+WARNING
+This patch works with gcc versions 9.1+ 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)
+* AMD Family 17h (Zen 2)
+* Intel Silvermont low-power processors
+* Intel Goldmont low-power processors (Apollo Lake and Denverton)
+* Intel Goldmont Plus low-power processors (Gemini Lake)
+* 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)
+* Intel 8th Gen Core i3/i5/i7 (Cannon Lake)
+* Intel 10th Gen Core i7/i9 (Ice Lake)
+* Intel Xeon (Cascade Lake)
+
+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.
+

++ * We are an i2c-adapter which itself is part of an i2c-client. This means that

++ * i2c-adapter and once to take our own bus_lock. Lockdep does not like this
++ * nested locking, to make lockdep happy in the case of busses with muxes, the
++ * i2c-core's i2c_adapter_lock_bus function calls:
++ * rt_mutex_lock_nested(&adapter->bus_lock, i2c_adapter_depth(adapter));
++ *
++ * But i2c_adapter_depth only works when the direct parent of the adapter is
++ * another adapter, as it is only meant for muxes. In our case there is an
++ * i2c-client and MFD instantiated platform_device in the parent->child chain
++ * between the 2 devices.
++ *
++ * So we override the default i2c_lock_operations and pass a hardcoded
++ * depth of 1 to rt_mutex_lock_nested, to make lockdep happy.
++ *
++ * Note that if there were to be a mux attached to our adapter, this would
++ * break things again since the i2c-mux code expects the root-adapter to have
++ * a locking depth of 0. But we always have only 1 client directly attached
++ * in the form of the Charger IC paired with the CHT Whiskey Cove PMIC.

++ * to read bytes of instruction which caused #NPF. In this case,
++ * GuestIntrBytes field of the VMCB on a VMEXIT will incorrectly
++ * return 0 instead of the correct guest instruction bytes.
++ *
++ * This happens because CPU microcode reading instruction bytes
++ * uses a special opcode which attempts to read data using CPL=0
++ * priviledges. The microcode reads CS:RIP and if it hits a SMAP
++ * fault, it gives up and returns no instruction bytes.
++ *
++ * Detection:
++ * We reach here in case CPU supports DecodeAssist, raised #NPF and
++ * returned 0 in GuestIntrBytes field of the VMCB.
++ * First, errata can only be triggered in case vCPU CR4.SMAP=1.
++ * Second, if vCPU CR4.SMEP=1, errata could only be triggered
++ * in case vCPU CPL==3 (Because otherwise guest would have triggered
++ * a SMEP fault instead of #NPF).
++ * Otherwise, vCPU CR4.SMEP=0, errata could be triggered by any vCPU CPL.
++ * As most guests enable SMAP if they have also enabled SMEP, use above
++ * logic in order to attempt minimize false-positive of detecting errata
++ * while still preserving all cases semantic correctness.
++ *
++ * Workaround:
++ * To determine what instruction the guest was executing, the hypervisor

+-Known bugs
+-==========
+-
+-skb_orphan() leaks clear text
+------------------------------
+-
+-Currently drivers depend on the :c:member:`sk` member of
+-:c:type:`struct sk_buff <sk_buff>` to identify segments requiring
+-encryption. Any operation which removes or does not preserve the socket
+-association such as :c:func:`skb_orphan` or :c:func:`skb_clone`
+-will cause the driver to miss the packets and lead to clear text leaks.
+-
+-Redirects leak clear text
+--------------------------
+-
+-In the RX direction, if segment has already been decrypted by the device
+-and it gets redirected or mirrored - clear text will be transmitted out.

-Subject: mm/vmalloc: Sync unmappings in __purge_vmap_area_lazy()
-
-On x86-32 with PTI enabled, parts of the kernel page-tables are not shared
-between processes. This can cause mappings in the vmalloc/ioremap area to
-persist in some page-tables after the region is unmapped and released.
-
-When the region is re-used the processes with the old mappings do not fault
-in the new mappings but still access the old ones.
-
-This causes undefined behavior, in reality often data corruption, kernel
-oopses and panics and even spontaneous reboots.
-
-Fix this problem by activly syncing unmaps in the vmalloc/ioremap area to
-all page-tables in the system before the regions can be re-used.
-
-References: https://bugzilla.suse.com/show_bug.cgi?id=1118689
-Fixes: 5d72b4fba40ef ('x86, mm: support huge I/O mapping capability I/F')

++Spectre variant 1 (swapgs)
++~~~~~~~~~~~~~~~~~~~~~~~~~~
++
++ An attacker can train the branch predictor to speculatively skip the
++ swapgs path for an interrupt or exception. If they initialize
++ the GS register to a user-space value, if the swapgs is speculatively
++ skipped, subsequent GS-related percpu accesses in the speculation
++ window will be done with the attacker-controlled GS value. This
++ could cause privileged memory to be accessed and leaked.
++
++ For example:
++
++ ::
++
++ if (coming from user space)
++ swapgs
++ mov %gs:<percpu_offset>, %reg
++ mov (%reg), %reg1
++
++ When coming from user space, the CPU can speculatively skip the
++ swapgs, and then do a speculative percpu load using the user GS
++ value. So the user can speculatively force a read of any kernel
++ value. If a gadget exists which uses the percpu value as an address
++ in another load/store, then the contents of the kernel value may
++ become visible via an L1 side channel attack.
++
++ A similar attack exists when coming from kernel space. The CPU can
++ speculatively do the swapgs, causing the user GS to get used for the
++ rest of the speculative window.

++
+ For the Spectre variant 1, vulnerable kernel code (as determined

+Subject: mm/vmalloc: Sync unmappings in __purge_vmap_area_lazy()
+
+On x86-32 with PTI enabled, parts of the kernel page-tables are not shared
+between processes. This can cause mappings in the vmalloc/ioremap area to
+persist in some page-tables after the region is unmapped and released.
+
+When the region is re-used the processes with the old mappings do not fault
+in the new mappings but still access the old ones.
+
+This causes undefined behavior, in reality often data corruption, kernel
+oopses and panics and even spontaneous reboots.
+
+Fix this problem by activly syncing unmaps in the vmalloc/ioremap area to
+all page-tables in the system before the regions can be re-used.
+
+References: https://bugzilla.suse.com/show_bug.cgi?id=1118689
+Fixes: 5d72b4fba40ef ('x86, mm: support huge I/O mapping capability I/F')

++/*
++ * According to "Inside Macintosh: Devices", Mac OS requires disk drivers to
++ * specify the number of bytes between the delays expected from a SCSI target.
++ * This allows the operating system to "prevent bus errors when a target fails
++ * to deliver the next byte within the processor bus error timeout period."
++ * Linux SCSI drivers lack knowledge of the timing behaviour of SCSI targets
++ * so bus errors are unavoidable.
++ *
++ * If a MOVE.B instruction faults, we assume that zero bytes were transferred
++ * and simply retry. That assumption probably depends on target behaviour but
++ * seems to hold up okay. The NOP provides synchronization: without it the
++ * fault can sometimes occur after the program counter has moved past the
++ * offending instruction. Post-increment addressing can't be used.

++Spectre Side Channels
++=====================
++
++Spectre is a class of side channel attacks that exploit branch prediction
++and speculative execution on modern CPUs to read memory, possibly
++bypassing access controls. Speculative execution side channel exploits
++do not modify memory but attempt to infer privileged data in the memory.
++
++This document covers Spectre variant 1 and Spectre variant 2.
++
++Affected processors

++Speculative execution side channel methods affect a wide range of modern
++high performance processors, since most modern high speed processors
++use branch prediction and speculative execution.
++
++The following CPUs are vulnerable:
++
++ - Intel Core, Atom, Pentium, and Xeon processors
++
++ - AMD Phenom, EPYC, and Zen processors
++
++ - IBM POWER and zSeries processors
++
++ - Higher end ARM processors
++
++ - Apple CPUs
++
++ - Higher end MIPS CPUs
++
++ - Likely most other high performance CPUs. Contact your CPU vendor for details.
++
++Whether a processor is affected or not can be read out from the Spectre
++vulnerability files in sysfs. See :ref:`spectre_sys_info`.

++The following CVE entries describe Spectre variants:
++
++ ============= ======================= =================
++ CVE-2017-5753 Bounds check bypass Spectre variant 1
++ CVE-2017-5715 Branch target injection Spectre variant 2
++ ============= ======================= =================
++
++Problem
++-------
++
++CPUs use speculative operations to improve performance. That may leave
++traces of memory accesses or computations in the processor's caches,
++buffers, and branch predictors. Malicious software may be able to
++influence the speculative execution paths, and then use the side effects
++of the speculative execution in the CPUs' caches and buffers to infer
++privileged data touched during the speculative execution.
++
++Spectre variant 1 attacks take advantage of speculative execution of
++conditional branches, while Spectre variant 2 attacks use speculative
++execution of indirect branches to leak privileged memory.
++See :ref:`[1] <spec_ref1>` :ref:`[5] <spec_ref5>` :ref:`[7] <spec_ref7>`
++:ref:`[10] <spec_ref10>` :ref:`[11] <spec_ref11>`.
++
++Spectre variant 1 (Bounds Check Bypass)
++---------------------------------------
++
++The bounds check bypass attack :ref:`[2] <spec_ref2>` takes advantage
++of speculative execution that bypasses conditional branch instructions
++used for memory access bounds check (e.g. checking if the index of an
++array results in memory access within a valid range). This results in
++memory accesses to invalid memory (with out-of-bound index) that are
++done speculatively before validation checks resolve. Such speculative
++memory accesses can leave side effects, creating side channels which
++leak information to the attacker.
++
++There are some extensions of Spectre variant 1 attacks for reading data
++over the network, see :ref:`[12] <spec_ref12>`. However such attacks
++are difficult, low bandwidth, fragile, and are considered low risk.
++
++Spectre variant 2 (Branch Target Injection)
++-------------------------------------------
++
++The branch target injection attack takes advantage of speculative
++execution of indirect branches :ref:`[3] <spec_ref3>`. The indirect
++branch predictors inside the processor used to guess the target of
++indirect branches can be influenced by an attacker, causing gadget code
++to be speculatively executed, thus exposing sensitive data touched by
++the victim. The side effects left in the CPU's caches during speculative
++execution can be measured to infer data values.
++
++.. _poison_btb:
++
++In Spectre variant 2 attacks, the attacker can steer speculative indirect
++branches in the victim to gadget code by poisoning the branch target
++buffer of a CPU used for predicting indirect branch addresses. Such
++poisoning could be done by indirect branching into existing code,
++with the address offset of the indirect branch under the attacker's
++control. Since the branch prediction on impacted hardware does not
++fully disambiguate branch address and uses the offset for prediction,
++this could cause privileged code's indirect branch to jump to a gadget
++code with the same offset.
++
++The most useful gadgets take an attacker-controlled input parameter (such
++as a register value) so that the memory read can be controlled. Gadgets
++without input parameters might be possible, but the attacker would have
++very little control over what memory can be read, reducing the risk of
++the attack revealing useful data.
++
++One other variant 2 attack vector is for the attacker to poison the
++return stack buffer (RSB) :ref:`[13] <spec_ref13>` to cause speculative
++subroutine return instruction execution to go to a gadget. An attacker's
++imbalanced subroutine call instructions might "poison" entries in the
++return stack buffer which are later consumed by a victim's subroutine
++return instructions. This attack can be mitigated by flushing the return
++stack buffer on context switch, or virtual machine (VM) exit.
++
++On systems with simultaneous multi-threading (SMT), attacks are possible
++from the sibling thread, as level 1 cache and branch target buffer
++(BTB) may be shared between hardware threads in a CPU core. A malicious
++program running on the sibling thread may influence its peer's BTB to
++steer its indirect branch speculations to gadget code, and measure the
++speculative execution's side effects left in level 1 cache to infer the
++victim's data.
++
++Attack scenarios
++----------------
++
++The following list of attack scenarios have been anticipated, but may
++not cover all possible attack vectors.
++
++1. A user process attacking the kernel
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ The attacker passes a parameter to the kernel via a register or
++ via a known address in memory during a syscall. Such parameter may
++ be used later by the kernel as an index to an array or to derive
++ a pointer for a Spectre variant 1 attack. The index or pointer
++ is invalid, but bound checks are bypassed in the code branch taken
++ for speculative execution. This could cause privileged memory to be
++ accessed and leaked.
++
++ For kernel code that has been identified where data pointers could
++ potentially be influenced for Spectre attacks, new "nospec" accessor
++ macros are used to prevent speculative loading of data.
++
++ Spectre variant 2 attacker can :ref:`poison <poison_btb>` the branch
++ target buffer (BTB) before issuing syscall to launch an attack.
++ After entering the kernel, the kernel could use the poisoned branch
++ target buffer on indirect jump and jump to gadget code in speculative
++ execution.
++
++ If an attacker tries to control the memory addresses leaked during
++ speculative execution, he would also need to pass a parameter to the
++ gadget, either through a register or a known address in memory. After
++ the gadget has executed, he can measure the side effect.
++
++ The kernel can protect itself against consuming poisoned branch
++ target buffer entries by using return trampolines (also known as
++ "retpoline") :ref:`[3] <spec_ref3>` :ref:`[9] <spec_ref9>` for all
++ indirect branches. Return trampolines trap speculative execution paths
++ to prevent jumping to gadget code during speculative execution.
++ x86 CPUs with Enhanced Indirect Branch Restricted Speculation
++ (Enhanced IBRS) available in hardware should use the feature to
++ mitigate Spectre variant 2 instead of retpoline. Enhanced IBRS is
++ more efficient than retpoline.
++
++ There may be gadget code in firmware which could be exploited with
++ Spectre variant 2 attack by a rogue user process. To mitigate such
++ attacks on x86, Indirect Branch Restricted Speculation (IBRS) feature
++ is turned on before the kernel invokes any firmware code.
++
++2. A user process attacking another user process
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ A malicious user process can try to attack another user process,
++ either via a context switch on the same hardware thread, or from the
++ sibling hyperthread sharing a physical processor core on simultaneous
++ multi-threading (SMT) system.
++
++ Spectre variant 1 attacks generally require passing parameters
++ between the processes, which needs a data passing relationship, such
++ as remote procedure calls (RPC). Those parameters are used in gadget
++ code to derive invalid data pointers accessing privileged memory in
++ the attacked process.
++
++ Spectre variant 2 attacks can be launched from a rogue process by
++ :ref:`poisoning <poison_btb>` the branch target buffer. This can
++ influence the indirect branch targets for a victim process that either
++ runs later on the same hardware thread, or running concurrently on
++ a sibling hardware thread sharing the same physical core.
++
++ A user process can protect itself against Spectre variant 2 attacks
++ by using the prctl() syscall to disable indirect branch speculation
++ for itself. An administrator can also cordon off an unsafe process
++ from polluting the branch target buffer by disabling the process's
++ indirect branch speculation. This comes with a performance cost
++ from not using indirect branch speculation and clearing the branch
++ target buffer. When SMT is enabled on x86, for a process that has
++ indirect branch speculation disabled, Single Threaded Indirect Branch
++ Predictors (STIBP) :ref:`[4] <spec_ref4>` are turned on to prevent the
++ sibling thread from controlling branch target buffer. In addition,
++ the Indirect Branch Prediction Barrier (IBPB) is issued to clear the
++ branch target buffer when context switching to and from such process.
++
++ On x86, the return stack buffer is stuffed on context switch.
++ This prevents the branch target buffer from being used for branch
++ prediction when the return stack buffer underflows while switching to
++ a deeper call stack. Any poisoned entries in the return stack buffer
++ left by the previous process will also be cleared.
++
++ User programs should use address space randomization to make attacks
++ more difficult (Set /proc/sys/kernel/randomize_va_space = 1 or 2).
++
++3. A virtualized guest attacking the host
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ The attack mechanism is similar to how user processes attack the
++ kernel. The kernel is entered via hyper-calls or other virtualization
++ exit paths.
++
++ For Spectre variant 1 attacks, rogue guests can pass parameters
++ (e.g. in registers) via hyper-calls to derive invalid pointers to
++ speculate into privileged memory after entering the kernel. For places
++ where such kernel code has been identified, nospec accessor macros
++ are used to stop speculative memory access.
++
++ For Spectre variant 2 attacks, rogue guests can :ref:`poison
++ <poison_btb>` the branch target buffer or return stack buffer, causing
++ the kernel to jump to gadget code in the speculative execution paths.
++
++ To mitigate variant 2, the host kernel can use return trampolines
++ for indirect branches to bypass the poisoned branch target buffer,
++ and flushing the return stack buffer on VM exit. This prevents rogue
++ guests from affecting indirect branching in the host kernel.
++
++ To protect host processes from rogue guests, host processes can have
++ indirect branch speculation disabled via prctl(). The branch target
++ buffer is cleared before context switching to such processes.
++
++4. A virtualized guest attacking other guest
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ A rogue guest may attack another guest to get data accessible by the
++ other guest.
++
++ Spectre variant 1 attacks are possible if parameters can be passed
++ between guests. This may be done via mechanisms such as shared memory
++ or message passing. Such parameters could be used to derive data
++ pointers to privileged data in guest. The privileged data could be
++ accessed by gadget code in the victim's speculation paths.
++
++ Spectre variant 2 attacks can be launched from a rogue guest by
++ :ref:`poisoning <poison_btb>` the branch target buffer or the return
++ stack buffer. Such poisoned entries could be used to influence
++ speculation execution paths in the victim guest.
++
++ Linux kernel mitigates attacks to other guests running in the same
++ CPU hardware thread by flushing the return stack buffer on VM exit,
++ and clearing the branch target buffer before switching to a new guest.
++
++ If SMT is used, Spectre variant 2 attacks from an untrusted guest
++ in the sibling hyperthread can be mitigated by the administrator,
++ by turning off the unsafe guest's indirect branch speculation via
++ prctl(). A guest can also protect itself by turning on microcode
++ based mitigations (such as IBPB or STIBP on x86) within the guest.
++
++.. _spectre_sys_info:
++
++Spectre system information
++--------------------------
++
++The Linux kernel provides a sysfs interface to enumerate the current
++mitigation status of the system for Spectre: whether the system is
++vulnerable, and which mitigations are active.
++
++The sysfs file showing Spectre variant 1 mitigation status is:
++
++ /sys/devices/system/cpu/vulnerabilities/spectre_v1
++
++The possible values in this file are:
++
++ ======================================= =================================
++ 'Mitigation: __user pointer sanitation' Protection in kernel on a case by

++ sanitation.
++ ======================================= =================================
++
++However, the protections are put in place on a case by case basis,
++and there is no guarantee that all possible attack vectors for Spectre
++variant 1 are covered.
++
++The spectre_v2 kernel file reports if the kernel has been compiled with
++retpoline mitigation or if the CPU has hardware mitigation, and if the
++CPU has support for additional process-specific mitigation.
++
++This file also reports CPU features enabled by microcode to mitigate
++attack between user processes:
++
++1. Indirect Branch Prediction Barrier (IBPB) to add additional
++ isolation between processes of different users.
++2. Single Thread Indirect Branch Predictors (STIBP) to add additional
++ isolation between CPU threads running on the same core.
++
++These CPU features may impact performance when used and can be enabled
++per process on a case-by-case base.
++
++The sysfs file showing Spectre variant 2 mitigation status is:

++
++Full mitigation might require a microcode update from the CPU
++vendor. When the necessary microcode is not available, the kernel will
++report vulnerability.
++
++Turning on mitigation for Spectre variant 1 and Spectre variant 2
++-----------------------------------------------------------------
++
++1. Kernel mitigation
++^^^^^^^^^^^^^^^^^^^^
++
++ For the Spectre variant 1, vulnerable kernel code (as determined
++ by code audit or scanning tools) is annotated on a case by case
++ basis to use nospec accessor macros for bounds clipping :ref:`[2]
++ <spec_ref2>` to avoid any usable disclosure gadgets. However, it may
++ not cover all attack vectors for Spectre variant 1.
++
++ For Spectre variant 2 mitigation, the compiler turns indirect calls or
++ jumps in the kernel into equivalent return trampolines (retpolines)
++ :ref:`[3] <spec_ref3>` :ref:`[9] <spec_ref9>` to go to the target
++ addresses. Speculative execution paths under retpolines are trapped
++ in an infinite loop to prevent any speculative execution jumping to
++ a gadget.
++
++ To turn on retpoline mitigation on a vulnerable CPU, the kernel
++ needs to be compiled with a gcc compiler that supports the
++ -mindirect-branch=thunk-extern -mindirect-branch-register options.
++ If the kernel is compiled with a Clang compiler, the compiler needs
++ to support -mretpoline-external-thunk option. The kernel config
++ CONFIG_RETPOLINE needs to be turned on, and the CPU needs to run with
++ the latest updated microcode.
++
++ On Intel Skylake-era systems the mitigation covers most, but not all,
++ cases. See :ref:`[3] <spec_ref3>` for more details.
++
++ On CPUs with hardware mitigation for Spectre variant 2 (e.g. Enhanced
++ IBRS on x86), retpoline is automatically disabled at run time.
++
++ The retpoline mitigation is turned on by default on vulnerable
++ CPUs. It can be forced on or off by the administrator
++ via the kernel command line and sysfs control files. See
++ :ref:`spectre_mitigation_control_command_line`.
++
++ On x86, indirect branch restricted speculation is turned on by default
++ before invoking any firmware code to prevent Spectre variant 2 exploits
++ using the firmware.
++
++ Using kernel address space randomization (CONFIG_RANDOMIZE_SLAB=y
++ and CONFIG_SLAB_FREELIST_RANDOM=y in the kernel configuration) makes
++ attacks on the kernel generally more difficult.
++
++2. User program mitigation
++^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ User programs can mitigate Spectre variant 1 using LFENCE or "bounds
++ clipping". For more details see :ref:`[2] <spec_ref2>`.
++
++ For Spectre variant 2 mitigation, individual user programs
++ can be compiled with return trampolines for indirect branches.
++ This protects them from consuming poisoned entries in the branch
++ target buffer left by malicious software. Alternatively, the
++ programs can disable their indirect branch speculation via prctl()
++ (See :ref:`Documentation/userspace-api/spec_ctrl.rst <set_spec_ctrl>`).
++ On x86, this will turn on STIBP to guard against attacks from the
++ sibling thread when the user program is running, and use IBPB to
++ flush the branch target buffer when switching to/from the program.
++
++ Restricting indirect branch speculation on a user program will
++ also prevent the program from launching a variant 2 attack
++ on x86. All sand-boxed SECCOMP programs have indirect branch
++ speculation restricted by default. Administrators can change
++ that behavior via the kernel command line and sysfs control files.
++ See :ref:`spectre_mitigation_control_command_line`.
++
++ Programs that disable their indirect branch speculation will have
++ more overhead and run slower.
++
++ User programs should use address space randomization
++ (/proc/sys/kernel/randomize_va_space = 1 or 2) to make attacks more
++ difficult.
++
++3. VM mitigation
++^^^^^^^^^^^^^^^^
++
++ Within the kernel, Spectre variant 1 attacks from rogue guests are
++ mitigated on a case by case basis in VM exit paths. Vulnerable code
++ uses nospec accessor macros for "bounds clipping", to avoid any
++ usable disclosure gadgets. However, this may not cover all variant
++ 1 attack vectors.
++
++ For Spectre variant 2 attacks from rogue guests to the kernel, the
++ Linux kernel uses retpoline or Enhanced IBRS to prevent consumption of
++ poisoned entries in branch target buffer left by rogue guests. It also
++ flushes the return stack buffer on every VM exit to prevent a return
++ stack buffer underflow so poisoned branch target buffer could be used,
++ or attacker guests leaving poisoned entries in the return stack buffer.
++
++ To mitigate guest-to-guest attacks in the same CPU hardware thread,
++ the branch target buffer is sanitized by flushing before switching
++ to a new guest on a CPU.
++
++ The above mitigations are turned on by default on vulnerable CPUs.
++
++ To mitigate guest-to-guest attacks from sibling thread when SMT is
++ in use, an untrusted guest running in the sibling thread can have
++ its indirect branch speculation disabled by administrator via prctl().
++
++ The kernel also allows guests to use any microcode based mitigation
++ they choose to use (such as IBPB or STIBP on x86) to protect themselves.
++
++.. _spectre_mitigation_control_command_line:
++
++Mitigation control on the kernel command line

++
++Spectre variant 2 mitigation can be disabled or force enabled at the
++kernel command line.

++ [X86] Control mitigation of Spectre variant 2
++ (indirect branch speculation) vulnerability.
++ The default operation protects the kernel from
++ user space attacks.
++
++ on
++ unconditionally enable, implies
++ spectre_v2_user=on
++ off
++ unconditionally disable, implies
++ spectre_v2_user=off
++ auto
++ kernel detects whether your CPU model is
++ vulnerable
++
++ Selecting 'on' will, and 'auto' may, choose a
++ mitigation method at run time according to the
++ CPU, the available microcode, the setting of the
++ CONFIG_RETPOLINE configuration option, and the
++ compiler with which the kernel was built.
++
++ Selecting 'on' will also enable the mitigation
++ against user space to user space task attacks.
++
++ Selecting 'off' will disable both the kernel and
++ the user space protections.
++
++ Specific mitigations can also be selected manually:
++
++ retpoline
++ replace indirect branches
++ retpoline,generic
++ google's original retpoline
++ retpoline,amd
++ AMD-specific minimal thunk
++
++ Not specifying this option is equivalent to
++ spectre_v2=auto.
++
++For user space mitigation:
++
++ spectre_v2_user=
++
++ [X86] Control mitigation of Spectre variant 2
++ (indirect branch speculation) vulnerability between
++ user space tasks
++
++ on
++ Unconditionally enable mitigations. Is
++ enforced by spectre_v2=on
++
++ off
++ Unconditionally disable mitigations. Is
++ enforced by spectre_v2=off
++
++ prctl
++ Indirect branch speculation is enabled,
++ but mitigation can be enabled via prctl
++ per thread. The mitigation control state
++ is inherited on fork.
++
++ prctl,ibpb
++ Like "prctl" above, but only STIBP is
++ controlled per thread. IBPB is issued
++ always when switching between different user
++ space processes.
++
++ seccomp
++ Same as "prctl" above, but all seccomp
++ threads will enable the mitigation unless
++ they explicitly opt out.
++
++ seccomp,ibpb
++ Like "seccomp" above, but only STIBP is
++ controlled per thread. IBPB is issued
++ always when switching between different
++ user space processes.
++
++ auto
++ Kernel selects the mitigation depending on
++ the available CPU features and vulnerability.
++
++ Default mitigation:
++ If CONFIG_SECCOMP=y then "seccomp", otherwise "prctl"
++
++ Not specifying this option is equivalent to
++ spectre_v2_user=auto.
++
++ In general the kernel by default selects
++ reasonable mitigations for the current CPU. To
++ disable Spectre variant 2 mitigations, boot with
++ spectre_v2=off. Spectre variant 1 mitigations
++ cannot be disabled.
++
++Mitigation selection guide
++--------------------------
++
++1. Trusted userspace
++^^^^^^^^^^^^^^^^^^^^
++
++ If all userspace applications are from trusted sources and do not
++ execute externally supplied untrusted code, then the mitigations can
++ be disabled.
++
++2. Protect sensitive programs
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ For security-sensitive programs that have secrets (e.g. crypto
++ keys), protection against Spectre variant 2 can be put in place by
++ disabling indirect branch speculation when the program is running
++ (See :ref:`Documentation/userspace-api/spec_ctrl.rst <set_spec_ctrl>`).
++
++3. Sandbox untrusted programs
++^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++
++ Untrusted programs that could be a source of attacks can be cordoned
++ off by disabling their indirect branch speculation when they are run
++ (See :ref:`Documentation/userspace-api/spec_ctrl.rst <set_spec_ctrl>`).
++ This prevents untrusted programs from polluting the branch target
++ buffer. All programs running in SECCOMP sandboxes have indirect
++ branch speculation restricted by default. This behavior can be
++ changed via the kernel command line and sysfs control files. See
++ :ref:`spectre_mitigation_control_command_line`.
++
++3. High security mode
++^^^^^^^^^^^^^^^^^^^^^
++
++ All Spectre variant 2 mitigations can be forced on
++ at boot time for all programs (See the "on" option in
++ :ref:`spectre_mitigation_control_command_line`). This will add
++ overhead as indirect branch speculations for all programs will be
++ restricted.
++
++ On x86, branch target buffer will be flushed with IBPB when switching
++ to a new program. STIBP is left on all the time to protect programs
++ against variant 2 attacks originating from programs running on
++ sibling threads.
++
++ Alternatively, STIBP can be used only when running programs
++ whose indirect branch speculation is explicitly disabled,
++ while IBPB is still used all the time when switching to a new
++ program to clear the branch target buffer (See "ibpb" option in
++ :ref:`spectre_mitigation_control_command_line`). This "ibpb" option
++ has less performance cost than the "on" option, which leaves STIBP
++ on all the time.
