cfg80211: leave invalid channels on regdomain change

2014-11-28T13:33:41+00:00

When the regulatory settings change, some channels might become invalid.
Disconnect interfaces acting on these channels, after giving userspace
code a grace period to leave them.

This mode is currently opt-in, and not all interface operating modes are
supported for regulatory-enforcement checks. A wiphy that wishes to use
the new enforcement code must specify an appropriate regulatory flag,
and all its supported interface modes must be supported by the checking
code.

cfg80211: introduce TDLS channel switch commands

2014-11-19T17:45:12+00:00

Introduce commands to initiate and cancel TDLS channel-switching. Once
TDLS channel-switching is started, the lower level driver is responsible
for continually initiating channel-switch operations and returning to
the base (AP) channel to listen for beacons from time to time.

Upon cancellation of the channel-switch all communication between the
relevant TDLS peers will continue on the base channel.

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: avoid using default in interface type switch

2014-10-31T13:19:19+00:00

Most code avoids having a default case in interface type switch
statements already, to make it easier to find places that need
to be extended. Change the code in the __cfg80211_leave() and
nl80211_key_allowed() functions to not have a default case.

cfg80211: support creating wiphy with suggested name

2014-10-27T07:48:18+00:00

Kernel will attempt to use the name if it is supplied,
but if name cannot be used for some reason, the default
phyX name will be used instead.

"This time, I have some rate minstrel improvements, support for a very
small feature from CCX that Steinar reverse-engineered, dynamic ACK
timeout support, a number of changes for TDLS, early support for radio
resource measurement and many fixes. Also, I'm changing a number of
places to clear key memory when it's freed and Intel claims copyright
for code they developed."

cfg80211: clear wext keys when freeing and removing them

2014-09-11T10:07:28+00:00

When freeing the keys stored for wireless extensions, clear the memory
to avoid having the key material stick around in memory "forever".
Similarly, when userspace overwrites a key, actually clear it instead
of just setting the key length to zero.

cfg80211: add Intel Mobile Communications copyright

2014-09-05T11:52:06+00:00

Our legal structure changed at some point (see wikipedia), but
we forgot to immediately switch over to the new copyright
notice.

For files that we have modified in the time since the change,
add the proper copyright notice now.
