Bugs with jffs2reader

[ygator at yahoo.com]

Hello, 

I sent this once and have my subscription set to receive my own posts, but I never saw it show up on the list.
I've now turned on Receive acknowledgement and will try again.

I wanted to report that I have run across 3 bugs with jffs2reader. 
The image used in the these findings is located here: http://toko.baliwae.com/download/1.8.5.1B_201513211614.zip 
Below is the partial output of jffs2reader and jffs2dump on the image. 

1. Incorrect file size shown on output (see jffs2reader output below).  Any file with a size of 4096 or above is reported as 4096. 
2. Extracting a file using -f option yields only the first max 4096 characters of the file. 
3. jffs2reader not seeing first entry in image.  So looking at jffs2dump shows 3518 directory as the first entry, but jffs2reader does not see. 

I found that the first two bugs were fixed in the code located https://github.com/vamanea/mtd-utils 

Thanks
