This patch adds new iface type (NL80211_IFTYPE_OCB) representing the OCB (Outside the Context of a BSS) mode. When establishing a connection to the network a cfg80211_join_ocb function is called (particular nl80211_command is added as well). A mandatory parameters during the ocb_join operation are 'center frequency' and 'channel width (5/10 MHz)'. Changes done in mac80211 are minimal possible required to avoid many warnings (warning: enumeration value 'NL80211_IFTYPE_OCB' not handled in switch) during compilation. Full functionality (where needed) is added in the following patch. Signed-off-by: NRostislav Lisovy <rostislav.lisovy@fel.cvut.cz> Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Most code avoids having a default case in interface type switch statements already, to make it easier to find places that need to be extended. Change the code in the __cfg80211_leave() and nl80211_key_allowed() functions to not have a default case. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

When CONFIG_MAC80211_RC_MINSTREL_VHT is set, the module param minstrel_vht_only tells minstrel_ht whether to allow the mix of ht rates with vht rates. ATM, minstrel_ht skips ht rates when minstrel_vht_only is true, but it does that even if vht is not supported, which makes the sta rates fallback to legacy as no ht rate gets enabled.

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).

During reconfig the station list is traversed in order and station are added back to the driver. Make sure the stations are added to the driver in the same order they were added to mac80211.

When displaying a rate through debugfs minstrel_ht guesses its flags comparing group indexes. Since 3ec373c4 ("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 9208247d ("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)).

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.

During the review of the corresponding wpa_supplicant patches we noticed that the only way for it to detect that this functionality is supported currently is to check for the command support. This can be misleading though, as the command was also designed to, in the future, support pure 802.11 TSPECs. Expose the WMM-TSPEC feature flag to nl80211 so later we can also expose an 802.11-TSPEC feature flag (if needed) to differentiate the two cases. Note: this change isn't needed in 3.18 as there's no driver there yet that supports the functionality at all. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

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. Regarding the debugfs stats buffer: It is explicitly increased from 8k to 32k to fit every rates incl. when both HT and VHT rates are enabled, as for the format, before: type rate tpt eprob *prob ret *ok(*cum) ok( cum) HT20/LGI ABCDP MCS0 0.0 0.0 0.0 1 0( 0) 0( 0) after: type rate tpt eprob *prob ret *ok(*cum) ok( cum) HT20/LGI ABCDP MCS0 0.0 0.0 0.0 1 0( 0) 0( 0) VHT40/LGI MCS5/2 0.0 0.0 0.0 0 0( 0) 0( 0) Signed-off-by: NKarl Beldan <karl.beldan@rivierawaves.com> Cc: Felix Fietkau <nbd@openwrt.org> Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

ATM, we grep cck rates idx with idx / MCS_GROUP_RATES == MINSTREL_CCK_GROUP.

Since 5935839a ("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. This change moves from u8s to u16s where necessary.
