868d13ac81 [NETNS]: Pass fib_rules_ops into default_pref method.
fib_rules_ops contains operations and the list of configured rules. ops will
become per/namespace soon, so we need them to be known in the default_pref
callback.

f8c26b8d58 [NETNS]: Add netns parameter to fib_rules_(un)register.
The patch extends the different fib rules API in order to pass the
network namespace pointer. That will allow to access the different
tables from a namespace relative object. As usual, the pointer to the
init_net variable is passed as parameter so we don't break the
network.

7c76509d0d [NETNS][IPV6]: Make mld_max_msf readonly in other namespaces.
The mld_max_msf protects the system with a maximum allowed multicast
source filters. Making this variable per namespace can be potentially
an problem if someone inside a namespace set it to a big value, that
will impact the whole system including other namespaces.

I don't see any benefits to have it per namespace for now, so in order
to keep a directory entry in a newly created namespace, I make it
read-only when we are not in the initial network namespace.

The ip6_frags is moved to the network namespace structure.  Because

Each network namespace wants its own set of sysctl value, eg. we

The initialization of the sysctl for the ipv6 protocol is changed to a

This patch add a network namespace subsystem for the af_inet6 module.
It does nothing right now, but one of its purpose is to receive the
different variables for sysctl in order to initialize them.

When the sysctl variable will be moved to the network namespace
structure, they will be no longer initialized as global static
variables, so we must find a place to initialize them. Because the
sysctl can be disabled, it has no sense to store them in the
sysctl_net_ipv6 file.

b3fd3ffe39 [NETFILTER]: Use the ctl paths instead of hand-made analogue
The conntracks subsystem has a similar infrastructure
to maintain ctl_paths, but since we already have it
on the generic level, I think it's OK to switch to
using it.

So, basically, this patch just replaces the ctl_table-s
with ctl_path-s, nf_register_sysctl_table with
register_sysctl_paths() and removes no longer needed code.

After this the net/netfilter/nf_sysctl.c file contains
the paths only.

4cec72c890 [TIPC]: Use tipc_port_unlock
The file net/tipc/port.c takes a lock using the function tipc_port_lock and
then releases the lock sometimes using tipc_port_unlock and sometimes using

spin_unlock_bh, but it seems cleaner to use it everywhere.

df26e7ea04 rc80211_pid should respect fixed rates.
I would argue that mac80211 should handle fixed rates outside the rate
control code, which would also allow them to take effect immediately
instead of during the rate control callback, but this is pretty close
to correct.

4b475898ec mac80211: better rate control algorithm selection
This patch changes mac80211's Kconfig/Makefile to:
 * select between the PID and the SIMPLE rate control
   algorithm as default
 * always allow tri-state for the rate control algorithms,
   building those that are selected 'y' into the mac80211
   module (if that is a module, otherwise all into the kernel)
 * force the default rate control algorithm to be built into
   mac80211

It also makes both rate control algorithms proper modules again
with MODULE_LICENSE etc.

Only if EMBEDDED is the user allowed to select "NONE" as default
which will cause no algorithm to be selected, this will work
only when the driver brings one itself (e.g. iwlwifi drivers).

69f817b654 mac80211: Restore rx.fc before every invocation of ieee80211_invoke_rx_handlers
This patch fixes a problem with rx handling on multiple interfaces. Especially
when using hardware-scanning and a wireless driver (i.e. iwlwifi) which is
able to receive data while scanning.

The rx handlers can modify the skb and the frame control field (see
ieee80211_rx_h_remove_qos_control) but since every interface gets its own
copy of the skb each should get its own copy of rx.fc too.

In my case the wlan0-interface did not remove the qos-control from the frame
because the corresponding flag in rx.fc was already removed while processing
the frame on the master interface. Therefore somehow corrupted frames were
passed to the userspace.

67b23219ce [BLUETOOTH]: Use sockfd_put()
The function sockfd_lookup uses fget on the value that is stored in
the file field of the returned structure, so fput should ultimately be
applied to this value.  This can be done directly, but it seems better
to use the specific macro sockfd_put, which does the same thing.

The problem was fixed using the following semantic patch.
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
expression s;
@@

   s = sockfd_lookup(...)
   ...
+  sockfd_put(s);
?- fput(s->file);
// </smpl>

WANG Cong
64c31b3f76 [XFRM] xfrm_policy_destroy: Rename and relative fixes.
Since __xfrm_policy_destroy is used to destory the resources
allocated by xfrm_policy_alloc. So using the name
__xfrm_policy_destroy is not correspond with xfrm_policy_alloc.
Rename it to xfrm_policy_destroy.

And along with some instances that call xfrm_policy_alloc
but not using xfrm_policy_destroy to destroy the resource,
fix them.
