RHBA-2012:0978 - wpa_supplicant bug fix update


Synopsis

wpa_supplicant bug fix update

Type/Severity

Bug Fix Advisory

Topic

An updated wpa_supplicant package that fixes a bug is now available for Red Hat Enterprise Linux 6.

Description

The wpa_supplicant package contains 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 updated wpa_supplicant package fixes the following bug:

  • Due to an error in the wpa_supplicant code, Wi-Fi signal levels for some wireless devices reported by the Linux kernel's nl80211 API were not handled correctly. Consequently, the NetworkManager applet did not indicate the signal strength for unconnected networks. With this update, the code has been corrected and the NetworkManager applet now indicates signal strength for drivers using the nl80211 API as expected. (BZ#752032)

All users of wpa_supplicant are advised to upgrade to this updated package, which fixes this bug.
