RHBA-2012:1518 - Bug Fix Advisory

Topic

Updated NetworkManager packages that fix three bugs and add an enhancement are
now available for Red Hat Enterprise Linux 6.

Description

NetworkManager is a system network service that manages network devices and
connections, attempting to keep active network connectivity when available. It
manages Ethernet, wireless, mobile broadband (WWAN), and PPPoE (Point-to-Point
Protocol over Ethernet) devices, and provides VPN integration with a variety of
different VPN services.

This update fixes the following bugs:

• Due to a bug reading and writing network configuration files, network

connections using the LEAP authentication method could not be made available to
all users. A patch has been provided to address this issue and the network
configuration files now allow LEAP as expected. (BZ#864828)

• Previously, NetworkManager did not allow selecting the WPA protocol version

for connection. Certain enterprise WLAN networks using Cisco equipment do not
allow roaming between WPA and WPA2 Virtual Access Points (VAP) provided by the
same physical access point, requiring the use of a specific WPA protocol version
to prevent disconnections. This update adds a WPA protocol combo box to the
NetworkManager user interface (UI), thus allowing a specific WPA protocol
version to be used when necessary and preventing this bug. (BZ#864829)

• When a connection was locked to a specific WPA protocol version (either v1 or

v2/RSN) via either the GConf system or settings in the
/etc/sysconfig/network-scripts/ configuration files, the NetworkManager UI
overwrote that preference when the connection was edited and saved. This bug has
been fixed and such WPA preferences are now preserved in the described scenario.
(BZ#864830)

This update adds the following enhancement:

• Support for Opportunistic Key Caching (OKC), also known as Proactive Key

Caching (PKC), has been added to NetworkManager for all WPA-Enterprise
configurations. (BZ#864831)

Users of NetworkManager are advised to upgrade to these updated packages, which
fix these bugs and add this enhancement.
