Intel platform will configure the SerDes through PMC API based on the
provided interface mode.
This patch adds several new functions below:-
- intel_tsn_lane_is_available(): This new function reads FIA lane
ownership registers and common lane registers through IPC commands
to know which lane the mGbE port is assigned to.
- intel_mac_finish(): To configure the SerDes based on the assigned
lane and latest interface mode, it sends IPC command to the PMC through
PMC driver/API. The PMC acts as a proxy for R/W on behalf of the driver.
- intel_set_reg_access(): Set the register access to the available TSN
interface.

The xpcs_switch_interface_mode function was introduced to handle
interface switching.
According to the XPCS datasheet, a soft reset is required to initiate
Clause 37 auto-negotiation when the XPCS switches interface modes.
When the interface mode switches from 2500BASE-X to SGMII,
re-initiating Clause 37 auto-negotiation is required for the SGMII
interface mode to function properly.

The phylink_expects_phy() function allows MAC drivers to check if they are
expecting a PHY to attach. The checking condition in phylink_expects_phy()
aims to achieve the same result as the checking condition in
phylink_attach_phy().
However, the checking condition in phylink_expects_phy() uses
pl->link_config.interface, while phylink_attach_phy() uses
pl->link_interface.
Initially, both pl->link_interface and pl->link_config.interface are set
to SGMII, and pl->cfg_link_an_mode is set to MLO_AN_INBAND.
When the interface switches from SGMII to 2500BASE-X,
pl->link_config.interface is updated by phylink_major_config().
At this point, pl->cfg_link_an_mode remains MLO_AN_INBAND, and
pl->link_config.interface is set to 2500BASE-X.
Subsequently, when the STMMAC interface is taken down
administratively and brought back up, it is blocked by
phylink_expects_phy().
Since phylink_expects_phy() and phylink_attach_phy() aim to achieve the
same result, phylink_expects_phy() should check pl->link_interface,
which never changes, instead of pl->link_config.interface, which is
updated by phylink_major_config().

ice_health_init() was introduced in the commit 2a82874a3b7b ("ice: add
Tx hang devlink health reporter"). The call to it should have been put
after ice_devlink_register(). It went unnoticed until next reporter by
Konrad, which receives events from FW. FW is reporting all events, also
from prior driver load, and thus it is not unlikely to have something
at the very beginning. And that results in a splat:
[ 24.455950] ? devlink_recover_notify.constprop.0+0x198/0x1b0

Ever since removing switchdev control VSI and using PF for port
representor Tx/Rx, switchdev slow-path has been working improperly after
failover in SR-IOV LAG. LAG assumes that the first uplink to be added to
the aggregate will own VFs and have switchdev configured. After
failing-over to the other uplink, representors are still configured to
Tx through the uplink they are set up on, which fails because that
uplink is now down.
On failover, update all PRs on primary uplink to use the currently
active uplink for Tx. Call netif_keep_dst(), as the secondary uplink
might not be in switchdev mode. Also make sure to call
ice_eswitch_set_target_vsi() if uplink is in LAG.
On the Rx path, representors are already working properly, because
default Tx from VFs is set to PF owning the eswitch. After failover the
same PF is receiving traffic from VFs, even though link is down.

Fix aRFS (accelerated Receive Flow Steering) structures memory leak by
adding a checker to verify if aRFS memory is already allocated while
configuring VSI. aRFS objects are allocated in two cases:
- as part of VSI initialization (at probe), and
- as part of reset handling
However, VSI reconfiguration executed during reset involves memory
allocation one more time, without prior releasing already allocated
resources. This led to the memory leak with the following signature:

After switchdev is enabled and disabled later, LLDP packets sending stops,
despite working perfectly fine before and during switchdev state.
To reproduce (creating/destroying VF is what triggers the reconfiguration):
devlink dev eswitch set pci/<address> mode switchdev
echo '2' > /sys/class/net/<ifname>/device/sriov_numvfs
echo '0' > /sys/class/net/<ifname>/device/sriov_numvfs
This happens because LLDP relies on the destination override functionality.
It needs to 1) set a flag in the descriptor, 2) set the VSI permission to
make it valid. The permissions are set when the PF VSI is first configured,
but switchdev then enables it for the uplink VSI (which is always the PF)
once more when configured and disables when deconfigured, which leads to
software-generated LLDP packets being blocked.
Do not modify the destination override permissions when configuring
switchdev, as the enabled state is the default configuration that is never
modified.

iwlwifi is the driver of all Intel wifi devices since 2008.
Since then, the hardware has changed a lot, but the firmware
API has changed even more. The need to keep one driver that
supports all those different APIs led us to introduce a new
architecture circa 2012 which allowed us to keep the same
interface to the hardware (DMAs, Tx queues, etc...) with a
new layer to implement the mid-layer between mac80211 and
the firmware. The first component is called the 'transport'
and the latter is called 'operation_mode' a.k.a op_mode.
In 2013 we took advantage of the new architecture to
introduce iwlmvm which allowed us to implement the, then,
new firmware API. This op_mode supports 7260 and up, those
devices supports support at least VHT.
Since then, wifi evolved and so did the firmware. It became
much bigger and took a lot of functionality from the driver.
It became increasingly hard to keep the same op_mode for the
newest devices and we experienced frequent regressions on
older devices. In order to avoid those regressions and keep
the code maintainable, we decided it was about time to start
a new op_mode.
iwlmld is a new op_mode that supports BE200 or newer if the
firmware being used is 97.ucode or newer. If the user has
an older devices or BE200 with .96.ucode, iwlmvm will be
loaded. Of course, this op_mode selection is seamless.
All the features supported in iwlmvm are supported in
iwlmld besides a few seldom used use cases: injection and
Hotspot 2.0. Those are under work.
A few points about the implementation:
* iwlmld doesn't have any mutexes, it relies on the
wiphy_lock
* iwlmld is more "resource oriented": stations, links and
interfaces are allocated and freed only after all the
relevant flows are completed.
* Firmware notifications' sizes are validated in a more
structured way.
We would love to see this new op_mode merged in 6.15. The
firmware for this new driver (.97.ucode) is not yet publicly
available but it'll be sent very soon.
People eager to get an early version of this firmware can

I've listed the people who directly contributed
code, but many others from various teams have

Syzbot caught an "KMSAN: uninit-value" warning [1], which is caused by the
ppp driver not initializing a 2-byte header when using socket filter.
The following code can generate a PPP filter BPF program:
'''
struct bpf_program fp;
pcap_t *handle;
handle = pcap_open_dead(DLT_PPP_PPPD, 65535);
pcap_compile(handle, &fp, "ip and outbound", 0, 0);
bpf_dump(&fp, 1);
'''
Its output is:
'''
(000) ldh [2]
(001) jeq #0x21 jt 2 jf 5
(002) ldb [0]
(003) jeq #0x1 jt 4 jf 5
(004) ret #65535
(005) ret #0
'''
Wen can find similar code at the following link:
https://github.com/ppp-project/ppp/blob/master/pppd/options.c#L1680
The maintainer of this code repository is also the original maintainer
of the ppp driver.
As you can see the BPF program skips 2 bytes of data and then reads the
'Protocol' field to determine if it's an IP packet. Then it read the first
byte of the first 2 bytes to determine the direction.
The issue is that only the first byte indicating direction is initialized
in current ppp driver code while the second byte is not initialized.
For normal BPF programs generated by libpcap, uninitialized data won't be
used, so it's not a problem. However, for carefully crafted BPF programs,
such as those generated by syzkaller [2], which start reading from offset
0, the uninitialized data will be used and caught by KMSAN.

This is the core patch for this whole patchset. Add support for
including the current task's name in netconsole's extra data output.
This adds a new append_taskname() function that writes the task name
(from current->comm) into the target's extradata buffer, similar to how
CPU numbers are handled.
The task name is included when the SYSDATA_TASKNAME field is set,
appearing in the format "taskname=<name>" in the output. This additional
context can help with debugging by showing which task generated each
console message.

Extract CPU number formatting logic from prepare_extradata() into a new
append_cpu_nr() function.
This refactoring improves code organization by isolating CPU number
formatting into its own function while reducing the complexity of
prepare_extradata().
The change prepares the codebase for the upcoming taskname feature by
establishing a consistent pattern for handling sysdata features.
The CPU number formatting logic itself remains unchanged; only its
location has moved to improve maintainability.

Convert the current state assignment to use explicit boolean conversion,
making the code more robust and easier to read. This change adds a
double-negation operator to ensure consistent boolean conversion as
suggested by Paolo[1].
This approach aligns with the existing pattern used in
sysdata_cpu_nr_enabled_show().

Rename the CPU_NR enum value to SYSDATA_CPU_NR to establish a consistent

upcoming additions to the sysdata feature set by clearly grouping
related features under the SYSDATA prefix.

The MAC hardware is on the BMC side, and the driver is on the host side.
When the driver is abnormal, the BMC cannot directly detect the
exception cause.
Therefore, this patch implements the BMC diagnosis feature.
When users query driver diagnosis information on the BMC, the driver
detects the query request in the scheduled task and reports
driver statistics and link status to the BMC through the bar space.
The BMC collects logs to analyze exception causes.
Currently, the scheduled task is executed every 30 seconds
To quickly respond to user query requests,
this patch changes the scheduled task to once every second.

If the rate changed frequently, the PHY link ok,
but the MAC link maybe fails.
As a result, the network port is unavailable.
According to the documents of the chip,
core_reset needs to do to fix the fault.
In hw_adjus_link(), the core_reset is added to try to
ensure that MAC link status is normal.
In addition, MAC link failure detection is added.
If the MAC link fails after core_reset, driver invokes
the phy_stop() and phy_start() to re-link.
Due to phydev->lock, re-link cannot be triggered
in adjust_link(). Therefore, this operation
is invoked in a scheduled task.
