Thank you to [makeareadme.com](https://www.makeareadme.com/) for this template. - -## Suggestions for a good README -Every project is different, so consider which of these sections apply to yours. The sections used in the template are suggestions for most open source projects. Also keep in mind that while a README can be too long and detailed, too long is better than too short. If you think your README is too long, consider utilizing another form of documentation rather than cutting out information. - -## Name -Choose a self-explaining name for your project. - -## Description -Let people know what your project can do specifically. Provide context and add a link to any reference visitors might be unfamiliar with. A list of Features or a Background subsection can also be added here. If there are alternatives to your project, this is a good place to list differentiating factors. - -## Badges -On some READMEs, you may see small images that convey metadata, such as whether or not all the tests are passing for the project. You can use Shields to add some to your README. Many services also have instructions for adding a badge. - -## Visuals -Depending on what you are making, it can be a good idea to include screenshots or even a video (you'll frequently see GIFs rather than actual videos). Tools like ttygif can help, but check out Asciinema for a more sophisticated method. - -## Installation -Within a particular ecosystem, there may be a common way of installing things, such as using Yarn, NuGet, or Homebrew. However, consider the possibility that whoever is reading your README is a novice and would like more guidance. Listing specific steps helps remove ambiguity and gets people to using your project as quickly as possible. If it only runs in a specific context like a particular programming language version or operating system or has dependencies that have to be installed manually, also add a Requirements subsection. - -## Usage -Use examples liberally, and show the expected output if you can. It's helpful to have inline the smallest example of usage that you can demonstrate, while providing links to more sophisticated examples if they are too long to reasonably include in the README. - -## Support -Tell people where they can go to for help. It can be any combination of an issue tracker, a chat room, an email address, etc. - -## Roadmap -If you have ideas for releases in the future, it is a good idea to list them in the README. - -## Contributing -State if you are open to contributions and what your requirements are for accepting them. - -For people who want to make changes to your project, it's helpful to have some documentation on how to get started. Perhaps there is a script that they should run or some environment variables that they need to set. Make these steps explicit. These instructions could also be useful to your future self. - -You can also document commands to lint the code or run tests. These steps help to ensure high code quality and reduce the likelihood that the changes inadvertently break something. Having instructions for running tests is especially helpful if it requires external setup, such as starting a Selenium server for testing in a browser. - -## Authors and acknowledgment -Show your appreciation to those who have contributed to the project. - -## License -For open source projects, say how it is licensed. - -## Project status -If you have run out of energy or time for your project, put a note at the top of the README saying that development has slowed down or stopped completely. Someone may choose to fork your project or volunteer to step in as a maintainer or owner, allowing your project to keep going. You can also make an explicit request for maintainers. diff --git a/kernel6/stuct.puml b/kernel6/stuct.puml new file mode 100644 index 0000000..8c8bc3b --- /dev/null +++ b/kernel6/stuct.puml @@ -0,0 +1,72 @@ +@startuml my + +struct uintr_upid { + struct { + u8 status; /* bit 0: ON, bit 1: SN,bit 7 : STATUS_BLKD, bit 2-6: reserved */ + u8 reserved1; /* Reserved */ + u8 nv; /* Notification vector */ + u8 reserved2; /* Reserved */ + u32 ndst; /* Notification destination */ + } nc __packed; /* Notification control */ + u64 puir; /* Posted user interrupt requests */ /*pir 发送方向量*/ +} + +struct uintr_upid_ctx { + struct list_head node; + struct task_struct *task; /* Receiver task */ // 接收方进程 + u64 uvec_mask; // 跟踪注册的每一个向量 + struct uintr_upid *upid; // 接收方的 UPID + refcount_t refs; / 线程安全的引用计数 + bool receiver_active; /* Flag for UPID being mapped to a receiver */ + bool waiting; // 是否在等待 + +unsigned int waiting_cost; /* Flags for who pays the waiting cost */ +} + +struct uintr_uitt_entry { + u8 valid; /* bit 0: valid, bit 1-7: reserved */ + u8 user_vec; + u8 reserved[6]; + u64 target_upid_addr; +} + +struct uintr_uitt_ctx { + struct uintr_uitt_entry *uitt; // list,透过指针运算取得 uitt_entry + /* Protect UITT */ + spinlock_t uitt_lock; + refcount_t refs; // 引用计数 + +u64 uitt_mask[BITS_TO_U64(UINTR_MAX_UITT_NR)]; + +struct uintr_upid_ctx *r_upid_ctx[UINTR_MAX_UITT_NR]; +} + +struct uvecfd_ctx { + struct uintr_upid_ctx *upid_ctx; /* UPID context */ + u64 uvec; /* Vector number */ +} + +struct thread_struct { + /* Signifies whether the MSRs for that thread are active */ + +unsigned int uitt_activated:1; + +unsigned int upid_activated:1; + +struct uintr_upid_ctx *upid_ctx;/* Pointer to the UPID context for the task */ + +struct mm_struct *mm; +} + +struct mm_context_t { + struct uintr_uitt_ctx *uitt_ctx; +} + +uvecfd_ctx o-- uintr_upid_ctx : one + +uintr_uitt_ctx o-- uintr_uitt_entry : list + +uintr_upid_ctx -down-> uintr_upid : contains + +uintr_wait_list o-- uintr_upid_ctx : list + +thread_struct -down-> uintr_upid_ctx : contains + +thread_struct -down-> mm_context_t : contains + +mm_context_t -down-> uintr_uitt_ctx : contains + +@enduml

表条目，并将中断向量（63-0）发布到接收器的 UPID 中。 + +如果接收器正在运行（CPL=3），发送方 CPU 将向接收器 CPU 发送一个物理 IPI。在接收方侧，这个 IPI 被检测为用户中断。接收器的用户中断处理程序被调用，并将向量号（63-0）推送到堆栈中。 + +在中断处理程序执行 "uiret" 后，控制被转移到被中断的指令处。 +

+如果接收方正在运行（CPL=3），则直接传递用户中断，无需内核转换。如果接收方未运行，则在接收方重新上下文切换时传递中断。如果接收方被阻塞在内核中，则将用户中断传递给内核，然后解除预期的接收方以传递中断。 + +4b) 如果发送方是内核或设备，则可以将 uintr_fd 传递到相关的内核实体以允许它们建立连接，然后生成用户中断以进行事件传递。 <该 API 的确切细节仍在努力工作中。> +

CPU 功能的问题。此外，我们希望每个向量都有一个用户中断 FD，并在所有向量之间共享一个公共中断处理程序。这似乎更容易通过基于系统调用的方法来实现。 + +使用用户中断共享/传输数据：Uintr 不包括共享/传输数据的机制。期望应用程序使用现有的数据共享机制来共享数据，仅使用 Uintr 进行信号传递。 + +为每个向量分配一个 FD：为每个向量分配一个 uintr_fd，以允许接收方进行精细的优先级和事件管理。我们考虑的另一种选择是将 FD 分配给中断处理程序，并将其与发送方共享。但是，这种方法依赖于发送方选择向量，并将向量优先级管理移动到发送方。此外，如果多个发送方想要发送独特的用户中断，它们需要在它们之间协调向量选择。 + +扩展 API：目前，系统调用仅可使用标志参数进行扩展。如果需要，我们可以向某些系统调用添加可变大小的结构。 + +## 扩展现有机制 + +在某些使用 eventfd() 或信号的用途中，Uintr 可能很有用。由于 Uintr 是硬件相关的、线程特定的，并且在快速路径中绕过内核，因此它使扩展现有机制变得更加困难。 + +扩展信号的主要问题： +信号处理程序与用户中断处理程序的定义方式有很大的不同。应用程序需要在用户中断处理程序中保存/恢复寄存器并调用 uiret 进行返回。此外，信号可以是进程导向的（或线程导向的），但用户中断始终是线程导向的。 + +将信号与用户中断进行比较： ++=====================+===========================+===========================+ +| | 信号 | 用户中断 | ++=====================+===========================+===========================+ +| 堆栈 | 具有备选堆栈 | 使用应用程序堆栈 | +| | | （尚未启用备选堆栈选项） |

++--------------------+----------------------+------------------------------+ + + +# 安全模型 + +用户中断是一种自愿选择的功能（不像信号）。用户中断的安全模型旨在类似于 eventfd()。一般的想法是，任何具有 uintr_fd 访问权限的发送方都可以为创建了该 fd 的接收任务生成关联的中断向量。 + +## 不受信任的进程 + +当前的实现预计只有可信且协同的进程使用用户中断进行通信。在协调连接拆除的情况下，期望进程之间进行协调。在协调不发生的情况下（比如由于进程突然退出），内核将继续保持共享资源（如 UPID）分配以避免故障。 + +目前，发送方可以通过生成一连串的用户中断轻易地导致接收方的拒绝服务。用户中断处理程序在禁用中断的情况下被调用，但在执行 uiret 后，硬件会再次启用中断。这可能会导致在正常执行恢复之前再次调用处理程序。没有硬件机制来屏蔽特定的中断向量。 + +为了使不受信任的进程能够进行通信，我们需要通过另一个系统调用（或者可能是 IOCTL）添加每个向量屏蔽选项。但是，这可能会增加内核代码的复杂性。只能通过修改源头的 UITT 条目来屏蔽向量。在删除和恢复 UITT 的 UPID 时，我们需要小心竞态条件。 + +## 资源限制 + +接收方-发送方连接的最大数量将受到打开文件描述符的最大数量和 UITT 大小的限制。 + +目前，UITT 大小是任意选择的 4kB 固定大小。我们计划将其更改为动态和可配置的大小。当达到大小限制时，应触发 RLIMIT_MEMLOCK 或 ENOMEM。 + +# 主要开放 + +## 中断阻塞 + +如果应用程序在用户空间运行，则用户中断会立即传递给应用程序。如果接收任务使用占位符 uintr_wait() 系统调用在内核中阻塞，任务将被唤醒以传递用户中断。但是，如果任务由于任何其他阻塞调用（如 read()、sleep() 等）而被阻塞，则只有在应用程序再次调度时才会传递中断。我们需要考虑如果应用程序需要在发布时立即接收用户中断（类似于信号），当它们由于某些其他原因而被阻塞时。添加此功能可能会使内核实现更加复杂。 + +使用用户中断中断系统调用也意味着我们需要考虑一种 SA_RESTART 类型的机制。我们还需要评估内核中是否可以重用一些与信号处理程序相关的语义来处理用户中断。 + +## 共享用户中断目标表（UITT） + +当前实现为每个任务分配一个唯一的 UITT。这意味着用户中断用于两个任务之间的点对点通信。此外，这使得内核实现相对简单。 + +但是，共享 UITT 对于多线程应用程序的线程之间也有好处。其中一个好处是，它们将看到 UITT 的一致视图。即 SENDUIPI <index> 在应用程序的所有线程上都具有相同的含义。此外，每个线程都不必使用常用的 uintr_fd 注册自己。这将简化用户空间设置并有效利用内核内存。潜在的缺点是内核实现分配、修改、扩展和释放 UITT 将更加复杂。 + +对于一组彼此之间进行大量 IPC 的进程，也可以提出类似的论点。他们会更喜欢有一个共享的 UITT，让他们可以从任何进程针对任何进程。使用当前基于文件描述符的方法，连接设置可能会耗费时间并有些繁琐。我们需要评估是否可以使其更简单。 + +## 内核页面表隔离（KPTI） + +SENDUIPI 是一个特殊的 ring-3 指令，它对 UPID 和 UITT 内存进行了监管模式内存访问。当前的补丁需要禁用 KPTI 才能使用户 IPI 正常工作。要使用户 IPI 与 KPTI 正常工作，我们需要从具有监管访问但被映射到用户空间的特殊内存区域分配这些结构。计划实现类似于 LDT 的机制。 + +支持用户中断的处理器不受 Meltdown 影响，因此 KPTI 的自动模式将默认关闭。想要强制启用 KPTI 的用户需要等待这个补丁系列的后续版本才能使用用户中断。请告诉我们是否希望优先处理（或降低处理）这些补丁的开发。 + +# 常见问题解答 + +问：如果一个进程“意外”收到了用户中断会发生什么？ +答：对于没有向内核注册并请求用户中断的任务，不应该或无法接收到用户中断。 + +问：用户中断是否会影响内核调度？ +答：不会。如果一个任务被阻塞等待用户中断，当内核代表该任务接收到通知时，我们只会将其放回运行队列。用户中断的传递不会以任何方式改变任务的调度优先级。 + +问：发送方是否会知道中断是否已经被传递？ +答：不会。用户中断只提供了一种已发布的中断传递机制。如果应用程序需要依赖于中断是否已经传递，它们应该考虑使用用户空间机制进行反馈（如共享内存计数器或向发送方发送用户中断）。 + +问：为什么没有关于中断传递的反馈？ +答：由于是发布的中断传递机制，中断传递发生在两个步骤中： +1）中断信息存储在内存位置（UPID）中。 +2）物理中断传递给中断接收方。 + +第二步可能会立即发生，在延迟的一段时间后发生，或者可能永远不会发生，这取决于第一步后接收方的状态。（接收方可能已经禁用中断，在此期间被上下文切换出去，或者可能在此期间崩溃。）这使得硬件很难在执行SENDUIPI时可靠地提供反馈。 + +问：用户中断可以嵌套吗？ +答：可以。在中断处理程序中使用STUI指令将允许传递新的用户中断。但是，没有类似TPR（线程优先级寄存器）的机制，允许只能处理更高优先级的中断。当启用嵌套时，任何用户中断都可以被接受。 + +问：一个任务是否可以一次性接收所有待处理的用户中断？ +答：不行。硬件只允许一次处理一个向量。如果一个任务对待处理的所有中断感兴趣，那么我们可以添加一个系统调用来提供待处理中断的信息。 + +问：进程需要绑定到CPU上吗？ +答：不需要。用户中断将正确路由到接收方运行的任何CPU上。在上下文切换期间，内核会更新UPID中的CPU信息。 + +问：为什么UPID和UITT由内核分配？ +答：如果由用户空间分配，应用程序可能会滥用UPID和UITT来写入未授权的内存，并在任何CPU上生成中断。UPID和UITT由内核分配，并通过特权级访问硬件。 + +# 此系列的补丁结构 + +-
