- AppArmor support
Completed Milestones in the Initial Development Phase
Milestone 0: Preparation
- System architecture and requirements
- Project setup
- Sudoers file parsing
Milestone 1: Drop-in replacement with a default config
- Core sudo pipeline from policy verification to minimal command execution without security features
- Sudoers based policy, with limited feature support
- Authentication based on PAM
- Command execution using exec with basic signal and fd passing
- Test for Ubuntu 22.04 with a default sudoers config
- Setup testing framework
Milestone 2: Security parity
- Core sudo pipeline with full sanitation of signals, file descriptors, limits, ptrace, pty management, etc. and more efficient command execution
- Add su implementation
- Testing for full security compliance
- Wider configuration feature flag support
- User facing documentation
- Credential caching
Milestone 3: Deployability
- Improve usability by implementing commonly used feature flags and configuration options (such as sudo -l, and various reasonable configuration options)
- Implement visudo
- More complete user facing documentation
- First public release of sudo and su aimed at single-user systems
- Support for other Linux distributions than Debian/Ubuntu (i.e. Fedora-based ones)
