RHBA-2015:1251 - Bug Fix Advisory

Topic

Updated iputils packages that fix several bugs are now available for Red Hat Enterprise Linux 6.

Description

The iputils packages contain basic utilities for monitoring a network, including ping.

This update fixes the following bugs:

• The arping command previously returned incorrect exit codes in some cases due to incorrect time related logic and exit-handling conditions in the code. With this update, the aforementioned problems have been fixed, and arping again returns correct values. (BZ#829998)
• Due to incorrect code that handles the number of return path hops, the tracepath utility displayed an incorrect number of "back" hops. This update fixes the logic, and the number of displayed back hops is now accurate. (BZ#1099426)
• When domain name translation was forced to be carried out over the IPv6 protocol, the output of the "ping" command was incorrect as it displayed an incorrect IP address received from the internal library. The underlying logic has been modified to use the gethostbyname2() function instead of gethostbyname(), and domain name to IP address translation now works correctly. (BZ#1113082)
• Due to invalid logic present in the code, an erroneous warning message

could be returned under certain circumstances:

WARNING: kernel is not very fresh, upgrade is recommended.

This update removes the code responsible for returning this erroneous
warning message, thus fixing the bug. (BZ#1149574)

Users of iputils are advised to upgrade to these updated packages, which fix these bugs.
