If no peer actually gets attached (either because create is zero or
the peer allocation fails) we'll trigger a BUG because we
unconditionally do an rt{,6}_peer_ptr() afterwards.
Fix this by guarding it with the proper check.

This patch prepares the namespace support for layer 3 protocol trackers.
Basically, this modifies the following interfaces:
* nf_ct_l3proto_[un]register_sysctl.
* nf_conntrack_l3proto_[un]register.
We add a new nf_ct_l3proto_net is used to get the pernet data of l3proto.
This adds rhe new struct nf_ip_net that is used to store the sysctl header
and l3proto_ipv4,l4proto_tcp(6),l4proto_udp(6),l4proto_icmp(v6) because the
protos such tcp and tcp6 use the same data,so making nf_ip_net as a field
of netns_ct is the easiest way to manager it.
This patch also adds init_net to struct nf_conntrack_l3proto to initial
the layer 3 protocol pernet data.

This patch prepares the namespace support for layer 4 protocol trackers.
Basically, this modifies the following interfaces:
* nf_ct_[un]register_sysctl
* nf_conntrack_l4proto_[un]register
to include the namespace parameter. We still use init_net in this patch
to prepare the ground for follow-up patches for each layer 4 protocol
tracker.
We add a new net_id field to struct nf_conntrack_l4proto that is used
to store the pernet_operations id for each layer 4 protocol tracker.
Note that AF_INET6's protocols do not need to do sysctl compat. Thus,
we only register compat sysctl when l4proto.l3proto != AF_INET6.

We handle NULL in rt{,6}_set_peer but then our caller will try to pass
that NULL pointer into inet_putpeer() which isn't ready for it.
Fix this by moving the NULL check one level up, and then remove the
now unnecessary NULL check from inetpeer_ptr_set_peer().

This implementation can deal with having many inetpeer roots, which is
a necessary prerequisite for per-FIB table rooted peer tables.
Each family (AF_INET, AF_INET6) has a sequence number which we bump
when we get a family invalidation request.
Each peer lookup cheaply checks whether the flush sequence of the
root we are using is out of date, and if so flushes it and updates
the sequence number.

There is zero point to this function.
It's only real substance is to perform an extremely outdated BSD4.2
ICMP check, which we can safely remove. If you really have a MTU
limited link being routed by a BSD4.2 derived system, here's a nickel
go buy yourself a real router.
The other actions of ip_rt_frag_needed(), checking and conditionally
updating the peer, are done by the per-protocol handlers of the ICMP
event.
TCP, UDP, et al. have a handler which will receive this event and
transmit it back into the associated route via dst_ops->update_pmtu().
This simplification is important, because it eliminates the one place
where we do not have a proper route context in which to make an
inetpeer lookup.

We encode the pointer(s) into an unsigned long with one state bit.
The state bit is used so we can store the inetpeer tree root to use
when resolving the peer later.
Later the peer roots will be per-FIB table, and this change works to
facilitate that.

Since it's guarenteed that we will access the inetpeer if we're trying
to do timewait recycling and TCP options were enabled on the
connection, just cache the peer in the timewait socket.
In the future, inetpeer lookups will be context dependent (per routing
realm), and this helps facilitate that as well.

The get_peer method TCP uses is full of special cases that make no
sense accommodating, and it also gets in the way of doing more
reasonable things here.
First of all, if the socket doesn't have a usable cached route, there
is no sense in trying to optimize timewait recycling.
Likewise for the case where we have IP options, such as SRR enabled,
that make the IP header destination address (and thus the destination
address of the route key) differ from that of the connection's
destination address.
Just return a NULL peer in these cases, and thus we're also able to
get rid of the clumsy inetpeer release logic.

There's a lot of places that open-code rt{,6}_get_peer() only because
they want to set 'create' to one. So add an rt{,6}_get_peer_create()

There were also a few spots open-coding plain rt{,6}_get_peer() and
those are transformed here as well.

/proc/net/unix has quadratic behavior, and can hold unix_table_lock for
a while if high number of unix sockets are alive. (90 ms for 200k
sockets...)
We already have a hash table, so its quite easy to use it.
Problem is unbound sockets are still hashed in a single hash slot
(unix_socket_table[UNIX_HASH_TABLE])
This patch also spreads unbound sockets to 256 hash slots, to speedup
both /proc/net/unix and unix_diag.
Time to read /proc/net/unix with 200k unix sockets :
(time dd if=/proc/net/unix of=/dev/null bs=4k)
before : 520 secs
after : 2 secs

commit 5faa5df1fa2024 (inetpeer: Invalidate the inetpeer tree along with
the routing cache) added a race :
Before freeing an inetpeer, we must respect a RCU grace period, and make
sure no user will attempt to increase refcnt.
inetpeer_invalidate_tree() waits for a RCU grace period before inserting
inetpeer tree into gc_list and waking the worker. At that time, no
concurrent lookup can find a inetpeer in this tree.

When NetLabel is not enabled, e.g. CONFIG_NETLABEL=n, and the system
receives a CIPSO tagged packet it is dropped (cipso_v4_validate()
returns non-zero). In most cases this is the correct and desired
behavior, however, in the case where we are simply forwarding the
traffic, e.g. acting as a network bridge, this becomes a problem.
This patch fixes the forwarding problem by providing the basic CIPSO
validation code directly in ip_options_compile() without the need for
the NetLabel or CIPSO code. The new validation code can not perform
any of the CIPSO option label/value verification that
cipso_v4_validate() does, but it can verify the basic CIPSO option
format.
The behavior when NetLabel is enabled is unchanged.

Since commit ad0081e43a
"ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed"
the fragment of packets is incorrect.
because tunnel mode needs IPsec headers and trailer for all fragments,
while on transport mode it is sufficient to add the headers to the
first fragment and the trailer to the last.
so modify mtu and maxfraglen base on ipsec mode and if fragment is first
or last.
with my test,it work well(every fragment's size is the mtu)
and does not trigger slow fragment path.
Changes from v1:
though optimization, mtu_prev and maxfraglen_prev can be delete.
replace xfrm mode codes with dst_entry's new frag DST_XFRM_TUNNEL.
add fuction ip6_append_data_mtu to make codes clearer.

We call the destroy function when a cgroup starts to be removed, such as
by a rmdir event.
However, because of our reference counters, some objects are still
inflight. Right now, we are decrementing the static_keys at destroy()
time, meaning that if we get rid of the last static_key reference, some
objects will still have charges, but the code to properly uncharge them
won't be run.
This becomes a problem specially if it is ever enabled again, because now
new charges will be added to the staled charges making keeping it pretty
much impossible.
We just need to be careful with the static branch activation: since there
is no particular preferred order of their activation, we need to make sure
that we only start using it after all call sites are active. This is
achieved by having a per-memcg flag that is only updated after
static_key_slow_inc() returns. At this time, we are sure all sites are
active.
This is made per-memcg, not global, for a reason: it also has the effect
of making socket accounting more consistent. The first memcg to be
limited will trigger static_key() activation, therefore, accounting. But
all the others will then be accounted no matter what. After this patch,
only limited memcgs will have its sockets accounted.
[akpm@linux-foundation.org: move enum sock_flag_bits into sock.h,
document enum sock_flag_bits,
convert memcg_proto_active() and memcg_proto_activated() to test_bit(),
redo tcp_update_limit() comment to 80 cols]

The ERTM and streaming mode transmit queue must only be accessed while
the L2CAP channel lock is held. Locking the channel before calling
l2cap_chan_send ensures that multiple threads cannot simultaneously
manipulate the queue when sending and receiving concurrently.
L2CAP channel locking had previously moved to the l2cap_chan struct
instead of the associated socket, so some of the old socket locking
can also be removed in this patch.

Use more common code for ERTM and streaming mode segmentation and
transmission, and begin using skb control block data for delaying
extended or enhanced header generation until just before the packet is
transmitted. This code is also better suited for resegmentation,

In this API, we were using sizeof operator for an array
given as function argument, which is invalid.
However this API is not used anywhere.

Instead of using modular division, the offset can be calculated using
only addition and subtraction. The previous calculation did not work
as intended and was more difficult to understand, involving unsigned
integer underflow and a check for a negative value where one was not
possible.

User-space pass the remote device address type to kernel through
struct sockaddr_l2 what makes the advertising useless. This patch
removes all advertising cache code.

In order to establish a LE connection we need the address type
information. User-space already pass this information to kernel
through struct sockaddr_l2.
This patch adds the dst_type parameter to l2cap_chan_connect so we
are able to pass the address type info from user-space down to
hci_conn layer.

This patch adds the dst_type parameter to hci_connect function.
Instead of searching the address type in advertising cache, we
use the dst_type parameter to establish LE connections.
The dst_type is ignored for BR/EDR connection establishment.

This patch adds the address type info to struct sockaddr_l2 so
user-space can inform the remote device address type required
to establish LE connections.
Soon, instead of looking the advertising cache up to discover the
address type, we'll use this address type info to establish LE
connections.

This patch moves address type macros to bluetooth.h since they will be
used by management interface and Bluetooth socket interface. It also
replaces the macro prefix MGMT_ADDR_ by BDADDR_.
