MentOS Files

MentOS v0.10.0 is the release that brings resumable kernel execution into the scheduler, together with the memory-safety, filesystem, testing and documentation work needed to make that change dependable.

Kernel execution and scheduling

• Added resumable kernel continuations for blocking paths, including scheduler integration, wait queues, timer wakeups and signal delivery.
• Added explicit kernel continuation-stack sizing, guard-page protection and stack-canary checks.
• Preserved FPU state across context switches and added focused continuation, timer, signal and FPU tests.
• Removed obsolete stack-switch symbols and clarified scheduler/process lifecycle documentation.

Memory safety and fault handling

• Added bounded user-memory access helpers and applied validation across syscall boundaries, including execve, read, write, time, pipe and terminal operations.
• Hardened page-directory setup and page-fault diagnostics, including nested-fault reporting and accurate kernel stack ranges.
• Added argument/vector size limits and clearer execve failure reporting.

Filesystem and IPC correctness

• Fixed ext2 allocation, directory iteration, sparse-block, symlink, truncation and metadata error paths.
• Corrected pipe EOF, wakeup and locking behavior, and added coverage for buffered data after the last writer closes.
• Fixed procfs record layout, EOF handling and optional scheduler-feedback exposure.
• Corrected signal sender reporting, nice() handling and synchronization syscall registration.

Tooling, tests and documentation

• Expanded the userspace suite to 87 tests and improved test-runner failure reporting.
• Added kernel unit-test boot mode and stronger CI coverage across GCC, Clang and macOS.
• Centralized repository maintenance guidance in AGENTS.md, expanded maintainer documentation and moved CMake helpers under cmake/.

Verification

All required GitHub checks passed for the release PR, including Ubuntu Build and Test, kernel unit tests, GCC and Clang builds, macOS compilation, Doxygen generation and log-format validation.

The bootloader/kernel separation remains planned follow-up work in [#464]; it is intentionally outside this release.
