[PATCH 0/6] Basic inline encryption support for ufs-exynos

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add support for Flash Memory Protector (FMP), which is the inline
encryption hardware on Exynos and Exynos-based SoCs.

Specifically, add support for the "traditional FMP mode" that works on
many Exynos-based SoCs including gs101.  This is the mode that uses
"software keys" and is compatible with the upstream kernel's existing
inline encryption framework in the block and filesystem layers.  I plan
to add support for the wrapped key support on gs101 at a later time.

Tested on gs101 (specifically Pixel 6) by running the 'encrypt' group of
xfstests on a filesystem mounted with the 'inlinecrypt' mount option.

This patchset applies to v6.10-rc3, and it has no prerequisites that
aren't already upstream.
