Add a couple of helpers to resolve negotiated flow control. Two helpers
are provided:
- linkmode_resolve_pause() which takes the link partner and local
advertisements, and decodes whether we should enable TX or RX pause
at the MAC. This is useful outside of phylib, e.g. in phylink.
- phy_get_pause(), which returns the TX/RX enablement status for the
current negotiation results of the PHY.
This allows us to centralise the flow control resolution, rather than
spreading it around.

Without this modification and if CRYPTO is not selected, we have this
warning:
WARNING: unmet direct dependencies detected for CRYPTO_LIB_SHA256
Depends on [n]: CRYPTO [=n]
Selected by [y]:
- MPTCP [=y] && NET [=y] && INET [=y]
MPTCP selects CRYPTO_LIB_SHA256 which seems to depend on CRYPTO. CRYPTO
is now selected to avoid this issue.
Even though the config system prints that warning, it looks like
sha256.c is compiled and linked even without CONFIG_CRYPTO. Since MPTCP
will end up needing CONFIG_CRYPTO anyway in future commits -- currently
in preparation for net-next -- we propose to add it now to fix the
warning.
The dependency in the config system comes from the fact that
CRYPTO_LIB_SHA256 is defined in "lib/crypto/Kconfig" which is sourced
from "crypto/Kconfig" only if CRYPTO is selected.

This patchset fixes lockdep problem in bonding interface
1. The first patch is to add missing netdev_update_lockdep_key().
After bond_release(), netdev_update_lockdep_key() should be called.
But both ioctl path and attribute path don't call
netdev_update_lockdep_key().
This patch adds missing netdev_update_lockdep_key().
2. The second patch is to export netdev_next_lower_dev_rcu symbol.
netdev_next_lower_dev_rcu() is useful to implement the function,
which is to walk their all lower interfaces.
This patch is actually a preparing patch for the third patch.
3. The last patch is to fix lockdep waring in bond_get_stats().
The stats_lock uses a dynamic lockdep key.
So, after "nomaster" operation, updating the dynamic lockdep key
routine is needed. but it doesn't

- Drop a patch("bonding: do not collect slave's stats")
- Add new patches

But, there would be cases that couldn't be covered by given

So, some modules would want to implement own function,
which is to walk all lower interfaces.
In the next patch, netdev_next_lower_dev_rcu() will be used.

This patchset is intended to reduce the number of extra system calls
imposed by TCP receive zerocopy. For ping-pong RPC style workloads,
this patchset has demonstrated a system call reduction of about 30%
when coupled with userspace changes.
For applications using epoll, returning sk_err along with the result
of tcp receive zerocopy could remove the need to call
recvmsg()=-EAGAIN after a spurious wakeup.
Consider a multi-threaded application using epoll. A thread may awaken
with EPOLLIN but another thread may already be reading. The
spuriously-awoken thread does not necessarily know that another thread
'won'; rather, it may be possible that it was woken up due to the
presence of an error if there is no data. A zerocopy read receiving 0
bytes thus would need to be followed up by recvmsg to be sure.
Instead, we return sk_err directly with zerocopy, so the application
can avoid this extra system call.

It turns out there's an easy way to get packets queued up while still
having an MTU of zero, and that's via persistent keep alive. This commit
makes sure that in whatever condition, we don't wind up dividing by
zero. Note that an MTU of zero for a wireguard interface is something
quasi-valid, so I don't think the correct fix is to limit it via
min_mtu. This can be reproduced easily with:
ip link add wg0 type wireguard
ip link add wg1 type wireguard
ip link set wg0 up mtu 0
ip link set wg1 up
wg set wg0 private-key <(wg genkey)
wg set wg1 listen-port 1 private-key <(wg genkey) peer $(wg show wg0 public-key)
wg set wg0 peer $(wg show wg1 public-key) persistent-keepalive 1 endpoint 127.0.0.1:1
However, while min_mtu=0 seems fine, it makes sense to restrict the
max_mtu. This commit also restricts the maximum MTU to the greatest
number for which rounding up to the padding multiple won't overflow a
signed integer. Packets this large were always rejected anyway
eventually, due to checks deeper in, but it seems more sound not to even
let the administrator configure something that won't work anyway.
We use this opportunity to clean up this function a bit so that it's
clear which paths we're expecting.

Yet another checksum offload compatibility issue was found.
The known issue is that AQC HW marks tcp packets with 0xFFFF checksum
as invalid (1). This is workarounded in driver, passing all the suspicious
packets up to the stack for further csum validation.
Another HW problem (2) is that it hides invalid csum of LRO aggregated
packets inside of the individual descriptors. That was workarounded
by forced scan of all LRO descriptors for checksum errors.
However the scan logic was joint for both LRO and multi-descriptor
packets (jumbos). And this causes the issue.
We have to drop LRO packets with the detected bad checksum
because of (2), but we have to pass jumbo packets to stack because of (1).
When using windows tcp partner with jumbo frames but with LSO disabled
driver discards such frames as bad checksummed. But only LRO frames
should be dropped, not jumbos.
On such a configurations tcp stream have a chance of drops and stucks.

This series improves the semantics behind the way virtio-vsock server

point is to ensure each request from the client is quickly processed

Whenever the server side of vsock is binding to the socket, but not

what happens when the server is not even started.
This new test runs the server side so that it binds to the socket
without ever listening to it. The client side will try to connect and
should receive an ECONNRESET error.
This new test provides a way to validate the previously introduced patch
for making sure the server side will always answer with a RST packet in
case the client requested a new connection.

Whenever the vsock backend on the host sends a packet through the RX
queue, it expects an answer on the TX queue. Unfortunately, there is one
case where the host side will hang waiting for the answer and might
effectively never recover if no timeout mechanism was implemented.
This issue happens when the guest side starts binding to the socket,
which insert a new bound socket into the list of already bound sockets.
At this time, we expect the guest to also start listening, which will
trigger the sk_state to move from TCP_CLOSE to TCP_LISTEN. The problem
occurs if the host side queued a RX packet and triggered an interrupt
right between the end of the binding process and the beginning of the
listening process. In this specific case, the function processing the
packet virtio_transport_recv_pkt() will find a bound socket, which means
it will hit the switch statement checking for the sk_state, but the
state won't be changed into TCP_LISTEN yet, which leads the code to pick
the default statement. This default statement will only free the buffer,
while it should also respond to the host side, by sending a packet on
its TX queue.
In order to simply fix this unfortunate chain of events, it is important
that in case the default statement is entered, and because at this stage
we know the host side is waiting for an answer, we must send back a
packet containing the operation VIRTIO_VSOCK_OP_RST.
One could say that a proper timeout mechanism on the host side will be
enough to avoid the backend to hang. But the point of this patch is to
ensure the normal use case will be provided with proper responsiveness
when it comes to establishing the connection.

Johannes Berg says:
====================
A few big new things:
* 802.11 frame encapsulation offload support
* more HE (802.11ax) support, including some for 6 GHz band
* powersave in hwsim, for better testing
Of course as usual there are various cleanups and small fixes.

After commit 71130f2997 ("vxlan: fix tos value before xmit") we start
strict vxlan xmit tos value by RT_TOS(), which limits the tos value less
than 0x1E. With current value 0x40 the test will failed with "v1: Expected
to capture 10 packets, got 0". So let's choose a smaller tos value for
testing.

It looks like on PLBU_OUT_OF_MEM interrupt we need to resume from where we
stopped, i.e. new PLBU heap start is old end. Also update end address
in GP frame to grow heap on 2nd and subsequent out of memory interrupts.

Because of autosuspend, at91ether_start is called with clocks disabled.
Ensure that pm_runtime doesn't suspend the interface as soon as it is
opened as there is no pm_runtime support is the other relevant parts of the
platform support for at91rm9200.

In 709772e6e0, RT_TABLE_COMPAT was added to
allow legacy software to deal with routing table numbers >= 256, but the
same change to FIB rule queries was overlooked.
