[Bug 259293] Re: Ecryptfs Private Directory Randomly Unmounts

 

Patch attached.

I've tested this about as much as I can, throwing a number of cases at
it, and it seems to do the right thing for me.  It seems to handle
cronjobs, multiple console logins, and multiple ssh logins properly.

I'd like to get one of our security guys to review this (jdstrand and/or
kees), as well as one of our PAM guys (slangasek and/or pitti).  I'll
also try to get some feedback from the other ecryptfs upstream
maintainers (mhalcrow and/or tyhicks).

Note that the new code does **not** run within the setuid portion of the
code, so it should be low risk from a security perspective.

I'll also put a package in my PPA, any testing would be **much**
appreciated.

Bug description:
Binary package hint: libecryptfs0

On my Asus EEE901, I have set up an encrypted private directory as per instructions on one of the developers blogs. It works perfectly, except that it seems to randomly unmount - it seems to be triggered by shutting the lid, but not always.

This is Ubuntu Intrepid, all updates current, KDE desktop. All there is within my Private folder is .ssh/, .gnupg/, .opera/, and Documents/ all symlinked to the same name in my home folder.

It's possible that this is by design that it unmounts when you leave your laptop, but if so this is redundant as it can be remounted immediately by using the mount.ecryptfs_private command without password prompting.
