KernelNewbies:

• Linux_6.4

Last updated at 2023-08-24 19:29:35

Linux 6.4 was released on Sun, 25 Jun 2023.

Summary: This release includes support for Intel's Linear Address Masking; stall pressure information can be polled by unprivileged users; a API for User-space trace events has been added; safer Kernel Samepage Merging with a new process/cgroup API; more scalable memory management with per-VMA locks and faster context switching between user and kernel threads, new BPF features, and removal of the SELinux runtime disable capability. As always, there are many other features, new drivers, improvements and fixes.

1. Prominent features

1.1. Enable Intel's Linear Address Masking

Enable Address Masking on Intel chips. This is similar to ARM's Top Byte Ignore and allows userspace to use some bits of pointers without masking it out before use, allowing sofware to use these untranslated address bits for metadata. The capability can be used for efficient address sanitizers (ASAN) implementation and for optimizations in JITs and virtual machines

Recommended LWN article: Support for Intel's Linear Address Masking

1.2. Unprivileged Pressure Stall Information

This release allows for unprivileged PSI polling, which allow unprivileged tools to provide this information to users.

1.3. New API for User-space trace events

A new API has been added for user-space trace events. In this new model during the event registration from user programs 3 new values are specified. The first is the address to update when the event is either enabled or disabled. The second is the bit to set/clear to reflect the event being enabled. The third is the size of the value at the specified address

Recommended LWN article: User trace events, one year later.

1.4. Safer Kernel Samepage Merging with a new process/cgroup API

So far KSM can only be enabled by calling madvise() for memory regions, but this API is too insecure. To be able to use KSM for more workloads, KSM needs to have the ability to be enabled and disabled at the process / cgroup level. This release adds two new options to the prctl system call. The first one allows to enable KSM at the process level and the second one to query the setting

1.5. More scalable memory management with per-VMA locks

The memory management subsystem has added a new kind of locks in each VMA (Virtual Memory Area, a data structure that representes virtual memory) which means that some operations will no longer use the mmap_lock. This improves scalability in a number of scenarios. For example, startup of Android apps with a large number of threads.

1.6. More scalable context switching between user and kernel threads

This release improves scalability of context switching between user and kernel threads on large systems with a threaded process spread across a lot of CPUs

This takes lazy tlb mm shootdown IPI interrupts from 314 to 3 on a 144 POWERPC CPU system doing a kernel compile.

1.7. New BPF features

As usual, this release brings new

BPF open-coded iterators, support for kptrs in more BPF maps, kptr RCU, shared ownership for local kptrs, support 64-bit pointers to kfuncs, or first class support for attaching uprobes to functions inside ELF objects containers in Android APKs.

1.8. Removal of the SELinux runtime disable capability

For security reasons, the ability to diable SELinux at runtime has been removed.

2. Core

• (FEATURED) PSI: Allow unprivileged PSI polling commit, commit, commit, commit

• io_uring

  • User mapped provided buffer rings commit, commit, commit, commit, commit

  • Take advantage of completion batching for uring commands commit

• task scheduler

  • Interleave cfs bandwidth timers for improved single thread performance at low utilization commit

  • Reduce cost of sched_move_task when config autogroup commit

3. File systems

3.1. BTRFS

• Improve logging changes in a directory during one transaction, avoid iterating over items and reduce lock contention (fsync time 4x lower) commit

• Convert pagecache_read() to use a folio commit

3.5. F2FS
