8.70. iotop
An updated iotop package that fixes several bugs is now available for Red Hat Enterprise Linux 6.
The iotop package provides a program with a UI similar to the "top" utility. The program watches input-output (I/O) usage information output by the Linux kernel and displays a table of current I/O usage by processes on the system.
Bug Fixes
- BZ#746240, BZ#908149
- Previously, the iotop utility terminated unexpectedly when it was run by a non-root user. This was because a recently-applied patch in CVE-2011-2494 made I/O statistics from the taskstats kernel subsystem accessible only to root users, and iotop did not anticipate that its "taskstats" call could fail when run by a non-root user. This update adds permission checks to iotop, and when the user does not have the necessary permissions, iotop exits with an explanation that root privileges are now required.
- BZ#826875
- Previously, the iotop utility did not handle platform strings correctly. Consequently, the iotop command could not show the I/O scheduling class and its priority ("PRIO") column on 64-bit PowerPC systems properly. With this update, the bug has been fixed so that the iotop command now shows the "PRIO" column on 64-bit PowerPC systems as expected.
- BZ#849559
- When an invalid locale was set, the iotop utility failed to start with the following traceback error:locale.Error: unsupported locale settingWith this update, the underlying source code has been modified. As a result, when an invalid locale is set, the default locale is used instead and a warning about this change is returned.
Users of iotop are advised to upgrade to this updated package, which fixes these bugs.
