spdx: The BSD-2-Clause-NetBSD identifier is obsolete, drop -NetBSD

2023-05-12T16:44:04+00:00

The SPDX folks have obsoleted the BSD-2-Clause-NetBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

linux(4): make getcwd(2) return ERANGE instead of ENOMEM

2021-03-12T15:31:45+00:00

For native FreeBSD binaries, the return value from __getcwd(2)
doesn't really matter, as the libc wrapper takes over and returns
the proper errno.

cache: replace kern___getcwd with vn_getcwd

2020-02-01T20:38:38+00:00

The previous routine was resulting in extra data copies most notably in
linux_getcwd.

Linuxulator depends on a fundamental kernel settings such as SMP. Many

of them listed in opt_global.h which is not generated while building
modules outside of a kernel and such modules never match real cofigured
kernel.

So, we should prevent our users from building obviously defective modules.

Therefore, remove the root cause of the building of modules outside of a
kernel - the possibility of building modules with DEBUG or KTR flags.
And remove all of DEBUG printfs as it is incomplete and in threaded
programms not informative, also a half of system call does not have DEBUG
printf. For debuging Linux programms we have dtrace, ktr and ktrace ability.

sys/compat: further adoption of SPDX licensing ID tags.

2017-11-27T15:13:23+00:00

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified 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.
