7.273. wpa_supplicant

Updated wpa_supplicant packages that fix multiple bugs and add one enhancement are now available for Red Hat Enterprise Linux 6.
The wpa_supplicant packages contain a WPA (Wi-Fi Protected Access) Supplicant utility for Linux, BSD, and Windows with support for WPA and WPA2 (IEEE 802.11i/RSN). The supplicant is an IEEE 802.1X/WPA component that is used in client workstations. It implements key negotiation with a WPA Authenticator and it controls the roaming and IEEE 802.11 authentication and association of the WLAN driver.

Bug Fixes

When roaming from one Access Point (AP) to another and the connection was disrupted, NetworkManager did not always automatically reconnect. This update includes a number of backported upstream patches to improve Proactive Key Caching (PKC), also known as Opportunistic Key Caching (OKC). As a result, WPA connections now roam more reliably.
Previously, the supplicant would attempt to roam to slightly stronger access points, increasing the chance of a disconnection. This bug has been fixed and the supplicant now only attempts to roam to a stronger access point when the current signal is significantly degraded.


The "wpa_gui" program was removed from "wpa_supplicant" in the 6.0 release as per BZ#553349, however, the man page was still being installed. This upgrade removes the man page.
All users of wpa_supplicant are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.
