There are a number of situations in which mac80211 only
really needs to flush queues for one virtual interface,
and in fact during this frames might be transmitted on
other virtual interfaces. Calculate and pass a queue
bitmap to the driver so it knows which queues to flush.Signed-off-by: Johannes Berg

This basically reverts commit b207cdb07f3f01ec1adaac62e9d0cc918c60a81a.
Now is possible to use drv_{add,remove}_interface() and vif->debugfs_dir
to create/remove per interface debugfs files. Remove redundant
callbacks.Signed-off-by: Stanislaw Gruszka
Signed-off-by: Johannes Berg -
There is need create driver own per interface debugfs files. This is
currently done by drv_{add,remove}_interface_debugfs() callbacks. But it
is possible that after we remove interface from the driver (i.e.
on suspend) we call drv_remove_interface_debugfs() function. Fixing this
problem will require to add call drv_{add,remove}_interface_debugfs()
anytime we create and remove interface in mac80211. So it's better to
add debugfs dir dentry to vif structure to allow to create/remove
custom debugfs driver files on drv_{add,remove}_interface().Signed-off-by: Stanislaw Gruszka

Since the idle decision rework, mac80211 started calling
bss_info_changed() for the driver's monitor interface,
which causes a crash for iwlwifi, but drivers generally
don't expect this to happen. Therefore, avoid it.While at it, also prevent calling it in such cases and
only print a warning. For the P2P Device interface the
idle will no longer be called (no channel context), so
also prevent that and warn on it.Reported-by: Chaitanya

Add debugfs driver callbacks so drivers can add
debugfs entries for interfaces. Note that they
_must_ remove the entries again as add/remove in
the driver doesn't correspond to add/remove in
debugfs; the former is up/down while the latter
is netdev create/destroy.Signed-off-by: Alexander Bondar

To be able to implement NS response offloading (in
regular operation or while in WoWLAN) drivers need
to know the IPv6 addresses assigned to interfaces.
Implement an IPv6 notifier in mac80211 to call the
driver when addresses change.Unlike for IPv4, implement it as a callback rather
than as a list in the BSS configuration, that is
more flexible.Signed-off-by: Johannes Berg

There are hardwares which support offload of data packets
for example when auto ARP is enabled the hw will send
the ARP response. In such cases if WEP encryption is
configured the hw must know the default WEP key in order
to encrypt the packets correctly.When hw_accel is enabled and encryption type is set to WEP,
the driver should get the default key index from mac80211.Signed-off-by: Yoni Divinsky

Instead of checking every time bss_info_changed is called,
assign the pointer once depending on the interface type
and then leave it untouched until the interface type is
changed. This makes the ieee80211_bss_info_change_notify()
now a simple wrapper to call the driver only.Signed-off-by: Johannes Berg

As mwifiex (and mac80211 in the software case) are the
only drivers actually implementing remain-on-channel
with channel type, userspace can't be relying on it.
This is the case, as it's used only for P2P operations
right now.Rather than adding a flag to tell userspace whether or
not it can actually rely on it, simplify all the code
by removing the ability to use different channel types.
Leave only the validation of the attribute, so that if
we extend it again later (with the needed capability
flag), it can't break userspace sending invalid data.Signed-off-by: Johannes Berg

After cfg80211 got a P2P Device abstraction, add
support to mac80211. Whether it really is supported
or not will depend on whether or not the driver has

able to support drivers that need a P2P Device.Signed-off-by: Johannes Berg

In IBSS it is possible that the supported rates set for a station changes over
time (e.g. it gets first initialised as an empty set because of no available
information about rates and updated later). In this case the driver has to be
notified about the change in order to update its internal table accordingly (if
needed).This behaviour is needed by all those drivers that handle rc internally but
leave stations management to mac80211Reported-by: Gui Iribarren

Some drivers require setup before being able to send
management frames in managed mode, in particular in
multi-channel cases.Introduce API to allow the drivers to do such setup
while being able to sleep waiting for the setup to
finish in the device. This isn't possible inside the
TX call since that can't sleep.A future patch may also restructure the TX retry to
wait for the driver to report the frame status, as
suggested by Arik in

In WoWLAN, we only get the triggers when we actually get
to suspend. As a consequence, drivers currently don't
know that the device should enable wakeup. However, the
device_set_wakeup_enable() API is intended to be called
when the wakeup is enabled, not later when needed.Add a new set_wakeup() call to cfg80211 and mac80211 to
allow drivers to properly call device_set_wakeup_enable.Signed-off-by: Johannes Berg

The queue mapping redesign that I'm planning to do
will break pure injection unless we handle monitor
interfaces explicitly. One possible option would
be to have the driver tell mac80211 about monitor
mode queues etc., but that would duplicate the API
since we already need to have queue assignments
handled per virtual interface.So in order to solve this, have a virtual monitor
interface that is added whenever all active vifs
are monitors. We could also use the state of one
of the monitor interfaces, but managing that would
be complicated, so allocate separate state.Signed-off-by: Johannes Berg

Instead of maintaining separate sta_add/sta_remove
callsites, implement it in sta_state when the driver
has no sta_state implementation.The only behavioural change this should cause is in

(based on Eliad's patch)
Add a callback to notify the low-level driver whenever
the state of a station changes. The driver is only
notified when the station is actually in the mac80211
hash table, not for pre-insert state transitions.To allow the driver to replace sta_add/remove calls
with this, call extra transitions with the NOTEXIST
state.This callback can fail, so we need to be careful in
handling it when a station is inserted, particularly
in the IBSS case where we still keep the station entry
around for mac80211 purposes.Signed-off-by: Eliad Peller
