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.

Recommended paper: Earliest Eligible Virtual Deadline First : A Flexible and Accurate Mechanism for Proportional Share Resource Allocation
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.
Recommended LWN article: User-space shadow stacks
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.
Recommended LWN article: A pair of workqueue improvements
Documentation: Workqueues: Affinity scopes
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.
For more details, read the XFS online fsck design document
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. This release expands the sysfs interface and the core infrastructure to accept numerical values so some platforms, like PowerPC, can build SMT runtime control for partial SMT enablement on top commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

7. Tracing, perf
tracing: introducing eventfs. This is the code that handles the inodes and dentries of tracefs/events directory. As there are thousands of events, and each event has several inodes and dentries that currently exist even when tracing is never used, they take up precious memory. Instead, eventfs will allocate the inodes and dentries in a JIT way (similar to what procfs does) commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
