wifi: mac80211: fix qos on mesh interfaces

2023-03-30T10:51:39Z

commit 4e348c6c6e23491ae6eb5e077848a42d0562339c upstream. When ieee80211_select_queue is called for mesh, the sta pointer is usually NULL, since the nexthop is looked up much later in the tx path. Explicitly check for unicast address in that case in order to make qos work again.

wifi: mac80211: Drop support for TX push path

2022-10-10T09:06:14Z

All drivers are now using mac80211 internal queues (iTXQs). Drop mac80211 internal support for the old push path. Signed-off-by: Alexander Wetzel Signed-off-by: Johannes Berg

wifi: mac80211: wme: use ap_addr instead of deflink BSSID

2022-10-07T13:24:01Z

We use this to look up the destination station, so it needs to be the MLD address of the AP for an MLO; use ap_addr instead of the BSSID. Signed-off-by: Johannes Berg

wifi: mac80211: fix queue selection for mesh/OCB interfaces

2022-07-11T08:36:55Z

When using iTXQ, the code assumes that there is only one vif queue for broadcast packets, using the BE queue. Allowing non-BE queue marking violates that assumption and txq->ac == skb_queue_mapping is no longer guaranteed. This can cause issues with queue handling in the driver and also causes issues with the recent ATF change, resulting in an AQL underflow warning.

wifi: mac80211: reorg some iface data structs for MLD

2022-06-20T10:55:06Z

Start reorganizing interface related data structures toward MLD. The most complex part here is for the keys, since we have to split the various kinds of GTKs off to the link but still need to use (for WEP) the other keys as a fallback even for multicast frames. Signed-off-by: Johannes Berg

mac80211: drop check for DONT_REORDER in __ieee80211_select_queue

2021-11-15T09:55:40Z

When __ieee80211_select_queue is called, skb->cb has not been cleared yet, which means that info->control.flags can contain garbage. In some cases this leads to IEEE80211_TX_CTRL_DONT_REORDER being set, causing packets marked for other queues to randomly end up in BE instead. This flag only needs to be checked in ieee80211_select_queue_80211, since the radiotap parser is the only piece of code that sets it Fixes: 66d06c84730c ("mac80211: adhere to Tx control flag that prevents frame reordering") Cc: stable@vger.kernel.org Signed-off-by: Felix Fietkau Link: https://lore.kernel.org/r/20211110212201.35452-1-nbd@nbd.name Signed-off-by: Johannes Berg

mac80211: remove WDS-related code

2020-11-11T07:39:13Z

Now that all the mac80211-based drivers have removed WDS code and in particular the ability to advertise such devices, also remove all the code related to WDS here.

mac80211: don't overwrite QoS TID of injected frames

2020-11-06T10:02:42Z

Currently ieee80211_set_qos_hdr sets the QoS TID of all frames based on the value assigned to skb->priority. This means it will also overwrite the QoS TID of injected frames. The commit 753ffad3d624 ("mac80211: fix TID field in monitor mode transmit") prevented injected frames from being modified because of this by setting skb->priority to the TID of the injected frame, which assured the QoS TID will not be changed to a different value. Unfortunately, this workaround complicates the handling of injected frames because we can't set skb->priority without affecting the TID value in the QoS field of injected frames. To avoid this, and to simplify the next patch, detect if a frame is injected in ieee80211_set_qos_hdr and if so do not change its QoS field.

mac80211: adhere to Tx control flag that prevents frame reordering

2020-11-06T10:01:53Z

When the Tx control flag is set to prevent frame reordering, send all frames that have this flag set on the same queue. This assures that frames that have this flag set are not reordered relative to other frames that have this flag set.
