Linux 6.15 Device Mapper Brings Inline Crypto Passthrough For DM-Stripe
All of the Device Mapper “DM” changes have been merged to mainline for the in-development Linux 6.15 kernel.
One of the notable DM changes this cycle is adding support for inline crypto passthrough to dm-stripe, the striped target for Device Mapper to provide RAID-0 like functionality across storage devices. With inline crypto support, it allows making use of hardware encryption of the underlying storage device(s) where capable. A lot of ARM hardware in particular supporting inline encryption hardware and being quite helpful for performance.
The dm-crypt code for Linux 6.15 has switched to using the common CRC32 library. In making use of the common CRC32 library function, it’s easier to take advantage of architecture-specific…
