[PATCH v9 0/3] MR6315: plugplay: Rework how PnP notifications are sent over RPC to support DBT_DEVTYP_HANDLE events.
PnP device notifications/events are currently sent and received from the `plugplay` service as the raw-bytes for the `DBT_DEVTYP_DEVICEINTERFACE` struct that needs to be sent from the PnP code in `ntoskrnl.exe`. While simple, it does not support sending `DBT_DEVTYP_HANDLE` events, as they also include a `HANDLE` to the device the event comes from, which cannot simply be sent as raw bytes. This MR reworks how notifications are sent and received from the `plugplay` service, by: 1. Introducing new structs `DEVICE_BROADCAST_HANDLE` and `DEVICE_BROADCAST_DEVICEINTERFACE` in `plugplay.idl`. The structs are similar to their counterparts in `dbt.h` without the `devicetype` and `size` fields added for the header. 2. Re-write `plugplay_{send,get}_event` to use the newly added union `DEVICE_BROADCAST`, which uses the `devicetype` value as the discriminant. A deep copy of this union is then appended to the event queue of every registered listener. 3. Re-write `I_ScRegisterDeviceNotification` and `device_notify_proc` in `sechost/service.c` to use the newly added types instead. Additionally, add support for registering for `DBT_DEVTYPE_HANDLE` notifications, for which the `OBJECT_NAME_INFORMATION` value for the device `HANDLE` is used to filter notifications in order to correctly dispatch them to their registered callbacks. 4. Re-write the callbacks in `user32/input.c` to accept the `DEVICE_BROADCAST` union instead, and construct the appropriate `DEV_BROADCAST_*` struct from it, which gets sent to `SendMessageTimeoutW` as usual. Support for `DBT_DEVTYP_HANDLE` is needed for the Bluetooth driver stack I have been working on recently, which uses `DBT_DEVTYP_HANDLE` events to notify userspace about newly found Bluetooth devices during discovery and incoming authentication requests, as documented by MS [here](https://learn.microsoft.com/en-us/windows/win32/bluetooth/bluetooth-and-wm-d...). -- v9: plugplay: Rewrite RPC interface to send and receive events using the newly introduced DEVICE_BROADCAST types. include/wine: Add header dbt.h. https://gitlab.winehq.org/wine/wine/-/merge_requests/6315
From: Vibhav Pant <vibhavp(a)gmail.com> Instead of sending and receiving events from plugplay as single array of bytes, introduce a new union, DEVICE_BROADCAST. The union currently supports the types DEVICE_BROADCAST_HANDLE and DEVICE_BROADCAST_DEVICEINTERFACE for the DBT_DEVTYP_HANDLE and DBT_DEVTYP_DEVICEINTERFACE event codes respectively, and define individual fields corresponding to their equivalent structs in dbt.h. While this introduces some additional complexity while converting from a DEVICE_BROADCAST to a DEV_BROADCAST_* type, it also allows support for DBT_DEVTYP_HANDLE events to be sent, which was not supported with the previous raw-bytes method, as the DEV_BROADCAST_HANDLE struct was identified with a HANDLE to the originating device file. --- include/wine/plugplay.idl | 37 +++++++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) diff --git a/include/wine/plugplay.idl b/include/wine/plugplay.idl index a3e7b04bf30..d5aaebe388e 100644 --- a/include/wine/plugplay.idl +++ b/include/wine/plugplay.idl @@ -1,5 +1,6 @@ /* * Copyright (C) 2020 Zebediah Figura for CodeWeavers + * Copyright (C) 2024 Vibhav Pant * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public @@ -18,6 +19,42 @@ import "wtypes.idl"; +typedef enum _broadcast_device_type +{ + /* DBT_DEVTYP_DEVICEINTERFACE */ + BROADCAST_DEVICE_TYPE_DEVICEINTERFACE = 5, + /* DBT_DEVTYP_HANDLE */ + BROADCAST_DEVICE_TYPE_HANDLE = 6 +} broadcast_device_type; + +typedef struct _device_broadcast_header +{ + DWORD reserved; +} device_broadcast_header; + +typedef struct _device_broadcast_deviceinterface +{ + device_broadcast_header header; + GUID class_guid; + [string] LPWSTR name; +} device_broadcast_deviceinterface; + +typedef struct _device_broadcast_handle +{ + device_broadcast_header header; + LPWSTR handle_file_path; + GUID event_guid; + [string] LPWSTR name; + DWORD data_size; + [unique, size_is(data_size)] BYTE *data; +} device_broadcast_handle; + +typedef union _device_broadcast switch (broadcast_device_type devicetype) event +{ + case BROADCAST_DEVICE_TYPE_DEVICEINTERFACE: device_broadcast_deviceinterface device_interface; + case BROADCAST_DEVICE_TYPE_HANDLE: device_broadcast_handle handle; +} device_broadcast; + [ uuid(57c680ac-7bce-4f39-97fd-ffea566754d5), endpoint("ncacn_np:[\\pipe\\wine_plugplay]"), -- GitLab https://gitlab.winehq.org/wine/wine/-/merge_requests/6315

Hi, It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated. The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful.
