Fan Du 4c4d41f200 xfrm: add LINUX_MIB_XFRMACQUIREERROR statistic counter
When host ping its peer, ICMP echo request packet triggers IPsec
policy, then host negotiates SA secret with its peer. After IKE
installed SA for OUT direction, but before SA for IN direction
installed, host get ICMP echo reply from its peer. At the time
being, the SA state for IN direction could be XFRM_STATE_ACQ,
then the received packet will be dropped after adding
LINUX_MIB_XFRMINSTATEINVALID statistic.

Adding a LINUX_MIB_XFRMACQUIREERROR statistic counter for such
scenario when SA in larval state is much clearer for user than
LINUX_MIB_XFRMINSTATEINVALID which indicates the SA is totally
bad.

Gao feng ece31ffd53 net: proc: change proc_net_remove to remove_proc_entry
proc_net_remove is only used to remove proc entries
that under /proc/net,it's not a general function for
removing proc entries of netns. if we want to remove
some proc entries which under /proc/net/stat/, we still
need to call remove_proc_entry.

this patch use remove_proc_entry to replace proc_net_remove.
we can remove proc_net_remove after this patch.

Gao feng d4beaa66ad net: proc: change proc_net_fops_create to proc_create
Right now, some modules such as bonding use proc_create
to create proc entries under /proc/net/, and other modules
such as ipv4 use proc_net_fops_create.

It looks a little chaos.this patch changes all of
proc_net_fops_create to proc_create. we can remove
proc_net_fops_create after this patch.

Li RongQing bb65a9cb95 xfrm: removes a superfluous check and add a statistic
Remove the check if x->km.state equal to XFRM_STATE_VALID in
xfrm_state_check_expire(), which will be done before call
xfrm_state_check_expire().

add a LINUX_MIB_XFRMOUTSTATEINVALID statistic to record the
outbound error due to invalid xfrm state.

Paul Gortmaker bc3b2d7fb9 net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules
These files are non modular, but need to export symbols using
the macros now living in export.h -- call out the include so
that things won't break when we remove the implicit presence
of module.h from everywhere.

jamal 72032fdbcd xfrm: Introduce LINUX_MIB_XFRMFWDHDRERROR
XFRMINHDRERROR counter is ambigous when validating forwarding
path. It makes it tricky to debug when you have both in and fwd
validation.

Tejun Heo 7d720c3e4f percpu: add __percpu sparse annotations to net
Add __percpu sparse annotations to net.

These annotations are to make sparse consider percpu variables to be
in a different address space and warn if accessed without going
through percpu accessors.  This patch doesn't affect normal builds.

The macro and type tricks around snmp stats make things a bit
interesting.  DEFINE/DECLARE_SNMP_STAT() macros mark the target field
as __percpu and SNMP_UPD_PO_STATS() macro is updated accordingly.  All
snmp_mib_*() users which used to cast the argument to (void **) are
updated to cast it to (void __percpu **).

Masahide NAKAMURA 9472c9ef64 [XFRM]: Fix statistics.
o Outbound sequence number overflow error status
  is counted as XfrmOutStateSeqError.
o Additionaly, it changes inbound sequence number replay
  error name from XfrmInSeqOutOfWindow to XfrmInStateSeqError
  to apply name scheme above.
o Inbound IPv4 UDP encapsuling type mismatch error is wrongly
  mapped to XfrmInStateInvalid then this patch fiex the error
  to XfrmInStateMismatch.
