Util-linux 2.30 Release Notes
=============================

The libblkid library has been improved for hybrid CDROM/DVD media by extracting
the LABEL and UUID values from the UDF header, rather than the ISO9660 header.
This change makes hybrid CDROM/DVD media created on other operating systems more
compatible in Linux user-space. Unfortunately, this change may introduce a
regression for (unusual) hybrid CDROM/DVDs where the ISO and UDF headers use a
different LABEL.

The deprecated command tailf has been removed. Use ""tail -f"" from coreutils.

blkzone -- NEW COMMAND to run zone commands on block devices that support Zoned
Block Commands (ZBC) or Zoned-device ATA Commands (ZAC). The currently
supported functionality is 'report' and 'reset'.
[thanks to Shaun Tancheff (Seagate), Damien Le Moal (WD)]

fincore -- NEW COMMAND to count pages of file contents in core (memory).
[thanks to Masatake YAMATO (Red Hat)]

lsmem -- NEW COMMAND to list the ranges of available memory with their online
status (originally implemented in Perl for s390-tools). [thanks to Clemens von Mann
and Heiko Carstens (IBM)]

chmem -- NEW COMMAND to set memory online/offline status [thanks to Heiko
Carstens (IBM)]

Removed Alpha and dead code from hwclock's --directisa option.

The command fallocate supports an ""insert range"" operation now.

The command ""column -t|--table"" has been modified to use libsmartcols. It now
provides nearly all of that library's functionality from the command line. For
example: printing a table header, reordering columns, aligning columns
to the right, printing tree-like output, wrapping lines in cells, truncating
text in cells, etc.
The libmount library now provides an API to generate exit codes and error/warning
messages compatible with mount(8).


Security issues
---------------

hwclock - no longer makes any internal permission checks. The System
  Administrator must set proper permissions to control user access to
  the RTC. It is NOT recommended to use set-user-ID.

CVE-2016-2779 - This security issue is NOT FIXED yet.  It is possible to
  disable the ioctl TIOCSTI by setsid() only.  Unfortunately, setsid()
  has well-defined use cases in su(1) and runuser(1) and any changes
  would introduce regressions.  It seems we need a better way -- ideally
  another ioctl to disable TIOCSTI without setsid() or in a userspace
  implemented pty container (planned as experimental su(1) feature).
