This check is crucial for ensuring that the structure is correctly mapped onto the Netlink message, providing a layer of security. To streamline this process, Jakub Kicinski suggested creating a helper function, `nlmsg_payload`, which verifies if the structure fits within the message. If it does, the function returns the data; otherwise, it returns NULL. This approach simplifies the code and reduces redundancy. This patchset introduces the `nlmsg_payload` helper and updates several parts of the code to use it. Further updates will follow in subsequent patchsets. v1: https://lore.kernel.org/20250411-nlmsg-v1-0-ddd4e065cb15@debian.org ==================== Link: https://patch.msgid.link/20250414-nlmsg-v2-0-3d90cb42c6af@debian.org Signed-off-by: Jakub Kicinski --- 2f8cc49d869cbfa6f72068774b3de420536c21ac
