Trusted keys unseal the key blob on load, but keep the sealed payload in
the blob field so that every subsequent read (export) will simply
convert this field to hex and send it to userspace.

With DCP-based trusted keys, we decrypt the blob encryption key (BEK)
in the Kernel due hardware limitations and then decrypt the blob payload.
BEK decryption is done in-place which means that the trusted key blob
field is modified and it consequently holds the BEK in plain text.
Every subsequent read of that key thus send the plain text BEK instead
of the encrypted BEK to userspace.

This issue only occurs when importing a trusted DCP-based key and
then exporting it again. This should rarely happen as the common use cases
are to either create a new trusted key and export it, or import a key
blob and then just use it without exporting it again.

Fix this by performing BEK decryption and encryption in a dedicated
buffer. Further always wipe the plain text BEK buffer to prevent leaking
the key via uninitialized memory.

The DCP trusted key type uses the wrong helper function to store

Fix by using correct helper function.

 - Revert a recent change to sense data generation.

   Sense data can be in either fixed format or descriptor format.

   The D_SENSE bit in the Control mode page controls which format to
   generate. All places but one respected the D_SENSE bit.

   The recent change fixed the one place that didn't respect the D_SENSE
   bit. However, it turns out that hdparm, hddtemp and udisks
   (incorrectly) assumes sense data in descriptor format.

   Therefore, even while the change was technically correct, revert it,
   since even if these user space programs are fixed to (correctly) look
   at the format type before parsing the data, older versions of these
   tools will be around roughly forever.

With CONFIG_LTO_CLANG=y, the compiler may add .llvm.<hash> suffix to
function names to avoid duplication. APIs like kallsyms_lookup_name()
and kallsyms_on_each_match_symbol() tries to match these symbol names
without the .llvm.<hash> suffix, e.g., match "c_stop" with symbol
c_stop.llvm.17132674095431275852. This turned out to be problematic
for use cases that require exact match, for example, livepatch.

Fix this by making the APIs to match symbols exactly.

Also cleanup kallsyms_selftests accordingly.

Having two methods to wait on GT TLB invalidations is not ideal. Remove
xe_gt_tlb_invalidation_wait and only use GT TLB invalidation fences.

In addition to two methods being less than ideal, once GT TLB
invalidations are coalesced the seqno cannot be assigned during
xe_gt_tlb_invalidation_ggtt/range. Thus xe_gt_tlb_invalidation_wait
would not have a seqno to wait one. A fence however can be armed and
later signaled.

When validating VF config on the media GT, we may wrongly report
that VF is already partially configured on it, as we consider GGTT
and LMEM provisioning done on the primary GT (since both GGTT and
LMEM are tile-level resources, not a GT-level).

This will cause skipping a VF auto-provisioning on the media-GT and
in result will block a VF from successfully initialize that GT.

Fix that by considering GGTT and LMEM configurations only when
checking if a VF provisioning is complete, and omit GGTT and LMEM
when reporting empty/partial provisioning.

xe_file_close triggers an asynchronous queue cleanup and then frees up
the xef object. Since queue cleanup flushes all pending jobs and the KMD
stores client usage stats into the xef object after jobs are flushed, we
see a use-after-free for the xef object. Resolve this by taking a
reference to xef from xe_exec_queue.

Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Ignores ifindex for types other than mcast/linklocal in ipv6 frag
   reasm, from Tom Hughes.

2) Initialize extack for begin/end netlink message marker in batch,
   from Donald Hunter.

3) Initialize extack for flowtable offload support, also from Donald.

4) Dropped packets with cloned unconfirmed conntracks in nfqueue,
   later it should be possible to explore lookup after reinject but
   Florian prefers this approach at this stage. From Florian Westphal.

5) Add selftest for cloned unconfirmed conntracks in nfqueue for
   previous update.

6) Audit after filling netlink header successfully in object dump,
   from Phil Sutter.

7-8) Fix concurrent dump and reset which could result in underflow
     counter / quota objects.

In reset process, the driver will DOWN the port and then UINIT, in this
case, the setup tc process will UP the port before UINIT, so cause the
problem. Adds a DOWN process in UINIT to fix it.

Consider the followed case that the user change speed and reset the net
interface. Before the hw change speed successfully, the driver get old
old speed from hw by timer task. After reset, the previous speed is config
to hw. As a result, the new speed is configed successfully but lost after
PF reset. The followed pictured shows more dirrectly.

Currently, if hns3 PF or VF FLR reset failed after five times retry,
the reset done process will directly release the semaphore
which has already released in hclge_reset_prepare_general.
This will cause down operation fail.

So this patch fixes it by adding reset state judgement. The up operation is
only called after successful PF FLR reset.

When deleting netns, it is possible to still have some tasks running,
e.g. background tasks like tcpdump running in the background, not
stopped because the test has been interrupted.

Before deleting the netns, it is then safer to kill all attached PIDs,
if any. That should reduce some noises after the end of some tests, and
help with the debugging of some issues. That's why this modification is
seen as a "fix".

Fix an issue where `devm_regulator_register()` would fail for PSE
controllers that do not support current limit control, such as simple
GPIO-based controllers like the podl-pse-regulator. The
`REGULATOR_CHANGE_CURRENT` flag and `max_uA` constraint are now
conditionally set only if the `pi_set_current_limit` operation is
supported. This change prevents the regulator registration routine from
attempting to call `pse_pi_set_current_limit()`, which would return
`-EOPNOTSUPP` and cause the registration to fail.
