commit 3346a6a4e5ba8c040360f753b26938cec31a4bdc upstream.
sysret_ss_attrs fails to compile leading x86 test run to fail on systems
configured to build using PIE by default. Add -no-pie fix it.
Relocation might still fail if relocated above 4G. For now this change
fixes the build and runs x86 tests.

commit d12fe87e62d773e81e0cb3a123c5a480a10d7d91 upstream.
Fix the debug print statements in these tests where they reference
si_codes and in particular __SI_FAULT. __SI_FAULT is a kernel
internal value and should never be seen by userspace.
While I am in there also fix si_code_str. si_codes are an enumeration
there are not a bitmap so == and not & is the apropriate operation to
test for an si_code.

commit 2195bff041486eb7fcceaf058acaedcd057efbdc upstream.
The siginfo contains a bunch of information about the fault.
For protection keys, it tells us which protection key's
permissions were violated.
The wrong offset in here leads to reading garbage and thus
failures in the tests.
We should probably eventually move this over to using the
kernel's headers defining the siginfo instead of a hard-coded
offset. But, for now, just do the simplest fix.

commit 40c21898ba5372c14ef71717040529794a91ccc2 upstream.
When printing stats in CSV mode, 'perf stat' appends extra separators
when a counter is not supported:
<not supported>,,L1-dcache-store-misses,mesos/bd442f34-2b4a-47df-b966-9b281f9f56fc,0,100.00,,,,
Which causes a failure when parsing fields. The numbers of separators
should be the same for each line, no matter if the counter is or not
supported.

commit 4b0b37d4cc54b21a6ecad7271cbc850555869c62 upstream.
glibc keeps getting cleverer, and my version now turns raise() into
more than one syscall. Since the test relies on ptrace seeing an
exact set of syscalls, this breaks the test. Replace raise(SIGSTOP)
with syscall(SYS_tgkill, ...) to force glibc to get out of our way.

[ Upstream commit 8b06b884cd98f7ec8b5028680b99fabfb7b3e192 ]
Keep the nfit_test instances alive until after nfit_test_teardown(), as
we may be doing resource lookups until the final un-registrations have
completed. This fixes crashes of the form.

commit 78393fdde2a456cafa414b171c90f26a3df98b20 upstream.
POPF is currently broken -- add tests to catch the error. This
results in:
[RUN] POPF with VIP set and IF clear from vm86 mode
[INFO] Exited vm86 mode due to STI
[FAIL] Incorrect return reason (started at eip = 0xd, ended at eip = 0xf)
because POPF currently fails to check IF before reporting a pending
interrupt.
This patch also makes the FAIL message a bit more informative.

commit a9e017d5619eb371460c8e516f4684def62bef3a upstream.
The STR and SLDT instructions are not valid when running on virtual-8086
mode and generate an invalid operand exception. These two instructions are
protected by the Intel User-Mode Instruction Prevention (UMIP) security
feature. In protected mode, if UMIP is enabled, these instructions generate
a general protection fault if called from CPL > 0. Linux traps the general
protection fault and emulates the instructions sgdt, sidt and smsw; but not
str and sldt.
These tests are added to verify that the emulation code does not emulate
these two instructions but the expected invalid operand exception is
seen.
Tests fallback to exit with INT3 in case emulation does happen.

commit 9390afebe1d3f5a0be18b1afdd0ce09d67cebf9e upstream.
Certain user space programs that run on virtual-8086 mode may utilize
instructions protected by the User-Mode Instruction Prevention (UMIP)
security feature present in new Intel processors: SGDT, SIDT and SMSW. In
such a case, a general protection fault is issued if UMIP is enabled. When
such a fault happens, the kernel traps it and emulates the results of
these instructions with dummy values. The purpose of this new
test is to verify whether the impacted instructions can be executed
without causing such #GP. If no #GP exceptions occur, we expect to exit
virtual-8086 mode from INT3.
The instructions protected by UMIP are executed in representative use
cases:
a) displacement-only memory addressing
b) register-indirect memory addressing
c) results stored directly in operands
Unfortunately, it is not possible to check the results against a set of
expected values because no emulation will occur in systems that do not
have the UMIP feature. Instead, results are printed for verification. A
simple verification is done to ensure that results of all tests are
identical.

[ Upstream commit 2adfa4210f8f35cdfb4e08318cc06b99752964c2 ]
The 'configinit.sh' script checks the format of optional argument for the
build directory, printing an error message if the format is not valid.
However, the error message uses the wrong variable, indicating an empty
string even though the user entered a non-empty (but erroneous) string.
This commit fixes the script to use the correct variable.

Indeed musl doesn't define old SIGCLD signal name but only new one SIGCHLD.
SIGCHLD is the new POSIX name for that signal so it doesn't change
anything on other libcs.

The file /sys/module/firmware_class/parameters/path can be used
to set a custom firmware path. The fw_filesystem.sh script creates
a temporary directory to add a test firmware file to be used during
testing, in order for this to work it uses the custom path syfs file
and it was supposed to reset back the file on execution exit. The
script failed to do this due to a typo, it was using OLD_PATH instead
of OLD_FWPATH, since its inception since v3.17.
Its not as easy to just keep the old setting, it turns out that
resetting an empty setting won't actually do what we want, we need
to check if it was empty and set an empty space.
Without this we end up having the temporary path always set after
we run these tests.

[ Upstream commit db49a71798a38f3ddf3f3462703328dca39b1ac7 ]
(This is a patch has been sitting in the Intel CQM/CMT driver series for
a while, despite not depend on it. Sending it now independently since
the series is being discarded.)
When an event is in error state, read() returns 0 instead of sizeof()
buffer. In certain modes, such as interval printing, ignoring the 0
return value may cause bogus count deltas to be computed and thus
invalid results printed.
This patch fixes this problem by modifying read_counters() to mark the
event as not scaled (scaled = -1) to force the printout routine to show
<NOT COUNTED>.

__perf_session__process_pipe_events reuses the same memory buffer to
process all events in the pipe.
When reordering is needed (e.g. -b option), events are not immediately
flushed, but kept around until reordering is possible, causing
memory corruption.
The problem is usually observed by a "Unknown sample error" output. It
can easily be reproduced by:
perf record -o - noploop | perf inject -b > output

Before:
$ perf record -o - stress -t 2 -c 2 | perf inject -b > /dev/null

[ Upstream commit 32ccb130f5325abc81b32b1a538390f46e4860f6 ]
The kernel has a special check for a specific irq_vectors trace event.
TRACE_EVENT_PERF_PERM(irq_work_exit,
is_sampling_event(p_event) ? -EPERM : 0);
The perf-record fails for this irq_vectors event when it is present,
like when using a wildcard:
root@skl:/tmp# perf record -a -e irq_vectors:* sleep 2
Error:
You may not have permission to collect system-wide stats.
Consider tweaking /proc/sys/kernel/perf_event_paranoid,
which controls use of the performance events system by
unprivileged users (without CAP_SYS_ADMIN).
The current value is 2:
-1: Allow use of (almost) all events by all users
>= 0: Disallow raw tracepoint access by users without CAP_IOC_LOCK
>= 1: Disallow CPU event access by users without CAP_SYS_ADMIN
>= 2: Disallow kernel profiling by users without CAP_SYS_ADMIN
To make this setting permanent, edit /etc/sysctl.conf too, e.g.:
kernel.perf_event_paranoid = -1
This patch prints out the exact sub event that failed with EPERM for
wildcards to help in understanding what went wrong when this event is
present:
After the patch:
root@skl:/tmp# perf record -a -e irq_vectors:* sleep 2
Error:
No permission to enable irq_vectors:irq_work_exit event.
You may not have permission to collect system-wide stats.
......
Committer notes:
So we have a lot of irq_vectors events:
[root@jouet ~]# perf list irq_vectors:*
List of pre-defined events (to be used in -e):
irq_vectors:call_function_entry [Tracepoint event]
irq_vectors:call_function_exit [Tracepoint event]
irq_vectors:call_function_single_entry [Tracepoint event]
irq_vectors:call_function_single_exit [Tracepoint event]
irq_vectors:deferred_error_apic_entry [Tracepoint event]
irq_vectors:deferred_error_apic_exit [Tracepoint event]

irq_vectors:irq_work_entry [Tracepoint event]
irq_vectors:irq_work_exit [Tracepoint event]
irq_vectors:local_timer_entry [Tracepoint event]

irq_vectors:threshold_apic_exit [Tracepoint event]
irq_vectors:x86_platform_ipi_entry [Tracepoint event]
irq_vectors:x86_platform_ipi_exit [Tracepoint event]
#
And some may be sampled:
[root@jouet ~]# perf record -e irq_vectors:local* sleep 20s
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.020 MB perf.data (2 samples) ]
[root@jouet ~]# perf report -D | egrep 'stats:|events:'
Aggregated stats:
TOTAL events: 155
MMAP events: 144
COMM events: 2
EXIT events: 1
SAMPLE events: 2
MMAP2 events: 4
FINISHED_ROUND events: 1
TIME_CONV events: 1
irq_vectors:local_timer_entry stats:
TOTAL events: 1
SAMPLE events: 1
irq_vectors:local_timer_exit stats:
TOTAL events: 1
SAMPLE events: 1
[root@jouet ~]#
But, as shown in the tracepoint definition at the start of this message,
some, like "irq_vectors:irq_work_exit", may not be sampled, just counted,
i.e. if we try to sample, as when using 'perf record', we get an error:
[root@jouet ~]# perf record -e irq_vectors:irq_work_exit
Error:
You may not have permission to collect system-wide stats.
Consider tweaking /proc/sys/kernel/perf_event_paranoid,
<SNIP>
The error message is misleading, this patch will help in pointing out
what is the event causing such an error, but the error message needs
improvement, i.e. we need to figure out a way to check if a tracepoint
is counting only, like this one, when all we can do is to count it with
'perf stat', at most printing the delta using interval printing, as in:
[root@jouet ~]# perf stat -I 5000 -e irq_vectors:irq_work_*
# time counts unit events
5.000168871 0 irq_vectors:irq_work_entry
5.000168871 0 irq_vectors:irq_work_exit
10.000676730 0 irq_vectors:irq_work_entry
10.000676730 0 irq_vectors:irq_work_exit
15.001122415 0 irq_vectors:irq_work_entry
15.001122415 0 irq_vectors:irq_work_exit
20.001298051 0 irq_vectors:irq_work_entry
20.001298051 0 irq_vectors:irq_work_exit
25.001485020 1 irq_vectors:irq_work_entry
25.001485020 1 irq_vectors:irq_work_exit
30.001658706 0 irq_vectors:irq_work_entry
30.001658706 0 irq_vectors:irq_work_exit
^C 32.045711878 0 irq_vectors:irq_work_entry
32.045711878 0 irq_vectors:irq_work_exit
[root@jouet ~]#
But at least, when we use a wildcard, this patch helps a bit.

Which may happen when we start a tracing session and a thread is waiting
for something like "poll" to return, in which case we better print "?"
both for the syscall entry timestamp and for the duration.
E.g.:
Tracing existing mutt session:
# perf trace -p `pidof mutt`
? ( ? ): mutt/17135 ... [continued]: poll()) = 1
0.027 ( 0.013 ms): mutt/17135 read(buf: 0x7ffcb3c42cef, count: 1) = 1
0.047 ( 0.008 ms): mutt/17135 poll(ufds: 0x7ffcb3c42c50, nfds: 1, timeout_msecs: 1000) = 1
0.059 ( 0.008 ms): mutt/17135 read(buf: 0x7ffcb3c42cef, count: 1) = 1
<SNIP>
Before it would print a large number because we'd do:
ttrace->entry_time - trace->base_time
And entry_time would be 0, while base_time would be the timestamp for
the first event 'perf trace' reads, oops.

it is symbolic link, so fix it.

is a symbolic link, instead of the above build-id file name like below.

[ Upstream commit 88b897a30c525c2eee6e7f16e1e8d0f18830845e ]
This patch significantly improves the execution time of
perf_event__synthesize_mmap_events() when running perf record on systems
where processes have lots of threads.
It just happens that cat /proc/pid/maps support uses a O(N^2) algorithm to
generate each map line in the maps file. If you have 1000 threads, then you
have necessarily 1000 stacks. For each vma, you need to check if it
corresponds to a thread's stack. With a large number of threads, this can take
a very long time. I have seen latencies >> 10mn.
As of today, perf does not use the fact that a mapping is a stack, therefore we
can work around the issue by using /proc/pid/tasks/pid/maps. This entry does
not try to map a vma to stack and is thus much faster with no loss of
functonality.
The proc-map-timeout logic is kept in case users still want some upper limit.
In V2, we fix the file path from /proc/pid/tasks/pid/maps to actual
/proc/pid/task/pid/maps, tasks -> task. Thanks Arnaldo for catching this.
Committer note:
This problem seems to have been elliminated in the kernel since commit :
b18cb64ead ("fs/proc: Stop trying to report thread stacks").

[ Upstream commit 02d492e5dcb72c004d213756eb87c9d62a6d76a7 ]
When using perf stat on an AMD F15h system with the default hw events
attributes, some of the events don't get counted:
Performance counter stats for 'sleep 1':
0.749208 task-clock (msec) # 0.001 CPUs utilized
1 context-switches # 0.001 M/sec
0 cpu-migrations # 0.000 K/sec
54 page-faults # 0.072 M/sec
1,122,815 cycles # 1.499 GHz
286,740 stalled-cycles-frontend # 25.54% frontend cycles idle
<not counted> stalled-cycles-backend (0.00%)
^^^^^^^^^^^^
<not counted> instructions (0.00%)
^^^^^^^^^^^^
<not counted> branches (0.00%)
<not counted> branch-misses (0.00%)
1.001550070 seconds time elapsed
The reason is that we have the HW watchdog consuming one PMU counter and
when perf tries to schedule 6 events on 6 counters and some of those
counters are constrained to only a specific subset of PMCs by the
hardware, the event scheduling fails.
So issue a hint to disable the HW watchdog around a perf stat session.
Committer note:
Testing it...
# perf stat -d usleep 1
Performance counter stats for 'usleep 1':
1.180203 task-clock (msec) # 0.490 CPUs utilized
1 context-switches # 0.847 K/sec
0 cpu-migrations # 0.000 K/sec
54 page-faults # 0.046 M/sec
184,754 cycles # 0.157 GHz
714,553 instructions # 3.87 insn per cycle
154,661 branches # 131.046 M/sec
7,247 branch-misses # 4.69% of all branches
219,984 L1-dcache-loads # 186.395 M/sec
17,600 L1-dcache-load-misses # 8.00% of all L1-dcache hits (90.16%)
<not counted> LLC-loads (0.00%)
<not counted> LLC-load-misses (0.00%)
0.002406823 seconds time elapsed
Some events weren't counted. Try disabling the NMI watchdog:
echo 0 > /proc/sys/kernel/nmi_watchdog
perf stat ...
echo 1 > /proc/sys/kernel/nmi_watchdog

trigger_on() means that the trigger is available but not ready, however
trigger_on() was making it ready. That can segfault if the signal comes
before trigger_ready(). e.g. (USR2 signal delivery not shown)

commit e572d0887137acfc53f18175522964ec19d88175 upstream.
When doing a kernel build with 'make -s', everything is silenced except
the objtool build. That's because the tools tree support for silent
builds is some combination of missing and broken.
Three changes are needed to fix it:
- Makefile: propagate '-s' to the sub-make's MAKEFLAGS variable so the
tools Makefiles can see it.
- tools/scripts/Makefile.include: fix the tools Makefiles' ability to
recognize '-s'. The MAKE_VERSION and MAKEFLAGS checks are copied from
the top-level Makefile. This silences the "DESCEND objtool" message.
- tools/build/Makefile.build: add support to the tools Build files for
recognizing '-s'. Again the MAKE_VERSION and MAKEFLAGS checks are
copied from the top-level Makefile. This silences all the object
compile/link messages.

[ Upstream commit 321a7c35c90cc834851ceda18a8ee18f1d032b92 ]
Certain systems are designed to have sparse/discontiguous nodes. On
such systems, 'perf bench numa' hangs, shows wrong number of nodes and
shows values for non-existent nodes. Handle this by only taking nodes
that are exposed by kernel to userspace.

[ Upstream commit 89d0aeab4252adc2a7ea693637dd21c588bfa2d1 ]
The stdio perf top crashes when we change the terminal
window size. The reason is that we assumed we get the
perf_top pointer as a signal handler argument which is
not the case.
Changing the SIGWINCH handler logic to change global
resize variable, which is checked in the main thread

commit 4105c69703cdeba76f384b901712c9397b04e9c2 upstream.
On 64-bit builds, we should not rely on "int $0x80" working (it only does if
CONFIG_IA32_EMULATION=y is enabled). To keep the "Set TF and check int80"
test running on 64-bit installs with CONFIG_IA32_EMULATION=y enabled, build
this test only if we can also build 32-bit binaries (which should be a
good approximation for that).

On 64-bit builds, we should not rely on "int $0x80" working (it only does if
CONFIG_IA32_EMULATION=y is enabled).
Without this patch, the move test may succeed, but the "int $0x80" causes
a segfault, resulting in a false negative output of this self-test.

commit 4c1baad223906943b595a887305f2e8124821dad upstream.
Running the compaction_test sometimes results in out-of-memory
failures. When I debugged this, it turned out that the code to
reset the number of hugepages to the initial value is simply
broken since we write into an open sysctl file descriptor
multiple times without seeking back to the start.
Adding the lseek here fixes the problem.
