This removes the concept of "subtypes", instead letting the tests use proper
VM types that were recently added. While the sev_init_vm() and sev_es_init_vm()
are still able to operate with the legacy KVM_SEV_INIT and KVM_SEV_ES_INIT
ioctls, this is limited to VMs that are created manually with
vm_create_barebones().

When looking at Alexei's patch ([1]) which added tests for atomics,
I noticed that the tests will be skipped with cpuv4. For example,
with latest llvm19, I see:
[root@arch-fb-vm1 bpf]# ./test_progs -t arena_atomics
#3/1 arena_atomics/add:OK
...
#3/7 arena_atomics/xchg:OK
#3 arena_atomics:OK
Summary: 1/7 PASSED, 0 SKIPPED, 0 FAILED
[root@arch-fb-vm1 bpf]# ./test_progs-cpuv4 -t arena_atomics
#3 arena_atomics:SKIP
Summary: 1/0 PASSED, 1 SKIPPED, 0 FAILED
[root@arch-fb-vm1 bpf]#
It is perfectly fine to enable atomics-related tests for cpuv4.
With this patch, I have
[root@arch-fb-vm1 bpf]# ./test_progs-cpuv4 -t arena_atomics

After commit 40867d74c374 ("net: Add l3mdev index to flow struct and
avoid oif reset for port devices") it is possible to configure FIB rules
that match on iif / oif being a l3mdev port. It was not possible before
as these parameters were reset to the ifindex of the l3mdev device
itself prior to the FIB rules lookup.
Add tests that cover this functionality as it does not seem to be
covered by existing ones and I am aware of at least one user that needs
this functionality in addition to the one mentioned in [1].
Reuse the existing FIB rules tests by simply configuring a VRF prior to
the test and removing it afterwards. Differentiate the output of the
non-VRF tests from the VRF tests by appending "(VRF)" to the test name
if a l3mdev FIB rule is present.
Verified that these tests do fail on kernel 5.15.y which does not
include the previously mentioned commit:
# ./fib_rule_tests.sh -t fib_rule6_vrf
[...]
TEST: rule6 check: oif redirect to table (VRF) [FAIL]

The struct adjtimex freq field takes a signed value who's units are in
shifted (<<16) parts-per-million.
Unfortunately for negative adjustments, the straightforward use of:
freq = ppm << 16 trips undefined behavior warnings with clang:
valid-adjtimex.c:66:6: warning: shifting a negative signed value is undefined [-Wshift-negative-value]
-499<<16,
~~~~^
valid-adjtimex.c:67:6: warning: shifting a negative signed value is undefined [-Wshift-negative-value]
-450<<16,
~~~~^
..
Fix it by using a multiply by (1 << 16) instead of shifting negative values
in the valid-adjtimex test case. Align the values for better readability.

With multiple reader threads POLLing a single UFFD, the demand paging test
suffers from the thundering herd problem: performance degrades as the
number of reader threads is increased. Solve this issue [1] by switching
the the polling mechanism to EPOLL + EPOLLEXCLUSIVE.
Also, change the error-handling convention of uffd_handler_thread_fn.
Instead of just printing errors and returning early from the polling
loop, check for them via TEST_ASSERT(). "return NULL" is reserved for a
successful exit from uffd_handler_thread_fn, i.e. one triggered by a
write to the exit pipe.
Performance samples generated by the command in [2] are given below.
Num Reader Threads, Paging Rate (POLL), Paging Rate (EPOLL)
1 249k 185k
2 201k 235k
4 186k 155k
16 150k 217k

paging test
At the moment, demand_paging_test does not support profiling/testing
multiple vCPU threads concurrently faulting on a single uffd because
(a) "-u" (run test in userfaultfd mode) creates a uffd for each vCPU's
region, so that each uffd services a single vCPU thread.
(b) "-u -o" (userfaultfd mode + overlapped vCPU memory accesses)
simply doesn't work: the test tries to register the same memory
to multiple uffds, causing an error.
Add support for many vcpus per uffd by
(1) Keeping "-u" behavior unchanged.
(2) Making "-u -a" create a single uffd for all of guest memory.
(3) Making "-u -o" implicitly pass "-a", solving the problem in (b).
In cases (2) and (3) all vCPU threads fault on a single uffd.
With potentially multiple vCPUs per UFFD, it makes sense to allow
configuring the number of reader threads per UFFD as well: add the "-r"
flag to do so.

Using the overall demand paging rate to measure performance can be
slightly misleading when vCPU accesses are not overlapped. Adding more
vCPUs will (usually) increase the overall demand paging rate even
if performance remains constant or even degrades on a per-vcpu basis. As
such, it makes sense to report both the total and per-vcpu paging rates.

check_timer_distribution() runs ten threads in a busy loop and tries to
test that the kernel distributes a process posix CPU timer signal to every
thread over time.
There is not guarantee that this is true even after commit bcb7ee79029d
("posix-timers: Prefer delivery of signals to the current thread") because
that commit only avoids waking up the sleeping process leader thread, but
that has nothing to do with the actual signal delivery.
As the signal is process wide the first thread which observes sigpending
and wins the race to lock sighand will deliver the signal. Testing shows
that this hangs on a regular base because some threads never win the race.
The comment "This primarily tests that the kernel does not favour any one."
is wrong. The kernel does favour a thread which hits the timer interrupt
when CLOCK_PROCESS_CPUTIME_ID expires.
Rewrite the test so it only checks that the group leader sleeping in join()
never receives SIGALRM and the thread which burns CPU cycles receives all
signals.
In older kernels which do not have commit bcb7ee79029d ("posix-timers:
Prefer delivery of signals to the current thread") the test-case fails
immediately, the very 1st tick wakes the leader up. Otherwise it quickly
succeeds after 100 ticks.
CI testing wants to use newer selftest versions on stable kernels. In this
case the test is guaranteed to fail.
So check in the failure case whether the kernel version is less than v6.3
and skip the test result in that case.

max_guest_memory_test uses ucalls to sync with the host, but
it also resets the guest RIP back to its initial value in between
tests stages.
This makes the guest never reach the code which frees the ucall struct
and since a fixed pool of 512 ucall structs is used, the test starts
to fail when more that 256 vCPUs are used.
Fix that by replacing the manual register reset with a loop in

'delay 1' in tc-netem is confusing, not sure if it's a delay of 1 second or
1 millisecond. This patch explicitly adds millisecond units to make these
commands clearer.

tc are used in some test scripts: mptcp_connect.sh, mptcp_join.sh and
simult_flows.sh. It makes sense to check if tc is installed before running
these scripts, just like other tools. So this patch add 'tc' check for
mptcp_lib_check_tools(), and check it in these test scripts.

Add a very simple test to make sure drivers report expected
stats. Drivers which implement FEC or pause configuration
should report relevant stats. Qstats must be reported,
at least packet and byte counts, and they must match
total device stats.
Tested with netdevsim, bnxt, in-tree and installed.

Add drivers/net as a target for mixed-use tests.
The setup is expected to work similarly to the forwarding tests.
Since we only need one interface (unlike forwarding tests)
read the target device name from NETIF. If not present we'll
try to run the test against netdevsim.
