hw->aci.lock is already initialized in ixgbe_sw_init(), so
ixgbe_recovery_probe() doesn't need to initialize the lock. This
function is also not responsible for destroying the lock on failures.
Additionally, change the name of label in accordance with this change.

When ixgbe_recovery_probe() is invoked and this function fails,
allocated resources in advance are not completely freed, because
ixgbe_probe() returns ixgbe_recovery_probe() directly and
ixgbe_recovery_probe() only frees partial resources, resulting in memory
leaks including:
- adapter->io_addr
- adapter->jump_tables[0]
- adapter->mac_table
- adapter->rss_key
- adapter->af_xdp_zc_qps
The leaked MMIO region can be observed in /proc/vmallocinfo, and the
remaining leaks are reported by kmemleak.
Don't return ixgbe_recovery_probe() directly, and instead let
ixgbe_probe() to clean up resources on failures.

Add support for 10G-BX modules, i.e. 10GBit Ethernet over a single strand
Single-Mode fiber.
The initialization of a 10G-BX SFP+ is the same as for a 10G SX/LX module,
and is identified according to SFF-8472 table 5-3, footnote 3 by the
10G Ethernet Compliance Codes field being empty, the Nominal Bit
Rate being compatible with 12.5GBit, and the module being a fiber module
with a Single Mode fiber link length.

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Enable host bridge emulation for PCI_DOMAINS_GENERIC platforms (Dan
Williams)
- Switch vmd from custom domain number allocator to the common
allocator to prevent a potential race with new non-VMD buses (Dan
Williams)
- Enable Precision Time Measurement (PTM) only if device advertises
support for a relevant role, to prevent invalid PTM Requests that
cause ACS violations that are reported as AER Uncorrectable
Non-Fatal errors (Mika Westerberg)
Resource management:
- Prevent resource tree corruption when BAR resize fails (Ilpo
Järvinen)
- Restore BARs to the original size if a BAR resize fails (Ilpo
Järvinen)
- Remove BAR release from BAR resize attempts by the xe, i915, and
amdgpu drivers so the PCI core can restore BARs if the resize fails
(Ilpo Järvinen)
- Move Resizable BAR code to rebar.c (Ilpo Järvinen)
- Add pci_rebar_size_supported() and use it in i915 and xe (Ilpo
Järvinen)
- Add pci_rebar_get_max_size() and use it in xe and amdgpu (Ilpo
Järvinen)
Power management and error handling:
- For drivers using PCI legacy suspend, save config state at suspend
so that state (not any earlier state from enumeration, probe, or
error recovery) will be restored when resuming (Lukas Wunner)
- For devices with no driver or a driver that lacks power management,
save config state at hibernate so that state (not any earlier state
from enumeration, probe, or error recovery) will be restored when
resuming (Lukas Wunner)
- Save device config space on device addition, before driver binding,
so error recovery works more reliably (Lukas Wunner)
- Drop pci_save_state() from several drivers that no longer need it
since the PCI core always does it and pci_restore_state() no longer
invalidates the saved state (Lukas Wunner)
- Document use of pci_save_state() by drivers to capture the state
they want restored during error recovery (Lukas Wunner)
Power control:
- Add a struct pci_ops.assert_perst() function pointer to
assert/deassert PCIe PERST# and implement it for the qcom driver
(Krishna Chaitanya Chundru)
- Add DT binding and pwrctrl driver for the Toshiba TC9563 PCIe
switch, which must be held in reset after poweron so the pwrctrl
driver can configure the switch via I2C before bringing up the
links (Krishna Chaitanya Chundru)
Endpoint framework:
- Convert the endpoint doorbell test to use a threaded IRQ to fix a
'sleeping while atomic' issue (Bhanu Seshu Kumar Valluri)

to callers, which significantly simplifies pcie-apple (Marc
Zyngier)

caused an unrecoverable abort (Jim Quinlan)
Cadence PCIe controller driver:
- Add module support for Cadence platform host and endpoint
controller driver (Manikandan K Pillai)

Synopsys DesignWare PCIe controller driver:
- Clear L1 PM Substate Capability 'Supported' bits unless glue driver
says it's supported, which prevents users from enabling non-working
L1SS. Currently only qcom and tegra194 support L1SS (Bjorn Helgaas)
- Remove now-superfluous L1SS disable code from tegra194 (Bjorn

ixgbe_non_sfp_link_config() is called twice in ixgbe_open()
once to assign its return value to err and again in the
conditional check. This patch uses the stored err value
instead of calling the function a second time. This avoids
redundant work and ensures consistent error reporting.
Also fix a small typo in the ixgbe_remove() comment:
"The could be caused" -> "This could be caused".

In 2009, commit c82f63e411f1 ("PCI: check saved state before restore")
changed the behavior of pci_restore_state() such that it became necessary
to call pci_save_state() afterwards, lest recovery from subsequent PCI
errors fails.
The commit has just been reverted and so all the pci_save_state() after
pci_restore_state() calls that have accumulated in the tree are now
superfluous. Drop them.
Two drivers chose a different approach to achieve the same result:
drivers/scsi/ipr.c and drivers/net/ethernet/intel/e1000e/netdev.c set the
pci_dev's "state_saved" flag to true before calling pci_restore_state().
Drop this as well.

Convert the ixgbe driver to use the new .get_rx_ring_count ethtool
operation for handling ETHTOOL_GRXRINGS command. This simplifies the
code by extracting the ring count logic into a dedicated callback.
The new callback provides the same functionality in a more direct way,
following the ongoing ethtool API modernization.
This was compile-tested only.

dentry even when DEBUG_FS isn't enabled. In this case the dummy

The error path of ixgbe_recovery_probe() has two memory bugs.
For non-E610 adapters, the function jumps to clean_up_probe without
calling devlink_free(), leaking the devlink instance and its embedded
adapter structure.
For E610 adapters, devlink_free() is called at shutdown_aci, but
clean_up_probe then accesses adapter->state, sometimes triggering
use-after-free because adapter is embedded in devlink. This UAF is
similar to the one recently reported in ixgbe_remove(). (Link)
Fix both issues by moving devlink_free() after adapter->state access,
aligning with the cleanup order in ixgbe_probe().

Since ixgbe_adapter is embedded in devlink, calling devlink_free()
prematurely in the ixgbe_remove() path can lead to UAF. Move devlink_free()

Currently, during locating the CIVD section, the ixgbe driver loops
over the OROM area and at each iteration reads only OROM-datastruct-size
amount of data. This results in many small reads and is inefficient.
Optimize this by reading the entire OROM bank into memory once before
entering the loop. This significantly reduces the probing time.
Without this patch probing time may exceed over 25s, whereas with this
patch applied average time of probe is not greater than 5s.

Currently ixgbe driver checks periodically in its watchdog subtask if
there is anything to be transmitted (considering both Tx and XDP rings)
under state of carrier not being 'ok'. Such event is interpreted as Tx
hang and therefore results in interface reset.
This is currently problematic for ndo_xdp_xmit() as it is allowed to
produce descriptors when interface is going through reset or its carrier
is turned off.
Furthermore, XDP rings should not really be objects of Tx hang
detection. This mechanism is rather a matter of ndo_tx_timeout() being
called from dev_watchdog against Tx rings exposed to networking stack.
Taking into account issues described above, let us have a two fold fix -
do not respect XDP rings in local ixgbe watchdog and do not produce Tx
descriptors in ndo_xdp_xmit callback when there is some problem with
carrier currently. For now, keep the Tx hang checks in clean Tx irq
routine, but adjust it to not execute for XDP rings.

Resolve the budget negative overflow which leads to returning true in
ixgbe_xmit_zc even when the budget of descs are thoroughly consumed.
Before this patch, when the budget is decreased to zero and finishes
sending the last allowed desc in ixgbe_xmit_zc, it will always turn back
and enter into the while() statement to see if it should keep processing
packets, but in the meantime it unexpectedly decreases the value again to
'unsigned int (0--)', namely, UINT_MAX. Finally, the ixgbe_xmit_zc returns
true, showing 'we complete cleaning the budget'. That also means
'clean_complete = true' in ixgbe_poll.
The true theory behind this is if that budget number of descs are consumed,
it implies that we might have more descs to be done. So we should return
false in ixgbe_xmit_zc to tell napi poll to find another chance to start
polling to handle the rest of descs. On the contrary, returning true here
means job done and we know we finish all the possible descs this time and
we don't intend to start a new napi poll.
It is apparently against our expectations. Please also see how
ixgbe_clean_tx_irq() handles the problem: it uses do..while() statement
to make sure the budget can be decreased to zero at most and the negative
overflow never happens.
The patch adds 'likely' because we rarely would not hit the loop condition
since the standard budget is 256.

Users of the ixgbe driver report that after adding devlink support by
the commit a0285236ab93 ("ixgbe: add initial devlink support") their
configs got broken due to unwanted changes of interface names. It's
caused by automatic phys_port_name generation during devlink port
initialization flow.
To prevent from that set no_phys_port_name flag for ixgbe devlink ports.

Pull timer cleanups from Thomas Gleixner:
"A treewide cleanup of struct cycle_counter const annotations.
The initial idea of making them const was correct as they were
seperate instances. When they got embedded into larger data
structures, which are even modified by the callback this got moot. The
only reason why this went unnoticed is that the required
container_of() casts the const attribute forcefully away.
Stop pretending that it is const"

With large values of CONFIG_NR_CPUS, three Intel ethernet drivers fail to
compile like:
In function ‘i40e_free_q_vector’,
inlined from ‘i40e_vsi_alloc_q_vectors’ at drivers/net/ethernet/intel/i40e/i40e_main.c:12112:3:
571 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)
include/linux/rcupdate.h:1084:17: note: in expansion of macro ‘BUILD_BUG_ON’
1084 | BUILD_BUG_ON(offsetof(typeof(*(ptr)), rhf) >= 4096); \
drivers/net/ethernet/intel/i40e/i40e_main.c:5113:9: note: in expansion of macro ‘kfree_rcu’
5113 | kfree_rcu(q_vector, rcu);
| ^~~~~~~~~
The problem is that the 'rcu' member in 'q_vector' is too far from the start
of the structure. Move this member before the CPU mask instead, in all three
drivers.

Add Tx Hang detection due to an unhandled MDD Event.
Previously, a malicious VF could disable the entire port causing
TX to hang on the E610 card.
Those events that caused PF to freeze were not detected
as an MDD event and usually required a Tx Hang watchdog timer
to catch the suspension, and perform a physical function reset.
Implement flows in the affected PF driver in such a way to check
the cause of the hang, detect it as an MDD event and log an
entry of the malicious VF that caused the Hang.
The PF blocks the malicious VF, if it continues to be the source
of several MDD events.

When an event is detected it is logged and, for the time being, the
queue is immediately re-enabled. This is due to the lack of an API
to the hypervisor so it could deal with it as it chooses.

Add malicious driver detection to ixgbe driver. The supported devices
are E610 and X550.
Handling MDD events is enabled while VFs are created and turned off
when they are disabled. There is no runtime command to enable or
disable MDD independently.
MDD event is logged when malicious VF driver is detected. For example VF
can try to send incorrect Tx descriptor (TSO on, but length field not
correct). It can be reproduced by manipulating the driver, or using
driver with incorrect descriptor values.
Example log:
"Malicious event on VF 0 tx:128 rx:128"

New timestamping API was introduced in commit 66f7223039c0 ("net: add
NDOs for configuring hardware timestamping") from kernel v6.6.
It is time to convert the Intel ixgbe driver to the new API, so that
timestamping configuration can be removed from the ndo_eth_ioctl() path
completely.

In both the read callback for struct cyclecounter, and in struct
timecounter, struct cyclecounter is declared as a const pointer.
Unfortunatly, a number of users of this pointer treat it as a non-const
pointer as it is burried in a larger structure that is heavily modified by
the callback function when accessed. This lie had been hidden by the fact
that container_of() "casts away" a const attribute of a pointer without any
compiler warning happening at all.
Fix this all up by removing the const attribute in the needed places so
that everyone can see that the structure really isn't const, but can,
and is, modified by the users of it.
