* treewide: Switch DEFINE_TIMER callbacks to struct timer_list *Kees Cook2017-11-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes all DEFINE_TIMER() callbacks to use a struct timer_list pointer instead of unsigned long. Since the data argument has already been removed, none of these callbacks are using their argument currently, so this renames the argument to "unused". Done using the following semantic patch: @match_define_timer@ declarer name DEFINE_TIMER; identifier _timer, _callback; @@ DEFINE_TIMER(_timer, _callback); @change_callback depends on match_define_timer@ identifier match_define_timer._callback; type _origtype; identifier _origarg; @@ void -_callback(_origtype _origarg) +_callback(struct timer_list *unused) { ... } Signed-off-by: Kees Cook <keescook@chromium.org>

| | | | | | | | | | | | | | Set the NL80211_EXT_FEATURE_CQM_RSSI_LIST wiphy extended feature wholesale in all mac80211-based drivers that do not set the IEEE80211_VIF_BEACON_FILTER flags on their interfaces. mac80211 will be processing supplied RSSI values in ieee80211_rx_mgmt_beacon and will detect when the thresholds set by ieee80211_set_cqm_rssi_range_config are crossed. Remaining (few) drivers need code to enable the firmware to monitor the thresholds. This is mostly only compile-tested.

| | | | | | | | | | | | | | | | | | Add the following to support beacon report radio measurement with the measurement mode field set to passive or active: 1. Propagate the required scan duration to the device 2. Report the scan start time (in terms of TSF) 3. Report each BSS's detection time (also in terms of TSF) TSF times refer to the BSS that the interface that requested the scan is connected to.

| | | | | | | | | This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it.
