Linux 4.12 has been released on Sun, 2 July 2017.

Summary: This release includes a new BFQ I/O scheduler which provides a much better interactive experience; it also includes preliminary support for Radeon RX Vega graphic cards and support for USB Type-C connectors; improvements to the live kernel patching feature, support for Intel IMSM's Partial Parity Log which allows to close the RAID5 write hole; support for exposing OpenChannel SSDs as device blocks, and another I/O scheduler, Kybe that allows to configure a latency target for reads and writes, ,

1. Prominent features

1.1. Preliminary Radeon Vega support

This release adds preliminary support for Radeon RX Vega graphic cards.

Code: merge, commit, commit, commit

1.2. USB Type-C support

This release adds support for USB Type-C connectors. USB Type-C, commonly known as simply USB-C, is a 24-pin USB connector system allowing transport of data and energy.

1.3. New BFQ I/O scheduler for a more reponsive desktop

BFQ (Budget Fair Queuing) is a new I/O scheduler. For personal systems, BFQ provides low latency for interactive applications, low latency for soft real-time applications, higher speed for code-development tasks, high throughput, and strong fairness, bandwidth and delay guarantees. For servers, besides the same benefits as above, BFQ guarantees: audio and video-streaming with zero or very low jitter and drop rate; fast retrieval of WEB pages and embedded objects; real-time recording of data in live-dumping applications (e.g., packet logging); responsiveness in local and remote access to a server. For more details and benchmarks, see the Documentation or the project site

1.4. New Kyber I/O scheduler

The Kyber I/O scheduler is a low-overhead scheduler suitable for multiqueue and other fast devices. Given target latencies for reads and synchronous writes, it will self-tune queue depths to achieve that goal, similary to blk-wbt.

1.5. Progress in Live kernel patching

Live patching is a feature merged in Linux 4.0 that allows to patch the kernel code in running systems, which in turn allows to patch security issues without rebooting.

This release adds a so-called per-task consistency model - a foundation which will eventually enable to patch those ~10% of security patches which change function or data semantics. This is the biggest remaining piece needed to make livepatch more generally useful. This code stems from the design proposal made in November 2014. It's a hybrid of kGraft and kpatch: it uses kGraft's per-task consistency and syscall barrier switching combined with kpatch's stack trace switching.

1.6. Add support for Intel IMSM's Partial Parity Log

This release adds support for the Partial Parity Log feature found in Intel IMSM raid array. This feature is another way to close the RAID 5 Write Hole. PPL is available for md version-1 metadata and external (specifically IMSM) metadata arrays. It can be enabled using mdadm option --consistency-policy=ppl.

Documentation: Documentation/md/raid5-ppl.txt

Code: commit, commit, commit, commit, commit, commit

1.7. Expose OpenChannel SSDs as device blocks

This release introduces pblk, a host-side FTL for Open-Channel SSDs to expose them like block devices. Open-Channel SSDs are SSDs that do not include a Flash Translation Layer, support for them was included in Linux 4.4. pblk is an implementation of a Flash Transaction Layer in the Linux kernel, which allows data placement decisions, and I/O scheduling to be managed by the host, enabling users to optimize the SSD for their specific workloads.

Code: commit

2. Core (various)

• Change livepatch to use a basic per-task consistency model (FEATURED) commit, commit, commit

• epoll: Add busy poll support to epoll with socket fds. The main idea it is that when there is only one event left, the kernel will beging polling for events with the same NAPI ID commit, commit, commit, commit, commit, commit, commit, commit

4. Memory management

• Try to reduce fragmenting fallbacks commit, commit, commit, commit, commit, commit, commit, commit

• Print non-populated zones in /proc/zoneinfo commit

• MADV_FREE has several issues that make it unusable in software like jemalloc: doesn't support system without swap enabled, increases memory pressure, and accounting problems. This release puts MADV_FREE pages into the LRU_INACTIVE_FILE list, enables MADV_FREE for swapless systems and improves statistic accounting commit, commit, commit, commit, commit, commit

• memcontrol cgroup: introduced three new entries in memory.stat: workingset_refault (number of refaults of previously evicted pages), workingset_activate (number of refaulted pages that were immediately activated), workingset_nodereclaim (number of times a shadow node has been reclaimed) commit, commit

• memcontrol cgroup: provide shmem statistics commit

5. Block layer

• (FEATURED) introduce the BFQ-v0 I/O scheduler commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit ,commit, commit, commit, commit

• (FEATURED) introduce Kyber multiqueue I/O scheduler commit, commit

• CFQ scheduler: Disable writeback throttling (feature introduced in Linux 4.10) by default, since does not play well with CFQ since that also tries to throttle asynchronous writes. As a result asynchronous writeback can get starved in presence of readers [https://git.kernel.org/linus/142bbdfccc8b3e9f7342f2ce8422e76a3b45beae commit

• multiqueue: Export queue state through /sys/kernel/debug/block/*/state commit

• blk-throttle improvements: this release includes a scalable framework for implementing scalable priotization - particularly for blk-mq, but applicable to any type of block device. The interface is marked experimental for now commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• Device Mapper (DM)

  • Add integrity target. It emulates a block device that has additional per-sector tags that can be used for storing integrity information. The dm-integrity target can be used with the dm-crypt target - in this situation the dm-crypt target creates the integrity data and passes them to the dm-integrity target. In this mode, the dm-crypt and dm-integrity targets provide authenticated disk encryption - if the attacker modifies the encrypted device, an I/O error is returned. The dm-integrity target can also be used as a standalone target, in this mode it calculates and verifies the integrity tag internally. In this mode, the dm-integrity target can be used to detect silent data corruption on the disk or in the I/O path commit, commit, commit

  • dm crypt: Add a new authenticated encryption feature to the DM crypt target that builds on the capabilities provided by the DM integrity target. It allows the use of per-sector metadata, provided by the dm-integrity module, for integrity protection and persistently stored per-sector Initialization Vector (IV) commit, commit, commit

  • A major update for DM cache that reduces the latency for deciding whether blocks should migrate to/from the cache. The bio-prison-v2 interface supports this improvement by enabling direct dispatch of work to workqueues rather than having to delay the actual work dispatch to the DM cache core. So the dm-cache policies are much more nimble by being able to drive IO as they see fit. One immediate benefit from the improved latency is a cache that should be much more adaptive to changing workloads commit, commit, commit, commit
