script (lib/pty-session.c)
|
|
--------------------------
|
|
- (!) add #ifdefs and optional code for non-signalfd() systems
|
|
|
|
rev
|
|
---
|
|
- support huge input lines (for example read input by small fixed buffer
|
|
rather than try allocate all buffer for a whole line)
|
|
see: https://github.com/karelzak/util-linux/issues/972
|
|
|
|
col
|
|
---
|
|
- use unsigned sizes for columns and lines
|
|
- check for limits to avoid segfaults
|
|
- make it more robust
|
|
https://github.com/karelzak/util-linux/issues/749

|
cal
|
|
---
|
|
- support another --reforms, see for example freebsd version
|
|
https://github.com/freebsd/freebsd/blob/master/usr.bin/ncal/ncal.c#L72
|
|
|
|
lscpu
|
|
-----
|
|
- read cpuid and uname information from file if --sysroot is specified, then
|
|
we can prepare regression tests completely independent on hw and architecture.
|
|
|
|
lsblk
|
|
-----
|
|
- currently it does not show mountpoint for all devices in btrfs RAID. It's because
|
|
/proc/#/mountinfo contains reference to the one device only. Maybe we can add some
|
|
btrfs specific code to provide a better output for FS based stacks. Not sure.

nsenter(1)
|
|
----------
|
|
- read the default UID and GID from the target process.
|
|
http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/9553/focus=9585
|
|
|
|
hwclock
|
|
------
|
|
- use /var/lib/hwclock/drift to store hw-clock drift numbers.
|
|
- use /etc/adjtime as read-only for UTC/LOCAL information only
|
|
- the /var/lib/hwclock/drift should be implemented backwardly compatible,
|
|
it means use the file only if exists, otherwise follow /etc/adjtime
|
|
|
|
bash completion
|
|
---------------
|
|
- Optional argument handling requires user to press backspace to get
|
|
argument completion.
|
|
- Comma separated value, e.g., --output 'value1,value2', are not
|
|
completed for users.
|
|
|
|
libmount (mount/umount)
|
|
-----------------------
|
|
|
|
- add --onlyonce to force mount(8) to check if mountpoint is already used. Now
|
|
"already mounted" detection is used for --all only. The problem is if you
|
|
call "mount <mountpoint>" more than once for in fstab defined tmpfs (or network
|
|
filesystem etc.). In this case kernel does not return EBUSY, but a new instance
|
|
of the FS is created. https://github.com/karelzak/util-linux/issues/448
|
|
(... just idea, maybe wrong idea)
|
|
|
|
- support CAP_SYS_ADMIN; for mount(2) syscall the CAP_SYS_ADMIN is good
|
|
enough. Unfortunately, mount(8) does more things like check for filesystem
|
|
type (but it's usually done by udev, so root perms are unnecessary), create
|
|
loop devices, write to /run/mount/utab or /etc/mtab, etc.
|
|
|
|
It would be nice to improve libmount to check for CAP_SYS_ADMIN if suid not
|
|
set and allow to use it for simple tasks where no another operation is
|
|
necessary.
|
|
|
|
partx
|
|
-----
|
|
|
|
- support mapping by device-mapper if argv[0] is "kpartx" or --dm option is used.
|
|
|
|
|
|
getopt
|
|
------
|
|
It would be great if getopt could optionally ignore unknown options.
|
|
Currently, it outputs -- for every option it doesn't recognize but leaving the
|
|
option as it is could beneficial wrapper scripts which could then pass the
|
|
options they don't recognize as they are to the command they are wrapping.

docs
|
|
----
|
|
|
|
- (!) use something better than gtk-doc for libmount and libblkid (doxyden?)
|
|
|
|
- (!) add API documentation to libuuid
|
|
|
|
- (!) rewrite man pages to AsciiDoc and generate final man pages by Asciidoctor & Docbook
|
|
|
|
login-utils:
|
|
-----------
|
|
|
|
- consolidate newgrp(1)
|
|
* we have "su --group/--supp-group" to switch between groups, newgrp(1) in
|
|
util-linux and shadow-utils (and sg(1) alias in shadow-utils)
|
|
* the unique functionality provided by newgpr(1) is support for group
|
|
passwords [/etc/gshadow] -- do we really need this functionality?
|
|
* maybe we can mark group-passwords as deprecated, and replace sg(1) and
|
|
newgpr(1) with su(1) code. The another way is to ask for group password in
|
|
su --group too.
|
|
* note that shadow-utils newgpr(1) provides support for syslog and audit log.
|

libblkid
|
|
--------
|
|
|
|
- (!) add support for BitLocker Drive Encryption
|
|
https://github.com/karelzak/util-linux/issues/617
|
|
https://github.com/libyal/libbde/blob/master/documentation/BitLocker%20Drive%20Encryption%20(BDE)%20format.asciidoc
|
|
|
|
- (!) add support for dasd PT (used for example on s390)
|
|
|
|
libfdisk
|
|
--------
|
|
|
|
- add support for Apple Partition Map (see libblkid/src/partitions/mac.c)
|
|
http://en.wikipedia.org/wiki/Apple_Partition_Map
|
|
|
|
- add support for nested PT (e.g. hybrid MBR) to scripts
|
|
* add "nested-label:" block to sfdisk --dump
|
|
* add "nested-partitiontable" to sfdisk --JSON
|
|
* support nested labels parsing from dump
|
|
see https://github.com/karelzak/util-linux/issues/850
|
|
|
|
sfdisk
|
|
------
|
|
|
|
- don't backup PT in interactive mode before write to the devices is requested,
|
|
see https://github.com/karelzak/util-linux/issues/852
|
|
|
|
misc
|
|
----
|
|
|
|
- add mllockall() and SCHED_FIFO to hwclock,
|
|
see http://lkml.org/lkml/2008/10/12/132
|
|
|
|
|
|

|
|
exotic requests
|
|
---------------
|
|
|
|
- add SELinux security contexts support to the 'ipcs' utility
|
|
http://bugzilla.redhat.com/show_bug.cgi?id=225342
|
|
|
|
Would be great to list the current system IPC Objects with their respective
|
|
security labels (where allowed) with something like 'ipcs -Z' - following the
|
|
way other tools reports those.
