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! |

===== 2.6.14 ===== * 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/$PID/smaps: This file will shows how much memory is resident in each mapping. Useful for people who want to perform memory consumption analysis [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e070ad49f31155d872d8e96cab2142840993e3c0 (commit)] * Add /proc/$PID/numa_maps: This file will show on which nodes pages reside [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=6e21c8f145f5052c1c2fb4a4b41bee01c848159b (commit)] * Lock-free file descriptor look-up [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=ab2af1f5005069321c5d130f09cce577b03f43ef (commit)] - [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b835996f628eadb55c5fb222ba46fe9395bf73c7 (commit)] * Four-level page table support for the ppc64 architecture: extends the usable user address range to 44 bits (16T). [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e28f7faf05159f1cfd564596f5e6178edba6bd49 (commit)] * Support hotplug cpu on 32-bit SMP powermacs: When a cpu is off-lined, it is put into sleep mode with interrupts disabled. 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)] * PPTP (Point-to-Point Tunneling Protocol) support: [http://www.ietf.org/rfc/rfc2637.txt RFC 2637]. Used to implement VPN products (notably, Microsoft in all the Windows versions). [http://en.wikipedia.org/wiki/PPTP Wikipedia article] [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=926b50f92a30090da2c1a8675de954c2d9b09732 (commit)] * DCCP: "Datagram Congestion Control Protocol". Datagram protocol (like UDP), but with a congestion control mechanism. [http://lwn.net/Articles/149756/ (LWN article)] Currently a [http://www.icir.org/kohler/dcp/draft-ietf-dccp-spec-11.txt RFC draft] [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=7c657876b63cb1d8a2ec06f8fc6c37bb8412e66c (commit)] * Implement SKB fast cloning: Protocols that make extensive use of SKB cloning, for example TCP, eat at least 2 allocations per packet sent as a result. To cut the kmalloc() count in half, we implement a pre-allocation scheme wherein we allocate 2 sk_buff objects in advance, then use a simple reference count to free up the memory at the correct time [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d179cd12928443f3ec29cfbc3567439644bd0afc (commit)] * Add netlink connector: userspace <-> kernel space easy to use communication module which implements easy to use bidirectional message bus using netlink as its backend [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=7672d0b54411371e0b6a831c1cb2f0ce615de6dc (commit)], also a "async connector mode" [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=acd042bb2de50d4e6fb969281a00cc8b8b71e46d (commit)] * IPV6: Support several new sockopt / ancillary data in Advanced API (RFC3542): IPV6_RECVPKTINFO, IPV6_PKTINFO, IPV6_RECVHOPOPTS, IPV6_HOPOPTS, IPV6_RECVDSTOPTS, IPV6_DSTOPTS, IPV6_RTHDRDSTOPTS, IPV6_RECVRTHDR, IPV6_RTHDR, IPV6_RECVHOPOPTS, IPV6_HOPOPTS, IPV6_{RECV,}TCLASS [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=333fad5364d6b457c8d837f7d05802d2aaf8a961 (commit)] - [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=41a1f8ea4fbfcdc4232f023732584aae2220de31 (commit)] * [http://fuse.sourceforge.net/ FUSE]: Allows to implement a fully functional filesystem in a userspace program [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d8a5ba45457e4a22aa39c939121efd7bb6c76672 (commit)] * [http://v9fs.sourceforge.net/ 9P support]: Linux port of the [http://www.cs.bell-labs.com/sys/doc/9.html Plan9]'s [http://plan9.bell-labs.com/sys/man/5/INDEX.html 9P protocol] [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=93fa58cb831337fdf5d36b3b913441100a484dae (commit)] * [http://relayfs.sourceforge.net/ RelayFS]: Relayfs is just a bunch of per-cpu kernel buffers that can be efficiently written into from kernel code. These buffers are represented as files which can be mmap'ed and directly read from in user space. The purpose of this setup is to provide the simplest possible mechanism allowing potentially large amounts of data to be logged in the kernel and 'relayed' to user space." [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e82894f84dbba130ab46c97748c03647f8204f92 (commit)] * securityfs filesystem [http://lwn.net/Articles/153366/ (LWN article)] [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b67dbf9d4c1987c370fd18fdc4cf9d8aaea604c2 (commit)] * Suspend support for CIFS filesystem [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=ede1327ea4ca8019ec6df24b3e837def091c26b8 (commit)] * Enable atomic inode security labeling on ext3 and ext2: it enables atomic security labeling of newly created inodes by altering the fs code to invoke a new LSM hook to obtain the security attribute to apply to a newly created inode and to set up the incore inode security state during the inode creation transaction. This parallels the existing processing for setting ACLs on newly created inodes [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5e41ff9e0650f327a6c819841fa412da95d57319 (commit)] - [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=10f47e6a1b8b276323b652053945c87a63a5812d (commit)] - [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=ac50960afa31877493add6d941d8402fa879c452 (commit)] * NTFS: Support journals ($Logfile) which have been modified by chkdsk. This means users can boot into Windows after we marked the volume dirty. The Windows boot will run chkdsk and then reboot. The user can then immediately boot into Linux rather than having to do a full Windows boot first before rebooting into Linux [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e7a1033b946f4f2622f2b338ab107f559aad542c (commit)] * SAS transport class [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=c7ebbbce366c02e5657ac6b6059933fe0353b175 (commit)] * Remove ACPI S4 BIOS support [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b01d8684e9e5b04270970c97df856d47668267e3 (commit)] * [http://ipw2100.sourceforge.net/ ipw2100] and [http://ipw2200.sourceforge.net/ ipw2200] wireless drivers (intel centrino) [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2c86c275015c880e810830304a3a4ab94803b38b (commit)] - [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=43f66a6ce8da299344cf1bc2ac2311889cc88555 (commit)] * [http://hostap.epitest.fi/ HostAP]: Adds support to work as "Wireless Access Point" [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=ff1d2767d5a43c85f944e86a45284b721f66196c (commit)] * [http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Linux.Wireless.Extensions.html Wireless extensions] API update to version 19 [http://marc.theaimsgroup.com/?l=linux-netdev&m=112568599006559&w=2 (mail)] [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=6582c164f2b3b6e58d1f13c1c031b19ee691eb14 (commit)] * ISA DMA suspend for x86/x86-64 [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=795312e763569ce4df67e7a0ca726a9901358fa2 (commit)] - [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=7dc24db1757f950f8bd21b7191106d4bf5134be7 (commit)] * PCI: Support PCI PM CAP version 3 [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=3fe9d19f9e86a55679f5f2b38ec0a43a1a510cee (commit)] * Keys: Add possessor permissions to keys. It adds extra permission grants to keys for the possessor of a key in addition to the owner, group and other permissions bits. This makes SUID binaries easier to support without going as far as labelling keys and key targets using the LSM facilities [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=664cceb0093b755739e56572b836a99104ee8a75 (commit)] * Driver for the IBM Hard Drive Active Protection System (HDAPS), an accelerometer found in most modern Thinkpads [http://lwn.net/Articles/155440/ (LWN article)] [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=860e1d6b46bd4cbc67d8d065f0f682143513382f (commit)] * Add Apple USB touchpad driver for the USB touchpad which can be found on post-February 2005 Apple Powerbooks [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=f7214ff4e8248513ec626212b2c1a3ca0b2a0888 (commit)] * Spinlock consolidation [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=fb1c8f93d869b34cacb8b8932e2b83d96a19d720 (commit)] * Largefile support for accounting: The accounting subsystem in the kernel can not correctly handle files larger than 2GB.

When enabled then per-CPU watchdog threads are started, which try to run once per second. If they get delayed for more than 10 seconds then a callback from the timer interrupt detects this condition and prints out a warning message and a stack dump [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=8446f1d391f3d27e6bf9c43d4cbcdac0ca720417 (commit)] * Add kzalloc(): new function, it allows to obtain pre-zeroed memory [http://lwn.net/Articles/147014/ (LWN article)] [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=dd3927105b6f65afb7dac17682172cdfb86d3f00 (commit)] * Add schedule_timeout_{,un}interruptible() [http://lwn.net/Articles/149019 (LWN article)] [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=64ed93a268bc18fa6f72f61420d0e0022c5e38d1 (commit)] |

===== 2.6.13 ===== * Released August 29, 2005 [http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.13 changelog] * Execute-in-place support: Traditionally, programs are loaded from disk to memory to be executed. However, the current wave of embedded devices store programs in a ROM/flash chip. XIP allows the kernel executing programs directly from that ROM, without being copied to RAM (saving RAM space), and bypassing the page cache/io scheduler layers (since they're not needed). [http://lwn.net/Articles/135472/ (LWN article)] [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d763b7a4736e219528f77bf6bc75dd78b1d75c03 (commit)] * i386 CPU hotplug support: provides i386 architecture support for safely unregistering and registering processors during runtime [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=f370513640492641b4046bfd9a6e4714f6ae530d (commit)] * Add /proc/sys/fs/suid_dumpable to provide system-wide control over whether or not set-user-ID and set-group-ID processes produce core dumps. The values accepted are: 0 (default) - traditional behaviour, any process which has changed privilege levels or is execute only will not be dumped. 1 - (debug) - all processes dump core when possible. 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. For security reasons core dumps in this mode will not overwrite one another or other files. This mode is appropriate when adminstrators are attempting to debug problems in a normal environment [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d6e711448137ca3301512cec41a2c2ce852b3d0a (commit)] * x86 now uses the generic PCI bus setup code for assigning unassigned resources * Voluntary preemption patches * build-time configurable clock interrupt frequency: Now HZ defaults to 250 in x86. 1000 is better for "interactivity" (desktops) and 100 is good for performance (servers) and saves some energy in laptops.

With a large request queue (CFQ uses 8192 requests) it is possible to place _all_ memory under I/O at the same time. This means that all memory is pinned and unreclaimable and the VM gets upset and goes oom. 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. Landlock security module
Landlock is a new Linux security module that allows to sandbox applications. The goal of Landlock is to enable to restrict ambient rights (e.g. global filesystem access) for a set of processes. Because Landlock is a stackable LSM, it makes possible to create safe security sandboxes as new security layers in addition to the existing system-wide access-controls. This kind of sandbox is expected to help mitigate the security impact of bugs or unexpected/malicious behaviors in user-space applications. Landlock empowers any process, including unprivileged ones, to securely restrict themselves.
Landlock is inspired by seccomp-bpf but instead of filtering syscalls and their raw arguments, a Landlock rule can restrict the use of kernel objects like file hierarchies, according to the kernel semantic. Landlock also takes inspiration from other OS sandbox mechanisms: XNU Sandbox, FreeBSD Capsicum or OpenBSD Pledge/Unveil.
In this current form, Landlock misses some access-control features. This enables to minimize this patch series and ease review. This series still addresses multiple use cases, especially with the combined use of seccomp-bpf: applications with built-in sandboxing, init systems, security sandbox tools and security-oriented APIs
Recommended LWN article: Sandboxing with the Landlock security module
1.2. Support for Clang Control Flow Integrity
This release builds on last cycle's LTO work, and allows the arm64 kernels to be built with Clang's Control Flow Integrity feature, which is designed to abort the program upon detecting certain forms of undefined behavior that can potentially allow attackers to subvert the program’s control flow. This feature has happily lived in Android kernels for almost 3 years. CFI support for x86 is still under development, but is pretty close.
Recommended LWN article: Control-flow integrity for the kernel
1.3. Support for randomising the stack address offset in each syscall
This release supports randomized stack offsets per syscall to make stack-based attacks harder which rely on the deterministic stack layout. The feature is based on the original idea of PaX's RANDSTACK feature, but uses a significantly different implementation.
The feature is guarded with a static branch which avoids the overhead when disabled. As of this release this is supported for X86 and ARM64.
1.4. Support for concurrent TBL flushing
Currently, local and remote TLB flushes are not performed concurrently, which introduces unnecessary overhead - each INVLPG can take 100s of cycles. This patch-set allows TLB flushes to be run concurrently: first request the remote CPUs to initiate the flush, then run it locally, and finally wait for the remote CPUs to finish their work. In testing this improved sysbench performance measurably by a couple of percentage points, especially if TLB-heavy security mitigations are active.
1.5. Preparatory Apple M1 support
This kernel includes initial support for the Apple M1 platform. The Apple M1 is the processor used it all current generation Apple Macintosh computers. Support for this platform so far is rudimentary, but it boots and can use framebuffer and serial console over a special USB cable.
Support for several essential on-chip devices (USB, PCIe, IOMMU, NVMe) is work in progress but was not ready in time for this release.
A very detailed description of what works is in the commit messages and on the AsahiLinux wiki
1.6. Support for incoming AMD and Intel graphics chips
This release includes initial support for future Intel and AMD chips, such as Intel Alderlake S or AMD Adebaran support
1.7. BPF support for calling kernel functions directly
This release allows bpf programs calling kernel functions (initially to reuse TCP congestion control implementations)
Recommended LWN article: Calling kernel functions from BPF
1.8. A virtio sound driver for improved sound experience on virtualized guests
This release implements a driver part of the virtio sound device specification.
The driver supports PCM playback and capture substreams, jack and channel map controls. A message-based transport is used to write/read PCM frames to/from a device.
As a device part was used OpenSynergy proprietary implementation.
1.9. io_uring support for multi shot mode
Support for multi-shot poll. This allows arming a poll request for a given event mask, and then have it trigger multiple times. The default behavior for io_uring POLL_ADD has been one-shot, where one SQE issued will result in one CQE filled (when the event triggers) and termination of the poll request after that. With multi-shot, one POLL_ADD will generate a CQE every time the event triggers.
1.10. Add misc cgroup
This implements generic support for misc resources which can be controlled by simply counting and limiting the number of resource instances - ie there's X number of these on the system and this cgroup subtree can have upto Y of those.
The first user is the address space IDs used for virtual machine memory encryption and expected future usages are similar - niche hardware features with concrete resource limits and simple usage models
2. Core (various)

- fanotify
- io_uring
(FEATURED) 1) Support for multi-shot poll. This allows arming a poll request for a given event mask, and then have it trigger multiple times, 2) support for POLL_ADD updates. This allows updating the event mask (only) of an existing poll request, both one-shot and multi-shot commit, commit, commit, commit, commit, commit, commit, commit
1) support dynamic managment for registered buffers, including update. Add new IORING_REGISTER* for rsrc register and rsrc update, which are just dispatch files/buffers to right callbacks 3) add rsrc tagging, with tag=0 ignoring CQE posting commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

modules: add CONFIG_MODPROBE_PATH to allow configuring the "/sbin/modprobe" path commit
Adds a special-case when waiting on a pid (via waitpid, waitid, wait4, etc) to avoid doing an O(n) scan of children and tracees, and instead do an O(1) lookup. This can make a substantial performance improvement for applications with a thread that has many children or tracees and frequently needs to wait on them. Tools that use ptrace to intercept syscalls for a large number of processes are likely to fall into this category commit

Introduce prctl(PR_PAC_{SET,GET}_ENABLED_KEYS), which allows the user program to control which PAC keys are enabled in a particular task. The main reason why this is useful is to enable a userspace ABI that uses PAC to sign and authenticate function pointers and other pointers exposed outside of the function, while still allowing binaries conforming to the ABI to interoperate with legacy binaries that do not sign or authenticate pointers. The idea is that a dynamic loader or early startup code would issue this prctl very early after establishing that a process may load legacy binaries, but before executing any PAC instructions commit
