Add ISO-003 cross-cage vmmap escape tests by lionne99 · Pull Request #1333 · Lind-Project/lind-wasm

lionne99 · 2026-07-27T20:34:15Z

Adds ISO-003 tests to verify that invalid memory ranges cannot escape the cage memory boundaries.

Changes
Added cross_cage_vmmap_escape.c unit test:

Verifies that writing from a fully unmapped region returns EFAULT
Verifies that writing across a mapped/unmapped page boundary is rejected
Verifies that extremely large lengths that could overflow range calculations are rejected
Uses a pipe canary check to ensure failed writes do not partially modify the destination

Added vmmap unit tests:

Added coverage for rejecting address range calculations with overflowing lengths
Added coverage for calculate_page_range returning None when the requested range overflows

Thanks for the PR! The tests are well-designed overall. Few things:

Worth also testing read(fd, bad_buf, len) = host (writing into cage memory).
Worth documenting in a comment: Test 2/3 assume native Linux returns a full EFAULT (rather than a POSIX-permitted partial write) for a straddling buffer on a pipe. Not all kernel has same behavior on this case

+        let mut vmmap = Vmmap::new();
+        vmmap.set_base_address(0);


Can we use test_vmmap() here?
