Tock 2.2
Tock 2.2 represents two years of Tock development since v2.1.1. This release contains almost 3900 commits made across 840 PRs by 90 contributors (of which 48 are new contributors!). It is the first Tock release that can compile on a stable Rust toolchain, and contains many other important fixes, new subsystems, new platforms, new drivers, and major refactors.
Backwards Compatibility
Tock 2.2 extends its system call interface through one new system call (Yield-WaitFor), but retains backwards compatibility with Tock 2.1.1 for its core system call interface and all stabilized drivers.
In this release, we revised Tock's alarm system call driver implementation to predictably wrap its ticks values at (2**32 - 1) ticks, across all platforms. Before this change, hardware alarm implementations that were less than 32 bit wide would wrap before reaching (2**32 - 1) ticks, which complicated correct alarm handling in userspace. In Tock 2.2, these alarm implementations are scaled to 32 bit, while also scaling their advertised frequency appropriately. While this change is non-breaking and compatible with the previous alarm implementation, it can expose such scaled alarms to userspace at significantly higher advertised frequency values. Userspace alarm implementations that did not correctly handle such high frequencies may need to be fixed to support this new driver implementation.

Tock 2.2 includes important and security-relevant fixes for its Cortex-M and RISC-V architecture support.
-
When switching between applications, the RISC-V PMP implementation did not correctly invalidate any additional memory protection regions that are not overwritten by the target app's PMP configuration. Under certain conditions this can allow an application to access private memory regions belonging to a different applications (such as when using IPC).
-
The Cortex-M (Armv7-M) and Cortex-M0/M0+ (Armv6-M) hard fault, interrupt and
svchandlers contained a bug that could allow an application to execute inprivilegedmode after returning from the handler. This allows an application to execute code at kernel privileges and read / write arbitrary memory.

This release removes all nightly Rust features from all of Tock's core kernel crates (such as kernel, arch/*, and chips/*). This allows Tock to be built on the Rust stable toolchain for the first time!
We demonstrate this by switching the hail board to a stable toolchain in this release. We continue to compile other boards on the Rust nightly toolchain, as this enables some important code-size optimizations (such as by compiling our own, size-optimized core library).

This Tock release revisits how applications are identified in the kernel, and introduces a set of mechanisms that allow developers to identify, verify, and restrict applications that are running on a Tock kernel. AppIDs are the core mechanism to enable this and identify an application contained in a userspace binary. AppIDs allow the kernel to apply security policies to applications as their code evolves and their binaries change. We specify AppIDs, Credentials and their interactions with process loading in a draft TRD.
Additionally, we introduce a mechanism to assign applications permissions to access some persistent storage (e.g., keys in a key value store). This mechanism interacts with AppIDs (ShortIDs) and is also specified in a a draft TRD.
Relevant PRs:
* Adding App IDs and userspace binary integrity to the Tock kernel by @phil-levis in https://github.com/tock/tock/pull/2809 * AppID/TBF: Add `ShortId` header by @bradjc in https://github.com/tock/tock/pull/4026 * HIL: Add Signature::verify with `const L:usize` and process checker for signatures by @bradjc in https://github.com/tock/tock/pull/3878 * TRD: Tock Storage Permissions by @bradjc in https://github.com/tock/tock/pull/4021 * Add support for ECDSA NIST P256 signature credentials by @alistair23 in https://github.com/tock/tock/pull/4165 * Storage Permissions: Implement to match TRD by @bradjc in https://github.com/tock/tock/pull/4031Major Refactors and Interface Changes
We implement a number of kernel-internal refactors and interface changes:
- System call drivers are now mandated to either return
SuccessorFailure(ErrorCode::NODEVICE)for acommandsystem call with command number0. Previously, some drivers used this command number to also convey additional information to userspace. This release does not change the interface of any stabilized drivers, which will be updated as part of Tock 3.0.
Relevant PRs:
* Syscall Spec: Allow Command 0 to return Success with value or lock it down by @ppannuto in https://github.com/tock/tock/pull/3626 * Update command 0 comments on stabilized userspace drivers by @hudson-ayers in https://github.com/tock/tock/pull/3402 * capsules: ensure driver existence check by @Samir-Rashid in https://github.com/tock/tock/pull/3613- Tock 2.2 introduces [a new policy to support external dependencies][external-deps] in the upstream Tock codebase. As part of this effort, we split up the existing, single
capsulescrate into multipe crates (such ascapsules-core,capsules-extra, andcapsules-system) with different guarantees concerning stability and use of external dependencies. Thecorecapsules crate contains capsules deemed essential to most Tock systems, as well as virtualizers which enable a given single peripheral to be used by multiple clients. Other capsules have been moved to theextracapsules crate. Thesystemcapsules crate contains components that extend the functionality of the Tock core kernel, while not requiringunsafe.
Relevant PRs:
* doc: Add ExternalDependencies.md by @alistair23 in https://github.com/tock/tock/pull/3312 * capsules: split into `core/` and `extra/` (implementing [#3346]) by @lschuermann in https://github.com/tock/tock/pull/3396 * Create system capsules crate, move kernel implementations, update boards by @bradjc in https://github.com/tock/tock/pull/3992- Furthermore, the
DeferredCallandDynamicDeferredCallsubsystems have been replaced with a more lightweight and unified deferred call infrastructure. This new approach has a smaller code size overhead and requires less setup boilerplate code thanDynamicDeferredCall.
Relevant PR:
* Replace DeferredCall and DynamicDeferredCall with a more general-purpose implementation by @hudson-ayers in https://github.com/tock/tock/pull/3382
LeasableBufferhas been renamed toSubSliceand features a significantly improved API. Multiple subsystems have been ported to this new type.
Relevant PRs:
* kernel: LeasableBuffer: fix double slice end value by @bradjc in https://github.com/tock/tock/pull/3511 * kernel: leasablebuffer: add APIs by @bradjc in https://github.com/tock/tock/pull/3505 * Rename `LeasableBuffer` to `SubSlice` by @bradjc in https://github.com/tock/tock/pull/3519 * Switch SPI master HIL to leasable buffers instead of raw slices by @alevy in https://github.com/tock/tock/pull/4173 * ot: tests: switch to subslice by @bradjc in https://github.com/tock/tock/pull/3570 * ot: tests: LB->SS by @bradjc in https://github.com/tock/tock/pull/3573 * Screen: update HIL to simplify, format, and use SubSlice by @bradjc in https://github.com/tock/tock/pull/3792 * kernel: SubSlice: fix slice calculation by @bradjc in https://github.com/tock/tock/pull/3791- Tock 2.2 introduces "configuration boards": variants of in-tree board definition showcasing certain subsystems or peripherals. These boards (under
boards/configurations) are implemented by converting some Tock boards into combined "lib + bin" crates and extending these boards.
Relevant PRs:
* boards: remove nrf52840dk demo by @bradjc in https://github.com/tock/tock/pull/3580 * Add Configuration Boards by @bradjc in https://github.com/tock/tock/pull/3873 * Add nRF52840DK-based Thread tutorial board definition by @lschuermann in https://github.com/tock/tock/pull/3979 * boards/nrf52840dk: split into lib+bin crates for configuration/tutorial boards by @lschuermann in https://github.com/tock/tock/pull/3981 * boards: add tutorial board for HOTP tutorial by @bradjc in https://github.com/tock/tock/pull/4027- Tock can now be built entirely using
cargoand without its Makefiles. This change also simplifies downstream board definitions:
Relevant PR: * Migrate build to be entirely cargo-based, with make as integration tool by @bradjc in https://github.com/tock/tock/pull/4075
- A new
StreamingProcessSlicehelper provides a reusable data structure to convey a "stream" of data from capsures to userspace. This is used in Tock's new CAN driver, and is useful for ADC, networking, etc.
Relevant PR: * Migrate build to be entirely cargo-based, with make as integration tool by @bradjc in https://github.com/tock/tock/pull/4075
- Tock introduces a new interface for custom implementations of the userspace-syscall boundary to hook into the RISC-V trap handler, by specifying which registers are clobbered and providing a generic trampoline to jump to custom code on a trap.
Relevant PR: * arch/rv32i: separate kernel and app trap handlers by @lschuermann in https://github.com/tock/tock/pull/4009

We can now join a Thread network by running OpenThread as a libtock-c userspace implementation, thanks to a major refactor and redesign of Tock's IEEE 802.15.4 and 6LoWPAN stack.
Known issue: UDP transmit functionality is currently broken with a bug / inconsistency between the kernel and libtock-c implementation. When executing the transmit syscall, the libtock-c application fails to provide the src address and fails the error check that occurs for the transmit syscall.
