mac80211 added a new callback to add a vif debugfs. Implement it instead of adding the debugfs directly, which will make it properly preserved over switching the vif from non-MLD/MLD and back. This requires some rework so that we still have the symlink but trust mac80211 to add/remove the debugfs. Signed-off-by:

YoYo introduces 2 new region types: prph mac and phy blocks. The data in this regions consists of a list of (base address, size) pairs. This way we can set a block of consecutive registers by the base address and the size, instead of a list of registers. Add support for parsing and dumping these new region types Signed-off-by:

YoYo (debug data collection mechanism) is introducing 2 new types of regions: prph mac/phy ranges. These types will have a common logic of reading the data from the device as the mac/phy prph has. Put it in a separate function so it can be reused. Signed-off-by:

As we are moving to MLO and links terms, also the airtime protection will be done for a link rather than for a vif. Thus, some drivers will need to know for which link to protect airtime. Add link id as a parameter to the mgd_prepare_tx() callback. Signed-off-by:

If there is a disassoc before the fisrt beacon we need to protect a session for the deauth frame. Currently we are checking if we had a beacon in the default link, which is wrong in a MLO connection and link id != 0. Fix this by checking all the active links, if none had a beacon then protect a session. If at least one link had a beacon there is no need for session protection. Signed-off-by:

When the station is marked as no longer authorized, we shouldn't transmit to it any longer, but in particular we shouldn't be able to transmit to it after removing keys, which might lead to frames being sent out unencrypted depending on the exact hardware offload mechanism. Thus, instead of flushing only on station destruction, which covers only some cases, always flush on unauthorization. Signed-off-by:

When this flow is invoked with the "drop" parameter as true, we only drop the frames from the hw queues, but not from the sw queues. So when we call wake_queues() after hw queue purging, all the frames from the sw queues will be TX'ed, when what we actually want to do is to purge all queues in order to not TX anything... This can cause, for example, TXing data frames to the peer after the deauth frame was sent. Fix this by purging the sw queues in addition to the hw queues if the drop parameter is true.

When the remain on channel is removed at the time it should have expired, we have a race: the driver could be handling the flow of the expiration while mac80211 is cancelling that very same remain on channel request. This wouldn't be problem in itself, but since mac80211 can send the next request to the driver in the cancellation flow, we can get to the following situation: CPU0 CPU1 expiration of roc in driver ieee80211_remain_on_channel_expired() Cancellation of the roc schedules a worker (hw_roc_done) Add next roc hw_roc_done_wk runs and ends the second roc prematurely. Since, by design, there is only one single request sent to the driver at a time, we can safely assume that after the cancel() request returns from the driver, we should not handle any worker that handles the expiration of the request. Cancel the hw_roc_done worker after the cancellation to make sure we start the next one with a clean slate. Signed-off-by:Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by:

When the scan parameters for a 6GHz scan specify a unicast BSSID address, and the corresponding AP is found in the scan list, add a corresponding entry in the collocated AP list, so this AP would be directly probed even if it was not advertised as a collocated AP. This is needed for handling a scan request that is intended for a ML probe flow, where user space can requests a scan to retrieve information for other links in the AP MLD. Signed-off-by:

EMLSR operation and SMPS operation cannot coexist. Thus, when EMLSR is enabled, all SMPS signaling towards the AP should be stopped (it is expected that the AP will consider SMPS to be off). Rename IEEE80211_VIF_DISABLE_SMPS_OVERRIDE to IEEE80211_VIF_EML_ACTIVE and use the flag as an indication from the driver that EMLSR is enabled. When EMLSR is enabled SMPS flows towards the AP MLD should be stopped. Signed-off-by:

In MLO, we have a per-link debugfs directory which contains the per-link files. In case of non-MLO we would like to put the per-link files in the netdev directory to keep it how it was before MLO. - Upon interface creation the netdev will be created with the per-link files in it. - Upon switching to MLO: delete the entire netdev directory and then recreate it without the per-link files. Then the per-link directories with the per-link files in it will be created in ieee80211_link_init() - Upon switching to non-MLO: delete the entire netdev directory (including the per-link directories) and recreate it with the per-link files in it. Note that this also aligns to always call the vif link debugfs method for the deflink as promised in the documentation, which wasn't done before. Signed-off-by:

Add a callback which the driver can use to add the vif debugfs. We used to have this back until commit d260ff12 ("mac80211: remove vif debugfs driver callbacks") where we thought that it will be easier to just add them during interface add/remove. However, now with multi-link, we want to have proper debugfs for drivers for multi-link where some files might be in the netdev for non-MLO connections, and in the links for MLO ones, so we need to do some reconstruction when switching the mode. Moving to this new call enables that and MLO drivers will have to use it for proper debugfs operation. Signed-off-by:

If the association command fails then the authentication is still valid and it makes sense to keep it alive. Otherwise, we would currently get into an inconsistent state because mac80211 on the one hand is disconnected but on the other hand the state is not entirely cleared and a new authentication could not continue.

We don't (yet) send the IGTK down to the firmware, but when we do it needs to be with the broadcast station ID, not the multicast station ID.

Johannes Berg authored
We can't really know easily if a BIGTK will be used, but in case firmware supports BIGTK it also supports the very easy IGTK use (nothing to do on the host), and requires that we program both IGTK and BIGTK to be able to use the BIGTK. Thus, change the condition here to set the keys in firmware (both IGTK/BIGTK) if BIGTK is supported. Signed-off-by:

There's a race when the device is unbound (maybe because the module is unloaded) while the opmode start hasn't finished yet. The complete(request_firmware_complete) after the opmode start was meant (and commented accordingly) to prevent this problem, but it's not sufficient when the opmode module is loaded after the firmware load already completed, which happens regularly now because firmware load doesn't require userspace, unlike module load. Fix this by using the existing opmode registration mutex to protected the start/stop flows against each other properly. Signed-off-by:

The management frames protection flag is always set when the station is not yet authorized. However, it was not cleared after association even if the association did not use MFP. As a result, all public action frames are not parsed by fw (which will cause FTM to fail, for example). Update the station MFP flag after the station is authorized.

DCFO tracking compensate the CFO (carrier frequency offset) by digital hardware that provides fine CFO estimation. Although the avg_cfo which is a coarse information becomes zero, still we need DCFO tracking to compensate the residual CFO. However, the original flow skips the case when avg_cfo is zero, so we fix it to have expected performance. Signed-off-by:
