Comprehensible changelog of the linux kernel, inspired by [http://wiki.dragonflybsd.org/index.php/DragonFly_Status Dragonfly's status]. Another good places to get more information about the linux kernel are [http://www.kernel-traffic.org Kernel traffic] and [http://www.lwn.net LWN] and their [http://lwn.net/Kernel/ "kernel status" articles], [http://lwn.net/Articles/driver-porting/ driver porting guide] - many of the links here are linking to LWN articles and we wouldn't have been able to restore the 2.5.x-2.6.x changelog without them (you may be insterested in subscribing so Jonathan can keep up the good work ;) ) 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.

1. Prominent features
1.1. Long Term Support
This release is a Long Term Support release, which means that maintainers will provide bugfixes for this kernel revision for a much longer period of time than for other stable kernel releases.
1.2. Ext4 fast commit support, for faster metadata performance
Many applications use fsync(2) to ensure that data is reliably placed on disk. Such operation attempts to synchronize to the disk a few more metadata than expected. In this release, Ext4 will use a novel journaling technique, consisting in optimistically only journal the minimum required information through which a crash recovery operation can recover the metadata modified through an fsync operation. This speeds up fsync() and metadata heavy operations. This feature needs to be enabled at mkfs time.
Recommended LWN article: Fast commits for ext4
1.3. Support io_uring restrictions to facilitate secure sharing of rings
Since io_uring was introduced in Linux 5.1, it has seen widespread adoption. As usual, widespread adoption leads to new use cases, such as processes that might want share a ring with less trusted processes. This release adds a few API changes that add some restrictions and make possible for host application to grant access to some of its file descriptors and allow untrusted applications or guests to safely use io_uring.
Recommended LWN article: Operations restrictions for io_uring
1.4. Memory hints for other processes
Processes in Linux can use the madvise() system call to inform the kernel about their behaviour in order to get better performance. However, in some platforms (e.g., Android), the information required to make the hinting decision is not known to the process. Instead, it is known to a centralized userspace daemon(e.g., ActivityManagerService), and that daemon must be able to initiate memory reclaim on its own without any app involvement. To solve the concern, this patch introduces new syscall - process_madvise(2). Basically, it's same with madvise(2) syscall, except that it requires a pidfd of a target process, and for now it supports a more limited set of possible memory hints.
Recommended LWN article: process_madvise(), pidfd capabilities, and the revenge of the PIDs
1.5. Faster performance and memory consumption in virtio-fs
virtio-fs was added in Linux 5.4 as a solution to share parts of the host file systems with guest VMs in a high-performance, API-compatible way. In this release, virtio-fs adds supports for DAX, which allows bypassing guest page cache and allows mapping host page cache directly in guest address space. This can speed up things considerably in many situations. Also this can result in substantial memory savings as file data does not have to be copied in guest and it is directly accessed from host page cache.
1.6. AMD support for encryption of register in virtualized guests
Linux supports SEV since Linux 4.15. SEV is an AMD feature that encrypts the memory of virtualized guests, such that hosts can't access it unencrypted. This release enhances it by also encrypting the guest register state, making the registers inaccessible to the hypervisor by en-/decrypting them on world switches. Thus, it adds additional protection to Linux guests against exfiltration, control flow and rollback attacks. With SEV-ES, the guest is in full control of what registers the hypervisor can access.
1.7. Static calls for improved post-Spectre performance
Static calls are a replacement for global function pointers. They use code patching to allow direct calls to be used instead of indirect calls. They give the flexibility of function pointers, but with improved performance. This is especially important for cases where retpolines would otherwise be used, as retpolines can significantly impact performance. The new APIs are utilized in the x86 perf code, a heavy user of function pointers, where static calls speed up the PMU handler by 4.2%.
Recommended LWN article: Relief for retpoline pain
1.8. Support ARM Memory Tagging Extension
Memory Tagging Extension (part of the ARMv8.5 Extensions) provides a mechanism to detect the sources of memory related errors which may be vulnerable to exploitation, including bounds violations, use-after-free, use-after-return, use-out-of-scope and use before initialization errors.
Recommended LWN article: The Arm64 memory tagging extension in Linux
2. Core (various)
Add a nosymfollow mount option, disables symbolic link resolution in specified mounts commit
Support non-blocking pidfds. Passing a non-blocking pidfd to waitid() currently has no effect, i.e. is not supported. There are users which would like to use waitid() on pidfds that are O_NONBLOCK and mix it with pidfds that are blocking and both pass them to waitid(). Non-blocking pidfds will return EAGAIN from waitid() when no child process is ready yet commit, commit, commit, commit
fs: Prepare for upcoming Casefolding/Encryption commit, commit, commit, commit

It will allow to store and read messages in any situation wihtout the risk of deadlocks and without the need of temporary per-CPU buffers. Recommended LWN article commit, commit, commit, commit
- Locking

rseq/membarrier: add MEMBARRIER_CMD_PRIVATE_EXPEDITED_RSEQ. It issues an IPI to a CPU, restarting a potentially active RSEQ critical section on the CPU commit, commit, commit
seqlock: Introduce seqcount_latch_t. Latch sequence counters are a multiversion concurrency control mechanism where the embedded seqcount_t counter even/odd value is used to switch between two copies of protected data. This allows the sequence counter read side to be invoked from NMIs and safely interrupt its own write side critical section commit, commit, commit, commit, commit, commit, commit, commit

(FEATURED) Add static_call(), which uses the idea of static_branch() applied to indirect function calls. Remove a data load (indirection) by modifying the text. The new APIs are utilized in the x86 perf code, a heavy user of function pointers, where static calls speed up the PMU handler by 4.2% commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

fonts: add font 6x8 for OLED display commit
Add backtrace_idle parameter to force backtrace of idle CPUs commit
FUSE: Auto-mounted submounts. virtiofsd just passes through the stat.st_ino value from the host to the guest, without taking stat.st_dev into account. Therefore, it is generally impossible to uniquely identify nodes in the guest by their st_dev/st_ino combinations. This release allows to pass through st_dev alongside st_ino: It lets the guest create auto-mounted submounts for every host mount point, so that they get their own dedicated st_dev. This is similar to what NFS does with the crossmnt option commit, commit, commit, commit, commit, commit

IPv4: Allow more than 255 IPv4 multicast interfaces commit, commit, commit
TCP: Allow to reflect TOS value received in SYN, and send it out in SYN-ACK, and eventually set the TOS value of the established socket with this reflected TOS value.
