1. Prominent features
1.1. Landlock security module
Landlock is a new Linux security module that allows to sandbox applications. The goal of Landlock is to enable to restrict ambient rights (e.g. global filesystem access) for a set of processes. Because Landlock is a stackable LSM, it makes possible to create safe security sandboxes as new security layers in addition to the existing system-wide access-controls. This kind of sandbox is expected to help mitigate the security impact of bugs or unexpected/malicious behaviors in user-space applications. Landlock empowers any process, including unprivileged ones, to securely restrict themselves.
Landlock is inspired by seccomp-bpf but instead of filtering syscalls and their raw arguments, a Landlock rule can restrict the use of kernel objects like file hierarchies, according to the kernel semantic. Landlock also takes inspiration from other OS sandbox mechanisms: XNU Sandbox, FreeBSD Capsicum or OpenBSD Pledge/Unveil.
In this current form, Landlock misses some access-control features. This enables to minimize this patch series and ease review. This series still addresses multiple use cases, especially with the combined use of seccomp-bpf: applications with built-in sandboxing, init systems, security sandbox tools and security-oriented APIs
Recommended LWN article: Sandboxing with the Landlock security module
1.2. Support for Clang Control Flow Integrity
This release builds on last cycle's LTO work, and allows the arm64 kernels to be built with Clang's Control Flow Integrity feature, which is designed to abort the program upon detecting certain forms of undefined behavior that can potentially allow attackers to subvert the program’s control flow. This feature has happily lived in Android kernels for almost 3 years. CFI support for x86 is still under development, but is pretty close.
Recommended LWN article: Control-flow integrity for the kernel
1.3. Support for randomising the stack address offset in each syscall
This release supports randomized stack offsets per syscall to make stack-based attacks harder which rely on the deterministic stack layout. The feature is based on the original idea of PaX's RANDSTACK feature, but uses a significantly different implementation.
The feature is guarded with a static branch which avoids the overhead when disabled. As of this release this is supported for X86 and ARM64.
1.4. Support for concurrent TBL flushing
Currently, local and remote TLB flushes are not performed concurrently, which introduces unnecessary overhead - each INVLPG can take 100s of cycles. This patch-set allows TLB flushes to be run concurrently: first request the remote CPUs to initiate the flush, then run it locally, and finally wait for the remote CPUs to finish their work. In testing this improved sysbench performance measurably by a couple of percentage points, especially if TLB-heavy security mitigations are active.
1.5. Preparatory Apple M1 support
This kernel includes initial support for the Apple M1 platform. The Apple M1 is the processor used it all current generation Apple Macintosh computers. Support for this platform so far is rudimentary, but it boots and can use framebuffer and serial console over a special USB cable.
Support for several essential on-chip devices (USB, PCIe, IOMMU, NVMe) is work in progress but was not ready in time for this release.
A very detailed description of what works is in the commit messages and on the AsahiLinux wiki
1.6. Support for incoming AMD and Intel graphics chips
This release includes initial support for future Intel and AMD chips, such as Intel Alderlake S or AMD Adebaran support
1.7. BPF support for calling kernel functions directly
This release allows bpf programs calling kernel functions (initially to reuse TCP congestion control implementations)
Recommended LWN article: Calling kernel functions from BPF
1.8. A virtio sound driver for improved sound experience on virtualized guests
This release implements a driver part of the virtio sound device specification.
The driver supports PCM playback and capture substreams, jack and channel map controls. A message-based transport is used to write/read PCM frames to/from a device.
As a device part was used OpenSynergy proprietary implementation.
1.9. io_uring support for multi shot mode
Support for multi-shot poll. This allows arming a poll request for a given event mask, and then have it trigger multiple times. The default behavior for io_uring POLL_ADD has been one-shot, where one SQE issued will result in one CQE filled (when the event triggers) and termination of the poll request after that. With multi-shot, one POLL_ADD will generate a CQE every time the event triggers.
1.10. Add misc cgroup
This implements generic support for misc resources which can be controlled by simply counting and limiting the number of resource instances - ie there's X number of these on the system and this cgroup subtree can have upto Y of those.
The first user is the address space IDs used for virtual machine memory encryption and expected future usages are similar - niche hardware features with concrete resource limits and simple usage models
2. Core (various)
(FEATURED) cgroup: New misc cgroup controller commit, commit, commit
(FEATURED) Optionally randomize kernel stack offset each syscall commit, commit, commit, commit, commit, commit
(FEATURED) Concurrent TLB flushing commit, commit, commit, commit, commit, commit, commit, commit
softirq: Real Time awareness commit, commit, commit, commit, commit, commit
- fanotify
- io_uring
(FEATURED) 1) Support for multi-shot poll. This allows arming a poll request for a given event mask, and then have it trigger multiple times, 2) support for POLL_ADD updates. This allows updating the event mask (only) of an existing poll request, both one-shot and multi-shot commit, commit, commit, commit, commit, commit, commit, commit
1) support dynamic managment for registered buffers, including update. Add new IORING_REGISTER* for rsrc register and rsrc update, which are just dispatch files/buffers to right callbacks 3) add rsrc tagging, with tag=0 ignoring CQE posting commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

- Locking
- Task scheduler
Add 'scheduler latency debugging': warn after long periods of pending need_resched. This is an opt-in feature that requires the enabling of the LATENCY_WARN scheduler feature, or the use of the resched_latency_warn_ms=xx boot parameter commit

- kbuild
- kconfig
modules: add CONFIG_MODPROBE_PATH to allow configuring the "/sbin/modprobe" path commit
Adds a special-case when waiting on a pid (via waitpid, waitid, wait4, etc) to avoid doing an O(n) scan of children and tracees, and instead do an O(1) lookup. This can make a substantial performance improvement for applications with a thread that has many children or tracees and frequently needs to wait on them. Tools that use ptrace to intercept syscalls for a large number of processes are likely to fall into this category commit
kbuild: add CONFIG_VMLINUX_MAP expert option. It can be quite useful to have ld emit a link map file, in order to debug or verify that special sections end up where they are supposed to commit

Introduce prctl(PR_PAC_{SET,GET}_ENABLED_KEYS), which allows the user program to control which PAC keys are enabled in a particular task. The main reason why this is useful is to enable a userspace ABI that uses PAC to sign and authenticate function pointers and other pointers exposed outside of the function, while still allowing binaries conforming to the ABI to interoperate with legacy binaries that do not sign or authenticate pointers. The idea is that a dynamic loader or early startup code would issue this prctl very early after establishing that a process may load legacy binaries, but before executing any PAC instructions commit

Add AMD SEV guest live migration support commit, commit, commit, commit, commit, commit, commit
Adds the simple idea of tagging shadow-present SPTEs with a single bit, instead of looking for non-zero SPTEs that aren't MMIO and aren't REMOVED. Doing so reduces KVM's code footprint by 2k bytes on x86-64, and presumably adds a tiny performance boost in related paths commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
