Add support CSA countdown offloading. When CSA starts, the driver specifies the offsets to the eCSA and CSA IEs in the beacon template command and the fw performs the countdown. The fw notifies the driver when the channel switch flow should be performed. Beacon sent notifications are not used anymore.

Currently code allows mvm reference to become negative and only warns in case mvm reference is released while reference counting is 0. However, we better prevent this from happening at all since iwl_mvm_unref() may race against iwl_mvm_unref_all_except() which is called on restart. As a result we might get the same reference unreferenced twice ending with a negative value: An example for an easily reproduced log: [ 2689.909166] iwl_mvm_ref Take mvm reference - type 8 [ 2690.732716] iwl_mvm_unref_all_except Cleanup: remove mvm ref type 8 (1) [ 2690.849708] iwl_mvm_unref Leave mvm reference - type 8 [ 2690.849721] WARNING: ... iwl_mvm_unref+0xb0/0xc0 [iwlmvm]() If there will be yet another another restart iwl_mvm_unref_all_except will run from 0 up to ref count, and since it is unsigned, we will throw the transport ref count completely out of balance: iwl_mvm_unref_all_except[I] -- Cleanup: remove mvm ref type 8 (255) iwl_trans_slv_unref[I] -- rpm counter: 0 iwl_trans_slv_unref[I] -- rpm counter: -1 iwl_trans_slv_unref[I] -- rpm counter: -2 ... iwl_trans_slv_unref[I] -- rpm counter: -253 iwl_trans_slv_unref[I] -- rpm counter: -254 As there is no valid scenario where we can get to a negative reference count - prevent it from happening.

Next hardware will direct packets to core based on the TCP/UDP streams. This logic can create holes in reorder buffer since packets that belong to other stream were directed to a different core. However, those are valid holes and the packets can be indicated in L3 order. The hardware will utilize a mechanism of informing the driver of the normalized ssn and the driver shall release all packets that SN is lower than the nssn. This enables managing the reorder across the queues without sharing any data between them. The reorder buffer is allocated and released directly in the RX path in order to avoid various races between control path and rx path. The code utilizes the internal messaging to notify rx queues of when to delete the reorder buffer.

According to the spec when a BA session is started there is a timeout set for the session in the ADDBA request. If there is not activity on the TA/TID then the session expires and a DELBA is sent. In order to check for the timeout, data must be shared among the rx queues. Add a timer that runs as long as BA session is active for the station and stops aggregation session if needed. This patch also lays the infrastructure for the reordering buffer which will be enabled in the next patches.

mac80211 will call the driver whenever there is a race between RSS queues and control path that requires a processing of all pending frames in RSS queues. Implement that by utilizing the internal notification mechanism: queue a message to all queues. When the message is received on a queue it decrements the atomic counter. This guarantees that all pending frames in the RX queue were processed since the message is in order inside the queue.

"DQA" is shorthand for "dynamic queue allocation". This enables on-demand allocation of queues per RA/TID rather than statically allocating per vif, thus allowing a potential benefit of various factors. Please refer to the DOC section this patch adds to sta.h to see a more in-depth explanation of this feature. There are many things to take into consideration when working in DQA mode, and this patch is only one in a series. Note that default operation mode is non-DQA mode, unless the FW indicates that it supports DQA mode. This patch enables support of DQA for a station connected to an AP, and works in a non-aggregated mode. When a frame for an unused RA/TID arrives at the driver, it isn't TXed immediately, but deferred first until a suitable queue is first allocated for it, and then TXed by a worker that both allocates the queues and TXes deferred traffic. When a STA is removed, its queues goes back into the queue pools for reuse as needed.

LQM stands for Link Quality Measurement. The firmware will collect a defined set of statitics (see the notification for details) that allow to know how busy the medium is. The driver issues a request to the firmware that includes the duration of the measurement (the firmware needs to be on channel for that amount of time) and the timeout (in case the firmware has a lot of offchannel activities). If the timeout elapses, the firmware will send partial results which are still valuable. In case of disassociation / channel switch and alike, the driver is in charge of stopping the measurements and the firmware will reply with partial results. The user space API for now is debugfs only and will be implmemented in an upcoming patch.

The firmware/hardware only supports checking AES-CMAC on RX, not using it on TX. For station mode this is fine, since it's the only thing it will ever do. For AP mode, it never receives such frames, but must be able to transmit them. This is currently broken since we try to enable them for hardware crypto (for RX only) and then treat them as TX_CMD_SEC_EXT, leading to FIFO underruns during TX so the frames never go out to the air. To fix this, simply use software on TX in AP (and IBSS) mode. Signed-off-by: NJohannes Berg <johannes.berg@intel.com> Signed-off-by: NEmmanuel Grumbach <emmanuel.grumbach@intel.com>

If we heard a beacon before starting association, this order is maintained and ba is properly set. However, if the first beacon is received after association, we send the power command upon association, configure the beacon filtering when the first beacon arrives, and in that case, beacon abort is not set.

If protocol offloading is configured, the fw might generate some frames (e.g. arp response) on its own during d3/d0i3. On d3/d0i3 exit the driver queries the updated PN (if relevant), and updates its keys (for the d0i3 case, this is done by iwl_mvm_d0i3_exit_work(), which is scheduled on d0i3 exit) While in d0i3, iwlmvm defers tx frames until d0i3 exit, and then continues their processing. This is problematic with TKIP, since the frame's PN has already been set at this stage (in contrast to CCMP, where the PN is being set only later on), so both the frame's PN and the upcoming PN update (from d0i3 exit work) might be wrong. Fix it by moving the TX PN assignment (for TKIP) to the driver, similarly to CCMP.

As we're working on multi-queue RX, we want to parallelise checking the PN in order to avoid having to serialise the RX processing. It may seem that doing parallel PN checking is insecure, but it turns out to be OK because queue assignment is done based on the data in the frame (IP/TCP) and thus cannot be manipulated by an attacker, since the data is encrypted and must first have been decrypted successfully. There are some corner cases, in particular when the peer starts using fragmentation which redirects the packet to the default queue. However this redirection is remembered (for the STA, per TID) and thus cannot be exploited by an attacker either. Leave checking on the default queue (queue 0) to mac80211, since we get fragmented packets there and those are subject to stricter checks during reassembly.

The d0i3_mode variable is used to distinguish between transports that handle d0i3 entry during suspend by themselves (i.e. the slave transports) and those which rely on the op_mode layer to do it. The reason why the former do it by themselves is that they need to transition from d0i3 in runtime_suspend into d0i3 in system-wide suspend and this transition needs to happen before the op_mode's suspend flow is called. The wowlan_d0i3 element is also a bit confusing, because it just reflects the wowlan->any value for the trans to understand. This is a bit unclear in the code and not generic enough for future use. To make it clearer and to generalize the platform power mode settings, introduce two variables to indicate the platform power management modes used by the transport. Additionally, in order not to take too big a step in one patch, treat this new variables semantically in the same way as the old d0i3_mode element, introducing a iwl_mvm_enter_d0i3_on_suspend() function to help with that. This commit also adds the foundation for a new concept where the firmware configuration state (i.e. D0, D3 or D0i3) is abstracted from the platform PM mode we are in (i.e. runtime suspend or system-wide suspend).
