Pull libnvdimm fixes from Dan Williams:
"A fix for a crash scenario that has been present since the initial
merge, a minor regression in sysfs attribute visibility, and a fix for
some flexible array warnings.
The bulk of this pull is an update to the libnvdimm unit test
infrastructure to test non-ACPI platforms. Given there is zero
regression risk for test updates, and the tests enable validation of
bits headed towards the next merge window, I saw no reason to hold the
new tests back. Santosh originally submitted this before the v5.11
window opened.
Summary:
- Fix a crash when sysfs accesses race 'dimm' driver probe/remove.
- Fix a regression in 'resource' attribute visibility necessary for
mapping badblocks and other physical address interrogations.
- Fix some flexible array warnings
- Expand the unit test infrastructure for non-ACPI platforms"

entry: Use different define for selector variable in SUD
Michael Kerrisk suggested that, from an API perspective, it is a bad idea to share the PR_SYS_DISPATCH_ defines between the prctl operation and the selector variable. Therefore, define two new constants to be used by SUD's selector variable and update the corresponding documentation and test cases. While this changes the API syscall user dispatch has never been part of a Linux release, it will show up for the first time in 5.11.

dma-mapping: benchmark: use u8 for reserved field in uAPI structure
The original code put five u32 before a u64 expansion[10] array. Five is odd, this will cause trouble in the extension of the structure by adding new features. This patch moves to use u8 for reserved field to avoid future alignment risk. Meanwhile, it also clears the memory of struct map_benchmark in tools, otherwise, if users use old version to run on newer kernel, the random expansion value will cause side effect on newer kernel.

Networking fixes for 5.11-rc6, including fixes from can, xfrm, wireless,
wireless-drivers and netfilter trees. Nothing scary, Intel WiFi-related
fixes seemed most notable to the users.
Current release - regressions:
- dsa: microchip: ksz8795: fix KSZ8794 port map again to program
the CPU port correctly
Current release - new code bugs:
- iwlwifi: pcie: reschedule in long-running memory reads
Previous releases - regressions:
- iwlwifi: dbg: don't try to overwrite read-only FW data
- iwlwifi: provide gso_type to GSO packets
- octeontx2: make sure the buffer is 128 byte aligned
- tcp: make TCP_USER_TIMEOUT accurate for zero window probes
- xfrm: fix wraparound in xfrm_policy_addr_delta()
- xfrm: fix oops in xfrm_replay_advance_bmp due to a race between CPUs
in presence of packet reorder
- tcp: fix TLP timer not set when CA_STATE changes from DISORDER
to OPEN
- wext: fix NULL-ptr-dereference with cfg80211's lack of commit()
Previous releases - always broken:
- igc: fix link speed advertising
- stmmac: configure EHL PSE0 GbE and PSE1 GbE to 32 bits DMA addressing
- team: protect features update by RCU to avoid deadlock
- xfrm: fix disable_xfrm sysctl when used on xfrm interfaces themselves
- fec: fix temporary RMII clock reset on link up
- can: dev: prevent potential information leak in can_fill_info()
Misc:
- mrp: fix bad packing of MRP test packet structures
- uapi: fix big endian definition of ipv6_rpl_sr_hdr
- add David Ahern to IPv4/IPv6 maintainers

testing/nvdimm: Add test module for non-nfit platforms
The current test module cannot be used for testing platforms (make check) that do not have support for NFIT. In order to get the ndctl tests working, we need a module which can emulate NVDIMM devices without relying on ACPI/NFIT. The aim of this proposed module is to implement a similar functionality to the existing module but without the ACPI dependencies. This RFC series is split into reviewable and compilable chunks. This patch adds a new driver and registers two nvdimm bus needed for ndctl make check.

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 script

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().
Fixes:

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().

Pull networking fixes from Jakub Kicinski:
"Networking fixes for 5.11-rc5, including fixes from bpf, wireless, and
can trees.
Current release - regressions:
- nfc: nci: fix the wrong NCI_CORE_INIT parameters
Current release - new code bugs:
- bpf: allow empty module BTFs
Previous releases - regressions:
- bpf: fix signed_{sub,add32}_overflows type handling
- tcp: do not mess with cloned skbs in tcp_add_backlog()
- bpf: prevent double bpf_prog_put call from bpf_tracing_prog_attach
- bpf: don't leak memory in bpf getsockopt when optlen == 0
- tcp: fix potential use-after-free due to double kfree()
- mac80211: fix encryption issues with WEP
- devlink: use right genl user_ptr when handling port param get/set
- ipv6: set multicast flag on the multicast route
- tcp: fix TCP_USER_TIMEOUT with zero window
Previous releases - always broken:
- bpf: local storage helpers should check nullness of owner ptr passed
- mac80211: fix incorrect strlen of .write in debugfs
- cls_flower: call nla_ok() before nla_next()
- skbuff: back tiny skbs with kmalloc() in __netdev_alloc_skb() too"

selftests: net: fib_tests: remove duplicate log test
The previous test added an address with a specified metric and check if
correspond route was created. I somehow added two logs for the same
test. Remove the duplicated one.

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.

selftests/powerpc: Fix exit status of pkey tests
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. Fixes: |

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.

pull-request: bpf 2021-01-16
1) Fix a double bpf_prog_put() for BPF_PROG_{TYPE_EXT,TYPE_TRACING} types in
link creation's error path causing a refcount underflow, from Jiri Olsa.
2) Fix BTF validation errors for the case where kernel modules don't declare
any new types and end up with an empty BTF, from Andrii Nakryiko.
3) Fix BPF local storage helpers to first check their {task,inode} owners for
being NULL before access, from KP Singh.
4) Fix a memory leak in BPF setsockopt handling for the case where optlen is
zero and thus temporary optval buffer should be freed, from Stanislav Fomichev.
5) Fix a syzbot memory allocation splat in BPF_PROG_TEST_RUN infra for
raw_tracepoint caused by too big ctx_size_in, from Song Liu.

arm64 fixes:
- Set the minimum GCC version to 5.1 for arm64 due to earlier compiler bugs. - Make atomic helpers __always_inline to avoid a section mismatch when compiling with clang. - Fix the CMA and crashkernel reservations to use ZONE_DMA (remove the arm64_dma32_phys_limit variable, no longer needed with a dynamic ZONE_DMA sizing in 5.11). - Remove redundant IRQ flag tracing that was leaving lockdep inconsistent with the hardware state. - Revert perf events based hard lockup detector that was causing smp_processor_id() to be called in preemptible context. - Some trivial cleanups - spelling fix, renaming S_FRAME_SIZE to PT_REGS_SIZE, function prototypes added. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAmAB2zoACgkQa9axLQDI XvE2vA//Vjh7bKMlNtocP7oA0/FVA7i9tKgNxDYmxjYvl6qDg26V7aDMelIi9H6l 14k+Wbf2Eqkav3+aAGEwdXuaoYPGrZIfVkPf+BbuviluoGsjwaGak0pc29ofDjE4 zaznZNXwO+joEqrtEZeTQO8fSagAupbgqf3ls/pRjBGVL6XEajhPqA+ccgQB71DI O+L0Z1tzQDurABp4mwHGFRbOTMdN59OhxfyHijO3yu+RGLQcO3C29AwuMkzJuYuA Fjng+VNS4mrKT8bsP0fpJa/oNekJ4jc/2OQaLxN+re8J+o6/EG6QGKdUL4VlEllk eK0chdC/ZD1e6R9MSV0ZL1diYedi0vn+F9mGxwNiSKtWzw0KqPEy7liP0KWQGVyF NALShoGkKMglYj2fmOrZhs7E4vAQGPlk7hROssDTM1RSu/7JpBwEJRb9QsOM4p4T HgcCoF4smnTCmbyVkcMYgZxMrJ5YOjchTu8uvUwHy6D//ZMQmDE2m3u9Svziu+y3 Nk8VpIp0HNDZyA7ZTeOrmo2jSEOoK3tDVKiqorPSmZd5mp35BMCr1q/Rcu6uaywr 4ym/CfmvQIqObzQOYbBze6QZs4DLqERP1p0WgEnWBE8W2rP4UcGaNdegbEsMkrfq CiCGcNyfpiJNZSc8VF1/1OFY/yABcWem1pVM7F254zA5G2wZX1U= =W9th -----END PGP SIGNATURE----- Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 fixes from Catalin Marinas: - Set the minimum GCC version to 5.1 for arm64 due to earlier compiler bugs. - Make atomic helpers __always_inline to avoid a section mismatch when compiling with clang. - Fix the CMA and crashkernel reservations to use ZONE_DMA (remove the arm64_dma32_phys_limit variable, no longer needed with a dynamic ZONE_DMA sizing in 5.11). - Remove redundant IRQ flag tracing that was leaving lockdep inconsistent with the hardware state. - Revert perf events based hard lockup detector that was causing smp_processor_id() to be called in preemptible context. - Some trivial cleanups - spelling fix, renaming S_FRAME_SIZE to PT_REGS_SIZE, function prototypes added. * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: selftests: Fix spelling of 'Mismatch' arm64: syscall: include prototype for EL0 SVC functions compiler.h: Raise minimum version of GCC to 5.1 for arm64 arm64: make atomic helpers __always_inline arm64: rename S_FRAME_SIZE to PT_REGS_SIZE Revert "arm64: Enable perf events based hard lockup detector" arm64: entry: remove redundant IRQ flag tracing arm64: Remove arm64_dma32_phys_limit and its uses |

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. Readers see a corrupt file. Update the size field to match the layout.
