eSR is activated when a chanctx is assigned to more than one link. During eSR activation we should disable RLC for both phys, and configure the FW with a special phy command for both phys. Currently we assign the phy_ctxt to the link only after eSR activation, so RLC is not disabled for the new phy_ctxt, and a cmd is not sent to FW. Fix this by first assigning the new phy_ctxt to the link and then doing the eSR activation. Fixes: 12bacfc2 ("wifi: iwlwifi: handle eSR transitions") Reviewed-by:

The driver copies the userspace buffer into an internal NUL byte terminated buffer. While doing so, it was reading beyond the end of the userspace buffer, overwriting its own NUL termination in the process. Fix this by only copying the correct number of bytes.

Now with the mac80211 locking model changed, we no longer can cause any bad dependencies here between mvm->mutex and other mutexes in mac80211, so we no longer need to drop the mutex early or even temporarily. Clean this up. Signed-off-by:

If we want to drop packets, that's surely a good thing to do when we want to enter rfkill. Send this command despite rfkill so we can successfully clean up everything, we need to handle it separately since it has CMD_WANT_SKB, so it's not going to automatically return success when in rfkill.

The NVM_CHANNEL_ACTIVE bit means that active scanning/beaconing is allowed, however it's not an exact opposite of IEEE80211_CHAN_NO_IR. For example, NVM_CHANNEL_ACTIVE bit is not set on DFS channels, while cfg80211 doesn't really expect NO-IR on DFS channels. Signed-off-by:

During ieee80211_set_active_links() we do (among the others): 1. Call drv_change_vif_links() with both old_active and new_active 2. Unassign the chanctx for the removed link(s) (if any) 3. Assign chanctx to the added link(s) (if any) 4. Call drv_change_vif_links() with the new_active links bitmap The problem here is that during step #1 the driver doesn't know whether we will activate multiple links simultaneously or are just doing a link switch, so it can't check there if multiple links are supported/enabled. (Some of the drivers might enable/disable this option dynamically) And during step #3, in which the driver already knows that, returning an error code (for example when multiple links are not supported or disabled), will cause a warning, and we will still complete the transition to the new_active links. (It is hard to undo things in that stage, since we released channels etc.) Therefore add a driver callback to check if the desired new_active links will be supported by the driver or not. This callback will be called in the beginning of ieee80211_set_active_links() so we won't do anything before we are sure it is supported. Signed-off-by:

cfg80211_update_known_bss will always consume the passed IEs. As such, cfg80211_update_assoc_bss_entry also needs to always set the pointers to NULL so that no double free can occur. Note that hitting this would probably require being connected to a hidden BSS which is then doing a channel switch while also switching to be not hidden anymore at the same time. Signed-off-by:

cfg80211_bss_update is expected to consume the IEs that are passed into it in the temporary internal BSS. This did not happen in some error cases (which are also WARN_ON paths), so change the code to use a common label and use that everywhere. Signed-off-by:

This is a more of a cosmetic fix. The branch will only be taken if proberesp_ies is set, which implies that beacon_ies is not set unless we are connected to an AP that just did a channel switch. And, in that case we should have found the BSS in the internal storage to begin with. Signed-off-by:

When reporting the radiotap timestamp, the mactime field is usually unused, we take the data from the device_timestamp. However, there can be cases where the radiotap timestamp is better reported as a 64-bit value, so since the mactime is free, add a flag to support using the mactime as a 64-bit radiotap timestamp.

FCC-594280 D01 Section B.3 allows peer-to-peer and ad hoc devices to operate on DFS channels while they operate under the control of a concurrent DFS master. For example, it is possible to have a P2P GO on a DFS channel as long as BSS connection is active on the same channel. Allow such operation by adding additional regulatory flags to indicate DFS concurrent channels and capable devices. Add the required relaxations in DFS regulatory checks. Signed-off-by:

It is possible for the TX status report for the (Re)Association Request frame to be delayed long enough for the AP's (Re)Association Response frame to be received and processed before it. If that were to happen for a case where the AP rejects the association with indication to come back later, the association timeout and retry state should not be modified anymore with the TX status information that would be processed after this. Updating the association timeout in such a reverse order of events could result in shortening the timeouts for the association comeback mechanism and that could result in the association failing. Track whether we have already processed association rejection with comeback time and if so, skip the timeout and retry update on any following TX status report. Signed-off-by:
