As kernel test robot reported, lib/test_objpool.c (trace:probes/for-next)
has linux/version.h included, but version.h is not used at all. Then more
unused headers are found in test_objpool.c and rethook.c, and all of them
should be removed.

The OP-TEE driver using the old SMC based ABI permits overlapping shared
buffers, but with the new FF-A based ABI each physical page may only
be registered once.
As the key and blob buffer are allocated adjancently, there is no need
for redundant register shared memory invocation. Also, it is incompatibile
with FF-A based ABI limitation. So refactor register shared memory
implementation to use only single invocation to register both key and blob
buffers.

alongside with shared netlink attribute policy.
Patches #1-#6 are just small preparations and small fixes on multiple
places. Note that couple of patches contain the "Fixes"

Patch #7 is a simple rename preparation
Patch #8 is the main one in this set and adds actual definitions of cmds

The HW must be programmed differently for queue-based scheduling mode.
To program the completion queue context correctly, the control plane
must know the scheduling mode not only for the Tx queue, but also for

Unfortunately, currently the driver sets the scheduling mode only for
the Tx queues.

Ports 5 and 7 are disabled by default because the standard use case is
for port 8 to manage all CPU directed traffic. For experimentation
purposes however it is desirable to provide adequate properties such

not limited to doubling or tripling the bandwidth by leveraging the

When redescribing ports I assumed that missing "label" (like "cpu")
means switch port isn't used. That was incorrect and I realized my
change made Linux always use the first (5) CPU port (there are 3 of
them).
While above should technically be possible it often isn't correct:
1. Non-default switch ports are often connected to Ethernet interfaces
not fully covered by vendor setup (they may miss MACs)
2. On some devices non-default ports require specifying fixed link
This fixes network connectivity for some devices. It was reported &
tested for Netgear R8000. It also affects Linksys EA9200 with its

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
This patch replaces 3 callsites of strncpy().
The first two populate the destination buffer `nsm.name` -- which we
expect to be NUL-terminated based on their use with format strings.
Firstly, as I understand it, virtio_rpmsg_announce_create() creates an
rpmsg_ns_msg and sends via:
virtio_rpmsg_bus.c:
336: err = rpmsg_sendto(rpdev->ept, &nsm, sizeof(nsm), RPMSG_NS_ADDR);
... which uses:
virtio_rpmsg_sendto() -> rpmsg_send_offchannel_raw()
... which copies its data into an rpmsg_hdr `msg` in virtio_rpmsg_bus.c
618: memcpy(msg->data, data, len);
This callback is invoked when a message is received from the remote
processor:
rpmsg_ns.c:
30: /* invoked when a name service announcement arrives */
31: static int rpmsg_ns_cb(struct rpmsg_device *rpdev, void *data, int len,
32: void *priv, u32 src)
33: {
34: struct rpmsg_ns_msg *msg = data;
...
50: /* don't trust the remote processor for null terminating the name */
51: msg->name[RPMSG_NAME_SIZE - 1] = '\0';
... which leads into the use of `name` within a format string:
rpmsg_ns.c:
57: dev_info(dev, "%sing channel %s addr 0x%x\n",
58: rpmsg32_to_cpu(rpdev, msg->flags) & RPMSG_NS_DESTROY ?
59: "destroy" : "creat", msg->name, chinfo.dst);
We can also observe that `nsm` is not zero-initialized and as such we
should maintain the NUL-padding behavior that strncpy() provides:
virtio_rpmsg_bus.c:
330: struct rpmsg_ns_msg nsm;
Considering the above, a suitable replacement is `strscpy_pad` due to
the fact that it guarantees both NUL-termination and NUL-padding on the
destination buffer.
Now, for the third and final destination buffer rpdev->id.name we can
just go for strscpy() (not _pad()) as rpdev points to &vch->rpdev:
| rpdev = &vch->rpdev;
... and vch is zero-allocated:
| vch = kzalloc(sizeof(*vch), GFP_KERNEL);
... this renders any additional NUL-byte assignments (like the ones
strncpy() or strscpy_pad() does) redundant.

We currently have a global VTCR_EL2 value for each guest, even
if the guest uses NV. This implies that the guest's own S2 must
fit in the host's. This is odd, for multiple reasons:
- the PARange values and the number of IPA bits don't necessarily
match: you can have 33 bits of IPA space, and yet you can only
describe 32 or 36 bits of PARange
- When userspace set the IPA space, it creates a contract with the
kernel saying "this is the IPA space I'm prepared to handle".
At no point does it constraint the guest's own IPA space as
long as the guest doesn't try to use a [I]PA outside of the
IPA space set by userspace
- We don't even try to hide the value of ID_AA64MMFR0_EL1.PARange.
And then there is the consequence of the above: if a guest tries
to create a S2 that has for input address something that is larger
than the IPA space defined by the host, we inject a fatal exception.
This is no good. For all intent and purposes, a guest should be
able to have the S2 it really wants, as long as the *output* address
of that S2 isn't outside of the IPA space.
For that, we need to have a per-s2_mmu VTCR_EL2 setting, which
allows us to represent the full PARange. Move the vctr field into
the s2_mmu structure, which has no impact whatsoever, except for NV.
Note that once we are able to override ID_AA64MMFR0_EL1.PARange
from userspace, we'll also be able to restrict the size of the
shadow S2 that NV uses.

Variable d_len_code is being initialized to zero and then re-assigned a
different value in all the valid cases in the following switch statement.
The only place it is not being assigned a value is on the return for
a default case and in this case it does not need to be assigned. The
initialization is redundant and can be removed.

The driver is now built only when MACH_AMS_DELTA is selected, which
requires a very specific selection of ARCH settings. As a consequence, it
gets very little attention from build-bots, if not none.
Drop the driver dependency on <asm/mach-types.h>, no longer required since
conversion to snd_soc_register_card() and drop of machine_is_ams_delta().
With that in place, allow the driver to be built in any environment as
long as COMPILE_TEST is selected. Take care of not selecting
SND_SOC_OMAP_MCBSP if COMMON_CLK is not selected.

Merge changes in Intel thermal control drivers for 6.7-rc1:
- Add power floor notifications support to the int340x thermal control
driver (Srinivas Pandruvada).
- Rework updating trip points in the int340x thermal driver so that it
does not access thermal zone internals directly (Rafael Wysocki).
- Use param_get_byte() instead of param_get_int() as the max_idle module
parameter .get() callback in the Intel powerclamp thermal driver to
avoid possible out-of-bounds access (David Arcari).
- Add workload hints support to the the int340x thermal driver (Srinivas
Pandruvada).

syzbot reports a slab use-after-free in hci_conn_hash_flush [1].
After releasing an object using hci_conn_del_sysfs in the
hci_conn_cleanup function, releasing the same object again
using the hci_dev_put and hci_conn_put functions causes a double free.
Here's a simplified flow:
hci_conn_del_sysfs:
hci_dev_put
put_device
kobject_put
kref_put
kobject_release
kobject_cleanup
kfree_const
kfree(name)
hci_dev_put:
...
kfree(name)
hci_conn_put:
put_device
...
kfree(name)
This patch drop the hci_dev_put and hci_conn_put function
call in hci_conn_cleanup function, because the object is
freed in hci_conn_del_sysfs function.
This patch also fixes the refcounting in hci_conn_add_sysfs() and
hci_conn_del_sysfs() to take into account device_add() failures.
This fixes CVE-2023-28464.
