wifi: iwlwifi: mld: always take beacon ies in link grading

2025-11-12T07:54:46Z

One of the factors of a link's grade is the channel load, which is calculated from the AP's bss load element. The current code takes this element from the beacon for an active link, and from bss->ies for an inactive link. bss->ies is set to either the beacon's ies or to the probe response ones, with preference to the probe response (meaning that if there was even one probe response, the ies of it will be stored in bss->ies and won't be overiden by the beacon ies). The probe response can be very old, i.e. from the connection time, where a beacon is updated before each link selection (which is triggered only after a passive scan). In such case, the bss load element in the probe response will not include the channel load caused by the STA, where the beacon will. This will cause the inactive link to always have a lower channel load, and therefore an higher grade than the active link's one. This causes repeated link switches, causing the throughput to drop. Fix this by always taking the ies from the beacon, as those are for sure new.

wifi: iwlwifi: mvm: fix beacon template/fixed rate

2025-11-12T07:54:46Z

During the development of the rate changes, I evidently made some changes that shouldn't have been there; beacon templates with rate_n_flags are only in old versions, so no changes to them should have been necessary, and evidently broke on some devices. This also would have broken fixed (injection) rates, it would seem. Restore the old handling of this.

wifi: iwlwifi: fix aux ROC time event iterator usage

2025-11-12T07:54:46Z

The list_for_each_entry() iterator must not be used outside the loop. Even though we break and check for NULL, doing so still violates kernel iteration rules and triggers Coccinelle's use_after_iter.cocci warning. Cache the matched entry in aux_roc_te and use it consistently after the loop. This follows iterator best practices, resolves the warning, and makes the code more maintainable.

wifi: iwlwifi: fix potential use after free in iwl_mld_remove_link()

2025-10-19T12:12:36Z

This code frees "link" by calling kfree_rcu(link, rcu_head) and then it dereferences "link" to get the "link->fw_id". Save the "link->fw_id" first to avoid a potential use after free.

wifi: iwlwifi: pcie: fix byte count table for some devices

2025-09-15T08:20:47Z

In my previous fix for this condition, I erroneously listed 9000 instead of 7000 family, when 7000/8000 were already using iwlmvm. Thus the condition ended up wrong, causing the issue I had fixed for older devices to suddenly appear on 7000/8000 family devices. Correct the condition accordingly.
