+
+ The selinuxfs "user" node allows userspace to request a list

+

+thus should be free of any problems that show up in -next, but not in Linus'
+tree.
+
+This will bisect across a wide range of changes, some of which you might have
+used in earlier linux-next releases without problems. Sadly there is no simple
+way to avoid checking them: bisecting from one linux-next release to a later
+one (say between 'next-20241020' and 'next-20241021') is impossible, as they

+hardware to allow a VM guest to be run in a way which protects the code
+and data of the guest from the hypervisor. It extends the older "two
+world" model (Normal and Secure World) into four worlds: Normal, Secure,
+Root and Realm. Linux can then also be run as a guest to a monitor
+running in the Realm world.
+
+The monitor running in the Realm world is known as the Realm Management
+Monitor (RMM) and implements the Realm Management Monitor
+specification[1]. The monitor acts a bit like a hypervisor (e.g. it runs
+in EL2 and manages the stage 2 page tables etc of the guests running in
+Realm world), however much of the control is handled by a hypervisor
+running in the Normal World. The Normal World hypervisor uses the Realm
+Management Interface (RMI) defined by the RMM specification to request
+the RMM to perform operations (e.g. mapping memory or executing a vCPU).
+
+The RMM defines an environment for guests where the address space (IPA)
+is split into two. The lower half is protected - any memory that is
+mapped in this half cannot be seen by the Normal World and the RMM
+restricts what operations the Normal World can perform on this memory
+(e.g. the Normal World cannot replace pages in this region without the
+guest's cooperation). The upper half is shared, the Normal World is free
+to make changes to the pages in this region, and is able to emulate MMIO
+devices in this region too.
+
+A guest running in a Realm may also communicate with the RMM using the
+Realm Services Interface (RSI) to request changes in its environment or
+to perform attestation about its environment. In particular it may
+request that areas of the protected address space are transitioned
+between 'RAM' and 'EMPTY' (in either direction). This allows a Realm
+guest to give up memory to be returned to the Normal World, or to
+request new memory from the Normal World. Without an explicit request
+from the Realm guest the RMM will otherwise prevent the Normal World
+from making these changes.
+
+Linux as a Realm Guest
+----------------------
+
+To run Linux as a guest within a Realm, the following must be provided
+either by the VMM or by a `boot loader` run in the Realm before Linux:
+
+ * All protected RAM described to Linux (by DT or ACPI) must be marked
+ RIPAS RAM before handing control over to Linux.
+
+ * MMIO devices must be either unprotected (e.g. emulated by the Normal
+ World) or marked RIPAS DEV.
+
+ * MMIO devices emulated by the Normal World and used very early in boot
+ (specifically earlycon) must be specified in the upper half of IPA.
+ For earlycon this can be done by specifying the address on the
+ command line, e.g. with an IPA size of 33 bits and the base address
+ of the emulated UART at 0x1000000: ``earlycon=uart,mmio,0x101000000``
+
+ * Linux will use bounce buffers for communicating with unprotected
+ devices. It will transition some protected memory to RIPAS EMPTY and
+ expect to be able to access unprotected pages at the same IPA address
+ but with the highest valid IPA bit set. The expectation is that the
+ VMM will remove the physical pages from the protected mapping and
+ provide those pages as unprotected pages.

+===============================================
+Guarded Control Stack support for AArch64 Linux
+===============================================
+
+This document outlines briefly the interface provided to userspace by Linux in
+order to support use of the ARM Guarded Control Stack (GCS) feature.
+
+This is an outline of the most important features and issues only and not
+intended to be exhaustive.
+
+
+
+1. General
+-----------
+
+* GCS is an architecture feature intended to provide greater protection
+ against return oriented programming (ROP) attacks and to simplify the
+ implementation of features that need to collect stack traces such as
+ profiling.
+
+* When GCS is enabled a separate guarded control stack is maintained by the
+ PE which is writeable only through specific GCS operations. This
+ stores the call stack only, when a procedure call instruction is
+ performed the current PC is pushed onto the GCS and on RET the
+ address in the LR is verified against that on the top of the GCS.
+
+* When active the current GCS pointer is stored in the system register
+ GCSPR_EL0. This is readable by userspace but can only be updated
+ via specific GCS instructions.
+
+* The architecture provides instructions for switching between guarded
+ control stacks with checks to ensure that the new stack is a valid
+ target for switching.
+
+* The functionality of GCS is similar to that provided by the x86 Shadow
+ Stack feature, due to sharing of userspace interfaces the ABI refers to
+ shadow stacks rather than GCS.
+
+* Support for GCS is reported to userspace via HWCAP_GCS in the aux vector
+ AT_HWCAP2 entry.
+
+* GCS is enabled per thread. While there is support for disabling GCS
+ at runtime this should be done with great care.
+
+* GCS memory access faults are reported as normal memory access faults.
+
+* GCS specific errors (those reported with EC 0x2d) will be reported as
+ SIGSEGV with a si_code of SEGV_CPERR (control protection error).
+
+* GCS is supported only for AArch64.
+
+* On systems where GCS is supported GCSPR_EL0 is always readable by EL0
+ regardless of the GCS configuration for the thread.
+
+* The architecture supports enabling GCS without verifying that return values
+ in LR match those in the GCS, the LR will be ignored. This is not supported
+ by Linux.
+
+
+
+2. Enabling and disabling Guarded Control Stacks
+-------------------------------------------------
+
+* GCS is enabled and disabled for a thread via the PR_SET_SHADOW_STACK_STATUS
+ prctl(), this takes a single flags argument specifying which GCS features
+ should be used.
+
+* When set PR_SHADOW_STACK_ENABLE flag allocates a Guarded Control Stack
+ and enables GCS for the thread, enabling the functionality controlled by
+ GCSCRE0_EL1.{nTR, RVCHKEN, PCRSEL}.
+
+* When set the PR_SHADOW_STACK_PUSH flag enables the functionality controlled
+ by GCSCRE0_EL1.PUSHMEn, allowing explicit GCS pushes.
+
+* When set the PR_SHADOW_STACK_WRITE flag enables the functionality controlled
+ by GCSCRE0_EL1.STREn, allowing explicit stores to the Guarded Control Stack.
+
+* Any unknown flags will cause PR_SET_SHADOW_STACK_STATUS to return -EINVAL.
+
+* PR_LOCK_SHADOW_STACK_STATUS is passed a bitmask of features with the same
+ values as used for PR_SET_SHADOW_STACK_STATUS. Any future changes to the
+ status of the specified GCS mode bits will be rejected.
+
+* PR_LOCK_SHADOW_STACK_STATUS allows any bit to be locked, this allows
+ userspace to prevent changes to any future features.
+
+* There is no support for a process to remove a lock that has been set for
+ it.
+
+* PR_SET_SHADOW_STACK_STATUS and PR_LOCK_SHADOW_STACK_STATUS affect only the
+ thread that called them, any other running threads will be unaffected.
+
+* New threads inherit the GCS configuration of the thread that created them.
+
+* GCS is disabled on exec().
+
+* The current GCS configuration for a thread may be read with the
+ PR_GET_SHADOW_STACK_STATUS prctl(), this returns the same flags that
+ are passed to PR_SET_SHADOW_STACK_STATUS.
+
+* If GCS is disabled for a thread after having previously been enabled then
+ the stack will remain allocated for the lifetime of the thread. At present
+ any attempt to reenable GCS for the thread will be rejected, this may be
+ revisited in future.
+
+* It should be noted that since enabling GCS will result in GCS becoming
+ active immediately it is not normally possible to return from the function
+ that invoked the prctl() that enabled GCS. It is expected that the normal
+ usage will be that GCS is enabled very early in execution of a program.
+
+
+
+3. Allocation of Guarded Control Stacks
+----------------------------------------
+
+* When GCS is enabled for a thread a new Guarded Control Stack will be
+ allocated for it of half the standard stack size or 2 gigabytes,
+ whichever is smaller.
+
+* When a new thread is created by a thread which has GCS enabled then a
+ new Guarded Control Stack will be allocated for the new thread with
+ half the size of the standard stack.
+
+* When a stack is allocated by enabling GCS or during thread creation then
+ the top 8 bytes of the stack will be initialised to 0 and GCSPR_EL0 will
+ be set to point to the address of this 0 value, this can be used to
+ detect the top of the stack.
+
+* Additional Guarded Control Stacks can be allocated using the
+ map_shadow_stack() system call.
+
+* Stacks allocated using map_shadow_stack() can optionally have an end of
+ stack marker and cap placed at the top of the stack. If the flag
+ SHADOW_STACK_SET_TOKEN is specified a cap will be placed on the stack,
+ if SHADOW_STACK_SET_MARKER is not specified the cap will be the top 8
+ bytes of the stack and if it is specified then the cap will be the next
+ 8 bytes. While specifying just SHADOW_STACK_SET_MARKER by itself is
+ valid since the marker is all bits 0 it has no observable effect.
+
+* Stacks allocated using map_shadow_stack() must have a size which is a
+ multiple of 8 bytes larger than 8 bytes and must be 8 bytes aligned.
+
+* An address can be specified to map_shadow_stack(), if one is provided then
+ it must be aligned to a page boundary.
+
+* When a thread is freed the Guarded Control Stack initially allocated for
+ that thread will be freed. Note carefully that if the stack has been
+ switched this may not be the stack currently in use by the thread.
+
+
+4. Signal handling
+--------------------
+
+* A new signal frame record gcs_context encodes the current GCS mode and
+ pointer for the interrupted context on signal delivery. This will always
+ be present on systems that support GCS.
+
+* The record contains a flag field which reports the current GCS configuration
+ for the interrupted context as PR_GET_SHADOW_STACK_STATUS would.
+
+* The signal handler is run with the same GCS configuration as the interrupted
+ context.
+
+* When GCS is enabled for the interrupted thread a signal handling specific
+ GCS cap token will be written to the GCS, this is an architectural GCS cap
+ with the token type (bits 0..11) all clear. The GCSPR_EL0 reported in the
+ signal frame will point to this cap token.
+
+* The signal handler will use the same GCS as the interrupted context.
+
+* When GCS is enabled on signal entry a frame with the address of the signal
+ return handler will be pushed onto the GCS, allowing return from the signal
+ handler via RET as normal. This will not be reported in the gcs_context in
+ the signal frame.
+
+
+5. Signal return
+-----------------
+
+When returning from a signal handler:
+
+* If there is a gcs_context record in the signal frame then the GCS flags
+ and GCSPR_EL0 will be restored from that context prior to further
+ validation.
+
+* If there is no gcs_context record in the signal frame then the GCS
+ configuration will be unchanged.
+
+* If GCS is enabled on return from a signal handler then GCSPR_EL0 must
+ point to a valid GCS signal cap record, this will be popped from the
+ GCS prior to signal return.
+
+* If the GCS configuration is locked when returning from a signal then any
+ attempt to change the GCS configuration will be treated as an error. This
+ is true even if GCS was not enabled prior to signal entry.
+
+* GCS may be disabled via signal return but any attempt to enable GCS via
+ signal return will be rejected.
+
+
+6. ptrace extensions
+---------------------
+
+* A new regset NT_ARM_GCS is defined for use with PTRACE_GETREGSET and
+ PTRACE_SETREGSET.
+
+* The GCS mode, including enable and disable, may be configured via ptrace.
+ If GCS is enabled via ptrace no new GCS will be allocated for the thread.
+
+* Configuration via ptrace ignores locking of GCS mode bits.
+
+
+7. ELF coredump extensions
+---------------------------
+
+* NT_ARM_GCS notes will be added to each coredump for each thread of the
+ dumped process. The contents will be equivalent to the data that would
+ have been read if a PTRACE_GETREGSET of the corresponding type were
+ executed for each thread when the coredump was generated.
+
+
+
+8. /proc extensions
+--------------------
+
+* Guarded Control Stack pages will include "ss" in their VmFlags in
+ /proc/<pid>/smaps.

+Memory copy/set instructions (MOPS)
+===================================
+
+A MOPS memory copy/set operation consists of three consecutive CPY* or SET*
+instructions: a prologue, main and epilogue (for example: CPYP, CPYM, CPYE).
+
+A main or epilogue instruction can take a MOPS exception for various reasons,
+for example when a task is migrated to a CPU with a different MOPS
+implementation, or when the instruction's alignment and size requirements are
+not met. The software exception handler is then expected to reset the registers
+and restart execution from the prologue instruction. Normally this is handled
+by the kernel.
+
+For more details refer to "D1.3.5.7 Memory Copy and Memory Set exceptions" in
+the Arm Architecture Reference Manual DDI 0487K.a (Arm ARM).
+
+.. _arm64_mops_hyp:
+
+Hypervisor requirements
+-----------------------
+
+A hypervisor running a Linux guest must handle all MOPS exceptions from the
+guest kernel, as Linux may not be able to handle the exception at all times.
+For example, a MOPS exception can be taken when the hypervisor migrates a vCPU
+to another physical CPU with a different MOPS implementation.
+
+To do this, the hypervisor must:
+
+ - Set HCRX_EL2.MCE2 to 1 so that the exception is taken to the hypervisor.
+
+ - Have an exception handler that implements the algorithm from the Arm ARM
+ rules CNTMJ and MWFQH.
+
+ - Set the guest's PSTATE.SS to 0 in the exception handler, to handle a
+ potential step of the current instruction.
+
+ Note: Clearing PSTATE.SS is needed so that a single step exception is taken
+ on the next instruction (the prologue instruction). Otherwise prologue
+ would get silently stepped over and the single step exception taken on the
+ main instruction. Note that if the guest instruction is not being stepped
+ then clearing PSTATE.SS has no effect.

+Folio Queue
+===========
+

+
+ * Overview
+ * Initialisation
+ * Adding and removing folios
+ * Querying information about a folio

+ * Folio queue iteration
+ * Folio marks
+ * Lockless simultaneous production/consumption issues
+
+
+Overview
+========
+
+The folio_queue struct forms a single segment in a segmented list of folios
+that can be used to form an I/O buffer. As such, the list can be iterated over
+using the ITER_FOLIOQ iov_iter type.
+
+The publicly accessible members of the structure are::
+
+ struct folio_queue {
+ struct folio_queue *next;
+ struct folio_queue *prev;
+ ...
+ };
+
+A pair of pointers are provided, ``next`` and ``prev``, that point to the
+segments on either side of the segment being accessed. Whilst this is a
+doubly-linked list, it is intentionally not a circular list; the outward
+sibling pointers in terminal segments should be NULL.
+
+Each segment in the list also stores:
+
+ * an ordered sequence of folio pointers,
+ * the size of each folio and
+ * three 1-bit marks per folio,
+
+but hese should not be accessed directly as the underlying data structure may
+change, but rather the access functions outlined below should be used.
+
+The facility can be made accessible by::
+
+ #include <linux/folio_queue.h>
+
+and to use the iterator::
+
+ #include <linux/uio.h>
+
+
+Initialisation
+==============
+
+A segment should be initialised by calling::
+
+ void folioq_init(struct folio_queue *folioq);
+
+with a pointer to the segment to be initialised. Note that this will not
+necessarily initialise all the folio pointers, so care must be taken to check
+the number of folios added.
+
+
+Adding and removing folios
+==========================
+
+Folios can be set in the next unused slot in a segment struct by calling one
+of::
+
+ unsigned int folioq_append(struct folio_queue *folioq,
+ struct folio *folio);
+
+ unsigned int folioq_append_mark(struct folio_queue *folioq,
+ struct folio *folio);
+
+Both functions update the stored folio count, store the folio and note its
+size. The second function also sets the first mark for the folio added. Both
+functions return the number of the slot used. [!] Note that no attempt is made
+to check that the capacity wasn't overrun and the list will not be extended
+automatically.
+
+A folio can be excised by calling::
+
+ void folioq_clear(struct folio_queue *folioq, unsigned int slot);
+
+This clears the slot in the array and also clears all the marks for that folio,
+but doesn't change the folio count - so future accesses of that slot must check
+if the slot is occupied.
+
+
+Querying information about a folio
+==================================
+
+Information about the folio in a particular slot may be queried by the
+following function::
+
+ struct folio *folioq_folio(const struct folio_queue *folioq,
+ unsigned int slot);
+
+If a folio has not yet been set in that slot, this may yield an undefined
+pointer. The size of the folio in a slot may be queried with either of::
+
+ unsigned int folioq_folio_order(const struct folio_queue *folioq,
+ unsigned int slot);
+
+ size_t folioq_folio_size(const struct folio_queue *folioq,
+ unsigned int slot);
+
+The first function returns the size as an order and the second as a number of
+bytes.
+
+
+Querying information about a folio_queue
+========================================
+
+Information may be retrieved about a particular segment with the following
+functions::
+
+ unsigned int folioq_nr_slots(const struct folio_queue *folioq);
+
+ unsigned int folioq_count(struct folio_queue *folioq);
+
+ bool folioq_full(struct folio_queue *folioq);
+
+The first function returns the maximum capacity of a segment. It must not be
+assumed that this won't vary between segments. The second returns the number
+of folios added to a segments and the third is a shorthand to indicate if the
+segment has been filled to capacity.
+
+Not that the count and fullness are not affected by clearing folios from the
+segment. These are more about indicating how many slots in the array have been
+initialised, and it assumed that slots won't get reused, but rather the segment
+will get discarded as the queue is consumed.
+
+
+Folio marks
+===========
+
+Folios within a queue can also have marks assigned to them. These marks can be
+used to note information such as if a folio needs folio_put() calling upon it.
+There are three marks available to be set for each folio.
+
+The marks can be set by::
+
+ void folioq_mark(struct folio_queue *folioq, unsigned int slot);
+ void folioq_mark2(struct folio_queue *folioq, unsigned int slot);
+ void folioq_mark3(struct folio_queue *folioq, unsigned int slot);
+
+Cleared by::
+
+ void folioq_unmark(struct folio_queue *folioq, unsigned int slot);
+ void folioq_unmark2(struct folio_queue *folioq, unsigned int slot);
+ void folioq_unmark3(struct folio_queue *folioq, unsigned int slot);
+
+And the marks can be queried by::
+
+ bool folioq_is_marked(const struct folio_queue *folioq, unsigned int slot);
+ bool folioq_is_marked2(const struct folio_queue *folioq, unsigned int slot);
+ bool folioq_is_marked3(const struct folio_queue *folioq, unsigned int slot);
+
+The marks can be used for any purpose and are not interpreted by this API.
+
+
+Folio queue iteration
+=====================
+
+A list of segments may be iterated over using the I/O iterator facility using
+an ``iov_iter`` iterator of ``ITER_FOLIOQ`` type. The iterator may be
+initialised with::
+
+ void iov_iter_folio_queue(struct iov_iter *i, unsigned int direction,
+ const struct folio_queue *folioq,
+ unsigned int first_slot, unsigned int offset,
+ size_t count);
+
+This may be told to start at a particular segment, slot and offset within a
+queue. The iov iterator functions will follow the next pointers when advancing
+and prev pointers when reverting when needed.
+
+
+Lockless simultaneous production/consumption issues
+===================================================
+
+If properly managed, the list can be extended by the producer at the head end
+and shortened by the consumer at the tail end simultaneously without the need
+to take locks. The ITER_FOLIOQ iterator inserts appropriate barriers to aid
+with this.
+
+Care must be taken when simultaneously producing and consuming a list. If the
+last segment is reached and the folios it refers to are entirely consumed by
+the IOV iterators, an iov_iter struct will be left pointing to the last segment
+with a slot number equal to the capacity of that segment. The iterator will
+try to continue on from this if there's another segment available when it is
+used again, but care must be taken lest the segment got removed and freed by
+the consumer before the iterator was advanced.
+
+It is recommended that the queue always contain at least one segment, even if
+that segment has never been filled or is entirely spent. This prevents the
+head and tail pointers from collapsing.

-------------------
KMSAN associates a metadata byte (also called shadow byte) with every byte of
-kernel memory. A bit in the shadow byte is set iff the corresponding bit of the
+kernel memory. A bit in the shadow byte is set if the corresponding bit of the
kernel memory byte is uninitialized. Marking the memory uninitialized (i.e.
setting its shadow bytes to ``0xff``) is called poisoning, marking it
initialized (setting the shadow bytes to ``0x00``) is called unpoisoning.

+=============================
+Device testing with kselftest
+=============================
+
+
+There are a few different kselftests available for testing devices generically,
+with some overlap in coverage and different requirements. This document aims to
+give an overview of each one.
+
+Note: Paths in this document are relative to the kselftest folder
+(``tools/testing/selftests``).
+
+Device oriented kselftests:
+
+* Devicetree (``dt``)
+
+ * **Coverage**: Probe status for devices described in Devicetree
+ * **Requirements**: None
+
+* Error logs (``devices/error_logs``)
+
+ * **Coverage**: Error (or more critical) log messages presence coming from any
+ device
+ * **Requirements**: None
+
+* Discoverable bus (``devices/probe``)
+
+ * **Coverage**: Presence and probe status of USB or PCI devices that have been
+ described in the reference file
+ * **Requirements**: Manually describe the devices that should be tested in a
+ YAML reference file (see ``devices/probe/boards/google,spherion.yaml`` for
+ an example)
+
+* Exist (``devices/exist``)
+
+ * **Coverage**: Presence of all devices
+ * **Requirements**: Generate the reference (see ``devices/exist/README.rst``
+ for details) on a known-good kernel
+
+Therefore, the suggestion is to enable the error log and devicetree tests on all
+(DT-based) platforms, since they don't have any requirements. Then to greatly
+improve coverage, generate the reference for each platform and enable the exist
+test. The discoverable bus test can be used to verify the probe status of
+specific USB or PCI devices, but is probably not worth it for most cases.

-0.725 * (1 + R1/R2) V. The ldo3 regulator is fixed to 1.8 V. The ldo1 standby
-regulator can not be disabled and thus should have the regulator-always-on
-property set.

-Required properties:
-- compatible: Should be "brcm,bcm2835-aux-spi".
-- reg: Should contain register location and length for the spi block
-- interrupts: Should contain shared interrupt of the aux block
-- clocks: The clock feeding the SPI controller - needs to

+=====================
+Multigrain Timestamps
+=====================
+
+Introduction
+============
+Historically, the kernel has always used coarse time values to stamp inodes.
+This value is updated every jiffy, so any change that happens within that jiffy
+will end up with the same timestamp.
+
+When the kernel goes to stamp an inode (due to a read or write), it first gets
+the current time and then compares it to the existing timestamp(s) to see
+whether anything will change. If nothing changed, then it can avoid updating
+the inode's metadata.
+
+Coarse timestamps are therefore good from a performance standpoint, since they
+reduce the need for metadata updates, but bad from the standpoint of
+determining whether anything has changed, since a lot of things can happen in a
+jiffy.
+
+They are particularly troublesome with NFSv3, where unchanging timestamps can
+make it difficult to tell whether to invalidate caches. NFSv4 provides a
+dedicated change attribute that should always show a visible change, but not
+all filesystems implement this properly, causing the NFS server to substitute
+the ctime in many cases.
+
+Multigrain timestamps aim to remedy this by selectively using fine-grained
+timestamps when a file has had its timestamps queried recently, and the current
+coarse-grained time does not cause a change.
+
+Inode Timestamps
+================
+There are currently 3 timestamps in the inode that are updated to the current
+wallclock time on different activity:
+
+ctime:
+ The inode change time. This is stamped with the current time whenever
+ the inode's metadata is changed. Note that this value is not settable
+ from userland.
+
+mtime:
+ The inode modification time. This is stamped with the current time
+ any time a file's contents change.
+
+atime:
+ The inode access time. This is stamped whenever an inode's contents are
+ read. Widely considered to be a terrible mistake. Usually avoided with
+ options like noatime or relatime.
+
+Updating the mtime always implies a change to the ctime, but updating the
+atime due to a read request does not.
+
+Multigrain timestamps are only tracked for the ctime and the mtime. atimes are
+not affected and always use the coarse-grained value (subject to the floor).
+
+Inode Timestamp Ordering
+========================
+
+In addition to just providing info about changes to individual files, file
+timestamps also serve an important purpose in applications like "make". These
+programs measure timestamps in order to determine whether source files might be
+newer than cached objects.
+
+Userland applications like make can only determine ordering based on
+operational boundaries. For a syscall those are the syscall entry and exit
+points. For io_uring or nfsd operations, that's the request submission and
+response. In the case of concurrent operations, userland can make no
+determination about the order in which things will occur.
+
+For instance, if a single thread modifies one file, and then another file in
+sequence, the second file must show an equal or later mtime than the first. The
+same is true if two threads are issuing similar operations that do not overlap
+in time.
+
+If however, two threads have racing syscalls that overlap in time, then there
+is no such guarantee, and the second file may appear to have been modified
+before, after or at the same time as the first, regardless of which one was
+submitted first.
+
+Note that the above assumes that the system doesn't experience a backward jump
+of the realtime clock. If that occurs at an inopportune time, then timestamps
+can appear to go backward, even on a properly functioning system.
+
+Multigrain Timestamp Implementation
+===================================
+Multigrain timestamps are aimed at ensuring that changes to a single file are
+always recognizable, without violating the ordering guarantees when multiple
+different files are modified. This affects the mtime and the ctime, but the
+atime will always use coarse-grained timestamps.
+
+It uses an unused bit in the i_ctime_nsec field to indicate whether the mtime
+or ctime has been queried. If either or both have, then the kernel takes
+special care to ensure the next timestamp update will display a visible change.
+This ensures tight cache coherency for use-cases like NFS, without sacrificing
+the benefits of reduced metadata updates when files aren't being watched.
+
+The Ctime Floor Value
+=====================
+It's not sufficient to simply use fine or coarse-grained timestamps based on
+whether the mtime or ctime has been queried. A file could get a fine grained
+timestamp, and then a second file modified later could get a coarse-grained one
+that appears earlier than the first, which would break the kernel's timestamp
+ordering guarantees.
+
+To mitigate this problem, maintain a global floor value that ensures that
+this can't happen. The two files in the above example may appear to have been
+modified at the same time in such a case, but they will never show the reverse
+order. To avoid problems with realtime clock jumps, the floor is managed as a
+monotonic ktime_t, and the values are converted to realtime clock values as
+needed.
+
+Implementation Notes
+====================
+Multigrain timestamps are intended for use by local filesystems that get
+ctime values from the local clock. This is in contrast to network filesystems
+and the like that just mirror timestamp values from a server.
+
+For most filesystems, it's sufficient to just set the FS_MGTIME flag in the
+fstype->fs_flags in order to opt-in, providing the ctime is only ever set via
+inode_set_ctime_current(). If the filesystem has a ->getattr routine that
+doesn't call generic_fillattr, then it should call fill_mg_cmtime() to
+fill those values. For setattr, it should use setattr_copy() to update the
+timestamps, or otherwise mimic its behavior.

+Enforcement for Unacceptable Behavior Code of Conduct Violations
+----------------------------------------------------------------
+
+The Code of Conduct committee works to ensure that our community continues
+to be inclusive and fosters diverse discussions and viewpoints, and works
+to improve those characteristics over time. A majority of the reports the
+Code of Conduct Committee receives stem from incorrect understanding regarding
+the development process and maintainers' roles, responsibilities, and their
+right to make decisions on code acceptance. These are resolved through
+clarification of the development process and the scope of the Code of Conduct.
+
+Unacceptable behaviors could interrupt respectful collaboration for a short
+period of time and negatively impact the health of the community longer term.
+Unacceptable behaviors often get resolved when individuals acknowledge their
+behavior and make amends for it in the setting the violation has taken place.
+
+The Code of Conduct Committee receives reports about unacceptable behaviors
+when they don't get resolved through community discussions. The Code of
+Conduct committee takes measures to restore productive and respectful
+collaboration when an unacceptable behavior has negatively impacted that
+relationship.
+
+The Code of Conduct Committee has the obligation to keep the reports and
+reporters' information private. Reports could come from injured parties
+and community members who are observers of unacceptable behaviors. The
+Code of Conduct Committee has the responsibility to investigate and resolve
+these reports, working with all involved parties.
+
+The Code of Conduct Committee works with the individual to bring about
+change in their understanding of the importance to repair the damage caused
+by their behavior to the injured party and the long term negative impact
+on the community.
+
+The goal is to reach a resolution which is agreeable to all parties. If
+working with the individual fails to bring about the desired outcome, the
+Code of Conduct Committee will evaluate other measures such as seeking
+public apology to repair the damage.
+
+Seek public apology for the violation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Code of Conduct Committee publicly calls out the behavior in the
+setting in which the violation has taken place, seeking public apology
+for the violation.

+ Committee could require public apology as a condition for lifting the

+
+The scope of the ban for a period of time could include:
+
+ a. denying patch contributions and pull requests
+ b. pausing collaboration with the violator by ignoring their
+ contributions and/or blocking their email account(s)
+ c. restricting their ability to communicate via kernel.org platforms,
+ such as mailing lists and social media sites
+
+Once the TAB approves one or more of the measures outlined in the scope of
+the ban by a two-thirds vote, the Code of Conduct Committee will enforce
+the TAB approved measure(s) in collaboration with the community, maintainers,
+sub-maintainers, and kernel.org administrators.
+
+The Code of Conduct Committee is mindful of the negative impact of seeking
+public apology and instituting ban could have on individuals. It is also
+mindful of the longer term harm to the community that could result from
+not taking action when such serious public violations occur.
+
+The effectiveness of the remedial measure(s) approved by the TAB depends
+on the trust and cooperation from the community, maintainers, sub-maintainers,
+and kernel.org administrators in enforcing them.
+
+The Code of Conduct Committee sincerely hopes that unacceptable behaviors
+that require seeking public apologies continue to be exceedingly rare
+occurrences in the future.

+Delay and sleep mechanisms
+==========================
+
+This document seeks to answer the common question: "What is the
+RightWay (TM) to insert a delay?"
+
+This question is most often faced by driver writers who have to
+deal with hardware delays and who may not be the most intimately
+familiar with the inner workings of the Linux Kernel.
+
+The following table gives a rough overview about the existing function
+'families' and their limitations. This overview table does not replace the
+reading of the function description before usage!
+
+.. list-table::

+ - no
+
+A generic advice for non atomic contexts could be:
+
+#. Use `fsleep()` whenever unsure (as it combines all the advantages of the
+ others)
+#. Use `*sleep()` whenever possible
+#. Use `usleep_range*()` whenever accuracy of `*sleep()` is not sufficient
+#. Use `*delay()` for very, very short delays
+
+Find some more detailed information about the function 'families' in the next
+sections.
+
+`*delay()` family of functions
+------------------------------
+
+These functions use the jiffy estimation of clock speed and will busy wait for
+enough loop cycles to achieve the desired delay. udelay() is the basic
+implementation and ndelay() as well as mdelay() are variants.
+
+These functions are mainly used to add a delay in atomic context. Please make
+sure to ask yourself before adding a delay in atomic context: Is this really
+required?
+
+.. kernel-doc:: include/asm-generic/delay.h
+ :identifiers: udelay ndelay
+
+.. kernel-doc:: include/linux/delay.h
+ :identifiers: mdelay
+
+
+`usleep_range*()` and `*sleep()` family of functions
+----------------------------------------------------
+
+These functions use hrtimers or timer list timers to provide the requested
+sleeping duration. In order to decide which function is the right one to use,
+take some basic information into account:
+
+#. hrtimers are more expensive as they are using an rb-tree (instead of hashing)
+#. hrtimers are more expensive when the requested sleeping duration is the first
+ timer which means real hardware has to be programmed
+#. timer list timers always provide some sort of slack as they are jiffy based
+
+The generic advice is repeated here:
+
+#. Use `fsleep()` whenever unsure (as it combines all the advantages of the
+ others)
+#. Use `*sleep()` whenever possible
+#. Use `usleep_range*()` whenever accuracy of `*sleep()` is not sufficient
+
+First check fsleep() function description and to learn more about accuracy,
+please check msleep() function description.

-delays - Information on the various kernel delay / sleep mechanisms
-===================================================================
-
-This document seeks to answer the common question: "What is the
-RightWay (TM) to insert a delay?"
-
-This question is most often faced by driver writers who have to
-deal with hardware delays and who may not be the most intimately
-familiar with the inner workings of the Linux Kernel.
-
-
-Inserting Delays
-----------------
-
-The first, and most important, question you need to ask is "Is my
-code in an atomic context?" This should be followed closely by "Does
-it really need to delay in atomic context?" If so...
-
-ATOMIC CONTEXT:
- You must use the `*delay` family of functions. These
- functions use the jiffy estimation of clock speed
- and will busy wait for enough loop cycles to achieve
- the desired delay:
-
- ndelay(unsigned long nsecs)
- udelay(unsigned long usecs)
- mdelay(unsigned long msecs)
-
- udelay is the generally preferred API; ndelay-level
- precision may not actually exist on many non-PC devices.
-
- mdelay is macro wrapper around udelay, to account for
- possible overflow when passing large arguments to udelay.
- In general, use of mdelay is discouraged and code should
- be refactored to allow for the use of msleep.
-
-NON-ATOMIC CONTEXT:
- You should use the `*sleep[_range]` family of functions.
- There are a few more options here, while any of them may
- work correctly, using the "right" sleep function will
- help the scheduler, power management, and just make your
- driver better :)
-
- -- Backed by busy-wait loop:
-
- udelay(unsigned long usecs)
-
- -- Backed by hrtimers:
-
- usleep_range(unsigned long min, unsigned long max)
-
- -- Backed by jiffies / legacy_timers
-
- msleep(unsigned long msecs)
- msleep_interruptible(unsigned long msecs)
-
- Unlike the `*delay` family, the underlying mechanism
- driving each of these calls varies, thus there are
- quirks you should be aware of.
-
-
- SLEEPING FOR "A FEW" USECS ( < ~10us? ):
- * Use udelay
-
- - Why not usleep?
- On slower systems, (embedded, OR perhaps a speed-
- stepped PC!) the overhead of setting up the hrtimers
- for usleep *may* not be worth it. Such an evaluation
- will obviously depend on your specific situation, but
- it is something to be aware of.
-
- SLEEPING FOR ~USECS OR SMALL MSECS ( 10us - 20ms):
- * Use usleep_range
-
- - Why not msleep for (1ms - 20ms)?
- Explained originally here:
- https://lore.kernel.org/r/15327.1186166232@lwn.net
-
- msleep(1~20) may not do what the caller intends, and
- will often sleep longer (~20 ms actual sleep for any
- value given in the 1~20ms range). In many cases this
- is not the desired behavior.
-
- - Why is there no "usleep" / What is a good range?
- Since usleep_range is built on top of hrtimers, the
- wakeup will be very precise (ish), thus a simple
- usleep function would likely introduce a large number
- of undesired interrupts.
-
- With the introduction of a range, the scheduler is
- free to coalesce your wakeup with any other wakeup
- that may have happened for other reasons, or at the
- worst case, fire an interrupt for your upper bound.
-
- The larger a range you supply, the greater a chance
- that you will not trigger an interrupt; this should
- be balanced with what is an acceptable upper bound on
- delay / performance for your specific code path. Exact
- tolerances here are very situation specific, thus it
- is left to the caller to determine a reasonable range.
-
- SLEEPING FOR LARGER MSECS ( 10ms+ )
- * Use msleep or possibly msleep_interruptible
-
- - What's the difference?
- msleep sets the current task to TASK_UNINTERRUPTIBLE
- whereas msleep_interruptible sets the current task to
- TASK_INTERRUPTIBLE before scheduling the sleep. In
- short, the difference is whether the sleep can be ended
- early by a signal. In general, just use msleep unless
- you know you have a need for the interruptible variant.
-
- FLEXIBLE SLEEPING (any delay, uninterruptible)
- * Use fsleep

Un **algoritmo** contiene codice generico che può essere utilizzato per
implementare una intera classe di adattatori I2C. Ciascun driver dell'
adattatore specifico dipende da un driver dell'algoritmo nella sottocartella
``drivers/i2c/algos/`` o include la propria implementazione.

+Un circuito integrato **dispositivo** è un nodo che risponde alle comunicazioni
+quando indirizzato dal controllore. In Linux è chiamato **client**. Nonostante i
+dispositivi siano circuiti integrati esterni al sistema, Linux può agire come
+dispositivo (se l'hardware lo permette) e rispondere alla richieste di altri
+controllori sul bus. Questo verrà chiamato **dispositivo locale** (*local
+target*). Negli altri casi si parla di **dispositivo remoto** (*remote target*).
+
+I driver dei dispositivi sono contenuti in una cartella specifica per la
funzionalità che forniscono, ad esempio ``drivers/media/gpio/`` per espansori
GPIO e ``drivers/media/i2c/`` per circuiti integrati relativi ai video.
Per la configurazione di esempio in figura, avrai bisogno di un driver per il
tuo adattatore I2C e driver per i tuoi dispositivi I2C (solitamente un driver
per ciascuno dispositivo).
+
+Sinonimi
+--------
+
+Come menzionato precedentemente, per ragioni storiche l'implementazione I2C del
+kernel Linux usa "adatattore" (*adapter*) per i controllori e "client" per i
+dispositivi. Un certo numero di strutture dati usano questi sinonimi nei loro
+nomi. Dunque, durante le discussioni riguardanti l'implementazione dovrete
+essere a coscienza anche di questi termini. Tuttavia si preferiscono i termini
+ufficiali.
+
+Terminologia obsoleta
+---------------------
+
+Nelle prime specifiche di I2C, il controllore veniva chiamato "master" ed i
+dispositivi "slave". Questi termini sono stati resi obsoleti con la versione 7
+della specifica. Inoltre, il loro uso viene scoraggiato dal codice di condotta
+del kernel Linux. Tuttavia, potreste ancora trovare questi termini in pagine non
+aggiornate. In generale si cerca di usare i termini controllore e dispositivo.

+HacKerMaiL (TUI)
+****************
-Il servizio Proton Mail ha una funzionalità che cripta tutti i messaggi verso
-ogni destinatario per cui è possibile trovare una chiave usando il *Web Key
-Directory* (WKD). Il servizio kernel.org pubblica il WKD per ogni sviluppatore
-in possesso di un conto kernel.org. Di conseguenza, tutti i messaggi inviati
-usando Proton Mail verso indirizzi kernel.org verranno criptati.
-
-Proton Mail non fornisce alcun meccanismo per disabilitare questa funzionalità
-perché verrebbe considerato un problema per la riservatezza. Questa funzionalità
-è attiva anche quando si inviano messaggi usando il Proton Mail Bridge. Dunque
-tutta la posta in uscita verrà criptata, incluse le patch inviate con ``git
-send-email``.
-
-I messaggi criptati sono una fonte di problemi; altri sviluppatori potrebbero
-non aver configurato i loro programmi, o strumenti, per gestire messaggi
-criptati; inoltre, alcuni programmi di posta elettronica potrebbero criptare le
-risposte a messaggi criptati per tutti i partecipanti alla discussione, inclusa
-la lista di discussione stessa.
-
-A meno che non venga introdotta una maniera per disabilitare questa
-funzionalità, non è consigliato usare Proton Mail per contribuire allo sviluppo
-del kernel.
+HacKerMaiL (hkml) è una semplice casella pubblica per la gestione dei messaggi
+di posta che non richiede alcuna sottoscrizione ad una lista di discussione.
+Viene sviluppato e mantenuto dal manutentore di DAMON e si pone come obiettivo

+
1) Se state usando delle funzionalità del kernel allora includete (#include)
i file che le dichiarano/definiscono. Non dipendente dal fatto che un file
d'intestazione include anche quelli usati da voi.
-2) Compilazione pulita:
-
- a) con le opzioni ``CONFIG`` negli stati ``=y``, ``=m`` e ``=n``. Nessun
- avviso/errore di ``gcc`` e nessun avviso/errore dal linker.
-
- b) con ``allnoconfig``, ``allmodconfig``
-
- c) quando si usa ``O=builddir``
-
- d) Qualsiasi modifica in Documentation/ deve compilare con successo senza
- avvisi o errori. Usare ``make htmldocs`` o ``make pdfdocs`` per verificare
- e correggere i problemi
-
-3) Compilare per diverse architetture di processore usando strumenti per
- la cross-compilazione o altri.
+2) Controllate lo stile del codice della vostra patch secondo le direttive
+ scritte in :ref:`Documentation/translations/it_IT/process/coding-style.rst <it_codingstyle>`.
-4) Una buona architettura per la verifica della cross-compilazione è la ppc64
- perché tende ad usare ``unsigned long`` per le quantità a 64-bit.
+3) Tutte le barriere di sincronizzazione {per esempio, ``barrier()``,
+ ``rmb()``, ``wmb()``} devono essere accompagnate da un commento nei
+ sorgenti che ne spieghi la logica: cosa fanno e perché.
-5) Controllate lo stile del codice della vostra patch secondo le direttive
- scritte in :ref:`Documentation/translations/it_IT/process/coding-style.rst <it_codingstyle>`.
- Prima dell'invio della patch, usate il verificatore di stile
- (``script/checkpatch.pl``) per scovare le violazioni più semplici.
- Dovreste essere in grado di giustificare tutte le violazioni rimanenti nella
- vostra patch.

- ``CONFIG_DEBUG_SLAB``, ``CONFIG_DEBUG_PAGEALLOC``, ``CONFIG_DEBUG_MUTEXES``,
- ``CONFIG_DEBUG_SPINLOCK``, ``CONFIG_DEBUG_ATOMIC_SLEEP``,
- ``CONFIG_PROVE_RCU`` e ``CONFIG_DEBUG_OBJECTS_RCU_HEAD``.
+5) Tutte le nuove interfacce verso lo spazio utente sono documentate in
+ ``Documentation/ABI/``. Leggete ``Documentation/ABI/README`` per maggiori
+ informazioni. Le patch che modificano le interfacce utente dovrebbero
+ essere inviate in copia anche a linux-api@vger.kernel.org.

+en porciones de tiempo de ejecución en la CPU según los hilos de ejecución
+del grupo de tareas van siendo candidatos a ejecutarse. Una vez toda la cuota
+ha sido asignada cualquier petición adicional de cuota resultará en esos hilos
+de ejecución siendo limitados/estrangulados. Los hilos de ejecución limitados
+no serán capaces de ejecutarse de nuevo hasta el siguiente periodo cuando
+la cuota sea restablecida.
+
+La cuota sin asignar de un grupo es monitorizada globalmente, siendo
+restablecidas cfs_quota unidades al final de cada periodo. Según los
+hilos de ejecución van consumiendo este ancho de banda, este se
+transfiere a los "silos" de las cpu-locales en base a la demanda. La
+cantidad transferida en cada una de esas actualizaciones es ajustable y
+es descrito como un "slice".
+
+Característica de ráfaga
+--------------------------
+
+Esta característica toma prestado tiempo ahora, que en un futuro tendrá que
+devolver, con el coste de una mayor interferencia hacia los otros usuarios
+del sistema. Todo acotado perfectamente.
+
+El tradicional control de ancho de banda (UP-EDF) es algo como:
+
+ (U = \Sum u_i) <= 1
+
+Esto garantiza dos cosas: que cada tiempo límite de ejecución es cumplido
+y que el sistema es estable. De todas formas, si U fuese > 1, entonces
+por cada segundo de tiempo de reloj de una tarea, tendríamos que
+ejecutar más de un segundo y obviamente no se cumpliría con el tiempo
+límite de ejecución de la tarea, pero en el siguiente periodo de ejecución
+el tiempo límite de la tarea estaría todavía más lejos, y nunca se tendría
+tiempo de alcanzar la ejecución, cayendo así en un fallo no acotado.
+
+La característica de ráfaga implica que el trabajo de una tarea no siempre
+consuma totalmente la cuota; esto permite que se pueda describir u_i
+como una distribución estadística.
+
+Por ejemplo, se tiene u_i = {x,e}_i, donde x es el p(95) y x+e p(100)
+(el tradicional WCET (WCET:Worst Case Execution Time: son las siglas
+en inglés para "peor tiempo de ejecución")). Esto efectivamente permite
+a u ser más pequeño, aumentando la eficiencia (podemos ejecutar más
+tareas en el sistema), pero al coste de perder el instante límite de
+finalización deseado de la tarea, cuando coincidan las peores
+probabilidades. De todas formas, si se mantiene la estabilidad, ya que
+cada sobre-ejecución se empareja con una infra-ejecución en tanto x esté
+por encima de la media.
+
+Es decir, supóngase que se tienen 2 tareas, ambas específicamente
+con p(95), entonces tenemos p(95)*p(95) = 90.25% de probabilidad de
+que ambas tareas se ejecuten dentro de su cuota asignada y todo
+salga bien. Al mismo tiempo se tiene que p(5)*p(5) = 0.25% de
+probabilidad que ambas tareas excedan su cuota de ejecución (fallo
+garantizado de su tiempo final de ejecución). En algún punto por
+en medio, hay un umbral donde una tarea excede su tiempo límite de
+ejecución y la otra no, de forma que se compensan; esto depende de la
+función de probabilidad acumulada específica de la tarea.
+
+Al mismo tiempo, se puede decir que el peor caso de sobrepasar el
+tiempo límite de ejecución será \Sum e_i; esto es una retraso acotado
+(asumiendo que x+e es de hecho el WCET).
+
+La interferencia cuando se usa una ráfaga se evalúa por las posibilidades
+de fallar en el cumplimiento del tiempo límite y el promedio de WCET.
+Los resultados de los tests han mostrado que cuando hay muchos cgroups o
+una CPU está infrautilizada, la interferencia es más limitada. Más detalles
+se aportan en: https://lore.kernel.org/lkml/5371BD36-55AE-4F71-B9D7-B86DC32E3D2B@linux.alibaba.com/
+
+Gestión:
+--------
+
+Cuota, periodo y ráfaga se gestionan dentro del subsistema de cpu por medio
+de cgroupfs.
+
+.. note::
+ Los archivos cgroupfs descritos en esta sección solo se aplican al cgroup
+ v1. Para cgroup v2, ver :ref:`Documentation/admin-guide/cgroup-v2.rst <cgroup-v2-cpu>`.
+
+- cpu.cfs_quota_us: tiempo de ejecución que se refresca cada periodo (en microsegundos)
+- cpu.cfs_period_us: la duración del periodo (en microsegundos)
+- cpu.stat: exporta las estadísticas de limitación [explicado a continuación]
+- cpu.cfs_burst_us: el máximo tiempo de ejecución acumulado (en microsegundos)
+
+Los valores por defecto son::
+
+ cpu.cfs_period_us=100ms
+ cpu.cfs_quota_us=-1
+ cpu.cfs_burst_us=0
+
+Un valor de -1 para cpu.cfs_quota_us indica que el grupo no tiene ninguna
+restricción de ancho de banda aplicado, ese grupo se describe como un grupo
+con ancho de banda sin restringir. Esto representa el comportamiento
+tradicional para CFS.
+
+Asignar cualquier valor (válido) y positivo no menor que cpu.cfs_burst_us
+definirá el límite del ancho de banda. La cuota mínima permitida para
+la cuota o periodo es 1ms. Hay también un límite superior en la duración del
+periodo de 1s. Existen restricciones adicionales cuando los límites de
+ancho de banda se usan de manera jerárquica, estos se explican en mayor
+detalle más adelante.
+
+Asignar cualquier valor negativo a cpu.cfs_quota_us eliminará el límite de
+ancho de banda y devolverá de nuevo al grupo a un estado sin restricciones.
+
+Un valor de 0 para cpu.cfs_burst_us indica que el grupo no puede acumular
+ningún ancho de banda sin usar. Esto hace que el control del comportamiento
+tradicional del ancho de banda para CFS no cambie. Definir cualquier valor
+(válido) positivo no mayor que cpu.cfs_quota_us en cpu.cgs_burst_us definirá
+el límite con el ancho de banda acumulado no usado.
+
+Cualquier actualización a las especificaciones del ancho de banda usado
+por un grupo resultará en que se deje de limitar si está en un estado
+restringido.
+
+Ajustes globales del sistema
+----------------------------
+
+Por eficiencia el tiempo de ejecución es transferido en lotes desde una reserva
+global y el "silo" de una CPU local. Esto reduce en gran medida la presión
+por la contabilidad en grandes sistemas. La cantidad transferida cada vez
+que se requiere una actualización se describe como "slice".
+
+Esto es ajustable vía procfs::
+
+ /proc/sys/kernel/sched_cfs_bandwidth_slice_us (valor por defecto=5ms)
+
+Valores de "slice" más grandes reducirán el costo de transferencia, mientras
+que valores más pequeños permitirán un control más fino del consumo.
+
+Estadísticas
+------------
+
+Las estadísticas del ancho de banda de un grupo se exponen en 5 campos en cpu.stat.
+
+cpu.stat:
+
+- nr_periods: Número de intervalos aplicados que han pasado.
+- nr_throttled: Número de veces que el grupo ha sido restringido/limitado.
+- throttled_time: La duración de tiempo total (en nanosegundos) en las
+ que las entidades del grupo han sido limitadas.
+- nr_bursts: Número de periodos en que ha ocurrido una ráfaga.
+- burst_time: Tiempo acumulado (en nanosegundos) en la que una CPU ha
+ usado más de su cuota en los respectivos periodos.
+
+Este interfaz es de solo lectura.
+
+Consideraciones jerárquicas
+---------------------------
+
+La interfaz refuerza que el ancho de banda de una entidad individual
+sea siempre factible, esto es: max(c_i) <= C. De todas maneras,
+la sobre-suscripción en el caso agregado está explícitamente permitida
+para hacer posible semánticas de conservación de trabajo dentro de una
+jerarquia.
+
+ e.g. \Sum (c_i) puede superar C
+
+[ Donde C es el ancho de banda de el padre, y c_i el de su hijo ]
+
+Hay dos formas en las que un grupo puede ser limitado:
+
+ a. este consume totalmente su propia cuota en un periodo.
+ b. la cuota del padre es consumida totalmente en su periodo.
+
+En el caso b) anterior, incluso si el hijo pudiera tener tiempo de
+ejecución restante, este no le será permitido hasta que el tiempo de
+ejecución del padre sea actualizado.
+
+Advertencias sobre el CFS con control de cuota de ancho de banda
+----------------------------------------------------------------
+
+Una vez una "slice" se asigna a una cpu esta no expira. A pesar de eso todas,
+excepto las "slices" menos las de 1ms, puede ser devueltas a la reserva global
+si todos los hilos en esa cpu pasan a ser no ejecutables. Esto se configura
+en el tiempo de compilación por la variable min_cfs_rq_runtime. Esto es un
+ajuste en la eficacia que ayuda a prevenir añadir bloqueos en el candado global.
+
+El hecho de que las "slices" de una cpu local no expiren tiene como resultado
+algunos casos extremos interesantes que debieran ser comprendidos.
+
+Para una aplicación que es un cgroup y que está limitada en su uso de cpu
+es un punto discutible ya que de forma natural consumirá toda su parte
+de cuota así como también la totalidad de su cuota en cpu locales en cada
+periodo. Como resultado se espera que nr_periods sea aproximadamente igual
+a nr_throttled, y que cpuacct.usage se incremente aproximadamente igual
+a cfs_quota_us en cada periodo.
+
+Para aplicaciones que tienen un gran número de hilos de ejecución y que no
+estan ligadas a una cpu, este matiz de la no-expiración permite que las
+aplicaciones brevemente sobrepasen su cuota límite en la cantidad que
+no ha sido usada en cada cpu en la que el grupo de tareas se está ejecutando
+(típicamente como mucho 1ms por cada cpu o lo que se ha definido como
+min_cfs_rq_runtime). Este pequeño sobreuso únicamente tiene lugar si
+la cuota que ha sido asignada a una cpu y no ha sido completamente usada
+o devuelta en periodos anteriores. Esta cantidad de sobreuso no será
+transferida entre núcleos. Como resultado, este mecanismo todavía cumplirá
+estrictamente los límites de la tarea de grupo en el promedio del uso,
+pero sobre una ventana de tiempo mayor que un único periodo. Esto
+también limita la habilidad de un sobreuso a no más de 1ms por cada cpu.
+Esto provee de una experiencia de uso más predecible para aplicaciones
+con muchos hilos y con límites de cuota pequeños en máquinas con muchos
+núcleos. Esto también elimina la propensión a limitar estas
+aplicaciones mientras que simultáneamente usan menores cuotas
+de uso por cpu. Otra forma de decir esto es que permitiendo que
+la parte no usada de una "slice" permanezca válida entre periodos
+disminuye la posibilidad de malgastare cuota que va a expirar en
+las reservas de la cpu locales que no necesitan una "slice" completa
+de tiempo de ejecución de cpu.
+
+La interacción entre las aplicaciones ligadas a una CPU y las que no están
+ligadas a ninguna cpu ha de ser también considerada, especialmente cuando
+un único núcleo tiene un uso del 100%. Si se da a cada una de esas
+aplicaciones la mitad de la capacidad de una CPU-núcleo y ambas
+están gestionadas en la misma CPU es teóricamente posible que la aplicación
+no ligada a ninguna CPU use su 1ms adicional de cuota en algunos periodos,
+y por tanto evite que la aplicación ligada a una CPU pueda usar su
+cuota completa por esa misma cantidad. En esos caso el algoritmo CFS (vea
+sched-design-CFS.rst) el que decida qué aplicación es la elegida para
+ejecutarse, ya que ambas serán candidatas a ser ejecutadas y tienen
+cuota restante. Esta discrepancia en el tiempo de ejecución se compensará
+en los periodos siguientes cuando el sistema esté inactivo.
+
+Ejemplos
+---------
+
+1. Un grupo limitado a 1 CPU de tiempo de ejecución.
+
+ Si el periodo son 250ms y la cuota son 250ms el grupo de tareas tendrá el tiempo
+ de ejecución de 1 CPU cada 250ms::
+
+ # echo 250000 > cpu.cfs_quota_us /* cuota = 250ms */
+ # echo 250000 > cpu.cfs_period_us /* periodo = 250ms */
+
+2. Un grupo limitado al tiempo de ejecución de 2 CPUs en una máquina varias CPUs.
+
+ Con un periodo de 500ms y una cuota de 1000ms el grupo de tareas tiene el tiempo
+ de ejecución de 2 CPUs cada 500ms::
+
+ # echo 1000000 > cpu.cfs_quota_us /* cuota = 1000ms */
+ # echo 500000 > cpu.cfs_period_us /* periodo = 500ms */
+
+ El periodo más largo aquí permite una capacidad de ráfaga mayor.
+
+3. Un grupo limitado a un 20% de 1 CPU.
+
+ Con un periodo de 50ms, 10ms de cuota son equivalentes al 20% de 1 CPUs::
+
+ # echo 10000 > cpu.cfs_quota_us /* cuota = 10ms */
+ # echo 50000 > cpu.cfs_period_us /* periodo = 50ms */
+
+ Usando un periodo pequeño aquí nos aseguramos una respuesta de
+ la latencia consistente a expensas de capacidad de ráfaga.
+
+4. Un grupo limitado al 40% de 1 CPU, y permite acumular adicionalmente
+ hasta un 20% de 1 CPU.
+
+ Con un periodo de 50ms, 20ms de cuota son equivalentes al 40% de
+ 1 CPU. Y 10ms de ráfaga, son equivalentes a un 20% de 1 CPU::
+
+ # echo 20000 > cpu.cfs_quota_us /* cuota = 20ms */
+ # echo 50000 > cpu.cfs_period_us /* periodo = 50ms */
+ # echo 10000 > cpu.cfs_burst_us /* ráfaga = 10ms */
+
+ Un ajuste mayor en la capacidad de almacenamiento (no mayor que la cuota)
+ permite una mayor capacidad de ráfaga.

+
+本文档介ç»å¦‚何使用 Clang å’Œ LLVM 工具构建 Linux 内核。
+
+关于
+----
+
+Linux 内核传统上一直使用 GNU 工具链(如 GCC å’Œ binutils)进行编译。æŒç»­çš„工作使得
+`Clang <https://clang.llvm.org/>`_ å’Œ `LLVM <https://llvm.org/>`_ 工具å¯
+作为å¯è¡Œçš„æ›¿ä»£å“。一些å‘行版,如 `Android <https://www.android.com/>`_ã€
+`ChromeOS <https://www.chromium.org/chromium-os>`_ã€`OpenMandriva
+<https://www.openmandriva.org/>`_ 和 `Chimera Linux
+<https://chimera-linux.org/>`_ 使用 Clang 编译的内核。谷歌和 Meta 的数æ®ä¸­å¿ƒ
+集群也è¿è¡Œç”± Clang 编译的内核。
+
+`LLVM 是由 C++ å¯¹è±¡å®žçŽ°çš„å·¥å…·é“¾ç»„ä»¶é›†åˆ <https://www.aosabook.org/en/llvm.html>`_。
+Clang 是 LLVM çš„å‰ç«¯ï¼Œæ”¯æŒ C 语言和内核所需的 GNU C 扩展,其å‘音为 "klang",而éž
+"see-lang"。
+
+使用 LLVM 构建
+--------------
+
+通过以下命令调用 ``make``::
+
+ make LLVM=1
+
+为主机目标进行编译。对于交å‰ç¼–译::
+
+ make LLVM=1 ARCH=arm64
+
+LLVM= 傿•°
+----------
+
+LLVM 有 GNU binutils 工具的替代å“。这些工具å¯ä»¥å•独å¯ç”¨ã€‚以下是支æŒçš„ make å˜é‡
+完整列表::
+
+ make CC=clang LD=ld.lld AR=llvm-ar NM=llvm-nm STRIP=llvm-strip \
+ OBJCOPY=llvm-objcopy OBJDUMP=llvm-objdump READELF=llvm-readelf \
+ HOSTCC=clang HOSTCXX=clang++ HOSTAR=llvm-ar HOSTLD=ld.lld
+
+``LLVM=1`` 扩展为上述命令。
+
+如果你的 LLVM 工具ä¸åœ¨ PATH 中,你å¯ä»¥ä½¿ç”¨ä»¥æ–œæ ç»“尾的 LLVM å˜é‡æä¾›å®ƒä»¬çš„ä½ç½®::
+
+ make LLVM=/path/to/llvm/
+
+这将使用 ``/path/to/llvm/clang``ã€``/path/to/llvm/ld.lld`` 等工具。也å¯ä»¥
+使用以下命令::
+
+ PATH=/path/to/llvm:$PATH make LLVM=1
+
+如果你的 LLVM 工具带有版本åŽç¼€ï¼Œå¹¶ä¸”ä½ å¸Œæœ›æµ‹è¯•è¯¥ç‰¹å®šç‰ˆæœ¬è€Œéžæ— åŽç¼€çš„坿‰§è¡Œæ–‡ä»¶ï¼Œ
+类似于 ``LLVM=1``,你å¯ä»¥ä½¿ç”¨ ``LLVM`` å˜é‡ä¼ é€’该åŽç¼€::
+
+ make LLVM=-14
+
+这将使用 ``clang-14``ã€``ld.lld-14`` 等工具。为了支æŒå¸¦æœ‰ç‰ˆæœ¬åŽç¼€çš„æ ‘外路径组åˆï¼Œ
+我们建议::
+
+ PATH=/path/to/llvm/:$PATH make LLVM=-14
+
+``LLVM=0`` 与çœç•¥ ``LLVM`` 完全ä¸åŒï¼Œå®ƒå°†è¡¨çŽ°å¾—åƒ ``LLVM=1``。如果你åªå¸Œæœ›ä½¿ç”¨

------------
-The mseal() syscall has the following signature:
-
-``int mseal(void addr, size_t len, unsigned long flags)``
-
-**addr/len**: virtual memory address range.
-
-The address range set by ``addr``/``len`` must meet:
- - The start address must be in an allocated VMA.
- - The start address must be page aligned.
- - The end address (``addr`` + ``len``) must be in an allocated VMA.
- - no gap (unallocated memory) between start and end address.
-
-The ``len`` will be paged aligned implicitly by the kernel.
-
-**flags**: reserved for future use.
-
-**return values**:
-
-- ``0``: Success.
-
-- ``-EINVAL``:
- - Invalid input ``flags``.
- - The start address (``addr``) is not page aligned.
- - Address range (``addr`` + ``len``) overflow.
-
-- ``-ENOMEM``:
- - The start address (``addr``) is not allocated.
- - The end address (``addr`` + ``len``) is not allocated.
- - A gap (unallocated memory) between start and end address.
-
-- ``-EPERM``:
- - sealing is supported only on 64-bit CPUs, 32-bit is not supported.
-
-- For above error cases, users can expect the given memory range is
- unmodified, i.e. no partial update.
-
-- There might be other internal errors/cases not listed here, e.g.
- error during merging/splitting VMAs, or the process reaching the max
- number of supported VMAs. In those cases, partial updates to the given
- memory range could happen. However, those cases should be rare.
-
-**Blocked operations after sealing**:
- Unmapping, moving to another location, and shrinking the size,
- via munmap() and mremap(), can leave an empty space, therefore
- can be replaced with a VMA with a new set of attributes.
-
- Moving or expanding a different VMA into the current location,
- via mremap().
-
- Modifying a VMA via mmap(MAP_FIXED).
-
- Size expansion, via mremap(), does not appear to pose any
- specific risks to sealed VMAs. It is included anyway because
- the use case is unclear. In any case, users can rely on
- merging to expand a sealed VMA.
-
- mprotect() and pkey_mprotect().
-
- Some destructive madvice() behaviors (e.g. MADV_DONTNEED)
- for anonymous memory, when users don't have write permission to the
- memory. Those behaviors can alter region contents by discarding pages,
- effectively a memset(0) for anonymous memory.
-
- Kernel will return -EPERM for blocked operations.
-
- For blocked operations, one can expect the given address is unmodified,
- i.e. no partial update. Note, this is different from existing mm
- system call behaviors, where partial updates are made till an error is
- found and returned to userspace. To give an example:
-
- Assume following code sequence:
-
- - ptr = mmap(null, 8192, PROT_NONE);
- - munmap(ptr + 4096, 4096);
- - ret1 = mprotect(ptr, 8192, PROT_READ);
- - mseal(ptr, 4096);
- - ret2 = mprotect(ptr, 8192, PROT_NONE);
-
- ret1 will be -ENOMEM, the page from ptr is updated to PROT_READ.
-
- ret2 will be -EPERM, the page remains to be PROT_READ.
-
-**Note**:
-
-- mseal() only works on 64-bit CPUs, not 32-bit CPU.
-
-- users can call mseal() multiple times, mseal() on an already sealed memory

+SYSCALL
+=======
+mseal syscall signature
+-----------------------
+ ``int mseal(void \* addr, size_t len, unsigned long flags)``
+
+ **addr**/**len**: virtual memory address range.
+ The address range set by **addr**/**len** must meet:
+ - The start address must be in an allocated VMA.
+ - The start address must be page aligned.
+ - The end address (**addr** + **len**) must be in an allocated VMA.
+ - no gap (unallocated memory) between start and end address.
+
+ The ``len`` will be paged aligned implicitly by the kernel.
+
+ **flags**: reserved for future use.
+
+ **Return values**:
+ - **0**: Success.
+ - **-EINVAL**:
+ * Invalid input ``flags``.
+ * The start address (``addr``) is not page aligned.
+ * Address range (``addr`` + ``len``) overflow.
+ - **-ENOMEM**:
+ * The start address (``addr``) is not allocated.

+ * A gap (unallocated memory) between start and end address.
+ - **-EPERM**:
+ * sealing is supported only on 64-bit CPUs, 32-bit is not supported.
+
+ **Note about error return**:
+ - For above error cases, users can expect the given memory range is
+ unmodified, i.e. no partial update.
+ - There might be other internal errors/cases not listed here, e.g.
+ error during merging/splitting VMAs, or the process reaching the maximum
+ number of supported VMAs. In those cases, partial updates to the given
+ memory range could happen. However, those cases should be rare.
+
+ **Architecture support**:
+ mseal only works on 64-bit CPUs, not 32-bit CPUs.
+
+ **Idempotent**:
+ users can call mseal multiple times. mseal on an already sealed memory
+ is a no-action (not error).
+
+ **no munseal**
+ Once mapping is sealed, it can't be unsealed. The kernel should never
+ have munseal, this is consistent with other sealing feature, e.g.
+ F_SEAL_SEAL for file.
+
+Blocked mm syscall for sealed mapping
+-------------------------------------
+ It might be important to note: **once the mapping is sealed, it will
+ stay in the process's memory until the process terminates**.
+
+ Example::
+
+ *ptr = mmap(0, 4096, PROT_READ, MAP_ANONYMOUS | MAP_PRIVATE, 0, 0);
+ rc = mseal(ptr, 4096, 0);
+ /* munmap will fail */
+ rc = munmap(ptr, 4096);
+ assert(rc < 0);
+
+ Blocked mm syscall:
+ - munmap
+ - mmap
+ - mremap
+ - mprotect and pkey_mprotect
+ - some destructive madvise behaviors: MADV_DONTNEED, MADV_FREE,
+ MADV_DONTNEED_LOCKED, MADV_FREE, MADV_DONTFORK, MADV_WIPEONFORK
+
+ The first set of syscalls to block is munmap, mremap, mmap. They can
+ either leave an empty space in the address space, therefore allowing
+ replacement with a new mapping with new set of attributes, or can
+ overwrite the existing mapping with another mapping.
+
+ mprotect and pkey_mprotect are blocked because they changes the
+ protection bits (RWX) of the mapping.
+
+ Certain destructive madvise behaviors, specifically MADV_DONTNEED,
+ MADV_FREE, MADV_DONTNEED_LOCKED, and MADV_WIPEONFORK, can introduce
+ risks when applied to anonymous memory by threads lacking write
+ permissions. Consequently, these operations are prohibited under such
+ conditions. The aforementioned behaviors have the potential to modify
+ region contents by discarding pages, effectively performing a memset(0)
+ operation on the anonymous memory.
+
+ Kernel will return -EPERM for blocked syscalls.
+
+ When blocked syscall return -EPERM due to sealing, the memory regions may
+ or may not be changed, depends on the syscall being blocked:
+
+ - munmap: munmap is atomic. If one of VMAs in the given range is
+ sealed, none of VMAs are updated.
+ - mprotect, pkey_mprotect, madvise: partial update might happen, e.g.
+ when mprotect over multiple VMAs, mprotect might update the beginning
+ VMAs before reaching the sealed VMA and return -EPERM.
+ - mmap and mremap: undefined behavior.

+ mapping segments.
-Notes on which memory to seal:
-==============================
+- Chrome browser: protect some security sensitive data structures.
-It might be important to note that sealing changes the lifetime of a mapping,
-i.e. the sealed mapping won’t be unmapped till the process terminates or the
-exec system call is invoked. Applications can apply sealing to any virtual
-memory region from userspace, but it is crucial to thoroughly analyze the
-mapping's lifetime prior to apply the sealing.
+When not to use mseal
+=====================
+Applications can apply sealing to any virtual memory region from userspace,
+but it is *crucial to thoroughly analyze the mapping's lifetime* prior to
+apply the sealing. This is because the sealed mapping *won’t be unmapped*
+until the process terminates or the exec system call is invoked.
For example:
+ - aio/shm
+ aio/shm can call mmap and munmap on behalf of userspace, e.g.
+ ksys_shmdt() in shm.c. The lifetimes of those mapping are not tied to
+ the lifetime of the process. If those memories are sealed from userspace,
+ then munmap will fail, causing leaks in VMA address space during the
+ lifetime of the process.
+
+ - ptr allocated by malloc (heap)
+ Don't use mseal on the memory ptr return from malloc().
+ malloc() is implemented by allocator, e.g. by glibc. Heap manager might
+ allocate a ptr from brk or mapping created by mmap.
+ If an app calls mseal on a ptr returned from malloc(), this can affect
+ the heap manager's ability to manage the mappings; the outcome is
+ non-deterministic.
+
+ Example::
+
+ ptr = malloc(size);
+ /* don't call mseal on ptr return from malloc. */
+ mseal(ptr, size);
+ /* free will success, allocator can't shrink heap lower than ptr */
+ free(ptr);
+
+mseal doesn't block
+===================
+In a nutshell, mseal blocks certain mm syscall from modifying some of VMA's
+attributes, such as protection bits (RWX). Sealed mappings doesn't mean the
+memory is immutable.
-- aio/shm
-
- aio/shm can call mmap()/munmap() on behalf of userspace, e.g. ksys_shmdt() in
- shm.c. The lifetime of those mapping are not tied to the lifetime of the
- process. If those memories are sealed from userspace, then munmap() will fail,
- causing leaks in VMA address space during the lifetime of the process.
-
-- Brk (heap)
-
- Currently, userspace applications can seal parts of the heap by calling
- malloc() and mseal().
- let's assume following calls from user space:
-
- - ptr = malloc(size);
- - mprotect(ptr, size, RO);
- - mseal(ptr, size);
- - free(ptr);
-
- Technically, before mseal() is added, the user can change the protection of
- the heap by calling mprotect(RO). As long as the user changes the protection
- back to RW before free(), the memory range can be reused.
-
- Adding mseal() into the picture, however, the heap is then sealed partially,
- the user can still free it, but the memory remains to be RO. If the address
- is re-used by the heap manager for another malloc, the process might crash
- soon after. Therefore, it is important not to apply sealing to any memory
- that might get recycled.
-
- Furthermore, even if the application never calls the free() for the ptr,
- the heap manager may invoke the brk system call to shrink the size of the
- heap. In the kernel, the brk-shrink will call munmap(). Consequently,
- depending on the location of the ptr, the outcome of brk-shrink is
- nondeterministic.
-
-
-Additional notes:
-=================
As Jann Horn pointed out in [3], there are still a few ways to write
-to RO memory, which is, in a way, by design. Those cases are not covered
-by mseal(). If applications want to block such cases, sandbox tools (such as
-seccomp, LSM, etc) might be considered.

+ * Pairwise long polynomial multiplication of two 16-bit values
+ *
+ * { w0, w1 }, { y0, y1 }
+ *
+ * by two 64-bit values
+ *
+ * { x0, x1, x2, x3, x4, x5, x6, x7 }, { z0, z1, z2, z3, z4, z5, z6, z7 }
+ *
+ * where each vector element is a byte, ordered from least to most
+ * significant. The resulting 80-bit vectors are XOR'ed together.
+ *
+ * This can be implemented using 8x8 long polynomial multiplication, by
+ * reorganizing the input so that each pairwise 8x8 multiplication
+ * produces one of the terms from the decomposition below, and
+ * combining the results of each rank and shifting them into place.
+ *
+ * Rank
+ * 0 w0*x0 ^ | y0*z0 ^
+ * 1 (w0*x1 ^ w1*x0) << 8 ^ | (y0*z1 ^ y1*z0) << 8 ^
+ * 2 (w0*x2 ^ w1*x1) << 16 ^ | (y0*z2 ^ y1*z1) << 16 ^
+ * 3 (w0*x3 ^ w1*x2) << 24 ^ | (y0*z3 ^ y1*z2) << 24 ^
+ * 4 (w0*x4 ^ w1*x3) << 32 ^ | (y0*z4 ^ y1*z3) << 32 ^
+ * 5 (w0*x5 ^ w1*x4) << 40 ^ | (y0*z5 ^ y1*z4) << 40 ^
+ * 6 (w0*x6 ^ w1*x5) << 48 ^ | (y0*z6 ^ y1*z5) << 48 ^
+ * 7 (w0*x7 ^ w1*x6) << 56 ^ | (y0*z7 ^ y1*z6) << 56 ^
+ * 8 w1*x7 << 64 | y1*z7 << 64
+ *
+ * The inputs can be reorganized into
+ *
+ * { w0, w0, w0, w0, y0, y0, y0, y0 }, { w1, w1, w1, w1, y1, y1, y1, y1 }
+ * { x0, x2, x4, x6, z0, z2, z4, z6 }, { x1, x3, x5, x7, z1, z3, z5, z7 }
+ *
+ * and after performing 8x8->16 bit long polynomial multiplication of
+ * each of the halves of the first vector with those of the second one,
+ * we obtain the following four vectors of 16-bit elements:
+ *
+ * a := { w0*x0, w0*x2, w0*x4, w0*x6 }, { y0*z0, y0*z2, y0*z4, y0*z6 }
+ * b := { w0*x1, w0*x3, w0*x5, w0*x7 }, { y0*z1, y0*z3, y0*z5, y0*z7 }
+ * c := { w1*x0, w1*x2, w1*x4, w1*x6 }, { y1*z0, y1*z2, y1*z4, y1*z6 }
+ * d := { w1*x1, w1*x3, w1*x5, w1*x7 }, { y1*z1, y1*z3, y1*z5, y1*z7 }
+ *
+ * Results b and c can be XORed together, as the vector elements have
+ * matching ranks. Then, the final XOR can be pulled forward, and
+ * applied between the halves of each of the remaining three vectors,
+ * which are then shifted into place, and XORed together to produce the
+ * final 80-bit result.

+ * Pairwise long polynomial multiplication of two 16-bit values
+ *
+ * { w0, w1 }, { y0, y1 }
+ *
+ * by two 64-bit values
+ *
+ * { x0, x1, x2, x3, x4, x5, x6, x7 }, { z0, z1, z2, z3, z4, z5, z6, z7 }
+ *
+ * where each vector element is a byte, ordered from least to most
+ * significant.
+ *
+ * This can be implemented using 8x8 long polynomial multiplication, by
+ * reorganizing the input so that each pairwise 8x8 multiplication
+ * produces one of the terms from the decomposition below, and
+ * combining the results of each rank and shifting them into place.
+ *
+ * Rank
+ * 0 w0*x0 ^ | y0*z0 ^
+ * 1 (w0*x1 ^ w1*x0) << 8 ^ | (y0*z1 ^ y1*z0) << 8 ^
+ * 2 (w0*x2 ^ w1*x1) << 16 ^ | (y0*z2 ^ y1*z1) << 16 ^
+ * 3 (w0*x3 ^ w1*x2) << 24 ^ | (y0*z3 ^ y1*z2) << 24 ^
+ * 4 (w0*x4 ^ w1*x3) << 32 ^ | (y0*z4 ^ y1*z3) << 32 ^
+ * 5 (w0*x5 ^ w1*x4) << 40 ^ | (y0*z5 ^ y1*z4) << 40 ^
+ * 6 (w0*x6 ^ w1*x5) << 48 ^ | (y0*z6 ^ y1*z5) << 48 ^
+ * 7 (w0*x7 ^ w1*x6) << 56 ^ | (y0*z7 ^ y1*z6) << 56 ^
+ * 8 w1*x7 << 64 | y1*z7 << 64
+ *
+ * The inputs can be reorganized into
+ *
+ * { w0, w0, w0, w0, y0, y0, y0, y0 }, { w1, w1, w1, w1, y1, y1, y1, y1 }
+ * { x0, x2, x4, x6, z0, z2, z4, z6 }, { x1, x3, x5, x7, z1, z3, z5, z7 }
+ *
+ * and after performing 8x8->16 bit long polynomial multiplication of
+ * each of the halves of the first vector with those of the second one,
+ * we obtain the following four vectors of 16-bit elements:
+ *
+ * a := { w0*x0, w0*x2, w0*x4, w0*x6 }, { y0*z0, y0*z2, y0*z4, y0*z6 }
+ * b := { w0*x1, w0*x3, w0*x5, w0*x7 }, { y0*z1, y0*z3, y0*z5, y0*z7 }
+ * c := { w1*x0, w1*x2, w1*x4, w1*x6 }, { y1*z0, y1*z2, y1*z4, y1*z6 }
+ * d := { w1*x1, w1*x3, w1*x5, w1*x7 }, { y1*z1, y1*z3, y1*z5, y1*z7 }
+ *
+ * Results b and c can be XORed together, as the vector elements have
+ * matching ranks. Then, the final XOR (*) can be pulled forward, and
+ * applied between the halves of each of the remaining three vectors,
+ * which are then shifted into place, and combined to produce two
+ * 80-bit results.
+ *
+ * (*) NOTE: the 16x64 bit polynomial multiply below is not equivalent
+ * to the 64x64 bit one above, but XOR'ing the outputs together will
+ * produce the expected result, and this is sufficient in the context of
+ * this algorithm.

+ * Use CC_IPM(sym) at the end of the inline assembly; this extracts the

+ * the variable with symbolic name [sym] if the compiler has no support for
+ * flag output operands. If the compiler has support for flag output operands
+ * this generates no code.
+ *
+ * Use CC_OUT(sym, var) at the output operand list of an inline assembly. This
+ * defines an output operand with symbolic name [sym] for the variable
+ * [var]. [var] must be an int variable and [sym] must be identical with [sym]
+ * used with CC_IPM().
+ *
+ * Use either CC_CLOBBER or CC_CLOBBER_LIST() for the clobber list. Use
+ * CC_CLOBBER if the clobber list contains only "cc", otherwise use
+ * CC_CLOBBER_LIST() and add all clobbers as argument to the macro.
+ *
+ * Use CC_TRANSFORM() to convert the variable [var] which contains the
+ * extracted condition code. If the condition code is extracted with ipm, the
+ * [var] also contains the program mask. CC_TRANSFORM() moves the condition
+ * code to the two least significant bits and sets all other bits to zero.

- * ---------------------------
- * C states, especially those with large exit latencies, can have a real
- * noticeable impact on workloads, which is not acceptable for most sysadmins,
- * and in addition, less performance has a power price of its own.
- *
- * As a general rule of thumb, menu assumes that the following heuristic
- * holds:
- * The busier the system, the less impact of C states is acceptable
- *
- * This rule-of-thumb is implemented using a performance-multiplier:
- * If the exit latency times the performance multiplier is longer than
- * the predicted duration, the C state is not considered a candidate
- * for selection due to a too high performance impact. So the higher
- * this multiplier is, the longer we need to be idle to pick a deep C
- * state, and thus the less likely a busy CPU will hit such a deep
- * C state.
- *
- * Currently there is only one value determining the factor:
- * 10 points are added for each process that is waiting for IO on this CPU.
- * (This value was experimentally determined.)
- * Utilization is no longer a factor as it was shown that it never contributed
- * significantly to the performance multiplier in the first place.

+ *
+ * When inserting delays in non atomic context which are shorter than the time
+ * which is required to queue e.g. an hrtimer and to enter then the scheduler,
+ * it is also valuable to use udelay(). But it is not simple to specify a
+ * generic threshold for this which will fit for all systems. An approximation
+ * is a threshold for all delays up to 10 microseconds.
+ *
+ * When having a delay which is larger than the architecture specific
+ * %MAX_UDELAY_MS value, please make sure mdelay() is used. Otherwise a overflow
+ * risk is given.
+ *
+ * Please note that ndelay(), udelay() and mdelay() may return early for several
+ * reasons (https://lists.openwall.net/linux-kernel/2011/01/09/56):
+ *
+ * #. computed loops_per_jiffy too low (due to the time taken to execute the

+ *
+ * - Registers for passing the parameters to callee, including the stack
+ * pointer. (e.g. rcx, rdx, rdi, rsi, r8, r9 and rsp on x86_64)
+ * - Registers for passing the return values to caller.
+ * (e.g. rax and rdx on x86_64)
+ * - Registers for hooking the function call and return including the
+ * frame pointer (the frame pointer is architecture/config dependent)
+ * (e.g. rip, rbp and rsp for x86_64)
+ *
+ * Also, architecture dependent fields can be used for internal process.
+ * (e.g. orig_ax on x86_64)
+ *
+ * On the function entry, those registers will be restored except for
+ * the stack pointer, so that user can change the function parameters
+ * and instruction pointer (e.g. live patching.)
+ * On the function exit, only registers which is used for return values
+ * are restored.
+ *
+ * NOTE: user *must not* access regs directly, only do it via APIs, because
+ * the member can be changed according to the architecture.
+ * This is why the structure is empty here, so that nothing accesses
+ * the ftrace_regs directly.

+ * copy_struct_to_user: copy a struct to userspace
+ * @dst: Destination address, in userspace. This buffer must be @ksize
+ * bytes long.
+ * @usize: (Alleged) size of @dst struct.
+ * @src: Source address, in kernel space.
+ * @ksize: Size of @src struct.
+ * @ignored_trailing: Set to %true if there was a non-zero byte in @src that
+ * userspace cannot see because they are using an smaller struct.
+ *
+ * Copies a struct from kernel space to userspace, in a way that guarantees
+ * backwards-compatibility for struct syscall arguments (as long as future
+ * struct extensions are made such that all new fields are *appended* to the
+ * old struct, and zeroed-out new fields have the same meaning as the old
+ * struct).
+ *
+ * Some syscalls may wish to make sure that userspace knows about everything in
+ * the struct, and if there is a non-zero value that userspce doesn't know
+ * about, they want to return an error (such as -EMSGSIZE) or have some other
+ * fallback (such as adding a "you're missing some information" flag). If
+ * @ignored_trailing is non-%NULL, it will be set to %true if there was a
+ * non-zero byte that could not be copied to userspace (ie. was past @usize).
+ *
+ * While unconditionally returning an error in this case is the simplest
+ * solution, for maximum backward compatibility you should try to only return
+ * -EMSGSIZE if the user explicitly requested the data that couldn't be copied.
+ * Note that structure sizes can change due to header changes and simple
+ * recompilations without code changes(!), so if you care about
+ * @ignored_trailing you probably want to make sure that any new field data is
+ * associated with a flag. Otherwise you might assume that a program knows
+ * about data it does not.
+ *
+ * @ksize is just sizeof(*src), and @usize should've been passed by userspace.
+ * The recommended usage is something like the following:
+ *
+ * SYSCALL_DEFINE2(foobar, struct foo __user *, uarg, size_t, usize)
+ * {
+ * int err;
+ * bool ignored_trailing;
+ * struct foo karg = {};
+ *
+ * if (usize > PAGE_SIZE)
+ * return -E2BIG;
+ * if (usize < FOO_SIZE_VER0)
+ * return -EINVAL;
+ *
+ * // ... modify karg somehow ...
+ *
+ * err = copy_struct_to_user(uarg, usize, &karg, sizeof(karg),
+ * &ignored_trailing);
+ * if (err)
+ * return err;
+ * if (ignored_trailing)
+ * return -EMSGSIZE:
+ *
+ * // ...
+ * }
+ *
+ * There are three cases to consider:
+ * * If @usize == @ksize, then it's copied verbatim.
+ * * If @usize < @ksize, then the kernel is trying to pass userspace a newer
+ * struct than it supports. Thus we only copy the interoperable portions
+ * (@usize) and ignore the rest (but @ignored_trailing is set to %true if
+ * any of the trailing (@ksize - @usize) bytes are non-zero).
+ * * If @usize > @ksize, then the kernel is trying to pass userspace an older
+ * struct than userspace supports. In order to make sure the
+ * unknown-to-the-kernel fields don't contain garbage values, we zero the
+ * trailing (@usize - @ksize) bytes.
+ *

+/// Wraps the kernel's `struct file`. Thread safe.
+///
+/// This represents an open file rather than a file on a filesystem. Processes generally reference
+/// open files using file descriptors. However, file descriptors are not the same as files. A file
+/// descriptor is just an integer that corresponds to a file, and a single file may be referenced
+/// by multiple file descriptors.
+///
+/// # Refcounting
+///
+/// Instances of this type are reference-counted. The reference count is incremented by the
+/// `fget`/`get_file` functions and decremented by `fput`. The Rust type `ARef<File>` represents a
+/// pointer that owns a reference count on the file.
+///
+/// Whenever a process opens a file descriptor (fd), it stores a pointer to the file in its fd
+/// table (`struct files_struct`). This pointer owns a reference count to the file, ensuring the
+/// file isn't prematurely deleted while the file descriptor is open. In Rust terminology, the
+/// pointers in `struct files_struct` are `ARef<File>` pointers.
+///
+/// ## Light refcounts
+///
+/// Whenever a process has an fd to a file, it may use something called a "light refcount" as a
+/// performance optimization. Light refcounts are acquired by calling `fdget` and released with
+/// `fdput`. The idea behind light refcounts is that if the fd is not closed between the calls to
+/// `fdget` and `fdput`, then the refcount cannot hit zero during that time, as the `struct
+/// files_struct` holds a reference until the fd is closed. This means that it's safe to access the
+/// file even if `fdget` does not increment the refcount.
+///
+/// The requirement that the fd is not closed during a light refcount applies globally across all
+/// threads - not just on the thread using the light refcount. For this reason, light refcounts are
+/// only used when the `struct files_struct` is not shared with other threads, since this ensures
+/// that other unrelated threads cannot suddenly start using the fd and close it. Therefore,
+/// calling `fdget` on a shared `struct files_struct` creates a normal refcount instead of a light
+/// refcount.
+///
+/// Light reference counts must be released with `fdput` before the system call returns to
+/// userspace. This means that if you wait until the current system call returns to userspace, then
+/// all light refcounts that existed at the time have gone away.
+///
+/// ### The file position
+///
+/// Each `struct file` has a position integer, which is protected by the `f_pos_lock` mutex.
+/// However, if the `struct file` is not shared, then the kernel may avoid taking the lock as a
+/// performance optimization.
+///
+/// The condition for avoiding the `f_pos_lock` mutex is different from the condition for using
+/// `fdget`. With `fdget`, you may avoid incrementing the refcount as long as the current fd table
+/// is not shared; it is okay if there are other fd tables that also reference the same `struct
+/// file`. However, `fdget_pos` can only avoid taking the `f_pos_lock` if the entire `struct file`
+/// is not shared, as different processes with an fd to the same `struct file` share the same
+/// position.
+///
+/// To represent files that are not thread safe due to this optimization, the [`LocalFile`] type is
+/// used.
+///
+/// ## Rust references
+///
+/// The reference type `&File` is similar to light refcounts:
+///
+/// * `&File` references don't own a reference count. They can only exist as long as the reference
+/// count stays positive, and can only be created when there is some mechanism in place to ensure
+/// this.
+///
+/// * The Rust borrow-checker normally ensures this by enforcing that the `ARef<File>` from which
+/// a `&File` is created outlives the `&File`.
+///
+/// * Using the unsafe [`File::from_raw_file`] means that it is up to the caller to ensure that the
+/// `&File` only exists while the reference count is positive.
+///
+/// * You can think of `fdget` as using an fd to look up an `ARef<File>` in the `struct
+/// files_struct` and create an `&File` from it. The "fd cannot be closed" rule is like the Rust
+/// rule "the `ARef<File>` must outlive the `&File`".
+///
+/// # Invariants
+///
+/// * All instances of this type are refcounted using the `f_count` field.
+/// * There must not be any active calls to `fdget_pos` on this file that did not take the
+/// `f_pos_lock` mutex.

- Say Y here if you want to include TOMOYO without bloating
- vmlinux file. If you say Y, most of TOMOYO code is cut out to
- a loadable kernel module named tomoyo.ko . This option will be
- useful for kernels built by Linux distributors where TOMOYO is
- included but TOMOYO is not enabled by default. Please be sure
- to explicitly load tomoyo.ko if you want to activate TOMOYO
- without calling userspace policy loader, for tomoyo.ko is
- loaded immediately before calling userspace policy loader.

+ *
+ * Test describing a clear distinction between signal states - delivered and
+ * blocked, and their relation with ucontext.
+ *
+ * A process can request blocking of a signal by masking it into its set of
+ * blocked signals; such a signal, when sent to the process by the kernel,
+ * will get blocked by the process and it may later unblock it and take an
+ * action. At that point, the signal will be delivered.
+ *
+ * We test the following functionalities of the kernel:
+ *
+ * ucontext_t describes the interrupted context of the thread; this implies
+ * that, in case of registering a handler and catching the corresponding
+ * signal, that state is before what was jumping into the handler.
+ *
+ * The thread's mask of blocked signals can be permanently changed, i.e, not
+ * just during the execution of the handler, by mangling with uc_sigmask
+ * from inside the handler.
+ *
+ * Assume that we block the set of signals, S1, by sigaction(), and say, the
+ * signal for which the handler was installed, is S2. When S2 is sent to the
+ * program, it will be considered "delivered", since we will act on the
+ * signal and jump to the handler. Any instances of S1 or S2 raised, while the
+ * program is executing inside the handler, will be blocked; they will be
+ * delivered immediately upon termination of the handler.
+ *
+ * For standard signals (also see real-time signals in the man page), multiple
+ * blocked instances of the same signal are not queued; such a signal will
+ * be delivered just once.
