Introduce networking capabilities to the Creator CI20 board by leveraging
the pre-existing dm9000 ethernet driver.
To achieve this, the following changes were made:
- Integrated the jz4780 GPIO module to properly configure and enable the
interrupt pin required by the ethernet controller.
- Added `dm90x0.h` to export the dm9000 initialization function, allowing
the board-specific setup code to initialize the network interface.

blksize_t is currently defined as int16_t, which overflows when a
filesystem reports a block size larger than 32767 bytes. This causes
st_blksize to become zero, leading to an integer divide-by-zero when
st_blocks is calculated in stat().
Widen blksize_t to int32_t to support larger filesystem block sizes.
Update nuttx_blksize_t in include/nuttx/fs/hostfs.h to keep it
consistent with include/sys/types.h.
struct geometry.geo_sectorsize (include/nuttx/fs/ioctl.h) is also

The existing CRYPTO_AES_CTR is the RFC 3686 profile: the last 4 bytes of
the key are a nonce, the IV is 8 bytes and only the low 32 bits of the
counter block are incremented. SSH aes128/192/256-ctr (RFC 4344) instead
uses the key as-is (no embedded nonce) and treats the whole 16-byte IV as
the initial counter block, incremented as a 128-bit big-endian integer,
with the first keystream block being E(IV).
Add CRYPTO_AES_CTR_SSH as a new enc_xform mirroring the CRYPTO_CHACHA20_DJB
addition. It reuses struct aes_ctr_ctx and the AES block; only setkey (full
key, no nonce), reinit (full 16-byte counter) and crypt (encrypt-then-
increment over all 16 bytes) differ from the RFC 3686 variant.
Keystream validated against `openssl enc -aes-128-ctr`, including a counter
that carries across byte boundaries and a non-block-aligned tail.

nsh_fileapp() could not apply an application's Kconfig-configured
priority/stacksize via posix_spawn() under CONFIG_BUILD_KERNEL, because
the registry table (struct builtin_s / g_builtins[]) was gated on
CONFIG_BUILTIN, which depends on !BUILD_KERNEL. Those settings were
silently ignored in KERNEL builds.
CONFIG_BUILTIN conflates the table with main_t-based dispatch, which is
meaningless under CONFIG_BUILD_KERNEL. Add a hidden derived symbol,
APP_REGISTRY, that tracks table availability independently of dispatch:
config APP_REGISTRY
bool
default y if BUILTIN || BUILD_KERNEL
Switch the guards on the table itself (Make.defs, builtin.h) from
CONFIG_BUILTIN to CONFIG_APP_REGISTRY. Call sites that dereference
builtin->main stay gated on CONFIG_BUILTIN and remain unreachable
under CONFIG_BUILD_KERNEL.

CRYPTO_CHACHA20 implements the RFC 8439/IETF parameterization (32-bit
counter + 96-bit nonce). SSH's chacha20-poly1305@openssh.com uses the
original DJB construction instead: a 64-bit block counter in state
words 12..13 and a 64-bit nonce in words 14..15 (libtomcrypt's
chacha_ivctr64). The two layouts produce different keystreams for the
same key, so an SSH server cannot interoperate with OpenSSH clients
through the IETF variant.
Signed-off-by: Felipe Moura <moura.fmo@gmail.com>
Expose the ChaCha20 stream cipher and the ChaCha20-Poly1305 AEAD through
the OCF crypto framework (/dev/crypto) so applications such as an SSH
server (chacha20-poly1305) can use them directly, and fix the underlying
ChaCha nonce/counter layout so both match RFC 8439.
RFC 8439 nonce layout fix
-------------------------
chacha_ivsetup() previously used the original DJB layout: a 64-bit block
counter (input[12..13]) followed by a 64-bit nonce (input[14..15]). RFC
8439 defines a 32-bit block counter (input[12]) and a 96-bit / 12-byte
nonce (input[13..15]). With the old layout the existing ChaCha20-Poly1305
AEAD could not reproduce the RFC 8439 test vectors (the last 4 bytes of a
12-byte nonce were consumed as the high half of the counter). This
commit switches chacha_ivsetup() to the RFC 8439 layout and updates the
ChaCha20-Poly1305 one-shot helpers to pass a 12-byte nonce accordingly.
Standalone ChaCha20 on the unified enc path
-------------------------------------------
Instead of introducing a separate multi-buffer stream path (parallel
encrypt_multi/decrypt_multi callbacks), extend the existing enc_xform
encrypt/decrypt callback signature with a length argument:
void (*encrypt)(caddr_t, FAR uint8_t *, size_t len);
void (*decrypt)(caddr_t, FAR uint8_t *, size_t len);
With that single change every cipher, block or stream, flows through the
same swcr_encdec path. swcr_encdec already handles a short final block
via buflen = MIN(i, blocksize), so arbitrary-length data works without a
second code path. This is exactly how the existing stream ciphers
(AES-CTR/OFB/CFB) already behave: the cipher keeps its own counter in the
context and swcr_encdec feeds it whole blocks (only the last one may be
shorter). chacha20_crypt likewise relies on the underlying chacha state
block counter (input[12]) to continue the keystream across calls, so no
per-call keystream caching is needed.
* chacha_private.h: chacha_ivsetup uses a 4-byte counter and a 12-byte
nonce (RFC 8439).
* chachapoly.c / chachapoly.h: split reinit into chacha20_reinit (raw,
counter 0) and chachapoly_reinit (AEAD, counter 1); chacha20_crypt
takes a length and encrypts it in one pass, mirroring aes_ctr_crypt;
12-byte nonce for the one-shot AEAD helpers.
* xform.h / xform.c: add size_t len to encrypt/decrypt; add
enc_xform_chacha20 (blocksize 64, 12-byte IV).
* cryptodev.c / cryptosoft.c: register CRYPTO_CHACHA20 as a txform
cipher, route new sessions to enc_xform_chacha20, feed the AEAD AAD
through crp_aad/crp_aadlen, and handle the short final block in
swcr_encdec.
* cryptodev.h: add CRYPTO_CHACHA20; bump EALG_MAX_BLOCK_LEN to 64.
This keeps all ciphers on one uniform path instead of maintaining two,
and any future stream cipher drops in with just an xform table entry.
Impact: extends an internal kernel callback signature (enc_xform
encrypt/decrypt). All in-tree implementations are updated in the same
commit and the user-facing /dev/crypto ABI is unchanged, so this is
self-contained and not a breaking change for existing configurations.
Testing:
Build host: Ubuntu Linux x86_64, GCC (host sim toolchain)
Target: sim:crypto (CONFIG_ARCH=sim)
Ran the crypto test apps. ChaCha20 uses RFC 8439 2.4.2 vectors
(including a 375-byte multi-block vector exercising cross-block counter
continuity); ChaCha20-Poly1305 uses the RFC 8439 2.8.2 AEAD vector.
A full regression of the other ciphers was run to confirm the extended
encrypt/decrypt signature does not change their behaviour:
nsh> chacha20
chacha20: 2/2 vectors passed
nsh> chachapoly
OK test vector 0
chachapoly: 1/1 vectors passed

NuttX has no real session/process-group abstraction, so the TTY layer
collapses the foreground process group onto the single dev->pid field
(pgrp == pid, one member per group). Extend the controlling-terminal
support so portable software (e.g. dropbear, socat) that relies on
job-control primitives works without losing the existing NuttX-specific
behaviour.
Driver (serial.c, pty.c):
- TIOCSCTTY now accepts a flag: arg > 0 keeps the historical "target
PID in arg" semantics (NSH registers the foreground command it just
spawned), while arg == 0 selects the calling task via
nxsched_getpid(), matching the POSIX flag convention used by
dropbear/socat/apue. This preserves all existing callers and makes
the previously-dead arg==0 path deliver SIGINT correctly.
- Add TIOCGPGRP/TIOCGSID (return dev->pid) and TIOCSPGRP (set it).
- pty.c gains the same handlers against pd_pid and includes
nuttx/sched.h for nxsched_getpid().
ioctl numbers (tioctl.h): TIOCGPGRP/TIOCSPGRP/TIOCGSID at 0x37-0x39.
libc wrappers:
- termios: tcgetpgrp(), tcsetpgrp(), tcgetsid() over the new ioctls.
- unistd: setsid()/getsid()/setpgid() stubs consistent with the
existing getpgrp()/getpgid() single-session model (sid == pgid ==
pid; setpgid only succeeds for pgid == pid).
Declare the new prototypes in unistd.h (tcgetsid was already in
termios.h) and register all sources in the Make.defs/CMakeLists.
Group-broadcast signalling (kill(-pgrp)) remains unsupported, so
tty signals still target the single dev->pid; a real session/process
group model is left as a follow-up.

POSIX leaves the signedness of time_t and clock_t unspecified, but
mainstream implementations (Linux glibc/musl, the BSDs, macOS, RTEMS,
Zephyr's POSIX layer, Windows _time64) expose time_t as signed 64-bit.
NuttX has historically used uint64_t only because it was tied to the
CONFIG_SYSTEM_TIME64 knob; with that gone, switch:
time_t : uint64_t -> int64_t
clock_t : uint64_t -> int64_t
CLOCK_MAX: UINT64_MAX -> INT64_MAX

- include/nuttx/{mqueue.h,wdog.h,wqueue.h,timers/clkcnt.h}
Because clock_t is now signed 64-bit, the NuttX-internal sclock_t
alias becomes redundant: every sclock_t/SCLOCK_MAX use is folded
back to clock_t/CLOCK_MAX (notably in sched/wdog, sched/mqueue,
sched/sched, sched/clock, sched/timer, libs/libc/time, fs/vfs and
the drivers/arch consumers below).
Tick/period constants (NSEC_PER_SEC, USEC_PER_SEC, MSEC_PER_SEC,
SEC_PER_MIN, ...) in include/nuttx/clock.h are retyped from "long"
literals to INT64_C(...) so that 64-bit arithmetic no longer
depends on the host's long width.
Strip now-redundant (time_t)/(clock_t)/(unsigned long) casts and
unsigned-only branches across the tree:

The 32-bit system clock has a limited range (~497 days) and the
configuration knob is no longer worth the complexity given that
practically every modern target already enables it. Make 64-bit
time_t/clock_t/sclock_t/nuttx_time_t the only supported flavor.
Specifically:
- Drop the SYSTEM_TIME64 Kconfig option and its dependent
PERF_OVERFLOW_CORRECTION/HRTIMER guards in sched/Kconfig.
- Remove every #ifdef CONFIG_SYSTEM_TIME64 branch in headers
(include/{sys/types.h,limits.h,inttypes.h,nuttx/clock.h,
nuttx/fs/hostfs.h}) and core code paths
(sched/clock/clock.h, drivers/power/pm/pm_procfs.c,
drivers/rpmsg/rpmsg_ping.c, fs/procfs/fs_procfsuptime.c,
libs/libc/wqueue/work_usrthread.c,
arch/avr/src/avrdx/avrdx_timerisr_tickless_alarm.c).
- Strip CONFIG_SYSTEM_TIME64=y from every board defconfig.
- Update Documentation/guides/rust.rst accordingly.

Every compiler supported by NuttX provides the "long long" types,
so the CONFIG_HAVE_LONG_LONG indirection is no longer useful.
Remove the option from include/nuttx/compiler.h and treat
"long long" as unconditionally available across the OS.
In addition to deleting the guard itself, this commit unconditionally
enables the long-long flavored helpers that used to be gated behind
it:
- libs/libc/fixedmath: drop the soft-emulated b32/ub32 routines
in lib_fixedmath.c (-261 lines) and trim the matching
prototypes, Make.defs and CMakeLists.txt entries; keep only
the long-long backed implementations.
- include/sys/endian.h, include/strings.h, libs/libc/string
/lib_ffsll.c, lib_flsll.c: always expose the 64-bit byte-swap
and ffsll/flsll variants.
- libs/libm/libm/lib_llround{,f,l}.c: drop the empty stubs.
- libs/libc/stdlib (atoll, llabs, lldiv, strtoll/ull, rand48,
strtold), libs/libc/stream (libvsprintf, libvscanf,
libbsprintf, ultoa_invert), libs/libc/misc (crc64, crc64emac),
libs/libc/inttypes/strtoimax, libs/libc/lzf, libs/libc/libc.csv,
libs/libc/string (memset, vikmemcpy): remove the
#ifdef CONFIG_HAVE_LONG_LONG branches.
- include/{stddef.h,stdlib.h,fixedmath.h,sys/epoll.h,cxx/cstdlib,
nuttx/audio/audio.h,nuttx/crc64.h,nuttx/lib/math.h,
nuttx/lib/math32.h,nuttx/lib/stdbit.h}: same guard cleanup.
- drivers/note/note_driver.c, fs/spiffs/src/spiffs.h,
sched/irq/irq_procfs.c: drop their local guards as well.
- Documentation/applications/netutils/ntpclient/index.rst:
refresh the documentation snippet.

BREAKING CHANGE: remove PWM_MULTICHAN option
PWM_MULTICHAN option is redundant, we can just set CONFIG_PWM_NCHANNELS > 1.
At default CONFIG_PWM_NCHANNELS is set to 1, so the default behavior is preserved.
Access to single channel API is now `info->channels[0].XXX` instead of `info->XXX`
This is the first step to simplify PWM implementation and make it more portable.
