privilege_utils.hpp

1. Overview

The privilege_utils.hpp file detects elevated execution and relaunches operations that require raw-device access.

This is an interface and data-contract file. It declares the public and internal types used by this subsystem, allowing implementation files and callers to share a stable compile-time contract.

Its paired source or interface file is privilege_utils.cpp.

Primary responsibilities:

  • Check effective privileges
  • Build safe elevated command lines
  • Launch through pkexec or equivalent integration

2. File Identity and Scope

  • Source path: src/privilege_utils.hpp
  • Language: C++
  • File role: interface and data-contract file
  • Physical lines: 13
  • Non-empty lines: 11
  • SHA-256: 77b1fdc971ccf8861665ecb381db6742f9cafd7d76542df4f5992dc70016ba90

The declarations in this file use the global namespace.

3. Dependencies

3.2 Standard and External Headers

  • string

These dependencies define the file’s compile-time integration with the recovery engine, GTK interface, on-disk format decoders, operating-system services, or C++ standard library.

4. Declared Types

  • class PrivilegeUtils.

5. Constants and Configuration Values

No preprocessor or compile-time constants were detected as top-level declarations in this file.

6. Data Members and Persistent State

No class data members are declared directly in this file, or the file primarily implements methods declared elsewhere.

7. API and Function Inventory

The following callable interfaces or definitions were detected:

  • static bool is_running_as_root() – Evaluates the stated condition and returns the corresponding Boolean result.
  • static bool can_read_source(const std::string&path) – Evaluates the stated condition and returns the corresponding Boolean result.
  • static std::string self_executable_path() – Implements the operation identified by this API and updates or returns the associated state.
  • static std::string shell_quote(const std::string&s) – Implements the operation identified by this API and updates or returns the associated state.
  • static std::string build_pkexec_relaunch_command(const std::string&extra_args="") – Constructs the requested object, data structure or user-interface component.
  • static bool launch_pkexec_relaunch(std::string&error,const std::string&extra_args="") – Implements the operation identified by this API and updates or returns the associated state.

8. Operational Flow

The subsystem represented by this file normally participates in the following flow:

  1. Check effective privileges.
  2. Build safe elevated command lines.
  3. Launch through pkexec or equivalent integration.
  4. Expose or execute the detected APIs: is_running_as_root, can_read_source, self_executable_path, shell_quote, build_pkexec_relaunch_command, launch_pkexec_relaunch.
  5. Return explicit results, progress data, recovered records, or diagnostics to the calling layer.

9. Validation and Error Handling

  • Errors are propagated through Boolean results, error strings, logs, exceptions, or status records depending on the API.
  • Input and output paths require existence checks, permission handling and safe destination construction.

10. Runtime, Concurrency, and Resource Management

  • Privileges: some paths involve raw devices, mappings or mounts and therefore require carefully bounded elevated execution.

11. Security and Data-Recovery Considerations

  • Recovery code should prefer read-only source access and avoid writing to the original damaged medium.
  • Raw devices and image files are treated as untrusted binary input; every offset and length must remain bounded by the source size.
  • Operations that open block devices, create mappings or mount filesystems require elevated privileges and should expose the smallest possible privileged surface.

12. Implementation Considerations

  • Changes to public declarations can affect every translation unit that includes this header and should preserve binary and source compatibility where required.

13. Integration with the Recovery Pipeline

  • The file belongs to the source-discovery, parsing or support layer.
  • Its results feed scanner, recovery or reporting modules through shared models.
  • The API should remain deterministic so higher layers can combine results safely.

14. Licensing and Provenance

No explicit copyright or software-license statement was detected in the opening section of this individual file. Distribution terms should therefore be verified against the project-level license and repository metadata.

The SHA-256 value in this document can be used to associate the generated documentation with the exact source version analyzed.
