Problems mounting home with encfs 1.9.1

[gcala]

Hi, sorry for cross-posting an issue but on archlinux forum [1] I received no help.

The problem summoned updating a laptop with home encrypted through encfs. I used it a few months ago, when encfs was at version 1.8.1. I also installed pam_encfs [2] and kwallet-pam [3] to decrypt/login with the same password. All was fine. The previous week I booted the laptop, it worked as usual; I full-upgraded the system, including encfs-1.9.1. After a reboot and login as usual, kde is unable to load: it shows errors regarding missing configuration files. Seems that initially the home is decrypted/mounted but right after it is unmounted preventing kde to complete boot process. Login from terminal works as expected. The only solution I found was to downgrade to encfs-1.8.1.

This is my setup:

/etc/pam.d/system-login

#%PAM-1.0

auth       required   pam_tally.so         onerr=succeed file=/var/log/faillog
auth       required   pam_shells.so
auth       requisite  pam_nologin.so
auth	   sufficient pam_encfs.so
auth       include    system-auth

account    required   pam_access.so
account    required   pam_nologin.so
account    include    system-auth

password   include    system-auth

session    required     pam_encfs.so

/etc/pam.d/sddm

Any idea about the problem? Very thanks.

See #263 ?

sorry for my delayed answear. I read #263 and tryed changing /etc/security/pam_encfs.conf with the following lines:

encfs_default --no-default-flags
fuse_default use_ino,nonempty

Initially, it looked as it was the right solution, until I start chrome: it starts for a couple of seconds then quits and with it all my kde session. Seems that only chrome triggers this issue; i tryed chromium, vivaldi, steam, kdevelop, etc without any hassle.

Unfortunately, some time happens that the problem pops just after the login, without triggering chrome.

I returned to encfs 1.8.1 for stability.

Thanks

Could also be related to #214 / #244.

[benrubson]

@gcala #214 / #244 should now be solved, would you give master branch a test and close this issue if solved ?
Thank you 👍

[gcala]

sorry for my delayed answear, unfortunately last commits didn't solve my issues

[benrubson]

Certainly you are facing the same bug as in #214.
Let's then try first to solve #214, we will then see if it solves your issue 👍

Ok looks like #214, let's continue there.
