Crypto: Error allocating crypto after system update

mindwar · 2021-01-09 19:47:30

I am hoping someone can help me. I'm afraid I may have lost all of my data since the drive is encrypted. I recently updated my system and upon reboot I am receiving "device-mapper: table: 254.0: crypt: Error allocating crypto tfm device-mapper: reload ioctl on failed: no such file or directory". The system is setup to use anubis chiper. Any ideas on what happened during the update? When I mount the boot partition, there is nothing there. It's as if it was deleted.

Please post the pacman.log for the update. Are you sure you mounted the correct partition? The system loaded the kernel from somewhere.

I can't access the pacman.log as the entire system is encrypted.

I tried mounting the encrypted partition separately, and I am receiving the same error. It appears something about the partition is damaged... so there goes 20 years of data. What the fuck could possibly have happened during an update to damage a partition?

Correlation is not causation.

Can you boot the falback initramfs?

I cannot boot the fallback at all.

I have 3 different kernels installed. Zen, LTS, and regular. None are working and neither are the fallbacks. I can't even load it using an archlinux bootable ISO. Is it possible support has been removed for anubis across all of the kernels?

What confuses me is that I cannot even attempt to use the same chiper and hash on the partition as if I were creating a new encrypted partition using dm-crypt from the latest bootable arch ISO. SOmething has definitely changed with support.

Well, it is not in 5.10.5 https://github.com/archlinux/svntogit-p … nfig#L9540

But it is a module in LTS: https://github.com/archlinux/svntogit-p … fig#L10077

ANUBIS support has been deprecated in the kernel see https://cateee.net/lkddb/web-lkddb/CRYPTO_ANUBIS.html / https://cateee.net/lkddb/web-lkddb/CRYP … OLETE.html

Alright, so I was able to use an older computer that has not been updated in awhile to mount it at least. My plan is to make a dd image of the partition unencrypted then recreate it in the arch ISO using another cipher and reimage it. Hopefully that will work.
