Statement: This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 4 and 5 as they did not backport the upstream commit d03032af that introduced this issue. Future kernel updates in Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG may address this flaw. This issue has been addressed in following products: MRG for RHEL-5 Via RHSA-2011:0330 https://rhn.redhat.com/errata/RHSA-2011-0330.html This issue has been addressed in following products: Red Hat Enterprise Linux 6 Via RHSA-2011:0421 https://rhn.redhat.com/errata/RHSA-2011-0421.html State: DISCONNECTED -> SCANNING Starting AP scan for wildcard SSID Scan requested (ret=0) - scan timeout 5 seconds EAPOL: disable timer tick EAPOL: Supplicant port status: Unauthorized Scan timeout - try to get results Failed to get scan results Failed to get scan results - try scanning again Setting scan request: 1 sec 0 usec Starting AP scan for wildcard SSID Scan requested (ret=-1) - scan timeout 5 seconds Failed to initiate AP scan.

Enable the port when disabling countermeasures, and disable it on enabling countermeasures. This bug causes the response of the system to certain attacks to be ineffective. It also prevents wpa_supplicant from getting scan results, as wpa_supplicant disables countermeasures on startup - preventing the hardware from scanning. wpa_supplicant works with ap_mode=2 despite this bug because the commit handler re-enables the port. The log tends to look like: State: DISCONNECTED -> SCANNING Starting AP scan for wildcard SSID Scan requested (ret=0) - scan timeout 5 seconds EAPOL: disable timer tick EAPOL: Supplicant port status: Unauthorized Scan timeout - try to get results Failed to get scan results Failed to get scan results - try scanning again Setting scan request: 1 sec 0 usec Starting AP scan for wildcard SSID Scan requested (ret=-1) - scan timeout 5 seconds Failed to initiate AP scan.
