Kernel 6.13 Release Information

https://kernelnewbies.org/Linux_6.13

Linux 6.13 has been released on Sunday, 19 Jan 2025.

Summary: This release includes a new lazy preemption model that provides more preemption opportunities than the voluntary preemption mode used often as default, but not as many as the full preemption mode. There is also support for fine-grained timestamps, without the performance overhead that would often come with providing high-resolution timestamps for every single file; lightweight guard pages; support for storage with atomic writes in XFS and Ext4; support for NAPI suspension during idle periods; a new networking device API to configure TX H/W shaping; various io_uring improvements; ARM support for running Linux in a protected VM under the Arm Confidential Compute Architecture; ARM support for user-space shadow stacks; and a referenced counting mechanism for files that is slightly more scalable. As always, there are many other features, new drivers, improvements and fixes. Also, you might be interested in the LWN merge window report: part 1, part 2

Contents

1. Prominent features

1.1. Lazy preemption: a bit more of preemption

The Linux kernel support four different preemption modes. There is a “full preemption” mode, but since preemption is usually at odds with performance, most Linux kernels default to using the “voluntary preemption” mode, which provides some preemption opportunities, but it’s not full preemption.

This release adds a “lazy preemption” mode that aims to be a bridge between the voluntary and the full preemption mode. It optimizes fair-class preemption by delaying preemption requests to the tick boundary, while working as full preemption for RR/FIFO/DEADLINE classes.

1.2. Support for multi-grain file timestamps: fine-grained timestamps, without the performance overhead

Some applications (notably, NFS) need higher-resolution timestamps on files, but higher resolution timestamps on all files can increase the rate at which metadata needs to be written to the disk. In this release, Linux adds support for fine-grained timestamps, but only when processes do query that information for a file. This allows for finer-grained timestamps without the performance overhead.

Documentation: Multigrain Timestamps

1.3. Support for atomic writes

There is some hardware that supports atomic write operations, by which we mean writes to write data that is larger than the storage’s sector size in an atomic way. This release adds support for atomic writes in XFS, Ext4’s Direct I/O, and some md RAID modes.

Recommended LWN article: Atomic writes without tears

1.4. NAPI suspension for more efficient networking

Interrupt mitigation in networking loads can be accomplished with busy polling, and can be quite efficient, but it cannot effectively support both low- and high-load situations.

This release adds a new packet delivery mode that properly alternates between busy polling and interrupt-based delivery depending on busy and idle periods of the application. During a busy period, the system operates in busy-polling mode, which avoids interference. During an idle period, the system falls back to interrupt deferral, but with a small timeout to avoid excessive latencies

1.5. New networking device API to configure TX H/W shaping

There is a plurality of shaping-related drivers API, but none flexible enough to meet existing demand from vendors. This release introduces new device APIs to configure in a flexible way TX H/W shaping. The new functionalities are exposed via a newly defined generic netlink interface and include introspection capabilities.

API documentation: Family net-shaper netlink specification

1.6. Lightweight guard pages

A guard page is a page that, when accessed, cause a fatal signal to arise. Installing a guard page in certain places can be useful in various situations. Currently users must establish PROT_NONE ranges to achieve this, but this is costly memory-wise - it needs a VMA for each and every one of these regions AND they become unmergeable with surrounding VMAs

This release implements a MADV_GUARD_INSTALL flag for the madvise() system call which implements a guard page, but without that overhead, thus making it cheaper and easier to use these pages.

1.7. Various io_uring improvements

This release adds support for various io_uring features:

Add support for ring resising, so apps can start with a small ring and grow it as needed
Support for sending a sync message to another ring, without having a ring available to send a normal async message
Add support for just doing partial buffer clones, rather than always cloning the entire buffer table
Add support for fixed wait regions, rather than needing to copy the same wait data tons of times for each wait operation
Add static NAPI support, where a specific NAPI instance is used rather than having a list of them available that need lookup
Regions, param pre-mapping and reg waits extension: it’s a better and more generic API for ring/memory/region registration, and it changes the API extending registered waits to be a generic parameter passing mechanism. That will be useful in the future to implement a more flexible rings creation, especially when we want to share same huge page / mapping
Add support for hybrid IO polling, which is a variant of strict IOPOLL but with an initial sleep delay to avoid spinning too early and wasting resources on devices that aren’t necessarily in the < 5 usec category wrt latencies

1.8. ARM64 virtualisation and security improvements

This release adds support in the ARM architecture for:

Running Linux in a protected VM under the Arm Confidential Compute Architecture (CCA) (Arm Confidential Compute Architecture documentation)
Support for Guarded Control Stack in userspace (ARM’s implementation of shadow stacks), which provides support for hardware protected stacks of return addresses, intended to provide hardening against return oriented programming (ROP) attacks and to make it easier to gather call stacks for applications such as profiling.

1.9. Reference counting mechanism for more scalable file operations

This release introduce a new reference counting mechanism for files. It gives consistent improvement up to 3-5% on workloads with loads of threads

2. Core (various)

(FEATURED) Lazy preemption commit, commit, commit, commit
cgroup: Exposing nice CPU usage to userspace commit, commit
fanotify: allow reporting errors on failure to open fd commit
fcntl: make F_DUPFD_QUERY associative commit
Add fs.dentry-negative sysctl for automated deletion of dentry, this sets the policy for negative dentries, and whether to always delete the dentry when a file is removed or not, since this can affect performance commit
fs/file.c: optimise the critical section of file_lock in commit, commit, commit
Add the four syscalls setxattrat(), getxattrat(), listxattrat() and removexattrat(). Those can be used to operate on extended attributes, especially security related ones, either relative to a pinned directory or on a file descriptor without read access, avoiding a /proc//fd/ detour, requiring a mounted procfs. Part of a small-scale attempt at sanitising the interplay between io\_uring and normal syscalls [commit](https://git.kernel.org/linus/5b313bcb6e3597dacd893ae9545fd087df46db45), [commit](https://git.kernel.org/linus/e896474fe4851ffc4dd860c92daa906783090346), [commit](https://git.kernel.org/linus/dc7e76ba7a6057e4c12d449db49f026d0ec238ec), [commit](https://git.kernel.org/linus/b8cdd2530c7d7156413c5dfc1f4bc83c1d26b446), [commit](https://git.kernel.org/linus/a71874379ec8c6e788a61d71b3ad014a8d9a5c08), [commit](https://git.kernel.org/linus/537c76629d7855ce11400eaad0137a062bfc15f6), [commit](https://git.kernel.org/linus/a10c4c5e01bdab617eaf3aaac9a96c22ddefa97e), [commit](https://git.kernel.org/linus/66d7ac6bdb07fbe69ca6971558a996ac04bbb643), [commit](https://git.kernel.org/linus/0158005aaa3c946ecac9d251c34708a40a85cbe1), [commit](https://git.kernel.org/linus/60ad149cf395ff0a502976963d9a89c2f5dfe424), [commit](https://git.kernel.org/linus/22a4d1954cf5d51d5aa82eccb0b5fd4d8be92551), [commit](https://git.kernel.org/linus/6140be90ec70c39fa844741ca3cc807dd0866394), [commit](https://git.kernel.org/linus/46a7fcec097da5b3188dce608362fe6bf4ea26ee)

4. Memory management

Page allocation tag compression. This provides an option to store page allocation tag references in the page flags, removing dependency on page extensions and eliminating the memory overhead from storing page allocation references (~0.2% of total system memory). This also improves page allocation performance when CONFIG_MEM_ALLOC_PROFILING is enabled by eliminating page extension lookup.

12.2. Power Management

Add thermal user thresholds support, which is a way to have the userspace to tell the thermal framework to send a notification when a temperature limit is crossed. There is no id, no hysteresis, just the temperature and the direction of the limit crossing. That means we can be notified when a threshold is crossed the way up only, or the way down only or both ways. That allows to create hysteresis values if it is needed. commit, commit, commit, commit, commit

amd-pstate: Make amd-pstate the default driver on server platforms commit, commit
Add a virtualised cpufreq driver for guest kernels that read/writes to a MMIO region for a virtualised cpufreq device to communicate with the host. It sends performance requests to the host which gets used as a hint to schedule vCPU threads and select CPU frequency. If a VM does not support a virtualised FIE such as AMUs, it updates the frequency scaling factor by polling host CPU frequency to enable accurate Per-Entity Load Tracking for tasks running in the guest commit, commit
