Changes done in each Linux kernel release. Other places to get news about the Linux kernel are LWN kernel status or the Linux Kernel mailing list (there is a web interface in www.lkml.org or lore.kernel.org/lkml). The lore.kernel.org/lkml/ archive is also available via NTTP if you prefer to use a newsreader: use nntp://nntp.lore.kernel.org/org.kernel.vger.linux-kernel for that. List of changes of older releases can be found at LinuxVersions. If you're going to add something here look first at LinuxChangesRules!

You can discuss the latest Linux kernel changes on the New Linux Kernel Features Forum.

1. Prominent features

1.1. Support recursive id-mapped mounts

Linux 5.12 added support for id-mapped mounts, that is, creating a mount of an existing file system with the user and group IDs mapped to different ones. This is very useful for containers, where you might want to mount a directory with some random user ID as the user ID expected by the container. This feature, however, required that the base file system was a file system that was not id-mapped itself. This release supports recursive id-mapped mounts.

1.2. BPF CO-RE support and other improvements

The nature of BPF programs makes hard for them to be portable: The position of a member in a data structure can change depending from version to version and even on the same kernel depending on the compiler options. This requires compiling BPF programs in the target computer. In order to make BPF programs more portable, a few features are required; some have already been merged, like BTF, which was introduced in Linux 4.18 and provides type information of all kernel data structures. This release introduces "CO-RE" -Compile Once, Run Everywhere- support. Along with other pieces in the userspace BPF infrastructure, this helps to create BPF programs that can be run in different kernels without requiring compilation.

Recommended article: BPF CO-RE reference guide.

This release also adds the bpf_loop helper, which helps to move loop logic of BPF programs into the kernel and thereby guarantee that the loop will always terminate

1.3. New P-State driver for modern AMD cpus

This release includes a new AMD P-State driver. AMD P-State is the AMD CPU performance scaling driver that introduces a new CPU frequency control mechanism on AMD Zen based CPU series in Linux kernel. The new mechanism is based on Collaborative Processor Performance Control (CPPC) which is finer grain frequency management than legacy ACPI hardware P-States. Current AMD CPU platforms are using the ACPI P-states driver to manage CPU frequency and clocks with switching only in three P-states. AMD P-State leverages the Linux kernel governors such as schedutil, ondemand, etc. to manage the performance hints which are provided by CPPC hardware functionality. AMD P-State is supported on recent AMD Zen base CPU series include some of Zen 2 and Zen 3 processors.

1.4. Random number generator improvements

This release switches the entropy extractor in the RNG from SHA-1 to BLAKE2s. This change improves the backtracking security from 80 bits to 128 bits. Some additional changes have also drastically improved performance.

1.5. Rewrite of the networking caching backend for networking file systems

Linux networking file systems (e.g. NFS) can optionally use a networking cache layer called fscache and cachefiles. This layer has been rewritten in this release, significantly simplifying the code compared to what's upstream, removing the complex operation scheduling and object state machine in favour of something much smaller and simpler

1.6. New Real-Time Linux Analysis (RTLA) tool

As part of the efforts to get PREEMPT_RT into mainline, this release includes a Real-Time Linux Analysis (RTLA) tool. rtla is a meta-tool that includes a set of commands that aims to analyze the real-time properties of Linux. But instead of testing Linux as a black box, rtla leverages kernel tracing capabilities to provide precise information about the properties and root causes of unexpected results, making it easier for users and developers to collect performance and trace data, and helping fine-tune their systems/algorithms.

1.7. New fanotify FAN_RENAME flag

This release adds a FAN_RENAME event to the fanotify interfaces to report extra info records about new and old parent+name details. This new event was designed as a replacement for the "inotify way" of joining the MOVED_FROM/MOVED_TO events using a cookie

1.8. Support giving names to anonymous memory

Anonymous memory (not backed by a file, e.g. malloc) is, as the name says, anonymous, and it's not easy to debug anonymous memory usage coming from various system components. This release allows to give a name to anonymous memory mappings. It adds a field to /proc/pid/maps and /proc/pid/smaps to show a userspace-provided name for anonymous vmas. The names of named anonymous vmas are shown as [anon:<name>]. Userspace can set the name for a region of memory by calling prctl(PR_SET_VMA, PR_SET_VMA_ANON_NAME, start, len, (unsigned long)name);.

1.9. Mitigate straight-line speculation attacks

4. Memory management

Convert much of the page cache to use folios, but still don't enable it 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
Separate struct slab from struct page - an offshot of the page folio work. Struct page fields used by slab allocators are moved from struct page to a new struct slab, that uses the same physical storage. Similar to struct folio, it always is a head page. This brings better type safety, separation of large kmalloc allocations from true slabs, and cleanups 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
Extend vmalloc support for constrained allocations commit, commit, commit, commit
(FEATURED) Support for anonymous VMA naming. It adds a field to /proc/pid/maps and /proc/pid/smaps to show a userspace-provided name for anonymous vmas. The names of named anonymous vmas are shown as [anon:<name>]. Userspace can set the name for a region of memory by calling prctl(PR_SET_VMA, PR_SET_VMA_ANON_NAME, start, len, (unsigned long)name);.

damon
- schemes: Extend stats for better online analysis and tuning commit, commit, commit, commit, commit, commit
- Add access checking for hugetlb pages commit
Adds set_mempolicy_home_node syscall to set a home node for the MPOL_BIND and MPOL_PREFERRED_MANY memory policy. Users should use this syscall after setting up a memory policy for the specified range. The syscall allows specifying a home node/preferred node from which kernel will fulfill memory allocation requests first. This helps applications to hint at a memory allocation preference node and fallback to _only_ a set of nodes if the memory is not available on the preferred node. Fallback allocation is attempted from the node which is nearest to the preferred node commit, commit, commit

md: drop queue limitation for RAID1 and RAID10 commit
Remove the rsxx driver commit

6. Tracing, perf and BPF

Add rtla(1) tool, a meta-tool including a set of commands that aims to analyze the real-time properties of Linux. But instead of testing Linux as a black box, rtla leverages kernel tracing capabilities to provide precise information about the properties and root causes of unexpected results. In this release it presents an interface to the osnoise and timerlat tracers. In the future, it will also serve as home to the rtsl and other latency/noise tracers commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
BPF
- (FEATURED) BPF CO-RE (COmpile once - Run Everywhere) support commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
- Introduce composable BPF types commit, commit, commit, commit, commit, commit, commit, commit, commit
New helpers
- (FEATURED) Add bpf_loop helper. One of the complexities of using for loops in bpf programs is that the verifier needs to ensure that in every possibility of the loop logic, the loop will always terminate. As such, there is a limit on how many iterations the loop can do. The bpf_loop helper moves the loop logic into the kernel and can thereby guarantee that the loop will always terminate. The bpf_loop helper simplifies a lot of the complexity the verifier needs to check, as well as removes the constraint on the number of loops able to be run commit, commit, commit, commit
- bpf_find_vma(), to find and inspect VMAs for profiling use cases commit, commit,
- bpf_strncmp(), improve performance, avoid compiler flakiness commit, commit, commit, commit
- bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt() for tracing programs, all inlined by the verifier commit, commit, commit, commit, commit
- Adds unstable conntrack lookup helpers using BPF kfunc support
- Sleepable local storage commit
- Add helpers to access traced function arguments commit, commit, commit, commit, commit
- Support BTF_KIND_TYPE_TAG for btf_type_tag attributes. The main motivation for btf_type_tag is to bring kernel annotations __user, __rcu etc. to btf. With such information available in btf, bpf verifier can detect mis-usages and reject the program. For example, for __user tagged pointer, developers can then use proper helper like bpf_probe_read_kernel() etc. to read the data commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
