With the Linux 6.6 merge window over, here's a look at the most interesting new features, hardware support, and other changes to find with this kernel that will debut as stable around the end of October. Linux 6.6 is another exciting kernel from new software innovations to recent and upcoming hardware support.

The Intel Shadow Stack support that is part of their Control-flow Enforcement Technology (CET) has finally been merged for the Linux 6.6 kernel after it was previously rejected by Linus Torvalds.

Intel engineers had sent in Shadow Stack support for Linux 6.4 as this feature part of Control-flow Enforcement Technology (CET) but it hit a last-minute snag during the merge window with issues raised by Linus Torvalds

Since Linux 5.18 there has been Indirect Branch Tracking (IBT) in the mainline kernel that was contributed by Intel as part of their Control-flow Enforcement Technology (CET)

With Linux 6.4-rc1 released, here is my original overview of all the interesting changes coming for the Linux 6.4 kernel that will be released as stable at the end of June or in early July. As the Linux 6.4 merge window is over, it's time to begin testing this new kernel (and in my case, benchmarking it for any interesting improvements or regressions) over the next roughly eight weeks.

Intel Shaodw Stack support was submitted for Linux 6.4 at the start of the merge window but now with this two-week merge window drawing to a close, it hasn't been pulled yet and Linus Torvalds raised technical issues with the proposed patches that now jeopardize its arrival this cycle.

While Intel Shadow Stack support has been around since Tiger Lake CPUs as part of Intel's Control-flow Enforcement Technology (CET), finally for the Linux 6.4 kernel is this security feature being enabled with the mainline Linux kernel.

IT teams need to rethink their approach to security under our new working models

In a changing working world, the need for security is greater than ever.
