Some legacy stations copy previously reserved RSN capability bits, including OCVC, in (Re)Association Request frames from the AP's RSNE but do not indicate MFP capability and/or do not send OCI in RSN handshakes. This is causing connection failures with such erroneous STAs. To improve interoperability with such legacy STAs allow a workaround OCV mode to be enabled to ignore OCVC=1 from the STA if it does not follow OCV requirements in the first protected exchange. This covers cases where a STA claims to have OCV capability, but it does not negotiate use of management frame protection or does not include OCI in EAPOL Key msg 2/4, FT Reassociation Request frame, or FILS (Re)Association Reqest. The previous behavior with ocv=1 is maintained, i.e., misbehaving STAs are not allowed to connect. When the new workaround mode is enabled with ocv=2, the AP considers STA as OCV capable on below criteria - STA indicates both OCV and MFP capability - STA sends OCI during connection attempt in a protected frame Enabling this workaround mode reduced OCV protection to some extend since it allows misbehavior to go through. As such, this should be enabled only if interoperability with misbehaving STAs is needed. Signed-off-by: Veerendranath Jakkam <vjakkam@codeaurora.org> |

This package may include either wpa_supplicant, hostapd, or both. See README file respective subdirectories (wpa_supplicant/README or hostapd/README) for more details. Source code files were moved around in v0.6.x releases and compared to earlier releases, the programs are now built by first going to a subdirectory (wpa_supplicant or hostapd) and creating build configuration (.config) and running 'make' there (for Linux/BSD/cygwin builds).
