Zhu Yi 5a65694971 [PATCH] ieee80211: Fix TKIP and WEP decryption error on SMP machines
The IEEE80211 TKIP and WEP Tx and Rx paths use the same crypto_tfm to encrypt
and decrypt data. During the encrypt and decrypt process, both of them will
set a new key to crypto_tfm. If they happen on the same time, it will
corrupt the crypto_tfm. Thus users will receive an ICV error or Michael MIC
error. This only likely to happen on SMP box with heavy traffic both on Tx
and Rx. The patch use two sets of crypto_tfms to avoid this problem.

Zhu Yi 9184d9348a [PATCH] ieee80211: Add TKIP crypt->build_iv
This patch adds ieee80211 TKIP build_iv() method to support hardwares
that can do TKIP encryption but relies on ieee80211 layer to build
the IV. It also changes the build_iv() interface to return the key
if possible after the IV is built (this is required by TKIP).

James Ketrenos 6eb6edf04a [PATCH] ieee80211: in-tree driver updates to sync with latest ieee80211 series
Changed crypto method from requiring a struct ieee80211_device reference
to the init handler.  Instead we now have a get/set flags method for
each crypto component.

Setting of TKIP countermeasures can now be done via
set_flags(IEEE80211_CRYPTO_TKIP_COUNTERMEASURES)

tree 8428e9f510e6ad6c77baec89cb57374842abf733

Fix TKIP, repeated fragmentation problem, and payload_size reporting

1. TKIP encryption
    Originally, TKIP encryption issues msdu + mpdu encryption on every
    fragment. Change the behavior to msdu encryption on the whole
    packet, then mpdu encryption on every fragment.

2. Avoid repeated fragmentation when !host_encrypt.
    We only need do fragmentation when using host encryption. Otherwise
    we only need pass the whole packet to driver, letting driver do the
    fragmentation.

3. change the txb->payload_size to correct value
    FW will use this value to determine whether to do fragmentation. If
    we pass the wrong value, fw may cut on the wrong bound which will
    make decryption fail when we do host encryption.

NOTE:  This requires changing drivers (hostap) that have
extra_prefix_len used within them (structure member name change).

Renamed ieee80211_hdr to ieee80211_hdr_3addr and modified ieee80211_hdr
to just contain the frame_ctrl and duration_id.

Changed uses of ieee80211_hdr to ieee80211_hdr_4addr or
ieee80211_hdr_3addr based on what was expected for that portion of code.

NOTE: This requires changes to ipw2100, ipw2200, hostap, and atmel
drivers.

Fixed a kernel oops on module unload by adding spin lock protection to
ieee80211's crypt handlers (thanks to Zhu Yi)

Modified scan result logic to report WPA and RSN IEs if set (vs.being
based on wpa_enabled)

Added ieee80211_device as the first parameter to the crypt init()
method.  TKIP modified to use that structure for determining whether to
countermeasures are active.
