thermal/tools/tmon: Include pthread and time headers in tmon.h
Include sys/time.h and pthread.h in tmon.h, so that types
"pthread_mutex_t" and "struct timeval tv" are known when tmon.h
references them.
Without these headers, compiling tmon against musl-libc will fail with
these errors:
In file included from sysfs.c:31:0:

Previously, they got included to the kernel binary but were silently ignored at run-time. - Allow root user to append new hashes to the blacklist keyring. - Trusted keys backed with Cryptographic Acceleration and Assurance Module (CAAM), which part of some of the new NXP's SoC's. Now there is total three hardware backends for trusted keys: TPM, ARM TEE and CAAM. - A scattered set of fixes and small improvements for the TPM driver.

Perf events changes for this cycle were:
Platform PMU changes:
=====================
- x86/intel:
- Add new Intel Alder Lake and Raptor Lake support
- x86/amd:
- AMD Zen4 IBS extensions support
- Add AMD PerfMonV2 support
- Add AMD Fam19h Branch Sampling support
Generic changes:
================
- signal: Deliver SIGTRAP on perf event asynchronously if blocked
Perf instrumentation can be driven via SIGTRAP, but this causes a problem
when SIGTRAP is blocked by a task & terminate the task.
Allow user-space to request these signals asynchronously (after they get
unblocked) & also give the information to the signal handler when this
happens:
" To give user space the ability to clearly distinguish synchronous from
asynchronous signals, introduce siginfo_t::si_perf_flags and
TRAP_PERF_FLAG_ASYNC (opted for flags in case more binary information is
required in future).
The resolution to the problem is then to (a) no longer force the signal
(avoiding the terminations), but (b) tell user space via si_perf_flags
if the signal was synchronous or not, so that such signals can be
handled differently (e.g. let user space decide to ignore or consider
the data imprecise). "
- Unify/standardize the /sys/devices/cpu/events/* output format.
- Misc fixes & cleanups.

Objtool changes for this cycle were:
- Comprehensive interface overhaul:
=================================
Objtool's interface has some issues:
- Several features are done unconditionally, without any way to turn
them off. Some of them might be surprising. This makes objtool
tricky to use, and prevents porting individual features to other
arches.
- The config dependencies are too coarse-grained. Objtool enablement is
tied to CONFIG_STACK_VALIDATION, but it has several other features
independent of that.
- The objtool subcmds ("check" and "orc") are clumsy: "check" is really
a subset of "orc", so it has all the same options. The subcmd model
has never really worked for objtool, as it only has a single purpose:
"do some combination of things on an object file".
- The '--lto' and '--vmlinux' options are nonsensical and have
surprising behavior.
Overhaul the interface:
- get rid of subcmds
- make all features individually selectable
- remove and/or clarify confusing/obsolete options
- update the documentation
- fix some bugs found along the way
- Fix x32 regression
- Fix Kbuild cleanup bugs
- Add scripts/objdump-func helper script to disassemble a single function from an object file.
- Rewrite scripts/faddr2line to be section-aware, by basing it on 'readelf',
moving it away from 'nm', which doesn't handle multiple sections well,
which can result in decoding failure.
- Rewrite & fix symbol handling - which had a number of bugs wrt. object files
that don't have global symbols - which is rare but possible. Also fix a
bunch of symbol handling bugs found along the way.

tools/certs: Add print-cert-tbs-hash.sh
Add a new helper print-cert-tbs-hash.sh to generate a TBSCertificate hash from a given certificate. This is useful to generate a blacklist key description used to forbid loading a specific certificate in a keyring, or to invalidate a certificate provided by a PKCS#7 file. This kind of hash formatting is required to populate the file pointed out by CONFIG_SYSTEM_BLACKLIST_HASH_LIST, but only the kernel code was available to understand how to effectively create such hash.

landlock: Add support for file reparenting with LANDLOCK_ACCESS_FS_REFER
Add a new LANDLOCK_ACCESS_FS_REFER access right to enable policy writers to allow sandboxed processes to link and rename files from and to a specific set of file hierarchies. This access right should be composed with LANDLOCK_ACCESS_FS_MAKE_* for the destination of a link or rename, and with LANDLOCK_ACCESS_FS_REMOVE_* for a source of a rename. This lift a Landlock limitation that always denied changing the parent of an inode. Renaming or linking to the same directory is still always allowed, whatever LANDLOCK_ACCESS_FS_REFER is used or not, because it is not considered a threat to user data. However, creating multiple links or renaming to a different parent directory may lead to privilege escalations if not handled properly. Indeed, we must be sure that the source doesn't gain more privileges by being accessible from the destination. This is handled by making sure that the source hierarchy (including the referenced file or directory itself) restricts at least as much the destination hierarchy. If it is not the case, an EXDEV error is returned, making it potentially possible for user space to copy the file hierarchy instead of moving or linking it. Instead of creating different access rights for the source and the destination, we choose to make it simple and consistent for users. Indeed, considering the previous constraint, it would be weird to require such destination access right to be also granted to the source (to make it a superset). Moreover, RENAME_EXCHANGE would also add to the confusion because of paths being both a source and a destination. See the provided documentation for additional details. New tests are provided with a following commit.

landlock: Fix same-layer rule unions
The original behavior was to check if the full set of requested accesses was allowed by at least a rule of every relevant layer. This didn't take into account requests for multiple accesses and same-layer rules allowing the union of these accesses in a complementary way. As a result, multiple accesses requested on a file hierarchy matching rules that, together, allowed these accesses, but without a unique rule allowing all of them, was illegitimately denied. This case should be rare in practice and it can only be triggered by the path_rename or file_open hook implementations. For instance, if, for the same layer, a rule allows execution beneath /a/b and another rule allows read beneath /a, requesting access to read and execute at the same time for /a/b should be allowed for this layer. This was an inconsistency because the union of same-layer rule accesses was already allowed if requested once at a time anyway. This fix changes the way allowed accesses are gathered over a path walk. To take into account all these rule accesses, we store in a matrix all layer granting the set of requested accesses, according to the handled accesses. To avoid heap allocation, we use an array on the stack which is 2*13 bytes. A following commit bringing the LANDLOCK_ACCESS_FS_REFER access right will increase this size to reach 112 bytes (2*14*4) in case of link or rename actions. Add a new layout1.layer_rule_unions test to check that accesses from different rules pertaining to the same layer are ORed in a file hierarchy. Also test that it is not the case for rules from different layers.

landlock: Reduce the maximum number of layers to 16
The maximum number of nested Landlock domains is currently 64. Because of the following fix and to help reduce the stack size, let's reduce it to 16. This seems large enough for a lot of use cases (e.g. sandboxed init service, spawning a sandboxed SSH service, in nested sandboxed containers). Reducing the number of nested domains may also help to discover misuse of Landlock (e.g. creating a domain per rule). Add and use a dedicated layer_mask_t typedef to fit with the number of layers. This might be useful when changing it and to keep it consistent with the maximum number of layers.

perf session: Fix Intel LBR callstack entries and nr print message
When generating callstack information from branch_stack(Intel LBR), the actual number of callstack entry should be bigger than the number of branch_stack, for example: branch_stack records: B() -> C() A() -> B() converted callstack records should be: C() B() A() though, the number of callstack equals to the number of branch stack plus 1.

Here subtests, "BPF pinning" and "BPF prologue generation" failed and
logs shows clang/llvm is needed. After installing clang, testcase
passes.
Reason on why subtest failure happens though logs has proper debug
information:
Main function __test__bpf calls test_llvm__fetch_bpf_obj by
passing 4th argument as true ( 4th arguments maps to parameter
"force" in test_llvm__fetch_bpf_obj ). But this will cause
test_llvm__fetch_bpf_obj to skip the check for clang/llvm.
Snippet of code part which checks for clang based on
parameter "force" in test_llvm__fetch_bpf_obj:
<<>>
if (!force && (!llvm_param.user_set_param &&
<<>>
Since force is set to "false", test won't get skipped and fails to
compile test case. The BPF code compilation needs clang, So pass the
fourth argument as "false" and also skip the test if reason for return
is "TEST_SKIP"
After the patch:

perf test: Avoid shell test description infinite loop
for_each_shell_test() is already strict in expecting tests to be files and executable. It is sometimes possible when it iterates over all files that it finds one that is executable and lacks a newline character. When this happens the loop never terminates as it doesn't check for EOF. Add the EOF check to make this loop at least bounded by the file size. If the description is returned as NULL then also skip the test.

perf regs x86: Fix arch__intr_reg_mask() for the hybrid platform
The X86 specific arch__intr_reg_mask() is to check whether the kernel
and hardware can collect XMM registers. But it doesn't work on some
hybrid platform.
Without the patch on ADL-N:
$ perf record -I?
available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10
R11 R12 R13 R14 R15
The config of the test event doesn't contain the PMU information. The
kernel may fail to initialize it on the correct hybrid PMU and return
the wrong non-supported information.
Add the PMU information into the config for the hybrid platform. The
same register set is supported among different hybrid PMUs. Checking
the first available one is good enough.
With the patch on ADL-N:
$ perf record -I?
available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10
R11 R12 R13 R14 R15 XMM0 XMM1 XMM2 XMM3 XMM4 XMM5 XMM6 XMM7 XMM8 XMM9
XMM10 XMM11 XMM12 XMM13 XMM14 XMM15

perf test: Fix "all PMU test" to skip hv_24x7/hv_gpci tests on powerpc
"perf all PMU test" picks the input events from "perf list --raw-dump
pmu" list and runs "perf stat -e" for each of the event in the list. In
case of powerpc, the PowerVM environment supports events from hv_24x7
and hv_gpci PMU which is of example format like below:
- hv_24x7/CPM_ADJUNCT_INST,domain=?,core=?/
- hv_gpci/event,partition_id=?/
The value for "?" needs to be filled in depending on system and
respective event. CPM_ADJUNCT_INST needs have core value and domain
value. hv_gpci event needs partition_id. Similarly, there are other
events for hv_24x7 and hv_gpci having "?" in event format. Hence skip
these events on powerpc platform since values like partition_id, domain
is specific to system and event.

ARM:
* Correctly expose GICv3 support even if no irqchip is created
so that userspace doesn't observe it changing pointlessly
(fixing a regression with QEMU)
* Don't issue a hypercall to set the id-mapped vectors when
protected mode is enabled (fix for pKVM in combination with
CPUs affected by Spectre-v3a)
x86: Five oneliners, of which the most interesting two are:
* a NULL pointer dereference on INVPCID executed with
paging disabled, but only if KVM is using shadow paging
* an incorrect bsearch comparison function which could truncate
the result and apply PMU event filtering incorrectly. This one
comes with a selftests update too.

perf stat: Fix and validate CPU map inputs in synthetic PERF_RECORD_STAT events
Stat events can come from disk and so need a degree of validation. They
contain a CPU which needs looking up via CPU map to access a counter.
Add the CPU to index translation, alongside validity checking.

perf build: Fix check for btf__load_from_kernel_by_id() in libbpf
Avi Kivity reported a problem where the __weak
btf__load_from_kernel_by_id() in tools/perf/util/bpf-event.c was being
used and it called btf__get_from_id() in tools/lib/bpf/btf.c that in
turn called back to btf__load_from_kernel_by_id(), resulting in an
endless loop.
Fix this by adding a feature test to check if
btf__load_from_kernel_by_id() is available when building perf with
LIBBPF_DYNAMIC=1, and if not then provide the fallback to the old
btf__get_from_id(), that doesn't call back to btf__load_from_kernel_by_id()
since at that time it didn't exist at all.
Tested on Fedora 35 where we have libbpf-devel 0.4.0 with LIBBPF_DYNAMIC
where we don't have btf__load_from_kernel_by_id() and thus its feature
test fail, not defining HAVE_LIBBPF_BTF__LOAD_FROM_KERNEL_BY_ID:
$ cat /tmp/build/perf-urgent/feature/test-libbpf-btf__load_from_kernel_by_id.make.output

selftests: kvm/x86: Verify the pmu event filter matches the correct event
Add a test to demonstrate that when the guest programs an event select
it is matched correctly in the pmu event filter and not inadvertently
filtered. This could happen on AMD if the high nybble[1] in the event
select gets truncated away only leaving the bottom byte[2] left for
matching.
This is a contrived example used for the convenience of demonstrating
this issue, however, this can be applied to event selects 0x28A (OC
Mode Switch) and 0x08A (L1 BTB Correction), where 0x08A could end up
being denied when the event select was only set up to deny 0x28A.
[1] bits 35:32 in the event select register and bits 11:8 in the event
select.
[2] bits 7:0 in the event select register and bits 7:0 in the event
select.

Add a helper function that creates a pmu event filter given an event list. Currently, a pmu event filter can only be created with the same hard coded event list. Add a way to create one given a different event list. Also, rename make_pmu_event_filter to alloc_pmu_event_filter to clarify it's purpose given the introduction of create_pmu_event_filter.
