Pull perf tools fixes from Arnaldo Carvalho de Melo:
- Make 'perf kmem' cope with the removal of some
kmem:kmem_cache_alloc_node and kmem:kmalloc_node in the
11e9734bcb ("mm/slab_common: unify NUMA and UMA version of
tracepoints") commit, making sure it works with Linux >= 6.2 as well
as with older kernels where those tracepoints are present.
- Also make it handle the new "node" kmem:kmalloc and
kmem:kmem_cache_alloc tracepoint field introduced in that same
commit.
- Fix hardware tracing PMU address filter duplicate symbol selection,
that was preventing to match with static functions with the same name
present in different object files.
- Fix regression on what linux/types.h file gets used to build the "BPF
prologue" 'perf test' entry, the system one lacks the fmode_t
definition used in this test, so provide that type in the test
itself.
- Avoid build breakage with libbpf < 0.8.0 + LIBBPF_DYNAMIC=1. If the
user asks for linking with the libbpf package provided by the distro,
then it has to be >= 0.8.0. Using the libbpf supplied with the kernel
would be a fallback in that case.
- Fix the build when libbpf isn't available or explicitly disabled via
NO_LIBBPF=1.
- Don't try to install libtraceevent plugins as its not anymore in the
kernel sources and will thus always fail.

kcsan: test: don't put the expect array on the stack
In 746bd29e34 ("perf build: Use tools/lib headers from install
path") we stopped having the tools/lib/ directory from the kernel
sources in the header include path unconditionally, which breaks the
build on systems with older versions of libbpf-devel, in this case 0.7.0
as some of the structures and function declarations present in the newer
version of libbpf included in the kernel sources (tools/lib/bpf) are not
anymore used, just the ones in the system libbpf.
So instead of trying to provide alternative functions when the
libbpf-bpf_program__set_insns feature test fails, fail a
LIBBPF_DYNAMIC=1 build (requesting the use of the system's libbpf) and
emit this build error message:
$ make LIBBPF_DYNAMIC=1 -C tools/perf
Makefile.config:593: *** Error: libbpf devel library needs to be >= 0.8.0 to build with LIBBPF_DYNAMIC, update or build statically with the version that comes with the kernel sources. Stop.
$
For v6.3 these tests will be revamped and we'll require libbpf 1.0 as a
minimal version for using LIBBPF_DYNAMIC=1, most distros should have it
by now or at v6.3 time.

While running 'perf test' for bpf, observed that "BPF prologue
generation" test case fails to compile with clang. Logs below from
powerpc:
<stdin>:33:2: error: use of undeclared identifier 'fmode_t'
fmode_t f_mode = (fmode_t)_f_mode;
^
<stdin>:37:6: error: use of undeclared identifier 'f_mode'; did you mean '_f_mode'?

_f_mode
<stdin>:30:60: note: '_f_mode' declared here
int bpf_func__null_lseek(void *ctx, int err, unsigned long _f_mode,
^
2 errors generated.
The test code tests/bpf-script-test-prologue.c uses fmode_t. And the
error above is for "fmode_t" which is defined in include/linux/types.h
as part of kernel build directory: "/lib/modules/<kernel_version>/build"
that comes from kernel devel [ soft link to /usr/src/<kernel_version> ].
Clang picks this header file from "-working-directory" build option that
specifies this build folder.
But the commit 14e4b9f428 ("perf trace: Raw augmented syscalls fix
libbpf 1.0+ compatibility") changed the include directory to use:
"/usr/include".
Post this change, types.h from /usr/include/ is getting picked upwhich
doesn’t contain definition of "fmode_t" and hence fails to compile.
Compilation command before this commit:
/usr/bin/clang -D__KERNEL__ -D__NR_CPUS__=72 -DLINUX_VERSION_CODE=0x50e00 -xc -I/root/lib/perf/include/bpf -nostdinc -I./arch/powerpc/include -I./arch/powerpc/include/generated -I./include -I./arch/powerpc/include/uapi -I./arch/powerpc/include/generated/uapi -I./include/uapi -I./include/generated/uapi -include ./include/linux/compiler-version.h -include ./include/linux/kconfig.h -Wno-unused-value -Wno-pointer-sign -working-directory /lib/modules/<ver>/build -c - -target bpf -g -O2 -o -
Compilation command after this commit:

The difference is addition of -I/usr/include/ in the first line which
is causing the error. Fix this by adding typedef for "fmode_t" in the
testcase to solve the compile issue.

TPM 1 is sometimes broken across system suspends, due to races or
locking issues or something else that haven't been diagnosed or fixed
yet, most likely having to do with concurrent reads from the TPM's
hardware random number generator driver. These issues prevent the system
from actually suspending, with errors like:
tpm tpm0: A TPM error (28) occurred continue selftest
...
tpm tpm0: A TPM error (28) occurred attempting get random
...
tpm tpm0: Error (28) sending savestate before suspend
tpm_tis 00:08: PM: __pnp_bus_suspend(): tpm_pm_suspend+0x0/0x80 returns 28
tpm_tis 00:08: PM: dpm_run_callback(): pnp_bus_suspend+0x0/0x10 returns 28
tpm_tis 00:08: PM: failed to suspend: error 28
PM: Some devices failed to suspend, or early wake event detected
This issue was partially fixed by 23393c6461 ("char: tpm: Protect
tpm_pm_suspend with locks"), in a last minute 6.1 commit that Linus took
directly because the TPM maintainers weren't available. However, it
seems like this just addresses the most common cases of the bug, rather
than addressing it entirely. So there are more things to fix still,
apparently.
In lieu of actually fixing the underlying bug, just allow system suspend
to continue, so that laptops still go to sleep fine. Later, this can be
reverted when the real bug is fixed.

Commit 55d1cbbbb2 ("hfs/hfsplus: use WARN_ON for sanity check") fixed
a build warning by turning a comment into a WARN_ON(), but it turns out
that syzbot then complains because it can trigger said warning with a
corrupted hfs image.
The warning actually does warn about a bad situation, but we are much
better off just handling it as the error it is. So rather than warn
about us doing bad things, stop doing the bad things and return -EIO.
While at it, also fix a memory leak that was introduced by an earlier
fix for a similar syzbot warning situation, and add a check for one case
that historically wasn't handled at all (ie neither comment nor
subsequent WARN_ON).

Pull block fixes from Jens Axboe:
"The big change here is obviously the revert of the pktcdvd driver

- Fix for splitting of a bio marked as NOWAIT, causing either nowait
reads or writes to error with EAGAIN even if parts of the IO
completed (me)

Pull perf tools fixes from Arnaldo Carvalho de Melo:

- Fix build on uClibc systems by adding missing sys/types.h include,
that was being obtained indirectly which stopped being the case when
tools/lib/traceevent was removed.
- Don't show commands in 'perf help' that depend on linking with
libtraceevent when not building with that library, which is now a
possibility since we no longer ship a copy in tools/lib/traceevent.
- Fix failure in 'perf test' entry testing the combination of 'perf
probe' user space function + 'perf record' + 'perf script' where it
expects a backtrace leading to glibc's inet_pton() from 'ping' that
now happens more than once with glibc 2.35 for IPv6 addreses.
- Fix for the inet_pton perf test on s/390 where
'text_to_binary_address' now appears on the backtrace.
- Fix build error on riscv due to missing header for 'struct
perf_sample'.
- Fix 'make -C tools perf_install' install variant by not propagating
the 'subdir' to submakes for the 'install_headers' targets.
- Fix handling of unsupported cgroup events when using BPF counters in
'perf stat'.
- Count all cgroups, not just the last one when using 'perf stat' and
combining --for-each-cgroup with --bpf-counters.
This makes the output using BPF counters match the output without
using it, which was the intention all along, the output should be the
same using --bpf-counters or not.
- Fix 'perf lock contention' core dump related to not finding the
"__sched_text_end" symbol on s/390.
- Fix build failure when HEAD is signed: exclude the signature from the
version string.
- Add missing closedir() calls to in perf_data__open_dir(), plugging a
fd leak.

Commit fb70bf124b ("NFSD: Instantiate a struct file when creating a
regular NFSv4 file") added the ability to cache an open fd over a
compound. There are a couple of problems with the way this currently
works:
It's racy, as a newly-created nfsd_file can end up with its PENDING bit
cleared while the nf is hashed, and the nf_file pointer is still zeroed
out. Other tasks can find it in this state and they expect to see a
valid nf_file, and can oops if nf_file is NULL.
Also, there is no guarantee that we'll end up creating a new nfsd_file
if one is already in the hash. If an extant entry is in the hash with a
valid nf_file, nfs4_get_vfs_file will clobber its nf_file pointer with
the value of op_file and the old nf_file will leak.
Fix both issues by making a new nfsd_file_acquirei_opened variant that
takes an optional file pointer. If one is present when this is called,
we'll take a new reference to it instead of trying to open the file. If
the nfsd_file already has a valid nf_file, we'll just ignore the
optional file and pass the nfsd_file back as-is.
Also rework the tracepoints a bit to allow for an "opened" variant and
don't try to avoid counting acquisitions in the case where we already
have a cached open file.

If we delay sending End Transfer for Setup TRB to be prepared, we need
to check if the End Transfer was in preparation for a driver
teardown/soft-disconnect. In those cases, just send the End Transfer
command without delay.
In the case of soft-disconnect, there's a very small chance the command
may not go through immediately. But should it happen, the Setup TRB will
be prepared during the polling of the controller halted state, allowing
the command to go through then.
In the case of disabling endpoint due to reconfiguration (e.g.
set_interface(alt-setting) or usb reset), then it's driven by the host.
Typically the host wouldn't immediately cancel the control request and
send another control transfer to trigger the End Transfer command
timeout.
