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. Fix this by setting the A-MSDU bit before the offload bits. Fixes: 5e6a98dc ("iwlwifi: mvm: enable TCP/UDP checksum support for 9000 family") Reported-by:

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.)
