When auxiliary_device_add() returns error and then calls
auxiliary_device_uninit(), callback function adev_release
calls kfree(madev). We shouldn't call kfree(madev) again
in the error handling path. Set 'madev' to NULL.

If we're not in a NAPI softirq context, we need to be careful
about how we call napi_consume_skb(), specifically we need to
call it with budget==0 to signal to it that we're not in a
safe context.
This was found while running some configuration stress testing
of traffic and a change queue config loop running, and this
curious note popped out:

I found that ionic_tx_clean() calls napi_consume_skb() which calls
napi_skb_cache_put(), but before that last call is the note
/* Zero budget indicate non-NAPI context called us, like netpoll */
and
DEBUG_NET_WARN_ON_ONCE(!in_softirq());
Those are pretty big hints that we're doing it wrong. We can pass a
context hint down through the calls to let ionic_tx_clean() know what
we're doing so it can call napi_consume_skb() correctly.

The switch global port interrupt mask, REG_SW_PORT_INT_MASK__4, is
defined as 0x001C in ksz9477_reg.h. The designers used 32-bit value in
anticipation for increase of port count in future product but currently
the maximum port count is 7 and the effective value is 0x7F in register
0x001F. Each port has its own interrupt mask and is defined as 0x#01F.
It uses only 4 bits for different interrupts.
The developer who implemented the current interrupt mechanism in the
switch driver noticed there are similarities between the mechanism to
mask port interrupts in global interrupt and individual interrupts in
each port and so used the same code to handle these interrupts. He
updated the code to use the new macro REG_SW_PORT_INT_MASK__1 which is
defined as 0x1F in ksz_common.h but he forgot to update the 32-bit write
to 8-bit as now the mask registers are 0x1F and 0x#01F.
In addition all KSZ switches other than the KSZ9897/KSZ9893 and LAN937X
families use only 8-bit access and so this common code will eventually
be changed to accommodate them.

Below is a summary of how the driver stores a reference to an skb during
transmit:
tx_buff[free_map[consumer_index]]->skb = new_skb;
free_map[consumer_index] = IBMVNIC_INVALID_MAP;
consumer_index ++;
Where variable data looks like this:
free_map == [4, IBMVNIC_INVALID_MAP, IBMVNIC_INVALID_MAP, 0, 3]
consumer_index^
tx_buff == [skb=null, skb=<ptr>, skb=<ptr>, skb=null, skb=null]
The driver has checks to ensure that free_map[consumer_index] pointed to
a valid index but there was no check to ensure that this index pointed
to an unused/null skb address. So, if, by some chance, our free_map and
tx_buff lists become out of sync then we were previously risking an
skb memory leak. This could then cause tcp congestion control to stop
sending packets, eventually leading to ETIMEDOUT.
Therefore, add a conditional to ensure that the skb address is null. If
not then warn the user (because this is still a bug that should be
patched) and free the old pointer to prevent memleak/tcp problems.

Avoid spurious link status logs that may ultimately be wrong; for example,
if the link is set to down with the cable plugged, then the cable is
unplugged and after this the link is set to up, the last new log that is
appearing is incorrectly telling that the link is up.
In order to avoid errors, show link status logs after link_reset
processing, and in order to avoid spurious as much as possible, only show
the link loss when some link status change is detected.

The errata DS80000754 recommends monitoring potential faults in
half-duplex mode for the KSZ9477 family.
half-duplex is not very common so I just added a critical message
when the fault conditions are detected. The switch can be expected
to be unable to communicate anymore in these states and a software
reset of the switch would be required which I did not implement.

There are 2 types of outstanding tx skb's:
Type 1: Packets that are sitting in the drivers ind_buff that are
waiting to be batch sent to the NIC. During a device reset, these are
freed with a call to ibmvnic_tx_scrq_clean_buffer()
Type 2: Packets that have been sent to the NIC and are awaiting a TX
completion IRQ. These are free'd during a reset with a call to
clean_tx_pools()
During any reset which requires us to free the tx irq, ensure that the
Type 2 skb references are freed. Since the irq is released, it is
impossible for the NIC to inform of any completions.
Furthermore, later in the reset process is a call to init_tx_pools()
which marks every entry in the tx pool as free (ie not outstanding).
So if the driver is to make a call to init_tx_pools(), it must first
be sure that the tx pool is empty of skb references.
This issue was discovered by observing the following in the logs during
EEH testing:
TX free map points to untracked skb (tso_pool 0 idx=4)
TX free map points to untracked skb (tso_pool 0 idx=5)
TX free map points to untracked skb (tso_pool 1 idx=36)

Ensure the inner IP header is part of the skb's linear data before
setting old_iph. Otherwise, on a non-linear skb, old_iph could point
outside of the packet data.
Unlike classical VXLAN, which always encapsulates Ethernet packets,
VXLAN-GPE can transport IP packets directly. In that case, we need to
look at skb->protocol to figure out if an Ethernet header is present.

The following two shared buffer operations make use of the Shared Buffer
Status Register (SBSR):
# devlink sb occupancy snapshot pci/0000:01:00.0
# devlink sb occupancy clearmax pci/0000:01:00.0
The register has two masks of 256 bits to denote on which ingress /
egress ports the register should operate on. Spectrum-4 has more than
256 ports, so the register was extended by cited commit with a new
'port_page' field.
However, when filling the register's payload, the driver specifies the
ports as absolute numbers and not relative to the first port of the port
page, resulting in memory corruptions [1].
Fix by specifying the ports relative to the first port of the port page.

Cited commit added support for a new reset flow ("all reset") which is
deeper than the existing reset flow ("software reset") and allows the
device's PCI firmware to be upgraded.
In the new flow the driver first tells the firmware that "all reset" is
required by issuing a new reset command (i.e., MRSR.command=6) and then
triggers the reset by having the PCI core issue a secondary bus reset
(SBR).
However, due to a race condition in the device's firmware the device is
not always able to recover from this reset, resulting in initialization
failures [1].
New firmware versions include a fix for the bug and advertise it using a
new capability bit in the Management Capabilities Mask (MCAM) register.
Avoid initialization failures by reading the new capability bit and
triggering the new reset flow only if the bit is set. If the bit is not
set, trigger a normal PCI hot reset by skipping the call to the
Management Reset and Shutdown Register (MRSR).
Normal PCI hot reset is weaker than "all reset", but it results in a
fully operational driver and allows users to flash a new firmware, if
they want to.

Currently, the ionic_run_xdp() doesn't handle multi-buffer packets
properly for XDP_TX and XDP_REDIRECT.
When a jumbo frame is received, the ionic_run_xdp() first makes xdp
frame with all necessary pages in the rx descriptor.
And if the action is either XDP_TX or XDP_REDIRECT, it should unmap
dma-mapping and reset page pointer to NULL for all pages, not only the
first page.
But it doesn't for SG pages. So, SG pages unexpectedly will be reused.
It eventually causes kernel panic.

The __ethtool_get_ts_info function returns directly if the device has a
get_ts_info() method. For bonding with an active slave, this works correctly
as we simply return the real device's timestamping information. However,
when there is no active slave, we only check the slave's TX software
timestamp information. We still need to set the phc index and RX timestamp
information manually. Otherwise, the result will be look like:
Time stamping parameters for bond0:
Capabilities:
software-transmit
PTP Hardware Clock: 0
Hardware Transmit Timestamp Modes: none
Hardware Receive Filter Modes: none
This issue does not affect VLAN or MACVLAN devices, as they only have one
downlink and can directly use the downlink's timestamping information.

When the mcp251xfd_start_xmit() function fails, the driver stops
processing messages, and the interrupt routine does not return,
running indefinitely even after killing the running application.
Error messages:
[ 441.298819] mcp251xfd spi2.0 can0: ERROR in mcp251xfd_start_xmit: -16
[ 441.306498] mcp251xfd spi2.0 can0: Transmit Event FIFO buffer not empty. (seq=0x000017c7, tef_tail=0x000017cf, tef_head=0x000017d0, tx_head=0x000017d3).
... and repeat forever.
The issue can be triggered when multiple devices share the same SPI
interface. And there is concurrent access to the bus.
The problem occurs because tx_ring->head increments even if
mcp251xfd_start_xmit() fails. Consequently, the driver skips one TX
package while still expecting a response in
mcp251xfd_handle_tefif_one().
Resolve the issue by starting a workqueue to write the tx obj
synchronously if err = -EBUSY. In case of another error, decrement
tx_ring->head, remove skb from the echo stack, and drop the message.

The very first flush in any port will flush all learned addresses in all
ports. This can be observed by unplugging the cable from one port while
additional ports are connected and dumping the fdb entries.
This problem is caused by the initially wrong value programmed to the
REG_SW_LUE_CTRL_1 register. Setting SW_FLUSH_STP_TABLE and
SW_FLUSH_MSTP_TABLE bits does not have an immediate effect. It is when
ksz9477_flush_dyn_mac_table() is called then the SW_FLUSH_STP_TABLE bit
takes effect and flushes all learned entries. After that call both bits
are reset and so the next port flush will not cause such problem again.

The XDP program can't correctly handle partially checksummed
packets, but works fine with fully checksummed packets. If the
device has already validated fully checksummed packets, then
the driver doesn't need to re-validate them, saving CPU resources.
Additionally, the driver does not drop all partially checksummed
packets when VIRTIO_NET_F_GUEST_CSUM is not negotiated. This is
not a bug, as the driver has always done this.

In virtio spec 0.95, VIRTIO_NET_F_GUEST_CSUM was designed to handle
partially checksummed packets, and the validation of fully checksummed
packets by the device is independent of VIRTIO_NET_F_GUEST_CSUM
negotiation. However, the specification erroneously stated:
"If VIRTIO_NET_F_GUEST_CSUM is not negotiated, the device MUST set flags
to zero and SHOULD supply a fully checksummed packet to the driver."
This statement is inaccurate because even without VIRTIO_NET_F_GUEST_CSUM
negotiation, the device can still set the VIRTIO_NET_HDR_F_DATA_VALID flag.
Essentially, the device can facilitate the validation of these packets'
checksums - a process known as RX checksum offloading - removing the need
for the driver to do so.
This scenario is currently not implemented in the driver and requires
correction. The necessary specification correction[1] has been made and
approved in the virtio TC vote.

After ecf848eb934b ("net: usb: ax88179_178a: fix link status when link is
set to down/up") to not reset from usbnet_open after the reset from
usbnet_probe at initialization stage to speed up this, some issues have
been reported.
It seems to happen that if the initialization is slower, and some time
passes between the probe operation and the open operation, the second reset
from open is necessary too to have the device working. The reason is that
if there is no activity with the phy, this is "disconnected".
In order to improve this, the solution is to detect when the phy is
"disconnected", and we can use the phy status register for this. So we will
only reset the device from reset operation in this situation, that is, only
if necessary.
The same bahavior is happening when the device is stopped (link set to
down) and later is restarted (link set to up), so if the phy keeps working
we only need to enable the mac again, but if enough time passes between the
device stop and restart, reset is necessary, and we can detect the
situation checking the phy status register too.

ice_aqc_opc_download_pkg (0x0C40) AQ sporadically returns error due
to FW issue. Fix this by retrying five times before moving to
Safe Mode. Sleep for 20 ms before retrying. This was tested with the
4.40 firmware.

Commit 24407a01e57c ("ice: Add 200G speed/phy type use") added support
for 200G PHY speeds, but did not include 200G link speed message
support. As a result the driver incorrectly reports Unknown for 200G
link speed.
Fix this by adding 200G support to ice_print_link_msg().

A bug in https://bugzilla.kernel.org/show_bug.cgi?id=218906 describes
that irdma would break and report hardware initialization failed after
suspend/resume with Intel E810 NIC (tested on 6.9.0-rc5).
The problem is caused due to the collision between the irq numbers
requested in irdma and the irq numbers requested in other drivers
after suspend/resume.
The irq numbers used by irdma are derived from ice's ice_pf->msix_entries
which stores mappings between MSI-X index and Linux interrupt number.
It's supposed to be cleaned up when suspend and rebuilt in resume but
it's not, causing irdma using the old irq numbers stored in the old
ice_pf->msix_entries to request_irq() when resume. And eventually
collide with other drivers.
This patch fixes this problem. On suspend, we call ice_deinit_rdma() to
clean up the ice_pf->msix_entries (and free the MSI-X vectors used by
irdma if we've dynamically allocated them). On resume, we call
ice_init_rdma() to rebuild the ice_pf->msix_entries (and allocate the
MSI-X vectors if we would like to dynamically allocate them).

__hwrm_send()
In case of token is released due to token->state == BNXT_HWRM_DEFERRED,
released token (set to NULL) is used in log messages. This issue is
expected to be prevented by HWRM_ERR_CODE_PF_UNAVAILABLE error code. But
this error code is returned by recent firmware. So some firmware may not
return it. This may lead to NULL pointer dereference.
Adjust this issue by adding token pointer check.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Firmware interface 1.10.2.118 has increased the size of
HWRM_PORT_PHY_QCFG response beyond the maximum size that can be
forwarded. When the VF's link state is not the default auto state,
the PF will need to forward the response back to the VF to indicate
the forced state. This regression may cause the VF to fail to
initialize.
Fix it by capping the HWRM_PORT_PHY_QCFG response to the maximum
96 bytes. The SPEEDS2_SUPPORTED flag needs to be cleared because the
new speeds2 fields are beyond the legacy structure. Also modify
bnxt_hwrm_fwd_resp() to print a warning if the message size exceeds 96
bytes to make this failure more obvious.

gve_rx_free_skb incorrectly leaves napi->skb referencing an skb after it
is freed with dev_kfree_skb_any(). This can result in a subsequent call
to napi_get_frags returning a dangling pointer.
Fix this by clearing napi->skb before the skb is freed.
