Michael MIC is an inherently weak algorithm that is specific to WPA
TKIP, which itself was an interim security solution to replace the
broken WEP standard.
Currently, the primary implementation of Michael MIC in the kernel is
the one in the mac80211 module. But there's also a duplicate
implementation in crypto/michael_mic.c which is exposed via the
crypto_shash API. It's used only by a few wireless drivers.
Seeing as Michael MIC is specific to WPA TKIP and should never be used
elsewhere, this series migrates those few drivers to the mac80211
implementation of Michael MIC, then removes the crypto implementation of
Michael MIC. This consolidates duplicate code and prevents other kernel
subsystems from accidentally using this insecure algorithm.
This series is targeting wireless-next.

Export the michael_mic() function so that it can be reused by the
ath11k, ath12k, and ipw2x00 drivers. Currently they have their own
local implementations of it based on crypto_shash, which is redundant
and inefficient.

While the ipw2100 and ipw2200 hardware is "Full MAC" in the sense that
it handles management frames (like association and scanning), it doesn't
implement various cryptographic protocols, such as the Michael MIC
algorithm used in the (deprecated) TKIP.
Currently ipw2x00 accesses Michael MIC via the crypto_shash API. Yet,
the mac80211 module already has its own Michael MIC implementation.
ipw2x00 is the only code in the kernel tree that needs a Michael MIC
implementation that doesn't already depend on CONFIG_MAC80211.
Just add the dependency on MAC80211 so that we'll be able to consolidate
the Michael MIC code in mac80211 and remove it from crypto_shash.
Alternatives considered:
- Move michael_mic() from mac80211 to cfg80211. Probably not worth it
just for ipw2x00.
- Move michael_mic() to its own independent module. Again, probably
not worth it just for ipw2x00.
- Copy michael_mic() into ipw2x00. It seems better to avoid the
duplicate copy.

Just use the michael_mic() function from mac80211 instead of a local
implementation of it on top of the crypto_shash API.

Remove the "michael_mic" crypto_shash algorithm, since it's no longer
used. Its only users were wireless drivers, which have now been
converted to use the michael_mic() function instead.

Thanks! I'll add a preparatory patch that temporarily renames the
michael_mic() in libipw_crypto_tkip.c.

If you're asking for 'select CRYPTO_MICHAEL_MIC' to be removed, that's
done in patch 5.
If you're asking for the "depends on" clause to be removed from LIBIPW
(but not IPW2100 and IPW2200), sure we can do that as part of this patch
if you want, since it's not actually necessary in LIBIPW.
