cfg80211: fix interface combinations check

2012-06-19T22:18:14+00:00

commit 463454b5dbd8dbab6e2fc6c557329e5b811b9c32 upstream.

If a given interface combination doesn't contain
a required interface type then we missed checking
that and erroneously allowed it even though iface
type wasn't there at all. Add a check that makes
sure that all interface types are accounted for.

net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules

2011-10-31T23:30:30+00:00

These files are non modular, but need to export symbols using
the macros now living in export.h -- call out the include so
that things won't break when we remove the implicit presence
of module.h from everywhere.

mac80211: data path modification for TDLS peers

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

Mark the STA entries of enabled TDLS peers with a new "peer authorized"
flag.

During link setup, allow special TDLS setup frames through the AP, but
otherwise drop all packets destined to the peer. This is required by the
TDLS (802.11z) specification in order to prevent reordering of MSDUs
between the AP and direct paths.

When setup completes and the peer is authorized, send data directly,
bypassing the AP.

In the Rx path, allow data to be received directly from TDLS peers.

cfg80211: Validate cipher suite against supported ciphers

2011-09-27T18:29:54+00:00

Instead of using a hardcoded list of cipher suites in nl80211.c, use a
shared function in util.c to verify that the driver advertises support
for the specified cipher. This provides more accurate validation of the
values and allows vendor-specific cipher suites to be added in drivers.

wireless: Remove unnecessary OOM logging messages

2011-09-13T19:45:02+00:00

Removing unnecessary messages saves code and text.

Site specific OOM messages are duplications of a generic MM
out of memory message and aren't really useful, so just
delete them.

mac80211: update mesh peering frame format

2011-08-22T18:46:00+00:00

This patch updates the mesh peering frames to the format specified in
the recently ratified 802.11s standard. Several changes took place to
make this happen:

	- Change RX path to handle new self-protected frames
	- Add new Peering management IE
	- Remove old Peer Link IE
	- Remove old plink_action field in ieee80211_mgmt header

These changes by themselves would either break peering, or work by
coincidence, so squash them all into this patch.

cfg80211/mac80211: move information element parsing logic to cfg80211

2011-08-12T17:45:03+00:00

Moving the parsing logic for retrieving the information elements
stored in management frames, e.g. beacons or probe responses,
and making it available to other cfg80211 drivers.

cfg80211: fix scan crash on single-band cards

     cfg80211: allow userspace to control supported rates in scan

made single-band cards crash since it would always
access all wiphy->bands[]. Fix this and reject any
attempts in the new helper ieee80211_get_ratemask()
to do the same, rejecting rates configuration for
unsupported bands.

cfg80211: allow userspace to control supported rates in scan

2011-07-19T20:49:58+00:00

Some P2P scans are not allowed to advertise
11b rates, but that is a rather special case
so instead of having that, allow userspace
to request the rate sets (per band) that are
advertised in scan probe request frames.

Since it's needed in two places now, factor
out some common code parsing a rate array.
