Linux 6.12-rc5 Disabling Intel's Linear Address Masking "LAM" Due To Security Concerns

([Linux Kernel] 27 October 07:30 AM EDT Linear Address Masking)

Intel merged Linear Address Masking into the Linux kernel last year as a means of allowing user-space to store metadata within some bits of pointers without masking it out before use. LAM can be useful for virtual machines, sanitizers / profiling / memory tagging, and other uses. While the brand new Intel Arrow Lake and Lunar Lake CPUs support LAM, the Linux kernel is now disabling LAM out of security concerns.



Intel's PCIe Cooling Driver Ready For Linux 6.13 To Reduce Bandwidth When Running Hot

FUTEX2 NUMA & Small Futexes Revived For Linux

([Linux Kernel] 25 October 06:55 AM EDT FUTEX2 NUMA + Small Futex)

Back in 2020~2021 there was lots of talk and work around FUTEX2 for improving the Linux kernel's Futex implementation for fast user mutex. The FUTEX2 work was driven in large part for helping Steam Play / Wine gaming by better matching the behavior of Microsoft Windows with its WaitForMultipleObjects handling. While the initial code landed back in Linux 5.16, there's been other remaining FUTEX2 features still desired like variable-sized futexes and NUMA-awareness. Finally now we're seeing that work revived.
