77bdaf39f3 net: lan966x: Fix sleep in atomic context when updating MAC table
The function lan966x_mac_wait_for_completion is used to poll the status
of the MAC table using the function readx_poll_timeout. The problem with
this function is that is called also from atomic context. Therefore
update the function to use readx_poll_timeout_atomic.

b6ab149654 net: lan966x: Fix sleep in atomic context when injecting frames
On lan966x, when injecting a frame it was polling the register
QS_INJ_STATUS to see if it can continue with the injection of the frame.
The problem was that it was using readx_poll_timeout which could sleep
in atomic context.
This patch fixes this issue by using readx_poll_timeout_atomic.

The first patch updates the email address of Brian Silverman from his
former employer to his private address.

The next patch fixes DT bindings information for the tcan4x5x SPI CAN
driver.

The following patch targets the m_can driver and fixes the
introduction of FIFO bulk read support.

Another patch for the tcan4x5x driver, which fixes the max register
value for the regmap config.

The last patch for the flexcan driver marks the RX mailbox support for
the MCF5441X as support.

f04aefd465 can: flexcan: mark RX via mailboxes as supported on MCF5441X
Most flexcan IP cores support 2 RX modes:
- FIFO
- mailbox

The flexcan IP core on the MCF5441X cannot receive CAN RTR messages
via mailboxes. However the mailbox mode is more performant. The commit

| 1c45f5778a ("can: flexcan: add ethtool support to change rx-rtr setting during runtime")

added support to switch from FIFO to mailbox mode on these cores.

After testing the mailbox mode on the MCF5441X by Angelo Dureghello,
this patch marks it (without RTR capability) as supported. Further the
IP core overview table is updated, that RTR reception via mailboxes is
not supported.

db72589c49 can: m_can: m_can_fifo_{read,write}: don't read or write from/to FIFO if length is 0
In order to optimize FIFO access, especially on m_can cores attached
to slow busses like SPI, in patch

| e39381770e ("can: m_can: Disable IRQs on FIFO bus errors")

bulk read/write support has been added to the m_can_fifo_{read,write}
functions.

That change leads to the tcan driver to call
regmap_bulk_{read,write}() with a length of 0 (for CAN frames with 0
data length). regmap treats this as an error:

| tcan4x5x spi1.0 tcan4x5x0: FIFO write returned -22

This patch fixes the problem by not calling the
cdev->ops->{read,write)_fifo() in case of a 0 length read/write.

48079e7fdd ibmvnic: don't spin in tasklet
ibmvnic_tasklet() continuously spins waiting for responses to all
capability requests. It does this to avoid encountering an error
during initialization of the vnic. However if there is a bug in the
VIOS and we do not receive a response to one or more queries the
tasklet ends up spinning continuously leading to hard lock ups.

If we fail to receive a message from the VIOS it is reasonable to
timeout the login attempt rather than spin indefinitely in the tasklet.

151b6a5c06 ibmvnic: init ->running_cap_crqs early
We use ->running_cap_crqs to determine when the ibmvnic_tasklet() should
send out the next protocol message type. i.e when we get back responses
to all our QUERY_CAPABILITY CRQs we send out REQUEST_CAPABILITY crqs.
Similiary, when we get responses to all the REQUEST_CAPABILITY crqs, we
send out the QUERY_IP_OFFLOAD CRQ.

We currently increment ->running_cap_crqs as we send out each CRQ and
have the ibmvnic_tasklet() send out the next message type, when this
running_cap_crqs count drops to 0.

This assumes that all the CRQs of the current type were sent out before
the count drops to 0. However it is possible that we send out say 6 CRQs,
get preempted and receive all the 6 responses before we send out the
remaining CRQs. This can result in ->running_cap_crqs count dropping to
zero before all messages of the current type were sent and we end up
sending the next protocol message too early.

Instead initialize the ->running_cap_crqs upfront so the tasklet will
only send the next protocol message after all responses are received.

Use the cap_reqs local variable to also detect any discrepancy (either
now or in future) in the number of capability requests we actually send.

Currently only send_query_cap() is affected by this behavior (of sending
next message early) since it is called from the worker thread (during
reset) and from application thread (during ->ndo_open()) and they can be
preempted. send_request_cap() is only called from the tasklet  which
processes CRQ responses sequentially, is not be affected.  But to
maintain the existing symmtery with send_query_capability() we update
send_request_capability() also.

db9f0e8bf7 ibmvnic: Allow extra failures before disabling
If auto-priority-failover (APF) is enabled and there are at least two
backing devices of different priorities, some resets like fail-over,
change-param etc can cause at least two back to back failovers. (Failover
from high priority backing device to lower priority one and then back
to the higher priority one if that is still functional).

Depending on the timimg of the two failovers it is possible to trigger
a "hard" reset and for the hard reset to fail due to failovers. When this
occurs, the driver assumes that the network is unstable and disables the
VNIC for a 60-second "settling time". This in turn can cause the ethtool
command to fail with "No such device" while the vnic automatically recovers
a little while later.

Given that it's possible to have two back to back failures, allow for extra
failures before disabling the vnic for the settling time.

a8db854be2 octeontx2-pf: Forward error codes to VF
PF forwards its VF messages to AF and corresponding
replies from AF to VF. AF sets proper error code in the
replies after processing message requests. Currently PF
checks the error codes in replies and sends invalid
message to VF. This way VF lacks the information of
error code set by AF for its messages. This patch
changes that such that PF simply forwards AF replies
so that VF can handle error codes.

====================
Intel Wired LAN Driver Updates 2022-01-20

This series contains updates to i40e driver only.

Jedrzej increases delay for EMP reset and adds checks to ensure a VF
request to change queues can be met.

Sylwester moves the placement of the Flow Director queue as to not
fragment the queue pile which would cause later re-allocation issues.

Karen prevents VF reset being invoked while another is still occurring
to avoid reading invalid data.

Joe Damato fixes some statistics fields to match the values of the
fields they are based on.

This was caused by PF queue pile fragmentation due to
flow director VSI queue being placed right after main VSI.
Because of this main VSI was not able to resize its
queue allocation for XDP resulting in no queues allocated
for main VSI when XDP was turned on.

Fix this by always allocating last queue in PF queue pile
for a flow director VSI.

Before this patch VF interface vanished when
maximum queue number was exceeded. Driver tried
to add next queues even if there was not enough
space. PF sent incorrect number of queues to
the VF when there were not enough of them.

Add an additional condition introduced to check
available space in 'qp_pile' before proceeding.
This condition makes it impossible to add queues
if they number is greater than the number resulting
from available space.
Also add the search for free space in PF queue
pair piles.

d15c7e875d net: phy: broadcom: hook up soft_reset for BCM54616S
A problem was encountered with the Bel-Fuse 1GBT-SFP05 SFP module (which
is a 1 Gbps copper module operating in SGMII mode with an internal
BCM54616S PHY device) using the Xilinx AXI Ethernet MAC core, where the
module would work properly on the initial insertion or boot of the
device, but after the device was rebooted, the link would either only
come up at 100 Mbps speeds or go up and down erratically.

I found no meaningful changes in the PHY configuration registers between
the working and non-working boots, but the status registers seemed to
have a lot of error indications set on the SERDES side of the device on
the non-working boot. I suspect the problem is that whatever happens on
the SGMII link when the device is rebooted and the FPGA logic gets
reloaded ends up putting the module's onboard PHY into a bad state.

Since commit 6e2d85ec05 ("net: phy: Stop with excessive soft reset")
the genphy_soft_reset call is not made automatically by the PHY core
unless the callback is explicitly specified in the driver structure. For
most of these Broadcom devices, there is probably a hardware reset that
gets asserted to reset the PHY during boot, however for SFP modules
(where the BCM54616S is commonly found) no such reset line exists, so if
the board keeps the SFP cage powered up across a reboot, it will end up
with no reset occurring during reboots.

Hook up the genphy_soft_reset callback for BCM54616S to ensure that a
PHY reset is performed before the device is initialized. This appears to
fix the issue with erratic operation after a reboot with this SFP
module.

22c033989c include/linux/unaligned: replace kernel.h with the necessary inclusions
When kernel.h is used in the headers it adds a lot into dependency hell,
especially when there are circular dependencies are involved.

Replace kernel.h inclusion with the list of what is really being used.

The rest of the changes are induced by the above and may not be split.

f1131b9c23 net: phy: micrel: use kszphy_suspend()/kszphy_resume for irq aware devices
On a setup with KSZ9131 and MACB drivers it happens on suspend path, from
time to time, that the PHY interrupt arrives after PHY and MACB were
suspended (PHY via genphy_suspend(), MACB via macb_suspend()). In this
case the phy_read() at the beginning of kszphy_handle_interrupt() will
fail (as MACB driver is suspended at this time) leading to phy_error()
being called and a stack trace being displayed on console. To solve this
.suspend/.resume functions for all KSZ devices implementing
.handle_interrupt were replaced with kszphy_suspend()/kszphy_resume()
which disable/enable interrupt before/after calling
genphy_suspend()/genphy_resume().

The fix has been adapted for all KSZ devices which implements
.handle_interrupt but it has been tested only on KSZ9131.

1771afd474 net: cpsw: avoid alignment faults by taking NET_IP_ALIGN into account
Both versions of the CPSW driver declare a CPSW_HEADROOM_NA macro that
takes NET_IP_ALIGN into account, but fail to use it appropriately when
storing incoming packets in memory. This results in the IPv4 source and
destination addresses to appear misaligned in memory, which causes
aligment faults that need to be fixed up in software.

So let's switch from CPSW_HEADROOM to CPSW_HEADROOM_NA where needed.
This gets rid of any alignment faults on the RX path on a Beaglebone
White.

2d19c3fd80 net: axienet: increase default TX ring size to 128
With previous changes to make the driver handle the TX ring size more
correctly, the default TX ring size of 64 appears to significantly
bottleneck TX performance to around 600 Mbps on a 1 Gbps link on ZynqMP.
Increasing this to 128 seems to bring performance up to near line rate and
shouldn't cause excess bufferbloat (this driver doesn't yet support modern
byte-based queue management).

bb193e3db8 net: axienet: fix for TX busy handling
Network driver documentation indicates we should be avoiding returning
NETDEV_TX_BUSY from ndo_start_xmit in normal cases, since it requires
the packets to be requeued. Instead the queue should be stopped after
a packet is added to the TX ring when there may not be enough room for an
additional one. Also, when TX ring entries are completed, we should only
wake the queue if we know there is room for another full maximally
fragmented packet.

Print a warning if there is insufficient space at the start of start_xmit,
since this should no longer happen.

Combined with increasing the default TX ring size (in a subsequent
patch), this appears to recover the TX performance lost by previous changes
to actually manage the TX ring state properly.

In some cases where the Xilinx Ethernet core was used in 1000Base-X or
SGMII modes, which use the internal PCS/PMA PHY, and the MGT
transceiver clock source for the PCS was not running at the time the
FPGA logic was loaded, the core would come up in a state where the
PCS could not be found on the MDIO bus. To fix this, the Ethernet core
(including the PCS) should be reset after enabling the clocks, prior to
attempting to access the PCS using of_mdio_find_device.

b400c2f4f4 net: axienet: Wait for PhyRstCmplt after core reset
When resetting the device, wait for the PhyRstCmplt bit to be set
in the interrupt status register before continuing initialization, to
ensure that the core is actually ready. When using an external PHY, this
also ensures we do not start trying to access the PHY while it is still
in reset. The PHY reset is initiated by the core reset which is
triggered just above, but remains asserted for 5ms after the core is
reset according to the documentation.

The MgtRdy bit could also be waited for, but unfortunately when using
7-series devices, the bit does not appear to work as documented (it
seems to behave as some sort of link state indication and not just an
indication the transceiver is ready) so it can't really be relied on for
this purpose.

it into wireguard's noise.c locally, so that kernels that aren't using

hope this failure is temporary:

We previosuly assumed such modules were powered up in the correct mode,
continuing without further configuration as long as the required power
class was supported by the host.

Restore this behaviour, while preserving the intent of subsequent
patches to avoid the "Address Change Sequence not supported" warning
if we are not going to be accessing the DDM address.

Pull signal/exit/ptrace updates from Eric Biederman:
 "This set of changes deletes some dead code, makes a lot of cleanups
  which hopefully make the code easier to follow, and fixes bugs found
  along the way.

  The end-game which I have not yet reached yet is for fatal signals
  that generate coredumps to be short-circuit deliverable from
  complete_signal, for force_siginfo_to_task not to require changing
  userspace configured signal delivery state, and for the ptrace stops
  to always happen in locations where we can guarantee on all
  architectures that the all of the registers are saved and available on
  the stack.

  Removal of profile_task_ext, profile_munmap, and profile_handoff_task
  are the big successes for dead code removal this round.

  A bunch of small bug fixes are included, as most of the issues
  reported were small enough that they would not affect bisection so I
  simply added the fixes and did not fold the fixes into the changes
  they were fixing.

  There was a bug that broke coredumps piped to systemd-coredump. I
  dropped the change that caused that bug and replaced it entirely with
  something much more restrained. Unfortunately that required some
  rebasing.

  Some successes after this set of changes: There are few enough calls
  to do_exit to audit in a reasonable amount of time. The lifetime of
  struct kthread now matches the lifetime of struct task, and the
  pointer to struct kthread is no longer stored in set_child_tid. The
  flag SIGNAL_GROUP_COREDUMP is removed. The field group_exit_task is
  removed. Issues where task->exit_code was examined with
  signal->group_exit_code should been examined were fixed.

  There are several loosely related changes included because I am
  cleaning up and if I don't include them they will probably get lost.

  The original postings of these changes can be found at:

f542cdfa30 net: wwan: Fix MRU mismatch issue which may lead to data connection lost
In pci_generic.c there is a 'mru_default' in struct mhi_pci_dev_info.
This value shall be used for whole mhi if it's given a value for a specific product.
But in function mhi_net_rx_refill_work(), it's still using hard code value MHI_DEFAULT_MRU.
'mru_default' shall have higher priority than MHI_DEFAULT_MRU.
And after checking, this change could help fix a data connection lost issue.

 tc_get_qdisc+0x1cc/0x364
 rtnetlink_rcv_msg+0x124/0x340

The reason is that the driver isn't prepared to receive two tc filters
with the same cookie. It unconditionally creates a new struct
ocelot_vcap_filter for each tc filter, and it adds all filters with the
same identifier (cookie) to the ocelot_vcap_block.

The problem is here, in ocelot_vcap_filter_del():

	/* Gets index of the filter */
	index = ocelot_vcap_block_get_filter_index(block, filter);
	if (index < 0)
		return index;

	/* Delete filter */
	ocelot_vcap_block_remove_filter(ocelot, block, filter);

	/* Move up all the blocks over the deleted filter */
	for (i = index; i < block->count; i++) {
		struct ocelot_vcap_filter *tmp;

		tmp = ocelot_vcap_block_find_filter_by_index(block, i);
		vcap_entry_set(ocelot, i, tmp);
	}

what will happen is ocelot_vcap_block_get_filter_index() will return the
index (@index) of the first filter found with that cookie. This is _not_
the index of _this_ filter, but the other one with the same cookie,
because ocelot_vcap_filter_equal() gets fooled.

Then later, ocelot_vcap_block_remove_filter() is coded to remove all
filters that are ocelot_vcap_filter_equal() with the passed @filter.
So unexpectedly, both filters get deleted from the list.

Then ocelot_vcap_filter_del() will attempt to move all the other filters
up, again finding them by index (@i). The block count is 2, @index was 0,
so it will attempt to move up filter @i=0 and @i=1. It assigns tmp =
ocelot_vcap_block_find_filter_by_index(block, i), which is now a NULL
pointer because ocelot_vcap_block_remove_filter() has removed more than
one filter.

As far as I can see, this problem has been there since the introduction
of tc offload support, however I cannot test beyond the blamed commit
due to hardware availability. In any case, any fix cannot be backported
that far, due to lots of changes to the code base.

Therefore, let's go for the correct solution, which is to not call
ocelot_vcap_filter_add() and ocelot_vcap_filter_del(), unless the filter
is actually unique and not shared. For the shared filters, we should
just modify the ingress port mask and call ocelot_vcap_filter_replace(),
a function introduced by commit 95706be13b ("net: mscc: ocelot: create
a function that replaces an existing VCAP filter"). This way,
block->rules will only contain filters with unique cookies, by design.

33cb0ff30c net: mscc: ocelot: don't let phylink re-enable TX PAUSE on the NPI port
Since commit b39648079d ("net: mscc: ocelot: disable flow control on
NPI interface"), flow control should be disabled on the DSA CPU port
when used in NPI mode.

However, the commit blamed in the Fixes: tag below broke this, because
it allowed felix_phylink_mac_link_up() to overwrite SYS_PAUSE_CFG_PAUSE_ENA
for the DSA CPU port.

This issue became noticeable since the device tree update from commit
8fcea7be57 ("arm64: dts: ls1028a: mark internal links between Felix
and ENETC as capable of flow control").

The solution is to check whether this is the currently configured NPI
port from ocelot_phylink_mac_link_up(), and to not modify the statically
disabled PAUSE frame transmission if it is.

When the port is configured for lossless mode as opposed to tail drop
mode, but the link partner (DSA master) doesn't observe the transmitted
PAUSE frames, the switch termination throughput is much worse, as can be
seen below.

4e5bd03ae3 net: bonding: fix bond_xmit_broadcast return value error bug
In Linux bonding scenario, one packet is copied to several copies and sent
by all slave device of bond0 in mode 3(broadcast mode). The mode 3 xmit
function bond_xmit_broadcast() only ueses the last slave device's tx result
as the final result. In this case, if the last slave device is down, then
it always return NET_XMIT_DROP, even though the other slave devices xmit
success. It may cause the tx statistics error, and cause the application
(e.g. scp) consider the network is unreachable.

For example, use the following command to configure server A.

echo 3 > /sys/class/net/bond0/bonding/mode
ifconfig bond0 up
ifenslave bond0 eth0 eth1
ifconfig bond0 192.168.1.125
ifconfig eth0 up
ifconfig eth1 down
The slave device eth0 and eth1 are connected to server B(192.168.1.107).
Run the ping 192.168.1.107 -c 3 -i 0.2 command, the following information
is displayed.

PING 192.168.1.107 (192.168.1.107) 56(84) bytes of data.
64 bytes from 192.168.1.107: icmp_seq=1 ttl=64 time=0.077 ms
64 bytes from 192.168.1.107: icmp_seq=2 ttl=64 time=0.056 ms
64 bytes from 192.168.1.107: icmp_seq=3 ttl=64 time=0.051 ms

 192.168.1.107 ping statistics
0 packets transmitted, 3 received

Actually, the slave device eth0 of the bond successfully sends three
ICMP packets, but the result shows that 0 packets are transmitted.

Also if we use scp command to get remote files, the command end with the
following printings.

ssh_exchange_identification: read: Connection timed out

So this patch modifies the bond_xmit_broadcast to return NET_XMIT_SUCCESS
if one slave device in the bond sends packets successfully. If all slave
devices send packets fail, the discarded packets stats is increased. The
skb is released when there is no slave device in the bond or the last slave
device is down.

998c0bd2b3 net: ipa: prevent concurrent replenish
We have seen cases where an endpoint RX completion interrupt arrives
while replenishing for the endpoint is underway.  This causes another
instance of replenishing to begin as part of completing the receive
transaction.  If this occurs it can lead to transaction corruption.

Use a new flag to ensure only one replenish instance for an endpoint
executes at a time.
