    Phoronix: Encryption Support For EXT4

    Ted Ts'o at Google has implemented EXT4 encryption support that will likely be baked into the next Android "M" release and is being worked toward for mainline inclusion in the upstream Linux kernel...

    The google docs link in the mail asks me for a google login. Perhaps I'll learn later then how this works.

      Flip through the mailing list, he accidentally posted the wrong link. On Mobile so I can't give you exact link, but he does post the correct link after someone points it out.
      All opinions are my own not those of my employer if you know who they are.

        Would be more useful if it was developed for BTRFS...

          complete with file-name and symlink encryption
          Doesnt sound like partition would not be fully encrypted, but more like parts of metadata + data. Given that makes me wonder why would anyone want to use it when there is LUKS with everything encrypted. Google can keep it..

            I'm tired having to use hundreds of layers on top of layers: native encryption is welcome

              Perhaps there are scenarios where you just want to encrypt a couple of directories? And not deal with the hassles of FDE? And keep a system bootable and working with basic functionality even if the user forgets the password? Like.. dunno.. a phone?

                IIRC Btrfs already has encryption support.

                  Btrfs does support encryption but native one.

                  You shouldn't say IIRC about the info that can be easily reached IMO

                    It could work like openwrt. Read only root for restore and read-write user partition.
