9fbfc77d0f objtool: Fix stack offset tracking for indirect CFAs
commit d8dd25a461e4eec7190cb9d66616aceacc5110ad upstream.

When the current frame address (CFA) is stored on the stack (i.e.,
cfa->base == CFI_SP_INDIRECT), objtool neglects to adjust the stack
offset when there are subsequent pushes or pops.  This results in bad
ORC data at the end of the ENTER_IRQ_STACK macro, when it puts the
previous stack pointer on the stack and does a subsequent push.

This fixes the following unwinder warning:

  WARNING: can't dereference registers at 00000000f0a6bdba for ip interrupt_entry+0x9f/0xa0

17c29ddae8 selftests/ipc: Fix test failure seen after initial test run
[ Upstream commit b87080eab4c1377706c113fc9c0157f19ea8fed1 ]

After successfully running the IPC msgque test once, subsequent runs
result in a test failure:

  $ sudo ./run_kselftest.sh
  TAP version 13
  1..1
  # selftests: ipc: msgque
  # Failed to get stats for IPC queue with id 0
  # Failed to dump queue: -22
  # Bail out!
  # # Pass 0 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0
  not ok 1 selftests: ipc: msgque # exit=1

The dump_queue() function loops through the possible message queue index
values using calls to msgctl(kern_id, MSG_STAT, ...) where kern_id
represents the index value. The first time the test is ran, the initial
index value of 0 is valid and the test is able to complete. The index
value of 0 is not valid in subsequent test runs and the loop attempts to
try index values of 1, 2, 3, and so on until a valid index value is
found that corresponds to the message queue created earlier in the test.

The msgctl() syscall returns -1 and sets errno to EINVAL when invalid
index values are used. The test failure is caused by incorrectly
comparing errno to -EINVAL when cycling through possible index values.

Fix invalid test failures on subsequent runs of the msgque test by
correctly comparing errno values to a non-negated EINVAL.

6e575122cd objtool: Support Clang non-section symbols in ORC dump
[ Upstream commit 8782e7cab51b6bf01a5a86471dd82228af1ac185 ]

Historically, the relocation symbols for ORC entries have only been
section symbols:

  .text+0: sp:sp+8 bp:(und) type:call end:0

However, the Clang assembler is aggressive about stripping section
symbols.  In that case we will need to use function symbols:

  freezing_slow_path+0: sp:sp+8 bp:(und) type:call end:0

In preparation for the generation of such entries in "objtool orc
generate", add support for reading them in "objtool orc dump".

9a80ebc2d3 objtool: Fix CONFIG_UBSAN_TRAP unreachable warnings
[ Upstream commit bd841d6154f5f41f8a32d3c1b0bc229e326e640a ]

CONFIG_UBSAN_TRAP causes GCC to emit a UD2 whenever it encounters an
unreachable code path.  This includes __builtin_unreachable().  Because
the BUG() macro uses __builtin_unreachable() after it emits its own UD2,
this results in a double UD2.  In this case objtool rightfully detects
that the second UD2 is unreachable:

  init/main.o: warning: objtool: repair_env_string()+0x1c8: unreachable instruction

We weren't able to figure out a way to get rid of the double UD2s, so
just silence the warning.

a6db63ba00 tools/vm: fix cross-compile build
commit cf01699ee220c38099eb3e43ce3d10690c8b7060 upstream.

Commit 7ed1c1901f ("tools: fix cross-compile var clobbering") moved
the setup of the CC variable to tools/scripts/Makefile.include to make
the behavior consistent across all the tools Makefiles.

As the vm tools missed the include we end up with the wrong CC in a
cross-compiling evironment.

7ad65e34ad tracing/selftests: Turn off timeout setting
[ Upstream commit b43e78f65b1d35fd3e13c7b23f9b64ea83c9ad3a ]

As the ftrace selftests can run for a long period of time, disable the
timeout that the general selftests have. If a selftest hangs, then it
probably means the machine will hang too.

[ Upstream commit 6d573a07528308eb77ec072c010819c359bebf6e ]

get_test_count() and get_test_enabled() were broken for test numbers
above 9 due to awk interpreting a field specification like '$0010' as
octal rather than decimal.  Fix it by stripping the leading zeroes.

0d6f9d8f31 bpftool: Fix printing incorrect pointer in btf_dump_ptr
commit 555089fdfc37ad65e0ee9b42ca40c238ff546f83 upstream.

For plain text output, it incorrectly prints the pointer value
"void *data".  The "void *data" is actually pointing to memory that
contains a bpf-map's value.  The intention is to print the content of
the bpf-map's value instead of printing the pointer pointing to the
bpf-map's value.

In this case, a member of the bpf-map's value is a pointer type.
Thus, it should print the "*(void **)data".

2b91a2361d objtool: Fix switch table detection in .text.unlikely
commit b401efc120a399dfda1f4d2858a4de365c9b08ef upstream.

If a switch jump table's indirect branch is in a ".cold" subfunction in
.text.unlikely, objtool doesn't detect it, and instead prints a false
warning:

  drivers/media/dvb-frontends/drxk_hard.o: warning: objtool: init_drxk.cold()+0x16f: sibling call from callable instruction with modified stack frame

Fix it by comparing the function, instead of the section and offset.

d1b6feb46b perf tools: Support Python 3.8+ in Makefile
commit b9c9ce4e598e012ca7c1813fae2f4d02395807de upstream.

Python 3.8 changed the output of 'python-config --ldflags' to no longer
include the '-lpythonX.Y' flag (this apparently fixed an issue loading
modules with a statically linked Python executable).  The libpython
feature check in linux/build/feature fails if the Python library is not
included in FEATURE_CHECK_LDFLAGS-libpython variable.

This adds a check in the Makefile to determine if PYTHON_CONFIG accepts
the '--embed' flag and passes that flag alongside '--ldflags' if so.

tools/perf is the only place the libpython feature check is used.

01522e4d4a selftests: vm: drop dependencies on page flags from mlock2 tests
commit eea274d64e6ea8aff2224d33d0851133a84cc7b5 upstream.

It was noticed that mlock2 tests are failing after 9c4e6b1a70 ("mm,
mlock, vmscan: no more skipping pagevecs") because the patch has changed
the timing on when the page is added to the unevictable LRU list and thus
gains the unevictable page flag.

The test was just too dependent on the implementation details which were
true at the time when it was introduced.  Page flags and the timing when
they are set is something no userspace should ever depend on.  The test
should be testing only for the user observable contract of the tested
syscalls.  Those are defined pretty well for the mlock and there are other
means for testing them.  In fact this is already done and testing for page
flags can be safely dropped to achieve the aimed purpose.  Present bits
can be checked by /proc/<pid>/smaps RSS field and the locking state by
VmFlags although I would argue that Locked: field would be more
appropriate.

Drop all the page flag machinery and considerably simplify the test.  This
should be more robust for future kernel changes while checking the
promised contract is still valid.

7ab127c8e1 tools/accounting/getdelays.c: fix netlink attribute length
commit 4054ab64e29bb05b3dfe758fff3c38a74ba753bb upstream.

A recent change to the netlink code: 6e237d099f ("netlink: Relax attr
validation for fixed length types") logs a warning when programs send
messages with invalid attributes (e.g., wrong length for a u32).  Yafang
reported this error message for tools/accounting/getdelays.c.

send_cmd() is wrongly adding 1 to the attribute length.  As noted in
include/uapi/linux/netlink.h nla_len should be NLA_HDRLEN + payload
length, so drop the +1.

Fixes: 9e06d3f9f6 ("per task delay accounting taskstats interface: documentation fix")

[ Upstream commit 1f81c5efc020314b2db30d77efe228b7e117750d ]

Some Chromebook BIOS' do not export an ACPI LPIT, which is how
Linux finds the residency counter for CPU and SYSTEM low power states,
that is exports in /sys/devices/system/cpu/cpuidle/*residency_us

When these sysfs attributes are missing, check the debugfs attrubte
from the pmc_core driver, which accesses the same counter value.

71fc11978c perf map: Fix off by one in strncpy() size argument
commit db2c549407d4a76563c579e4768f7d6d32afefba upstream.

This patch fixes an off-by-one error in strncpy size argument in
tools/perf/util/map.c. The issue is that in:

        strncmp(filename, "/system/lib/", 11)

the passed string literal: "/system/lib/" has 12 bytes (without the NULL
byte) and the passed size argument is 11. As a result, the logic won't
match the ending "/" byte and will pass filepaths that are stored in
other directories e.g. "/system/libmalicious/bin" or just
"/system/libmalicious".

This functionality seems to be present only on Android. I assume the
/system/ directory is only writable by the root user, so I don't think
this bug has much (or any) security impact.

55831a04b5 tools: Let O= makes handle a relative path with -C option
commit be40920fbf1003c38ccdc02b571e01a75d890c82 upstream.

When I tried to compile tools/perf from the top directory with the -C
option, the O= option didn't work correctly if I passed a relative path:

  $ make O=BUILD -C tools/perf/
  make: Entering directory '/home/mhiramat/ksrc/linux/tools/perf'
    BUILD:   Doing 'make -j8' parallel build
  ../scripts/Makefile.include:4: *** O=/home/mhiramat/ksrc/linux/tools/perf/BUILD does not exist.  Stop.
  make: *** [Makefile:70: all] Error 2
  make: Leaving directory '/home/mhiramat/ksrc/linux/tools/perf'

The O= directory existence check failed because the check script ran in
the build target directory instead of the directory where I ran the make
command.

To fix that, once change directory to $(PWD) and check O= directory,
since the PWD is set to where the make command runs.

72057ab292 perf probe: Do not depend on dwfl_module_addrsym()
commit 1efde2754275dbd9d11c6e0132a4f09facf297ab upstream.

Do not depend on dwfl_module_addrsym() because it can fail on user-space
shared libraries.

Actually, same bug was fixed by commit 664fee3dc3 ("perf probe: Do not
use dwfl_module_addrsym if dwarf_diename finds symbol name"), but commit
07d369857808 ("perf probe: Fix wrong address verification) reverted to
get actual symbol address from symtab.

This fixes it again by getting symbol address from DIE, and only if the
DIE has only address range, it uses dwfl_module_addrsym().

5e8dff9964 perf bench futex-wake: Restore thread count default to online CPU count
commit f649bd9dd5d5004543bbc3c50b829577b49f5d75 upstream.

Since commit 3b2323c2c1 ("perf bench futex: Use cpumaps") the default
number of threads the benchmark uses got changed from number of online
CPUs to zero:

  $ perf bench futex wake
  # Running 'futex/wake' benchmark:
  Run summary [PID 15930]: blocking on 0 threads (at [private] futex 0x558b8ee4bfac), waking up 1 at a time.
  [Run 1]: Wokeup 0 of 0 threads in 0.0000 ms
  [...]
  [Run 10]: Wokeup 0 of 0 threads in 0.0000 ms
  Wokeup 0 of 0 threads in 0.0004 ms (+-40.82%)

Restore the old behavior by grabbing the number of online CPUs via
cpu->nr:

  $ perf bench futex wake
  # Running 'futex/wake' benchmark:
  Run summary [PID 18356]: blocking on 8 threads (at [private] futex 0xb3e62c), waking up 1 at a time.
  [Run 1]: Wokeup 8 of 8 threads in 0.0260 ms
  [...]
  [Run 10]: Wokeup 8 of 8 threads in 0.0270 ms
  Wokeup 8 of 8 threads in 0.0419 ms (+-24.35%)

a89327c1f7 ktest: Add timeout for ssh sync testing
commit 4d00fc477a2ce8b6d2b09fb34ef9fe9918e7d434 upstream.

Before rebooting the box, a "ssh sync" is called to the test machine to see
if it is alive or not. But if the test machine is in a partial state, that
ssh may never actually finish, and the ktest test hangs.

Add a 10 second timeout to the sync test, which will fail after 10 seconds
and then cause the test to reboot the test machine.

cf99e2442b selftests: forwarding: use proto icmp for {gretap, ip6gretap}_mac testing
[ Upstream commit e8023b030ce1748930e2dc76353a262fe47d4745 ]

For tc ip_proto filter, when we extract the flow via __skb_flow_dissect()
without flag FLOW_DISSECTOR_F_STOP_AT_ENCAP, we will continue extract to
the inner proto.

So for GRE + ICMP messages, we should not track GRE proto, but inner ICMP
proto.

For test mirror_gre.sh, it may make user confused if we capture ICMP
message on $h3(since the flow is GRE message). So I move the capture
dev to h3-gt{4,6}, and only capture ICMP message.

Before the fix:

fdbebb6963 selftests: fix too long argument
[ Upstream commit c363eb48ada5cf732b3f489fab799fc881097842 ]

With some shells, the command construed for install of bpf selftests becomes
too large due to long list of files:

make[1]: execvp: /bin/sh: Argument list too long
make[1]: *** [../lib.mk:73: install] Error 127

Currently, each of the file lists is replicated three times in the command:
in the shell 'if' condition, in the 'echo' and in the 'rsync'. Reduce that
by one instance by using make conditionals and separate the echo and rsync
into two shell commands. (One would be inclined to just remove the '@' at
the beginning of the rsync command and let 'make' echo it by itself;
unfortunately, it appears that the '@' in the front of mkdir silences output
also for the following commands.)

Also, separate handling of each of the lists to its own shell command.

The semantics of the makefile is unchanged before and after the patch. The
ability of individual test directories to override INSTALL_RULE is retained.

6225d10191 perf hists browser: Restore ESC as "Zoom out" of DSO/thread/etc
commit 3f7774033e6820d25beee5cf7aefa11d4968b951 upstream.

We need to set actions->ms.map since 599a2f38a9 ("perf hists browser:
Check sort keys before hot key actions"), as in that patch we bail out
if map is NULL.

6de4b024d6 perf stat: Fix shadow stats for clock events
commit 57ddf09173c1e7d0511ead8924675c7198e56545 upstream.

Commit 0aa802a794 ("perf stat: Get rid of extra clock display
function") introduced scale and unit for clock events. Thus,
perf_stat__update_shadow_stats() now saves scaled values of clock events
in msecs, instead of original nsecs. But while calculating values of
shadow stats we still consider clock event values in nsecs. This results
in a wrong shadow stat values. Ex,

  # ./perf stat -e task-clock,cycles ls
    <SNIP>
              2.60 msec task-clock:u    #    0.877 CPUs utilized
         2,430,564      cycles:u        # 1215282.000 GHz

Fix this by saving original nsec values for clock events in
perf_stat__update_shadow_stats(). After patch:

  # ./perf stat -e task-clock,cycles ls
    <SNIP>
              3.14 msec task-clock:u    #    0.839 CPUs utilized
         3,094,528      cycles:u        #    0.985 GHz

2255c29ed6 perf stat: Use perf_evsel__is_clocki() for clock events
commit eb08d006054e7e374592068919e32579988602d4 upstream.

We already have function to check if a given event is either
SW_CPU_CLOCK or SW_TASK_CLOCK. Utilize it.
