IBM s390 Code For Linux 4.20 Bringing Several Features
Should you be into Linux on z Systems, the IBM s390 code for the Linux 4.20~5.0 cycle is coming with several feature additions.
The s390 code is bringing a few features that have been available on other platforms for a while including KASAN (Kernel Address Sanitizer) as well as support for virtually mapped kernel stacks.
The IBM s390 Linux kernel code also has improved access control around its Zcrypt driver, the pkey API can now provide random protected keys, and a rework to the early boot code.
