• Linux_4.11

Last updated at 2017-12-30 01:29:52

Linux 4.11 has been released on Sun, 30 Apr 2017.

Summary: This release adds support for pluggable IO schedulers framework in the multiqueue block layer, journalling support in the MD RAID5 implementation that closes the write hole, a more scalable swapping implementation for swap placed in SSDs, a new statx() system call that solves the deficiencies of the existing stat(), a new perf ftrace tool that acts as a frontend for the ftrace interface, support for drives that implement the OPAL Storage Specification, support for the Shared Memory Communications-RDMA protocol as defined in RFC7609, persistent scrollback buffers for all VGA consoles, and many new drivers and other improvements.

1. Prominent features

1.1. Pluggable IO schedulers framework in the multiqueue block layer

The Linux block layer is know to have different IO schedulers (deadline, cfq, noop, etc) with different performance characteristics each one, and users are allowed to switch between them on the fly. In Linux 3.13, the block layer added a new multiqueue design that performs better with modern hardware (eg. SSD, NVM). However, this new multiqueue design didn't include support for pluggable IO schedulers.

This release solves that problem with the merge of a multiqueue-ready IO scheduling framework. A port of the deadline scheduler has also been added (more IO schedulers will be added in the future)

Code: merge, commit

1.2. Scalable swapping for SSDs

Modern storage devices such as SSDs are making the usage of swapping attractive not just as a way to deal with excessive memory load, but also as a performance enhancement technique. Cloud providers, for example, can overcommit memory more aggressively and fit more VMs to a platform with a fast swap device. However, the swapping implementation was designed for traditional rotating hard disks, where the performance and latency of the swap did not matter as much as it does with modern storage. This release makes the swap implementation more scalable, making it more suitable for use with modern storage devices.

1.3. Journaled RAID5 to close the write hole

Based in work started in Linux 4.4, this release adds journalling support to RAID4/5/6 in the MD layer (not to be confused with btrfs RAID). With a journal device configured (typically NVRAM or SSD), the "RAID5 write hole" is closed - a crash during degraded operations cannot result in data corruption.

Code: commit

1.4. statx(2), a modern stat(2) alternative

Due to several shortcomings in the stat(2) system call (like not being y2038 ready or not playing well with networking filesystems), a new system call has been worked through the years, with the final result being statx(2), a new system call that has been added in this release.

Code: commit

1.5. New perf ftrace tool

A new tool has been added to the perf toolkit: perf ftrace. This tool intends to be a simple perf front-end for the already existing ftrace interface. In this release, it only supports two tracers, function_graph or function (default tracer is function_graph, it can be configured in the ftrace.tracer config key). Only single thread tracing and the tool just reads trace_pipe in text and then write it to stdout. More features are expected in future releases.

Code: commit, commit, commit

1.6. Support for OPAL drives

The Opal Storage Specification is a set of specifications for features of data storage devices (such as disk drives) that enhance their security. For example, it defines a way of encrypting the stored data so that an unauthorized person who gains possession of the device cannot see the data. That is, it is a specification for self-encrypting drives.

This release adds Linux support for Opal nvme enabled controllers. It enables users to setup/unlock/lock locking ranges for SED devices using the Opal protocol.

Code: commit, commit

1.7. Support for the SMC-R protocol (RFC7609)

This release includes the initial part of the implementation of the "Shared Memory Communications-RDMA" (SMC-R) protocol as defined in RFC7609. SMC-R is an IBM protocol that provides RDMA capabilities over RoCE transparently for applications exploiting TCP sockets. While SMC-R does not aim to replace TCP, it taps a wealth of existing data center TCP socket applications to become more efficient without the need for rewriting them. A new socket protocol family PF_SMC is introduced. There are no changes required to applications using the sockets API for TCP stream sockets other than the specification of the new socket family AF_SMC. Unmodified applications can be used by means of a dynamic preload shared library.

SMC-R uses RDMA over Converged Ethernet (RoCE) to save CPU consumption. SMC-R inherits TCP qualities such as reliable connections, host-based firewall packet filtering (on connection establishment) and unmodified application of communication encryption such as TLS (transport layer security) or SSL (secure sockets layer). Since original TCP is used to establish SMC-R connections, load balancers and packet inspection based on TCP/IP connection establishment continue to work for SMC-R.

1.8. Persistent scrollback buffers for all VGA consoles

Not an important feature, specially for tmux/screen users, but probably annoying for many others: this release adds optional support for scrollback history not being flushed when switching between consoles (this breaks tools like clear_console that rely on flushing the scrollback history by switching back and forth between consoles which is why this feature is disabled by default. Use the escape sequence \e[3J instead for flushing the buffer)

For example, perf record -a --switch-output=2G will break the perf.data output into multiple files limited to 2GB of samples,and perf record -a --switch-output=1m will limit perf.data output files to 1 minute. Previous behaviour (--switch-output alone is now equivalent to perf record -a --switch-output=signal commit, commit

• TCP

  • Enables RACK loss detection (draft-ietf-tcpm-rack-01) to trigger fast recovery with a reordering timer. A few similar heuristics are no longer needed and are either removed or disabled to reduce the complexity of the Linux TCP loss recovery engine: 1) FACK (Forward Acknowledgement), 2) Early Retransmit (RFC5827), 3) thin_dupack (fast recovery on single DUPACK for thin-streams), 4) NCR (Non-Congestion Robustness RFC4653), and 5) Forward Retransmit. After this change, Linux's loss recovery algorithms consist of: 1) Conventional DUPACK threshold approach (RFC6675), 2) RACK and Tail Loss Probe (draft-ietf-tcpm-rack-01), 3) RTO plus F-RTO extension (RFC5682) commit, commit ,commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• sched: Introduce sample tc action. This action allows the user to sample traffic matched by tc classifier. The sampling consists of choosing packets randomly and sampling them using the psample module. The user can configure the psample group number, the sampling rate and the packet's truncation (to save kernel-user traffic) commit

• sched: cls_flower: Support matching on ARP, and hardware and protocol addresses for Ethernet hardware and IPv4 protocol addresses commit, commit

• netlink: Add the functionality for including address-family-specific per-link stats in RTM_GETSTATS messages. This is done through adding a new IFLA_STATS_AF_SPEC attribute under which address family attributes are nested and then the AF-specific attributes can be further nested commit

• Avoid receiving packets with an l3mdev on unbound UDP sockets. Also add a sysctl, udp_l3mdev_accept, to control this behaviour with it being analgous to the existing tcp_l3mdev_accept, namely to allow a process to have a VRF-global listen socket. Have this default to off as this is the behaviour that users will expect commit
