c4e20cad - sys/sys: further adoption of SPDX licensing ID tags.

sys/sys: further adoption of SPDX licensing ID tags.Mainly focus on files that use BSD 2-Clause license, however the tool Iwas using misidentified many licenses so this was mostly a manual - errorprone - task.The Software Package Data Exchange (SPDX) group provides a specificationto make it easier for automated tools to detect and summarize well knownopensource licenses. We are gradually adopting the specification, notingthat the tags are considered only advisory and do not, in any way,superceed or replace the license texts.

4ec73712 - For vendors like Juniper, extensibility for sockets is important. A

Mon, 18 Aug 2014 23:45:40 +0000

For vendors like Juniper, extensibility for sockets is important. Agood example is socket options that aren't necessarily generic. Tothis end, OSD is added to the socket structure and hooks are definedfor key operations on sockets. These are:o soalloc() and sodealloc()o Get and set socket optionso Socket related kevent filters.One aspect about hhook that appears to be not fully baked is the returnsemantics (the return value from the hook is ignored in hhook_run_hooks()at the time of commit). To support return values, the socket_hhook_datastructure contains a 'status' field to hold return values.Submitted by: Anuranjan Shukla Obtained from: Juniper Networks, Inc.

- Introduce the Hhook (Helper Hook) KPI. The KPI is closely modelled on pfil(9), and in many respects can be thought of as a more generic superset of pfil. Hhook provides a way for kernel subsystems to export hook points that Khelp modules can hook to provide enhanced or new functionality to the kernel. The KPI has been designed to ensure hook points pose no noticeable overhead when no hook functions are registered.- Introduce the Khelp (Kernel Helpers) KPI. Khelp provides a framework for managing Khelp modules, which indirectly use the Hhook KPI to register their hook functions with hook points of interest within the kernel. Khelp modules aim to provide a structured way to dynamically extend the kernel at runtime in an ABI preserving manner. Depending on the subsystem providing hook points, a Khelp module may be able to associate per-object data for maintaining relevant state between hook calls.- pjd's Object Specific Data (OSD) KPI is used to manage the per-object data allocated to Khelp modules. Create a new "OSD_KHELP" OSD type for use by the Khelp framework.- Bump __FreeBSD_version to 900028 to mark the introduction of the new KPIs.In collaboration with: David Hayes and Grenville Armitage Sponsored by: FreeBSD FoundationReviewed by: bz, others along the wayMFC after: 3 months List of files: /freebsd-14.2/sys/sys/khelp.h
