# Tock 2.2

Tock 2.2 represents almost two years of Tock development since v2.1.1. This release contains 3882 commits made across 836 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 2.1.1 extends its system call interface through one new system call ([`Yield-WaitFor`](https://github.com/tock/tock/pull/3577)), but retains backwards compatbility with Tock 2.1.1 for its core system call interface and all [stabilized drivers][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.

* capsules/alarm: left-justify 32 bit ticks, re-architect alarm, add unit tests
by @lschuermann in https://github.com/tock/tock/pull/3975

## Security and `arch`-crate Fixes

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).

Relevant PR:
* rv32i/{pmp,epmp}: invalidate unused regions on config switch by @lschuermann
in https://github.com/tock/tock/pull/3541

* The Cortex-M (Armv7-M) and Cortex-M0 (Armv6-M) hard fault, interrupt and `svc`
handlers contained a bug that could allow an application to execute in
`privileged` mode after returning from the handler. This allows an application
to execute code at kernel privileges and read / write arbitrary memory.

</details>

## Stable Rust Support

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).

<details><summary>Relevant PRs:</summary>

* Remove `#![feature(naked_functions)]` and compile Cortex-M on stable! by
@bradjc in https://github.com/tock/tock/pull/3802

## `AppID`, Credentials and Storage Permissions

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][appid-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][storageperms-trd].

## Major Refactors and Interface Changes

We implement a number of kernel-internal refactors and interface changes:

- System call drivers are now mandated to either return `Success` or
`Failure(ErrorCode::NODEVICE)` for a `command` system call with command number
`0`. 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][stabilized-drivers], which will be
updated as part of Tock 3.0.

<details><summary>Relevant PRs:</summary>

* 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

</details>

- 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 `capsules` crate into multipe crates
(such as `capsules-core`, `capsules-extra`, and `capsules-system`) with
different guarantees concerning stability and use of external
dependencies. The `core` capsules 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
the `extra` capsules crate. The `system` capsules crate contains components
that extend the functionality of the Tock core kernel, while not requiring
`unsafe`.

<details><summary>Relevant PRs:</summary>

* doc: Add ExternalDependencies.md by @alistair23 in

* capsules: split into `core/` and `extra/` (implementing #3346) by

- Furthermore, the `DeferredCall` and `DynamicDeferredCall` subsystems 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 than `DynamicDeferredCall`.

Relevant PR:
* Replace `DeferredCall` and `DynamicDeferredCall` with a more general-purpose
implementation by @hudson-ayers in https://github.com/tock/tock/pull/3382

- `LeasableBuffer` has been renamed to `SubSlice` and features a significantly
improved API. Multiple subsystems have been ported to this new type.

- 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.

- Tock can now be built entirely using `cargo` and 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 `StreamingProcessSlice` helper 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:
* Add `StreamingProcessSlice` helper, based on `ProcessSliceBuffer` design
(#4023) by @lschuermann in https://github.com/tock/tock/pull/4208

- 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.
