Luciano Coelho a1f1c21c18 nl80211/cfg80211: add match filtering for sched_scan
Introduce filtering for scheduled scans to reduce the number of
unnecessary results (which cause useless wake-ups).

Add a new nested attribute where sets of parameters to be matched can
be passed when starting a scheduled scan.  Only scan results that
match any of the sets will be returned.

At this point, the set consists of a single parameter, an SSID.  This
can be easily extended in the future to support more complex matches.

Vivek Natarajan f4b34b550a cfg80211/nl80211: Indicate roaming feature capability to userspace.
When the rssi of the current AP drops, both wpa_supplicant and the
firmware may do a background scan to find a better AP and try to
associate. Since firmware based roaming is faster, inform
wpa_supplicant to avoid roaming and let the firmware decide to
roam if necessary.

For fullmac drivers like ath6kl, it is just enough to provide the
ESSID and the firmware will decide on the BSSID. Since it is not
possible to do pre-auth during roaming for fullmac drivers, the
wpa_supplicant needs to completely disconnect with the old AP and
reconnect with the new AP. This consumes lot of time and it is
better to leave the roaming decision to the firmware.

This patch updates the mesh peering frames to the format specified in
the recently ratified 802.11s standard. Several changes took place to
make this happen:

	- Change RX path to handle new self-protected frames
	- Add new Peering management IE
	- Remove old Peer Link IE
	- Remove old plink_action field in ieee80211_mgmt header

These changes by themselves would either break peering, or work by
coincidence, so squash them all into this patch.

attacks.

Now inetpeer is IPv6 aware, we can use it to provide a more secure and

This patch :
1) defines a new secure_ipv6_id() helper
2) extends inet_getid() to provide 32bit results
3) extends ipv6_select_ident() with a new dest parameter

Johannes Berg f850e00fcd mac80211: let key iteration get keys in install order
ieee80211_iter_keys() currently returns keys in
the backward order they were installed in, which
is a bit confusing. Add them to the tail of the
key list to make sure iterations go in the same
order that keys were originally installed in.
