Since the kmem cache API doesn't internally allocate the name but just points to the name that was passed in we can't use stack memory for it. Move the name into the transport struct.

If the virtual monitor interface is requested by the driver, it should also be iterated over when the driver wants to iterate all active interfaces. To allow that protect it with the iflist_mtx.

To call cfg80211_get_chan_state() we need to lock the wdev, so we need to lock the wdev_iter mutex in cfg80211_can_use_iftype_chan(). This needs to use nested locking for lockdep. Also, cfg80211_get_chan_state() doesn't actually use the rdev, so remove that completely including the lock assertion that isn't needed.

When sample_idx is set to a value other than -1 it activates the IEEE80211_TX_CTL_RATE_CTRL_PROBE flag which disables frame aggregation. To allow frame aggregation during fixed rate it is necessary to set max_tp_rate, max_tp_rate2 and max_prob_rate instead of sample_idx.

Nicolas Cavallari authored
When drop_unencrypted is enabled and MFP is disabled, non-robust management frames for not-yet associated STA are dropped. This isn't visible as many management frames sent from the kernel have TX_INTFL_DONT_ENCRYPT set and management frames injected from a monitor vif have TX_CTL_INJECTED so aren't dropped. But management frames sent from userspace via NL80211_CMD_FRAME do not have this flag set, so are dropped. This patch make it always accept non-robust management frames.

Some drivers (iwlegacy, iwlwifi and rt2x00) today use the bss_conf.last_tsf value. By itself though that value is completely worthless since it may be ancient. What really is needed is synchronisation between some device time and the TSF. To clarify this, rename bss_conf.last_tsf to sync_tsf and add sync_device_ts which is obtained from rx_status which gets a new field device_timestamp for this purpose. This is intentionally not using the mactime field since that is used for other things and in IBSS is expected to sync with the IBSS's TSF which isn't necessarily true for the device timestamp. Also, since we have the information and it's useful even before the connection has been established, give all the timing details to the driver before authenticating.

We waste a lot of space in this struct because it uses int values where smaller ones would be sufficient. The upcoming A-MPDU information needs some space, optimize the struct now. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Scan receive is rather inefficient when there are multiple virtual interfaces. We iterate all of the virtual interfaces and then notify cfg80211 about each beacon many times. Redesign scan RX to happen before everything else. Then we can also get rid of IEEE80211_RX_IN_SCAN since we don't have to accept frames into the RX handlers for scanning or scheduled scanning any more. Overall, this simplifies the code.

Instead of tracking whether or not we're in a scheduled scan, track the virtual interface (sdata) in an RCU-protected pointer to make it usable from RX to check the MAC address. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Johannes Berg authored
Making the scan_sdata pointer usable with RCU makes it possible to dereference it in the RX path to see if a received frame actually matches the interface that is scanning. This is just preparations, making the pointer __rcu. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Arik Nemtsov authored
The function building probe-request IEs does not validate the band is supported before dereferencing it. This can result in a panic when all bands are traversed, as done during sched-scan start. Warn when this happens and return an empty probe request. Also fix sched-scan to not waste memory on unsupported bands.

This patch adds an alternative tx status path for BlockAck Requests as the hardware doesn't recognize that a BlockAck Requests is usually acked with a BlockAck and not a legacy ACK. Without this patch, the stack would constantly resent old and stale BARs. So, depending on the receiver stack, this could lead to: - "stuck" ba sessions and package loss, as the stale BAR would reset the sequence each time. - lots of reorder releases. - ...

Remove the CONT_* and LNA_* messages from AR_MCI_INTERRUPT_RX_MSG_DEFAULT. Those MCI rx messages only meant for debugging purpose. Including them in default rx_msg series could raise huge amount of MCI interrupts when BT traffic is going on. And also it increases power consumption when WLAN is scanning.
