 ## Testing

-*This section should provide a detailed description of what you did
-to verify your changes work and do not break existing code.*
+*Update this section with details on how did you verify the change,
+ what Host was used for build (OS, CPU, compiler, ..), what Target was
+ used for verification (arch, board:config, ..), etc. Providing build
+ and runtime logs from before and after change is highly appreciated.*

-*Please provide information about your host machine, the board(s) you
-tested your changes on, and how you tested. Logs should be included.*

-*For example, when changing something in the core OS functions, you
-may want to run the OSTest application to verify that there are no
-regressions. Changes to ADC code may warrant running the `adc`
-example. Adding a new uORB driver may require that you run
-`uorb_listener` to verify correct operation.*
-
-*Pure documentation changes can just be tested with `make html`
-(see docs) and verification of the correct format in your
-browser.*
-
-**_PRs without testing information will not be accepted. We will
-request test logs._**

+* [#16499](https://github.com/apache/nuttx/pull/16499) [BREAKING] fs/vfs: Separate file descriptors from file descriptions
+
+This PR is a rework of the NuttX file descriptor implementation. The goal is two-fold:
+
+Improve POSIX compliance. The old implementation tied file description
+to inode only, not the file struct. POSIX however dictates otherwise.
+Fix a bug with descriptor duplication (dup2() and dup3()). There is
+an existing race condition with this POSIX API that currently results
+in a kernel side crash.
+The crash occurs when a partially open / closed file descriptor is
+duplicated. The reason for the crash is that even if the descriptor is
+closed, the file might still be in use by the kernel (due to e.g. ongoing
+write to file). The open file data is changed by file_dup3() and this
+causes a crash in the device / drivers themselves as they lose access to
+the inode and private data.
+
+The fix is done by separating struct file into file and file descriptor
+structs. The file struct can live on even if the descriptor is closed,
+fixing the crash. This also fixes the POSIX issue, as two descriptors
+can now point to the same file.
+
+The implementation of this PR is based on the modifications made in #16361.
+Thank you @pussuw
+
+DEPENDS ON: apache/nuttx-apps#3091
+
+IMPACT
+
+Remove the FS_REFCOUNT config because reference counting is a very necessary feature
+that is required in many scenarios to ensure stability.
+Rename the functions fs_getfilep, fs_putfilep, and fs_reffilep to file_get, file_put,
+and file_ref respectively, to unify the naming convention to file_xxx, such as file_open,
+ file_ioctl, etc.
+Introduce a new fd (file descriptor) structure. If multiple file descriptors (fds) are in
+ a dup relationship, they can share the same file entity to implement the dup functionality.
+Modify the functions nx_close_from_tcb, nx_open_from_tcb, nx_dup2_from_tcb,
+and nx_dup3_from_tcb to fdlist_open, fdlist_close, fdlist_dup2, and fdlist_dup3 respectively,
+ to uniformly operate on file descriptors using fdlist.

 ``ntpclient`` NTP client
 ========================

-The NTP (Network Time Protocol) client is a network utility that synchronizes
-the system clock with time servers over the Internet. This implementation
-provides a minimal but functional NTP client for NuttX.
-
-What is NTP?
-============
-
-The Network Time Protocol (NTP) is a networking protocol designed to
-synchronize clocks of computer systems over packet-switched, variable-latency
-data networks. NTP is one of the oldest Internet protocols still in use,
-originally designed by David L. Mills of the University of Delaware.
-
-Key features of NTP:
-
- **High Precision**: NTP can achieve sub-millisecond accuracy on local area
-  networks and typically 10-100 millisecond accuracy over the Internet
- **Robust Algorithm**: Uses sophisticated algorithms to filter out network
-  jitter and select the best time sources
- **Hierarchical Structure**: Uses a stratum system where stratum 0 devices
-  are atomic clocks, stratum 1 servers sync with stratum 0, and so on
- **Fault Tolerance**: Can handle multiple time sources and automatically
-  switch between them
-
-NTP Protocol Overview
-=====================
-
-NTP uses UDP port 123 and follows a client-server model. The protocol
-exchanges timestamps to calculate:
-
- **Offset**: The difference between the client's clock and the server's clock
- **Delay**: The round-trip network delay
- **Dispersion**: The maximum error due to clock frequency tolerance
-
-The NTP packet format (version 3) includes:
-
- **Leap Indicator**: Warns of an impending leap second
- **Version Number**: NTP version (3 in this implementation)
- **Mode**: Client, server, broadcast, etc.
- **Stratum**: Clock level (0-15)
- **Poll Interval**: Maximum interval between successive messages
- **Precision**: Clock precision
- **Root Delay/Dispersion**: Total delay and dispersion to the reference clock
- **Reference Identifier**: Identifies the reference source
- **Reference Timestamp**: Time when the system clock was last set
- **Originate Timestamp**: Time when the request departed the client
- **Receive Timestamp**: Time when the request arrived at the server
- **Transmit Timestamp**: Time when the reply departed the server
-
-Implementation Details
-======================
-
-The NuttX NTP client implementation consists of several key components:
-
-Source Code Structure
---------------------
-
-**ntpclient.c** - Main implementation file containing:
-
- **Daemon Management**: Functions to start, stop, and manage the NTP daemon
- **Time Synchronization**: Core algorithms for calculating clock offset and delay
- **Network Communication**: UDP socket handling and NTP packet exchange
- **Sample Collection**: Gathering multiple time samples for statistical filtering
-
-**ntpv3.h** - NTP version 3 packet format definitions:
-
- **ntp_datagram_s**: Complete NTP packet structure
- **ntp_timestamp_s**: 64-bit NTP timestamp format
- **Protocol Constants**: NTP version, modes, and stratum definitions
-
-Key Functions
-------------
-
- **ntpc_start_with_list()**: Starts the NTP daemon with a list of servers
- **ntpc_start()**: Starts the NTP daemon with default configuration
- **ntpc_stop()**: Stops the running NTP daemon
- **ntpc_status()**: Retrieves current synchronization status and samples
- **ntpc_daemon()**: Main daemon loop that:
-
-  - Connects to configured NTP servers
-  - Sends NTP requests and processes responses
-  - Calculates clock offset and delay
-  - Applies time corrections to the system clock
-  - Continues polling at configured intervals
-
- **ntpc_get_ntp_sample()**: Performs a single NTP transaction:
-
-  - Creates UDP socket to NTP server
-  - Sends NTP request packet with current timestamp
-  - Receives and validates NTP response
-  - Calculates offset and delay using NTP algorithms
-
- **ntpc_calculate_offset()**: Implements the NTP clock filter algorithm
-
-  - Uses four timestamps, calculates offset and delay
-  - Applies statistical filtering to reduce jitter
-
- **ntpc_settime()**: Applies time correction to system clock:
-
-  - Uses calculated offset to adjust system time
-  - Handles both positive and negative time adjustments
-  - Maintains monotonic clock consistency
-
-Configuration Options
-=====================
-
-The NTP client can be configured through Kconfig options:
-
- **CONFIG_NETUTILS_NTPCLIENT_SERVER**: List of NTP server hostnames
- **CONFIG_NETUTILS_NTPCLIENT_PORTNO**: NTP server port (default: 123)
- **CONFIG_NETUTILS_NTPCLIENT_STACKSIZE**: Daemon task stack size
- **CONFIG_NETUTILS_NTPCLIENT_SERVERPRIO**: Daemon task priority
- **CONFIG_NETUTILS_NTPCLIENT_STAY_ON**: Keep polling continuously
- **CONFIG_NETUTILS_NTPCLIENT_POLLDELAYSEC**: Polling interval in seconds
- **CONFIG_NETUTILS_NTPCLIENT_NUM_SAMPLES**: Number of samples for filtering
- **CONFIG_NETUTILS_NTPCLIENT_TIMEOUT_MS**: Network timeout in milliseconds
-
-Usage
-=====
-
-The NTP client is typically used through the system commands:
-
-.. note:: The NTP client functionality requires enabling the :code:`SYSTEM_NTPC` option in your configuration.
-    Make sure to select this option in menuconfig or your Kconfig fragment before building.
-
- **ntpcstart**: Start the NTP daemon
- **ntpcstop**: Stop the NTP daemon
- **ntpcstatus**: Display synchronization status
-
-Example workflow:
-
-1. Configure network connectivity
-2. Start NTP client: ``ntpcstart``
-3. Check status: ``ntpcstatus``
-4. Verify time: ``date`` command
-5. Stop when needed: ``ntpcstop``
-
-The client will automatically:
- Connect to configured NTP servers
- Exchange time information
- Calculate and apply clock corrections
- Continue periodic synchronization
-
-Limitations
-===========
-
-This is a minimal NTP client implementation with some limitations:
-
- **No Authentication**: Does not support NTP authentication (MD5/SHA1)
- **Basic Filtering**: Uses simple statistical filtering, not full NTP algorithms
- **Single Reference**: Does not implement full NTP reference clock selection
- **No Leap Seconds**: Does not handle leap second announcements
- **Limited Error Handling**: Basic error recovery and retry mechanisms
-
-Despite these limitations, the implementation provides sufficient accuracy
-for most embedded applications requiring network time synchronization.
-
-Dependencies
-============
-
-The NTP client requires:
-
- **CONFIG_NET**: Network support
- **CONFIG_NET_UDP**: UDP protocol support
- **CONFIG_NET_SOCKOPTS**: Socket options support
- **CONFIG_LIBC_NETDB**: DNS resolution (recommended)
- **CONFIG_HAVE_LONG_LONG**: 64-bit integer support
-
-For best results, ensure:
- Stable network connectivity
- Access to reliable NTP servers
- Sufficient system resources for daemon operation
+This is a fragmentary NTP client. It neither well-tested nor
+mature nor complete at this point in time.

 ``ntpc`` NTP Daemon Commands
 ============================
-
-This example demonstrates how to use the NTP client to synchronize system time
-and retrieve the current time and date. It uses the Network Time Protocol (NTP)
-to provide accurate time synchronization.
-
-Description
-----------
-
-The ntpc example:
-
- Uses the NTP client library to synchronize system time
-
- Connects to NTP servers (default: pool.ntp.org)
-
- Starts the NTP client in the background for continuous synchronization
-
- Provides commands to check status and stop the NTP client
-
- Allows management of the NTP client through command line options
-
-Note: This example assumes that network connectivity is already established.
-
-The NTP (Network Time Protocol) is a sophisticated protocol that provides
-high-precision time synchronization and is the standard for network time services.
-
-Configuration
-------------
-
-This example requires the following NuttX configuration options:
-
- CONFIG_NET: Enable networking support
- CONFIG_NET_UDP: Enable UDP support
- CONFIG_NETUTILS_NTPCLIENT: Enable NTP client support
- CONFIG_SYSTEM_NTPC: Enable this example
-
-Additional configuration options:
- CONFIG_NETUTILS_NTPCLIENT_SERVER: NTP server hostname (default: "pool.ntp.org")
-
-Usage
-----
-
-1. Configure your NuttX build with networking support
-2. Ensure network connectivity is established (e.g., via NSH network commands)
-3. Build and flash the image to your target board
-4. Run the commands:
-   - ``ntpcstart``, ``ntpcstop``, ``ntpcstatus``
-
-**Available Commands:**
-
- ``ntpcstart`` - Start NTP client in background
-
- ``ntpcstop`` - Stop the NTP client
-
- ``ntpcstatus`` - Display NTP client status information
-
-Expected Output
---------------
-
-**Start NTP client (ntpcstart):**
-::
-
-   Starting NTP client...
-   Using NTP servers: pool.ntp.org
-   NTP client started successfully (task ID: 123)
-   NTP client is now running in the background
-
-**Stop NTP client (ntpcstop):**
-::
-
-   Stopping NTP client...
-   Stopped the NTP daemon
-
-**Show NTP status (ntpcstatus):**
-::
-
-    The number of last samples: 3
-    [0] srv <ip> offset -0.033502142 delay 0.249973549
-    [1] srv <ip> offset -0.020698070 delay 0.029928000
-    [2] srv <ip> offset -0.015448935 delay 0.019815119
-
-**Verify using date command:**
-
-Given network connectivity is available, executing `date` should
-give the proper time and date.
-::
-
-    nsh> ntpcstart
-    Starting NTP client...
-    Using NTP servers: 0.pool.ntp.org;1.pool.ntp.org;2.pool.ntp.org
-    NTP client started successfully (task ID: 10)
-    NTP client is now running in the background
-    nsh> date
-    Fri, Sep 05 18:49:37 2025
-
-Notes
-----
-
- This example requires internet connectivity
- Network must be configured and connected before running this example
- NTP servers must be accessible (default: pool.ntp.org)
- UDP port 123 (NTP) must not be blocked by firewalls
- The example includes error handling for network failures
- NTP provides more accurate time synchronization than simple time protocols

 Semaphore does not support priority inheritance by default. If you need to
 use a semaphore as a mutex you need to change its default behavior.

-Each semaphore is assigned a default maximum value defined by SEM_VALUE_MAX.
-If ``CONFIG_CUSTOM_SEMAPHORE_MAXVALUE`` is enabled, applications may override this limit.
-In such cases, the function ``nxsem_setmaxvalue()`` can be used to specify a custom maximum value

Lars Kruse	b3dd8b2796	arch/arm/rp2040: merge conflicting definitions of `hw_*` functions The functions `hw_write_masked` and `hw_xor_bits` (as defined in pico-sdk) were defined in NuttX twice. Additionally these definitions were in conflict (one lacked the `volatile` modifier). Now these functions and their dependencies are defined in a new header file. Its name is based on the filename of the original definition in pico-sdk: src/rp2_common/hardware_base/include/hardware/address_mapped.h This change should fix the potential issue of GPIO operations failing due to compiler optimizations caused by the absence of `volatile`.

chao an	cf616fd619	arch/arm/armv8-m: stack pointer should be 8-byte aligned in signal context Since the alignment of the signal context is affected by XCPTCONTEXT_SIZE in different Kconfig, sometimes the stack pointer is not aligned to 8 bytes, this is not what the software and compiler expect, for example, if va_list() obtains wide data of type long long, the offset will be wrong, So in this commit, we set stack-aligned the base offset so that the correct offset will be set during context restoration. 1. test code: \| void signal_handler(int signo, siginfo_t info, void context) { \| long long ttt = 1024000; \| printf("%lld\n", ttt); \| } \| \| struct itimerspec its = { .it_value.tv_sec = 1, \| .it_value.tv_nsec = 0, \| .it_interval.tv_sec = 1, \| .it_interval.tv_nsec = 0 \| }; \| \| int main(int argc, FAR char *argv[]) \| { \| struct sigevent evp; \| timer_t timer_id; \| \| memset(&evp, 0, sizeof(evp)); \| evp.sigev_notify = SIGEV_SIGNAL \| SIGEV_THREAD_ID; \| evp.sigev_signo = SIGALRM; \| evp.sigev_notify_thread_id = gettid(); \| \| timer_create(CLOCK_REALTIME, &evp, &timer_id); \| \| \| struct sigaction sa; \| memset(&sa, 0, sizeof(sa)); \| sa.sa_sigaction = signal_handler; \| sa.sa_flags = SA_SIGINFO; \| sigemptyset(&sa.sa_mask); \| \| sigaction(SIGALRM, &sa, NULL); \| \| timer_settime(timer_id, 0, &its, NULL); \| \| while (1) \| sleep(1); \| \| return 0; \| } 2. before this change: \| NuttShell (NSH) NuttX-12.10.0 \| nsh> hello \| 4398046527890440 \| 4398046527890472 \| 4398046527890504 \| 4398046527890536 3. after this change: \| NuttShell (NSH) NuttX-12.10.0 \| nsh> hello \| 1024000 \| 1024000 \| 1024000 \| 1024000 Signed-off-by: chao an <anchao.archer@bytedance.com>	2025-09-27 21:41:20 +08:00

Jukka Laitinen	382ed6550f	imx9/imx9_usbdev.c: Fix interrupt handling in SMP mode The interrupt handler accesses the device as well as the driver's private data. Use critical_section for mutual exclusion with drivers/usbdev, which also protects the same data with critical_section.

MASZ	94ad260843	arch/arm/stm32h7: Fix and enhance WWDG (Window Watchdog) support This patch addresses several issues and adds enhancements to the WWDG (Window Watchdog) implementation for the STM32H7 platform. The changes include: - Extend the definitions of WWDG_CFR_PCLK1 macros to support dividers up to 128, and update the stm32_settimeout() function to consider this extended range. - Fix the "elapsed" calculations in the stm32_getstatus() function to ensure correct time remaining calculations. - Clear the EWIF (Early Wakeup Interrupt Flag) bit in the stm32_start() function, as this bit might be set by hardware before the watchdog is actually started. - Initialize the WWDG clock in the RCC_APB3ENR register and set the RCC_GCR_WW1RSC bit as per the STM32 reference manual to ensure proper behavior when enabling the WWDG1.
