Comprehensible changelog of the linux kernel, inspired by [http://wiki.dragonflybsd.org/index.php/DragonFly_Status Dragonfly's status]. Another good places to get more information about the linux kernel are [http://www.kernel-traffic.org Kernel traffic] and [http://www.lwn.net LWN] and their [http://lwn.net/Kernel/ "kernel status" articles], [http://lwn.net/Articles/driver-porting/ driver porting guide] - many of the links here are linking to LWN articles and we wouldn't have been able to restore the 2.5.x-2.6.x changelog without them (you may be insterested in subscribing so Jonathan can keep up the good work ;) ) Before adding things here look at the RULES section at the end of the page!! | #pragma keywords Linux, Kernel, Operating System, Linus Torvalds, Open Source, drivers, filesystems, network, memory management, scheduler, preemption, locking #pragma description Summary of the changes and new features merged in the Linux Kernel during the 2.6.x and 3.x development Changes done in each Linux kernel release. Other places to get news about the Linux kernel are [[http://lwn.net/Kernel/|LWN kernel status]] or the Linux Kernel mailing list (there is a web interface in [[http://www.lkml.org|www.lkml.org]] or [[https://lore.kernel.org/lkml/|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! |

1. Prominent features
1.1. New NTFS file system implementation
The Linux kernel already has a NTFS implementation, but it has severe limitations (like being read-only), which is why Linux users usually use the userspace ntfs-3g implementation. This release incorporates a new and fully functional NTFS implementation contributed by Parangon Software. This implementation supports NTFS file system versions up to 3.1, normal/compressed/sparse files and journal replaying, plus other features that will be added in the future.
1.2. ksmbd, a in-kernel SMB 3 server
ksmbd is a new kernel module which implements the server-side of the SMB 3 protocol. The target is to provide optimized performance, GPLv2 SMB server, and better lease handling (distributed caching). The bigger goal is to add new features more rapidly (e.g. RDMA aka "smbdirect", and recent encryption and signing improvements to the protocol).
This is not meant to replace Samba, which is much broader in scope -tools, security services, LDAP, Active Directory Domain Controller, cross-platform support- but rather be an extension to allow better optimizing for Linux and have better performance and feature integration in some cases.
1.3. Migrate memory pages to persistent memory in lieu of discard
In systems with some DRAM and persistent memory, once DRAM fills up, reclaim will start and some of the DRAM contents will be thrown out. In this release, pages are migrated to persistent memory instead of just being dropped, which improves performance in many benchmarks run in these kind of systems.

1.4. Btrfs support for fs-verity and id mapping
In this release, Btrfs has added support for fs-verity, a generic layer already support by ext4 and F2FS which provides transparent integrity and authenticity protection of read-only files.
It also adds support for id-mapped mounts, which provides the ability to map the user and group id of one mount to another, and some performance improvements.
1.5. DAMON, a data access monitor
DAMON, which stands for Data Access MONitor, is a mechanism to monitor the memory access pattern of specific user-space processes. That is, it can tell you which parts of the memory of a process are being accessed all the time,and which ones are not being used at all. It is lightweight, both in terms of memory usage and CPU usage while analyzing the target process. It is one of the pieces of a project called Data Access-aware Operating System.
DAMON aims to be used by other parts of the kernel that may be merged in the future, but it also can provide information to userspace. You can use it to profile a program and obtain its access heathmap, using the complementary tool damo, find out how your program actually behaves in the real world, and identify the dynamic hotness of your data. You can use this information simply to profile what a process is actually doing, but you can also use it to optimize your program's memory behavior by using mlock() or madvise() with MADV_WILLNEED to lock hot data which you known is going to be used, and/or madvise() with MADV_PAGEOUT to make the system reclaim cold data as soon as possible.
1.6. Introduce process_mrelease(2) system call
In modern systems it's not unusual to have a component monitoring memory conditions of the system and tasked with keeping system memory pressure under control, and killing non-essential processes to free up memory for more important ones. Examples of this are Facebook's OOM killer daemon called oomd and Android's low memory killer daemon called lmkd.
Killing and freeing the resources of a process can be delayed for a long time for various reasons. The new process_mrelease(2) system call allows to release the memory of a dying process from the context of the caller. This way the memory is freed in a more controllable way with CPU affinity and priority of the caller. The workload of freeing the memory will also be charged to the caller.
Recommended LWN article: Hastening process cleanup with process_mrelease()
1.7. Real-time locking progress
The merge of the real-time set of patches continues making progress in every release. In this release, one of the most important pieces, the bulk of the locking code, has been merged. When PREEMPT_RT is enabled, the following locking primitives are substituted by RT-Mutex based variants: mutex, ww_mutex, rw_semaphore, spinlock and rwlock.
The SLUB slab allocator has also been modified to better deal with PREEMPT_RT.
1.8. cgroup support for SCHED_IDLE
This release adds support for putting all the tasks within an entire cgroup under the SCHED_IDLE class of the task scheduler, which means that they will only run if there are not other tasks waiting to run. A key difference with normal tasks set individually to SCHED_IDLE is that tasks within a cgroup set to SCHED_IDLE maintain their relative weights.
1.9. Device Mapper IMA-based remote attestation
This release adds the necessary infrastructure for IMA-based remote attestation. These changes are the basis for deploying DM-based storage in a remote "cloud" that must validate configurations end-users run to maintain trust. It allows supported DM targets' configurations to be measured via IMA. But the policy and enforcement (of which configurations are valid) is managed by something outside the kernel (e.g. Keylime). For more details see the Documentation
1.10. Support for asymmetric scheduling affinity
Some architectures, in particular ARM, have configurations where some CPUs support legacy 32 bits apps, but some CPUs are 64-bit only. This release adds support for scheduling 32 bits tasks exclusively in the CPUs that support legacy 32 bits tasks.
2. Core (various)
(FEATURED) PREEMPT-RT: bulk of the PREEMPT-RT locking infrastructure. In PREEMPT-RT enabled kernels the following locking primitives are substituted by RT-Mutex based variants: mutex, ww_mutex, rw_semaphore, spinlock, rwlock. semaphores are not substituted because they do not provide strict owner semantics. raw_spinlocks are not touched either, as they protect low level operations in the scheduler, timers and hardware access. See the merge commit for more details 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
- Task scheduler
(FEATURED) Add cgroup support for SCHED_IDLE. Treats all the tasks within a cgroup as if they all had been set to the SCHED_IDLE scheduling class commit
(FEATURE) Support for asymmetric scheduling affinity, to support the execution of legacy 32-bit tasks on AArch32 systems that also have 64-bit-only CPUs commit, commit, commit, commit, commit, commit, commit, commit, commit
- io_uring
Add mkdir and [sym]linkat support commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
Instead of opening a file into a process's file table as usual and then registering the fd within io_uring, some users may want to skip the first step and place it directly into io_uring's fixed file table. This patch adds such a capability for IORING_OP_OPENAT and IORING_OP_OPENAT2. See this recommended LWN article. commit, commit, commit, commit

Introduce the concept of the MPOL_PREFERRED_MANY mempolicy. It can be used with either the set_mempolicy(2) or mbind(2) interfaces. Like MPOL_PREFERRED, it allows an application to set a preference for nodes which will fulfil memory allocation requests. Unlike MPOL_PREFERRED, it takes a set of nodes. Like the MPOL_BIND interface, it works over a set of nodes. Unlike MPOL_BIND, it will not cause a SIGSEGV or invoke the OOM killer if those preferred nodes are not available. Recommended LWN article: Multi-preference policies. commit, commit, commit, commit, commit
(FEATURED) Introduce the Data Access MONitor (DAMON). Using this framework, several memory management mechanisms such as reclamation and THP can be optimized to aware real data access patterns.
