Now that sys_sysctl is a compatiblity wrapper around /proc/sys
all sysctl strategy routines, and all ctl_name and strategy
entries in the sysctl tables are unused, and can be
revmoed.
In addition neigh_sysctl_register has been modified to no longer
take a strategy argument and it's callers have been modified not
to pass one.

This patch fixes hash collisions in cases where number
of entries have incrementing IP source and destination addresses
from single respective subnets (i.e. 192.168.0.1-172.16.0.1,
192.168.0.2-172.16.0.2, and so on.).

Define three accessors to get/set dst attached to a skb
struct dst_entry *skb_dst(const struct sk_buff *skb)
void skb_dst_set(struct sk_buff *skb, struct dst_entry *dst)
void skb_dst_drop(struct sk_buff *skb)
This one should replace occurrences of :
dst_release(skb->dst)
skb->dst = NULL;
Delete skb->dst field

When kernel inserts a temporary SA for IKE, it uses the wrong hash
value for dst list. Two hash values were calcultated before: one with
source address and one with a wildcard source address.

The change to make xfrm_state objects hash on source address
broke the case where such source addresses are wildcarded.
Fix this by doing a two phase lookup, first with fully specified
source address, next using saddr wildcarded.

When I made ipcomp use frags, I forgot to take out the original
truesize update that was added for pskb_expand_head. As we no
longer expand the head of skb, that update should have been removed.
This bug is not related to the truesize warnings since we only
made it bigger than what it should've been.

An IPsec node speaking IKEv2 MUST accept incoming UDP encapsulated
ESP packets, even if no NAT situation is detected. This is important
if MOBIKE is in use. Some implementation keep the encapsulation
mode if they move out of a NAT situation.

After flush the SPD entries, dump the SPD entries will cause kernel painc.
Used the following commands to reproduct:
- echo 'spdflush;' | setkey -c
- echo 'spdadd 3ffe:501:ffff:ff01::/64 3ffe:501:ffff:ff04::/64 any -P out ipsec \
ah/tunnel/3ffe:501:ffff:ff00:200:ff:fe00:b0b0-3ffe:501:ffff:ff02:200:ff:fe00:a1a1/require;\
spddump;' | setkey -c
- echo 'spdflush; spddump;' | setkey -c
- echo 'spdadd 3ffe:501:ffff:ff01::/64 3ffe:501:ffff:ff04::/64 any -P out ipsec \
ah/tunnel/3ffe:501:ffff:ff00:200:ff:fe00:b0b0-3ffe:501:ffff:ff02:200:ff:fe00:a1a1/require;\
spddump;' | setkey -c
This is because when flush the SPD entries, the SPD entry is not remove
from the list.
This patch fix the problem by remove the SPD entry from the list.

For that make net_core_path[] global, register it to prevent two
