#pragma section-numbers on #pragma keywords Linux, kernel, operating system, changes, changelog, file system, Linus Torvalds, open source, device drivers #pragma description Summary of the changes and new features merged in the Linux kernel during the 4.0 development cycle Linux 4.0 [https://lkml.org/lkml/2015/4/12/178 has been released] on Sun, 12 Apr 2015. Summary: This release adds support for live patching the kernel code, aimed primarily at fixing security updates without rebooting; DAX, a way to avoid using the kernel cache when filesystems run on systems with persistent memory storage; kasan, a dynamic memory error detector that allows to find use-after-free and out-of-bounds bugs; lazytime, an alternative to relatime, which causes access, modified and changed time updates to only be made in the cache and written to the disk opportunistically; allow overlayfs to have multiple lower layers, support of Parallel NFS server architecture; and dm-crypt CPU scalability improvements. There are also new drivers and many other small improvements. [[TableOfContents()]] = Prominent features = == Arbitrary version change == This release increases the version to 4.0. This switch from 3.x to 4.0 version numbers is, however, entirely meaningless and it should not be associated to any important changes in the kernel. This release could have been 3.20, but Linus Torvalds just got tired of the old number, [https://plus.google.com/+LinusTorvalds/posts/jmtzzLiiejc made a poll], and changed it. Yes, it is frivolous. The less you think about it, the better. == Live patching == This release introduces "livepatch", a feature for live patching the kernel code, aimed primarily at systems who want to get security updates without needing to reboot. This feature has been born as result of merging kgraft and kpatch, two attempts by SuSE and Red Hat that where started to replace the now propietary ksplice. It's relatively simple and minimalistic, as it's making use of existing kernel infrastructure (namely ftrace) as much as possible. It's also self-contained and it doesn't hook itself in any other kernel subsystems. In this release livepatch is not feature complete, yet it provides a basic infrastructure for function "live patching" (i.e. code redirection), including API for kernel modules containing the actual patches, and API/ABI for userspace to be able to operate on the patches (look up what patches are applied, enable/disable them, etc). Most CVEs should be safe to apply this way. Only the x86 architecture is supported in this release, others will follow. For more details see the [https://git.kernel.org/linus/1d9c5d79e6e4385aea6f69c23ba543717434ed70 merge commit] Sample live patching module: [https://git.kernel.org/linus/13d1cf7e702596e0cd8ec62afa6bd49c431f2d0c commit] Code [https://git.kernel.org/linus/b700e7f03df5d92f85fa5247fe1f557528d3363d commit] == DAX - Direct Access, for persistent memory storage == Before being read by programs, files are usually first copied from the disk to the kernel caches, kept in RAM. But the possible advent of persistent non-volatile memory that would be also be used as disk changes radically the way the kernel deals with this process: the kernel cache would become unnecesary overhead. Linux has had, in fact, support for this kind of setups [http://kernelnewbies.org/Linux_2_6_13 since 2.6.13]. But the code wasn't maintaned and only supported ext2. In this release, Linux adds DAX (Direct Access, the X is for eXciting). DAX removes the extra copy incurred by the buffer by performing reads and writes directly to the persistent-memory storage device. For file mappings, the storage device is mapped directly into userspace. Support for ext4 has been added.

It provides fast and comprehensive solution for finding use-after-free and out-of-bounds bugs. Linux already has the kmemcheck feature, but unlike kmemcheck, KASan uses compile-time instrumentation, which makes it significantly faster than kmemcheck. The main idea of KASAN is to use shadow memory to record whether each byte of memory is safe to access or not, and use compiler's instrumentation to check the shadow memory on each memory access. Address sanitizer uses 1/8 of the memory addressable in kernel for shadow memory and uses direct mapping with a scale and offset to translate a memory address to its corresponding shadow address. Code: [https://git.kernel.org/linus/0b24becc810dc3be6e3f94103a866f214c282394 commit], [https://git.kernel.org/linus/bebf56a1b176c2e1c9efe44e7e6915532cc682cf commit], [https://git.kernel.org/linus/c420f167db8c799d69fe43a801c58a7f02e9d57c commit], [https://git.kernel.org/linus/0316bec22ec95ea2faca6406437b0b5950553b7c commit], [https://git.kernel.org/linus/ef7f0d6a6ca8c9e4b27d78895af86c2fbfaeedb2 commit] == "lazytime" option for better update of file timestamps == Unix filesystems keep track of information about files, such as the last time a file was accessed or modified. Keeping track of this information is very expensive, specially the time when a file was accessed ("atime"), which encourages many people to disable it with the mount option "noatime". To alleviate this problem, the "relatime" mount option was added, the atime is only updated if the previous value is earlier than the modification time, or if the file was last accessed more than 24 hours ago. This behaviour, however, breaks some programs that rely on accurate access time tracking to work, and it's also against the POSIX standard. In this release, Linux adds another alternative: "lazytime". Lazytime causes access, modified and changed time updates to only be made in the cache. The times will only be written to the disk if the inode needs to be updated anyway for some non-time related change, if fsync(), syncfs() or sync() are called, or just before an undeleted inode is evicted from memory. This is POSIX compliant, while at the same time improving the performance. Recommended LWN article: [http://lwn.net/Articles/621046/ Introducing lazytime] Code: [https://git.kernel.org/linus/0ae45f63d4ef8d8eeec49c7d8b44a1775fff13e8 commit], [https://git.kernel.org/linus/1efff914afac8a965ad63817ecf8861a927c2ace commit], [https://git.kernel.org/linus/a26f49926da938f47561f386be56a83dd37a496d commit] == Multiple lower layers in overlayfs == In overlayfs, multiple lower layers can now be given using the the colon (":") as a separator character between the directory names. For example: mount -t overlay overlay -olowerdir=/lower1:/lower2:/lower3 /merged The specified lower directories will be stacked beginning from the rightmost one and going left. In the above example lower1 will be the top, lower2 the middle and lower3 the bottom layer. "upperdir=" and "workdir=" may be omitted, in that case the overlay will be read-only.

The pNFS architecture eliminates the scalability and performance issues associated with NFS servers deployed today. This is achieved by the separation of data and metadata, and moving the metadata server out of the data path. This release adds support for pNFS server, and drivers for the block layout with XFS support to use XFS filesystems as a block layout target, and the flexfiles layout. Also, in this release the NFS server defaults to NFS v4.2.
