dm-crypt issues, can we get it as a module #22

Open nikias opened 4 years ago

Hi, when I try to mount a luks volume, I am getting this error:

device-mapper: table: 253:0: crypt: unknown target type
device-mapper: reload ioctl on   failed: Invalid argument

According to my researches, this bug can be resolved by providing dm-crypt as a kernel module instead of built-in. Could you update the build to reflect that? That would be pretty dope :) Thanks

Can you tell which kernel? I think kernel 5.x i have # CONFIG_DM_CRYPT is not set

Would you mind trying 5.9.0-rc3? I am testing it with 20.04 LTS.

Oh sorry, I was talking about 5.7.9 - if it's not set then obviously it can't work at all. I might give it a shot with 5.9.0-rc3.

We have it as a modules now:

 LD [M]  drivers/md/dm-crypt.ko
  LD [M]  crypto/essiv.ko

Please try this one, I did it in a rush and had no time to test but should work. If you prefer the img file it will take some time.
