Some libc's like musl libc don't provide execinfo.h since it's not part of
POSIX. In order to fix compilation on musl, only include execinfo.h if
available (HAVE_BACKTRACE_SUPPORT)
This was discovered with c104c16073b7 ("Kunit to check the longest symbol
length") which starts to include linux/kallsyms.h with Alpine Linux'
configs.

assertions that have already helped discover weird behavior our
outright bugs.

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembler code, __ASSEMBLY__ is a macro
that only gets defined by the Makefiles in the kernel. This is bad
since macros starting with two underscores are names that are reserved
by the C language. It can also be very confusing for the developers
when switching between userspace and kernelspace coding, or when
dealing with uapi headers that rather should use __ASSEMBLER__ instead.
So let's now standardize on the __ASSEMBLER__ macro that is provided
by the compilers.
This is almost a completely mechanical patch (done with a simple
"sed -i" statement), with one comment tweaked manually in the
arch/loongarch/include/asm/cpu.h file (it was missing the trailing
underscores).

validate_addr() checks whether the address returned by mmap() lies in the
low or high VA space, according to whether a high addr hint was passed or
not. The fix commit mentioned below changed the code in such a way that
this function will always return failure when passed high_addr == 1; addr
will be >= HIGH_ADDR_MARK always, we will fall down to "if (addr >
HIGH_ADDR_MARK)" and return failure. Fix this.

The `name` field in `obj->externs` points into the BTF data at initial
open time. However, some functions may invalidate this after opening and
before loading (e.g. `bpf_map__set_value_size`), which results in
pointers into freed memory and undefined behavior.
The simplest solution is to simply `strdup` these strings, similar to
the `essent_name`, and free them at the same time.
In order to test this path, the `global_map_resize` BPF selftest is
modified slightly to ensure the presence of an extern, which causes this
test to fail prior to the fix. Given there isn't an obvious API or error
to test against, I opted to add this to the existing test as an aspect
of the resizing feature rather than duplicate the test.

Commit 869c788909b9 ("selftests: harness: Stop using setjmp()/longjmp()")
changed the harness structure. For some unknown reason, two build warnings
occur to the iommufd selftest:
iommufd.c: In function ‘wrapper_iommufd_mock_domain_all_aligns’:
iommufd.c:1807:17: warning: ‘mfd’ may be used uninitialized in this function
1807 | close(mfd);

iommufd.c:1767:13: note: ‘mfd’ was declared here

iommufd.c: In function ‘wrapper_iommufd_mock_domain_all_aligns_copy’:

1870 | close(mfd);
| ^~~~~~~~~~
iommufd.c:1819:13: note: ‘mfd’ was declared here
1819 | int mfd;
| ^~~
All the mfd have been used in the variant->file path only, so it's likely
a false alarm.
FWIW, the commit mentioned above does not cause this, yet it might affect
gcc in a certain way that resulted in the warnings. It is also found that
ading a dummy setjmp (which doesn't make sense) could mute the warnings:
https://lore.kernel.org/all/aEi8DV+ReF3v3Rlf@nvidia.com/
The job of this selftest is to catch kernel bug, while such warnings will
unlikely disrupt its role. Mute the warning by force initializing the mfd
and add an ASSERT_GT().

The hugepage test cases of iommufd_dirty_tracking have the 64MB and 128MB
coverages. Both of them are smaller than the default hugepage size 512MB,
when CONFIG_PAGE_SIZE_64KB=y. However, these test cases have a variant of
using huge pages, which would mmap(MAP_HUGETLB) using these smaller sizes
than the system hugepag size. This results in the kernel aligning up the
smaller size to 512MB. If a memory was located between the upper 64/128MB
size boundary and the hugepage 512MB boundary, it would get wiped out:
https://lore.kernel.org/all/aEoUhPYIAizTLADq@nvidia.com/
Given that this aligning up behavior is well documented, we have no choice
but to allocate a hugepage aligned size to avoid this unintended wipe out.
Instead of relying on the kernel's internal force alignment, pass the same
size to posix_memalign() and map().
Also, fix the FIXTURE_TEARDOWN() misusing munmap() to free the memory from
posix_memalign(), as munmap() doesn't destroy the allocator meta data. So,
call free() instead.

When btf_dump__new() fails to allocate memory for the internal hashmap
(btf_dump->type_names), it returns an error code. However, the cleanup
function btf_dump__free() does not check if btf_dump->type_names is NULL
before attempting to free it. This leads to a null pointer dereference

"20 hotfixes. 7 are cc:stable and the remainder address post-6.15
issues or aren't considered necessary for -stable kernels. Only 4 are
for MM.
- The series `Revert "bcache: update min_heap_callbacks to use
default builtin swap"' from Kuan-Wei Chiu backs out the author's
recent min_heap changes due to a performance regression.
A fix for this regression has been developed but we felt it best to
go back to the known-good version to give the new code more bake
time.
- A lot of MAINTAINERS maintenance.
I like to get these changes upstreamed promptly because they can't
break things and more accurate/complete MAINTAINERS info hopefully
improves the speed and accuracy of our responses to submitters and

The coredump.socket_detect_userspace_client test occasionally fails:
# RUN coredump.socket_detect_userspace_client ...
# stackdump_test.c:500:socket_detect_userspace_client:Expected 0 (0) != WIFEXITED(status) (0)
# socket_detect_userspace_client: Test terminated by assertion
# FAIL coredump.socket_detect_userspace_client
not ok 3 coredump.socket_detect_userspace_client
because there is no guarantee that client's write() happens before server's
close(). The client gets terminated SIGPIPE, and thus the test fails.
Add a read() to server to make sure server's close() doesn't happen before
client's write().

CONFIG_UPROBES is enabled by CONFIG_UPROBE_EVENTS, which gets enabled by
CONFIG_FTRACE. Therefore add these configs to selftests/mm/config so that
CI systems can include this config in the kernel build. To be completely
safe, add CONFIG_PROFILING too, to enable the dependency chain
PROFILING -> PERF_EVENTS -> UPROBE_EVENTS -> UPROBES.

The multi message support loosened the connection between the request
and response handling, as we can now submit multiple requests before
we start processing responses. Passing the attr set to NlMsgs decoding
no longer makes sense (if it ever did), attr set may differ message
by messsage. Isolate the part of decoding responsible for attr-set
specific interpretation and call it once we identified the correct op.
Without this fix performing SET operation on an ethtool socket, while
being subscribed to notifications causes:
# File "tools/net/ynl/pyynl/lib/ynl.py", line 1096, in _op
# Exception| return self._ops(ops)[0]
# Exception| ~~~~~~~~~^^^^^
# File "tools/net/ynl/pyynl/lib/ynl.py", line 1040, in _ops
# Exception| nms = NlMsgs(reply, attr_space=op.attr_set)
# Exception| ^^^^^^^^^^^
The value of op we use on line 1040 is stale, it comes form the previous
loop. If a notification comes before a response we will update op to None
and the next iteration thru the loop will break with the trace above.

BPF_MAP_TYPE_LRU_HASH can recycle most recent elements well before the
map is full, due to percpu reservations and force shrink before
neighbor stealing. Once a CPU is unable to borrow from the global map,
it will once steal one elem from a neighbor and after that each time
flush this one element to the global list and immediately recycle it.
Batch value LOCAL_FREE_TARGET (128) will exhaust a 10K element map
with 79 CPUs. CPU 79 will observe this behavior even while its
neighbors hold 78 * 127 + 1 * 15 == 9921 free elements (99%).
CPUs need not be active concurrently. The issue can appear with
affinity migration, e.g., irqbalance. Each CPU can reserve and then
hold onto its 128 elements indefinitely.
Avoid global list exhaustion by limiting aggregate percpu caches to
half of map size, by adjusting LOCAL_FREE_TARGET based on cpu count.
This change has no effect on sufficiently large tables.
Similar to LOCAL_NR_SCANS and lru->nr_scans, introduce a map variable
lru->free_target. The extra field fits in a hole in struct bpf_lru.
The cacheline is already warm where read in the hot path. The field is
only accessed with the lru lock held.

Namhyung Kim reported:
I've updated the perf-tools-next to v6.16-rc1 and found a build error
like below on alpine linux 3.18.
In file included from bench/futex.c:6:
/usr/include/sys/prctl.h:88:8: error: redefinition of 'struct prctl_mm_map'
88 | struct prctl_mm_map {
| ^~~~~~~~~~~~
In file included from bench/futex.c:5:
/linux/tools/include/uapi/linux/prctl.h:134:8: note: originally defined here
134 | struct prctl_mm_map {
| ^~~~~~~~~~~~
make[4]: *** [/linux/tools/build/Makefile.build:86: /build/bench/futex.o] Error 1
git bisect says it's the first commit introduced the failure.
So both /usr/include/sys/prctl.h and /linux/tools/include/uapi/linux/prctl.h
provide struct prctl_mm_map but their include guard must be different.
/usr/include/sys/prctl.h provided by glibc contains the
prctl() declaration. It includes also linux/prctl.h.
The /usr/include/sys/prctl.h on alpine linux is different. This is
probably coming from musl. It contains the PR_* definition and the
prctl() declaration. So it clashes here because now the one struct is
available twice.
The man page for prctl(2) says:
| #include <linux/prctl.h> /* Definition of PR_* constants */
| #include <sys/prctl.h>
so musl doesn't follow this.
So don't include linux/prctl.h explicitely and add some new defines
needed if they aren't available.

861c6b1185fbb2e3 ("x86/platform/amd: Add standard header guards to <asm/amd/ibs.h>")
A small change to tools/perf/check-headers.sh was made to cope with the
move of this header done in:
3846389c03a85188 ("x86/platform/amd: Move the <asm/amd-ibs.h> header to <asm/amd/ibs.h>")
That don't result in any changes in the tools, just address this perf

LSM hooks such as security_path_mknod() and security_inode_rename() have
access to newly allocated negative dentry, which has NULL d_inode.
Therefore, it is necessary to do the NULL pointer check for d_inode.
Also add selftests that checks the verifier enforces the NULL pointer
check.

Pull x86 fixes from Dave Hansen:
"This is a pretty scattered set of fixes. The majority of them are
further fixups around the recent ITS mitigations.
The rest don't really have a coherent story:
- Some flavors of Xen PV guests don't support large pages, but the
set_memory.c code assumes all CPUs support them.
Avoid problems with a quick CPU feature check.
- The TDX code has some wrappers to help retry calls to the TDX
module. They use function pointers to assembly functions and the
compiler usually generates direct CALLs. But some new compilers,
plus -Os turned them in to indirect CALLs and the assembly code was
not annotated for indirect calls.
Force inlining of the helper to fix it up.
- Last, a FRED issue showed up when single-stepping. It's fine when
using an external debugger, but was getting stuck returning from a
SIGTRAP handler otherwise.
Clear the FRED 'swevent' bit to ensure that forward progress is
made"
* tag 'x86_urgent_for_6.16-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
Revert "mm/execmem: Unify early execmem_cache behaviour"
x86/its: explicitly manage permissions for ITS pages
x86/its: move its_pages array to struct mod_arch_specific
x86/Kconfig: only enable ROX cache in execmem when STRICT_MODULE_RWX is set
x86/mm/pat: don't collapse pages without PSE set
x86/virt/tdx: Avoid indirect calls to TDX assembly functions
selftests/x86: Add a test to detect infinite SIGTRAP handler loop

That cause no changes to tooling as it doesn't include a new MSR to be
captured by the tools/perf/trace/beauty/tracepoints/x86_msr.sh script.
