2024-04-19wifi: mac80211: handle link ID during management TxSriram R
During non-STA management Tx, when source address is same as one of the link addresses and even when userspace requested Tx on a specific link, the link ID is not set in the TX control information. Now if the MLD address is also the same as that of the link address, then mac80211 fills link as "unspecified", since it looks like MLD TX. This is unexpected, however, since non-STA TX must specify which link to use. In hwsim, this will (after warnings) result in dropping such frames as well. Use and set the link id if the link bss is matching the address and requested channel.

2024-04-19wifi: mac80211: handle sdata->u.ap.active flag with MLOAditya Kumar Singh
Currently whenever link AP beacon is assigned, sdata->u.ap.active flag is set and whenever it is brought down, the flag is reset. However, with MLO, all the links of the same MLD would use the same sdata. Hence there is no need to set/reset for each link up/down. Also, resetting it when only one of the links went down is not desirable. Add changes to set the active flag only when first link is assigned beacon. Similarly, add changes to reset that flag only when last link is brought down.

2024-04-19wifi: mac80211: keep mac80211 consistent on link activation failureBenjamin Berg
In the unlikely event that link_use_channel fails while activating a link, mac80211 would go into a bad state. Unfortunately, we cannot completely avoid failures from drivers in this case. However, what we can do is to just continue internally anyway and assume the driver is going to trigger a recovery flow from its side. Doing that means that we at least have a consistent state in mac80211 allowing such a recovery flow to succeed.

2024-04-19wifi: mac80211: reserve chanctx during findJohannes Berg
When searching for a chanctx for re-use, it's later adjusted and assigned. It may also be that another one is already assigned to the link in question, so unassign can also happen. In short, the driver is called multiple times. During these callbacks, it may thus change active links (on another interface), which then can in turn cause the found chanctx (that's going to be reused) to get removed and freed. To avoid this, temporarily assign it to the reserved chanctx and track the link that wants to use it in the reserved_links list. This causes the ieee80211_chanctx_refcount() to be increased by one during these operations, thus avoiding the free.

To mitigate this, introduce the EMLSR prevention mechanism, which operates as follows: - On each exit from EMLSR event, record the timestamp and the exit reason. - If two consecutive exits happen for the same reason within a 400-second window, enforce a 300-second EMLSR prevention. - If a third exit for the same reason occurs within 400 seconds from the second exit, enforce an extended EMLSR prevention of 600 seconds.

For selecting what link(s) out of the usable ones to activate, calculate a grade for a given link. Calculation of a link grade is done as follows: 1. get the estimated throughput according to the RSSI of the link, this will be the base grade 2. get the channel load from the BSS Load Element, subtracting the load caused by us. Apply the factor on the grade. 3. puncturing factor: calculate the percentage of the punctured subchannels (out of the total subchannels). Apply this on the grade. The link grading will be used by the link selection mechanism in a later patch. Also add KUnit tests for it.

Instead of setting the UID to type mapping while building the scan command, set the UID to type mapping only after the scan request command was sent successfully. This resolves a bug where in case a scan request command fails and a recovery flow is initiated, the recovery flow would indicate to mac80211 that scan is completed though it was not really started.

2024-04-19wifi: mac80211: transmit deauth only if link is availableJohannes Berg
There's an issue in that when we disconnect from an AP due to the AP switching to an unsupported channel, we might not tell the driver about this before we try to send the deauth. If the underlying implementation has detected the quiet CSA, this may cause issues if this is the only active link. Avoid this by transmitting (and flushing) the deauth only when there's an active link available that's not affected by quiet CSA. Since this introduces link->u.mgd.csa_blocked_tx and we no longer check sdata->csa_blocked_tx for the TX itself also rename the latter to csa_blocked_queues.

The AP removal timer field need not be aligned, so the code shouldn't access it directly, but use unaligned loads. Use get_unaligned_le16(), which even is shorter than the current code since it doesn't need a cast.
