- Revert the fail-the-build-on-fatal-errors objtool strategy for now due to the
ever-increasing matrix of supported toolchains/plugins and them causing too
many such fatal errors currently.
- Do not add empty symbols to objdump's rbtree to accommodate clang removing
section symbols.

Fix a bad interaction between the scv handling and the fallback L1D flush, which
could lead to user register corruption. Only affects people using scv (~no one)
on machines with old firmware that are missing the L1D flush.
Two small selftest fixes.

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().

$
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:
Reproduced the bug, then, on a:
$ grep -m1 ^'model name' /proc/cpuinfo

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.

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

As of now it doesn't consider cgroups when collecting shadow stats and
metrics so counter values from different cgroups will be saved in a same
slot. This resulted in incorrect numbers when those cgroups have
different workloads.
For example, let's look at the scenario below: cgroups A and C runs same
workload which burns a cpu while cgroup B runs a light workload.
$ perf stat -a -e cycles,instructions --for-each-cgroup A,B,C sleep 1
Performance counter stats for 'system wide':
3,958,116,522 cycles A
6,722,650,929 instructions A # 2.53 insn per cycle
1,132,741 cycles B
571,743 instructions B # 0.00 insn per cycle
4,007,799,935 cycles C
6,793,181,523 instructions C # 2.56 insn per cycle
1.001050869 seconds time elapsed
When I run 'perf stat' with single workload, it usually shows IPC around
1.7. We can verify it (6,722,650,929.0 / 3,958,116,522 = 1.698) for cgroup A.
But in this case, since cgroups are ignored, cycles are averaged so it
used the lower value for IPC calculation and resulted in around 2.5.
avg cycle: (3958116522 + 1132741 + 4007799935) / 3 = 2655683066
IPC (A) : 6722650929 / 2655683066 = 2.531
IPC (B) : 571743 / 2655683066 = 0.0002
IPC (C) : 6793181523 / 2655683066 = 2.557
We can simply compare cgroup pointers in the evsel and it'll be NULL
when cgroups are not specified. With this patch, I can see correct
numbers like below:
$ perf stat -a -e cycles,instructions --for-each-cgroup A,B,C sleep 1
Performance counter stats for 'system wide':
4,171,051,687 cycles A
7,219,793,922 instructions A # 1.73 insn per cycle
1,051,189 cycles B
583,102 instructions B # 0.55 insn per cycle
4,171,124,710 cycles C
7,192,944,580 instructions C # 1.72 insn per cycle

To pass more info to the saved_value in the runtime_stat, add a new
struct runtime_stat_data. Currently it only has 'ctx' field but later
patch will add more.
Note that we intentionally pass 0 as ctx to clock-related events for
compatibility. It was already there in a few places. So move the code
into the saved_value_lookup() explicitly and add a comment.

Building with the Clang assembler shows the following warning:
arch/x86/kernel/ftrace_64.o: warning: objtool: missing symbol for insn at offset 0x16
The Clang assembler strips section symbols. That ends up giving
objtool's find_func_containing() much more test coverage than normal.
Turns out, find_func_containing() doesn't work so well for overlapping
symbols:
2: 000000000000000e 0 NOTYPE LOCAL DEFAULT 2 fgraph_trace
3: 000000000000000f 0 NOTYPE LOCAL DEFAULT 2 trace
4: 0000000000000000 165 FUNC GLOBAL DEFAULT 2 __fentry__
5: 000000000000000e 0 NOTYPE GLOBAL DEFAULT 2 ftrace_stub
The zero-length NOTYPE symbols are inside __fentry__(), confusing the
rbtree search for any __fentry__() offset coming after a NOTYPE.
Try to avoid this problem by not adding zero-length symbols to the
rbtree. They're rare and aren't needed in the rbtree anyway.
One caveat, this actually might not end up being the right fix.
Non-empty overlapping symbols, if they exist, could have the same
problem. But that would need bigger changes, let's see if we can get
away with the easy fix for now.

It was found in [1] that bpf_inode_storage_get helper did not check
the nullness of the passed owner ptr which caused an oops when
dereferenced. This change incorporates the example suggested in [1] into
the local storage selftest.
The test is updated to create a temporary directory instead of just
using a tempfile. In order to replicate the issue this copied rm binary
is renamed tiggering the inode_rename with a null pointer for the
new_inode. The logic to verify the setting and deletion of the inode
local storage of the old inode is also moved to this LSM hook.
The change also removes the copy_rm function and simply shells out
to copy files and recursively delete directories and consolidates the
logic of setting the initial inode storage to the bprm_committed_creds
hook and removes the file_open hook.

This kunit update for Linux 5.11-rc3 consists one fix to force the use
of the 'tty' console for UML. Given that kunit tool requires the console
output, explicitly stating the dependency makes sense than relying on
it being the default.
