Linux 4.16 has been released on Sun, 1 Apr 2018.

Summary: Besides the latest code to deal with CPU security bugs, this release declares the reverse mapping and reflink features as stable, membarrier(2) adds expedited support, SMB3 Direct (RDMA) support, adds the x86 jailhouse hypervisor which is able to statically partition a multicore system into multiple so-called cells, support for PowerPC memory protection keys, the hypervisor part of AMD Secure Encrypted Virtualization; and many new drivers and other improvements.

1. Prominent features

1.1. Improved protection for CPU security bugs

This release adds:

• x86: Basic IBPB (Indirect Branch Prediction Barrier) support commit

• arm: Implement branch predictor hardening for Falkor and affected Cortex-A CPUs and Cavium ThunderX2 commit, commit, commit, commit

• arm: Add support for unmapping kernel when running in userspace (Kernel Page Table Isolation) commit

• kvm/x86: Add Indirect Branch Predictor Barrier (IBPB) is an indirect branch control mechanism. It keeps earlier branches from influencing later ones commit

• s390: An implementation of the array_index_mask_nospec function to the defense against spectre v1 commit

• s390: A s390 variant of the 'retpoline' spectre v2 defense called 'expoline' commit

• s390: Run user space and KVM guests with modified branch prediction commit

1.2. XFS reverse mapping and reflink features are now stable

The reverse mapping and reflink features, merged back in 4.8 and 4.9 respectively, have been declared stable. These features allow for cp --reflink=always support, data deduplication, data copy-on-write ...

Code: commit and reflink features commit

1.3. membarrier(2) expedited support

This release provides expedited command in membarrier(2) for registration and use of membarrier across processes communicating through shared memory mappings. The non-expedited command has proven to be really too slow (taking 10ms and more to complete) for real-world use. The expedited version completes in a matter of microseconds.

1.4. SMB3 Direct (RDMA) support

Starting with SMB2 dialect 3.0, Microsoft introduced SMB Direct transport protocol for transferring upper layer (SMB2) payload over RDMA via Infiniband, RoCE or iWARP. This release adds support for Linux.

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

1.5. Add the x86 jailhouse hypervisor

This release adds initial platform support for the jailhouse hypervisor. The Jailhouse hypervisor is able to statically partition a multicore system into multiple so-called cells. Linux is used as boot loader and continues to run in the root cell after Jailhouse is enabled. Linux can also run in non-root cells. Jailhouse was started 4 years ago as an open-source (GPL) light-weight hypervisor that statically partitions SMP systems. It's unique in that it uses one Linux instance, the root cell, as boot loader and management console. Jailhouse targets use cases for hard real-time and safety-critical systems that KVM cannot cater due to its inherent complexity

Code: commit

1.6. PowerPC: memory protection keys

This release adds support of memory protection keys (a feature merged in Linux 4.6) for Power7/8/9

Code: commit, commit

1.7. Second part of AMD Secure Encrypted Virtualization

This release adds the hypervisor part of AMD Secure Encrypted Virtualization, a feature that allows to encrypt the memory of virtualized guests so that the host can't see it.

• hardened usercopy whitelisting: Currently, hardened usercopy performs dynamic bounds checking on slab cache objects. This is good, but still leaves a lot of kernel memory available to be copied to/from userspace in the face of bugs. To further restrict what memory is available for copying, this creates a way to whitelist specific areas of a given slab cache object for copying to/from userspace, allowing much finer granularity of access control. Recommended LWN article: Hardened usercopy whitelisting. commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

Result of http://vger.kernel.org/~davem/seoul2017_netdev_keynote.pdf commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• TCP

  • Add ip6erspan collect_md mode commit, commit

• Add explicit support for GRO HW offloading commit, commit, commit, commit, commit

• Add flow table abstraction to netfilter. A new nf_flow_offload module is added that registers a hook at ingress. Every packet that hits the flow table is forwarded to where the flow table entry specifies in terms of destination/gateway and netdevice. In case of flow table miss, the packet follows the classic forward path. This flow table is populated via the new nftables VM action flow_offload, so the user can selectively specify what flows are placed into the flow table commit, commit, commit, commit, commit, commit, commit

• IPv6

  • Add support for non-equal-cost multipath routes commit, commit, commit, commit

  • Align nexthop behaviour with IPv4 commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

  • Add support for onlink flag (RTNH_F_ONLINK) on routes commit, commit, commit

  • ip6gretap: Similar to gre, vxlan, geneve, ipip tunnels, allow ip6gretap tunnels to operate in collect metadata mode commit, commit, commit

• devlink: Add support for resource abstraction commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• qdisk: Currently the filters added to qdiscs are independent, eg if you have 2 netdevices and you create ingress qdisc on both and you want to add identical filter rules both, you need to add them twice. This release allows to make things easier and saves resources allowing to share all filters within a qdisc commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• xdp: new XDP rx-queue info concept commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

  • nf_nat_snmp_basic: remove debug parameter commit

• BFP

  • Add support for creating maps on networking devices. BPF is programs+maps, the pure program offload has been around for quite some time, this adds the map part of the equation commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

  • Allow arbitrary function calls from bpf function to another bpf function commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

  • Add the ability to do BPF directed error injection. A lot of our error paths are not well tested because there is no good way of injecting errors generically. Some subystems have ways to inject errors, but they are random so it's hard to get reproduceable results. With this mechanism it is possible to add determinism to our error injection commit, commit, commit, commit, commit

  • Implement syscall command BPF_MAP_GET_NEXT_KEY for stacktrace map commit, commit

  • Implements MAP_GET_NEXT_KEY command for LPM_TRIE map. This command is really useful for key enumeration, and for key deletion if what keys in the trie are unknown
