2007-04-25[SK_BUFF]: Introduce skb_reset_transport_header(skb)Arnaldo Carvalho de Melo
For the common, open coded 'skb->h.raw = skb->data' operation, so that we can later turn skb->h.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 cases: skb->h.raw = skb->data; skb->h.raw = {skb_push|[__]skb_pull}() The next ones will handle the slightly more "complex" cases.

2007-04-25[SK_BUFF]: Introduce ipv6_hdr(), remove skb->nh.ipv6hArnaldo Carvalho de Melo
Now the skb->nh union has just one member, .raw, i.e. it is just like the skb->mac union, strange, no? I'm just leaving it like that till the transport layer is done with, when we'll rename skb->mac.raw to skb->mac_header (or ->mac_header_offset?), ditto for ->{h,nh}.

2007-04-25[IP]: Introduce ip_hdrlen()Arnaldo Carvalho de Melo
For the common sequence "skb->nh.iph->ihl * 4", removing a good number of open coded skb->nh.iph uses, now to go after the rest... Just out of curiosity, here are the idioms found to get the same result: skb->nh.iph->ihl << 2 skb->nh.iph->ihl<<2 skb->nh.iph->ihl * 4 skb->nh.iph->ihl*4 (skb->nh.iph)->ihl * sizeof(u32) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S.

2007-04-25[SK_BUFF]: Introduce skb_network_header()Arnaldo Carvalho de Melo

2007-04-25[SK_BUFF] ipv6: More skb_reset_network_header conversions related to skb_pullArnaldo Carvalho de Melo
Now related to this form: skb->nh.ipv6h = (struct ipv6hdr *)skb_put(skb, length); That, as the others, is done when skb->tail is still equal to skb->data, making the conversion to skb_reset_network_header possible. Also one more case equivalent to skb->nh.raw = skb->data, of this form: iph = (struct ipv6hdr *)skb->data; <SNIP> skb->nh.ipv6h = iph; Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S.

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.

2007-04-25[NET]: Adding SO_TIMESTAMPNS / SCM_TIMESTAMPNS supportEric Dumazet
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.
