QCOM SDCC controller having Inline Crypto Engine support Inline Crypto Engine do encryption/decryption on fly. dm-inlinecrypt driver will be use to do encryption/decryption with Inline Crypto Engine. v2: * Added new driver dm-inlinecrypt * Dropped patch "md: dm-crypt: Set cc->iv_size to 4 bytes" * squash patch "blk-crypto: Add additional algo modes for Inline" encryption and patch "md: dm-crypt: Add additional algo modes for inline encryption" to the dm-inlinecrypt driver. * tested with dmsetup command as below dmsetup create test-crypt --table '0 251904 inline-crypt aes128-xts- plain a7f67ad520bd83b9725df6ebd76c3eeea7f67ad520bd83b9725df6ebd76c3eee 0 /dev/mmcblk0p27 0 1' dd if=/dev/urandom of=/tmp/data bs=1M count=1 dd if=/tmp/data of=/dev/mapper/test-crypt bs=1M count=1 dd of=/tmp/data1 if=/dev/mapper/test-crypt bs=1M count=1 dd of=/tmp/data2 if=/dev/mmcblk0p27 bs=1M count=1 md5sum /tmp/data* b45d728bfb499b6de9b12c98fbb652dd /tmp/data b45d728bfb499b6de9b12c98fbb652dd /tmp/data1 bc4107e19cf6fc012c5b997bdd3f0de4 /tmp/data2 dmsetup remove /dev/mapper/test-crypt v1: * This series of patches add additional modes for inline encryption This series of patches depends on [1] Add inline encryption support for dm-crypt [1]: https://lore.kernel.org/all/b45d3b40-2587-04dc-9601-a9251dacf806@xxxxxxxxxxxxxxxxxx/T/#ma01f08a941107217c93680fa25e96e8d406df790 * These patches tested on IPQ9574 with eMMC ICE for raw partition encryption/decryption. e.g: dmsetup create test-crypt --table '0 251904 crypt aes128-xts-plain64 a7f67ad520bd83b9725df6ebd76c3eeea7f67ad520bd83b9725df6ebd76c3eee 0 /dev/mmcblk0p27 0 1 inline_crypt' dd if=/dev/urandom of=/tmp/data bs=1M count=1 dd if=/tmp/data of=/dev/mapper/test-crypt bs=1M count=1 dd of=/tmp/data1 if=/dev/mapper/test-crypt bs=1M count=1 dd of=/tmp/data2 if=/dev/mmcblk0p27 bs=1M count=1 md5sum /tmp/data* b45d728bfb499b6de9b12c98fbb652dd /tmp/data b45d728bfb499b6de9b12c98fbb652dd /tmp/data1 bc4107e19cf6fc012c5b997bdd3f0de4 /tmp/data2 dmsetup remove /dev/mapper/test-crypt Md Sadre Alam (3): dm-inlinecrypt: Add inline encryption support mmc: cqhci: Add additional algo mode for inline encryption mmc: sdhci-msm: Add additional algo mode for inline encryption block/blk-crypto.c | 21 +++ drivers/md/Kconfig | 8 + drivers/md/Makefile | 1 + drivers/md/dm-inline-crypt.c | 316 ++++++++++++++++++++++++++++++++ drivers/mmc/host/cqhci-crypto.c | 12 ++ drivers/mmc/host/sdhci-msm.c | 10 +- drivers/soc/qcom/ice.c | 65 ++++++- include/linux/blk-crypto.h | 3 + 8 files changed, 419 insertions(+), 17 deletions(-) create mode 100644 drivers/md/dm-inline-crypt.c -- 2.34.1
