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.

Linux 6.8 was released on Sunday, 10 March 2024.

Summary: This release includes two new system calls for easier mount management; support for multi-size transparent huge pages in anonymous page faults; data type profiling support in perf which allows to correlate perf events with DWARF information; task scheduler support for better realtime scheduling; an option to forbid users from writing to partitions that are being used by file systems; new system calls to deal with multiple stacked LSMs; and a new driver for Intel Xe graphics. As always, there are many other features, new drivers, improvements and fixes.

1. Prominent features

1.1. Deadline servers for better realtime scheduling

Processes placed in the realtime scheduling class can starve other processes in classes with lower priority, which can cause problems. The Linux kernel uses a technique called "RT throttling" to avoid problems, but it not as performant as it could, so in this release the Linux kernel will use the so called "deadline servers", which replaces and improve that.

1.2. Multi-size transparent huge pages for anonymous memory

Anonymous page faults (eg. faults for memory allocated by malloc) are usually done with a 4KB size. Work on [[https://kernelnewbies.org/Linux_5.16#Memory_folios_infrastructure_for_a_faster_memory_management|"folios" ]] now allows to allocate more than 4KB during a single page fault. This release adds support for it, and it also adds support for TBL compresion techniques allowed in modern hardware that allow to map physically contiguous chunks of memory. By default, the existing behaviour (and performance) is maintained. The user must explicitly enable multi-size THP to see the performance benefit.

1.3. Two new syscalls for better mount management: listmount() and statmount()

Modern Linux systems can contain many mounts. Listing them and gathering information about their properties is not as easy as it should. Two new syscalls, listmount(2) and statmount(2) have been added to faciliate this effort.

Recommended LWN article: listmount() and statmount()

1.4. Data type profiling with perf

The perf tool in this release adds a feature called data type profiling , which allows to associate PMU samples to data types they refer using DWARF debug information. It depends on quality of PMU events and compiler for producing DWARF info, but it doesn't require any changes in the target program.

This allows the creation of tools that can do things such as pahole-style structure reordering or packing, but doing so with information about access patterns gathered from perf.

1.5. Forbid users from writing to partitions used by filesystems

This release adds a configuration option that forbids wriing to block devices that are being used by a mounted filesystem

1.6. New system calls to deal with multiple stacked LSMs

The Linux kernel added support for stacking security modules in Linux 5.1. LSM-aware applications, however, need some interfaces to get more information about the current LSM configuration. This release adds three new syscalls lsm_list_modules(), lsm_get_self_attr(), and lsm_set_self_attr(). These syscalls were designed to support multiple, simultaneaous (stacked) LSMs from the start as opposed to the current /proc based solutions which were created at a time when only one LSM was allowed to be active at a given time.

1.7. Driver for new Intel Xe graphics

This release adds a new driver, Xe, for Intel GPUs that supports both integrated and discrete platforms starting with Tiger Lake (first Intel Xe Architecture)

2. Core (various)

(FEAURED) Add two mount querying syscalls: listmount(2) (which adds a way to query the children of a particular mount) and statmount(2) (which adds a way to query attributes of a single mount). They are more flexible than having to parse the complete /proc/self/mountinfo commit, commit, commit, commit, commit, commit, commit, commit
dmesg: CAP_SYSLOG was separated from CAP_SYS_ADMIN and introduced in Linux 2.6.37. For a long time, certain syslog actions required CAP_SYS_ADMIN or CAP_SYSLOG. Remove CAP_SYS_ADMIN for more fine-grained control commit

9. Security

(FEATURED) LSM: Three new syscalls: lsm_list_modules(), lsm_get_self_attr(), and lsm_set_self_attr(). The first syscall simply lists the LSMs enabled, while the second and third get and set the current process' LSM attributes. Yes, these syscalls may provide similar functionality to what can be found under /proc or /sys, and considerable time has been spent trying to extend them, but these new syscalls were designed to support multiple, simultaneaous (stacked) LSMs from the start as opposed to the current /proc based solutions which were created at a time when only one LSM was allowed to be active at a given time commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
