Needs more investigation, it seems that the new size (new meta-data) is indeed written to disk but for some reason when the object is re-open, the wrong header index is used and the previous header is read (hence the older size is assumed). |

Please add jenswi-linaro@430eaf3 It fixes one error. I'm working on the remaining error. |

When an object is truncated but the number of blocks is unchanged, only the metadata's length field is modified. The hash tree layer has to be notified so that it knows it has to flush the data before closing the object, otherwise the truncation is lost. Add a function for that purpose: tee_fs_htree_meta_set_dirty(), and call it whenever meta->length is updated.

Includes the meta data when calculating the hash of the root node to detect changes in file length while number of blocks is unchanged.
