Youssef Samir 0066d4bac5 net: qrtr: Update packets cloning when broadcasting ... [ Upstream commit f011b313e8 ] When broadcasting data to multiple nodes via MHI, using skb_clone() causes all nodes to receive the same header data. This can result in packets being discarded by endpoints, leading to lost data. This issue occurs when a socket is closed, and a QRTR_TYPE_DEL_CLIENT packet is broadcasted. All nodes receive the same destination node ID, causing the node connected to the client to discard the packet and remain unaware of the client's deletion. Replace skb_clone() with pskb_copy(), to create a separate copy of the header for each sk_buff.
