SPS OCP (over current protection) is a mechanism to cut off power to

Tomonori writes:
"This adds the Rust equivalent of the C's DO_ONCE_LITE and pr_*_once
macros.
A proposal for this feature was made in the past [1], but it didn't
reach consensus on the implementation and wasn't merged.
Unlike the previous proposal, this implements the C's DO_ONCE_LITE
mechanism using a single atomic variable. While it would be possible
to implement the feature entirely as a Rust macro, the functionality
that can be implemented as regular functions has been extracted and
implemented as the OnceLite struct for better code readability.
To make it clear that this feature is intended solely for
print-related functionality (just like in C), the implementation is
placed in print.rs. If an equivalent of std::sync::Once is needed in
the future, it should be based on SetOnce rather than OnceLite. Unlike
std::sync::Once and SetOnce, OnceLite only manages two states:
incomplete and complete.
The do_once_lite macro places the OnceLite object in the .data..once
section, which may be zeroed by memset at any time. While this means
tear reads might happen, OnceLite only manages two states (zero and
non-zero), so no actual problem occurs in practice.
OnceLite currently uses Atomic<i32>, but may be changed to use
Atomic<i8> [2] when it becomes available."

Update Documentation/security/keys/trusted-encrypted.rst and Documentation/

The wrapping key does not exist by default and is generated by the
hypervisor as a part of PKWM initialization. This key is then persisted by
the hypervisor and is used to wrap trusted keys. These are variable length
symmetric keys, which in the case of PowerVM Key Wrapping Module (PKWM) are
generated using the kernel RNG. PKWM can be used as a trust source through
the following example keyctl commands:
keyctl add trusted my_trusted_key "new 32" @u
Use the wrap_flags command option to set the secure boot requirement for
the wrapping request through the following keyctl commands
case1: no secure boot requirement. (default)
keyctl usage: keyctl add trusted my_trusted_key "new 32" @u
OR
keyctl add trusted my_trusted_key "new 32 wrap_flags=0x00" @u
case2: secure boot required to in either audit or enforce mode. set bit 0
keyctl usage: keyctl add trusted my_trusted_key "new 32 wrap_flags=0x01" @u
case3: secure boot required to be in enforce mode. set bit 1
keyctl usage: keyctl add trusted my_trusted_key "new 32 wrap_flags=0x02" @u
NOTE:
-> Setting the secure boot requirement is NOT a must.
-> Only either of the secure boot requirement options should be set. Not
both.
-> All the other bits are required to be not set.
-> Set the kernel parameter trusted.source=pkwm to choose PKWM as the
backend for trusted keys implementation.
-> CONFIG_PSERIES_PLPKS must be enabled to build PKWM.
Add PKWM, which is a combination of IBM PowerVM and Power LPAR Platform
KeyStore, as a new trust source for trusted keys.

The hypervisor generated wrapping key is an AES-GCM-256 symmetric key which
is stored in a non-volatile, secure, and encrypted storage called the Power
LPAR Platform KeyStore. It has policy based protections that prevent it
from being read out or exposed to the user.
Implement H_PKS_GEN_KEY, H_PKS_WRAP_OBJECT, and H_PKS_UNWRAP_OBJECT HCALLs
to enable using the PowerVM Key Wrapping Module (PKWM) as a new trust
source for trusted keys. Disallow H_PKS_READ_OBJECT, H_PKS_SIGNED_UPDATE,
and H_PKS_WRITE_OBJECT for objects with the 'wrapping key' policy set.

The IRQ handler extracts if_id from the upper 16 bits of the hardware
status register and uses it to index into ethsw->ports[] without
validation. Since if_id can be any 16-bit value (0-65535) but the ports
array is only allocated with sw_attr.num_ifs elements, this can lead to
an out-of-bounds read potentially.
Add a bounds check before accessing the array, consistent with the
existing validation in dpaa2_switch_rx().

net: liquidio: Fix memory leaks in setup_nic_devices()
This series fixes memory leaks in the initialization paths of the
NIC devices.
Patch 1 moves the initialization of oct->props[i].netdev before queue
setup calls. This ensures that if queue setup fails, the cleanup function
can find and free the allocated netdev. It also initializes lio->oct_dev
early to prevent a crash in the cleanup path.
Patch 2 fixes an off-by-one error in the PF cleanup loop. It ensures
the current device index is cleaned up and correctly handles the
post-loop devlink_alloc failure case.
Patch 3 fixes the same off-by-one error in the VF cleanup loop.

In setup_nic_devices(), the netdev is allocated using alloc_etherdev_mq().
However, the pointer to this structure is stored in oct->props[i].netdev
only after the calls to netif_set_real_num_rx_queues() and
netif_set_real_num_tx_queues().
If either of these functions fails, setup_nic_devices() returns an error
without freeing the allocated netdev. Since oct->props[i].netdev is still
NULL at this point, the cleanup function liquidio_destroy_nic_device()
will fail to find and free the netdev, resulting in a memory leak.
Fix this by initializing oct->props[i].netdev before calling the queue
setup functions. This ensures that the netdev is properly accessible for
cleanup in case of errors.

and code review.

====================
Airoha AN8811HB 2.5 Gbps phy support
The RFC patch posted earlier has been split into a series based on the
feedback received:
1/3: preparing the EN8811H driver for maximum reuse
2/3: adding support for the new AN8811HB hardware
3/3: adding (optional) clock driver for AN8811HB
Patch 3/3 is not required for a functional device. It is included here
for full feature parity between the EN8811H and AN8811HB drivers.
The AN8811HB phy requires new firmware, which is now available with
the 20260110 release of linux-firmware,

The Airoha AN8811HB is mostly compatible with the EN8811H, adding 10Base-T
support and reducing power consumption.
This driver is based on the air_an8811hb v0.0.4 out-of-tree driver
written by "Lucien.Jheng <lucien.jheng@airoha.com>"
Firmware is available in linux-firmware. The driver has been tested with
firmware version 25110702

Commit 1ceeedb59749 ("ublk: optimize UBLK_IO_UNREGISTER_IO_BUF on daemon
task") optimized ublk request buffer unregistration to use a non-atomic
reference count decrement when performed on the ublk_io's daemon task.
The optimization applied to auto buffer unregistration, which happens as
part of handling UBLK_IO_COMMIT_AND_FETCH_REQ on the daemon task.
However, commit b749965edda8 ("ublk: remove ublk_commit_and_fetch()")
reordered the ublk_sub_req_ref() for the completed request before the
io_buffer_unregister_bvec() call. As a result, task_registered_buffers
is already 0 when io_buffer_unregister_bvec() calls ublk_io_release()
and the non-atomic refcount optimization doesn't apply.
Move the io_buffer_unregister_bvec() call back to before
ublk_need_complete_req() to restore the reference counting optimization.

The driver now depends on the core to tell it what the rx page size
should be for the agg ring. We must populate the ndo_default_qcfg
callback even if we don't support any queue ops.
This fixes:

use "size * sizeof(u64)" in hinic3_feature_nego.
Use array_size instead of multiplying can make it clearer.

Instead of using generic workqueue, use a dedicated kthread for optimizing
kprobes, because it can wait (sleep) for a long time inside the process
by synchronize_rcu_task(). This means other works can be stopped until it
finishes.

fl6_update_dst() is called for every TCP (and others) transmit,
and is a nop for common cases.
Split it in two parts :
1) fl6_update_dst() inline helper, small and fast.
2) __fl6_update_dst() for the exception, out of line.
Small size increase to get better TX performance.
