A recent commit restored the original (and still documented) semantics
for the HCI_QUIRK_USE_BDADDR_PROPERTY quirk so that the device address
is considered invalid unless an address is provided by firmware.
This specifically means that this flag must only be set for devices with
invalid addresses, but the Broadcom BCM4377 driver has so far been
setting this flag unconditionally.
Fortunately the driver already checks for invalid addresses during setup
and sets the HCI_QUIRK_INVALID_BDADDR flag, which can simply be replaced
with HCI_QUIRK_USE_BDADDR_PROPERTY to indicate that the default address
is invalid but can be overridden by firmware (long term, this should
probably just always be allowed).

Currently when suspending driver and stopping workqueue it is checked whether
workqueue is not NULL and if so, it is destroyed.
Function destroy_workqueue() does drain queue and does clear variable, but
it does not set workqueue variable to NULL. This can cause kernel/module
panic if code attempts to clear workqueue that was not initialized.
This scenario is possible when resuming suspended driver in stmmac_resume(),
because there is no handling for failed stmmac_hw_setup(),
which can fail and return if DMA engine has failed to initialize,
and workqueue is initialized after DMA engine.
Should DMA engine fail to initialize, resume will proceed normally,
but interface won't work and TX queue will eventually timeout,
causing 'Reset adapter' error.
This then does destroy workqueue during reset process.
And since workqueue is initialized after DMA engine and can be skipped,
it will cause kernel/module panic.
To secure against this possible crash, set workqueue variable to NULL when
destroying workqueue.
Log/backtrace from crash goes as follows:

The MII code does not check the return value of mdio_read (among
others), and therefore no error code should be sent. A previous fix to
the use of an uninitialized variable propagates negative error codes,
that might lead to wrong operations by the MII library.
An example of such issues is the use of mii_nway_restart by the dm9601
driver. The mii_nway_restart function does not check the value returned
by mdio_read, which in this case might be a negative number which could
contain the exact bit the function checks (BMCR_ANENABLE = 0x1000).
Return zero in case of error, as it is common practice in users of
mdio_read to avoid wrong uses of the return value.

Since we now have potential cases of NULL cmd_regs and info_regs
during a reset recovery, and left NULL if a reset recovery has
failed, we need to check that they exist before we use them.
Most of the cases were covered in the original patch where we
verify before doing the ioreadb() for health or cmd status.
However, we need to protect a few uses of io mem that could
be hit in error recovery or asynchronous threads calls as well
(e.g. ethtool or devlink handlers).

AER recovery handler can trigger a PCI Reset after tearing
down the device setup in the error detection handler. The PCI
Reset handler will also attempt to tear down the device setup,
and this second tear down needs to know that it doesn't need
to call pci_release_regions() a second time. We can clear
num_bars on tear down and use that to decide later if we need
to clear the resources. This prevents a harmless but disturbing

Same as LAN7800, LAN7850 can be used without EEPROM. If EEPROM is not
present or not flashed, LAN7850 will fail to sync the speed detected by the PHY
with the MAC. In case link speed is 100Mbit, it will accidentally work,
otherwise no data can be transferred.
Better way would be to implement link_up callback, or set auto speed
configuration unconditionally. But this changes would be more intrusive.
So, for now, set it only if no EEPROM is found.

veth sets NETIF_F_GRO automatically when XDP is enabled,
because both features use the same NAPI machinery.
The logic to clear NETIF_F_GRO sits in veth_disable_xdp() which
is called both on ndo_stop and when XDP is turned off.
To avoid the flag from being cleared when the device is brought
down, the clearing is skipped when IFF_UP is not set.
Bringing the device down should indeed not modify its features.
Unfortunately, this means that clearing is also skipped when
XDP is disabled _while_ the device is down. And there's nothing
on the open path to bring the device features back into sync.
IOW if user enables XDP, disables it and then brings the device
up we'll end up with a stray GRO flag set but no NAPI instances.
We don't depend on the GRO flag on the datapath, so the datapath
won't crash. We will crash (or hang), however, next time features
are sync'ed (either by user via ethtool or peer changing its config).
The GRO flag will go away, and veth will try to disable the NAPIs.
But the open path never created them since XDP was off, the GRO flag
was a stray. If NAPI was initialized before we'll hang in napi_disable().
If it never was we'll crash trying to stop uninitialized hrtimer.
Move the GRO flag updates to the XDP enable / disable paths,
instead of mixing them with the ndo_open / ndo_close paths.

tree
Since commit 5d93cfcf7360 ("net: dpaa: Convert to phylink"), we support
the "10gbase-r" phy-mode through a driver-based conversion of "xgmii",
but we still don't actually support it when the device tree specifies
"10gbase-r" proper.
This is because boards such as LS1046A-RDB do not define pcs-handle-names
(for whatever reason) in the ethernet@f0000 device tree node, and the
code enters through this code path:
err = of_property_match_string(mac_node, "pcs-handle-names", "xfi");
// code takes neither branch and falls through
if (err >= 0) {
(...)
} else if (err != -EINVAL && err != -ENODATA) {
goto _return_fm_mac_free;
}
(...)
/* For compatibility, if pcs-handle-names is missing, we assume this
* phy is the first one in pcsphy-handle
*/
err = of_property_match_string(mac_node, "pcs-handle-names", "sgmii");
if (err == -EINVAL || err == -ENODATA)
pcs = memac_pcs_create(mac_node, 0); // code takes this branch
else if (err < 0)
goto _return_fm_mac_free;
else
pcs = memac_pcs_create(mac_node, err);
// A default PCS is created and saved in "pcs"
// This determination fails and mistakenly saves the default PCS
// memac->sgmii_pcs instead of memac->xfi_pcs, because at this
// stage, mac_dev->phy_if == PHY_INTERFACE_MODE_10GBASER.
if (err && mac_dev->phy_if == PHY_INTERFACE_MODE_XGMII)
memac->xfi_pcs = pcs;
else
memac->sgmii_pcs = pcs;
In other words, in the absence of pcs-handle-names, the default
xfi_pcs assignment logic only works when in the device tree we have
PHY_INTERFACE_MODE_XGMII.
By reversing the order between the fallback xfi_pcs assignment and the
"xgmii" overwrite with "10gbase-r", we are able to support both values
in the device tree, with identical behavior.
Currently, it is impossible to make the s/xgmii/10gbase-r/ device tree
conversion, because it would break forward compatibility (new device
tree with old kernel). The only way to modify existing device trees to
phy-interface-mode = "10gbase-r" is to fix stable kernels to accept this
value and handle it properly.
One reason why the conversion is desirable is because with pre-phylink
kernels, the Aquantia PHY driver used to warn about the improper use
of PHY_INTERFACE_MODE_XGMII [1]. It is best to have a single (latest)
device tree that works with all supported stable kernel versions.
Note that the blamed commit does not constitute a regression per se.
Older stable kernels like 6.1 still do not work with "10gbase-r", but
for a different reason. That is a battle for another time.

Commit bb726b753f75 ("net: phy: realtek: add support for
RTL8211F(D)(I)-VD-CG") extended support of the driver from the existing
support for RTL8211F(D)(I)-CG PHY to the newer RTL8211F(D)(I)-VD-CG PHY.
While that commit indicated that the RTL8211F_PHYCR2 register is not
supported by the "VD-CG" PHY model and therefore updated the corresponding
section in rtl8211f_config_init() to be invoked conditionally, the call to
"genphy_soft_reset()" was left as-is, when it should have also been invoked
conditionally. This is because the call to "genphy_soft_reset()" was first
introduced by the commit 0a4355c2b7f8 ("net: phy: realtek: add dt property
to disable CLKOUT clock") since the RTL8211F guide indicates that a PHY
reset should be issued after setting bits in the PHYCR2 register.
As the PHYCR2 register is not applicable to the "VD-CG" PHY model, fix the
rtl8211f_config_init() function by invoking "genphy_soft_reset()"
conditionally based on the presence of the "PHYCR2" register.

Both registers used when doing manual injection or fdma injection are
shared between all the net devices of the switch. It was noticed that
when having two process which each of them trying to inject frames on
different ethernet ports, that the HW started to behave strange, by
sending out more frames then expected. When doing fdma injection it is
required to set the frame in the DCB and then make sure that the next
pointer of the last DCB is invalid. But because there is no locks for
this, then easily this pointer between the DCB can be broken and then it
would create a loop of DCBs. And that means that the HW will
continuously transmit these frames in a loop. Until the SW will break
this loop.
Therefore to fix this issue, add a spin lock for when accessing the
registers for manual or fdma injection.

Fix EST offset for dwmac 5.10.
Currently configuring Qbv doesn't work as expected. The schedule is
configured, but never confirmed:
|[ 128.250219] imx-dwmac 428a0000.ethernet eth1: configured EST
The reason seems to be the refactoring of the EST code which set the wrong
EST offset for the dwmac 5.10. After fixing this it works as before:
|[ 106.359577] imx-dwmac 428a0000.ethernet eth1: configured EST

Because of that, we were looking at the size of the VO fifo size to

In newer hardware, IPA supports more than 32 endpoints. Some
registers--such as IPA interrupt registers--represent endpoints
as bits in a 4-byte register, and such registers are repeated as
needed to represent endpoints beyond the first 32.
In ipa_interrupt_suspend_clear_all(), we clear all pending IPA
suspend interrupts by reading all status register(s) and writing
corresponding registers to clear interrupt conditions.
Unfortunately the number of registers to read/write is calculated
incorrectly, and as a result we access *many* more registers than
intended. This bug occurs only when the IPA hardware signals a
SUSPEND interrupt, which happens when a packet is received for an
endpoint (or its underlying GSI channel) that is suspended. This
situation is difficult to reproduce, but possible.
Fix this by correctly computing the number of interrupt registers to
read and write. This is the only place in the code where registers
that map endpoints or channels this way perform this calculation.

AF reserves MCAM entries for each PF, VF present in the
system and populates the entry with DMAC and action with
default RSS so that basic packet I/O works. Since PF/VF is
not aware of the RSS action installed by AF, AF only fixup
the actions of the rules installed by PF/VF with corresponding
default RSS action. This worked well for rules installed by
PF/VF for features like RX VLAN offload and DMAC filters but
rules involving action like drop/forward to queue are also
getting modified by AF. Hence fix it by setting the default
RSS action only if requested by PF/VF.

Commit 91fdbce7e8d6 ("ice: Add support in the driver for associating
queue with napi") invoked the netif_queue_set_napi() call. This
kernel function requires to be called with rtnl_lock taken,
otherwise ASSERT_RTNL() warning will be triggered. ice_vsi_rebuild()
initiating this call is under rtnl_lock when the rebuild is in
response to configuration changes from external interfaces (such as
tc, ethtool etc. which holds the lock). But, the VSI rebuild
generated from service tasks and resets (PFR/CORER/GLOBR) is not
under rtnl lock protection. Handle these cases as well to hold lock
before the kernel call (by setting the 'locked' boolean to false).
netif_queue_set_napi() is also used to clear previously set napi
in the q_vector unroll flow. Handle this for locked/lockless execution
paths.

Guenter Roeck reports that commit a64056bb5a32 ("drm/tests/drm_buddy:
add alloc_contiguous test") causes build failures on 32-bit targets:
"This patch breaks the build on all 32-bit systems since it introduces
an unhandled direct 64-bit divide operation.
ERROR: modpost: "__umoddi3" [drivers/gpu/drm/tests/drm_buddy_test.ko] undefined!
ERROR: modpost: "__moddi3" [drivers/gpu/drm/tests/drm_buddy_test.ko] undefined!"
and the uses of 'u64' are all entirely pointless. Yes, the arguments to
drm_buddy_init() and drm_buddy_alloc_blocks() are in fact of type 'u64',
but none of the values here are remotely relevant, and the compiler will
happily just do the type expansion.
Of course, in a perfect world the compiler would also have just noticed
that all the values in question are tiny, and range analysis would have
shown that doing a 64-bit divide is pointless, but that is admittedly
expecting a fair amount of the compiler.
IOW, we shouldn't write code that the compiler then has to notice is
unnecessarily complicated just to avoid extra work. We do have fairly
high expectations of compilers, but kernel code should be reasonable to
begin with.
It turns out that there are also other issues with this code: the KUnit
assertion messages have incorrect types in the format strings, but
that's a widely spread issue caused by the KUnit infrastructure not
having enabled format string verification. We'll get that sorted out
separately.

Do not allow to acquire data or alter configuration of dpll and pins
through firmware if PF reset is in progress, this would cause confusing
netlink extack errors as the firmware cannot respond or process the
request properly during the reset time.
Return (-EBUSY) and extack error for the user who tries access/modify
the config of dpll/pin through firmware during the reset time.
The PF reset and kernel access to dpll data are both asynchronous. It is
not possible to guard all the possible reset paths with any determinictic
approach. I.e., it is possible that reset starts after reset check is
performed (or if the reset would be checked after mutex is locked), but at
the same time it is not possible to wait for dpll mutex unlock in the
reset flow.
This is best effort solution to at least give a clue to the user
what is happening in most of the cases, knowing that there are possible
race conditions where the user could see a different error received
from firmware due to reset unexpectedly starting.
Test by looping execution of below steps until netlink error appears:

$ echo 1 > /sys/class/net/<ice PF>/device/reset

Fix the connection state between source DPLL and output pin, updating the
attribute 'state' of 'parent_device'. Previously, the connection state
was broken, and didn't reflect the correct state.
When 'state_on_dpll_set' is called with the value
'DPLL_PIN_STATE_CONNECTED' (1), the output pin will switch to the given
DPLL, and the state of the given DPLL will be set to connected.
E.g.:
--do pin-set --json '{"id":2, "parent-device":{"parent-id":1,
"state": 1 }}'
This command will connect DPLL device with id 1 to output pin with id 2.
When 'state_on_dpll_set' is called with the value
'DPLL_PIN_STATE_DISCONNECTED' (2) and the given DPLL is currently
connected, then the output pin will be disabled.
E.g:
--do pin-set --json '{"id":2, "parent-device":{"parent-id":1,
"state": 2 }}'
This command will disable output pin with id 2 if DPLL device with ID 1 is

Pull driver core fixes from Greg KH:
"Here are some driver core fixes, a kobject fix, and a documentation
update for 6.8-rc5. In detail these changes are:
- devlink fixes for reported issues with 6.8-rc1
- topology scheduling regression fix that has been reported by many
- kobject loosening of checks change in -rc1 is now reverted as some
codepaths seemed to need the checks
- documentation update for the CVE process. Has been reviewed by
many, the last minute change to the document was to bring the .rst
format back into the the new style rules, the contents did not
change.
All of these, except for the documentation update, have been in
linux-next for over a week. The documentation update has been reviewed
for weeks by a group of developers, and in public for a week and the
wording has stabilized for now. If future changes are needed, we can
do so before 6.8-final is out (or anytime after that)"
