cfg80211: process events caused by suspend before suspending

2016-10-26T05:59:52+00:00

When suspending without WoWLAN, cfg80211 will ask drivers to
disconnect. Even when the driver does this synchronously, and
immediately returns with a notification, cfg80211 schedules
the handling thereof to a workqueue, and may then call back
into the driver when the driver was already suspended/ing.

Fix this by processing all events caused by cfg80211_leave_all()
directly after that function returns. The driver still needs to
do the right thing here and wait for the firmware response, but
that is - at least - true for mwifiex where this occurred.

cfg80211: add ability to check DA/SA in A-MSDU decapsulation

2016-10-12T07:19:10+00:00

We should not accept arbitrary DA/SA inside A-MSDUs, it could be used
to circumvent protections, like allowing a station to send frames and
make them seem to come from somewhere else.

Add the necessary infrastructure in cfg80211 to allow such checks, in
further patches we'll start using them.

cfg80211: let ieee80211_amsdu_to_8023s() take only header-less SKB

2016-10-12T07:19:10+00:00

There's only a single case where has_80211_header is passed as true,
which is in mac80211. Given that there's only simple code that needs
to be done before calling it, export that function from cfg80211
instead and let mac80211 call it itself.

Merge remote-tracking branch 'net-next/master' into mac80211-next

2016-10-04T07:46:44+00:00

Resolve the merge conflict between Felix's/my and Toke's patches
coming into the tree through net and mac80211-next respectively.
Most of Felix's changes go away due to Toke's new infrastructure
work, my patch changes to "goto begin" (the label wasn't there
before) instead of returning NULL so flow control towards drivers
is preserved better.

cfg80211: Provide an API to report NAN function termination

2016-09-30T11:21:37+00:00

Provide a function that reports NAN DE function termination. The function
may be terminated due to one of the following reasons: user request,
ttl expiration or failure.
If the NAN instance is tied to the owner, the notification will be
sent to the socket that started the NAN interface only

cfg80211: provide a function to report a match for NAN

2016-09-30T11:21:32+00:00

Provide a function the driver can call to report a match.
This will send the event to the user space.
If the NAN instance is tied to the owner, the notifications will be
sent to the socket that started the NAN interface only.

cfg80211: allow the user space to change current NAN configuration

2016-09-30T11:21:28+00:00

Some NAN configuration paramaters may change during the operation of
the NAN device. For example, a user may want to update master preference
value when the device gets plugged/unplugged to the power.
Add API that allows to do so.

cfg80211: add add_nan_func / del_nan_func

2016-09-30T11:21:23+00:00

A NAN function can be either publish, subscribe or follow
up. Make all the necessary verifications and just pass the
request to the driver.
Allow the user space application that starts NAN to
forbid any other socket to add or remove functions.

cfg80211: add start / stop NAN commands

2016-09-30T11:21:14+00:00

This allows user space to start/stop NAN interface.
A NAN interface is like P2P device in a few aspects: it
doesn't have a netdev associated to it.
Add the new interface type and prevent operations that
can't be executed on NAN interface like scan.

Define several attributes that may be configured by user space
when starting NAN functionality (master preference and dual
band operation)

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.
