DAMON_STAT updates 'enabled' parameter value, which represents the running
status of its kdamond, when the user explicitly requests start/stop of the
kdamond. The kdamond can, however, be stopped even if the user explicitly
requested the stop, if ctx->regions_score_histogram allocation failure at
beginning of the execution of the kdamond. Hence, if the kdamond is
stopped by the allocation failure, the value of the parameter can be
stale.

Users could show the stale value and be confused. The problem will only
rarely happen in real and common setups because the allocation is arguably
too small to fail. Also, unlike the similar bugs that are now fixed in
DAMON_RECLAIM and DAMON_LRU_SORT, kdamond can be restarted in this case,
because DAMON_STAT force-updates the enabled parameter value for user
inputs. The bug is a bug, though.

The issue stems from the fact that there are multiple events that can
change the status, and following all the events is challenging.
Dynamically detect and use the fresh status for the parameters when those
are requested.

The issue was dicovered [1] by Sashiko.

DAMON_LRU_SORT updates 'enabled' and 'kdamond_pid' parameter values, which
represents the running status of its kdamond, when the user explicitly
requests start/stop of the kdamond. The kdamond can, however, be stopped
in events other than the explicit user request in the following three
events.

1. ctx->regions_score_histogram allocation failure at beginning of the
execution,
2. damon_commit_ctx() failure due to invalid user input, and
3. damon_commit_ctx() failure due to its internal allocation failures.

Hence, if the kdamond is stopped by the above three events, the values of
the status parameters can be stale. Users could show the stale values and
be confused. This is already bad, but the real consequence is worse.
DAMON_LRU_SORT avoids unnecessary damon_start() and damon_stop() calls
based on the 'enabled' parameter value. And the update of 'enabled'
parameter value depends on the damon_start() and damon_stop() call
results. Hence, once the kdamond has stopped by the unintentional events,
the user cannot restart the kdamond before the system reboot. For
example, the issue can be reproduced via below steps.

# cd /sys/module/damon_lru_sort/parameters
#
# # start DAMON_LRU_SORT
# echo Y > enabled
# ps -ef | grep kdamond

Patch series "mm/damon/modules: detect and use fresh status", v3.

DAMON modules including DAMON_RECLAIM, DAMON_LRU_SORT and DAMON_STAT
commonly expose the kdamond running status via their parameters. Under
certain scenarios including wrong user inputs and memory allocation
failures, those parameter values can be stale. It can confuse users. For
DAMON_RECLAIM and DAMON_LRU_SORT, it even makes the kdamond unable to be
restarted before the system reboot.

The problem comes from the fact that there are multiple events for the
status changes and it is difficult to follow up all the scenarios. Fix
the issue by detecting and using the status on demand, instead of using a
cached status that is difficult to be updated.

Patches 1-3 fix the bugs in DAMON_RECLAIM, DAMON_LRU_SORT and DAMON_STAT
in the order.

Several of the mm selftests made use of /proc/pid/mem as part of their
operation but we do not specify this in the config fragment for them, at
least mkdirty and ksm_functional_tests have this requirement.

This has been working fine in practice since PROC_MEM_ALWAYS_FORCE was the
default setting but commit 599bbba5a36f ("proc: make PROC_MEM_FORCE_PTRACE
the Kconfig default") that is no longer the case, meaning that tests run
on kernels built based on defconfigs have started having the new more
restrictive default and failing. Add PROC_MEM_ALWAYS_FORCE to the config
fragment for the mm selftests.

Thanks to Aishwarya TCV for spotting the issue and identifying the commit
that introduced it.

damon_sysfs_quot_goal->path can be read and written by users, via DAMON
sysfs 'path' file. It can also be indirectly read, for the parameters
{on,off}line committing to DAMON. The reads for parameters committing are
protected by damon_sysfs_lock to avoid the sysfs files being destroyed
while any of the parameters are being read. But the user-driven direct
reads and writes are not protected by any lock, while the write is
deallocating the path-pointing buffer. As a result, the readers could
read the already freed buffer (user-after-free). Note that the user-reads
don't race when the same open file is used by the writer, due to kernfs's
open file locking. Nonetheless, doing the reads and writes with separate
open files would be common. Fix it by protecting both the user-direct
reads and writes with damon_sysfs_lock.

When the user requests a total hugetlb CMA size without per-node
specification, hugetlb_cma_reserve() computes per_node from
hugetlb_cma_size and the number of nodes that have memory

per_node = DIV_ROUND_UP(hugetlb_cma_size,
nodes_weight(hugetlb_bootmem_nodes));

The reservation loop later computes

size = round_up(min(per_node, hugetlb_cma_size - reserved),
PAGE_SIZE << order);

So the actually reserved per_node size is multiple of (PAGE_SIZE <<
order), but the logged per_node is not rounded up, so it may be smaller
than the actual reserved size.

For example, as the existing comment describes, if a 3 GB area is
requested on a machine with 4 NUMA nodes that have memory, 1 GB is
allocated on the first three nodes, but the printed log is

hugetlb_cma: reserve 3072 MiB, up to 768 MiB per node

Round per_node up to (PAGE_SIZE << order) before logging so that the
printed log always matches the actual reserved size. No functional change
to the actual reservation size, as the following case analysis shows

1. remaining (hugetlb_cma_size - reserved) >= rounded per_node
- AS-IS: min() picks unrounded per_node;
round_up() returns rounded per_node
- TO-BE: min() picks rounded per_node;
round_up() returns rounded per_node (no-op)
2. remaining < unrounded per_node
- AS-IS: min() picks remaining;
round_up() returns round_up(remaining)
- TO-BE: min() picks remaining;
round_up() returns round_up(remaining)
3. unrounded per_node <= remaining < rounded per_node
- AS-IS: min() picks unrounded per_node;
round_up() returns rounded per_node
- TO-BE: min() picks remaining;
round_up() returns round_up(remaining) equals rounded per_node

The pattern "include/linux/page[-_]*" matches every file that starts with
"page", because it's a regex and not a glob (so it has the meaning of
include/linux/page + match [-_] 0+ times).

Fix it up into a more regex-correct expression. Doing so reduces CC's
drastically in patches that touch pagemap.h (which is maintained as part
of PAGE CACHE).

As a side-effect, move linux/pageblock-flags.h explicitly under PAGE
ALLOCATOR.

The mmap_prepare hook functionality includes the ability to invoke
mmap_prepare() from the mmap() hook of existing 'stacked' drivers, that is
ones which are capable of calling the mmap hooks of other drivers/file
systems (e.g. overlayfs, shm).

As part of the mmap_prepare action functionality, we deal with errors by
unmapping the VMA should one arise. This works in the usual mmap_prepare
case, as we invoke this action at the last moment, when the VMA is
established in the maple tree.

However, the mmap() hook passes a not-fully-established VMA pointer to the
caller (which is the motivation behind the mmap_prepare() work), which is
detached.

So attempting to unmap a VMA in this state will be problematic, with the
most obvious symptom being a warning in vma_mark_detached(), because the
VMA is already detached.

It's also unncessary - the mmap() handler will clean up the VMA on error.

So to fix this issue, this patch propagates whether or not an mmap action
is being completed via the compatibility layer or directly.

If the former, then we do not attempt VMA cleanup, if the latter, then we
do.

This patch also updates the userland VMA tests to reflect the change.

The proactive nr_dirty > gdtc->bg_thresh check in balance_dirty_pages()
only checks the global dirty threshold to start background writeback while
the writer is still free-running, but for strictlimit BDIs (eg fuse), the
per-wb dirty count can exceed the per-wb background threshold while the
global threshold is not yet exceeded, so background writeback for this
case never gets proactively started.

Add a per-wb threshold check for strictlimit BDIs so that background
writeback is started when wb_dirty exceeds wb_bg_thresh, which drains
dirty pages before the writer hits the throttle wall, matching the
proactive behavior that the global check provides for non-strictlimit
BDIs.

Fix two error handling issues in kho_add_subtree(), where it doesn't
handle the error path correctly.

1. If fdt_setprop() fails after the subnode has been created, the
subnode is not removed. This leaves an incomplete node in the FDT
(missing "preserved-data" or "blob-size" properties).

2. The fdt_setprop() return value (an FDT error code) is stored
directly in err and returned to the caller, which expects -errno.

Fix both by storing fdt_setprop() results in fdt_err, jumping to a new
out_del_node label that removes the subnode on failure, and only setting
err = 0 on the success path, otherwise returning -ENOMEM (instead of
FDT_ERR_ errors that would come from fdt_setprop).

No user-visible changes. This patch fixes error handling in the KHO
(Kexec HandOver) subsystem, which is used to preserve data across kexec
reboots. The fix only affects a rare failure path during kexec
preparation — specifically when the kernel runs out of space in the
Flattened Device Tree buffer while registering preserved memory regions.

In the unlikely event that this error path was triggered, the old code
would leave a malformed node in the device tree and return an incorrect
error code to the calling subsystem, which could lead to confusing log
messages or incorrect recovery decisions. With this fix, the incomplete
node is properly cleaned up and the appropriate errno value is propagated,
this error code is not returned to the user.

When session allocation fails during deserialization, the global 'err'
variable was not updated before returning. This caused subsequent calls
to luo_session_deserialize() to incorrectly report success.

Ensure 'err' is set to the error code from PTR_ERR(session). This ensures
that an error is correctly returned to userspace when it attempts to open
/dev/liveupdate in the new kernel if deserialization failed.

Commit 4c5d3365882d ("mm/vmalloc: allow to set node and align in
vrealloc") added the ability to force a new allocation if the current
pointer is on the wrong NUMA node, or if an alignment constraint is not
met, even if the user is shrinking the allocation.

On this path (need_realloc), the code allocates a new object of 'size'
bytes and then memcpy()s 'old_size' bytes into it. If the request is to

On Raspberry Pi 3B, the VEC clock is used by the VideoCore firmware
display driver, which remains active until the vc4 driver loads and
sends NOTIFY_DISPLAY_DONE. If this clock is disabled during boot, a bus
lockup happens and the firmware becomes unresponsive, causing a complete
system lockup.

Mark the VEC clock with CLK_IGNORE_UNUSED so it survives the unused
clock disablement and remains available until the vc4 driver takes over
display management.

The fixdep hostprog may be built multiple times during a single build.
Once during the configuration phase and later during the regular phase.
As only the regular build phase respects CONFIG_WERROR / W=e, the
compiler flags might change between the phases, leading to rebuilds.

Example, the rebuilds will happen twice on each invocation of the build:

$ make allyesconfig prepare
make[1]: Entering directory '/tmp/deleteme'
HOSTCC scripts/basic/fixdep
#
# No change to .config
#
HOSTCC scripts/basic/fixdep
DESCEND objtool
INSTALL libsubcmd_headers
make[1]: Leaving directory '/tmp/deleteme'

Fix the compilation flags used for scripts/basic/ before
scripts/Makefile.warn is evaluated to stop CONFIG_WERROR / W=e
influencing the fixdep build to avoid the spurious rebuilds.

The driver currently supports generating BCLK. There are systems which
require generation of MCLK instead. Register new MCLK clock and handle
clock-cells = <1> to differentiate between BCLK and MCLK. In case of a
legacy system with clock-cells = <0>, the driver behaves as before, i.e.
always returns BCLK.

Note that it is not possible re-use the current SAI audio driver to
generate MCLK and correctly enable and disable the MCLK.

If SAI (audio driver) is used to control the MCLK enablement, then MCLK
clock is not always enabled, and it is not necessarily enabled when the
codec may need the clock to be enabled. There is also no way for the
codec node to specify phandle to clock provider in DT, because the SAI
(audio driver) is not clock provider.

If SAI (clock driver) is used to control the MCLK enablement, then MCLK
clock is enabled when the codec needs the clock enabled, because the
codec is the clock consumer and the SAI (clock driver) is the clock
provider, and the codec driver can request the clock to be enabled when
needed. There is also the usual phandle to clock provider in DT, because
the SAI (clock driver) is clock provider.

clk_core_populate_parent_map() currently prefers the parent names over
the parent data and hws, so this isn't a problem at the moment. If that
ordering ever changed in the future, then this could lead to some
unexpected crashes. Let's just go ahead and make sure that the struct
clk_init_data is initialized to zero as a good practice.

Commit e2c318225ac1 ("kbuild: deb-pkg: add
pkg.linux-upstream.nokernelheaders build profile") changed how
install-extmod-build gets called, making it always rebuild the host
programs below scripts/ if HOSTCC wasn't specified with its full triplet
on the make command line. That is, apparently, needed to fix up commit
f1d87664b82a ("kbuild: cross-compile linux-headers package when
possible") for cross-compiles. However, in the much more common case of
non-cross-compile builds this will lead to unnecessary rebuilding of
host tools including gcc plugins. This, in turn, will lead to a full
kernel rebuild on the next 'make bindeb-pkg' which is unfortunate.

Avoid that by only triggering the rebuild of host tools for actual
cross-compile builds.

Commit 795cda8338ea ("rtc: interface: Fix long-standing race when setting
alarm") exposed an issue where the rtc-abx80x driver does not clear the
alarm feature bit, but instead relies on the set_alarm operation to return
invalid.

For example, when a RTC_UIE_ON ioctl is handled, it should abort at the
feature validation. Instead, it proceeds to the rtc_timer_enqueue(),
which used to return an error from the set_alarm call. However,
following the race condition handling, which likely should not be
discarding predecing errors, a success condition is returned to the
ioctl() caller. This results in (for example):
hwclock: select() to /dev/rtc0 to wait for clock tick timed out

Notwithstanding the validity of the race condition handling, if an interrupt
wasn't specified, or could not be attached, the driver should clear the
alarm feature bit.

Pull probes fixes from Masami Hiramatsu:

- Avoid crash when rmmod/insmod after ftrace killed

This fixes a kernel crash caused by kprobes on the symbol in a module
which is unloaded after ftrace_kill() is called.

- Remove unneeded warnings from __arm_kprobe_ftrace()

Remove unneeded WARN messages which can be triggered if the kprobe is
using ftrace and it fails to enable the ftrace. Since kprobes
correctly handle such failure, we don't need to warn it.

On current firmware versions, RPI_FIRMWARE_SET_CLOCK_STATE doesn't
actually power off the clock. To achieve meaningful power savings, the
clock rate must be set to the minimum before disabling. This might be
fixed in future firmware releases.

Rather than pushing rate management to clock consumers, handle it
directly in the clock framework's prepare/unprepare callbacks. In
unprepare, set the rate to the minimum before disabling the clock.
In prepare, for clocks marked with `maximize` (currently v3d),
restore the rate to the maximum after enabling.
