Commit e5dadc65f9 ("ppp: Fix false xmit recursion detect with two ppp
devices") dropped the xmit_recursion counter incrementation in
ppp_channel_push() and relied on ppp_xmit_process() for this task.
But __ppp_channel_push() can also send packets directly (using the
.start_xmit() channel callback), in which case the xmit_recursion
counter isn't incremented anymore. If such packets get routed back to
the parent ppp unit, ppp_xmit_process() won't notice the recursion and
will call ppp_channel_push() on the same channel, effectively creating
the deadlock situation that the xmit_recursion mechanism was supposed
to prevent.
This patch re-introduces the xmit_recursion counter incrementation in
ppp_channel_push(). Since the xmit_recursion variable is now part of
the parent ppp unit, incrementation is skipped if the channel doesn't
have any. This is fine because only packets routed through the parent
unit may enter the channel recursively.
Finally, we have to ensure that pch->ppp is not going to be modified
while executing ppp_channel_push(). Instead of taking this lock only
while calling ppp_xmit_process(), we now have to hold it for the full
ppp_channel_push() execution. This respects the ppp locks ordering
which requires locking ->upl before ->downl.

When Ethernet frames span mulitple URBs, the netdev buffer memory
pointed to by the asix_rx_fixup_info structure remains allocated
during the time gap between the 2 executions of asix_rx_fixup_internal().
This means that if ax88772_unbind() is called within this time
gap to free the memory of the parent private data structure then
a memory leak of the part filled netdev buffer memory will occur.
Therefore, create a new function asix_rx_fixup_common_free() to
free the memory of the netdev buffer and add a call to
asix_rx_fixup_common_free() from inside ax88772_unbind().
Consequently when an unbind occurs part way through receiving
an Ethernet frame, the netdev buffer memory that is holding part
of the received Ethernet frame will now be freed.

There is a risk that the members of the structure asix_rx_fixup_info
become unsynchronised leading to the possibility of a malfunction.
For example, rx->split_head was not being set to false after an
error was detected so potentially could cause a malformed 32-bit
Data header word to be formed.
Therefore add function reset_asix_rx_fixup_info() to reset all the
members of asix_rx_fixup_info so that future processing will start
with known initial conditions.
Also, if (skb->len != offset) becomes true then call
reset_asix_rx_fixup_info() so that the processing of the next URB
starts with known initial conditions. Without the call, the check
does nothing which potentially could lead to a malfunction
when the next URB is processed.
In addition, for robustness, call reset_asix_rx_fixup_info() before
every error path's "return 0". This ensures that the next URB is
processed from known initial conditions.

In asix_rx_fixup_internal() there is a risk that rx->ax_skb gets
reused after passing the Ethernet frame into the network stack via
usbnet_skb_return().
The risks include:
a) asynchronously freeing rx->ax_skb after passing the netdev buffer
to the NAPI layer which might corrupt the backlog queue.
b) erroneously reusing rx->ax_skb such as calling skb_put_data() multiple
times which causes writing off the end of the netdev buffer.
Therefore add a defensive rx->ax_skb = NULL after usbnet_skb_return()
so that it is not possible to free rx->ax_skb or to apply
skb_put_data() too many times.

Pin 23 on South bridge does not belong to the rgmii group. It belongs to
a separate group which can have 3 functions.
Due to this the fix also have to update the way the functions are
managed. Until now each groups used NB_FUNCS(which was 2) functions. For
the mpp23, 3 functions are available but it is the only group which needs
it, so on the loop involving NB_FUNCS an extra test was added to handle
only the functions added.
The bug was visible with the merge of the commit 07d065abf9 "arm64:
dts: marvell: armada-3720-db: Add vqmmc regulator for SD slot", the gpio
regulator used the gpio 23, due to this the whole rgmii group was setup
to gpio which broke the Ethernet support on the Armada 3720 DB
board. Thanks to this patch, the UHS SD cards (which need the vqmmc)
_and_ the Ethernet work again.

The existing sub channel code did not wait for all the sub-channels
to completely initialize. This could lead to race causing crash
in napi_netif_del() from bad list. The existing code would send
an init message, then wait only for the initial response that
the init message was received. It thought it was waiting for
sub channels but really the init response did the wakeup.
The new code keeps track of the number of open channels and
waits until that many are open.
Other issues here were:
* host might return less sub-channels than was requested.
* the new init status is not valid until after init was completed.

This fixes a problem where the system gets stuck in a loop
unable to wakeup via power button in s2idle.
The problem happens because:
- press power button:
- system emits 0xc0 (power press), event ignored
- system emits 0xc1 (power release), event processed,
emited as KEY_POWER
- set wakeup_mode to true
- system goes to s2idle
- press power button
- system emits 0xc0 (power press), wakeup_mode is true,
system wakes
- system emits 0xc1 (power release), event processed,
emited as KEY_POWER
- system goes to s2idle again
To avoid this situation, process the presses (which matches what
intel-hid does too).

Uverbs device should be cleaned up only when there is no
potential usage of.
As part of ib_uverbs_remove_one which might be triggered upon reset flow
the device reference count is decreased as expected and leave the final
cleanup to the FDs that were opened.
Current code increases reference count upon opening a new command FD and
decreases it upon closing the file. The event FD is opened internally
and rely on the command FD by taking on it a reference count.
In case that the command FD was closed and just later the event FD we
may ensure that the device resources as of srcu are still alive as they
are still in use.
Fixing the above by moving the reference count decreasing to the place
where the command FD is really freed instead of doing that when it was
just closed.

Currently while resolving IP address to MAC address single delayed work
is used for resolving multiple such resolve requests. This singled work
is essentially performs two tasks.
(a) any retry needed to resolve and
(b) it executes the callback function for all completed requests
While work is executing callbacks, any new work scheduled on for this
workqueue is lost because workqueue has completed looking at all pending
requests and now looking at callbacks, but work is still under
execution. Any further retry to look at pending requests in
process_req() after executing callbacks would lead to similar race
condition (may be reduce the probably further but doesn't eliminate it).
Retrying to enqueue work that from queue_req() context is not something
rest of the kernel modules have followed.
Therefore fix in this patch utilizes kernel facility to enqueue multiple
work items to a workqueue. This ensures that no such requests
gets lost in synchronization. Request list is still maintained so that
rdma_cancel_addr() can unlink the request and get the completion with
error sooner. Neighbour update event handling continues to be handled in
same way as before.
Additionally process_req() work entry cancels any pending work for a
request that gets completed while processing those requests.
Originally ib_addr was ST workqueue, but it became MT work queue with
patch of [1]. This patch again makes it similar to ST so that
neighbour update events handler work item doesn't race with
other work items.
In one such below trace, (though on 4.5 based kernel) it can be seen
that process_req() never executed the callback, which is likely for an
event that was schedule by queue_req() when previous callback was
getting executed by workqueue.

Each multicast group (MID) stores a bitmap of ports to which a packet
should be forwarded to in case an MDB entry associated with the MID is
hit.
Since the initial introduction of IGMP snooping in commit 3a49b4fde2
("mlxsw: Adding layer 2 multicast support") the driver didn't correctly
free these multicast groups upon ungraceful situations such as the
removal of the upper bridge device or module removal.
The correct way to fix this is to associate each MID with the bridge
ports member in it and then drop the reference in case the bridge port
is destroyed, but this will result in a lot more code and will be fixed
in net-next.
For now, upon module removal, traverse the MID list and release each
one.

Some operations in the bridge driver such as MDB deletion are preformed
in an atomic context and thus deferred to a process context by the
switchdev infrastructure.
Therefore, by the time the operation is performed by the underlying
device driver it's possible the bridge port context is already gone.
This is especially true for removal flows, but theoretically can also be
invoked during addition.
Remove the warnings in such situations and return normally.
