The test is pretty basic, and exercises UFFDIO_POISON straightforwardly.
We register a region with userfaultfd, in missing fault mode. For each
fault, we either UFFDIO_COPY a zeroed page (odd pages) or UFFDIO_POISON
(even pages). We do this mix to test "something like a real use case",
where guest memory would be some mix of poisoned and non-poisoned pages.
We read each page in the region, and assert that the odd pages are zeroed
as expected, and the even pages yield a SIGBUS as expected.
Why UFFDIO_COPY instead of UFFDIO_ZEROPAGE? Because hugetlb doesn't
support UFFDIO_ZEROPAGE, and we don't want to have special case code.

Previously, we had "one fault handler to rule them all", which used
several branches to deal with all of the scenarios required by all of the
various tests.
In upcoming patches, I plan to add a new test, which has its own slightly
different fault handling logic. Instead of continuing to add cruft to the
existing fault handler, let's allow tests to define custom ones, separate
from other tests.

Add a function test_unmerge_zero_page() to test the functionality on
unsharing and counting ksm-placed zero pages and counting of this patch
series.
test_unmerge_zero_page() actually contains four subjct test objects:
(1) whether the count of ksm zero pages can update correctly after merging;
(2) whether the count of ksm zero pages can update correctly after
unmerging by madvise(...MADV_UNMERGEABLE);
(3) whether the count of ksm zero pages can update correctly after
unmerging by triggering write fault.
(4) whether ksm zero pages are really unmerged.

Add a test to verify that when a memcg hits its limit in zswap, it doesn't
trigger an unwanted writeback that would result in pages not owned by that
memcg to be sent to disk, even if zswap isn't full. This was fixed by
commit 0bdf0efa180a("zswap: do not shrink if cgroup may not zswap").

Add a cgroup selftest that verifies memcg charging in zswap. The original
issue was that kmem bypass was applied to pages swapped out to zswap by
kswapd, resulting in zswapped memory not being charged. It was fixed by

Patch series "selftests: cgroup: add zswap test program".
This series adds 2 zswap related selftests that verify known and fixed
issues. A new dedicated test program (test_zswap) is proposed since the
test cases are specific to zswap and hosts specific helpers.
The first patch adds the (empty) test program, while the other 2 add an
actual test function each.
This patch (of 3):
Add empty cgroup-zswap self test scaffold program, test functions to be
added in the next commits.

Add coverage to x86's set_sregs_test to verify KVM rejects vendor-agnostic
illegal CR0 values, i.e. CR0 values whose legality doesn't depend on the
current VMX mode. KVM historically has neglected to reject bad CR0s from
userspace, i.e. would happily accept a completely bogus CR0 via
KVM_SET_SREGS{2}.
Punt VMX specific subtests to future work, as they would require quite a
bit more effort, and KVM gets coverage for CR0 checks in general through
other means, e.g. KVM-Unit-Tests.

Expand the binary stats test to verify that a stats fd can be dup()'d
and read, to (very) roughly simulate userspace passing around the file.
Adding the dup() test is primarily an intermediate step towards verifying
that userspace can read VM/vCPU stats before _and_ after userspace closes
its copy of the VM fd; the dup() test itself is only mildly interesting.

Move the stats fd cleanup code into stats_test() and drop the
superfluous vm_stats_test() and vcpu_stats_test() helpers in order to
decouple creation of the stats file from consuming/testing the file
(deduping code is a bonus). This will make it easier to test various
edge cases related to stats, e.g. that userspace can dup() a stats fd,
that userspace can have multiple stats files for a singleVM/vCPU, etc.

To allow running rseq and KVM's rseq selftests as statically linked
binaries, initialize the various "trampoline" pointers to point directly
at the expect glibc symbols, and skip the dlysm() lookups if the rseq
size is non-zero, i.e. the binary is statically linked *and* the libc
registered its own rseq.
Define weak versions of the symbols so as not to break linking against
libc versions that don't support rseq in any capacity.
The KVM selftests in particular are often statically linked so that they
can be run on targets with very limited runtime environments, i.e. test
machines.

When looking for something else in LKFT reports [1], I noticed most of
the tests were skipped because the "teardown stage" did not complete

Pedro found out this is due to the fact CONFIG_NF_FLOW_TABLE is required

issues on LKFT side. CONFIG_NET_ACT_CT is now set to 'm' in the final

When looking for something else in LKFT reports [1], I noticed that the
TC selftest ended with a timeout error:
not ok 1 selftests: tc-testing: tdc.sh # TIMEOUT 45 seconds
The timeout had been introduced 3 years ago, see the Fixes commit below.
This timeout is only in place when executing the selftests via the
kselftests runner scripts. I guess this is not what most TC devs are
using and nobody noticed the issue before.
The new timeout is set to 15 minutes as suggested by Pedro [2]. It looks
like it is plenty more time than what it takes in "normal" conditions.

PERF_RECORD_EXIT
The intent of this test is to check we get a PERF_RECORD_EXIT as asked
for by setting perf_event_attr.task=1.
When the test was written we didn't had the "dummy" event so we went
with the default event, "cycles".
There were reports of this test failing sometimes, one of these reports
was with a PREEMPT_RT_FULL, but I noticed it failing sometimes with an
aarch64 Firefly board.
In the kernel the call to perf_event_task_output(), that generates the
PERF_RECORD_EXIT may fail when there is not enough memory in the ring
buffer, if the ring buffer is paused, etc.
So switch to using the "dummy" event to use the ring buffer just for
what the test was designed for, avoiding uneeded PERF_RECORD_SAMPLEs.

The build failure reported in [1] occurred because commit <9fc96c7c19df>
("selftests: error out if kernel header files are not yet built") added
a new "kernel_header_files" dependency to "all", and that triggered
another, pre-existing problem. Specifically, the arm64 selftests
override the emit_tests target, and that override improperly declares
itself to depend upon the "all" target.
This is a problem because the "emit_tests" target in lib.mk was not
intended to be overridden. emit_tests is a very simple, sequential build
target that was originally invoked from the "install" target, which in
turn, depends upon "all".
That approach worked for years. But with 9fc96c7c19df in place,
emit_tests failed, because it does not set up all of the elaborate
things that "install" does. And that caused the new
"kernel_header_files" target (which depends upon $(KBUILD_OUTPUT) being
correct) to fail.
Some detail: The "all" target is .PHONY. Therefore, each target that
depends on "all" will cause it to be invoked again, and because
dependencies are managed quite loosely in the selftests Makefiles, many
things will run, even "all" is invoked several times in immediate
succession. So this is not a "real" failure, as far as build steps go:
everything gets built, but "all" reports a problem when invoked a second
time from a bad environment.
To fix this, simply remove the unnecessary "all" dependency from the
overridden emit_tests target. The dependency is still effectively
honored, because again, invocation is via "install", which also depends
upon "all".
An alternative approach would be to harden the emit_tests target so that
it can depend upon "all", but that's a lot more complicated and hard to
get right, and doesn't seem worth it, especially given that emit_tests
should probably not be overridden at all.

The riscv selftests (which were modeled after the arm64 selftests) are
improperly declaring the "emit_tests" target to depend upon the "all"
target. This approach, when combined with commit 9fc96c7c19df
("selftests: error out if kernel header files are not yet built"), has
caused build failures [1] on arm64, and is likely to cause similar
failures for riscv.
To fix this, simply remove the unnecessary "all" dependency from the
emit_tests target. The dependency is still effectively honored, because
again, invocation is via "install", which also depends upon "all".

When run under run_vmtests.sh, test scripts were failing to run with
"permission denied" due to the scripts not being executable.
It is also annoying not to be able to directly invoke run_vmtests.sh,
which is solved by giving also it the execute permission.

For instance, see how those 'cmd' ioctl arguments get translated, now
ATTACH_VRING_WORKER, GET_VRING_WORKER and NEW_WORKER, will be as well:

To pick the changes in:
b848b26c6672c9b9 ("net: Kill MSG_SENDPAGE_NOTLAST")
5e2ff6704a275be0 ("scm: add SO_PASSPIDFD and SCM_PIDFD")
4fe38acdac8a71f7 ("net: Block MSG_SENDPAGE_* from being passed to sendmsg() by userspace")
b841b901c452d926 ("net: Declare MSG_SPLICE_PAGES internal sendmsg() flag")
That don't result in any changes in the tables generated from that
header.
But while updating I noticed we were not handling MSG_BATCH and MSG_ZEROCOPY in the
hard coded table for the msg flags table, add them.
This silences this perf build warning:
