Before sending a SESSION PROTECTION cmd the driver checks if the link_id indicated in the time event (and for which the cmd will be sent) is valid and exists. Clear the te_data::link_id when FW notifies that a session protection ended, so the check will actually fail when it should.

As described in IEEE sta 802.11-2020, table 9-30 (Address field contents), A-MSDU address 3 should contain the BSSID address. In TX_CMD we copy the MAC header from skb, and skb address 3 holds the destination address, but it may not be identical to the BSSID. Using the wrong destination address appears to work with (most) receivers without MLO, but in MLO some devices are checking for it carefully, perhaps as a consequence of link to MLD address translation. Replace address 3 in the TX_CMD MAC header with the correct address while retaining the skb address 3 unchanged. This ensures that skb address 3 will be utilized later for constructing the A-MSDU subframes. Note that we fill in the MLD address, but the firmware will do the necessary translation to link address after encryption. Signed-off-by:

This pointer can change here since the SKB can change, so we actually later open-coded IEEE80211_SKB_CB() again. Reload the pointer where needed, so the monitor-mode case using it gets fixed, and then use info-> later as well.

After commit e3eac9f3 ("wifi: cfg80211: Annotate struct cfg80211_scan_request with __counted_by"), the compiler may enforce dynamic array indexing of req->channels to stay below n_channels. As a result, n_channels needs to be increased _before_ accessing the newly added array index. Increment it first, then use "i" for the prior index.

Currently the driver exits eSR by calling iwl_mvm_esr_mode_inactive() before updating the FW (by deactivating one of the links), and therefore before sending the EML frame notifying that we are no longer in eSR. This is wrong for several reasons: 1. The driver sends SMPS activation frames when we are still in eSR and SMPS should be disabled when in eSR 2. The driver restores RLC configuration as it was before eSR entering, and RLC command shouldn't be sent in eSR Fix this by calling iwl_mvm_esr_mode_inactive() after FW update Fixes: 12bacfc2 ("wifi: iwlwifi: handle eSR transitions") Signed-off-by:

If a driver implements the change_interface() method, we switch interface type without taking the interface down, but still will recreate the debugfs for it since it's a new type.

As mentioned in the previous commit, we pretty quickly found that some APs have ECSA elements stuck in their probe response, so using that to not attempt to connect while CSA is happening we never connect to such an AP. Improve this situation by checking more carefully and ignoring the ECSA if cfg80211 has previously detected the ECSA element being stuck in the probe response. Additionally, allow connecting to an AP that's switching to a channel it's already using, unless it's using quiet mode. In this case, we may just have to adjust bandwidth later. If it's actually switching channels, it's better not to try to connect in the middle of that. Reported-by:

We recently added some validation that we don't try to connect to an AP that is currently in a channel switch process, since that might want the channel to be quiet or we might not be able to connect in time to hear the switching in a beacon. This was in commit c09c4f31 ("wifi: mac80211: don't connect to an AP while it's in a CSA process"). However, we promptly got a report that this caused new connection failures, and it turns out that the AP that we now cannot connect to is permanently advertising an extended channel switch announcement, even with quiet. The AP in question was an Asus RT-AC53, with firmware 3.0.0.4.380_10760-g21a5898. As a first step, attempt to detect that we're dealing with such a situation, so mac80211 can use this later.

When a wiphy work is queued with timer, and then again without a delay, it's started immediately but *also* started again after the timer expires. This can lead, for example, to warnings in mac80211's offchannel code as reported by Jouni. Running the same work twice isn't expected, of course.

The storage for the TLV PC register data wasn't done like all the other storage in the drv->fw area, which is cleared at the end of deallocation. Therefore, the freeing must also be done differently, explicitly NULL'ing it out after the free, since otherwise there's a nasty double-free bug here if a file fails to load after this has been parsed, and we get another free later (e.g. because no other file exists.) Fix that by adding the missing NULL assignment. Cc: stable@vger.kernel.org Fixes: 5e31b3df ("wifi: iwlwifi: dbg: print pc register data once fw dump occurred") Reported-by:
