Test Case: chown Rejection

Test ID: TC062-setattr-chown-reject Category: Read-Only Enforcement Priority: Critical

Objective

Verify a privileged direct chown request returns EROFS and leaves ownership unchanged.

Procedure

Mount vfs/vfs-plain.erofs as root and run:

./g3_vfs_probe stat /tmp/repo22-g3/mnt/testdir/file.txt > TC062-before.txt
./g3_vfs_probe expect-error chown \
  /tmp/repo22-g3/mnt/testdir/file.txt 30
./g3_vfs_probe stat /tmp/repo22-g3/mnt/testdir/file.txt > TC062-after.txt
cmp TC062-before.txt TC062-after.txt

Expected Results

chown to uid/gid 65534 reports errno 30 and metadata remains unchanged. Record output and cleanup.
