RHBA-2012:1518 - NetworkManager bug fix and enhancement update

Synopsis

NetworkManager bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

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.

Solution

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