Hi, I recently configured dm-crypt + dm-integrity on an iMX6q platform with CAAM Hash functions enabled using the following command lines : Linux 4.14.71 cryptsetup luksFormat /dev/mmcblk1p3 --cipher aes-xts-plain64 --type luks2 --integrity hmac-sha256 --sector-size 512 --use-urandom cryptsetup open /dev/mmcblk1p3 root mkfs.ext4 -v -F /dev/mapper/root luksFormat and open finishes correctly, luksDump and status reports correct dm and luks properties. but when trying to access the /dev/mapper/root (mkfs, sha256sum or whatever), it blocks without any warning or errors reported by the kernel. I can see a few (~170) interrupts on the jr0 interrupt then nothing. Is there a particular issue with hmac-sha256 with the linux CAAM driver ? When disabling the CAAM hash functions or using another cipher & integrity pair, it works like a charm.
