2022-04-12ath9k: fix ath_get_rate_txpower() to respect the rate list end tagPeter Seiderer
Stop reading (and copying) from ieee80211_tx_rate to ath_tx_info.rates after list end tag (count == 0, idx < 0), prevents copying of garbage to card registers. Note: no need to write to the remaining ath_tx_info.rates entries as the complete ath_tx_info struct is already initialized to zero from both call sites.

2022-04-12net: remove noblock parameter from recvmsg() entitiesOliver Hartkopp
The internal recvmsg() functions have two parameters 'flags' and 'noblock' that were merged inside skb_recv_datagram(). As a follow up patch to commit f4b41f062c42 ("net: remove noblock parameter from skb_recv_datagram()") this patch removes the separate 'noblock' parameter for recvmsg(). Analogue to the referenced patch for skb_recv_datagram() the 'flags' and 'noblock' parameters are unnecessarily split up with e.g. err = sk->sk_prot->recvmsg(sk, msg, size, flags & MSG_DONTWAIT, flags & ~MSG_DONTWAIT, &addr_len); or in err = INDIRECT_CALL_2(sk->sk_prot->recvmsg, tcp_recvmsg, udp_recvmsg, sk, msg, size, flags & MSG_DONTWAIT, flags & ~MSG_DONTWAIT, &addr_len); instead of simply using only flags all the time and check for MSG_DONTWAIT where needed (to preserve for the formerly separated no(n)block condition).

When using an external PHY connected using RGMII to mt7531 port 5, the PHY can be used to used support 1000BASE-X connections. Moreover, if 1000BASE-T is supported, then we should allow 1000BASE-X as well, since which are supported is a property of the PHY. Therefore, it makes no sense to exclude this from the linkmodes when 1000BASE-T is supported.

2022-04-11net: lan966x: Add FDMA functionalityHoratiu Vultur
Ethernet frames can be extracted or injected to or from the device's DDR memory. There is one channel for injection and one channel for extraction. Each of these channels contain a linked list of DCBs which contains DB. The DCB contains only 1 DB for both the injection and extraction. Each DB contains a frame. Every time when a frame is received or transmitted an interrupt is generated. It is not possible to use both the FDMA and the manual injection/extraction of the frames. Therefore the FDMA has priority over the manual because of better performance values.

2022-04-11net: macb: Restart tx only if queue pointer is laggingTomas Melin
commit 4298388574da ("net: macb: restart tx after tx used bit read") added support for restarting transmission. Restarting tx does not work in case controller asserts TXUBR interrupt and TQBP is already at the end of the tx queue. In that situation, restarting tx will immediately cause assertion of another TXUBR interrupt. The driver will end up in an infinite interrupt loop which it cannot break out of. For cases where TQBP is at the end of the tx queue, instead only clear TX_USED interrupt. As more data gets pushed to the queue, transmission will resume. This issue was observed on a Xilinx Zynq-7000 based board. During stress test of the network interface, driver would get stuck on interrupt loop within seconds or minutes causing CPU to stall.

2022-04-11mac80211: prepare sta handling for MLO supportSriram R
Currently in mac80211 each STA object is represented using sta_info datastructure with the associated STA specific information and drivers access ieee80211_sta part of it. With MLO (Multi Link Operation) support being added in 802.11be standard, though the association is logically with a single Multi Link capable STA, at the physical level communication can happen via different advertised links (uniquely identified by Channel, operating class, BSSID) and hence the need to handle multiple link STA parameters within a composite sta_info object called the MLD STA. The different link STA part of MLD STA are identified using the link address which can be same or different as the MLD STA address and unique link id based on the link vif. To support extension of such a model, the sta_info datastructure is modified to hold multiple link STA objects with link specific params currently within sta_info moved to this new structure. Similarly this is done for ieee80211_sta as well which will be accessed within mac80211 as well as by drivers, hence trivial driver changes are expected to support this. For current non MLO supported drivers, only one link STA is present and link information is accessed via 'deflink' member. For MLO drivers, we still need to define the APIs etc. to get the correct link ID and access the correct part of the station info. Currently in mac80211, all link STA info are accessed directly via deflink. These will be updated to access via link pointers indexed by link id with MLO support patches, with link id being 0 for non MLO supported cases. Except for couple of macro related changes, below spatch takes care of updating mac80211 and driver code to access to the link STA info via deflink. @ieee80211_sta@ struct ieee80211_sta *s; struct sta_info *si; identifier var = {supp_rates, ht_cap, vht_cap, he_cap, he_6ghz_capa, eht_cap, rx_nss, bandwidth, txpwr}; @@ ( s-> - var + deflink.var | si->sta. - var + deflink.var ) @sta_info@ struct sta_info *si; identifier var = {gtk, pcpu_rx_stats, rx_stats, rx_stats_avg, status_stats, tx_stats, cur_max_bandwidth}; @@ ( si-> - var + deflink.var ) Signed-off-by: Sriram R <quic_srirrama@quicinc.com> Link: https://lore.kernel.org/r/1649086883-13246-1-git-send-email-quic_srirrama@quicinc.com [remove MLO-drivers notes from commit message, not clear yet; run spatch] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-04-11mac80211: introduce BSS color collision detectionLorenzo Bianconi
Add ieee80211_rx_check_bss_color_collision routine in order to introduce BSS color collision detection in mac80211 if it is not supported in HW/FW (e.g. for mt7915 chipset). Add IEEE80211_HW_DETECTS_COLOR_COLLISION flag to let the driver notify BSS color collision detection is supported in HW/FW. Set this for ath11k which apparently didn't need this code.

Since commit 1771afd47430 ("net: cpsw: avoid alignment faults by taking NET_IP_ALIGN into account") the TI CPSW driver was switched to use correct define CPSW_HEADROOM_NA to avoid alignment faults, but there are two places left where CPSW_HEADROOM is still used (without causing issues). Hence, completely drop CPSW_HEADROOM define and use CPSW_HEADROOM_NA everywhere to avoid further mistakes in code. Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S.

2022-04-11net: ethernet: stmmac: fix altr_tse_pcs function when using a fixed-linkDinh Nguyen
When using a fixed-link, the altr_tse_pcs driver crashes due to null-pointer dereference as no phy_device is provided to tse_pcs_fix_mac_speed function. Fix this by adding a check for phy_dev before calling the tse_pcs_fix_mac_speed() function. Also clean up the tse_pcs_fix_mac_speed function a bit. There is no need to check for splitter_base and sgmii_adapter_base because the driver will fail if these 2 variables are not derived from the device tree.
