If NAN interface is created with NL80211_ATTR_SOCKET_OWNER, the socket that is used to create the interface is used for all NAN operations and reporting NAN events. However, it turns out that sending commands and receiving events on the same socket is not possible in a completely race-free way: If the socket buffer is overflowed by the events, the command response will not be sent. In that case the caller will block forever on recv. Using non-blocking socket for commands is more complicated and still the command response or ack may not be received. So, keep unicasting NAN events to the interface creator, but allow using a different socket for commands. Signed-off-by:

The driver used cfg80211_connect_result() which is basically a wrapper around cfg80211_connect_done() passing a subset of the information that can be passed. For upcoming functionality this is not sufficient so switching to use cfg80211_connect_done(). Reviewed-by:

When a station that's not associated sends a data frame (e.g. an NDP) hostapd will respond with a disassoc frame, telling it that it's not associated. The station might also not be authenticated, in which case there will not be a station entry for it, and as a result we need to accept such frames without a station.

When we get a non-STA frame to transmit in client mode, we try to use the IWL_MVM_DQA_BSS_CLIENT_QUEUE queue (queue #4). However, at this point, the queue might not be allocated at all, causing warnings. The scenario on which this happened was a race condition between mac80211 and our queue allocation work: * mac80211 sends auth * we stop mac80211 queues to allocate a hw queue * authentication is aborted * we allocate HW queue and start mac80211 queues * mac80211 removes station * mac80211 hands us the auth frame from the pending queue At this point, since mac80211 has already removed the station, we try to transmit the frame through this special non-station case on queue 4 anyway. In order to really use it properly, we'd have to again go through the hw queue allocation work, and attach it to a station, etc. In this case that isn't possible (there's no station anymore), but if this special case were needed, then we'd have to do it this way. However, the special case is documented to exist for TDLS, but can't trigger there because the TDLS setup frames etc. are normal to-DS frames going to the peer through the AP. Testing also confirms that this code path isn't triggered in TDLS. Therefore, remove the code path to avoid using an unused queue. The erroneous frame described above will still be transmitted on the AUX queue, but arguably that's a mac80211 problem, which will eventually be fixed by moving everything there to TXQs.

When going into suspend, the HW configuration for MSI-X will likely be lost. As a consequence, after waking up, all IRQ causes will be mapped to interrupt 0, and as a consequence we don't notice the interrupt because in most cases this is an interrupt for a queue, and getting it doesn't read the other cause registers.

When in non-DQA mode, mac80211 actually gets a pretty much perfect idea (in vif->hw_queue/cab_queue) of which queues we're using. But in DQA mode, this isn't true - nonetheless, we were adding all the queues, even the ones stations are using, to the queue allocation bitmap. Fix this, we should only add the queues we really are using in DQA mode: * IWL_MVM_OFFCHANNEL_QUEUE, as we use this in both modes * mvm->aux_queue, as we use this in both modes - mac80211 never really knows about it but we use it as a cookie internally, so can't reuse it * possibly the GCAST queue (cab_queue) * all the "queues" we told mac80211 about we were using on each interface (vif->hw_queue), these are entirely virtual in this mode Also add back the failure now when we can't allocate any more of these - now virtual - queues; this was skipped in DQA mode and would lead to having multiple ACs or even interfaces use the same queue number in mac80211 (10, since that's the limit), which would stop far too many queues if stopped.

There may be a difference between the mac80211 vif->cab_queue and mvmvif->cab_queue, particularly with TVQM. Make the code map this earlier, instead of first returning the mac80211 one again from iwl_mvm_get_ctrl_vif_queue(). Signed-off-by:

In the driver, we track which hardware queue is associated with which mac80211 "hw_queue", in order to be able to stop and wake it. When moving these bitmaps out of the queue_info structures, the type of the bitmap was erroneously changed from u32 to u8, presumably in order to save memory. Turns out that u32 isn't needed, because the highest queue we can ever tell mac80211 is always < 16, but a u16 definitely is needed, queues >=8 do happen. While at it, throw a BUILD_BUG_ON() into the place where we set the limit (mvm->first_agg_queue) and a warning when it actually gets put into the bitmap. The consequence of this bug is that full HW queues associated with such a too-high mac80211 number never stop higher layer queues when full, and thus would simply drop all packets that couldn't be enqueued to the hardware queue.

The code was intended to enable IP header checksumming on AMSDUs, but failed to really do so because the A-MSDU bit was set after all the checksumming bits, and thus checking for A-MSDU could never be true.

When hostapd adds a station, it does so before sending the association response frame, so that it can indicate the correct status code in the response. However, when this then fails, or the association response already is a reject for some other reason, then there's no station entry and thus no per-station management queue to send the response on and it must be sent on the probe response queue. The code should therefore not warn. In theory, we could check and warn if the status code is success, but that seems excessive, so just relax the check to allow any association response frames.

If the first frame on a given TID is received with seqno 0 and needed to be retransmitted, we erroneously drop it because the deduplication data is initialized to zero, and then comparing if (unlikely(ieee80211_has_retry(hdr->frame_control) && dup_data->last_seq[tid] == hdr->seq_ctrl && dup_data->last_sub_frame[tid] >= sub_frame_idx)) return true; will return in iwl_mvm_is_dup() since last_sub_frame is also set to zero, and sub_frame_idx is usually zero since this only covers the relatively rare case of A-MSDU. Fix this by initializing the last_seq array to 0xffff, which is an impossible value for hdr->seq_ctrl to have here because the lower four bits are the fragment number, and fragments aren't handled in this code but go to mac80211 instead.

In commit b93b1fe3 ("iwlwifi: mvm: fix init_dbg flow to work as expected"), the code was changed to make the stop conditional on not having failed (and on not having init_dbg), which doesn't make sense - we should stop the device regardless of failures. Failure to do so is leading to the device being enabled when it shouldn't be, and - if it gets re-enabled later - the new context info code gets confused as paging data wasn't freed. Remove the invalid error condition again. Fixes: b93b1fe3 ("iwlwifi: mvm: fix init_dbg flow to work as expected") Signed-off-by:

This appears to happen in some cases, like when iwlmvm is unloaded and loaded again without also unloading iwlwifi. Warn in this case and free the paging data to be able to continue without causing corruption and kernel crashes due to it (otherwise, paging data is overwritten, but dram->paging_cnt gets to be twice as big as it should be, and then an eventual free will crash.)
