This time of the type: skb->nh.iph = (struct iphdr *)skb->data; That is completely equivalent to: skb->nh.raw = skb->data; Wonder why people love casts... :-) Signed-off-by:

It returns skb->data, so we can just use skb_reset_network_header after it. Signed-off-by:

But only in the cases where its a newly allocated skb, i.e. one where skb->tail is equal to skb->data, or just after skb_reserve, where this requirement is maintained. Signed-off-by:

skb_push updates and returns skb->data, so we can just call skb_reset_network_header after the call to skb_push. Signed-off-by:

For the common, open coded 'skb->nh.raw = skb->data' operation, so that we can later turn skb->nh.raw into a offset, reducing the size of struct sk_buff in 64bit land while possibly keeping it as a pointer on 32bit. This one touches just the most simple case, next will handle the slightly more "complex" cases. Signed-off-by:

For consistency with all the other skb->nh.raw accessors. Also do some really obvious simplifications in pppoe_recvmsg, well the kfree_skb one is not so obvious, but free() and kfree() have the same behaviour (hint :-) ). Signed-off-by:

For the places where we need a pointer to the mac header, it is still legal to touch skb->mac.raw directly if just adding to, subtracting from or setting it to another layer header. This one also converts some more cases to skb_reset_mac_header() that my regex missed as it had no spaces before nor after '=', ugh. Signed-off-by:

That is equal to skb->head before skb_reserve, to help in the layer header changes. Signed-off-by:

For the cases where we want to set skb->mac.raw to an offset from skb->data. Simple cases first, the memmove ones and specially pktgen will be left for later. Signed-off-by:

skb->head is equal to skb->data after alloc_skb, so reset the mac header while this is true, i.e. before skb_reserve. Signed-off-by:

Now that network timestamps use ktime_t infrastructure, we can add a new SOL_SOCKET sockopt SO_TIMESTAMPNS. This command is similar to SO_TIMESTAMP, but permits transmission of a 'timespec struct' instead of a 'timeval struct' control message. (nanosecond resolution instead of microsecond) Control message is labelled SCM_TIMESTAMPNS instead of SCM_TIMESTAMP A socket cannot mix SO_TIMESTAMP and SO_TIMESTAMPNS : the two modes are mutually exclusive. sock_recv_timestamp() became too big to be fully inlined so I added a __sock_recv_timestamp() helper function.

Now network timestamps use ktime_t infrastructure, we can add a new ioctl() SIOCGSTAMPNS command to get timestamps in 'struct timespec'. User programs can thus access to nanosecond resolution. Signed-off-by:
