You can discuss the latest Linux kernel changes on the New Linux Kernel Features Forum.
Linux 5.18 was released on Sunday, 22 May 2022.
Summary: This release includes support for user events, which allow processes to create and write to trace events that are isolated from kernel trace level events and will only provide trace information when the trace is enabled; support for Intel Indirect Branch Tracking on Intel CPUs, which helps to prevent some kinds of exploits; stricter memcpy() compile-time bounds checking, better process scheduling performance on AMD Zen processors; support for fprobe, which allows faster probing of function calls; some preparation work for header rearchitecting that will provide faster compilation times; support for Btrfs encoded I/O, cross-mount reflink/dedupe and performance improvements; and switch to the C11 standard. As always, there are many other features, new drivers, improvements and fixes.

1. Prominent features
1.1. Support for Indirect Branch Tracking on Intel CPUs
Indirect Branch Tracking is a feature found in Intel CPUs that attempts to improve security by forcing that functions called with indirect calls start with a specific ENDBR instruction. The instruction by itself does nothing, but if the code being called lacks it, the CPU will refuse to run it. The compiler inserts the required instructions where necessary to make this happen. This makes harder for a exploit (and proprietary modules) to call some random function.
Recommended LWN article: Indirect branch tracking for Intel CPUs
1.2. User events
Linux already has a method that allows tracing user space processes with the kernel tracing tools (uprobes). This release adds a new ABI that allow processes to create and write to trace events that are isolated from kernel trace level events. This enables a faster path for tracing from user mode data as well as opens managed code to participate in trace events, where stub locations are dynamic.
Processes often want to trace only when it's useful. A process can register an event describing the format of the event to the kernel. The kernel will create the event. The process will then receive a byte in a page mapping from a mapped tracefs file that it can check against. A privileged task can enable that event, which will change the mapped byte to true. The process can then start writing the event to the tracing buffer.

1.3. Better process scheduling performance on AMD Zen
Some CPUs, like AMD Zen, have multiple Last Level Caches per node with local memory channels and due to the allowed imbalance, it's far harder to tune some workloads to run optimally than it is on hardware that has 1 LLC per node. This release adjusts the imbalance on multi-LLC machines to allow an imbalance up to the point where LLCs should be balanced between nodes, which improves significantly the performance in some workloads.
1.4. fprobe, for probing multiple functions with a single probe handler
Linux already provices ways to probe function calls. This release includes a new one, fprobe, which is based on ftrace. The reasons why this new probe API exists is that it doesn't use the ftrace full features, it just provides a way to attach callbacks on function entry and exit. Unlike kprobes and kretprobes, fprobe gives faster+instrumentation for multiple functions with single handler.
Documentation: Fprobe - Function entry/exit probe
1.5. Headers rearchitecturing preparations for faster compilation times
A major rearchitecting of the kernel headers for significantly faster builds has been proposed; this release introduces some of these changes in the task scheduler.
1.6. Btrfs: Encoded I/O, cross-mount reflink/dedupe and performance improvements
The Btrfs file system supports transparent compression. When using send/receive, the sending side decompresses the data and the receiving side recompresses it before writing it out. This release lets user space tools avoid the extra decompression/compression by letting send/receive read and write compressed extents directly.
This release also adds support for cross-mount reflink/dedupe support, and several substantial performance improvements, especially for fsync-based workloads. There also are some preparations for the future extent tree v2 changes.
1.7. Stricter memcpy() compile-time bounds checking
This release implements stricter (no struct member overflows) bounds checking for memcpy(), memmove(), and memset() under CONFIG_FORTIFY_SOURCE. In order to eliminate a large class of common buffer overflow flaws that continue to persist in the kernel, these changes perform bounds checking of the destination struct member when they have a known size. This would have caught all of the memcpy()-related buffer write overflow flaws identified in at least the last three years
Recommended LWN article: Strict memcpy() bounds checking for the kernel
1.8. Switch to C11
The Linux kernel has relied until now on the C89 for various reasons. This release will switch to the C11 standard.

2. Core (various)
locking: Enable RT_MUTEXES by default on PREEMPT_RT commit
Allow to collect all CPUs backtraces during a panic event and also to enable "panic_print" in a kdump event commit, commit, commit
- Scheduler
- io_uring
Add support for ring messages. A new IORING_OP_MSG_RING command allows an SQE to signal another ring. That allows either waking up someone waiting on the ring, or even passing a 64-bit value via the user_data field in the CQE commit, commit
Lots of workloads use multiple threads, in which case the file table is shared between them, getting and putting the ring file descriptor for each io_uring_enter(2) system call is more expensive, as it involves an atomic get and put for each call. Similarly to how io_uring allows registering normal file descriptors to avoid this overhead, this release adds support for an io_uring_register(2) API that allows to register the ring fds themselves (IORING_REGISTER_RING_FDS and IORING_UNREGISTER_RING_FDS commands) commit
Support for NAPI poll on sockets commit
Make statx API stable commit
rseq: Remove broken uapi field layout on 32-bit little endian commit

3. File systems

(FEATURED) Encoded read/write ioctls, allows user space to read or write compressed raw data directly to extents, which avoids compression/recompression in some cases. Requires send tools that use the send/receive v2 ioctls commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

The fprobe API allows to attach probe on multiple functions at once very fast, because it works on top of ftrace. On the other hand this limits the probe point to the function entry or return commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

fprobe: Introduce fprobe function entry/exit probe commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
- libbpf
- tracing
(FEATURED) New user_events interface. User space can register an event with the kernel describing the format of the event. Then it will receive a byte in a page mapping that it can check against. A privileged task can then enable that event like any other event, which will change the mapped byte to true, telling the user space application to start writing the event to the tracing buffer commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
Add new ftrace_boot_snapshot kernel command line parameter. When set, the tracing buffer will be saved in the snapshot buffer at boot up when the kernel hands things over to user space. This will keep the traces that happened at boot up available even if user space boot up has tracing as well commit
Allow custom events to be added to the tracefs directory commit

vdpa: add two ioctl commands to support generic vDPA commit, commit
hv: balloon: Support status report for larger page sizes commit
8. Cryptography
Introduce a new Linux kernel keyring containing the TPM's Machine Owner Keys (MOK) called machine. In the mok side, the MokListTrustedRT UEFI variable can be set, from which kernel knows that MOK keys are kernel trusted keys and they are populated to the machine keyring. This keyring linked to the secondary trusted keyring, which means that can be used like any kernel trusted keys. This keyring of course can be used to hold other MOK'ish keys in other platforms in future. See instructions here. commit, commit, commit, commit, commit, commit, commit, commit

KEYS: remove support for asym_tpm keys commit
9. Security
- Random: Changes to the RNG's crypto, the intent for 5.18 has been to shore up the existing design as much as possible with modern cryptographic functions and proven constructions, rather than actually changing up anything fundamental to the RNG's design. So it's still the same old RNG at its core as before: it still counts entropy bits, and collects from the various sources with the same heuristics as before, and so forth. However, the cryptographic algorithms that transform that entropic data into safe random numbers have been modernized
Use RDSEED when we can rather than using RDRAND, and make sure RDRAND/RDSEED input always goes through the mixer rather than being xor'd into our state directly, in part in order to prevent ridiculous hypothetical cpu backdoors commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
