cfg80211: Add support for static WEP in the driver

2016-09-30T11:19:10+00:00

Add support for drivers that implement static WEP internally, i.e.
expose connection keys to the driver in connect flow and don't
upload the keys after the connection.

cfg80211: allow connect keys only with default (TX) key

2016-09-15T14:45:41+00:00

There's no point in allowing connect keys when one of them
isn't also configured as the TX key, it would just confuse
drivers and probably cause them to pick something for TX.
Disallow this confusing and erroneous configuration.

As wpa_supplicant will always send NL80211_ATTR_KEYS, even
when there are no keys inside, allow that and treat it as
though the attribute isn't present at all.

cfg80211: reduce connect key caching struct size

2016-09-13T18:20:54+00:00

After the previous patches, connect keys can only (correctly)
be used for storing static WEP keys. Therefore, remove all the
data for dealing with key index 4/5 and reduce the size of the
key material to the maximum for WEP keys.

cfg80211: clear connect keys when freeing them

2014-09-11T10:07:18+00:00

When freeing the connect keys, clear the memory to avoid
having the key material stick around in memory "forever".

cfg80211: change wiphy_to_dev function name

2014-04-25T15:33:04+00:00

Name wiphy_to_rdev is more accurate to describe what the function
does, i.e., return a pointer pointing to struct
cfg80211_registered_device.

cfg80211: remove unused wiphy argument from cfg80211_wext_freq()

2014-04-10T08:06:19+00:00

cfg80211_wext_freq() is declared in wext-compat.h, but its
parameter struct wiphy's declaration is not included there.
As the parameter isn't used, just remove it.

cfg80211: remove macro ASSERT_RDEV_LOCK(rdev)

2014-03-19T20:29:58+00:00

Macro ASSERT_RDEV_LOCK(rdev) is equal to ASSERT_RTNL(), so replace it
with ASSERT_RTNL() and remove it.

cfg80211: separate internal SME implementation

2013-06-04T11:03:11+00:00

The current internal SME implementation in cfg80211 is
very mixed up with the MLME handling, which has been
causing issues for a long time. There are three things
that the implementation has to provide:
 * a basic SME implementation for nl80211's connect()
   call (for drivers implementing auth/assoc, which is
   really just mac80211) and wireless extensions
 * MLME events for the userspace SME
 * SME events (connected, disconnected etc.) for all
   different SME implementation possibilities (driver,
   cfg80211 and userspace)

To achieve these goals it isn't necessary to track the
software SME's connection status outside of it's state
(which is the part that caused many issues.) Instead,
track it only in the SME data (wdev->conn) and in the
general case only track whether the wdev is connected
or not (via wdev->current_bss.)

Also separate the internal implementation to not have
callbacks from the SME events, but rather call it from
the API functions that the driver (or rather mac80211)
calls. This separates the code better.

cfg80211: remove some locked wrappers from sme API

2013-05-24T22:02:22+00:00

By making all the API functions require wdev locking we
can clean up the API a bit, getting rid of the locking
version of each function. This also decreases the size
of cfg80211 by a small amount.
