RHBA-2013:0225 - wpa_supplicant bug fix and enhancement update

Synopsis

wpa_supplicant bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

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.
