2014-10-27mac80211: don't flush when probing the APEmmanuel Grumbach
All the callers of ieee80211_mgd_probe_ap_send return right after they call the flush() callback. This means that calling flush() is uneeded since its meaning is to wait until the queues of the device are empty. Devices that know how to report status on Tx will do so using the regular path (ieee80211_tx_status) and this status will trigger the continuation of the flow of the probe (ieee80211_sta_tx_notify).

2014-10-23mac80211: minstrel_ht: use group flags instead of index to display ratesKarl Beldan
When displaying a rate through debugfs minstrel_ht guesses its flags comparing group indexes. Since 3ec373c421b6 ("mac80211: minstrel_ht: include type (cck/ht) in rates flag"), the rate flags of interest are present in the mcs_group-s, so use it. While improving the code, this also fixes a smatch false positive "error: testing array offset 'i' after use" in minstrel_ht_stats_dump. This warning only triggers after 9208247d74bc ("mac80211: minstrel_ht: add basic support for VHT rates <= 3SS@80MHz") with CONFIG_MAC80211_RC_MINSTREL_VHT unset because then MINSTREL_VHT_GROUP_0 is above MINSTREL_GROUPS_NB and smatch only barks when the "testing array offset" seems to prevent possible out of bonds accesses (which does not happen here since i < ARRAY_SIZE(mi->groups)).

2014-10-22mac80211: add WMM admission control supportJohannes Berg
Use the currently existing APIs between mac80211 and the low level driver to implement WMM admission control. The low level driver needs to report the media time used by each transmitted packet in ieee80211_tx_status. Based on that information, mac80211 will modify the QoS parameters of the admission controlled Access Category when the limit is reached. Once the original QoS parameters can be restored, mac80211 will do so. One issue with this approach is that management frames will also erroneously be downgraded, but the upside is that the implementation is simple. In the future, it can be extended to driver- or device-based implementations that are better.

When the new CONFIG_MAC80211_RC_MINSTREL_VHT is not set (default 'N'), there is no behavioral change including in sampling and MCS_GROUP_RATES remains 8. Otherwise MCS_GROUP_RATES is 10, and a module parameter *vht_only* (default 'true'), restricts the rates selection to VHT when VHT is supported.

2014-10-20mac80211: minstrel_ht: Increase the range of handled rate indexesKarl Beldan
Since 5935839ad735 ("mac80211: improve minstrel_ht rate sorting by throughput & probability"), the rate indexes are manipulated via u8's and hence allow for a maximum of 256 mcs_group entries in minstrel_mcs_groups. ATM, minstrel_ht advertizes support up to 3HTSS@40MHz, consuming: 8(MCS_GROUP_RATES) * (3(SS)*2(GI)*2(BW)+1(CCK)), i.e. 104 entries. Support for 3VHTSS@80MHz will require: 10(MCS_GROUP_RATES) * (3(SS)*2(GI)*2(BW)+1(CCK)) + 10(MCS_GROUP_RATES) * (3(SS)*2(GI)*3(BW)), i.e. 130 + 180 entries.

2014-10-20mac80211: minstrels: fix buffer overflow in HT debugfs rc_statsKarl Beldan
ATM an HT rc_stats line is 106 chars. Times 8(MCS_GROUP_RATES)*3(SS)*2(GI)*2(BW) + CCK(4), i.e. x100, this is well above the current 8192 - sizeof(*ms) currently allocated.

2014-10-14mac80211: fix typo in starting baserate for rts_cts_rate_idxKarl Beldan
It affects non-(V)HT rates and can lead to selecting an rts_cts rate that is not a basic rate or way superior to the reference rate (ATM rates[0] used for the 1st attempt of the protected frame data). E.g, assuming drivers register growing (bitrate) sorted tables of ieee80211_rate-s, having : - rates[0].idx == d'2 and basic_rates == b'10100 will select rts_cts idx b'10011 & ~d'(BIT(2)-1), i.e. 1, likewise - rates[0].idx == d'2 and basic_rates == b'10001 will select rts_cts idx b'10000 The first is not a basic rate and the second is > rates[0]. Also, wrt severity of the addressed misbehavior, ATM we only have one rts_cts_rate_idx rather than one per rate table entry, so this idx might still point to bitrates > rates[1..MAX_RATES].

There is a possible issue with the use, or lack thereof of sk_refcnt and sk_wmem_alloc in the wifi ack status functionality. Specifically if a socket were to request acknowledgements, and the socket were to have sk_refcnt drop to 0 resulting in it waiting on sk_wmem_alloc to reach 0 it would be possible to have sock_queue_err_skb orphan the last buffer, resulting in __sk_free being called on the socket.
