====================
ipv6: use rt6i_gateway as nexthop
The following patchset makes sure that rt6i_gateway
contains valid nexthop information in all cases, so that
we can use different nexthop for sending.
The first patch is a simple fix that makes IPVS, TEE,
RAW(hdrincl) and RTF_DYNAMIC(without RTF_GATEWAY) work as
before 3.9. There is a single corner case not solved by
this patch: RAW(hdrincl) or TEE using local address for
nexthop, a silly feature, I guess. In this case we
see zeroes in rt6i_gateway because we get route that is not
cloned. This is solved only with patch 2.
The second patch is an optimization that makes sure
all resulting routes have rt6i_gateway filled, so that we
can avoid the complex ipv6_addr_any() call added to rt6_nexthop()
by patch 1. And it sets rt6i_gateway for local routes, a case
not handled by patch 1.
The third patch uses the new rt6_nexthop() function to fix
the matching of gateways in the same way as commit bbb5823cf742a7
("netfilter: nf_conntrack: fix rt_gateway checks for H.323 helper")
fixes nf_conntrack_h323_main.c for IPv4. Currently, it depends on
the new definition of rt6_nexthop() in patch 2. Actually, if
patch 2 is applied, patch 3 becomes a cosmetic change.
I see the following two alternatives for applying these
patches:
1. Linger patch 2 in net-next to avoid surprises in the upcoming
release. In this case patch 3 can be reworked not to depend on
the new rt6_nexthop() definition in patch 2. I guess this is a
better option, so that patch 2 can be reviewed and tested for
longer time.
2. Include all 3 patches in net tree - more risky because this
is my first attempt to change IPv6.
Here is the situation as handled by patch 2:
In IPv6 the resolved routes are always host routes (/128
with DST_HOST), mostly cloned ones. We allow routes in FIB
to contain rt6i_gateway with zeroes (eg. for local subnets) but
on cloning we can fill the rt6i_gateway field in result.
This works even without this patchset.
There is a single special case where dst is provided as
skb_dst directly without a routing call: icmp6_dst_alloc(). It is a
private dst allocated just for the particular ICMP packet. Patch 2
fills rt6i_gateway in this case, needed for the new rt6_nexthop()
simplification.
The last case is addrconf_dst_alloc(), it can put in
FIB local/anycast routes when addresses are added. Patch 2
needs to fill rt6i_gateway in this case because such routes
are returned without cloning.

Now when rt6_nexthop() can return nexthop address we can use it
for proper nexthop comparison of directly connected destinations.

Make sure rt6i_gateway contains nexthop information in
all routes returned from lookup or when routes are directly
attached to skb for generated ICMP packets.
The effect of this patch should be a faster version of
rt6_nexthop() and the consideration of local addresses as
nexthop.

In v3.9 6fd6ce2056de2709 ("ipv6: Do not depend on rt->n in
ip6_finish_output2()." changed the behaviour of ip6_finish_output2()
such that the recently introduced rt6_nexthop() is used
instead of an assigned neighbor.
As rt6_nexthop() prefers rt6i_gateway only for gatewayed
routes this causes a problem for users like IPVS, xt_TEE and
RAW(hdrincl) if they want to use different address for routing
compared to the destination address.
Another case is when redirect can create RTF_DYNAMIC
route without RTF_GATEWAY flag, we ignore the rt6i_gateway
in rt6_nexthop().
Fix the above problems by considering the rt6i_gateway if
present, so that traffic routed to address on local subnet is
not wrongly diverted to the destination address.
Thanks to Simon Horman and Phil Oester for spotting the
problematic commit.
Thanks to Hannes Frederic Sowa for his review and help in testing.

As part of a register dump, the interface pretends to have the identity
of other interfaces of the same physical device in order to perform
HW configuration for them - specifically, it needs to prevent attentions
from generating on those functions as the register dump accesses registers
in common blocks which whose reading might generate an attention.
However, such pretension is unsafe - unlike other flows in which the driver
uses pretend, during register dump there is no guarantee no other HW access
will take place (by other flows). If such access will take place, the HW will
be accessed by the wrong interface, and leave both functions in an incorrect
state.
This patch removes all pretensions from the register dump flow. Instead, it
changes initial configuration of attentions such that no fatal attention will
be generated for other functions as a result of the register dump
(notice however, a debug print claiming an attention from other functions IS
possible during the register dump)

bnx2x has several clients to its DMAE machines - all of them with the exception
of the statistics flow used the same locking mechanisms to synchronize the DMAE
machines' usage.
Since statistics (which are periodically entered) use DMAE without taking the
locks, they may erase the commands which were previously set -
e.g., it may cause a VF to timeout while waiting for a PF answer on the VF-PF
channel as that command header would have been overwritten by the statistics'
header.
This patch makes certain that all flows utilizing DMAE will use the same
API, assuring that the locking scheme will be kept by all said flows.

During a panic, the driver tries to print the Management FW buffer of recent
commands. To do so, the driver reads the address of that buffer from a known
address. If the buffer is unavailable (e.g., PCI reads don't work, MCP is
failing, etc.), the driver will try to access the address it has read, possibly
causing a kernel panic.
This check 'sanitizes' the access, validating the read value is indeed a valid
address inside the management FW's buffers.
The patch also removes a read outside the scope of the buffer, which resulted
in some unrelated chraracters appearing in the log.

When interrupt pacing is enabled, receive/transmit statistics are not

The parent socket is not used inside the L2CAP core anymore. We only lock
it to indirect access through the new_connection() callback. The hold of
the socket lock was moved to the new_connection() callback.
Inside L2CAP core the channel lock is now used in l2cap_le_conn_ready()
and l2cap_conn_ready() to protect the execution of these two functions
during the handling of new incoming connections.
This change remove the socket lock usage from L2CAP core while keeping
the code safe against race conditions.

This simplify and make safer the state change handling inside l2cap_core.c.
we got rid of __l2cap_state_change(). And l2cap_state_change() doesn't lock
the socket anymore, instead the socket is locked inside the ops callback for
state change in l2cap_sock.c.
It makes the code safer because in some we were using a unlocked version,
and now we are calls to l2cap_state_change(), when dealing with sockets, use
the locked version.

In both places that we use the defer callback the socket lock is held for
a indirect sk access inside __l2cap_change_state() and chan->ops->defer(),
all the rest of the code between lock_sock() and release_sock() is
already protected by the channel lock and won't be affected by this
change.
We now use l2cap_change_state(), the locked version of the change state
function, and the defer callback does the locking itself now. This does
not affect other uses of the defer callback.

In the process of removing socket usage from L2CAP we now access the L2CAP
socket from the data member of struct l2cap_chan. For the L2CAP socket
user the data member points to the L2CAP socket.

It is a leftover from the recent effort of remove sk usage from L2CAP
core.

The create_flow/destroy_flow uverbs and the associated extensions to
the user-kernel verbs ABI are under review and are too experimental to
freeze at this point.
So userspace is not exposed to experimental features and an uinstable
ABI, temporarily disable this for v3.12 (with a Kconfig option behind
staging to reenable it if desired).
The feature will be enabled after proper cleanup for v3.13.

The current "fast connectable" feature is BR/EDR-only, so add a proper
check for BR/EDR support before proceeding with the associated HCI

The timeout was not properly converted from msecs
to jiffies. As a result channel transition to
NL80211_DFS_USABLE was delayed depending on
CONFIG_HZ configuration, e.g. HZ=100 would delay
the NOP from 30 minutes to 300 minutes.

The LEGO-wiimote uses a different VID than the Nintendo ID. The device is
technically the same so add the ID.

Since rdev->sched_scan_req is dereferenced outside the
lock protecting it, this might be done at the wrong
time, causing crashes. Move the dereference to where
it should be - inside the RTNL locked section.

It does not make sense to queue retransmitted packets if the
original packet is still in some queue of this host. So add
a check to xdst_queue_output() and drop the packet if the
original packet is not yet sent.
