nl80211: PMKSA caching support

2009-11-28T20:05:05+00:00

This is an interface to set, delete and flush PMKIDs through nl80211.
Main users would be fullmac devices which firmwares are capable of
generating the RSN IEs for the re-association requests, e.g. iwmc3200wifi.

cfg80211: return channel noise via survey API

2009-11-13T22:43:58+00:00

This patch implements the NL80211_CMD_GET_SURVEY command and an get_survey()
ops that a driver can implement. The goal of this command is to allow a
drivers to report channel survey data (e.g. channel noise, channel
occupation).

For now, only the mechanism to report back channel noise has been
implemented.

In future, there will either be a survey-trigger command --- or the existing
scan-trigger command will be enhanced. This will allow user-space to
request survey for arbitrary channels.

Note: any driver that cannot report channel noise should not report
any value at all, e.g. made-up -92 dBm.

nl80211: report age of scan results

2009-10-07T20:39:42+00:00

Linux keeps scan results up to 15 seconds. This can be a problem for fast
moving clients: they get back stale data. But if the kernel reports the age
of the BSS items, then user-space can simply weed out old entries by itself.

nl80211: add generation number to all dumps

2009-08-14T13:13:43+00:00

In order for userspace to be able to figure out whether
it obtained a consistent snapshot of data or not when
using netlink dumps, we need to have a generation number
in each dump message that indicates whether the list has
changed or not -- its value is arbitrary.

This patch adds such a number to all dumps, this needs
some mac80211 involvement to keep track of a generation
number to start with when adding/removing mesh paths or
stations.

The wiphy and netdev lists can be fully handled within
cfg80211, of course, but generation numbers need to be
stored there as well.

cfg80211: make aware of net namespaces

2009-07-27T19:24:07+00:00

In order to make cfg80211/nl80211 aware of network namespaces,
we have to do the following things:

 * del_virtual_intf method takes an interface index rather
   than a netdev pointer - simply change this

 * nl80211 uses init_net a lot, it changes to use the sender's
   network namespace

 * scan requests use the interface index, hold a netdev pointer
   and reference instead

 * we want a wiphy and its associated virtual interfaces to be
   in one netns together, so
    - we need to be able to change ns for a given interface, so
      export dev_change_net_namespace()
    - for each virtual interface set the NETIF_F_NETNS_LOCAL
      flag, and clear that flag only when the wiphy changes ns,
      to disallow breaking this invariant

 * when a network namespace goes away, we need to reparent the
   wiphy to init_net

 * cfg80211 users that support creating virtual interfaces must
   create them in the wiphy's namespace, currently this affects
   only mac80211

The end result is that you can now switch an entire wiphy into
a different network namespace with the new command
	iw phy# set netns 
and all virtual interfaces will follow (or the operation fails).

nl80211: report BSS status

2009-07-24T19:05:11+00:00

When connected to a BSS, or joined to an IBSS, we'll want
to know in userspace without using wireless extensions, so
report the BSS status in the BSS list. Userspace can query
the BSS list, display all the information and retrieve the
station information as well.

For example (from hwsim):

$ iw dev wlan1 scan dump
BSS 02:00:00:00:00:00 (on wlan1) -- associated
	freq: 2462
	beacon interval: 100
	capability: ESS ShortSlotTime (0x0401)
	signal: -50.00 dBm
	SSID: j
	Supported rates: 1.0* 2.0* 5.5* 11.0* 6.0 9.0 12.0 18.0
	DS Paramater set: channel 11
	ERP: 
	Extended supported rates: 24.0 36.0 48.0 54.0

cfg80211: rework key operation

2009-07-24T19:05:09+00:00

This reworks the key operation in cfg80211, and now only
allows, from userspace, configuring keys (via nl80211)
after the connection has been established (in managed
mode), the IBSS been joined (in IBSS mode), at any time
(in AP[_VLAN] modes) or never for all the other modes.

In order to do shared key authentication correctly, it
is now possible to give a WEP key to the AUTH command.
To configure static WEP keys, these are given to the
CONNECT or IBSS_JOIN command directly, for a userspace
SME it is assumed it will configure it properly after
the connection has been established.

Since mac80211 used to check the default key in IBSS
mode to see whether or not the network is protected,
it needs an update in that area, as well as an update
to make use of the WEP key passed to auth() for shared
key authentication.
