Hi, when I try to load a sparse file via ext4load, I am getting the error message 'invalid extent' After a deeper look in the code, it seems to be an issue in the function ext4fs_get_extent_block in fs/ext4/ext4_common.c: The file starts with 1k of zeros. The blocksize is 1024. So the first extend block contains the following information: eh_entries: 1 eh_depth: 1 ei_block 1 When the upper layer (ext4fs_read_file) asks for fileblock 0, we are running in the 'invalid extent' error message. For me it seems, that the code is not prepared for handling a sparse block at the beginning of the file. The following change, solved my problem: I am really not an expert in ext4 filesystems. Can somebody please have a look at this issue and give me a feedback, if I am totally wrong or not? |
