Summary0015160: ecryptfs - qemu lxc guest shoots the host in the head
Descriptionhi guys,

I have a lxc guest(centos 7.5) on an ecryptfs mounted folder(using centosplus' kernel C7.5)
Copying data to that folder seems to work just fine, but when I start the quest, the host gets shot in the head almost immediately(maybe 2s after start), hard reboot, no dump.
I encryptfs with passphrase, fstab is:

noauto,rw,relatime,ecryptfs_fnek_sig=be4f540ca10d7dbc,ecryptfs_sig=be4f540ca10d7dbc,ecryptfs_cipher=aes,ecryptfs_key_bytes=32,ecryptfs_passthrough,ecryptfs_unlink_sigs

probably very easy to reproduce.

many thanks, L.

@lejeczek, I can no longer replicate the problem from bug 15353 with the kernel in this link https://people.centos.org/toracat/kernel/7/plus/bug_ecrypt_3/

Please test and report.
Thanks!

hi guys,
I'll apologize as I cannot test/reproduce ecryptfs as I moved away from it, at least for now.
