Topic

Updated wpa_supplicant packages that fix multiple bugs and add one enhancement
are now available for Red Hat Enterprise Linux 6.

Description

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.

This update fixes the following bugs:

  • 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. (BZ#813579)

  • 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. (BZ#837402)

This update also adds the following enhancement:

  • 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. (BZ#672976)

All users of wpa_supplicant 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.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
