+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.
