In general, when DAD detected IPv6 duplicate address, ifp->state

delayed work, the call tree should be like this:

ndisc_recv_ns

     -> addrconf_mod_dad_work
       -> schedule addrconf_dad_work()

addrconf_dad_failure() called with ifp refcont holding but not put.
addrconf_dad_work() call addrconf_dad_stop() without extra holding
refcount. This will not cause any issue normally.

But the race between addrconf_dad_failure() and addrconf_dad_work()
may cause ifp refcount leak and netdevice can not be unregister,

When deleting an IP address from an interface, there is a clean-up of
routes which refer to this local address. However, there was no check to
see that the VRF matched. This meant that deletion wasn't confined to
the VRF it should have been.

To solve this, a new field has been added to fib_info to hold a table
id. When removing fib entries corresponding to a local ip address, this
table id is also used in the comparison.

The table id is populated when the fib_info is created. This was already
done in some places, but not in ip_rt_ioctl(). This has now been fixed.

Right now we use the 'readlock' both for protecting some of the af_unix
IO path and for making the bind be single-threaded.

The two are independent, but using the same lock makes for a nasty
deadlock due to ordering with regards to filesystem locking.  The bind
locking would want to nest outside the VSF pathname locking, but the IO
locking wants to nest inside some of those same locks.

We tried to fix this earlier with commit c845acb3 ("af_unix: Fix
splice-bind deadlock") which moved the readlock inside the vfs locks,
but that caused problems with overlayfs that will then call back into
filesystem routines that take the lock in the wrong order anyway.

Splitting the locks means that we can go back to having the bind lock be
the outermost lock, and we don't have any deadlocks with lock ordering.

This reverts commit c845acb3.

It turns out that it just replaces one deadlock with another one: we can
still get the wrong lock ordering with the readlock due to overlayfs
calling back into the filesystem layer and still taking the vfs locks
after the readlock.

The proper solution ends up being to just split the readlock into two
pieces: the bind lock (taken *outside* the vfs locks) and the IO lock
(taken *inside* the filesystem locks).  The two locks are independent
anyway.

  ip l a type vxlan dstport 4789 id 1 group ff0e::110

However, neither of those really works. In the IPv4 case, the interface
cannot be brought up ("RTNETLINK answers: No such device"). This is because
multicast join will be rejected without the interface being specified.

In the IPv6 case, multicast wil be joined on the first interface found. This
is not what the user wants as it depends on random factors (order of
interfaces).

Note that it's possible to add a local address but it doesn't solve
anything. For IPv4, it's not considered in the multicast join (thus the same
error as above is returned on ifup). This could be added but it wouldn't
help for IPv6 anyway. For IPv6, we do need the interface.

Just reject a configuration that sets multicast address and does not provide
an interface. Nobody can depend on the previous behavior as it never worked.

When PCI error is detected, in some architectures (like PowerPC) a slot
reset is performed - the driver's error handlers are in charge of "disable"
device before the reset, and re-enable it after a successful slot reset.

There are two cases though that another path is taken on the code: if the
slot reset is not successful or if too many errors already happened in the
specific adapter (meaning that possibly the device is experiencing a HW
failure that slot reset is not able to solve), the core PCI error mechanism
(called EEH in PowerPC) will remove the adapter from the system, since it
will consider this as a permanent failure on device. In this case, a path
is taken that leads to bnx2x_chip_cleanup() calling bnx2x_reset_hw(), which
then tries to perform a HW reset on chip. This reset won't succeed since
the HW is in a fault state, which can be seen by multiple messages on
kernel log like below:

	bnx2x: [bnx2x_issue_dmae_with_comp:552(eth1)]DMAE timeout!
	bnx2x: [bnx2x_write_dmae:600(eth1)]DMAE returned failure -1

After some time, the PCI error mechanism gives up on waiting the driver's
correct removal procedure and forcibly remove the adapter from the system.
We can see soft lockup while core PCI error mechanism is waiting for driver
to accomplish the right removal process.

This patch adds a verification to avoid a chip reset whenever the function
is in PCI error state - since this case is only reached when we have a
device being removed because of a permanent failure, the HW chip reset is
not expected to work fine neither is necessary.

Also, as a minor improvement in error path, we avoid the MCP information dump
in case of non-recoverable PCI error (when adapter is about to be removed),
since it will certainly fail.

On ThunderX 88xx pass 2.x chips when TSO is offloaded to HW,
HW posts a CQE for every TSO segment transmitted. Current code

small resulting in SW processing too many CQEs and also at times
frees a SKB which is not yet transmitted.

This patch handles the errata in a different way and eliminates issues
with earlier approach, TSO packet is submitted to HW with post_cqe=0,
so that no CQE is posted upon completion of transmission of TSO packet
but a additional HDR + IMMEDIATE descriptors are added to SQ due to
which a CQE is posted and will have required info to be used while
cleanup in napi. This way only one CQE is posted for a TSO packet.

If DCB is configured on the link partner switch with an

the driver is flagging DCB as disabled.  But, for future DCB
LLDPDUs, the driver was checking if the interface was DCB capable
instead of enabled.  This was causing a kernel panic when LLDP
was enabled/disabled on the link partner switch.

This patch corrects the situation by having the LLDP event handler

In a dual bearer configuration, if the second tipc link becomes
active while the first link still has pending nametable "bulk"
updates, it randomly leads to reset of the second link.

When a link is established, the function named_distribute(),
fills the skb based on node mtu (allows room for TUNNEL_PROTOCOL)
with NAME_DISTRIBUTOR message for each PUBLICATION.
However, the function named_distribute() allocates the buffer by
increasing the node mtu by INT_H_SIZE (to insert NAME_DISTRIBUTOR).
This consumes the space allocated for TUNNEL_PROTOCOL.

When establishing the second link, the link shall tunnel all the
messages in the first link queue including the "bulk" update.
As size of the NAME_DISTRIBUTOR messages while tunnelling, exceeds
the link mtu the transmission fails (-EMSGSIZE).

Thus, the synch point based on the message count of the tunnel
packets is never reached leading to link timeout.

In this commit, we adjust the size of name distributor message so that
they can be tunnelled.
