ice/ptp: fix crosstimestamp reporting
Set use_nsecs=true as timestamp is reported in ns. Lack of this result
in smaller timestamp error window which cause error during phc2sys

phc2sys[1768.256]: ioctl PTP_SYS_OFFSET_PRECISE: Invalid argument
This problem was introduced in the cited commit which omitted setting
use_nsecs to true when converting the ice driver to use
convert_base_to_cs().

ice: change SMA pins to SDP in PTP API
This change aligns E810 PTP pin control to all other products. Currently, SMA/U.FL port expanders are controlled together with SDP pins connected to 1588 clock. To align this, separate this control by exposing only SDP20..23 pins in PTP API on adapters with DPLL. Clear error for all E810 on absent NVM pin section or other errors to allow proper initialization on SMA E810 with NVM section. Use ARRAY_SIZE for pin array instead of internal definition.

net: ptp: introduce .supported_perout_flags to ptp_clock_info
The PTP_PEROUT_REQUEST2 ioctl has gained support for flags specifying specific output behavior including PTP_PEROUT_ONE_SHOT, PTP_PEROUT_DUTY_CYCLE, PTP_PEROUT_PHASE. Driver authors are notorious for not checking the flags of the request. This results in misinterpreting the request, generating an output signal that does not match the requested value. It is anticipated that even more flags will be added in the future, resulting in even more broken requests. Expecting these issues to be caught during review or playing whack-a-mole after the fact is not a great solution. Instead, introduce the supported_perout_flags field in the ptp_clock_info structure. Update the core character device logic to explicitly reject any request which has a flag not on this list. This ensures that drivers must 'opt in' to the flags they support. Drivers which don't set the .supported_perout_flags field will not need to check that unsupported flags aren't passed, as the core takes care of this. Update the drivers which do support flags to set this new field. Note the following driver files set n_per_out to a non-zero value but did not check the flags at all: • drivers/ptp/ptp_clockmatrix.c • drivers/ptp/ptp_idt82p33.c • drivers/ptp/ptp_fc3.c • drivers/net/ethernet/ti/am65-cpts.c • drivers/net/ethernet/aquantia/atlantic/aq_ptp.c • drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c • drivers/net/dsa/sja1105/sja1105_ptp.c • drivers/net/ethernet/freescale/dpaa2/dpaa2-ptp.c • drivers/net/ethernet/mscc/ocelot_vsc7514.c • drivers/net/ethernet/intel/i40e/i40e_ptp.c Reviewed-by: Vadim Fedorenko <vadim.fedorenko@linux.dev> Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Reviewed-by: Kory Maincent <kory.maincent@bootlin.com> Link: https://patch.msgid.link/20250414-jk-supported-perout-flags-v2-2-f6b17d15475c@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

net: ptp: introduce .supported_extts_flags to ptp_clock_info
The PTP_EXTTS_REQUEST(2) ioctl has a flags field which specifies how the external timestamp request should behave. This includes which edge of the signal to timestamp, as well as a specialized "offset" mode. It is expected that more flags will be added in the future. Driver authors routinely do not check the flags, often accepting requests with flags which they do not support. Even drivers which do check flags may not be future-proofed to reject flags not yet defined. Thus, any future flag additions often require manually updating drivers to reject these flags. This approach of hoping we catch flag checks during review, or playing whack-a-mole after the fact is the wrong approach. Introduce the "supported_extts_flags" field to the ptp_clock_info structure. This field defines the set of flags the device actually supports. Update the core character device logic to check this field and reject unsupported requests. Getting this right is somewhat tricky. First, to avoid unnecessary repetition and make basic functionality work when .supported_extts_flags is 0, the core always accepts the PTP_ENABLE_FEATURE flag. This flag is used to set the 'on' parameter to the .enable function and is thus always 'supported' by all drivers. For backwards compatibility, the PTP_RISING_EDGE and PTP_FALLING_EDGE flags are merely "hints" when using the old PTP_EXTTS_REQUEST ioctl, and are not expected to be enforced. If the user issues PTP_EXTTS_REQUEST2, the PTP_STRICT_FLAGS flag is added which is supposed to inform the driver to strictly validate the flags and reject unsupported requests. To handle this, first check if the driver reports PTP_STRICT_FLAGS support. If it does not, then always allow the PTP_RISING_EDGE and PTP_FALLING_EDGE flags. This keeps backwards compatibility with the original PTP_EXTTS_REQUEST ioctl where these flags are not guaranteed to be honored. This way, drivers which do not set the supported_extts_flags will continue to accept requests for the original PTP_EXTTS_REQUEST ioctl. The core will automatically reject requests with new flags, and correctly reject requests with PTP_STRICT_FLAGS, where the driver is supposed to strictly validate the flags. Update the various drivers, refactoring their validation logic into the .supported_extts_flags field. For consistency and readability, PTP_ENABLE_FEATURE is not set in the supported flags list, and PTP_EXTTS_EDGES is expanded to PTP_RISING_EDGE | PTP_FALLING_EDGE in all cases. Note the following driver files set n_ext_ts to a non-zero value but did not check flags at all: • drivers/net/ethernet/freescale/dpaa2/dpaa2-ptp.c • drivers/net/ethernet/freescale/enetc/enetc_ptp.c • drivers/net/ethernet/intel/i40e/i40e_ptp.c • drivers/net/ethernet/marvell/octeontx2/nic/otx2_ptp.c • drivers/net/ethernet/renesas/ravb_ptp.c • drivers/net/ethernet/renesas/rtsn.c • drivers/net/ethernet/renesas/rtsn.h • drivers/net/ethernet/ti/am65-cpts.c • drivers/net/ethernet/ti/cpts.h • drivers/net/ethernet/ti/icssg/icss_iep.c • drivers/net/ethernet/xscale/ptp_ixp46x.c • drivers/net/phy/bcm-phy-ptp.c • drivers/ptp/ptp_ocp.c • drivers/ptp/ptp_pch.c • drivers/ptp/ptp_qoriq.c These drivers behavior does change slightly: they will now reject the PTP_EXTTS_REQUEST2 ioctl, because they do not strictly validate their flags. This also makes them no longer incorrectly accept PTP_EXT_OFFSET. Also note that the renesas ravb driver does not support PTP_STRICT_FLAGS. We could leave the .supported_extts_flags as 0, but I added the PTP_RISING_EDGE | PTP_FALLING_EDGE since the driver previously manually validated these flags. This is equivalent to 0 because the core will allow these flags regardless unless PTP_STRICT_FLAGS is also set.

ice: enable timesync operation on 2xNAC E825 devices
According to the E825C specification, SBQ address for ports on a single complex is device 2 for PHY 0 and device 13 for PHY1. For accessing ports on a dual complex E825C (so called 2xNAC mode), the driver should use destination device 2 (referred as phy_0) for the current complex PHY and device 13 (referred as phy_0_peer) for peer complex PHY. Differentiate SBQ destination device by checking if current PF port number is on the same PHY as target port number. Adjust 'ice_get_lane_number' function to provide unique port number for ports from PHY1 in 'dual' mode config (by adding fixed offset for PHY1 ports). Cache this value in ice_hw struct. Introduce ice_get_primary_hw wrapper to get access to timesync register not available from second NAC.

ice: ensure periodic output start time is in the future
On E800 series hardware, if the start time for a periodic output signal is programmed into GLTSYN_TGT_H and GLTSYN_TGT_L registers, the hardware logic locks up and the periodic output signal never starts. Any future attempt to reprogram the clock function is futile as the hardware will not reset until a power on. The ice_ptp_cfg_perout function has logic to prevent this, as it checks if the requested start time is in the past. If so, a new start time is calculated by rounding up. Since commit |

ice: support Rx timestamp on flex descriptor
To support Rx timestamp offload, VIRTCHNL_OP_1588_PTP_CAPS is sent by the VF to request PTP capability and responded by the PF what capability is enabled for that VF. Hardware captures timestamps which contain only 32 bits of nominal nanoseconds, as opposed to the 64bit timestamps that the stack expects. To convert 32b to 64b, we need a current PHC time. VIRTCHNL_OP_1588_PTP_GET_TIME is sent by the VF and responded by the PF with the current PHC time.

ice: Add unified ice_capture_crosststamp
Devices supported by ice driver use essentially the same logic for performing a crosstimestamp. The only difference is that E830 hardware has different offsets. Instead of having multiple implementations, combine them into a single ice_capture_crosststamp() function. To support both hardware types, the ice_capture_crosststamp function must be able to determine the appropriate registers to access. To handle this, pass a custom context structure instead of the PF pointer. This structure, ice_crosststamp_ctx, contains a pointer to the PF, and a pointer to the device configuration structure. This new structure also will make it easier to implement historic snapshot support in a future commit. The device configuration structure is a static const data which defines the offsets and flags for the various registers. This includes the lock register, the cross timestamp control register, the upper and lower ART system time capture registers, and the upper and lower device time capture registers for each timer index. Use the configuration structure to access all of the registers in ice_capture_crosststamp(). Ensure that we don't over-run the device time array by checking that the timer index is 0 or 1. Previously this was simply assumed, and it would cause the device to read an incorrect and likely garbage register. It does feel like there should be a kernel interface for managing register offsets like this, but the closest thing I saw was <linux/regmap.h> which is interesting but not quite what we're looking for... Use rd32_poll_timeout() to read lock_reg and ctl_reg. Add snapshot system time for historic interpolation. Remove X86_FEATURE_ART and X86_FEATURE_TSC_KNOWN_FREQ from all E82X devices because those are SoCs, which will always have those features.

Networking changes for 6.14.
Core
----
- More core refactoring to reduce the RTNL lock contention,
including preparatory work for the per-network namespace RTNL lock,
replacing RTNL lock with a per device-one to protect NAPI-related
net device data and moving synchronize_net() calls outside such
lock.
- Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge and
more specific TCP coverage.
- Reduce network namespace tear-down time by removing per-subsystems
synchronize_net() in tipc and sched.
- Add flow label selector support for fib rules, allowing traffic
redirection based on such header field.
Netfilter
---------
- Do not remove netdev basechain when last device is gone, allowing
netdev basechains without devices.
- Revisit the flowtable teardown strategy, dealing better with fin,
reset and re-open events.
- Scale-up IP-vs connection dumping by avoiding linear search on
each restart.
Protocols
---------
- A significant XDP socket refactor, consolidating and optimizing
several helpers into the core
- Better scaling of ICMP rate-limiting, by removing false-sharing in
inet peers handling.
- Introduces netlink notifications for multicast IPv4 and IPv6
address changes.
- Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
aggregation and fragmentation of the inner IP.
- Add sysctl to configure TIME-WAIT reuse delay for TCP sockets,
to avoid local port exhaustion issues when the average connection
lifetime is very short.
- Support updating keys (re-keying) for connections using kernel
TLS (for TLS 1.3 only).
- Support ipv4-mapped ipv6 address clients in smc-r v2.
- Add support for jumbo data packet transmission in RxRPC sockets,
gluing multiple data packets in a single UDP packet.
- Support RxRPC RACK-TLP to manage packet loss and retransmission in
conjunction with the congestion control algorithm.
Driver API
----------
- Introduce a unified and structured interface for reporting PHY
statistics, exposing consistent data across different H/W via
ethtool.
- Make timestamping selectable, allow the user to select the desired
hwtstamp provider (PHY or MAC) administratively.
- Add support for configuring a header-data-split threshold (HDS)
value via ethtool, to deal with partial or buggy H/W implementation.
- Consolidate DSA drivers Energy Efficiency Ethernet support.
- Add EEE management to phylink, making use of the phylib
implementation.
- Add phylib support for in-band capabilities negotiation.
- Simplify how phylib-enabled mac drivers expose the supported
interfaces.
Tests and tooling
-----------------
- Make the YNL tool package-friendly to make it easier to deploy it
separately from the kernel.
- Increase TCP selftest coverage importing several packetdrill
test-cases.
- Regenerate the ethtool uapi header from the YNL spec,
to ease maintenance and future development.
- Add YNL support for decoding the link types used in net
self-tests, allowing a single build to run both net and
drivers/net.

Pull networking updates from Paolo Abeni:
"This is slightly smaller than usual, with the most interesting work
being still around RTNL scope reduction.
Core:
- More core refactoring to reduce the RTNL lock contention, including
preparatory work for the per-network namespace RTNL lock, replacing
RTNL lock with a per device-one to protect NAPI-related net device
data and moving synchronize_net() calls outside such lock.
- Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge
and more specific TCP coverage.
- Reduce network namespace tear-down time by removing per-subsystems
synchronize_net() in tipc and sched.
- Add flow label selector support for fib rules, allowing traffic
redirection based on such header field.
Netfilter:
- Do not remove netdev basechain when last device is gone, allowing
netdev basechains without devices.
- Revisit the flowtable teardown strategy, dealing better with fin,
reset and re-open events.
- Scale-up IP-vs connection dumping by avoiding linear search on each
restart.
Protocols:
- A significant XDP socket refactor, consolidating and optimizing
several helpers into the core
- Better scaling of ICMP rate-limiting, by removing false-sharing in
inet peers handling.
- Introduces netlink notifications for multicast IPv4 and IPv6
address changes.
- Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
aggregation and fragmentation of the inner IP.
- Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to
avoid local port exhaustion issues when the average connection
lifetime is very short.
- Support updating keys (re-keying) for connections using kernel TLS
(for TLS 1.3 only).
- Support ipv4-mapped ipv6 address clients in smc-r v2.
- Add support for jumbo data packet transmission in RxRPC sockets,
gluing multiple data packets in a single UDP packet.
- Support RxRPC RACK-TLP to manage packet loss and retransmission in
conjunction with the congestion control algorithm.
Driver API:
- Introduce a unified and structured interface for reporting PHY
statistics, exposing consistent data across different H/W via
ethtool.
- Make timestamping selectable, allow the user to select the desired
hwtstamp provider (PHY or MAC) administratively.
- Add support for configuring a header-data-split threshold (HDS)
value via ethtool, to deal with partial or buggy H/W
implementation.
- Consolidate DSA drivers Energy Efficiency Ethernet support.
- Add EEE management to phylink, making use of the phylib
implementation.
- Add phylib support for in-band capabilities negotiation.
- Simplify how phylib-enabled mac drivers expose the supported
interfaces.
Tests and tooling:
- Make the YNL tool package-friendly to make it easier to deploy it
separately from the kernel.
- Increase TCP selftest coverage importing several packetdrill
test-cases.
- Regenerate the ethtool uapi header from the YNL spec, to ease
maintenance and future development.

Kthreads affinity follow either of 4 existing different patterns:
1) Per-CPU kthreads must stay affine to a single CPU and never execute
relevant code on any other CPU. This is currently handled by smpboot
code which takes care of CPU-hotplug operations. Affinity here is
a correctness constraint.
2) Some kthreads _have_ to be affine to a specific set of CPUs and can't
run anywhere else. The affinity is set through kthread_bind_mask()
and the subsystem takes care by itself to handle CPU-hotplug
operations. Affinity here is assumed to be a correctness constraint.
3) Per-node kthreads _prefer_ to be affine to a specific NUMA node. This
is not a correctness constraint but merely a preference in terms of
memory locality. kswapd and kcompactd both fall into this category.
The affinity is set manually like for any other task and CPU-hotplug
is supposed to be handled by the relevant subsystem so that the task
is properly reaffined whenever a given CPU from the node comes up.
Also care should be taken so that the node affinity doesn't cross
isolated (nohz_full) cpumask boundaries.
4) Similar to the previous point except kthreads have a _preferred_
affinity different than a node. Both RCU boost kthreads and RCU
exp kworkers fall into this category as they refer to "RCU nodes"
from a distinctly distributed tree.
Currently the preferred affinity patterns (3 and 4) have at least 4
identified users, with more or less success when it comes to handle
CPU-hotplug operations and CPU isolation. Each of which do it in its own
ad-hoc way.
This is an infrastructure proposal to handle this with the following API
changes:
_ kthread_create_on_node() automatically affines the created kthread to
its target node unless it has been set as per-cpu or bound with
kthread_bind[_mask]() before the first wake-up.
- kthread_affine_preferred() is a new function that can be called right
after kthread_create_on_node() to specify a preferred affinity
different than the specified node.
When the preferred affinity can't be applied because the possible
targets are offline or isolated (nohz_full), the kthread is affine
to the housekeeping CPUs (which means to all online CPUs most of the
time or only the non-nohz_full CPUs when nohz_full= is set).
kswapd, kcompactd, RCU boost kthreads and RCU exp kworkers have been
converted, along with a few old drivers.
Summary of the changes:
* Consolidate a bunch of ad-hoc implementations of kthread_run_on_cpu()
* Introduce task_cpu_fallback_mask() that defines the default last
resort affinity of a task to become nohz_full aware
* Add some correctness check to ensure kthread_bind() is always called
before the first kthread wake up.
* Default affine kthread to its preferred node.
* Convert kswapd / kcompactd and remove their halfway working ad-hoc
affinity implementation
* Implement kthreads preferred affinity
* Unify kthread worker and kthread API's style
* Convert RCU kthreads to the new API and remove the ad-hoc affinity
implementation.

ice: Add in/out PTP pin delays
HW can have different input/output delays for each of the pins. Currently, only E82X adapters have delay compensation based on TSPLL config and E810 adapters have constant 1 ms compensation, both cases only for output delays and the same one for all pins. E825 adapters have different delays for SDP and other pins. Those delays are also based on direction and input delays are different than output ones. This is the main reason for moving delays to pin description structure. Add a field in ice_ptp_pin_desc structure to reflect that. Delay values are based on approximate calculations of HW delays based on HW spec. Implement external timestamp (input) delay compensation. Remove existing definitions and wrappers for periodic output propagation delays.

ice: add lock to protect low latency interface
Newer firmware for the E810 devices support a 'low latency' interface to interact with the PHY without using the Admin Queue. This is interacted with via the REG_LL_PROXY_L and REG_LL_PROXY_H registers. Currently, this interface is only used for Tx timestamps. There are two different mechanisms, including one which uses an interrupt for firmware to signal completion. However, these two methods are mutually exclusive, so no synchronization between them was necessary. This low latency interface is being extended in future firmware to support also programming the PHY timers. Use of the interface for PHY timers will need synchronization to ensure there is no overlap with a Tx timestamp. The interrupt-based response complicates the locking somewhat. We can't use a simple spinlock. This would require being acquired in ice_ptp_req_tx_single_tstamp, and released in ice_ptp_complete_tx_single_tstamp. The ice_ptp_req_tx_single_tstamp function is called from the threaded IRQ, and the ice_ptp_complete_tx_single_stamp is called from the low latency IRQ, so we would need to acquire the lock with IRQs disabled. To handle this, we'll use a wait queue along with wait_event_interruptible_locked_irq in the update flows which don't use the interrupt. The interrupt flow will acquire the wait queue lock, set the ATQBAL_FLAGS_INTR_IN_PROGRESS, and then initiate the firmware low latency request, and unlock the wait queue lock. Upon receipt of the low latency interrupt, the lock will be acquired, the ATQBAL_FLAGS_INTR_IN_PROGRESS bit will be cleared, and the firmware response will be captured, and wake_up_locked() will be called on the wait queue. The other flows will use wait_event_interruptible_locked_irq() to wait until the ATQBAL_FLAGS_INTR_IN_PROGRESS is clear. This function checks the condition under lock, but does not hold the lock while waiting. On return, the lock is held, and a return of zero indicates we hold the lock and the in-progress flag is not set. This will ensure that threads which need to use the low latency interface will sleep until they can acquire the lock without any pending low latency interrupt flow interfering.

ice: rename TS_LL_READ* macros to REG_LL_PROXY_H_*
The TS_LL_READ macros are used as part of the low latency Tx timestamp interface. A future firmware extension will add support for performing PHY timer updates over this interface. Using TS_LL_READ as the prefix for these macros will be confusing once the interface is used for other purposes. Rename the macros, using the prefix REG_LL_PROXY_H, to better clarify that this is for the low latency interface. Additionally add macros for PF_SB_ATQBAH and PF_SB_ATQBAL registers to better clarify content of this registers as PF_SB_ATQBAH contain low part of Tx timestamp Co-developed-by: Karol Kolacinski <karol.kolacinski@intel.com> Signed-off-by: Karol Kolacinski <karol.kolacinski@intel.com> Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Reviewed-by: Milena Olech <milena.olech@intel.com> Signed-off-by: Anton Nadezhdin <anton.nadezhdin@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> |

ice: Add correct PHY lane assignment
Driver always naively assumes, that for PTP purposes, PHY lane to
configure is corresponding to PF ID.
This is not true for some port configurations, e.g.:
- 2x50G per quad, where lanes used are 0 and 2 on each quad, but PF IDs
are 0 and 1
- 100G per quad on 2 quads, where lanes used are 0 and 4, but PF IDs are
0 and 1
Use correct PHY lane assignment by getting and parsing port options.
This is read from the NVM by the FW and provided to the driver with
the indication of active port split.
Remove ice_is_muxed_topo(), which is no longer needed.

treewide: Introduce kthread_run_worker[_on_cpu]()
kthread_create() creates a kthread without running it yet. kthread_run() creates a kthread and runs it. On the other hand, kthread_create_worker() creates a kthread worker and runs it. This difference in behaviours is confusing. Also there is no way to create a kthread worker and affine it using kthread_bind_mask() or kthread_affine_preferred() before starting it. Consolidate the behaviours and introduce kthread_run_worker[_on_cpu]() that behaves just like kthread_run(). kthread_create_worker[_on_cpu]() will now only create a kthread worker without starting it.

PTP pins assignment and their related SDPs (Software Definable Pins) are currently hardcoded. Fix that by reading NVM section instead on products supporting this, which are E810 products. If SDP section is not defined in NVM, the driver continues to use the hardcoded table.

Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.

Networking changes for 6.11. Not much excitement - a handful of large
patchsets (devmem among them) did not make it in time.
Core & protocols
----------------
- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT.
- Use flex array for netdevice priv area, ensure its cache alignment.
- Add a sysctl knob to allow user to specify a default rto_min at socket
init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful.
- Support scheduling transmission of packets based on CLOCK_TAI.
- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned off
using cpusets.
- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address.
- Allow configuration of multipath hash seed, to both allow synchronizing
hashing of two routers, and preventing partial accidental sync.
- Improve TCP compliance with RFC 9293 for simultaneous connect().
- Support sending NAT keepalives in IPsec ESP in UDP states. Userspace
IKE daemon had to do this before, but the kernel can better keep
track of it.
- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled.
- Introduce IPPROTO_SMC for selecting SMC when socket is created.
- Allow UDP GSO transmit from devices with no checksum offload.
- openvswitch: add packet sampling via psample, separating the sampled
traffic from "upcall" packets sent to user space for forwarding.
- nf_tables: shrink memory consumption for transaction objects.
Things we sprinkled into general kernel code
--------------------------------------------
- Power Sequencing subsystem (used by Qualcomm Bluetooth driver
for QCA6390).
- Add IRQ information in sysfs for auxiliary bus.
- Introduce guard definition for local_lock.
- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures.
BPF
---
- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered.
- Add new kfuncs for a generic, open-coded bits iterator.
- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head.
- Support resilient split BTF which cuts down on duplication and makes
BTF as compact as possible WRT BTF from modules.
- Add support for dumping kfunc prototypes from BTF which enables both
detecting as well as dumping compilable prototypes for kfuncs.
- riscv64 BPF JIT improvements in particular to add 12-argument support
for BPF trampolines and to utilize bpf_prog_pack for the latter.
- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs.
Driver API
----------
- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose.
- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits.
- Track additional RSS contexts in the core, make sure configuration
changes don't break them.
- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated ESP
data paths.
- Support updating firmware on SFP modules.
Tests and tooling
-----------------
- mptcp: use net/lib.sh to manage netns.
- TCP-AO and TCP-MD5: replace debug prints used by tests with
tracepoints.
- openvswitch: make test self-contained (don't depend on OvS CLI tools).

ice: Reject pin requests with unsupported flags
The driver receives requests for configuring pins via the .enable
callback of the PTP clock object. These requests come into the driver
with flags which modify the requested behavior from userspace. Current
implementation in ice does not reject flags that it doesn't support.
This causes the driver to incorrectly apply requests with such flags as
PTP_PEROUT_DUTY_CYCLE, or any future flags added by the kernel which it
is not yet aware of.
Fix this by properly validating flags in both ice_ptp_cfg_perout and
ice_ptp_cfg_extts. Ensure that we check by bit-wise negating supported
flags rather than just checking and rejecting known un-supported flags.
This is preferable, as it ensures better compatibility with future
kernels.

ice: Don't process extts if PTP is disabled
The ice_ptp_extts_event() function can race with ice_ptp_release() and
result in a NULL pointer dereference which leads to a kernel panic.
Panic occurs because the ice_ptp_extts_event() function calls
ptp_clock_event() with a NULL pointer. The ice driver has already
released the PTP clock by the time the interrupt for the next external
timestamp event occurs.
To fix this, modify the ice_ptp_extts_event() function to check the
PTP state and bail early if PTP is not ready.

ice: Fix improper extts handling
Extts events are disabled and enabled by the application ts2phc.
However, in case where the driver is removed when the application is
running, a specific extts event remains enabled and can cause a kernel
crash.
As a side effect, when the driver is reloaded and application is started
again, remaining extts event for the channel from a previous run will
keep firing and the message "extts on unexpected channel" might be
printed to the user.
To avoid that, extts events shall be disabled when PTP is released.

auxbus: make to_auxiliary_drv accept and return a constant pointer
In the quest to make struct device constant, start by making to_auxiliary_drv() return a constant pointer so that drivers that call this can be fixed up before the driver core changes. As the return type previously was not constant, also fix up all callers that were assuming that the pointer was not going to be a constant one in order to not break the build.

ice: add and use roundup_u64 instead of open coding equivalent
In ice_ptp_cfg_clkout(), the ice driver needs to calculate the nearest next second of a current time value specified in nanoseconds. It implements this using div64_u64, because the time value is a u64. It could use div_u64 since NSEC_PER_SEC is smaller than 32-bits. Ideally this would be implemented directly with roundup(), but that can't work on all platforms due to a division which requires using the specific macros and functions due to platform restrictions, and to ensure that the most appropriate and fast instructions are used. The kernel doesn't currently provide any 64-bit equivalents for doing roundup. Attempting to use roundup() on a 32-bit platform will result in a link failure due to not having a direct 64-bit division. The closest equivalent for this is DIV64_U64_ROUND_UP, which does a division always rounding up. However, this only computes the division, and forces use of the div64_u64 in cases where the divisor is a 32bit value and could make use of div_u64. Introduce DIV_U64_ROUND_UP based on div_u64, and then use it to implement roundup_u64 which takes a u64 input value and a u32 rounding value. The name roundup_u64 matches the naming scheme of div_u64, and future patches could implement roundup64_u64 if they need to round by a multiple that is greater than 32-bits. Replace the logic in ice_ptp.c which does this equivalent with the newly added roundup_u64.

ice: Adjust PTP init for 2x50G E825C devices
>From FW/HW perspective, 2 port topology in E825C devices requires merging of 2 port mapping internally and breakout mapping externally. As a consequence, it requires different port numbering from PTP code perspective. For that topology, pf_id can not be used to index PTP ports. Even if the 2nd port is identified as port with pf_id = 1, all PHY operations need to be performed as it was port 2. Thus, special mapping is needed for the 2nd port. This change adds detection of 2x50G topology and applies 'custom' mapping on the 2nd port.
