Hi!quoted
This patchset proposes a method for encrypting in EXT4 data read and write paths. It's a proof-of-concept/prototype only right now. Outstanding issues: * While it seems to work well with complex tasks like a parallel kernel build, fsx is pretty good at reliably breaking it in its current form. I think it's trying to decrypt a page of all zeros when doing a mmap'd write after an falloc. I want to get feedback on the overall approach before I spend too much time bug-hunting.
Can I keep just a subtree (/home/pavel/.ssh) encrypted?
Ok, as far as I can tell no, this is whole filesystem encryption for now. I guess encrypting based on some attribute is planned...? Best regards, Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
