==== 2.6.16 ==== * /!\ '''STILL NOT RELEASED!''' /!\ * '''Kernel Core changes''' * '''Architecture-specific''' * '''Filesystems''' * '''Networking''' * '''Drivers''' ==== 2.6.15 ==== * Released 3 January, 2006 (fifteen years since Linus bought the machine that got Linux started) [http://kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.15 changelog] * '''Kernel Core changes''' * VFS changes: The "shared subtree" patches have been merged. Shared subtree semantics provide the building blocks for features like per-user-namespace, "files as directories" and versioned filesystems [http://lwn.net/Articles/159077/ Detailed LWN article], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/sharedsubtree.txt Documentation], original [http://marc.theaimsgroup.com/?l=linux-fsdevel&m=110565591630267&w=2 Alexander Viro's RFC]. Patches: * beginning of the shared-subtree proper: A private mount does not forward or receive propagation. This patch provides user the ability to convert any mount to private [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=07b20889e3052c7e77d6a6a54e7e83446eb1ba8 (commit)] * introduce shared mounts: This creates shared mounts. A shared mount when bind-mounted to some mountpoint, propagates mount/umount events to each other. All the shared mounts that propagate events to each other belong to the same peer-group [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=03e06e68ff76294e53ffa898cb844d2a997b043e (commit)] * introduce slave mounts: A slave mount always has a master mount from which it receives mount/umount events. Unlike shared mount the event propagation does not flow from the slave mount to the master [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a58b0eb8e64b78d9315a5491955e78b1391d42e5 (commit)] * handling of shared mounts: This makes bind, rbind, move, clone namespace and umount operations aware of the semantics of slave mount [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5afe00221389998a25d611dc7941c06580c29eb6 (commit)] * shared mount handling: bind and rbind: Implement handling of MS_BIND in presence of shared mounts [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b90fa9ae8f51f098ee480bbaabd6867992e9fc58 (commit)] * unbindable mounts: An unbindable mount does not forward or receive propagation. Bind semantics: It is invalid to bind mount an unbindable mount. Move semantics: It is invalid to move an unbindable mount under shared mount. Clone-namespace semantics: If a mount is unbindable in the parent namespace, the corresponding cloned mount in the child namespace becomes unbindable too. Note: there is subtle difference, unbindable mounts cannot be bind mounted but can be cloned during clone-namespace [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9676f0c6389b62bd6b24d77d4b3abdbcfa32d0f2 (commit)] * shared mount handling: move: Implement handling of mount --move in presence of shared mounts [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2144440327fa01b2f3f65e355120a78211685702 (commit)] * shared mount handling: umount: An unmount of a mount creates a umount event on the parent. If the parent is a shared mount, it gets propagated to all mounts in the peer group [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a05964f3917c7c55368c229d7985f8e7c9977e97 (commit)] * 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 large 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)] * Reorder struct files_struct: The file_lock spinlock sits close to mostly read fields of 'struct files_struct'. In SMP (and NUMA) environments, each time a thread wants to open or close a file, it has to acquire the spinlock, thus invalidating the cache line containing this spinlock on other CPUS. This patch microoptimizes this by moving the spinlock to another cache line, so that concurrent threads can share the cache line containing 'count' and 'fdt' fields. It's worth up to 9% on a microbenchmark using a 2-physical-4-virtual CPU [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=95e861db3eaba7bc99f8605db70103ec3d078203 (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)] * 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)] * 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. Applications that may find these events useful include accounting/auditing (e.g. ELSA), system activity monitoring (e.g. top), security, and resource management (e.g. CKRM) [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9f46080c41d5f3f7c00b4e169ba4b0b2865258bf (commit)] * RCU torture-testing kernel module: This adds a tristate CONFIG_RCU_TORTURE_TEST, which enables an intense torture test of the RCU infrastructure. 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)] * 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)] and add uevent sysfs attribute to re-emit device hotplug events [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a7fd67062efc5b0fc9a61368c607fa92d1d57f9e (commit)]. Also, introduce struct platform_driver (allows the platform device driver methods to be passed a platform_device structure instead of instead of a plain device structure, and therefore requiring casting in every platform driver) [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=00d3dcdd96646be6059cc21f2efa94c4edc1eda5 (commit)]. Due to some of those changes, only udev versions 071 or higher will be able to run in 2.6.15. * Implement nice support across physical cpus on SMP to obtain good distribution of tasks of different nice values [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b910472dd3b7c1d51af9a594a759f642520c33e1 (commit)] * make /proc/mounts pollable [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5addc5dd8836aa061f6efc4a0d9ba6323726297a (commit)] * SELinux: Enables files created on a MLS-enabled SELinux system to be accessible on a non-MLS SELinux system [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e517a0cd859ae0c4d9451107113fc2b076456f8f (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)] * 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)] * SHM_NORESERVE flags for shmget(): Similar to MAP_NORESERVE for shared memory segments. This is mainly to avoid abuse of OVERCOMMIT_ALWAYS and this flag is ignored for OVERCOMMIT_NEVER [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=bf8f972d3a1daf969cf44f64cc36d53bfd76441f (commit)] * Add vm_insert_page() to use for drivers, which need to insert individual pages into a user vma without the hassles of PAGE_RESERVED [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a145dd411eb28c83ee4bb68b66f62c326c0f764e (commit)] * '''Architecture-specific''' * x86-64: Add a new 4GB GFP_DMA32 zone between the GFP_DMA and GFP_NORMAL zones. Full details in the commit link [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a2f1b424900715ed9d1699c3bb88a434a2b42bc0 (commit)] * i386: generic cmpxchg. Makes cmpxchg generally available on the i386 platform, providing emulation of cmpxchg suitable for uniprocessor if built and run on 386 - necessary for multithreaded environments with libraries using cmpxchg [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=53e86b91b7ae66d4c2757195cbd42e00d9199cf2 (commit)] * x86-64: Support for AMD specific MCE Threshold. DRAM Errors Threshold Register realized under AMD K8 Rev F, this register is used to count correctable and uncorrectable ECC errors that occur during DRAM read operations. The user may interface through sysfs files in order to change the threshold configuration [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=89b831ef8bf5cfbb357dbc0a2e07700d7f20eec5 (commit)] * x86-64: Support ULI/ALI 1689 bridge [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=870b7681cd3f867c1ffc8d7fbe9b22216e73a536 (commit)] * x86 hot plug CPU support of physical add of new processors (hotplug disable/enable 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)] * 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)] * 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)] * ppc64: CPU freq support using 970FX powertune facility for iMac G5 and SMU based single CPU desktop [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=4350147a816b9c5b40fa59e4fa23f17490630b79 (commit)] * ppc64: Adds the ability to the SMU driver to recover missing calibration partitions from the SMU chip itself.

You can write(2) to a file even beyond the end of the existing file. Resident non-resident files and are supported. Sparse files can also be written and holes will be filed appropriately. truncate(2), ftruncate(2) and open(2) with O_TRUNC flag also works. There're some limitations with heavily fragmented files which you won't be allowed to change.

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.
Recommended read: Design document
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.

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
Expose boot-loader kernel command-line arguments commit, commit, commit
file: convert file cache to rely on SLAB_TYPESAFE_BY_RCU which allows us to get rid of call_rcu() based freeing for files commit
fanotify: Support more filesystems with FAN_REPORT_FID commit, commit, commit, commit
- Task scheduler
Give CPUs within the same cluster a try before scanning the whole LLC to benefit those tasks communicating with each other commit, commit, commit
Ratelimit updates to tg->load_avg commit
numa: Complete scanning of partial and inactive VMAs commit, commit, commit, commit, commit
Remove SIS_PROP, SIS_UTIL seems to work well commit
Disable IBRS when CPU is offline to improve single-threaded performance commit
prctl: Allow MDWE without inheritance commit, commit, commit, commit, commit, commit

Introduce 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.

configfs-tsm: Attestation Report ABI. The current momentum has been to invent new ioctl-ABI per TSM per function which at best is an abdication of the kernel's responsibility to make common infrastructure concepts share common ABI.
