mac80111: Add BIP-CMAC-256 cipher

2015-01-27T10:09:13+00:00

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.

mac80211: include export.h in aes_cmac

2012-11-07T17:01:54+00:00

This is needed since this file exports functions.

mac80211: expose AES-CMAC subkey calculation

2012-10-23T17:52:52+00:00

Expose a function for the AES-CMAC subkey calculation
to drivers. This is the first step of the AES-CMAC
cipher key setup and may be required for CMAC hardware
offloading.

mac80211: simplify buffers in aes_128_cmac_vector

2012-08-20T12:03:18+00:00

There's no need to use a single scratch buffer and
calculate offsets into it, just use two separate
buffers for the separate variables.

mac80211: use AES_BLOCK_SIZE

2011-07-08T15:11:24+00:00

mac80211 has a defnition of AES_BLOCK_SIZE and
multiple definitions of AES_BLOCK_LEN. Remove
them all and use crypto/aes.h.

mac80211: fix CMAC races

2011-07-08T15:11:20+00:00

Just like TKIP and CCMP, CMAC has the PN race.
It might not actually be possible to hit it now
since there aren't multiple ACs for management
frames, but fix it anyway.

Also move scratch buffers onto the stack.

mac80211: Remove redundant checks for NULL before calls to crypto_free_cipher()

2010-11-15T18:26:11+00:00

crypto_free_cipher() is a wrapper around crypto_free_tfm() which is a
wrapper around crypto_destroy_tfm() and the latter can handle being passed
a NULL pointer, so checking for NULL in the
ieee80211_aes_key_free()/ieee80211_aes_cmac_key_free() wrappers around
crypto_free_cipher() is pointless and just increase object code size
needlesly and makes us execute extra test/branch instructions that we
don't need.
Btw; don't we have to many wrappers around wrappers ad nauseam here?
Anyway, this patch removes the redundant conditionals.

mac80211: Don't squash error codes in key setup functions

2010-08-16T19:26:38+00:00

ieee80211_add_key() currently returns -ENOMEM in case of any error,
including a missing crypto algorithm.  Change ieee80211_key_alloc()
and ieee80211_aes_{key_setup_encrypt,cmac_key_setup}() to encode
errors with ERR_PTR() rather than returning NULL, and change
ieee80211_add_key() accordingly.

Compile-tested only.

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

2009-01-29T21:00:02+00:00

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.
