kdump: Add a facility to print numbers in decimal format always

2023-05-26T16:35:08+00:00

To help grepping kdump output by pid or tid it makes sence to print
some numbers in decimal format always. Eg, process or thread identifier
at least, as they already printed in decimal format.
Switch to print pid/tid arguments of some Linux signal related syscalls
in decimal format.

spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD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

ktrace: make ktr_tid a long not intptr_t (NFC)

2022-09-17T08:21:59+00:00

Long ago, ktr_tid was ktr_buffer which pointed to the buffer following
the header and was used internally in the kernel.  Use was removed in
efbbbf570d70b and it was repurposed as ktr_kid in c6854c347f4d8.  For
ABI reasons, it stayed an intptr_t rather than becoming an lwpid_t at
the time.  Since it doesn't hold a pointer any more (unless you have
a ktrace.out from 2005), change the type to long which is alwasy the
same size on all supported architectures.  Add a suggestion to change
the type to lwpid_t (__int32_t) on a future ABI break.

Remove most remaining references to ktr_buffer, retaing a comment in
kdump.c explaining why negative values are treated as 0.  While here,
accept that pid_t and lwpid_t are of type int and simplify casts in
printf.

This changed was motivated by CheriBSD where intptr_t is 16-bytes
in the pure-capability ABI.

ktrace: Increase precision of timestamps.

2022-07-16T09:46:12+00:00

Replace struct timeval in header with struct timespec.
To differentiate header formats, add a new KTR_VERSIONED flag
set in the header type field similar to the existing KTRDROP flag.

To make it easier to extend ktrace headers in the future,
extend the existing header with a version field (version 0 is
reserved for older records without KTR_VERSIONED) as well as
new fields holding the thread ID and CPU ID.
