Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

Unreleased

Added

  • Incorporated plugin_name and plugin_version into the Plugin struct
  • Drop::drop is called on plugins when sudo exits
  • Support for the change_winsize callback. Requires sudo 1.8.21 or greater.

Changed

  • Wrapped printf_facility plugin argument into a dedicated PrintFacility struct to wrap all user communication.
  • Moved much of the work done in the sudo_io_plugin! macro to non-macro code.
  • Almost complete rewrite of the internals to be more Rust-like, and use traits to reduce the amount of macro magic necessary.
  • Autodetect what version of the sudo_plugin API is supported by the version of sudo_plugin-sys we're linked against.
  • Now uses a prelude-style import.
  • Replaced error-chain with thiserror.
  • Completely reworked error handling. Plugin implementations may now provide coercions from sudo_plugin internal errors to appropriate return codes. The provided Error type defaults to aborting the session on error.
  • Plugins no longer mutable when calling log_* functions.

Fixed

  • Panics inside of plugins no longer cause undefined behavior by crossing FFI boundaries. All panics are caught at the boundaries and turned into an appropriate error type.

  • No longer segfaults against sudo >= 1.9 which introduced API changes that require the ability to write into the plugin.

1.2.0 - 2020-03-26

Added

  • Automatic support for -V flag, which prints the version of sudo and any active plugins

Changed

  • Builds using Rust 2018
  • No longer fails to build on warnings, unless being run in CI
  • Allows plugins to use any error library they wish, as long as the error types returned in Results implement Into<sudo_plugin::errors::Error>.

1.1.0 - 2018-05-18

Added

  • Support writing directly to the user's TTY

Changed

  • UserInfo::tty is now a PathBuf instead of a String.
  • Depends on sudo_plugin-sys ~1.1, which changed mutability of pointer arguments due to bindgen 0.37

1.0.0 - 2018-05-07

Added

  • Macros to simplify writing sudo plugins
  • Full compatibility with plugin API versions up to 1.12
