Comprehensible changelog of the linux kernel, inspired by [http://wiki.dragonflybsd.org/index.php/DragonFly_Status Dragonfly's status]. Other places to get news about the linux kernel are [http://www.kernel-traffic.org Kernel traffic], [http://lwn.net/Kernel/ LWN kernel status], [http://lwn.net/Articles/driver-porting/ LWN driver porting guide] and [http://lwn.net/Articles/2.6-kernel-api/ LWN list of API changes in 2.6] - many articles here link to LWN and much of the 2.6.x changelog was restored from them (you may be be interested in subscribing so Jonathan can keep up the good work ;) ) Changes made to the 2.5.x-2.6.0 development series can be found in the Linux25Changes page. 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! |

===== 2.6.15 ===== * '''STILL NOT RELEASED!''' * Page table scalability improvements: Currently, a single page table lock is used to protect all operations on an address space's page tables. This has been detected to cause scalability problems in largue multiprocessor systems ej: 512-cpu SGI altix, specially in heavily multithreaded workloads (threads of a same process share the same address space and hence the same page table lock). With this patch, a separate spinlock per page-table page is used, to guard the page table entries in that page. Splitting the lock is not quite for free: another cacheline access. So for now enable it by config for machines with 4 or more CPUs. While this (and many other scalability changes) may look high-end oriented now, remember that cheap multi-core desktops CPUs are there. [http://lwn.net/Articles/157151/ (LWN article)] [http://marc.theaimsgroup.com/?l=linux-kernel&m=112603203327134&w=2 (benchmark vs SGI's "reduced locking by using atomic page table operations" non-merged approach)] [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=4c21e2f2441dc5fbb957b030333f5a3f2d02dea7 (commit)] * .text page fault SMP scalability optimization: This fixes a case where large systems wouldn't scale well while faulting in the .text. The reason was a useless overwrite of the same pte from all cpu [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=1a44e149084d772a1bcf4cdbdde8a013a8a1cfde (commit)] * Swaptoken tuning: It turns out that the original swap token implementation, by Song Jiang, only enforced the swap token while the task holding the token is handling a page fault, this patch approximates that, like the page fault code does. It has the effect of automatically, and gradually, disabling the enforcement of the swap token when there is little or no paging going on, and "turning up" the intensity of the swap token code the more the task holding the token is thrashing [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=fcdae29aa7a5c79f245110f6680afdc1858d3626 (commit)] * Demand faulting for huge pages [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=4c887265977213985091476be40ab11dfdcb4caf (commit)] * ppc64: support 64k pages. Adds a new CONFIG_PPC_64K_PAGES which, when enabled, changes the kernel base page size to 64K. The resulting kernel still boots on any hardware. On current machines with 4K pages support only, the kernel will maintain 16 "subpages" for each 64K page transparently [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=3c726f8dee6f55e96475574e9f645327e461884c (commit)] * Add generic memory add/remove and supporting functions for memory hotplug [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=3947be1969a9ce455ec30f60ef51efb10e4323d1 (commit)] * "Cooperating processes" for the anticipatory I/O scheduler: Introduce the notion of cooperating processes (those that submit requests close to one another), and use these statistics to make better choices about whether or not to do anticipatory waiting [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=f5b3db0017f8415301f3427b30263186e8478c3f (commit)] * IPv4/IPv6: UFO (UDP Fragmentation Offload) Scatter-gather approach: UFO is a feature wherein the Linux kernel network stack will offload the IP fragmentation functionality of large UDP datagram to hardware. This will reduce the overhead of stack in fragmenting the large UDP datagram to MTU sized packets [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e89e9cf539a28df7d0eb1d0a545368e9920b34ac (commit)] * Add the infrastructure to support hotplug CPU on ARM [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a054a811597a17ffbe92bc4db04a4dc2f1b1ea55 (commit)] * x86 hot plug CPU support of physical add of new processors (hotplug add/remove of already existing CPUs was already supported) [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9f40a72a7e819789f66910c8cd60aab005cdb413 (commit)] * Add LSM hooks for key management facilities (see link) [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=29db9190634067c5a328ee5fcc2890251b836b4b (commit)] * RCU torture-testing kernel module: This adds a tristate CONFIG_RCU_TORTURE_TEST, which enables an intense torture test of the RCU infratructure. This is needed for testing due to the continued changes to the RCU infrastructure [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a241ec65aeac3d69a08a7b153cccbdb7ea35063f (commit)] * Support for shared HPET interrupts: The driver previously acknowledged interrupts for both edge and level interrupts, but didn't actually allow a shared interrupt in the latter case [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0d29086177aaa1e7d14e6ebb7fc067b3ca6d5c11 (commit)] * Driver Core: add the ability for class_device structures to be nested: Allows struct class_device to be nested, so that another struct class_device can be the parent of a new one, instead of only having the struct class be the parent [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=51d172d5f3a193e4b8f76179b2e55d7a36b94117 (commit)] * Add vmalloc_node(size, node) (allocate necessary memory on the specified node) and get_vm_area_node(size, flags, node) [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=930fc45a49ddebe7555cc5c837d82b9c27e65ff4 (commit)] * Generic dispatch queue: Implements generic dispatch queue which can replace all dispatch queues implemented by each iosched [http://marc.theaimsgroup.com/?l=linux-kernel&m=112238633622498&w=2 (mailing list)] [http://lwn.net/Articles/157208/ (LWN article)] [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=8922e16cf6269e668123acb1ae1fdc62b7a3a4fc (commit)] * Reimplement elevator online switching code [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=cb98fc8bb9c141009e2bda99c0db39d387e142cf (commit)] * Process Events Connector: It reports fork, exec, id change, and exit events for all processes to userspace.

===== 2.6.14 ===== * Released October 27, 2005 [http://kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.14 changelog] * Numa-aware slab allocator: It creates slabs on multiple nodes and manages slabs in such a way that locality of allocations is optimized. Each node has its own list of partial, free and full slabs. All object allocations for a node occur from node specific slab lists [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e498be7dafd72fd68848c1eef1575aa7c5d658df (commit - benchmarks)] * Lazy page table copies in fork() for VMAs without anonymous pages (the ones with anonymous pages are still copied): Defer copying of ptes until fault time when it is possible to reconstruct the pte from backing store, speeding up fork() greatly specially for processes using lots of shared memory [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d992895ba2b27cf5adf1ba0ad6d27662adc54c5e (commit)] * Add /proc/$PID/smaps: This file will shows how much memory is resident in each mapping.

It can be on-lined again by asserting its soft-reset pin, which is connected to a GPIO pin [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=31139971b3dc9fbb2e8a8572fb81e6e8470f363a (commit)] * Add TASK_NONINTERACTIVE task state bit to the cpu scheduler: It can be used by blocking points to mark the task's wait as "non-interactive". This does not mean the task will be considered a CPU-hog - the wait will simply not have an effect on the waiting task's priority - positive or negative alike [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d79fc0fc6645b0cf5cd980da76942ca6d6300fa4 (commit)] * [http://www.ietf.org/rfc/rfc2637.txt PPTP] (Point-to-Point Tunneling Protocol) conntrack support and NAT helper added to allow proper management of multiple NAT'd PPTP connections.

The core dump is owned by the current user and no security is applied. This is intended for system debugging situations only. Ptrace is unchecked. 2 - (suidsafe) - any binary which normally would not be dumped is dumped readable by root only. This allows the end user to remove such a dump but not access it directly.

With a large request queue (CFQ uses 8192 requests) it is possible to place _all_ memory under I/O at the same time.

This patch limits the amount of memory which is under pageout writeout to be a little more than the amount of memory at which balance_dirty_pages() callers will synchronously throttle.

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
Recommended LWN article: Defending mounted filesystems from the root user
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).

(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
