Although the driver works on big-endian hardware, Sparse generates a lot
of warnings. Many of these are the result of incorrect coding of these

Refactor how we add new filters to firmware to avoid a race condition
that can occur due to removing filters from the hash temporarily.
To understand the race condition, suppose that you have a number of MAC
filters, but have not yet added any VLANs. Now, add two VLANs in rapid
succession. A possible resulting flow would look something like the
following:
(1) lock hash for add VLAN
(2) add the new MAC/VLAN combos for each current MAC filter
(3) unlock hash
(4) lock hash for filter sync
(5) notice that we have a VLAN, so prepare to update all MAC filters
with VLAN=-1 to be VLAN=0.
(6) move NEW and REMOVE filters to temporary list
(7) unlock hash
(8) lock hash for add VLAN
(9) add new MAC/VLAN combos. Notice that no MAC filters are currently in
the hash list, so we don't add any VLANs <--- BUG!
(10) unlock hash
(11) sync the temporary lists to firmware
(12) lock hash for post-sync
(13) move the temporary elements back to the main list
....
Because we take filters out of the main hash into temporary lists, we
introduce a narrow window where it is possible that other callers to the
list will not see some of the filters which were previously added but
have not yet been finalized. This results in sometimes dropping VLAN
additions, and could also result in failing to add a MAC address on the
newly added VLAN.
One obvious way to avoid this race condition would be to lock the entire
firmware process. Unfortunately this does not work because adminq
firmware commands take a mutex which results in a sleep while atomic
BUG(). So, we can't use the simplest approach.
An alternative approach is to simply not remove the filters from the
hash list while adding. Instead, add an i40e_new_mac_filter structure
which we will use to track added filters. This avoids the need to remove
the filter from the hash list. We'll store a pointer to the original
i40e_mac_filter, along with our own copy of the state.
We won't update the state directly, so as to avoid race with other code
that may modify the state while under the lock. We are safe to read
f->macaddr and f->vlan since these only change in two locations. The
first is on filter creation, which must have already occurred. The
second is inside i40e_correct_vlan_filters which was previously run
after creation of this object and can't be run again until after. Thus,
we should be safe to read the MAC address and VLAN while outside the
lock.
We also aren't going to run into a use-after-free issue because the only
place where we free filters is when they are marked FAILED or when we
remove them inside the sync subtask. Since the subtask has its own
critical flag to prevent duplicate runs, we know this won't happen. We
also know that the only location to transition a filter from NEW to
FAILED is inside the subtask also, so we aren't worried about that
either.
Use the wrapper i40e_new_mac_filter for additions, and once we've
finalized the addition to firmware, we will update the filter state
inside a lock, and then free the wrapper structure.
In order to avoid a possible race condition with filter deletion, we
won't update the original filter state unless it is still
I40E_FILTER_NEW when we finish the firmware sync.
This approach is more complex, but avoids race conditions related to
filters being temporarily removed from the list. We do not need the same
behavior for deletion because we always unconditionally removed the
filters from the list regardless of the firmware status.

Fix a bug where we modified the mac_filter_hash while outside a lock,
when handling addition of broadcast filters.
Normally, we add filters to firmware by batching the additions into
lists and issuing 1 update for every few filters. Broadcast filters are
handled differently, by instead setting the broadcast promiscuous mode
flags. In order to make sure the 1<->1 mapping of filters in our
addition array lined up with filters in the hlist tmp_add_list, we had
to remove the filter and move it back to the main hash. However, we
didn't do this under lock, which could cause consistency problems for
the list.
Fix this by updating i40e_update_filter_state logic so that it knows to
avoid broadcast filters. This ensures that we don't have to remove the
filter separately, and can put it back using the normal flow.

The intent of this message was to indicate to a user that we might have
missed a timestamp event for a valid packet. The original method of
detecting the missed events relied on waiting until all 4 registers were
filled.
A recent commit d55458c0cd7a5 ("i40e: replace PTP Rx timestamp hang
logic") replaced this logic with much better detection
scheme that could detect a stalled Rx timestamp register even when other
registers were still functional.
The new logic means that a message will be displayed almost as soon as
a timestamp for a dropped frame occurs. This new logic highlights that
the hardware will attempt timestamp for frames which it later decides to
drop. The most prominent example is when a multicast PTP frame is
received on a multicast address that we are not subscribed to.
Because the hardware initiates the Rx timestamp as soon as possible, it
will latch an RXTIME register, but then drop the packet.
This results in users being confused by the message as they are not
expecting to see dropped timestamp messages unless their application
also indicates that timestamps were missing.
Resolve this by reducing the severity and frequency of the displayed
message. We now only print the message if 3 or 4 of the RXTIME registers
are stalled and get cleared within the same watchdog event. This ensures
that the common case does not constantly display the message.
Additionally, since the message is likely not as meaningful to most
users, reduce the message to a dev_dbg instead of a dev_warn.
Users can still get a count of the number of timestamps dropped by
reading the ethtool statistics value, if necessary.

This patch reduces the size of struct i40e_rx_buffer by one pointer,
and makes the i40e driver a little more consistent with the igb driver
in terms of packets that span buffers.
We do this by moving the skb field from struct i40e_rx_buffer to
struct i40e_ring. We pass the skb we already have (or NULL if we
don't) to i40e_fetch_rx_buffer(), which skips the skb allocation if we
already have one for this packet.

Dmitry reported uses after free in qdisc code [1]
The problem here is that ops->init() can return an error.
qdisc_create_dflt() then call ops->destroy(),
while qdisc_create() does _not_ call it.
Four qdisc chose to call their own ops->destroy(), assuming their caller
would not.
This patch makes sure qdisc_create() calls ops->destroy()
and fixes the four qdisc to avoid double free.
