Test Case: VFS Vget Normal Operation

Test ID: TC012-vget-normal

Objective

Exercise VFS_VGET through a real FreeBSD file handle and verify the returned vnode identifies and reads the same EROFS inode as pathname lookup.

Fixture

Use images/compact.erofs, source/compact/testfile.txt, and tests/nfs_fh_tool.c. Compile the helper as described in tests/G1-MANUAL-SETUP.md; run as root.

Procedure

After mounting on $mnt:

stat -f 'path_ino=%i gen=%v size=%z' "$mnt/testfile.txt"
./nfs_fh_tool capture "$mnt/testfile.txt" /tmp/tc012-a.fh
./nfs_fh_tool capture "$mnt/testfile.txt" /tmp/tc012-b.fh
./nfs_fh_tool compare /tmp/tc012-a.fh /tmp/tc012-b.fh
./nfs_fh_tool describe /tmp/tc012-a.fh
./nfs_fh_tool stat /tmp/tc012-a.fh
./nfs_fh_tool cat /tmp/tc012-a.fh /tmp/tc012-fh.out
cmp /tmp/repo22-g1/source/compact/testfile.txt /tmp/tc012-fh.out
sha256 /tmp/repo22-g1/source/compact/testfile.txt /tmp/tc012-fh.out

Remove the handles/output, then unmount and detach.

Expected Results

• Both captures produce the same handle.
• Handle NID, fhstat inode, and pathname inode agree.
• fhopen output matches the deterministic source exactly.
• No stale/duplicate vnode error or cleanup failure occurs.
