending on the hosting
++ scenario. Disabling SMT might be a viable alternative for particular
++ scenarios.
++
++ For further information about confining guests to a single or to a group
++ of cores consult the cpusets documentation:
++
++ https://www.kernel.org/doc/Documentation/cgroup-v1/cpusets.txt
++
++.. _interrupt_isolation:
++
++3. Interrupt affinity
++^^^^^^^^^^^^^^^^^^^^^
++
++ Interrupts can be made affine to logical CPUs. This is not universally
++ true because there are types of interrupts which are truly per CPU
++ interrupts, e.g. the local timer interrupt. Aside of that multi queue
++ devices affine their interrupts to single CPUs or groups of CPUs per
++ queue without allowing the administrator to control the affinities.
++
++ Moving the interrupts, which can be affinity controlled, away from CPUs
++ which run untrusted guests, reduces the attack vector space.
++
++ Whether the interrupts with are affine to CPUs, which run untrusted
++ guests, provide interesting data for an attacker depends on the system
++ configuration and the scenarios which run on the system. While for some
++ of the interrupts it can be assumed that they won't expose interesting
++ information beyond exposing hints about the host OS memory layout, there
++ is no way to make general assumptions.
++
++ Interrupt affinity can be controlled by the administrator via the
++ /proc/irq/$NR/smp_affinity[_list] files. Limited documentation is
++ available at:
++
++ https://www.kernel.org/doc/Documentation/IRQ-affinity.txt
++
++.. _smt_control:
++
++4. SMT control
++^^^^^^^^^^^^^^
++
++ To prevent the SMT issues of L1TF it might be necessary to disable SMT
++ completely. Disabling SMT can have a significant performance impact, but
++ the impact depends on the hosting scenario and the type of workloads.
++ The impact of disabling SMT needs also to be weighted against the impact
++ of other mitigation solutions like confining guests to dedicated cores.
++
++ The kernel provides a sysfs interface to retrieve the status of SMT and
++ to control it. It also provides a kernel command line interface to
++ control SMT.
++
++ The kernel command line interface consists of the following options:
++
++ =========== ==========================================================
++ nosmt Affects the bring up of the secondary CPUs during boot. The
++ kernel tries to bring all present CPUs online during the
++ boot process. "nosmt" makes sure that from each physical
++ core only one - the so called primary (hyper) thread is
++ activated. Due to a design flaw of Intel processors related
++ to Machine Check Exceptions the non primary siblings have
++ to be brought up at least partially and are then shut down
++ again. "nosmt" can be undone via the sysfs interface.
++
++ nosmt=force Has the same effect as "nosmt" but it does not allow to
++ undo the SMT disable via the sysfs interface.
++ =========== ==========================================================
++
++ The sysfs interface provides two files:
++
++ - /sys/devices/system/cpu/smt/control
++ - /sys/devices/system/cpu/smt/active
++
++ /sys/devices/system/cpu/smt/control:
++
++ This file allows to read out the SMT control state and provides the
++ ability to disable or (re)enable SMT. The possible states are:
++
++ ============== ===================================================
++ on SMT is supported by the CPU and enabled. All
++ logical CPUs can be onlined and offlined without
++ restrictions.
++
++ off SMT is supported by the CPU and disabled. Only
++ the so called primary SMT threads can be onlined
++ and offlined without restrictions. An attempt to
++ online a non-primary sibling is rejected
++
++ forceoff Same as 'off' but the state cannot be controlled.
++ Attempts to write to the control file are rejected.
++
++ notsupported The processor does not support SMT. It's therefore
++ not affected by the SMT implications of L1TF.
++ Attempts to write to the control file are rejected.
++ ============== ===================================================
++
++ The possible states which can be written into this file to control SMT
++ state are:
++
++ - on
++ - off
++ - forceoff
++
++ /sys/devices/system/cpu/smt/active:
++
++ This file reports whether SMT is enabled and active, i.e. if on any
++ physical core two or more sibling threads are online.
++
++ SMT control is also possible at boot time via the l1tf kernel command
++ line parameter in combination with L1D flush control. See
++ :ref:`mitigation_control_command_line`.
++
++5. Disabling EPT
++^^^^^^^^^^^^^^^^
++
++ Disabling EPT for virtual machines provides full mitigation for L1TF even
++ with SMT enabled, because the effective page tables for guests are
++ managed and sanitized by the hypervisor. Though disabling EPT has a
++ significant performance impact especially when the Meltdown mitigation
++ KPTI is enabled.
++
++ EPT can be disabled in the hypervisor via the 'kvm-intel.ept' parameter.
++
++There is ongoing research and development for new mitigation mechanisms to
++address the performance impact of disabling SMT or EPT.
++
++.. _mitigation_control_command_line:
++
++Mitigation control on the kernel command line
++---------------------------------------------
++
++The kernel command line allows to control the L1TF mitigations at boot
++time with the option "l1tf=". The valid arguments for this option are:
++
++ ============ =============================================================
++ full Provides all available mitigations for the L1TF
++ vulnerability. Disables SMT and enables all mitigations in
++ the hypervisors, i.e. unconditional L1D flushing
++
++ SMT control and L1D flush control via the sysfs interface
++ is still possible after boot. Hypervisors will issue a
++ warning when the first VM is started in a potentially
++ insecure configuration, i.e. SMT enabled or L1D flush
++ disabled.
++
++ full,force Same as 'full', but disables SMT and L1D flush runtime
++ control. Implies the 'nosmt=force' command line option.
++ (i.e. sysfs control of SMT is disabled.)
++
++ flush Leaves SMT enabled and enables the default hypervisor
++ mitigation, i.e. conditional L1D flushing
++
++ SMT control and L1D flush control via the sysfs interface
++ is still possible after boot. Hypervisors will issue a
++ warning when the first VM is started in a potentially
++ insecure configuration, i.e. SMT enabled or L1D flush
++ disabled.
++
++ flush,nosmt Disables SMT and enables the default hypervisor mitigation,
++ i.e. conditional L1D flushing.
++
++ SMT control and L1D flush control via the sysfs interface
++ is still possible after boot. Hypervisors will issue a
++ warning when the first VM is started in a potentially
++ insecure configuration, i.e. SMT enabled or L1D flush
++ disabled.
++
++ flush,nowarn Same as 'flush', but hypervisors will not warn when a VM is
++ started in a potentially insecure configuration.
++
++ off Disables hypervisor mitigations and doesn't emit any
++ warnings.
++ ============ =============================================================
++
++The default is 'flush'. For details about L1D flushing see :ref:`l1d_flush`.
++
++
++.. _mitigation_control_kvm:
++
++Mitigation control for KVM - module parameter
++-------------------------------------------------------------
++
++The KVM hypervisor mitigation mechanism, flushing the L1D cache when
++entering a guest, can be controlled with a module parameter.
++
++The option/parameter is "kvm-intel.vmentry_l1d_flush=". It takes the
++following arguments:
++
++ ============ ==============================================================
++ always L1D cache flush on every VMENTER.
++
++ cond Flush L1D on VMENTER only when the code between VMEXIT and
++ VMENTER can leak host memory which is considered
++ interesting for an attacker. This still can leak host memory
++ which allows e.g. to determine the hosts address space layout.
++
++ never Disables the mitigation
++ ============ ==============================================================
++
++The parameter can be provided on the kernel command line, as a module
++parameter when loading the modules and at runtime modified via the sysfs
++file:
++
++/sys/module/kvm_intel/parameters/vmentry_l1d_flush
++
++The default is 'cond'. If 'l1tf=full,force' is given on the kernel command
++line, then 'always' is enforced and the kvm-intel.vmentry_l1d_flush
++module parameter is ignored and writes to the sysfs file are rejected.
++
++
++Mitigation selection guide
++--------------------------
++
++1. No virtualization in use
++^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ The system is protected by the kernel unconditionally and no further
++ action is required.
++
++2. Virtualization with trusted guests
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ If the guest comes from a trusted source and the guest OS kernel is
++ guaranteed to have the L1TF mitigations in place the system is fully
++ protected against L1TF and no further action is required.
++
++ To avoid the overhead of the default L1D flushing on VMENTER the
++ administrator can disable the flushing via the kernel command line and
++ sysfs control files. See :ref:`mitigation_control_command_line` and
++ :ref:`mitigation_control_kvm`.
++
++
++3. Virtualization with untrusted guests
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++3.1. SMT not supported or disabled
++""""""""""""""""""""""""""""""""""
++
++ If SMT is not supported by the processor or disabled in the BIOS or by
++ the kernel, it's only required to enforce L1D flushing on VMENTER.
++
++ Conditional L1D flushing is the default behaviour and can be tuned. See
++ :ref:`mitigation_control_command_line` and :ref:`mitigation_control_kvm`.
++
++3.2. EPT not supported or disabled
++""""""""""""""""""""""""""""""""""
++
++ If EPT is not supported by the processor or disabled in the hypervisor,
++ the system is fully protected. SMT can stay enabled and L1D flushing on
++ VMENTER is not required.
++
++ EPT can be disabled in the hypervisor via the 'kvm-intel.ept' parameter.
++
++3.3. SMT and EPT supported and active
++"""""""""""""""""""""""""""""""""""""
++
++ If SMT and EPT are supported and active then various degrees of
++ mitigations can be employed:
++
++ - L1D flushing on VMENTER:
++
++ L1D flushing on VMENTER is the minimal protection requirement, but it
++ is only potent in combination with other mitigation methods.
++
++ Conditional L1D flushing is the default behaviour and can be tuned. See
++ :ref:`mitigation_control_command_line` and :ref:`mitigation_control_kvm`.
++
++ - Guest confinement:
++
++ Confinement of guests to a single or a group of physical cores which
++ are not running any other processes, can reduce the attack surface
++ significantly, but interrupts, soft interrupts and kernel threads can
++ still expose valuable data to a potential attacker. See
++ :ref:`guest_confinement`.
++
++ - Interrupt isolation:
++
++ Isolating the guest CPUs from interrupts can reduce the attack surface
++ further, but still allows a malicious guest to explore a limited amount
++ of host physical memory. This can at least be used to gain knowledge
++ about the host address space layout. The interrupts which have a fixed
++ affinity to the CPUs which run the untrusted guests can depending on
++ the scenario still trigger soft interrupts and schedule kernel threads
++ which might expose valuable information. See
++ :ref:`interrupt_isolation`.
++
++The above three mitigation methods combined can provide protection to a
++certain degree, but the risk of the remaining attack surface has to be
++carefully analyzed. For full protection the following methods are
++available:
++
++ - Disabling SMT:
++
++ Disabling SMT and enforcing the L1D flushing provides the maximum
++ amount of protection. This mitigation is not depending on any of the
++ above mitigation methods.
++
++ SMT control and L1D flushing can be tuned by the command line
++ parameters 'nosmt', 'l1tf', 'kvm-intel.vmentry_l1d_flush' and at run
++ time with the matching sysfs control files. See :ref:`smt_control`,
++ :ref:`mitigation_control_command_line` and
++ :ref:`mitigation_control_kvm`.
++
++ - Disabling EPT:
++
++ Disabling EPT provides the maximum amount of protection as well. It is
++ not depending on any of the above mitigation methods. SMT can stay
++ enabled and L1D flushing is not required, but the performance impact is
++ significant.
++
++ EPT can be disabled in the hypervisor via the 'kvm-intel.ept'
++ parameter.
++
++3.4. Nested virtual machines
++""""""""""""""""""""""""""""
++
++When nested virtualization is in use, three operating systems are involved:
++the bare metal hypervisor, the nested hypervisor and the nested virtual
++machine. VMENTER operations from the nested hypervisor into the nested
++guest will always be processed by the bare metal hypervisor. If KVM is the
++bare metal hypervisor it wiil:
++
++ - Flush the L1D cache on every switch from the nested hypervisor to the
++ nested virtual machine, so that the nested hypervisor's secrets are not
++ exposed to the nested virtual machine;
++
++ - Flush the L1D cache on every switch from the nested virtual machine to
++ the nested hypervisor; this is a complex operation, and flushing the L1D
++ cache avoids that the bare metal hypervisor's secrets are exposed to the
++ nested virtual machine;
++
++ - Instruct the nested hypervisor to not perform any L1D cache flush. This
++ is an optimization to avoid double L1D flushing.
++
++
++.. _default_mitigations:
++
++Default mitigations
++-------------------
++
++ The kernel default mitigations for vulnerable processors are:
++
++ - PTE inversion to protect against malicious user space. This is done
++ unconditionally and cannot be controlled.
++
++ - L1D conditional flushing on VMENTER when EPT is enabled for
++ a guest.
++
++ The kernel does not by default enforce the disabling of SMT, which leaves
++ SMT systems vulnerable when running untrusted guests with EPT enabled.
++
++ The rationale for this choice is:
++
++ - Force disabling SMT can break existing setups, especially with
++ unattended updates.
++
++ - If regular users run untrusted guests on their machine, then L1TF is
++ just an add on to other malware which might be embedded in an untrusted
++ guest, e.g. spam-bots or attacks on the local network.
++
++ There is no technical way to prevent a user from running untrusted code
++ on their machines blindly.
++
++ - It's technically extremely unlikely and from today's knowledge even
++ impossible that L1TF can be exploited via the most popular attack
++ mechanisms like JavaScript because these mechanisms have no way to
++ control PTEs. If this would be possible and not other mitigation would
++ be possible, then the default might be different.
++
++ - The administrators of cloud and hosting setups have to carefully
++ analyze the risk for their scenarios and make the appropriate
++ mitigation choices, which might even vary across their deployed
++ machines and also result in other changes of their overall setup.
++ There is no way for the kernel to provide a sensible default for this
++ kind of scenarios.
