[NET]: IPV6 checksum offloading in network devices

2007-07-11T05:15:52+00:00

The existing model for checksum offload does not correctly handle
devices that can offload IPV4 and IPV6 only. The NETIF_F_HW_CSUM flag
implies device can do any arbitrary protocol.

This patch:
 * adds NETIF_F_IPV6_CSUM for those devices
 * fixes bnx2 and tg3 devices that need it
 * add NETIF_F_IPV6_CSUM to ipv6 output (incl GSO)
 * fixes assumptions about NETIF_F_ALL_CSUM in nat
 * adjusts bridge union of checksumming computation

[TCP]: Honour sk_bound_dev_if in tcp_v4_send_ack

2007-06-07T20:38:51+00:00

A time_wait socket inherits sk_bound_dev_if from the original socket,
but it is not used when sending ACK packets using ip_send_reply.

Fix by passing the oif to ip_send_reply in struct ip_reply_arg and
use it for output routing.

[IPV4] SNMP: Support OutMcastPkts and OutBcastPkts

2007-04-30T07:58:32+00:00

A transmitted IP multicast datagram should be counted as OutMcastPkts.
By the same token, a transmitted IP broadcast datagram should be
counted as OutBcastPkts.

[INET]: Add IP(V6)_PMTUDISC_RPOBE

2007-04-26T05:29:10+00:00

Add IP(V6)_PMTUDISC_PROBE value for IP(V6)_MTU_DISCOVER.  This option forces
us not to fragment, but does not make use of the kernel path MTU discovery.
That is, it allows for user-mode MTU probing (or, packetization-layer path
MTU discovery).  This is particularly useful for diagnostic utilities, like
traceroute/tracepath.

[SK_BUFF]: Introduce skb_copy_from_linear_data{_offset}

2007-04-26T05:28:23+00:00

To clearly state the intent of copying from linear sk_buffs, _offset being a
overly long variant but interesting for the sake of saving some bytes.

[SK_BUFF]: unions of just one member don't get anything done, kill them

2007-04-26T05:26:20+00:00

Renaming skb->h to skb->transport_header, skb->nh to skb->network_header and
skb->mac to skb->mac_header, to match the names of the associated helpers
(skb[_[re]set]_{transport,network,mac}_header).

[SK_BUFF]: Introduce skb_network_header_len

2007-04-26T05:26:19+00:00

For the common sequence "skb->h.raw - skb->nh.raw", similar to skb->mac_len,
that is precalculated tho, don't think we need to bloat skb with one more
member, so just use this new helper, reducing the number of non-skbuff.h
references to the layer headers even more.
