Keep thread timer ownership when timer stop races with an in-flight timeout callback, and consume IPC resources only after a waiter is resumed successfully.
Complete ownership cleanup in the generic and RT-Smart channel timeout callbacks. Add deterministic scheduler and LWP regressions for Event, Semaphore, Mailbox, Message Queue, sender, and receiver paths.

Improve the Rust build integration across core, applications, components, and module examples. Fix build failure propagation, target and feature handling, linker flags, example configuration semantics, and add STM32 CI attach coverage.

The original overflow logic used __spm[tm_mon] as the current month's
length when normalizing tm_mday. This produced incorrect dates after
crossing month boundaries and left zero or negative days unnormalized.
Use the difference between adjacent cumulative day offsets with
leap-year handling. Normalize overflow in tm_sec, tm_min, tm_hour,
tm_mday, and tm_mon to keep the affected broken-down fields normalized.
Add regression tests for month boundaries, leap years, large offsets,
zero and negative days, negative time fields, combined overflow, and
boundary carry cases.

* components/dfs: support unix socket nodes
AF_UNIX pathname binding and descriptor passing require DFSv2 socket
nodes and retained open file descriptions across fd tables.
Add socket-node creation for tmpfs and devtmpfs, fd reference helpers,
and socket F_SETFL forwarding.
Impact: DFSv2 socket nodes and descriptor reference handling.
Validation: git diff --cached --check.
* components/net/sal: support local protocol providers
Local IPC protocol families do not have a backing network device.
Store the selected provider in each SAL socket and add a local provider
registry while preserving netdev checks for Internet sockets.
Handle DFSv2 close semantics, socketpair flags, and MSG_CTRUNC for
AF_UNIX integration.
Impact: SAL protocol dispatch for all socket families.
Validation: git diff --cached --check.
* components/lwp: support unix socket messages
Musl AF_UNIX addresses and ancillary data require explicit ABI and
user-memory conversion at the LWP syscall boundary.
Add the musl msghdr layout, bounded address and message copying,
control-message level conversion, and MSG_CTRUNC translation. Correct
receive buffer allocation and copy lengths while handling messages.
Impact: LWP socket syscalls when SAL is enabled.
Validation: git diff --cached --check.
* components/net/af_unix: add local sockets
Add an opt-in AF_UNIX provider for pathname-based local IPC without
a synthetic network device.
Support datagram and stream sockets, blocking and nonblocking I/O,
timeouts, poll, socketpair, and SCM_RIGHTS descriptor passing. Include
bounded Kconfig settings, component documentation, and utest coverage.
Impact: enabled only by RT_USING_AF_UNIX and requires SAL POSIX with
DFSv2.
Validation: git diff --cached --check.
* Fix AF_UNIX CI checks
Apply the repository clang-format rules to the affected source lines.
Suppress the cppcheck false positive for the devtmpfs list iterator.
No functional behavior is changed.
* components/lwp: preserve NULL optional msghdr buffers
When msg_name or msg_control is NULL, keep the kernel pointer NULL
instead of substituting an uninitialized buffer. Reject a NULL control
buffer with a nonzero length as EFAULT.
Impact: LWP sendmsg/recvmsg conversion on MMU targets.
Validation: git diff --cached --check.
* components/net/af_unix: fix poll UAF, namespace leak, and SCM_RIGHTS cycles
Poll only the local wait queue and wake writers from the receiver.
Free namespace entries on detach, and reject AF_UNIX descriptors in
SCM_RIGHTS until cycle collection exists.
Impact: AF_UNIX poll, bind lifetime, and descriptor passing.
Validation: git diff --cached --check.
* components/dfs: add DFSv2 AF_UNIX utest suite
Add opt-in tests under dfs/utest/v2/af_unix for socket nodes, IPC,
poll peer-close, namespace cleanup, and SCM_RIGHTS rejection.
Sources are built only when RT_UTEST_TC_USING_DFS_V2_AF_UNIX and the
selected test groups are enabled.
Impact: DFS utest menu and build; no production AF_UNIX behavior change.
Validation: git diff --cached --check.

* [DM/OFW][PCI] Fix address translation and PCI resource enumeration
Rework OFW address translation to walk nested bus ranges in the correct
direction and cache "ranges" and "dma-ranges" independently. Handle PCI
three-cell addresses without treating the PCI flags cell as part of the
address, and fix CPU-to-DMA and DMA-to-CPU translation across nested
buses.
Fix PCI BAR sizing and assignment by disabling address decoding during
probing, preserving BAR attribute bits, and programming 64-bit BARs
correctly. Add device enable and disable helpers so resources and bus
mastering are enabled before driver probe.
Program bridge memory and prefetch windows while scanning downstream
buses, correctly link child buses into the PCI bus hierarchy, and avoid
unnecessary PCIe link retraining when the link is already active.
Allow host bridges without a device-tree pci-domain property by
allocating unique domains dynamically, while preserving explicit domain
assignments.
Fix MSI and MSI-X IRQ setup, rollback, vector addressing, and affinity
selection.
Add the Raspberry Pi PCI vendor ID for RP1 and other downstream devices.

* [dm][dma] update DMA interface
Extend DMA mapping to honor OFW dma-ranges even
when no reserved memory pool is present,
and add PCI host-bridge DMA-region translation for PCI devices.
Prefer 32-bit-addressable allocations for translated devices,
improve pool allocation fallbacks and synchronization,
and establish a linear mapping for installed DMA pools when possible.

* [dm][dma] fixup PL330 work flow
Fix PL330 channel allocation so device-tree cells

encode burst lengths correctly,
honor transfer direction and non-secure attributes,
and allocate microcode from DMA-coherent memory.

* [DM/Input] Add ADC joystick, keyboard, and touchscreen drivers
Add polling input drivers for ADC-connected joysticks and resistor-
ladder keys. Parse Linux-compatible device-tree bindings, acquire ADC
channels through the IIO framework, and report absolute-axis and key
events.
Add an SPI touchscreen driver for ADS7843, ADS7845, ADS7846, ADS7873,
TSC2046, and XPT2046-compatible controllers. Support pen interrupts,
coordinate and pressure reporting, sample filtering, regulator control,
power management, and common touchscreen properties.
Add an I2C touchscreen driver for Goodix GT9xx controllers with
multi-touch reporting, GPIO-based reset and address selection, interrupt
handling with polling fallback, regulator control, panel configuration,
and alternate-address recovery.
Adapt the drivers to the RT-Thread device model and input framework,
following the corresponding Linux input drivers and device-tree
bindings.

skip redundant gate toggles and hardware programming when
the target is already active, and fix error handling for parent-clock allocation failures.

rt_data_queue_pop() holds the data queue spinlock while updating the ring
state, then calls rt_data_queue_len(). The length function tries to acquire
the same non-recursive spinlock again, causing an SMP deadlock when a pop
leaves the queue non-empty.
Add a private _data_queue_len_nolock() helper for callers which already hold
the queue lock. Keep the public rt_data_queue_len() protected by one spinlock
acquisition.
This does not change the public API, ABI, queue state transitions, low-water
mark wakeups, or event callback behavior.
Tested on a four-core Spacemit K1 with cyclic HDMI playback and by building the
SMP QEMU Virt64 RISC-V BSP with generic audio, Intel HDA and VirtIO Sound.

sys_select() passed the raw user-space timeout pointer straight
through to select(), unlike readfds/writefds/exceptfds which are
all validated with lwp_user_accessable() and copied into kernel
memory first. A malicious or buggy user thread could pass a
timeout pointing at unmapped or otherwise invalid memory, which
select() would then dereference directly (timeout->tv_sec /
timeout->tv_usec) without any check, from kernel context.
Validate and copy it into a kernel-local struct timeval the same
way the fd_set arguments already are, before it reaches select().
Fixes #10298
