Dear all, I have a question on the tun/tap module and the network-stack.
when we write a packet to: "tun_chr_aio_write", it will be transported to: "tun_get_user", it will be sent to the network-stack via: "netif_rx_ni" to "netif_rx", where it will be handled by "netpoll_rx". if "netpoll_rx" returns true "netif_rx" will return with "NET_RX_DROP" (http://lxr.linux.no/linux+v2.6.27.4/net/core/dev.c#L1905) but in this case skb won't be freed anywhere in the source. do I miss something, or could a potential heapoverflow occur in the kernel? best regards, Matthias -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
