Hi All Yesterday I checked in xattrib support. This is available through both Linux and Yaffs Direct. The xattribs are stored in unused space in the object header which limits the amount of xattrib info that can be stored to approximately (page_size - 512). Thus with 2k page NAND you'll get approx 1500 bytes of xattrib. From my limited understanding of how xattribs are used, this should be enough for most applications (SELinux uses around 200 bytes). To enable xattrib support in Linux you will need to set CONFIG_YAFFS_XATTRIB. For Yaffs Direct you will need to set param.enableXattrib=1; Any feedback welcome. -- Charles
