The function tracer can create a dynamically allocated trampoline that is
called by the function mcount or fentry hook that is used to call the
function callback that is registered. The problem is that the orc undwinder
will bail if it encounters one of these trampolines. This breaks the stack
trace of function callbacks, which include the stack tracer and setting the
stack trace for individual functions.
Since these dynamic trampolines are basically copies of the static ftrace
trampolines defined in ftrace_*.S, we do not need to create new orc entries
for the dynamic trampolines. Finding the return address on the stack will be
identical as the functions that were copied to create the dynamic
trampolines. When encountering a ftrace dynamic trampoline, we can just use
the orc entry of the ftrace static function that was copied for that
trampoline.

Client close is overloaded to handle both un-registration and
netdev down event. On netdev down, i40iw client close is called
which unregisters the RDMA dev and this is too destructive
since the netdev is still registered.
Do not call client close/open on netdev down/up events. Instead
disable the PE TCP_ENA flag during a netdev down event. This
blocks all TCP traffic to the RDMA Protocol Engine. On netdev up,
re-enable the flag.

The driver (and the entire netdev layer for that matter) assumes
that TC0 will always be present in our DCB configuration.
Unfortunately, this isn't always the case. Rather than fail to
configure the VSI, let's go ahead and try to make it work, even
though DCB will end up being disabled by the kernel.
If the driver fails to configure DCB, the driver queries what's
valid, then writes that back to the hardware, always forcing TC0.
This fixes a bug where the driver could fail to adhere to ETS BW
allocations if 8 TCs were configured on the switch.

In VFs, there is a known issue which can cause writebacks
to not occur when interrupts are disabled and there are
less than 4 descriptors resulting in TX timeout. Timeout
can also occur due to lost interrupt.
The current implementation for detecting and recovering
from hung queues in the PF is problematic because it actually
actively encourages lost interrupts. By triggering a SW
interrupt, interrupts are forced on. If we are already in
napi_poll and an interrupt fires, napi_poll will not be
rescheduled and the interrupt is effectively lost; thereby
potentially *causing* hung queues.
This patch checks whether packets are being processed between
every watchdog cycle and determine potential hung queue and
fires triggers SW interrupt only for that particular queue.

This fix solves an issue occurring while calling i40e_led_set function

When a host disables and enables a PF device, all the associated
VFs are removed and added back in. It also generates a PFR which in turn
resets all the connected VFs. This behaviour is different from that of
Linux guest on Linux host. Hence we end up in a situation where there's
a PFR and device removal at the same time. And watchdog doesn't have a
clue about this and schedules a reset_task. This patch adds code to send
signal to reset_task that the device is currently being removed.

Steven Rostedt discovered that the ftrace stack tracer is broken when
it's used with the ORC unwinder. The problem is that objtool is
instructed by the Makefile to ignore the ftrace_64.S code, so it doesn't
generate any ORC data for it.
Fix it by making the asm code objtool-friendly:
- Objtool doesn't like the fact that save_mcount_regs pushes RBP at the
beginning, but it's never restored (directly, at least). So just skip
the original RBP push, which is only needed for frame pointers anyway.
- Annotate some functions as normal callable functions with
ENTRY/ENDPROC.
- Add an empty unwind hint to return_to_handler(). The return address
isn't on the stack, so there's nothing ORC can do there. It will just
punt in the unlikely case it tries to unwind from that code.
With all that fixed, remove the OBJECT_FILES_NON_STANDARD Makefile
annotation so objtool can read the file.

The software tables are made up to mimic the hardware tables to make it

In orangefs_devreq_read, there is a loop which picks an op off the list
of pending ops. If the loop fails to find an op, there is nothing to
read, and it returns EAGAIN. If the op has been given up on, the loop
is restarted via a goto. The bug is that the variable which the found
op is written to is not reinitialized, so if there are no more eligible
ops on the list, the code runs again on the already handled op.
This is triggered by interrupting a process while the op is being copied

Quentin says:
This series tries to improve user experience when eBPF hardware offload
hits error paths at load time. In particular, it introduces netlink
extended ack support in the nfp driver.
To that aim, transmission of the pointer to the extack object is piped
through the `change()` operation of the existing classifiers (patch 1 to
6). Then it is used for TC offload in the nfp driver (patch 8) and in
netdevsim (patch 9, selftest in patch 10). Patch 7 adds a helper to handle
extack messages in the core when TC offload is disabled on the net device.
For completeness extack is propagated for classifiers other than cls_bpf,
but it's up to the drivers to make use of it.
