The initial modem import used a standalone infix-modem YANG module with
an integer-indexed list under /infix-modem:modems carrying a bearer
config mixed in with hardware config. Infix has adopted the ietf-hardware
model to allow for a clearer separation of concerns, this commit aims to
improve on that situation by refactoring the modem model to use the same
architectural pattern already used for WiFi radios, GPS receivers, and
USB ports:
Hardware:
/ietf-hardware:hardware/component[class=infix-hardware:modem]
/ietf-hardware:hardware/component[class=infix-hardware:sim]
Interface:
/ietf-interfaces:interfaces/interface[type=infix-if-type:modem]
Configuration split:
modem component — admin-state (enable/disable), radio access mode,
frequency bands, location services, probe-timeout
sim component — PIN, PUK, carrier profile
wwan interface — APN, IP type, roaming, route-preference, auth
This also enables the modem to appear in 'show hardware' alongside
other hardware components, and to be managed over NETCONF/RESTCONF
using the same ietf-hardware RPCs used for USB and WiFi.
YANG changes:
- infix-modem.yang removed (1089 lines, standalone module)
- infix-hardware.yang: new modem and sim containers, modem-state and
sim-state operational state, typedefs for bands/modes/location,
notification status-update; actions restart/reset/send-sms are
augmented directly on the component list entry (not inside container
modem) to work around sysrepo NP-container parent validation — when
checking a nested action's parent, sysrepo restricts its operational
data fetch to the container path, excluding the sibling 'class' leaf
needed to evaluate the container's 'when' condition, so the container
is never instantiated and the parent check fails
- infix-if-modem.yang: new submodule (same pattern as wifi/wireguard)
adds the wwan bearer container to ietf-interfaces
- infix-if-type.yang: new modem identity for wwan interface type
- confd version bumped to 1.9
confd:
- if-modem.c: new file replaces the stub modem_gen() in modem.c;
generates dagger init scripts with probe-timeout wait loop and
unconditional dummy wwan creation so downstream IP config succeeds
when a USB modem is slow to enumerate at boot
- hardware.c: start/stop/enable/disable modemd (and modem-manager)
in response to admin-state changes on the modem hardware component;
use finit_enable/disable consistently
- hardware_cand_infer_class(): auto-set class for modemN/simN names
- modem.c: stripped to RPC/notification forwarding only; the old
genconf() / enable() / disable() logic is gone — hardware.c owns
the lifecycle now
- interfaces.c: remove wwan from wait-interface timeout (the modem
interface appearance is managed by modemd, not confd's init scripts)
- migrate/1.9: script fully migrates /infix-modem:modems to the new
split model; each modem[N] becomes a modemN hardware component and
simN sim component; each bearer becomes a wwanN interface (bearers
numbered globally across modems); APN, IP type, roaming, preferred-
mode, bands, location, PIN/PUK/carrier are all carried over; plain-
text bearer credentials are moved to a named keystore symmetric-key
(base64-encoded) referenced from bearer/authentication/password;
apn-type, firewall-enabled, dns-enabled and default-route are
dropped (no equivalent in the new model)
modemd:
- load_config() replaces the infix-modem sysrepocfg call; reads from
ietf-hardware (modem/sim config), ietf-interfaces (bearer config),
and ietf-keystore (credentials) — three standard modules instead of
one proprietary one; modems absent from sysrepo config but present
in system.json are still started (physical detection wins)
- Default route written to /etc/net.d/<iface>.conf (picked up by
netd/staticd/zebra) instead of a direct 'ip route add'; routes are
now visible to FRR for redistribution and metric-based failover
- Addresses tagged with proto wwan (rt_addrprotos entry 7) for
precise flush on disconnect without touching other address sources
- _derive_gateway() handles point-to-point bearers where modem
reports gateway as "--"; derives peer from link-scope subnet route
- SimThread exits cleanly on platforms without /dev/simctrl
- sim-setup, modem-info, modem-udev, modem-rpc, modem-sms all ported
to the ietf-hardware/ietf-interfaces namespace
statd:
- infix_modem.py now emits modem-state and sim-state into ietf-hardware
component entries (modem0, sim0, ...) instead of a separate tree;
sim-state reports physical slot, lock state, and SIM operator name
- ietf_hardware.py: hardware component names deduplicated by rename
(cpu → cpu, cpu1, ...) to prevent LY_EVALID when hwmon and thermal
sysfs both normalise to the same sensor name
- show hardware: Cellular Modems and SIM Cards tables added; sensor
table width now adapts to the widest section in the output
- 00-probe: USB modem detection writes to system.json["modem"], same
source as wifi-radios, feeding gen-hardware which emits the
ietf-hardware component entries at factory config generation time
CLI:
- 'show modem [ref]': without ref shows Cellular Modems and SIM Cards
tables (same data subset as 'show hardware'); with ref shows a full
per-modem dump (hardware info, status, cellular, SIM, bearers, GPS)
- 'modem restart <ref>': disconnect and reconnect all bearers without
a full hardware reset
- 'modem reset <ref>': factory-reset the modem firmware
- 'modem sms <ref> <number> <message>': send an SMS via the modem
(uses the signalling plane; no active data bearer required)
- MODEMS PTYPE provides tab-completion reading modem names from
/run/system.json
doc:
- Add initial User Guide for modems
- Update ChangeLog with modem news
- Use absolute URLs in ChangeLog. Relative links only work for in-tree

In the last major refactor of confd to a stand-alone daemon, new command
line options were added, one of which -v <LEVEL>. Unfortunately opening
up for a few corner cases where the debug flag or the log_level was not
set properly.
This fixes that and also adds a CONFD_ARGS for /etc/default/confd, which
is customary for all daemons.

Use SR_SUBSCR_NO_THREAD for all subscriptions and integrate sysrepo
event pipes into a libev event loop. This eliminates approximately 30
per-subscription threads, reducing overhead on embedded ARM hardware.
A temporary poll-based "event pump" thread handles callback dispatch
during bootstrap (where sr_replace_config blocks waiting for callbacks),
then exits. After bootstrap, the single-threaded libev loop takes over
for steady-state event processing.
Note, the confd-test-mode plugin still requires use of threads so we do
not create deadlocks when calling sr_replace_config().

Allow confd to start even earlier at boot and call 'gen-config' as a
background task, pending on it to complete before we load the sysrepo
factory datastore.
Also, add Finit style progress to console so users can see the phases
of the bootstrap process.

Infix technically does not need to start dbus and dnsmasq before confd
has loaded the system startup-config. So we move it in time to save

On single-core Cortex-A7, the YANG bootstrap and config loading is the
dominant boot bottleneck. The current sequence spawns three serial
phases (bootstrap, sysrepo-plugind, load), each performing independent
sr_connect()/sr_disconnect() cycles, and every sysrepoctl/sysrepocfg
invocation is a fork+exec that rebuilds SHM from scratch.
Replace all three with a single confd binary that does one sr_connect()
and performs all datastore operations in-process:
- Wipe stale /dev/shm/sr_* for a clean slate
- sr_install_factory_config() from the generated JSON
- Smart migration: compare config version via libjansson, only
fork+exec the migrate script when versions actually differ
- Load startup-config (or test-config) via lyd_parse_data() +
sr_replace_config(), mirroring what sysrepocfg -I does internally
- On failure: revert to factory-default, load failure-config, set
login banners (Fail Secure mode)
- On first boot: copy factory-default to running, export to file
- dlopen plugins and enter event loop
The bootstrap shell script is split: config generation (gen-hostname,
gen-interfaces, etc.) stays in the new gen-config script, while all
sysrepo operations move into the C daemon. The finit boot sequence
collapses from 5 stanzas to 2 (gen-config -> confd).

Previously rousette did not install the yang models so we kept a copy
of them in confd. Now it is implemented in rousette, let them install
their models.
Please note, this change drops not only the global enabled flag, but also the
per-interface enabled flag, converting it to a presence container. The name
of the container is also shortened from dhcp-client -> dhcp. A pattern that
expected to be reused also for the DHCPv6 client.

Support implemented:
* WPA2/3 support
* scanning (in background, results in operational)
* Unencrypted networks
No certificate support, only PSK
*only* client so far, no AP
Non-privileged users in the sys-cli group can now access sysrepo data.
The data is now solely protected by the NCAM rules and not Unix file
permissions. Any stray user that's not part of the (default) sys-cli
group still can't access syrepo, like users added from the shell.

Sysrepo, netopeer etc are still responsible to install the modules in
target directory, this will make that we will discover quickly if something
is updated.
Also this enables rm -rf output/target/etc/sysrepo/data/* && make confd-rebuild
This will reinstall all modules again.
There is no such loglevel 'critical', only 'crit' is defined.
For some reason this issue has not been spotted until the upgrade to
Buildroot 2025.02, which includes sysklogd v2.7.0, and Finit v4.11.

Turns out the root cause for the odd log message in #896 was that the
system did not properly call `resolvconf -u` when starting in failure
mode.
This patch simplifies the code by moving all `resolvconf -u` calls to
the same Finit task. Ensuring it is first launched when confd has
successfully consumed any configuration at boot, and then every time
a static DNS server is added. (The udhcpc client script already call
`resolvconf -u` when dynamic DNS servers are learned.)

For consistency with the new dhcp-server model, which has an option
value 'name', options are now referred to as id's or identifiers.
This means bumping the confd syntax version 1.3 -> 1.4 and adding a

Some services launched at bootstrap must be possible to override per

led condtion, preventing Finit from lauching iitod. Also, rename the
ixinit-done condition to match the nomenclature used already.

Now that we have a unified timeout value that all front-ends should
honor, make sure to do so when loading startup-config and
failure-config during boot.
This fixes an issue where the system would fallback to failure-config
even though a legitimate startup-config was available, but took more
than 10s to apply.
While sysrepo's architecture places the responsibility of choosing a
timeout on each front-end, we want to control it centrally since the
majority of the time is spend actually applying the config to the
system - which is front-end agnostic.
Therefore, create a single definition of the timeout, which can be
included by all front-ends.
This commit introduces a new SECURITY() log macro that logs to facility
'audit' (sometimes called 'security') with severity set to 'alert'. It
is then used to instrument the single most important things to log; all
changes to users and their privileges.
We also add logging to sysrepo, which knows the username for changes to
running-config, copies to startup-config, and RPCs.

Currently, it's not possible to run infix tests from an external
project (based on infix) due to an incompatibility between the
configuration used in the tests (the default configuration
within the image generated by the external project) and the infix
base configuration expected by the test cases. Therefore, a simple
configuration specifically for testing purposes needs to be generated
within an image. This test-config should always be generated
but only loaded when the device is in test mode.

First, actually remove setup.sh. No reason to have the old version
lingering in the repo confusing devs. Also simplify script heading
dropping previous netopeer2 text and distilling the comment before

Silence the install/update, dropping -v -- no need to be overly verbose

Crucially -- fix a bug in UPDATE_MODULE(), missing closing '
Simplify naming and location of .inc files. No need for the long
filenames, or the new directory, the directory name gives plenty of
context.
Add reminder of duplicate infix-interfaces.yang in .inc files -- this
duplication is unfortunate and we should try to fix this better. We
will forget to update one or the other any day ...

- Fix indentations:
- Corrected indentations in confd.mk to adhere to Buildroot coding
standards
- Relocate YANG Modules List Files:
- Moved the YANG modules list files (.inc) from package/confd to
src/confd
- Add Missing YANG Module:
- Included infix-interfaces@2024-01-15.yang in
yang_modules_confd.inc
- This module was missing in the non-containerized build and is now
correctly added
- Moved setup.sh and yang_modules files from infix/src/confd/scripts/ to infix/utils/ to streamline the repository structure
- Updated confd.mk to correctly reference the new location of the setup script
- Introduced yang_modules_<type>.inc file to list all YANG modules for improved clarity and maintainability
- Modified the new setup script to dynamically source module lists from yang_modules_<type>.inc
This makes it easier to add more scripts without having to update the
finit config file, and it clarifies which of the scripts in
/libexec/infix only execute at boot.
This to hopefully speed up boot, do as little as possible
during boot.
* New modules needs to be added to src/confd/scripts/setup.sh
* Permission needs to be changed post-build for YANG files,
see CONFD_PERMISSIONS in confd.mk
Instead of having a chown process started by Finit in runlevel S, we can
just chown in the confd load script instead.
