On 19 Oct 2019 13:44 +0200, from 400thecat@xxxxxx (Fourhundred Thecat): >> This is the first problem - why you do not have kernel userspace crypto API enabled? > > What is the name of the CONFIG_ option of the kernel userspace crypto API ? https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/crypto/Kconfig?h=v4.14.146#n16 indicates that it should be CONFIG_CRYPTO. You'll probably need some others as well, depending on how you actually plan to use LUKS. At an absolute minimum, I would expect you'd need one of the CONFIG_CRYPTO_AES variants as well as CONFIG_CRYPTO_SHA1 when running the LUKS utilities with defaults (AES, SHA1). >>> # Udev is not running.

(Again, it should work but it is quite problematic situation.) > > I am using the "kernel udev" > CONFIG_DEVTMPFS > CONFIG_DEVTMPFS_MOUNT No, CONFIG_DEVTMPFS is independent of udev. Note the kernel configuration help text on CONFIG_DEVTMPFS, which says in part: # It [the devtmpfs file system] provides a fully functional /dev directory, where usually # udev runs on top, managing permissions and adding meaningful # symlinks. # In very limited environments, it may provide a sufficient # functional /dev without any further help. It also allows simple # rescue systems, and reliably handles dynamic major/minor numbers. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/base/Kconfig?h=v4.14.146#n29 Note the _where usually udev runs on top_ and _very limited environments_ and _may_. That's quite a few caveats already in those two sentences. Of course, nothing says you absolutely _have_ to use udev, or build a kernel with everything and the kitchen sink, but you're kind of going against the stream by having a highly unusual system configuration (especially if it's also a minimal configuration), and should expect to have to put in more effort in such a situation than if you were running a more common configuration. -- Michael Kjörling • https://michael.kjorling.se • michael@xxxxxxxxxxx “The most dangerous thought that you can have as a creative person is to think you know what you’re doing.” (Bret Victor) _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx https://www.saout.de/mailman/listinfo/dm-crypt
