For NICs with a large (1024+) number of queues, this test can cause
excessive memory fragmentation. This results in OOM errors, and in the
worst case driver/kernel crashes. We don't need to test with the max number
of queues, just enough to create a high likelihood of races between
reconfiguration and stats getting read.

vfio_dma_mapping_test and vfio_pci_driver_test currently use iova=vaddr
as part of DMA mapping operations. However, not all IOMMUs support the
same virtual address width as the processor. For instance, older Intel
consumer platforms only support 39-bits of IOMMU address space. On such
platforms, using the virtual address as the IOVA fails.
Make the tests more robust by using iova_allocator to vend IOVAs, which
queries legally accessible IOVAs from the underlying IOMMUFD or VFIO
container.

VFIO selftests need to map IOVAs from legally accessible ranges, which
could vary between hardware. Tests in vfio_dma_mapping_test.c are making
excessively strong assumptions about which IOVAs can be mapped.
Add vfio_iommu_iova_ranges(), which queries IOVA ranges from the
IOMMUFD or VFIO container associated with the device. The queried ranges
are normalized to IOMMUFD's iommu_iova_range representation so that
handling of IOVA ranges up the stack can be implementation-agnostic.
iommu_iova_range and vfio_iova_range are equivalent, so bias to using the
new interface's struct.
Query IOMMUFD's ranges with IOMMU_IOAS_IOVA_RANGES.
Query VFIO container's ranges with VFIO_IOMMU_GET_INFO and
VFIO_IOMMU_TYPE1_INFO_CAP_IOVA_RANGE.
The underlying vfio_iommu_type1_info buffer-related functionality has
been kept generic so the same helpers can be used to query other
capability chain information, if needed.

Reduce the time waiting for the QEMU pidfile from three minutes to five
seconds. The three minute time window was chosen to make sure QEMU had
enough time to fully boot up. This, however, is an unreasonably long
delay for QEMU to write the pidfile, which happens earlier when the QEMU
process starts (not after VM boot). The three minute delay becomes
noticeably wasteful in future tests that expect QEMU to fail and wait a
full three minutes for a pidfile that will never exist.

Change QEMU to use generated pidfile names instead of just a single
globally-defined pidfile. This allows multiple QEMU instances to
co-exist with different pidfiles. This is required for future tests that
use multiple VMs to check for CID collissions.
Additionally, this also places the burden of killing the QEMU process
and cleaning up the pidfile on the caller of vm_start(). To help with
this, a function terminate_pidfiles() is introduced that callers use to
perform the cleanup. The terminate_pidfiles() function supports multiple
pidfile removals because future patches will need to process two
pidfiles at a time.
Change QEMU_OPTS to be initialized inside the vm_start(). This allows
the generated pidfile to be passed to the string assignment, and
prepares for future vm-specific options as well (e.g., cid).

awk doesn't gracefully handle SIGPIPE with a non-zero exit code, so grep
exiting upon finding a match causes false-positives when the pipefail

Improve usability of logging functions. Remove the test name prefix from
logging functions so that logging calls can be made deeper into the call
stack without passing down the test name or setting some global. Teach
log function to accept a LOG_PREFIX variable to avoid unnecessary
argument shifting.
Remove log_setup() and instead use log_host(). The host/guest prefixes
are useful to show whether a failure happened on the guest or host side,
but "setup" doesn't really give additional useful information. Since all
log_setup() calls happen on the host, lets just use log_host() instead.

MPTCP Join "fastclose server" selftest is sometimes failing because the
client output file doesn't have the expected size, e.g. 296B instead of
1024B.
When looking at a packet trace when this happens, the server sent the
expected 1024B in two parts -- 100B, then 924B -- then the MP_FASTCLOSE.
It is then strange to see the client only receiving 296B, which would
mean it only got a part of the second packet. The problem is then not on
the networking side, but rather on the data reception side.
When mptcp_connect is launched with '-f -1', it means the connection
might stop before having sent everything, because a reset has been
received. When this happens, the program was directly stopped. But it is
also possible there are still some data to read, simply because the
previous 'read' step was done with a buffer smaller than the pending
data, see do_rnd_read(). In this case, it is important to read what's
left in the kernel buffers before stopping without error like before.
SIGPIPE is now ignored, not to quit the app before having read
everything.

Create a netconsole test that puts a lot of pressure on the netconsole
list manipulation. Do it by creating dynamic targets and deleting
targets while messages are being sent. Also put interface down while the
messages are being sent, as creating parallel targets.
The code launches three background jobs on distinct schedules:
* Toggle netcons target every 30 iterations
* create and delete random_target every 50 iterations
* toggle iface every 70 iterations
This creates multiple concurrency sources that interact with netconsole
states. This is good practice to simulate stress, and exercise netpoll
and netconsole locks.
This test already found an issue as reported in [1]

The tracing selftest "event-filter-function.tc" was failing because it
first runs the "sample_events" function that triggers the kmem_cache_free
event and it looks at what function was used during a call to "ls".
But the first time it calls this, it could trigger events that are used to
pull pages into the page cache.
The rest of the test uses the function it finds during that call to see if
it will be called in subsequent "sample_events" calls. But if there's no
need to pull pages into the page cache, it will not trigger that function
and the test will fail.
Call the "sample_events" twice to trigger all the page cache work before
it calls it to find a function to use in subsequent checks.

It seems that most of the tests prepare the interfaces once before the test
run (setup_prepare()), rely on setup_wait() to wait for link and only then
run the test(s).
local_termination brings the physical interfaces down and up during test
run but never wait for them to come up. If the auto-negotiation takes
some seconds, first test packets are being lost, which leads to
false-negative test results.
Use setup_wait() in run_test() to make sure auto-negotiation has been
completed after all simple_if_init() calls on physical interfaces and test
packets will not be lost because of the race against link establishment.

- Revert "wifi: ath10k: avoid unnecessary wait for service ready
message" caused regressions for QCA988x and QCA9984
- Revert "wifi: ath12k: Fix missing station power save configuration"
caused regressions for WCN7850
- eth: bnxt_en: shutdown FW DMA in bnxt_shutdown(), fix memory
corruptions after kexec
Previous releases - always broken:
- virtio-net: fix received packet length check for big packets
- sctp: fix races in socket diag handling
- wifi: add an hrtimer-based delayed work item to avoid low
granularity of timers set relatively far in the future, and use it
where it matters (e.g. when performing AP-scheduled channel switch)
- eth: mlx5e:
- correctly propagate error in case of module EEPROM read failure
- fix HW-GRO on systems with PAGE_SIZE == 64kB
- dsa: b53: fixes for tagging, link configuration / RMII, FDB,
multicast
- phy: lan8842: implement latest errata"

Sometimes VMs will have some intermittent dmesg warnings that are
unrelated to vsock. Change the dmesg parsing to filter on strings
containing 'vsock' to avoid false positive failures that are unrelated
to vsock. The downside is that it is possible for some vsock related
warnings to not contain the substring 'vsock', so those will be missed.
Fixes: a4a65c6fe0 ("selftests/vsock: add initial vmtest.sh for vsock")

Adding test that attaches kprobe/kretprobe multi and verifies the
ORC stacktrace matches expected functions.
Adding bpf_testmod_stacktrace_test function to bpf_testmod kernel
module which is called through several functions so we get reliable
call path for stacktrace.
The test is only for ORC unwinder to keep it simple.

Update all struct proto_ops connect() callback function prototypes from
"struct sockaddr *" to "struct sockaddr_unsized *" to avoid lying to the
compiler about object sizes. Calls into struct proto handlers gain casts
that will be removed in the struct proto conversion patch.
No binary changes expected.
