2024-02-08wifi: mac80211: implement MLO multicast deduplicationJohannes Berg1-2/+20
If the vif is an MLD then it may receive multicast from different links, and should drop those frames according to the SN. Implement that. Link: https://msgid.link/20240129200456.693b77d14b44.I491846f2bea0058c14eab6422962c10bfae9b675@changeid Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2024-01-26wifi: mac80211: process and save negotiated TID to Link mapping requestAyala Beker1-0/+14
An MLD may send TID-to-Link mapping request frame to negotiate TID to link mapping with a peer MLD. Support handling negotiated TID-to-Link mapping request frame by parsing the frame, asking the driver whether it supports the received mapping or not, and sending a TID-to-Link mapping response to the AP MLD. Theoretically, links that became inactive due to the received TID-to-Link mapping request, can be selected to be activated but this would require tearing down the negotiated TID-to-Link mapping, which is still not supported.

When reporting the radiotap timestamp, the mactime field is usually unused, we take the data from the device_timestamp.

2023-03-22wifi: mac80211: mesh fast xmit supportFelix Fietkau1-1/+9
Previously, fast xmit only worked on interface types where initially a sta lookup is performed, and a cached header can be attached to the sta, requiring only some fields to be updated at runtime. This technique is not directly applicable for a mesh device type due to the dynamic nature of the topology and protocol. There are more addresses that need to be filled, and there is an extra header with a dynamic length based on the addressing mode. Change the code to cache entries contain a copy of the mesh subframe header + bridge tunnel header, as well as an embedded struct ieee80211_fast_tx, which contains the information for building the 802.11 header. Add a mesh specific early fast xmit call, which looks up a cached entry and adds only the mesh subframe header, before passing it over to the generic fast xmit code. To ensure the changes in network are reflected in these cached headers, flush affected cached entries on path changes, as well as other conditions that currently trigger a fast xmit check in other modes (key changes etc.) This code is loosely based on a previous implementation by: Sriram R <quic_srirrama@quicinc.com> Cc: Sriram R <quic_srirrama@quicinc.com> Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name> Link: https://lore.kernel.org/r/20230314095956.62085-4-nbd@nbd.name Signed-off-by: Johannes Berg <johannes.berg@intel.com>

When we have multiple interfaces receiving the same frame, such as a multicast frame, one interface might have a sta and the other not. In this case, link_sta would be set but not cleared again. Always set link_sta, so we keep an invariant that link_sta and sta are either both set or both not set. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2023-02-14wifi: mac80211: Fix for Rx fragmented action framesGilad Itzkovitch1-1/+2
The ieee80211_accept_frame() function performs a number of early checks to decide whether or not further processing needs to be done on a frame. One of those checks is the ieee80211_is_robust_mgmt_frame() function. It requires to peek into the frame payload, but because defragmentation does not occur until later on in the receive path, this peek is invalid for any fragment other than the first one. Also, in this scenario there is no STA and so the fragmented frame will be dropped later on in the process and will not reach the upper stack. This can happen with large action frames at low rates, for example, we see issues with DPP on S1G. This change will only check if the frame is robust if it's the first fragment. Invalid fragmented packets will be discarded later after defragmentation is completed.
