Hey Mentor,
Below is my detailed project proposal for enhancing NetBSD’s Linux compatibility layer. I’m super excited to dive in and make this system next-level! I’ve mapped out every step (350 hours total) with continuous check-ins and iterative feedback so that we can pivot or refine as needed—all while keeping things frictionless and straight to the point.

The mission is to boost NetBSD’s Linux compatibility layer (aka
compat_linux) by identifying and implementing the missing Linux syscalls. In short, I want unmodified Linux binaries to run seamlessly on NetBSD, expanding its utility and appeal.Deliverables:
- Code:
- New syscall implementations (both direct mappings and full emulations) integrated as a patch set.
- Documentation:
- Detailed design documents, implementation blueprints, and comprehensive test cases.
- User/developer guides (with interactive elements like wiki pages or video walkthroughs).
- Testing:
- Automated and manual test suites to ensure reliability and performance.
- Community Integration:
- Clean commit messages, change logs, and follow-up reports on community feedback.
Additional Details
Is Similar Software Available Elsewhere?
Yes, FreeBSD’s linuxulator and OpenBSD’s limited Linux compatibility exist—but this implementation is tailored for NetBSD’s unique architecture and strict licensing (no GPL in the kernel), making it an original, high-quality solution.

Port or Rewrite?
This isn’t a port. It’s a rewrite/extension of the current compatibility layer, built entirely from scratch to meet NetBSD’s standards and licensing.

About My Experience with NetBSD
- 1) Modify an Existing Syscall – Change a syscall like
getpid()to print debug info.
2) Write a Simple Custom Syscall – Createsys_myhello()that prints "Hello from the kernel!".
Additional Required Knowledge:
I’m very comfortable with Linux syscalls, kernel debugging (gdb, ktrace, strace, kdump), and general system programming principles. My background ensures I can bridge the gap between Linux and NetBSD effectively.
Hardware:
This is a pure software project, so no specialized hardware is needed.

About Me
- Background:
I’ve been programming in C for over 3 years, focusing on system-level projects—from low-level system tools to performance optimizations. I’ve typically worked solo or in small agile teams. - Prior Projects:
- Log Monitor Utility:
A real-time log parser that watches system logs and flags events can be implemented efficiently, especially if it's focused on core functionality. - NetBSD Experience:
I’m actively diving into NetBSD’s internals and have been engaging with the community on mailing lists. Although I haven’t yet submitted patches, I’m well on my way. - Contact:adithyareddy666666%gmail.com@localhost
