spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

2023-05-12T16:44:03+00:00

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

mpr/mps(4): Make device mapping some more robust.

2021-04-24T03:36:51+00:00

Allow new enclosure to replace previously existing one if there is
no completely unused table entry, same as it is done for devices.

If we can not process DPM due to corruption -- wipe it and restart
from scratch.  Otherwise I don't see a way to recover persistence if
something go wrong and there is no BIOS to recover it for us.

Together this solves a problem that appeared when 9300-8i firmware
update to 16.00.10.00 somehow switched its mapping mode from Device
Persistence to Enclosure/Slot without wiping the DPM table.  It made
HBA completely unusable, since overflowed and conflicting mapping
table was unable to map any of enclosures and so devices.

Also while there make some enclosure mapping errors more informative.

Uses of mallocarray(9).

The use of mallocarray(9) has rocketed the required swap to build FreeBSD.
This is likely caused by the allocation size attributes which put extra pressure
on the compiler.

Given that most of these checks are superfluous we have to choose better
where to use mallocarray(9). We still have more uses of mallocarray(9) but
hopefully this is enough to bring swap usage to a reasonable level.

dev: make some use of mallocarray(9).

2018-01-13T22:30:30+00:00

Focus on code where we are doing multiplications within malloc(9). None of
these is likely to overflow, however the change is still useful as some
static checkers can benefit from the allocation attributes we use for
mallocarray.

This initial sweep only covers malloc(9) calls with M_NOWAIT. No good
reason but I started doing the changes before r327796 and at that time it
was convenient to make sure the sorrounding code could handle NULL values.

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

2017-11-27T14:52:40+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.

commit it to make initiazation less chatty in the normal case, and more useful
and informative when real debugging is turned on.
