STATUS_EAS_NOT_SUPPORTED is received from NTFS when attempting to read the file EA

Hi,

My FS filter use NTFS file Extended Attributes to store per file metadata.

EA is read during IRP_MJ_CREATE processing just before completing the
request.

EA is read successfully most of the time, but sometimes I receive
STATUS_EAS_NOT_SUPPORTED attempting to read the file EA.

I would appreciate if any help with this problem.

I believe you can get this if there’s already a reparse point on the
file. Is it an NTFS symlink by any chance?

No, it is a regular file. And its EA was successfully read previously.
