Fix get_curr_sync_buff to keep buffer for 2 seconds
as intended, not just for the current jiffie. By this way
we will sync more connection structures with single packet.

ip_vs_sync_cleanup() may be called from ip_vs_init() on error

The recent netns changes omitted to change
sock_create_kernel() to __sock_create() in ip_vs_sync.c
The effect of this is that the interface will be selected in the
root-namespace, from my point of view it's a major bug.

Connection hash table is now name space aware.
i.e. net ptr >> 8 is xor:ed to the hash,
and this is the first param to be compared.
The net struct is 0xa40 in size ( a little bit smaller for 32 bit arch:s)
and cache-line aligned, so a ptr >> 5 might be a more clever solution ?
All lookups where net is compared uses net_eq() which returns 1 when netns
is disabled, and the compiler seems to do something clever in that case.
ip_vs_conn_fill_param() have *net as first param now.
Three new inlines added to keep conn struct smaller
when names space is disabled.
- ip_vs_conn_net()
- ip_vs_conn_net_set()
- ip_vs_conn_net_eq()
*v3
moved net compare to the end in "fast path"

Services hash tables got netns ptr a hash arg,
While Real Servers (rs) has been moved to ipvs struct.
Two new inline functions added to get net ptr from skb.
Since ip_vs is called from different contexts there is two
places to dig for the net ptr skb->dev or skb->sk
this is handled in skb_net() and skb_sknet()
Global functions, ip_vs_service_get() ip_vs_lookup_real_service()
etc have got struct net *net as first param.
If possible get net ptr skb etc,
- if not &init_net is used at this early stage of patching.
ip_vs_ctl.c procfs not ready for netns yet.
*v3
Comments by Julian
- __ip_vs_service_find and __ip_vs_svc_fwm_find are fast path,
net_eq(svc->net, net) so the check is at the end now.
- net = skb_net(skb) in ip_vs_out moved after check for skb_dst.

Preparation for network name-space init, in this stage
some empty functions exists.
In most files there is a check if it is root ns i.e. init_net
if (!net_eq(net, &init_net))
return ...
this will be removed by the last patch, when enabling name-space.
*v3
ip_vs_conn.c merge error corrected.

Enable sending and removal of version 0 sending
Affected functions,
ip_vs_sync_buff_create()
ip_vs_sync_conn()
ip_vs_core.c removal of IPv4 check.
*v5
Just check cp->pe_data_len in ip_vs_sync_conn
Check if padding needed before adding a new sync_conn
to the buffer, i.e. avoid sending padding at the end.
*v4
moved sanity check and pe_name_len after sloop.
use cp->pe instead of cp->dest->svc->pe
real length in each sync_conn, not padded length
however total size of a sync_msg includes padding.
*v3
Sending ip_vs_sync_conn_options in network order.
Sending Templates for ONE_PACKET conn.
Renaming of ip_vs_sync_mesg to ip_vs_sync_mesg_v0

Functionality improvements
* flags changed from 16 to 32 bits
* fwmark added (32 bits)
* timeout in sec. added (32 bits)
* pe data added (Variable length)
* IPv6 capabilities (3x16 bytes for addr.)
* Version and type in every conn msg.
ip_vs_process_message() now handles Version 1 messages
and will call ip_vs_process_message_v0() for version 0 messages.
ip_vs_proc_conn() is common for both version, and handles the update of
connection hash.
ip_vs_conn_fill_param_sync() - Version 1 messages only

static inline wait_queue_head_t *sk_sleep(struct sock *sk)

return sk->sk_sleep;
}
Change all read occurrences of sk_sleep by a call to this function.
Needed for a future RCU conversion. sk_sleep wont be a field directly

Since IPVS now has partial IPv6 support, this patch moves IPVS from
net/ipv4/ipvs to net/netfilter/ipvs. It's a result of:
$ git mv net/ipv4/ipvs net/netfilter
and adapting the relevant Kconfigs/Makefiles to the new path.
