RHBA-2014:0535 - Bug Fix Advisory

Topic

Updated netlabel_tools packages that fix three bugs are now available for Red
Hat Enterprise Linux 6.

Description

NetLabel is a kernel subsystem which implements explicit packet labeling
protocols such as CIPSO. Packet labeling is used in secure networks to mark
packets with the security attributes of the data they contain. This package
provides the necessary user space tools to query and configure the kernel
subsystem.

This update fixes the following bugs:

• Prior to this update, netlabelctl, the NetLabel management tool, incorrectly

handled multi-part netlink messages that limited the number of static labels
displayed. Consequently, running the "netlabelctl unlbl list -p" command did not
provide the correct output when a large number of static labels were configured.
This bug has been fixed, and netlabelctl now works correctly and lists all the
configured static labels as expected. (BZ#918763)

• Previously, netlabelctl did not allocate enough buffer space for large

configuration messages from the kernel. In addition, netlabelctl could not
adjust the buffer size in the cases where the buffer was not large enough. As a
consequence, a large number of CIPSO level and category translations could not
be used. With this update, the default message buffer has been increased, and
the buffer is now increased dynamically as necessary. As a result, a large
number of CIPSO level and category translations can be used as expected in this
scenario. (BZ#1000177)

• Prior to this update, the file with the licence text was not included in the

binary packages. This update adds the license text in the packages. (BZ#1098082)

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

Solution

Before applying this update, make sure all previously released errata relevant
to your system have been applied.
