X-Git-Tag: hostap_0_7_2~125
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=03bcb0af0d4209f41a8563c60ad6168ae70c53ff;p=thirdparty%2Fhostap.git

Fix wpa_auth_iface_iter() to skip BSSes without Authenticator

This could cause NULL pointer deference if multi-BSS configuration
was used with OKC in some cases.
