[NFS-Ganesha-Devel] Invalid attrs_out->valid_mask in vfs_open2_by_handle

In vfs_open2-> vfs_open2_by_handle for some cases like UNCHECKED create we want to set attrs_out->valid_mask to ATTR_RDATTR_ERR, so that caller should not rely on populated attrs_out and do getattrs to get valid attrs. } else if (attrs_out && attrs_out->request_mask & ATTR_RDATTR_ERR) { attrs_out->valid_mask &= ATTR_RDATTR_ERR; } Doing "&=" is not setting ATTR_RDATTR_ERR as valid_mask is set to 0 by caller. So caller will always rely on attrs_out. We should do "=" here. } else if (attrs_out && attrs_out->request_mask & ATTR_RDATTR_ERR) { attrs_out->valid_mask = ATTR_RDATTR_ERR; } This could happen if there is create with createmode < FSAL_EXCLUSIVE and file is already created with mdcache populated handle. We could end corrupting mdcache attrs in such case. Regards, Gaurav
