wifi: mac80211: refactor CMAC crypt functions

2025-11-20T10:56:19Z

ieee80211_aes_cmac() and ieee80211_aes_cmac_256() are almost the same. Merge them. This removes duplication. Signed-off-by: Chien Wong Link: https://patch.msgid.link/20251113140511.48658-5-m@xv97.com Signed-off-by: Johannes Berg

wifi: mac80211: utilize the newly defined CMAC constants

2025-11-20T10:56:19Z

Make use of the added constants to reduce duplication. Signed-off-by: Chien Wong Link: https://patch.msgid.link/20251113140511.48658-4-m@xv97.com Signed-off-by: Johannes Berg

wifi: mac80211: fix CMAC functions not handling errors

2025-11-20T10:56:18Z

The called hash functions could fail thus we should check return values. Fixes: 26717828b75d ("mac80211: aes-cmac: switch to shash CMAC driver") Signed-off-by: Chien Wong Link: https://patch.msgid.link/20251113140511.48658-2-m@xv97.com Signed-off-by: Johannes Berg

mac80211: aes_cmac: check crypto_shash_setkey() return value

2021-04-19T10:01:40Z

As crypto_shash_setkey() can fail, we should check the return value.

mac80211: Update BIP to support Beacon frames

2020-02-24T09:36:03Z

When BIP is used to protect Beacon frames, the Timestamp field is masked to zero. Otherwise, the BIP processing is identical to the way it was already used with group-addressed Robust Management frames.

mac80211: aes-cmac: switch to shash CMAC driver

2017-02-08T08:19:33Z

Instead of open coding the CMAC algorithm in the mac80211 driver using byte wide xors and calls into the crypto layer for each block of data, instantiate a cmac(aes) synchronous hash and pass all the data into it directly. This does not only simplify the code, it also allows the use of more efficient and more secure implementations, especially on platforms where SIMD ciphers have a considerable setup cost.

mac80211: FILS AEAD protection for station mode association frames

2016-10-27T14:03:25Z

This adds support for encrypting (Re)Association Request frame and decryption (Re)Association Response frame when using FILS in station mode. Signed-off-by: Jouni Malinen Signed-off-by: Johannes Berg

mac80211: remove ieee80211_aes_cmac_calculate_k1_k2()

2015-08-13T09:31:45Z

The iwlwifi driver was the only driver that used this, but as it turns out it never needed it, so we can remove it. Signed-off-by: Johannes Berg

mac80111: Add BIP-CMAC-256 cipher

2015-01-27T10:09:13Z

This allows mac80211 to configure BIP-CMAC-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
