Implement the VF stats gathering via the kernel via ndo_get_vf_stats().
The driver will show per-VF stats in the output of the
ip -s link show dev <PF> command.

The virtchannel interface was repeating a lot of strings
and wasting storage space in the kernel. There was also
inconsistent messages for the same thing. Consolidate all
those messages and bit checks into a couple of helper functions.
Also, reduce stack space usage by simplifying getting the pointer
to the pf using a helper.

In situations where we alloc and free memory within the same function do
not use the devm_* variants; use regular alloc and free functions. Remove
any unused vars if there are no usages after these changes.
Also, replace an allocate and copy with kmemdup() and remove an
unnecessary memset() to 0 after a kzalloc().

Currently ice_clear_vsi_promisc() detects if the VLAN ID sent is not 0
and sets the recipe_id to ICE_SW_LKUP_PROMISC_VLAN in that case and
ICE_SW_LKUP_PROMISC if the VLAN_ID is 0. However this doesn't allow VLAN
0 promiscuous rules to be removed, but they can be added. Fix this by
checking if the promisc_mask contains ICE_PROMISC_VLAN_RX or
ICE_PROMISC_VLAN_TX. This change was made to match what is being done
for ice_set_vsi_promisc().

Currently there can be a case where a DCB map is applied and there are
more interrupt vectors (vsi->num_q_vectors) than Rx queues (vsi->num_rxq)
and Tx queues (vsi->num_txq). If we try to set coalesce settings in this
case it will report a false failure. Fix this by checking if vector index
is valid with respect to the number of Tx and Rx queues configured.

It is wrong to set PF disable state flag for all VFs when freeing VF
resources - Instead, we should set VF disable state flag for each VF with
its resources being returned to the device. Right now, all VF opcodes,
mailbox communication to clear its resources as well fails - since we
already indicate that PF is in disable state, with all VFs not active. In
addition, we don't need to notify VF that PF is intending to reset it, if
it is already in disabled state.

In the case of an invalid virtchannel request the driver
would return uninitialized data to the VF from the PF stack
which is a bug. Fix by initializing the stack variable
earlier in the function before any return paths can be taken.

Currently when adding/deleting vlans in ice_vc_process_vlan_msg()
we are calling ice_vsi_manage_vlan_stripping() to enable/disable
when adding and deleting a VLAN respectively. This is wrong
because adding/deleting VLANs has nothing to do with configuring
VLAN stripping. VLAN stripping is configured through the
following VIRTCHNL operations:
VIRTCHNL_OP_ENABLE_VLAN_STRIPPING
VIRTCHNL_OP_DISABLE_VLAN_STRIPPING
Unfortunately we can't just remove this because then stripping
will never be configured on VF initialization. Fix this by
adding a new function that initializes (disables/enables) VLAN
stripping for the VF based on the device supported capabilities.
This allows us to remove the call to
ice_vsi_manage_vlan_stripping() in ice_vc_process_vlan_msg().

Currently if the host disables VLAN offloads on the VF by
not setting the VIRTCHNL_VF_OFFLOAD_VLAN capability bit
we will still honor VF VLAN configuration messages over
VIRTCHNL. These messages (i.e. enable/disable VLAN stripping
and VLAN filtering) should be blocked when the feature
is not supported. Fix that by adding a helper function to
determine if the VF is allowed to do VLAN operations based
on the host's VF configuration.
Also, mirror the VF communicated capabilities in the host's
VF configuration.

ipmb_poll() is defined as returning 'unsigned int' but the
.poll method is declared as returning '__poll_t', a bitwise type.
Fix this by using the proper return type and using the EPOLL
constants instead of the POLL ones, as required for __poll_t.

Call napi_disable() twice would cause dead lock. There are three situations
may result in the issue.
1. rtl8152_pre_reset() and set_carrier() are run at the same time.
2. Call rtl8152_set_tunable() after rtl8152_close().
3. Call rtl8152_set_ringparam() after rtl8152_close().
For #1, use the same solution as commit 84811412464d ("r8152: Re-order
napi_disable in rtl8152_close"). For #2 and #3, add checking the flag
of IFF_UP and using napi_disable/napi_enable during mutex.

End.DT6 behavior makes use of seg6_lookup_nexthop() function which drops
all packets that are destined to be locally processed. However, DT* should
be able to deliver decapsulated packets that are destined to local
addresses. Function seg6_lookup_nexthop() is also used by DX6, so in order
to maintain compatibility I created another routing helper function which
is called seg6_lookup_any_nexthop(). This function is able to take into
account both packets that have to be processed locally and the ones that
are destined to be forwarded directly to another machine. Hence,
seg6_lookup_any_nexthop() is used in DT6 rather than seg6_lookup_nexthop()
to allow local delivery.

In commit a82055af5959 ("netfilter: nft_payload: add VLAN offload
support"), VLAN fields in struct flow_dissector_key_vlan were unionized
with the intention of introducing another field that covered the whole TCI
header. However without a wrapping struct the subfields end up sharing the
same bits. As a result, "tc filter add ... flower vlan_id 14" specifies not
only vlan_id, but also vlan_priority.
Fix by wrapping the individual VLAN fields in a struct.

It is observed that TIPC service binding order will not be kept in the
publication event report to user if the service is subscribed after the
bindings.
For example, services are bound by application in the following order:
Server: bound port A to {18888,66,66} scope 2
Server: bound port A to {18888,33,33} scope 2
Now, if a client subscribes to the service range (e.g. {18888, 0-100}),
it will get the 'TIPC_PUBLISHED' events in that binding order only when
the subscription is started before the bindings.
Otherwise, if started after the bindings, the events will arrive in the
opposite order:
Client: received event for published {18888,33,33}
Client: received event for published {18888,66,66}
For the latter case, it is clear that the bindings have existed in the
name table already, so when reported, the events' order will follow the
order of the rbtree binding nodes (- a node with lesser 'lower'/'upper'
range value will be first).
This is correct as we provide the tracking on a specific service status
(available or not), not the relationship between multiple services.
However, some users expect to see the same order of arriving events
irrespective of when the subscription is issued. This turns out to be
easy to fix. We now add functionality to ensure that publication events
always are issued in the same temporal order as the corresponding
bindings were performed.
v2: replace the unnecessary macro - 'publication_after()' with inline
function.
v3: reuse 'time_after32()' instead of reinventing the same exact code.

Once udp stack has set the UDP_SKB_IS_STATELESS flag, later skb free
assumes all skb head state has been dropped already.
This will leak the extension memory in case the skb has extensions other
than the ipsec secpath, e.g. bridge nf data.
To fix this, set the UDP_SKB_IS_STATELESS flag only if we don't have
extensions or if the extension space can be free'd.

Let's limit shrinking to !ZONE_DEVICE so we can fix the current code.
We should never try to touch the memmap of offline sections where we
could have uninitialized memmaps and could trigger BUGs when calling
page_to_nid() on poisoned pages.
There is no reliable way to distinguish an uninitialized memmap from an
initialized memmap that belongs to ZONE_DEVICE, as we don't have
anything like SECTION_IS_ONLINE we can use similar to
pfn_to_online_section() for !ZONE_DEVICE memory.
E.g., set_zone_contiguous() similarly relies on pfn_to_online_section()
and will therefore never set a ZONE_DEVICE zone consecutive. Stopping
to shrink the ZONE_DEVICE therefore results in no observable changes,
besides /proc/zoneinfo indicating different boundaries - something we
can totally live with.
Before commit d0dc12e86b31 ("mm/memory_hotplug: optimize memory
hotplug"), the memmap was initialized with 0 and the node with the right
value. So the zone might be wrong but not garbage. After that commit,
both the zone and the node will be garbage when touching uninitialized
memmaps.
Toshiki reported a BUG (race between delayed initialization of
ZONE_DEVICE memmaps without holding the memory hotplug lock and
concurrent zone shrinking).

This BUG is also mitigated by this commit, where we for now stop to
shrink the ZONE_DEVICE zone until we can do it in a safe and clean way.

Commit 56e94ea132bb ("fs: ocfs2: fix possible null-pointer dereferences
in ocfs2_xa_prepare_entry()") introduces a regression that fail to
create directory with mount option user_xattr and acl. Actually the
reported NULL pointer dereference case can be correctly handled by
loc->xl_ops->xlo_add_entry(), so revert it.

When we passed some location in DESTDIR, install_headers called
do_install with DESTDIR as part of the second argument.
But do_install is again using '$(DESTDIR_SQ)$2', so as a result the
headers were installed in a location $DESTDIR/$DESTDIR.
In my testing I passed DESTDIR=/home/sudip/test and the headers were
installed in: /home/sudip/test/home/sudip/test/usr/include/traceevent.
Lets remove DESTDIR from the second argument of do_install so that the
headers are installed in the correct location.
