RHBA-2015:2160 - Bug Fix Advisory

Topic

Updated coreutils packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 7.

Description

The coreutils packages contain the GNU Core Utilities and represent a combination of the previously used GNU fileutils, sh-utils, and textutils packages.

The following enhancements are described in more detail in the Red Hat Enterprise Linux 7.2 Release Notes, linked to in the References section:

• The "tail --follow" command now works properly on files on Veritas Clustered file system (VXFS). (BZ#1109083)
• The "dd" command is now capable of showing transfer progress. (BZ#1147701)

Notably, the bugs fixed by this update include:

• The "-Z" option accepted by the cp, install, mkdir, mkfifo, and mknod utilities no longer requires an argument and instead restores the default SELinux context in Red Hat Enterprise Linux 7. However, the "--context" option, which is the long format version of "-Z", optionally accepts an argument. The differences in behavior of the two options sometimes confused users. The man pages documenting "-Z" and "--context" have been modified to describe the options separately and clarify their behavior. (BZ#1084471)
• Previously, if multiple NFS mount points shared a superblock, the "df" utility only listed one of them unless the "-a" option was used. This update improves the filtering methods of "df", and the utility now properly displays all NFS mount points on the same superblock. (BZ#1100026, BZ#1197463)
• When no user was specified, the "id -G" and "groups" commands printed the default group ID listed in the password database. Consequently, the IDs were in certain cases ineffective or incorrect. With this update, the commands have been enhanced to print only proper IDs, thus showing correct information about the groups. (BZ#1115430)
• Previously, the colorls.sh and colorls.csh scripts sometimes called different utilities than expected. Running the scripts in some situations also resulted in the session becoming unresponsive. This update modifies colorls.sh and colorls.csh to always execute the utilities by running their full paths instead of relative paths. As a result, the scripts now execute the expected utilities, and the session no longer hangs. (BZ#1222223)
• The "du" utility sometimes showed misleading messages when displaying information about environments using chroot operations and bind mounts. The error messages warned the user that the file system is corrupted even though this was not true. With this update, the error message no longer reports system corruption. Also, "du" no longer produces an error exit code unless necessary and instead exits with the status of 0. (BZ#1238191)

Users of coreutils are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
