Section 11.23.1 of 80211-2016 specification allows TDLS peers to operate on wider bandwidths though they are connected to a BSS which do not support wider bandwidth operations, provided both the peers advertise wider bandwidth capabilities. The existing logic considers the minimum of station's and AP's capability for bandwidth computation. The same logic applies for TDLS peers as well, this restricts operating on wider bandwidths over a TDLS link when the peers are connected to legacy APs. As an example, if 80Mhz VHT capable peers are connected to a 20Mhz 5 GHz AP, then as per the existing logic TDLS operation will be restricted to 20Mhz. Address this problem by not considering BSS capability in bandwidth computation if the participating TDLS peers have wider bandwidth capability. Signed-off-by:

According to IEEE Std 802.11-2016 (16.2.3.4 Long PHY SIGNAL field) all of the following rates are mandatory for a HR/DSSS PHY: 1 Mb/s, 2 Mb/s, 5.5 Mb/s and 11 Mb/s. Set IEEE80211_RATE_MANDATORY_B flag for all of these instead of just 1 Mb/s to correctly reflect this. Signed-off-by:

Sometimes a station is added already in ASSOC state. For example, in AP mode, when a client station didn't get assoc resp and sends an assoc req again. If a station is inserted when its state is ASSOC or higher, the min chandef and allow_p2p_go_ps should be recalculated again after the insertion. Before this patch the recalculation happened only in sta_info_move_state which occurs before the insertion of the sta and thus even though it calls ieee80211_recalc_min_chandef/_p2p_go_ps_allowed functions, since sdata->local->sta_list is still empty at this point, it doesn't do anything.

The user space can now allow the kernel to associate to an AP that requires MFP or that doesn't have MFP enabled in the same NL80211_CMD_CONNECT command, by using a new NL80211_MFP_OPTIONAL flag. The driver / firmware will decide whether to use it or not. Include a feature bit to advertise support for NL80211_MFP_OPTIONAL. This allows new user space to run on old kernels and know that it cannot use the new attribute if it isn't supported. Signed-off-by:

The mac80211_hwsim doesn't offer a way to disable the debugging output. Unfortunately, it's pretty chatty, dumping a lot of stuff into the message buffer. This patch changes it to use dyndbg for controlling the debug output. It's disabled by default, but can be enabled by a module parameter (1), at runtime (2) or persisted in modprobe.conf (3). (1) modprobe mac80211_hwsim dyndbg=+p (2) echo "module mac80211_hwsim +p" >/sys/kernel/debug/dynamic_debug/control (3) echo "options mac80211_hwsim dyndbg=+p" >>/etc/modprobe.d/my.conf Signed-off-by:

When NL80211_ATTR_WIPHY_CHANNEL_TYPE is given, nl80211 would parse the channel definition the old way, discarding NL80211_ATTR_CENTER_FREQ1, NL80211_ATTR_CENTER_FREQ2 etc. However, it is possible that user space added both NL80211_ATTR_WIPHY_CHANNEL_TYPE and NL80211_ATTR_CENTER_FREQ1 or NL80211_ATTR_CENTER_FREQ2 assuming that all settings would be honored. In such a case, validate that NL80211_ATTR_CENTER_FREQ1 and NL80211_ATTR_CENTER_FREQ2 values match the channel configuration, as otherwise user space would assume that the desired configuration was applied. For example, when trying to start ap with NL80211_ATTR_WIPHY_CHANNEL_TYPE = NL80211_CHAN_HT40MINUS, NL80211_ATTR_WIPHY_FREQ = 5180 and NL80211_ATTR_CENTER_FREQ1 = 5250 without this fix, the ap will start on channel 36 (center_freq1 will be corrected to 5180). With this fix, we will throw an error instead. Signed-off-by:

When such interrupts occur there is not much we can do. Dropping the whole ring doesn't help and only produces high packet loss. If we just ignore the interrupt the mac will drop one or few packets instead of the whole ring. Also this will lower the irq handling load and increase performance. Signed-off-by:

HiperSockets allow configuring so called VNIC Characteristics (VNICC) that influence how the underlying hardware handles packets. For VNICCs, additional commands for getting and setting timeouts are available. Currently, the learning VNICC uses these commands. * Learning VNICC: If learning is enabled on a qeth device, the device learns the source MAC addresses of outgoing packets and incoming packets to those learned MAC addresses are received. For learning, the timeout specifies the idle period in seconds, after which the underlying hardware removes a learned MAC address again. This patch adds support for the IPA commands that are required to get and set the current timeout values for the learning VNIC characteristic. Also, it introduces the sysfs interface that allows users to configure the timeout. Signed-off-by:

HiperSocket devices allow enabling and disabling so called VNIC Characteristics (VNICC) that influence how the underlying hardware handles packets. These VNICCs are: * Flooding VNICC: Flooding allows specifying if packets to unknown destination MAC addresses are received by the qeth device. * Multicast flooding VNICC: Multicast flooding allows specifying if packets to multicast MAC addresses are received by the qeth device. * Learning VNICC: If learning is enabled on a qeth device, the device learns the source MAC addresses of outgoing packets and incoming packets to those learned MAC addresses are received. * Takeover setvmac VNICC: If takeover setvmac is configured on a qeth device, the MAC address of this device can be configured on a different qeth device with the setvmac IPA command. * Takeover by learning VNICC: If takeover learning is enabled on a qeth device, the MAC address of this device can be learned (learning VNICC) on a different qeth device. * BridgePort invisible VNICC: If BridgePort invisible is enabled on a qeth device, (1) packets from this device are not sent to a BridgePort enabled qeth device and (2) packets coming from a BridgePort enabled qeth device are not received by this device. * Receive broadcast VNICC: Receive broadcast allows configuring if a qeth device receives packets with the broadcast destination MAC address. This patch adds support for the IPA commands that are required to enable and disable these VNIC characteristics on qeth devices. As a prerequisite, it also adds the query commands IPA command. The query commands IPA command allows requesting the supported commands for each characteristic from the underlying hardware. Additionally, this patch provides users with a sysfs user interface to enable/disable the VNICCs mentioned above. Signed-off-by:

VNIC Characteristics (VNICC) are features of HiperSockets that define how packets are handled by the underlying network hardware. For example, if the VNICC flooding is configured on a qeth device, ethernet frames to unknown destination MAC addresses are received. Currently, there is support for seven VNICCs: flooding, multicast flooding, receive broadcast, learning, takeover learning, takeover setvmac, bridge invisible. Also, six IPA commands exist for configuring VNICCs on a qeth device: query characteristics, query commands, enable characteristic, disable characteristic, set timeout, get timeout. This patch adds the basic code infrastructure for VNICC support to qeth. It allows querying VNICC support from the underlying hardware. To this end, it adds: * basic message formats for IPA commands * basic data structures * basic error handling * query characteristics IPA command support The query characteristics IPA command allows requesting the currently supported and currently enabled VNIC characteristics from the underlying hardware. Support for the other IPA commands and for the configuration of VNICCs is added in follow-up patches together with the respective user interface functions. Signed-off-by:
