Key points
- Linux 7.4 kernel crypto library gains optimized AES implementations for x86 and RISC-V
- Optimized AES implementations include ECB, CBC, CBC-CTS, CTR, XCTR, and XTS modes
- Optimized implementations now use AVX optimized code and AES-NI instructions on x86_64 CPUs
- Stian Halseth's optimized AES-XTS implementation for SPARC64 is now available
- The full list of crypto library updates for Linux 7.4 can be found in this pull request
These optimizations could make systems more secure and faster, especially for computers that use Intel or AMD chips.
There might be some small issues with the new optimizations, but overall it should be a good thing for Linux.
