Jens Schweikhardt 25c54b848e Reference correct section for free(3). 2022-09-17 13:12:44 +02:00
Kirk McKusick 90e29718cf Clarify when GEOM utilities exit with success or failure.
Historically, GEOM utilities (gpart(8), gstripe(8), gmirror(8),
etc) used the gctl_error() routine to report errors. If they called
gctl_error() they would exit with EXIT_FAILURE, otherwise they would
return with EXIT_SUCCESS. If they used gctl_error() to output an
informational message, for example when run with the -v (verbose)
option, they would mistakenly exit with EXIT_FAILURE. A further
limitation of the gctl_error() function was that it could only be
called once. Messages from any additional calls to gctl_error()
would be silently discarded.

To resolve these problems a new function, gctl_msg() has been added.
It can be called multiple times to output multiple messages. It
also has an additional errno argument which should be zero if it is
an informational message or an errno value (EINVAL, EBUSY, etc) if
it is an error. When done the gctl_post_messages() function should
be called to indicate that all messages have been posted. If any
of the messages had a non-zero errno, the utility will EXIT_FAILURE.
If only informational messages (with zero errno) were posted, the
utility will EXIT_SUCCESS.

Alexander Motin 7f16b501e2 GEOM: Introduce partial confxml API
Traditionally the GEOM's primary channel of information from kernel to
user-space was confxml, fetched by libgeom through kern.geom.confxml
sysctl.  It is convenient and informative, representing full state of
GEOM in a single XML document.  But problems start to arise on systems
with hundreds of disks, where the full confxml size reaches many
megabytes, taking significant time to first write it and then parse.

This patch introduces alternative solution, allowing to fetch much
smaller XML document, subset of the full confxml, limited to 64KB and
representing only one specified geom and optionally its parents.  It
uses existing GEOM control interface, extended with new "getxml" verb.
In case of any error, such as the buffer overflow, it just transparently
falls back to traditional full confxml.  This patch uses the new API in
user-space GEOM tools where it is possible.

Make gctl_add_param() API public, allowing more precise control over
parameter flags.  Previously it was impossible to properly declare
write-only ASCII parameters, used for result reporting, they were
declared as read-write binary instead, that was not nice.

Alan Somers ab63da3564 Speed up geom_stats_resync in the presence of many devices
The old code had a O(n) loop, where n is the size of /dev/devstat.
Multiply that by another O(n) loop in devstat_mmap for a total of
O(n^2).

This change adds DIOCGMEDIASIZE support to /dev/devstat so userland can
quickly determine the right amount of memory to map, eliminating the
O(n) loop in userland.

This change decreases the time to run "gstat -bI0.001" with 16,384 md
devices from 29.7s to 4.2s.

Also, fix a memory leak first reported as PR 203097.

Pedro F. Giffuni 5e53a4f90f lib: further adoption of SPDX licensing ID tags.
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.

Enji Cooper e976502216 libgeom(3): note that stdio.h is required when referencing gctl_dump(3)
gctl_dump(3) is only exposed when stdio.h is #include'd first, per its
addition in r112510. The reasoning noted for the conditional "exposure"
of the function was to "limit #include pollution".

This addresses an issue I found with the documentation when looking at
bug 218809, which in turn addresses a -Wimplicit-function-declaration
compiler warning in `tools/regression/geom_gpt/test.c` (it uses
gctl_dump(3)).
