Detailed Description

The IPC backend uses a shared-memory message passing model via ipc_service, and therefore transfers fixed-size proxy frames (struct zbus_proxy_msg) between domains. This means on-wire transfer size is equal to sizeof(struct zbus_proxy_msg) even when message_size or channel_name_len are smaller. Because this frame size is determined at compile time from CONFIG_ZBUS_PROXY_AGENT_MAX_MESSAGE_SIZE and CONFIG_ZBUS_PROXY_AGENT_MAX_CHANNEL_NAME_SIZE, all communicating domains must use identical values for these options. The IPC backend validates incoming data against sizeof(struct zbus_proxy_msg), so mismatched configuration across domains will cause received messages to be rejected.
