umask syscall implementation by moogchi · Pull Request #1239 · Lind-Project/lind-wasm

moogchi · 2026-06-06T22:40:07Z

Description:

Problem:

umask syscall was just a stub that returned -1, which caused the coreutils test failure
The failed tests were:

chmod/equal-x, chmod/equals, chmod/usage — symbolic chmod modes without a who part (e.g. =x) consult the umask to determine which permission bits to set; with umask broken these resolved incorrectly
mkdir/parents, mkdir/perm, mkdir/special-1 — directory permissions came out wrong because the mask was never applied

What changed:

Added a per-cage umask field (AtomicU32, default 0o022) to the Cage struct
Implemented umask_syscall in fs_calls.rs — atomically swaps the new mask in and returns the old one
Applied the umask at file/directory creation time in open_syscall, openat_syscall, mkdir_syscall, and mknod_syscall via mode & !umask
fork correctly inherits the parent's umask (POSIX-compliant)
Updated the glibc umask.c stub to call into the Rust syscall via MAKE_LEGACY_SYSCALL
Added a deterministic test covering return value, open, mkdir, and umask changes

Fixes
