We've run into a problem where our device is attached
to a Virtual Machine and the use of the new pci_set_vpd_size()
API doesn't help.  The VM kernel has been informed that
the accesses are okay, but all of the actual VPD Capability
Accesses are trapped down into the KVM Hypervisor where it
goes ahead and imposes the silent denials.

The right idea is to follow the kernel.org
commit 1c7de2b4 ("PCI: Enable access to non-standard VPD for
Chelsio devices (cxgb3)") which Alexey Kardashevskiy authored
to establish a PCI Quirk for our T3-based adapters. This commit
extends that PCI Quirk to cover Chelsio T4 devices and later.

The advantage of this approach is that the VPD Size gets set early
in the Base OS/Hypervisor Boot and doesn't require that the cxgb4
driver even be available in the Base OS/Hypervisor.  Thus PF4 can
be exported to a Virtual Machine and everything should work.

In fib_nh_match(), if output interface or gateway are passed in
the FIB configuration, we don't have to check next hops of
multipath routes to conclude whether we have a match or not.

However, we might still have routes with different realms
matching the same output interface and gateway configuration,
and this needs to cause the match to fail. Otherwise the first
route inserted in the FIB will match, regardless of the realms:

 # ip route add 1.1.1.1 dev eth0 table 1234 realms 1/2
 # ip route append 1.1.1.1 dev eth0 table 1234 realms 3/4
 # ip route list table 1234
 1.1.1.1 dev eth0 scope link realms 1/2
 1.1.1.1 dev eth0 scope link realms 3/4
 # ip route del 1.1.1.1 dev ens3 table 1234 realms 3/4
 # ip route list table 1234
 1.1.1.1 dev ens3 scope link realms 3/4

whereas route with realms 3/4 should have been deleted instead.

Explicitly check for fc_flow passed in the FIB configuration
(this comes from RTA_FLOW extracted by rtm_to_fib_config()) and
fail matching if it differs from nh_tclassid.

The handling of RTA_FLOW for multipath routes later in
fib_nh_match() is still needed, as we can have multiple RTA_FLOW
attributes that need to be matched against the tclassid of each
next hop.

v2: Check that fc_flow is set before discarding the match, so
    that the user can still select the first matching rule by
    not specifying any realm, as suggested by David Ahern.

tipc: Fix missing RTNL lock protection during setting link properties

At present it's unsafe to configure link properties through netlink
as the entire setting process is not under RTNL lock protection. Now
TIPC supports two different sets of netlink APIs at the same time, and
they share the same set of backend functions to configure bearer,
media and net properties. In order to solve the missing RTNL issue,
we have to make the whole __tipc_nl_compat_doit() protected by RTNL,
which means any function called within it cannot take RTNL any more.
So in the series we first introduce the following new functions which
doesn't hold RTNl lock:

 - __tipc_nl_bearer_disable()
 - __tipc_nl_bearer_enable()
 - __tipc_nl_bearer_set()
 - __tipc_nl_media_set()
 - __tipc_nl_net_set()

Meanwhile, __tipc_nl_compat_doit() has been reconstructed to minimize
the time of holding RTNL lock.

Changes in v4:
 - Per suggestion of Kirill Tkhai, divided original big one patch into
   seven small ones so that they can be easily reviewed.

Changes in v3:
 - Optimized return method of __tipc_nl_bearer_enable() regarding
   the comments from David M and Kirill Tkhai
 - Moved the allocations of memory in __tipc_nl_compat_doit() out
   of RTNL lock to minimize the time of holding RTNL lock according
   to the suggestion of Kirill Tkhai.

Changes in v2:
 - The whole operation of setting bearer/media properties has been
   protected under RTNL, as per feedback from David M.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Currently when user changes link properties, TIPC first checks if
user's command message contains media name or bearer name through
tipc_media_find() or tipc_bearer_find() which is protected by RTNL
lock. But when tipc_nl_compat_link_set() conducts the checking with
the two functions, it doesn't hold RTNL lock at all, as a result,
the following complaints were reported:

This reverts commit aa136d0c.

As I previously[1] pointed out this implementation of XDP_REDIRECT is
wrong.  XDP_REDIRECT is a facility that must work between different
NIC drivers.  Another NIC driver can call ndo_xdp_xmit/nicvf_xdp_xmit,
but your driver patch assumes payload data (at top of page) will
contain a queue index and a DMA addr, this is not true and worse will
likely contain garbage.

Given you have not fixed this in due time (just reached v4.16-rc1),
the only option I see is a revert.

netif_set_real_num_tx_queues() can be called when netdev is up.
That usually happens when user requests change of number of
channels/rings with ethtool -L.  The procedure for changing
the number of queues involves resetting the qdiscs and setting
dev->num_tx_queues to the new value.  When the new value is
lower than the old one, extra care has to be taken to ensure
ordering of accesses to the number of queues vs qdisc reset.

Currently the queues are reset before new dev->num_tx_queues
is assigned, leaving a window of time where packets can be
enqueued onto the queues going down, leading to a likely
crash in the drivers, since most drivers don't check if TX
skbs are assigned to an active queue.

This fixes a compile problem of some user space applications by not
including linux/libc-compat.h in uapi/if_ether.h.

linux/libc-compat.h checks which "features" the header files, included
from the libc, provide to make the Linux kernel uapi header files only
provide no conflicting structures and enums. If a user application mixes
kernel headers and libc headers it could happen that linux/libc-compat.h
gets included too early where not all other libc headers are included
yet. Then the linux/libc-compat.h would not prevent all the
redefinitions and we run into compile problems.
This patch removes the include of linux/libc-compat.h from
uapi/if_ether.h to fix the recently introduced case, but not all as this
is more or less impossible.

It is no problem to do the check directly in the if_ether.h file and not
in libc-compat.h as this does not need any fancy glibc header detection
as glibc never provided struct ethhdr and should define
__UAPI_DEF_ETHHDR by them self when they will provide this.

The following test program did not compile correctly any more:
