2024-12-04wifi: cfg80211: send MLO links tx power info in GET_INTERFACERameshkumar Sundaram
Currently, TX power is reported on interface/wdev level as part of NL80211_CMD_GET_INTERFACE. With MLO, Multiple links can be part of an interface/wdev and hence its necessary to report the TX power of each link. Add support to send tx power for all valid links of an MLD as part of NL80211_CMD_GET_INTERFACE request. As far as userspace is concerned, there is no behavioral change for Non-ML Interfaces.

2024-12-03wifi: mac80211: fix a queue stall in certain cases of CSAEmmanuel Grumbach
If we got an unprotected action frame with CSA and then we heard the beacon with the CSA IE, we'll block the queues with the CSA reason twice. Since this reason is refcounted, we won't wake up the queues since we wake them up only once and the ref count will never reach 0. This led to blocked queues that prevented any activity (even disconnection wouldn't reset the queue state and the only way to recover would be to reload the kernel module. Fix this by not refcounting the CSA reason. It becomes now pointless to maintain the csa_blocked_queues state. Remove it.

2024-11-30wifi: ath12k: introduce QMI firmware ready flagKarthikeyan Periyasamy
When hardware device group abstraction is introduced, the QMI firmware ready event of different devices in a group can be received simultaneously.

2024-11-30wifi: ath12k: Refactor core startupKarthikeyan Periyasamy
In the upcoming hardware device group abstraction radios across different devices can be grouped together to support multi-link operation and register as a device group to mac80211. Currently, ath12k_mac_allocate() and ath12k_mac_register() are part of ath12k_core_start() and ath12k_core_pdev_create() respectively and are based on per device (struct ath12k_base).

2024-11-29wifi: ath12k: defer vdev creation for MLORameshkumar Sundaram
Currently for single radio devices (ah->num_radio == 1) ath12k_mac_op_add_interface() creates vdev and later hw scan and assign_vif_chanctx uses the same. For MLO, vdev create request should carry ML address which will not be known during ath12k_mac_op_add_interface() as vif will be marked as ML only after links are added to it. If hw scan is requested, the vdev will be deleted post hw scan and subsequent assign_vif_chanctx call will create new vdev with ML address. But in certain cases assign_vif_chanctx could be called without any prior hw scan request and reusing the previously created vdev causes a non-ML vdev to be used for an ML vif and firmware operates the vdev in non-ML mode. Fix this by deferring vdev creation for interface until hw scan or assign_vif_chanctx request is received from mac80211.

2024-11-29wifi: ath12k: do not return invalid link id for scan linkSriram R
When a scan request is received, driver selects a link id for which the arvif can be mapped. Same link is also used for getting the link conf address. Currently, we return 0 as link id for a non ML vif, which is correct since that is the default link id. Also when any of the link vif is active and the scan request is for a channel in the active link we return its link id. But, when we don't hit both of the above cases (i.e not a ML vif or no active link vif for the channel is present) we currently return 0 as the link id. Bu the problemis that this might not work out always, eg., when only one link (eg. linkid = 1) is added to vif, then we won't find any link conf for link id 0 in the vif resulting in scan failure. During AP bringup, such scan failure causes bringup issues. Hence avoid sending link id 0 as default. Rather use a default link for scan and default link address for the same. This scan vdev will either be deleted if another scan is requested on same vif or when AP is broughtup on same link or during interface cleanup.

After FW v0.35.46.0, for AP mode, RTL8922A FW supports a new FW feature, called NOTIFY_AP_INFO, to notify driver information related to AP mode. And, one function of it is to monitor PS states of remote stations. Once one of them changes, FW will send a C2H event to tell driver. With this FW feature, we can declare AP_LINK_PS. For now, driver still needs to determine if a frame is ps-poll or U-APSD trigger. So, add the corresponding RX handling in driver, which activates only when at least one AP is running.

Retain a reference to the pci_bus for the lifetime of a pci_slot to avoid a use-after-free when the thunderbolt driver resets USB4 host routers on boot, causing hotplug remove/add of downstream docks or other devices (Lukas Wunner) - Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test (Guilherme Giacomo Simoes) - Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET) - Use pci_bus_read_dev_vendor_id() instead of hand-coded presence detection in cpqphp (Ilpo Järvinen) - Simplify cpqphp enumeration, which is already simple-minded and doesn't handle devices below hot-added bridges (Ilpo Järvinen) Virtualization: - Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS capability but do isolate functions as though PCI_ACS_RR and PCI_ACS_CR were set, so the functions can be in independent IOMMU groups (Mengyuan Lou) TLP Processing Hints (TPH): - Add and document TLP Processing Hints (TPH) support so drivers can enable and disable TPH and the kernel can save/restore TPH configuration (Wei Huang) - Add TPH Steering Tag support so drivers can retrieve Steering Tag values associated with specific CPUs via an ACPI _DSM to improve performance by directing DMA writes closer to their consumers (Wei Huang) Data Object Exchange (DOE): - Wait up to 1 second for DOE Busy bit to clear before writing a request to the mailbox to avoid failures if the mailbox is still busy from a previous transfer (Gregory Price) Endpoint framework: - Skip attempts to allocate from endpoint controller memory window if the requested size is larger than the window (Damien Le Moal) -

Currently mac80211's struct ieee80211_sta deflink is used to fetch any sta related configurations in driver. With MLO multiple link sta's (struct ieee80211_link_sta) are affiliated to an ML sta and corresponding link configs are present in sta->link[]. Fetch link sta of corresponding link from ML sta and use the same for configurations. Add ath12k_mac_get_link_sta() helper to fetch ieee80211_link_sta from arsta. But as ath12k_mac_op_sta_rc_update() is called in atomic context the helper cannot be used and instead rcu_dereference() has to be called directly.

2024-11-21Merge tag 'net-next-6.13' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "The most significant set of changes is the per netns RTNL. The new behavior is disabled by default, regression risk should be contained. Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its default value from PTP_1588_CLOCK_KVM, as the first is intended to be a more reliable replacement for the latter. Core: - Started a very large, in-progress, effort to make the RTNL lock scope per network-namespace, thus reducing the lock contention significantly in the containerized use-case, comprising: - RCU-ified some relevant slices of the FIB control path - introduce basic per netns locking helpers - namespacified the IPv4 address hash table - remove rtnl_register{,_module}() in favour of rtnl_register_many() - refactor rtnl_{new,del,set}link() moving as much validation as possible out of RTNL lock - convert all phonet doit() and dumpit() handlers to RCU - convert IPv4 addresses manipulation to per-netns RTNL - convert virtual interface creation to per-netns RTNL the per-netns lock infrastructure is guarded by the CONFIG_DEBUG_NET_SMALL_RTNL knob, disabled by default ad interim. - Introduce NAPI suspension, to efficiently switching between busy polling (NAPI processing suspended) and normal processing. - Migrate the IPv4 routing input, output and control path from direct ToS usage to DSCP macros. This is a work in progress to make ECN handling consistent and reliable. - Add drop reasons support to the IPv4 rotue input path, allowing better introspection in case of packets drop. - Make FIB seqnum lockless, dropping RTNL protection for read access. - Make inet{,v6} addresses hashing less predicable. - Allow providing timestamp OPT_ID via cmsg, to correlate TX packets and timestamps Things we sprinkled into general kernel code: - Add small file operations for debugfs, to reduce the struct ops size. - Refactoring and optimization for the implementation of page_frag API, This is a preparatory work to consolidate the page_frag implementation. Netfilter: - Optimize set element transactions to reduce memory consumption - Extended netlink error reporting for attribute parser failure. - Make legacy xtables configs user selectable, giving users the option to configure iptables without enabling any other config. - Address a lot of false-positive RCU issues, pointed by recent CI improvements. BPF: - Put xsk sockets on a struct diet and add various cleanups. Overall, this helps to bump performance by 12% for some workloads. - Extend BPF selftests to increase coverage of XDP features in combination with BPF cpumap. - Optimize and homogenize bpf_csum_diff helper for all archs and also add a batch of new BPF selftests for it. - Extend netkit with an option to delegate skb->{mark,priority} scrubbing to its BPF program. - Make the bpf_get_netns_cookie() helper available also to tc(x) BPF programs. Protocols: - Introduces 4-tuple hash for connected udp sockets, speeding-up significantly connected sockets lookup. - Add a fastpath for some TCP timers that usually expires after close, the socket lock contention. - Add inbound and outbound xfrm state caches to speed up state lookups. - Avoid sending MPTCP advertisements on stale subflows, reducing risks on loosing them. - Make neighbours table flushing more scalable, maintaining per device neigh lists. Driver API: - Introduce a unified interface to configure transmission H/W shaping, and expose it to user-space via generic-netlink. - Add support for per-NAPI config via netlink. This makes napi configuration persistent across queues removal and re-creation. Requires driver updates, currently supported drivers are: nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice. - Add ethtool support for writing SFP / PHY firmware blocks. - Track RSS context allocation from ethtool core. - Implement support for mirroring to DSA CPU port, via TC mirror offload. - Consolidate FDB updates notification, to avoid duplicates on device-specific entries. - Expose DPLL clock quality level to the user-space. - Support master-slave PHY config via device tree.

2024-11-21wifi: ath11k: mark ath11k_wow_convert_8023_to_80211() as noinlineJeff Johnson
When compiling the ath11k driver using clang with KASAN enabled, the following warning is observed: drivers/net/wireless/ath/ath11k/wow.c:672:5: warning: stack frame size (1336) exceeds limit (1024) in 'ath11k_wow_op_suspend' [-Wframe-larger-than] This is similar to the issue found in ath12k/qmi.c that was discussed in [1] and fixed with [2]. The issue is that clang inlining can explode stack usage. ath11k_wow_op_suspend() itself is a pretty lightweight function, but it dispatches to several other functions which do the real work. One path in particular is: ath11k_wow_op_suspend() ath11k_wow_set_wakeups() ath11k_vif_wow_set_wakeups() ath11k_wow_convert_8023_to_80211() Of these, ath11k_wow_convert_8023_to_80211() has non-trivial stack usage, so mark it as 'noinline_for_stack' to prevent it from being inlined in ath11k_wow_op_suspend(), thereby eliminating the excessive stack usage.

Mark those functions as 'noinline_for_stack' to prevent them from being inlined in ath12k_qmi_driver_event_work(), thereby eliminating the excessive stack usage.

2024-11-21wifi: ath12k: Fix inappropriate use of print_array_to_buf_index()Roopni Devanathan
Currently in ath12k_htt_print_tx_pdev_mumimo_grp_stats_tlv() the htt_stats_buf->ul_mumimo_grp_best_usrs array is printed using print_array_to_buf_index() with a stats_index of 1. This is meant to convey the semantic that first entry in ul_mumimo_grp_best_usrs is associated with user 1. However, unlike some of the other "usr" arrays which have that semantic, ul_mumimo_grp_best_usrs does not have that semantic. Instead the first entry corresponds to user 0. Fix the issue by calling the API - print_array_to_buf(), instead of print_array_to_buf_index().
