| 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 ===== * '''STILL NOT RELEASED!!''' * Numa-aware slab allocator [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."

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.

| ===== 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.

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. Improved kernel memory allocation performance with slub sheaves
Operating system kernels often need to allocate small amounts of memory, there is a mechanism called slab that does that. The Linux implementation is called Slub.
This release adds a feature called "sheaves", which could be described in essence as a per-CPU cache, so that allocations can be done locally most of the time. Previously, synchronization primitives were required that involved other CPUs. As a result, there is a performance improvement in both the allocation and freeing paths. It also adds support for kfree_rcu() batching and recycling.

1.2. A device mapper target for persistent cache
This release adds a pcache target which provides a mechanism to use persistent memory (e.g., CXL persistent memory, DAX-enabled devices) as a high-performance cache layer in front of traditional block devices such as SSDs or HDDs.
Documentation: dm-pcache — Persistent Cache
1.3. Process Namespaces as file handlers
The Linux kernel has supported "pidfds" (using file descriptors as stable handles to a process) since Linux 5.1. This has proven to be very useful.
In this release it is possible to encode and decode namespace file handles using the common name_to_handle_at() and open_by_handle_at() APIs. It has the same advantage as pidfds. It's possible to reliably and for the lifetime of the system refer to a namespace without pinning any resources and to compare them.

1.4. Support for Accurate Explicit Congestion Notification in TCP
This release includes initial support for Accurate Explicit Congestion Notification (currently a draft, which will be RFC 9768).
Explicit Congestion Notification (ECN) is a mechanism where network nodes can mark IP packets, instead of dropping them, to indicate incipient congestion to the endpoints. Receivers with an ECN-capable transport protocol feed back this information to the sender. ECN was originally specified for TCP in such a way that only one feedback signal can be transmitted per Round-Trip Time (RTT). Recent new TCP mechanisms need more Accurate ECN feedback information whenever more than one marking is received in one RTT.
This release adds support for a scheme that provides more than one feedback signal per RTT in the TCP header. It allows feeding back the number of Congestion Experienced marks accurately to the sender. Congestion control algorithms can take advantage of the accurate ECN information to fine-tune their congestion response to avoid drastic rate reduction when only mild congestion is encountered.
1.5. Add support for PSP encryption of TCP connections
PSP is a protocol out of Google. It shares some similarities with IPsec and TLS, but offers superior HW offloads capabilities. The protocol can work in multiple modes including tunneling.
Documentation: PSP Security Protocol
PSP paper: PSP_Arch_Spec.pdf
1.6. Better swapping performance
This release improves the swap performance in two different ways:
- First phase of the bigger series implementing basic infrastructures for the "Swap Table" idea proposed at the LSF/MM/BPF. This phase I introduces the swap table infrastructure and uses it as the swap cache backend. By doing so, we have up to ~5-20% performance gain in throughput, RPS or build time for benchmark and workload tests. Documentation: Swap Table. Recommended LWN article: A new swap abstraction layer for the kernel - Improve performance of large page allocation performance and reduce the failure rate and fragmentation. In a build kernel test with make -j96 and 10G ZRAM with 64kB mTHP enabled, the newer version shows better performance and a lower failure rate: system time is cut in half, and the failure rate drops to zero. Larger allocations in a hybrid workload also show a major improvement.
1.7. UDP receive performance improvements
This releases optimizes the UDP stack on the receive side, especially when under one or several UDP sockets are receiving a DDOS attack, by reducing contention, revisiting the binary layout of the involved data structs and implementing NUMA-aware locking. This improves UDP RX performance by an additional 50%, even more under extreme conditions.
1.8. BPF signed programs
This release implements the ability to load BPF programs that are cryptographically signed. Future development is in implementing security policies and paving the way for allowing unprivileged users to load vetted BPF programs.
Recommended LWN article: Possible paths for signing BPF programs
1.9. More scalable NFS servers by removing caching
This release includes a prototype that disables I/O caching in the NFS server. This enables scaling the NFS server in both directions: NFS service can be supported on systems with small memory footprints, such as low-cost cloud instances; and also large NFS workloads will be less likely to force the eviction of server-local activity, helping it avoid thrashing.
1.10. Introduction of memdesc_flags_t, for a future leaner struct page
Linux uses the struct page to manage RAM memory. This structure is a bit bloated, and efforts are being done to improve it. At some point struct page will be separated from struct slab and struct folio. This is a step towards that by introducing a type for the 'flags' word of all three structures. This release introduces memdesc_flags_t and starts using it.
