Bug#926533: linux-image-armmp-lpae: Fail to mount cryptsetup device: missing aes-xts-plain64 cipher

[Lars Kruse <devel@sumpfralle.de>]

Package: linux-image-armmp-lpae
Version: 4.19+104
Severity: normal

Dear Maintainer,

after upgrading from 4.9.144-3 to 4.19+104 I am not able to mount
cryptsetup devices anymore.

  # cryptsetup luksOpen /dev/lvm-foo/crypto foo
  Enter passphrase for /dev/lvm-foo/crypto: 
  device-mapper: reload ioctl on   failed: No such file or directory
  Failed to setup dm-crypt key mapping for device /dev/lvm-foo/crypto.
  Check that kernel supports aes-xts-plain64 cipher (check syslog for more
  info).
  device-mapper: remove ioctl on temporary-cryptsetup-3150  failed: No
  such device or address
  device-mapper: table ioctl on   failed: No such device or address


The output of dmesg is:
  device-mapper: table: 253:8: crypt: Error allocating crypto tfm
  device-mapper: ioctl: error adding target to table


The respective LUKS header of the cryptsetup device looks like this:

  # cryptsetup luksDump /dev/lvm-foo/crypto 
  LUKS header information for /dev/lvm-foo/crypto
  Version:        1
  Cipher name:    aes
  Cipher mode:    xts-plain64
  Hash spec:      sha1
  Payload offset: 4096
  MK bits:        256
  ...


Maybe the lack of the "aes-xts-plain64" cipher is related to the following?

  # dpkg -L linux-image-4.9.0-8-armmp-lpae | grep aes
  /lib/modules/4.9.0-8-armmp-lpae/kernel/drivers/crypto/omap-aes.ko
  # dpkg -L linux-image-4.19.0-4-armmp-lpae | grep aes
  [no output]


I am using a BananaPi M1 board.

Thank you for your time!

Cheers,
Lars
