Remove bt(4) driver

2018-10-22T02:34:59+00:00

The buslogic scsi driver has been tagged as gone in 12 for some time
now. Remove it. The nycbug dmesg database shows only one sighting in 6
for this driver. It was very popular in the early days of the project,
but that popularity seems to have died by 2004 when the nycbug
database started up.

Relnotes: yes

Tag the current round of deprecated drivers.

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.

sys/dev: Replace zero with NULL for pointers.

2017-02-20T03:43:12+00:00

Makes things easier to read, plus architectures may set NULL to something
different than zero.

Remove dead mentions of CAM target mode APIs from drivers.

This makes grepping kernel for target mode implementation much easier.

machines, only a few 486 machines that used it, and those haven't had
enough memory to run FreeBSD for quite some time (often limited to
16MB).

Not to be confused with the Machine Check Architecture, which is still
very much alive and used (and untouched by this commit).

Always null-terminate ccb_pathinq.(sim_vid|hba_vid|dev_name)

2017-01-04T20:26:42+00:00

The sim_vid, hba_vid, and dev_name fields of struct ccb_pathinq are
fixed-length strings. AFAICT the only place they're read is in
sbin/camcontrol/camcontrol.c, which assumes they'll be null-terminated.
However, the kernel doesn't null-terminate them. A bunch of copy-pasted code
uses strncpy to write them, and doesn't guarantee null-termination. For at
least 4 drivers (mpr, mps, ciss, and hyperv), the hba_vid field actually
overflows. You can see the result by doing "camcontrol negotiate da0 -v".

This change null-terminates those fields everywhere they're set in the
kernel. It also shortens a few strings to ensure they'll fit within the
16-character field.
