The EP_CTX_BLOB seems to have both WRITE and EXECUTABLE permissions enabled

[vthaniel]

Describe the issue

The EP_CTX_BLOB (The compiled model saved as an ONNX blob on the disk) seems to have WRITE and EXECUTABLE permissions enabled. Since a compiled blob is meant to be read from, I think only READ permissions are sufficient.

To reproduce

Use the following Session Configuration to save the EP context blob on the disk

sessionOptions.AddConfigEntry(kOrtSessionOptionEpContextEnable, "1");

Then check the permissions enabled on the saved file

On Windows does it matter?

[vthaniel]

Hello IMHO it would be better not to have executable permissions (unless there is a reason) In Linux the same file does not seem to have executable permission. It comes as follows rw-rw-r--

[snnn]

On Linux it is controlled by umask. It depends on how the user setting was set. I think it should not be part of ONNX Runtime's logic. We should just rely on the operating system's default. Windows's permission model is quite different. I think executable permission bit is not very useful.
