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 6.7 was released on Sunday, 7 January 2024.

Summary: This release includes bcachefs, a new filesystem that implements the same kind of modern features you can expect from Btrfs and ZFS; it also includes the first pieces of the future futex2 system call; support in Btrfs for a RAID stripe tree that will be used to implement some future new features; suport in BPF for exceptions and other features; support for io_uring features such as multishot reads, cancelable uring_cmd, support for {s,g}etsockopt commands and other things; support for TCP Authentication Option; and allow disabling x86 32 bit emulation. As always, there are many other features, new drivers, improvements and fixes.

1. Prominent features

1.1. Bcachefs, a new modern file system

This release includes bcachefs, a new modern file systems that aims to provide the kind of modern features that you can find in ZFS/Btrfs (copy on write model, full checksumming, multivolume management, snapshots, compression, encryption, etc). For more details see https://bcachefs.org/

1.2. First pieces of futex2

The futex(2) ("fast userspace mutex") system call has a number of limitations. This system call has incorporated too much funcionality over the years; in order to avoid the dreaded "multiplexed syscall" pattern (one single system call doing many things), it has been decided to incorporate multiple calls (futex_wait, futex_wake, futex_requeue). This release adds the first pieces of these new system calls - the complete feature set will be added in future releases.

Recommended LWN article: A new futex API

1.3. Btrfs stripe tree and other improvements

This release introduces the RAID stripe tree, a new tree for logical file extent mapping where the physical mapping may not match on multiple devices. This is now used in zoned mode to implement RAID0/RAID1* profiles, but can be used in non-zoned mode as well. The support for RAID56 is in development and will eventually fix the problems with the current implementation.

This release also includes support for temporary filesystem ID and simple quota accounting.

1.4. BPF exceptions and other features

As usual, BPF incorporates a few new features, one of them being BPF exceptions, which allow a BPF program testing conditions that are always true at runtime but which the verifier has no visibility into, and then quitting and unwinding safely.

Recommended LWN article: Exceptions in BPF

1.5. io_uring improvements

This release includes as number of improvements to the io_uring interface

Multishot reads
Cancelable uring_cmd
Initial support for {s,g}etsockopt commands
An async version of waitid(2)
Add support for using futexes through io_uring - first futex wake and wait, and then the vectored variant of waiting, futex waitv

1.6. Support for TCP Authentication Option

This release adds support for TCP Authentication Option (RFC5925). The TCP Authentication Option (TCP-AO) provides a TCP extension aimed at verifying segments between trusted peers. It adds a new TCP header option with a Message Authentication Code (MAC). MACs are produced from the content of a TCP segment using a hashing function with a password known to both peers. The intent of TCP-AO is to deprecate TCP-MD5 providing better security, key rotation and support for variety of hashing algorithms.

Recommended read: Documentation, RFC 5925

1.7. Allow disabling x86 32 bit emulation

x86-64 processors support running 32 bit software. In order to allow running that software under Linux, the kernel provides 32-bit syscalls. Some distributions would like to disable this layer in order to reduce their attack surface as much as possible but at the same time they'd want to retain flexibility to cater to a variety of legacy software. In order to suppor this case, this release allows to enable/disable this feature at boot time.

2. Core

Add the futex2 family of system calls (futex_wait, futex_wake, futex_requeue), which are an attempt to get away from the multiplex syscall and adds a little room for extensions, while lifting some limitations commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
console: introduce the new non-BKL consoles (nbcon) base commit, commit, commit, commit, commit, commit, commit, commit

This can be used to generate a record of what memory is being dirtied by DMA activities during a VM migration process. A VMM like qemu will combine the IOMMU dirty bits with the CPU's dirty log to determine what memory to transfer commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

  * '''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)]

  * "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)]

  * 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)]

-===== 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)]
  * [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. PPTP, a Microsoft-designed protocol, is used in many places to provide VPN access due to the native support in Microsoft Windows. [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)]

  * 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)]

===== 2.6.12 =====
  * Released June 17, 2005 [http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.12 changelog]
  * Pageout throttling: With silly pageout testcases it is possible to place huge amounts of memory under I/O.  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. This means that heavy pageout activity can starve heavy writeback activity completely, but heavy writeback activity will not cause starvation of pageout [http://kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=3799f8fcebf940f21c69e80ded882245a8bc67a7 (commit)]

  * RLIMIT_MEMLOCK semantics change: In Linux kernels before 2.6.9, only privileged processes (CAP_IPC_LOCK) could lock memory, and the RLIMIT_MEMLOCK soft resource limit placed an upper limit on the number of bytes that a privileged process can lock.  Since kernel 2.6.9: no limits are placed on the amount of memory that a privileged process can lock; and an unprivileged process is now able to lock memory up to the soft limit defined by RLIMIT_MEMLOC [http://kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=adaeb8014406050050cf09416d1b0e3c23838fdb (commit)]

  * Support for POSIX's waitid() Also, now linux now supports the POSIX specification that SIGCHLD is sent to the parent when one of its children resumes as a consequence of receiving a SIGCONT signal. Also, WCONTINUED flag is added to waitpid() and waitid() [http://kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=8e81583bfd488bb0b10aa799f7ec5f7b4a79fe73 (commit)].

  * x86 PAE swapspace expansion. PAE is artificially limited in terms of swapspace to the same bitsplit as ordinary i386, a 5/24 split (32 swapfiles, 64GB max swapfile size), when a 5/27 split (32 swapfiles, 512GB max swapfile size) is feasible. This patch transparently removes that limitation by using more of the space available in PAE's wider ptes for swap ptes [http://kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=7c1c60d14d175c41c5db03f20f44c80c4d683e52 (commit)]

  * VFS shrinkage tuning: This adds /proc/sys/vm/vfs_cache_pressure, which tunes the vfs cache versus pagecache scanning pressure. At vfs_cache_pressure=0 we don't shrink dcache and icache at all, at vfs_cache_pressure=100 there is no change in behaviour, at vfs_cache_pressure > 100 we reclaim dentries and inodes harder [http://kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=95afb3658a8217ff2c262e202601340323ef2803 (commit)]

  * Add O_NOATIME open flag support (GNU extension): If this bit is set, read will not update the access time of the file. It is useful if you want to do something with the file atime (for instance, moving files that have not been accessed in a while to somewhere else, or something like Debian's popularity-contest) but you also want to read all files periodically (for instance, tripwire or debsums) [http://kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=037c5577398a9d87f0b9f8d68cbf17324b5b05fe (commit)]
  * MNT_EXPIRE for umount(): Intrinsic automount and mountpoint degradation support. This adds support for a filesystem (such as kAFS) to perform automounting intrinsically without the need for a userspace daemon. It also adds support for such mountpoints to be degraded at the filesystem's behest until they've been untouched long enough that they'll be removed [http://kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=92b2af55e9bd44724700c8eef889c7b368df6c94 (commit)]
