i40e: Fix for VF MAC address 0

After spawning max VFs on a PF, some VFs were not getting resources and
their MAC addresses were 0. This was caused by PF sleeping before flushing
HW registers which caused VIRTCHNL_VFR_VFACTIVE to not be set in time for
VF.

Fix by adding a sleep after hw flush.

i40e: Fix not setting default xps_cpus after reset

During tx rings configuration default XPS queue config is set and
__I40E_TX_XPS_INIT_DONE is locked. __I40E_TX_XPS_INIT_DONE state is
cleared and set again with default mapping only during queues build,
it means after first setup or reset with queues rebuild. (i.e.
ethtool -L <interface> combined <number>) After other resets (i.e.
ethtool -t <interface>) XPS_INIT_DONE is not cleared and those default
maps cannot be set again. It results in cleared xps_cpus mapping
until queues are not rebuild or mapping is not set by user.

Add clearing __I40E_TX_XPS_INIT_DONE state during reset to let
the driver set xps_cpus to defaults again after it was cleared.

xen-netfront: Fix NULL sring after live migration

A NAPI is setup for each network sring to poll data to kernel
The sring with source host is destroyed before live migration and
new sring with target host is setup after live migration.
The NAPI for the old sring is not deleted until setup new sring
with target host after migration. With busy_poll/busy_read enabled,
the NAPI can be polled before got deleted when resume VM.

Previously the xmit function could return -EBUSY without freeing, which

transmitted packets.

sparx5_fdma_xmit and sparx5_inject returns error code, where -EBUSY
indicates TX_BUSY and any other error code indicates dropped.

When there's only one buffer to dma and its length is 4096, then
only one data descriptor is needed to carry it according to current
descriptor definition. So the descriptor type should be `simple`
instead of `gather`, the latter requires more than one descriptor,
otherwise it'll be dropped by application firmware.

Bluetooth: silence a dmesg error message in hci_request.c

On kernel 6.1-rcX, I have been getting the following dmesg error message
on every boot, resume from suspend and rfkill unblock of the Bluetooth
device:

Bluetooth: hci0: HCI_REQ-0xfcf0

After some investigation, it turned out to be caused by
commit dd50a864ffae ("Bluetooth: Delete unreferenced hci_request code")
which modified hci_req_add() in net/bluetooth/hci_request.c to always
print an error message when it is executed. In my case, the function was
executed by msft_set_filter_enable() in net/bluetooth/msft.c, which
provides support for Microsoft vendor opcodes.

As explained by Brian Gix, "the error gets logged because it is using a
deprecated (but still working) mechanism to issue HCI opcodes" [1]. So
this is just a debugging tool to show that a deprecated function is
executed. As such, it should not be included in the mainline kernel.
See for example
commit 771c035372a0 ("deprecate the '__deprecated' attribute warnings entirely and for good")
Additionally, this error message is cryptic and the user is not able to
do anything about it.

Bluetooth: btusb: Add debug message for CSR controllers

The rationale of showing this is that it's potentially critical
information to diagnose and find more CSR compatibility bugs in the
future and it will save a lot of headaches.

Given that clones come from a wide array of vendors (some are actually
Barrot, some are something else) and these numbers are what let us find
differences between actual and fake ones, it will be immensely helpful
to scour the Internet looking for this pattern and building an actual
database to find correlations and improve the checks.

Bluetooth: btusb: Fix CSR clones again by re-adding ERR_DATA_REPORTING quirk

A patch series by a Qualcomm engineer essentially removed my
quirk/workaround because they thought it was unnecessary.

It wasn't, and it broke everything again:

https://patchwork.kernel.org/project/netdevbpf/list/?series=661703&archive=both&state=*

He argues that the quirk is not necessary because the code should check
if the dongle says if it's supported or not. The problem is that for
these Chinese CSR clones they say that it would work:

the root cause: in unix_diag_get_exact(), the newly allocated skb does not

e1000e: Fix TX dispatch condition

e1000_xmit_frame is expected to stop the queue and dispatch frames to
hardware if there is not sufficient space for the next frame in the
buffer, but sometimes it failed to do so because the estimated maximum
size of frame was wrong. As the consequence, the later invocation of
e1000_xmit_frame failed with NETDEV_TX_BUSY, and the frame in the buffer
remained forever, resulting in a watchdog failure.

This change fixes the estimated size by making it match with the
condition for NETDEV_TX_BUSY. Apparently, the old estimation failed to
account for the following lines which determines the space requirement
for not causing NETDEV_TX_BUSY:
    ```
     /* reserve a descriptor for the offload context */
     if ((mss) || (skb->ip_summed == CHECKSUM_PARTIAL))
     count++;
     count++;

     count += DIV_ROUND_UP(len, adapter->tx_fifo_limit);
    ```

This issue was found when running http-stress02 test included in Linux
Test Project 20220930 on QEMU with the following commandline:

netfilter: conntrack: fix using __this_cpu_add in preemptible

Currently in nf_conntrack_hash_check_insert(), when it fails in

afs: Fix fileserver probe RTT handling

The fileserver probing code attempts to work out the best fileserver to
use for a volume by retrieving the RTT calculated by AF_RXRPC for the
probe call sent to each server and comparing them. Sometimes, however,
no RTT estimate is available and rxrpc_kernel_get_srtt() returns false,
leading good fileservers to be given an RTT of UINT_MAX and thus causing
the rotation algorithm to ignore them.

Fix afs_select_fileserver() to ignore rxrpc_kernel_get_srtt()'s return
value and just take the estimated RTT it provides - which will be capped
at 1 second.

net: mdiobus: fix unbalanced node reference count

I got the following report while doing device(mscc-miim) load test
with CONFIG_OF_UNITTEST and CONFIG_OF_DYNAMIC enabled:

  of_node_get()/of_node_put() unbalanced - destroy cset entry:
  attach overlay node /spi/soc@0/mdio@7107009c/ethernet-phy@0

If the 'fwnode' is not an acpi node, the refcount is get in
fwnode_mdiobus_phy_device_register(), but it has never been
put when the device is freed in the normal path. So call
fwnode_handle_put() in phy_device_release() to avoid leak.

If it's an acpi node, it has never been get, but it's put
in the error path, so call fwnode_handle_get() before
phy_device_register() to keep get/put operation balanced.

mptcp: don't orphan ssk in mptcp_close()

All of the subflows of a msk will be orphaned in mptcp_close(), which
means the subflows are in DEAD state. After then, DATA_FIN will be sent,
and the other side will response with a DATA_ACK for this DATA_FIN.

However, if the other side still has pending data, the data that received
on these subflows will not be passed to the msk, as they are DEAD and
subflow_data_ready() will not be called in tcp_data_ready(). Therefore,
these data can't be acked, and they will be retransmitted again and again,
until timeout.

Fix this by setting ssk->sk_socket and ssk->sk_wq to 'NULL', instead of
orphaning the subflows in __mptcp_close(), as Paolo suggested.

ipv4: Fix route deletion when nexthop info is not specified

When the kernel receives a route deletion request from user space it
tries to delete a route that matches the route attributes specified in
the request.

If only prefix information is specified in the request, the kernel
should delete the first matching FIB alias regardless of its associated
FIB info. However, an error is currently returned when the FIB info is
backed by a nexthop object:

# ip nexthop add id 1 via 192.0.2.2 dev dummy10
# ip route add 198.51.100.0/24 nhid 1
# ip route del 198.51.100.0/24
RTNETLINK answers: No such process

Fix by matching on such a FIB info when legacy nexthop attributes are
not specified in the request. An earlier check already covers the case
where a nexthop ID is specified in the request.

Add tests that cover these flows. Before the fix:

# ./fib_nexthops.sh -t ipv4_fcnal
...
TEST: Delete route when not specifying nexthop attributes           [FAIL]

Tests passed:  11
Tests failed:   1

After the fix:

# ./fib_nexthops.sh -t ipv4_fcnal
...
TEST: Delete route when not specifying nexthop attributes           [ OK ]

Tests passed:  12
Tests failed:   0

No regressions in other tests:

# ./fib_nexthops.sh
...
Tests passed: 228
Tests failed:   0

# ./fib_tests.sh

skb passed to network layer contains incorrect length.

In mux aggregation protocol, the datagram block received
from device contains block signature, packet & datagram
header. The right skb len to be calculated by subracting
datagram pad len from datagram length.

Whereas in mux lite protocol, the skb contains single
datagram so skb len is calculated by subtracting the
packet offset from datagram header.

Pull x86 fixes from Borislav Petkov:

- ioremap: mask out the bits which are not part of the physical address
   *after* the size computation is done to prevent any hypothetical
   ioremap failures

- Change the MSR save/restore functionality during suspend to rely on
   flags denoting that the related MSRs are actually supported vs
   reading them and assuming they are (an Atom one allows reading but
   not writing, thus breaking this scheme at resume time)

- prevent IV reuse in the AES-GCM communication scheme between SNP
   guests and the AMD secure processor

net: phy: fix null-ptr-deref while probe() failed

In phy_attach_direct(), after setting the 'dev->driver', probe() fails,
device_bind_driver() is not called, so the knode_driver->n_klist is not
set, then it causes null-ptr-deref in __device_release_driver() while
deleting device. Fix this by setting dev->driver to NULL in the error
path in phy_attach_direct().

"x86:

   - Fixes for Xen emulation. While nobody should be enabling it in the
     kernel (the only public users of the feature are the selftests),
     the bug effectively allows userspace to read arbitrary memory.

   - Correctness fixes for nested hypervisors that do not intercept INIT
     or SHUTDOWN on AMD; the subsequent CPU reset can cause a
     use-after-free when it disables virtualization extensions. While
     downgrading the panic to a WARN is quite easy, the full fix is a
     bit more laborious; there are also tests. This is the bulk of the
     pull request.

   - Fix race condition due to incorrect mmu_lock use around
     make_mmu_pages_available().

  Generic:

   - Obey changes to the kvm.halt_poll_ns module parameter in VMs not
     using KVM_CAP_HALT_POLL, restoring behavior from before the
