spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD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

Use kdb_thr_from_pid() in db_lookup_thread().

2021-01-01T00:01:27+00:00

The code is identical, so this should be a no-op.

Don't check P_INMEM in kdb_thr_*().

2021-01-01T00:01:12+00:00

Not all debugger operations that enumerate threads require thread
stacks to be resident in memory to be useful.  Instead, push P_INMEM
checks (if needed) into callers.

proc: eliminate the zombproc list

2019-08-28T16:18:23+00:00

It is not needed by anything in the kernel and it slightly drives up contention
on both proctree and allproc locks.

ddb: Enable 'thread
'

2018-10-20T20:45:49+00:00

Currently, the 'thread' command (to switch the debugger to another thread)
only accepts decimal-encoded tids.  Use the same parsing logic as 'show
thread ' to accept hex-encoded thread pointers in addition to
decimal-encoded tids.

Document the 'thread' command in ddb.4 and expand the 'show thread'
documentation to cover the tid usage.

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

2017-11-27T15:14:46+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.

ddb: finish converting boolean values.

2015-05-21T15:16:18+00:00

The replacement started at r283088 was necessarily incomplete without
replacing boolean_t with bool.  This also involved cleaning some type
mismatches and ansifying old C function declarations.
