Topic

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

Description

The wpa_supplicant packages contain an 802.1X Supplicant with support for WEP,
WPA, WPA2 (IEEE 802.11i / RSN), and various EAP authentication methods. It
implements key negotiation with a WPA Authenticator for client stations and
controls the roaming and IEEE 802.11 authentication/association of the WLAN
driver.

This update fixes the following bug:

  • 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#855255)

This update adds the following enhancement:

  • Support for Opportunistic Key Caching (OKC), also known as Proactive Key

Caching (PKC), has been added to WPA Supplicant to facilitate faster and less
error-prone roaming between access points in the same network. (BZ#855273)

Users of wpa_supplicant are advised to upgrade to these updated packages, which
fix this bug and add this enhancement.
