Integer division by 0 in `tf.raw_ops.AllToAll`
Impact
The shape inference code for AllToAll can be made to execute a division by 0:
import tensorflow as tf
@tf.function
def func():
return tf.raw_ops.AllToAll(
input=[0.0, 0.1652, 0.6543],
group_assignment=[1, -1],
concat_dimension=0,
split_dimension=0,
split_count=0)
func()This occurs whenever the split_count argument is 0:
TF_RETURN_IF_ERROR(c->GetAttr("split_count", &split_count));
...
for (int32_t i = 0; i < rank; ++i) {
...
dims[i] = c->MakeDim(c->Value(dims[i]) / split_count);
...
}Patches
We have patched the issue in GitHub commit a8ad3e5e79c75f36edb81e0ba3f3c0c5442aeddc.
The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range.
