Jouni Malinen 2d5d4b0a6d mac80211: Update BIP to support Beacon frames
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.

Ard Biesheuvel f4a067f9ff mac80211: move struct aead_req off the stack
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)

Herbert Xu 957e0fe629 mac80211: Switch to new AEAD interface
This patch makes use of the new AEAD interface which uses a single
SG list instead of separate lists for the AD and plain text.

Jouni Malinen 82ca6ef686 mac80211: Fix misplaced return in AES-GMAC key setup
Commit 8ade538bf3 ("mac80111: Add BIP-GMAC-128 and BIP-GMAC-256
ciphers") had the success return in incorrect place before the
crypto_aead_setauthsize() call which practically ended up skipping that
call unconditionally.

The missing call did not actually change any functionality since
GMAC_MIC_LEN (16) is identical to the maxauthsize in gcm(aes) and as
such, the default value used for the authsize parameter.

Jouni Malinen 8ade538bf3 mac80111: Add BIP-GMAC-128 and BIP-GMAC-256 ciphers
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.
