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
