1. Coolest features
1.1. New version 5.0
This release increases the major version number to 5. This change does not mean anything and does not affect programs in any way, it just makes Linus happy.
1.2. Energy-aware Scheduling for Arm big.LITTLE
This release includes the energy-aware scheduling feature, which lets the task scheduler to take scheduling decisions that will result in lower power usage on asymmetric SMP platforms - such as waking up tasks to the more energy-efficient CPUs first. This feature is important to achieve better power management in phones using Arm's big.LITTLE CPUs. This feature is a simplified version of the energy-aware scheduling that is currently part of the AOSP Common Kernel.

1.3. Adiantum file system encryption for low power devices
This release adds support for the Adiantum encryption. Note that this encryption mode is not added to ecryptfs but to fscrypt, the kernel funcionality which filesystems (currently ext4, f2fs and ubifs) can hook into to support transparent encryption of files and directories.
Adiantum was developed to provide filesystem encryption for low-end Android devices that lack AES instructions. On ARM Cortex-A7, on 4096-byte messages Adiantum encryption is about 4 times faster than AES-256-XTS encryption; decryption is about 5 times faster. See the google security blog or the Adiantum paper for more details.
Recommended LWN article: Adiantum: encryption for the low end
1.4. Support for AMDGPU FreeSync
This release adds support for FreeSync, an adaptive synchronization technology for LCDs that support a dynamic refresh rate, aimed at providing a low monitor latency and a smooth, virtually stutter-free viewing experience. It also helps improve battery life by reducing the refresh rate of the panel when not receiving new images.
Variable refresh rate capable displays can dynamically adjust their refresh rate by extending the duration of their vertical front porch until page flip or timeout occurs. This can reduce or remove stuttering and latency in scenarios where the page flip does not align with the vblank interval. An example scenario would be an application flipping at a constant rate of 48Hz on a 60Hz display. The page flip will frequently miss the vblank interval and the same contents will be displayed twice. This can be observed as stuttering for content with motion. If variable refresh rate was active on a display that supported a variable refresh range from 35Hz to 60Hz no stuttering would be observable for the example scenario.

1.5. UDP Generic Receive Offload and MSG_ZEROCOPY support
This release adds support of GRO (Generic Receive Offload) in the UDP implementation. A new sockopt (UDP_GRO) has been added to enable GRO support. Future enachements will enable UDP GSO offload on more virtual devices eventually even on forwarded packets.
This release also expands MSG_ZEROCOPY support for UDP. Recommended LWN article: Zero-copy networking
Code: GRO commit, commit, commit, commit, commit, commit, commit, commit, commit, msg_zerocopy commit, commit, commit
1.6. Support cpuset resource controller in cgroupv2
The cpuset controller provides a mechanism for constraining the CPU and memory node placement of tasks to only the resources specified in the cpuset interface files in a task's current cgroup. This is especially valuable on large NUMA systems where placing jobs on properly sized subsets of the systems with careful processor and memory placement to reduce cross-node memory access and contention can improve overall system performance.
This release enables cpuset controller in cgroup v2, with a minimal set of features.
Code: commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
1.7. Btrfs swap file support
Btrfs removed support for swap files a decade ago. However, now the proper restrictions are in place, Btrfs can support swap files. The swap file must be fully allocated as "nocow" with no compression on one device.
Code: commit
1.8. binderfs, a binder filesystem to run multiple instances of Android
This release includes binderfs, a pseudo-filesystem for the Android Binder IPC driver. Each ipc namespace will mount a new binderfs instance. It is backwards compatible, and it allows to run multiple of Android. Each binderfs mount initially only contains a binder-control device. It can be used to dynamically allocate new binder IPC devices via ioctls.
Code: commit
1.9. ARM pointer authentication
The ARMv8.3 Pointer Authentication extension adds primitives that can be used to mitigate certain classes of attack where an attacker can corrupt the contents of some memory (e.g. the stack). The extension uses a Pointer Authentication Code (PAC) to determine whether pointers have been modified unexpectedly. A PAC is derived from a pointer, another value (such as the stack pointer), and a secret key held in system registers.
The extension adds instructions to insert a valid PAC into a pointer, and to verify/remove the PAC from a pointer. The PAC occupies a number of high-order bits of the pointer, which varies dependent on the configured virtual address size and whether pointer tagging is in use. A subset of these instructions have been allocated from the HINT encoding space. In the absence of the extension (or when disabled), these instructions behave as NOPs. Applications and libraries using these instructions operate correctly regardless of the presence of the extension.
For more details see the documentation: Documentation/arm64/pointer-authentication.txt

2. Core (various)
(FEATURED) task scheduler: Introduces Energy Aware Scheduling for CFS tasks on platforms with asymmetric CPU topologies (e.g. Arm big.LITTLE) commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
fanotify: Currently, the fanotify API does not provide a means for user space applications to receive events when a file has been opened specifically for execution. New event masks FAN_OPEN_EXEC and FAN_OPEN_EXEC_PERM have been introduced in this release for this purpose commit, commit, commit, commit
(FEATURED) Enable cpuset controller in default hierarchy commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
(FEATURED) binder: implement binderfs, a pseudo-filesystem for the Android Binder IPC driver which can be mounted per-ipc namespace allowing to run multiple instances of Android. Each binderfs mount initially only contains a binder-control device. It can be used to dynamically allocate new binder IPC devices via ioctls commit
cgroup: Add named hierarchy disabling to cgroup_no_v1 boot param commit
(FEATURED) fscrypt: add support for the Adiantum encryption mode. Adiantum is a tweakable, length-preserving encryption mode with security provably reducible to that of XChaCha12 and AES-256, subject to a security bound. It's also a true wide-block mode, unlike XTS commit

3. File systems
- BTRFS

- F2FS
Add an ioctl() to explicitly trigger fsck later commit
- AUTOFS
Add strictexpire mount option commit
4. Memory management
Add a new software tag-based mode to KASAN. The plan is to implement HWASan for the kernel with the incentive, that it's going to have comparable to KASAN performance, but in the same time consume much less memory, trading that off for somewhat imprecise bug detection and being supported only for arm64 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
Fragmentation avoidance improvements, reducing fragmentation events by over 90%, resulting in better transparent hugepage (THP) usage commit, commit, commit, commit
Speed up mremap(2) by 20x on large regions by copying page tables at the PMD level even for non-THP systems, for now on x86 commit, commit, commit
kmemleak: add config to select auto scan commit
Change mincore() to count "mapped" pages rather than "cached" pages commit This was later reverted and different solution is in the works for 5.1+ commit More on LWN Defending against page-cache attacks and Fixing page-cache side channels, second attempt

Improve Out Of Memory (OOM) reports, include victim's memcg commit commit
Fix a long-standing issue where waiting for a page to migrate will effectively disrupt the migration, resulting in e.g. memory offline failures for busy pages such as those containing shared libraries commit
zram improvements, including the ability to mark a zram slot as idle, which is cleared once there is IO for the slot, which can help estimate wasted memory, and perform writeback that will free it. Also introduce writeback limits, see the respective commits for details. commit commit commit commit commit commit commit commit
THP eligibility reporting in /proc/pid/smaps and /proc/pid/status that allows precisely determining for each process and mapping if THP is disabled due to madvise(MADV_NOHUGEPAGE) or prctl(PR_SET_THP_DISABLE) commit commit, commit
page-alloc: reduce zone->lock contention commit
5. Block layer
Add support for multiple queue maps for blk-mq. Since blk-mq was introduced, it's only support a single queue map. This means you can have 1 set of queues, and the mapping purely depends on what CPU an IO originated from. With this patch set, drivers can implement mappings that depend on both CPU and request type - and they can have multiple sets of mappings. NVMe is used as a proof of concept commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
Remove all the non-mq code. Remaining drivers have been converted 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, commit, commit, commit, commit, commit

raid6: add option to skip algo benchmarking commit
null_blk: Add conventional zone configuration for zoned support commit
zram idle page writeback. On zram-swap usecase, zram has usually many idle/huge swap pages. It's pointless to keep in memory(ie, zram). To solve the problem, this feature introduces idle/huge page writeback to backing device so the goal is to save more memory space on embedded system commit, commit, commit, commit, commit, commit, commit
6. Tracing, perf and BPF
- BPF
Support raw tracepoints in modules commit
Add perf-based event notification for sock_ops. The eBPF kernel module can thus be designed to apply any desired filters to the bpf_sock_ops and trigger a perf-event notification based on the verdict from the filter. The uspace component can use these perf-event notifications to either read any state managed by the eBPF kernel module, or issue a TCP_INFO netlink call if desired commit, commit
Add support for mapinmap in libbpf, a helper for libbpf which would allow it to load map-in-map(BPF_MAP_TYPE_ARRAY_OF_MAPS and BPF_MAP_TYPE_HASH_OF_MAPS) commit, commit
Introduce bpf_line_info. It will be useful for introspection purpose commit, commit, commit, commit, commit, commit
Add func info support to the kernel so we can get better ksym's for bpf function calls. Basically, function call types are passed to kernel and the kernel extract function names from these types in order to contruct ksym for these functions commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
Add BPF_F_ANY_ALIGNMENT , an "any alignment" flags to tell the verifier to forcefully disable it's alignment checks completely. It's needed by SPARC commit

trace: Allow suppressing the syscall argument names commit
Add JSON metrics for Cascadelake server commit
Unify dynamic event interface on ftrace. Currently ftrace has 3 dynamic event interfaces, kprobes, uprobes and synthetic. This series unifies those dynamic event interfaces to "dynamic_events" so that we can add other dynamic events easily on same interface, e.g. function events. The older interfaces are left on the tracefs for backward compatibility commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
Add tracefs file buffer_percentage that allows users to specify how much of the buffer (percentage of pages) need to be filled before waking up a task blocked on a per cpu trace_pipe_raw file commit

8. Cryptography
Support incremental algorithm dumps commit
(FEATURED) adiantum: add Adiantum support commit
chacha: add XChaCha12 support commit
chacha20-generic: add XChaCha20 support commit
9. Security
Add seccomp trap to userspace. It introduces a means for syscalls matched in seccomp to notify some other task that a particular filter has been triggered. The motivation for this is primarily for use with containers. For example, if a container does an init_module(), we obviously don't want to load this untrusted code, which may be compiled for the wrong version of the kernel anyway. Instead, we could parse the module image, figure out which module the container is trying to load and load it on the host. As another example, containers cannot mknod(), since this checks capable(CAP_SYS_ADMIN). However, harmless devices like /dev/null or /dev/zero should be ok for containers to mknod, but we'd like to avoid hard coding some whitelist in the kernel. Another example is mount(), which has many security restrictions for good reason, but configuration or runtime knowledge could potentially be used to relax these restrictions.

VRF: allow simultaneous service instances in default and other VRFs. It provides this isolation for stream sockets subject to the existing kernel parameter net.ipv4.tcp_l3mdev_accept not being set, given that this is documented as allowing a single service instance to work across all VRF domains. Similarly, net.ipv4.udp_l3mdev_accept is checked for datagram sockets, and net.ipv4.raw_l3mdev_accept is introduced for raw sockets. The functionality applies to UDP & TCP services as well as those using raw sockets, and is for IPv4 and IPv6 commit, commit, commit, commit, commit, commit, commit, commit, commit

Announce radios/interfaces when switching namespaces, so userspace can rely on these events to discover radios properly commit
Add a new "peer measurement" API, that can be used to measure certain things related to a peer. Right now, only implement FTM (flight time measurement) over it, but the idea is that it'll be extensible to also support measuring the necessary things to calculate e.g. angle-of-arrival for WiGig commit, commit

Add support for speculation barrier instruction As part of the fallout from specdown and meltre, Armv8.5 introduces an architected Speculation Barrier (SB) instruction.

Add support for 52-bit userspace VAs to systems that have ARMv8.2-LVA and are running with a 48-bit VA_BITS and a 64KB page size. If no hardware support is present, the kernel runs with a 48-bit VA space for userspace. Userspace can exploit this feature by providing an address hint to mmap where addr[51:48] != 0. Otherwise all the VA mappings will behave in the same way as a 48-bit VA system (this is to maintain compatibility with software that assumes the maximum VA size on arm64 is 48-bit) commit, commit, commit, commit, commit, commit, commit,

12. Drivers
12.1. Graphics
(FEATURED) A DRM API for adaptive sync and variable refresh rate support. Adaptive sync is part of the DisplayPort specification and allows for graphics adapters to drive displays with varying frame timings. Variable refresh rate (VRR) is essentially the same, but defined for HDMI commit, commit, commit, commit, commit
VESA has developed an industry standard Display Stream Compression (DSC) for interoperable, visually lossless compression over display links to address the needs for higher resolution displays. This patch series enables DSC on Gen 10 eDP and Gen 11 eDP/DP panels. This implementation is based on VESA DP 1.4 and DSC specifications commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
