...Each module works in the file system to protect and hide secret files.The motivation: An attacker can read every file in your machine in a bad situation. But if you have a Casper-fs custom module, the attacker will not find the hidden kernel module that has functions to turn any file invisible and protect to block read/remove/edit actions. My beginning purpose at this project is to protect my server, which is to protect my friends' machines. When I talk to friends, I say peoples that don't know how to write low-level code. Using the Casper-fs, you can generate your custom kernel module to protect your secret files. The low-level programmer can write new templates for modules etc.

SLFS is a implementation of log-structured file system designed for flash memory based storages(SSD, SD card, eMMC, …). Like other log-structured file systems, SLFS shows good performance under random write. <Build> 1. deploy SLFS source code at your Kernel Source # tar xzf slfs.tar.gz # mv slfs KERNEL_SRC/fs/. # vi KERNEL_SRC/fs/Makefile (add following line) obj-$(CONFIG_SLFS_FS) += slfs/ # vi KERNEL_SRC/fs/Kconfig (find section “MISC_FILESYSTEMS” and add following...

...(for the 1st datablock) is choosen to represent a 0 or an odd blocknr. to represent an 1. For the remaining blocks of the cover file till the end of the code is reached, an adjacent blocknr. represents the same bit as the previous one and a non-adjacent blocknr. (a block will be skipped) a negated previous bit. It's necessary to use a partition with enough adjacent free blocks (code length + holes for fragmentation) within a blockgroup, for this algorithm to work correctly. ...
