net: bridge: reject DSA-enabled master netdevices as bridge members
DSA-enabled master network devices with a switch tagging protocol should
strip the protocol specific format before handing the frame over to
higher layer.
When adding such a DSA master network device as a bridge member, we go
through the following code path when receiving a frame:
__netif_receive_skb_core
-> first ptype check against ptype_all is not returning any
handler for this skb
-> check and invoke rx_handler:
-> deliver frame to the bridge layer: br_handle_frame
DSA registers a ptype handler with the fake ETH_XDSA ethertype, which is
called *after* the bridge-layer rx_handler has run. br_handle_frame()
tries to parse the frame it received from the DSA master network device,
and will not be able to match any of its conditions and jumps straight
at the end of the end of br_handle_frame() and returns
RX_HANDLER_CONSUMED there.
Since we returned RX_HANDLER_CONSUMED, __netif_receive_skb_core() stops
RX processing for this frame and returns NET_RX_SUCCESS, so we never get
a chance to call our switch tag packet processing logic and deliver
frames to the DSA slave network devices, and so we do not get any
functional bridge members at all.
Instead of cluttering the bridge receive path with DSA-specific checks,
and rely on assumptions about how __netif_receive_skb_core() is
processing frames, we simply deny adding the DSA master network device
(conduit interface) as a bridge member, leaving only the slave DSA
network devices to be bridge members, since those will work correctly in
all circumstances.

net: ipv4: handle DSA enabled master network devices
The logic to configure a network interface for kernel IP
auto-configuration is very simplistic, and does not handle the case
where a device is stacked onto another such as with DSA. This causes the
kernel not to open and configure the master network device in a DSA
switch tree, and therefore slave network devices using this master
network devices as conduit device cannot be open.
This restriction comes from a check in net/dsa/slave.c, which is
basically checking the master netdev flags for IFF_UP and returns
-ENETDOWN if it is not the case.
Automatically bringing-up DSA master network devices allows DSA slave
network devices to be used as valid interfaces for e.g: NFS root booting
by allowing kernel IP autoconfiguration to succeed on these interfaces.
On the reverse path, make sure we do not attempt to close a DSA-enabled
device as this would implicitely prevent the slave DSA network device
from operating.

- Reworked comments against v7, related to checker warning.
- Patch 2/4 that has all of the driver code in v7 is now split into 3
patches based on functionality so that we have 3 smaller patches
review instead of a big patch.
- Patch for MAINTAINER is merged to 2/4 along with netcp core driver
- Separate patch (3/4) for 1G and (4/4) for 10G
- Removed big endian support for initial version (will add it later)
v6->v7
- Fixed some minor documentation error and also modified the netcp driver
to fix the set* functions to include correct le/be macros.
v5->v6
- updated version after incorporating comments [6] from David Miller,
David Laight & Geert Uytterhoeven on v5. I would like get this in
for v3.19 merge window if the latest version is acceptable.
v4->v5
- Sorry to spin v5 quickly but I missed few check-patch warnings which
were pointed by Joe Perches(thanks). I folded his changes [5] along with
few more check-patch warning fixes. I would like get this in for v3.18
merge window if David is happy with this version.
v3->v4
- Couple of fixes in in error path as pointed [4] out by David. Rest of
the patches are unchanged from v3.
v2->v3
- Update v3 after incorporating Jamal and David Miller's comment/suggestion
from earlier versions [1] [2]. After per the discussion here [3], the
controversial custom exports have been dropped now. And for future
future offload support additions, we will plug into generic frameworks
as an when they are available.

====================
netns: allow to identify peer netns
The goal of this serie is to be able to multicast netlink messages with an
attribute that identify a peer netns.
This is needed by the userland to interpret some information contained in
netlink messages (like IFLA_LINK value, but also some other attributes in case
of x-netns netdevice (see also
http://thread.gmane.org/gmane.linux.network/315933/focus=316064 and
http://thread.gmane.org/gmane.linux.kernel.containers/28301/focus=4239)).
Ids of peer netns can be set by userland via a new rtnl cmd RTM_NEWNSID. When
the kernel needs an id for a peer (for example when advertising a new x-netns
interface via netlink), if the user didn't allocate an id, one will be
automatically allocated.
These ids are stored per netns and are local (ie only valid in the netns where
they are set). To avoid allocating an int for each peer netns, I use
idr_for_each() to retrieve the id of a peer netns. Note that it will be possible
to add a table (struct net -> id) later to optimize this lookup if needed.
Patch 1/4 introduces the rtnetlink API mechanism to set and get these ids.
Patch 2/4 and 3/4 implements an example of how to use these ids when advertising
information about a x-netns interface.
And patch 4/4 shows that the netlink messages can be symetric between a GET and
a SET.
iproute2 patches are available, I can send them on demand.
Here is a small screenshot to show how it can be used by userland.

netlink: make nlmsg_end() and genlmsg_end() void
Contrary to common expectations for an "int" return, these functions
return only a positive value -- if used correctly they cannot even
return 0 because the message header will necessarily be in the skb.
This makes the very common pattern of
if (genlmsg_end(...) < 0) { ... }
be a whole bunch of dead code. Many places also simply do
return nlmsg_end(...);
and the caller is expected to deal with it.
This also commonly (at least for me) causes errors, because it is very
common to write
if (my_function(...))
/* error condition */
and if my_function() does "return nlmsg_end()" this is of course wrong.
Additionally, there's not a single place in the kernel that actually
needs the message length returned, and if anyone needs it later then
it'll be very easy to just use skb->len there.
Remove this, and make the functions void. This removes a bunch of dead
code as described above. The patch adds lines because I did
- return nlmsg_end(...);
+ nlmsg_end(...);
+ return 0;
I could have preserved all the function's return values by returning
skb->len, but instead I've audited all the places calling the affected
functions and found that none cared. A few places actually compared
the return value with <= 0 in dump functionality, but that could just
be changed to < 0 with no change in behaviour, so I opted for the more
efficient version.
One instance of the error I've made numerous times now is also present
in net/phonet/pn_netlink.c in the route_dumpit() function - it didn't
check for <0 or <=0 and thus broke out of the loop every single time.
I've preserved this since it will (I think) have caused the messages to
userspace to be formatted differently with just a single message for
every SKB returned to userspace. It's possible that this isn't needed
for the tools that actually use this, but I don't even know what they
are so couldn't test that changing this behaviour would be acceptable.

1) Generate one notification including all attributes from master and self:
But, I don't think it will work, because both master and self may use
the same attributes/policy. Cannot pack the same set of attributes in a
single notification from both master and slave (duplicate attributes).
2) Generate one notification from master and the other notification from
self (This seems to be ideal):
For master: the master driver will send notification (bridge in this
example)
For self: the self driver will send notification (rocker in the above
example. It can use helpers from rtnetlink.c to do so. Like the
ndo_dflt_bridge_getlink api).
This patch implements 2) (leaving the 'rtnl_bridge_notify' around to be used
with 'self').
v1->v2 :
- rtnl_bridge_notify is now called only for self,
so, remove 'BRIDGE_FLAGS_SELF' check and cleanup a few things
- rtnl_bridge_dellink used to always send a RTM_NEWLINK msg
earlier. So, I have changed the notification from br_dellink to
go as RTM_NEWLINK

Intel Wired LAN Driver Updates 2015-01-16
This series contains updates to i40e and i40evf.
This series is a little bit larger than normal because two of the patches are
version bumps.
Shannon provides tweaks to i40e and i40evf to keep the firmware, software
and silicon validation in line together by removing unused and
deprecated code, adding define for iSCSI and fix queue mask size. Fix
i40e so we do not give up in the reset/rebuild process if DCB setup
fails, just handle it the same as in the probe setup. Cleans up PTP
log messages by removing the use of __func__ as we are not using that
any longer and removes the netdev name, since that can change and can
be misleading. Adds struct size checks to indirect and command
structs that were left out previously. Added admin queue API updates
(LLDP control, OEM OCSD and OCBB commands).
Kevin increases ASQ timeout for scenarios with multi-function devices.
Carolyn fixes a problem where the interrupts descriptions from the MSIx
configuration were truncating the needed bus info, which makes it hard
to distinguish configurations from port to port. Increased the string
buffer size in order to allow the full data to be displayed.
Sravanthi cleans up the dump stats string from debugfs.
Jacob updates i40e to only enable the PTP interrupt in PFs which have PTP
enabled, instead of blindly enabling the PTP interrupt flags for all PFs.
Also updated i40e so that we do not do Tx or Rx timestamps if we do not
have PTP enabled. Added the same check against pf->ptp_rx as we have
in Rx timestamp code path because it is possible that the user can
configure only Tx hardware timestamping so we do not want to check for
Rx timestamp hang since the software won't be handling them.
Neerav updates the driver to disable firmware LLDP agent for NICs with
a firmware version lower than v4.3 and added a message when this happens.
Adds parsing and reporting of iSCSI capability for a given device or
function, as well as adding support for iSCSI partition type with DCB
in NPAR mode.
v2:
- Dropped patch 10 "i40e: clean up PTP log messages" based on feedback
from David Laight and David Miller
- Split up the original patch 13 "i40e: AQ API updates for new commands"
into 2 patches (now #12 & #13) based on feedback from Or Gerlitz

Hence, the patch enables querying of DCB configuration in MFP mode and

rhashtable: Fix race in rhashtable_destroy() and use regular work_struct
When we put our declared work task in the global workqueue with
schedule_delayed_work(), its delay parameter is always zero.
Therefore, we should define a regular work in rhashtable structure
instead of a delayed work.
By the way, we add a condition to check whether resizing functions
are NULL before cancelling the work, avoiding to cancel an
uninitialized work.
Lastly, while we wait for all work items we submitted before to run
to completion with cancel_delayed_work(), ht->mutex has been taken in
rhashtable_destroy(). Moreover, cancel_delayed_work() doesn't return
until all work items are accomplished, and when work items are
scheduled, the work's function - rht_deferred_worker() will be called.
However, as rht_deferred_worker() also needs to acquire the lock,
deadlock might happen at the moment as the lock is already held before.
So if the cancel work function is moved out of the lock covered scope,
this will avoid the deadlock.
