- Adjust objtool to handle a recent binutils change to not generate unused
symbols anymore. - 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. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEzv7L6UO9uDPlPSfHEsHwGGHeVUoFAmANZFcACgkQEsHwGGHe VUp0jg//UtL0PMCun6DLVf8jTLwtzlCb25/FFLyF6RpPQvt+Zpda89ZqG9R81pXm lMMc3L+2YBddVG2pnUC6jyWwZIpx+M5D0ZKa7AKY6K5o7tS/9BtCPrWwmuf+6TDi 6meLWy0hDOxSS5YifwH7LR8aj57SfsHqNfO4LF2ml857MX31Wwr/x5yryWPqho1g 8v4sK+cAesu8m7leVAVwbdSEiqEP9NMQxR3Te/4+aT3Xyqc/+EPttFJ30564/gaF Zes1CqmUB7G9l8c9igvvCNqZyYyy8OoPp/UjW6NTu7soYhutsWkz/28deiW9WGks sKiJ5E/lEIimuORj0M++85CZcS4SaH4MRbfXi2F4BisGFS8c7CSwH3457WAnCuOf FZ/kaVYN2CP9DWbBQI032hdUkWScEzF2racNQ6uXghlhLFQE3l/sBPS2WsHzKhnF Jtwt1fGEHAaC3LeI2AenmSLX8q/5chZMTByp5z7Lq97SSsrk65N5uFSuSaU6cK5G 0WDA5r6v0dy6szqzLe7mzaKdx2MOK6ygLisGBJDtYr7FZ5szHXz6e2vgJUEB82WB H21/mGf0Rl4GhHIH76W14imEWlQscp2wIEXJ8RWgoytRkWgHxBe59dMrwTB0s4jB R/KPlwA1eUzEaTBbARGMRGNv+Te/Z3QMYAXLlq1BZW3EKuw4L84= =FWZ1 -----END PGP SIGNATURE----- Merge tag 'objtool_urgent_for_v5.11_rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull objtool fixes from Borislav Petkov: - Adjust objtool to handle a recent binutils change to not generate unused symbols anymore. - 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. * tag 'objtool_urgent_for_v5.11_rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: objtool: Don't fail on missing symbol table objtool: Don't fail the kernel build on fatal errors objtool: Don't add empty symbols to the rbtree |

powerpc fixes for 5.11 #5
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. Thanks to Eirik Fuller, Libor Pechacek, Nicholas Piggin, Sandipan Das, Tulio Magno Quites Machado Filho. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEJFGtCPCthwEv2Y/bUevqPMjhpYAFAmAMrdETHG1wZUBlbGxl cm1hbi5pZC5hdQAKCRBR6+o8yOGlgF+xD/97Hl6qlS5GllC1mVHUW/eyekfqt7io XHSPeeayZddj3FhfX+eyfICUtmeQP9MXhp9Jyz/JyD+RCpIIiEbJ40CnCpsLeOFj RmRxiVX1lB8tEp5gMZnVdv8z3XDTkzt9YDPlHA7Ta/rqkD0ursF8yVnDG61ZjWnF +2uAozJp9p+nOVrd6wqd5wzdJyWyVXHCkCfyN/HD1rPAR0b6oFm8R3Pca7UR6Qk3 Nt5deAaTisl3jDT+1C+PNq/YErHeERwNyLcRP7dT7VvO9Cch2ijxqc3e0loLT1Nz bTL6bI1JhqePXZQRWRTxpk0A6yss0hWlMudSoRbQzhDbcEY+4QxK90oXevalHXcC C3e3qgO6JoN1hN4tw9kFQr1r+x+xsKpR+jO9MfE7ndFGfAPc2An5rSRbFEB6cUvr qqVh3iNHNGILeE74EyAthjGF2nZEmxI1DAFZFjoDoeWMi+VyE2MAzcIMJg22mhYx 5n64CCrqqTjhXtJgXm31L8WUKHz2JZnwwH3nTnrPXswzTMhkYp2fTQSySWCE4Zyo xygoMfnxIuNkL3hZN0cxNzjr0uGrWIdQq/JFui1Wek68qNK0NEH5r5FmDTTFgk0D A3sJAEmKehs3Ka64LA5ejYza0zU1wnrOcyJKDpxQAWKldcKiQQw7Gup9dQe218Vc ZemyuT9YDlOilQ== =4nYe -----END PGP SIGNATURE----- Merge tag 'powerpc-5.11-5' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: - Fix a bad interaction between the scv handling and the fallback L1D flush, which could lead to user register corruption.

perf tools fixes for 5.11, 2nd batch:
- Fix id index used in Intel PT for heterogeneous systems.
- Fix overrun issue in 'perf script' for dynamically-allocated PMU type number.
- Fix 'perf stat' metrics containing the 'duration_time' synthetic event.
- Fix system PMU 'perf stat' metrics.
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
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.

objtool: Don't fail on missing symbol table
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.

perf script: Fix overrun issue for dynamically-allocated PMU type number
When unpacking the event which is from dynamic PMU, the array
output[OUTPUT_TYPE_MAX] may be overrun. For example, type number of SKL
uncore_imc is 10, but OUTPUT_TYPE_MAX is 7 now (OUTPUT_TYPE_MAX =
PERF_TYPE_MAX + 1).
/* In builtin-script.c */
process_event()
{
unsigned int type = output_type(attr->type);
if (output[type].fields == 0)
return;
}
output[10] is overrun.
Create a type OUTPUT_TYPE_OTHER for dynamic PMU events, then
output_type(attr->type) will return OUTPUT_TYPE_OTHER here.
Note that if PERF_TYPE_MAX ever changed, then there would be a conflict
between old perf.data files that had a dynamicaliy allocated PMU number
that would then be the same as a fixed PERF_TYPE.
Example:
# perf record --switch-events -C 0 -e "{cpu-clock,uncore_imc/data_reads/,uncore_imc/data_writes/}:SD" -a -- sleep 1

perf metricgroup: Fix system PMU metrics
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().

perf evlist: Fix id index for heterogeneous systems
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().

selftests/powerpc: Only test lwm/stmw on big endian
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.

tools: gpio: fix %llu warning in gpio-event-mon.c
Some platforms, such as mips64, don't map __u64 to long long unsigned
int so using %llu produces a warning:

perf tools fixes for 5.11:
- Fix 'CPU too large' error in Intel PT.
- Correct event attribute sizes in 'perf inject'.
- Sync build_bug.h and kvm.h kernel copies.
- Fix bpf.h header include directive in 5sec.c 'perf trace' bpf example.
- libbpf tests fixes.
- Fix shadow stat 'perf test' for non-bash shells.
- Take cgroups into account for shadow stats in 'perf stat'.

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.

kunit: tool: move kunitconfig parsing into __init__, make it optional
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.

kunit: tool: fix minor typing issue with None status
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

kunit: tool: surface and address more typing issues
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.

perf inject: Correct event attribute sizes
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.

perf stat: Take cgroups into account for shadow stats
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

perf stat: Introduce struct runtime_stat_data
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.

selftests/bpf: Add verifier test for PTR_TO_MEM spill
Add a test to check that the verifier is able to recognize spilling of PTR_TO_MEM registers, by reserving a ringbuf buffer, forcing the spill of a pointer holding the buffer address to the stack, filling it back in from the stack and writing to the memory area pointed by it.

objtool: Don't add empty symbols to the rbtree
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.

libbpf: Allow loading empty BTFs
Empty BTFs do come up (e.g., simple kernel modules with no new types and
strings, compared to the vmlinux BTF) and there is nothing technically wrong
with them. So remove unnecessary check preventing loading empty BTFs.

bpf: Update local storage test to check handling of null ptrs
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.
