Merge tag 'libnvdimm-fixes-5.11-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm fixes from Dan Williams:
"A fix for a crash scenario that has been present since the initial
merge, a minor regression in sysfs attribute visibility, and a fix for
some flexible array warnings.
The bulk of this pull is an update to the libnvdimm unit test
infrastructure to test non-ACPI platforms. Given there is zero
regression risk for test updates, and the tests enable validation of
bits headed towards the next merge window, I saw no reason to hold the
new tests back. Santosh originally submitted this before the v5.11
window opened.
Summary:
- Fix a crash when sysfs accesses race 'dimm' driver probe/remove.
- Fix a regression in 'resource' attribute visibility necessary for
mapping badblocks and other physical address interrogations.
- Fix some flexible array warnings
- Expand the unit test infrastructure for non-ACPI platforms"

Michael Kerrisk suggested that, from an API perspective, it is a bad
idea to share the PR_SYS_DISPATCH_ defines between the prctl operation
and the selector variable.
Therefore, define two new constants to be used by SUD's selector variable
and update the corresponding documentation and test cases.
While this changes the API syscall user dispatch has never been part of a
Linux release, it will show up for the first time in 5.11.

The original code put five u32 before a u64 expansion[10] array. Five is
odd, this will cause trouble in the extension of the structure by adding
new features. This patch moves to use u8 for reserved field to avoid
future alignment risk.
Meanwhile, it also clears the memory of struct map_benchmark in tools,
otherwise, if users use old version to run on newer kernel, the random
expansion value will cause side effect on newer kernel.

A config array is used to hold the dimms for each bus. These dimms are
registered with nvdimm, and new nvdimms are created on the buses.

Since this module is written to be platform agnostic, the module is made
part of the PAPR_FAMILY. ndctl identifies the family using the compatible
string inside of_node dir-entry.

The current test module cannot be used for testing platforms (make check)
that do not have support for NFIT. In order to get the ndctl tests working,
we need a module which can emulate NVDIMM devices without relying on
ACPI/NFIT.
The aim of this proposed module is to implement a similar functionality to
the existing module but without the ACPI dependencies.
This RFC series is split into reviewable and compilable chunks.
This patch adds a new driver and registers two nvdimm bus needed for ndctl
make check.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Thanks to a recent binutils change which doesn't generate unused
symbols, it's now possible for thunk_64.o be completely empty without
CONFIG_PREEMPTION: no text, no data, no symbols.
We could edit the Makefile to only build that file when
CONFIG_PREEMPTION is enabled, but that will likely create confusion
if/when the thunks end up getting used by some other code again.
Just ignore it and move on.

This is basically a revert of commit 644592d328 ("objtool: Fail the
kernel build on fatal errors").
That change turned out to be more trouble than it's worth. Failing the
build is an extreme measure which sometimes gets too much attention and
blocks CI build testing.
These fatal-type warnings aren't yet as rare as we'd hope, due to the
ever-increasing matrix of supported toolchains/plugins and their
fast-changing nature as of late.
Also, there are more people (and bots) looking for objtool warnings than
ever before, so even non-fatal warnings aren't likely to be ignored for
long.

Joakim reports that getting "perf stat" for multiple system PMU metrics
segfaults:
$ perf stat -a -I 1000 -M imx8mm_ddr_write.all,imx8mm_ddr_write.all
Segmentation fault
$
While the same works without issue for a single metric.
The logic in metricgroup__add_metric_sys_event_iter() is broken, in that
add_metric() @m argument should be NULL for each new metric. Fix by not
passing a holder for that, and rather make local in
metricgroup__add_metric_sys_event_iter().

Segmentation fault
$
In commit c2337d6719 ("perf metricgroup: Fix metrics using aliases
covering multiple PMUs"), the logic in find_evsel_group() when iter'ing
events was changed to not only select events in same group, but also for
aliased PMUs.
Checking whether events were for aliased PMUs was done by comparing the
event PMU name. This was not safe for duration_time event, which has no
associated PMU (and no PMU name), so fix by checking if the event PMU name
is set also.
Committer testing:

perf_evlist__set_sid_idx() updates perf_sample_id with the evlist map
index, CPU number and TID. It is passed indexes to the evsel's cpu and
thread maps, but references the evlist's maps instead. That results in
using incorrect CPU numbers on heterogeneous systems. Fix it by using
evsel maps.
The id index (PERF_RECORD_ID_INDEX) is used by AUX area tracing when in
sampling mode. Having an incorrect CPU number causes the trace data to
be attributed to the wrong CPU, and can result in decoder errors because
the trace data is then associated with the wrong process.
Committer notes:
Keep the class prefix convention in the function name, switching from
perf_evlist__set_sid_idx() to perf_evsel__set_sid_idx().

Newer binutils (>= 2.36) refuse to assemble lmw/stmw when building in
little endian mode. That breaks compilation of our alignment handler
test:
/tmp/cco4l14N.s: Assembler messages:
/tmp/cco4l14N.s:1440: Error: `lmw' invalid when little-endian
/tmp/cco4l14N.s:1814: Error: `stmw' invalid when little-endian
make[2]: *** [../../lib.mk:139: /output/kselftest/powerpc/alignment/alignment_handler] Error 1
These tests do pass on little endian machines, as the kernel will
still emulate those instructions even when running little
endian (which is arguably a kernel bug).
But we don't really need to test that case, so ifdef those
instructions out to get the alignment test building again.

Since main() does not return a value explicitly, the
return values from FAIL_IF() conditions are ignored
and the tests can still pass irrespective of failures.
This makes sure that we always explicitly return the
correct test exit status.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

LinuxSourceTree will unceremoniously crash if the user doesn't call
read_kunitconfig() first in a number of functions.
And currently every place we create an instance, the caller also calls
create_kunitconfig() and read_kunitconfig().
Move these instead into __init__() so they can't be forgotten and to
reduce copy-paste.
The https://github.com/google/pytype type-checker complained that
_config wasn't initialized. With this, kunit_tool now type checks
under both pytype and mypy.
Add an optional boolean that can be used to disable this for use cases
in the future where we might not need/want to load the config.

The code to handle aggregating statuses didn't check that the status
actually got set to some non-None value.
Default the value to SUCCESS instead of adding a bunch of `is None`
checks.
This sorta follows the precedent in commit 3fc48259d5 ("kunit: Don't
fail test suites if one of them is empty").
Also slightly simplify the code and add type annotations.

The authors of this tool were more familiar with a different
type-checker, https://github.com/google/pytype.
That's open source, but mypy seems more prevalent (and runs faster).
And unlike pytype, mypy doesn't try to infer types so it doesn't check
unanotated functions.
So annotate ~all functions in kunit tool to increase type-checking
coverage.
Note: per https://www.python.org/dev/peps/pep-0484/, `__init__()` should
be annotated as `-> None`.
Doing so makes mypy discover a number of new violations.
Exclude main() since we reuse `request` for the different types of
requests, which mypy isn't happy about.
This commit fixes all but one error, where `TestSuite.status` might be
None.

Various helper functions were misspelling "diagnostic" in their names.

* https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf:
MAINTAINERS: Update my email address
selftests/bpf: Add verifier test for PTR_TO_MEM spill
bpf: Support PTR_TO_MEM{,_OR_NULL} register spilling
bpf: Reject too big ctx_size_in for raw_tp test run
libbpf: Allow loading empty BTFs
bpf: Allow empty module BTFs
bpf: Don't leak memory in bpf getsockopt when optlen == 0
bpf: Update local storage test to check handling of null ptrs
bpf: Fix typo in bpf_inode_storage.c
bpf: Local storage helpers should check nullness of owner ptr passed

- Set the minimum GCC version to 5.1 for arm64 due to earlier compiler
bugs.
- Make atomic helpers __always_inline to avoid a section mismatch when
compiling with clang.
- Fix the CMA and crashkernel reservations to use ZONE_DMA (remove the
arm64_dma32_phys_limit variable, no longer needed with a dynamic
ZONE_DMA sizing in 5.11).
- Remove redundant IRQ flag tracing that was leaving lockdep
inconsistent with the hardware state.
- Revert perf events based hard lockup detector that was causing
smp_processor_id() to be called in preemptible context.
- Some trivial cleanups - spelling fix, renaming S_FRAME_SIZE to
PT_REGS_SIZE, function prototypes added.

When 'perf inject' reads a perf.data file from an older version of perf,
it writes event attributes into the output with the original size field,
but lays them out as if they had the size currently used. Readers see a
corrupt file. Update the size field to match the layout.

In some cases, the number of cpus (nr_cpus_online) is confused with the
maximum cpu number (nr_cpus_avail), which results in the error in the
example below:
Example on system with 8 cpus:
Before:
# echo 0 > /sys/devices/system/cpu/cpu2/online
# ./perf record --kcore -e intel_pt// taskset --cpu-list 7 uname
Linux
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.147 MB perf.data ]
# ./perf script --itrace=e
Requested CPU 7 too large. Consider raising MAX_NR_CPUS
0x25908 [0x8]: failed to process type: 68 [Invalid argument]
After:
# ./perf script --itrace=e
#
Fixes: 8c7274691f ("perf machine: Replace MAX_NR_CPUS with perf_env::nr_cpus_online")
Fixes: 7df4e36a47 ("perf session: Replace MAX_NR_CPUS with perf_env::nr_cpus_online")
