Currently struct wmi_tdls_peer_capabilities defines: struct wmi_channel peer_chan_list[1]; Per the guidance in [1] this should be a flexible array, and at one point Gustavo was trying to fix this [2], but had questions about the correct behavior when the associated peer_chan_len is 0. I have been unable to determine if firmware requires that at least one record be present even if peer_chan_len is 0. But since that is the current behavior, follow the example from [3] and replace the one-element array with a union that contains both a flexible array and a single instance of the array element. This results in a struct that has the same footprint as the original, so no other driver changes are required. No functional changes, compile tested only.

2023-12-18wifi: ath10k: use flexible arrays for WMI start scan TLVsJeff Johnson
Currently ath10k defines the following struct: struct wmi_start_scan_tlvs { u8 tlvs[0]; } __packed; Per the guidance in [1] this should be a flexible array. However, a direct replace to u8 tlvs[] results in the compilation error: flexible array member in a struct with no named members This is because C99 6.7.2.1 (16) requires that a structure containing a flexible array member must have more than one named member. So rather than defining a separate struct wmi_start_scan_tlvs which contains the flexible tlvs[] array, just define the tlvs[] array where struct wmi_start_scan_tlvs is being used.

2023-12-07wifi: ath10k: add support to allow broadcast action frame RXJames Prestwood
Broadcast action frames are needed for the Device Provisioning Protocol (DPP) for Presence and PKEX Exchange requests. Currently just ath9k has this capability so this is being enabled for ath10k (for at least one hardware variant). Add a new capability flag in ath10k_hw_params to indicate support for receiving multicast action frames. This bit is then checked when configuring the RX filter and (if set) multicast action frame registration is enabled. Until more hardware can be tested only the "qca6174 hw3.2" variant is enabling this feature. Note: I went ahead and removed the 'changed_flags' mask operation since it had no effect, that parameter was not being used anywhere.

ATH10K_SCAN_STARTING state Scan failure can not be recovered from when running a loop of the following steps: 1. run scan: "iw wlan scan". 2. run command: echo soft > /sys/kernel/debug/ieee80211/phy0/ath10k/simulate_fw_crash immediately after step 1. result: scan failed and can not recover even when wlan recovery succeeds: command failed: Device or resource busy (-16) reason: When scan arrives, WMI_START_SCAN_CMDID is sent to the firmware and function ath10k_hw_scan() returns, then simulate_fw_crash arrives and the scan started event does not arrive, and then it starts to do recovery of wlan. __ath10k_scan_finish() which is called from ath10k_halt() is one step of recovery, it will not call ieee80211_scan_completed() by logic currently because the scan state is ATH10K_SCAN_STARTING. Thus it leads the scan not being completed in mac80211, and leads all consecutive scans failing with -EBUSY in nl80211_trigger_scan even after wlan recovery success. Indicate scan complete with aborted flag to mac80211 for ATH10K_SCAN_STARTING to allow recovery from scan failed with "Device or resource busy (-16)" after wlan recovery.

2023-10-02wifi: ath10k: Don't touch the CE interrupt registers after power upDouglas Anderson
As talked about in commit d66d24ac300c ("ath10k: Keep track of which interrupts fired, don't poll them"), if we access the copy engine register at a bad time then ath10k can go boom. However, it's not necessarily easy to know when it's safe to access them. The ChromeOS test labs saw a crash that looked like this at shutdown/reboot time (on a chromeos-5.15 kernel, but likely the problem could also reproduce upstream): Internal error: synchronous external abort: 96000010 [#1] PREEMPT SMP ... CPU: 4 PID: 6168 Comm: reboot Not tainted 5.15.111-lockdep-19350-g1d624fe6758f #1 010b9b233ab055c27c6dc88efb0be2f4e9e86f51 Hardware name: Google Kingoftown (DT) ... pc : ath10k_snoc_read32+0x50/0x74 [ath10k_snoc] lr : ath10k_snoc_read32+0x24/0x74 [ath10k_snoc] ...

Let's fix this by changing how we "disable" the interrupts. Instead of tweaking the copy engine registers we'll just use disable_irq() and enable_irq(). Then we'll configure the interrupts once at power up time.

2023-08-25Fix nomenclature for USB and PCI wireless devicesAlan Stern
A mouse that uses a USB connection is called a "USB mouse" device (or "USB mouse" for short), not a "mouse USB" device. By analogy, a WiFi adapter that connects to the host computer via USB is a "USB wireless" device, not a "wireless USB" device. (The latter term more properly refers to a defunct Wireless USB specification, which described a technology for sending USB protocol messages over an ultra wideband radio link.) Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a "PCIe wireless" device, not a "wireless PCIe" device. Rephrase the text in the kernel source where the word ordering is wrong.

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree.

The latter will definitely require fixes but I think that we got it to a reasonable point. Core: - Rework the sendpage & splice implementations Instead of feeding data into sockets page by page extend sendmsg handlers to support taking a reference on the data, controlled by a new flag called MSG_SPLICE_PAGES Rework the handling of unexpected-end-of-file to invoke an additional callback instead of trying to predict what the right combination of MORE/NOTLAST flags is Remove the MSG_SENDPAGE_NOTLAST flag completely - Implement SCM_PIDFD, a new type of CMSG type analogous to SCM_CREDENTIALS, but it contains pidfd instead of plain pid - Enable socket busy polling with CONFIG_RT - Improve reliability and efficiency of reporting for ref_tracker - Auto-generate a user space C library for various Netlink families Protocols: - Allow TCP to shrink the advertised window when necessary, prevent sk_rcvbuf auto-tuning from growing the window all the way up to tcp_rmem[2] - Use per-VMA locking for "page-flipping" TCP receive zerocopy - Prepare TCP for device-to-device data transfers, by making sure that payloads are always attached to skbs as page frags - Make the backoff time for the first N TCP SYN retransmissions linear. Exponential backoff is unnecessarily conservative - Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO) - Avoid waking up applications using TLS sockets until we have a full record - Allow using kernel memory for protocol ioctl callbacks, paving the way to issuing ioctls over io_uring - Add nolocalbypass option to VxLAN, forcing packets to be fully encapsulated even if they are destined for a local IP address - Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure in-kernel ECMP implementation (e.g. Open vSwitch) select the same link for all packets. Support L4 symmetric hashing in Open vSwitch - PPPoE: make number of hash bits configurable - Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client (ipconfig) - Add layer 2 miss indication and filtering, allowing higher layers (e.g. ACL filters) to make forwarding decisions based on whether packet matched forwarding state in lower devices (bridge) - Support matching on Connectivity Fault Management (CFM) packets - Hide the "link becomes ready" IPv6 messages by demoting their printk level to debug - HSR: don't enable promiscuous mode if device offloads the proto - Support active scanning in IEEE 802.15.4 - Continue work on Multi-Link Operation for WiFi 7 BPF: - Add precision propagation for subprogs and callbacks. This allows maintaining verification efficiency when subprograms are used, or in fact passing the verifier at all for complex programs, especially those using open-coded iterators - Improve BPF's {g,s}setsockopt() length handling. Previously BPF assumed the length is always equal to the amount of written data.

2023-06-09wifi: ath10k: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Both ath10k platform drivers return zero unconditionally in their remove callback, so they can be trivially converted to use .remove_new(). Also fix on of the more offending whitespace issues in the definition of ath10k_snoc_driver.

2023-06-09wifi: ath10k: Drop checks that are always falseUwe Kleine-König
platform_get_drvdata() cannot return NULL as the probe function calls platform_set_drvdata() with a non-NULL argument or returns with a failure. In the first case, platform_get_drvdata() returns this non-NULL value and in the second the remove callback isn't called at all. ath10k_ahb_priv() cannot return NULL and ar_ahb is unused after the check anyhow.

2023-06-01wifi: ath10k: Trigger STA disconnect after reconfig complete on hardware restartYoughandhar Chintala
Currently, on WCN3990, the station disconnect after hardware recovery is not working as expected. This is because of setting the IEEE80211_SDATA_DISCONNECT_HW_RESTART flag very early in the hardware recovery process even before the driver invokes ieee80211_hw_restart(). On the contrary, mac80211 expects this flag to be set after ieee80211_hw_restart() is invoked for it to trigger station disconnect. Set the IEEE80211_SDATA_DISCONNECT_HW_RESTART flag in ath10k_reconfig_complete() instead to fix this. The other targets are not affected by this change, since the hardware params flag is not set.

2023-05-18wifi: ath10/11/12k: Use alloc_ordered_workqueue() to create ordered workqueuesTejun Heo
BACKGROUND ========== When multiple work items are queued to a workqueue, their execution order doesn't match the queueing order. They may get executed in any order and simultaneously. When fully serialized execution - one by one in the queueing order - is needed, an ordered workqueue should be used which can be created with alloc_ordered_workqueue(). However, alloc_ordered_workqueue() was a later addition. Before it, an ordered workqueue could be obtained by creating an UNBOUND workqueue with @max_active==1. This originally was an implementation side-effect which was broken by 4c16bd327c74 ("workqueue: restore WQ_UNBOUND/max_active==1 to be ordered"). Because there were users that depended on the ordered execution, 5c0338c68706 ("workqueue: restore WQ_UNBOUND/max_active==1 to be ordered") made workqueue allocation path to implicitly promote UNBOUND workqueues w/ @max_active==1 to ordered workqueues. While this has worked okay, overloading the UNBOUND allocation interface this way creates other issues. It's difficult to tell whether a given workqueue actually needs to be ordered and users that legitimately want a min concurrency level wq unexpectedly gets an ordered one instead. With planned UNBOUND workqueue updates to improve execution locality and more prevalence of chiplet designs which can benefit from such improvements, this isn't a state we wanna be in forever. This patch series audits all callsites that create an UNBOUND workqueue w/ @max_active==1 and converts them to alloc_ordered_workqueue() as necessary. WHAT TO LOOK FOR ================ The conversions are from alloc_workqueue(WQ_UNBOUND | flags, 1, args..) to alloc_ordered_workqueue(flags, args...) which don't cause any functional changes. If you know that fully ordered execution is not ncessary, please let me know. I'll drop the conversion and instead add a comment noting the fact to reduce confusion while conversion is in progress. If you aren't fully sure, it's completely fine to let the conversion through. The behavior will stay exactly the same and we can always reconsider later. As there are follow-up workqueue core changes, I'd really appreciate if the patch can be routed through the workqueue tree w/ your acks. Thanks.
