[Bug 507150] Re: Encrypted home directory doesn't always dismount after logout.
*** This bug is a duplicate of bug 313812 *** https://bugs.launchpad.net/bugs/313812 Also - most of the above processes only exist for graphical logins. However, the private folder isn't unmounted for non-graphical logins either even though there are no processes left behind and the counter in /dev/shm/ecrypt-$USER-Private no longer exists. Sorry I didn't mention this before but this problem has existed for quite a while and still exists in Ubuntu 17.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/507150 Title: Encrypted home directory doesn't always dismount after logout.

*** This bug is a duplicate of bug 313812 *** https://bugs.launchpad.net/bugs/313812 This isn't really a duplicate of bug #313812. The home directory is not being unmounted. Bug #313812 concerns the key-ring. I created a user (zip) with an encrypted home folder, logged in, started a terminal and verified that the encrypted home folder was mounted. I then logged out and logged in as another user with root (sudo) privileges and checked what was mounted. "/home/.ecryptfs/zip/.Private" was still mounted in "/home/zip". I then checked "/dev/shm/ecryptfs-zip- Private" and the value was 1. I then checked what processes owned by "zip" were running. root@braun-asus:~# ps -u zip PID TTY TIME CMD 4173 ?00:00:00 systemd 4183 ?00:00:00 (sd-pam) 4199 ?00:00:00 dbus-daemon 4329 ?00:00:00 gvfsd 4336 ?00:00:00 gvfsd-fuse 4369 ?00:00:00 ibus-daemon 4416 ?00:00:00 ibus-dconf 4465 ?00:00:00 dconf-service 4468 ?00:00:00 ibus-engine-sim 4618 ?00:00:00 evolution-sourc 4633 ?00:00:00 libertined 4672 ?00:00:00 goa-daemon 4708 ?00:00:00 goa-identity-se 4757 ?00:00:01 mission-control 4810 ?00:00:00 gvfs-udisks2-vo 4825 ?00:00:00 gvfs-mtp-volume 4829 ?00:00:00 gvfs-goa-volume 4839 ?00:00:00 gvfs-gphoto2-vo 4848 ?00:00:00 gvfs-afc-volume 4904 ?00:00:00 gconfd-2 4911 ?00:00:00 gvfsd-trash 4937 ?00:00:00 gvfsd-burn 4955 ?00:00:00 gvfsd-metadata 4992 ?00:00:00 zeitgeist-daemo 5000 ?00:00:00 zeitgeist-fts I also checked what files were open by processes owned by "zip" - 164! So it is reasonable that, under these conditions, the encrypted home remained mounted. The problem is that all these process are persisting after log out. I suspect getting rid of them will solve the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/507150 Title: Encrypted home directory doesn't always dismount after logout.

*** This bug is a duplicate of bug 313812 *** https://bugs.launchpad.net/bugs/313812 The portion of this bug dealing with keys is actually a duplicate of Bug #313812, which was recently fixed! As for the rest of it (not unmounting as long as a user is still in the encrypted directory, open file handles, etc), that behavior is by design, and not much we can do to avoid it. Thanks. ** This bug has been marked a duplicate of bug 313812 umount of ecryptfs does not automatically clear the keyring (can be mounted by root later) * You can subscribe to bug 313812 by following this link: https://bugs.launchpad.net/ubuntu/+source/ecryptfs-utils/+bug/313812/+subscribe -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/507150 Title: Encrypted home directory doesn't always dismount after logout. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 507150] Re: Encrypted home directory doesn't always dismount after logout.
I could partially reproduce it. As long as there was a user inside /home/USER (root in my case), the user logged out but his homefolder was not completely umounted. Running mount didn't show it. Running ls, cd, etc would show all the files. Further tests: USER LOG IN ROOT CD /HOME/USER USER LOG OUT # ls [see user's files!] # df . Filesystem 1K-blocks Used Available Use% Mounted on - 8254272 5523548 2311428 71% / # cat /dev/shm/ecryptfs-USER-Private 0 # sudo -u USER keyctl list @u 2 keys in keyring: ... ... # cd / # ls /home/USER [nothing] # sudo -u USER keyctl list @u keyring is empty But the second time I tried the same tests, it was worse: USER LOG IN ROOT CD /HOME/USER USER LOG OUT #ls [see user's files!] # cd / # ls /home/USER [nothing] # sudo -u USER keyctl list @u 2 keys in keyring: ... ... # ps gaux | grep USER USER 3788 0.0 0.0 6460 724 pts/2S13:17 0:00 login # kill -9 3788 # sudo -u USER keyctl list @u keyring is empty So I tried the same thing again, but more nasty. I could see USER's files!!! USER LOG IN ROOT CD /HOME/USER USER LOG OUT # cd / # ls /home/USER [nothing] # sudo -u USER keyctl list @u 2 keys in keyring: ... ... # ps gaux | grep USER USER 3788 0.0 0.0 6460 724 pts/2S13:17 0:00 login # sudo -u anaclara ecryptfs-mount-private # kill -9 3788 # sudo -u USER keyctl list @u keyring is empty # ls /home/USER [See user files!!!] # mount ... /home/USER/.Private on /home/USER type ecryptfs (...) # df /home/USER Filesystem 1K-blocks Used Available Use% Mounted on /home/USER/.Private 90606688 81207632 9399056 90% /home/USER Now when I had another user rather than root that had CDed into USER's home, it was a bit different... When USER logged out it had the message $ exit logout Sessions still open, not unmounting $$ ps gaux | grep USER USER 4497 0.0 0.0 6460 720 pts/2S13:32 0:00 login $$ ls ~USER [See files!] $$ mount [See mounted!] $$ sudo -u USER keyctl list @u Sudo password: * 2 keys in keyring: ... ... $$ sudo umount /home/USER $$ sudo -u USER keyctl list @u keyring is empty $$ So, I could reproduce all sorts of behavior, and it is apparently not deterministic. ** Tags added: apport-collected -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/507150 Title: Encrypted home directory doesn't always dismount after logout. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
