Make timespecadd(3) and friends public

2018-07-30T15:46:40Z

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.

libnetbsd: Make the function declaration of efopen() match the definition

In order to crossbuild FreeBSD on Mac/Linux I also need to build libnetbsd and FILE* is not equal to struct __sFILE on those platforms. Reviewed By: brooks, emaste Approved By: jhb (mentor) Differential Revision: https://reviews.freebsd.org/D13305

lib: further adoption of SPDX licensing ID tags.

2017-11-26T02:00:33Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

These are error-checked versions of memory allocation routines used by NetBSD code, and are being added to facilitate updates to makefs. Reviewed by: ngie Differential Revision: https://reviews.freebsd.org/D10291

Improve libnetbsd compatibility with NetBSD

2017-02-07T19:42:41Z

This change is being made to diff reduce/reduce duplication in contrib/netbsd-tests and to facilitate further porting of software from NetBSD Add the following headers: - sys/event.h: -- sys/types.h is required for kqueue on FreeBSD, but not NetBSD. - sys/types.h: -- NBBY is defined in sys/param.h on FreeBSD, not sys/types.h like on NetBSD. Pull in sys/param.h to have parity with NetBSD. - sys/wait.h: -- Define wrusage as __wrusage for parity with NetBSD typedef. - glob.h -- Define __gl_stat_t as "struct stat" for parity with NetBSD typedef. - pthread.h: -- Pull in pthread_np.h for _np functions defined separately on FreeBSD. Improve compatibility with NetBSD in the following headers: - sha1.h: -- define SHA1_CTX as SHA_CTX -- define SHA1Final as SHA1_Final - sha2.h: -- #include sha384 to pick up all of the SHA 384 bit macros and definitions. - util.h: -- Add sys/types.h to util.h to pollute the header for types used in flags_to_string and string_to_flags (u_long) as NetBSD doesn't require them for the functions.

libnetbsd: add pthread.h compat header

FreeBSD has pthread_np.h, which is used for consolidating all non-POSIX functions, but NetBSD doesn't have this concept. Make _np functions work seamlessly when ported from NetBSD to FreeBSD

libnetbsd: add sys/event.h compat header

This adds in necessary sys/types.h pollution for uintptr_t used in sys/event.h, which according to kqueue(2) on NetBSD isn't necessary.
