Pass hidden SSID information to FW for proper operation. In order to be able to scan/connect to the hidden SSID, SSID setting is added when scan is requested from FW. SSID scanning currently supports single SSID due to FW limitation. Signed-off-by:

When one client is associated and connected to an ar6003 hw version 2.0 with firmware 3.1.1.149, and another client tries to connect, the first client's MAC address is lost in the station list because the "aid" is always "1". The structure "wmi_connect_event" has the "aid" as the second byte in the message, but it should be the first byte. This patch has been tested with linux-3.10.40 Signed-off-by:

In the midst of chanctx patch review channel switching became broken which I failed to notice until now. Function ath10k_mac_vif_chan() reports current chandef which isn't updated until after switch_vif_chanctx() is returned from. Consequently the driver just restarted operation on channels it was residing already instead of switching to the new ones. Fixes: 500ff9f9 ("ath10k: implement chanctx API") Signed-off-by:

In practice there's no point in having a copy of chanctx_conf. Most of the time the channel pointer (and band along with it) is accessed and this can't change after a chanctx is created because switching is done using explicit chanctx swapping via switch_vif_chanctx(). The only thing that can change within a chanctx_conf and is used by the driver is radar_enabled and channel width. These are however always accessed in adequate mac80211 callback context which guarantees safe access to the chanctx data. Signed-off-by:

Channel contexts aren't iterable until after they've been added to the driver. The code assumed otherwise. This problem could result in: * rx_channel being NULL and forcing Rx path to go the slow way to get channel on QCA988X, * report incorrect channel when running multi-channel on QCA61X4 hw2.1, * report incorrect channel after AP channel switch.

Some of of qca988x solutions are having global reset issue during target initialization. Bypassing PLL setting before downloading firmware and letting the SoC run on REF_CLK is fixing the problem. Corresponding firmware change is also needed to set the clock source once the target is initialized. Since 10.2.4 firmware is having this ROM patch, applying skip_clock_init only for 10.2.4 firmware versions. Signed-off-by:

In some cases some channel survey data was reported incorrect. Channel info events were expected to come in pairs without and with COMPLETE flag set respectively for each channel visit during scan. The known deviation from this is rule for last scan chan info and first (next) scan chan info both have COMPLETE flag set. This was either programmed with the intent of providing BSS cycle count info or this is an artefact of firmware scan state machine. Either way this is useless due to short wraparound time, wraparound quirks and no overflow notification. Survey dumps now include only data gathered during scan channel visits that can be computed correctly. This should improve hostapd ACS a little bit. Reported-by:

When QCA988X cycle counter HW register wraps around it resets to 0x7fffffff instead of 0. All other cycle counter related registers are divided by 2 so they never wraparound themselves. QCA61X4 has a uniform CC and it wraparounds in a regular fashion though. Worst case wraparound time is approx 24 seconds (2**31 / 88MHz). Since scan channel visit times are max 5 seconds (offchannel case) it is guaranteed there's been at most 1 wraparound and it is possible to compute survey active time value. It is, however, impossible to determine the point at which Rx Clear Count has been divided by two so it is not reported upon wraparound. This fixes some occasional incorrect survey data on QCA988X as some channels (depending on how/when scan/offchannel requests were requested) would have approx 24 sec active time which wasn't actually the case. This should improve hostapd ACS a little bit. Reported-by:

This patch implements sendpage support for AF_UNIX SOCK_STREAM sockets. This is also required for a complete splice implementation. The implementation is a bit tricky because we append to already existing skbs and so have to hold unix_sk->readlock to protect the reading side from either advancing UNIXCB.consumed or freeing the skb at the socket receive tail.

Or Gerlitz says: ==================== mlx4: Enable single ported VFs over IB ports This series further enhances the support for mlx4 single ported VFs introduced in 3.15 to work over IB ports too. Just as quick reminder, the ConnectX3 device family exposes one PCI device which serves both ports. This can be non-optimal under virtualization schemes where the admin would like the VF to expose one interface to the VM, etc. Since all the VF interaction with the firmware passes through the PF driver, we can emulate to the VF they have one port, and further create a set of the VFs which act on port1 of the device and another set which acts on port2. ==================== Signed-off-by: -

Or Gerlitz authored
Some VF drivers flow set the schedule queue in the QP context but without setting none of OPTPAR_SCHED_QUEUE or OPTPAR_PRIMARY_ADDR_PATH. To allow for such non-modified drivers to function as single ported IB VFs, we must adjust the schedule queue port whenever being set, e.g as currently done for single ported Eth VFs. Signed-off-by:

Or Gerlitz authored
As part of enabling single ported VFs over IB ports we need to handle some of the flows for generting EQ events for VFs which don't come into play under Eth ports. This mainly includes port management events derived from changes of the phyiscal port (lid change, client re-register, down/up, etc), VF pkey table changes and VF guid changes initiated by the IB driver. (1) make sure that events are generated only for VFs sitting on the relevant physical port (under the ALL_SLAVES flow). (2) before generating the event, convert from physical (one or two) to VF port (always equals one). Signed-off-by: -
Or Gerlitz authored
When multiplexling a MAD sent from VF, we should convert the port used by the guest to send the packet to the actual physical port which will be used to transmit the packet, before building the relevant address-handle (AH). This is needed under VPI for single ported VFs, since the code that builds the AH (mlx4_ib_query_ah()) makes decisions based on the input port. If we use the port number provided by the guest, it might have different protocol vs. the one this packat has to go from, and hence the result could be wrong. So far, the conversion was done after the AH was built and it worked for single ported Eth VFs which were not enabled under VPI. When adding support for single ported IB VFs and VPI, we hit that.

Or Gerlitz authored
Single port VFs always provide port = 1 (even if the actual physical port used is port 2). As such, we need to convert the port provided by the VF to the physical port before calling into the firmware. It turns out that the Linux mlx4 VF RoCE driver maintains a copy of the GID table and hence this change became critical only for single ported IB VFs, but it could be needed for other RoCE VF drivers too.
