nl80211: ensure interface is up in various APIs

2012-05-11T12:14:40+00:00

commit 2b5f8b0b44e17e625cfba1e7b88db44f4dcc0441 upstream.
[backported by Ben Greear]

The nl80211 handling code should ensure as much as
it can that the interface is in a valid state, it
can certainly ensure the interface is running.

Not doing so can cause calls through mac80211 into
the driver that result in warnings and unspecified
behaviour in the driver.

nl80211: fix MAC address validation

2011-11-28T18:46:40+00:00

MAC addresses have a fixed length. The current
policy allows passing < ETH_ALEN bytes, which
might result in reading beyond the buffer.

cfg80211: allow setting TXQ parameters only in AP mode

2011-11-07T18:19:14+00:00

In other modes the parameters should not be set.
Right now, mac80211 will set them, even if the
user asked for setting them on VLANs which the
driver doesn't know about, causing all kinds of
trouble.

nl80211: fix HT capability attribute validation

2011-11-07T18:19:13+00:00

Since the NL80211_ATTR_HT_CAPABILITY attribute is
used as a struct, it needs a minimum, not maximum
length. Enforce that properly. Not doing so could
potentially lead to reading after the buffer.

nl80211: Add sta_flags to the station info

2011-10-14T18:48:23+00:00

Reuse the already existing struct nl80211_sta_flag_update to specify
both, a flag mask and the flag set itself. This means
nl80211_sta_flag_update is now used for setting station flags and also
for getting station flags.

nl80211/mac80211: allow adding TDLS peers as stations

2011-09-30T19:57:08+00:00

When adding a TDLS peer STA, mark it with a new flag in both nl80211 and
mac80211. Before adding a peer, make sure the wiphy supports TDLS and
our operating mode is appropriate (managed).

In addition, make sure all peers are removed on disassociation.

A TDLS peer is first added just before link setup is initiated. In later
setup stages we have more info about peer supported rates, capabilities,
etc. This info is reported via nl80211_set_station().

nl80211: support sending TDLS commands/frames

2011-09-30T19:57:05+00:00

Add support for sending high-level TDLS commands and TDLS frames via
NL80211_CMD_TDLS_OPER and NL80211_CMD_TDLS_MGMT, respectively. Add
appropriate cfg80211 callbacks for lower level drivers.

Add wiphy capability flags for TDLS support and advertise them via
nl80211.

cfg80211/mac80211: apply station uAPSD parameters selectively

2011-09-30T19:57:03+00:00

Currently, when hostapd sets the station as authorized
we also overwrite its uAPSD parameter. This obviously
leads to buggy behaviour (later, with my patches that
actually add uAPSD support). To fix this, only apply
those parameters if they were actually set in nl80211,
and to achieve that add a bitmap of things to apply.

mac80211: treat the WME sta flag as a bit

2011-09-27T18:36:04+00:00

Correct flag usage - use it as a bit index instead of a bit value.
