Repository : ssh://git@open-mesh.org/batman-adv On branch : master >--------------------------------------------------------------- commit 96c8c5b72ea0337692277598649d0a957248295c Author: Sven Eckelmann <sven(a)narfation.org> Date: Wed Nov 7 23:31:54 2018 +0100 batman-adv: Expand merged fragment buffer for full packet The complete size ("total_size") of the fragmented packet is stored in the fragment header and in the size of the fragment chain. When the fragments are ready for merge, the skbuff's tail of the first fragment is expanded to have enough room after the data pointer for at least total_size. This means that it gets expanded by total_size - first_skb->len. But this is ignoring the fact that after expanding the buffer, the fragment header is pulled by from this buffer. Assuming that the tailroom of the buffer was already 0, the buffer after the data pointer of the skbuff is now only total_size - len(fragment_header) large. When the merge function is then processing the remaining fragments, the code to copy the data over to the merged skbuff will cause an skb_over_panic when it tries to actually put enough data to fill the total_size bytes of the packet. The size of the skb_pull must therefore also be taken into account when the buffer's tailroom is expanded.
