The frame leaves the MAC later than the moment its hardware transmit
timestamp is latched, because of the clock domain crossing and the PHY.
This fixed delay is the egressLatency port parameter of IEEE 1588.
Add the configured latency to every hardware transmit timestamp
obtained through MSG_ERRQUEUE, the counterpart of the ingress
compensation.
- Add CONFIG_NETUTILS_PTPD_EGRESS_LATENCY_NS (default 0, which applies
no compensation).
- Add the -O option to override it at run time.
- Add egress_latency_ns to struct ptpd_config_s.

The MAC latches a hardware receive timestamp later than the frame
reaches the wire, because of the PHY and the clock domain crossing.
This fixed delay is the ingressLatency port parameter of IEEE 1588 and
shows up as a constant phase error between the local and the master
clock.
Subtract the configured latency from every hardware receive timestamp
in ptp_getrxtime(), the single place where they enter the daemon, so
Sync, Delay_Resp and the peer delay messages are all corrected.
- Add CONFIG_NETUTILS_PTPD_INGRESS_LATENCY_NS (default 0, which applies
no compensation).
- Add the -I option to override it at run time.

Implements the Peer-to-Peer (P2P) transparent clock delay measurement
mechanism (IEEE 1588-2008 §11.4 / IEEE 802.1AS / IEC/IEEE 61850-9-3)
in apps/netutils/ptpd:
- Add PTP_MSGTYPE_PDELAY_REQ, PTP_MSGTYPE_PDELAY_RESP, and
PTP_MSGTYPE_PDELAY_RESP_FOLLOW_UP definitions and structs in ptpv2.h.
- Define IEEE 1588-2008 Annex F peer delay multicast MAC address
01:80:c2:00:00:0e and Annex D peer delay IP address 224.0.0.107.
- Replace bool delay_e2e with enum ptp_delay_mechanism_e (PTP_DELAY_NONE,
PTP_DELAY_E2E, PTP_DELAY_P2P) in include/netutils/ptpd.h.
- Add -P CLI option in system/ptpd/ptpd_main.c with mutual exclusion
check against -E, and display last_transmitted_pdelayreq in status.
- Implement responder logic in ptp_process_pdelay_req() sending
Pdelay_Resp (t2) and Pdelay_Resp_Follow_Up (t3) regardless of master
or slave state.
- Implement requester logic in ptp_send_pdelay_req() gated on the
physical link without requiring prior BMCA master selection.
- Implement ptp_process_pdelay_resp() and
ptp_process_pdelay_resp_followup() using canonical mean path delay
formula ((t4 - t1) - (t3 - t2)) / 2.
- Refactor path delay bounds checking and moving average filter into
ptp_record_path_delay() shared across E2E and P2P mechanisms.
- Set PTP version 2.0 and controlField 0x05 in Pdelay_Req, Pdelay_Resp
and Pdelay_Resp_Follow_Up, and in the own-identity header, so that
peers such as linuxptp accept the messages.
- Clear pdelay_waiting_followup when a new Pdelay_Req is sent, so an
orphaned Pdelay_Resp_Follow_Up from an abandoned cycle is not paired
with stale timestamps.
- Warn at startup when P2P is selected without CONFIG_SCHED_TICKLESS,
since a tick-driven clock cannot resolve the peer delay.
- Skip IP multicast join/leave handling for AF_PACKET.

Port of the Zephyr RTOS zbus (many-to-many message bus with typed
channels and decoupled observers), built entirely on native NuttX
primitives and preserving the original declarative API
(ZBUS_CHAN_DEFINE, ZBUS_LISTENER_DEFINE, ZBUS_SUBSCRIBER_DEFINE, ...).
Features: listeners (synchronous callbacks), subscribers (queue of
channel references), message subscribers (ordered message copies),
async listeners (callback on a dedicated task), runtime observers,
per-observation notification masks, observer enable/disable, message
validators, channel user data, publish statistics, lookup by
name/numeric id and channel/observer iteration.
Mapping to NuttX primitives:
- Channel/observer registration: link-time iterable sections
(include/nuttx/iterable_sections.h); the observers of a channel are
named after their position in the definition, so the linker sorts the
notification order, and the declarative macros are built on
nuttx/macro.h (CONCATENATE, FOREACH_ARG and the FOREACH_IDX_ARG added
in a companion nuttx commit) rather than on a private macro engine.
Notification masks live in .bss with their initial value preserved in
ROM and applied on lazy init.
- Channel lock: sem_t (enable CONFIG_PRIORITY_INHERITANCE instead of
the Zephyr priority-boost/HLP); timeouts are computed with the
clock_timespec_* helpers from nuttx/clock.h.
- Subscriber queues: kernel message queues (file_mq_*) opened lazily
via pthread_once, usable from any task; mq payload copying replaces
the Zephyr net_buf machinery entirely.
- Async listeners: one task per listener (task_create, priority and
stack size configurable) blocking on the listener queue; a task
rather than a pthread so it outlives the first API caller.
- Timeouts: milliseconds with CLOCK_MONOTONIC deadlines
(ZBUS_NO_WAIT/ZBUS_FOREVER).
Includes a runnable example (examples/zbus, CONFIG_EXAMPLES_ZBUS) and a
cmocka test suite (testing/zbus, CONFIG_TESTING_ZBUS) covering the full
API: 17/17 tests passing on linum-stm32h753bi hardware, including
multi-channel index grouping, mask semantics, runtime observer error
paths, notification order (the observers of a channel run in the order
they are listed, and an observation bound with ZBUS_CHAN_ADD_OBS() runs
after all of them), queue overflow/timeout semantics, async listener
bursts,
bit-exact float/double payload delivery across every observer type
(sensor-style messages with a float-math validator) and an
interrupt-driven publisher (kernel timer interrupt -> signal -> sampling
thread -> zbus_chan_pub, the recommended pattern for interrupt sources).
Requirements: FLAT build; CONFIG_MQ_MAXMSGSIZE >= pointer size +
CONFIG_ZBUS_MSG_SUBSCRIBER_MAX_MSG_SIZE for message subscribers; board
linker script including <nuttx/linker/common-rom.ld> or the generic
CONFIG_ITERABLE_SECTIONS_LINKER_INSERT mode.
Not ported: multi-domain proxy agent (experimental upstream); publishing
from interrupt handlers (userspace library: hand the data to a thread).
Documentation lives in the nuttx repository
(Documentation/applications/system/zbus).

Migrate passwd encrypt/verify to PBKDF2 modular crypt format using
kernel cryptodev (CRYPTO_PBKDF2_HMAC_SHA256 via /dev/crypto). Add
passwd_pbkdf2 wrapper, base64url helpers, complexity validation, and
pbkdf2_test for RFC 6070 vector coverage. FSUTILS_PASSWD selects
CRYPTO, ALLOW_BSD_COMPONENTS, and CRYPTO_CRYPTODEV so existing sim
defconfigs keep building. Change NSH_LOGIN_USERNAME default to root and
remove fixed-login password defaults.
BREAKING CHANGE: TEA-encoded /etc/passwd entries no longer verify.
Regenerate each entry after upgrading. Pair with the nuttx host mkpasswd
changes in apache/nuttx#19209. Boards must enable the appropriate
software or hardware crypto backend for PBKDF2 at runtime. When
CONFIG_NSH_LOGIN_FIXED=y, set CONFIG_NSH_LOGIN_PASSWORD in the board
defconfig or menuconfig; there is no default password.

This commit fixes the audio_rtttl example (which was undocumented and
previously used kernel-level functions) such that now it uses the RTTTL
parsing library. Contributors can implement 'players' for different
types of audio sinks. Currently, PWM is supported.
BREAKING: The previous version of this example only supported a single
board (Spresense) and uses public interfaces from the kernel code. Now
it only uses user-space interfaces and supports any board implementing
those interfaces. Users who relied on the old behaviour should submit a
patch to add a new player to this application which uses the desired
audio sink for the Spresense through user-space interfaces.

Micro XRCE-DDS expects the application to supply open/close/write/read
callbacks for the wire transport. Add a single dispatcher that
registers the selected backend via rmw_uros_set_custom_transport(),
plus two backends:
transport/microros_transport_udp.c
BSD-socket UDP backend. Opens an AF_INET/SOCK_DGRAM socket,
resolves CONFIG_MICROROS_AGENT_IP/PORT, connect()s it, and uses
send/recv. The socket fd is stashed in uxrCustomTransport->args
so no module-level state is needed.
transport/microros_transport_serial.c
termios serial backend. Opens CONFIG_MICROROS_SERIAL_DEVICE with
O_RDWR|O_NOCTTY|O_CLOEXEC, switches to raw 8N1 at
CONFIG_MICROROS_SERIAL_BAUD, and uses poll/read/write. Fd is
again stashed in uxrCustomTransport->args.
Both backends are mutually exclusive at compile time via Kconfig;
the dispatcher selects which set of callbacks to register. Wired
into both the legacy Make build (CSRCS in system/microros/Makefile)
and the CMake build (separate microros_transport static library
with the transport directory only exposed to its INTERFACE).
