[ATM]: Check IP header validity in mpc_send_packet

[ Upstream commit: 1c9b7aa1eb40ab708ef3242f74b9a61487623168 ]

Al went through the ip_fast_csum callers and found this piece of code
that did not validate the IP header.  While root crashing the machine
by sending bogus packets through raw or AF_PACKET sockets isn't that
serious, it is still nice to react gracefully.

This patch ensures that the skb has enough data for an IP header and
that the header length field is valid.

[SK_BUFF]: Introduce skb_copy_to_linear_data{_offset}

2007-04-26T05:28:29+00:00

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

[SK_BUFF]: Convert skb->end to sk_buff_data_t

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

Now to convert the last one, skb->data, that will allow many simplifications
and removal of some of the offset helpers.

[SK_BUFF]: Convert skb->tail to sk_buff_data_t

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

So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes
on 64bit architectures, allowing us to combine the 4 bytes hole left by the
layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4
64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN...
:-)

Many calculations that previously required that skb->{transport,network,
mac}_header be first converted to a pointer now can be done directly, being
meaningful as offsets or pointers.
