We only have a single flag free, and before using that for another mactime flag, instead refactor the mactime flags to use a 2-bit field. Signed-off-by:

UHB AP send supported power type(LPI, SP, VLP) in beacon and probe response IE and STA should connect to these AP only if their regulatory support the AP power type. Beacon/Probe response are reported to userspace with reason "STA regulatory not supporting to connect to AP based on transmitted power type" and it should not connect to AP. Signed-off-by:

Due to different relaxation policies it may be needed to re-check channels after a BSS station interface is disconnected or performed a channel switch. Signed-off-by:

Andrei Otcheretianski authored
FCC-594280 D01 Section B.3 allows peer-to-peer and ad hoc devices to operate on DFS channels while they operate under the control of a concurrent DFS master. For example, it is possible to have a P2P GO on a DFS channel as long as BSS connection is active on the same channel. Allow such operation by adding additional regulatory flags to indicate DFS concurrent channels and capable devices. Add the required relaxations in DFS regulatory checks. Signed-off-by:

It is possible for the TX status report for the (Re)Association Request frame to be delayed long enough for the AP's (Re)Association Response frame to be received and processed before it. If that were to happen for a case where the AP rejects the association with indication to come back later, the association timeout and retry state should not be modified anymore with the TX status information that would be processed after this. Updating the association timeout in such a reverse order of events could result in shortening the timeouts for the association comeback mechanism and that could result in the association failing. Track whether we have already processed association rejection with comeback time and if so, skip the timeout and retry update on any following TX status report. Signed-off-by:

Because some platform Bluetooth will have many background scan when idle. And the frequently Bluetooth scan will break Wi-Fi traffic many times at a short duration, it will make Wi-Fi throughput become lower. This patch will shorter Bluetooth slot and adjust priority settings, make Wi-Fi can have a more completed duration to do traffic. Signed-off-by:

Coexistence will set the RF parameter according to Wi-Fi link mode, Wi-Fi/Bluetooth signal level, traffic direction, antenna type, and is there Bluetooth connection exist or not. Bluetooth will notify the current LNA level by scoreboard. If the setting not as expected, coexistence will try to assign the correct level. Signed-off-by:

Including Wi-Fi RF mode to judge is Wi-Fi RF still on or off, if Wi-Fi is RF off should set scoreboard to let Bluetooth know Wi-Fi has gone. Every time the Wi-Fi radio state changed firmware should force execute refresh the TDMA coexistence mechanism to prevent incorrect mechanism runs at mismatch state. The coexistence antenna/TDMA settings should consider what the Wi-Fi mode it is now, this can help to solve some LPS transient state issue like A2DP slightly glitch. Signed-off-by:

BTG is a RF system type, it means Wi-Fi 2.4GHz and Bluetooth share RF gain and antenna. The RF gain must control by Wi-Fi or Bluetooth in single side. For example, if Bluetooth RX a very strong signal, then Bluetooth will adjust to a lower gain. And Wi-Fi will also use the same gain to do RX, then maybe the gain will not enough. This BTG control mechanism can do some refine to this situation. Signed-off-by:

Pre-AGC(Auto gain control) is a hardware mechanism, it will auto adjust the RX gain for every packet, it can help to keep Wi-Fi signal on a well RX quality. The coexistence will give advice to control the API and monitor the settings by firmware report. Also add function to check register, these registers were monitoring by Wi-Fi firmware and report to coexistence driver periodically. This can help to track whether these settings were taking effect or not. Signed-off-by:

After enabling DMAC and CMAC, configure detail registers one by one. DMAC includes DLE (data link engine), packet preload engine, HFC (HCI flow control) for DMA channels, security egine and etc. CMAC includes scheduler, address CAM, RX filter, CCA control and etc. The SER IMR is to configure to help SER. When hardware TX/RX get abnormal, it raises an interrupt to firmware to determine if send C2H events to notify driver to reset PCI bus or call ieee80211_restart_hw(). Signed-off-by:

The sys_init is to enable hardware function block of DMAC (data-path MAC), CMAC (control-path MAC) and others called 'chip_func'. To understand the functionality of this function, we keep some functions as empty. The other is typ_fltr_opt that is to configure filter option to decide whether RX packets engine can forward packets to host or WiFi CPU. Signed-off-by:

Alexei Starovoitov says: ==================== pull-request: bpf-next 2023-12-18 This PR is larger than usual and contains changes in various parts of the kernel. The main changes are: 1) Fix kCFI bugs in BPF, from Peter Zijlstra. End result: all forms of indirect calls from BPF into kernel and from kernel into BPF work with CFI enabled. This allows BPF to work with CONFIG_FINEIBT=y. 2) Introduce BPF token object, from Andrii Nakryiko. It adds an ability to delegate a subset of BPF features from privileged daemon (e.g., systemd) through special mount options for userns-bound BPF FS to a trusted unprivileged application. The design accommodates suggestions from Christian Brauner and Paul Moore. Example: $ sudo mkdir -p /sys/fs/bpf/token $ sudo mount -t bpf bpffs /sys/fs/bpf/token \ -o delegate_cmds=prog_load:MAP_CREATE \ -o delegate_progs=kprobe \ -o delegate_attachs=xdp 3) Various verifier improvements and fixes, from Andrii Nakryiko, Andrei Matei. - Complete precision tracking support for register spills - Fix verification of possibly-zero-sized stack accesses - Fix access to uninit stack slots - Track aligned STACK_ZERO cases as imprecise spilled registers. It improves the verifier "instructions processed" metric from single digit to 50-60% for some programs. - Fix verifier retval logic 4) Support for VLAN tag in XDP hints, from Larysa Zaremba. 5) Allocate BPF trampoline via bpf_prog_pack mechanism, from Song Liu. End result: better memory utilization and lower I$ miss for calls to BPF via BPF trampoline. 6) Fix race between BPF prog accessing inner map and parallel delete, from Hou Tao. 7) Add bpf_xdp_get_xfrm_state() kfunc, from Daniel Xu. It allows BPF interact with IPSEC infra. The intent is to support software RSS (via XDP) for the upcoming ipsec pcpu work. Experiments on AWS demonstrate single tunnel pcpu ipsec reaching line rate on 100G ENA nics. 8) Expand bpf_cgrp_storage to support cgroup1 non-attach, from Yafang Shao. 9) BPF file verification via fsverity, from Song Liu. It allows BPF progs get fsverity digest. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (164 commits) bpf: Ensure precise is reset to false in __mark_reg_const_zero() selftests/bpf: Add more uprobe multi fail tests bpf: Fail uprobe multi link with negative offset selftests/bpf: Test the release of map btf s390/bpf: Fix indirect trampoline generation selftests/bpf: Temporarily disable dummy_struct_ops test on s390 x86/cfi,bpf: Fix bpf_exception_cb() signature bpf: Fix dtor CFI cfi: Add CFI_NOSEAL() x86/cfi,bpf: Fix bpf_struct_ops CFI x86/cfi,bpf: Fix bpf_callback_t CFI x86/cfi,bpf: Fix BPF JIT call cfi: Flip headers selftests/bpf: Add test for abnormal cnt during multi-kprobe attachment selftests/bpf: Don't use libbpf_get_error() in kprobe_multi_test selftests/bpf: Add test for abnormal cnt during multi-uprobe attachment bpf: Limit the number of kprobes when attaching program to multiple kprobes bpf: Limit the number of uprobes when attaching program to multiple uprobes bpf: xdp: Register generic_kfunc_set with XDP programs selftests/bpf: utilize string values for delegate_xxx mount options ... ==================== Link: https://lore.kernel.org/r/20231219000520.34178-1-alexei.starovoitov@gmail.comSigned-off-by:Jakub Kicinski <kuba@kernel.org>
