XFRM can deal with SYNACK messages, sent while listener socket
is not locked. We add proper rcu protection to __xfrm_sk_clone_policy()
and xfrm_sk_policy_lookup()
This might serve as the first step to remove xfrm.xfrm_policy_lock
use in fast path.

We will soon switch sk->sk_policy[] to RCU protection,
as SYNACK packets are sent while listener socket is not locked.
This patch simply adds RCU grace period before struct xfrm_policy
freeing, and the corresponding rcu_head in struct xfrm_policy.

TCP SYNACK messages might now be attached to request sockets.
XFRM needs to get back to a listener socket.
Adds new helpers that might be used elsewhere :
sk_to_full_sk() and sk_const_to_full_sk()
Note: We also need to add RCU protection for xfrm lookups,
now TCP/DCCP have lockless listener processing. This will
be addressed in separate patches.

Remove the dst_entries_init/destroy calls for xfrm4 and xfrm6 dst_ops
templates; their dst_entries counters will never be used. Move the
xfrm dst_ops initialization from the common xfrm/xfrm_policy.c to
xfrm4/xfrm4_policy.c and xfrm6/xfrm6_policy.c, and call dst_entries_init
and dst_entries_destroy for each net namespace.
The ipv4 and ipv6 xfrms each create dst_ops template, and perform
dst_entries_init on the templates. The template values are copied to each
net namespace's xfrm.xfrm*_dst_ops. The problem there is the dst_ops
pcpuc_entries field is a percpu counter and cannot be used correctly by
simply copying it to another object.
The result of this is a very subtle bug; changes to the dst entries
counter from one net namespace may sometimes get applied to a different
net namespace dst entries counter. This is because of how the percpu
counter works; it has a main count field as well as a pointer to the
percpu variables. Each net namespace maintains its own main count
variable, but all point to one set of percpu variables. When any net
namespace happens to change one of the percpu variables to outside its
small batch range, its count is moved to the net namespace's main count
variable. So with multiple net namespaces operating concurrently, the
dst_ops entries counter can stray from the actual value that it should
be; if counts are consistently moved from one net namespace to another
(which my testing showed is likely), then one net namespace winds up
with a negative dst_ops count while another winds up with a continually
increasing count, eventually reaching its gc_thresh limit, which causes
all new traffic on the net namespace to fail with -ENOBUFS.

The policies are organized into list by priority ascent of policy,
so it is unnecessary to continue to loop the policy if the priority
of current looped police is larger than or equal priority which is
from the policy_bydst list.

expects that behavior.
Since a recent commit, xfrm_lookup() may also be called by xfrm_lookup_route(),
which expects the opposite.

For a long time we couldn't actually use __xfrm_policy_link in
xfrm_policy_insert because the latter wanted to do hashing at
a specific position.
Now that __xfrm_policy_link no longer does hashing it can now
be safely used in xfrm_policy_insert to kill some duplicate code,
finally reuniting general policies with socket policies.

Back in 2003 when I added policy expiration, I half-heartedly
did a clean-up and renamed xfrm_sk_policy_link/xfrm_sk_policy_unlink
to __xfrm_policy_link/__xfrm_policy_unlink, because the latter
could be reused for all policies. I never actually got around
to using __xfrm_policy_link for non-socket policies.
Later on hashing was added to all xfrm policies, including socket
policies. In fact, we don't need hashing on socket policies at
all since they're always looked up via a linked list.
This patch restores xfrm_sk_policy_link/xfrm_sk_policy_unlink
as wrappers around __xfrm_policy_link/__xfrm_policy_unlink so
that it's obvious we're dealing with socket policies.
This patch also removes hashing from __xfrm_policy_link as for
now it's only used by socket policies which do not need to be
hashed. Ironically this will in fact allow us to use this helper
for non-socket policies which I shall do later.

Currently we genarate a queueing route if we have matching policies
but can not resolve the states and the sysctl xfrm_larval_drop is
disabled. Here we assume that dst_output() is called to kill the
queued packets. Unfortunately this assumption is not true in all
cases, so it is possible that these packets leave the system unwanted.
We fix this by generating queueing routes only from the
route lookup functions, here we can guarantee a call to
dst_output() afterwards.

Enable to specify local and remote prefix length thresholds for the
policy hash table via a netlink XFRM_MSG_NEWSPDINFO message.
prefix length thresholds are specified by XFRMA_SPD_IPV4_HTHRESH and
XFRMA_SPD_IPV6_HTHRESH optional attributes (struct xfrmu_spdhthresh).
example:
struct xfrmu_spdhthresh thresh4 = {
.lbits = 0;
.rbits = 24;
};
struct xfrmu_spdhthresh thresh6 = {
.lbits = 0;
.rbits = 56;
};
struct nlmsghdr *hdr;
struct nl_msg *msg;
msg = nlmsg_alloc();
hdr = nlmsg_put(msg, NL_AUTO_PORT, NL_AUTO_SEQ, XFRMA_SPD_IPV4_HTHRESH, sizeof(__u32), NLM_F_REQUEST);
nla_put(msg, XFRMA_SPD_IPV4_HTHRESH, sizeof(thresh4), &thresh4);
nla_put(msg, XFRMA_SPD_IPV6_HTHRESH, sizeof(thresh6), &thresh6);
nla_send_auto(sk, msg);
The numbers are the policy selector minimum prefix lengths to put a
policy in the hash table.
- lbits is the local threshold (source address for out policies,
destination address for in and fwd policies).
- rbits is the remote threshold (destination address for out
policies, source address for in and fwd policies).
The default values are:
XFRMA_SPD_IPV4_HTHRESH: 32 32
XFRMA_SPD_IPV6_HTHRESH: 128 128
Dynamic re-building of the SPD is performed when the thresholds values
are changed.
The current thresholds can be read via a XFRM_MSG_GETSPDINFO request:
the kernel replies to XFRM_MSG_GETSPDINFO requests by an
XFRM_MSG_NEWSPDINFO message, with both attributes
XFRMA_SPD_IPV4_HTHRESH and XFRMA_SPD_IPV6_HTHRESH.

The idea is an extension of the current policy hashing.
Today only non-prefixed policies are stored in a hash table. This
patch relaxes the constraints, and hashes policies whose prefix
lengths are greater or equal to a configurable threshold.
Each hash table (one per direction) maintains its own set of IPv4 and
IPv6 thresholds (dbits4, sbits4, dbits6, sbits6), by default (32, 32,
128, 128).
Example, if the output hash table is configured with values (16, 24,
56, 64):
ip xfrm policy add dir out src 10.22.0.0/20 dst 10.24.1.0/24 ... => hashed
ip xfrm policy add dir out src 10.22.0.0/16 dst 10.24.1.1/32 ... => hashed
ip xfrm policy add dir out src 10.22.0.0/16 dst 10.24.0.0/16 ... => unhashed
ip xfrm policy add dir out \
src 3ffe:304:124:2200::/60 dst 3ffe:304:124:2401::/64 ... => hashed
ip xfrm policy add dir out \
src 3ffe:304:124:2200::/56 dst 3ffe:304:124:2401::2/128 ... => hashed
ip xfrm policy add dir out \
src 3ffe:304:124:2200::/56 dst 3ffe:304:124:2400::/56 ... => unhashed
The high order bits of the addresses (up to the threshold) are used to
compute the hash key.

All other add functions for lists have the new item as first argument
and the position where it is added as second argument. This was changed
for no good reason in this function and makes using it unnecessary
confusing.
The name was changed to hlist_add_behind() to cause unconverted code to
generate a compile error instead of using the wrong parameter order.

commit 8f0ea0fe3a036a47767f9c80e (snmp: reduce percpu needs by 50%)
reduced snmp array size to 1, so technically it doesn't have to be
an array any more. What's more, after the following commit:
commit 933393f58fef9963eac61db8093689544e29a600
Date: Thu Dec 22 11:58:51 2011 -0600
percpu: Remove irqsafe_cpu_xxx variants
We simply say that regular this_cpu use must be safe regardless of
preemption and interrupt state. That has no material change for x86
and s390 implementations of this_cpu operations. However, arches that
do not provide their own implementation for this_cpu operations will
now get code generated that disables interrupts instead of preemption.
probably no arch wants to have SNMP_ARRAY_SZ == 2. At least after
almost 3 years, no one complains.
So, just convert the array to a single pointer and remove snmp_mib_init()
and snmp_mib_free() as well.

It seems to me that commit ab5f5e8b "[XFRM]: xfrm audit calls" is doing
something strange at xfrm_audit_helper_usrinfo().
If secid != 0 && security_secid_to_secctx(secid) != 0, the caller calls
audit_log_task_context() which basically does
secid != 0 && security_secid_to_secctx(secid) == 0 case
except that secid is obtained from current thread's context.
Oh, what happens if secid passed to xfrm_audit_helper_usrinfo() was
obtained from other thread's context? It might audit current thread's
context rather than other thread's context if security_secid_to_secctx()
in xfrm_audit_helper_usrinfo() failed for some reason.
Then, are all the caller of xfrm_audit_helper_usrinfo() passing either
secid obtained from current thread's context or secid == 0?
It seems to me that they are.
If I didn't miss something, we don't need to pass secid to
xfrm_audit_helper_usrinfo() because audit_log_task_context() will
obtain secid from current thread's context.

In the dst->output() path for ipv4, the code assumes the skb it has to
transmit is attached to an inet socket, specifically via
ip_mc_output() : The sk_mc_loop() test triggers a WARN_ON() when the
provider of the packet is an AF_PACKET socket.
The dst->output() method gets an additional 'struct sock *sk'
parameter. This needs a cascade of changes so that this parameter can
be propagated from vxlan to final consumer.

Inserting a entry into flowcache, or flushing flowcache should be based
on per net scope. The reason to do so is flushing operation from fat
netns crammed with flow entries will also making the slim netns with only
a few flow cache entries go away in original implementation.
Since flowcache is tightly coupled with IPsec, so it would be easier to
put flow cache global parameters into xfrm namespace part. And one last
thing needs to do is bumping flow cache genid, and flush flow cache should
also be made in per net style.

Pull audit update from Eric Paris:
"Again we stayed pretty well contained inside the audit system.
Venturing out was fixing a couple of function prototypes which were
inconsistent (didn't hurt anything, but we used the same value as an
int, uint, u32, and I think even a long in a couple of places).
We also made a couple of minor changes to when a couple of LSMs called
the audit system. We hoped to add aarch64 audit support this go
round, but it wasn't ready.
I'm disappearing on vacation on Thursday. I should have internet
access, but it'll be spotty. If anything goes wrong please be sure to
cc rgb@redhat.com. He'll make fixing things his top priority"

the net-next tree and commit 2f3ea9a95c58 ("xfrm: checkpatch erros with
inline keyword position") from the ipsec-next tree.
The version from net-next can be used, like it is done in linux-next.
1) Checkpatch cleanups, from Weilong Chen.
2) Fix lockdep complaints when pktgen is used with IPsec,
from Fan Du.
3) Update pktgen to allow any combination of IPsec transport/tunnel mode
and AH/ESP/IPcomp type, from Fan Du.
4) Make pktgen_dst_metrics static, Fengguang Wu.
5) Compile fix for pktgen when CONFIG_XFRM is not set,
from Fan Du.

Right now the sessionid value in the kernel is a combination of u32,
int, and unsigned int. Just use unsigned int throughout.

Fix three warnings related to:
net/xfrm/xfrm_policy.c:1644:1: warning: 'inline' is not at beginning of declaration [-Wold-style-declaration]
net/xfrm/xfrm_policy.c:1656:1: warning: 'inline' is not at beginning of declaration [-Wold-style-declaration]
net/xfrm/xfrm_policy.c:1668:1: warning: 'inline' is not at beginning of declaration [-Wold-style-declaration]
Just removing the inline keyword is sufficient as the compiler will
decide on its own about inlining or not.
