* 'PR/column-input-separator-alias' of https://github.com/karelzak/util-linux-work:
column: add --input-separator as an alias for --separator
|
|
This change adds --input-separator as an alias for the existing
--separator option, providing symmetry with --output-separator.
The new alias is documented in:
- command-line help text
- man page
- bash completion

The option --buffer-size already infers that its the optional argument
is a size value. In addition to that, when the option is completed the
user will have to delete the word 'size' from the command line and type
the desired value, which is not an ideal user experience.

* 'fix/rename_annotation_opt_to_annotate' of https://github.com/cgoesche/util-linux-fork:
man-common: rename annotation.adoc to annotate.adoc
swapon: use ANNOTATE_OPTION as enum name for --annotate
swapon: rename the new --annotation option to --annotate
swapon: (usage) make the help text fit within 80 columns again
|
|
The form --annotation gave the impression that after the subsequent
"=" comes the text that each column name should be annotated with.
Furthermore, the other two options with optional arguments (--show
and --discard) are in the imperative, so follow that style and use
--annotate instead.
(In the bargain, this allows aligning the descriptions in the help
text perfectly again.)
Also, improve the description of --annotate in the man page somewhat.

The bits command was added in commit 6e1301d59 (text-utils: add bits
command) but the bash-completion file was not added to the autotools
Makemodule.am, causing it to be missing from release tarballs.
This resulted in meson build failures when using the tarball with
bash-completion installed, as meson.build references the file but
it doesn't exist in the tarball.

The function "_enosys_module" referenced by the completion setting on
the last line of "bash-completion/enosys" is not defined in the
current master. As reported in Ref. [1], this causes the following
error on an attempt at argument completion for the "enosys" command:
bash: _enosys_module: command not found
[1] https://www.reddit.com/r/Fedora/comments/1llmu0w/comment/n00y98k/
Also, the function "_waitpid_module" defined in
"bash-completion/enosys" overwrites another completion function of the
same name defined in "bash-completion/waitpid". This patch renames
the function in "bash-completion/enosys" to the correct one,
"_enosys_module".

https://github.com/akinomyoga/util-linux
* 'bash-completion-command-lsblk' of https://github.com/akinomyoga/util-linux:
bash-completion: use "command ls" instead of "\ls"
bash-completion: prefix "command" to other external commands
bash-completion: prefer "builtin cd" to "cd" to avoid aliases
bash-completion: prefer "command lsblk" to "lsblk" to avoid aliases
|
|
The backslash quoting can be used to bypass aliases, but it cannot be
used to bypass shell functions for interactive uses defined by the
users. We can use "command ls" instead to bypass both aliases and
shell functions.
|
|
|
|
The command "cd" is also often aliased, so we should use "builtin cd"
to make sure to use the built-in version of "cd".
|
|
The user may define an alias lsblk to specify the default formatting,
such as -T, which would conflict with lsblk -r used in the Bash
completion settings. In the Bash completion settings, to prevent the
calls of lsblk -r ... from being replaced with lsblk -T -r ... and
failing, lsblk should be called using command lsblk.
|

When cachestat() is not available, mmap() and fincore() are used to get
cache statistics.
This fallback returns less data than cachestat, and potentially hides
read errors by reporting that the file is all mapped in memory:
$ fincore /usr/bin/java
fincore: failed to do cachestat: /usr/bin/java: Operation not permitted
RES PAGES SIZE FILE
208K 13 198,1K /usr/bin/java
$ echo $?
0
$ sudo fincore /usr/bin/java
RES PAGES SIZE FILE
0B 0 198,1K /usr/bin/java
Add a --cachestat argument which forces cachestat usage and fails if
it's not available:
$ fincore -C /usr/bin/java
fincore: failed to do cachestat: /usr/bin/java: Operation not permitted
$ echo $?
1
Also, on huge files the fallback is very slow and memory consuming,
so this flag can be user to avoid doing it by mistake.
|
|
Add a --recursive flag to fincore which allows to recursively scan
directories.

Most other util-linux tools that accept the option argument "auto"
additionally accept "always" and "never", not "enable" / "disable".
So, make option --cpu-stat accept those standard words (besides the
deviant ones), and adjust the documentation to use the standard words.
Furthermore, make --cpu-stat accept also "on", "off", "yes", "no",
"1", and "0", to allow the user to use shorter words. The per-CPU
stats can now be suppressed with a succinct: `irqtop -c0`.

Now, it is possible to exclude files by their names, but it does not
allow for ignoring entire subtrees of the scanned hierarchy. The new
option only applies to directory names and forces the file-tree-walk
to skip the directory and all of its subdirectories.
This is based on FTW_SKIP_SUBTREE, which was originally only available
in glibc (since 2004). Therefore, the code is #ifdef-ed to make it
portable to other libc versions.

Add a new text utility to convert bit masks in various formats.
This can be handy to avoid parsing affinity masks in one's head and/or
to interact with the kernel in a more human friendly way. It is
a rewrite in C of the bits command from my linux-tools python package so
that it can be more widely available.
Here is an example:
~# cat /sys/kernel/debug/tracing/tracing_cpumask
ffffffff,ffffffff,ffffffff,ffffffff
~# bits -l ,$(cat /sys/kernel/debug/tracing/tracing_cpumask)
0-128
~# bits -g 58,59,120,123
9000000,00000000,0c000000,00000000
~# bits -g 58,59,120,123 > /sys/kernel/debug/tracing/tracing_cpumask
~# echo 1 > /sys/kernel/debug/tracing/tracing_on
Add man page and basic tests.

Why do we need this? It can be difficult for end-users to discard
unpartitioned areas using blkdiscard, as it requires using fdisk to
obtain a list of free areas and then using blkdiscard with the correct
--offset and --length options. It is less risky for end-users to use
(s)fdisk, as they have a better understanding of the disk layout.

look(1) opens /usr/share/dict/words as dictionary by default. Doing TAB
completion for look(1) without the dictionary installed will result in
popups like
$ look look: /usr/share/dict/words: No such file or directory
messing up the terminal.
As /usr/share/dict/words is not shipped by quite a few distros nowadays
and it should not be listed as a hard dependency of util-linux, we make
sure the dictionary exists before calling look(1) when doing completion,
avoiding these error messages.
When completing the word without anything specified on the command line,
alphabets and numbers instead of all words are listed as a hint, for
better interacting experience.

landlock [0] is a Linux stackable LSM that can be used by unprivileged
processes to build a sandbox around them.
With support for landlock in setpriv users can easily construct a
sandbox on-the-fly when executing programs.

Building util-linux logs a warning on Gentoo:
```
* Problems with installed bash completions were found:
*
* lastb: incorrect name, no completions for 'lastb' command defined.
*
* For more details on installing bash-completions, please see:
* https://wiki.gentoo.org/wiki/Bash/Installing_completion_files
```
A bash-completion file is usually composed of two parts:
- a function that knows how to produce completions
- a specification of which command should be completed
In cases where multiple commands have the same options, e.g. commands
that are symlinked to each other, it is common to symlink the completion
files as well. This shares the first part. But the second part cannot be
shared, it must be implemented twice by specifying two different
commands to be completed.
"lastb" had a symlinked completion, but when the completion system
processes /usr/share/bash-completion/completions/lastb, it would only
define a completion for "last".
Define both completions in one file, so that sourcing it works
regardless of command used.

This program allows running a command in a new process group and
optionally makes the new process group the foreground process group
of the ctty.
This is useful when running programs through wrappers programs (think
bubblewrap, ...) and wanting to make sure that SIGINT is only sent to
the innermost process. This is possible by putting the innermost process
in a new process group and making that process group the foreground process
group of the controlling terminal.
By adding a separate utility to util-linux, we can apply this to any
program even if the program itself doesn't implement this functionality.

This is mostly for testing purpose or performance tuning. The new
option allows generate multiple UUIDs using the enhanced capability of
the libuuid to cache time-based UUIDs.

This commit adds support for the -c or --join-cgroup option in nsenter, allowing a new process to join the cgroup of target process.
Example:
Setup the target process:
$ podman run --rm -d docker.io/golang sleep 10000
51a89deb6baf6d
$ podman inspect --format '{{ .State.Pid }}' 51a89deb6baf6d6
216054
Enter the cgroup namespace of target process without option -c:
$ sudo ./nsenter -C -U -t 216054 sh -c "cat /proc/self/cgroup"
0::/../../../../session-899.scope
Enter the cgroup namespace of target process with option -c:
$ sudo ./nsenter -c -C -U -t 216054 sh -c "cat /proc/self/cgroup"
0::/

* 'nsenter-add-parent-ns-option' of https://github.com/igo95862/util-linux:
Add `--user-parent` option to nsenter
|
|
When this option is used nsenter will fetch the parent user
namespace from any namespace file descriptors available.
It can be combined with existing `--user` option in which case
the parent user namespace will be fetched from the user namespace
and replace it.
The usecase of this option is when a user namespace that owns
the other type namespaces we want to switch to is not actually
bound to any process. Without using ioctl it is impossible to
acquire namespace file descriptor. For example, bubblewrap
`bwrap` command creates unbinded user namespace when `--dev`
option is used.

So replace it with an explicit "follow" argument that provides the new

This commit adds support for the -e or --env option in nsenter, allowing a new process to inherit the environment va
If the option is not given, the environment variables will stay the same as in the current namespace.
Example:
Setup the namespace:
$ docker run -d -e PROJECT='util linux' --rm alpine sleep 10000
cb0b69aa7aec
$ docker inspect --format '{{ .State.Pid }}' cb0b69aa7aec

Enter the namespace:
$ nsenter --all -t 470012 --env env
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
HOSTNAME=cb0b69aa7aec
PROJECT=util linux

Especially it allows to wait for process that are not children of the

In contrast to wait(1P) it does not allow to retrieve the processes exit
