The sequences of operations for +exposing data range from simple to very complex. Because most of the +vulnerabilities require the attacker to have access to MMIO, many environments +are not affected. System environments using virtualization where MMIO access is +provided to untrusted guests may need mitigation. These vulnerabilities are +not transient execution attacks. However, these vulnerabilities may propagate +stale data into core fill buffers where the data can subsequently be inferred +by an unmitigated transient execution attack. Mitigation for these +vulnerabilities includes a combination of microcode update and software +changes, depending on the platform and usage model. Some of these mitigations +are similar to those used to mitigate Microarchitectural Data Sampling (MDS) or +those used to mitigate Special Register Buffer Data Sampling (SRBDS). + +Data Propagators +================ +Propagators are operations that result in stale data being copied or moved from +one microarchitectural buffer or register to another. Processor MMIO Stale Data +Vulnerabilities are operations that may result in stale data being directly +read into an architectural, software-visible state or sampled from a buffer or +register. + +Fill Buffer Stale Data Propagator (FBSDP) +----------------------------------------- +Stale data may propagate from fill buffers (FB) into the non-coherent portion +of the uncore on some non-coherent writes. Fill buffer propagation by itself +does not make stale data architecturally visible. Stale data must be propagated +to a location where it is subject to reading or sampling. + +Sideband Stale Data Propagator (SSDP) +------------------------------------- +The sideband stale data propagator (SSDP) is limited to the client (including +Intel Xeon server E3) uncore implementation. The sideband response buffer is +shared by all client cores. For non-coherent reads that go to sideband +destinations, the uncore logic returns 64 bytes of data to the core, including +both requested data and unrequested stale data, from a transaction buffer and +the sideband response buffer. As a result, stale data from the sideband +response and transaction buffers may now reside in a core fill buffer. + +Primary Stale Data Propagator (PSDP) +------------------------------------ +The primary stale data propagator (PSDP) is limited to the client (including +Intel Xeon server E3) uncore implementation. Similar to the sideband response +buffer, the primary response buffer is shared by all client cores. For some +processors, MMIO primary reads will return 64 bytes of data to the core fill +buffer including both requested data and unrequested stale data. This is +similar to the sideband stale data propagator. + +Vulnerabilities +=============== +Device Register Partial Write (DRPW) (CVE-2022-21166) +----------------------------------------------------- +Some endpoint MMIO registers incorrectly handle writes that are smaller than +the register size. Instead of aborting the write or only copying the correct +subset of bytes (for example, 2 bytes for a 2-byte write), more bytes than +specified by the write transaction may be written to the register. On +processors affected by FBSDP, this may expose stale data from the fill buffers +of the core that created the write transaction. + +Shared Buffers Data Sampling (SBDS) (CVE-2022-21125) +---------------------------------------------------- +After propagators may have moved data around the uncore and copied stale data +into client core fill buffers, processors affected by MFBDS can leak data from +the fill buffer. It is limited to the client (including Intel Xeon server E3) +uncore implementation. + +Shared Buffers Data Read (SBDR) (CVE-2022-21123) +------------------------------------------------ +It is similar to Shared Buffer Data Sampling (SBDS) except that the data is +directly read into the architectural software-visible state.

Therefore, VERW is not required for kernel/userspace. For +virtualization case, VERW is only needed at VMENTER for a guest with MMIO +capability. + +Mitigation points +----------------- +Return to user space +^^^^^^^^^^^^^^^^^^^^ +Same mitigation as MDS when affected by MDS/TAA, otherwise no mitigation +needed. + +C-State transition +^^^^^^^^^^^^^^^^^^ +Control register writes by CPU during C-state transition can propagate data +from fill buffer to uncore buffers.

On CPUs not affected by +MDS/TAA, guest without MMIO access cannot extract secrets using Processor MMIO +Stale Data vulnerabilities, so there is no need to execute VERW for such guests. + +Mitigation control on the kernel command line +--------------------------------------------- +The kernel command line allows to control the Processor MMIO Stale Data +mitigations at boot time with the option "mmio_stale_data=".

SPDX-License-Identifier: GPL-2.0 +.. include:: + +=============================================== +``amd-pstate`` CPU Performance Scaling Driver +=============================================== + +:Copyright: |copy| 2021 Advanced Micro Devices, Inc. + +:Author: Huang Rui + + +Introduction +=================== + +``amd-pstate`` is the AMD CPU performance scaling driver that introduces a +new CPU frequency control mechanism on modern AMD APU and CPU series in +Linux kernel. The new mechanism is based on Collaborative Processor +Performance Control (CPPC) which provides finer grain frequency management +than legacy ACPI hardware P-States. Current AMD CPU/APU platforms are using +the ACPI P-states driver to manage CPU frequency and clocks with switching +only in 3 P-states. CPPC replaces the ACPI P-states controls and allows a +flexible, low-latency interface for the Linux kernel to directly +communicate the performance hints to hardware. + +``amd-pstate`` leverages the Linux kernel governors such as ``schedutil``, +``ondemand``, etc. to manage the performance hints which are provided by +CPPC hardware functionality that internally follows the hardware +specification (for details refer to AMD64 Architecture Programmer's Manual +Volume 2: System Programming [1]_). Currently, ``amd-pstate`` supports basic +frequency control function according to kernel governors on some of the +Zen2 and Zen3 processors, and we will implement more AMD specific functions +in future after we verify them on the hardware and SBIOS. + + +AMD CPPC Overview +======================= + +Collaborative Processor Performance Control (CPPC) interface enumerates a +continuous, abstract, and unit-less performance value in a scale that is +not tied to a specific performance state / frequency. This is an ACPI +standard [2]_ which software can specify application performance goals and +hints as a relative target to the infrastructure limits. AMD processors +provide the low latency register model (MSR) instead of an AML code +interpreter for performance adjustments. ``amd-pstate`` will initialize a +``struct cpufreq_driver`` instance, ``amd_pstate_driver``, with the callbacks +to manage each performance update behavior. :: + + Highest Perf ------>+-----------------------+ +-----------------------+ + | | | | + | | | | + | | Max Perf ---->| | + | | | | + | | | | + Nominal Perf ------>+-----------------------+ +-----------------------+ + | | | | + | | | | + | | | | + | | | | + | | | | + | | | | + | | Desired Perf ---->| | + | | | | + | | | | + | | | | + | | | | + | | | | + | | | | + | | | | + | | | | + | | | | + Lowest non- | | | | + linear perf ------>+-----------------------+ +-----------------------+ + | | | | + | | Lowest perf ---->| | + | | | | + Lowest perf ------>+-----------------------+ +-----------------------+ + | | | | + | | | | + | | | | + 0 ------>+-----------------------+ +-----------------------+ + + AMD P-States Performance Scale + + +.. _perf_cap: + +AMD CPPC Performance Capability +-------------------------------- + +Highest Performance (RO) +......................... + +This is the absolute maximum performance an individual processor may reach, +assuming ideal conditions. This performance level may not be sustainable +for long durations and may only be achievable if other platform components +are in a specific state; for example, it may require other processors to be in +an idle state. This would be equivalent to the highest frequencies +supported by the processor. + +Nominal (Guaranteed) Performance (RO) +...................................... + +This is the maximum sustained performance level of the processor, assuming +ideal operating conditions. In the absence of an external constraint (power, +thermal, etc.), this is the performance level the processor is expected to +be able to maintain continuously. All cores/processors are expected to be +able to sustain their nominal performance state simultaneously. + +Lowest non-linear Performance (RO) +................................... + +This is the lowest performance level at which nonlinear power savings are +achieved, for example, due to the combined effects of voltage and frequency +scaling. Above this threshold, lower performance levels should be generally +more energy efficient than higher performance levels. This register +effectively conveys the most efficient performance level to ``amd-pstate``. + +Lowest Performance (RO) +........................ + +This is the absolute lowest performance level of the processor. Selecting a +performance level lower than the lowest nonlinear performance level may +cause an efficiency penalty but should reduce the instantaneous power +consumption of the processor. + +AMD CPPC Performance Control +------------------------------ + +``amd-pstate`` passes performance goals through these registers. The +register drives the behavior of the desired performance target. + +Minimum requested performance (RW) +................................... + +``amd-pstate`` specifies the minimum allowed performance level. + +Maximum requested performance (RW) +................................... + +``amd-pstate`` specifies a limit the maximum performance that is expected +to be supplied by the hardware. + +Desired performance target (RW) +................................... + +``amd-pstate`` specifies a desired target in the CPPC performance scale as +a relative number. This can be expressed as percentage of nominal +performance (infrastructure max). Below the nominal sustained performance +level, desired performance expresses the average performance level of the +processor subject to hardware. Above the nominal performance level, +the processor must provide at least nominal performance requested and go higher +if current operating conditions allow. + +Energy Performance Preference (EPP) (RW) +......................................... + +This attribute provides a hint to the hardware if software wants to bias +toward performance (0x0) or energy efficiency (0xff). + + +Key Governors Support +======================= + +``amd-pstate`` can be used with all the (generic) scaling governors listed +by the ``scaling_available_governors`` policy attribute in ``sysfs``. Then, +it is responsible for the configuration of policy objects corresponding to +CPUs and provides the ``CPUFreq`` core (and the scaling governors attached +to the policy objects) with accurate information on the maximum and minimum +operating frequencies supported by the hardware. Users can check the +``scaling_cur_freq`` information comes from the ``CPUFreq`` core. + +``amd-pstate`` mainly supports ``schedutil`` and ``ondemand`` for dynamic +frequency control. It is to fine tune the processor configuration on +``amd-pstate`` to the ``schedutil`` with CPU CFS scheduler. ``amd-pstate`` +registers the adjust_perf callback to implement performance update behavior +similar to CPPC. It is initialized by ``sugov_start`` and then populates the +CPU's update_util_data pointer to assign ``sugov_update_single_perf`` as the +utilization update callback function in the CPU scheduler. The CPU scheduler +will call ``cpufreq_update_util`` and assigns the target performance according +to the ``struct sugov_cpu`` that the utilization update belongs to. +Then, ``amd-pstate`` updates the desired performance according to the CPU +scheduler assigned. + +.. _processor_support: + +Processor Support +======================= + +The ``amd-pstate`` initialization will fail if the ``_CPC`` entry in the ACPI +SBIOS does not exist in the detected processor. It uses ``acpi_cpc_valid`` +to check the existence of ``_CPC``. All Zen based processors support the legacy +ACPI hardware P-States function, so when ``amd-pstate`` fails initialization, +the kernel will fall back to initialize the ``acpi-cpufreq`` driver. + +There are two types of hardware implementations for ``amd-pstate``: one is +`Full MSR Support `_ and another is `Shared Memory Support +`_. It can use the :c:macro:`X86_FEATURE_CPPC` feature flag to +indicate the different types. (For details, refer to the Processor Programming +Reference (PPR) for AMD Family 19h Model 51h, Revision A1 Processors [3]_.) +``amd-pstate`` is to register different ``static_call`` instances for different +hardware implementations. + +Currently, some of the Zen2 and Zen3 processors support ``amd-pstate``. In the +future, it will be supported on more and more AMD processors. + +Full MSR Support +----------------- + +Some new Zen3 processors such as Cezanne provide the MSR registers directly +while the :c:macro:`X86_FEATURE_CPPC` CPU feature flag is set. +``amd-pstate`` can handle the MSR register to implement the fast switch +function in ``CPUFreq`` that can reduce the latency of frequency control in +interrupt context. The functions with a ``pstate_xxx`` prefix represent the +operations on MSR registers. + +Shared Memory Support +---------------------- + +If the :c:macro:`X86_FEATURE_CPPC` CPU feature flag is not set, the +processor supports the shared memory solution. In this case, ``amd-pstate`` +uses the ``cppc_acpi`` helper methods to implement the callback functions +that are defined on ``static_call``. The functions with the ``cppc_xxx`` prefix +represent the operations of ACPI CPPC helpers for the shared memory solution. + + +AMD P-States and ACPI hardware P-States always can be supported in one +processor. But AMD P-States has the higher priority and if it is enabled +with :c:macro:`MSR_AMD_CPPC_ENABLE` or ``cppc_set_enable``, it will respond +to the request from AMD P-States. + + +User Space Interface in ``sysfs`` +================================== + +``amd-pstate`` exposes several global attributes (files) in ``sysfs`` to +control its functionality at the system level.

That is, fine-grained and continuous frequency ranges +instead of the legacy hardware P-states. ``amd-pstate`` is the kernel +module which supports the new AMD P-States mechanism on most of the future AMD +platforms. The AMD P-States mechanism is the more performance and energy +efficiency frequency management method on AMD processors. + +Kernel Module Options for ``amd-pstate`` +========================================= + +Passive Mode +------------ + +``amd_pstate=passive`` + +It will be enabled if the ``amd_pstate=passive`` is passed to the kernel in the command line. +In this mode, ``amd_pstate`` driver software specifies a desired QoS target in the CPPC +performance scale as a relative number. This can be expressed as percentage of nominal +performance (infrastructure max). Below the nominal sustained performance level, +desired performance expresses the average performance level of the processor subject +to the Performance Reduction Tolerance register. Above the nominal performance level, +processor must provide at least nominal performance requested and go higher if current +operating conditions allow. + + +``cpupower`` tool support for ``amd-pstate`` +=============================================== + +``amd-pstate`` is supported by the ``cpupower`` tool, which can be used to dump +frequency information.

Adding many original ideas, approaches, +improvements and implementations, it became totally different from +Unionfs while keeping the basic features. +Later, Unionfs Version 2.x series began taking some of the same +approaches to aufs1's. +Unionfs was being developed by Professor Erez Zadok at Stony Brook +University and his team. + +Aufs5 supports linux-v5.0 and later, If you want older kernel version +support, +- for linux-v4.x series, try aufs4-linux.git or aufs4-standalone.git +- for linux-v3.x series, try aufs3-linux.git or aufs3-standalone.git +- for linux-v2.6.16 and later, try aufs2-2.6.git, aufs2-standalone.git + or aufs1 from CVS on SourceForge. + +Note: it becomes clear that "Aufs was rejected.

Download +---------------------------------------- +There are three GIT trees for aufs5, aufs5-linux.git, +aufs5-standalone.git, and aufs-util.git. Note that there is no "5" in +"aufs-util.git." +While the aufs-util is always necessary, you need either of aufs5-linux +or aufs5-standalone. + +The aufs5-linux tree includes the whole linux mainline GIT tree, +git://git.kernel.org/.../torvalds/linux.git. +And you cannot select CONFIG_AUFS_FS=m for this version, eg. you cannot +build aufs5 as an external kernel module. +Several extra patches are not included in this tree. Only +aufs5-standalone tree contains them. They are described in the later +section "Configuration and Compilation." + +On the other hand, the aufs5-standalone tree has only aufs source files +and necessary patches, and you can select CONFIG_AUFS_FS=m. +But you need to apply all aufs patches manually. + +You will find GIT branches whose name is in form of "aufs5.x" where "x" +represents the linux kernel version, "linux-5.x". For instance, +"aufs5.0" is for linux-5.0. For latest "linux-5.x-rcN", use +"aufs5.x-rcN" branch. + +o aufs5-linux tree +$ git clone --reference /your/linux/git/tree \ + git://github.com/sfjro/aufs5-linux.git aufs5-linux.git +- if you don't have linux GIT tree, then remove "--reference ..." +$ cd aufs5-linux.git +$ git checkout origin/aufs5.0 + +Or You may want to directly git-pull aufs into your linux GIT tree, and +leave the patch-work to GIT. +$ cd /your/linux/git/tree +$ git remote add aufs5 git://github.com/sfjro/aufs5-linux.git +$ git fetch aufs5 +$ git checkout -b my5.0 v5.0 +$ (add your local change...) +$ git pull aufs5 aufs5.0 +- now you have v5.0 + your_changes + aufs5.0 in you my5.0 branch. +- you may need to solve some conflicts between your_changes and + aufs5.0. in this case, git-rerere is recommended so that you can + solve the similar conflicts automatically when you upgrade to 5.1 or + later in the future. + +o aufs5-standalone tree +$ git clone git://github.com/sfjro/aufs5-standalone.git aufs5-standalone.git +$ cd aufs5-standalone.git +$ git checkout origin/aufs5.0 + +o aufs-util tree +$ git clone git://git.code.sf.net/p/aufs/aufs-util aufs-util.git +- note that the public aufs-util.git is on SourceForge instead of + GitHUB. +$ cd aufs-util.git +$ git checkout origin/aufs5.0 + +Note: The 5.x-rcN branch is to be used with `rc' kernel versions ONLY. +The minor version number, 'x' in '5.x', of aufs may not always +follow the minor version number of the kernel. +Because changes in the kernel that cause the use of a new +minor version number do not always require changes to aufs-util. + +Since aufs-util has its own minor version number, you may not be +able to find a GIT branch in aufs-util for your kernel's +exact minor version number. +In this case, you should git-checkout the branch for the +nearest lower number. + +For (an unreleased) example: +If you are using "linux-5.10" and the "aufs5.10" branch +does not exist in aufs-util repository, then "aufs5.9", "aufs5.8" +or something numerically smaller is the branch for your kernel. + +Also you can view all branches by + $ git branch -a + + +3. Configuration and Compilation +---------------------------------------- +Make sure you have git-checkout'ed the correct branch. + +For aufs5-linux tree, +- enable CONFIG_AUFS_FS. +- set other aufs configurations if necessary. +- for aufs5.13 and later + Because aufs is not only an ordinary filesystem (callee of VFS), but + also a caller of VFS functions for branch filesystems, subclassing of + the internal locks for LOCKDEP is necessary.

Here are what I use on my + test environment. + CONFIG_LOCKDEP_BITS=21 + CONFIG_LOCKDEP_CHAINS_BITS=21 + CONFIG_LOCKDEP_STACK_TRACE_BITS=24 + +For aufs5-standalone tree, +There are several ways to build. + +1. +- apply ./aufs5-kbuild.patch to your kernel source files. +- apply ./aufs5-base.patch too. +- apply ./aufs5-mmap.patch too. +- apply ./aufs5-standalone.patch too, if you have a plan to set + CONFIG_AUFS_FS=m. otherwise you don't need ./aufs5-standalone.patch. +- copy ./{Documentation,fs,include/uapi/linux/aufs_type.h} files to your + kernel source tree. Never copy $PWD/include/uapi/linux/Kbuild. +- enable CONFIG_AUFS_FS, you can select either + =m or =y. +- and build your kernel as usual. +- install the built kernel. +- install the header files too by "make headers_install" to the + directory where you specify. By default, it is $PWD/usr. + "make help" shows a brief note for headers_install. +- and reboot your system. + +2. +- module only (CONFIG_AUFS_FS=m). +- apply ./aufs5-base.patch to your kernel source files. +- apply ./aufs5-mmap.patch too. +- apply ./aufs5-standalone.patch too. +- build your kernel, don't forget "make headers_install", and reboot. +- edit ./config.mk and set other aufs configurations if necessary. + Note: You should read $PWD/fs/aufs/Kconfig carefully which describes + every aufs configurations. +- build the module by simple "make". +- you can specify ${KDIR} make variable which points to your kernel + source tree. +- install the files + + run "make install" to install the aufs module, or copy the built + $PWD/aufs.ko to /lib/modules/... and run depmod -a (or reboot simply). + + run "make install_headers" (instead of headers_install) to install + the modified aufs header file (you can specify DESTDIR which is + available in aufs standalone version's Makefile only), or copy + $PWD/usr/include/linux/aufs_type.h to /usr/include/linux or wherever + you like manually. By default, the target directory is $PWD/usr. +- no need to apply aufs5-kbuild.patch, nor copying source files to your + kernel source tree. + +Note: The header file aufs_type.h is necessary to build aufs-util + as well as "make headers_install" in the kernel source tree. + headers_install is subject to be forgotten, but it is essentially + necessary, not only for building aufs-util. + You may not meet problems without headers_install in some older + version though. + +And then, +- read README in aufs-util, build and install it +- note that your distribution may contain an obsoleted version of + aufs_type.h in /usr/include/linux or something. When you build aufs + utilities, make sure that your compiler refers the correct aufs header + file which is built by "make headers_install." +- if you want to use readdir(3) in userspace or pathconf(3) wrapper, + then run "make install_ulib" too. And refer to the aufs manual in + detail. + +There several other patches in aufs5-standalone.git. They are all +optional. When you meet some problems, they will help you. +- aufs5-loopback.patch + Supports a nested loopback mount in a branch-fs. This patch is + unnecessary until aufs produces a message like "you may want to try + another patch for loopback file". +- vfs-ino.patch + Modifies a system global kernel internal function get_next_ino() in + order to stop assigning 0 for an inode-number. Not directly related to + aufs, but recommended generally. +- tmpfs-idr.patch + Keeps the tmpfs inode number as the lowest value. Effective to reduce + the size of aufs XINO files for tmpfs branch. Also it prevents the + duplication of inode number, which is important for backup tools and + other utilities. When you find aufs XINO files for tmpfs branch + growing too much, try this patch. + + +4. Usage +---------------------------------------- +At first, make sure aufs-util are installed, and please read the aufs +manual, aufs.5 in aufs-util.git tree. +$ man -l aufs.5 + +And then, +$ mkdir /tmp/rw /tmp/aufs +# mount -t aufs -o br=/tmp/rw:${HOME} none /tmp/aufs + +Here is another example. The result is equivalent. +# mount -t aufs -o br=/tmp/rw=rw:${HOME}=ro none /tmp/aufs + Or +# mount -t aufs -o br:/tmp/rw none /tmp/aufs +# mount -o remount,append:${HOME} /tmp/aufs + +Then, you can see whole tree of your home dir through /tmp/aufs. If +you modify a file under /tmp/aufs, the one on your home directory is +not affected, instead the same named file will be newly created under +/tmp/rw. And all of your modification to a file will be applied to +the one under /tmp/rw. This is called the file based Copy on Write +(COW) method. +Aufs mount options are described in aufs.5. +If you run chroot or something and make your aufs as a root directory, +then you need to customize the shutdown script. See the aufs manual in +detail. + +Additionally, there are some sample usages of aufs which are a +diskless system with network booting, and LiveCD over NFS. +See sample dir in CVS tree on SourceForge. + + +5.

"Butter aufs Brot"(G) means "butter onto bread"(E). + But "Filesystem aufs Filesystem" is hard to understand. +4. abbrev. for "African Urban Fashion Show". + +AUFS is a filesystem with features: +- multi layered stackable unification filesystem, the member directory + is called as a branch. +- branch permission and attribute, 'readonly', 'real-readonly', + 'readwrite', 'whiteout-able', 'link-able whiteout', etc. and their + combination. +- internal "file copy-on-write". +- logical deletion, whiteout. +- dynamic branch manipulation, adding, deleting and changing permission. +- allow bypassing aufs, user's direct branch access. +- external inode number translation table and bitmap which maintains the + persistent aufs inode number. +- seekable directory, including NFS readdir. +- file mapping, mmap and sharing pages. +- pseudo-link, hardlink over branches. +- loopback mounted filesystem as a branch. +- several policies to select one among multiple writable branches. +- revert a single systemcall when an error occurs in aufs. +- and more... + + +Multi Layered Stackable Unification Filesystem +---------------------------------------------------------------------- +Most people already knows what it is. +It is a filesystem which unifies several directories and provides a +merged single directory. When users access a file, the access will be +passed/re-directed/converted (sorry, I am not sure which English word is +correct) to the real file on the member filesystem. The member +filesystem is called 'lower filesystem' or 'branch' and has a mode +'readonly' and 'readwrite.' And the deletion for a file on the lower +readonly branch is handled by creating 'whiteout' on the upper writable +branch. + +On LKML, there have been discussions about UnionMount (Jan Blunck, +Bharata B Rao and Valerie Aurora) and Unionfs (Erez Zadok). They took +different approaches to implement the merged-view. +The former tries putting it into VFS, and the latter implements as a +separate filesystem. +(If I misunderstand about these implementations, please let me know and +I shall correct it. Because it is a long time ago when I read their +source files last time). + +UnionMount's approach will be able to small, but may be hard to share +branches between several UnionMount since the whiteout in it is +implemented in the inode on branch filesystem and always +shared. According to Bharata's post, readdir does not seems to be +finished yet. +There are several missing features known in this implementations such as +- for users, the inode number may change silently. eg. copy-up. +- link(2) may break by copy-up. +- read(2) may get an obsoleted filedata (fstat(2) too). +- fcntl(F_SETLK) may be broken by copy-up. +- unnecessary copy-up may happen, for example mmap(MAP_PRIVATE) after + open(O_RDWR). + +In linux-3.18, "overlay" filesystem (formerly known as "overlayfs") was +merged into mainline. This is another implementation of UnionMount as a +separated filesystem. All the limitations and known problems which +UnionMount are equally inherited to "overlay" filesystem. + +Unionfs has a longer history. When I started implementing a stackable +filesystem (Aug 2005), it already existed. It has virtual super_block, +inode, dentry and file objects and they have an array pointing lower +same kind objects. After contributing many patches for Unionfs, I +re-started my project AUFS (Jun 2006). + +In AUFS, the structure of filesystem resembles to Unionfs, but I +implemented my own ideas, approaches and enhancements and it became +totally different one. + +Comparing DM snapshot and fs based implementation +- the number of bytes to be copied between devices is much smaller. +- the type of filesystem must be one and only. +- the fs must be writable, no readonly fs, even for the lower original + device. so the compression fs will not be usable. but if we use + loopback mount, we may address this issue. + for instance, + mount /cdrom/squashfs.img /sq + losetup /sq/ext2.img + losetup /somewhere/cow + dmsetup "snapshot /dev/loop0 /dev/loop1 ..." +- it will be difficult (or needs more operations) to extract the + difference between the original device and COW. +- DM snapshot-merge may help a lot when users try merging. in the + fs-layer union, users will use rsync(1). + +You may want to read my old paper "Filesystems in LiveCD" +(http://aufs.sourceforge.net/aufs2/report/sq/sq.pdf). + + +Several characters/aspects/persona of aufs +---------------------------------------------------------------------- + +Aufs has several characters, aspects or persona. +1. a filesystem, callee of VFS helper +2. sub-VFS, caller of VFS helper for branches +3. a virtual filesystem which maintains persistent inode number +4. reader/writer of files on branches such like an application + +1. Callee of VFS Helper +As an ordinary linux filesystem, aufs is a callee of VFS. For instance, +unlink(2) from an application reaches sys_unlink() kernel function and +then vfs_unlink() is called. vfs_unlink() is one of VFS helper and it +calls filesystem specific unlink operation. Actually aufs implements the +unlink operation but it behaves like a redirector. + +2. Caller of VFS Helper for Branches +aufs_unlink() passes the unlink request to the branch filesystem as if +it were called from VFS. So the called unlink operation of the branch +filesystem acts as usual. As a caller of VFS helper, aufs should handle +every necessary pre/post operation for the branch filesystem. +- acquire the lock for the parent dir on a branch +- lookup in a branch +- revalidate dentry on a branch +- mnt_want_write() for a branch +- vfs_unlink() for a branch +- mnt_drop_write() for a branch +- release the lock on a branch + +3. Persistent Inode Number +One of the most important issue for a filesystem is to maintain inode +numbers. This is particularly important to support exporting a +filesystem via NFS. Aufs is a virtual filesystem which doesn't have a +backend block device for its own. But some storage is necessary to +keep and maintain the inode numbers. It may be a large space and may not +suit to keep in memory. Aufs rents some space from its first writable +branch filesystem (by default) and creates file(s) on it. These files +are created by aufs internally and removed soon (currently) keeping +opened. +Note: Because these files are removed, they are totally gone after + unmounting aufs. It means the inode numbers are not persistent + across unmount or reboot. I have a plan to make them really + persistent which will be important for aufs on NFS server. + +4. Read/Write Files Internally (copy-on-write) +Because a branch can be readonly, when you write a file on it, aufs will +"copy-up" it to the upper writable branch internally. And then write the +originally requested thing to the file. Generally kernel doesn't +open/read/write file actively. In aufs, even a single write may cause a +internal "file copy". This behaviour is very similar to cp(1) command. + +Some people may think it is better to pass such work to user space +helper, instead of doing in kernel space. Actually I am still thinking +about it. But currently I have implemented it in kernel space. --- linux-5.15.0.orig/Documentation/filesystems/aufs/design/02struct.txt +++ linux-5.15.0/Documentation/filesystems/aufs/design/02struct.txt @@ -0,0 +1,258 @@ + +# Copyright (C) 2005-2021 Junjiro R.

All these objects have a +dynamically allocated array and store the same kind of pointers to the +lower filesystem, branch. +For example, when you build a union with one readwrite branch and one +readonly, mounted /au, /rw and /ro respectively. +- /au = /rw + /ro +- /ro/fileA exists but /rw/fileA + +Aufs lookup operation finds /ro/fileA and gets dentry for that. These +pointers are stored in a aufs dentry. The array in aufs dentry will be, +- [0] = NULL (because /rw/fileA doesn't exist) +- [1] = /ro/fileA + +This style of an array is essentially same to the aufs +superblock/inode/dentry/file objects. + +Because aufs supports manipulating branches, ie. add/delete/change +branches dynamically, these objects has its own generation. When +branches are changed, the generation in aufs superblock is +incremented. And a generation in other object are compared when it is +accessed. When a generation in other objects are obsoleted, aufs +refreshes the internal array. + + +Superblock +---------------------------------------------------------------------- +Additionally aufs superblock has some data for policies to select one +among multiple writable branches, XIB files, pseudo-links and kobject. +See below in detail. +About the policies which supports copy-down a directory, see +wbr_policy.txt too. + + +Branch and XINO(External Inode Number Translation Table) +---------------------------------------------------------------------- +Every branch has its own xino (external inode number translation table) +file. The xino file is created and unlinked by aufs internally. When two +members of a union exist on the same filesystem, they share the single +xino file. +The struct of a xino file is simple, just a sequence of aufs inode +numbers which is indexed by the lower inode number. +In the above sample, assume the inode number of /ro/fileA is i111 and +aufs assigns the inode number i999 for fileA. Then aufs writes 999 as +4(8) bytes at 111 * 4(8) bytes offset in the xino file. + +When the inode numbers are not contiguous, the xino file will be sparse +which has a hole in it and doesn't consume as much disk space as it +might appear. If your branch filesystem consumes disk space for such +holes, then you should specify 'xino=' option at mounting aufs. + +Aufs has a mount option to free the disk blocks for such holes in XINO +files on tmpfs or ramdisk. But it is not so effective actually. If you +meet a problem of disk shortage due to XINO files, then you should try +"tmpfs-ino.patch" (and "vfs-ino.patch" too) in aufs4-standalone.git. +The patch localizes the assignment inumbers per tmpfs-mount and avoid +the holes in XINO files. + +Also a writable branch has three kinds of "whiteout bases". All these +are existed when the branch is joined to aufs, and their names are +whiteout-ed doubly, so that users will never see their names in aufs +hierarchy. +1. a regular file which will be hardlinked to all whiteouts. +2. a directory to store a pseudo-link. +3. a directory to store an "orphan"-ed file temporary. + +1. Whiteout Base + When you remove a file on a readonly branch, aufs handles it as a + logical deletion and creates a whiteout on the upper writable branch + as a hardlink of this file in order not to consume inode on the + writable branch. +2. Pseudo-link Dir + See below, Pseudo-link. +3. Step-Parent Dir + When "fileC" exists on the lower readonly branch only and it is + opened and removed with its parent dir, and then user writes + something into it, then aufs copies-up fileC to this + directory. Because there is no other dir to store fileC. After + creating a file under this dir, the file is unlinked. + +Because aufs supports manipulating branches, ie. add/delete/change +dynamically, a branch has its own id. When the branch order changes, +aufs finds the new index by searching the branch id. + + +Pseudo-link +---------------------------------------------------------------------- +Assume "fileA" exists on the lower readonly branch only and it is +hardlinked to "fileB" on the branch. When you write something to fileA, +aufs copies-up it to the upper writable branch. Additionally aufs +creates a hardlink under the Pseudo-link Directory of the writable +branch. The inode of a pseudo-link is kept in aufs super_block as a +simple list. If fileB is read after unlinking fileA, aufs returns +filedata from the pseudo-link instead of the lower readonly +branch. Because the pseudo-link is based upon the inode, to keep the +inode number by xino (see above) is essentially necessary. + +All the hardlinks under the Pseudo-link Directory of the writable branch +should be restored in a proper location later. Aufs provides a utility +to do this. The userspace helpers executed at remounting and unmounting +aufs by default. +During this utility is running, it puts aufs into the pseudo-link +maintenance mode. In this mode, only the process which began the +maintenance mode (and its child processes) is allowed to operate in +aufs. Some other processes which are not related to the pseudo-link will +be allowed to run too, but the rest have to return an error or wait +until the maintenance mode ends. If a process already acquires an inode +mutex (in VFS), it has to return an error. + + +XIB(external inode number bitmap) +---------------------------------------------------------------------- +Addition to the xino file per a branch, aufs has an external inode number +bitmap in a superblock object. It is also an internal file such like a +xino file. +It is a simple bitmap to mark whether the aufs inode number is in-use or +not. +To reduce the file I/O, aufs prepares a single memory page to cache xib. + +As well as XINO files, aufs has a feature to truncate/refresh XIB to +reduce the number of consumed disk blocks for these files. + + +Virtual or Vertical Dir, and Readdir in Userspace +---------------------------------------------------------------------- +In order to support multiple layers (branches), aufs readdir operation +constructs a virtual dir block on memory. For readdir, aufs calls +vfs_readdir() internally for each dir on branches, merges their entries +with eliminating the whiteout-ed ones, and sets it to file (dir) +object. So the file object has its entry list until it is closed. The +entry list will be updated when the file position is zero and becomes +obsoleted. This decision is made in aufs automatically. + +The dynamically allocated memory block for the name of entries has a +unit of 512 bytes (by default) and stores the names contiguously (no +padding). Another block for each entry is handled by kmem_cache too. +During building dir blocks, aufs creates hash list and judging whether +the entry is whiteouted by its upper branch or already listed. +The merged result is cached in the corresponding inode object and +maintained by a customizable life-time option. + +Some people may call it can be a security hole or invite DoS attack +since the opened and once readdir-ed dir (file object) holds its entry +list and becomes a pressure for system memory. But I'd say it is similar +to files under /proc or /sys. The virtual files in them also holds a +memory page (generally) while they are opened. When an idea to reduce +memory for them is introduced, it will be applied to aufs too. +For those who really hate this situation, I've developed readdir(3) +library which operates this merging in userspace. You just need to set +LD_PRELOAD environment variable, and aufs will not consume no memory in +kernel space for readdir(3). + + +Workqueue +---------------------------------------------------------------------- +Aufs sometimes requires privilege access to a branch. For instance, +in copy-up/down operation. When a user process is going to make changes +to a file which exists in the lower readonly branch only, and the mode +of one of ancestor directories may not be writable by a user +process. Here aufs copy-up the file with its ancestors and they may +require privilege to set its owner/group/mode/etc. +This is a typical case of a application character of aufs (see +Introduction). + +Aufs uses workqueue synchronously for this case. It creates its own +workqueue. The workqueue is a kernel thread and has privilege. Aufs +passes the request to call mkdir or write (for example), and wait for +its completion. This approach solves a problem of a signal handler +simply. +If aufs didn't adopt the workqueue and changed the privilege of the +process, then the process may receive the unexpected SIGXFSZ or other +signals. + +Also aufs uses the system global workqueue ("events" kernel thread) too +for asynchronous tasks, such like handling inotify/fsnotify, re-creating a +whiteout base and etc. This is unrelated to a privilege. +Most of aufs operation tries acquiring a rw_semaphore for aufs +superblock at the beginning, at the same time waits for the completion +of all queued asynchronous tasks. + + +Whiteout +---------------------------------------------------------------------- +The whiteout in aufs is very similar to Unionfs's. That is represented +by its filename. UnionMount takes an approach of a file mode, but I am +afraid several utilities (find(1) or something) will have to support it. + +Basically the whiteout represents "logical deletion" which stops aufs to +lookup further, but also it represents "dir is opaque" which also stop +further lookup. + +In aufs, rmdir(2) and rename(2) for dir uses whiteout alternatively. +In order to make several functions in a single systemcall to be +revertible, aufs adopts an approach to rename a directory to a temporary +unique whiteouted name. +For example, in rename(2) dir where the target dir already existed, aufs +renames the target dir to a temporary unique whiteouted name before the +actual rename on a branch, and then handles other actions (make it opaque, +update the attributes, etc). If an error happens in these actions, aufs +simply renames the whiteouted name back and returns an error. If all are +succeeded, aufs registers a function to remove the whiteouted unique +temporary name completely and asynchronously to the system global +workqueue. + + +Copy-up +---------------------------------------------------------------------- +It is a well-known feature or concept. +When user modifies a file on a readonly branch, aufs operate "copy-up" +internally and makes change to the new file on the upper writable branch. +When the trigger systemcall does not update the timestamps of the parent +dir, aufs reverts it after copy-up. + + +Move-down (aufs3.9 and later) +---------------------------------------------------------------------- +"Copy-up" is one of the essential feature in aufs. It copies a file from +the lower readonly branch to the upper writable branch when a user +changes something about the file. +"Move-down" is an opposite action of copy-up. Basically this action is +ran manually instead of automatically and internally. +For desgin and implementation, aufs has to consider these issues. +- whiteout for the file may exist on the lower branch. +- ancestor directories may not exist on the lower branch. +- diropq for the ancestor directories may exist on the upper branch. +- free space on the lower branch will reduce. +- another access to the file may happen during moving-down, including + UDBA (see "Revalidate Dentry and UDBA"). +- the file should not be hard-linked nor pseudo-linked. they should be + handled by auplink utility later. + +Sometimes users want to move-down a file from the upper writable branch +to the lower readonly or writable branch. For instance, +- the free space of the upper writable branch is going to run out. +- create a new intermediate branch between the upper and lower branch. +- etc. + +For this purpose, use "aumvdown" command in aufs-util.git. --- linux-5.15.0.orig/Documentation/filesystems/aufs/design/03atomic_open.txt +++ linux-5.15.0/Documentation/filesystems/aufs/design/03atomic_open.txt @@ -0,0 +1,85 @@ + +# Copyright (C) 2015-2021 Junjiro R.

If not, see . + +Lookup in a Branch +---------------------------------------------------------------------- +Since aufs has a character of sub-VFS (see Introduction), it operates +lookup for branches as VFS does. It may be a heavy work. But almost all +lookup operation in aufs is the simplest case, ie. lookup only an entry +directly connected to its parent. Digging down the directory hierarchy +is unnecessary. VFS has a function lookup_one_len() for that use, and +aufs calls it. + +When a branch is a remote filesystem, aufs basically relies upon its +->d_revalidate(), also aufs forces the hardest revalidate tests for +them. +For d_revalidate, aufs implements three levels of revalidate tests. See +"Revalidate Dentry and UDBA" in detail. + + +Test Only the Highest One for the Directory Permission (dirperm1 option) +---------------------------------------------------------------------- +Let's try case study. +- aufs has two branches, upper readwrite and lower readonly. + /au = /rw + /ro +- "dirA" exists under /ro, but /rw. and its mode is 0700. +- user invoked "chmod a+rx /au/dirA" +- the internal copy-up is activated and "/rw/dirA" is created and its + permission bits are set to world readable. +- then "/au/dirA" becomes world readable? + +In this case, /ro/dirA is still 0700 since it exists in readonly branch, +or it may be a natively readonly filesystem. If aufs respects the lower +branch, it should not respond readdir request from other users. But user +allowed it by chmod. Should really aufs rejects showing the entries +under /ro/dirA? + +To be honest, I don't have a good solution for this case. So aufs +implements 'dirperm1' and 'nodirperm1' mount options, and leave it to +users. +When dirperm1 is specified, aufs checks only the highest one for the +directory permission, and shows the entries. Otherwise, as usual, checks +every dir existing on all branches and rejects the request. + +As a side effect, dirperm1 option improves the performance of aufs +because the number of permission check is reduced when the number of +branch is many. + + +Revalidate Dentry and UDBA (User's Direct Branch Access) +---------------------------------------------------------------------- +Generally VFS helpers re-validate a dentry as a part of lookup. +0. digging down the directory hierarchy. +1. lock the parent dir by its i_mutex. +2. lookup the final (child) entry. +3. revalidate it. +4. call the actual operation (create, unlink, etc.) +5. unlock the parent dir + +If the filesystem implements its ->d_revalidate() (step 3), then it is +called. Actually aufs implements it and checks the dentry on a branch is +still valid. +But it is not enough. Because aufs has to release the lock for the +parent dir on a branch at the end of ->lookup() (step 2) and +->d_revalidate() (step 3) while the i_mutex of the aufs dir is still +held by VFS. +If the file on a branch is changed directly, eg. bypassing aufs, after +aufs released the lock, then the subsequent operation may cause +something unpleasant result. + +This situation is a result of VFS architecture, ->lookup() and +->d_revalidate() is separated. But I never say it is wrong. It is a good +design from VFS's point of view. It is just not suitable for sub-VFS +character in aufs. + +Aufs supports such case by three level of revalidation which is +selectable by user. +1. Simple Revalidate + Addition to the native flow in VFS's, confirm the child-parent + relationship on the branch just after locking the parent dir on the + branch in the "actual operation" (step 4). When this validation + fails, aufs returns EBUSY. ->d_revalidate() (step 3) in aufs still + checks the validation of the dentry on branches. +2. Monitor Changes Internally by Inotify/Fsnotify + Addition to above, in the "actual operation" (step 4) aufs re-lookup + the dentry on the branch, and returns EBUSY if it finds different + dentry. + Additionally, aufs sets the inotify/fsnotify watch for every dir on branches + during it is in cache. When the event is notified, aufs registers a + function to kernel 'events' thread by schedule_work(). And the + function sets some special status to the cached aufs dentry and inode + private data. If they are not cached, then aufs has nothing to + do. When the same file is accessed through aufs (step 0-3) later, + aufs will detect the status and refresh all necessary data. + In this mode, aufs has to ignore the event which is fired by aufs + itself. +3. No Extra Validation + This is the simplest test and doesn't add any additional revalidation + test, and skip the revalidation in step 4. It is useful and improves + aufs performance when system surely hide the aufs branches from user, + by over-mounting something (or another method). --- linux-5.15.0.orig/Documentation/filesystems/aufs/design/04branch.txt +++ linux-5.15.0/Documentation/filesystems/aufs/design/04branch.txt @@ -0,0 +1,74 @@ + +# Copyright (C) 2005-2021 Junjiro R.

By default, the highest +writable branch which has the parent (or ancestor) dir of the target +file is chosen (top-down-parent policy). +By user's request, aufs implements some other policies to select the +writable branch, for file creation several policies, round-robin, +most-free-space, and other policies.

Since a single cached aufs dentry may +contains two names, before- and after-rename, the name comparision in +UDBA handler may not work correctly. In this case, the behaviour will be +equivalen to udba=reval case. --- linux-5.15.0.orig/Documentation/filesystems/aufs/design/06fhsm.txt +++ linux-5.15.0/Documentation/filesystems/aufs/design/06fhsm.txt @@ -0,0 +1,120 @@ + +# Copyright (C) 2011-2021 Junjiro R.

Aufs provides this feature as file-based with multiple +writable branches, based upon the principle of "Colder, the Lower". +Here the word "colder" means that the less used files, and "lower" means +that the position in the order of the stacked branches vertically. +These multiple writable branches are prioritized, ie. the topmost one +should be the fastest drive and be used heavily. + +o Characters in aufs FHSM story +- aufs itself and a new branch attribute. +- a new ioctl interface to move-down and to establish a connection with + the daemon ("move-down" is a converse of "copy-up"). +- userspace tool and daemon. + +The userspace daemon establishes a connection with aufs and waits for +the notification. The notified information is very similar to struct +statfs containing the number of consumed blocks and inodes. +When the consumed blocks/inodes of a branch exceeds the user-specified +upper watermark, the daemon activates its move-down process until the +consumed blocks/inodes reaches the user-specified lower watermark. + +The actual move-down is done by aufs based upon the request from +user-space since we need to maintain the inode number and the internal +pointer arrays in aufs. + +Currently aufs FHSM handles the regular files only. Additionally they +must not be hard-linked nor pseudo-linked. + + +o Cowork of aufs and the user-space daemon + During the userspace daemon established the connection, aufs sends a + small notification to it whenever aufs writes something into the + writable branch. But it may cost high since aufs issues statfs(2) + internally. So user can specify a new option to cache the + info. Actually the notification is controlled by these factors. + + the specified cache time. + + classified as "force" by aufs internally. + Until the specified time expires, aufs doesn't send the info + except the forced cases. When aufs decide forcing, the info is always + notified to userspace. + For example, the number of free inodes is generally large enough and + the shortage of it happens rarely. So aufs doesn't force the + notification when creating a new file, directory and others. This is + the typical case which aufs doesn't force. + When aufs writes the actual filedata and the files consumes any of new + blocks, the aufs forces notifying. + + +o Interfaces in aufs +- New branch attribute. + + fhsm + Specifies that the branch is managed by FHSM feature.

In this case, + /sbin/mount.aufs will terminate the user-space daemon. + + +Finally the operation is done as these steps in kernel-space. +- make sure that, + + no one else is using the file. + + the file is not hard-linked. + + the file is not pseudo-linked. + + the file is a regular file. + + the parent dir is not opaqued. +- find the target writable branch. +- make sure the file is not whiteout-ed by the upper (than the target) + branch. +- make the parent dir on the target branch. +- mutex lock the inode on the branch. +- unlink the whiteout on the target branch (if exists). +- lookup and create the whiteout-ed temporary name on the target branch. +- copy the file as the whiteout-ed temporary name on the target branch. +- rename the whiteout-ed temporary name to the original name. +- unlink the file on the source branch. +- maintain the internal pointer array and the external inode number + table (XINO). +- maintain the timestamps and other attributes of the parent dir and the + file. + +And of course, in every step, an error may happen.

If not, see . + +mmap(2) -- File Memory Mapping +---------------------------------------------------------------------- +In aufs, the file-mapped pages are handled by a branch fs directly, no +interaction with aufs. It means aufs_mmap() calls the branch fs's +->mmap(). +This approach is simple and good, but there is one problem. +Under /proc, several entries show the mmapped files by its path (with +device and inode number), and the printed path will be the path on the +branch fs's instead of virtual aufs's. +This is not a problem in most cases, but some utilities lsof(1) (and its +user) may expect the path on aufs. + +To address this issue, aufs adds a new member called vm_prfile in struct +vm_area_struct (and struct vm_region). The original vm_file points to +the file on the branch fs in order to handle everything correctly as +usual. The new vm_prfile points to a virtual file in aufs, and the +show-functions in procfs refers to vm_prfile if it is set. +Also we need to maintain several other places where touching vm_file +such like +- fork()/clone() copies vma and the reference count of vm_file is + incremented. +- merging vma maintains the ref count too. + +This is not a good approach. It just fakes the printed path. But it +leaves all behaviour around f_mapping unchanged. This is surely an +advantage. +Actually aufs had adopted another complicated approach which calls +generic_file_mmap() and handles struct vm_operations_struct. In this +approach, aufs met a hard problem and I could not solve it without +switching the approach. + +There may be one more another approach which is +- bind-mount the branch-root onto the aufs-root internally +- grab the new vfsmount (ie. struct mount) +- lazy-umount the branch-root internally +- in open(2) the aufs-file, open the branch-file with the hidden + vfsmount (instead of the original branch's vfsmount) +- ideally this "bind-mount and lazy-umount" should be done atomically, + but it may be possible from userspace by the mount helper. + +Adding the internal hidden vfsmount and using it in opening a file, the +file path under /proc will be printed correctly. This approach looks +smarter, but is not possible I am afraid. +- aufs-root may be bind-mount later. when it happens, another hidden + vfsmount will be required. +- it is hard to get the chance to bind-mount and lazy-umount + + in kernel-space, FS can have vfsmount in open(2) via + file->f_path, and aufs can know its vfsmount. But several locks are + already acquired, and if aufs tries to bind-mount and lazy-umount + here, then it may cause a deadlock. + + in user-space, bind-mount doesn't invoke the mount helper. +- since /proc shows dev and ino, aufs has to give vma these info. it + means a new member vm_prinode will be necessary. this is essentially + equivalent to vm_prfile described above. + +I have to give up this "looks-smater" approach. --- linux-5.15.0.orig/Documentation/filesystems/aufs/design/06xattr.txt +++ linux-5.15.0/Documentation/filesystems/aufs/design/06xattr.txt @@ -0,0 +1,96 @@ + +# Copyright (C) 2014-2021 Junjiro R.

This behaviour is good +for the non-dir entries since the bahaviour exactly matches the shown +information. But for the directories, aufs considers all the same named +entries on the lower branches. Which means, if one of the lower entry +rejects readdir call, then aufs returns an error even if the topmost +entry allows it. This behaviour is necessary to respect the branch fs's +security, but can make users confused since the user-visible standard +attributes don't match the behaviour. +To address this issue, aufs has a mount option called dirperm1 which +checks the permission for the topmost entry only, and ignores the lower +entry's permission. + +A similar issue can happen around XATTR. +getxattr(2) and listxattr(2) families behave as if dirperm1 option is +always set. Otherwise these very unpleasant situation would happen. +- listxattr(2) may return the duplicated entries. +- users may not be able to remove or reset the XATTR forever, + + +XATTR/EA support in the internal (copy,move)-(up,down) +---------------------------------------------------------------------- +Generally the extended attributes of inode are categorized as these. +- "security" for LSM and capability. +- "system" for posix ACL, 'acl' mount option is required for the branch + fs generally. +- "trusted" for userspace, CAP_SYS_ADMIN is required. +- "user" for userspace, 'user_xattr' mount option is required for the + branch fs generally. + +Moreover there are some other categories. Aufs handles these rather +unpopular categories as the ordinary ones, ie. there is no special +condition nor exception. + +In copy-up, the support for XATTR on the dst branch may differ from the +src branch. In this case, the copy-up operation will get an error and +the original user operation which triggered the copy-up will fail. It +can happen that even all copy-up will fail. +When both of src and dst branches support XATTR and if an error occurs +during copying XATTR, then the copy-up should fail obviously. That is a +good reason and aufs should return an error to userspace. But when only +the src branch support that XATTR, aufs should not return an error. +For example, the src branch supports ACL but the dst branch doesn't +because the dst branch may natively un-support it or temporary +un-support it due to "noacl" mount option. Of course, the dst branch fs +may NOT return an error even if the XATTR is not supported. It is +totally up to the branch fs. + +Anyway when the aufs internal copy-up gets an error from the dst branch +fs, then aufs tries removing the just copied entry and returns the error +to the userspace. The worst case of this situation will be all copy-up +will fail. + +For the copy-up operation, there two basic approaches. +- copy the specified XATTR only (by category above), and return the + error unconditionally if it happens. +- copy all XATTR, and ignore the error on the specified category only. + +In order to support XATTR and to implement the correct behaviour, aufs +chooses the latter approach and introduces some new branch attributes, +"icexsec", "icexsys", "icextr", "icexusr", and "icexoth". +They correspond to the XATTR namespaces (see above). Additionally, to be +convenient, "icex" is also provided which means all "icex*" attributes +are set (here the word "icex" stands for "ignore copy-error on XATTR"). + +The meaning of these attributes is to ignore the error from setting +XATTR on that branch. +Note that aufs tries copying all XATTR unconditionally, and ignores the +error from the dst branch according to the specified attributes. + +Some XATTR may have its default value. The default value may come from +the parent dir or the environment. If the default value is set at the +file creating-time, it will be overwritten by copy-up. +Some contradiction may happen I am afraid. +Do we need another attribute to stop copying XATTR? I am unsure. For +now, aufs implements the branch attributes to ignore the error. --- linux-5.15.0.orig/Documentation/filesystems/aufs/design/07export.txt +++ linux-5.15.0/Documentation/filesystems/aufs/design/07export.txt @@ -0,0 +1,58 @@ + +# Copyright (C) 2005-2021 Junjiro R.

Some FS have multiple sets of them. For instance, ext2 has +three sets, one for XIP, for NOBH, and for normal. +Since aufs overrides and redirects these operations, sometimes aufs has +to change its behaviour according to the branch FS type. More importantly +VFS acts differently if a function (member in the struct) is set or +not. It means aufs should have several sets of operations and select one +among them according to the branch FS definition. + +In order to solve this problem and not to affect the behaviour of VFS, +aufs defines these operations dynamically. For instance, aufs defines +dummy direct_IO function for struct address_space_operations, but it may +not be set to the address_space_operations actually. When the branch FS +doesn't have it, aufs doesn't set it to its address_space_operations +while the function definition itself is still alive. So the behaviour +itself will not change, and it will return an error when direct_IO is +not set. + +The lifetime of these dynamically generated operation object is +maintained by aufs branch object. When the branch is removed from aufs, +the reference counter of the object is decremented. When it reaches +zero, the dynamically generated operation object will be freed. + +This approach is designed to support AIO (io_submit), Direct I/O and +XIP (DAX) mainly. +Currently this approach is applied to address_space_operations for +regular files only. --- linux-5.15.0.orig/Documentation/filesystems/autofs-mount-control.rst +++ linux-5.15.0/Documentation/filesystems/autofs-mount-control.rst @@ -196,7 +196,7 @@ struct args_ismountpoint ismountpoint; }; - char path[0]; + char path[]; }; The ioctlfd field is a mount point file descriptor of an autofs mount --- linux-5.15.0.orig/Documentation/filesystems/autofs.rst +++ linux-5.15.0/Documentation/filesystems/autofs.rst @@ -467,7 +467,7 @@ struct args_ismountpoint ismountpoint; }; - char path[0]; + char path[]; }; For the **OPEN_MOUNT** and **IS_MOUNTPOINT** commands, the target --- linux-5.15.0.orig/Documentation/filesystems/directory-locking.rst +++ linux-5.15.0/Documentation/filesystems/directory-locking.rst @@ -23,13 +23,15 @@ locks victim and calls the method.

Additionally +writing any value to CPR clears CPR2 for compatibility with old software +written for older conventional PCI Oxford Semiconductor devices that do +not have the extra prescaler's 9th bit in CPR2, so the CPR/CPR2 register +pair has to be programmed in the right order. + +By using these parameters rates from 15625000bps down to 1bps can be +obtained, with either exact or highly-accurate actual bit rates for +standard and many non-standard rates. + +Here are the figures for the standard and some non-standard baud rates +(including those quoted in Oxford Semiconductor documentation), giving +the requested rate (r), the actual rate yielded (a) and its deviation +from the requested rate (d), and the values of the oversampling rate +(tcr), the clock prescaler (cpr) and the divisor (div) produced by the +new `get_divisor' handler: + +r: 15625000, a: 15625000.00, d: 0.0000%, tcr: 4, cpr: 1.000, div: 1 +r: 12500000, a: 12500000.00, d: 0.0000%, tcr: 5, cpr: 1.000, div: 1 +r: 10416666, a: 10416666.67, d: 0.0000%, tcr: 6, cpr: 1.000, div: 1 +r: 8928571, a: 8928571.43, d: 0.0000%, tcr: 7, cpr: 1.000, div: 1 +r: 7812500, a: 7812500.00, d: 0.0000%, tcr: 8, cpr: 1.000, div: 1 +r: 4000000, a: 4000000.00, d: 0.0000%, tcr: 5, cpr: 3.125, div: 1 +r: 3686400, a: 3676470.59, d: -0.2694%, tcr: 8, cpr: 2.125, div: 1 +r: 3500000, a: 3496503.50, d: -0.0999%, tcr: 13, cpr: 1.375, div: 1 +r: 3000000, a: 2976190.48, d: -0.7937%, tcr: 14, cpr: 1.500, div: 1 +r: 2500000, a: 2500000.00, d: 0.0000%, tcr: 10, cpr: 2.500, div: 1 +r: 2000000, a: 2000000.00, d: 0.0000%, tcr: 10, cpr: 3.125, div: 1 +r: 1843200, a: 1838235.29, d: -0.2694%, tcr: 16, cpr: 2.125, div: 1 +r: 1500000, a: 1492537.31, d: -0.4975%, tcr: 5, cpr: 8.375, div: 1 +r: 1152000, a: 1152073.73, d: 0.0064%, tcr: 14, cpr: 3.875, div: 1 +r: 921600, a: 919117.65, d: -0.2694%, tcr: 16, cpr: 2.125, div: 2 +r: 576000, a: 576036.87, d: 0.0064%, tcr: 14, cpr: 3.875, div: 2 +r: 460800, a: 460829.49, d: 0.0064%, tcr: 7, cpr: 3.875, div: 5 +r: 230400, a: 230414.75, d: 0.0064%, tcr: 14, cpr: 3.875, div: 5 +r: 115200, a: 115207.37, d: 0.0064%, tcr: 14, cpr: 1.250, div: 31 +r: 57600, a: 57603.69, d: 0.0064%, tcr: 8, cpr: 3.875, div: 35 +r: 38400, a: 38402.46, d: 0.0064%, tcr: 14, cpr: 3.875, div: 30 +r: 19200, a: 19201.23, d: 0.0064%, tcr: 8, cpr: 3.875, div: 105 +r: 9600, a: 9600.06, d: 0.0006%, tcr: 9, cpr: 1.125, div: 643 +r: 4800, a: 4799.98, d: -0.0004%, tcr: 7, cpr: 2.875, div: 647 +r: 2400, a: 2400.02, d: 0.0008%, tcr: 9, cpr: 2.250, div: 1286 +r: 1200, a: 1200.00, d: 0.0000%, tcr: 14, cpr: 2.875, div: 1294 +r: 300, a: 300.00, d: 0.0000%, tcr: 11, cpr: 2.625, div: 7215 +r: 200, a: 200.00, d: 0.0000%, tcr: 16, cpr: 1.250, div: 15625 +r: 150, a: 150.00, d: 0.0000%, tcr: 13, cpr: 2.250, div: 14245 +r: 134, a: 134.00, d: 0.0000%, tcr: 11, cpr: 2.625, div: 16153 +r: 110, a: 110.00, d: 0.0000%, tcr: 12, cpr: 1.000, div: 47348 +r: 75, a: 75.00, d: 0.0000%, tcr: 4, cpr: 5.875, div: 35461 +r: 50, a: 50.00, d: 0.0000%, tcr: 16, cpr: 1.250, div: 62500 +r: 25, a: 25.00, d: 0.0000%, tcr: 16, cpr: 2.500, div: 62500 +r: 4, a: 4.00, d: 0.0000%, tcr: 16, cpr: 20.000, div: 48828 +r: 2, a: 2.00, d: 0.0000%, tcr: 16, cpr: 40.000, div: 48828 +r: 1, a: 1.00, d: 0.0000%, tcr: 16, cpr: 63.875, div: 61154 + +With the baud base set to 15625000 and the unsigned 16-bit UART_DIV_MAX +limitation imposed by `serial8250_get_baud_rate' standard baud rates +below 300bps become unavailable in the regular way, e.g. the rate of +200bps requires the baud base to be divided by 78125 and that is beyond +the unsigned 16-bit range.

Known KVM API problems +========================= + +In some cases, KVM's API has some inconsistencies or common pitfalls +that userspace need to be aware of.

SPDX-License-Identifier: GPL-2.0 + +========================================= +s390 (IBM Z) Ultravisor and Protected VMs +========================================= + +Summary +------- +Protected virtual machines (PVM) are KVM VMs that do not allow KVM to +access VM state like guest memory or guest registers. Instead, the +PVMs are mostly managed by a new entity called Ultravisor (UV). The UV +provides an API that can be used by PVMs and KVM to request management +actions. + +Each guest starts in non-protected mode and then may make a request to +transition into protected mode. On transition, KVM registers the guest +and its VCPUs with the Ultravisor and prepares everything for running +it. + +The Ultravisor will secure and decrypt the guest's boot memory +(i.e. kernel/initrd). It will safeguard state changes like VCPU +starts/stops and injected interrupts while the guest is running. + +As access to the guest's state, such as the SIE state description, is +normally needed to be able to run a VM, some changes have been made in +the behavior of the SIE instruction. A new format 4 state description +has been introduced, where some fields have different meanings for a +PVM. SIE exits are minimized as much as possible to improve speed and +reduce exposed guest state. + + +Interrupt injection +------------------- +Interrupt injection is safeguarded by the Ultravisor. As KVM doesn't +have access to the VCPUs' lowcores, injection is handled via the +format 4 state description. + +Machine check, external, IO and restart interruptions each can be +injected on SIE entry via a bit in the interrupt injection control +field (offset 0x54). If the guest cpu is not enabled for the interrupt +at the time of injection, a validity interception is recognized. The +format 4 state description contains fields in the interception data +block where data associated with the interrupt can be transported. + +Program and Service Call exceptions have another layer of +safeguarding; they can only be injected for instructions that have +been intercepted into KVM. The exceptions need to be a valid outcome +of an instruction emulation by KVM, e.g. we can never inject a +addressing exception as they are reported by SIE since KVM has no +access to the guest memory. + + +Mask notification interceptions +------------------------------- +KVM cannot intercept lctl(g) and lpsw(e) anymore in order to be +notified when a PVM enables a certain class of interrupt. As a +replacement, two new interception codes have been introduced: One +indicating that the contents of CRs 0, 6, or 14 have been changed, +indicating different interruption subclasses; and one indicating that +PSW bit 13 has been changed, indicating that a machine check +intervention was requested and those are now enabled. + +Instruction emulation +--------------------- +With the format 4 state description for PVMs, the SIE instruction already +interprets more instructions than it does with format 2. It is not able +to interpret every instruction, but needs to hand some tasks to KVM; +therefore, the SIE and the ultravisor safeguard emulation inputs and outputs. + +The control structures associated with SIE provide the Secure +Instruction Data Area (SIDA), the Interception Parameters (IP) and the +Secure Interception General Register Save Area. Guest GRs and most of +the instruction data, such as I/O data structures, are filtered. +Instruction data is copied to and from the SIDA when needed. Guest +GRs are put into / retrieved from the Secure Interception General +Register Save Area. + +Only GR values needed to emulate an instruction will be copied into this +save area and the real register numbers will be hidden. + +The Interception Parameters state description field still contains +the bytes of the instruction text, but with pre-set register values +instead of the actual ones. I.e. each instruction always uses the same +instruction text, in order not to leak guest instruction text. +This also implies that the register content that a guest had in r +may be in r from the hypervisor's point of view. + +The Secure Instruction Data Area contains instruction storage +data. Instruction data, i.e. data being referenced by an instruction +like the SCCB for sclp, is moved via the SIDA. When an instruction is +intercepted, the SIE will only allow data and program interrupts for +this instruction to be moved to the guest via the two data areas +discussed before. Other data is either ignored or results in validity +interceptions. + + +Instruction emulation interceptions +----------------------------------- +There are two types of SIE secure instruction intercepts: the normal +and the notification type. Normal secure instruction intercepts will +make the guest pending for instruction completion of the intercepted +instruction type, i.e. on SIE entry it is attempted to complete +emulation of the instruction with the data provided by KVM. That might +be a program exception or instruction completion. + +The notification type intercepts inform KVM about guest environment +changes due to guest instruction interpretation. Such an interception +is recognized, for example, for the store prefix instruction to provide +the new lowcore location. On SIE reentry, any KVM data in the data areas +is ignored and execution continues as if the guest instruction had +completed. For that reason KVM is not allowed to inject a program +interrupt. + +Links +----- +`KVM Forum 2019 presentation `_ --- linux-5.15.0.orig/Documentation/virt/kvm/x86/amd-memory-encryption.rst +++ linux-5.15.0/Documentation/virt/kvm/x86/amd-memory-encryption.rst @@ -0,0 +1,439 @@ +====================================== +Secure Encrypted Virtualization (SEV) +====================================== + +Overview +======== + +Secure Encrypted Virtualization (SEV) is a feature found on AMD processors. + +SEV is an extension to the AMD-V architecture which supports running +virtual machines (VMs) under the control of a hypervisor.

If the argument +to KVM_MEMORY_ENCRYPT_OP is NULL, the ioctl returns 0 if SEV is enabled +and ``ENOTTY` if it is disabled (on some older versions of Linux, +the ioctl runs normally even with a NULL argument, and therefore will +likely return ``EFAULT``).

Error codes +are defined in ````. + +KVM implements the following commands to support common lifecycle events of SEV +guests, such as launching, running, snapshotting, migrating and decommissioning. + +1.

SPDX-License-Identifier: GPL-2.0 + +=========================== +The KVM halt polling system +=========================== + +The KVM halt polling system provides a feature within KVM whereby the latency +of a guest can, under some circumstances, be reduced by polling in the host +for some time period after the guest has elected to no longer run by cedeing. +That is, when a guest vcpu has ceded, or in the case of powerpc when all of the +vcpus of a single vcore have ceded, the host kernel polls for wakeup conditions +before giving up the cpu to the scheduler in order to let something else run. + +Polling provides a latency advantage in cases where the guest can be run again +very quickly by at least saving us a trip through the scheduler, normally on +the order of a few micro-seconds, although performance benefits are workload +dependant. In the event that no wakeup source arrives during the polling +interval or some other task on the runqueue is runnable the scheduler is +invoked. Thus halt polling is especially useful on workloads with very short +wakeup periods where the time spent halt polling is minimised and the time +savings of not invoking the scheduler are distinguishable. + +The generic halt polling code is implemented in: + + virt/kvm/kvm_main.c: kvm_vcpu_block() + +The powerpc kvm-hv specific case is implemented in: + + arch/powerpc/kvm/book3s_hv.c: kvmppc_vcore_blocked() + +Halt Polling Interval +===================== + +The maximum time for which to poll before invoking the scheduler, referred to +as the halt polling interval, is increased and decreased based on the perceived +effectiveness of the polling in an attempt to limit pointless polling. +This value is stored in either the vcpu struct: + + kvm_vcpu->halt_poll_ns + +or in the case of powerpc kvm-hv, in the vcore struct: + + kvmppc_vcore->halt_poll_ns + +Thus this is a per vcpu (or vcore) value. + +During polling if a wakeup source is received within the halt polling interval, +the interval is left unchanged. In the event that a wakeup source isn't +received during the polling interval (and thus schedule is invoked) there are +two options, either the polling interval and total block time[0] were less than +the global max polling interval (see module params below), or the total block +time was greater than the global max polling interval. + +In the event that both the polling interval and total block time were less than +the global max polling interval then the polling interval can be increased in +the hope that next time during the longer polling interval the wake up source +will be received while the host is polling and the latency benefits will be +received. The polling interval is grown in the function grow_halt_poll_ns() and +is multiplied by the module parameters halt_poll_ns_grow and +halt_poll_ns_grow_start. + +In the event that the total block time was greater than the global max polling +interval then the host will never poll for long enough (limited by the global +max) to wakeup during the polling interval so it may as well be shrunk in order +to avoid pointless polling. The polling interval is shrunk in the function +shrink_halt_poll_ns() and is divided by the module parameter +halt_poll_ns_shrink, or set to 0 iff halt_poll_ns_shrink == 0. + +It is worth noting that this adjustment process attempts to hone in on some +steady state polling interval but will only really do a good job for wakeups +which come at an approximately constant rate, otherwise there will be constant +adjustment of the polling interval. + +[0] total block time: + the time between when the halt polling function is + invoked and a wakeup source received (irrespective of + whether the scheduler is invoked within that function). + +Module Parameters +================= + +The kvm module has 3 tuneable module parameters to adjust the global max +polling interval as well as the rate at which the polling interval is grown and +shrunk.

These are always the lowest level of the +translation stack, with optional higher level translations left to NPT/EPT. +Leaf ptes point at guest pages. + +The following table shows translations encoded by leaf ptes, with higher-level +translations in parentheses: + + Non-nested guests:: + + nonpaging: gpa->hpa + paging: gva->gpa->hpa + paging, tdp: (gva->)gpa->hpa + + Nested guests:: + + non-tdp: ngva->gpa->hpa (*) + tdp: (ngva->)ngpa->gpa->hpa + + (*) the guest hypervisor will encode the ngva->gpa translation into its page + tables if npt is not present + +Shadow pages contain the following information: + role.level: + The level in the shadow paging hierarchy that this shadow page belongs to. + 1=4k sptes, 2=2M sptes, 3=1G sptes, etc. + role.direct: + If set, leaf sptes reachable from this page are for a linear range. + Examples include real mode translation, large guest pages backed by small + host pages, and gpa->hpa translations when NPT or EPT is active. + The linear range starts at (gfn << PAGE_SHIFT) and its size is determined + by role.level (2MB for first level, 1GB for second level, 0.5TB for third + level, 256TB for fourth level) + If clear, this page corresponds to a guest page table denoted by the gfn + field. + role.quadrant: + When role.gpte_is_8_bytes=0, the guest uses 32-bit gptes while the host uses 64-bit + sptes. That means a guest page table contains more ptes than the host, + so multiple shadow pages are needed to shadow one guest page. + For first-level shadow pages, role.quadrant can be 0 or 1 and denotes the + first or second 512-gpte block in the guest page table. For second-level + page tables, each 32-bit gpte is converted to two 64-bit sptes + (since each first-level guest page is shadowed by two first-level + shadow pages) so role.quadrant takes values in the range 0..3. Each + quadrant maps 1GB virtual address space. + role.access: + Inherited guest access permissions from the parent ptes in the form uwx. + Note execute permission is positive, not negative. + role.invalid: + The page is invalid and should not be used. It is a root page that is + currently pinned (by a cpu hardware register pointing to it); once it is + unpinned it will be destroyed. + role.gpte_is_8_bytes: + Reflects the size of the guest PTE for which the page is valid, i.e. '1' + if 64-bit gptes are in use, '0' if 32-bit gptes are in use. + role.efer_nx: + Contains the value of efer.nx for which the page is valid. + role.cr0_wp: + Contains the value of cr0.wp for which the page is valid. + role.smep_andnot_wp: + Contains the value of cr4.smep && !cr0.wp for which the page is valid + (pages for which this is true are different from other pages; see the + treatment of cr0.wp=0 below). + role.smap_andnot_wp: + Contains the value of cr4.smap && !cr0.wp for which the page is valid + (pages for which this is true are different from other pages; see the + treatment of cr0.wp=0 below). + role.smm: + Is 1 if the page is valid in system management mode. This field + determines which of the kvm_memslots array was used to build this + shadow page; it is also used to go back from a struct kvm_mmu_page + to a memslot, through the kvm_memslots_for_spte_role macro and + __gfn_to_memslot. + role.ad_disabled: + Is 1 if the MMU instance cannot use A/D bits. EPT did not have A/D + bits before Haswell; shadow EPT page tables also cannot use A/D bits + if the L1 hypervisor does not enable them. + gfn: + Either the guest page table containing the translations shadowed by this + page, or the base page frame for linear translations. See role.direct. + spt: + A pageful of 64-bit sptes containing the translations for this page. + Accessed by both kvm and hardware. + The page pointed to by spt will have its page->private pointing back + at the shadow page structure. + sptes in spt point either at guest pages, or at lower-level shadow pages. + Specifically, if sp1 and sp2 are shadow pages, then sp1->spt[n] may point + at __pa(sp2->spt). sp2 will point back at sp1 through parent_pte. + The spt array forms a DAG structure with the shadow page as a node, and + guest pages as leaves. + gfns: + An array of 512 guest frame numbers, one for each present pte. Used to + perform a reverse map from a pte to a gfn. When role.direct is set, any + element of this array can be calculated from the gfn field when used, in + this case, the array of gfns is not allocated. See role.direct and gfn. + root_count: + A counter keeping track of how many hardware registers (guest cr3 or + pdptrs) are now pointing at the page. While this counter is nonzero, the + page cannot be destroyed. See role.invalid. + parent_ptes: + The reverse mapping for the pte/ptes pointing at this page's spt. If + parent_ptes bit 0 is zero, only one spte points at this page and + parent_ptes points at this single spte, otherwise, there exists multiple + sptes pointing at this page and (parent_ptes & ~0x1) points at a data + structure with a list of parent sptes. + unsync: + If true, then the translations in this page may not match the guest's + translation. This is equivalent to the state of the tlb when a pte is + changed but before the tlb entry is flushed. Accordingly, unsync ptes + are synchronized when the guest executes invlpg or flushes its tlb by + other means. Valid for leaf pages. + unsync_children: + How many sptes in the page point at pages that are unsync (or have + unsynchronized children). + unsync_child_bitmap: + A bitmap indicating which sptes in spt point (directly or indirectly) at + pages that may be unsynchronized. Used to quickly locate all unsychronized + pages reachable from a given page. + clear_spte_count: + Only present on 32-bit hosts, where a 64-bit spte cannot be written + atomically. The reader uses this while running out of the MMU lock + to detect in-progress updates and retry them until the writer has + finished the write. + write_flooding_count: + A guest may write to a page table many times, causing a lot of + emulations if the page needs to be write-protected (see "Synchronized + and unsynchronized pages" below). Leaf pages can be unsynchronized + so that they do not trigger frequent emulation, but this is not + possible for non-leafs. This field counts the number of emulations + since the last time the page table was actually used; if emulation + is triggered too frequently on this page, KVM will unmap the page + to avoid emulation in the future. + +Reverse map +=========== + +The mmu maintains a reverse mapping whereby all ptes mapping a page can be +reached given its gfn. This is used, for example, when swapping out a page. + +Synchronized and unsynchronized pages +===================================== + +The guest uses two events to synchronize its tlb and page tables: tlb flushes +and page invalidations (invlpg). + +A tlb flush means that we need to synchronize all sptes reachable from the +guest's cr3. This is expensive, so we keep all guest page tables write +protected, and synchronize sptes to gptes when a gpte is written. + +A special case is when a guest page table is reachable from the current +guest cr3. In this case, the guest is obliged to issue an invlpg instruction +before using the translation. We take advantage of that by removing write +protection from the guest page, and allowing the guest to modify it freely. +We synchronize modified gptes when the guest invokes invlpg. This reduces +the amount of emulation we have to do when the guest modifies multiple gptes, +or when the a guest page is no longer used as a page table and is used for +random guest data. + +As a side effect we have to resynchronize all reachable unsynchronized shadow +pages on a tlb flush. + + +Reaction to events +================== + +- guest page fault (or npt page fault, or ept violation) + +This is the most complicated event. The cause of a page fault can be: + + - a true guest fault (the guest translation won't allow the access) (*) + - access to a missing translation + - access to a protected translation + - when logging dirty pages, memory is write protected + - synchronized shadow pages are write protected (*) + - access to untranslatable memory (mmio) + + (*) not applicable in direct mode + +Handling a page fault is performed as follows: + + - if the RSV bit of the error code is set, the page fault is caused by guest + accessing MMIO and cached MMIO information is available. + + - walk shadow page table + - check for valid generation number in the spte (see "Fast invalidation of + MMIO sptes" below) + - cache the information to vcpu->arch.mmio_gva, vcpu->arch.mmio_access and + vcpu->arch.mmio_gfn, and call the emulator + + - If both P bit and R/W bit of error code are set, this could possibly + be handled as a "fast page fault" (fixed without taking the MMU lock). See + the description in Documentation/virt/kvm/locking.rst. + + - if needed, walk the guest page tables to determine the guest translation + (gva->gpa or ngpa->gpa) + + - if permissions are insufficient, reflect the fault back to the guest + + - determine the host page + + - if this is an mmio request, there is no host page; cache the info to + vcpu->arch.mmio_gva, vcpu->arch.mmio_access and vcpu->arch.mmio_gfn + + - walk the shadow page table to find the spte for the translation, + instantiating missing intermediate page tables as necessary + + - If this is an mmio request, cache the mmio info to the spte and set some + reserved bit on the spte (see callers of kvm_mmu_set_mmio_spte_mask) + + - try to unsynchronize the page + + - if successful, we can let the guest continue and modify the gpte + + - emulate the instruction + + - if failed, unshadow the page and let the guest continue + + - update any translations that were modified by the instruction + +invlpg handling: + + - walk the shadow page hierarchy and drop affected translations + - try to reinstantiate the indicated translation in the hope that the + guest will use it in the near future + +Guest control register updates: + +- mov to cr3 + + - look up new shadow roots + - synchronize newly reachable shadow pages + +- mov to cr0/cr4/efer + + - set up mmu context for new paging mode + - look up new shadow roots + - synchronize newly reachable shadow pages + +Host translation updates: + + - mmu notifier called with updated hva + - look up affected sptes through reverse map + - drop (or update) translations + +Emulating cr0.wp +================ + +If tdp is not enabled, the host must keep cr0.wp=1 so page write protection +works for the guest kernel, not guest guest userspace. When the guest +cr0.wp=1, this does not present a problem. However when the guest cr0.wp=0, +we cannot map the permissions for gpte.u=1, gpte.w=0 to any spte (the +semantics require allowing any guest kernel access plus user read access). + +We handle this by mapping the permissions to two possible sptes, depending +on fault type: + +- kernel write fault: spte.u=0, spte.w=1 (allows full kernel access, + disallows user access) +- read fault: spte.u=1, spte.w=0 (allows full read access, disallows kernel + write access) + +(user write faults generate a #PF) + +In the first case there are two additional complications: + +- if CR4.SMEP is enabled: since we've turned the page into a kernel page, + the kernel may now execute it. We handle this by also setting spte.nx. + If we get a user fetch or read fault, we'll change spte.u=1 and + spte.nx=gpte.nx back. For this to work, KVM forces EFER.NX to 1 when + shadow paging is in use. +- if CR4.SMAP is disabled: since the page has been changed to a kernel + page, it can not be reused when CR4.SMAP is enabled. We set + CR4.SMAP && !CR0.WP into shadow page's role to avoid this case. Note, + here we do not care the case that CR4.SMAP is enabled since KVM will + directly inject #PF to guest due to failed permission check. + +To prevent an spte that was converted into a kernel page with cr0.wp=0 +from being written by the kernel after cr0.wp has changed to 1, we make +the value of cr0.wp part of the page role. This means that an spte created +with one value of cr0.wp cannot be used when cr0.wp has a different value - +it will simply be missed by the shadow page lookup code. A similar issue +exists when an spte created with cr0.wp=0 and cr4.smep=0 is used after +changing cr4.smep to 1. To avoid this, the value of !cr0.wp && cr4.smep +is also made a part of the page role. + +Large pages +=========== + +The mmu supports all combinations of large and small guest and host pages. +Supported page sizes include 4k, 2M, 4M, and 1G. 4M pages are treated as +two separate 2M pages, on both guest and host, since the mmu always uses PAE +paging. + +To instantiate a large spte, four constraints must be satisfied: + +- the spte must point to a large host page +- the guest pte must be a large pte of at least equivalent size (if tdp is + enabled, there is no guest pte and this condition is satisfied) +- if the spte will be writeable, the large page frame may not overlap any + write-protected pages +- the guest page must be wholly contained by a single memory slot + +To check the last two conditions, the mmu maintains a ->disallow_lpage set of +arrays for each memory slot and large page size. Every write protected page +causes its disallow_lpage to be incremented, thus preventing instantiation of +a large spte. The frames at the end of an unaligned memory slot have +artificially inflated ->disallow_lpages so they can never be instantiated. + +Fast invalidation of MMIO sptes +=============================== + +As mentioned in "Reaction to events" above, kvm will cache MMIO +information in leaf sptes. When a new memslot is added or an existing +memslot is changed, this information may become stale and needs to be +invalidated. This also needs to hold the MMU lock while walking all +shadow pages, and is made more scalable with a similar technique. + +MMIO sptes have a few spare bits, which are used to store a +generation number. The global generation number is stored in +kvm_memslots(kvm)->generation, and increased whenever guest memory info +changes. + +When KVM finds an MMIO spte, it checks the generation number of the spte. +If the generation number of the spte does not equal the global generation +number, it will ignore the cached MMIO information and handle the page +fault through the slow path. + +Since only 18 bits are used to store generation-number on mmio spte, all +pages are zapped when there is an overflow. + +Unfortunately, a single memory access might access kvm_memslots(kvm) multiple +times, the last one happening when the generation number is retrieved and +stored into the MMIO spte. Thus, the MMIO spte might be created based on +out-of-date information, but with an up-to-date generation number. + +To avoid this, the generation number is incremented again after synchronize_srcu +returns; thus, bit 63 of kvm_memslots(kvm)->generation set to 1 only during a +memslot update, while some SRCU readers might be using the old copy. We do not +want to use an MMIO sptes created with an odd generation number, and we can do +this without losing a bit in the MMIO spte. The "update in-progress" bit of the +generation is not stored in MMIO spte, and is so is implicitly zero when the +generation is extracted out of the spte. If KVM is unlucky and creates an MMIO +spte while an update is in-progress, the next access to the spte will always be +a cache miss. For example, a subsequent access during the update window will +miss due to the in-progress flag diverging, while an access after the update +window closes will have a higher generation number (as compared to the spte). + + +Further reading +=============== + +- NPT presentation from KVM Forum 2008 + https://www.linux-kvm.org/images/c/c8/KvmForum2008%24kdf2008_21.pdf --- linux-5.15.0.orig/Documentation/virt/kvm/x86/msr.rst +++ linux-5.15.0/Documentation/virt/kvm/x86/msr.rst @@ -0,0 +1,391 @@ +..

SPDX-License-Identifier: GPL-2.0 + +========== +Nested VMX +========== + +Overview +--------- + +On Intel processors, KVM uses Intel's VMX (Virtual-Machine eXtensions) +to easily and efficiently run guest operating systems. Normally, these guests +*cannot* themselves be hypervisors running their own guests, because in VMX, +guests cannot use VMX instructions. + +The "Nested VMX" feature adds this missing capability - of running guest +hypervisors (which use VMX) with their own nested guests. It does so by +allowing a guest to use VMX instructions, and correctly and efficiently +emulating them using the single level of VMX available in the hardware. + +We describe in much greater detail the theory behind the nested VMX feature, +its implementation and its performance characteristics, in the OSDI 2010 paper +"The Turtles Project: Design and Implementation of Nested Virtualization", +available at: + + https://www.usenix.org/events/osdi10/tech/full_papers/Ben-Yehuda.pdf + + +Terminology +----------- + +Single-level virtualization has two levels - the host (KVM) and the guests. +In nested virtualization, we have three levels: The host (KVM), which we call +L0, the guest hypervisor, which we call L1, and its nested guest, which we +call L2. + + +Running nested VMX +------------------ + +The nested VMX feature is enabled by default since Linux kernel v4.20. For +older Linux kernel, it can be enabled by giving the "nested=1" option to the +kvm-intel module. + + +No modifications are required to user space (qemu). However, qemu's default +emulated CPU type (qemu64) does not list the "VMX" CPU feature, so it must be +explicitly enabled, by giving qemu one of the following options: + + - cpu host (emulated CPU has all features of the real CPU) + + - cpu qemu64,+vmx (add just the vmx feature to a named CPU type) + + +ABIs +---- + +Nested VMX aims to present a standard and (eventually) fully-functional VMX +implementation for the a guest hypervisor to use. As such, the official +specification of the ABI that it provides is Intel's VMX specification, +namely volume 3B of their "Intel 64 and IA-32 Architectures Software +Developer's Manual". Not all of VMX's features are currently fully supported, +but the goal is to eventually support them all, starting with the VMX features +which are used in practice by popular hypervisors (KVM and others). + +As a VMX implementation, nested VMX presents a VMCS structure to L1. +As mandated by the spec, other than the two fields revision_id and abort, +this structure is *opaque* to its user, who is not supposed to know or care +about its internal structure. Rather, the structure is accessed through the +VMREAD and VMWRITE instructions. +Still, for debugging purposes, KVM developers might be interested to know the +internals of this structure; This is struct vmcs12 from arch/x86/kvm/vmx.c. + +The name "vmcs12" refers to the VMCS that L1 builds for L2. In the code we +also have "vmcs01", the VMCS that L0 built for L1, and "vmcs02" is the VMCS +which L0 builds to actually run L2 - how this is done is explained in the +aforementioned paper. + +For convenience, we repeat the content of struct vmcs12 here.

In addition, virtualization of +time introduces a new set of challenges because it introduces a multiplexed +division of time beyond the control of the guest CPU. + +First, we will describe the various timekeeping hardware available, then +present some of the problems which arise and solutions available, giving +specific recommendations for certain classes of KVM guests. + +The purpose of this document is to collect data and information relevant to +timekeeping which may be difficult to find elsewhere, specifically, +information relevant to KVM and hardware-based virtualization. + +2. Timing Devices +================= + +First we discuss the basic hardware devices available. TSC and the related +KVM clock are special enough to warrant a full exposition and are described in +the following section. + +2.1. i8254 - PIT +---------------- + +One of the first timer devices available is the programmable interrupt timer, +or PIT. The PIT has a fixed frequency 1.193182 MHz base clock and three +channels which can be programmed to deliver periodic or one-shot interrupts. +These three channels can be configured in different modes and have individual +counters. Channel 1 and 2 were not available for general use in the original +IBM PC, and historically were connected to control RAM refresh and the PC +speaker. Now the PIT is typically integrated as part of an emulated chipset +and a separate physical PIT is not used. + +The PIT uses I/O ports 0x40 - 0x43. Access to the 16-bit counters is done +using single or multiple byte access to the I/O ports. There are 6 modes +available, but not all modes are available to all timers, as only timer 2 +has a connected gate input, required for modes 1 and 5. The gate line is +controlled by port 61h, bit 0, as illustrated in the following diagram:: + + -------------- ---------------- + | | | | + | 1.1932 MHz|---------->| CLOCK OUT | ---------> IRQ 0 + | Clock | | | | + -------------- | +->| GATE TIMER 0 | + | ---------------- + | + | ---------------- + | | | + |------>| CLOCK OUT | ---------> 66.3 KHZ DRAM + | | | (aka /dev/null) + | +->| GATE TIMER 1 | + | ---------------- + | + | ---------------- + | | | + |------>| CLOCK OUT | ---------> Port 61h, bit 5 + | | | + Port 61h, bit 0 -------->| GATE TIMER 2 | \_.---- ____ + ---------------- _| )--|LPF|---Speaker + / *---- \___/ + Port 61h, bit 1 ---------------------------------/ + +The timer modes are now described. + +Mode 0: Single Timeout. + This is a one-shot software timeout that counts down + when the gate is high (always true for timers 0 and 1). When the count + reaches zero, the output goes high. + +Mode 1: Triggered One-shot. + The output is initially set high. When the gate + line is set high, a countdown is initiated (which does not stop if the gate is + lowered), during which the output is set low. When the count reaches zero, + the output goes high. + +Mode 2: Rate Generator. + The output is initially set high. When the countdown + reaches 1, the output goes low for one count and then returns high. The value + is reloaded and the countdown automatically resumes. If the gate line goes + low, the count is halted. If the output is low when the gate is lowered, the + output automatically goes high (this only affects timer 2). + +Mode 3: Square Wave. + This generates a high / low square wave. The count + determines the length of the pulse, which alternates between high and low + when zero is reached. The count only proceeds when gate is high and is + automatically reloaded on reaching zero. The count is decremented twice at + each clock to generate a full high / low cycle at the full periodic rate. + If the count is even, the clock remains high for N/2 counts and low for N/2 + counts; if the clock is odd, the clock is high for (N+1)/2 counts and low + for (N-1)/2 counts. Only even values are latched by the counter, so odd + values are not observed when reading. This is the intended mode for timer 2, + which generates sine-like tones by low-pass filtering the square wave output. + +Mode 4: Software Strobe. + After programming this mode and loading the counter, + the output remains high until the counter reaches zero. Then the output + goes low for 1 clock cycle and returns high. The counter is not reloaded. + Counting only occurs when gate is high. + +Mode 5: Hardware Strobe. + After programming and loading the counter, the + output remains high. When the gate is raised, a countdown is initiated + (which does not stop if the gate is lowered). When the counter reaches zero, + the output goes low for 1 clock cycle and then returns high. The counter is + not reloaded. + +In addition to normal binary counting, the PIT supports BCD counting. The +command port, 0x43 is used to set the counter and mode for each of the three +timers. + +PIT commands, issued to port 0x43, using the following bit encoding:: + + Bit 7-4: Command (See table below) + Bit 3-1: Mode (000 = Mode 0, 101 = Mode 5, 11X = undefined) + Bit 0 : Binary (0) / BCD (1) + +Command table:: + + 0000 - Latch Timer 0 count for port 0x40 + sample and hold the count to be read in port 0x40; + additional commands ignored until counter is read; + mode bits ignored. + + 0001 - Set Timer 0 LSB mode for port 0x40 + set timer to read LSB only and force MSB to zero; + mode bits set timer mode + + 0010 - Set Timer 0 MSB mode for port 0x40 + set timer to read MSB only and force LSB to zero; + mode bits set timer mode + + 0011 - Set Timer 0 16-bit mode for port 0x40 + set timer to read / write LSB first, then MSB; + mode bits set timer mode + + 0100 - Latch Timer 1 count for port 0x41 - as described above + 0101 - Set Timer 1 LSB mode for port 0x41 - as described above + 0110 - Set Timer 1 MSB mode for port 0x41 - as described above + 0111 - Set Timer 1 16-bit mode for port 0x41 - as described above + + 1000 - Latch Timer 2 count for port 0x42 - as described above + 1001 - Set Timer 2 LSB mode for port 0x42 - as described above + 1010 - Set Timer 2 MSB mode for port 0x42 - as described above + 1011 - Set Timer 2 16-bit mode for port 0x42 as described above + + 1101 - General counter latch + Latch combination of counters into corresponding ports + Bit 3 = Counter 2 + Bit 2 = Counter 1 + Bit 1 = Counter 0 + Bit 0 = Unused + + 1110 - Latch timer status + Latch combination of counter mode into corresponding ports + Bit 3 = Counter 2 + Bit 2 = Counter 1 + Bit 1 = Counter 0 + + The output of ports 0x40-0x42 following this command will be: + + Bit 7 = Output pin + Bit 6 = Count loaded (0 if timer has expired) + Bit 5-4 = Read / Write mode + 01 = MSB only + 10 = LSB only + 11 = LSB / MSB (16-bit) + Bit 3-1 = Mode + Bit 0 = Binary (0) / BCD mode (1) + +2.2. RTC +-------- + +The second device which was available in the original PC was the MC146818 real +time clock. The original device is now obsolete, and usually emulated by the +system chipset, sometimes by an HPET and some frankenstein IRQ routing. + +The RTC is accessed through CMOS variables, which uses an index register to +control which bytes are read. Since there is only one index register, read +of the CMOS and read of the RTC require lock protection (in addition, it is +dangerous to allow userspace utilities such as hwclock to have direct RTC +access, as they could corrupt kernel reads and writes of CMOS memory). + +The RTC generates an interrupt which is usually routed to IRQ 8.

APIC +--------- + +On Pentium and later processors, an on-board timer is available to each CPU +as part of the Advanced Programmable Interrupt Controller. The APIC is +accessed through memory-mapped registers and provides interrupt service to each +CPU, used for IPIs and local timer interrupts. + +Although in theory the APIC is a safe and stable source for local interrupts, +in practice, many bugs and glitches have occurred due to the special nature of +the APIC CPU-local memory-mapped hardware. Beware that CPU errata may affect +the use of the APIC and that workarounds may be required. In addition, some of +these workarounds pose unique constraints for virtualization - requiring either +extra overhead incurred from extra reads of memory-mapped I/O or additional +functionality that may be more computationally expensive to implement. + +Since the APIC is documented quite well in the Intel and AMD manuals, we will +avoid repetition of the detail here. It should be pointed out that the APIC +timer is programmed through the LVT (local vector timer) register, is capable +of one-shot or periodic operation, and is based on the bus clock divided down +by the programmable divider register. + +2.4. HPET +--------- + +HPET is quite complex, and was originally intended to replace the PIT / RTC +support of the X86 PC. It remains to be seen whether that will be the case, as +the de facto standard of PC hardware is to emulate these older devices. Some +systems designated as legacy free may support only the HPET as a hardware timer +device. + +The HPET spec is rather loose and vague, requiring at least 3 hardware timers, +but allowing implementation freedom to support many more. It also imposes no +fixed rate on the timer frequency, but does impose some extremal values on +frequency, error and slew. + +In general, the HPET is recommended as a high precision (compared to PIT /RTC) +time source which is independent of local variation (as there is only one HPET +in any given system). The HPET is also memory-mapped, and its presence is +indicated through ACPI tables by the BIOS. + +Detailed specification of the HPET is beyond the current scope of this +document, as it is also very well documented elsewhere. + +2.5. Offboard Timers +-------------------- + +Several cards, both proprietary (watchdog boards) and commonplace (e1000) have +timing chips built into the cards which may have registers which are accessible +to kernel or user drivers. To the author's knowledge, using these to generate +a clocksource for a Linux or other kernel has not yet been attempted and is in +general frowned upon as not playing by the agreed rules of the game. Such a +timer device would require additional support to be virtualized properly and is +not considered important at this time as no known operating system does this. + +3. TSC Hardware +=============== + +The TSC or time stamp counter is relatively simple in theory; it counts +instruction cycles issued by the processor, which can be used as a measure of +time. In practice, due to a number of problems, it is the most complicated +timekeeping device to use. + +The TSC is represented internally as a 64-bit MSR which can be read with the +RDMSR, RDTSC, or RDTSCP (when available) instructions. In the past, hardware +limitations made it possible to write the TSC, but generally on old hardware it +was only possible to write the low 32-bits of the 64-bit counter, and the upper +32-bits of the counter were cleared. Now, however, on Intel processors family +0Fh, for models 3, 4 and 6, and family 06h, models e and f, this restriction +has been lifted and all 64-bits are writable. On AMD systems, the ability to +write the TSC MSR is not an architectural guarantee. + +The TSC is accessible from CPL-0 and conditionally, for CPL > 0 software by +means of the CR4.TSD bit, which when enabled, disables CPL > 0 TSC access. + +Some vendors have implemented an additional instruction, RDTSCP, which returns +atomically not just the TSC, but an indicator which corresponds to the +processor number. This can be used to index into an array of TSC variables to +determine offset information in SMP systems where TSCs are not synchronized. +The presence of this instruction must be determined by consulting CPUID feature +bits. + +Both VMX and SVM provide extension fields in the virtualization hardware which +allows the guest visible TSC to be offset by a constant. Newer implementations +promise to allow the TSC to additionally be scaled, but this hardware is not +yet widely available. + +3.1. TSC synchronization +------------------------ + +The TSC is a CPU-local clock in most implementations. This means, on SMP +platforms, the TSCs of different CPUs may start at different times depending +on when the CPUs are powered on. Generally, CPUs on the same die will share +the same clock, however, this is not always the case. + +The BIOS may attempt to resynchronize the TSCs during the poweron process and +the operating system or other system software may attempt to do this as well. +Several hardware limitations make the problem worse - if it is not possible to +write the full 64-bits of the TSC, it may be impossible to match the TSC in +newly arriving CPUs to that of the rest of the system, resulting in +unsynchronized TSCs. This may be done by BIOS or system software, but in +practice, getting a perfectly synchronized TSC will not be possible unless all +values are read from the same clock, which generally only is possible on single +socket systems or those with special hardware support. + +3.2. TSC and CPU hotplug +------------------------ + +As touched on already, CPUs which arrive later than the boot time of the system +may not have a TSC value that is synchronized with the rest of the system. +Either system software, BIOS, or SMM code may actually try to establish the TSC +to a value matching the rest of the system, but a perfect match is usually not +a guarantee. This can have the effect of bringing a system from a state where +TSC is synchronized back to a state where TSC synchronization flaws, however +small, may be exposed to the OS and any virtualization environment. + +3.3. TSC and multi-socket / NUMA +-------------------------------- + +Multi-socket systems, especially large multi-socket systems are likely to have +individual clocksources rather than a single, universally distributed clock. +Since these clocks are driven by different crystals, they will not have +perfectly matched frequency, and temperature and electrical variations will +cause the CPU clocks, and thus the TSCs to drift over time. Depending on the +exact clock and bus design, the drift may or may not be fixed in absolute +error, and may accumulate over time. + +In addition, very large systems may deliberately slew the clocks of individual +cores. This technique, known as spread-spectrum clocking, reduces EMI at the +clock frequency and harmonics of it, which may be required to pass FCC +standards for telecommunications and computer equipment. + +It is recommended not to trust the TSCs to remain synchronized on NUMA or +multiple socket systems for these reasons. + +3.4. TSC and C-states +--------------------- + +C-states, or idling states of the processor, especially C1E and deeper sleep +states may be problematic for TSC as well. The TSC may stop advancing in such +a state, resulting in a TSC which is behind that of other CPUs when execution +is resumed. Such CPUs must be detected and flagged by the operating system +based on CPU and chipset identifications. + +The TSC in such a case may be corrected by catching it up to a known external +clocksource. + +3.5. TSC frequency change / P-states +------------------------------------ + +To make things slightly more interesting, some CPUs may change frequency. They +may or may not run the TSC at the same rate, and because the frequency change +may be staggered or slewed, at some points in time, the TSC rate may not be +known other than falling within a range of values. In this case, the TSC will +not be a stable time source, and must be calibrated against a known, stable, +external clock to be a usable source of time. + +Whether the TSC runs at a constant rate or scales with the P-state is model +dependent and must be determined by inspecting CPUID, chipset or vendor +specific MSR fields. + +In addition, some vendors have known bugs where the P-state is actually +compensated for properly during normal operation, but when the processor is +inactive, the P-state may be raised temporarily to service cache misses from +other processors. In such cases, the TSC on halted CPUs could advance faster +than that of non-halted processors. AMD Turion processors are known to have +this problem. + +3.6. TSC and STPCLK / T-states +------------------------------ + +External signals given to the processor may also have the effect of stopping +the TSC. This is typically done for thermal emergency power control to prevent +an overheating condition, and typically, there is no way to detect that this +condition has happened. + +3.7. TSC virtualization - VMX +----------------------------- + +VMX provides conditional trapping of RDTSC, RDMSR, WRMSR and RDTSCP +instructions, which is enough for full virtualization of TSC in any manner. In +addition, VMX allows passing through the host TSC plus an additional TSC_OFFSET +field specified in the VMCS. Special instructions must be used to read and +write the VMCS field. + +3.8. TSC virtualization - SVM +----------------------------- + +SVM provides conditional trapping of RDTSC, RDMSR, WRMSR and RDTSCP +instructions, which is enough for full virtualization of TSC in any manner. In +addition, SVM allows passing through the host TSC plus an additional offset +field specified in the SVM control block. + +3.9. TSC feature bits in Linux +------------------------------ + +In summary, there is no way to guarantee the TSC remains in perfect +synchronization unless it is explicitly guaranteed by the architecture. Even +if so, the TSCs in multi-sockets or NUMA systems may still run independently +despite being locally consistent. + +The following feature bits are used by Linux to signal various TSC attributes, +but they can only be taken to be meaningful for UP or single node systems. + +========================= ======================================= +X86_FEATURE_TSC The TSC is available in hardware +X86_FEATURE_RDTSCP The RDTSCP instruction is available +X86_FEATURE_CONSTANT_TSC The TSC rate is unchanged with P-states +X86_FEATURE_NONSTOP_TSC The TSC does not stop in C-states +X86_FEATURE_TSC_RELIABLE TSC sync checks are skipped (VMware) +========================= ======================================= + +4. Virtualization Problems +========================== + +Timekeeping is especially problematic for virtualization because a number of +challenges arise. The most obvious problem is that time is now shared between +the host and, potentially, a number of virtual machines. Thus the virtual +operating system does not run with 100% usage of the CPU, despite the fact that +it may very well make that assumption. It may expect it to remain true to very +exacting bounds when interrupt sources are disabled, but in reality only its +virtual interrupt sources are disabled, and the machine may still be preempted +at any time. This causes problems as the passage of real time, the injection +of machine interrupts and the associated clock sources are no longer completely +synchronized with real time. + +This same problem can occur on native hardware to a degree, as SMM mode may +steal cycles from the naturally on X86 systems when SMM mode is used by the +BIOS, but not in such an extreme fashion. However, the fact that SMM mode may +cause similar problems to virtualization makes it a good justification for +solving many of these problems on bare metal. + +4.1. Interrupt clocking +----------------------- + +One of the most immediate problems that occurs with legacy operating systems +is that the system timekeeping routines are often designed to keep track of +time by counting periodic interrupts. These interrupts may come from the PIT +or the RTC, but the problem is the same: the host virtualization engine may not +be able to deliver the proper number of interrupts per second, and so guest +time may fall behind. This is especially problematic if a high interrupt rate +is selected, such as 1000 HZ, which is unfortunately the default for many Linux +guests. + +There are three approaches to solving this problem; first, it may be possible +to simply ignore it. Guests which have a separate time source for tracking +'wall clock' or 'real time' may not need any adjustment of their interrupts to +maintain proper time. If this is not sufficient, it may be necessary to inject +additional interrupts into the guest in order to increase the effective +interrupt rate. This approach leads to complications in extreme conditions, +where host load or guest lag is too much to compensate for, and thus another +solution to the problem has risen: the guest may need to become aware of lost +ticks and compensate for them internally. Although promising in theory, the +implementation of this policy in Linux has been extremely error prone, and a +number of buggy variants of lost tick compensation are distributed across +commonly used Linux systems. + +Windows uses periodic RTC clocking as a means of keeping time internally, and +thus requires interrupt slewing to keep proper time. It does use a low enough +rate (ed: is it 18.2 Hz?) however that it has not yet been a problem in +practice. + +4.2. TSC sampling and serialization +----------------------------------- + +As the highest precision time source available, the cycle counter of the CPU +has aroused much interest from developers. As explained above, this timer has +many problems unique to its nature as a local, potentially unstable and +potentially unsynchronized source. One issue which is not unique to the TSC, +but is highlighted because of its very precise nature is sampling delay. By +definition, the counter, once read is already old. However, it is also +possible for the counter to be read ahead of the actual use of the result. +This is a consequence of the superscalar execution of the instruction stream, +which may execute instructions out of order. Such execution is called +non-serialized. Forcing serialized execution is necessary for precise +measurement with the TSC, and requires a serializing instruction, such as CPUID +or an MSR read. + +Since CPUID may actually be virtualized by a trap and emulate mechanism, this +serialization can pose a performance issue for hardware virtualization. An +accurate time stamp counter reading may therefore not always be available, and +it may be necessary for an implementation to guard against "backwards" reads of +the TSC as seen from other CPUs, even in an otherwise perfectly synchronized +system. + +4.3. Timespec aliasing +---------------------- + +Additionally, this lack of serialization from the TSC poses another challenge +when using results of the TSC when measured against another time source. As +the TSC is much higher precision, many possible values of the TSC may be read +while another clock is still expressing the same value. + +That is, you may read (T,T+10) while external clock C maintains the same value. +Due to non-serialized reads, you may actually end up with a range which +fluctuates - from (T-1.. T+10). Thus, any time calculated from a TSC, but +calibrated against an external value may have a range of valid values. +Re-calibrating this computation may actually cause time, as computed after the +calibration, to go backwards, compared with time computed before the +calibration. + +This problem is particularly pronounced with an internal time source in Linux, +the kernel time, which is expressed in the theoretically high resolution +timespec - but which advances in much larger granularity intervals, sometimes +at the rate of jiffies, and possibly in catchup modes, at a much larger step. + +This aliasing requires care in the computation and recalibration of kvmclock +and any other values derived from TSC computation (such as TSC virtualization +itself). + +4.4. Migration +-------------- + +Migration of a virtual machine raises problems for timekeeping in two ways. +First, the migration itself may take time, during which interrupts cannot be +delivered, and after which, the guest time may need to be caught up. NTP may +be able to help to some degree here, as the clock correction required is +typically small enough to fall in the NTP-correctable window. + +An additional concern is that timers based off the TSC (or HPET, if the raw bus +clock is exposed) may now be running at different rates, requiring compensation +in some way in the hypervisor by virtualizing these timers. In addition, +migrating to a faster machine may preclude the use of a passthrough TSC, as a +faster clock cannot be made visible to a guest without the potential of time +advancing faster than usual. A slower clock is less of a problem, as it can +always be caught up to the original rate. KVM clock avoids these problems by +simply storing multipliers and offsets against the TSC for the guest to convert +back into nanosecond resolution values. + +4.5. Scheduling +--------------- + +Since scheduling may be based on precise timing and firing of interrupts, the +scheduling algorithms of an operating system may be adversely affected by +virtualization. In theory, the effect is random and should be universally +distributed, but in contrived as well as real scenarios (guest device access, +causes of virtualization exits, possible context switch), this may not always +be the case. The effect of this has not been well studied. + +In an attempt to work around this, several implementations have provided a +paravirtualized scheduler clock, which reveals the true amount of CPU time for +which a virtual machine has been running. + +4.6. Watchdogs +-------------- + +Watchdog timers, such as the lock detector in Linux may fire accidentally when +running under hardware virtualization due to timer interrupts being delayed or +misinterpretation of the passage of real time. Usually, these warnings are +spurious and can be ignored, but in some circumstances it may be necessary to +disable such detection. + +4.7. Delays and precision timing +-------------------------------- + +Precise timing and delays may not be possible in a virtualized system. This +can happen if the system is controlling physical hardware, or issues delays to +compensate for slower I/O to and from devices. The first issue is not solvable +in general for a virtualized system; hardware control software can't be +adequately virtualized without a full real-time operating system, which would +require an RT aware virtualization platform. + +The second issue may cause performance problems, but this is unlikely to be a +significant issue. In many cases these delays may be eliminated through +configuration or paravirtualization. + +4.8. Covert channels and leaks +------------------------------ + +In addition to the above problems, time information will inevitably leak to the +guest about the host in anything but a perfect implementation of virtualized +time. This may allow the guest to infer the presence of a hypervisor (as in a +red-pill type detection), and it may allow information to leak between guests +by using CPU utilization itself as a signalling channel. Preventing such +problems would require completely isolated virtual time which may not track +real time any longer. This may be useful in certain security or QA contexts, +but in general isn't recommended for real-world deployment scenarios. --- linux-5.15.0.orig/Documentation/x86/index.rst +++ linux-5.15.0/Documentation/x86/index.rst @@ -37,3 +37,4 @@ sgx features elf_auxvec + xstate --- linux-5.15.0.orig/Documentation/x86/mds.rst +++ linux-5.15.0/Documentation/x86/mds.rst @@ -95,6 +95,9 @@ mds_clear_cpu_buffers() +Also macro CLEAR_CPU_BUFFERS can be used in ASM late in exit-to-user path. +Other than CFLAGS.ZF, this macro doesn't clobber any registers. + The mitigation is invoked on kernel/userspace, hypervisor/guest and C-state (idle) transitions. @@ -138,17 +141,30 @@ When transitioning from kernel to user space the CPU buffers are flushed on affected CPUs when the mitigation is not disabled on the kernel - command line.

Righi + +Overview +======== + +Each Ubuntu kernel needs to maintain its own .config for each supported +architecture and each flavour. + +Every time a new patch is applied or a kernel is rebased on top of a new +one, we need to update the .config's accordingly (config options can be +added, removed and also renamed). + +So, we need to make sure that some critical config options are always +matching the desired value in order to have a functional kernel. + +State of the art +================ + +At the moment configs are maintained as a set of Kconfig chunks (inside +`debian./config/`): a global one, plus per-arch / per-flavour +chunks. + +In addition to that, we need to maintain also a file called +'annotations'; the purpose of this file is to make sure that some +critical config options are not silently removed or changed when the +real .config is re-generated (for example after a rebase or after +applying a new set of patches). + +The main problem with this approach is that, often, we have duplicate +information that is stored both in the Kconfig chunks *and* in the +annotations files and, at the same time, the whole .config's information +is distributed between Kconfig chunks and annotations, making it hard to +maintain, review and manage in general. + +Proposed solution +================= + +The proposed solution is to store all the config information into the +"annotations" format and get rid of the config chunks (basically the +real .config's can be produced "compiling" annotations). + +Implementation +============== + +To help the management of the annotations an helper script is provided +(`debian/scripts/misc/annotations`): + +``` +usage: annotations [-h] [--version] [--file FILE] [--arch ARCH] [--flavour FLAVOUR] [--config CONFIG] + (--query | --export | --import FILE | --update FILE | --check FILE) + +Manage Ubuntu kernel .config and annotations + +options: + -h, --help show this help message and exit + --version, -v show program's version number and exit + --file FILE, -f FILE Pass annotations or .config file to be parsed + --arch ARCH, -a ARCH Select architecture + --flavour FLAVOUR, -l FLAVOUR + Select flavour (default is "generic") + --config CONFIG, -c CONFIG + Select a specific config option + +Action: + --query, -q Query annotations + --export, -e Convert annotations to .config format + --import FILE, -i FILE + Import a full .config for a specific arch and flavour into annotations + --update FILE, -u FILE + Import a partial .config into annotations (only resync configs specified in FILE) + --check FILE, -k FILE + Validate kernel .config with annotations +``` + +This script allows to query config settings (per arch/flavour/config), +export them into the Kconfig format (generating the real .config files) +and check if the final .config matches the rules defined in the +annotations. + +Examples (annotations is defined as an alias to `debian/scripts/annotations`): + + - Show settings for `CONFIG_DEBUG_INFO_BTF` for master kernel across all the + supported architectures and flavours: + +``` +$ annotations --query --config CONFIG_DEBUG_INFO_BTF +{ + "policy": { + "amd64": "y", + "arm64": "y", + "armhf": "n", + "ppc64el": "y", + "riscv64": "y", + "s390x": "y" + }, + "note": "'Needs newer pahole for armhf'" +} +``` + + - Dump kernel .config for arm64 and flavour generic-64k: + +``` +$ annotations --arch arm64 --flavour generic-64k --export +CONFIG_DEBUG_FS=y +CONFIG_DEBUG_KERNEL=y +CONFIG_COMPAT=y +... +``` + + - Update annotations file with a new kernel .config for amd64 flavour + generic: + +``` +$ annotations --arch amd64 --flavour generic --import build/.config +``` + +Moreover, an additional kernelconfig commands are provided +(via debian/rules targets): + - `migrateconfigs`: automatically merge all the previous configs into + annotations (local changes still need to be committed) + +Annotations headers +=================== + +The main annotations file should contain a header to define the architectures +and flavours that are supported. + +Here is the format of the header for the generic kernel: +``` +# Menu: HEADER +# FORMAT: 4 +# ARCH: amd64 arm64 armhf ppc64el riscv64 s390x +# FLAVOUR: amd64-generic arm64-generic arm64-generic-64k armhf-generic armhf-generic-lpae ppc64el-generic riscv64-generic s390x-generic + +``` + +Example header of a derivative (linux-aws): +``` +# Menu: HEADER +# FORMAT: 4 +# ARCH: amd64 arm64 +# FLAVOUR: amd64-aws arm64-aws +# FLAVOUR_DEP: {'amd64-aws': 'amd64-generic', 'arm64-aws': 'arm64-generic'} + +include "../../debian.master/config/annotations" + +# Below you can define only the specific linux-aws configs that differ from linux generic + +``` + +Pros and Cons +============= + + Pros: + - avoid duplicate information in .config's and annotations + - allow to easily define groups of config settings (for a specific + environment or feature, such as annotations.clouds, annotations.ubuntu, + annotations.snapd, etc.) + - config options are more accessible, easy to change and review + - we can easily document how config options are managed (and external + contributors won't be discouraged anymore when they need to to change a + config option) + + Cons: + - potential regressions: the new tool/scripts can have potential bugs, + so we could experience regressions due to some missed config changes + - kernel team need to understand the new process (even if everything + is transparent, kernel cranking process is the same, there might be + corner cases that need to be addressed and resolved manually) + +TODO +==== + + - Migrate all flavour and arch definitions into annotations (rather + than having this information defined in multiple places inside + debian/scripts); right now this information is "partially" migrated, + meaning that we need to define arches and flavours in the headers + section of annotations (so that the annotations tool can figure out + the list of supported arches and flavours), but arches and flavours + are still defined elsewhere, ideally we would like to have arches and + flavours defined only in one place: annotations. ---

However, there were some difficult +mainteneance issues with regard to packaging, make rules, and scripts. This +re-implementation of the sub-flavours philosophy is hopefully simpler, +and retrofitable to all releases. + +A module inclusion list looks at the problem of of constructing a package +from the perspective of what modules do we _want_ in the package, as opposed +to what modules we _don't_ want. As the kernel matures, more and more devices are added +which makes the problem of configuration maintenance a real pain in the ass. +If we took the approach of disabling all of the config options that we don't want, +then the differences between flavours will quickly become quite large, making +it difficult to quickly compare the individual flavour configs. Each time a +new config option is added then we also have to make a decision about disabling in +order to continue to keep the minimal number of modules. + +A module inclusion list is applied on a per-flavour basis. For example, +debian./control.d/${flavour}.inclusion-list. For example, the +config for virtual is very close to server and generic, but the inclusion list +causes the virtual package to be constructed with _only_ the modules described +in the inclusion list. + +The inclusion list format is a simple bash regular expression list of files. For example, + +arch/*/{crypto,kernel,oprofile} +drivers/acpi/* +drivers/ata/ahci.ko + +These 3 regular expression forms are suitable for expansion by bash and as inputs to 'find'. +See debian/scripts/module-inclusion for details. + +There are 2 log files created as a side effect of the application of the module +inclusion list; $(flavour).inclusion-list.log and $(flavour).depmod.log. + +$(flavour).inclusion-list.log : This log is created while the inclusion list +modules are being copied. If any are missing, then those warnings go in this log. +While its not considered a fatal error, you should endevour to correct your inclusion +list such that there are no missing modules. + +$(flavour).depmod.log : The log is created as a result of running depmod on the +resulting set of modules. If there are missing symbols then you'll find that information +here. Again, you should modify your inclusion list such that there are no missing +symbols. + +Tim Gardner +June 2, 2010 --- linux-5.15.0.orig/debian/gbp.conf +++ linux-5.15.0/debian/gbp.conf @@ -0,0 +1,2 @@ +[buildpackage] +debian-tag = Ubuntu-%(version)s --- linux-5.15.0.orig/debian/linux-cloud-tools-common.hv-fcopy-daemon.service +++ linux-5.15.0/debian/linux-cloud-tools-common.hv-fcopy-daemon.service @@ -0,0 +1,14 @@ +# On Azure/Hyper-V systems start the hv_fcopy_daemon +# +# author "Andy Whitcroft " +[Unit] +Description=Hyper-V File Copy Protocol Daemon +ConditionVirtualization=microsoft +ConditionPathExists=/dev/vmbus/hv_fcopy +BindsTo=sys-devices-virtual-misc-vmbus\x21hv_fcopy.device + +[Service] +ExecStart=/usr/sbin/hv_fcopy_daemon -n + +[Install] +WantedBy=multi-user.target --- linux-5.15.0.orig/debian/linux-cloud-tools-common.hv-fcopy-daemon.udev +++ linux-5.15.0/debian/linux-cloud-tools-common.hv-fcopy-daemon.udev @@ -0,0 +1 @@ +SUBSYSTEM=="misc", KERNEL=="vmbus/hv_fcopy", TAG+="systemd", ENV{SYSTEMD_WANTS}+="hv-fcopy-daemon.service" --- linux-5.15.0.orig/debian/linux-cloud-tools-common.hv-fcopy-daemon.upstart +++ linux-5.15.0/debian/linux-cloud-tools-common.hv-fcopy-daemon.upstart @@ -0,0 +1,22 @@ +# On Azure/Hyper-V systems start the hv_fcopy_daemon +# +description "Hyper-V File Copy Protocol Daemon" +author "Andy Whitcroft " + +start on runlevel [2345] +stop on runlevel [!2345] +console log + +pre-start script + if [ -e "/etc/default/hv-kvp-daemon-init" ];

Hence it is extremely hard - * to produce truly random numbers on a computer --- as opposed to - * pseudo-random numbers, which can easily generated by using a - * algorithm. Unfortunately, it is very easy for attackers to guess - * the sequence of pseudo-random number generators, and for some - * applications this is not acceptable. So instead, we must try to - * gather "environmental noise" from the computer's environment, which - * must be hard for outside attackers to observe, and use that to - * generate random numbers. In a Unix environment, this is best done - * from inside the kernel. - * - * Sources of randomness from the environment include inter-keyboard - * timings, inter-interrupt timings from some interrupts, and other - * events which are both (a) non-deterministic and (b) hard for an - * outside observer to measure. Randomness from these sources are - * added to an "entropy pool", which is mixed using a CRC-like function. - * This is not cryptographically strong, but it is adequate assuming - * the randomness is not chosen maliciously, and it is fast enough that - * the overhead of doing it on every interrupt is very reasonable. - * As random bytes are mixed into the entropy pool, the routines keep - * an *estimate* of how many bits of randomness have been stored into - * the random number generator's internal state. - * - * When random bytes are desired, they are obtained by taking the SHA - * hash of the contents of the "entropy pool". The SHA hash avoids - * exposing the internal state of the entropy pool. It is believed to - * be computationally infeasible to derive any useful information - * about the input of SHA from its output. Even if it is possible to - * analyze SHA in some clever way, as long as the amount of data - * returned from the generator is less than the inherent entropy in - * the pool, the output data is totally unpredictable. For this - * reason, the routine decreases its internal estimate of how many - * bits of "true randomness" are contained in the entropy pool as it - * outputs random numbers. - * - * If this estimate goes to zero, the routine can still generate - * random numbers; however, an attacker may (at least in theory) be - * able to infer the future output of the generator from prior - * outputs. This requires successful cryptanalysis of SHA, which is - * not believed to be feasible, but there is a remote possibility. - * Nonetheless, these numbers should be useful for the vast majority - * of purposes. - * - * Exported interfaces ---- output - * =============================== - * - * There are four exported interfaces; two for use within the kernel, - * and two or use from userspace. - * - * Exported interfaces ---- userspace output - * ----------------------------------------- - * - * The userspace interfaces are two character devices /dev/random and - * /dev/urandom. /dev/random is suitable for use when very high - * quality randomness is desired (for example, for key generation or - * one-time pads), as it will only return a maximum of the number of - * bits of randomness (as estimated by the random number generator) - * contained in the entropy pool. - * - * The /dev/urandom device does not have this limit, and will return - * as many bytes as are requested. As more and more random bytes are - * requested without giving time for the entropy pool to recharge, - * this will result in random numbers that are merely cryptographically - * strong. For many applications, however, this is acceptable. - * - * Exported interfaces ---- kernel output - * -------------------------------------- - * - * The primary kernel interface is - * - * void get_random_bytes(void *buf, int nbytes); - * - * This interface will return the requested number of random bytes, - * and place it in the requested buffer. This is equivalent to a - * read from /dev/urandom. - * - * For less critical applications, there are the functions: - * - * u32 get_random_u32() - * u64 get_random_u64() - * unsigned int get_random_int() - * unsigned long get_random_long() - * - * These are produced by a cryptographic RNG seeded from get_random_bytes, - * and so do not deplete the entropy pool as much. These are recommended - * for most in-kernel operations *if the result is going to be stored in - * the kernel*. - * - * Specifically, the get_random_int() family do not attempt to do - * "anti-backtracking". If you capture the state of the kernel (e.g. - * by snapshotting the VM), you can figure out previous get_random_int() - * return values. But if the value is stored in the kernel anyway, - * this is not a problem. - * - * It *is* safe to expose get_random_int() output to attackers (e.g. as - * network cookies); given outputs 1..n, it's not feasible to predict - * outputs 0 or n+1. The only concern is an attacker who breaks into - * the kernel later; the get_random_int() engine is not reseeded as - * often as the get_random_bytes() one. - * - * get_random_bytes() is needed for keys that need to stay secret after - * they are erased from the kernel. For example, any key that will - * be wrapped and stored encrypted. And session encryption keys: we'd - * like to know that after the session is closed and the keys erased, - * the plaintext is unrecoverable to someone who recorded the ciphertext. - * - * But for network ports/cookies, stack canaries, PRNG seeds, address - * space layout randomization, session *authentication* keys, or other - * applications where the sensitive data is stored in the kernel in - * plaintext for as long as it's sensitive, the get_random_int() family - * is just fine. - * - * Consider ASLR. We want to keep the address space secret from an - * outside attacker while the process is running, but once the address - * space is torn down, it's of no use to an attacker any more. And it's - * stored in kernel data structures as long as it's alive, so worrying - * about an attacker's ability to extrapolate it from the get_random_int() - * CRNG is silly. - * - * Even some cryptographic keys are safe to generate with get_random_int(). - * In particular, keys for SipHash are generally fine. Here, knowledge - * of the key authorizes you to do something to a kernel object (inject - * packets to a network connection, or flood a hash table), and the - * key is stored with the object being protected. Once it goes away, - * we no longer care if anyone knows the key. - * - * prandom_u32() - * ------------- - * - * For even weaker applications, see the pseudorandom generator - * prandom_u32(), prandom_max(), and prandom_bytes(). If the random - * numbers aren't security-critical at all, these are *far* cheaper. - * Useful for self-tests, random error simulation, randomized backoffs, - * and any other application where you trust that nobody is trying to - * maliciously mess with you by guessing the "random" numbers. - * - * Exported interfaces ---- input - * ============================== - * - * The current exported interfaces for gathering environmental noise - * from the devices are: - * - * void add_device_randomness(const void *buf, unsigned int size); - * void add_input_randomness(unsigned int type, unsigned int code, - * unsigned int value); - * void add_interrupt_randomness(int irq, int irq_flags); - * void add_disk_randomness(struct gendisk *disk); - * - * add_device_randomness() is for adding data to the random pool that - * is likely to differ between two devices (or possibly even per boot). - * This would be things like MAC addresses or serial numbers, or the - * read-out of the RTC. This does *not* add any actual entropy to the - * pool, but it initializes the pool to different values for devices - * that might otherwise be identical and have very little entropy - * available to them (particularly common in the embedded world). - * - * add_input_randomness() uses the input layer interrupt timing, as well as - * the event type information from the hardware. - * - * add_interrupt_randomness() uses the interrupt timing as random - * inputs to the entropy pool. Using the cycle counters and the irq source - * as inputs, it feeds the randomness roughly once a second. - * - * add_disk_randomness() uses what amounts to the seek time of block - * layer request events, on a per-disk_devt basis, as input to the - * entropy pool. Note that high-speed solid state drives with very low - * seek times do not make for good sources of entropy, as their seek - * times are usually fairly consistent. - * - * All of these routines try to estimate how many bits of randomness a - * particular randomness source. They do this by keeping track of the - * first and second order deltas of the event timings. - * - * Ensuring unpredictability at system startup - * ============================================ - * - * When any operating system starts up, it will go through a sequence - * of actions that are fairly predictable by an adversary, especially - * if the start-up does not involve interaction with a human operator. - * This reduces the actual number of bits of unpredictability in the - * entropy pool below the value in entropy_count. In order to - * counteract this effect, it helps to carry information in the - * entropy pool across shut-downs and start-ups. To do this, put the - * following lines an appropriate script which is run during the boot - * sequence: - * - * echo "Initializing random number generator..." - * random_seed=/var/run/random-seed - * # Carry a random seed from start-up to start-up - * # Load and then save the whole entropy pool - * if [ -f $random_seed ]; then - * cat $random_seed >/dev/urandom - * else - * touch $random_seed - * fi - * chmod 600 $random_seed - * dd if=/dev/urandom of=$random_seed count=1 bs=512 - * - * and the following lines in an appropriate script which is run as - * the system is shutdown: - * - * # Carry a random seed from shut-down to start-up - * # Save the whole entropy pool - * echo "Saving random seed..." - * random_seed=/var/run/random-seed - * touch $random_seed - * chmod 600 $random_seed - * dd if=/dev/urandom of=$random_seed count=1 bs=512 - * - * For example, on most modern systems using the System V init - * scripts, such code fragments would be found in - * /etc/rc.d/init.d/random. On older Linux systems, the correct script - * location might be in /etc/rcb.d/rc.local or /etc/rc.d/rc.0. - * - * Effectively, these commands cause the contents of the entropy pool - * to be saved at shut-down time and reloaded into the entropy pool at - * start-up. (The 'dd' in the addition to the bootup script is to - * make sure that /etc/random-seed is different for every start-up, - * even if the system crashes without executing rc.0.) Even with - * complete knowledge of the start-up activities, predicting the state - * of the entropy pool requires knowledge of the previous history of - * the system. - * - * Configuring the /dev/random driver under Linux - * ============================================== - * - * The /dev/random driver under Linux uses minor numbers 8 and 9 of - * the /dev/mem major number (#1). So if your system does not have - * /dev/random and /dev/urandom created already, they can be created - * by using the commands: - * - * mknod /dev/random c 1 8 - * mknod /dev/urandom c 1 9 - * - * Acknowledgements: - * ================= - * - * Ideas for constructing this random number generator were derived - * from Pretty Good Privacy's random number generator, and from private - * discussions with Phil Karn. Colin Plumb provided a faster random - * number generator, which speed up the mixing function of the entropy - * pool, taken from PGPfone. Dale Worley has also contributed many - * useful ideas and suggestions to improve this driver. - * - * Any flaws in the design are solely my responsibility, and should - * not be attributed to the Phil, Colin, or any of authors of PGP. - * - * Further background information on this topic may be obtained from - * RFC 1750, "Randomness Recommendations for Security", by Donald - * Eastlake, Steve Crocker, and Jeff Schiller. + * - Initialization and readiness waiting. + * - Fast key erasure RNG, the "crng". + * - Entropy accumulation and extraction routines. + * - Entropy collection routines. + * - Userspace reader/writer interfaces. + * - Sysctl interface. + * + * The high level overview is that there is one input pool, into which + * various pieces of data are hashed. Prior to initialization, some of that + * data is then "credited" as having a certain number of bits of entropy. + * When enough bits of entropy are available, the hash is finalized and + * handed as a key to a stream cipher that expands it indefinitely for + * various consumers. This key is periodically refreshed as the various + * entropy collectors, described below, add data to the input pool. */ #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt @@ -327,7 +43,6 @@ #include #include #include -#include #include #include #include @@ -335,1223 +50,1089 @@ #include #include #include +#include +#include +#include #include -#include - +#include #include -#include #include #include #include -#define CREATE_TRACE_POINTS -#include - -/* #define ADD_INTERRUPT_BENCH */ - -/* - * Configuration information - */ -#define INPUT_POOL_SHIFT 12 -#define INPUT_POOL_WORDS (1 << (INPUT_POOL_SHIFT-5)) -#define OUTPUT_POOL_SHIFT 10 -#define OUTPUT_POOL_WORDS (1 << (OUTPUT_POOL_SHIFT-5)) -#define EXTRACT_SIZE 10 - - -#define LONGS(x) (((x) + sizeof(unsigned long) - 1)/sizeof(unsigned long)) - -/* - * To allow fractional bits to be tracked, the entropy_count field is - * denominated in units of 1/8th bits. - * - * 2*(ENTROPY_SHIFT + poolbitshift) must <= 31, or the multiply in - * credit_entropy_bits() needs to be 64 bits wide. - */ -#define ENTROPY_SHIFT 3 -#define ENTROPY_BITS(r) ((r)->entropy_count >> ENTROPY_SHIFT) - -/* - * If the entropy count falls under this number of bits, then we - * should wake up processes which are selecting or polling on write - * access to /dev/random. - */ -static int random_write_wakeup_bits = 28 * OUTPUT_POOL_WORDS; - -/* - * Originally, we used a primitive polynomial of degree .poolwords - * over GF(2).

With this idea in + * mind, this file aims to centralize all DCN20 and DCN2.1 (DCN2x) functions + * that require FPU access in a single place. Code in this file follows the + * following code pattern: + * + * 1. Functions that use FPU operations should be isolated in static functions. + * 2. The FPU functions should have the noinline attribute to ensure anything + * that deals with FP register is contained within this call. + * 3. All function that needs to be accessed outside this file requires a + * public interface that not uses any FPU reference. + * 4. Developers **must not** use DC_FP_START/END in this file, but they need + * to ensure that the caller invokes it before access any function available + * in this file. For this reason, public functions in this file must invoke + * dc_assert_fp_enabled(); + * + * Let's expand a little bit more the idea in the code pattern. To fully + * isolate FPU operations in a single place, we must avoid situations where + * compilers spill FP values to registers due to FP enable in a specific C + * file. Note that even if we isolate all FPU functions in a single file and + * call its interface from other files, the compiler might enable the use of + * FPU before we call DC_FP_START. Nevertheless, it is the programmer's + * responsibility to invoke DC_FP_START/END in the correct place. To highlight + * situations where developers forgot to use the FP protection before calling + * the DC FPU interface functions, we introduce a helper that checks if the + * function is invoked under FP protection.
