Stable kernel update 6.6.38

[Posted July 9, 2024 by corbet]

The 6.6.38 stable kernel update has been released, without the benefit of the usual review process. It reverts some BPF changes with patches that do not appear in the mainline (in this form, at least). "All powerpc and arm64 users of the 6.6 kernel series must upgrade. Everyone else probably should as well to be safe."

For the curious, the conversation that led up to this update can be found here. It seems that a hardening patch was not properly backported, leading to Arm64 crashes, but there was some other, unclear problem that created difficulties for PowerPC as well. There was no actual need for those changes in 6.6-stable, so they were simply reverted.

Well it seems it was not properly backported after being automatically flagged for backporting, despite apparently being unnecessary.
