Commit e4c7f259c5be ("USB: kaweth.c: use GFP_ATOMIC under spin_lock")
makes sure that kaweth_internal_control_msg() allocates memory with GFP_ATOMIC,
but kaweth_internal_control_msg() also calls usb_start_wait_urb()
that still allocates memory with GFP_NOIO.
The patch fixes usb_start_wait_urb() as well.

Remove the empty array element initializer and size the array with
BOND_OPT_LAST so the compiler will complain if more elements are in
there than should be.
An interesting unwanted side effect of this initializer is that if one
inserts new options into the middle of the array then this initializer
will zero out the option that equals BOND_OPT_TLB_DYNAMIC_LB+1.
Example:
Extend the OPTS enum:
enum {
...
BOND_OPT_TLB_DYNAMIC_LB,
BOND_OPT_LACP_NEW1,
BOND_OPT_LAST
};
Now insert into bond_opts array:
static const struct bond_option bond_opts[] = {
...
[BOND_OPT_LACP_RATE] = { .... unchanged stuff .... },
[BOND_OPT_LACP_NEW1] = { ... new stuff ... },
...
[BOND_OPT_TLB_DYNAMIC_LB] = { .... unchanged stuff ....},
{ } // MARK A
};
Since BOND_OPT_LACP_NEW1 = BOND_OPT_TLB_DYNAMIC_LB+1, the last
initializer (MARK A) will overwrite the contents of BOND_OPT_LACP_NEW1
and can be easily viewed with the crash utility.

====================
tipc: make tipc support namespace
This patchset aims to add net namespace support for TIPC stack.
Currently TIPC module declares the following global resources:
- TIPC network idenfication number
- TIPC node table
- TIPC bearer list table
- TIPC broadcast link
- TIPC socket reference table
- TIPC name service table
- TIPC node address
- TIPC service subscriber server
- TIPC random value
- TIPC netlink
In order that TIPC is aware of namespace, above each resource must be
allocated, initialized and destroyed inside per namespace. Therefore,
the major works of this patchset are to isolate these global resources
and make them private for each namespace. However, before these changes
come true, some necessary preparation works must be first done: convert
socket reference table with generic rhashtable, cleanup core.c and
core.h files, remove unnecessary wrapper functions for kernel timer
interfaces and so on.
It should be noted that commit ##1 ("tipc: fix bug in broadcast
retransmit code") was already submitted to 'net' tree, so please see
below link:
http://patchwork.ozlabs.org/patch/426717/
Since it is prerequisite for the rest of the series to apply, I
prepend them to the series.

Currently tipc module only allows users sitting on "init_net" namespace
to configure it through netlink interface. But now almost each tipc
component is able to be aware of net namespace, so it's time to open
the permission for users residing in other namespaces, allowing them
to configure their own tipc stack instance through netlink interface.

TIPC establishes one subscriber server which allows users to subscribe
their interesting name service status. After tipc supports namespace,
one dedicated tipc stack instance is created for each namespace, and
each instance can be deemed as one independent TIPC node. As a result,
subscriber server must be built for each namespace.

If net namespace is supported in tipc, each namespace will be treated
as a separate tipc node. Therefore, every namespace must own its
private tipc node address. This means the "tipc_own_addr" global
variable of node address must be moved to tipc_net structure to
satisfy the requirement. It's turned out that users also can assign
node address for every namespace.

TIPC name table is used to store the mapping relationship between
TIPC service name and socket port ID. When tipc supports namespace,
it allows users to publish service names only owned by a certain
namespace. Therefore, every namespace must have its private name
table to prevent service names published to one namespace from being
contaminated by other service names in another namespace. Therefore,
The name table global variable (ie, nametbl) and its lock must be
moved to tipc_net structure, and a parameter of namespace must be
added for necessary functions so that they can obtain name table
variable defined in tipc_net structure.

Now tipc socket table is statically allocated as a global variable.
Through it, we can look up one socket instance with port ID, insert
a new socket instance to the table, and delete a socket from the
table. But when tipc supports net namespace, each namespace must own
its specific socket table. So the global variable of socket table
must be redefined in tipc_net structure. As a concequence, a new
socket table will be allocated when a new namespace is created, and
a socket table will be deallocated when namespace is destroyed.

Bearer list defined as a global variable is used to store bearer
instances. When tipc supports net namespace, bearers created in
one namespace must be isolated with others allocated in other
namespaces, which requires us that the bearer list(bearer_list)
must be moved to tipc_net structure. As a result, a net namespace
pointer has to be passed to functions which access the bearer list.

Global variables associated with node table are below:
- node table list (node_htable)
- node hash table list (tipc_node_list)
- node table lock (node_list_lock)
- node number counter (tipc_num_nodes)
- node link number counter (tipc_num_links)
To make node table support namespace, above global variables must be
moved to tipc_net structure in order to keep secret for different
namespaces. As a consequence, these variables are allocated and
initialized when namespace is created, and deallocated when namespace
is destroyed. After the change, functions associated with these
variables have to utilize a namespace pointer to access them. So
adding namespace pointer as a parameter of these functions is the
major change made in the commit.

In order to make tipc socket table aware of namespace, a networking
namespace instance must be passed to tipc_sk_lookup(), allowing it
to look up tipc socket instance with a given port ID from a concrete
socket table. However, as now tipc_sk_timeout() only has one port ID
parameter and is not namespace aware, it's unable to obtain a correct
socket instance through tipc_sk_lookup() just with a port ID,
especially after namespace is completely supported.
If port ID is replaced with socket instance as tipc_sk_timeout()'s
parameter, it's unnecessary to look up socket table. But as the timer
handler - tipc_sk_timeout() is run asynchronously, socket reference
must be held before its timer is launched, and must be carefully
checked to identify whether the socket reference needs to be put or
not when its timer is terminated.

In commit 58dc55f25631178ee74cd27185956a8f7dcb3e32 ("tipc: use generic
SKB list APIs to manage link transmission queue") we replace all list
traversal loops with the macros skb_queue_walk() or
skb_queue_walk_safe(). While the previous loops were based on the
assumption that the list was NULL-terminated, the standard macros
stop when the iterator reaches the list head, which is non-NULL.
In the function bclink_retransmit_pkt() this macro replacement has
lead to a bug. When we receive a BCAST STATE_MSG we unconditionally
call the function bclink_retransmit_pkt(), whether there really is
anything to retransmit or not, assuming that the sequence number
comparisons will lead to the correct behavior. However, if the
transmission queue is empty, or if there are no eligible buffers in
the transmission queue, we will by mistake pass the list head pointer
to the function tipc_link_retransmit(). Since the list head is not a
valid sk_buff, this leads to a crash.
In this commit we fix this by only calling tipc_link_retransmit()
if we actually found eligible buffers in the transmission queue.
