Process Communication mechanism, and the addition of this control interface to

wpa_supplicant allows applications (like NetworkManager) to more reliably control the

supplicant.

Cisco Aironet 340/350 wireless cards were not able to successfully connect to 802.1x-

enabled wireless networks, often used in security sensitive organizations. During the

connection process at the 4-Way WPA handshake stage, sending encryption keys to the

driver would clear the wireless card firmware's authentication state. With this update, the

supplicant uses an alternate method of supplying encryption keys to the kernel driver,

allowing authentication state to be preserved in the Aironet firmware and 802.1x

connections to succeed.

Kernel drivers utilizing the new mac80211 wireless stack were sometimes unable to connect

to wireless networks, either failing to find the requested network, or prematurely ending

communication with the wireless access point during the connection process. Some drivers

were prone to reporting multiple disconnection events during the association process,

confusing the supplicant and causing long timeouts. T he supplicant also did not sufficiently

instruct the driver to disconnect when switching access points. This update fixes these

issues and, in conjunction with kernel driver updates, allow more wireless hardware to

successfully connect to wireless networks.

NetworkManager re-base

NetworkManager has been updated to version 0.7.0. T his update provides the following fixes

and enhancements:

NetworkManager would not display a LEAP password, even when the user selected the

"show password" option. This has been fixed through a rebase to NetworkManager 0.7.

During the beta phase, a version of NetworkManager was unable to automatically start

network interfaces for which "ONBOOT=no" was present in the ifcfg file. NetworkManager

now ignores this value unless "NM_RESPECT_ONBOOT=yes" is also present.

a NetworkManager plug-in was named for its upstream repository. This could cause end-

users to mistake the plug-in for an un-supported addition to Red Hat Enterprise Linux. T his

plug-in has been renamed to "ifcfg-rh".

with this update, support has been added to NetworkManager for wired 802.1x

authentication. However, after creating an 802.1x-enabled wired connection in the

NetworkManager connection editor, it may be necessary to log out, then log back in before

the connection can be used from the NetworkManager applet menu.

NetworkManager attempted to set a hostname, but only after X had already done so. T he

user could not then open new windows because the authority files had been set by X with a

different hostname. NetworkManager no longer sets hostnames.

an update for NetworkManager that was available in the beta phase would change the run

level enablement of the package during installation, and thus prevent NetworkManager from

starting. NetworkManager no longer changes run level enablements during installation.

on a system with more than one network adapter, network keys saved by the user while

connecting with one adapter would not be available when the user attempted to connect with

the other adapter. NetworkManager can now retrieve and use network keys saved for a

different adapter on the same network.

previously, NetworkManager would not always prompt the user for a new network key if the

protocol or key of a wireless network changed. Although NetworkManager would wait for a

new key, it would not always open a dialog box and allow the user to provide one.

NetworkManager will now open a dialog box when needed.

several bug fixes and enhancements for NetworkManager were available upstream.

NetworkManager has been rebased to version 0.7 to incorporate these improvements,
