    This Month in Rust OSDev (April 2020)

    + +

    Welcome to the first issue of "This Month in Rust OSDev". In these posts, we will give a regular overview of notable changes in the Rust operating system development community.

    + +

    These posts are the successor of the "Status Update" posts on the "Writing an OS in Rust" blog. Instead of only focusing on the updates to the blog and the directly related crates, we try to give an overview of the full Rust OSDev ecosystem in this new series. This includes all the projects under the rust-osdev GitHub organization, relevant projects of other organizations, and also personal OS projects.

    +

    This series is openly developed on GitHub. Feel free to open pull requests there with content you would like to see in the next issue. If you find some issues on this page, please report them by creating an issue.

    +

    News and Blog Posts

    +

    We try to collect posts that are relevant to Rust-based OS development each month. Please create pull requests for any posts that you want linked in the next issue.

    + +

    Project Updates

    +

    In this section, we give an overview of notable changes to the projects hosted under the rust-osdev organization.

    +

    x86_64

    +

    The x86_64 crate provides various abstractions for x86_64 systems, including wrappers for CPU instructions, access to processor-specific registers, and abstraction types for architecture-specific structures such as page tables and descriptor tables.

    +

    This month, we released version 0.10.0 of x86_64, which includes some breaking changes:

    + +

    After v0.10.0, the following changes were merged:

    + +

    Thanks to @m-ou-se, @tomaka, @haraldh, and @imtsuki for their contributions!

    +

    acpi and aml

    +

    The acpi repository contains crates for parsing the ACPI tables – data structures that the firmware of modern computers use to relay information about the hardware to the OS. The crate for parsing the static tables (acpi) was stabilised this month – while it needs more work to support the entire spec, it is now in the state where it can be integrated into a Rust kernel to provide useful information, and its overall architecture is unlikely to change in the near future.

    +

    The full set of changes is:

    + +

    Thanks to @tomaka for their contribution and congratulations to the creator and maintainer @IsaacWoods on the 1.0 release!

    +

    bootloader

    +

    The bootloader crate implements a custom Rust-based bootloader for easy loading of 64-bit ELF executables. It received the following updates this month:

    + +

    Thanks to @Freax13 and @realKennyStrawn93 for these changes!

    +

    Right now, @rybot666 and @phil-opp are working on a rewrite of the bootloader. The goal is to port the 16-bit and 32-bit stages from assembly to Rust, which should make the crate safer, more composable, and easier to understand for outsiders. Our progress is tracked in the Rewrite milestone.

    +

    bootimage

    +

    The bootimage tool allows the creation of bootable disk images for bootloader-based kernels. It also provides a runner executable for cargo to make cargo xrun and cargo xtest work using QEMU. In April, the crate received the following updates:

    + +

    Thanks to @Freax13 for their contribution!

    +

    uart_16550

    +

    The uart_16550 crate provides basic support for serial port I/O for 16550-compatible UARTs. This month, the crate received support for serial input:

    + +

    Thanks to @imtsuki for their contribution!

    +

    cargo-xbuild

    +

    The cargo-xbuild project provides cargo command wrappers to cross-compile the sysroot crates core and alloc. This month, we added a new environment variable to help debugging build errors:

    + +

    uefi

    +

    The uefi crate provides abstractions for the UEFI standard that replaces the traditional BIOS on modern systems. This month, the crate received a new cargo feature to ignore logger errors:

    + +

    New Projects

    +

    There are a number of new projects in the rust-osdev organization:

    +
      +
    • +

      homepage: As you might have noticed by now, we have a new organization-level homepage at https://rust-osdev.com/. The homepage repository contains the source code for this website. Right now, it is still a work-in-progress and only contains the very minimum to host this post, but we plan to add more content soon.

      +

      Note that we will create a branch for the upcoming May issue of "This Month in Rust OSDev". Please open pull requests for any content that you would like to see next month.

      +
      • +
    • +

      vga: The goal of the vga crate is to allow configuration of the VGA hardware. It already makes it possible to switch from a text-based buffer to a pixel-based framebuffer, which enables drawing of lines, geometric shapes, and even images. The library is created by @RKennedy9064.

      +
      • +
    • +

      ps2-mouse: The library provides a basic interface for interacting with a PS/2 mouse. It is also created by @RKennedy9064.

      +
      • +
    +

    Personal Projects

    +

    In this section, we describe updates to personal projects that are not directly related to the rust-osdev organization. Feel free to create a pull request with the updates of your OS project for the next post.

    +

    IsaacWoods/pebble

    +

    (Section written by @IsaacWoods)

    +

    Pebble has been undergoing a bit of a reorganisation, in the interests of supporting a second architecture (ARM64). A hardware abstraction layer (HAL) has been introduced that abstracts away the platform-specifics of managing page tables, creating processes etc. so that the main kernel crate is now completely platform-independent.

    +

    I also wrote a little TFTP server for netbooting a Raspberry Pi 4 from a development machine. This makes iterating the kernel a lot easier because there's no need to write it to an SD card after every compile. In the next few weeks, I hope to clean this code up and publish it for use as both a library and CLI application, and maybe write a blog-post on the intricacies of netbooting the Pi.

    +

    rust-embedded/rust-raspberrypi-OS-tutorials

    +

    (Section written by @andre-richter)

    +

    The Operating System development tutorials in Rust on the Raspberry Pi project received the following updates recently:

    +
      +
    • Add tutorial 14: Exceptions Part 2: Peripheral IRQs. +
        +
      • We write device drivers for the two interrupt controllers on the Raspberry Pi 3 (Broadcom +custom controller) and Pi 4 (ARM Generic Interrupt Controller v2, GICv2).
        • +
      • Modularity is ensured by interfacing everything through a trait named IRQManager.
        • +
      • Handling for our first peripheral IRQ is implemented: The UART's receive IRQ - one IRQ per +received character.
        • +
      +
      • +
    • Set chainloader relocation address to 32 MiB. +
        +
      • Enables booting on Pi3 A+ devices.
        • +
      +
      • +
    • Run the chainloader natively on non-Linux Unix systems. +
        +
      • Adds experimental support for macOS and other Unix systems which have Ruby available.
        • +
      +
      • +
    +

    phil-opp/blog_os

    +

    (Section written by @phil-opp)

    +

    Apart from a few minor fixes (thanks for all the contributions!), April was a quiet month for the "Writing an OS in Rust" project. I focused my work this month on the x86_64 library, the rewrite of the bootloader, and my job search instead. In this regard, I'm excited to announce that I have decided to do Rust-related freelance work for now, which will allow me to continue dedicating some of my time to open-source work.

    Welcome to the first issue of "This Month in Rust OSDev". In these posts, we will give a regular overview of notable changes in the Rust operating system development community.

    These posts are the successor of the "Status Update" posts on the "Writing an OS in Rust" blog. Instead of only focusing on the updates to the blog and the directly related crates, we try to give an overview of the full Rust OSDev ecosystem in this new series. This includes all the projects under the rust-osdev GitHub organization, relevant projects of other organizations, and also personal OS projects.

    This Month in Rust OSDev (May 2020)

    + + Written by + @phil-opp, @IsaacWoods, @GabrielMajeri, @stlankes, and @andre-richter + +
    Published on +     + +

    Welcome to the second issue of "This Month in Rust OSDev". In these posts, we will give a regular overview of notable changes in the Rust operating system development ecosystem.

    + +

    This series is openly developed on GitHub. Feel free to open pull requests there with content you would like to see in the next issue. If you find some issues on this page, please report them by creating an issue.

    + + +

    Project Updates

    +

    In this section, we give an overview of notable changes to the projects hosted under the rust-osdev organization.

    +

    x86_64

    +

    The x86_64 crate provides various abstractions for x86_64 systems, including wrappers for CPU instructions, access to processor-specific registers, and abstraction types for architecture-specific structures such as page tables and descriptor tables.

    +

    In May, the crate received a bugfix for inclusive page/frame ranges. We also landed a long-awaited change to the Mapper::map_to function to set certain page table flags also in higher level page tables:

    + +

    Thanks to @haraldh and @mrll for their contributions!

    +

    cargo-xbuild

    +

    The cargo-xbuild project provides cargo command wrappers to cross-compile the sysroot crates core and alloc.

    +

    This month, rustc/cargo changed their codegen behavior for builds with link-time optimization (LTO), which lead to breakage for LTO builds with cargo-xbuild. Fixing this issue was not easy and required multiple tries until we found a proper solution.

    +

    Unfortunately, the solution still led to link issues for some people, which was caused by a bug in cargo/rustc. Thanks to @alexcrichton, this was quickly fixed in rustc, so that now everything should work again.

    +

    Apart from these bugfixes, there were also two other changes this month:

    + +

    Thanks to @Nils-TUD for their contribution and to all the people that helped investigating the build errors!

    +

    acpi

    +

    The acpi repository contains crates for parsing the ACPI tables – data structures that the firmware of modern +computers use to relay information about the hardware to the OS.

    +

    Not a lot happened this month, but preparations +were made to change how the AML namespace is stored on the heap, in order to avoid a lot of small heap allocations +for AML paths, and reduce the number of heap allocations overall. However, some more profiling infrastructure will +need to be built before starting this.

    +

    In preparation, a change to how DefNames are stored in the namespace was made, which avoids an extra heap +allocation per DefName, and also allows us to simplify some code around the aml crate.

    +

    bootloader

    +

    The bootloader crate implements a custom Rust-based bootloader for easy loading of 64-bit ELF executables. It received the following updates this month:

    + +

    Thanks to @mark-i-m and @Aaron1011 for their contributions!

    +

    bootimage

    +

    The bootimage tool allows the creation of bootable disk images for bootloader-based kernels. It also provides a runner executable for cargo to make cargo xrun and cargo xtest work using QEMU. In May, the crate was almost completely rewritten with a smaller API to make it more maintainable:

    + +

    uart_16550

    +

    The uart_16550 crate provides basic support for serial port I/O for 16550-compatible UARTs. This month, the crate received the following updates:

    + +

    Thanks to @dbeckwith for their contribution!

    +

    uefi

    +

    The uefi crate provides abstractions for the UEFI standard that replaces the traditional BIOS on modern systems. This month, the crate's dependencies were updated, and a bug was fixed in the graphics protocol:

    + +

    Thanks to @imtsuki and @BinaryTENSHi for their contributions!

    + +

    Personal Projects

    +

    In this section, we describe updates to personal projects that are not directly related to the rust-osdev organization. Feel free to create a pull request with the updates of your OS project for the next post.

    +

    IsaacWoods/pebble

    +

    (Section written by @IsaacWoods)

    +

    This month, I've been tracking down a bug in the kernel that causes usermode stacks to become corrupted on the +return of some system calls. While I've not found the root cause, I've taken this opportunity to add some more +debugging capabilities, which have found a number of other kernel bugs.

    +

    I also started working on the Rust implementation of Ptah, +the wire format for Pebble's message passing interface. It allows libraries to easily use Serde to +serialize and deserialize Rust types to and from the wire format. In the future, a compiler will be able to +generate bindings for Ptah for a number of different supported languages, which will allow tasks written in +different languages to communicate over Pebble Channels using idiomatic types.

    +

    RustyHermit

    +

    (Section written by @stlankes)

    +

    RustyHermit is a unikernel targeting a scalable and predictable runtime. Unikernel means, you bundle your application directly with the kernel library, so that it can run without any installed operating system. +This reduces image size and overhead, therefore, interesting applications include virtual machines and high-performance computing.

    +

    This month the integration of smoltcp has been improved and first support for virtio has been integrated. The integration in Rust's standard runtime is already in progress and clients can be developed with TcpStream. Server side applications will follow soon.

    +

    phil-opp/blog_os

    +

    (Section written by @phil-opp)

    +

    This month, support for the legacy asm! macro was removed from rustc. This lead to build errors for the Writing an OS in Rust project because some dependencies were still using the macro. To fix this, I landed a number of dependency updates:

    + +

    I also decided to change the design of the executor in the Async/Await post to simplify it:

    + +

    While I already started a draft on the next blog post about processes, I currently plan to look into adding UEFI support to the bootloader crate first. The reason is that UEFI support will require some fundamental changes to the blog because the VGA text buffer and the legacy PIC are not supported on UEFI. This is also relevant to the upcoming post about processes, since different designs would be possible if we used the APIC instead of the legacy PIC. It therefore makes most sense to me to sort this out first.

    +

    rust-embedded/rust-raspberrypi-OS-tutorials

    +

    (Section written by @andre-richter)

    +

    May was a quiet month for the project, since I am currently taking a little hiatus. I am planning to restart working on new content two or three months down the road.

    +

    Therefore, only some maintenance updates went in, e.g. bumping all dependency crates to versions that support the new llvm_asm! macros. Also, the :cn: chinese translations received updates/additions (main Readme; 00_before_we_start).

    + +

    Welcome to a new issue of "This Month in Rust OSDev". In these posts, we will give a regular overview of notable changes in the Rust operating system development ecosystem.

    + +

    This series is openly developed on GitHub. Feel free to open pull requests there with content you would like to see in the next issue. If you find some issues on this page, please report them by creating an issue.

    + +

    Project Updates

    +

    In this section, we give an overview of notable changes to the projects hosted under the rust-osdev organization.

    +

    x86_64

    +

    The x86_64 crate provides various abstractions for x86_64 systems, including wrappers for CPU instructions, access to processor-specific registers, and abstraction types for architecture-specific structures such as page tables and descriptor tables.

    +

    In June, the crate received some smaller improvements:

    + +

    Thanks to @samueltardieu and @leecannon for their contributions!

    +

    cargo-xbuild

    +

    The cargo-xbuild project provides cargo command wrappers to cross-compile the sysroot crates core and alloc. This month, support for the cargo-features manifest key was added and a deprecated dependency was replaced:

    + +

    Thanks to @eggyal and @Eijebong for these contributions!

    +

    bootloader

    +

    The bootloader crate implements a custom Rust-based bootloader for easy loading of 64-bit ELF executables. This month, we fixed a newly introduced Rust warning:

    + +

    Thanks to @Freax13 for this contribution!

    +

    While we do not have to report any news yet, we are still working on a rewrite of the crate in order to make it more robust (use Rust instead of assembly for boot stages) and composable (in order to add UEFI and multiboot2 support).

    +

    acpi

    +

    The acpi repository contains crates for parsing the ACPI tables – data structures that the firmware of modern computers use to relay information about the hardware to the OS. This month, the crate received two small improvements to the RSDP-related code:

    + +

    uefi

    +

    The uefi crate provides abstractions for the UEFI standard that replaces the traditional BIOS on modern systems. This month, the contribution docs were extended with information how to add new UEFI protocols:

    + +

    Personal Projects

    +

    In this section, we describe updates to personal projects that are not directly related to the rust-osdev organization. Feel free to create a pull request with the updates of your OS project for the next post.

    +

    phil-opp/blog_os

    +

    (Section written by @phil-opp)

    +

    In June, I pushed two small improvements to the blog_os repository and the Writing an OS in Rust blog:

    + +

    There were also lots of small contributions this month that fixed typos and dead links and updated the Chinese translation. Thanks a lot to all contributors!

      This Month in Rust OSDev: December 2022

      + + Published on (edited by + @phil-opp) + +

      Welcome to a new issue of "This Month in Rust OSDev". In these posts, we give a regular overview of notable changes in the Rust operating system development ecosystem.

      + +

      This series is openly developed on GitHub. Feel free to open pull requests there with content you would like to see in the next issue. If you find some issues on this page, please report them by creating an issue or using our comment form at the bottom of this page.

      + +

      Infrastructure and Tooling

      +

      In this section, we collect recent updates to rustc, cargo, and other tooling that are relevant to Rust OS development.

      + +

      Experimental feature gate proposal interoperable_abi

      +

      This Rust language proposal suggests to create a new extern "interop" ABI as a strict superset of the C ABI. +The goal of this new ABI is to "define a standard way to make calls across high-level languages, passing high-level data types, without dropping to the lowest common denominator of C". +For example, it will define a specific memory representation for strings, tuples, and common standard library types such as Option and Result.

      +

      This new ABI would be very useful for operating system development because there are often multiple executables that need to communicate with each other using a stable ABI. +For example, user-space programs communicate with the kernel using system calls, and with each other porgrams using different forms of inter-process communication. +With new extern "interop" ABI, these communication boundaries could use safe, higher-level types when both sides are written in Rust.

      +

      default_alloc_error_handler has been stabilized

      +

      On no_std targets, enabling alloc requires providing an OOM (out-of-memory) handler. The usual implementation of this handler just panics, but implementing the handler requires an unstable feature: alloc_error_handler. The newly-stabilized default_alloc_error_handler automatically provides an OOM handler that panics if no custom handler is implemented. This is an important step towards using some targets on the stable channel.

      +

      Maintained by @phil-opp, @josephlr, @Freax13, and @rybot666

      +

      The x86_64 crate provides various abstractions for x86_64 systems, including wrappers for CPU instructions, access to processor-specific registers, and abstraction types for architecture-specific structures such as page tables and descriptor tables.

      +

      We merged the following changes in December:

      + +

      Thanks to @TornaxO7 for their contribution!

      Other Projects

      +

      In this section, we describe updates to Rust OS projects that are not directly related to the rust-osdev organization. Feel free to create a pull request with the updates of your OS project for the next post.

      +

      Theseus OS

      +

      (Section written by Kevin Boos (@kevinaboos))

      +

      Theseus is a safe-language OS written from scratch in Rust that is in the midst of a shift from academic research to usability and legacy compatibility. +Theseus loads and links all components at runtime, and executes everything at a single privilege level in a single address space, relying on Rust safety for isolation and correctness.

      +

      As a fully open-source project, we welcome and encourage contributions from everyone!

      +

      Since our last update here a few months ago, we have worked on the following things:

      +
        +
      • Introduced dreadnought, a basic async executor that brings Rust's async/await syntax to Theseus +
          +
        • Usable by both applications and low-level kernel components
          • +
        • Integrated the concept of wakers with Theseus's native task subsystem
          • +
        • Currently, there is a 1-to-1 relationship between async dreadnought tasks and native Theseus tasks
          • +
        +
        • +
      • Rewrote our networking interface to offer better, simpler, and cleaner abstractions +
          +
        • It now supports the latest smoltcp version, 0.8
          • +
        +
        • +
      • Added support for booting Theseus on UEFI +
          +
        • Previously, Theseus could boot from only multiboot2-compliant bootloaders using legacy BIOS
          • +
        • UEFI on x86_64 now successfully boots after significant redesign of early bootstrap routines
          • +
        • New custom uefi_loader tool, loosely based on the rust-osdev org's bootloader project
          • +
        • Early graphical display for basic text printing is a work-in-progress
          • +
        • UEFI is required to boot Theseus on aarch64; this is also a work-in-progress
          • +
        +
        • +
      • Almost completed porting core subsystems to aarch64 +
          +
        • Bootstrap and logging over UART
          • +
        • Memory management: page table modification, arch-agnostic PTE flags and basic memory types, etc
          • +
        • Basic context switching and task bootstrap
          • +
        • SMP multicore, plus identification of CPU cores
          • +
        • Interrupt handling via GIC
          • +
        +
        • +
      • Redesigned the drivers for PS/2 controller, keyboard, and mouse in an intralingual manner that fully leverages Rust's strong type system.
        • +
      • Started implementing a brand new graphics stack and window manager, Porthole, from scratch +
          +
        • Added support for x86's Page Attribute Table, which allows Theseus to control the caching properties of individual memory pages
          • +
        • We now map graphics video memory as write-combining instead of cache-disabled, which significantly improves performance
          • +
        +
        • +
      • Redesigned task management to give arbitrary tasks fewer privileges +
          +
        • Two new types: JoinableTaskRef and ExitableTaskRef +
            +
          • JoinableTaskRef is similar to std::task::JoinHandle, but is fully safe +
              +
            • Ensures that a task can only be joined by the "parent" task that spawned it
              • +
            • Remove distinction between joining a task and obtaining its ExitValue
              • +
            • Automatically reaps "orphan" tasks that are no longer joinable
              • +
            +
            • +
          • ExitableTaskRef statically ensures that only a task itself can mark itself as exited +
              +
            • Now, a given task can no longer invalidly mark another arbitrary task as exited
              • +
            +
            • +
          +
          • +
        • Refactored scheduler and task switching to not hold any TaskRefs during a context switch +
            +
          • Ensures that exited tasks are dropped and cleaned up expediently
            • +
          +
          • +
        • Native ELF Thread-Local Storage (TLS) variables are used to store the current task +
            +
          • Accessing the current task is much faster, albeit slightly more complicated to initialize
            • +
          +
          • +
        +
        • +
      • Implemented a new shell called hull, plus new terminal, console, and TTY components +
          +
        • Theseus can now run headlessly, e.g., interactively over a serial port instead of via a graphical display.
          • +
        +
        • +
      • Removed usage of owning_ref, a crate with unsoundness, in favor of our own types: +
          +
        • BorrowedMappedPages<T>: a pseudo-self-referential type that allows persistent, efficient borrowing of a MappedPages memory region as a specific type T +
            +
          • Accepts a Mutability type parameter for either immutable (&T) or mutable (&mut T) borrowing
            • +
          • Sister type BorrowedSliceMappedPages also supports dynamically-sized slices, i.e., &[T] and &mut [T]
            • +
          • Much more efficient than owning_ref because MappedPages is always pinned in memory, avoiding the need for Box allocation
            • +
          +
          • +
        • dereffer: a new library crate that provides DerefsTo<T>, a generic wrapper type that allows the enclosed object T to be arbitrarily dereferenced to any inner type reachable from that object T +
            +
          • Supports much more arbitrary and complex deref functions than std::ops::Deref
            • +
          +
          • +
        +
        • +
      • Canonicalized the content of Theseus's x86_64-unknown-theseus target spec +
          +
        • Codegen flags are now moved into the target spec, making out-of-tree builds easier and more repeatable
          • +
        • Target specs are now ready to be upstreamed into rustc as built-in targets
          • +
        +
        • +
      • owned_borrowed_trait: a new library crate that abstracts over Owned values vs. Borrowed refs +
          +
        • Uses traits and marker types instead of the existing enum-based designs (like Cow)
          • +
        • Doesn't require Clone or care about any characteristics of the inner type T
          • +
        • Allows you to use generics and associated consts to conditionally branch based on whether an owned value or borrowed reference was passed into a function
          • +
        • Allows you to return a different (generic) type from a function based on whether an owned value or borrowed reference was passed in
          • +
        +

      +

      Aero is a new modern, experimental, unix-like operating system following the monolithic kernel design. Supporting modern PC features such as long mode, 5-level paging, and SMP (multicore), to name a few.

      +

      This month, Aero successfully managed to get mesa-demos and alacritty running.

      system calls, and with each other porgrams using different forms of inter-process communication. +For example, user-space programs communicate with the kernel using system calls, and with other programs using different forms of inter-process communication. With new extern "interop" ABI, these communication boundaries could use safe, higher-level types when both sides are written in Rust.

      default_alloc_error_handler has been stabilized

      On no_std targets, enabling alloc requires providing an OOM (out-of-memory) handler. The usual implementation of this handler just panics, but implementing the handler requires an unstable feature: alloc_error_handler. The newly-stabilized default_alloc_error_handler automatically provides an OOM handler that panics if no custom handler is implemented. This is an important step towards using some targets on the stable channel.

          Cargo: Add '-C' flag for changing current dir before build

          +

          This new flag makes cargo switch to the specified directory before building. +This means that the .cargo/config.toml file is also read from that directory, which can be very useful when configuring features such as build-std.

          multiboot2
          
+
          Maintained by @IsaacWoods, @phip1611, @robert-w-gries, @ahmedcharles, and @Caduser2020
          
+
          The multiboot2 crate provides abstraction types for the multiboot information
+structure (MBI) of multiboot2 bootloaders. The latest release of the
+multiboot2-crate is now v0.15.0 (was v0.14.0), which fixed a
+bug. Furthermore, the
+documentation was improved. However, the biggest change is that the library now
+allows the parsing of custom multiboot tags, which are not prohibited by the
+spec. For a full changelog, please refer to the
+GitHub repo.
          
+
          CI Refactoring
          
+
          In the CI, we want to run many tests that cover a big portion of the cartesian
+product of the following properties:
          
+
            
+
          • rust version: stable, nightly, msrv
            • 
+
          • type: build, test, style check
            • 
+
          • target: default, no_std
            • 
+
          
+
          As I (@phip1611) was annoyed by all the boilerplate configuration and
+repetition, I've investigated new ways to improve that situation and created
+a reusable workflow can be used like that:
          
+
          jobs:
+  build_msrv:
+    name: build (msrv)
+    uses: ./.github/workflows/_build-rust.yml
+    with:
+      rust-version: 1.56.1
+      do-style-check: false
+
+  style_nightly:
+    name: style (nightly)
+    needs: build_nightly
+    uses: ./.github/workflows/_build-rust.yml
+    with:
+      rust-version: nightly
+      do-style-check: true
+      do-test: false
+
          
+
          The ./.github/workflows/_build-rust.yml workflow abstracts setting up the
+toolchain, setting up a cargo cache for a faster CI, and, depending on the
+configuration, running cargo test|clippy|doc|build|fmt. I think that the
+outcome is quite nice and might also help others. Feel free to check out the
+corresponding PR.

            phip1611/paging-calculator
            
+
            (Section written by @phip1611)
            
+
            In the November newsletter, I announced the initial release of my
+paging-calculator CLI utility. Recently, I released a new version, which now
+covers page table indices for x86, x86 with physical address extension (PAE),
+x86_64, and x86_64 with 5 levels. For example, just type $ paging-calculator 0xdeadbeef x86
+and $ paging-calculator 0xdeadbeef x86 --paeand compare the result. You can
+install it from crates.io or with
+the pkgs.paging-calculator attribute,
+if you are a Nix user.

            xiaoyang-sde/rust-kernel-riscv
            
+
            (Section written by @xiaoyang-sde)
            
+
            rust-kernel-riscv is an experimental operating system kernel built using Rust's asynchronous programming model to schedule threads in both kernel and user space. This approach allows for more efficient context switching and eliminates the need for allocating a separate kernel stack for each user process. In its current iteration, the kernel provides a basic shell capable of running several executables that demonstrate various kernel mechanisms.
            
+
            The kernel provides a built-in executor, which manages the scheduling and execution of threads. Threads are executed for a time slice before an exception or interrupt occurs, and then the executor switches to another thread. To give you a better understanding, I included the async function that represents the lifetime of a user thread below, and I wrote a detailed design document.
            
+
            async fn thread_loop(thread: Arc<Thread>) {
+    loop {
+        let trap_context = thread.state().lock().user_trap_context_mut();
+        _enter_user_space(trap_context, thread.satp());
+
+        // Invokes related methods to handle the exception or interrupt,
+        // which returns a variant of the `ControlFlow` enum
+
+        match control_flow {
+            ControlFlow::Continue => continue,
+            ControlFlow::Yield => yield_now().await,
+            ControlFlow::Exit(exit_code) => {
+                thread.exit(exit_code);
+                break;
+            }
+        }
+    }
+}
+
            
+
            The idea behind rust-kernel-riscv was inspired by Phil's recent blog post on using async/await in the kernel. Thanks Phil for his invaluable support to the Rust community!

                  The volatile crate provides safe wrapper types for implementing volatile read and write operations. This month, we published version 0.4.0, which completely rewrites the crate based on reference values. Instead of wrapping the target value directly as e.g. Volatile<u32>, the new implementation works by wrapping reference types such as Volatile<&mut u32>. See our completely revamped documentation for more details.
                  
-
                  The main advantage of the new reference-based implementation is that it is now possible to work with volatile arrays and slices, at least on nightly Rust. Through the index and index_mut methods it is possible to create sub-slices, which can then be read and written efficiently through the copy_into_slice and copy_from_slice methods. All these operations perform volatile memory accesses, so that the compiler won't optimize them away.

                  volatile
                  
+
                  Maintained by @phil-opp
                  
+
                  The volatile crate provides a safe wrapper type for implementing volatile read and write operations. This is useful for accessing memory regions that have side-effects, such as memory-mapped hardware registers or framebuffers.
                  
+
                  Unfortunately, the design crate had a soundness issue because it used reference types for accessing the volatile memory. This is problematic because the Rust compiler marks references are "dereferencable", which allows LLVM to insert spurious read operations. This is fine for accessing "normal" memory, but it can lead to correctness issues when used in combination with memory-mapped device registers. These registers look like normal memory, but they are actually accessing some device-specific registers, which might change at any time. So they might change between spurious reads, which violates the assumptions of LLVM and can lead to undefined behavior.
                  
+
                  To solve this issue, we started a full redesign of the crate that uses raw pointers only. This solves the issue because raw pointers are not considered "dereferencable", so LLVM is not allowed to insert spurious reads. While we started working on the new design more than 2 years ago, we didn't merge it until this month because we weren't sure about the implementation details. The main discussion point was whether we should treat the proposed VolatilePointer type like Rust's reference types or like Rust's raw pointer types. The difference is that raw pointers implement the Copy trait, but are not Send to prevent aliasing. References, on the other hand, can safely implement Send because they're only Copy if the reference is read-only.
                  
+
                  After a lot of back and forth, we decided to provide both options and finally publish volatile v0.5. So the new design has two wrapper types, VolatilePtr (behaves like a raw pointer) and VolatileRef (behaves like a reference). We hope that we support most use cases this way!
                  
+
                  Note that there is also some ongoing discussion about a potential VolatileCell type to wrap values in-place. Most implementations of such a type would require support from the Rust compiler, which needs an RFC. However, there is one promising design based on zero-sized types and proc-macros by @Freax13 that should not require any new language features. We will continue to investigate.

                  The multiboot2 and the multiboot2-header
+crates got a big overhaul. The list of new features includes but is not limited to:

                  • add a runtime builder for an MBI (#133) 
                    
+Huge thanks to YtvwlD / Niklas for this greate external contribution
                    • 
+
                  • added an integration test including a multiboot2 chainloader for better test coverage (#129)
                    • 
+
                  • added miri to the CI for more memory safety (#128)
                    • 
+
                  • several fixes and small improvements
                    • 
+
                  
+
                  multiboot2 was updated from 0.15.1 to 0.16.0 and multiboot2-header was updated from 0.2.0 to 0.3.0. Both 
+releases come with a large amount of breaking changes. 
+However, after a sensible consideration, they are all worth it for a more streamlined API and more memory safety.

                    While the Hermit targets (x86_64-unknown-hermit and aarch64-unknown-hermit) are still at tier 3, we now distribute pre-built artifacts of the Rust standard library for use with stable toolchains!
+This means, no more -Zbuild-std, resulting in faster builds, and the bliss of the stable Rust compiler.

                      CLUU is a hobby operating system being written in Rust - in the active development phase - targeting x86_64 and with plans to support aarch64 in the future. The project is made for fun and joy, drawing inspiration from various operating systems and projects while incorporating unique approaches and ideas.

                      Motivation
                      
+
                      CLUU is driven by the motivation to explore operating system development in a powerful language like Rust. The project seeks to break away from the traditional approach using languages like C, which can sometimes feel limiting or mundane. With CLUU, the goal is to embark on a learning journey and have fun in the process. Contributions from the community are highly encouraged and welcomed.

+
                      • RedoxOS: RedoxOS is an operating system written in Rust, aiming to bring the innovations of Rust to a modern microkernel and full set of applications. It's fair to say it is the most advanced of all Rust OS-es.
                        • 
+
                      • k4dos: k4dos is another hobby-os of that sort, it's fairly cool, with userspace, that can run FreeDoom for example. It has a nice shell implementation: kash
                        • 
+
                      • blog_os: blog_os is a cutting-edge project by Philipp Oppermann that provides a detailed tutorial on building an operating system in Rust. It covers various aspects, including the bootloader, memory management, and device drivers.

                      CLUU aims to create a UNIX-like operating system, although not plannig to fully adhere to the POSIX standards. The goal is to get as close to the UNIX philosophy and compatibility as possible. This would enable easier porting of Linux software to CLUU and provide a familiar environment for developers.
                      
+
                      Current State and Goals
                      
+
                      CLUU is currently in the early stages of development, with the focus on building a solid foundation for the operating system. At this stage, the following basic functionalities have been implemented:
                      
+
                        
+
                      • UART16550 driver: A driver for UART16550, allowing communication with the serial port for debugging and logging purposes.
                        • 
+
                      • Preparation for PIO and MMIO: The groundwork has been laid for implementing both Programmed I/O (PIO) and Memory-Mapped I/O (MMIO) for interacting with hardware devices.
                        • 
+
                      • Framebuffer driver: A driver for the framebuffer, providing a graphical output display.
                        • 
+
                      • Simple graphics and writing: Basic graphical capabilities have been implemented, allowing for drawing and writing on the screen using a PSF font.
                        • 
+
                      • Basic Logging framework: A basic logging framework has been developed to facilitate debugging and information output during the development process.
                        • 
+
                      
+
                      Screencheck serial_output
                      
+
                      As the project progresses, the focus will shift towards implementing additional features, such as:
                      
+
                        
+
                      • Kernel Implementation: Further development of the microkernel's core functionality, including process management, interprocess communication, and resource management.
                        • 
+
                      • Device Drivers: Continued development of drivers for essential hardware components, including keyboard, storage devices, and other peripherals.
                        • 
+
                      • Filesystem Support: Introducing filesystem support to enable file I/O operations and provide a foundation for user-level processes and applications.
                        • 
+

                  RustyHermit is a unikernel, which is completely written Rust. Unikernels are application images that directly contain the kernel as a library, so they do not require an installed operating system (OS). They are typical used in virtualized environments, which build the backbone of typical cloud / edge infrastructures.

                  volatil
 
                  After a lot of back and forth, we decided to provide both options and finally publish volatile v0.5. So the new design has two wrapper types, VolatilePtr (behaves like a raw pointer) and VolatileRef (behaves like a reference). We hope that we support most use cases this way!
                  
 
                  Note that there is also some ongoing discussion about a potential VolatileCell type to wrap values in-place. Most implementations of such a type would require support from the Rust compiler, which needs an RFC. However, there is one promising design based on zero-sized types and proc-macros by @Freax13 that should not require any new language features. We will continue to investigate.

                    The multiboot2 was bumped from 0.16.0 
+to 0.17.0. The new release includes the builder pattern for the MBI builder 
+and the ability to use custom memory types in the memory map in addition to 
+pre-defined ones. For more info, look here.

                    SFBdragon/talc
                    
+
                    (Section written by @SFBdragon)
                    
+
                    Talc is a recently published, fast, and flexible no-std memory allocator. 
                    
+
                      
+
                    • It's the fastest allocator I've tested as of yet (galloc falls short, buddy_alloc is close but lacks heap efficiency).
                      • 
+
                    • It features a OOM-handling component with dynamic arena resizing.
                      • 
+
                    
+
                    By the time you're seeing this, hopefully v2 should be out or coming soon:
                    
+
                      
+
                    • The OOM handler system has been made more powerful.
                      • 
+
                    • lock_api is used to allow for custom allocator synchronization.
                      • 
+
                    • The internals and API has been improved to pass miri's stacked borrows validation.
                      • 
+
                    • You can now move the allocator struct around freely.
                      • 
+
                    • And more :3
                      • 
+
                    
+
                    I hope you find it useful!

+
                    (Section written by @vinc)
                    
+
                    MOROS is a text-based hobby operating system targeting computers with a x86-64 architecture and a BIOS.
                    
+
                    Since last month's release, I focused on adding new syscalls to interact with network sockets from userspace. The DNS and HTTP clients are now using the new UDP and TCP sockets.
                    
+
                    I also added another syscall to poll multiple handles at the same time, to read from the console and a socket, improving the main network tool that can now be used as a simple chat program.
                    
+
                    The VGA driver, the filesystem, and the editor got a few significant improvements as well, to support downloading and reading larger files.

                    Hermit is a unikernel project, that is completely written in Rust.
+Unikernels are application images that directly contain the kernel as a library, so they do not require an installed operating system (OS).
+They are typically used in virtualized environments, which build the backbone of typical cloud and edge infrastructures.
                    
+
+
+
+
                    Virtualization Designs
                    
+
                    Common virtualized environments are based on classical virtual machines.
+In this case, complete machines are emulated or virtualized, and common operating systems are running on both the host and guest sides:
                    
+
                    Structure of a common virtualization environment
                    
+
                    This technique is established (VMware, Hyper-V, etc.) and widely used.
+However, it introduces additional overhead, especially regarding memory consumption and performance.
                    
+
                    An alternative approach to common virtual machines is OS-level virtualization, where the kernel allows the existence of multiple isolated user-space instances.
+These isolated instances are also known as “containers.”
+Typical representatives are LXC and Docker, which promise less overhead in comparison to common virtual machines.
+However, the isolation between the processes is weaker and may provide less security.
                    
+
                    Unikernels
                    
+
                    Often, only one application (e.g., a web server) is running in the container or the virtual machine.
+In this case, a unikernel is an attractive solution.
+The kernel is provided as a static library and linked to the application.
+As the images directly contain the OS kernel, unikernels can be directly booted inside a virtual machine and do not require the typical software stack containing a Linux kernel and its user land within the VM.
                    
+
                    Unikernels do not provide system calls in the classical sense, as everything is running with the privilege level of a kernel, and what is typically done via system calls is provided via a common function call.
+At first glance, this sounds more insecure than previous approaches.
+However, these kernels are expected to run within a virtual machine, which isolates the application from the real system.
+In addition, common compiler analysis is used to check the complete software stack, and unneeded components can even be removed, which can reduce the attack surface of the application.
                    
+
                    Structure of a library operating system
                    
+
                    Well-known unikernels are kernels such as MirageOS and Unikraft.
+MirageOS is written in OCaml, while Unikraft still uses C as the programming language of choice.
+In contrast to these kernels, Hermit is completely written in Rust to benefit from Rust's performance and security behavior.
                    
+
                    Hermit
                    
+
                    In principle, every existing Rust application can be built on top of Hermit.
+However, unikernels are single-tasking operating systems.
+Consequently, support for the system call fork and inter-process communication is missing.
+In addition, a classical C library is missing, which is typically used as an interface to the operating system.
+Every crate that bypasses the standard runtime and tries to communicate directly with the operating system does not work without modifications.
+However, many applications do not depend on these features and work on Hermit.
                    
+
                    Performance
                    
+
                    Unikernels can be highly optimized.
+For instance, we optimized the network stack of Hermit.
+Hermit uses smoltcp as the network stack, which is completely written in Rust.
+As the interface between the guest and host operating systems, we use virtio, which is a para-virtualized driver for KVM and widely used in virtualized Linux environments.
                    
+
                    The following figure compares Linux with Hermit, where both are running as guests inside a virtual machine running on top of a Linux-based host system:
                    
+
                    Bandwidth of the Hermit's experimental network interface
                    
+
                    Especially for small messages, Hermit is faster than Linux.
                    
+
                    Research
                    
+
                    Hermit is also a research project to evaluate new operating system designs, that improve the scalability and security of operating systems in cloud environments.
+For instance, Hermit provides classical techniques to improve security behavior, like stack guards and separating the application stack from the libOS stack.
+However, a library operating system typically uses a common function call to enter the kernel.
+A classical separation of user and kernel space by entering a higher privilege level is missing.
                    
+
                    In a paper, we presented a modified version of Hermit, which provides intra-unikernel isolation with Intel Memory Protection Keys (MPK).
+MPK is a relatively new hardware primitive that provides per-thread permission control over groups of pages in a single address space with negligible switching overhead, making it a compelling candidate for use in unikernels.
                    
+
                    MPK requires modification of page tables at a small performance cost.
+Four previously unused bits of each page table entry (the 62nd to the 59th on x86-64) are exploited by MPK.
+Since MPK exploits four bits of the page table entry, it supports up to 15 protection keys.
+MPK controls per-thread permission on groups of pages.
+Each core has a PKRU register (32 bits) containing a permission value.
+The value of the PKRU register defines the permission of the thread currently running on that core for each group of pages containing a protection key in their page table entries.
+Unlike page-table-level permission, MPK provides thread-local memory permission.
                    
+
                    We provide user and kernel separation, so we simply see the entire application as an untrusted component, independently of application-specific characteristics such as the language it is written in or the level of skill of the application’s programmer.
+In addition, we divide the kernel code into trusted and untrusted components.
+Trusted kernel components represent pieces of code written in a memory-safe language, i.e., offering strong security guarantees.
+Untrusted kernel components correspond to code written either in memory-unsafe languages or in unsafe Rust code blocks.
                    
+
                    By entering the library operating system through the application binary interface, the protection keys will be automatically changed, which allows access to the kernel stack and the kernel heap.
+Unauthorized access from within the application will trigger a page fault, which will be handled by the library operating system.
                    
+
                    Getting Started
                    
+
                    Take a look at hermit-os/hermit-rs-template for a simple starter application.
                    
+
                    The Hermit platform is an official Rust target.
+You can either use our prebuilt rust-std artifacts on stable Rust or use build-std on nightly Rust.
+Alternatively, you can compile the whole Rust compiler for Hermit, of course.
                    
+
                    Roadmap
                    
+
                    In the near future, we plan to stabilize the interface to the hardware.
+For instance, the support of virtiofs is at an early stage.
+In addition, the integration into the Rust standard library isn't finalized yet, and the current version runs only on x86-64.
+In the future, we want to also support AArch64 as a processor architecture.

                  RustyHermit is a unikernel, which is completely written Rust. Unikernels are application images that directly contain the kernel as a library, so they do not require an installed operating system (OS). They are typical used in virtualized environments, which build the backbone of typical cloud / edge infrastructures.

                  Virtualization Designs
                  
-
                  Common virtualized environments are based on classical virtual machines. In this case, complete machines are emulated or virtualized and common operating systems are running on both host and guest site:

                  Structure of a common virtualitation environment
                  
-
                  This technique is established (VMware, Hyper-V, etc.) and widely used. However, it introduces additional overhead especially regarding memory consumption and performance.
                  
-
                  An alternative approach to common virtual machines is OS-level
-virtualization, where the kernel allows the existence of multiple
-isolated user space instances. These isolated instances are also known
-as container. A typical representative is LXC or Docker and promise less
-overhead in comparison to common virtual machines. However, the
-isolation between the processes is weaker and may provide less security.
                  
-
                  Unikernels
                  
-
                  Often only one application (e.g. a web server) is running in the container or the virtual machine. In this case, a unikernel is an attractive solution. The kernel is provided as static library and linked to the application. As the images directly contain the OS kernel, unikernels can directly be booted inside a virtual machine and do not require the typical software stack containing a Linux kernel and its userland within the VM.
                  
-
                  Unikernels do not provide system calls in the classical sense, as everything is running with the privilege level of a kernel and what is typically done via system calls is provided via a common function call. At first glance, this sounds more insecure than previous approaches. However, these kernels are expected to run within a virtual machine, which isolates the application from the real system. In addition, common compiler analysis is used to check the complete software stack and unneeded components can even be removed, which can reduce the attack surface of the application.

                  Structure of a library operating system
                  
-
                  Well known unikernels are kernels such as MirageOS
-and Unikraft. MirageOS is written in OCaml,
-while Unikraft still uses C as programming language. In contrast to these
-kernels, RustyHermit is completely written in Rust to benefit from
-Rust's performance and security behavior.

                  RustyHermit
                  
-
                  In principle, every existing
-Rust application can be built on top of RustyHermit. However, unikernels
-are a single tasking operating system. Consequently, the support of the
-system call fork and inter-process communication are missing. In
-addition, a classical C library is missing, which is typical used as
-interface to the operating system. Every crate, which bypasses the
-standard runtime and tries to communicate directly to operating system
-does not work without modifications. However, many applications do not
-depend on these features and work on RustyHermit.
                  
-
                  Performance
                  
-
                  Unikernels can be highly optimized. For instance, we optimized the
-network stack of RustyHermit. RustyHermit uses
-smoltcp as network stack, which
-is completely written in Rust. As interface between guest and host
-operating system, we use
-Virtio, which is in a
-para-virtualized driver for KVM and widely used in virtualized Linux
-environments.
                  
-
                  The following figure compares Linux with RustyHermit,
-where both are running as guests inside a virtual machine running on top
-of a Linux-based host system:

                  Bandwidth of the RustyHermit's exerimental network interface

                  Especially for small messages RustHermit
-is faster in than Linux.

-
                  RustyHermit is also a research project to evaluate new operating
-system designs, which improves the scalability and the security of operating systems in cloud environments. For instance, RustyHermit provides classical
-techniques to improve the security behavior like stack guards and
-separating the application stack from the libOS stack. However, a
-library operating system typically uses a common function call to enter
-the kernel. A classical separation of user- and kernel space by
-entering a higher privilege level is missing.
                  
-
                  We presented in a
-paper a modified
-version of RustyHermit, which provides an intra-unikernel isolation with
-Intel Memory Protection Keys (MPK). MPK is a relatively new hardware
-primitive that provides per-thread permission control over groups of
-pages in a single address space with negligible switching overhead,
-making it a compelling candidate for use in unikernels.
                  
-
                  MPK is requiring modification of page tables at a small performance cost. Four previously-unused bits of each page table entry (the 62nd to the 59th on x86-64) are exploited by MPK. Since MPK exploits four bits of the page table entry, it supports up to 15 protection keys.
-MPK controls per-thread permission on groups of pages. Each core has a PKRU register (32 bits) containing a permission value. The value of the PKRU register defines the permission of the thread currently running on that core for each group of pages containing a protection key in their page table entries. Unlike page-table-level permission, MPK provides thread-local memory permission.
                  
-
                  We provide user / kernel separation so we simply see the entire application as an untrusted component, independently of application-specific characteristics such as the language it is written in or the level of skill of the application’s programmer. In addition, we divide the kernel code into trusted and untrusted components. Trusted kernel components represent pieces of code written with a memory-safe language, i.e., offering strong security guarantees. Untrusted kernel components correspond to code written either in memory-unsafe languages or in unsafe Rust code blocks.
                  
-
                  By entering the library operating system through the application binary interface the protection keys will be automatically changed, which allows access to the kernel stack and the kernel heap. Unauthorized access from within the application will trigger a pagefault, which will be handled by the library operating system.

                  Example Project
                  
-
                  To give you an example on how to build an RustyHermit application, lets create a new cargo project:
                  
-
                  cargo new hello_world
-cd hello_world
-
                  
-
                  RustyHermit currently requires the nightly versions of the Rust toolchain.
-To simplify the workflow, we recommend to create the configuration
-rust-toolchain as follows to define the required components and to
-tested version of nightly compiler:
                  
-
                  [toolchain]
-channel = "nightly-2020-12-23"
-components = [ "rustfmt", "rust-src", "llvm-tools-preview"]
-targets = [ "x86_64-unknown-hermit" ]
-
                  
-
                  The configuration file specifies the required components and the version of the nightly compiler to use.
                  
-
                  The RustyHermit's target x86_64-unknown-hermit is part of Rust
-supported platforms, but doesn't belong to the tier 1 platforms,
-which means that official binary releases aren't available and the
-standard runtime must be build from scratch.
-To simplify this build process, we recommend to create the configuration
-file .cargo/config as follows:
                  
-
                  [unstable]
-build-std = ["std", "core", "alloc", "panic_abort"]
-
-[build]
-target = "x86_64-unknown-hermit"
-
                  
-
                  To bind the library operating system to the application, we have to add the crate hermit-sys to the dependencies in the file Cargo.toml:
                  
-
                  # Cargo.toml
-
-[target.'cfg(target_os = "hermit")'.dependencies]
-hermit-sys = "0.1.*"
-features = ["smoltcp"]
-
                  
-
                  The feature smoltcp is required if your application tries
-to establish a TCP connection. In this case, the library operating systems
-includes the TCP/stack smoltcp.
-In addition hermit-sys depends on the tool cargo-download to download required components and must be installed with the command cargo install cargo-download.
-Finally, the application can be build with the common command cargo build.
                  
-
                  The result is a 64-bit excutable in the executable link format (ELF).
-To start the application within a common virtual machine, a loader is required, which initialize the processor and start the applications.
-We provide a simple loader on GitHub.
-A makefile to build the loader is part of the project.
-After that, Qemu can be used to start RustyHermit in a VM as follows:
                  
-
                  qemu-system-x86_64 -display none -smp 1 -m 64M -serial stdio  -kernel path_to_loader/rusty-loader -initrd path_to_app/app -cpu qemu64,apic,fsgsbase,rdtscp,xsave,fxsr
-
                  
-
                  To improve the performance, KVM can be used to use the virtualization extension of modern processors.
                  
-
                  qemu-system-x86_64 -display none -smp 1 -m 64M -serial stdio  -kernel path_to_loader/rusty-loader -initrd path_to_hello_world/hello_world -enable-kvm -cpu host
-
                  
-
                  Roadmap
                  
-
                  For the near future, we plan to stabilize the interface to the hardware.
-For instance, the support of Virtio-fs
-is in an early stage. In addition, the integration into Rust standard
-library isn't finalized yet and the current version runs only on x86. In the
-future, we want to also support aarch64 as processor architecture.

                  mkroening/take-static
                  
+
                  (Section written by @mkroening)
                  
+
                  I published a tiny new crate, allowing you to get a mutable reference to static items safely (only once, though):
                  
+
                  use take_static::take_static;
+
+take_static! {
+    static NUMBER: usize = 5;
+}
+
+assert_eq!(NUMBER.take(), Some(&mut 5));
+assert_eq!(NUMBER.take(), None);
+
                  
+
                  This allows you to easily use statically allocated memory before dynamic memory allocators may be available.
+Compared to cortex_m::singleton, take_static is thread-safe.
+Compared to takecell::TakeCell, take_static also supports !Send types.

                  The Hermit unikernel project allows you to bundle your Rust application with our library operating system to create a bootable unikernel image.
+Hermit is a single-address-space operating system.
+Since there is only one application running in the virtual machine, no isolation between applications or between user space and kernel space is necessary.
+This reduces system call overhead immensely, since every system call is just a library call.
+For more information, see our The Hermit Operating System showcase post.
                  
+
                  The RustyHermit project has been renamed.
+We have renamed our GitHub organization from @hermitcore to @hermit-os and reserved the http://hermit-os.org domain.
                  
+
                  We have also renamed some of our core projects to reduce confusion:
                  
+
+
                  We have a new logo!
+As hermit crabs occupy empty shells produced by other organisms, the original HermitCore occupied one or several cores on a computer.
+Because we migrated to Rust in 2018, our new logo of a hermit crab occupying the Rust logo's bike gear fits quite nicely with the Rust logo as well as Rust's Ferris.
                  
+
                  And as always, please come and try Hermit! :)

                    The bootloader crate implements a custom Rust-based bootloader for easy loading of 64-bit ELF executables. This month, we published versions 0.9.9 to 0.9.11 to fix build errors on the latest nightlies, caused by the new feature gate names for some const fn features.

                    We also made some more progress on the rewrite with UEFI support. It now passes additional framebuffer information and the address of the RSDP structure of ACPI in the boot info. (We later updated the RSDP code to use the new rsdp crate). The bootloader also gained support for setting up a recursive page table mapping, which makes it almost feature-equivalent with the current implementation. There are still a few things missings, but it should be ready to be published soon.

            volatile
            
 
            Maintained by @phil-opp
            
 
            The volatile crate provides a safe wrapper type for implementing volatile read and write operations. This is useful for accessing memory regions that have side-effects, such as memory-mapped hardware registers or framebuffers.
            
-
            Unfortunately, the design crate had a soundness issue because it used reference types for accessing the volatile memory. This is problematic because the Rust compiler marks references are "dereferencable", which allows LLVM to insert spurious read operations. This is fine for accessing "normal" memory, but it can lead to correctness issues when used in combination with memory-mapped device registers. These registers look like normal memory, but they are actually accessing some device-specific registers, which might change at any time. So they might change between spurious reads, which violates the assumptions of LLVM and can lead to undefined behavior.
            
-
            To solve this issue, we started a full redesign of the crate that uses raw pointers only. This solves the issue because raw pointers are not considered "dereferencable", so LLVM is not allowed to insert spurious reads. While we started working on the new design more than 2 years ago, we didn't merge it until this month because we weren't sure about the implementation details. The main discussion point was whether we should treat the proposed VolatilePointer type like Rust's reference types or like Rust's raw pointer types. The difference is that raw pointers implement the Copy trait, but are not Send to prevent aliasing. References, on the other hand, can safely implement Send because they're only Copy if the reference is read-only.

            After a lot of back and forth, we decided to provide both options and finally publish volatile v0.5. So the new design has two wrapper types, VolatilePtr (behaves like a raw pointer) and VolatileRef (behaves like a reference). We hope that we support most use cases this way!
            
 
            Note that there is also some ongoing discussion about a potential VolatileCell type to wrap values in-place. Most implementations of such a type would require support from the Rust compiler, which needs an RFC. However, there is one promising design based on zero-sized types and proc-macros by @Freax13 that should not require any new language features. We will continue to investigate.

+
            The multiboot2 was bumped from 0.18.1 
+to 0.19.0. The new release includes the ability to add custom tags to the MBI 
+builder and a bugfix when parsing Multiboot strings, such as the command line 
+from a Module tag.
            
+
            For more details, please have a look at the changelog.

            acpi
            
+
            Maintained by @IsaacWoods
            
+
            The acpi repository contains crates for parsing the ACPI tables – data structures that the firmware of modern computers use to relay information about the hardware to the OS.
            
+
            This month, a new major version of acpi was published, offering greater control over how the crate allocates
+memory. Specifically, the new allocator_api and alloc features allow you to opt-out of allocation altogether
+(allowing the crate to be used from slimmer environments like bootloaders), or to provide your own allocator using
+the new (and still unstable) core::alloc::Allocator API.
+Enabling both features makes the crate behave very similarly to before, so migration should be relatively easy.
            
+
            Because the acpi crate can now be used from environements without allocation, the rsdp crate has been
+deprecated, and all functionality moved into acpi. The rsdp crate will continue to work, but will not receive
+further updates. This should not affect users using rsdp to simply find the address of the RSDP, but is a
+breaking change as types that have been moved to acpi will no longer be usable across the crate boundary.
            
+
            Some improvements were also made to the aml crate this month, adding functionality and improving our correctness

            mkroening/interrupts
            
+
            (Section written by @mkroening)
            
+
            I created a dependency-free interrupts crate, allowing you to temporarily disable interrupts on AArch64, 64-bit RISC-V, and x86-64.
+Two different paradigms allow you to run code without interrupts and synchronize with interrupt handlers running on the same hardware thread (core):
            
+
            Use disable to disable interrupts with a guard:
            
+
            // interrupts may or may not be enabled
+let guard = interrupts::disable();
+// interrupts are disabled
+drop(guard);
+// interrupts are restored to the previous state
+
            
+
            Use without (similar to x86_64::instructions::interrupts::without_interrupts) to run a closure with disabled interrupts:
            
+
            // interrupts may or may not be enabled
+interrupts::without(|| {
+    // interrupts are disabled
+});
+// interrupts are restored to the previous state
+
            
+
            I would appreciate you dropping by and giving it a try. :)

            RavnOS

            +

            RanvOS, (from norwegian; raven), is a operative system programmed in Rust. Aims to be; minimal, stable, secure and modern ( this maybe you know as; state-of-art ).

            +

            The objective of RavnOS is make an operative system minimalist, self hosted (no external crates, all programmed by me), stable and secure.

            mkroening/interrupt-mutex

            +

            (Section written by @mkroening)

            +

            Building upon last month's interrupts crate, I created a mutex for sharing data with interrupt handlers or signal handlers.

            +

            RawInterruptMutex wraps any lock_api::RawMutex, be it a parking_lot::RawMutex on Unix or a spinning_top::RawSpinlock on bare metal. +When such an InterruptMutex is locked, interrupts are disabled. +When the InterruptMutex is unlocked again, the previous interrupt state is restored. +This does not completely rule out deadlocks, since you can just enable interrupts manually when you should not. +Still, it is very convenient to just change the mutex type of data that is shared with interrupt handlers instead of disabling and enabling interrupts manually on every access.

            +
            // Make a mutex of your choice into an `InterruptMutex`.
+type InterruptSpinlock<T> = interrupt_mutex::InterruptMutex<spinning_top::RawSpinlock, T>;
+
+static X: InterruptSpinlock<Vec<i32>> = InterruptSpinlock::new(Vec::new());
+
+fn interrupt_handler() {
+    X.lock().push(1);
+}
+
+let v = X.lock();
+// Raise an interrupt
+raise_interrupt();
+assert_eq!(*v, vec![]);
+drop(v);
+
+// The interrupt handler runs
+
+let v = X.lock();
+assert_eq!(*v, vec![1]);
+drop(v);
+
            +

            mkroening/interrupt-ref-cell

            +

            (Section written by @mkroening)

            +

            Also building upon last month's interrupts crate, I created a RefCell for sharing data with interrupt handlers or signal handlers on the same thread.

            +

            On the same thread (software thread or hardware thread (core)), a compiler fence is sufficient for synchronization with signal handlers (on Unix) and interrupt handlers (on bare metal). +In these cases, the new InterruptRefCell allows easy sharing without the overhead of mutexes and without the deadlock potential of mutexes. +Similar to InterruptMutex, this is helpful for disabling interrupts on accesses but does not protect you from manually enabling interrupts while holding a reference.

            +
            use interrupt_ref_cell::{InterruptRefCell, LocalKeyExt};
+ 
+thread_local! {
+    static X: InterruptRefCell<Vec<i32>> = InterruptRefCell::new(Vec::new());
+}
+ 
+fn interrupt_handler() {
+    X.with_borrow_mut(|v| v.push(1));
+}
+
+X.with_borrow(|v| {
+    // Raise an interrupt
+    raise_interrupt();
+    assert_eq!(*v, vec![]);
+});
+ 
+// The interrupt handler runs
+ 
+X.with_borrow(|v| assert_eq!(*v, vec![1]));
+
            + +

                  rust-osdev Projects

                  +

                  In this section, we give an overview of notable changes to the projects hosted under the rust-osdev organization.

                  + +

                  x86_64

                  +

                  Maintained by @phil-opp, @josephlr, and @Freax13

                  +

                  The x86_64 crate provides various abstractions for x86_64 systems, including wrappers for CPU instructions, access to processor-specific registers, and abstraction types for architecture-specific structures such as page tables and descriptor tables.

                  +

                  We merged the following PR this month:

                  + +

                  We also merged the following changes into the next branch, which will be released as v0.15 soon:

                  + +

                  bootloader

                  +

                  Maintained by @phil-opp

                  +

                  The bootloader crate implements a custom Rust-based bootloader for easy loading of 64-bit ELF executables. This month, we merged the following nightly fixes:

                  + +

                  acpi

                  +

                  Maintained by @IsaacWoods

                  +

                  The acpi repository contains crates for parsing the ACPI tables – data structures that the firmware of modern computers use to relay information about the hardware to the OS. We merged the following changes this month:

                  + +

                  Thanks to @Spartan2909 for their contribution!

                  +

                  uefi-rs

                  +

                  Maintained by @GabrielMajeri, @nicholasbishop, and @phip1611

                  +

                  The uefi-rs crate provides safe and performant wrappers for UEFI, the successor to the BIOS. We merged the following PRs this month:

                  + + + + +

                  Thanks to @gurry for their contribution!

                  phip1611/phipsboot

                  +

                  (Section written by @phip1611)

                  +

                  I'd like to announce my project PhipsBoot. 🎉 PhipsBoot is a relocatable x86_64 +bootloader for legacy x86_64 boot written in Rust and assembly. It is intended +to be loaded by GRUB via Multiboot2, where it uncovers its main benefit: It is +relocatable in physical memory without having relocation information in the +ELF! It outsources a lot of complexity to GRUB which also better fits into +the ecosystem and makes it easier usable. The README contains more background +about why I have chosen to use GRUB instead of writing my own stage 1 +bootloader.

                  +

                  This project combines a lot of toolchain and binary knowledge and experience I +collected and gained in recent years about legacy x86_64 boot. The main +contribution IMHO is how the binary is assembled and that the thing boots +with all the properties described in the README, but not the high-level +functionality itself.

                  +

                  I am especially proud of the well-commented structure of the assembly files. +For example the whole page-table mappings are done IMHO very nicely even tho +it is assembly language. Also, I think it turned out quite cool how I configured +the linker script. I hope this can be a learning resource for others!

                  +

                  TL;DR: It is a learning ground and a reference for how to solve the relocation +problem with Multiboot2 and GRUB, as GRUB is not able to load DYN ELFs.

                  +

                  You have multiple options for testing it out:

                  +
                    +
                  • $ cloud-hypervisor --debug-console file=log.txt --kernel ./build/phipsboot.elf64 (using Xen PVH)
                    • +
                  • $ qemu-system-x86_64 -kernel ./build/phipsboot.elf32 -debugcon stdio (using Multiboot 1)
                    • +

                    rust-osdev Projects

                    +

                    In this section, we give an overview of notable changes to the projects hosted under the rust-osdev organization.

                    x86_64

                    +

                    Maintained by @phil-opp, @josephlr, and @Freax13

                    +

                    The x86_64 crate provides various abstractions for x86_64 systems, including wrappers for CPU instructions, access to processor-specific registers, and abstraction types for architecture-specific structures such as page tables and descriptor tables.

                    +

                    We merged the following PRs this month:

                    uefi-rs

                    +

                    Maintained by @GabrielMajeri, @nicholasbishop, and @phip1611

                    +

                    The uefi-rs crate provides safe and performant wrappers for UEFI, the successor to the BIOS. We merged the following PRs this month:

                    + + +

                    Thanks to @bjorn3 for their contribution!

                    +

                    Maintained by @phil-opp and @Freax13

                    +

                    The bootloader crate implements a custom Rust-based bootloader for easy loading of 64-bit ELF executables. This month, we merged the following improvements:

                    + +

                    Thanks to @vinc and @tsatke for their contributions!

                    Other Projects

                    +

                    In this section, we describe updates to Rust OS projects that are not directly related to the rust-osdev organization. Feel free to create a pull request with the updates of your OS project for the next post.

                  For the next weeks/months, my plan is to finish the UEFI bootloader implementation and then adjust the blog to work with both the BIOS and UEFI bootloaders. Among other things, this will require that we switch from the VGA text buffer to a pixel-based framebuffer because the VGA text mode is not available with UEFI. While this makes things more complicated (we need to do some simple font rendering and add slice support to volatile crate), it will allow us to create our own graphical user interface, render a mouse pointer, or display images.

                  In in our previous status update I described my plans to rewrite the blog on top of the upcoming UEFI bootloader. In the past month I started rewriting the Minimal Rust Kernel post for this. Unfortunately, I'm still facing build-related issues because of limitations of Cargo's config files. To resolve these (and other) .cargo/config issues, I created a proposal on the Rust internals forum to make some .cargo/config options available in Cargo.toml too. Feel free to join the discussion if it's relevant to you!

                  Third Edition

                  Photo of the laptop display, showing some text output

                  This is an old Acer TravelMate laptop of mine, booting from a USB stick. The output shows that it successfully sets up the local and IO-APIC for interrupt handling and then listens for timer and keyboard interrupts, just as before. The screen output is now based on a pixel-based framebuffer, using the font8x8 crate for simple font rendering. The memory management code required almost no changes, since the interface provided by the bootloader stayed almost the same (there are only some differences in the memory map format).

                I probably won't get all of that done in March, but those are my planned next steps. Thanks to this great community and to @phil-opp for being so helpful in the osdev journey!
