RHBA-2013:0843 - Bug Fix Advisory

Topic

Updated arptables_jf packages that fix two bugs are now available for Red Hat
Enterprise Linux 6.

Description

The arptables_jf utility controls the arpfilter packet filtering code in the
Linux kernel.

This update fixes the following bugs:

• Prior to this update, both the "mangle-hw-s" and "mangle-hw-d" options

required the use of the "--arhln" option. However, even if the "--arhln" option
was specified on the command line, the "arptables" command did not recognize it.
As a consequence, it was not possible to use those two options successfully.
These updated packages fix this bug and the "--arhln" option can now be used
together with the mangle hardware options. (BZ#807315)

• When the "-x" command line option (exact values) was used along with the "-L"

(List rules) option, the arptables utility did not list rules but issued an
error message saying "-x" option is illegal with "-L". With this update, the
arptables utility now uses the "-x" option when listing rules. (BZ#963209)

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