UBIFS Working On File Encryption Support

Following EXT4 file-system encryption and F2FS per-file encryption support, the UBIFS file-system is also bringing in encryption support built off this fscrypto framework used by EXT4/F2FS.

In making use of fscrypto, the UBIFS file-system encryption support is similar to the EXT4/F2FS implementations and supports not only encrypting the file contents but also the file name. In making use of this framework, it only took around one thousand lines of new code to make it happen from the kernel-side while the user-space changes for supporting UBIFS encryption are still baking. UBIFS for those out of the look is the Unsorted Block Image File-System that's built atop UBI and designed for raw flash memory media.

The work-in-progress patches for UBIFS file encryption support can be found on the kernel mailing list. Hopefully we'll continue seeing more Linux file-systems integrating this native file encryption support.
