cryptsetup: set the default luks format to LUKS1
The cryptsetup 2.1 uses LUKS2 format as the default LUKS format. This
change introduced the following issues:
* LUKS2 requires kernel userspace crypto API to be available
(CONFIG_CRYPTO_USER_API and CONFIG_CRYPTO_USER_API_SKCIPHER). But
linux-yocto doesn't enable these options by default. If missing these
kernel modules, the cryptsetup will fall back to using dmcrypt-device
for keyslot processing.
$ cryptsetup --debug --type luks luksFormat /dev/sda3
[snip]
Checking if cipher aes-xts-plain64 is usable.
Userspace crypto wrapper cannot use aes-xts-plain64 (-95).
Using dmcrypt to access keyslot area.
[snip]
* The grub can not decrypt a LUKS2 encrypted boot partition because it
doesn't support LUKS2 now.
See grub bug: https://savannah.gnu.org/bugs/?55093
Add a PACKAGCONFIG for luks format and set the default LUKS format to
LUKS1. The users can specify '--type luks2' in cryptsetup command line
if they want to use LUKS2.
