Linux 6.19 changelog.

Summary: Linux 6.19 adds a new listns(2) system call that makes much easier to list the namespaces present on the system; support for the Live Update Orchestrator, which allows to reboot a kernel via kexec while enough kernel state to allow virtual virtual machines continue working after a reboot; support for PCIe Link Encryption which lets PCIe devices encrypt its communication with confidential VMs; Btrfs support for the experimental shutdown ioctl and suspension during scrub or device replaces; Ext4 support for block devices larger than page size and faster online defragmentation; support for the color pipeline API for better and faster HDR graphics; improvements to io_uring; and support for the SFrame format that brings faster frame unwinding. As always, there are many other features, new drivers, improvements and fixes.

1. Prominent features

1.1. New listns(2) system call to list namespaces

There was no direct way for userspace programs on Linux to enumerate namespaces in the system. Applications must resort to scanning /proc/<pid>/ns/ across all processes, which is inefficient, incomplete, permission-heavy, there is no ordering or ownership, no filtering...this release incorporates a new system call, listns(2), which solves these problems by providing direct kernel-level enumeration of namespaces. It is similar to listmount() but tailored to namespaces

1.2. Live update orchestrator

This series introduces the Live Update Orchestrator, a kernel subsystem designed to facilitate live kernel updates using a kexec-based reboot. This has been designed primarily to allows virtual machines to continue working after the reboot with minimal downtime, a capability that is critical for cloud environments, but LUO is designed to be workload-agnostic. LUO achieves these goals by preserving the state of selected resources, such as memory, devices and their dependencies, across the kernel transition.

1.3. Support for PCIe Link Encryption

This release adds support to enable PCIe Link Eencryption and secure Device Authentication. This encryption can be used to communicate confidential VMs (like AMD SEV-SNP or Intel TDX): the PCIe traffic between the VM and the device is encrypted and authenticated on the wire, so the host OS or other devices cannot snoop on DMA traffic, observe or inject data

1.4. Btrfs improvements

This release includes a few important improvements for the Btrfs file system: scrub and device replacement no longer block attempts to suspend the system (scrub records the last state and can continue from there; the device replacement has to be restarted from the beginning); adds support for the shutdown ioctl, improves the (experimental) support for block sizes being larger than the memory page size in RAID56 setups; and it also includes preparations for fscrypt support and some locking performance improvements when the file system is processing space reservation tickets

1.5. Ext4 support for block sizes larger than page size

This release enables support for file system block sizes that are larger than the computer page size (4KB in x86). Larger block sizes have advantages and disadvantages, on the advantage size it can improve buffered IO write performance by about 50% on average (direct IO shows some degradation, due to the increased time spent doing checksums - larger block sizes are not always better). Benchmark details can be found here. This release also optimizes and greatly improves the throughput of online defragment.

1.6. Add color pipeline API, sharpness property, plus other graphic updates

This release adds support in the graphic driver layer for color pipeline. This API supports pre-, and post-blending complex color transformations in display controller hardware in order to allow for HW-supported HDR use-cases, as well as to provide support to color-managed applications, such as video or image editors.

It is possible to support an HDR output on HW, but that requires the compositor or application to render and compose the content into one final buffer intended for display. Doing so is costly. Most modern display hardware supports varios methods to do color transformations, faster and more power efficient than performing similar operations via shaders or CPU. The color pipeline API allows to make use of this hardware functionality to support complex color transformations with no, or minimal CPU or shader load.

There are also other updates done to the graphic layer, such as the sharpness property, which can be set by userspace with desired sharpness strength, which enables adaptive sharpening filter for Intel LNL onwards. There is also a new Arm Ethos NPU accelerator driver, initial Xe3P support in xe, or support in the amdgpu driver for discrete SI/CIK cards (that were previously only support by radeon), which enables vulkan support in userspace for them.

1.7. io_uring updates

As with many other releases, this one includes a few updates to io_uring. This release adds:

- Support for mixed sized SQEs (6.18 added support for mixed sized CQEs, this adds similar support for SQEs, where the occasional need for a 128b SQE doesn't necessitate having all SQEs be 128b in size
- Introduce zcrx and SQ/CQ layout queries. The former returns what zcrx features are available. And both return the ring size information to help with allocation size calculation for user provided rings like IORING_SETUP_NO_MMAP and IORING_MEM_REGION_TYPE_USER - Add support for getsockname and getpeername, which is mostly a trivial hookup after a bit of refactoring on the networking side - Introduce IORING_REGISTER_ZCRX_CTRL and RQ flushing

1.8. SFrame support for faster frame unwinding

The kernel needs to unwind stacks for some tools like perf. One of the most common solutions is to use frame pointers, but that solution degrades performance. Another solution is to use DWARF debugging information, but it's a complex format that it's too slow to parse. There has been work to design a new format, SFrame, which has been implemented by GCC (and LLVM in the future) and binutils. This format contains the minimal information to allow fast stack tracing, and support has been added for it in this release.

2. Core (various)

(FEATURED) Add a new listns(2) system call that allows userspace to iterate through namespaces in the system, similar to listmount(2) but tailored to namespaces. Currently, there is no direct way for userspace to enumerate namespaces in the system. Applications must resort to scanning /proc/<pid>/ns/ across all processes, which is very inconvenient. This system call offers pagination support for large namespace sets, filtering, permission checking, etc (cover), 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, 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

liveupdate
- (FEATURED) Live update orchestrator, a kernel subsystem designed to facilitate live kernel updates using a kexec-based reboot.

Power Management: QoS: Introduce a CPU system wakeup QoS limit for s2idle. Therefore, this series suggests to introduce a new interface for user space, allowing us to specify the CPU system wakeup QoS limit.

coredump: Expose coredump signal via pidfd. Expose the signal that caused the coredump through the pidfd interface. The recent changes to rework coredump handling to rely on unix sockets are in the process of being used in systemd. The previous systemd coredump container interface requires the coredump file descriptor and basic information including the signal number to be sent to the container.

3. File systems

BTRFS
- (FEATURED) Shutdown ioctl support (needs CONFIG_BTRFS_EXPERIMENTAL for now): sets filesystem state as being shut down (also named going down in other filesystems), where all active operations return EIO and this cannot be changed until unmount); pending operations are attempted to be finished but error messages may still show up depending on where exactly the shutdown happened (cover), commit, commit, commit

5. Block layer
