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.

You can discuss the latest Linux kernel changes on the New Linux Kernel Features Forum.
Linux 6.17 was released on Sunday, 28 September 2025.
Summary: This release includes an easier way to select CPU bug mitigations, based on chosen attack vectors that will be updated as new CPU bugs are discovered. It also adds new file_getattr/file_setattr system calls for setting extended file attributes with openat(2) semantics, better and more secure core dumping, initial priority inheritance support for solving priority inversion, unconditionally compilation of the task scheduler with SMP support, per NUMA node proactive reclaim for better control of memory reclaim on NUMA systems, a new fallocate(2) flag for more efficient writing of zeroes, and support for linear temporal logic monitors in the runtime verification. As always, there are many other features, new drivers, improvements and fixes.

1. Prominent features
1.1. Easier CPU bug mitigation selection
This release proposes new kernel command line options to make it easier to control which CPU mitigations are applied. These options select relevant mitigations based on chosen attack vectors. Administrators are encouraged to consider which attack vectors are relevant and disable all others in order to recoup system performance. When new relevant CPU vulnerabilities are found, they will be added to these attack vector controls so administrators will likely not need to reconfigure their command line parameters as mitigations will continue to be correctly applied based on the chosen attack vector controls.

1.2. New file_getattr/file_setattr system calls
This release include two new syscalls file_getattr() and file_setattr(), which can be used to set extended file attributes. They take dir fd in conjunction with a pathname argument. The syscall then operates on inode opened according to openat(2) semantics. This is an alternative to FS_IOC_FSGETXATTR/FS_IOC_FSSETXATTRioctl with a difference that file don't need to be open as file can be referenced with a path instead of fd. By having this one can manipulated filesystem inode attributes not only on regular files but also on special ones.
1.3. Better and more secure core dumping
This release continues building on top of features incorporated in past release, and extends the coredump socket to allow the coredump server to tell the kernel how to process individual coredumps, which allows for fine-grained coredump management. This scheme allows for safer core dumping.

1.4. Initial priority inheritance support for solving priority inversion
A common way to solve the problem of https://en.wikipedia.org/wiki/Priority_inversion is priority inheritance: a lower priority task will inherit the priority of a higher-priority task when they are competing for a shared resourced (lock). This release adds an initial version of proxy execution: a mechanism for mutex-owning tasks to inherit the scheduling context of higher priority waiters. Currently limited to a single runqueue and conditional on CONFIG_EXPERT, and other limitations.

1.5. Unconditionally compile task scheduler with SMP support
This is not a feature, but rather an interesting change that shows where the world is heading. In this release, the task scheduler has removed code that is specific for single-processor systems, leaving only the multiprocessor code available. This does not mean that you cannot run Linux on a single-processor system. Rather, it means that the code paths that were specific for those systems have been removed, and from now on, the multiprocessor-specific code will handle these systems, by detecting only one processor. The consequence of this change is simplification and removal of many lines of code and #ifdef code in the task scheduler.

1.6. Per NUMA node proactive reclaim, for better control of memory reclaim on NUMA systems
This release adds support for allowing proactive reclaim in general on a NUMA system. per-node interface extends support for beyond a memcg-specific interface, respecting the current semantics of memory.reclaim: respecting aging LRU and not supporting artificially triggering eviction on nodes belonging to non-bottom tiers. This allows userspace to do echo 512M swappiness=10 > /sys/devices/system/node/nodeX/reclaim
1.7. Introduce a new fallocate(2) flag, for more efficient writing of zeroes
Currently, userspace can use fallocate(2) to quickly create a pre-allocated file. However, on most filesystems, such as ext4 and XFS, this creates pre-allocation blocks in an unwritten state, and the FALLOC_FL_ZERO_RANGE flag also behaves similarly. The extent state must be converted to a written state when the user writes data into this range later, which can trigger numerous metadata changes and consequent journal I/O. We need a method to create a pre-allocated file with written extents that can be used for pure overwriting. At the moment, the only method available is to create an empty file and write zero data into it, which is slow and consumes a considerable amount of disk bandwidth
Fortunately, with the development and more and more widely used of flash-based storage devices, we can efficiently write zeros to SSDs using the unmap write zeroes command if the devices do not write physical zeroes to the media. For example, if SCSI SSDs support the UMMAP bit or NVMe SSDs support the DEAC bit, the write zeroes command does not write actual data to the device, instead, NVMe converts the zeroed range to a deallocated state, which works fast and consumes almost no disk write bandwidth. This release introduce a new flag FALLOC_FL_WRITE_ZEROES, into fallocate(2) to use it.
1.8. Runtime Verification: Support for Linear temporal logic monitors
(See this documentation for more details on what Runtime Verification is)
Real-time applications may have design flaws causing them to have unexpected latency. For example, the applications may raise page faults, or may be blocked trying to take a mutex without priority inheritance.
However, while attempting to implement DA monitors for these real-time rules, deterministic automaton is found to be inappropriate as the specification language. The automaton is complicated, hard to understand, and error-prone. For these cases, linear temporal logic is found to be more suitable, concise and intuitive. This release adds support for expressing
