this is a bug on bigendian machines, Who prepares a patch?
Best regards

In function: ext2fs_read_file(ext2fs_node_t node, int pos, unsigned int len, char *buf)
You may not be getting all the bytes you requested in the 'len' parameter. Your requested length might be improperly adjusted. ----------------------- Code snippet ------------- unsigned int filesize = node->inode.size;
/* Adjust len so it we can't read past the end of the file. */ if (len > filesize) { len = filesize; }
"len" is the native requested size, while "filesize" is the files real size, but byte-swapped and the two are being compared. As long as the byte-swapped length value is larger than the requested size value, then you'll never have a problem.
Now assume the file is 2meg and you requested 2meg.
IF( len=200000 (2meg) > filesize=2000(2meg byte-swapped) ) THEN len = filesize
You end up getting only 2000 bytes.
The initialization of filesize should be: unsigned int filesize = __le32_to_cpu (node->inode.size); Not: unsigned int filesize = node->inode.size;
