Linux 6.18 changelog.

Summary:

1. Prominent features

1.1. Improved kernel memory allocation performance with slub sheaves

Operating system kernels often need to allocate small amounts of memory, there is a mechanism called slab that does that. The Linux implementation is called Slub.

This release adds a feature called "sheaves", which could be described in essence as a per-CPU cache, so that allocations can be done locally most of the time. Previously, synchronization primitives were required that involved other CPUs. As a result, there is a performance improvement in both the allocation and freeing paths. It also adds support for kfree_rcu() batching and recycling.

1.2. A device mapper target for persistent cache

This release adds a pcache target which provides a mechanism to use persistent memory (e.g., CXL persistent memory, DAX-enabled devices) as a high-performance cache layer in front of traditional block devices such as SSDs or HDDs.

Documentation: dm-pcache — Persistent Cache

1.3. Process Namespaces as file handlers

The Linux kernel has supported "pidfds" (using file descriptors as stable handles to a process) since Linux 5.1. This has proven to be very useful.

In this release it is possible to encode and decode namespace file handles using the common name_to_handle_at() and open_by_handle_at() APIs. It has the same advantage as pidfds. It's possible to reliably and for the lifetime of the system refer to a namespace without pinning any resources and to compare them.

1.4. Support for Accurate Explicit Congestion Notification in TCP

This release includes initial support for Accurate Explicit Congestion Notification (currently a draft, which will be RFC 9768).

Explicit Congestion Notification (ECN) is a mechanism where network nodes can mark IP packets, instead of dropping them, to indicate incipient congestion to the endpoints. Receivers with an ECN-capable transport protocol feed back this information to the sender. ECN was originally specified for TCP in such a way that only one feedback signal can be transmitted per Round-Trip Time (RTT). Recent new TCP mechanisms need more Accurate ECN feedback information whenever more than one marking is received in one RTT.

This release adds support for a scheme that provides more than one feedback signal per RTT in the TCP header. It allows feeding back the number of Congestion Experienced marks accurately to the sender. Congestion control algorithms can take advantage of the accurate ECN information to fine-tune their congestion response to avoid drastic rate reduction when only mild congestion is encountered.

1.5. Add support for PSP encryption of TCP connections

PSP is a protocol out of Google. It shares some similarities with IPsec and TLS, but offers superior HW offloads capabilities. The protocol can work in multiple modes including tunneling.

Documentation: PSP Security Protocol

PSP paper: PSP_Arch_Spec.pdf

1.6. UDP receive performance improvements

This releases optimizes the UDP stack on the receive side, especially when under one or several UDP sockets are receiving a DDOS attack, by reducing contention, revisiting the binary layout of the involved data structs and implementing NUMA-aware locking. This improves UDP RX performance by an additional 50%, even more under extreme conditions.

1.7. BPF signed programs

This release implements the ability to load BPF programs that are cryptographically signed. Future development is in implementing security policies and paving the way for allowing unprivileged users to load vetted BPF programs.
