This test triggers a TM Bad Thing by raising a signal in transactional state
and forcing a pagefault to happen in kernelspace when the kernel signal
handling code first touches the user signal stack.
This is inspired by the test tm-signal-context-force-tm but uses userfaultfd to
make the test deterministic. While this test always triggers the bug in one
run, I had to execute tm-signal-context-force-tm several times (the test runs
5000 times each execution) to trigger the same bug.
tm-signal-context-force-tm is kept instead of replaced because, while this test
is more reliable and triggers the same bug, tm-signal-context-force-tm has a
better coverage, in the sense that by running the test several times it might
trigger the pagefault and/or be preempted at different places.
v3: skip test if userfaultfd is unavailable.

There's two different paths through the sigreturn code, depending on
whether the VDSO is mapped or not. We recently discovered a bug in the
unmapped case, because it's not commonly used these days.
So add a test that sends itself a signal, then moves the VDSO, takes
another signal and finally unmaps the VDSO before sending itself
another signal. That tests the standard signal path, the code that
handles the VDSO being moved, and also the signal path in the case
where the VDSO is unmapped.

The ftrace selftest "ftrace - test for function traceon/off triggers"
enables all events and reads the trace file. Now that the trace file does
not disable tracing, and will attempt to continually read new data that is
added, the selftest gets stuck reading the trace file. This is because the
data added to the trace file will fill up quicker than the reading of it.
By only enabling scheduling events, the read can keep up with the writes.
Instead of enabling all events, only enable the scheduler events.

We precompute the static-static ECDH during configuration time, in order
to save an expensive computation later when receiving network packets.
However, not all ECDH computations yield a contributory result. Prior,
we were just not letting those peers be added to the interface. However,
this creates a strange inconsistency, since it was still possible to add
other weird points, like a valid public key plus a low-order point, and,
like points that result in zeros, a handshake would not complete. In
order to make the behavior more uniform and less surprising, simply
allow all peers to be added. Then, we'll error out later when doing the
crypto if there's an issue. This also adds more separation between the
crypto layer and the configuration layer.

Previously we could get the report of branch type statistics.

# Branch Statistics:

COND_BWD: 4.1%

COND: 44.7%
UNCOND: 0.0%
IND: 6.1%
CALL: 24.5%
RET: 24.7%
But now for the recent perf, it can't report the branch type statistics.
It's a regression issue caused by commit 40c39e3046 ("perf report: Fix
a no annotate browser displayed issue"), which only counts the branch
type statistics for browser mode.
This patch moves the branch_type_count() outside of ui__has_annotation()
checking, then branch type statistics can work for stdio mode.

Previous attempt to make tcp_rtt more robust introduced a new race, in which
server_done might be set to true before server can actually accept any
connection. Fix this by unconditionally waiting for accept(). Given socket is
non-blocking, if there are any problems with client side, it should eventually
close listening FD and let server thread exit with failure.

Amazingly, some libc implementations don't call __NR_nanosleep syscall from
their nanosleep() APIs. Hammer it down with explicit syscall() call and never
get back to it again. Also simplify code for timespec initialization.
I verified that nanosleep is called w/ printk and in exactly same Linux image
that is used in Travis CI. So it should both sleep and call correct syscall.
v1->v2:
- math is too hard, fix usec -> nsec convertion (Martin);
- test_vmlinux has explicit nanosleep() call, convert that one as well.

KVM: s390: Features and Enhancements for 5.7 part1
1. Allow to disable gisa
2. protected virtual machines
Protected VMs (PVM) are KVM VMs, where KVM can't access the VM's
state like guest memory and guest registers anymore. Instead the
PVMs are mostly managed by a new entity called Ultravisor (UV),
which provides an API, so KVM and the PV can request management
actions.
PVMs are encrypted at rest and protected from hypervisor access
while running. They switch from a normal operation into protected
mode, so we can still use the standard boot process to load a
encrypted blob and then move it into protected mode.
Rebooting is only possible by passing through the unprotected/normal
mode and switching to protected again.
One mm related patch will go via Andrews mm tree ( mm/gup/writeback:
add callbacks for inaccessible pages)
Check that guest doesn't hang when an invalid eVMCS GPA is specified.

indicate a failure and stop execution.
This change introduces the TEST_FAIL macro which is a wrap around
TEST_ASSERT(false, ...) and so provides a direct alternative for
failing a test.

Normal reset and initial CPU reset do not clear all registers. Add a
test that those registers are NOT changed.

We should not only test the oneregs or the get_(x)regs interfaces but
also the sync_regs. Those are usually the canonical place for register
content.

The guest crashes very early due to changes in the control registers
used by dynamic address translation. Let us use different registers
that will not crash the guest.

The steal-time test confirms what is reported to the guest as stolen
time is consistent with the run_delay reported for the VCPU thread
on the host. Both x86_64 and AArch64 have the concept of steal/stolen
time so this test is introduced for both architectures.
While adding the test we ensure .gitignore has all tests listed
(it was missing s390x/resets) and that the Makefile has all tests
listed in alphabetical order (not really necessary, but it almost
was already...). We also extend the common API with a new num-guest-
pages call and a new timespec call.

Also correct the comment and prototype for vm_create_default(),

s390 requires 1M aligned guest sizes. Embedding the rounding in
vm_adjust_num_guest_pages() allows us to remove it from a few
other places.
