cfg80211: add wowlan net-detect support

2014-11-19T17:45:45+00:00

Add a new WoWLAN API to enable net-detect as a wake up trigger.
Net-detect allows the device to scan in the background while the
host is asleep to wake up the host system when a matching network
is found.

Reuse the scheduled scan attributes to specify how the scan is
performed while suspended and the matches that will trigger a
wake event.

cfg80211: 802.11p OCB mode handling

2014-11-04T12:18:17+00:00

This patch adds new iface type (NL80211_IFTYPE_OCB) representing
the OCB (Outside the Context of a BSS) mode.
When establishing a connection to the network a cfg80211_join_ocb
function is called (particular nl80211_command is added as well).
A mandatory parameters during the ocb_join operation are 'center
frequency' and 'channel width (5/10 MHz)'.

Changes done in mac80211 are minimal possible required to avoid
many warnings (warning: enumeration value 'NL80211_IFTYPE_OCB'
not handled in switch) during compilation. Full functionality
(where needed) is added in the following patch.

cfg80211: fix elapsed_jiffies calculation

2014-06-23T09:29:25+00:00

MAX_JIFFY_OFFSET has no meaning when calculating the
elapsed jiffies, as jiffies run out until ULONG_MAX.

This miscalculation results in erroneous values
in case of a wrap-around.

cfg80211: export interface stopping function

2014-05-06T13:16:34+00:00

This exports a new cfg80211_stop_iface() function.

This is intended for driver internal interface
combination management and channel switching.

Due to locking issues (it re-enters driver) the
call is asynchronous and uses cfg80211 event
list/worker.

cfg80211: change wiphy_to_dev function name

2014-04-25T15:33:04+00:00

Name wiphy_to_rdev is more accurate to describe what the function
does, i.e., return a pointer pointing to struct
cfg80211_registered_device.

cfg80211: change registered device pointer name

2014-04-25T15:32:56+00:00

Name "dev" is too common and ambiguous, let all the pointer name
pointing to struct cfg80211_registered_device be "rdev". This can
improve code readability and consistency(since other places have
already called it rdev).

cfg80211/mac80211: move more combination checks to mac80211

2014-04-09T08:55:47+00:00

Get rid of the cfg80211_can_add_interface() and
cfg80211_can_change_interface() functions by moving that functionality
to mac80211.  With this patch all interface combination checks are now
out of cfg80211 (except for the channel switch case which will be
addressed in a future commit).

Additionally, modify the ieee80211_check_combinations() function so
that an undefined chandef can be passed, in order to use it before a
channel is defined.

cfg80211/mac80211: move interface counting for combination check to mac80211

2014-04-09T08:55:43+00:00

Move the counting part of the interface combination check from
cfg80211 to mac80211.

This is needed to simplify locking when the driver has to perform a
combination check by itself (eg. with channel-switch).

cfg80211: allow userspace to take ownership of interfaces

2014-04-09T08:55:28+00:00

When dynamically creating interfaces from userspace, e.g. for P2P usage,
such interfaces are usually owned by the process that created them, i.e.
wpa_supplicant. Should wpa_supplicant crash, such interfaces will often
cease operating properly and cause problems on restarting the process.

To avoid this problem, introduce an ownership concept for interfaces. If
an interface is owned by a netlink socket, then it will be destroyed if
the netlink socket is closed for any reason, including if the process it
belongs to crashed. This gives us a race-free way to get rid of any such
interfaces.

cfg80211: remove macro ASSERT_RDEV_LOCK(rdev)

2014-03-19T20:29:58+00:00

Macro ASSERT_RDEV_LOCK(rdev) is equal to ASSERT_RTNL(), so replace it
with ASSERT_RTNL() and remove it.
