Several KUnit tests can only be built into the kernel image, and the
shipped kernel builds its tests as modules, so nothing runs them. The
series adds a "um" config variant: a User Mode Linux kernel with every
KUnit test built in, under KASAN and UBSAN. kernel.spec builds it with
ARCH=um, kernel-selftests-internal ships it, and the hci-kunit test runs
it.

The variant inherits the generic and generic-x86 layers, so the tests
meet the options of the shipped x86_64 kernel, vz ones included. What
differs lives in custom-overrides/generic/um, one file per option as
for the other variants, and passes process_configs.sh -n -w -c.

- 1/4: the um variant, with the reason for each option turned off
- 2/4: KASAN_KUNIT_TEST keeps its prompt under KUNIT_ALL_TESTS, so
  that the um config can leave it out
- 3/4: KASAN, without its self-test
- 4/4: no debug info, which kernel.spec would throw away anyway

Outside this series:

- vzkernel.vzspecs: "kernel.spec: build the User Mode Linux KUnit
  kernel" builds and packages it from kernel-um-rhel.config
- git-publish.sh brings kernel-um-rhel.config to vzkernel.vzspecs
  along with the x86_64 configs
- hci-tests PR #9241 (hci-kunit) runs it; a follow-up boots it with
  kasan_multi_shot

The overrides and their reasons come from Eva Kurchatova's
kunit-uml-config.sh approach in vzkernel.vzspecs, which derived the
config at build time. This series moves the config into the kernel
tree.

Several KUnit tests can only be built into the kernel image, and the
shipped kernel builds its tests as modules. Add the "um" variant,
kernel-um-rhel.config: a User Mode Linux kernel with every KUnit test
built in, which kernel.spec builds with ARCH=um.

The variant inherits the generic and generic-x86 layers, so the tests
meet the options of the shipped x86_64 kernel, vz ones included.
custom-overrides/generic/um holds what has to differ:

- the User Mode Linux options, which no other layer sets
- KUNIT, KUNIT_ALL_TESTS and the KUnit tests built in, where the
  generic layers have them as modules, and what follows from that
- the subsystems tools/testing/kunit/configs/all_tests.config builds in
  for their tests
- UBSAN, DEBUG_VM, DEBUG_OBJECTS, DEBUG_SG and friends, so that a test
  which provokes a report is not silent

Turned off, each for a reason:

- WERROR: lib/iomap.c defines the 64-bit accessors on every 64-bit
  build, asm-generic/iomap.h declares them only where readq exists,
  and UML has none, so -Werror=missing-prototypes stops the build
- VT: its console takes the "tty" name first, and the test output
  goes to a dummy display instead of the runner
- SERIAL_8250: it probes the legacy ISA ports, which UML routes to
  logic_iomem, one warning per port
- UBSAN_ALIGNMENT: UML lacks HAVE_EFFICIENT_UNALIGNED_ACCESS, so it
  would report every deliberate unaligned access of the network stack
- LD_SCRIPT_DYN_RPATH: rpm's check-rpaths rejects the /lib and /lib64
  rpaths it adds

Lock debugging stays off, as in the shipped kernel: the drm suites are
not clean under it, and lockdep stops checking at its first report.

KASAN_KUNIT_TEST hides its prompt when KUNIT_ALL_TESTS is set, so a
config that builds every KUnit test in cannot leave this one out.

The User Mode Linux KUnit kernel needs to. The test provokes KASAN
reports on purpose and expects them on the console, and hci-kunit
fails a UML run on any report it finds in the output.

Show the prompt unconditionally. The default still follows
KUNIT_ALL_TESTS, so configs that do not set the option keep their
value.

Generic KASAN catches out-of-bounds and use-after-free accesses that a
test itself does not notice. Instrumentation is inline and covers
vmalloc too.

The KASAN self-test stays out. It makes bad accesses on purpose and
expects their reports on the console, where hci-kunit counts any report
as a failure of the run. What it checks is KASAN itself, not our code.

SLUB_DEBUG_ON stays off: KASAN catches what its redzones and poisoning
would, and at the moment of the access.

kernel.spec strips the UML binary and deletes the debug info it
extracts, as for the selftests. Every build generated DWARF and BTF for
the whole image only to throw them away.

Nothing that reads a run needs them:

- WARN and BUG reports carry file:line (DEBUG_BUGVERBOSE)
- UBSAN reports carry file:line of the check
- KASAN reports and stack traces name the functions through kallsyms

For line numbers in a KASAN stack, rebuild the same source with debug
info: the config is in the binary (IKCONFIG), and gcc generates the
same code with and without -g. BTF has no user at all, nothing runs
BPF in the UML kernel.

The config is faithful. I built kernel-um-rhel.config, and compared it 
with what kunit-uml-config.sh makes from the shipped x86_64 config: the 
same 77 KUnit tests built in, the same vz options, the same sanity 
checks. The only differences are the debug info (4/4) and the KASAN 
self-test (2/4, 3/4). Built with ARCH=um and booted with 
kasan_multi_shot: 182 pass, 0 fail, no kernel report.

Two points that I still believe are unresolved:


1. Please drop 2/4 and keep the KASAN self-test. hci-kunit does not fail 
on its reports: since "hci-kunit: leave the reports of a suite that 
provokes them out of the check" (PR #9241) reports inside the kasan 
suite are expected, and the run is 183 pass, 0 fail with it. The test is 
also the only proof that KASAN catches anything in this kernel. Without 
it, a KASAN that silently stopped working would look like a clean run. 
And 2/4 would be a vz-only change to lib/Kconfig.kasan that mainline 
does not need.

2. The static list of builtin tests will drift. 69 of the override files 
only turn a generic =m test into =y. A KUnit test that a RHEL import 
adds lands in common/generic as =m and stays a module here, which the 
UML kernel never loads, so it silently does not run. process_configs.sh 
does not catch it, =m is a valid value. The script built every KUnit 
test in by itself.

A check in kernel.spec after olddefconfig would cover it: fail when a 
symbol defaulting to KUNIT_ALL_TESTS is =m, except the tests whose 
subsystem is a module (cfg80211, mac80211, iwlwifi, xe, vkms, hid, 
rpcsec_gss_krb5, prp).

Optional: CONFIG_SLUB_RCU_DEBUG=y. It is a KASAN feature that catches 
use after free of RCU-freed slab objects, off here because the generic 
layer sets it off for kernels without KASAN. My config lacked it too, 
though.

Thank you for checking it and for running it.

There is no such commit in PR #9241. The branch still ends with
"hci-kunit: run the UML kernel for KUnit tests" of October 5, and
REPORT_MARKERS has no exception for any suite. Probably the filter has
not been pushed yet.

Even with the filter in place, I would rather not run the KASAN
self-test in the UML kernel:

- The filter is blind for as long as the kasan suite runs. A real
  report printed in that window, by deferred work of an earlier suite in
  a workqueue, an RCU callback or a timer, is dropped together with the
  expected ones.
- It depends on the KTAP framing and on the suite name, so the runner
  has to follow kasan_test from now on. A change there turns the run
  red rather than green, but it is still upkeep for no new coverage.
- The way KASAN can really disappear here is the config. kernel.spec
  runs olddefconfig with the real compiler, and a toolchain without
  KASAN support drops CONFIG_KASAN silently; process_configs.sh does not
  see it, as it runs with dummy-tools. The self-test does not catch that
  either: KASAN_KUNIT_TEST depends on KASAN, so the kasan suite just
  vanishes from a green run. A check of the final .config does catch
  it, see 2 below.
- At run time, the KASAN code is the upstream one. Neither mm/kasan nor
  the UML KASAN support carry vz changes, and upstream runs this very
  self-test on every release.

2/4 is a vz-only change indeed, a one-line one. I prefer it to a blind
spot in the runner.

Most of them do not drift. Nearly every KUnit test hides its prompt
behind "if !KUNIT_ALL_TESTS", so with KUNIT_ALL_TESTS=y Kconfig ignores
the =m of the generic layer and builds the test in by itself. Their =y
files are there only to keep process_configs.sh -c quiet, and a new test
of that kind is built in without anyone touching the um layer.

A test whose prompt stays visible does stay =m, as you say:
REGMAP_KUNIT, USERCOPY_KUNIT_TEST and the SND_*_TEST ones today. So yes,
let's have the check. The plan:

- A script next to the um layer in redhat/configs, which kernel.spec
  calls on the final .config, after olddefconfig and before the build.
- It fails the build when a symbol defaulting to KUNIT_ALL_TESTS is =m.
- It also fails when an option the variant exists for did not survive
  olddefconfig: KUNIT, KASAN, UBSAN and the other checks. That is the
  config check from 1.

No exception list. The tests you name cannot be turned off under
KUNIT_ALL_TESTS either, most of them hide their prompt the same way.
What keeps them =m is a subsystem we ship as a module only, so the um
layer turns that one off instead:

- CFG80211, mac80211 and iwlwifi go with it
- DRM_XE
- DRM_VKMS
- HID_UCLOGIC
- RPCSEC_GSS_KRB5
- HSR

A module the UML kernel never loads is of no use there. Their tests stay
with the modules mode of hci-kunit on the real kernel, except the xe one,
which our kernel does not build at all.

A new test of that kind then fails the build, and whoever fixes it
decides whether its subsystem goes off in UML or gets built in.

Agreed, cheap and useful. I'll add it to 3/4.

Updated the PR; The commits were squashed since, the filter is in 
"hci-kunit: run the UML kernel for KUnit tests".

Agreed, the blind window is there. Keep 2/4. I assume the filter in the 
hci-kunit PR goes away then?

I see. The tests that stay =m in v1 are exactly the module-only ones on 
your list, so turning those subsystems off and failing on any =m 
leftover covers it.


One note: the final .config does not say which symbols default to 
KUNIT_ALL_TESTS, so it needs that list from the Kconfig files (grepping 
"default KUNIT_ALL_TESTS" gives the 110).

Yes, please drop it. With 2/4, nothing in the UML run provokes a report
on purpose. Thanks for taking the kasan_multi_shot commit.

Right, 6/6 of v2 takes the list from the Kconfig files of the tree, and
fails rather than pass when it finds none.
