====================
mptcp: New features for MPTCP sockets and netlink PM
This collection of patches adds MPTCP socket support for a few socket
options, ioctls, and one ancillary data type (specifics for each are
listed below). There's also a patch modifying the netlink MPTCP path
manager API to allow setting the backup flag on a configured interface
using the endpoint ID instead of the full IP address.
Patches 1 & 2: TCP_INQ cmsg and selftests.
Patches 2 & 3: SIOCINQ, OUTQ, and OUTQNSD ioctls and selftests.
Patch 5: Change backup flag using endpoint ID.
Patches 6 & 7: IP_TOS socket option and selftests.
Patches 8-10: TCP_CORK and TCP_NODELAY socket options. Includes a tcp
change to expose __tcp_sock_set_cork() and __tcp_sock_set_nodelay() for
use by MPTCP.

mptcp: support TCP_CORK and TCP_NODELAY
First, add cork and nodelay fields to the mptcp_sock structure
so they can be used in sync_socket_options(), and fill them on setsockopt
while holding the msk socket lock.
Then, on setsockopt set proper tcp_sk(ssk)->nonagle values for subflows
by calling __tcp_sock_set_cork() or __tcp_sock_set_nodelay() on the ssk
while holding the ssk socket lock.
tcp_push_pending_frames() will be invoked on the ssk if a cork was cleared
or nodelay was set. Also set MPTCP_PUSH_PENDING bit by calling
mptcp_check_and_set_pending(). This will lead to __mptcp_push_pending()
being called inside mptcp_release_cb() with new tcp_sk(ssk)->nonagle.
Also add getsockopt support for TCP_CORK and TCP_NODELAY.

net: fix recent csum changes
Vladimir reported csum issues after my recent change in skb_postpull_rcsum()
Issue here is the following:
initial skb->csum is the csum of
[part to be pulled][rest of packet]
Old code:
skb->csum = csum_sub(skb->csum, csum_partial(pull, pull_length, 0));
New code:
skb->csum = ~csum_partial(pull, pull_length, ~skb->csum);
This is broken if the csum of [pulled part]
happens to be equal to skb->csum, because end
result of skb->csum is 0 in new code, instead
of being 0xffffffff
Two first patches add a generic infrastructure, that will be used
to get tracking of refcount increments/decrements.
The general idea is to be able to precisely pair each decrement with
a corresponding prior increment. Both share a cookie, basically
a pointer to private data storing stack traces.
The third patch adds dev_hold_track() and dev_put_track() helpers
(CONFIG_NET_DEV_REFCNT_TRACKER)
Then a series of 20 patches converts some dev_hold()/dev_put()
pairs to new hepers : dev_hold_track() and dev_put_track().
Hopefully this will be used by developpers and syzbot to
root cause bugs that cause netdevice dismantles freezes.
With CONFIG_PCPU_DEV_REFCNT=n option, we were able to detect
some class of bugs, but too late (when too many dev_put()
were happening).
Another series will be sent after this one is merged.
v3: moved NET_DEV_REFCNT_TRACKER to net/Kconfig.debug

net: add net device refcount tracker infrastructure
net device are refcounted. Over the years we had numerous bugs
caused by imbalanced dev_hold() and dev_put() calls.
The general idea is to be able to precisely pair each decrement with
a corresponding prior increment. Both share a cookie, basically
a pointer to private data storing stack traces.
This patch adds dev_hold_track() and dev_put_track().
To use these helpers, each data structure owning a refcount
should also use a "netdevice_tracker" to pair the hold and put.
It can be hard to track where references are taken and released.
In networking, we have annoying issues at device or netns dismantles,
and we had various proposals to ease root causing them.
This patch adds new infrastructure pairing refcount increases
and decreases. This will self document code, because programmers
will have to associate increments/decrements.
This is controled by CONFIG_REF_TRACKER which can be selected
by users of this feature.
This adds both cpu and memory costs, and thus should probably be
used with care.

mlx5-updates-2021-12-02
Misc updates to mlx5 driver
1) Various code cleanups
2) Error path handling fixes of latest features
3) Print more information on pci error handling
4) Dynamically resize flow counters query buffer
====================
The flow counters bulk query buffer is allocated once during
mlx5_fc_init_stats(). For PFs and VFs this buffer usually takes a little
more than 512KB of memory, which is aligned to the next power of 2, to
1MB. For SFs, this buffer is reduced and takes around 128 Bytes.
The buffer size determines the maximum number of flow counters that
can be queried at a time. Thus, having a bigger buffer can improve
performance for users that need to query many flow counters.
There are cases that don't use many flow counters and don't need a big
buffer (e.g. SFs, VFs). Since this size is critical with large scale,
in these cases the buffer size should be reduced.
In order to reduce memory consumption while maintaining query
performance, change the query buffer's allocation scheme to the
following:
- First allocate the buffer with small initial size.
- If the number of counters surpasses the initial size, resize the
buffer to the maximum size.
The buffer only grows and isn't shrank, because users with many flow
counters don't care about the buffer size and we don't want to add
resize overhead if the current number of counters drops.
This solution is preferable to the current one, which is less accurate
and only addresses SFs.

Merge tag 'for-linus-5.16-2' of git://github.com/cminyard/linux-ipmi
Pull IPMI fixes from Corey Minyard:
"Some changes that went in 5.16 had issues. When working on the design
a piece was redesigned and things got missed. And the message type was
not being initialized when it was allocated, resulting in crashes.
In addition, the IPMI driver has had a shutdown issue where it could
still have an item in a system workqueue after it had been shutdown.
Move to a private workqueue to avoid that problem"

Currently autoloading for SPI devices does not use the DT ID table, it
uses SPI modalises. Supporting OF modalises is going to be difficult if
not impractical, an attempt was made but has been reverted, so ensure
that module autoloading works for this driver by adding an id_table
listing the SPI IDs for everything.

net: lan966x: Fix builds for lan966x driver
The lan966x is using the function 'packing' to create/extract the
information for the IFH, that is used to be added in front of the frames
when they are injected/extracted.
Therefore update the Kconfig to select config option 'PACKING' whenever
lan966x driver is enabled.

dt-bindings: net: lan966x: Add additional properties for lan966x
This patch updates the dt-bindings for lan966x switch.
It adds the properties 'additionalProperties' and
'unevaluatedProperties' for ethernet-ports and ports nodes. In this way
it is not possible to add more properties to these nodes.

qed: Enhance rammod debug prints to provide pretty details
Instead of printing numbers of protocol IDs and rammod commands,
enhance debug prints to provide names. s_protocol_types[] and
s_ramrod_cmd_ids arrays[] are added to support along with APIs.
