Commit 8a0ec8c2d7 ("spi: Insert the missing pci_dev_put()before
return") added two uses of pci_dev_put() with an uninitialized dma_dev,
resulting in the following compiler warnings (or errors with
CONFIG_WERROR) when building with clang:
drivers/spi/spi-pxa2xx-pci.c:150:15: error: variable 'dma_dev' is uninitialized when used here [-Werror,-Wuninitialized]
150 | pci_dev_put(dma_dev);

Commit 609d7ffdc4 ("spi: pxa2xx-pci: Balance reference count for PCI
DMA device") added a call to pci_dev_put() via
devm_add_action_or_reset() in case of failures, so the recent change was
incorrect for multiple reasons. Revert it altogether.

When removing a resource from vmci_resource_table in
vmci_resource_remove(), the search is performed using the resource
handle by comparing context and resource fields.
It is possible though to create two resources with different types
but same handle (same context and resource fields).
When trying to remove one of the resources, vmci_resource_remove()
may not remove the intended one, but the object will still be freed
as in the case of the datagram type in vmci_datagram_destroy_handle().
vmci_resource_table will still hold a pointer to this freed resource
leading to a use-after-free vulnerability.

devm_free_percpu() calls devres_release() with a pointer in percpu
address space. devres_release() expects pointers in the generic address
space, so address space needs to be stripped from the argument.
When strict percpu address space checks are enabled, then the current
direct cast from the percpu address space to the generic address space
fails the compilation on x86_64 with:
devres.c🔢32: error: cast to generic address space pointer from disjoint ‘__seg_gs’ address space pointer
Add intermediate casts to unsigned long to remove address space of
the pointer before casting it to the generic AS, as advised in [1]
and [2].
Side note: sparse still requires __force, although the documentation
[2] allows casts to unsigned long without __force attribute.
Found by GCC's named address space checks.
There were no changes in the resulting object file.

Add code to allow asynchronous shutdown of devices, ensuring that each
device is shut down before its parents & suppliers.
Only devices with drivers that have async_shutdown_enable enabled will be
shut down asynchronously.
This can dramatically reduce system shutdown/reboot time on systems that
have multiple devices that take many seconds to shut down (like certain
NVMe drives). On one system tested, the shutdown time went from 11 minutes
without this patch to 55 seconds with the patch.

The sctp selftest is very slow on debug kernels.
Its possible that the nf_queue listener program exits due to timeout
before first sctp packet is processed.
In this case socat hangs until script times out.
Fix this by removing the -t option where possible and kill the test
program once the file transfer/socat has exited.
-t sets SO_RCVTIMEO, its inteded for the 'ping' part of the selftest
where we want to make sure that packets get reinjected properly without
skipping a second queue request.
While at it, add a helper to compare the (binary) files instead of diff.
The 'diff' part was copied from a another sub-test that compares text.
Let helper dump file sizes on error so we can see the progress made.
Tested on an old 2010-ish box with a debug kernel and 100 iterations.
This is a followup to the earlier filesize reduction change.

Device class has two namespace relevant fields which are usually
associated by the following usage:
struct class {
...
const struct kobj_ns_type_operations *ns_type;
const void *(*namespace)(const struct device *dev);
...
}
if (dev->class && dev->class->ns_type)
dev->class->namespace(dev);
(1) The usage looks weird since it checks @ns_type but calls namespace()
(2) The usage implies both fields have dependency but their dependency
is not currently enforced yet.
It is found for all existing class definitions that the other filed is
also assigned once one is assigned in current kernel tree.
Fixed by enforcing above existing dependency that both fields are required
for a device class to support namespace via parameter checks.

There are several drivers/base APIs for finding a specific device, and
they currently use the following good type for the @match parameter:
int (*match)(struct device *dev, const void *data)
Since these operations do not modify the caller-provided @*data, this
type is worthy of a dedicated typedef:
typedef int (*device_match_t)(struct device *dev, const void *data)
Advantages of using device_match_t:
- Shorter API declarations and definitions
- Prevent further APIs from using a bad type for @match
So introduce device_match_t and apply it to the existing
(bus|class|driver|auxiliary)_find_device() APIs.

Most firmware names are hardcoded strings, or are constructed from fairly
constrained format strings where the dynamic parts are just some hex
numbers or such.
However, there are a couple codepaths in the kernel where firmware file
names contain string components that are passed through from a device or
semi-privileged userspace; the ones I could find (not counting interfaces
that require root privileges) are:
- lpfc_sli4_request_firmware_update() seems to construct the firmware
filename from "ModelName", a string that was previously parsed out of
some descriptor ("Vital Product Data") in lpfc_fill_vpd()
- nfp_net_fw_find() seems to construct a firmware filename from a model
name coming from nfp_hwinfo_lookup(pf->hwinfo, "nffw.partno"), which I
think parses some descriptor that was read from the device.
(But this case likely isn't exploitable because the format string looks
like "netronome/nic_%s", and there shouldn't be any *folders* starting
with "netronome/nic_". The previous case was different because there,
the "%s" is *at the start* of the format string.)
- module_flash_fw_schedule() is reachable from the
ETHTOOL_MSG_MODULE_FW_FLASH_ACT netlink command, which is marked as
GENL_UNS_ADMIN_PERM (meaning CAP_NET_ADMIN inside a user namespace is
enough to pass the privilege check), and takes a userspace-provided
firmware name.
(But I think to reach this case, you need to have CAP_NET_ADMIN over a
network namespace that a special kind of ethernet device is mapped into,
so I think this is not a viable attack path in practice.)
Fix it by rejecting any firmware names containing ".." path components.
For what it's worth, I went looking and haven't found any USB device
drivers that use the firmware loader dangerously.

Rescind offer handling relies on rescind callbacks for some of the
resources cleanup, if they are registered. It does not unregister
vmbus device for the primary channel closure, when callback is
registered. Without it, next onoffer does not come, rescind flag
remains set and device goes to unusable state.
Add logic to unregister vmbus for the primary channel in rescind callback
to ensure channel removal and relid release, and to ensure that next
onoffer can be received and handled properly.

For primary VM Bus channels, primary_channel pointer is always NULL. This

is meant for primary channels only.

In parport_attach, the return value of ida_alloc is unchecked, witch leads
to the use of an invalid index value.
To address this issue, index should be checked. When the index value is
