Hi!
Kernel 6.7.0-rc8 with BCacheFS new year fixes. Compliled with Debian gcc
13.2.0-9.
BCacheFS tools 1.3.3 – according to bcachefs version – from Debian package
bcachefs-tools 24+really1.3.4-2.
Linux kernel keyutils from Debian package keyutils 1.6.3-2+b2. (Not sure
whether really required.)
Created BCacheFS on external 4 TB SSD:
% mkfs.bcachefs -L […] --data_checksum xxhash --metadata_checksum xxhash
--compression=lz4 --encrypted /dev/sda1
(also tried without xxhash, no difference)
Unlock attempt with incorrect passphrase:
% bcachefs unlock /dev/sda1
Enter passphrase:
incorrect passphrase
Unlock attempt with correct passphrase does not yield error message
"incorrect passphrase". Key seems to be available:
% grep bcachefs /proc/keys
1b9e7153 I--Q--- 1 perm 3f010000 0 0 user bcachefs:[… UUID …]: 32
UUID matches filesystem.
Still I get:
% LANG=en mount /dev/sda1 /mnt/zeit
mount: /mnt/zeit: mount(2) system call failed: Required key not available.
dmesg(1) may have more information after failed mount system call.
% dmesg | tail -1
[105441.695035] bcachefs ([…]): error requesting encryption key: ENOKEY
Why? And how to fix it?
I found
error requesting encryption key #93
https://github.com/koverstreet/bcachefs/issues/93
But I am not sure whether it applies to my situation.
I use Devuan with elogind. Do I need that pam related configuration change

?
I do not like to do it in case it is not required.
Best,
