* Make timespecadd(3) and friends publicAlan Somers2018-07-301-16/+2
| | | | | | | | | | | | | | | | | | | | | | The timespecadd(3) family of macros were imported from NetBSD back in r35029. However, they were initially guarded by #ifdef _KERNEL. In the meantime, we have grown at least 28 syscalls that use timespecs in some way, leading many programs both inside and outside of the base system to redefine those macros. It's better just to make the definitions public. Our kernel currently defines two-argument versions of timespecadd and timespecsub. NetBSD, OpenBSD, and FreeDesktop.org's libbsd, however, define three-argument versions. Solaris also defines a three-argument version, but only in its kernel. This revision changes our definition to match the common three-argument version. Bump _FreeBSD_version due to the breaking KPI change.

* Add a new socket option SO_TS_CLOCK to pick from several different clockMaxim Sobolev2017-01-162-1/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sources to return timestamps when SO_TIMESTAMP is enabled. Two additional clock sources are: o nanosecond resolution realtime clock (equivalent of CLOCK_REALTIME); o nanosecond resolution monotonic clock (equivalent of CLOCK_MONOTONIC). In addition to this, this option provides unified interface to get bintime (equivalent of using SO_BINTIME), except it also supported with IPv6 where SO_BINTIME has never been supported. The long term plan is to depreciate SO_BINTIME and move everything to using SO_TS_CLOCK. Idea for this enhancement has been briefly discussed on the Net session during dev summit in Ottawa last June and the general input was positive. This change is believed to benefit network benchmarks/profiling as well as other scenarios where precise time of arrival measurement is necessary. There are two regression test cases as part of this commit: one extends unix domain test code (unix_cmsg) to test new SCM_XXX types and another one implementis totally new test case which exchanges UDP packets between two processes using both conventional methods (i.e. calling clock_gettime(2) before recv(2) and after send(2)), as well as using setsockopt()+recv() in receive path. The resulting delays are checked for sanity for all supported clock types. Reviewed by: adrian, gnn Differential Revision: https://reviews.freebsd.org/D9171 Notes: svn path=/head/; revision=312296
