1. Prominent features
1.1. Kernel Concurrency Sanitizer
The Kernel Concurrency Sanitizer (KCSAN) is a dynamic data race detector for kernel space. KCSAN is a sampling watchpoint-based data race detector. Key priorities in KCSAN's design are lack of false positives, scalability, and simplicity. KCSAN uses compile-time instrumentation to instrument memory accesses and it is supported in both GCC and Clang
Documentation: The Kernel Concurrency Sanitizer (KCSAN)
Recommended LWN article: Concurrency bugs should fear the big bad data-race detector (part 1)
1.2. Kernel event notification mechanism
This release adds an event notification mechanism built on top of standard pipes whereby it effectively splices notification messages from the kernel into pipes opened by userspace. The pipe is opened in a special mode, and its internal buffer is used to hold messages generated by the kernel, which are then read out by read(2). The owner of the pipe tells the kernel which sources it would like to watch through that pipe, and filters may also be emplaced on a pipe so that certain source types and subevents can be ignored if they’re not of interest. In this release, the only event source is for keys/keyrings, such as linking and unlinking keys and changing their attributes, which will be used by Gnome.

1.3. Private procfs instances
Historically procfs was always tied to pid namespaces, this has the effect that all new procfs mounts are just a mirror of the internal one, any change, any mount option update, any new future introduction will propagate to all other procfs mounts in the same pid namespace.
This release allows to have several procfs mounts with different mounts options within the same pid namespace, the main aim of this work is to have on embedded systems one supervisor for apps. It also adds some convenient mount options that let a private procfs mount to show only ptraceable processes in the procfs, which allows to support lightweight sandboxes in Embedded Linux, or a mount option that allows to hide non-pid inodes.
2. Core (various)
Add Kernel Concurrency Sanitizer (KCSAN) commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
Add a general notification queue concept and add an event source for keys/keyrings, such as linking and unlinking keys and changing their attributes. Key/keyring notifications are desirable because if you have your kerberos tickets in a file/directory, your Gnome desktop will monitor that and tell you if your credentials cache changes. The notification queue is built on top of a standard pipe. Messages are effectively spliced in. The pipe is opened with a special flag: pipe2(fds, O_NOTIFICATION_PIPE). The pipe is then configured and messages are read out of the pipe. LSM hooks are included: A set of hooks are provided that allow an LSM to rule on whether or not a watch may be set, and a hook to allow an LSM to rule on whether or not a particular message may be posted to a particular queue commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
Add support for Clang's Shadow Call Stack mitigation, which uses a separately allocated shadow stack to protect against return address overwrites commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
namespaces: make it possible to use pidfds to attach to the namespaces of another process, i.e. they can be passed as the first argument to the setns(2) syscall. Multiple namespace flags can be specified in the second setns() argument and setns() will attach the caller to all the specified namespaces all at once or to none of them. The obvious example where this is useful is a standard container manager interacting with a running container: pushing and pulling files or directories, injecting mounts, attaching/execing any kind of process, etc. It also allows to switch to a set of namespaces atomically commit, commit, commit
- VFS
Add faccessat2(2) syscall. POSIX defines faccessat() as having a fourth "flags" argument, while the linux syscall doesn't have it. Glibc tries to emulate AT_EACCESS and AT_SYMLINK_NOFOLLOW, but AT_EACCESS emulation is broken. This release adds a new faccessat(2) syscall with the added flags argument and implement both flags commit
utimensat(2): AT_EMPTY_PATH support, this makes it possible to use utimensat on an O_PATH file (including symlinks) commit
Allow unprivileged whiteout creation commit
Have syncfs() return error when there are writeback errors commit, commit
Introduced the concept of local_locks, which are strictly per CPU and satisfy the constraints required by PREEMPT_RT commit, commit, commit, commit, commit, commit, commit
PM: allow to disable snapshot device commit
cgroup: add cpu.stat file to root cgroup commit
dynamic_debug: add an option to enable dynamic debug for modules only commit
- EFI
GOP: Add the ability to use a command-line option to switch the gop's display mode. The options supported are: video=efifb:mode=n to choose a mode; video=efifb:<xres>x<yres>[-(rgb|bgr|<bpp>)] to specify mode by resolution and optionally color depth; and video=efifb:auto to let the EFI stub choose the highest resolution mode available commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
Make initrd file loader configurable commit
Add a basic printf implementation for the EFI stub to use commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
init: allow to configure the default init commit

- memcg
Expose root cgroup's memory.stat commit
Add workingset_restore in memory.stat commit
Slow down swap allocation as the available space gets depleted. It adds a memory.swap.high knob, which can be used to protect the system from SWAP exhaustion. The mechanism used for penalizing is similar to memory.high penalty (sleep on return to user space) commit, commit, commit, commit
Optimize memory.numa_stat like memory.stat commit
Reworks memcg to charge swapin pages directly at swapin time, rather than at fault time, which may be much later, or not happen at all commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
Improvements about lowmem_reserve and /proc/zoneinfo commit, commit, commit

swap: improve swap scalability reduce lock contention on swap cache from swap slots allocation commit
swap: improve swap scalability by trying to scan more free slots even when fragmented commit
5. Block layer
loop: Add LOOP_CONFIGURE ioctl. This allows userspace to completely setup a loop device with a single ioctl, removing the in-between state where the device can be partially configured commit
Add support for Inline Encryption to the block layer. Inline Encryption hardware allows software to specify an encryption context (an encryption key, crypto algorithm, data unit num, data unit size, etc.) along with a data transfer request to a storage device, and the inline encryption hardware will use that context to en/decrypt the data. The inline encryption hardware is part of the storage device, and it conceptually sits on the data path between system memory and the storage device commit, commit, commit, commit, commit
- Device Mapper
dm crypt: support using encrypted keys commit
Add emulated block size target. Its main purpose is to emulate 512 byte sectors on 4K native disks commit

dm mpath: add Historical Service Time Path Selector. It keeps an exponential moving average of the service time for each path, and uses this along with the number of inflight requests to estimate future service time for a path commit
dm ebs: pass discards down to underlying device commit
dm bufio: implement discard commit
dm writecache: improve performance on DDR persistent memory (Optane) commit
dm-zoned: improve cache performance commit, commit, commit, commit, commit, commit

- CEPH
6. Tracing, perf and BPF
- BPF
Introduce CAP_BPF to split BPF operations that are allowed under CAP_SYS_ADMIN into combination of CAP_BPF, CAP_PERFMON, CAP_NET_ADMIN and keep some of them under CAP_SYS_ADMIN. The user process has to have: CAP_BPF to create maps and do other sys_bpf() commands, CAP_BPF and CAP_PERFMON to load tracing programs, and CAP_BPF plus CAP_NET_ADMIN to load networking programs commit, commit, commit
bpftool: Allow probing for CONFIG_HZ from kernel config commit

- SELinux
A number of improvements to various SELinux internal data structures to help improve performance commit, commit, commit
Add a new SELinux policy version which allows for a more space efficient way of storing the filename transitions in the binary policy. Given the default Fedora SELinux policy with the unconfined module enabled, this change drops the policy size from ~7.6MB to ~3.3MB. The kernel policy load time dropped as well commit
10. Networking

IPv6: Implement the upcoming rev of RFC4941 (IPv6 temporary addresses) commit
netlink: add infrastructure to expose policies to userspace commit
namespaces: enable to inherit devconf from current namespace. The goal is to be able to inherit the initial devconf parameters from the current netns, ie the netns where this new netns has been created. This is useful in a containers environment where /proc/sys is read only. For example, if a pod is created with specifics devconf parameters and has the capability to create netns, the user expects to get the same parameters than his 'init_net', which is not the real init_net in this case commit
Introduce netns_bpf for BPF programs attached to netnamespace commit

Add support for RTRS (RDMA Transport), a reliable high speed transport library which allows for establishing connection between client and server machines via RDMA. RTRS is multipath capable and provides I/O fail-over and load-balancing functionality. RNBD (RDMA Network Block Device) is a pair of kernel modules (client and server) that allow for remote access of a block device on the server over RTRS protocol commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

Fixes for SRBDS security issue. SRBDS is an MDS-like speculative side channel that can leak bits from the random number generator (RNG) across cores and threads. New microcode serializes the processor access during the execution of RDRAND and RDSEED. This ensures that the shared buffer is overwritten before it is released for reuse. This is equivalent to a full bus lock, which means that many threads running the RNG instructions in parallel have the same effect as the same amount of threads issuing a locked instruction targeting an address which requires locking of two cachelines at once commit, commit, commit, commit
