spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD2023-07-25T15:13:49ZWarner Loshimp@FreeBSD.org2023-05-10T15:40:58Zurn:sha1:caa41f641755c935b036e17440a3b49329c904ed
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.

lib: further adoption of SPDX licensing ID tags.2017-11-26T02:00:33ZPedro F. Giffunipfg@FreeBSD.org2017-11-26T02:00:33Zurn:sha1:5e53a4f90f82c4345f277dd87cc9292f26e04a29
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified 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.
libproc: Add support for some proc_attach() flags.2016-12-06T04:22:38ZMark Johnstonmarkj@FreeBSD.org2016-12-06T04:22:38Zurn:sha1:b043b5dc6bf70af9d188fc37d201bb35dab8feec
This change adds some handling for the equivalent of Solaris' PGRAB_*
flags. In particular, support for PGRAB_RDONLY is needed to avoid a
nasty deadlock: dtrace(1) may otherwise stop the master process for its
pseudo-terminal and end up blocking while writing to standard output.
libproc: Match prefixes when looking up mapped object by name.2016-12-06T04:20:32ZMark Johnstonmarkj@FreeBSD.org2016-12-06T04:20:32Zurn:sha1:d42df2a44793413692a006e46faad87ec7b9e34f
When looking up an object by name, allow prefix matches if no direct match
is found. This allows one to, for example, match libc entry probes with:
# dtrace -n 'pid$target:libc.so::entry' -c ./foo
instead of requiring "libc.so.7" or a glob.
Also remove proc_obj2map() as it currently just duplicates the
functionality of proc_name2map(). It's supposed to take a Solaris
link-map ID as a paramter, but support for this isn't implemented and
isn't required to support DTrace's pid provider.
libproc: Cache ELF handles for loaded objects.2016-12-06T04:19:08ZMark Johnstonmarkj@FreeBSD.org2016-12-06T04:19:08Zurn:sha1:07a9c2e65d5f2f21cc9783e33dd94a5ce8cc592d
libproc previously created a new handle for each symbol lookup, which
gives rather egregious performance for DTrace's ustack() action. With
this change libproc will cache the libelf descriptor upon access, making
lookups much faster in the common case.
libproc: Make proc_getpid() an accessor for struct proc_handle.2016-12-06T04:14:20ZMark Johnstonmarkj@FreeBSD.org2016-12-06T04:14:20Zurn:sha1:b1bb30e5c5786253ff0316a29e0929dd1168effa
This allows librtld_db to fetch the PID from a handle without calling into
libproc. Together with r303531, this means that librtld_db no longer
references symbols from libproc.
Fix style bugs and remove trailing whitespace in libproc and librtld_db.2016-12-06T04:13:02ZMark Johnstonmarkj@FreeBSD.org2016-12-06T04:13:02Zurn:sha1:fcf9fc109edfef9d3bbd6f03bd796ac728cb9258

libproc: Add proc_getmodel().2016-07-30T03:09:23ZMark Johnstonmarkj@FreeBSD.org2016-07-30T03:09:23Zurn:sha1:4808a67805fe7287d8054934d978cd1076302689
This is used by libdtrace to determine the data model of target processes.
This allows for the creation of pid provider probes in 32-bit processes on
amd64.
