Project detail pages (templates/project.html): - Add a mono "user@machine:~$ man " prompt line under the title. Styling (static/style.css): - Add .gsoc-ideas/.gsoc-card/.gsoc-meta/.gsoc-badge (+ diff-easy/medium/hard) and .page-prompt rules, reusing existing color tokens.

+ +

Skills: Rust, Unicode/locale handling.

+
+ +
+

Code refactoring for procps, util-linux & bsdutils

+
+ Medium + ~175h + Mentor: Sylvestre +

  • Eliminate duplicated code across the three projects
    • +
  • Unify the documentation and test scaffolding
    • +
  • Improve maintainability and shared infrastructure

A multicall binary and core library for findutils

+
+ Medium + ~175h + Mentor: TBD +
+

findutils currently consists of a few unconnected binaries. Build a multicall binary (like coreutils) and a library of shared functions (like uucore).

+
    +
  • Design a unified multicall entry point
    • +
  • Extract shared functionality into a core library

+
    +
  • Adapt the coreutils CI approach to each project
    • +
  • Wire the test suites into GitHub Actions
    • +
  • Track and report compatibility over time

Symbolic/fuzz testing and formal verification of tool grammars

+
+ Mixed + Size: Mixed + Mentor: TBD (informally @chadbrewbaker) +
+

Inspired by lightweight formal methods at AWS; most KLEE scaffolding was done for KLEE 2021. Start with wc, formalize its command-line grammar, run it under AFL++ and KLEE, then generalize.

+
    +
  • Add proofs of resource use and correctness, especially around syscalls and memory
    • +
  • Unify fuzzer and KLEE seeds so they help each other find paths
    • +
  • Formalize the wc UTF-8 inner loop into a SIMD-friendly automaton / monoid
    • +
  • Automate detection of accidentally quadratic behavior
    • +
+

Skills: Rust, KLEE, AFL++, SMT solvers (Z3, CVC5), TLA+/Alloy, grammar testing.

+
+ +
+

Official Redox support

+
+ Medium + ~175h + Mentor: TBD +
+

We want to support the Redox operating system but are not actively testing against it. Since the last round of fixes in #2550, regressions have likely crept in.

+
    +
  • Set up Redox in CI
    • +
  • Fix the issues that arise and port missing features
    • +
+

Skills: Rust, cross-platform/OS development.
