2023-10-27ipvlan: properly track tx_errorsEric Dumazet2-4/+5
Both ipvlan_process_v4_outbound() and ipvlan_process_v6_outbound() increment dev->stats.tx_errors in case of errors. Unfortunately there are two issues : 1) ipvlan_get_stats64() does not propagate dev->stats.tx_errors to user. 2) Increments are not atomic. KCSAN would complain eventually. Use DEV_STATS_INC() to not miss an update, and change ipvlan_get_stats64() to copy the value back to user. Fixes: 2ad7bf363841 ("ipvlan: Initial check-in of the IPVLAN driver.")

2023-10-27netdevsim: Block until all devices are releasedIdo Schimmel1-0/+12
Like other buses, devices on the netdevsim bus have a release callback that is invoked when the reference count of the device drops to zero. However, unlike other buses such as PCI, the release callback is not necessarily built into the kernel, as netdevsim can be built as a module. The above is problematic as nothing prevents the module from being unloaded before the release callback has been invoked, which can happen asynchronously. One such example can be found in commit a380687200e0 ("devlink: take device reference for devlink object") where devlink calls put_device() from an RCU callback. The issue is not theoretical and the reproducer in [1] can reliably crash the kernel. The conclusion of this discussion was that the issue should be solved in netdevsim, which is what this patch is trying to do. Add a reference count that is increased when a device is added to the bus and decreased when a device is released. Signal a completion when the reference count drops to zero and wait for the completion when unloading the module so that the module will not be unloaded before all the devices were released. The reference count is initialized to one so that completion is only signaled when unloading the module. With this patch, the reproducer in [1] no longer crashes the kernel.

2023-10-27net: dsa: microchip: ksz9477: Add Wake on Magic Packet supportOleksij Rempel3-7/+97
Introduce Wake on Magic Packet (WoL) functionality to the ksz9477 driver. Major changes include: 1. Extending the `ksz9477_handle_wake_reason` function to identify Magic Packet wake events alongside existing wake reasons. 2. Updating the `ksz9477_get_wol` and `ksz9477_set_wol` functions to handle WAKE_MAGIC alongside the existing WAKE_PHY option, and to program the switch's MAC address register accordingly when Magic Packet wake-up is enabled. This change will prevent WAKE_MAGIC activation if the related port has a different MAC address compared to a MAC address already used by HSR or an already active WAKE_MAGIC on another port. 3. Adding a restriction in `ksz_port_set_mac_address` to prevent MAC address changes on ports with active Wake on Magic Packet, as the switch's MAC address register is utilized for this feature.

2023-10-25iavf: in iavf_down, disable queues when removing the driverMichal Schmidt1-1/+1
In iavf_down, we're skipping the scheduling of certain operations if the driver is being removed. However, the IAVF_FLAG_AQ_DISABLE_QUEUES request must not be skipped in this case, because iavf_close waits for the transition to the __IAVF_DOWN state, which happens in iavf_virtchnl_completion after the queues are released. Without this fix, "rmmod iavf" takes half a second per interface that's up and prints the "Device resources not yet released" warning.

2023-10-25sh: Remove stale microdev boardArnd Bergmann1-19/+0
This board was an early prototype platform for early SH4 CPUs and related to the already removed SH5 cayman platform. The microdev board itself has been kept in the tree for this long despite being in a bad shape even 20 years ago when it got merged, with no working PCI support and ugly workarounds for its I/O port implementation that try to emulate PC style peripheral access despite being quite different in reality. As far as I can tell, the ethernet, display, USB and PCI devices on it already broke at some point (afbb9d8d5266b, 46bc85872040a), so I think we can just removeit entirely.

2023-10-25wifi: ath12k: Introduce and use ath12k_sta_to_arsta()Jeff Johnson4-11/+16
Currently, the logic to return an ath12k_sta pointer, given a ieee80211_sta pointer, uses typecasting throughout the driver. In general, conversion functions are preferable to typecasting since using a conversion function allows the compiler to validate the types of both the input and output parameters. ath12k already defines a conversion function ath12k_vif_to_arvif() for a similar conversion. So introduce ath12k_sta_to_arsta() for this use case, and convert all of the existing typecasting to use this function.

2023-10-25wifi: ath11k: add firmware-2.bin supportAnilkumar Kolli7-17/+258
Firmware IE containers can dynamically provide various information what firmware supports. Also it can embed more than one image so updating firmware is easy, user just needs to update one file in /lib/firmware/. The firmware API 2 or higher will use the IE container format, the current API 1 will not use the new format but it still is supported for some time. Firmware API 2 files are named as firmware-2.bin (which contains both amss.bin and m3.bin images) and API 1 files are amss.bin and m3.bin. Currently ath11k PCI driver provides firmware binary (amss.bin) path to MHI driver, MHI driver reads firmware from filesystem and boots it. Add provision to read firmware files from ath11k driver and provide the amss.bin firmware data and size to MHI using a pointer. Currently enum ath11k_fw_features is empty, the patches adding features will add the flags. With AHB devices there's no amss.bin or m3.bin, so no changes in how AHB firmware files are used. But AHB devices can use future additions to the meta data, for example in enum ath11k_fw_features.

2023-10-25wifi: ath11k: qmi: refactor ath11k_qmi_m3_load()Kalle Valo1-7/+11
Simple refactoring to make it easier to add firmware-2.bin support in the following patch. Earlier ath11k_qmi_m3_load() supported changing m3.bin contents while ath11k is running. But that's not going to actually work, m3.bin is supposed to be the same during the lifetime of ath11k, for example we don't support changing the firmware capabilities on the fly. Due to this ath11k requests m3.bin firmware file first and only then checks m3_mem->vaddr, so we are basically requesting the firmware file even if it's not needed. Reverse the code so that m3_mem buffer is checked first, and only if it doesn't exist, then m3.bin is requested from user space. Checking for m3_mem->size is redundant when m3_mem->vaddr is NULL, we would not be able to use the buffer in that case. So remove the check for size. Simplify the exit handling and use 'goto out'.
