KernelNewbies:

• Linux_6.6

Last updated at 2023-11-03 06:34:18

Linux 6.6 has been released on Sunday, 29 Oct 2023.

Summary: This release replaces the CFS process scheduler with a new one called EEVDF, which should provide better latency in general; support for x86 shadow stacks to prevent exploits; support for fs-verity in overlayfs; quotas and xattrs support in tmpfs; more configurable unbound workqueues; faster asynchronous Direct I/O using io_uring; and the first pieces of the XFS online fsck. As always, there are many other features, new drivers, improvements and fixes.

1. Prominent features

1.1. New task scheduler: EEVDF

The task scheduler is the part of the kernel that decides which task should be run next when there are many to pick, its role is critical to achieve good performance and latency. The previous algorithm, called CFS, was merged in Linux 2.6.23. In this release, it is replaced by code that uses a new algorithm, called EEVDF ("Earliest Eligible Virtual Deadline First").

This algorithm is designed to ensure that processes that are not getting the attention they should are automatically picked the next time, while processes that got more than they deserved are "punished". This is done in a clean, algorithmic way, where as CFS used heuristics and tunable knobs to attempt to guess which processes needed more attention. Many of these tunables have been removed. For these reasons, this new scheduler should improve the latency of tasks that would be left behind by CFS while leting other tasks be routinely over-scheduled. For more details, read the LWN article.

1.2. Shadow stacks to prevent exploits

After many years of discussions, the Linux kernel has finally add support for Intel's shadow stack hardware feature. Shadow stack works by maintaining a secondary (shadow) stack that cannot be directly modified. When managing the stack, the processor pushes the return address to both the normal stack and to the special permissioned shadow stack. Upon return, the processor pops the shadow stack copy and compares it to the normal stack copy. If the two differ, the processor raises a control protection fault, which can prevent exploits that were attempting to modify the stack. This implementation supports shadow stack on 64 bit kernels only, with support for 32 bit only via IA32 emulation, and only for userspace.

This release also adds support for Clang's control-flow integrity scheme and randomization of the place where the kernel image is placed on boot in the RISC-V architecture.

1.3. Support for fs-verity in overlayfs

This release adds support in overlayfs for using fs-verity to validate lowerdata files by specifying an overlay.verity xattr on the metacopy files. This is primarily motivated by the Composefs usecase, where there will be a read-only EROFS layer that contains redirect into a base data layer which has fs-verity enabled on all files. However, it is also useful in general if you want to ensure that the lowerdata files matches the expected content over time.

For more information, read the Documentation

1.4. Quotas and xattrs support in tmpfs

This release adds user and group quotas to tmpfs (project quotas will be added later). It also adds support for user xattrs (security xattrs and POSIX ACLs are alreadys supported) and support for stable directory offsets.

1.5. More configurable unbound workqueues

Workqueues are used by other parts of the kernel to defer some work that will be run asynchronously. There are various types, unbound workqueues are work items that are not bound to any specific CPU and they were usually spread inside each NUMA node, which isn't great when many unbound items are created on some modern CPUs (especially arm64) with multiple L3 caches. This release attempts to improve the CPU locality awareness of these items. Unfortunately there exists a pronounced trade-off between locality and utilization necessitating explicit configurations when workqueues are heavily used, thus some configuration knobs are available to achieve the best result for all types of hardware. The default behavior is to soft-affine according to last level cache boundaries. On machines which multiple L3 caches, which are becoming more popular along with chiplet designs, this improves cache locality while not harming work conservation too much.

1.6. Faster asynchronous Direct I/O using io_uring

When using io_uring to do asynchronous direct I/O, this release can improve performance significantly, up to a 37% improvement in throughput/latency for low queue depth IO.

1.7. First pieces of XFS online fsck

In order to achieve maximum reliability, XFS is aiming to be able to fix itself without unmounting the file system. This release includes the first infrastructure pieces that will allow this feature in next releases.

2. Core (various)

• (FEATURED) Control-flow Enforcement: Shadow Stack for userspace commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• (FEATURED) workqueue: Improve unbound workqueue execution locality. Unbound workqueues spray work items inside each NUMA node, which isn't great on CPUs w/ multiple L3 caches. This release implements mechanisms to improve and configure execution locality. For more details see this recommended LWN article, and the Documentation commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• cgroup/cpuset: A new cpuset control file cpuset.cpus.exclusive (read-write) and a cpuset.cpus.exclusive.effective (read only) file are added for better control of which exclusive CPUs are being distributed down the cgroup hierarchy for creating cpuset partition. Any one of the exclusive CPUs can only be distributed to at most one child cpuset. This release also introduces a new category of cpuset partition called remote partitions. The existing partition category where the partition roots have to be clustered around the root cgroup in a hierarchical way is now referred to as local partitions. A remote partition can be formed far from the root cgroup with no partition root parent. The container management tool can manage the cpuset.cpus.exclusive file without impacting the other cpuset files that are managed by other middlewares commit, commit, commit, commit

• SMT: So far the sysfs SMT control only allows to toggle between SMT on and off.
