It's caused by the symbol __test_function being in the ".bss" section:
$ readelf -a ./perf | less

$ nm perf | grep __test_function
0000000000c68548 B __test_function
I guess most of the time we're just lucky the inline asm ended up in the
".text" section, so making it specific explicit with push and pop
section clauses.

[ Upstream commit 39c0a53b114d0317e5c4e76b631f41d133af5cb0 ]
perf_event.h has macros that define the field offsets in the data_src
bitmask in perf records. The SNOOPX and REMOTE offsets were both 37.
These are distinct fields, and the bitfield layout in perf_mem_data_src
confirms that SNOOPX should be at offset 38.
Committer notes:
This was extracted from a larger patch that also contained kernel
changes.

[ Upstream commit fa4505675e093e895b7ec49a76d44f6b5ad9602e ]
When stdout output from the selftests tool 'test_maps' gets redirected
into e.g file or pipe, then the output lines increase a lot (from 21
to 33949 lines). This is caused by the printf that happens before the
fork() call, and there are user-space buffered printf data that seems
to be duplicated into the forked process.
To fix this fflush() stdout before the fork loop in __run_parallel().

[ Upstream commit 3337bf41e0dd70b4064cdf60acdfcdc2d050066c ]
An extra count on ebb_state.stats.pmc_count[PMC_INDEX(pmc)] is being per-
formed when count_pmc() is used to reset PMCs on a few selftests. This
extra pmc_count can occasionally invalidate results, such as the ones from
cycles_test shown hereafter. The ebb_check_count() failed with an above
the upper limit error due to the extra value on ebb_state.stats.pmc_count.
Furthermore, this extra count is also indicated by extra PMC1 trace_log on
the output of the cycle test (as well as on pmc56_overflow_test):

Fix the memory leakage in debuginfo__find_trace_events() when the probe
point is not found in the debuginfo. If there is no probe point found in
the debuginfo, debuginfo__find_probes() will NOT return -ENOENT, but 0.
Thus the caller of debuginfo__find_probes() must check the tf.ntevs and
release the allocated memory for the array of struct probe_trace_event.
The current code releases the memory only if the debuginfo__find_probes()
hits an error but not checks tf.ntevs. In the result, the memory allocated
on *tevs are not released if tf.ntevs == 0.
This fixes the memory leakage by checking tf.ntevs == 0 in addition to
ret < 0.

When using a cross-compilation environment, such as OpenEmbedded,
the CC an CXX variables are set to something more than just a
command: there are arguments (such as --sysroot) that need to be
passed on to the compiler so that the right set of headers and
libraries are used.
For the particular case that our systems detected, CC is set to
the following:
export CC="aarch64-linaro-linux-gcc --sysroot=/oe/build/tmp/work/machine/perf/1.0-r9/recipe-sysroot"
Without quotes, detection is as follows:

For memcpy, the source pages are memset to zero only when --cycles is
used. This leads to wildly different results with or without --cycles,
since all sources pages are likely to be mapped to the same zero page
without explicit writes.

commit c8c188679c ("tools build: Use the same CC for feature detection
and actual build") changed these assignments from unconditional (:=) to
conditional (?=) so that they wouldn't clobber values from the
environment. However, conditional assignment does not work properly for
variables that Make implicitly sets, among which are CC and CXX. To
quote tools/scripts/Makefile.include, which handles this properly:
# Makefiles suck: This macro sets a default value of $(2) for the
# variable named by $(1), unless the variable has been set by
# environment or command line. This is necessary for CC and AR
# because make sets default values, so the simpler ?= approach
# won't work as expected.
In other words, the conditional assignments will not run even if the
variables are not overridden in the environment; Make will set CC to
"cc" and CXX to "g++" when it starts[1], meaning the variables are not
empty by the time the conditional assignments are evaluated. This breaks
cross-compilation when CROSS_COMPILE is set but CC isn't, since "cc"
gets used for feature detection instead of the cross compiler (and
likewise for CXX).
To fix the issue, just pass down the values of CC and CXX computed by
the parent Makefile, which gets included by the Makefile that actually
builds whatever we're detecting features for and so is guaranteed to
have good values. This is a better solution anyway, since it means we
aren't trying to replicate the logic of the parent build system and so
don't risk it getting out of sync.
Leave PKG_CONFIG alone, since 1) there's no common logic to compute it
in Makefile.include, and 2) it's not an implicit variable, so
conditional assignment works properly.

commit 401136bb084fd021acd9f8c51b52fe0a25e326b2 upstream.
While walking code towards a FUP ip, the packet state is
INTEL_PT_STATE_FUP or INTEL_PT_STATE_FUP_NO_TIP. That was mishandled
resulting in the state becoming INTEL_PT_STATE_IN_SYNC prematurely. The
result was an occasional lost EXSTOP event.

[ Upstream commit a278f3d8191228212c553a5d4303fa603214b717 ]
The '&&' command seems to have a bad effect when $(cmd_$(1)) exits with
non-zero effect: the command failure is masked (despite `set -e`) and all but
the first command of $(dep-cmd) is executed (successfully, as they are mostly
printfs), thus overall returning 0 in the end.
This means in practice that despite compilation errors, tools's build Makefile
will return success. We see this very reliably with libbpf's Makefile, which
doesn't get compilation error propagated properly. This in turns causes issues
with selftests build, as well as bpftool and other projects that rely on
building libbpf.
The fix is simple: don't use &&. Given `set -e`, we don't need to chain
commands with &&. The shell will exit on first failure, giving desired
behavior and propagating error properly.

The size of the CPU affinity mask must be large enough for
systems with a very large number of CPUs. Otherwise, tests
which try to determine the first online CPU by calling
sched_getaffinity() will fail. This makes sure that the size
of the allocated affinity mask is dependent on the number of
CPUs as reported by get_nprocs_conf().

[ Upstream commit 16f6458f2478b55e2b628797bc81a4455045c74e ]
The msg_zerocopy test pins the sender and receiver threads to separate
cores to reduce variance between runs.
But it hardcodes the cores and skips core 0, so it fails on machines
with the selected cores offline, or simply fewer cores.
The test mainly gives code coverage in automated runs. The throughput
of zerocopy ('-z') and non-zerocopy runs is logged for manual
inspection.
Continue even when sched_setaffinity fails. Just log to warn anyone
interpreting the data.

The token variable in the process_dynamic_array_len function is
allocated in the read_expect_type function, but is not freed before
calling the read_token function.
Free the token variable before calling read_token in order to plug the
leak.

commit 0e0bf1ea1147fcf74eab19c2d3c853cc3740a72f upstream.
As the code comments in perf_stat_process_counter() say, we calculate
counter's data every interval, and the display code shows ps->res_stats
avg value. We need to zero the stats for interval mode.
But the current code only zeros the res_stats[0], it doesn't zero the
res_stats[1] and res_stats[2], which are for ena and run of counter.
This patch zeros the whole res_stats[] for interval mode.
Fixes: 51fd2df1e8 ("perf stat: Fix interval output values")

Change-Id: I7b1108d90ee1109a28fe488a4358b7a3e101d9c9
commit 2ae5d0d7d8868df7c05c2013c0b9cddd4d40610e upstream.
Since commit 03db8b583d ("perf tools: Fix
maps__find_symbol_by_name()") introduced map address range check in
maps__find_symbol_by_name(), we can not get "_etext" from kernel map
because _etext is placed on the edge of the kernel .text section (=
kernel map in perf.)
To fix this issue, this checks the address correctness by map address
range information (map->start and map->end) instead of using _etext
address.
This can cause an error if the target inlined function is embedded in
both __init function and normal function.
For exaample, request_resource() is a normal function but also embedded
in __init reserve_setup(). In this case, the probe point in
reserve_setup() must be skipped.
However, without this fix, it failes to setup all probe points:
# ./perf probe -v request_resource
probe-definition(0): request_resource
symbol:request_resource file:(null) line:0 offset:0 return:0 lazy:(null)
0 arguments

commit 80526491c2ca6abc028c0f0dbb0707a1f35fb18a upstream.
Fix to check kprobe blacklist address correctly with relocated address
by adjusting debuginfo address.
Since the address in the debuginfo is same as objdump, it is different
from relocated kernel address with KASLR. Thus, 'perf probe' always
misses to catch the blacklisted addresses.
Without this patch, 'perf probe' can not detect the blacklist addresses
on a KASLR enabled kernel.
# perf probe kprobe_dispatcher
Failed to write event: Invalid argument
Error: Failed to add events.
#
With this patch, it correctly shows the error message.
# perf probe kprobe_dispatcher
kprobe_dispatcher is blacklisted function, skip it.
Probe point 'kprobe_dispatcher' not found.
Error: Failed to add events.

commit f41ebe9defacddeae96a872a33f0f22ced0bfcef upstream.
When a probe point is expanded to several places (like inlined) and if
some of them are skipped because of blacklisted or __init function,
those trace_events has no event name. It must be skipped while showing
results.
Without this fix, you can see "(null):(null)" on the list,
# ./perf probe request_resource
reserve_setup is out of .text, skip it.
Added new events:
(null):(null) (on request_resource)
probe:request_resource (on request_resource)
You can now use it in all perf tools, such as:

With this fix, it is ignored:

[ Upstream commit c6fddb28bad26e5472cb7acf7b04cd5126f1a4ab ]
The xxx_mountpoint() interface provided by fs.c finds mount points for
common pseudo filesystems. The first time xxx_mountpoint() is invoked,
it scans the mount table (/proc/mounts) looking for a match. If found,
it is cached. The price to scan /proc/mounts is paid once if the mount
is found.
When the mount point is not found, subsequent calls to xxx_mountpoint()
scan /proc/mounts over and over again. There is no caching.
This causes a scaling issue in perf record with hugeltbfs__mountpoint().
The function is called for each process found in
synthesize__mmap_events(). If the machine has thousands of processes
and if the /proc/mounts has many entries this could cause major overhead
in perf record. We have observed multi-second slowdowns on some
configurations.
As an example on a laptop:
Before:
$ sudo umount /dev/hugepages
$ strace -e trace=openat -o /tmp/tt perf record -a ls
$ fgrep mounts /tmp/tt
285
After:
$ sudo umount /dev/hugepages
$ strace -e trace=openat -o /tmp/tt perf record -a ls
$ fgrep mounts /tmp/tt
1
One could argue that the non-caching in case the moint point is not
found is intentional. That way subsequent calls may discover a moint
point if the sysadmin mounts the filesystem. But the same argument could
be made against caching the mount point. It could be unmounted causing
errors. It all depends on the intent of the interface. This patch
assumes it is expected to scan /proc/mounts once. The patch documents
the caching behavior in the fs.h header file.
An alternative would be to just fix perf record. But it would solve the
problem with hugetlbs__mountpoint() but there could be similar issues
(possibly down the line) with other xxx_mountpoint() calls in perf or
other tools.

events, the length of the 1st format of the kprobe event will not 1, but
it can be longer. This caused a parser error in perf-probe.

commit 634efb7504 ("selftests: bpf: Reset global state between
reuseport test runs") uses a macro RET_IF which doesn't exist in
the v4.19 tree. It is defined as follows:
#define RET_IF(condition, tag, format...) ({
if (CHECK_FAIL(condition)) {
printf(tag " " format);
return;
}
})
CHECK_FAIL in turn is defined as:
#define CHECK_FAIL(condition) ({
int __ret = !!(condition);
int __save_errno = errno;
if (__ret) {
test__fail();
fprintf(stdout, "%s:FAIL:%d\n", __func__, __LINE__);
}
errno = __save_errno;
__ret;
})
Replace occurences of RET_IF with CHECK. This will abort the test binary
if clearing the intermediate state fails.
