Same as initial tests, import verbatim from
github.com/google/packetdrill, aside from:
- update `source ./defaults.sh` path to adjust for flat dir
- add SPDX headers
- remove author statements if any
- drop blank lines at EOF (new)
Also import set_sysctls.py, which many scripts depend on to set
sysctls and then restore them later. This is no longer strictly needed
for namespacified sysctl. But not all sysctls are namespacified, and
doesn't hurt if they are.

Run packetdrill tests inside netns.
They may change system settings, such as sysctl.
Also expand config with a few more needed CONFIGs.

ENA currently supports the following customer metrics:
- `bw_in_allowance_exceeded`
- `bw_out_allowance_exceeded`
- `conntrack_allowance_exceeded`
- `linklocal_allowance_exceeded`
- `pps_allowance_exceeded`
This patch adds a new metric named:
`conntrack_allowance_available`.
Information about these metrics is available in [1].
In addition, the interface between the driver and the
device has been upgraded to allow more flexibility and
expendability to additional metrics in the future.

As Jann points out, PFN mappings are special, because unlike normal
memory mappings, there is no lifetime information associated with the
mapping - it is just a raw mapping of PFNs with no reference counting of
a 'struct page'.
That's all very much intentional, but it does mean that it's easy to
mess up the cleanup in case of errors. Yes, a failed mmap() will always
eventually clean up any partial mappings, but without any explicit
lifetime in the page table mapping itself, it's very easy to do the
error handling in the wrong order.
In particular, it's easy to mistakenly free the physical backing store
before the page tables are actually cleaned up and (temporarily) have
stale dangling PTE entries.
To make this situation less error-prone, just make sure that any partial
pfn mapping is torn down early, before any other error handling.

Buffers can get registered with io_uring, which allows to skip the
repeated pin_pages, unpin/unref pages for each O_DIRECT operation. This
reduces the overhead of O_DIRECT IO.
However, registrering buffers can take some time. Normally this isn't an
issue as it's done at initialization time (and hence less critical), but
for cases where rings can be created and destroyed as part of an IO
thread pool, registering the same buffers for multiple rings become a
more time sensitive proposition. As an example, let's say an application
has an IO memory pool of 500G. Initial registration takes:
Got 500 huge pages (each 1024MB)
Registered 500 pages in 409 msec
or about 0.4 seconds. If we go higher to 900 1GB huge pages being
registered:
Registered 900 pages in 738 msec
which is, as expected, a fully linear scaling.
Rather than have each ring pin/map/register the same buffer pool,
provide an io_uring_register(2) opcode to simply duplicate the buffers
that are registered with another ring. Adding the same 900GB of
registered buffers to the target ring can then be accomplished in:
Copied 900 pages in 17 usec
While timing differs a bit, this provides around a 25,000-40,000x
speedup for this use case.

Can be done in one of two ways:
1) Regular file descriptor, just fget()
2) Registered ring, index our own table for that

register syscall as well.

The fallback S/G buffer allocation for x86 used the addresses deduced
from the page allocations blindly. It broke the allocations on IOMMU
and made us to work around with a hackish DMA ops check.
For cleaning up those messes, this patch switches to the proper DMA
mapping API usages with the standard sg-table instead.
By introducing the sg-table, the address table isn't needed, but for
keeping the original allocation sizes for freeing, replace it with the
array keeping the number of pages.
The get_addr callback is changed to use the existing one for
non-contiguous buffers. (Also it's the reason sg_table is put at the
beginning of struct snd_dma_sg_fallback.)
And finally, the hackish workaround that checks the DMA ops is
dropped now.

compile_commands.json is used by clangd[1] to provide code navigation
and completion functionality to editors. See [2] for an example
configuration that includes this functionality for VSCode.
It can currently be built manually when using kunit.py, by running:
./scripts/clang-tools/gen_compile_commands.py -d .kunit
With this change however, it's built automatically so you don't need to
manually keep it up to date.
Unlike the manual approach, having make build the compile_commands.json
means that it appears in the build output tree instead of at the root of
the source tree, so you'll need to add --compile-commands-dir=.kunit to
your clangd args for it to be found. This might turn out to be pretty
annoying, I'm not sure yet. If so maybe we can later add some hackery to
kunit.py to work around it.

This patch aims to allocate bvpages and short-lived compressed pages
from the reserved pool first.
After applying this patch, there are three benefits.
1. It reduces the page allocation time.
The bvpages and short-lived compressed pages account for about 4% of
the pages allocated from the system in the multi-app launch benchmarks
[1]. It reduces the page allocation time accordingly and lowers the
likelihood of blockage by page allocation in low memory scenarios.
2. The pages in the reserved pool will be allocated on demand.
Currently, bvpages and short-lived compressed pages are short-lived
pages allocated from the system, and the pages in the reserved pool all
originate from short-lived pages. Consequently, the number of reserved
pool pages will increase to z_erofs_rsv_nrpages over time.
With this patch, all short-lived pages are allocated from the reserved
pool first, so the number of reserved pool pages will only increase when
there are not enough pages. Thus, even if z_erofs_rsv_nrpages is set to
a large number for specific reasons, the actual number of reserved pool
pages may remain low as per demand. In the multi-app launch benchmarks
[1], z_erofs_rsv_nrpages is set at 256, while the number of reserved
pool pages remains below 64.
3. When erofs cache decompression is disabled
(EROFS_ZIP_CACHE_DISABLED), all pages will *only* be allocated from
the reserved pool for erofs. This will significantly reduce the memory
pressure from erofs.
[1] For additional details on the multi-app launch benchmarks, please
refer to commit 0f6273ab4637 ("erofs: add a reserved buffer pool for lz4
decompression").

The blk_add_partition() function initially used a single if-condition
(IS_ERR(part)) to check for errors when adding a partition. This was
modified to handle the specific case of -ENXIO separately, allowing the
function to proceed without logging the error in this case. However,
this change unintentionally left a path where md_autodetect_dev()
could be called without confirming that part is a valid pointer.
This commit separates the error handling logic by splitting the
initial if-condition, improving code readability and handling specific
error scenarios explicitly. The function now distinguishes the general
error case from -ENXIO without altering the existing behavior of
md_autodetect_dev() calls.

There is a real deadlock as well as sleeping in atomic() bug in here, if
the bo put happens to be the last ref, since bo destruction wants to
grab the same spinlock and sleeping locks. Fix that by dropping the ref
using xe_bo_put_deferred(), and moving the final commit outside of the
lock. Dropping the lock around the put is tricky since the bo can go
out of scope and delete itself from the list, making it difficult to
navigate to the next list entry.

nf_flow_table_module_init()

routine since nf_flow_table_bpf is part of nf_flow_table module and not
nf_flow_table_inet one. This patch allows to avoid the following kernel
warning running the reproducer below:

Export kernel paravirt features to user space, so that VMM can control
each single paravirt feature. By default paravirt features will be the
same with kvm supported features if VMM does not set it.
Also a new feature KVM_FEATURE_VIRT_EXTIOI is added which can be set
from user space. This feature indicates that the virt EIOINTC can route
interrupts to 256 vCPUs, rather than 4 vCPUs like with real HW.

On LoongArch, the host and guest have their own PMU CSRs registers and
they share PMU hardware resources. A set of PMU CSRs consists of a CTRL
register and a CNTR register. We can set which PMU CSRs are used by the
guest by writing to the GCFG register [24:26] bits.
On KVM side:
- Save the host PMU CSRs into structure kvm_context.
- If the host supports the PMU feature.
- When entering guest mode, save the host PMU CSRs and restore the guest PMU CSRs.
- When exiting guest mode, save the guest PMU CSRs and restore the host PMU CSRs.
