d658f8a0e6 ipv4: ipmr: remove net pointer from struct mfc_cache
Now that cache entries in unres_queue don't need to be distinguished by their
network namespace pointer anymore, we can remove it from struct mfc_cache
add pass the namespace as function argument to the functions that need it.

e258beb22f ipv4: ipmr: move unres_queue and timer to per-namespace data
The unres_queue is currently shared between all namespaces. Following patches
will additionally allow to create multiple multicast routing tables in each
namespace. Having a single shared queue for all these users seems to excessive,
move the queue and the cleanup timer to the per-namespace data to unshare it.

As a side-effect, this fixes a bug in the seq file iteration functions: the
first entry returned is always from the current namespace, entries returned
after that may belong to any namespace.

0f87b1dd01 net: fib_rules: decouple address families from real address families
Decouple the address family values used for fib_rules from the real
address families in socket.h. This allows to use fib_rules for
code that is not a real address family without increasing AF_MAX/NPROTO.

Values up to 127 are reserved for real address families and map directly
to the corresponding AF value, values starting from 128 are for other
uses. rtnetlink is changed to invoke the AF_UNSPEC dumpit/doit handlers
for these families.

b6c6712a42 net: sk_dst_cache RCUification
With latest CONFIG_PROVE_RCU stuff, I felt more comfortable to make this
work.

sk->sk_dst_cache is currently protected by a rwlock (sk_dst_lock)

This rwlock is readlocked for a very small amount of time, and dst
entries are already freed after RCU grace period. This calls for RCU
again :)

This patch converts sk_dst_lock to a spinlock, and use RCU for readers.

__sk_dst_get() is supposed to be called with rcu_read_lock() or if
socket locked by user, so use appropriate rcu_dereference_check()
condition (rcu_read_lock_held() || sock_owned_by_user(sk))

This patch avoids two atomic ops per tx packet on UDP connected sockets,
for example, and permits sk_dst_lock to be much less dirtied.

2e8e18ef52 tcp: Set CHECKSUM_UNNECESSARY in tcp_init_nondata_skb
Back in commit 04a0551c87
("loopback: Drop obsolete ip_summed setting") we stopped
setting CHECKSUM_UNNECESSARY in the loopback xmit.

This is because such a setting was a lie since it implies that the
checksum field of the packet is properly filled in.

Instead what happens normally is that CHECKSUM_PARTIAL is set and
skb->csum is calculated as needed.

But this was only happening for TCP data packets (via the
skb->ip_summed assignment done in tcp_sendmsg()).  It doesn't
happen for non-data packets like ACKs etc.

Fix this by setting skb->ip_summed in the common non-data packet
constructor.  It already is setting skb->csum to zero.

But this reminds us that we still have things like ip_output.c's
ip_dev_loopback_xmit() which sets skb->ip_summed to the value
CHECKSUM_UNNECESSARY, which Herbert's patch teaches us is not
valid.  So we'll have to address that at some point too.

unconnected socket bound to (INADDR_ANY, 1701) and one connected socket per
tunnel after parameter negotiation.

ddd0451fc8 x.25 attempts to negotiate invalid throughput
The current X.25 code has some bugs in throughput negotiation:

   1. It does negotiation in all cases, usually there is no need
   2. It incorrectly attempts to negotiate the throughput class in one
      direction only.  There are separate throughput classes for input
      and output and if either is negotiated both mist be negotiates.

This is bug https://bugzilla.kernel.org/show_bug.cgi?id=15681

This bug was first reported by Daniel Ferenci to the linux-x25 mailing
list on 6/8/2004, but is still present.

The current (2.6.34) x.25 code doesn't seem to know that the X.25
throughput facility includes two values, one for the required
throughput outbound, one for inbound.

This causes it to attempt to negotiate throughput 0x0A, which is
throughput 9600 inbound and the illegal value "0" for inbound
throughput.

Because of this some X.25 devices (e.g. Cisco 1600) refuse to connect
to Linux X.25.

The following patch fixes this behaviour.  Unless the user specifies a
required throughput it does not attempt to negotiate.  If the user
does not specify a throughput it accepts the suggestion of the remote
X.25 system.  If the user requests a throughput then it validates both
the input and output throughputs and correctly negotiates them with
the remote end.

80c802f307 xfrm: cache bundles instead of policies for outgoing flows
__xfrm_lookup() is called for each packet transmitted out of
system. The xfrm_find_bundle() does a linear search which can
kill system performance depending on how many bundles are
required per policy.

This modifies __xfrm_lookup() to store bundles directly in
the flow cache. If we did not get a hit, we just create a new
bundle instead of doing slow search. This means that we can now
get multiple xfrm_dst's for same flow (on per-cpu basis).

fe1a5f031e flow: virtualize flow cache entry methods
This allows to validate the cached object before returning it.
It also allows to destruct object properly, if the last reference
was held in flow cache. This is also a prepartion for caching
bundles in the flow cache.

In return for virtualizing the methods, we save on:
- not having to regenerate the whole flow cache on policy removal:
  each flow matching a killed policy gets refreshed as the getter
  function notices it smartly.
- we do not have to call flow_cache_flush from policy gc, since the
  flow cache now properly deletes the object if it had any references

3dc9fef67f 9p: saving negative to unsigned char
Saving -EINVAL as unsigned char truncates the high bits and changes it
into 234 instead of -22.  This breaks the test for "if (ret == -EINVAL)"
in parse_opts().

6d96d3ab7a 9p: Make sure we are able to clunk the cached fid on umount
dcache prune happen on umount. So we cannot mark the client
satus disconnect. That will prevent a 9p call to the server

7bddd0db62 l2tp: unmanaged L2TPv3 tunnels fixes
Followup to commit 789a4a2c 
(l2tp: Add support for static unmanaged L2TPv3 tunnels)

One missing init in l2tp_tunnel_sock_create() could access random kernel
memory, and a bit field should be unsigned.

1f8438a853 icmp: Account for ICMP out errors
When ip_append() fails because of socket limit or memory shortage,
increment ICMP_MIB_OUTERRORS counter, so that "netstat -s" can report
these errors.

LANG=C netstat -s | grep "ICMP messages failed"
    0 ICMP messages failed

For IPV6, implement ICMP6_MIB_OUTERRORS counter as well.

# grep Icmp6OutErrors /proc/net/dev_snmp6/*
/proc/net/dev_snmp6/eth0:Icmp6OutErrors                   	0
/proc/net/dev_snmp6/lo:Icmp6OutErrors                   	0
