This was a not-too-busy cycle for documentation; highlights include:
- The beginnings of a set of translations into Spanish, headed up by Carlos
Bilbao.
- More Chinese translations.
- A change to the Sphinx "alabaster" theme by default for HTML generation.
Unlike the previous default (Read the Docs), alabaster is shipped with
Sphinx by default, reducing the number of other dependencies that need to
be installed. It also (IMO) produces a cleaner and more readable result.
- The ability to render the documentation into the texinfo format
(something Sphinx could always do, we just never wired it up until now).
Plus the usual collection of typo fixes, build-warning fixes, and minor
updates.

Pull random number generator updates from Jason Donenfeld:
- Replace prandom_u32_max() and various open-coded variants of it,
there is now a new family of functions that uses fast rejection
sampling to choose properly uniformly random numbers within an
interval:
get_random_u32_below(ceil) - [0, ceil)
get_random_u32_above(floor) - (floor, U32_MAX]
get_random_u32_inclusive(floor, ceil) - [floor, ceil]
Coccinelle was used to convert all current users of
prandom_u32_max(), as well as many open-coded patterns, resulting in
improvements throughout the tree.
I'll have a "late" 6.1-rc1 pull for you that removes the now unused
prandom_u32_max() function, just in case any other trees add a new
use case of it that needs to converted. According to linux-next,
there may be two trivial cases of prandom_u32_max() reintroductions
that are fixable with a 's/.../.../'. So I'll have for you a final
conversion patch doing that alongside the removal patch during the
second week.
This is a treewide change that touches many files throughout.
- More consistent use of get_random_canary().
- Updates to comments, documentation, tests, headers, and
simplification in configuration.
- The arch_get_random*_early() abstraction was only used by arm64 and
wasn't entirely useful, so this has been replaced by code that works
in all relevant contexts.
- The kernel will use and manage random seeds in non-volatile EFI
variables, refreshing a variable with a fresh seed when the RNG is
initialized. The RNG GUID namespace is then hidden from efivarfs to
prevent accidental leakage.
These changes are split into random.c infrastructure code used in the
EFI subsystem, in this pull request, and related support inside of
EFISTUB, in Ard's EFI tree. These are co-dependent for full
functionality, but the order of merging doesn't matter.
- Part of the infrastructure added for the EFI support is also used for
an improvement to the way vsprintf initializes its siphash key,
replacing an sleep loop wart.
- The hardware RNG framework now always calls its correct random.c
input function, add_hwgenerator_randomness(), rather than sometimes
going through helpers better suited for other cases.
- The add_latent_entropy() function has long been called from the fork
handler, but is a no-op when the latent entropy gcc plugin isn't
used, which is fine for the purposes of latent entropy.
But it was missing out on the cycle counter that was also being mixed
in beside the latent entropy variable. So now, if the latent entropy
gcc plugin isn't enabled, add_latent_entropy() will expand to a call
to add_device_randomness(NULL, 0), which adds a cycle counter,
without the absent latent entropy variable.
- The RNG is now reseeded from a delayed worker, rather than on demand
when used. Always running from a worker allows it to make use of the
CPU RNG on platforms like S390x, whose instructions are too slow to
do so from interrupts. It also has the effect of adding in new inputs
more frequently with more regularity, amounting to a long term
transcript of random values. Plus, it helps a bit with the upcoming
vDSO implementation (which isn't yet ready for 6.2).
- The jitter entropy algorithm now tries to execute on many different
CPUs, round-robining, in hopes of hitting even more memory latencies
and other unpredictable effects. It also will mix in a cycle counter
when the entropy timer fires, in addition to being mixed in from the
main loop, to account more explicitly for fluctuations in that timer
firing. And the state it touches is now kept within the same cache
line, so that it's assured that the different execution contexts will
cause latencies.

Perf events updates for v6.2:
- Thoroughly rewrite the data structures that implement perf task context handling,
with the goal of fixing various quirks and unfeatures both in already merged,
and in upcoming proposed code.
The old data structure is the per task and per cpu perf_event_contexts:
task_struct::perf_events_ctxp[] <-> perf_event_context <-> perf_cpu_context
^ | ^ | ^
`---------------------------------' | `--> pmu ---'
v ^
perf_event ------'
In this new design this is replaced with a single task context and
a single CPU context, plus intermediate data-structures:
task_struct::perf_event_ctxp -> perf_event_context <- perf_cpu_context
^ | ^ ^
`---------------------------' | |
| | perf_cpu_pmu_context <--.

Pull cxl updates from Dan Williams:
"Compute Express Link (CXL) updates for 6.2.
While it may seem backwards, the CXL update this time around includes
some focus on CXL 1.x enabling where the work to date had been with
CXL 2.0 (VH topologies) in mind.
First generation CXL can mostly be supported via BIOS, similar to DDR,
however it became clear there are use cases for OS native CXL error
handling and some CXL 3.0 endpoint features can be deployed on CXL 1.x
hosts (Restricted CXL Host (RCH) topologies). So, this update brings
RCH topologies into the Linux CXL device model.
In support of the ongoing CXL 2.0+ enabling two new core kernel
facilities are added.
One is the ability for the kernel to flag collisions between userspace
access to PCI configuration registers and kernel accesses. This is
brought on by the PCIe Data-Object-Exchange (DOE) facility, a hardware
mailbox over config-cycles.
The other is a cpu_cache_invalidate_memregion() API that maps to
wbinvd_on_all_cpus() on x86. To prevent abuse it is disabled in guest
VMs and architectures that do not support it yet. The CXL paths that
need it, dynamic memory region creation and security commands (erase /
unlock), are disabled when it is not present.
As for the CXL 2.0+ this cycle the subsystem gains support Persistent
Memory Security commands, error handling in response to PCIe AER
notifications, and support for the "XOR" host bridge interleave
algorithm.
Summary:
- Add the cpu_cache_invalidate_memregion() API for cache flushing in
response to physical memory reconfiguration, or memory-side data
invalidation from operations like secure erase or memory-device
unlock.
- Add a facility for the kernel to warn about collisions between
kernel and userspace access to PCI configuration registers
- Add support for Restricted CXL Host (RCH) topologies (formerly CXL
1.1)

- Add support for CXL Persistent Memory Security commands
- Add support for the "XOR" algorithm for CXL host bridge interleave

Documentation: dev-tools: Clarify requirements for result description
Currently the KTAP specification says that a test result line is <result> <number> [<description>][ # [<directive>] [<diagnostic data>]] and the description of a test can be "any sequence of words (can't include #)" which specifies that there may be more than one word but does not specify anything other than those words which might be used to separate the words which probably isn't what we want. Given that practically we have tests using a range of separators for words including combinations of spaces and combinations of other symbols like underscores or punctuation let's just clarify that the description can contain any character other than # (marking the start of the directive/diagnostic) or newline (marking the end of this test result).

apparmor: test: make static symbols visible during kunit testing
Use macros, VISIBLE_IF_KUNIT and EXPORT_SYMBOL_IF_KUNIT, to allow static symbols to be conditionally set to be visible during apparmor_policy_unpack_test, which removes the need to include the testing file in the implementation file. Change the namespace of the symbols that are now conditionally visible (by adding the prefix aa_) to avoid confusion with symbols of the same name. Allow the test to be built as a module and namespace the module name from policy_unpack_test to apparmor_policy_unpack_test to improve clarity of the module name. Provide an example of how static symbols can be dealt with in testing.

Create two macros: VISIBLE_IF_KUNIT - A macro that sets symbols to be static if CONFIG_KUNIT is not enabled. Otherwise if CONFIG_KUNIT is enabled there is no change to the symbol definition. EXPORT_SYMBOL_IF_KUNIT(symbol) - Exports symbol into EXPORTED_FOR_KUNIT_TESTING namespace only if CONFIG_KUNIT is enabled.

kunit: tool: make parser preserve whitespace when printing test log
Currently, kunit_parser.py is stripping all leading whitespace to make parsing easier. But this means we can't accurately show kernel output for failing tests or when the kernel crashes. Embarassingly, this affects even KUnit's own output, e.g. [13:40:46] Expected 2 + 1 == 2, but [13:40:46] 2 + 1 == 3 (0x3) [13:40:46] not ok 1 example_simple_test [13:40:46] [FAILED] example_simple_test After this change, here's what the output in context would look like [13:40:46] =================== example (4 subtests) =================== [13:40:46] # example_simple_test: initializing [13:40:46] # example_simple_test: EXPECTATION FAILED at lib/kunit/kunit-example-test.c:29 [13:40:46] Expected 2 + 1 == 2, but [13:40:46] 2 + 1 == 3 (0x3) [13:40:46] [FAILED] example_simple_test [13:40:46] [SKIPPED] example_skip_test [13:40:46] [SKIPPED] example_mark_skipped_test [13:40:46] [PASSED] example_all_expect_macros_test [13:40:46] # example: initializing suite [13:40:46] # example: pass:1 fail:1 skip:2 total:4 [13:40:46] # Totals: pass:1 fail:1 skip:2 total:4 [13:40:46] ===================== [FAILED] example ===================== This example shows one minor cosmetic defect this approach has.

Documentation: kunit: Fix "How Do I Use This" / "Next Steps" sections
The "How Do I Use This" section of index.rst and "Next Steps" section of
start.rst were just copies of the table of contents, and therefore
weren't really useful either when looking a sphinx generated output
(which already had the TOC visible) or when reading the source (where
it's just a list of files that ls could give you).
Instead, provide a small number of concrete next steps, and a bit more
description about what the pages contain.
This also removes the broken reference to 'tips.rst', which was
previously removed.

kunit: improve KTAP compliance of KUnit test output
Change KUnit test output to better comply with KTAP v1 specifications found here: https://kernel.org/doc/html/latest/dev-tools/ktap.html. 1) Use "KTAP version 1" instead of "TAP version 14" as test output header 2) Remove '-' between test number and test name on test result lines 2) Add KTAP version lines to each subtest header as well Note that the new KUnit output still includes the “# Subtest” line now located after the KTAP version line. This does not completely match the KTAP v1 spec but since it is classified as a diagnostic line, it is not expected to be disruptive or break any existing parsers.

kunit: tool: parse KTAP compliant test output
Change the KUnit parser to be able to parse test output that complies with the KTAP version 1 specification format found here: https://kernel.org/doc/html/latest/dev-tools/ktap.html. Ensure the parser is able to parse tests with the original KUnit test output format as well. KUnit parser now accepts any of the following test output formats: Original KUnit test output format: TAP version 14 1..1 # Subtest: kunit-test-suite 1..3 ok 1 - kunit_test_1 ok 2 - kunit_test_2 ok 3 - kunit_test_3 # kunit-test-suite: pass:3 fail:0 skip:0 total:3 # Totals: pass:3 fail:0 skip:0 total:3 ok 1 - kunit-test-suite KTAP version 1 test output format: KTAP version 1 1..1 KTAP version 1 1..3 ok 1 kunit_test_1 ok 2 kunit_test_2 ok 3 kunit_test_3 ok 1 kunit-test-suite New KUnit test output format (changes made in the next patch of this series): KTAP version 1 1..1 KTAP version 1 # Subtest: kunit-test-suite 1..3 ok 1 kunit_test_1 ok 2 kunit_test_2 ok 3 kunit_test_3 # kunit-test-suite: pass:3 fail:0 skip:0 total:3 # Totals: pass:3 fail:0 skip:0 total:3 ok 1 kunit-test-suite Signed-off-by: Rae Moar <rmoar@google.com> Reviewed-by: Daniel Latypov <dlatypov@google.com> Reviewed-by: David Gow <davidgow@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org> |

mm: slub: test: Use the kunit_get_current_test() function
Use the newly-added function kunit_get_current_test() instead of accessing current->kunit_test directly. This function uses a static key to return more quickly when KUnit is enabled, but no tests are actively running. There should therefore be a negligible performance impact to enabling the slub KUnit tests. Other than the performance improvement, this should be a no-op.

kunit: Use the static key when retrieving the current test
In order to detect if a KUnit test is running, and to access its context, the 'kunit_test' member of the current task_struct is used. Usually, this is accessed directly or via the kunit_fail_current_task() function. In order to speed up the case where no test is running, add a wrapper, kunit_get_current_test(), which uses the static key to fail early. Equally, Speed up kunit_fail_current_test() by using the static key. This should make it convenient for code to call this unconditionally in fakes or error paths, without worrying that this will slow the code down significantly. If CONFIG_KUNIT=n (or m), this compiles away to nothing. If CONFIG_KUNIT=y, it will compile down to a NOP (on most architectures) if no KUnit test is currently running. Note that kunit_get_current_test() does not work if KUnit is built as a module. This mirrors the existing restriction on kunit_fail_current_test(). Note that the definition of kunit_fail_current_test() still wraps an empty, inline function if KUnit is not built-in. This is to ensure that the printf format string __attribute__ will still work. Also update the documentation to suggest users use the new kunit_get_current_test() function, update the example, and to describe the behaviour when KUnit is disabled better.

kunit: Provide a static key to check if KUnit is actively running tests
KUnit does a few expensive things when enabled. This hasn't been a problem because KUnit was only enabled on test kernels, but with a few people enabling (but not _using_) KUnit on production systems, we need a runtime way of handling this. Provide a 'kunit_running' static key (defaulting to false), which allows us to hide any KUnit code behind a static branch. This should reduce the performance impact (on other code) of having KUnit enabled to a single NOP when no tests are running. Note that, while it looks unintuitive, tests always run entirely within __kunit_test_suites_init(), so it's safe to decrement the static key at the end of this function, rather than in __kunit_test_suites_exit(), which is only there to clean up results in debugfs.

kunit: tool: make --json do nothing if --raw_ouput is set
When --raw_output is set (to any value), we don't actually parse the test results. So asking to print the test results as json doesn't make sense. We internally create a fake test with one passing subtest, so --json would actually print out something misleading. This patch: * Rewords the flag descriptions so hopefully this is more obvious. * Also updates --raw_output's description to note the default behavior is to print out only "KUnit" results (actually any KTAP results) * also renames and refactors some related logic for clarity (e.g. test_result => test, it's a kunit_parser.Test object). Notably, this patch does not make it an error to specify --json and --raw_output together. This is an edge case, but I know of at least one wrapper around kunit.py that always sets --json. You'd never be able to use --raw_output with that wrapper.

Did any KUnit tests run? ============================================================ Testing complete. Ran 0 tests: errors: 1 Note: we could try and generate a more verbose message like > Please check .kunit/test.log to see the raw kernel output. or the like, but we'd need to know what the build dir was to know where test.log actually lives.

kunit: eliminate KUNIT_INIT_*_ASSERT_STRUCT macros
These macros exist because passing an initializer list to other macros
is hard.
The goal of these macros is to generate a line like
struct $ASSERT_TYPE __assertion = $APPROPRIATE_INITIALIZER;
e.g.
struct kunit_unary_assertion __assertion = {
.condition = "foo()",
.expected_true = true
};
But the challenge is you can't pass `{.condition=..., .expect_true=...}`
as a macro argument, since the comma means you're actually passing two
arguments, `{.condition=...` and `.expect_true=....}`.
So we'd made custom macros for each different initializer-list shape.
But we can work around this with the following generic macro
#define KUNIT_INIT_ASSERT(initializers...) { initializers }
Note: this has the downside that we have to rename some macros arguments
to not conflict with the struct field names (e.g. `expected_true`).
It's a bit gross, but probably worth reducing the # of macros.
