-The primary ioctl to resolve userfaults is ``UFFDIO_COPY``. That
-atomically copies a page into the userfault registered range and wakes
-up the blocked userfaults
-(unless ``uffdio_copy.mode & UFFDIO_COPY_MODE_DONTWAKE`` is set).
-Other ioctl works similarly to ``UFFDIO_COPY``. They're atomic as in
-guaranteeing that nothing can see an half copied page since it'll
-keep userfaulting until the copy has finished.
+Resolving Userfaults
+--------------------
+
+There are three basic ways to resolve userfaults:
+
+- ``UFFDIO_COPY`` atomically copies some existing page contents from
+  userspace.
+
+- ``UFFDIO_ZEROPAGE`` atomically zeros the new page.
+
+- ``UFFDIO_CONTINUE`` maps an existing, previously-populated page.
+
+These operations are atomic in the sense that they guarantee nothing can
+see a half-populated page, since readers will keep userfaulting until the
+operation has finished.
+
+By default, these wake up userfaults blocked on the range in question.
+They support a ``UFFDIO_*_MODE_DONTWAKE`` ``mode`` flag, which indicates
+that waking will be done separately at some later time.
+
+Which ioctl to choose depends on the kind of page fault, and what we'd
+like to do to resolve it:
+
+- For ``UFFDIO_REGISTER_MODE_MISSING`` faults, the fault needs to be
+  resolved by either providing a new page (``UFFDIO_COPY``), or mapping
+  the zero page (``UFFDIO_ZEROPAGE``). By default, the kernel would map
+  the zero page for a missing fault. With userfaultfd, userspace can
+  decide what content to provide before the faulting thread continues.
+
+- For ``UFFDIO_REGISTER_MODE_MINOR`` faults, there is an existing page (in
+  the page cache). Userspace has the option of modifying the page's
+  contents before resolving the fault. Once the contents are correct
+  (modified or not), userspace asks the kernel to map the page and let the
+  faulting thread continue with ``UFFDIO_CONTINUE``.

+This mode is supported in GCC 10+ and Clang 11+.
+
+Both software KASAN modes work with SLUB and SLAB memory allocators,
+while the hardware tag-based KASAN currently only supports SLUB.
+
+Currently, generic KASAN is supported for the x86_64, arm, arm64, xtensa, s390,
 and riscv architectures, and tag-based KASAN modes are supported only for arm64.

+Ignoring accesses
+~~~~~~~~~~~~~~~~~
+
+Software KASAN modes use compiler instrumentation to insert validity checks.
+Such instrumentation might be incompatible with some parts of the kernel, and
+therefore needs to be disabled.
+
+Other parts of the kernel might access metadata for allocated objects.
+Normally, KASAN detects and reports such accesses, but in some cases (e.g.,
+in memory allocators), these accesses are valid.
+
+For software KASAN modes, to disable instrumentation for a specific file or
+directory, add a ``KASAN_SANITIZE`` annotation to the respective kernel
+Makefile:
+
+- For a single file (e.g., main.o)::
 
-KASAN tests consist of two parts:
+    KASAN_SANITIZE_main.o := n
+
+- For all files in one directory::
+
+    KASAN_SANITIZE := n
+
+For software KASAN modes, to disable instrumentation on a per-function basis,
+use the KASAN-specific ``__no_sanitize_address`` function attribute or the
+generic ``noinstr`` one.
+
+Note that disabling compiler instrumentation (either on a per-file or a
+per-function basis) makes KASAN ignore the accesses that happen directly in
+that code for software KASAN modes. It does not help when the accesses happen
+indirectly (through calls to instrumented functions) or with the hardware
+tag-based mode that does not use compiler instrumentation.
+
+For software KASAN modes, to disable KASAN reports in a part of the kernel code
+for the current task, annotate this part of the code with a
+``kasan_disable_current()``/``kasan_enable_current()`` section. This also
+disables the reports for indirect accesses that happen through function calls.
+
+For tag-based KASAN modes (include the hardware one), to disable access
+checking, use ``kasan_reset_tag()`` or ``page_kasan_tag_reset()``. Note that
+temporarily disabling access checking via ``page_kasan_tag_reset()`` requires
+saving and restoring the per-page KASAN tag via

+  Arm Trace Buffer Extension (TRBE) is a per CPU component
+  for storing trace generated on the CPU to memory. It is
+  accessed via CPU system registers. The software can verify
+  if it is permitted to use the component by checking the
+  TRBIDR register.

+description: |
+  Realtek's GPIO controller on their MIPS switch SoCs (Otto platform) consists
+  of two banks of 32 GPIOs. These GPIOs can generate edge-triggered interrupts.
+  Each bank's interrupts are cascased into one interrupt line on the parent
+  interrupt controller, if provided.
+  This binding allows defining a single bank in the devicetree. The interrupt
+  controller is not supported on the fallback compatible name, which only
+  allows for GPIO port use.

-
-Required properties :
-
- - reg : Offset and length of the register set for the device
- - compatible : should be "fsl,CHIP-i2c" where CHIP is the name of a
-   compatible processor, e.g. mpc8313, mpc8543, mpc8544, mpc5121,
-   mpc5200 or mpc5200b. For the mpc5121, an additional node
-   "fsl,mpc5121-i2c-ctrl" is required as shown in the example below.
-
-Recommended properties :
-
- - interrupts : <a b> where a is the interrupt number and b is a
-   field that represents an encoding of the sense and level
-   information for the interrupt.  This should be encoded based on
-   the information in section 2) depending on the type of interrupt
-   controller you have.
- - fsl,preserve-clocking : boolean; if defined, the clock settings
-   from the bootloader are preserved (not touched).
- - clock-frequency : desired I2C bus clock frequency in Hz.
- - fsl,timeout : I2C bus timeout in microseconds.
-
-Examples :

-				  "azoteq,iqs572"
-				  "azoteq,iqs525"
-
-- reg				: I2C slave address for the device.

-
-- reset-gpios			: GPIO to which the device's active-low NRST
-				  input is connected (see [1]).
-
-Optional properties:
-
-- touchscreen-min-x		: See [2].
-
-- touchscreen-min-y		: See [2].
-
-- touchscreen-size-x		: See [2]. If this property is omitted, the
-				  maximum x-coordinate is specified by the
-				  device's "X Resolution" register.
-
-- touchscreen-size-y		: See [2]. If this property is omitted, the
-				  maximum y-coordinate is specified by the
-				  device's "Y Resolution" register.
-
-- touchscreen-max-pressure	: See [2]. Pressure is expressed as the sum of
-				  the deltas across all channels impacted by a
-				  touch event. A channel's delta is calculated
-				  as its count value minus a reference, where
-				  the count value is inversely proportional to

-
-- touchscreen-fuzz-y		: See [2].
-
-- touchscreen-fuzz-pressure	: See [2].
-
-- touchscreen-inverted-x	: See [2]. Inversion is applied relative to that
-				  which may already be specified by the device's
-				  FLIP_X and FLIP_Y register fields.
-
-- touchscreen-inverted-y	: See [2]. Inversion is applied relative to that
-				  which may already be specified by the device's
-				  FLIP_X and FLIP_Y register fields.

-HiSilicon Hip05 and Hip06 PCIe host bridge DT description
-
-HiSilicon PCIe host controller is based on the Synopsys DesignWare PCI core.
-It shares common functions with the PCIe DesignWare core driver and inherits
-common properties defined in
-Documentation/devicetree/bindings/pci/designware-pcie.txt.
-
-Additional properties are described here:
-
-Required properties
-- compatible: Should contain "hisilicon,hip05-pcie" or "hisilicon,hip06-pcie".
-- reg: Should contain rc_dbi, config registers location and length.
-- reg-names: Must include the following entries:
-  "rc_dbi": controller configuration registers;
-  "config": PCIe configuration space registers.
-- msi-parent: Should be its_pcie which is an ITS receiving MSI interrupts.
-- port-id: Should be 0, 1, 2 or 3.
-
-Optional properties:
-- status: Either "ok" or "disabled".
-- dma-coherent: Present if DMA operations are coherent.
-
-Hip05 Example (note that Hip06 is the same except compatible):
-	pcie@b0080000 {
-		compatible = "hisilicon,hip05-pcie", "snps,dw-pcie";
-		reg = <0 0xb0080000 0 0x10000>, <0x220 0x00000000 0 0x2000>;

+description: |
+  Please refer to pinctrl-bindings.txt in this directory for details of the
+  common pinctrl bindings used by client devices, including the meaning of the
+  phrase "pin configuration node".
+
+  ZynqMP's pin configuration nodes act as a container for an arbitrary number of
+  subnodes. Each of these subnodes represents some desired configuration for a
+  pin, a group, or a list of pins or groups. This configuration can include the
+  mux function to select on those pin(s)/group(s), and various pin configuration
+  parameters, such as pull-up, slew rate, etc.
+
+  Each configuration node can consist of multiple nodes describing the pinmux and
+  pinconf options. Those nodes can be pinmux nodes or pinconf nodes.
+
+  The name of each subnode is not important; all subnodes should be enumerated
+  and processed purely based on their content.

-Rockchip PWM controller
-
-Required properties:
- - compatible: should be "rockchip,<name>-pwm"
-   "rockchip,rk2928-pwm": found on RK29XX,RK3066 and RK3188 SoCs
-   "rockchip,rk3288-pwm": found on RK3288 SOC
-   "rockchip,rv1108-pwm", "rockchip,rk3288-pwm": found on RV1108 SoC
-   "rockchip,vop-pwm": found integrated in VOP on RK3288 SoC
- - reg: physical base address and length of the controller's registers
- - clocks: See ../clock/clock-bindings.txt
-   - For older hardware (rk2928, rk3066, rk3188, rk3228, rk3288, rk3399):
-     - There is one clock that's used both to derive the functional clock
-       for the device and as the bus clock.
-   - For newer hardware (rk3328 and future socs): specified by name
-     - "pwm": This is used to derive the functional clock.
-     - "pclk": This is the APB bus clock.
- - #pwm-cells: must be 2 (rk2928) or 3 (rk3288). See pwm.yaml in this directory
-   for a description of the cell format.
-
-Example:
-
-	pwm0: pwm@20030000 {
-		compatible = "rockchip,rk2928-pwm";
-		reg = <0x20030000 0x10>;
-		clocks = <&cru PCLK_PWM01>;
-		#pwm-cells = <2>;

+description:
+  The I2SMCC complies with the Inter-IC Sound (I2S) bus specification and
+  supports a Time Division Multiplexed (TDM) interface with external
+  multi-channel audio codecs. It consists of a receiver, a transmitter and a
+  common clock generator that can be enabled separately to provide Adapter,
+  Client or Controller modes with receiver and/or transmitter active.
+  On later I2SMCC versions (starting with Microchip's SAMA7G5) I2S
+  multi-channel is supported by using multiple data pins, output and
+  input, without TDM.

+Landlock LSM: kernel documentation
+==================================
+
+:Author: Mickaël Salaün
+:Date: March 2021
+
+Landlock's goal is to create scoped access-control (i.e. sandboxing).  To
+harden a whole system, this feature should be available to any process,
+including unprivileged ones.  Because such process may be compromised or
+backdoored (i.e. untrusted), Landlock's features must be safe to use from the
+kernel and other processes point of view.  Landlock's interface must therefore
+expose a minimal attack surface.
+
+Landlock is designed to be usable by unprivileged processes while following the
+system security policy enforced by other access control mechanisms (e.g. DAC,
+LSM).  Indeed, a Landlock rule shall not interfere with other access-controls
+enforced on the system, only add more restrictions.
+
+Any user can enforce Landlock rulesets on their processes.  They are merged and
+evaluated according to the inherited ones in a way that ensures that only more
+constraints can be added.
+
+User space documentation can be found here: :doc:`/userspace-api/landlock`.
+
+Guiding principles for safe access controls
+===========================================
+
+* A Landlock rule shall be focused on access control on kernel objects instead
+  of syscall filtering (i.e. syscall arguments), which is the purpose of
+  seccomp-bpf.
+* To avoid multiple kinds of side-channel attacks (e.g. leak of security
+  policies, CPU-based attacks), Landlock rules shall not be able to
+  programmatically communicate with user space.
+* Kernel access check shall not slow down access request from unsandboxed
+  processes.
+* Computation related to Landlock operations (e.g. enforcing a ruleset) shall
+  only impact the processes requesting them.
+
+Tests
+=====
+
+Userspace tests for backward compatibility, ptrace restrictions and filesystem
+support can be found here: `tools/testing/selftests/landlock/`_.

+Ruleset and domain
+------------------
+
+A domain is a read-only ruleset tied to a set of subjects (i.e. tasks'
+credentials).  Each time a ruleset is enforced on a task, the current domain is
+duplicated and the ruleset is imported as a new layer of rules in the new
+domain.  Indeed, once in a domain, each rule is tied to a layer level.  To
+grant access to an object, at least one rule of each layer must allow the
+requested action on the object.  A task can then only transit to a new domain
+that is the intersection of the constraints from the current domain and those
+of a ruleset provided by the task.
+
+The definition of a subject is implicit for a task sandboxing itself, which
+makes the reasoning much easier and helps avoid pitfalls.

+Trace Buffer Extension (TRBE).
+==============================
+
+    :Author:   Anshuman Khandual <anshuman.khandual@arm.com>
+    :Date:     November 2020
+
+Hardware Description
+--------------------
+
+Trace Buffer Extension (TRBE) is a percpu hardware which captures in system
+memory, CPU traces generated from a corresponding percpu tracing unit. This
+gets plugged in as a coresight sink device because the corresponding trace
+generators (ETE), are plugged in as source device.
+
+The TRBE is not compliant to CoreSight architecture specifications, but is
+driven via the CoreSight driver framework to support the ETE (which is
+CoreSight compliant) integration.
+
+Sysfs files and directories
+---------------------------
+
+The TRBE devices appear on the existing coresight bus alongside the other
+coresight devices::
+
+	>$ ls /sys/bus/coresight/devices
+	trbe0  trbe1  trbe2 trbe3
+
+The ``trbe<N>`` named TRBEs are associated with a CPU.::
+
+	>$ ls /sys/bus/coresight/devices/trbe0/
+        align flag
+
+*Key file items are:-*
+   * ``align``: TRBE write pointer alignment
+   * ``flag``: TRBE updates memory with access and dirty flags

+Landlock: unprivileged access control
+=====================================
+
+:Author: Mickaël Salaün
+:Date: March 2021
+
+The goal of Landlock is to enable to restrict ambient rights (e.g. global
+filesystem access) for a set of processes.  Because Landlock is a stackable
+LSM, it makes possible to create safe security sandboxes as new security layers
+in addition to the existing system-wide access-controls. This kind of sandbox
+is expected to help mitigate the security impact of bugs or
+unexpected/malicious behaviors in user space applications.  Landlock empowers
+any process, including unprivileged ones, to securely restrict themselves.
+
+Landlock rules
+==============
+
+A Landlock rule describes an action on an object.  An object is currently a
+file hierarchy, and the related filesystem actions are defined with `access
+rights`_.  A set of rules is aggregated in a ruleset, which can then restrict
+the thread enforcing it, and its future children.
+
+Defining and enforcing a security policy
+----------------------------------------
+
+We first need to create the ruleset that will contain our rules.  For this
+example, the ruleset will contain rules that only allow read actions, but write
+actions will be denied.  The ruleset then needs to handle both of these kind of
+actions.
+
+.. code-block:: c
+
+    int ruleset_fd;
+    struct landlock_ruleset_attr ruleset_attr = {
+        .handled_access_fs =
+            LANDLOCK_ACCESS_FS_EXECUTE |
+            LANDLOCK_ACCESS_FS_WRITE_FILE |
+            LANDLOCK_ACCESS_FS_READ_FILE |
+            LANDLOCK_ACCESS_FS_READ_DIR |
+            LANDLOCK_ACCESS_FS_REMOVE_DIR |
+            LANDLOCK_ACCESS_FS_REMOVE_FILE |
+            LANDLOCK_ACCESS_FS_MAKE_CHAR |
+            LANDLOCK_ACCESS_FS_MAKE_DIR |
+            LANDLOCK_ACCESS_FS_MAKE_REG |
+            LANDLOCK_ACCESS_FS_MAKE_SOCK |
+            LANDLOCK_ACCESS_FS_MAKE_FIFO |
+            LANDLOCK_ACCESS_FS_MAKE_BLOCK |
+            LANDLOCK_ACCESS_FS_MAKE_SYM,
+    };
+
+    ruleset_fd = landlock_create_ruleset(&ruleset_attr, sizeof(ruleset_attr), 0);
+    if (ruleset_fd < 0) {
+        perror("Failed to create a ruleset");
+        return 1;
+    }
+
+We can now add a new rule to this ruleset thanks to the returned file
+descriptor referring to this ruleset.  The rule will only allow reading the
+file hierarchy ``/usr``.  Without another rule, write actions would then be
+denied by the ruleset.  To add ``/usr`` to the ruleset, we open it with the
+``O_PATH`` flag and fill the &struct landlock_path_beneath_attr with this file
+descriptor.
+
+.. code-block:: c
+
+    int err;
+    struct landlock_path_beneath_attr path_beneath = {
+        .allowed_access =
+            LANDLOCK_ACCESS_FS_EXECUTE |
+            LANDLOCK_ACCESS_FS_READ_FILE |
+            LANDLOCK_ACCESS_FS_READ_DIR,
+    };
+
+    path_beneath.parent_fd = open("/usr", O_PATH | O_CLOEXEC);
+    if (path_beneath.parent_fd < 0) {
+        perror("Failed to open file");
+        close(ruleset_fd);
+        return 1;
+    }
+    err = landlock_add_rule(ruleset_fd, LANDLOCK_RULE_PATH_BENEATH,
+                            &path_beneath, 0);
+    close(path_beneath.parent_fd);
+    if (err) {
+        perror("Failed to update ruleset");
+        close(ruleset_fd);
+        return 1;
+    }
+
+We now have a ruleset with one rule allowing read access to ``/usr`` while
+denying all other handled accesses for the filesystem.  The next step is to
+restrict the current thread from gaining more privileges (e.g. thanks to a SUID
+binary).
+
+.. code-block:: c
+
+    if (prctl(PR_SET_NO_NEW_PRIVS, 1, 0, 0, 0)) {
+        perror("Failed to restrict privileges");
+        close(ruleset_fd);
+        return 1;
+    }
+
+The current thread is now ready to sandbox itself with the ruleset.
+
+.. code-block:: c
+
+    if (landlock_restrict_self(ruleset_fd, 0)) {
+        perror("Failed to enforce ruleset");
+        close(ruleset_fd);
+        return 1;
+    }
+    close(ruleset_fd);
+
+If the `landlock_restrict_self` system call succeeds, the current thread is now
+restricted and this policy will be enforced on all its subsequently created
+children as well.  Once a thread is landlocked, there is no way to remove its
+security policy; only adding more restrictions is allowed.  These threads are
+now in a new Landlock domain, merge of their parent one (if any) with the new
+ruleset.
+
+Full working code can be found in `samples/landlock/sandboxer.c`_.
+
+Layers of file path access rights
+---------------------------------
+
+Each time a thread enforces a ruleset on itself, it updates its Landlock domain
+with a new layer of policy.  Indeed, this complementary policy is stacked with
+the potentially other rulesets already restricting this thread.  A sandboxed
+thread can then safely add more constraints to itself with a new enforced
+ruleset.
+
+One policy layer grants access to a file path if at least one of its rules
+encountered on the path grants the access.  A sandboxed thread can only access
+a file path if all its enforced policy layers grant the access as well as all
+the other system access controls (e.g. filesystem DAC, other LSM policies,
+etc.).
+
+Bind mounts and OverlayFS
+-------------------------
+
+Landlock enables to restrict access to file hierarchies, which means that these
+access rights can be propagated with bind mounts (cf.
+:doc:`/filesystems/sharedsubtree`) but not with :doc:`/filesystems/overlayfs`.
+
+A bind mount mirrors a source file hierarchy to a destination.  The destination
+hierarchy is then composed of the exact same files, on which Landlock rules can
+be tied, either via the source or the destination path.  These rules restrict
+access when they are encountered on a path, which means that they can restrict
+access to multiple file hierarchies at the same time, whether these hierarchies
+are the result of bind mounts or not.
+
+An OverlayFS mount point consists of upper and lower layers.  These layers are
+combined in a merge directory, result of the mount point.  This merge hierarchy
+may include files from the upper and lower layers, but modifications performed
+on the merge hierarchy only reflects on the upper layer.  From a Landlock
+policy point of view, each OverlayFS layers and merge hierarchies are
+standalone and contains their own set of files and directories, which is
+different from bind mounts.  A policy restricting an OverlayFS layer will not
+restrict the resulted merged hierarchy, and vice versa.  Landlock users should
+then only think about file hierarchies they want to allow access to, regardless
+of the underlying filesystem.
+
+Inheritance
+-----------
+
+Every new thread resulting from a :manpage:`clone(2)` inherits Landlock domain
+restrictions from its parent.  This is similar to the seccomp inheritance (cf.
+:doc:`/userspace-api/seccomp_filter`) or any other LSM dealing with task's
+:manpage:`credentials(7)`.  For instance, one process's thread may apply
+Landlock rules to itself, but they will not be automatically applied to other
+sibling threads (unlike POSIX thread credential changes, cf.
+:manpage:`nptl(7)`).
+
+When a thread sandboxes itself, we have the guarantee that the related security
+policy will stay enforced on all this thread's descendants.  This allows
+creating standalone and modular security policies per application, which will
+automatically be composed between themselves according to their runtime parent
+policies.
+
+Ptrace restrictions
+-------------------
+
+A sandboxed process has less privileges than a non-sandboxed process and must
+then be subject to additional restrictions when manipulating another process.
+To be allowed to use :manpage:`ptrace(2)` and related syscalls on a target
+process, a sandboxed process should have a subset of the target process rules,
+which means the tracee must be in a sub-domain of the tracer.

+
+Current limitations
+===================
+
+File renaming and linking
+-------------------------
+
+Because Landlock targets unprivileged access controls, it is needed to properly
+handle composition of rules.  Such property also implies rules nesting.
+Properly handling multiple layers of ruleset, each one of them able to restrict
+access to files, also implies to inherit the ruleset restrictions from a parent
+to its hierarchy.  Because files are identified and restricted by their
+hierarchy, moving or linking a file from one directory to another implies to
+propagate the hierarchy constraints.  To protect against privilege escalations
+through renaming or linking, and for the sake of simplicity, Landlock currently
+limits linking and renaming to the same directory.  Future Landlock evolutions
+will enable more flexibility for renaming and linking, with dedicated ruleset
+flags.
+
+Filesystem topology modification
+--------------------------------
+
+As for file renaming and linking, a sandboxed thread cannot modify its
+filesystem topology, whether via :manpage:`mount(2)` or
+:manpage:`pivot_root(2)`.  However, :manpage:`chroot(2)` calls are not denied.
+
+Special filesystems
+-------------------
+
+Access to regular files and directories can be restricted by Landlock,
+according to the handled accesses of a ruleset.  However, files that do not
+come from a user-visible filesystem (e.g. pipe, socket), but can still be
+accessed through ``/proc/<pid>/fd/*``, cannot currently be explicitly
+restricted.  Likewise, some special kernel filesystems such as nsfs, which can
+be accessed through ``/proc/<pid>/ns/*``, cannot currently be explicitly
+restricted.  However, thanks to the `ptrace restrictions`_, access to such
+sensitive ``/proc`` files are automatically restricted according to domain
+hierarchies.  Future Landlock evolutions could still enable to explicitly
+restrict such paths with dedicated ruleset flags.
+
+Ruleset layers
+--------------
+
+There is a limit of 64 layers of stacked rulesets.  This can be an issue for a
+task willing to enforce a new ruleset in complement to its 64 inherited
+rulesets.  Once this limit is reached, sys_landlock_restrict_self() returns
+E2BIG.  It is then strongly suggested to carefully build rulesets once in the
+life of a thread, especially for applications able to launch other applications
+that may also want to sandbox themselves (e.g. shells, container managers,
+etc.).
+
+Memory usage
+------------
+
+Kernel memory allocated to create rulesets is accounted and can be restricted
+by the :doc:`/admin-guide/cgroup-v1/memory`.
+
+Questions and answers
+=====================
+
+What about user space sandbox managers?
+---------------------------------------
+
+Using user space process to enforce restrictions on kernel resources can lead
+to race conditions or inconsistent evaluations (i.e. `Incorrect mirroring of
+the OS code and state
+<https://www.ndss-symposium.org/ndss2003/traps-and-pitfalls-practical-problems-system-call-interposition-based-security-tools/>`_).
+
+What about namespaces and containers?
+-------------------------------------
+
+Namespaces can help create sandboxes but they are not designed for
+access-control and then miss useful features for such use case (e.g. no
+fine-grained restrictions).  Moreover, their complexity can lead to security
+issues, especially when untrusted processes can manipulate them (cf.
+`Controlling access to user namespaces <https://lwn.net/Articles/673597/>`_).

+        };
+
+12. KVM_SEV_SEND_UPDATE_DATA
+----------------------------
+
+The KVM_SEV_SEND_UPDATE_DATA command can be used by the hypervisor to encrypt the
+outgoing guest memory region with the encryption context creating using
+KVM_SEV_SEND_START.
+
+If hdr_len or trans_len are zero on entry, the length of the packet header and
+transport region are written to hdr_len and trans_len respectively, and all
+other fields are not used.
+
+Parameters (in): struct kvm_sev_send_update_data
+
+Returns: 0 on success, -negative on error
+
+::
+
+        struct kvm_sev_launch_send_update_data {

+                __u32 trans_len;
+        };
+
+13. KVM_SEV_SEND_FINISH
+------------------------
+
+After completion of the migration flow, the KVM_SEV_SEND_FINISH command can be
+issued by the hypervisor to delete the encryption context.
+
+Returns: 0 on success, -negative on error
+
+14. KVM_SEV_SEND_CANCEL
+------------------------
+
+After completion of SEND_START, but before SEND_FINISH, the source VMM can issue the
+SEND_CANCEL command to stop a migration. This is necessary so that a cancelled
+migration can restart with a new target later.
+
+Returns: 0 on success, -negative on error
+
+15. KVM_SEV_RECEIVE_START
+-------------------------
+
+The KVM_SEV_RECEIVE_START command is used for creating the memory encryption
+context for an incoming SEV guest. To create the encryption context, the user must
+provide a guest policy, the platform public Diffie-Hellman (PDH) key and session
+information.
+
+Parameters: struct  kvm_sev_receive_start (in/out)
+
+Returns: 0 on success, -negative on error
+
+::
+
+        struct kvm_sev_receive_start {
+                __u32 handle;           /* if zero then firmware creates a new handle */
+                __u32 policy;           /* guest's policy */
+
+                __u64 pdh_uaddr;        /* userspace address pointing to the PDH key */
+                __u32 pdh_len;
+
+                __u64 session_uaddr;    /* userspace address which points to the guest session information */
+                __u32 session_len;
+        };
+
+On success, the 'handle' field contains a new handle and on error, a negative value.
+
+For more details, see SEV spec Section 6.12.
+
+16. KVM_SEV_RECEIVE_UPDATE_DATA
+-------------------------------
+
+The KVM_SEV_RECEIVE_UPDATE_DATA command can be used by the hypervisor to copy
+the incoming buffers into the guest memory region with encryption context
+created during the KVM_SEV_RECEIVE_START.
+
+Parameters (in): struct kvm_sev_receive_update_data
+
+Returns: 0 on success, -negative on error
+
+::
+
+        struct kvm_sev_launch_receive_update_data {
+                __u64 hdr_uaddr;        /* userspace address containing the packet header */
+                __u32 hdr_len;
+
+                __u64 guest_uaddr;      /* the destination guest memory region */
+                __u32 guest_len;
+
+                __u64 trans_uaddr;      /* the incoming buffer memory region  */
+                __u32 trans_len;
+        };
+
+17. KVM_SEV_RECEIVE_FINISH
+--------------------------
+
+After completion of the migration flow, the KVM_SEV_RECEIVE_FINISH command can be
+issued by the hypervisor to make the guest ready for execution.
+
+Returns: 0 on success, -negative on error

+

+
+``KVM_MSR_FILTER_READ | KVM_MSR_FILTER_WRITE``
+
+  Filter both read and write accesses to MSRs using the given bitmap. A 0
+  in the bitmap indicates that both reads and writes should immediately fail,
+  while a 1 indicates that reads and writes for a particular MSR are not
+  filtered by this range.
+
+flags values for ``struct kvm_msr_filter``:
+
+``KVM_MSR_FILTER_DEFAULT_ALLOW``
+
+  If no filter range matches an MSR index that is getting accessed, KVM will
+  fall back to allowing access to the MSR.
+
+``KVM_MSR_FILTER_DEFAULT_DENY``
+
+  If no filter range matches an MSR index that is getting accessed, KVM will
+  fall back to rejecting access to the MSR. In this mode, all MSRs that should
+  be processed by KVM need to explicitly be marked as allowed in the bitmaps.
+
+This ioctl allows user space to define up to 16 bitmaps of MSR ranges to
+specify whether a certain MSR access should be explicitly filtered for or not.
+
+If this ioctl has never been invoked, MSR accesses are not guarded and the
+default KVM in-kernel emulation behavior is fully preserved.
+
+Calling this ioctl with an empty set of ranges (all nmsrs == 0) disables MSR
+filtering. In that mode, ``KVM_MSR_FILTER_DEFAULT_DENY`` is invalid and causes
+an error.
+
+As soon as the filtering is in place, every MSR access is processed through
+the filtering except for accesses to the x2APIC MSRs (from 0x800 to 0x8ff);
+x2APIC MSRs are always allowed, independent of the ``default_allow`` setting,
+and their behavior depends on the ``X2APIC_ENABLE`` bit of the APIC base
+register.
+
+If a bit is within one of the defined ranges, read and write accesses are
+guarded by the bitmap's value for the MSR index if the kind of access
+is included in the ``struct kvm_msr_filter_range`` flags.  If no range
+cover this particular access, the behavior is determined by the flags
+field in the kvm_msr_filter struct: ``KVM_MSR_FILTER_DEFAULT_ALLOW``
+and ``KVM_MSR_FILTER_DEFAULT_DENY``.
+
+Each bitmap range specifies a range of MSRs to potentially allow access on.
+The range goes from MSR index [base .. base+nmsrs]. The flags field
+indicates whether reads, writes or both reads and writes are filtered
+by setting a 1 bit in the bitmap for the corresponding MSR index.
+
+If an MSR access is not permitted through the filtering, it generates a
+#GP inside the guest. When combined with KVM_CAP_X86_USER_SPACE_MSR, that
+allows user space to deflect and potentially handle various MSR accesses
+into user space.
+
+If a vCPU is in running state while this ioctl is invoked, the vCPU may
+experience inconsistent filtering behavior on MSR accesses.

-	 * There are multiple assembly passes as the generated code will change

-	 * paths required.
-	 *
-	 * The range of standard conditional branches is +/- 32Kbytes.	Since
-	 * BPF_MAXINSNS = 4096, we can only jump from (worst case) start to
-	 * finish with 8 bytes/instruction.  Not feasible, so long jumps are
-	 * used, distinct from short branches.
-	 *
-	 * Current:
-	 *
-	 * For now, both branch types assemble to 2 words (short branches padded
-	 * with a NOP); this is less efficient, but assembly will always complete
-	 * after exactly 3 passes:
-	 *
-	 * First pass: No code buffer; Program is "faux-generated" -- no code
-	 * emitted but maximum size of output determined (and addrs[] filled
-	 * in).	 Also, we note whether we use M[], whether we use skb data, etc.
-	 * All generation choices assumed to be 'worst-case', e.g. branches all
-	 * far (2 instructions), return path code reduction not available, etc.
-	 *
-	 * Second pass: Code buffer allocated with size determined previously.
-	 * Prologue generated to support features we have seen used.  Exit paths
-	 * determined and addrs[] is filled in again, as code may be slightly
-	 * smaller as a result.
-	 *
-	 * Third pass: Code generated 'for real', and branch destinations
-	 * determined from now-accurate addrs[] map.
-	 *
-	 * Ideal:
-	 *
-	 * If we optimise this, near branches will be shorter.	On the
-	 * first assembly pass, we should err on the side of caution and
-	 * generate the biggest code.  On subsequent passes, branches will be
-	 * generated short or long and code size will reduce.  With smaller
-	 * code, more branches may fall into the short category, and code will
-	 * reduce more.
-	 *
-	 * Finally, if we see one pass generate code the same size as the

+	  store the kernel image depending on your own flash memory usage.

+
+	  SPARSEMEM is required because the kernel text and rodata that are

+ * Add a fault to the device workqueue, to be handled by mm.
+ *
+ * This module doesn't handle PCI PASID Stop Marker; IOMMU drivers must discard
+ * them before reporting faults. A PASID Stop Marker (LRW = 0b100) doesn't
+ * expect a response. It may be generated when disabling a PASID (issuing a
+ * PASID stop request) by some PCI devices.
+ *
+ * The PASID stop request is issued by the device driver before unbind(). Once
+ * it completes, no page request is generated for this PASID anymore and
+ * outstanding ones have been pushed to the IOMMU (as per PCIe 4.0r1.0 - 6.20.1
+ * and 10.4.1.2 - Managing PASID TLP Prefix Usage). Some PCI devices will wait
+ * for all outstanding page requests to come back with a response before
+ * completing the PASID stop request. Others do not wait for page responses, and
+ * instead issue this Stop Marker that tells us when the PASID can be
+ * reallocated.
+ *
+ * It is safe to discard the Stop Marker because it is an optimization.
+ * a. Page requests, which are posted requests, have been flushed to the IOMMU
+ *    when the stop request completes.
+ * b. The IOMMU driver flushes all fault queues on unbind() before freeing the
+ *    PASID.
+ *
+ * So even though the Stop Marker might be issued by the device *after* the stop
+ * request completes, outstanding faults will have been dealt with by the time
+ * the PASID is freed.

+ *    This is an array of lists where the index in the array represents the
+ *    largest free order in the buddy bitmap of the participating group infos of
+ *    that list. So, there are exactly MB_NUM_ORDERS(sb) (which means total
+ *    number of buddy bitmap orders possible) number of lists. Group-infos are
+ *    placed in appropriate lists.
+ *
+ * 2) Average fragment size rb tree (sbi->s_mb_avg_fragment_size_root)
+ *
+ *    Locking: sbi->s_mb_rb_lock (rwlock)
+ *
+ *    This is a red black tree consisting of group infos and the tree is sorted
+ *    by average fragment sizes (which is calculated as ext4_group_info->bb_free
+ *    / ext4_group_info->bb_fragments).
+ *
+ * When "mb_optimize_scan" mount option is set, mballoc consults the above data
+ * structures to decide the order in which groups are to be traversed for
+ * fulfilling an allocation request.
+ *
+ * At CR = 0, we look for groups which have the largest_free_order >= the order
+ * of the request. We directly look at the largest free order list in the data
+ * structure (1) above where largest_free_order = order of the request. If that
+ * list is empty, we look at remaining list in the increasing order of
+ * largest_free_order. This allows us to perform CR = 0 lookup in O(1) time.
+ *
+ * At CR = 1, we only consider groups where average fragment size > request
+ * size. So, we lookup a group which has average fragment size just above or
+ * equal to request size using our rb tree (data structure 2) in O(log N) time.
+ *
+ * If "mb_optimize_scan" mount option is not set, mballoc traverses groups in
+ * linear order which requires O(N) search time for each CR 0 and CR 1 phase.
+ *
  * The regular allocator (using the buddy cache) supports a few tunables.

+ *
+ * A set of actions on kernel objects may be defined by an attribute (e.g.
+ * &struct landlock_path_beneath_attr) including a bitmask of access.
+ *
+ * Filesystem flags
+ * ~~~~~~~~~~~~~~~~
+ *
+ * These flags enable to restrict a sandboxed process to a set of actions on
+ * files and directories.  Files or directories opened before the sandboxing
+ * are not subject to these restrictions.
+ *
+ * A file can only receive these access rights:
+ *
+ * - %LANDLOCK_ACCESS_FS_EXECUTE: Execute a file.
+ * - %LANDLOCK_ACCESS_FS_WRITE_FILE: Open a file with write access.
+ * - %LANDLOCK_ACCESS_FS_READ_FILE: Open a file with read access.
+ *
+ * A directory can receive access rights related to files or directories.  The
+ * following access right is applied to the directory itself, and the
+ * directories beneath it:
+ *
+ * - %LANDLOCK_ACCESS_FS_READ_DIR: Open a directory or list its content.
+ *
+ * However, the following access rights only apply to the content of a
+ * directory, not the directory itself:
+ *
+ * - %LANDLOCK_ACCESS_FS_REMOVE_DIR: Remove an empty directory or rename one.
+ * - %LANDLOCK_ACCESS_FS_REMOVE_FILE: Unlink (or rename) a file.
+ * - %LANDLOCK_ACCESS_FS_MAKE_CHAR: Create (or rename or link) a character
+ *   device.
+ * - %LANDLOCK_ACCESS_FS_MAKE_DIR: Create (or rename) a directory.
+ * - %LANDLOCK_ACCESS_FS_MAKE_REG: Create (or rename or link) a regular file.
+ * - %LANDLOCK_ACCESS_FS_MAKE_SOCK: Create (or rename or link) a UNIX domain
+ *   socket.
+ * - %LANDLOCK_ACCESS_FS_MAKE_FIFO: Create (or rename or link) a named pipe.
+ * - %LANDLOCK_ACCESS_FS_MAKE_BLOCK: Create (or rename or link) a block device.
+ * - %LANDLOCK_ACCESS_FS_MAKE_SYM: Create (or rename or link) a symbolic link.
+ *
+ * .. warning::
+ *
+ *   It is currently not possible to restrict some file-related actions
+ *   accessible through these syscall families: :manpage:`chdir(2)`,
+ *   :manpage:`truncate(2)`, :manpage:`stat(2)`, :manpage:`flock(2)`,
+ *   :manpage:`chmod(2)`, :manpage:`chown(2)`, :manpage:`setxattr(2)`,
+ *   :manpage:`utime(2)`, :manpage:`ioctl(2)`, :manpage:`fcntl(2)`,
+ *   :manpage:`access(2)`.
+ *   Future Landlock evolutions will enable to restrict them.

+config SECURITY_LANDLOCK
+	bool "Landlock support"
+	depends on SECURITY && !ARCH_EPHEMERAL_INODES
+	select SECURITY_PATH
+	help
+	  Landlock is a sandboxing mechanism that enables processes to restrict
+	  themselves (and their future children) by gradually enforcing
+	  tailored access control policies.  A Landlock security policy is a
+	  set of access rights (e.g. open a file in read-only, make a
+	  directory, etc.) tied to a file hierarchy.  Such policy can be
+	  configured and enforced by any processes for themselves using the
+	  dedicated system calls: landlock_create_ruleset(),
+	  landlock_add_rule(), and landlock_restrict_self().
+
+	  See Documentation/userspace-api/landlock.rst for further information.
+
+	  If you are unsure how to answer this question, answer N.  Otherwise,
+	  you should also prepend "landlock," to the content of CONFIG_LSM to
+	  enable Landlock at boot time.

+ * Allocation:
+ *   Messages are initially allocated in the ops->hw_params() after the size and

+ *
+ * Freeing:
+ *   Messages can be safely freed after the queue has been successfully flushed
+ *   (RELEASE command in the ops->sync_stop()) and the ops->hw_free() has been
+ *   called.
+ *
+ *   When the substream stops, the ops->sync_stop() waits until the device has

+ *   signal or due to a timeout. In this case, the device can still access
+ *   messages even after calling ops->hw_free(). It can also issue an interrupt,
+ *   and the interrupt handler will also try to access message structures.
+ *
+ *   Therefore, freeing of already allocated messages occurs:
+ *
+ *   - in ops->hw_params(), if this operator was called several times in a row,
+ *     or if ops->hw_free() failed to free messages previously;

+Intel hybrid support
+--------------------
+Support for Intel hybrid events within perf tools.
+
+For some Intel platforms, such as AlderLake, which is hybrid platform and
+it consists of atom cpu and core cpu. Each cpu has dedicated event list.
+Part of events are available on core cpu, part of events are available
+on atom cpu and even part of events are available on both.
+
+Kernel exports two new cpu pmus via sysfs:
+/sys/devices/cpu_core
+/sys/devices/cpu_atom
+
+The 'cpus' files are created under the directories. For example,
+
+cat /sys/devices/cpu_core/cpus
+0-15
+
+cat /sys/devices/cpu_atom/cpus
+16-23
+
+It indicates cpu0-cpu15 are core cpus and cpu16-cpu23 are atom cpus.
+
+Quickstart
+
+List hybrid event
+-----------------
+
+As before, use perf-list to list the symbolic event.
+
+perf list
+
+inst_retired.any
+	[Fixed Counter: Counts the number of instructions retired. Unit: cpu_atom]
+inst_retired.any
+	[Number of instructions retired. Fixed Counter - architectural event. Unit: cpu_core]
+
+The 'Unit: xxx' is added to brief description to indicate which pmu
+the event is belong to. Same event name but with different pmu can
+be supported.
+
+Enable hybrid event with a specific pmu
+---------------------------------------
+
+To enable a core only event or atom only event, following syntax is supported:
+
+	cpu_core/<event name>/
+or
+	cpu_atom/<event name>/
+
+For example, count the 'cycles' event on core cpus.
+
+	perf stat -e cpu_core/cycles/
+
+Create two events for one hardware event automatically
+------------------------------------------------------
+
+When creating one event and the event is available on both atom and core,
+two events are created automatically. One is for atom, the other is for
+core. Most of hardware events and cache events are available on both
+cpu_core and cpu_atom.
+
+For hardware events, they have pre-defined configs (e.g. 0 for cycles).
+But on hybrid platform, kernel needs to know where the event comes from
+(from atom or from core). The original perf event type PERF_TYPE_HARDWARE
+can't carry pmu information. So now this type is extended to be PMU aware
+type. The PMU type ID is stored at attr.config[63:32].
+
+PMU type ID is retrieved from sysfs.
+/sys/devices/cpu_atom/type
+/sys/devices/cpu_core/type
+
+The new attr.config layout for PERF_TYPE_HARDWARE:
+
+PERF_TYPE_HARDWARE:                 0xEEEEEEEE000000AA
+                                    AA: hardware event ID
+                                    EEEEEEEE: PMU type ID
+
+Cache event is similar. The type PERF_TYPE_HW_CACHE is extended to be
+PMU aware type. The PMU type ID is stored at attr.config[63:32].
+
+The new attr.config layout for PERF_TYPE_HW_CACHE:
+
+PERF_TYPE_HW_CACHE:                 0xEEEEEEEE00DDCCBB
+                                    BB: hardware cache ID
+                                    CC: hardware cache op ID
+                                    DD: hardware cache op result ID
+                                    EEEEEEEE: PMU type ID
+
+When enabling a hardware event without specified pmu, such as,
+perf stat -e cycles -a (use system-wide in this example), two events
+are created automatically.

+
+type 0 is PERF_TYPE_HARDWARE.
+0x4 in 0x400000000 indicates it's cpu_core pmu.
+0x8 in 0x800000000 indicates it's cpu_atom pmu (atom pmu type id is random).
+
+The kernel creates 'cycles' (0x400000000) on cpu0-cpu15 (core cpus),
+and create 'cycles' (0x800000000) on cpu16-cpu23 (atom cpus).
+
+For perf-stat result, it displays two events:
+
+ Performance counter stats for 'system wide':
+
+           6,744,979      cpu_core/cycles/
+           1,965,552      cpu_atom/cycles/
+
+The first 'cycles' is core event, the second 'cycles' is atom event.
+
+Thread mode example:
+--------------------
+
+perf-stat reports the scaled counts for hybrid event and with a percentage
+displayed. The percentage is the event's running time/enabling time.
+
+One example, 'triad_loop' runs on cpu16 (atom core), while we can see the
+scaled value for core cycles is 160,444,092 and the percentage is 0.47%.
+
+perf stat -e cycles -- taskset -c 16 ./triad_loop
+
+As previous, two events are created.

+
+perf-record:
+------------
+
+If there is no '-e' specified in perf record, on hybrid platform,
+it creates two default 'cycles' and adds them to event list. One
+is for core, the other is for atom.
+
+perf-stat:
+----------
+
+If there is no '-e' specified in perf stat, on hybrid platform,
+besides of software events, following events are created and
+added to event list in order.
+
+cpu_core/cycles/,
+cpu_atom/cycles/,
+cpu_core/instructions/,
+cpu_atom/instructions/,
+cpu_core/branches/,
+cpu_atom/branches/,
+cpu_core/branch-misses/,
+cpu_atom/branch-misses/
+
+Of course, both perf-stat and perf-record support to enable
+hybrid event with a specific pmu.
+
+e.g.
+perf stat -e cpu_core/cycles/
+perf stat -e cpu_atom/cycles/
+perf stat -e cpu_core/r1a/
+perf stat -e cpu_atom/L1-icache-loads/
+perf stat -e cpu_core/cycles/,cpu_atom/instructions/
+perf stat -e '{cpu_core/cycles/,cpu_core/instructions/}'
+
+But '{cpu_core/cycles/,cpu_atom/instructions/}' will return
+warning and disable grouping, because the pmus in group are
+not matched (cpu_core vs. cpu_atom).

+NAME
+----
+perf-iostat - Show I/O performance metrics
+
+SYNOPSIS
+--------
+[verse]
+'perf iostat' list
+'perf iostat' <ports> -- <command> [<options>]
+
+DESCRIPTION
+-----------
+Mode is intended to provide four I/O performance metrics per each PCIe root port:
+
+- Inbound Read   - I/O devices below root port read from the host memory, in MB
+
+- Inbound Write  - I/O devices below root port write to the host memory, in MB
+
+- Outbound Read  - CPU reads from I/O devices below root port, in MB
+
+- Outbound Write - CPU writes to I/O devices below root port, in MB
+
+OPTIONS
+-------
+<command>...::
+	Any command you can specify in a shell.
+
+list::
+	List all PCIe root ports.
+
+<ports>::
+	Select the root ports for monitoring. Comma-separated list is supported.
+
+EXAMPLES
+--------
+
+1. List all PCIe root ports (example for 2-S platform):
+
+   $ perf iostat list
+   S0-uncore_iio_0<0000:00>
+   S1-uncore_iio_0<0000:80>
+   S0-uncore_iio_1<0000:17>
+   S1-uncore_iio_1<0000:85>
+   S0-uncore_iio_2<0000:3a>
+   S1-uncore_iio_2<0000:ae>
+   S0-uncore_iio_3<0000:5d>
+   S1-uncore_iio_3<0000:d7>
+
+2. Collect metrics for all PCIe root ports:
+
+   $ perf iostat -- dd if=/dev/zero of=/dev/nvme0n1 bs=1M oflag=direct
+   357708+0 records in
+   357707+0 records out

+ * bperf: share hardware PMCs with BPF
+ *
+ * perf uses performance monitoring counters (PMC) to monitor system
+ * performance. The PMCs are limited hardware resources. For example,
+ * Intel CPUs have 3x fixed PMCs and 4x programmable PMCs per cpu.
+ *
+ * Modern data center systems use these PMCs in many different ways:
+ * system level monitoring, (maybe nested) container level monitoring, per
+ * process monitoring, profiling (in sample mode), etc. In some cases,
+ * there are more active perf_events than available hardware PMCs. To allow
+ * all perf_events to have a chance to run, it is necessary to do expensive
+ * time multiplexing of events.
+ *
+ * On the other hand, many monitoring tools count the common metrics
+ * (cycles, instructions). It is a waste to have multiple tools create
+ * multiple perf_events of "cycles" and occupy multiple PMCs.
+ *
+ * bperf tries to reduce such wastes by allowing multiple perf_events of
+ * "cycles" or "instructions" (at different scopes) to share PMUs. Instead
+ * of having each perf-stat session to read its own perf_events, bperf uses
+ * BPF programs to read the perf_events and aggregate readings to BPF maps.
+ * Then, the perf-stat session(s) reads the values from these BPF maps.

+ *
+ * The figure above shows the architecture of bperf. Note that the figure
+ * is divided into 3 regions: shared progs and maps (top left), per session
+ * progs and maps (top right), and user space (bottom).
+ *
+ * The leader prog is triggered on each context switch (cs). The leader
+ * prog reads perf_events and stores the difference (current_reading -
+ * previous_reading) to the diff map. For the same metric, e.g. "cycles",
+ * multiple perf-stat sessions share the same leader prog.
+ *
+ * Each perf-stat session creates a follower prog as fexit program to the
+ * leader prog. It is possible to attach up to BPF_MAX_TRAMP_PROGS (38)
+ * follower progs to the same leader prog. The follower prog checks current
+ * task and processor ID to decide whether to add the value from the diff
+ * map to its accumulated reading map (accum_readings).
+ *
+ * Finally, perf-stat user space reads the value from accum_reading map.
+ *
+ * Besides context switch, it is also necessary to trigger the leader prog
+ * before perf-stat reads the value. Otherwise, the accum_reading map may
+ * not have the latest reading from the perf_events. This is achieved by
+ * triggering the event via sys_bpf(BPF_PROG_TEST_RUN) to each CPU.
+ *
+ * Comment before the definition of struct perf_event_attr_map_entry
+ * describes how different sessions of perf-stat share information about
+ * the leader prog.

The cpu-set is ordered from low to high, comma delimited with ".." and "-" permitted to denote a range. eg. 1,2,8,14..17,21-44
