[**\[Experimental Bot, please feedback here\]**](https://github.com/search?q=repo%3Aapache%2Fnuttx+13552&type=issues) No, this PR summary does not adequately meet the NuttX requirements. Here's why and how to fix it: **Missing Information in Summary:** * **Why is this change necessary?** It's stated *what* the change is (adding CAN support), but not *why*. Is this a frequently requested feature? Does it enable new functionality? Does it fix a bug or improve performance? * **How does it work?** A slightly more detailed explanation is needed. Mentioning SocketCAN is good, but how does the simulator interface with it? Are there new driver files? Configuration options? **Missing Information in Impact:** * Many "Impact" sections are completely blank. Even if the answer is "NO," explicitly state it. For example: * `Impact on user (will user need to adapt to change)? YES (Users will need to configure the simulator to use CAN and may need to install SocketCAN on the host.)` * `Impact on build (will build process change)? YES (New configuration options are available for enabling CAN support in the simulator build.)` * `Impact on hardware (will arch(s) / board(s) / driver(s) change)? YES (This affects the sim architecture and adds a new driver.)` * `Impact on documentation (is update required / provided)? YES (Documentation should be updated to explain how to configure and use the new CAN functionality.)` * **Security:** Even if there are no *obvious* security implications, consider potential issues. For example, could a malicious host application inject unexpected CAN messages into the simulated environment? If the answer is truly "NO", explicitly state why you believe there's no security impact. * **Compatibility:** Does this affect any existing simulator functionality? Are there backward compatibility concerns? **Missing Information in Testing:** * **Build Host(s):** Provide details about the host system used for testing. e.g., "Linux Ubuntu 20.04, x86_64, GCC 9.4.0" * **Target(s):** Be more specific. "sim:can" is a good start, but mention the simulator target if applicable (e.g., qemu-x86_64). * **Testing logs *before* change:** This section is empty. While not always strictly necessary for new features, it's helpful to show the absence of CAN functionality before the change. Even a simple "nsh> candump can0" resulting in an error would suffice. **Revised Example for the PR Summary:** ``` ## Summary This PR adds CAN bus support to the NuttX simulator, leveraging the host system's SocketCAN interface. This feature is essential for developing and testing CAN-based applications within the NuttX environment without requiring physical hardware. The implementation introduces a new CAN driver for the simulator that interacts with SocketCAN virtual interfaces. New configuration options are provided in the simulator build system to enable CAN support. Related Issue: [NuttX Issue #XXXX](If applicable) ## Impact * Is new feature added? YES (CAN bus support for the simulator) * Impact on user (will user need to adapt to change)? YES (Users will need to configure the simulator to use CAN, install SocketCAN on the host, and create a virtual CAN interface.) * Impact on build (will build process change)? YES (New configuration options (`CONFIG_SIM_CAN`, etc.) are added to enable CAN support in the simulator build. The `sim/can` configuration is also added.) * Impact on hardware (will arch(s) / board(s) / driver(s) change)? YES (This affects the `sim` architecture and adds a new CAN driver.) * Impact on documentation (is update required / provided)? YES (Documentation will be updated to explain how to configure and use the new CAN functionality, including host setup and NuttX configuration.) * Impact on security (any sort of implications)? NO (While a malicious host application could theoretically inject arbitrary CAN messages, this is inherent to using SocketCAN and not specific to this implementation. The simulator itself does not introduce any new security vulnerabilities.) * Impact on compatibility (backward/forward/interoperability)? NO (This change does not affect existing simulator functionality.) * Anything else to consider? None. ## Testing I confirm that changes are verified on local setup and works as intended: * Build Host(s): Linux Ubuntu 22.04, x86_64, GCC 11.2.0 * Target(s): sim:can (qemu-x86_64) Testing logs before change: ``` nsh> candump can0 candump: can0: Device not found ``` Testing logs after change: [... your existing logs here ...] ``` By providing more complete and specific information, you make it significantly easier for reviewers to understand and approve your PR. -- This is an automated message from the Apache Git Service.
