Migrate to kselftest harness. Use a fixture test with enclave initialized
and de-initialized for each of the existing three tests, in other words:
1. One FIXTURE() for managing the enclave life-cycle.
2. Three TEST_F()'s, one for each test case.
Dump lines of /proc/self/maps matching "sgx" in FIXTURE_SETUP() as this
can be very useful debugging information later on.
Amended commit log:
This migration changes the output of this test. Instead of skipping
the tests if open /dev/sgx_enclave fails, it will run all the tests
and report failures on all of them.

Rename symbols for better clarity:
* 'eenter' might be confused for directly calling ENCLU[EENTER]. It does
not. It calls into the VDSO, which actually has the EENTER instruction.
* 'sgx_call_vdso' is *only* used for entering the enclave. It's not some
generic SGX call into the VDSO.

In almost all cases from test_verifier that have been changed in here, we've
had an unreachable path with a load from a register which has an invalid
address on purpose. This was basically to make sure that we never walk this
path and to have the verifier complain if it would otherwise. Change it to
match on the right error for unprivileged given we now test these paths
under speculative execution.
There's one case where we match on exact # of insns_processed. Due to the
extra path, this will of course mismatch on unprivileged. Thus, restrict the
test->insn_processed check to privileged-only.
In one other case, we result in a 'pointer comparison prohibited' error. This
is similarly due to verifying an 'invalid' branch where we end up with a value
pointer on one side of the comparison.

Oliver reported a use case where deleting a VRF device can hang
waiting for the refcnt to drop to 0. The root cause is that the dst
is allocated against the VRF device but cached on the loopback
device.
The use case (added to the selftests) has an implicit VRF crossing
due to the ordering of the FIB rules (lookup local is before the
l3mdev rule, but the problem occurs even if the FIB rules are
re-ordered with local after l3mdev because the VRF table does not
have a default route to terminate the lookup). The end result is
is that the FIB lookup returns the loopback device as the nexthop,
but the ingress device is in a VRF. The mismatch causes the dst
alloc against the VRF device but then cached on the loopback.
The fix is to bring the trick used for IPv6 (see ip6_rt_get_dev_rcu):
pick the dst alloc device based the fib lookup result but with checks
that the result has a nexthop device (e.g., not an unreachable or
prohibit entry).

Add the infrastructure needed to enable exception handling in aarch64
selftests. The exception handling defaults to an unhandled-exception
handler which aborts the test, just like x86. These handlers can be
overridden by calling vm_install_exception_handler(vector) or
vm_install_sync_handler(vector, ec). The unhandled exception reporting
from the guest is done using the ucall type introduced in a previous
commit, UCALL_UNHANDLED.
The exception handling code is inspired on kvm-unit-tests.

x86, the only arch implementing exception handling, reports unhandled
vectors using port IO at a specific port number. This replicates what
ucall already does.
Introduce a new ucall type, UCALL_UNHANDLED, for guests to report
unhandled exceptions. Then replace the x86 unhandled vector exception
reporting to use it instead of port IO. This new ucall type will be
used in the next commits by arm64 to report unhandled vectors as well.

The guest in sync_regs_test does raw ucalls by directly accessing the
ucall IO port. It makes these ucalls without setting %rdi to a `struct
ucall`, which is what a ucall uses to pass messages. The issue is that
if the host did a get_ucall (the receiver side), it would try to access
the `struct ucall` at %rdi=0 which would lead to an error ("No mapping
for vm virtual address, gva: 0x0").
This issue is currently benign as there is no get_ucall in
sync_regs_test; however, that will change in the next commit as it
changes the unhandled exception reporting mechanism to use ucalls. In
that case, every vcpu_run is followed by a get_ucall to check if the
guest is trying to report an unhandled exception.
Fix this in advance by setting %rdi to a UCALL_NONE struct ucall for the
sync_regs_test guest.
Tested with gcc-[8,9,10], and clang-[9,11].

Errors like below were produced from test_util.c when compiling the KVM

lib/test_util.c: In function 'vm_mem_backing_src_alias':

.flag = anon_flags,
^~~~~~~~~~
lib/test_util.c:177:12: note: (near initialization for 'aliases[0].flag')
The reason is that we are using non-const expressions to initialize the

"anon_flags" and "anon_huge_flags" into more stable macros.

In the commit referenced below, a check was added to devlink_lib that
asserts the existence of a devlink device referenced by $DEVLINK_DEV.
Unfortunately, several netdevsim tests point DEVLINK_DEV at a device that
does not exist at the time that devlink_lib is sourced. Thus these tests
spuriously fail.
Fix this by introducing an override. By setting DEVLINK_DEV to an empty
string, the user declares their intention to handle DEVLINK_DEV management
on their own.
In all netdevsim tests that use devlink_lib and set DEVLINK_DEV, set
instead an empty DEVLINK_DEV just before sourcing devlink_lib, and set it
to the correct value right afterwards.

To check how many routes are installed in hardware, the test runs "ip
route" and greps for "offload", which includes routes with state
"offload_failed".
Till now, this wrong check was not found because after one failure in
route insertion, the driver moved to "abort" mode, which means that user
cannot try to add more routes.
The previous patch removed the abort mechanism and now failed routes are
counted as offloaded.
Fix this by not considering routes with "offload_failed" flag as
offloaded.

Previously, if rst2man caught errors, then these would be ignored and
the output file would be written anyway. This would allow developers to
introduce regressions in the docs comments in the BPF headers.
Additionally, even if you instruct rst2man to fail out, it will still
write out to the destination target file, so if you ran the tests twice
in a row it would always pass. Use a temporary file for the initial run
to ensure that if rst2man fails out under "--strict" mode, subsequent
runs will not automatically pass.

Until commit 39fe2fc96694 ("selftests: kvm: make allocation of extra
memory take effect", 2021-05-27), parameter extra_mem_pages was used
only to calculate the page table size for all the memory chunks,
because real memory allocation happened with calls of
vm_userspace_mem_region_add() after vm_create_default().
Commit 39fe2fc96694 however changed the meaning of extra_mem_pages to
the size of memory slot 0. This makes the memory allocation more
flexible, but makes it harder to account for the number of
pages needed for the page tables. For example, memslot_perf_test
has a small amount of memory in slot 0 but a lot in other slots,
and adding that memory twice (both in slot 0 and with later
calls to vm_userspace_mem_region_add()) causes an error that
was fixed in commit 000ac4295339 ("selftests: kvm: fix overlapping
addresses in memslot_perf_test", 2021-05-29)
Since both uses are sensible, add a new parameter slot0_mem_pages
to vm_create_with_vcpus() and some comments to clarify the meaning of
slot0_mem_pages and extra_mem_pages. With this change,
memslot_perf_test can go back to passing the number of memory
pages as extra_mem_pages.

When calling strtok() to parse the option, the incorrect delimiters

an invalid option error.
Fix this by using delimiters argument "," instead of ":\t" for parsing

Some distros may enable strict rp_filter by default, which will prevent
vethc from receiving the packets with an unrouteable reverse path address.

This extends the existing setsockopt test case to also check for cmsg
timestamps.
mptcp_connect will abort/fail if the setockopt was passed but the
timestamp cmsg isn't present after successful recvmsg().

vm_create allocates memory and maps it close to GPA. This memory
is separate from what is allocated in subsequent calls to
vm_userspace_mem_region_add, so it is incorrect to pass the
test memory size to vm_create_default. Just pass a small
fixed amount of memory which can be used later for page table,
otherwise GPAs are already allocated at MEM_GPA and the
test aborts.
