nuttx_add_application() encoded SCHED_PRIORITY_DEFAULT as a zero-valued nx_priority linker symbol. A zero priority is invalid for a runnable ELF application task.
Do not emit nx_priority for the symbolic default. When the symbol is absent, the ELF loader retains its scheduler default. Continue emitting nx_priority for explicit numeric priorities.
Companion to apache/nuttx-apps#3667.

Program names containing '-' (for example, renaming hello to
hello-world via PROGNAME) previously generated an invalid identifier
<NAME>_main when constructing the main= compiler definition and the
APP_MAIN target property used during builtin list generation. This
caused the CMake build to fail because '-' is not a valid character in
a C identifier.
This mirrors the Make-based fix (Application.mk's PROGSYM) for the
traditional build.
Introduce NAME_SYM, a sanitized copy of NAME with '-' replaced by '_',
and use it only where an internal C identifier is required: the
main= COMPILE_DEFINITIONS property and the APP_MAIN target property.
Leave NAME unchanged everywhere else, including CMake target/output
names and the APP_NAME property, where hyphens are valid.
The standalone/loadable executable path (MODULE/DYNLIB/kernel build)
does not rename main() and therefore requires no sanitization because
each executable is linked independently rather than merged into a
shared builtin image.
Testing (WSL2 Ubuntu, x86_64):
- BOARD_CONFIG=sim/nsh, CONFIG_EXAMPLES_HELLO_PROGNAME="hello-world":
clean CMake configure/build; 'hello-world' runs and prints
'Hello, World!!'
- Reverted to CONFIG_EXAMPLES_HELLO_PROGNAME="hello": reconfigured
and rebuilt; 'hello' runs and prints 'Hello, World!!' (no
regression)

Remove implicit default credentials and add build-time validation.
Add check_passwd_keys.sh and gen_passwd_keys.sh; run key setup via
passwd_keys.mk before config.h is generated. Mirror the same logic in
cmake/nuttx_add_romfs.cmake for CMake builds.
BREAKING CHANGE: Builds with CONFIG_BOARD_ETC_ROMFS_PASSWD_ENABLE=y now
require an explicit admin password and non-default TEA keys. The
Kconfig default password "Administrator" and default TEA keys are no
longer accepted. Fix: run make menuconfig, set Admin password under
Board Selection -> Auto-generate /etc/passwd, enable random TEA keys or
set CONFIG_FSUTILS_PASSWD_KEY1..4 manually, and use NSH login with
Encrypted password file verification.

1. The .kasan.unused and .kasan.global sections contain compiler-generated
data with the WRITE flag (.data..LASAN*), but the linker script placed
them before .text without specifying a memory region. The linker could
not put writable sections into the read-only ROM (rx) region, so it
silently placed them at 0x40000000 in RAM, creating an extra LOAD
segment that conflicts with QEMU virt's RAM layout and causes boot
failure.
2. The .kasan.global should be placed before .data because .data
patten (*(.data*)) includes .kasan.global pattern (*(.data..LASAN0)),
and it cause kasan_global.py cannot find .kasan.global section to
generate the g_global_region array.
3. Move .kasan.shadows from before .text to after .rodata. Placing it
before .text causes .text to shift when .kasan.shadows transitions
from empty (pass 1) to populated (pass 2+), preventing the multi-pass
link addresses from converging. After .rodata it does not affect any
upstream section addresses.
4. Add CMake post-build step to strip .kasan.unused and .kasan.global
sections from the final binary, matching the Makefile build behavior.

Add a custom aarch64 Mach-O Rust target for macOS sim builds and use it
instead of an Apple Darwin Rust target. This keeps Rust cfg values aligned
with NuttX while producing Mach-O objects required by the simulator link.
Also align sim host handling for aarch64 Linux by detecting `aarch64` as
`HOST_ARM64` and avoiding x86-specific `-mcmodel` and `-no-pie` options
on ARM64 hosts.

Introduce mkpasswd, a pure-C host tool for generating encrypted password
files at build time using TEA encryption. This enables secure,
credential-free firmware images while allowing build-time password
configuration.
Changes:
* Add mkpasswd.c host tool for TEA-based password hashing and encryption
* Integrate mkpasswd into Make build system (tools/Makefile.host)
* Add CMake support for mkpasswd compilation and ROMFS passwd generation
* Add CONFIG_BOARD_ETC_ROMFS_PASSWD_* configuration options to Kconfig
* Implement credential exclusion from defconfig to prevent password leaking
* Update savedefconfig.cmake to strip sensitive credentials
* Fix mkdir() portability for Windows Native builds (CONFIG_WINDOWS_NATIVE)
* Change default username from "admin" to "root" (POSIX convention)
* Improve build-failure error message with full menuconfig navigation path
BREAKING CHANGE: Boards enabling CONFIG_BOARD_ETC_ROMFS_PASSWD_ENABLE
must set CONFIG_BOARD_ETC_ROMFS_PASSWD_PASSWORD to a non-empty string
of at least 8 characters. The build now fails with an explicit error if
this config is left empty. To fix: run 'make menuconfig' and navigate to:
Board Selection --->
Auto-generate /etc/passwd at build time --->
Admin password
