# Test Case: chmod Rejection
|
|
|
|
**Test ID**: TC061-setattr-chmod-reject
|
|
**Category**: Read-Only Enforcement
|
|
**Priority**: Critical
|
|
|
|
## Objective
|
|
|
|
Verify a direct chmod request returns EROFS and leaves metadata unchanged.
|
|
|
|
## Procedure
|
|
|
|
Mount vfs/vfs-plain.erofs and run:
|
|
|
|
./g3_vfs_probe stat /tmp/repo22-g3/mnt/testdir/file.txt > TC061-before.txt
|
|
./g3_vfs_probe expect-error chmod \
|
|
/tmp/repo22-g3/mnt/testdir/file.txt 30
|
|
./g3_vfs_probe stat /tmp/repo22-g3/mnt/testdir/file.txt > TC061-after.txt
|
|
cmp TC061-before.txt TC061-after.txt
|
|
|
|
## Expected Results
|
|
|
|
chmod reports errno 30 and complete metadata remains unchanged. Record output,
|
|
fixture hash, and cleanup.
