SPDX-License-Identifier: GPL-2.0 + +========================================== +ARM Mali-C55 Image Signal Processor driver +========================================== + +Introduction +============ + +This file documents the driver for ARM's Mali-C55 Image Signal Processor. The +driver is located under drivers/media/platform/arm/mali-c55. + +The Mali-C55 ISP receives data in either raw Bayer format or RGB/YUV format from +sensors through either a parallel interface or a memory bus before processing it +and outputting it through an internal DMA engine. Two output pipelines are +possible (though one may not be fitted, depending on the implementation). These +are referred to as "Full resolution" and "Downscale", but the naming is historic +and both pipes are capable of cropping/scaling operations. The full resolution +pipe is also capable of outputting RAW data, bypassing much of the ISP's +processing. The downscale pipe cannot output RAW data. An integrated test +pattern generator can be used to drive the ISP and produce image data in the +absence of a connected camera sensor. The driver module is named mali_c55, and +is enabled through the CONFIG_VIDEO_MALI_C55 config option. + +The driver implements V4L2, Media Controller and V4L2 Subdevice interfaces and +expects camera sensors connected to the ISP to have V4L2 subdevice interfaces. + +Mali-C55 ISP hardware +===================== + +A high level functional view of the Mali-C55 ISP is presented below.

In the examples below, configuring the +media graph is done with the v4l-utils [1]_ package's media-ctl utility. +Capturing the images is done with yavta [2]_. + +Configuring the input source +---------------------------- + +The first step is to set the input source that we wish by enabling the correct +media link.

To facilitate this we need +to enable links to the video devices that we want to use. In the example below +we enable the links to both of the image capture video devices + +.. code-block:: none + + media-ctl -l "'mali-c55 resizer fr':1->'mali-c55 fr':0[1]" + media-ctl -l "'mali-c55 resizer ds':1->'mali-c55 ds':0[1]" + +Capturing bayer data from the source and processing to RGB/YUV +-------------------------------------------------------------- + +To capture 1920x1080 bayer data from the source and push it through the ISP's +full processing pipeline, we configure the data formats appropriately on the +source, ISP and resizer subdevices and set the FR resizer's routing to select +processed data.

For the best image +result the scaling ratio for each direction should be the same. To configure +scaling we use the compose rectangle on the resizer's sink pad: + +.. code-block:: none + + media-ctl -V "'mali-c55 resizer fr':0[fmt:RGB121212_1X36/1920x1080 crop:(0,0)/1920x1080 compose:(0,0)/640x480]" + media-ctl -V "'mali-c55 resizer fr':1[fmt:RGB121212_1X36/640x480]" + yavta -f RGB565 -s 640x480 -c10 /dev/video0 + +Capturing images in YUV formats +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +If we need to output YUV data rather than RGB the color space conversion block +needs to be active, which is achieved by setting MEDIA_BUS_FMT_YUV10_1X30 on the +resizer's source pad. We can then configure a capture format like NV12 (here in +its multi-planar variant) + +.. code-block:: none + + media-ctl -V "'mali-c55 resizer fr':1[fmt:YUV10_1X30/1920x1080]" + yavta -f NV12M -s 1920x1080 -c10 /dev/video0 + +Capturing RGB data from the source and processing it with the resizers +---------------------------------------------------------------------- + +The Mali-C55 ISP can work with sensors capable of outputting RGB data.

Since each format +provides an API using a common set of names there can be only one format active +within a compilation unit. This design avoids function pointers around the low +level API. + +Instead the function pointers can end up at the higher level API (i.e. +map/unmap, etc.) and the per-format code can be directly inlined into the +per-format compilation unit. For something like IOMMU each format will be +compiled into a per-format IOMMU operations kernel module. + +For this to work the .c file for each compilation unit will include both the +format headers and the generic code for the implementation. For instance in an +implementation compilation unit the headers would normally be included as +follows: + +generic_pt/fmt/iommu_amdv1.c:: + + #include + #include "defs_amdv1.h" + #include "../pt_defs.h" + #include "amdv1.h" + #include "../pt_common.h" + #include "../pt_iter.h" + #include "../iommu_pt.h" /* The IOMMU implementation */ + +iommu_pt.h includes definitions that will generate the operations functions for +map/unmap/etc. using the definitions provided by AMDv1. The resulting module +will have exported symbols named like pt_iommu_amdv1_init(). + +Refer to drivers/iommu/generic_pt/fmt/iommu_template.h for an example of how the +IOMMU implementation uses multi-compilation to generate per-format ops structs +pointers. + +The format code is written so that the common names arise from #defines to +distinct format specific names. This is intended to aid debuggability by +avoiding symbol clashes across all the different formats. + +Exported symbols and other global names are mangled using a per-format string +via the NS() helper macro. + +The format uses struct pt_common as the top-level struct for the table, +and each format will have its own struct pt_xxx which embeds it to store +format-specific information. + +The implementation will further wrap struct pt_common in its own top-level +struct, such as struct pt_iommu_amdv1. + +Format functions at the struct pt_common level +---------------------------------------------- + +.. kernel-doc:: include/linux/generic_pt/common.h + :identifiers: +.. kernel-doc:: drivers/iommu/generic_pt/pt_common.h + +Iteration Helpers +----------------- + +.. kernel-doc:: drivers/iommu/generic_pt/pt_iter.h + +Writing a Format +---------------- + +It is best to start from a simple format that is similar to the target. x86_64 +is usually a good reference for something simple, and AMDv1 is something fairly +complete. + +The required inline functions need to be implemented in the format header. +These should all follow the standard pattern of:: + + static inline pt_oaddr_t amdv1pt_entry_oa(const struct pt_state *pts) + { + [..] + } + #define pt_entry_oa amdv1pt_entry_oa + +where a uniquely named per-format inline function provides the implementation +and a define maps it to the generic name. This is intended to make debug symbols +work better. inline functions should always be used as the prototypes in +pt_common.h will cause the compiler to validate the function signature to +prevent errors. + +Review pt_fmt_defaults.h to understand some of the optional inlines. + +Once the format compiles then it should be run through the generic page table +kunit test in kunit_generic_pt.h using kunit. For example:: + + $ tools/testing/kunit/kunit.py run --build_dir build_kunit_x86_64 --arch x86_64 --kunitconfig ./drivers/iommu/generic_pt/.kunitconfig amdv1_fmt_test.* + [...] + [11:15:08] Testing complete. Ran 9 tests: passed: 9 + [11:15:09] Elapsed time: 3.137s total, 0.001s configuring, 2.368s building, 0.311s running + +The generic tests are intended to prove out the format functions and give +clearer failures to speed up finding the problems. Once those pass then the +entire kunit suite should be run. + +IOMMU Invalidation Features +--------------------------- + +Invalidation is how the page table algorithms synchronize with a HW cache of the +page table memory, typically called the TLB (or IOTLB for IOMMU cases). + +The TLB can store present PTEs, non-present PTEs and table pointers, depending +on its design. Every HW has its own approach on how to describe what has changed +to have changed items removed from the TLB. + +PT_FEAT_FLUSH_RANGE +~~~~~~~~~~~~~~~~~~~ + +PT_FEAT_FLUSH_RANGE is the easiest scheme to understand. It tries to generate a +single range invalidation for each operation, over-invalidating if there are +gaps of VA that don't need invalidation. This trades off impacted VA for number +of invalidation operations. It does not keep track of what is being invalidated; +however, if pages have to be freed then page table pointers have to be cleaned +from the walk cache. The range can start/end at any page boundary. + +PT_FEAT_FLUSH_RANGE_NO_GAPS +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +PT_FEAT_FLUSH_RANGE_NO_GAPS is similar to PT_FEAT_FLUSH_RANGE; however, it tries +to minimize the amount of impacted VA by issuing extra flush operations. This is +useful if the cost of processing VA is very high, for instance because a +hypervisor is processing the page table with a shadowing algorithm. diff --git a/Documentation/driver-api/gpio/index.rst b/Documentation/driver-api/gpio/index.rst index 87929840e85a..bee58f709b9a 100644 --- a/Documentation/driver-api/gpio/index.rst +++ b/Documentation/driver-api/gpio/index.rst @@ -15,6 +15,7 @@ Contents: legacy-boards drivers-on-gpio bt8xxgpio + pca953x Core ==== diff --git a/Documentation/driver-api/gpio/pca953x.rst b/Documentation/driver-api/gpio/pca953x.rst new file mode 100644 index 000000000000..4bd7cf1120cb --- /dev/null +++ b/Documentation/driver-api/gpio/pca953x.rst @@ -0,0 +1,552 @@ +============================================ +PCA953x I²C GPIO expander compatibility list +============================================ + +:Author: Levente Révész + +I went through all the datasheets and created this note listing +chip functions and register layouts. + +Overview of chips +================= + +Chips with the basic 4 registers +-------------------------------- + +These chips have 4 register banks: input, output, invert and direction. +Each of these banks contains (lines/8) registers, one for each GPIO port. + +Banks offset is always a power of 2: + +- 4 lines -> bank offset is 1 +- 8 lines -> bank offset is 1 +- 16 lines -> bank offset is 2 +- 24 lines -> bank offset is 4 +- 32 lines -> bank offset is 4 +- 40 lines -> bank offset is 8 + +For example, register layout of GPIO expander with 24 lines: + ++------+-----------------+--------+ +| addr | function | bank | ++======+=================+========+ +| 00 | input port0 | | ++------+-----------------+ | +| 01 | input port1 | bank 0 | ++------+-----------------+ | +| 02 | input port2 | | ++------+-----------------+--------+ +| 03 | n/a | | ++------+-----------------+--------+ +| 04 | output port0 | | ++------+-----------------+ | +| 05 | output port1 | bank 1 | ++------+-----------------+ | +| 06 | output port2 | | ++------+-----------------+--------+ +| 07 | n/a | | ++------+-----------------+--------+ +| 08 | invert port0 | | ++------+-----------------+ | +| 09 | invert port1 | bank 2 | ++------+-----------------+ | +| 0A | invert port2 | | ++------+-----------------+--------+ +| 0B | n/a | | ++------+-----------------+--------+ +| 0C | direction port0 | | ++------+-----------------+ | +| 0D | direction port1 | bank 3 | ++------+-----------------+ | +| 0E | direction port2 | | ++------+-----------------+--------+ +| 0F | n/a | | ++------+-----------------+--------+ + +.. note:: + This is followed by all supported chips, except by pcal6534. + +The table below shows the offsets for each of the compatible chips: + +========== ===== ========= ===== ====== ====== ========= +compatible lines interrupt input output invert direction +========== ===== ========= ===== ====== ====== ========= +pca9536 4 no 00 01 02 03 +pca9537 4 yes 00 01 02 03 +pca6408 8 yes 00 01 02 03 +tca6408 8 yes 00 01 02 03 +pca9534 8 yes 00 01 02 03 +pca9538 8 yes 00 01 02 03 +pca9554 8 yes 00 01 02 03 +tca9554 8 yes 00 01 02 03 +pca9556 8 no 00 01 02 03 +pca9557 8 no 00 01 02 03 +pca6107 8 yes 00 01 02 03 +pca6416 16 yes 00 02 04 06 +tca6416 16 yes 00 02 04 06 +pca9535 16 yes 00 02 04 06 +pca9539 16 yes 00 02 04 06 +tca9539 16 yes 00 02 04 06 +pca9555 16 yes 00 02 04 06 +max7318 16 yes 00 02 04 06 +tca6424 24 yes 00 04 08 0C +========== ===== ========= ===== ====== ====== ========= + +Chips with additional timeout_en register +----------------------------------------- + +These Maxim chips have a bus timeout function which can be enabled in +the timeout_en register.

Using perf to collect perf data that may be used +to generate a "flamegraph" for work Linux must perform on behalf of your +test is a really meaningful way to compare the relative health of the +system and how switching NFSD's IO mode changes what is observed. + +If NFSD_IO_DIRECT is specified by writing 2 (or 3 and 4 for WRITE) to +NFSD's debugfs interfaces, ideally the IO will be aligned relative to +the underlying block device's logical_block_size.

A contributor may use +this document to set their expectations and avoid common mistakes. +A maintainer may use these profiles to look across subsystems for +opportunities to converge on best common practices. + +Overview +-------- +The Network File System (NFS) is a standardized family of network +protocols that enable access to files across a set of network- +connected peer hosts. Applications on NFS clients access files that +reside on file systems that are shared by NFS servers. A single +network peer can act as both an NFS client and an NFS server. + +NFSD refers to the NFS server implementation included in the Linux +kernel. An in-kernel NFS server has fast access to files stored +in file systems local to that server. NFSD can share files stored +on most of the file system types native to Linux, including xfs, +ext4, btrfs, and tmpfs. + +Mailing list +------------ +The linux-nfs@vger.kernel.org mailing list is a public list. Its +purpose is to enable collaboration among developers working on the +Linux NFS stack, both client and server. It is not a place for +conversations that are not related directly to the Linux NFS stack. + +The linux-nfs mailing list is archived on `lore.kernel.org `_. + +The Linux NFS community does not have any chat room. + +Reporting bugs +-------------- +If you experience an NFSD-related bug on a distribution-built +kernel, please start by working with your Linux distributor. + +Bug reports against upstream Linux code bases are welcome on the +linux-nfs@vger.kernel.org mailing list, where some active triage +can be done. NFSD bugs may also be reported in the Linux kernel +community's bugzilla at: + + https://bugzilla.kernel.org + +Please file NFSD-related bugs under the "Filesystems/NFSD" +component. In general, including as much detail as possible is a +good start, including pertinent system log messages from both +the client and server. + +User space software related to NFSD, such as mountd or the exportfs +command, is contained in the nfs-utils package. Report problems +with those components to linux-nfs@vger.kernel.org. You might be +directed to move the report to a specific bug tracker. + +Contributor's Guide +------------------- + +Standards compliance +~~~~~~~~~~~~~~~~~~~~ +The priority is for NFSD to interoperate fully with the Linux NFS +client. We also test against other popular NFS client implementa- +tions regularly at NFS bake-a-thon events (also known as plug- +fests). Non-Linux NFS clients are not part of upstream NFSD CI/CD. + +The NFSD community strives to provide an NFS server implementation +that interoperates with all standards-compliant NFS client +implementations. This is done by staying as close as is sensible to +the normative mandates in the IETF's published NFS, RPC, and GSS-API +standards. + +It is always useful to reference an RFC and section number in a code +comment where behavior deviates from the standard (and even when the +behavior is compliant but the implementation is obfuscatory). + +On the rare occasion when a deviation from standard-mandated +behavior is needed, brief documentation of the use case or +deficiencies in the standard is a required part of in-code +documentation. + +Care must always be taken to avoid leaking local error codes (ie, +errnos) to clients of NFSD. A proper NFS status code is always +required in NFS protocol replies. + +NFSD administrative interfaces +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +NFSD administrative interfaces include: + +- an NFSD or SUNRPC module parameter + +- export options in /etc/exports + +- files under /proc/fs/nfsd/ or /proc/sys/sunrpc/ + +- the NFSD netlink protocol + +Frequently, a request is made to introduce or modify one of NFSD's +traditional administrative interfaces. Certainly it is technically +easy to introduce a new administrative setting. However, there are +good reasons why the NFSD maintainers prefer to leave that as a last +resort: + +- As with any API, administrative interfaces are difficult to get + right. + +- Once they are documented and have a legacy of use, administrative + interfaces become difficult to modify or remove. + +- Every new administrative setting multiplies the NFSD test matrix. + +- The cost of one administrative interface is incremental, but costs + add up across all of the existing interfaces. + +It is often better for everyone if effort is made up front to +understanding the underlying requirement of the new setting, and +then trying to make it tune itself (or to become otherwise +unnecessary). + +If a new setting is indeed necessary, first consider adding it to +the NFSD netlink protocol. Or if it doesn't need to be a reliable +long term user space feature, it can be added to NFSD's menagerie of +experimental settings which reside under /sys/kernel/debug/nfsd/ . + +Field observability +~~~~~~~~~~~~~~~~~~~ +NFSD employs several different mechanisms for observing operation, +including counters, printks, WARNings, and static trace points. Each +have their strengths and weaknesses.

Contributors are encouraged to +use these tools without kdevops, or contributors should install and +use kdevops themselves to verify their patches before submission. + +Coding style +~~~~~~~~~~~~ +Follow the coding style preferences described in + + Documentation/process/coding-style.rst + +with the following exceptions: + +- Add new local variables to a function in reverse Christmas tree + order + +- Use the kdoc comment style for + + non-static functions + + static inline functions + + static functions that are callbacks/virtual functions + +- All new function names start with ``nfsd_`` for non-NFS-version- + specific functions. + +- New function names that are specific to NFSv2 or NFSv3, or are + used by all minor versions of NFSv4, use ``nfsdN_`` where N is + the version. + +- New function names specific to an NFSv4 minor version can be + named with ``nfsd4M_`` where M is the minor version. + +Patch preparation +~~~~~~~~~~~~~~~~~ +Read and follow all guidelines in + + Documentation/process/submitting-patches.rst + +Use tagging to identify all patch authors. However, reviewers and +testers should be added by replying to the email patch submission. +Email is extensively used in order to publicly archive review and +testing attributions. These tags are automatically inserted into +your patches when they are applied. + +The code in the body of the diff already shows /what/ is being +changed. Thus it is not necessary to repeat that in the patch +description. Instead, the description should contain one or more +of: + +- A brief problem statement ("what is this patch trying to fix?") + with a root-cause analysis. + +- End-user visible symptoms or items that a support engineer might + use to search for the patch, like stack traces. + +- A brief explanation of why the patch is the best way to address + the problem. + +- Any context that reviewers might need to understand the changes + made by the patch. + +- Any relevant benchmarking results, and/or functional test results. + +As detailed in Documentation/process/submitting-patches.rst, +identify the point in history that the issue being addressed was +introduced by using a Fixes: tag. + +Mention in the patch description if that point in history cannot be +determined -- that is, no Fixes: tag can be provided. In this case, +please make it clear to maintainers whether an LTS backport is +needed even though there is no Fixes: tag. + +The NFSD maintainers prefer to add stable tagging themselves, after +public discussion in response to the patch submission. Contributors +may suggest stable tagging, but be aware that many version +management tools add such stable Cc's when you post your patches. +Don't add "Cc: stable" unless you are absolutely sure the patch +needs to go to stable during the initial submission process. + +Patch submission +~~~~~~~~~~~~~~~~ +Patches to NFSD are submitted via the kernel's email-based review +process that is common to most other kernel subsystems. + +Just before each submission, rebase your patch or series on the +nfsd-testing branch at + + https://git.kernel.org/pub/scm/linux/kernel/git/cel/linux.git + +The NFSD subsystem is maintained separately from the Linux in-kernel +NFS client. The NFSD maintainers do not normally take submissions +for client changes, nor can they respond authoritatively to bug +reports or feature requests for NFS client code. + +This means that contributors might be asked to resubmit patches if +they were emailed to the incorrect set of maintainers and reviewers. +This is not a rejection, but simply a correction of the submission +process. + +When in doubt, consult the NFSD entry in the MAINTAINERS file to +see which files and directories fall under the NFSD subsystem. + +The proper set of email addresses for NFSD patches are: + +To: the NFSD maintainers and reviewers listed in MAINTAINERS +Cc: linux-nfs@vger.kernel.org and optionally linux-kernel@ + +If there are other subsystems involved in the patches (for example +MM or RDMA) their primary mailing list address can be included in +the Cc: field. Other contributors and interested parties may be +included there as well. + +In general we prefer that contributors use common patch email tools +such as "git send-email" or "stg email format/send", which tend to +get the details right without a lot of fuss. + +A series consisting of a single patch is not required to have a +cover letter. However, a cover letter can be included if there is +substantial context that is not appropriate to include in the +patch description. + +Please note that, with an e-mail based submission process, series +cover letters are not part of the work that is committed to the +kernel source code base or its commit history. Therefore always try +to keep pertinent information in the patch descriptions. + +Design documentation is welcome, but as cover letters are not +preserved, a perhaps better option is to include a patch that adds +such documentation under Documentation/filesystems/nfs/. + +Reviewers will ask about test coverage and what use cases the +patches are expected to address. Please be prepared to answer these +questions. + +Review comments from maintainers might be politely stated, but in +general, these are not optional to address when they are actionable. +If necessary, the maintainers retain the right to not apply patches +when contributors refuse to address reasonable requests. + +Post changes to kernel source code and user space source code as +separate series. You can connect the two series with comments in +your cover letters. + +Generally the NFSD maintainers ask for a reposts even for simple +modifications in order to publicly archive the request and the +resulting repost before it is pulled into the NFSD trees. This +also enables us to rebuild a patch series quickly without missing +changes that might have been discussed via email. + +Avoid frequently reposting large series with only small changes. As +a rule of thumb, posting substantial changes more than once a week +will result in reviewer overload. + +Remember, there are only a handful of subsystem maintainers and +reviewers, but potentially many sources of contributions. The +maintainers and reviewers, therefore, are always the less scalable +resource. Be kind to your friendly neighborhood maintainer. + +Patch Acceptance +~~~~~~~~~~~~~~~~ +There isn't a formal review process for NFSD, but we like to see +at least two Reviewed-by: notices for patches that are more than +simple clean-ups. Reviews are done in public on +linux-nfs@vger.kernel.org and are archived on lore.kernel.org. + +Currently the NFSD patch queues are maintained in branches here: + + https://git.kernel.org/pub/scm/linux/kernel/git/cel/linux.git + +The NFSD maintainers apply patches initially to the nfsd-testing +branch, which is always open to new submissions. Patches can be +applied while review is ongoing. nfsd-testing is a topic branch, +so it can change frequently, it will be rebased, and your patch +might get dropped if there is a problem with it. + +Generally a script-generated "thank you" email will indicate when +your patch has been added to the nfsd-testing branch. You can track +the progress of your patch using the linux-nfs patchworks instance: + + https://patchwork.kernel.org/project/linux-nfs/list/ + +While your patch is in nfsd-testing, it is exposed to a variety of +test environments, including community zero-day bots, static +analysis tools, and NFSD continuous integration testing. The soak +period is three to four weeks. + +Each patch that survives in nfsd-testing for the soak period without +changes is moved to the nfsd-next branch. + +The nfsd-next branch is automatically merged into linux-next and +fs-next on a nightly basis. + +Patches that survive in nfsd-next are included in the next NFSD +merge window pull request. These windows typically occur once every +63 days (nine weeks). + +When the upstream merge window closes, the nfsd-next branch is +renamed nfsd-fixes, and a new nfsd-next branch is created, based on +the upstream -rc1 tag. + +Fixes that are destined for an upstream -rc release also run the +nfsd-testing gauntlet, but are then applied to the nfsd-fixes +branch. That branch is made available for Linus to pull after a +short time. In order to limit the risk of introducing regressions, +we limit such fixes to emergency situations or fixes to breakage +that occurred during the most recent upstream merge. + +Please make it clear when submitting an emergency patch that +immediate action (either application to -rc or LTS backport) is +needed. + +Sensitive patch submissions and bug reports +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +CVEs are generated by specific members of the Linux kernel community +and several external entities. The Linux NFS community does not emit +or assign CVEs. CVEs are assigned after an issue and its fix are +known. + +However, the NFSD maintainers sometimes receive sensitive security +reports, and at times these are significant enough to need to be +embargoed. In such rare cases, fixes can be developed and reviewed +out of the public eye. + +Please be aware that many version management tools add the stable +Cc's when you post your patches. This is generally a nuisance, but +it can result in outing an embargoed security issue accidentally. +Don't add "Cc: stable" unless you are absolutely sure the patch +needs to go to stable@ during the initial submission process. + +Patches that are merged without ever appearing on any list, and +which carry a Reported-by: or Fixes: tag are detected as suspicious +by security-focused people. We encourage that, after any private +review, security-sensitive patches should be posted to linux-nfs@ +for the usual public review, archiving, and test period. + +LLM-generated submissions +~~~~~~~~~~~~~~~~~~~~~~~~~ +The Linux kernel community as a whole is still exploring the new +world of LLM-generated code. The NFSD maintainers will entertain +submission of patches that are partially or wholly generated by +LLM-based development tools. Such submissions are held to the +same standards as submissions created entirely by human authors: + +- The human contributor identifies themselves via a Signed-off-by: + tag. This tag counts as a DoC. + +- The human contributor is solely responsible for code provenance + and any contamination by inadvertently-included code with a + conflicting license, as usual. + +- The human contributor must be able to answer and address review + questions. A patch description such as "This fixed my problem + but I don't know why" is not acceptable. + +- The contribution is subjected to the same test regimen as all + other submissions. + +- An indication (via a Generated-by: tag or otherwise) that the + contribution is LLM-generated is not required. + +It is easy to address review comments and fix requests in LLM +generated code. So easy, in fact, that it becomes tempting to repost +refreshed code immediately. Please resist that temptation. + +As always, please avoid reposting series revisions more than once +every 24 hours. + +Clean-up patches +~~~~~~~~~~~~~~~~ +The NFSD maintainers discourage patches which perform simple clean- +ups, which are not in the context of other work. For example: + +* Addressing ``checkpatch.pl`` warnings after merge +* Addressing :ref:`Local variable ordering` issues +* Addressing long-standing whitespace damage + +This is because it is felt that the churn that such changes produce +comes at a greater cost than the value of such clean-ups. + +Conversely, spelling and grammar fixes are encouraged. + +Stable and LTS support +---------------------- +Upstream NFSD continuous integration testing runs against LTS trees +whenever they are updated. + +Please indicate when a patch containing a fix needs to be considered +for LTS kernels, either via a Fixes: tag or explicit mention. + +Feature requests +---------------- +There is no one way to make an official feature request, but +discussion about the request should eventually make its way to +the linux-nfs@vger.kernel.org mailing list for public review by +the community. + +Subsystem boundaries +~~~~~~~~~~~~~~~~~~~~ +NFSD itself is not much more than a protocol engine. This means its +primary responsibility is to translate the NFS protocol into API +calls in the Linux kernel. For example, NFSD is not responsible for +knowing exactly how bytes or file attributes are managed on a block +device. It relies on other kernel subsystems for that. + +If the subsystems on which NFSD relies do not implement a particular +feature, even if the standard NFS protocols do support that feature, +that usually means NFSD cannot provide that feature without +substantial development work in other areas of the kernel. + +Specificity +~~~~~~~~~~~ +Feature requests can come from anywhere, and thus can often be +nebulous. A requester might not understand what a "use case" or +"user story" is. These descriptive paradigms are often used by +developers and architects to understand what is required of a +design, but are terms of art in the software trade, not used in +the everyday world. + +In order to prevent contributors and maintainers from becoming +overwhelmed, we won't be afraid of saying "no" politely to +underspecified requests. + +Community roles and their authority +----------------------------------- +The purpose of Linux subsystem communities is to provide expertise +and active stewardship of a narrow set of source files in the Linux +kernel. This can include managing user space tooling as well. + +To contextualize the structure of the Linux NFS community that +is responsible for stewardship of the NFS server code base, we +define the community roles here. + +- **Contributor** : Anyone who submits a code change, bug fix, + recommendation, documentation fix, and so on. A contributor can + submit regularly or infrequently. + +- **Outside Contributor** : A contributor who is not a regular actor + in the Linux NFS community. This can mean someone who contributes + to other parts of the kernel, or someone who just noticed a + misspelling in a comment and sent a patch. + +- **Reviewer** : Someone who is named in the MAINTAINERS file as a + reviewer is an area expert who can request changes to contributed + code, and expects that contributors will address the request. + +- **External Reviewer** : Someone who is not named in the + MAINTAINERS file as a reviewer, but who is an area expert. + Examples include Linux kernel contributors with networking, + security, or persistent storage expertise, or developers who + contribute primarily to other NFS implementations. + +One or more people will take on the following roles. These people +are often generically referred to as "maintainers", and are +identified in the MAINTAINERS file with the "M:" tag under the NFSD +subsystem. + +- **Upstream Release Manager** : This role is responsible for + curating contributions into a branch, reviewing test results, and + then sending a pull request during merge windows. There is a + trust relationship between the release manager and Linus. + +- **Bug Triager** : Someone who is a first responder to bug reports + submitted to the linux-nfs mailing list or bug trackers, and helps + troubleshoot and identify next steps. + +- **Security Lead** : The security lead handles contacts from the + security community to resolve immediate issues, as well as dealing + with long-term security issues such as supply chain concerns. For + upstream, that's usually whether contributions violate licensing + or other intellectual property agreements. + +- **Testing Lead** : The testing lead builds and runs the test + infrastructure for the subsystem. The testing lead may ask for + patches to be dropped because of ongoing high defect rates. + +- **LTS Maintainer** : The LTS maintainer is responsible for managing + the Fixes: and Cc: stable annotations on patches, and seeing that + patches that cannot be automatically applied to LTS kernels get + proper manual backports as necessary. + +- **Community Manager** : This umpire role can be asked to call balls + and strikes during conflicts, but is also responsible for ensuring + the health of the relationships within the community and for + facilitating discussions on long-term topics such as how to manage + growing technical debt. diff --git a/Documentation/filesystems/porting.rst b/Documentation/filesystems/porting.rst index 7233b04668fc..3397937ed838 100644 --- a/Documentation/filesystems/porting.rst +++ b/Documentation/filesystems/porting.rst @@ -211,7 +211,7 @@ test and set for you. e.g.:: inode = iget_locked(sb, ino); - if (inode->i_state & I_NEW) { + if (inode_state_read_once(inode) & I_NEW) { err = read_inode_from_disk(inode); if (err < 0) { iget_failed(inode); @@ -1286,6 +1286,11 @@ The vm_area_desc provides the minimum required information for a filesystem to initialise state upon memory mapping of a file-backed region, and output parameters for the file system to set this state. +In nearly all cases, this is all that is required for a filesystem.

SPDX-License-Identifier: GPL-2.0 + +======================== +Linux Color Pipeline API +======================== + +What problem are we solving? +============================ + +We would like to support pre-, and post-blending complex color +transformations in display controller hardware in order to allow for +HW-supported HDR use-cases, as well as to provide support to +color-managed applications, such as video or image editors. + +It is possible to support an HDR output on HW supporting the Colorspace +and HDR Metadata drm_connector properties, but that requires the +compositor or application to render and compose the content into one +final buffer intended for display. Doing so is costly. + +Most modern display HW offers various 1D LUTs, 3D LUTs, matrices, and other +operations to support color transformations. These operations are often +implemented in fixed-function HW and therefore much more power efficient than +performing similar operations via shaders or CPU. + +We would like to make use of this HW functionality to support complex color +transformations with no, or minimal CPU or shader load. The switch between HW +fixed-function blocks and shaders/CPU must be seamless with no visible +difference when fallback to shaders/CPU is neceesary at any time. + + +How are other OSes solving this problem? +======================================== + +The most widely supported use-cases regard HDR content, whether video or +gaming. + +Most OSes will specify the source content format (color gamut, encoding transfer +function, and other metadata, such as max and average light levels) to a driver. +Drivers will then program their fixed-function HW accordingly to map from a +source content buffer's space to a display's space. + +When fixed-function HW is not available the compositor will assemble a shader to +ask the GPU to perform the transformation from the source content format to the +display's format. + +A compositor's mapping function and a driver's mapping function are usually +entirely separate concepts. On OSes where a HW vendor has no insight into +closed-source compositor code such a vendor will tune their color management +code to visually match the compositor's. On other OSes, where both mapping +functions are open to an implementer they will ensure both mappings match. + +This results in mapping algorithm lock-in, meaning that no-one alone can +experiment with or introduce new mapping algorithms and achieve +consistent results regardless of which implementation path is taken. + +Why is Linux different? +======================= + +Unlike other OSes, where there is one compositor for one or more drivers, on +Linux we have a many-to-many relationship. Many compositors; many drivers. +In addition each compositor vendor or community has their own view of how +color management should be done. This is what makes Linux so beautiful. + +This means that a HW vendor can now no longer tune their driver to one +compositor, as tuning it to one could make it look fairly different from +another compositor's color mapping. + +We need a better solution. + + +Descriptive API +=============== + +An API that describes the source and destination colorspaces is a descriptive +API. It describes the input and output color spaces but does not describe +how precisely they should be mapped. Such a mapping includes many minute +design decision that can greatly affect the look of the final result. + +It is not feasible to describe such mapping with enough detail to ensure the +same result from each implementation. In fact, these mappings are a very active +research area. + + +Prescriptive API +================ + +A prescriptive API describes not the source and destination colorspaces. It +instead prescribes a recipe for how to manipulate pixel values to arrive at the +desired outcome. + +This recipe is generally an ordered list of straight-forward operations, +with clear mathematical definitions, such as 1D LUTs, 3D LUTs, matrices, +or other operations that can be described in a precise manner. + + +The Color Pipeline API +====================== + +HW color management pipelines can significantly differ between HW +vendors in terms of availability, ordering, and capabilities of HW +blocks. This makes a common definition of color management blocks and +their ordering nigh impossible. Instead we are defining an API that +allows user space to discover the HW capabilities in a generic manner, +agnostic of specific drivers and hardware. + + +drm_colorop Object +================== + +To support the definition of color pipelines we define the DRM core +object type drm_colorop. Individual drm_colorop objects will be chained +via the NEXT property of a drm_colorop to constitute a color pipeline. +Each drm_colorop object is unique, i.e., even if multiple color +pipelines have the same operation they won't share the same drm_colorop +object to describe that operation. + +Note that drivers are not expected to map drm_colorop objects statically +to specific HW blocks. The mapping of drm_colorop objects is entirely a +driver-internal detail and can be as dynamic or static as a driver needs +it to be. See more in the Driver Implementation Guide section below. + +Each drm_colorop has three core properties: + +TYPE: An enumeration property, defining the type of transformation, such as +* enumerated curve +* custom (uniform) 1D LUT +* 3x3 matrix +* 3x4 matrix +* 3D LUT +* etc. + +Depending on the type of transformation other properties will describe +more details. + +BYPASS: A boolean property that can be used to easily put a block into +bypass mode. The BYPASS property is not mandatory for a colorop, as long +as the entire pipeline can get bypassed by setting the COLOR_PIPELINE on +a plane to '0'. + +NEXT: The ID of the next drm_colorop in a color pipeline, or 0 if this +drm_colorop is the last in the chain. + +An example of a drm_colorop object might look like one of these:: + + /* 1D enumerated curve */ + Color operation 42 + ├─ "TYPE": immutable enum {1D enumerated curve, 1D LUT, 3x3 matrix, 3x4 matrix, 3D LUT, etc.} = 1D enumerated curve + ├─ "BYPASS": bool {true, false} + ├─ "CURVE_1D_TYPE": enum {sRGB EOTF, sRGB inverse EOTF, PQ EOTF, PQ inverse EOTF, …} + └─ "NEXT": immutable color operation ID = 43 + + /* custom 4k entry 1D LUT */ + Color operation 52 + ├─ "TYPE": immutable enum {1D enumerated curve, 1D LUT, 3x3 matrix, 3x4 matrix, 3D LUT, etc.} = 1D LUT + ├─ "BYPASS": bool {true, false} + ├─ "SIZE": immutable range = 4096 + ├─ "DATA": blob + └─ "NEXT": immutable color operation ID = 0 + + /* 17^3 3D LUT */ + Color operation 72 + ├─ "TYPE": immutable enum {1D enumerated curve, 1D LUT, 3x3 matrix, 3x4 matrix, 3D LUT, etc.} = 3D LUT + ├─ "BYPASS": bool {true, false} + ├─ "SIZE": immutable range = 17 + ├─ "DATA": blob + └─ "NEXT": immutable color operation ID = 73 + +drm_colorop extensibility +------------------------- + +Unlike existing DRM core objects, like &drm_plane, drm_colorop is not +extensible. This simplifies implementations and keeps all functionality +for managing &drm_colorop objects in the DRM core. + +If there is a need one may introduce a simple &drm_colorop_funcs +function table in the future, for example to support an IN_FORMATS +property on a &drm_colorop. + +If a driver requires the ability to create a driver-specific colorop +object they will need to add &drm_colorop func table support with +support for the usual functions, like destroy, atomic_duplicate_state, +and atomic_destroy_state. + + +COLOR_PIPELINE Plane Property +============================= + +Color Pipelines are created by a driver and advertised via a new +COLOR_PIPELINE enum property on each plane. Values of the property +always include object id 0, which is the default and means all color +processing is disabled. Additional values will be the object IDs of the +first drm_colorop in a pipeline. A driver can create and advertise none, +one, or more possible color pipelines. A DRM client will select a color +pipeline by setting the COLOR PIPELINE to the respective value. + +NOTE: Many DRM clients will set enumeration properties via the string +value, often hard-coding it. Since this enumeration is generated based +on the colorop object IDs it is important to perform the Color Pipeline +Discovery, described below, instead of hard-coding color pipeline +assignment. Drivers might generate the enum strings dynamically. +Hard-coded strings might only work for specific drivers on a specific +pieces of HW. Color Pipeline Discovery can work universally, as long as +drivers implement the required color operations. + +The COLOR_PIPELINE property is only exposed when the +DRM_CLIENT_CAP_PLANE_COLOR_PIPELINE is set. Drivers shall ignore any +existing pre-blend color operations when this cap is set, such as +COLOR_RANGE and COLOR_ENCODING. If drivers want to support COLOR_RANGE +or COLOR_ENCODING functionality when the color pipeline client cap is +set, they are expected to expose colorops in the pipeline to allow for +the appropriate color transformation. + +Setting of the COLOR_PIPELINE plane property or drm_colorop properties +is only allowed for userspace that sets this client cap. + +An example of a COLOR_PIPELINE property on a plane might look like this:: + + Plane 10 + ├─ "TYPE": immutable enum {Overlay, Primary, Cursor} = Primary + ├─ … + └─ "COLOR_PIPELINE": enum {0, 42, 52} = 0 + + +Color Pipeline Discovery +======================== + +A DRM client wanting color management on a drm_plane will: + +1.

As noted above the +colorops can map to HW directly but don't need to do so. Here are some +suggestions on how to think about creating your color pipelines: + +- Try to expose pipelines that use already defined colorops, even if + your hardware pipeline is split differently. This allows existing + userspace to immediately take advantage of the hardware. + +- Additionally, try to expose your actual hardware blocks as colorops. + Define new colorop types where you believe it can offer significant + benefits if userspace learns to program them. + +- Avoid defining new colorops for compound operations with very narrow + scope. If you have a hardware block for a special operation that + cannot be split further, you can expose that as a new colorop type. + However, try to not define colorops for "use cases", especially if + they require you to combine multiple hardware blocks. + +- Design new colorops as prescriptive, not descriptive; by the + mathematical formula, not by the assumed input and output. + +A defined colorop type must be deterministic. The exact behavior of the +colorop must be documented entirely, whether via a mathematical formula +or some other description. Its operation can depend only on its +properties and input and nothing else, allowed error tolerance +notwithstanding. + + +Driver Forward/Backward Compatibility +===================================== + +As this is uAPI drivers can't regress color pipelines that have been +introduced for a given HW generation.

It should accept a DRM +format and a format modifier to resolve the color mode's ambiguity. As +framebuffers can be multi-planar, the new ioctl has to return the buffer size, +pitch and GEM handle for each individual color plane. + +In the first step, the new ioctl can be limited to the current features of +the existing DUMB_CREATE. Individual drivers can then be extended to support +multi-planar formats. Rockchip might require this and would be a good candidate. + +It might also be helpful to userspace to query information about the size of +a potential buffer, if allocated. Userspace would supply geometry and format; +the kernel would return minimal allocation sizes and scanline pitch. There is +interest to allocate that memory from another device and provide it to the +DRM driver (say via dma-buf). + +Another requested feature is the ability to allocate a buffer by size, without +format. Accelators use this for their buffer allocation and it could likely be +generalized. + +In addition to the kernel implementation, there must be user-space support +for the new ioctl.

It monitors bidirectional current into a +shunt resistor and load voltage up to 60 V in a synchronized way. Digital bus +interface is I2C/SMbus. The TSC1641 allows the assertion of several alerts +regarding the voltage, current, power and temperature. + +Usage Notes +----------- + +The TSC1641 driver requires the value of the external shunt resistor to +correctly compute current and power measurements. The resistor value, in +micro-ohms, should be provided either through the device tree property +"shunt-resistor-micro-ohms" or via writable sysfs attribute "shunt_resistor". +Please refer to the Documentation/devicetree/bindings/hwmon/st,tsc1641.yaml +for bindings if the device tree is used. + +Supported range of shunt resistor values is from 100 uOhm to 655.35 mOhm, in +10 uOhm steps. +When selecting the value keep in mind device maximum DC power measurement is +1600W. See datasheet p.22 for ST recommendations on selecting shunt value. + +If the shunt resistor value is not specified in the device tree, the driver +initializes it to 1000 uOhm by default. Users may configure the correct shunt +resistor value at runtime by writing to the "shunt_resistor" sysfs attribute. + +The driver only supports continuous operating mode. +Measurement ranges: + +================ =============================================================== +Current Bidirectional, dependent on shunt +Bus voltage 0-60V +Maximum DC power 1600W +Temperature -40C to +125C +================ =============================================================== + +Sysfs entries +------------- + +==================== =========================================================== +in0_input bus voltage (mV) +in0_max bus voltage max alarm limit (mV) +in0_max_alarm bus voltage max alarm limit exceeded +in0_min bus voltage min alarm limit (mV) +in0_min_alarm bus voltage min alarm limit exceeded + +curr1_input current measurement (mA) +curr1_max current max alarm limit (mA) +curr1_max_alarm current max alarm limit exceeded +curr1_min current min alarm limit (mA) +curr1_min_alarm current min alarm limit exceeded + +power1_input power measurement (uW) +power1_max power max alarm limit (uW) +power1_max_alarm power max alarm limit exceeded + +shunt_resistor shunt resistor value (uOhms) + +temp1_input temperature measurement (mdegC) +temp1_max temperature max alarm limit (mdegC) +temp1_max_alarm temperature max alarm limit exceeded + +update_interval data conversion time (1 - 33ms), longer conversion time + corresponds to higher effective resolution in bits +==================== =========================================================== \ No newline at end of file diff --git a/Documentation/hwmon/zl6100.rst b/Documentation/hwmon/zl6100.rst index d42ed9d3ac69..1513c9d2d461 100644 --- a/Documentation/hwmon/zl6100.rst +++ b/Documentation/hwmon/zl6100.rst @@ -9,7 +9,7 @@ Supported chips: Addresses scanned: - - Datasheet: https://www.renesas.com/us/en/document/dst/zl2004-datasheet.pdf + Datasheet: https://www.renesas.com/us/en/document/dst/zl2004-datasheet * Renesas / Intersil / Zilker Labs ZL2005 @@ -17,7 +17,7 @@ Supported chips: Addresses scanned: - - Datasheet: https://www.renesas.com/us/en/document/dst/zl2005-datasheet.pdf + Datasheet: https://www.renesas.com/us/en/document/dst/zl2005-datasheet * Renesas / Intersil / Zilker Labs ZL2006 @@ -25,7 +25,7 @@ Supported chips: Addresses scanned: - - Datasheet: https://www.renesas.com/us/en/document/dst/zl2006-datasheet.pdf + Datasheet: https://www.renesas.com/us/en/document/dst/zl2006-datasheet * Renesas / Intersil / Zilker Labs ZL2008 @@ -33,7 +33,7 @@ Supported chips: Addresses scanned: - - Datasheet: https://www.renesas.com/us/en/document/dst/zl2008-datasheet.pdf + Datasheet: https://www.renesas.com/us/en/document/dst/zl2008-datasheet * Renesas / Intersil / Zilker Labs ZL2105 @@ -41,7 +41,7 @@ Supported chips: Addresses scanned: - - Datasheet: https://www.renesas.com/us/en/document/dst/zl2105-datasheet.pdf + Datasheet: https://www.renesas.com/us/en/document/dst/zl2105-datasheet * Renesas / Intersil / Zilker Labs ZL2106 @@ -49,7 +49,7 @@ Supported chips: Addresses scanned: - - Datasheet: https://www.renesas.com/us/en/document/dst/zl2106-datasheet.pdf + Datasheet: https://www.renesas.com/us/en/document/dst/zl2106-datasheet * Renesas / Intersil / Zilker Labs ZL6100 @@ -57,7 +57,7 @@ Supported chips: Addresses scanned: - - Datasheet: https://www.renesas.com/us/en/document/dst/zl6100-datasheet.pdf + Datasheet: https://www.renesas.com/us/en/document/dst/zl6100-datasheet * Renesas / Intersil / Zilker Labs ZL6105 @@ -65,7 +65,7 @@ Supported chips: Addresses scanned: - - Datasheet: https://www.renesas.com/us/en/document/dst/zl6105-datasheet.pdf + Datasheet: https://www.renesas.com/us/en/document/dst/zl6105-datasheet * Renesas / Intersil / Zilker Labs ZL8802 diff --git a/Documentation/i2c/busses/i2c-i801.rst b/Documentation/i2c/busses/i2c-i801.rst index 36c563ad3f06..c939a5bfc8d0 100644 --- a/Documentation/i2c/busses/i2c-i801.rst +++ b/Documentation/i2c/busses/i2c-i801.rst @@ -51,6 +51,7 @@ Supported adapters: * Intel Arrow Lake (SOC) * Intel Panther Lake (SOC) * Intel Wildcat Lake (SOC) + * Intel Diamond Rapids (SOC) Datasheets: Publicly available at the Intel website diff --git a/Documentation/iio/ade9000.rst b/Documentation/iio/ade9000.rst index 43d4b8dc1cb7..c9ff702a4251 100644 --- a/Documentation/iio/ade9000.rst +++ b/Documentation/iio/ade9000.rst @@ -264,5 +264,5 @@ Configure RMS voltage event thresholds (requires interrupts): 8.

MTD 设备代表闪存设备，由较大尺寸的擦除块组成，通常约 128KiB。块设备由 + 小块组成，通常 512 字节。 +2. MTD 设备支持 3 种主要操作：在擦除块内偏移位置读取、在擦除块内偏移位置写 + 入、以及擦除整个擦除块。块设备支持 2 种主要操作：读取整个块和写入整个块。 +3. 整个擦除块必须先擦除才能重写内容。块可直接重写。 +4. 擦除块在经历一定次数的擦写周期后会磨损，通常 SLC NAND 和 NOR 闪存为 + 100K-1G 次，MLC NAND 闪存为 1K-10K 次。块设备不具备磨损特性。 +5. 擦除块可能损坏（仅限 NAND 闪存），软件需处理此问题。硬盘上的块通常不会损 + 坏，因为硬件有坏块替换机制（至少现代 LBA 硬盘如此）。 + +这充分说明了 UBIFS 与传统文件系统的本质差异。 + +UBIFS 工作在 UBI 层之上。UBI 是一个独立的软件层（位于 drivers/mtd/ubi）， +本质上是卷管理和磨损均衡层。它提供称为 UBI 卷的高级抽象，比 MTD 设备更上层。 +UBI 设备的编程模型与 MTD 设备非常相似，仍由大容量擦除块组成，支持读/写/擦 +除操作，但 UBI 设备消除了磨损和坏块限制（上述列表的第 4 和第 5 项）。 + +某种意义上，UBIFS 是 JFFS2 文件系统的下一代产品，但它与 JFFS2 差异巨大且 +不兼容。主要区别如下： + +* JFFS2 工作在 MTD 设备之上，UBIFS 依赖于 UBI 并工作在 UBI 卷之上。 +* JFFS2 没有介质索引，需在挂载时构建索引，这要求全介质扫描。UBIFS 在闪存 + 介质上维护文件系统索引信息，无需全介质扫描，因此挂载速度远快于 JFFS2。 +* JFFS2 是直写（write-through）文件系统，而 UBIFS 支持回写 + （write-back），这使得 UBIFS 写入速度快得多。 + +与 JFFS2 类似，UBIFS 支持实时压缩，可将大量数据存入闪存。 + +与 JFFS2 类似，UBIFS 能容忍异常重启和断电。它不需要类似 fsck.ext2 的工 +具。UBIFS 会自动重放日志并从崩溃中恢复，确保闪存数据结构的一致性。 + +UBIFS 具有对数级扩展性（其使用的数据结构多为树形），因此挂载时间和内存消耗不 +像 JFFS2 那样线性依赖于闪存容量。这是因为 UBIFS 在闪存介质上维护文件系统 +索引。但 UBIFS 依赖于线性扩展的 UBI 层，因此整体 UBI/UBIFS 栈仍是线性扩 +展。尽管如此，UBIFS/UBI 的扩展性仍显著优于 JFFS2。 + +UBIFS 开发者认为，未来可开发同样具备对数级扩展性的 UBI2。UBI2 将支持与 +UBI 相同的 API，但二进制不兼容。因此 UBIFS 无需修改即可使用 UBI2。 + +挂载选项 +======== + +(*) 表示默认选项。 + +==================== ======================================================= +bulk_read 批量读取以利用闪存介质的顺序读取加速特性 +no_bulk_read (*) 禁用批量读取 +no_chk_data_crc (*) 跳过数据节点的 CRC 校验以提高读取性能。 仅在闪存 + 介质高度可靠时使用此选项。 此选项可能导致文件内容损坏无法被 + 察觉。 +chk_data_crc 强制校验数据节点的 CRC +compr=none 覆盖默认压缩器，设置为"none" +compr=lzo 覆盖默认压缩器，设置为"LZO" +compr=zlib 覆盖默认压缩器，设置为"zlib" +auth_key= 指定用于文件系统身份验证的密钥。 + 使用此选项将强制启用身份验证。 + 传入的密钥必须存在于内核密钥环中， 且类型必须是'logon' +auth_hash_name= 用于身份验证的哈希算法。同时用于哈希计算和 HMAC + 生成。典型值包括"sha256"或"sha512" +==================== ======================================================= + +快速使用指南 +============ + +挂载的 UBI 卷通过 "ubiX_Y" 或 "ubiX:NAME" 语法指定，其中 "X" 是 UBI +设备编号，"Y" 是 UBI 卷编号，"NAME" 是 UBI 卷名称。 + +将 UBI 设备 0 的卷 0 挂载到 /mnt/ubifs:: + + $ mount -t ubifs ubi0_0 /mnt/ubifs + +将 UBI 设备 0 的 "rootfs" 卷挂载到 /mnt/ubifs（"rootfs" 是卷名）:: + + $ mount -t ubifs ubi0:rootfs /mnt/ubifs + +以下是内核启动参数的示例，用于将 mtd0 附加到 UBI 并挂载 "rootfs" 卷： +ubi.mtd=0 root=ubi0:rootfs rootfstype=ubifs + +参考资料 +======== + +UBIFS 文档及常见问题解答/操作指南请访问 MTD 官网： + +- http://www.linux-mtd.infradead.org/doc/ubifs.html +- http://www.linux-mtd.infradead.org/faq/ubifs.html diff --git a/Documentation/translations/zh_CN/how-to.rst b/Documentation/translations/zh_CN/how-to.rst index ddd99c0f9b4d..7ae5d8765888 100644 --- a/Documentation/translations/zh_CN/how-to.rst +++ b/Documentation/translations/zh_CN/how-to.rst @@ -64,7 +64,7 @@ Linux 发行版和简单地使用 Linux 命令行，那么可以迅速开始了 :: cd linux -

+ +任何 TX 时间戳逻辑，无论是普通的 MAC 驱动程序、DSA 交换机驱动程序、PHY 驱动程 +序还是 MII 总线嗅探设备驱动程序，都应该设置此标志。但一个未意识到 PHC 堆叠的 +MAC 驱动程序可能会被其他不是它自己的实体设置此标志，并传递一个重复的时间戳。例 +如，典型的 TX 时间戳逻辑可能是将传输部分分为 2 个部分： + +1. "TX"：检查是否通过 ``.ndo_eth_ioctl``（"``priv->hwtstamp_tx_enabled + == true``"）和当前 skb 是否需要 TX 时间戳（"``skb_shinfo(skb)->tx_flags + & SKBTX_HW_TSTAMP``"）。如果为真，则设置 "``skb_shinfo(skb)->tx_flags + |= SKBTX_IN_PROGRESS``" 标志。注意：如上所述，在堆叠 PHC 系统中，此条件 + 不应触发，因为此 MAC 肯定不是最外层的 PHC。但这是典型的错误所在。传输继续 + 使用此数据包。 + +2. "TX 确认"：传输完成。驱动程序检查是否需要收集任何 TX 时间戳。这里通常是典 + 型的错误所在：驱动程序采取捷径，只检查 "``skb_shinfo(skb)->tx_flags & + SKBTX_IN_PROGRESS``" 是否设置。在堆叠 PHC 系统中，这是错误的，因为此 MAC + 驱动程序不是唯一在 TX 数据路径中启用 SKBTX_IN_PROGRESS 的实体。 + +此问题的正确解决方案是 MAC 驱动程序在其 "TX 确认" 部分中有一个复合检查，不仅 +针对 "``skb_shinfo(skb)->tx_flags & SKBTX_IN_PROGRESS``"，还针对 +"``priv->hwtstamp_tx_enabled == true``"。因为系统确保 PTP 时间戳仅对最 +外层 PHC 启用，此增强检查将避免向用户空间传递重复的 TX 时间戳。 diff --git a/Documentation/translations/zh_CN/rust/general-information.rst b/Documentation/translations/zh_CN/rust/general-information.rst index 251f6ee2bb44..9b5e37e13f38 100644 --- a/Documentation/translations/zh_CN/rust/general-information.rst +++ b/Documentation/translations/zh_CN/rust/general-information.rst @@ -13,6 +13,7 @@ 本文档包含了在内核中使用Rust支持时需要了解的有用信息。 +.. _rust_code_documentation_zh_cn: 代码文档 -------- diff --git a/Documentation/translations/zh_CN/rust/index.rst b/Documentation/translations/zh_CN/rust/index.rst index b01f887e7167..5347d4729588 100644 --- a/Documentation/translations/zh_CN/rust/index.rst +++ b/Documentation/translations/zh_CN/rust/index.rst @@ -10,7 +10,35 @@ Rust ==== -与内核中的Rust有关的文档。若要开始在内核中使用Rust，请阅读quick-start.rst指南。 +与内核中的Rust有关的文档。若要开始在内核中使用Rust，请阅读 quick-start.rst 指南。 + +Rust 实验 +--------- +Rust 支持在 v6.1 版本中合并到主线，以帮助确定 Rust 作为一种语言是否适合内核， +即是否值得进行权衡。 + +目前，Rust 支持主要面向对 Rust 支持感兴趣的内核开发人员和维护者， +以便他们可以开始处理抽象和驱动程序，并帮助开发基础设施和工具。 + +如果您是终端用户，请注意，目前没有适合或旨在生产使用的内置驱动程序或模块， +并且 Rust 支持仍处于开发/实验阶段，尤其是对于特定内核配置。 + +代码文档 +-------- + +给定一个内核配置，内核可能会生成 Rust 代码文档，即由 ``rustdoc`` 工具呈现的 HTML。 + +.. only:: rustdoc and html + + 该内核文档使用 `Rust 代码文档 `_ 构建。 + +.. only:: not rustdoc and html + + 该内核文档不使用 Rust 代码文档构建。 + +预生成版本提供在：https://rust.docs.kernel.org。 + +请参阅 :ref:`代码文档 ` 部分以获取更多详细信息。 .. toctree:: :maxdepth: 1 @@ -19,6 +47,9 @@ Rust general-information coding-guidelines arch-support + testing + +你还可以在 :doc:`../../../process/kernel-docs` 中找到 Rust 的学习材料。 .. only:: subproject and html diff --git a/Documentation/translations/zh_CN/rust/testing.rst b/Documentation/translations/zh_CN/rust/testing.rst new file mode 100644 index 000000000000..ca81f1cef6eb --- /dev/null +++ b/Documentation/translations/zh_CN/rust/testing.rst @@ -0,0 +1,215 @@ +..

SCSI命令在中间层及错误处理中的传递流程 +========================================= + +1.1 scsi_cmnd结构体 +------------------- + +每个SCSI命令都由struct scsi_cmnd（简称scmd）结构体 +表示。scmd包含两个list_head类型的链表节点：scmd->list +与scmd->eh_entry。其中scmd->list是用于空闲链表或设备 +专属的scmd分配链表，与错误处理讨论关联不大。而 +scmd->eh_entry则是专用于命令完成和错误处理链表，除非 +特别说明，本文讨论中所有scmd的链表操作均通过 +scmd->eh_entry实现。 + + +1.2 scmd是如何完成的？ +---------------------- + +底层设备驱动（LLDD）在获取SCSI命令（scmd）后，存在两种 +完成路径：底层驱动可通过调用hostt->queuecommand()时从 +中间层传递的scsi_done回调函数主动完成命令，或者当命令未 +及时完成时由块层（block layer）触发超时处理机制。 + + +1.2.1 通过scsi_done回调完成SCSI命令 +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +对于所有非错误处理（EH）命令，scsi_done()是其完成回调 +函数。它只调用blk_mq_complete_request()来删除块层的 +定时器并触发块设备软中断（BLOCK_SOFTIRQ）。 + +BLOCK_SOFTIRQ会间接调用scsi_complete()，进而调用 +scsi_decide_disposition()来决定如何处理该命令。 +scsi_decide_disposition()会查看scmd->result值和感 +应码数据来决定如何处理命令。 + + - SUCCESS + + 调用scsi_finish_command()来处理该命令。该函数会 + 执行一些维护操作，然后调用scsi_io_completion()来 + 完成I/O操作。scsi_io_completion()会通过调用 + blk_end_request及其相关函数来通知块层该请求已完成， + 如果发生错误，还会判断如何处理剩余的数据。 + + - NEEDS_RETRY + + - ADD_TO_MLQUEUE + + scmd被重新加入到块设备队列中。 + + - otherwise + + 调用scsi_eh_scmd_add(scmd)来处理该命令。 + 关于此函数的详细信息，请参见 [1-3]。 + + +1.2.2 scmd超时完成机制 +^^^^^^^^^^^^^^^^^^^^^^ + +SCSI命令超时处理机制由scsi_timeout()函数实现。 +当发生超时事件时，该函数 + + 1. 首先调用可选的hostt->eh_timed_out()回调函数。 + 返回值可能是以下3种情况之一： + + - ``SCSI_EH_RESET_TIMER`` + 表示需要延长命令执行时间并重启计时器。 + + - ``SCSI_EH_NOT_HANDLED`` + 表示eh_timed_out()未处理该命令。 + 此时将执行第2步的处理流程。 + + - ``SCSI_EH_DONE`` + 表示eh_timed_out()已完成该命令。 + + 2. 若未通过回调函数解决，系统将调用 + scsi_abort_command()发起异步中止操作，该操作最多 + 可执行scmd->allowed + 1次。但存在三种例外情况会跳 + 过异步中止而直接进入第3步处理：当检测到 + SCSI_EH_ABORT_SCHEDULED标志位已置位（表明该命令先 + 前已被中止过一次且当前重试仍失败）、当重试次数已达上 + 限、或当错误处理时限已到期时。在这些情况下，系统将跳 + 过异步中止流程而直接执行第3步处理方案。 + + 3. 最终未解决的命令会通过scsi_eh_scmd_add(scmd)移交给 + 错误处理子系统，具体流程详见[1-4]章节说明。 + +1.3 异步命令中止机制 +-------------------- + +当命令超时触发后，系统会通过scsi_abort_command()调度异 +步中止操作。若中止操作执行成功，则根据重试次数决定后续处 +理：若未达最大重试限制，命令将重新下发执行；若重试次数已 +耗尽，则命令最终以DID_TIME_OUT状态终止。当中止操作失败 +时，系统会调用scsi_eh_scmd_add()将该命令移交错误处理子 +系统，具体处理流程详见[1-4]。 + +1.4 错误处理(EH)接管机制 +------------------------ + +SCSI命令通过scsi_eh_scmd_add()函数进入错误处理流程，该函 +数执行以下操作： + + 1. 将scmd->eh_entry链接到shost->eh_cmd_q + + 2. 在shost->shost_state中设置SHOST_RECOVERY状态位 + + 3. 递增shost->host_failed失败计数器 + + 4. 当检测到shost->host_busy == shost->host_failed + 时（即所有进行中命令均已失败）立即唤醒SCSI错误处理 + 线程。 + +如上所述，当任一scmd被加入到shost->eh_cmd_q队列时，系统 +会立即置位shost_state中的SHOST_RECOVERY状态标志位，该操 +作将阻止块层向对应主机控制器下发任何新的SCSI命令。在此状 +态下，主机控制器上所有正在处理的scmd最终会进入以下三种状 +态之一：正常完成、失败后被移入到eh_cmd_q队列、或因超时被 +添加到shost->eh_cmd_q队列。 + +如果所有的SCSI命令都已经完成或失败，系统中正在执行的命令 +数量与失败命令数量相等（ +即shost->host_busy == shost->host_failed），此时将唤 +醒SCSI错误处理线程。SCSI错误处理线程一旦被唤醒，就可以确 +保所有未完成命令均已标记为失败状态，并且已经被链接到 +shost->eh_cmd_q队列中。 + +需要特别说明的是，这并不意味着底层处理流程完全静止。当底层 +驱动以错误状态完成某个scmd时，底层驱动及其下层组件会立刻遗 +忘该命令的所有关联状态。但对于超时命令，除非 +hostt->eh_timed_out()回调函数已经明确通知底层驱动丢弃该 +命令（当前所有底层驱动均未实现此功能），否则从底层驱动视角 +看该命令仍处于活跃状态，理论上仍可能在某时刻完成。当然，由 +于超时计时器早已触发，所有此类延迟完成都将被系统直接忽略。 + +我们将在后续章节详细讨论关于SCSI错误处理如何执行中止操作（ +即强制底层驱动丢弃已超时SCSI命令）。 + + +2. SCSI错误处理机制详解 +======================= + +SCSI底层驱动可以通过以下两种方式之一来实现SCSI错误处理。 + + - 细粒度的错误处理回调机制 + 底层驱动可选择实现细粒度的错误处理回调函数，由SCSI中间层 + 主导错误恢复流程并自动调用对应的回调函数。此实现模式的详 + 细设计规范在[2-1]节中展开讨论。 + + - eh_strategy_handler()回调函数 + 该回调函数作为统一的错误处理入口，需要完整实现所有的恢复 + 操作。具体而言，它必须涵盖SCSI中间层在常规恢复过程中执行 + 的全部处理流程，相关实现将在[2-2]节中详细描述。 + +当错误恢复流程完成后，SCSI错误处理系统通过调用 +scsi_restart_operations()函数恢复正常运行，该函数按顺序执行 +以下操作： + + 1. 验证是否需要执行驱动器安全门锁定机制 + + 2. 清除shost_state中的SHOST_RECOVERY状态标志位 + + 3. 唤醒所有在shost->host_wait上等待的任务。如果有人调用了 + scsi_block_when_processing_errors()则会发生这种情况。 + （疑问：由于错误处理期间块层队列已被阻塞，为何仍需显式 + 唤醒？） + + 4. 强制激活该主机控制器下所有设备的I/O队列 + + +2.1 基于细粒度回调的错误处理机制 +-------------------------------- + +2.1.1 概述 +^^^^^^^^^^^ + +如果不存在eh_strategy_handler()，SCSI中间层将负责驱动的 +错误处理。错误处理（EH）的目标有两个：一是让底层驱动程序、 +主机和设备不再维护已超时的SCSI命令（scmd）；二是使他们准备 +好接收新命令。当一个SCSI命令（scmd）被底层遗忘且底层已准备 +好再次处理或拒绝该命令时，即可认为该scmd已恢复。 + +为实现这些目标，错误处理（EH）会逐步执行严重性递增的恢复 +操作。部分操作通过下发SCSI命令完成，而其他操作则通过调用 +以下细粒度的错误处理回调函数实现。这些回调函数可以省略， +若被省略则默认始终视为执行失败。 + +:: + + int (* eh_abort_handler)(struct scsi_cmnd *); + int (* eh_device_reset_handler)(struct scsi_cmnd *); + int (* eh_bus_reset_handler)(struct scsi_cmnd *); + int (* eh_host_reset_handler)(struct scsi_cmnd *); + +只有在低级别的错误恢复操作无法恢复部分失败的SCSI命令 +（scmd）时，才会采取更高级别的恢复操作。如果最高级别的错误 +处理失败，就意味着整个错误恢复（EH）过程失败，所有未能恢复 +的设备被强制下线。 + +在恢复过程中，需遵循以下规则： + + - 错误恢复操作针对待处理列表eh_work_q中的失败的scmds执 + 行。如果某个恢复操作成功恢复了一个scmd，那么该scmd会 + 从eh_work_q链表中移除。 + + 需要注意的是，对某个scmd执行的单个恢复操作可能会恢复 + 多个scmd。例如，对某个设备执行复位操作可能会恢复该设 + 备上所有失败的scmd。 + + - 仅当低级别的恢复操作完成且eh_work_q仍然非空时，才会 + 触发更高级别的操作 + + - SCSI错误恢复机制会重用失败的scmd来发送恢复命令。对于 + 超时的scmd，SCSI错误处理机制会确保底层驱动在重用scmd + 前已不再维护该命令。 + +当一个SCSI命令（scmd）被成功恢复后，错误处理逻辑会通过 +scsi_eh_finish_cmd()将其从待处理队列（eh_work_q）移 +至错误处理的本地完成队列（eh_done_q）。当所有scmd均恢 +复完成（即eh_work_q为空时），错误处理逻辑会调用 +scsi_eh_flush_done_q()对这些已恢复的scmd进行处理，即 +重新尝试或错误总终止（向上层通知失败）。 + +SCSI命令仅在满足以下全部条件时才会被重试：对应的SCSI设 +备仍处于在线状态，未设置REQ_FAILFAST标志或递增后的 +scmd->retries值仍小于scmd->allowed。 + +2.1.2 SCSI命令在错误处理过程中的流转路径 +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + + 1. 错误完成/超时 + + :处理: 调用scsi_eh_scmd_add()处理scmd + + - 将scmd添加到shost->eh_cmd_q + - 设置SHOST_RECOVERY标记位 + - shost->host_failed++ + + :锁要求: shost->host_lock + + 2. 启动错误处理（EH） + + :操作: 将所有scmd移动到EH本地eh_work_q队列，并 + 清空 shost->eh_cmd_q。 + + :锁要求: shost->host_lock（非严格必需，仅为保持一致性） + + 3. scmd恢复 + + :操作: 调用scsi_eh_finish_cmd()完成scmd的EH + + - 将scmd从本地eh_work_q队列移至本地eh_done_q队列 + + :锁要求: 无 + + :并发控制: 每个独立的eh_work_q至多一个线程，确保无锁 + 队列的访问 + + 4.

底层驱动接口 +========================= + +简介 +==== +本文档概述了Linux SCSI中间层与SCSI底层驱动之间的接口。底层 +驱动（LLD）通常被称为主机总线适配器（HBA）驱动或主机驱动 +（HD）。在该上下文中，“主机”指的是计算机IO总线（例如：PCI总 +线或ISA总线）与SCSI传输层中单个SCSI启动器端口之间的桥梁。 +“启动器”端口（SCSI术语，参考SAM-3：http://www.t10.org）向 +“目标”SCSI端口（例如：磁盘）发送SCSI命令。在一个运行的系统 +中存在多种底层驱动（LLDs），但每种硬件类型仅对应一种底层驱动 +（LLD）。大多数底层驱动可以控制一个或多个SCSI HBA。部分HBA +内部集成多个主机控制器。 + +在某些情况下，SCSI传输层本身是已存在于Linux中的外部总线子系 +统（例如：USB和ieee1394）。在此类场景下，SCSI子系统的底层驱 +动将作为与其他驱动子系统的软件桥接层。典型示例包括 +usb-storage驱动（位于drivers/usb/storage目录）以 +及ieee1394/sbp2驱动（位于 drivers/ieee1394 目录）。 + +例如，aic7xxx底层驱动负责控制基于Adaptec公司7xxx芯片系列的 +SCSI并行接口（SPI）控制器。aic7xxx底层驱动可以内建到内核中 +或作为模块加载。一个Linux系统中只能运行一个aic7xxx底层驱动 +程序，但他可能控制多个主机总线适配器（HBA）。这些HBA可能位于 +PCI扩展卡或内置于主板中（或两者兼有）。某些基于aic7xxx的HBA +采用双控制器设计，因此会呈现为两个SCSI主机适配器。与大多数现 +代HBA相同，每个aic7xxx控制器都拥有其独立的PCI设备地址。[SCSI +主机与PCI设备之间一一对应虽然常见，但并非强制要求（例如ISA适 +配器就不适用此规则）。] + +SCSI中间层将SCSI底层驱动（LLD）与其他层（例如SCSI上层驱动以 +及块层）隔离开来。 + +本文档的版本大致与Linux内核2.6.8相匹配。 + +文档 +==== +内核源码树中设有专用的SCSI文档目录，通常位于 +Documentation/scsi目录下。大多数文档采用 +reStructuredText格式。本文档名为 +scsi_mid_low_api.rst，可在该目录中找到。该文档的最新版本可 +以访问 https://docs.kernel.org/scsi/scsi_mid_low_api.html +查阅。许多底层驱动（LLD）的文档也位于Documentation/scsi目录 +下（例如aic7xxx.rst）。SCSI中间层的简要说明见scsi.rst文件， +该文档包含指向Linux Kernel 2.4系列SCSI子系统的文档链接。此 +外还收录了两份SCSI上层驱动文档：st.rst（SCSI磁带驱动）与 +scsi-generic.rst（用通用SCSI（sg）驱动）。 + +部分底层驱动的文档（或相关URL）可能嵌在C源代码文件或与其 +源码同位于同一目录下。例如，USB大容量存储驱动的文档链接可以在 +目录/usr/src/linux/drivers/usb/storage下找到。 + +驱动程序结构 +============ +传统上，SCSI子系统的底层驱动（LLD）至少包含drivers/scsi +目录下的两个文件。例如，一个名为“xyz”的驱动会包含一个头文件 +xyz.h和一个源文件xyz.c。[实际上所有代码完全可以合并为单个 +文件，头文件并非必需的。] 部分需要跨操作系统移植的底层驱动会 +采用更复杂的文件结构。例如，aic7xxx驱动，就为通用代码与操作 +系统专用代码（如FreeBSD和Linux）分别创建了独立的文件。此类 +驱动通常会在drivers/scsi目录下拥有自己单独的子目录。 + +当需要向Linux内核添加新的底层驱动（LLD）时，必须留意 +drivers/scsi目录下的两个文件：Makefile以及Kconfig。建议参 +考现有底层驱动的代码组织方式。 + +随着Linux内核2.5开发内核逐步演进为2.6系列的生产版本，该接口 +也引入了一些变化。以驱动初始化代码为例，现有两种模型可用。其 +中旧模型与Linux内核2.4的实现相似，他基于在加载HBA驱动时检测 +到的主机，被称为“被动（passive）”初始化模型。而新的模型允许 +在底层驱动（LLD）的生命周期内动态拔插HBA，这种方式被称为“热 +插拔（hotplug）”初始化模型。推荐使用新的模型，因为他既能处理 +传统的永久连接SCSI设备，也能处理现代支持热插拔的类SCSI设备 +（例如通过USB或IEEE 1394连接的数码相机）。这两种初始化模型将 +在后续的章节中分别讨论。 + +SCSI底层驱动（LLD）通过以下3种方式与SCSI子系统进行交互： + + a) 直接调用由SCSI中间层提供的接口函数 + b) 将一组函数指针传递给中间层提供的注册函数，中间层将在 + 后续运行的某个时刻调用这些函数。这些函数由LLD实现。 + c) 直接访问中间层维护的核心数据结构 + +a）组中所涉及的所有函数，均列于下文“中间层提供的函数”章节中。 + +b）组中涉及的所有函数均列于下文名为“接口函数”的章节中。这些 +函数指针位于结构体struct scsi_host_template中，该结构体实 +例会被传递给scsi_host_alloc()。对于LLD未实现的接口函数，应 +对struct scsi_host_template中的对应成员赋NULL。如果在文件 +作用域定义一个struct scsi_host_template的实例，没有显式初 +始化的函数指针成员将自动设置为NULL。 + +c）组中提到的用法在“热插拔”环境中尤其需要谨慎处理。LLD必须 +明确知晓这些与中间层及其他层级共享的数据结构的生命周期。 + +LLD中定义的所有函数以及在文件作用域内定义的所有数据都应声明 +为static。例如，在一个名为“xxx”的LLD中的sdev_init()函数定 +义如下： +``static int xxx_sdev_init(struct scsi_device * sdev) { /* code */ }`` + +热插拔初始化模型 +================ +在该模型中，底层驱动（LLD）控制SCSI主机适配器在子系统中的注 +册与注销时机。主机最早可以在驱动初始化阶段被注册，最晚可以在 +驱动卸载时被移除。通常，驱动会响应来自sysfs probe()的回调， +表示已检测到一个主机总线适配器（HBA）。在确认该新设备是LLD的 +目标设备后，LLD初始化HBA，并将一个新的SCSI主机适配器注册到 +SCSI中间层。 + +在LLD初始化过程中，驱动应当向其期望发现HBA的IO总线（例如PCI +总线）进行注册。该操作通常可以通过sysfs完成。任何驱动参数（ +特别是那些在驱动加载后仍可修改的参数）也可以在此时通过sysfs +注册。当LLD注册其首个HBA时，SCSI中间层首次感受到该LLD的存在。 + +在稍后的某个时间点，当LLD检测到新的HBA时，接下来在LLD与SCSI +中间层之间会发生一系列典型的调用过程。该示例展示了中间层如何 +扫描新引入的HBA，在该过程中发现了3个SCSI设备，其中只有前两个 +设备有响应:: + + HBA探测：假设在扫描中发现2个SCSI设备 + 底层驱动 中间层 底层驱动 + =======---------------======---------------======= + scsi_host_alloc() --> +

+HBA的热插拔是一个特殊的场景，特别是当HBA下的磁盘正在处理已挂 +载文件系统上的SCSI命令时。为了应对其中的诸多问题，中间层引入 +了引用计数逻辑。具体内容参考下文关于引用计数的章节。 + +热插拔概念同样适用于SCSI设备。目前，当添加HBA时， +scsi_scan_host() 函数会扫描该HBA所属SCSI传输通道上的设备。在

+对于LLD而言，跟踪struct scsi_device实例可能会非常有用（该结构 +的指针会作为参数传递给sdev_init()和sdev_configure()回调函数）。 +这些实例的所有权归属于中间层（mid-level）。struct scsi_device +实例在sdev_destroy()执行后释放。 + +引用计数 +======== +Scsi_Host结构体已引入引用计数机制。该机制将struct Scsi_Host +实例的所有权分散到使用他的各SCSI层，而此前这类实例完全由中间 +层独占管理。底层驱动（LLD）通常无需直接操作这些引用计数，仅在 +某些特定场景下可能需要介入。 + +与struct Scsi_Host相关的引用计数函数主要有以下3种： + + - scsi_host_alloc(): + 返回指向新实例的指针，该实例的引用计数被设置为1。 + + - scsi_host_get(): + 给定实例的引用计数加1。 + + - scsi_host_put(): + 给定实例的引用计数减1。如果引用计数减少到0，则释放该实例。 + +scsi_device结构体现已引入引用计数机制。该机制将 +struct scsi_device实例的所有权分散到使用他的各SCSI层，而此 +前这类实例完全由中间层独占管理。相关访问函数声明详见 +include/scsi/scsi_device.h文件末尾部分。若LLD需要保留 +scsi_device实例的指针副本，则应调用scsi_device_get()增加其 +引用计数；不再需要该指针时，可通过scsi_device_put()递减引用 +计数（该操作可能会导致该实例被释放）。 + +.. Note:: + + struct Scsi_Host实际上包含两个并行维护的引用计数器，该引 + 用计数由这些函数共同操作。 + +编码规范 +======== + +首先，Linus Torvalds关于C语言编码风格的观点可以在 +Documentation/process/coding-style.rst文件中找到。 + +此外，在相关gcc编译器支持的前提下，鼓励使用大多数C99标准的增强 +特性。因此，在适当的情况下鼓励使用C99风格的结构体和数组初始化 +方式。但不要过度使用，目前对可变长度数组（VLA）的支持还待完善。 +一个例外是 ``//`` 风格的注释；在Linux中倾向于使 +用 ``/*...*/`` 注释格式。 + +对于编写良好、经过充分测试且有完整文档的代码不需要重新格式化 +以符合上述规范。例如，aic7xxx驱动是从FreeBSD和Adaptec代码库 +移植到Linux的。毫无疑问，FreeBSD和Adaptec遵循其原有的编码规 +范。 + + +中间层提供的函数 +================ +这些函数由SCSI中间层提供，供底层驱动（LLD）调用。这些函数的名 +称（即入口点）均已导出，因此作为模块加载的LLD可以访问他们。内 +核会确保在任何LLD初始化之前，SCSI中间层已先行加载并完成初始化。 +下文按字母顺序列出这些函数，其名称均以 ``scsi_`` 开头。 + +摘要： + + -

[#] 在极端情况下，单个驱动需要控制多种不同类型的硬件时，驱动可 + 能包含多个实例，（例如某个LLD驱动同时处理ISA和PCI两种类型 + 的适配卡，并为每种硬件类型维护独立的 + struct scsi_host_template实例）。 + +struct Scsi_Host +---------------- +每个由LLD控制的主机适配器对应一个struct Scsi_Host实例。 +该结构体与struct scsi_host_template具有多个相同成员。 +当创建struct Scsi_Host实例时（通过hosts.c中的 +scsi_host_alloc()函数），这些通用成员会从LLD的 +struct scsi_host_template实例初始化而来。关键成员说明 +如下： + + host_no + - 系统范围内唯一的主机标识号，按升序从0开始分配 + can_queue + - 必须大于0，表示适配器可处理的最大并发命令数，禁 + 止向适配器发送超过此数值的命令数 + this_id + - 主机适配器的SCSI ID（SCSI启动器标识），若未知则 + 设置为-1 + sg_tablesize + - 主机适配器支持的最大散列表（scatter-gather）元素 + 数。设置为SG_ALL或更小的值可避免使用链式SG列表， + 且最小值必须为1 + max_sectors + - 单个SCSI命令中允许的最大扇区数（通常为512字节/ + 扇区）。默认值为0，此时会使用 + SCSI_DEFAULT_MAX_SECTORS（在scsi_host.h中定义）， + 当前该值为1024。因此，如果未定义max_sectors，则磁盘的 + 最大传输大小为512KB。注意：这个大小可能不足以支持 + 磁盘固件上传。 + cmd_per_lun + - 主机适配器的设备上，每个LUN可排队的最大命令数。 + 此值可通过LLD调用scsi_change_queue_depth()进行 + 调整。 + hostt + - 指向LLD struct scsi_host_template实例的指针， + 当前struct Scsi_Host实例正是由此模板生成。 + hostt->proc_name + - LLD的名称，sysfs使用的驱动名。 + transportt + - 指向LLD struct scsi_transport_template实例的指 + 针（如果存在）。当前支持FC与SPI传输协议。 + hostdata[0] + - 为LLD在struct Scsi_Host结构体末尾预留的区域，大小由 + scsi_host_alloc()的第二个参数(privsize)决定。 + +scsi_host结构体的完整定义详见include/scsi/scsi_host.h。 + +struct scsi_device +------------------ +通常而言，每个SCSI逻辑单元（Logical Unit）对应一个该结构 +的实例。连接到主机适配器的SCSI设备通过三个要素唯一标识：通 +道号（Channel Number）、目标ID（Target ID）和逻辑单元号 +（LUN）。 +该结构体完整定义于include/scsi/scsi_device.h。 + +struct scsi_cmnd +---------------- +该结构体实例用于在LLD与SCSI中间层之间传递SCSI命令 +及其响应。SCSI中间层会确保：提交到LLD的命令数不超过 +scsi_change_queue_depth()（或struct Scsi_Host::cmd_per_lun） +设定的上限，且每个SCSI设备至少分配一个struct scsi_cmnd实例。 +关键成员说明如下： + + cmnd + - 包含SCSI命令的数组 + cmd_len + - SCSI命令的长度（字节为单位） + sc_data_direction + - 数据的传输方向。请参考 + include/linux/dma-mapping.h中的 + “enum dma_data_direction”。 + result + - LLD在调用“done”之前设置该值。值为0表示命令成功 + 完成（并且所有数据（如果有）已成功在主机与SCSI + 目标设备之间完成传输）。“result”是一个32位无符 + 号整数，可以视为2个相关字节。SCSI状态值位于最 + 低有效位。请参考include/scsi/scsi.h中的 + status_byte()与host_byte()宏以及其相关常量。 + sense_buffer + - 这是一个数组（最大长度为SCSI_SENSE_BUFFERSIZE + 字节），当SCSI状态（“result”的最低有效位）设为 + CHECK_CONDITION（2）时，该数组由LLD填写。若 + CHECK_CONDITION被置位，且sense_buffer[0]的高 + 半字节值为7，则中间层会认为sense_buffer数组 + 包含有效的SCSI感知数据；否则，中间层会发送 + REQUEST_SENSE SCSI命令来获取感知数据。由于命令 + 排队的存在，后一种方式容易出错，因此建议LLD始终 + 支持“自动感知”。 + device + - 指向与该命令关联的scsi_device对象的指针。 + resid_len (通过调用scsi_set_resid() / scsi_get_resid()访问) + - LLD应将此无符号整数设置为请求的传输长度（即 + “request_bufflen”）减去实际传输的字节数。“resid_len” + 默认设置为0，因此如果LLD无法检测到数据欠载（不能报告溢出）， + 则可以忽略它。LLD应在调用“done”之前设置 + “resid_len”。 + underflow + - 如果实际传输的字节数小于该字段值，LLD应将 + DID_ERROR << 16赋值给“result”。并非所有 + LLD都实现此项检查，部分LLD仅将错误信息输出 + 到日志，而未真正报告DID_ERROR。更推荐 + 的做法是由LLD实现“resid_len”的支持。 + +建议LLD在从SCSI目标设备进行数据传输时设置“resid_len”字段 +（例如READ操作）。当这些数据传输的感知码是MEDIUM ERROR或 +HARDWARE ERROR（有时也包括RECOVERED ERROR）时设置 +resid_len尤为重要。在这种情况下，如果LLD无法确定接收了多 +少数据，那么最安全的做法是表示没有接收到任何数据。例如： +为了表明没有接收到任何有效数据，LLD可以使用如下辅助函数:: + + scsi_set_resid(SCpnt, scsi_bufflen(SCpnt)); + +其中SCpnt是一个指向scsi_cmnd对象的指针。如果表示仅接收到 +三个512字节的数据块，可以这样设置resid_len:: + + scsi_set_resid(SCpnt, scsi_bufflen(SCpnt) - (3 * 512)); + +scsi_cmnd结构体定义在 include/scsi/scsi_cmnd.h文件中。 + + +锁 +=== +每个struct Scsi_Host实例都有一个名为default_lock +的自旋锁（spin_lock），它在scsi_host_alloc()函数 +中初始化（该函数定义在hosts.c文件中）。在同一个函数 +中，struct Scsi_Host::host_lock指针会被初始化为指 +向default_lock。此后，SCSI中间层执行的加 +锁和解锁操作都会使用host_lock指针。过去，驱动程序可 +以重写host_lock指针，但现在不再允许这样做。 + + +自动感知 +======== +自动感知（Autosense或auto-sense）在SAM-2规范中被定 +义为：当SCSI命令完成状态为CHECK CONDITION时，“自动 +将感知数据（sense data）返回给应用程序客户端”。底层 +驱动（LLD）应当执行自动感知。当LLD检测到 +CHECK CONDITION状态时，可通过以下任一方式完成： + + a) 要求SCSI协议（例如SCSI并行接口（SPI））在此 + 类响应中执行一次额外的数据传输 + + b) 或由LLD主动发起REQUEST SENSE命令获取感知数据 + +无论采用哪种方式，当检测到CHECK CONDITION状态时，中 +间层通过检查结构体scsi_cmnd::sense_buffer[0]的值来 +判断LLD是否已执行自动感知。若该字节的高半字节为7 +（或 0xf），则认为已执行自动感知；若该字节为其他值 +（且此字节在每条命令执行前会被初始化为0），则中间层将 +主动发起REQUEST SENSE命令。 + +在存在命令队列的场景下，保存失败命令感知数据的“nexus” +可能会在等待REQUEST SENSE命令期间变得不同步。因此， +最佳实践是由LLD执行自动感知。 + + +自Linux内核2.4以来的变更 +======================== +io_request_lock已被多个细粒度锁替代。与底层驱动 +（LLD）相关的锁是struct Scsi_Host::host_lock，且每 +个SCSI主机都独立拥有一个该锁。 + +旧的错误处理机制已经被移除。这意味着LLD的接口函数 +abort()与reset()已经被删除。 +struct scsi_host_template::use_new_eh_code标志 +也已经被移除。 + +在Linux内核2.4中，SCSI子系统的配置描述与其他Linux子系 +统的配置描述集中存放在Documentation/Configure.help +文件中。在Linux内核2.6中，SCSI子系统拥有独立的配置文 +件drivers/scsi/Kconfig（体积更小），同时包含配置信息 +与帮助信息。 + +struct SHT已重命名为struct scsi_host_template。 + +新增“热插拔初始化模型”以及许多用于支持该功能的额外函数。 + + +致谢 +==== +以下人员对本文档做出了贡献： + + - Mike Anderson + - James Bottomley + - Patrick Mansfield + - Christoph Hellwig + - Doug Ledford + - Andries Brouwer + - Randy Dunlap + - Alan Stern + + +Douglas Gilbert +dgilbert at interlog dot com + +2004年9月21日 diff --git a/Documentation/translations/zh_CN/scsi/sd-parameters.rst b/Documentation/translations/zh_CN/scsi/sd-parameters.rst new file mode 100644 index 000000000000..b3d0445dc9f3 --- /dev/null +++ b/Documentation/translations/zh_CN/scsi/sd-parameters.rst @@ -0,0 +1,38 @@ +..

NOTE:: + + 这是针对开发人员而不是管理员的文档。如果您正在 + 寻找有关IPE使用的文档，请参阅 :doc:`IPE admin + guide `。 + +历史背景 +-------- + +最初促使IPE实施的原因，是需要创建一个锁定式系统。该系统将 +从一开始就具备安全性，并且在可执行代码和系统功能关键的特定 +数据文件上，提供强有力的完整性保障。只有当这些特定数据文件 +符合完整性策略时，它们才可以被读取。系统中还将存在强制访问 +控制机制，因此扩展属性（xattrs）也必须受到保护。这就引出了 +需要选择能够提供完整性保证的机制。当时，有两种主要机制被考 +虑，用以在满足这些要求的前提下保证系统完整性： + + 1. IMA + EVM Signatures + 2. DM-Verity + +这两个选项都经过了仔细考虑，然而在原始的IPE使用场景 +中，最终选择DM-Verity而非IMA+EVM作为完整性机制，主 +要有三个原因： + + 1. 防护额外的攻击途径 + + * 使用IMA+EVM时，如果没有加密解决方案，系统很容易受到 + 离线攻击，特别是针对上述特定数据文件的攻击。 + + 与可执行文件不同，读取操作（如对受保护数据文件的读 + 取操作）无法强制性进行全局完整性验证。这意味着必须 + 有一种选择机制来决定是否应对某个读取操作实施完整性 + 策略。 + + 在当时，这是通过强制访问控制标签来实现的，IMA策略会 + 指定哪些标签需要进行完整性验证，这带来了一个问题： + EVM虽然可以保护标签，但如果攻击者离线修改文件系统， + 那么攻击者就可以清除所有的扩展属性（xattrs）——包括 + 用于确定文件是否应受完整性策略约束的SELinux标签。 + + 使用DM-Verity，由于xattrs被保存为Merkel树的一部分， + 如果对由dm-verity保护的文件系统进行了离线挂载，校验 + 和将不在匹配，文件将无法读取。 + + * 由于用户空间的二进制文件在Linux中是分页加载的，dm- + verity同样提供了对抗恶意块设备的额外保护。在这样的 + 攻击中，块设备最初报告适当的内容以供IMA哈希计算，通 + 过所需的完整性检查。然后，在访问真实数据时发生的页面 + 错误将报告攻击者的有效载荷。由于dm-verity会在页面错 + 误发生时检查数据（以及磁盘访问），因此这种攻击得到了 + 缓解。 + + 2. 性能: + + * dm-verity在块被读取时按需提供完整性验证，而不需要将整 + 个文件读入内存进行验证。 + + 3. 签名的简化性: + + * 不需要两个签名（IMA 然后是 EVM）：一个签名可以覆盖整个 + 块设备。 + * 签名可以存储在文件系统元数据之外。 + * 该签名支持基于 x.509 的签名基础设施。 + +下一步是选择一个策略来执行完整性验证机制，该策略的最低 +要求是： + + 1. 策略本身必须经过完整性验证（防止针对它的简单攻击）。 + 2. 策略本身必须抵抗回滚攻击。 + 3. 策略执行必须具有类似宽松模式的功能。 + 4. 策略必须能够在不重启的情况下，完整地进行更新。 + 5. 策略更新必须是原子性的。 + 6. 策略必须支持撤销先前创建的组件。 + 7. 策略必须在任何时间点都能进行审计。 + +当时，IMA作为唯一的完整性策略机制，被用来与这些要求进行对比， +但未能满足所有最低要求。尽管考虑过扩展IMA以涵盖这些要求，但 +最终因两个原因被放弃： + + 1. 回归风险；这其中许多变更将导致对已经存在于内核的IMA进行 + 重大代码更改，因此可能会影响用户。 + + 2. IMA在该系统中用于测量和证明；将测量策略与本地完整性策略 + 的执行分离被认为是有利的。 + +由于这些原因，决定创建一个新的LSM，其职责是仅限于本地完整性 +策略的执行。 + +职责和范围 +---------- + +IPE顾名思义，本质上是一种完整性策略执行解决方案；IPE并不强制规定 +如何提供完整性保障，而是将这一决策权留给系统管理员，管理员根据自身 +需求，选择符合的机制来设定安全标准。存在几种不同的完整性解决方案， +它们提供了不同程度的安全保障；而IPE允许系统管理员理论上为所有这些 +解决方案制定策略。 + +IPE自身没有内置确保完整性的固有机制。相反，在构建具备完整性保障能力 +的系统时，存在更高效的分层方案可供使用。需要重点注意的是，用于证明完 +整性的机制，与用于执行完整性声明的策略是相互独立的。 + +因此，IPE依据以下方面进行设计： + + 1. 便于与完整性提供机制集成。 + 2. 便于平台管理员/系统管理员使用。 + +设计理由: +--------- + +IPE是在评估其他操作系统和环境中的现有完整性策略解决方案后设计的。 +在对其他实现的调查中，发现了一些缺陷： + + 1. 策略不易为人们读取，通常需要二进制中间格式。 + 2. 默认情况下会隐式采取单一的、不可定制的操作。 + 3. 调试策略需要手动来确定违反了哪个规则。 + 4. 编写策略需要对更大系统或操作系统有深入的了解。 + +IPE尝试避免所有这些缺陷。 + +策略 +~~~~ + +纯文本 +^^^^^^ + +IPE的策略是纯文本格式的。相较于其他Linux安全模块（LSM）， +策略文件体积略大，但能解决其他平台上部分完整性策略方案存在 +的两个核心问题。 + +第一个问题是代码维护和冗余的问题。为了编写策略，策略必须是 +以某种形式的字符串形式呈现（无论是 XML、JSON、YAML 等结构化 +格式，还是其他形式），以便策略编写者能够理解所写内容。在假设 +的二进制策略设计中，需要一个序列化器将策略将可读的形式转换为 +二进制形式，同时还需要一个反序列化器来将二进制形式转换为内核 +中的数据结构。 + +最终，还需要另一个反序列化器将是必要的，用于将二进制形式转换 +为人类可读的形式，并尽可能保存所有信息，这是因为使用此访问控 +制系统的用户必须维护一个校验表和原始文件，才能理解哪些策略已 +经部署在该系统上，哪些没有。对于单个用户来说，这可能没问题， +因为旧的策略可以在更新生效后很快被丢弃。但对于管理成千上万、 +甚至数十万台计算机的用户，且这些计算机有不同的操作系统和不同 +的操作需求，这很快就成了一个问题，因为数年前的过时策略可能仍然 +存在，从而导致需要快速恢复策略或投资大量基础设施来跟踪每个策略 +的内容。 + +有了这三个独立的序列化器/反序列化器，维护成本非常昂贵。如果策略 +避免使用二进制格式，则只需要一个序列化器；将人类可读的形式转换 +为内核中的数据结构。从而节省了代码维护成本，并保持了可操作性。 + +第二个关于二进制格式的问题是透明性，由于IPE根据系统资源的可信度 +来控制访问，因此其策略也必须可信，以便可以被更改。这是通过签名来 +完成的，这就需要签名过程。签名过程通常具有很高的安全标准，因为 +任何被签名的内容都可以被用来攻击完整性执行系统。签署时，签署者 +必须知道他们在签署什么，二进制策略可能会导致这一点的模糊化；签署 +者看到的只是一个不透明的二进制数据块。另一方面，对于纯文本策略中， +签署者看到的则是实际提交的策略。 + +启动策略 +~~~~~~~~ + +如果配置得当，IPE能够在内核启动并进入用户模式时立即执行策略。 +这意味着需要在用户模式开始的那一刻就存储一定的策略。通常，这种 +存储可以通过一下三种方式之一来处理： + + 1. 策略文件存储在磁盘上，内核在进入可能需要做出执行决策的代码 + 路径之前，先加载该策略。 + 2. 策略文件由引导加载程序传递给内核，内核解析这些策略。 + 3. 将一个策略文件编译到内核中，内核在初始化过程中对其进行解析并 + 执行。 + +第一种方式存在问题：内核从用户空间读取文件通常是不推荐的，并且在 +内核中极为罕见。 + +第二种选项同样存在问题：Linux在其整个生态系统中支持多种引导加载程序， +所有引导加载程序都必须支持这种新方法，或者需要有一个独立的来源，这 +可能会导致内核启动过程发生不必要的重大变化。 + +第三种选项是最佳选择，但需要注意的是，编译进内核的策略会占用磁盘空间。 +重要的是要使这一策略足够通用，以便用户空间能够加载新的、更复杂的策略， +同时也要足够严格，以防止过度授权并避免引发安全问题。 + +initramfs提供了一种建立此启动路径的方法。内核启动时以最小化的策略启动， +该策略仅信任initramfs。在initramfs内，当真实的根文件系统已挂载且尚未 +切换时，它会部署并激活一个信任新根文件系统的策略。这种方法防止了在任何 +步骤中出现过度授权，并保持内核策略的最小化。 + +启动 +^^^^ + +然而，并不是每个系统都以initramfs启动，因此编译进内核的启动策略需要具备 +一定的灵活性，以明确如何为启动的下一个阶段建立信任。为此，如果我们将编译 +进内核的策略设计为一个完整的IPE策略，这样系统构建者便能合理定义第一阶段启 +动的需求。 + +可更新、无需重启的策略 +~~~~~~~~~~~~~~~~~~~~~~ + +随着时间的推移，系统需求发生变化（例如，之前信任的应用程序中发现漏洞、秘钥 +轮换等）。更新内核以满足这些安全目标并非始终是一个合适的选择，因为内核更新并 +非完全无风险的，而搁置安全更新会使系统处于脆弱状态。这意味着IPE需要一个可以 +完全更新的策略（允许撤销现有的策略），并且这个更新来源必须是内核外部的（允许 +再不更新内核的情况下更新策略）。 + +此外，由于内核在调用之间是无状态的，并且从内核空间读取磁盘上的策略文件不是一 +个好主意，因此策略更新必须能够在不重启的情况下完成。 + +为了允许从外部来源进行更新，考虑到外部来源可能是恶意的，因此该策略需要具备可被 +识别为可信的机制。这一机制通过签名链实现：策略的签名需与内核中的某个信任源相 +关联。通常，这个信任源是 ``SYSTEM_TRUSTED_KEYRING`` ，这是一个在内核编译时就被 +初始化填充的密钥环，因为这符合上述编译进来策略的制作者与能够部署策略更新的实体 +相同的预期。 + +防回滚 / 防重放 +~~~~~~~~~~~~~~~ + +随着时间的推移，系统可能会发现漏洞，曾经受信任的资源可能不再可信，IPE的 +策略也不例外。可能会出现的情况是，策略制作者误部署了一个不安全的策略， +随后再用一个安全的策略进行修正。 + +假设一旦不安全的策略被部署，攻击者获取了这个不安全的策略，IPE需要有一种 +方式来防止从安全的策略更新回滚到不安全的策略。 + +最初，IPE的策略可以包含一个policy_version字段，声明系统上所有可激活策略 +所需的最低版本号。这将在系统运行期间防止回滚。 + +.. WARNING:: + + 然而，由于内核每次启动都是无状态的，因此该策略版本将在下次 + 启动时被重置为0.0.0。系统构建者需要意识到这一点，并确保在启 + 动后尽快部署新的安全策略，以确保攻击者部署不安全的策略的几 + 率最小化。 + +隐式操作: +~~~~~~~~~ + +隐式操作的问题只有在考虑系统中多个操作具有不同级别时才会显现出来。 +例如，考虑一个系统，该系统对可执行代码和系统中对其功能至关重要的 +特定数据提供强大的完整性保障。在这个系统中，可能存在三种类型的 +策略： + + 1. 一种策略，在这种策略中，如果操作未能匹配到任何规则，则该操 + 作将被拒绝。 + 2. 一种策略，在这种策略中，如果操作未能匹配到任何规则，则该操 + 作将被允许。 + 3. 一种策略，在这种策略中，如果操作未能匹配到任何规则，则执行 + 操作由策略作者指定。 + +第一种类型的策略示例如下:: + + op=EXECUTE integrity_verified=YES action=ALLOW + +在示例系统中，这对于可执行文件来说效果很好，因为所有可执行文件 +都应该拥有完整性保障。但问题出现在第二个要求上，即关于特定数据 +文件的要求。这将导致如下策略（假设策略按行依次执行）:: + + op=EXECUTE integrity_verified=YES action=ALLOW + + op=READ integrity_verified=NO label=critical_t action=DENY + op=READ action=ALLOW + +若阅读过文档，了解策略按顺序执行且默认动作是拒绝，那么这个策略的 +逻辑还算清晰；但最后一行规则实际上将读取操作的默认动作改成了允许。 +这种设计是必要的，因为在实际系统中，存在一些无需验证的读取操作（例 +如向日志文件追加内容时的读取操作）。 + +第二种策略类型（未匹配任何规则时默认允许）在管控特定数据文件时逻辑 +更清晰，其策略可简化为:: + + op=READ integrity_verified=NO label=critical_t action=DENY + +但与第一种策略类似，这种默认允许的策略在管控执行操作时会存在缺陷， +因此仍需显式覆盖默认动作:: + + op=EXECUTE integrity_verified=YES action=ALLOW + op=EXECUTE action=DENY + + op=READ integrity_verified=NO label=critical_t action=DENY + +这就引出了第三种策略类型（自定义默认动作）。该类型无需让用户绞尽脑汁 +通过空规则覆盖默认动作，而是强制用户根据自身场景思考合适的默认动作是 +什么，并显式声明:: + + DEFAULT op=EXECUTE action=DENY + op=EXECUTE integrity_verified=YES action=ALLOW + + DEFAULT op=READ action=ALLOW + op=READ integrity_verified=NO label=critical_t action=DENY + +策略调试: +~~~~~~~~~ + +在开发策略时，知道策略违反了哪一行有助于减少调试成本；可以 +将调查的范围缩小到导致该行为的确切行。有些完整性策略系统并 +不提供这一信息，而是提供评估过程中使用的信息。这随后需要将 +这些信息和策略进行关联，以分析哪里了问题。 + +相反，IPE只会输出匹配到的规则。这将调查范围限制到确切到策略行 +（在特定规则的情况下）或部分（在DEFAULT规则的情况下）。当在 +评估策略时观察到策略失败时，这可以减少迭代和调查的时间。 + +IPE的策略引擎还被设计成让人类容易理解如何调查策略失败。每一 +行都会按编写顺序进行评估，因此算法非常简单，便于人类重现步 +骤并找出可能导致失败的原因。而在调查其他的系统中，加载策略 +时会进行优化（例如对规则排序）。在这些系统中，调试需要多个 +步骤，而且没有先阅读代码的情况下，终端用户可能无法完全理解 +该算法的原理。 + +简化策略: +~~~~~~~~~ + +最后，IPE的策略是为系统管理员设计的，而不是内核开发人员。 +IPE不涉及单独的LSM钩子（或系统调用），而是涵盖操作。这 +意味着，系统管理员不需要知道像 ``mmap`` 、 ``mprotect`` 、 +``execve`` 和 ``uselib`` 这些系统调用必须有规则进行保护， +而只需要知道他们想要限制代码执行。这减少了由于缺乏对底层 +系统的了解而可能导致的绕过情况；而IPE的维护者作为内核开发 +人员，可以做出正确的选择，确定某些操作是否与这些操作匹配， +以及在什么条件下匹配。 + +实现说明 +-------- + +匿名内存 +~~~~~~~~ + +在IPE中，匿名内存的处理方式与其他任何类型的访问没有区别。当匿 +名内存使用 ``+X`` 映射时，它仍然会进入 ``file_mmp`` 或 +``file_mprotect`` 钩子，但此时会带有一个 ``NULL`` 文件对象 +这会像其他文件一样提交进行评估。然而，所有当前的信任属性都会 +评估为假，因为它们都是基于文件的，而此次操作并不与任何文件相关联。 + +.. WARNING:: + + 这也适用于 ``kernel_load_data`` 钩子，当内核从一个没有文件 + 支持的用户空间缓冲区加载数据时。在这种情况下，所有当前的信任 + 属性也将评估为false。 + +Securityfs接口 +~~~~~~~~~~~~~~ + +每个策略的对应的securityfs树是有些独特的。例如，对于一个标准的 +securityfs策略树:: + + MyPolicy + |- active + |- delete + |- name + |- pkcs7 + |- policy + |- update + |- version + +策略存储在MyPolicy对应节点的 ``->i_private`` 数据中。 + +测试 +---- + +IPE为策略解析器提供了KUnit测试。推荐kunitconfig:: + + CONFIG_KUNIT=y + CONFIG_SECURITY=y + CONFIG_SECURITYFS=y + CONFIG_PKCS7_MESSAGE_PARSER=y + CONFIG_SYSTEM_DATA_VERIFICATION=y + CONFIG_FS_VERITY=y + CONFIG_FS_VERITY_BUILTIN_SIGNATURES=y + CONFIG_BLOCK=y + CONFIG_MD=y + CONFIG_BLK_DEV_DM=y + CONFIG_DM_VERITY=y + CONFIG_DM_VERITY_VERIFY_ROOTHASH_SIG=y + CONFIG_NET=y + CONFIG_AUDIT=y + CONFIG_AUDITSYSCALL=y + CONFIG_BLK_DEV_INITRD=y + + CONFIG_SECURITY_IPE=y + CONFIG_IPE_PROP_DM_VERITY=y + CONFIG_IPE_PROP_DM_VERITY_SIGNATURE=y + CONFIG_IPE_PROP_FS_VERITY=y + CONFIG_IPE_PROP_FS_VERITY_BUILTIN_SIG=y + CONFIG_SECURITY_IPE_KUNIT_TEST=y + +此外，IPE 具有一个基于 Python 的集成 +`测试套件 `_ +可以测试用户界面和强制执行功能。 diff --git a/Documentation/translations/zh_CN/security/lsm-development.rst b/Documentation/translations/zh_CN/security/lsm-development.rst new file mode 100644 index 000000000000..7ed3719a9d07 --- /dev/null +++ b/Documentation/translations/zh_CN/security/lsm-development.rst @@ -0,0 +1,19 @@ +..

The x86_64-specific +approach relies on the CPUID Virtualization Stack leaf; the ARM64 implementation +is expected to support the Confidential VMBus unconditionally when running +ARM CCA guests. + +Confidential VMBus is a characteristic of the VMBus connection as a whole, +and of each VMBus channel that is created. When a Confidential VMBus +connection is established, the paravisor provides the guest the message-passing +path that is used for VMBus device creation and deletion, and it provides a +per-CPU synthetic interrupt controller (SynIC) just like the SynIC that is +offered by the Hyper-V host. Each VMBus device that is offered to the guest +indicates the degree to which it participates in Confidential VMBus. The offer +indicates if the device uses encrypted ring buffers, and if the device uses +encrypted memory for DMA that is done outside the ring buffer. These settings +may be different for different devices using the same Confidential VMBus +connection. + +Although these settings are separate, in practice it'll always be encrypted +ring buffer only, or both encrypted ring buffer and external data. If a channel +is offered by the paravisor with confidential VMBus, the ring buffer can always +be encrypted since it's strictly for communication between the VTL2 paravisor +and the VTL0 guest. However, other memory regions are often used for e.g. DMA, +so they need to be accessible by the underlying hardware, and must be +unencrypted (unless the device supports encrypted memory). Currently, there are +not any VSPs in OpenHCL that support encrypted external memory, but future +versions are expected to enable this capability. + +Because some devices on a Confidential VMBus may require decrypted ring buffers +and DMA transfers, the guest must interact with two SynICs -- the one provided +by the paravisor and the one provided by the Hyper-V host when Confidential +VMBus is not offered. Interrupts are always signaled by the paravisor SynIC, +but the guest must check for messages and for channel interrupts on both SynICs. + +In the case of a confidential VMBus, regular SynIC access by the guest is +intercepted by the paravisor (this includes various MSRs such as the SIMP and +SIEFP, as well as hypercalls like HvPostMessage and HvSignalEvent). If the +guest actually wants to communicate with the hypervisor, it has to use special +mechanisms (GHCB page on SNP, or tdcall on TDX). Messages can be of either +kind: with confidential VMBus, messages use the paravisor SynIC, and if the +guest chose to communicate directly to the hypervisor, they use the hypervisor +SynIC. For interrupt signaling, some channels may be running on the host +(non-confidential, using the VMBus relay) and use the hypervisor SynIC, and +some on the paravisor and use its SynIC.

Note that this is not + * enough to deal with EOImode=1, see below. + * + * - if the overall number of interrupts exceeds the number of LRs, + * then UIE must be set to allow refilling of the LRs once the + * majority of them has been processed. + * + * - as usual, MI triggers are only an optimisation, since we cannot + * rely on the MI being delivered in timely manner... + * + * - EOImode=1 creates some additional problems: + * + * - deactivation can happen in any order, and we cannot rely on + * EOImode=0's coupling of priority-drop and deactivation which + * imposes strict reverse Ack order. This means that DIR must + * trap if we have active interrupts outside of the LRs. + * + * - deactivation of SPIs can occur on any CPU, while the SPI is only + * present in the ap_list of the CPU that actually ack-ed it. In that + * case, EOIcount doesn't provide enough information, and we must + * resort to trapping DIR even if we don't overflow the LRs. Bonus + * point for not trapping DIR when no SPIs are pending or active in + * the whole VM. + * + * - LPIs do not suffer the same problem as SPIs on deactivation, as we + * have to essentially discard the active state, see below. + * + * - Virtual LPIs have an active state (surprise!), which gets removed on + * priority drop (EOI). However, EOIcount doesn't get bumped when the LPI + * is not present in the LR (surprise again!). Special care must therefore + * be taken to remove the active state from any activated LPI when exiting + * from the guest. This is in a way no different from what happens on the + * physical side.
