An updated iproute package that fixes various bugs is now available for Red Hat Enterprise Linux 5.
The iproute package contains networking utilities (ip and rtmon, for example) which are designed to use the advanced networking capabilities of the Linux kernel.
Prior to this update, the ARP daemon, "arpd", had several undocumented options, including, "-?", "-B", "-R", "-b", "-h", "-k", and "-l". Consequently users issuing the command "arp --help" to see the usage message, or consulting the man page, did not see an explanation for all the options. With this update the help function's usage message and the man page have been corrected.
Prior to this update, the "lnstat" usage message and man page contained spelling mistakes for the "-dump" and "-key" options. With this update these errors have been corrected.
Prior to this update, the "ss" usage message and man page erroneously included an unsupported option ("-query") and omitted three supported options ("-diag", "-D", and "-socket"). With this update these errors and omissions have been corrected.
Prior to this update, the "ss -4n" command did not distinguish between the "inet" and "inet6" domain when loading the tcp_diag module. Consequently IPv6 information was output in addition to the expected IPv4 information. With this update the code has been corrected and the command functions as expected.
All users of iproute are advised to upgrade to this updated package, which fixes these bugs.
