In beacon filtering there needs to be a way to not expire the BSS even when no beacons are received. Add an interface to cfg80211 to hold BSS and make sure that it's not expired. Signed-off-by: NKalle Valo <kalle.valo@nokia.com> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

When devices are world roaming they cannot beacon or do active scan on 5 GHz or on channels 12, 13 and 14 on the 2 GHz band. Although we have a good regulatory API some cards may _always_ world roam, this is also true when a system does not have CRDA present. Devices doing world roaming can still passive scan, if they find a beacon from an AP on one of the world roaming frequencies we make the assumption we can do the same and we also remove the passive scan requirement. This adds support for providing beacon regulatory hints based on scans. This works for devices that do either hardware or software scanning. If a channel has not yet been marked as having had a beacon present on it we queue the beacon hint processing into the workqueue. All wireless devices will benefit from beacon regulatory hints from any wireless device on a system including new devices connected to the system at a later time. Signed-off-by: NLuis R.

It wasn't a good idea to make the signal type a per-BSS option, although then it is closer to the actual value. Move it to be a per-wiphy setting, update mac80211 to match. Signed-off-by: NJohannes Berg <johannes@sipsolutions.net> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

Due to various bugs in the software stack we end up having to fill qual.qual; level should be used, but wpa_supplicant doesn't properly ignore qual.qual, NM should use qual.level regardless of that because qual.qual is 0 but doesn't handle IW_QUAL_DBM right now. So fill qual.qual with the qual.level value clamped to -110..-40 dBm or just the regular 'unspecified' signal level. This requires a mac80211 change to properly announce the max_qual.qual and avg_qual.qual values. Signed-off-by: NJohannes Berg <johannes@sipsolutions.net> Signed-off-by: NJohn W.

Scanned BSS entries are timestamped with jiffies, which doesn't increment across suspend and hibernate. On resume, every BSS in the scan list looks like it was scanned within the last 10 seconds, irregardless of how long the machine was actually asleep. Age scan results on resume with the time spent during sleep so userspace has a clue how old they really are. Signed-off-by: NDan Williams <dcbw@redhat.com> Signed-off-by: NJohn W.

Add a more flexible BSS lookup function so that mac80211 or other drivers can actually use this for getting the BSS to connect to. Signed-off-by: NJohannes Berg <johannes@sipsolutions.net> Signed-off-by: NJohn W. Linville <linville@tuxdriver.com>

This patch introduces cfg80211_unlink_bss, a function to allow a driver to remove a BSS from the internal list and make it not show up in scan results any more -- this is to be used when the driver detects that the BSS is no longer available.

When cfg80211 users have their own allocated data in the per-BSS private data, they will need to free this when the BSS struct is destroyed. Add a free_priv method and fix one place where the BSS was kfree'd rather than released properly. Signed-off-by: NJohannes Berg <johannes@sipsolutions.net> Signed-off-by: NJohn W.

This patch adds basic scan capability to cfg80211/nl80211 and changes mac80211 to use it. The BSS list that cfg80211 maintains is made driver-accessible with a private area in each BSS struct, but mac80211 doesn't yet use it. That's another large project.
