mac80211: count authorized stations per BSS

2011-12-15T19:46:34+00:00

Currently, each AP interface will send multicast
traffic if any interface has a station entry even
if that station entry is allocated only. With the
new station state management we can easily fix it
by adding a counter that counts each authorized
station only and send multicast traffic only when
the correct interface has at least one authorized
station.

mac80211: add ieee80211_vif param to tsf functions

2011-09-27T18:27:48+00:00

TSF can be kept per vif.
Add ieee80211_vif param to set/get/reset_tsf, and move
the debugfs entries to the per-vif directory.

Update all the drivers that implement these callbacks.

mac80211: Stop forwarding mesh traffic when tx queues are full

2011-09-14T17:56:17+00:00

Tx flow control for non-mesh modes of operation only needs to act on the
net device queues: when the hardware queues are full we stop accepting
traffic from the net device.  In mesh, however, we also need to stop
forwarding traffic.  This patch checks the hardware queues before
attempting to forward a mesh frame.

{nl,cfg,mac}80211: let userspace make meshif mesh gate

2011-08-24T17:59:43+00:00

Allow userspace to set NL80211_MESHCONF_GATE_ANNOUNCEMENTS attribute,
which will advertise this mesh node as being a mesh gate.
NL80211_HWMP_ROOTMODE must be set or this will do nothing.

mac80211: fix SMPS debugfs locking

2011-04-20T20:05:59+00:00

The locking with SMPS requests means that the
debugs file should lock the mgd mutex, not the
iflist mutex. Calls to __ieee80211_request_smps()
need to hold that mutex, so add an assertion.

This has always been wrong, but for some reason
never been noticed, probably because the locking
error only happens while unassociated.

mac80211: Add testing functionality for TKIP

2011-02-03T21:45:29+00:00

TKIP countermeasures depend on devices being able to detect Michael
MIC failures on received frames and for stations to report errors to
the AP. In order to test that behavior, it is useful to be able to
send out TKIP frames with incorrect Michael MIC. This testing behavior
has minimal effect on the TX path, so it can be added to mac80211 for
convenient use.

The interface for using this functionality is a file in mac80211
netdev debugfs (tkip_mic_test). Writing a MAC address to the file
makes mac80211 generate a dummy data frame that will be sent out using
invalid Michael MIC value. In AP mode, the address needs to be for one
of the associated stations or ff:ff:ff:ff:ff:ff to use a broadcast
frame. In station mode, the address can be anything, e.g., the current
BSSID. It should be noted that this functionality works correctly only
when associated and using TKIP.
