The default sim:nsh config has no RTC, causing NSH_DISABLE_DATE to be
auto-enabled (default: DEFAULT_SMALL || !RTC). This means the date
command is not compiled in, and the system time defaults to a hardcoded
value instead of syncing with the host.
Enable CONFIG_RTC, CONFIG_RTC_DRIVER, and CONFIG_RTC_ARCH in the
sim:nsh defconfig so the date command is available and shows the
correct host time out of the box.

Add NULL check for g_uart_devs[i] before accessing ->priv in
arm_earlyserialinit() loop. When a USART is not enabled in defconfig,
g_uart_devs[i] is NULL, causing a HardFault crash during early boot.
The bug occurs because the original code only checked g_uart_devs[i]->priv
without first verifying g_uart_devs[i] is not NULL. On Cortex-M4, NULL
pointer dereference reads from Flash vector table (0x00000000 maps to
0x08000000), returning a function pointer that causes BusFault when
written to.
This fix matches the existing NULL check pattern used in arm_serialinit()
at line 2835 of the same file.
Tested on mplant-gd32f450 board with only USART5 enabled in defconfig.
Before fix: HardFault at boot (IPSR=3, PC=0x080003e0)
After fix: System boots normally to NSH Shell

This adds 3 configuration options for the lib_strftime, which can be
used to save flash memory when all the formatters are not needed by an
embedded application.
There is always a minimal set of formatters supported:
"%a, %b/%h, %d, %H, %m, %M, %S, %Y, %%". To add on top of that one can
specify:
- LIBC_STRFTIME_C_STANDARD_FORMATS : All ISO-C conversion specifiers
- LIBC_STRFTIME_POSIX_FORMATS : Additional posix formats
- LIBC_STRFTIME_NONSTANDARD_FORMATS : Additional GNU nonstandard formats
All of these are enabled by default unless building for CONFIG_DEFAULT_SMALL.
Disabling these options can save over 3KB of flash on an 32-bit
ARM system, when all the format specifiers are not needed.

The previous up_backtrace() relied entirely on host_backtrace() (a thin
wrapper around glibc's backtrace()), which can only unwind the host
thread that calls it. As a result, when assert / dump_tasks() walked the
task list and called sched_dumpstack() for every task, every task other
than the currently-running one returned a zero-length backtrace, and the
output was silently dropped. In practice this meant that on sim only
the crashing task ever produced a usable trace.
Fix this by walking the frame-pointer chain ourselves whenever the
target tcb is not the running task. Because sim's setjmp/longjmp is
provided by NuttX itself (libs/libc/machine/sim/arch_setjmp_*.S) and not
by host libc, the rbp/rsp/rip (or arm fp/sp/pc) saved in tcb->xcp.regs
are plain unmangled pointers, identical across Linux, macOS and Windows
hosts. The frame layout ([fp]=prev fp, [fp+1]=return address) is also
shared by every host ABI sim supports (x86, x86_64, ARM, ARM64).
The walker validates that fp lies inside the task's stack and is
properly aligned, and stops when fp[0] is NULL, so a corrupted stack
cannot make us read out of bounds. The running-task path is unchanged
and still uses host_backtrace() so DWARF unwinding through host
libraries continues to work.
Requires CONFIG_FRAME_POINTER=y so the compiler emits a usable fp link.

readdir() returned NULL at end-of-directory without ensuring errno was
clean. POSIX requires errno to be unchanged at EOF, but the underlying
read() path may leave a stale errno value. Callers that follow the
POSIX idiom (set errno to 0 before the call, test it after a NULL
return), such as readdir_r() and scandir(), then misread this as a
readdir() failure.
Save errno on entry and restore it on the end-of-directory return so
that EOF no longer reports a spurious error, while genuine errors
(read() returning a negative value) still propagate.

Replace the default nsh-based init flow on the lckfb-szpi-esp32s3 :adb
defconfig with system/nxinit so that services (sh console, adbd) are
spawned and reaped by init through /etc/init.d/init.rc.
- Enable CONFIG_SYSTEM_NXINIT and set INIT_ENTRYPOINT to init_main
(CONFIG_EXPERIMENTAL is required by SYSTEM_NXINIT).
- Add a common init.rc under boards/xtensa/esp32s3/common/src/etc/init.d
defining 'console' (sh) and 'adbd' services and starting both on init.
fastbootd is wired in for completeness when configured.
- Append the new init.rc to RCSRCS only when SYSTEM_NXINIT is enabled
so existing nsh-based configs remain unaffected.
Verified on lckfb-szpi-esp32s3 hardware: init_main spawns sh and adbd
(both with PPID=init), 'adb shell' reaches a working NuttShell.

uart_tcdrain() takes a caller-supplied timeout (e.g. 10s from the
TCDRN ioctl path), but the timeout was only applied to the final
TX-FIFO polling loop. The earlier xmit-buffer drain loop called
nxsem_wait(&dev->xmitsem) with no timeout, so any condition that
prevents the lower half from posting xmitsem (e.g. a stuck DMA
completion path, a wedged hardware-flow-control stall) would block
tcdrain() indefinitely, regardless of the timeout the caller asked
for. The pre-existing comment ("NOTE: There is no timeout on the
following loop. ... the caller should call tcflush() first") openly
acknowledged this hang.
Move the start timestamp before both phases and replace the bare
nxsem_wait() with nxsem_tickwait() using the remaining time, so the
total time spent in tcdrain() honors the caller's timeout regardless
of which phase stalls. When the remaining time is already exhausted,
short-circuit to -ETIMEDOUT without calling into the scheduler. The
existing exit path (drop critical section, skip the FIFO polling
loop, unlock the xmit mutex, leave the cancellation point) handles
the new -ETIMEDOUT propagation correctly without further changes.
Also fold the "Set up for the timeout" comment into the kludge
REVISIT comment, since the timestamp is no longer set up at that
point.

uart_tcdrain() registers a cancellation point on entry via
enter_cancellation_point() (when called with cancelable=true), and the
normal exit path calls leave_cancellation_point() before returning.
However the timeout path inside the FIFO drain loop returns -ETIMEDOUT
directly without going through the normal exit path, leaking one
cancellation point reference (tcb->cpcount is left incremented). Over
repeated timeouts this counter will desync and prevent
pthread_cancel() / pthread_setcancelstate() from behaving correctly
for the calling thread.
Fix by calling leave_cancellation_point() before the early return,
matching the existing exit path.

usrsock_ioctl_handler() copies req->arglen bytes from the request

Add three checks before the copy:
- len >= sizeof(*req): ensure the full request header is present.
- copylen <= len - sizeof(*req): payload must fit the received data.

nrf91_usrsock_ioctl_handler() copies req->arglen bytes from the
request payload into the fixed-size usrsock->out buffer without
validating that the payload actually fits either the received
request or the destination buffer. A crafted ioctl request with
an inflated arglen triggers:
1. OOB read — memcpy reads past the end of the received request.
2. OOB write — memcpy writes past the end of usrsock->out.
Add three checks before the copy:
- len >= sizeof(*req): ensure the full request header is present.
- copylen <= len - sizeof(*req): payload must fit the received data.
- copylen <= sizeof(usrsock->out) - sizeof(*ack): payload must fit
the destination buffer.
The recvfrom handler in the same file already performs the equivalent
buffer-size check (line 892). Fixes#18515.

The ROS 2 C client API generates symbols via rosidl token-pasting
macros. Each message type ends up with a name of the form
<pkg>__msg__<Type>, and the bare type token (Int32, Float64, ...)

Neither form can be renamed without breaking the public API.

geometry_msgs, sensor_msgs, nav_msgs, builtin_interfaces,
rcl_interfaces) and the rosidl scalar type names (Int8/16/32/64,
UInt8/16/32/64, Float32/64) to g_white_prefix so nxstyle does not
flag the resulting mixed-case identifiers in apps that consume
