wifi: mac80211: refactor CMAC packet handlers

2025-11-20T10:56:19Z

Merge CMAC-128 and CMAC-256 handlers since they are almost the same. This removes duplication. The comment 'MIC = AES-128-CMAC(IGTK, AAD ...' is out-dated since CMAC is also used with BIGTK, as is the comment for CMAC-256. Simply remove the comments.

wifi: mac80211: remove cipher scheme support

2022-06-10T13:35:53Z

The only driver using this was iwlwifi, where we just removed the support because it was never really used. Remove the code from mac80211 as well. Change-Id: I1667417a5932315ee9d81f5c233c56a354923f09 Signed-off-by: Johannes Berg

mac80111: Add BIP-GMAC-128 and BIP-GMAC-256 ciphers

2015-01-27T10:10:13Z

This allows mac80211 to configure BIP-GMAC-128 and BIP-GMAC-256 to the driver and also use software-implementation within mac80211 when the driver does not support this with hardware accelaration. Signed-off-by: Jouni Malinen Signed-off-by: Johannes Berg

mac80111: Add BIP-CMAC-256 cipher

mac80211: add generic cipher scheme support

2013-11-25T19:50:52Z

This adds generic cipher scheme support to mac80211, such schemes are fully under control by the driver. On hw registration drivers may specify additional HW ciphers with a scheme how these ciphers have to be handled by mac80211 TX/RR. A cipher scheme specifies a cipher suite value, a size of the security header to be added to or stripped from frames and how the PN is to be verified on RX.

mac80211: fix tx->skb NULL pointer dereference

2012-01-16T20:01:16Z

mac80211: 802.11w - Add BIP (AES-128-CMAC)

2009-01-29T21:00:02Z

Implement Broadcast/Multicast Integrity Protocol for management frame protection. This patch adds the needed definitions for the new information element (MMIE) and implementation for the new "encryption" type (though, BIP is actually not encrypting data, it provides only integrity protection). These routines will be used by a follow-on patch that enables BIP for multicast/broadcast robust management frames. Signed-off-by: Jouni Malinen Acked-by: Johannes Berg Signed-off-by: John W. Linville
