2017-10-11mac80211: aead api to reduce redundancyXiang Gao
Currently, the aes_ccm.c and aes_gcm.c are almost line by line copy of each other. This patch reduce code redundancy by moving the code in these two files to crypto/aead_api.c to make it a higher level aead api. The file aes_ccm.c and aes_gcm.c are removed and all the functions there are now implemented in their headers using the newly added aead api.

2016-10-17mac80211: move struct aead_req off the stackArd Biesheuvel
Some crypto implementations (such as the generic CCM wrapper in crypto/) use scatterlists to map fields of private data in their struct aead_req. This means these data structures cannot live in the vmalloc area, which means that they cannot live on the stack (with CONFIG_VMAP_STACK.) This currently occurs only with the generic software implementation, but the private data and usage is implementation specific, so move the whole data structures off the stack into heap by allocating every time we need to use them. In addition, take care not to put any of our own stack allocations into scatterlists. This involves reserving some extra room when allocating the aead_request structures, and referring to those allocations in the scatter- lists (while copying the data from the stack before the crypto operation) Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-01-27mac80111: Add CCMP-256 cipherJouni Malinen
This allows mac80211 to configure CCMP-256 to the driver and also use software-implementation within mac80211 when the driver does not support this with hardware accelaration.

2013-10-11mac80211: port CCMP to cryptoapi's CCM driverArd Biesheuvel
Use the generic CCM aead chaining mode driver rather than a local implementation that sits right on top of the core AES cipher. This allows the use of accelerated implementations of either CCM as a whole or the CTR mode which it encapsulates.
