# Changelog
All notable changes to `thermal-guard` and `luci-app-thermal-guard`.
Versions follow `Major.Minor.Patch`; both packages are released
together and carry the same number.
## 2.0.0
### Breaking changes
- **Breaking: `trip_dt` is no longer a UCI option.** The daemon used to write
it into `/etc/config/thermal-guard` from the running process, next to the
operator's own edits. The device tree trips that `trip_active` was made for
now live in `/etc/thermal-guard/trip_base`, written on the first cycle with
`trip_active` set and kept across a sysupgrade. Without `trip_active` the file
is neither read nor written. The package moves an existing `trip_dt` there
once (`/etc/uci-defaults/90-thermal-guard-trip-base`) and removes the option;
a leftover `trip_dt` is ignored. The daemon no longer writes UCI.
- **Breaking: `fan_cooling_device` and `fan_thermal_zone` are gone.** Both
named a numbered path (`cooling_device0`, `thermal_zone0`), and those numbers
can change between boots, which is what the detection by type avoids. The
fan is found by `fan_cooling_device_type`, its zone by the link to it. A
value left in an old configuration is ignored like any unknown option.
### Notes for operators
- **Syslog filters may need adjusting.** Every line now carries a
`daemon.*` priority instead of `user.notice`: `crit`, `warning`, `notice`,
`info` as listed under Changed. A `logread` filter or remote syslog rule
written for `user.notice` no longer matches.
- **New dependency `jsonfilter`.** `base-files` already ships it on every
OpenWrt and ImmortalWrt image, so nothing new gets installed there.
- **Update both packages together.** The config page's answer to a changed
firmware runs `thermal-guard trips-keep`, which needs the daemon and the
rpcd ACL of this release; the ACL grants exactly that command line.
### Added
- **`thermal-guard trips-keep`** records the device tree trips of the running
boot as the ones `trip_active` was made for. The config page runs it for both
answers to the new firmware notice; the ACL grants exactly this command line.
### Changed
- **README: a section on known limitations**: ModemManager and `at_lock`,
notifications without `curl`, boards that report no temperature, and
`wifi_off` on radios netifd does not manage.
- **Without `curl`, a notification address with a query string or user info
is refused.** `uclient-fetch` and `wget` take the address on the command
line, where every local process can read it in `/proc`, so a token in
`?token=...` or `user:pass@host` would leak. The check runs when the
configuration loads and clears `notify_url`, so nothing piles up in the
outbox; the notify hook still works. An address without `http://` or
`https://`, or with characters `curl` would misread, and a malformed
`notify_header` are now rejected at load for the same reason. Each reason is
logged once, the address itself never. A secret in the path of the address
(Slack, Discord, a private ntfy topic) cannot be detected and stays visible
without `curl`; the README says so.
- **A notification post without `curl` has a time limit.** `uclient-fetch` and
`wget` run under `timeout` (`HTTP_TIMEOUT`, 20 s by default) with `-T 15` for
the network wait, so a hung DNS lookup or server costs one message instead of
blocking the loop. The `curl` path keeps its `-m 15`.
- **`wifi_off` is read back.** It was the only built in stage action that
trusted the exit code of `wifi down`. Now the command is sent up to five times
with 5 s in between (`WIFI_SETTLE`), and the action succeeds only when
`ubus call network.wireless status` reports no radio up; the way back after a
reset waits until every radio that is not disabled is up. Checked against the
real netifd answers of a Banana Pi R3 Mini (`mt_wifi`) and a GL-X3000, kept as
test fixtures.
- **Time limits for `wifi`, `ifdown`, `ifup` and every hook.** The commands get
15 s (`CMD_TIMEOUT`), the `notify`, `stage1` and `stage2` hooks 15 s
(`HOOK_TIMEOUT`), the `modem-temp` hook 5 s. A hook that ignores TERM is killed
5 s later. Before, a hung command or hook held the whole loop.
- **The config page checks what the daemon will use.** The order of the
thresholds is checked against the values in the form, not the saved ones,
and an empty field counts as the daemon's default; before, `cpu_warn` 85 with
`cpu_crit` left empty passed and made the daemon fall back to all defaults.
A threshold like `85abc` is refused. `interval` takes whole numbers of 5 and
more only. `fan_governor` is a list of the four governors the daemon accepts.
- **`fan_governor` only takes a kernel governor that regulates:**
`step_wise`, `fair_share`, `bang_bang` or `power_allocator`. Before, any
string went to the zone's `policy` on reset, `user_space` included, which
leaves nothing regulating the fan. Anything else now means `step_wise` and is
logged once.
- **Syslog lines carry a priority** instead of the default `user.notice`:
`daemon.crit` for stages, restored stages, a stage that cannot be persisted
and failed stage actions (also a modem or interface that does not come back
after a reset), `daemon.warning` for rejected options, missing tools, a
sensor that does not read and trips that could not be written,
`daemon.notice` for cooled down, reset, `trips-keep` and new firmware trips
that need a decision, `daemon.info` for the rest. The `blind:` message for a
CPU sensor that stops reading ran through the stage 0 path and would have
been `crit`; it is a `warning` and is still notified. The event log format
is unchanged.
- **netifd's answers are read with `jsonfilter`** instead of `sed` and `awk` on
the text of `ubus` output, which depended on its indentation. Every `ubus
call` has a time limit of 5 s (`UBUS_TIMEOUT`): netifd answers late while
`wifi down` runs, and the readback must not hang on exactly what it checks.
A radio counts as enabled unless netifd reports it `disabled`; the Wi-Fi log
line counts only those. `jsonfilter` is now in `DEPENDS`; `base-files`
already pulls it into every image.
- **The configuration is read with one `config_load` per cycle** instead of
one `uci -q get` per option, about 40 processes every 20 s. The checks on
the values are unchanged.
- **The detected fan pwm output is logged once as `fan pwm output detected at
'...'`.** Before it read `fan pwm path '' unusable`, although nothing was
configured. A configured `pwm_path` that stopped working is still reported
as unusable, once per replacement.
### Fixed
- **Four help texts on the config page say what the service does** (English
and German): `fan_governor` applies only when no earlier control mode was
recorded; `hold_minutes` starts stage 2 of 3 when the temperature has not
dropped and stage 3 of 3 only while it still rises; the `zone_path` reason
names the fan's zone, which is no longer configured; `uplink_interface`
decides whether a message goes out or is queued, not whether the modem is
switched off, and is the default for the interface action.
- **README, hooks README and the comments in `/etc/config/thermal-guard`
describe what the code does**: which stage actions can keep a connection
off after a reboot, what a pwm reset writes back, when `test` shows the
escalation over time, what a missing hook means per hook, what
`fan_cooling_device_type` is used for, and that `fan_governor` applies only
when no earlier governor was recorded.
- **`thermal-guard test` reports the fan mode the daemon would use.** It took
`fan_mode` as configured, so `auto` without a cooling device or `pwm`
without `pwm_full` and `pwm_idle` claimed "forcing fan to full speed", while
the daemon leaves the fan alone in both cases. It now runs the same fan
detection, which only reads sysfs.
- **A `cpu_temp_path` set in its `/sys/devices` form no longer shows the
processor among the other sensors.** Paths were compared as written, and
the sensor loops walk the `/sys/class` links. Such a path is now resolved
and compared resolved; the default and detected paths are in class form and
cost nothing extra.
- **`... cannot send a header` is logged once per fetcher.** Without `curl` it
came with every message and with every retry of the outbox, two minutes
apart. It is said again when the header was empty in between or another
fetcher takes over, and forgotten once `curl` is there.
- **Trip messages are said once each.** They shared one memory, which every
successful trip write cleared, so `device tree trips are now ...` came back
after each change of the trips. Each message now has its own, cleared when
its cause is gone: the zone found, `trip_active` valid again, the firmware
trips recorded, a write that worked.
- **The 1.2.0 entry on notifications overstated the config file.** Only `curl`
reads `notify_url` and `notify_header` from a file; `uclient-fetch` and
`wget` take the address on their command line. Since this release such an
address is refused when it carries a query string or user info (see
Changed).
- **`at_lock` is checked where it is used, not only when the configuration
loads.** 1.2.0 said every UCI path is checked again at its use site; for
`at_lock` that was not so, `tg_at` handed it to `flock` as it was. Now a path
the guard refuses falls back to `/var/lock/modem-at.lock` there as well.
- **The processor no longer shows up among the other sensors under another
name.** It was left out only when its sensor was called `cpu_thermal`. A
processor zone with another type, or a hwmon input such as `coretemp`, was
listed a second time. Now its own sensor is skipped by path, and where it is
a thermal zone, the hwmon node the kernel mirrors it as is skipped by the
zone's type. The other inputs of the same chip stay listed.
- **A `modem-temp` hook stopped at its time limit gives no reading.** Its
output was used whatever the exit status, so a hook that printed a value
and then hung still counted. Now the output is dropped when `timeout`
reports the limit (124) or the hook died of a signal (above 128: the KILL
for a hook that ignored TERM, or a BusyBox `timeout`, which reports 143),
as the hooks README already said.
- **A reading missing at stage entry no longer counts as 0.** The reference
for "no drop" and "still climbing" was stored as 0 when that reading was
missing, and a state file from before the references existed loaded them as
0. Any later reading then counted as a rise, and stage 3 of 3 could start
without one. A missing reference now stays empty, the comparison counts only
channels with a reading and a reference, and the first reading after the gap
becomes the reference, so the channel compares again as "risen since it came
back".
- **`thermal-guard test` shows what the readings would trigger, and only on
stdout.** It ran one cycle, while every stage needs two readings in a row, so
it never showed a stage. What it could do was write a `cooled down` line
(notice) into syslog and the event log when a stage was active. Now it runs
two cycles at the same moment and prints each message it would send as
`would notify (<priority>): ...`; syslog, the event log and the outbox stay
untouched.
- **Without `ip`, messages were never delivered from stage 2 of 3 on.** The
uplink check found no route, so every message went to the outbox, and the
outbox waited for a route it could never see. Nothing was logged. Now a
missing `ip` means the uplink is unknown and the message goes out at once,
with `no ip command, cannot tell whether another uplink exists, sending at
once` logged once as a warning. A missing `flock` is logged once as well
(`no flock command, AT queries run without the shared lock`); the queries
still run.
- **A stage restored after a reboot reports an action that fails.** The
restore reapplied the stage actions without looking at the result, so a
modem that stayed on or Wi-Fi that stayed up went unreported. Now each
failure is logged as crit (`stage N action '...' failed after the reboot`),
and the one restore message, sent after the actions, names what failed. The
event log gets `restoring stage N after a reboot` before the actions start,
so a daemon that dies halfway leaves a trace.
- **Handing a pwm fan back is read back.** Reset wrote the saved mode and duty
cycle without checking them. Both are read back now and a mismatch is logged
as crit. In automatic mode the duty cycle is no longer written at all: the
chip sets it itself, the value from before the takeover means nothing there,
and some drivers refuse it.
- **The status page no longer says a board without a sensor takes no action.**
The note read "The service stays idle and takes no action", while the modem
thresholds keep working as long as the modem reports a temperature. It now
says that the processor is not watched and the modem thresholds still apply
(English and German).
- **`wifi_off` no longer counts as done when netifd manages no radio.** An
empty `network.wireless` status used to confirm the action: nothing was up,
because nothing was there, and the stage reported Wi-Fi off on a device whose
radios netifd does not see. Now the action fails (`netifd manages no Wi-Fi
radio, wifi_off switched nothing off`, crit) and is notified like any failed
action. Bringing Wi-Fi back after a reset still passes, there is nothing to
bring back. The daemon also warns once when it loads a configuration that
uses `wifi_off` on such a device, so the mistake shows before the box runs
hot; a ubus error there is left to the action.
- **`thermal-guard selftest` says why it stops** when it cannot create its
scratch directory, instead of ending with 1 and no word. The
`cooling-levels` case skips on a host without `hexdump` rather than failing.
- **Handing the zone back on reset is checked.** `tg_fan_release` wrote the
governor to the zone's `policy` without reading it back. A governor the
kernel was built without, such as `power_allocator` on the Filogic kernel,
was refused by the kernel, and the zone stayed on `user_space` with the fan
at full speed and nobody told. Now a governor missing from
`available_policies` becomes `step_wise` (logged as warning), and a zone that
still reports another policy afterwards is logged as crit.
- **A deleted option kept its last value until the daemon restarted.**
Removing `notify_url` went on sending notifications, removing a threshold
kept the old threshold. Every option now returns to its default within one
cycle.
- **A persisted stage could be lost to a power cut, and a failed persist went
unnoticed.** Writing `/etc/thermal-guard/state` on a stage change and removing
it on reset now end with `sync`. A persist that cannot be written, for example
on a full or read only overlay, is logged once (`could not persist stage N to
..., it will not survive a reboot`) instead of being treated as done. The
per cycle path writes only to `/var/run` and does not sync.
## 1.5.0
### Added
- **Wi-Fi temperatures with the proprietary MediaTek driver.** `mt_wifi`, used
by the MTK vendor images of the Banana Pi R3 Mini, registers no hwmon sensor,
so the status page showed no Wi-Fi readings although the LuCI overview did.
The extra sensors now also read `CurrentTemperature` from
`iwpriv <interface> stat` for `ra0`, `rax0` and the other `mt_wifi`
interfaces, only while they are up and bounded by `timeout`, the same way
ImmortalWrt's `autocore` does it. Shown as Wi-Fi 1, Wi-Fi 2, for display only.
## 1.4.0
Where the kernel drives the fan, thermal-guard can now lower its trip points
for a hot modem instead of competing with it. Package release `1.4.0-r2`,
deployed and checked on the GL-X3000 and both Banana Pi R3 Mini.
### Added
- **Trip management (`trip_boost`, `trip_active`, `trip_boost_offset`,
`trip_dt`).** With `trip_boost 'modem'` the daemon lowers the active trips of
the thermal zone that drives the fan by `(modem - offset) - cpu`, rounded up
to 5 K and capped at 40 K, so the kernel regulator spins the fan up for a hot
modem it cannot see. Trips only ever go below the baseline, `hot` and
`critical` are never written, a missing reading holds the trips and raising
them needs three cool readings in a row. Stopping the daemon leaves them where
they are. Nothing is written unless `trip_boost` or `trip_active` is set, so
boards with a kernel-driven fan such as the GL-X3000 keep their trips. New
module `/usr/share/thermal-guard/trips.sh`, selftest cases against a planted
sysfs tree.
- **`THERMAL_ROOT`** environment variable, default `/sys/class/thermal`, for
tests only. UCI cannot change it.
- **`/var/run/thermal-guard/modem-temp`**: one line `<degrees> <unix time>
<source>`, written atomically after every good modem reading. Other programs
read the value here instead of querying the modem over AT themselves. A
missing reading leaves the file alone, so its age shows the outage.
- Deployment findings for 1.2.0 on real hardware, one section per device,
taken into the development repository unchanged.
### Changed
- **AT queries have a time limit.** `timeout 10 flock <lock> timeout 5
sms_tool …`: the outer limit covers the wait for the lock, which BusyBox
`flock` cannot bound itself, the inner one the query. Before, a hung modem or
a program sitting on the lock stopped the whole loop, stages and trip
management included. A timeout counts as a missing reading. New dependency
`coreutils-timeout`; the selftest fails where `timeout` is missing.
- **Web interface.** System → Thermal Guard, tab Fan: `trip_boost`, the
modem allowance and the switching temperatures (`trip_active`, checked with
the same rules as the service), the state of the trip management, the
`cooling-levels` from the device tree with their duty cycle, and after an
image with other device tree trips a notice with "use the firmware values" and
"keep my values". The status page shows the current trips and by how much
they are lowered. 31 new strings, German catalogue complete.
- Status file: `trip_state`, `trip_reason` (a fixed code the page translates),
`trip_zone`, `trip_base`, `trip_now`, `trip_dt`, `trip_delta`,
`trip_dt_changed`, `trip_limit`, `fan_levels`.
- Docs: README covers trip management, `modem-temp` and the dependency.
The internal deployment documents follow the new layout of the build
repositories.
- `luci-app-thermal-guard` 1.4.0, same number as the daemon.
- **`/lib/upgrade/keep.d/thermal-guard`** keeps `/etc/thermal-guard/` across a
`sysupgrade`. Before, only `/etc/config/thermal-guard` survived: the hooks
an operator placed over ssh, `matrix.env` for `matrix-notify`, and the
persisted stages were lost with every flash. Stages persisted at the time of
a flash now come back after it, the same as after a reboot; clear them before
flashing if the cause is fixed.
- The shipped configuration leaves `trip_boost` unset, which means off. An
image can then switch it on for its board at first boot with a uci-defaults
script that only sets missing options, without overriding an own setting.
- Integration tests for trip management, the hung modem and the held lock run
the daemon against a planted sysfs tree. The suite now takes about two
minutes.
- README: why this package exists, and screenshots of the status page, the
overview block and the configuration tabs on a Banana Pi R3 Mini and a
GL-X3000, in `screenshots/`.
- CI installs shellcheck 0.11.0 from its release, checked against a pinned
SHA256, instead of the Ubuntu package. Ubuntu 24.04 ships 0.9.0, which does
not know the busybox dialect, so the lint job failed on its first run on
GitHub without looking at a single line.
### Fixed
- **A package upgrade left the old daemon running.** procd keeps an instance
whose command line did not change, and `thermal-guard daemon` never does, so
after `apk add` the previous version went on running while `thermal-guard -V`
already showed the new one. Found on the GL-X3000 with 1.4.0-r1. The package
now restarts the service after an upgrade on a running system, only if it was
running. Package release `1.4.0-r2`.
## 1.3.2
### Fixed
- **`thermal-guard selftest` failed on boards with a fan chip.** The case
"nothing to read, nothing shown" assumed no hwmon fan exists; on the GL-X3000
the real `pwm-fan` is found by name and read, which is correct. The case now
runs only where no fan chip is present.
## 1.3.1
### Fixed
- **`thermal-guard selftest` worked in the live state directory.** It saved
test stages into `/var/run/thermal-guard/state` under a running daemon, which
then saw a changed `GEN` and dropped its decision ("reset during this
cycle"), placed test hooks there, and wrote its test messages to syslog. The
1.3.0 cases also emptied the event log, the incident history the status page
shows. The deployment runbook runs the selftest on every board. It now works
in a temporary directory and logs nothing. Found on the GL-MT300N-V2 right
after installing 1.3.0.
## 1.3.0
The daemon no longer touches a fan it has not been told about. Found in the
first buildroot build: a package install starts the service at once, and on a
board without a configuration the shipped `auto` could resolve to `pwm` with an
assumed polarity of `255`/`0`, which on an inverted board stops the fan in the
stage meant to force it.
### Changed
- **`fan_mode` defaults to `none`**, in the shipped configuration and in the
daemon when the option is missing. Most boards with a fan already regulate it,
and this package is a protection layer, not a regulator.
- **`pwm_full` and `pwm_idle` have no default.** `fan_mode=pwm` needs both; with
either missing the daemon logs it once and leaves the fan alone. The
configuration page requires both when `pwm` is selected.
- **`auto` never resolves to `pwm`**, only to `cooling_device` or `none`. The
cooling device carries its polarity in the device tree; a raw pwm output
needs it from the operator.
- An upgrade keeps the existing configuration. Affected is only a board that set
`auto` without a cooling device, or `pwm` without both values; the deployment
runbook lists the cases.
### Added
- **Stage actions are read back instead of assumed.** `modem_radio_off` asks the
modem `AT+CFUN?` afterwards and resends up to three times, because a
collision on the AT port swallows a command without an error. A modem that
does not confirm fails the stage, which is notified. Switching it back on at
a reset is checked the same way.
- **`modem_radio_off_at`**: `AT+CFUN=4` (flight mode, default) or `AT+CFUN=0`
(minimum function) for a modem that does not take 4. Nothing else is
accepted, because the configuration page can write every option and a free
AT command would let it reset or disable the modem.
- **`interface_down` as a stage action.** Takes `action_interface` down, or
`uplink_interface` when that is unset, and waits for netifd to report it
down. A reset brings it back up. Interface names are checked as UCI section
names, in the daemon and on the page, since they reach `ifdown` and a ubus
path; `uplink_interface` is now checked the same way.
- **The fan is shown even where another program drives it.** `fan_mode` says
what the daemon may write, the new `fan_view` in the status file what it
reads. Under `none` it reads the raw pwm output where `pwm_full` and
`pwm_idle` are set, otherwise the cooling device, otherwise the raw output
without a percentage. The raw output comes first because the kernel derives
a cooling device's `cur_state` assuming ascending `cooling-levels`; the Banana
Pi R3 Mini's descend (`<255 96 0>`), so full speed reads as state 0. The status
page and the overview show the fan whenever `fan_view` names something.
### Fixed
- **A reset only undid `modem_radio_off` at stage 2 of 3 and `wifi_off` at
stage 3**, so either action configured for the other stage stayed applied
after a clear. Each stage's configured action is now reversed.
- **The overview block showed a pwm fan as "fan step 140 of 1"** on an inverted
board, because it used the raw value against `pwm_full` as the maximum. It
now shows the percentage the daemon computes, and `fan_max` is only reported
for pwm when both polarity values are set.
- **Stage 1 of 3 promised a fan at full speed under `fan_mode=none`**, in the
notification, on the status page and in two descriptions on the configuration
page, and logged "could not force the fan" as if the stage had failed. It now
says the fan is left to its own controller and logs nothing about it.
### Translations
- German: new `Leave the fan alone` (replaces `No fan`) and `Stage 1 of 3 active:
warning, fan left to its own controller`; reworded the descriptions of the fan
mode, `pwm_full`, `pwm_idle`, `cpu_warn` and the Actions tab.
- German: `Switch the modem radio off` (replaces `Switch the modem off
(AT+CFUN=4)`, since the level is now configurable), and new `Take a network
interface down`, `network interface down`, `How the modem is switched off`
with its description, `Flight mode (AT+CFUN=4)`, `Minimum function
(AT+CFUN=0)`, `Interface to take down` with its description.
## 1.2.0
Hardening pass over the whole package, plus the corrections that came out of
testing on a Banana Pi R3 Mini, a GL-X3000 and a GL-MT300N-V2.
### Fixed
- **One-shot commands narrated the configuration into the event log.** Every
entry point runs the same validation, so `status`, `reset` and `test` each
repeated whatever it found: three `thermal-guard status` calls on a board
without a sensor produced three identical lines. The event log keeps the last
50 entries, so a monitoring check calling `status` in a loop flushed the
record of an actual incident out of it within the hour. Only the daemon
reports these now. Found during deployment on a GL-MT300N-V2.
- **A reset could be undone by the cycle it interrupted.** Reading the modem
over AT takes seconds, and a reset landing in that window was overwritten
when the cycle saved. In the worst shape the fan was forced again right after
being handed back, leaving it at full speed while the state said idle, with
no way to clear it: the release was guarded by `stage >= 0`. Resets are now
counted in `GEN` and the count is checked before acting and before saving,
and `thermal-guard reset` releases the fan unconditionally.
- **Turning `enabled` off removed the guard instead of pausing it.**
`start_service` registered no instance, so stages stayed applied, the fan
stayed forced and the status file froze with its last values while the page
kept showing an active stage. The instance now always runs and the daemon
pauses itself.
- **The fan was addressed by hwmon number.** `hwmon2` today is `hwmon1` after
an NVMe moves or a kernel changes, and the daemon would then write a duty
cycle to a different chip and report success. The fan chip is looked up by
its hwmon name.
- **`tg_fan_release` did nothing in pwm mode** unless `fan_release_command` was
set, so the fan stayed on manual full speed after a reset.
- **A failing stage action reported success.** `tg_run_action` ended in an
unconditional `return 0`, so a modem that could not be reached still counted
as switched off. It now returns what the action returned, an unknown action
name is logged, and a failed stage is notified.
- **`tg_cfg` skipped path validation and sensor detection** entirely when `uci`
was absent.
- CI checked `70_thermal-guard.js`, which was renamed to `11_` some releases
ago, so the `luci-syntax` job had been failing on a missing file.
- The rpcd ACL named the status file and the reset command but not the ubus
`file` object they are reached through, nor the `/tmp/run` path that `/var`
resolves to. Both reads and the clear button were denied for every session
that was not root.
- **Installing `luci-app-thermal-guard` as a package did not load its ACL**
(`1.2.0-r2`). The package's own `postinst` replaced the one `luci.mk`
provides, which is the one that reloads rpcd, so the pages were refused until
rpcd restarted. The own `postinst` is gone; the default drops the menu caches
as well. Found in the first buildroot build of either package.
### Added
- **Protection stages survive a reboot.** A stage change is mirrored to
`/etc/thermal-guard/state` and reapplied at startup. The state used to live
only in `/var/run`, which is tmpfs, so any reboot silently cleared the
stages and the box came back with the modem enabled and the same broken fan.
- **`pwm_idle`**, the raw value meaning slowest, as the counterpart to
`pwm_full`. The pair carries the polarity, which several boards run inverted
(`1` full speed, `255` stopped). The fan percentage on the status page is
computed from it instead of assuming a rising scale.
- **A SoC sensor is looked for** when `cpu_temp_path` does not read, covering
ramips and x86 boards that report through hwmon rather than a thermal zone.
- **"This device reports no temperature at all"** as a state of its own, told
apart from a wrong path and shown on the status page. Some boards, the
GL-MT300N-V2 among them, expose no sensor whatsoever.
- **A second fan controller is detected.** When a value the daemon wrote has
been replaced, it logs which `fan_mode` avoids the fight, reasserts and
reports it to the page.
- The status file carries `now`, `interval`, `enabled`, `no_sensor`,
`fan_percent`, `fan_foreign` and `cpu_src`, which lets the page tell running,
paused and stopped apart instead of showing a stale snapshot as current.
- `tests/run-integration.sh`, exercising reset, the reboot restore, a garbled
state file and the collectd filter through the real scripts.
### Changed
- **Notifications go out over HTTP.** `notify_url` is posted to with `curl`
where present and `uclient-fetch` otherwise; `notify_header` carries an
authorisation token where `curl` is installed. Both go through a config file
rather than the command line, because `/proc/*/cmdline` is readable by every
local process, and both are rejected if they contain anything that could
turn that config file into further directives.
- **Custom code lives in `/etc/thermal-guard/hooks/`** as executables, not in
UCI as strings. The rpcd ACL grants write access to every option in this
configuration, so a shell command stored there was a way for anyone who
could reach the configuration page to run code as root. `sh -c` no longer
appears in the package at all.
- Paths taken from UCI are checked against the subtree they belong to, in
`tg_cfg` and again at each use site, and the config view validates the same
prefixes.
- `thermal-guard-collectd` passes status values through an integer filter
before building a `PUTVAL` line.
- A cooling device that no thermal zone binds is usable; the zone is only
needed to take the device away from a governor. `cooling_device` is preferred
where available because `max_state` means maximum cooling whichever way the
device tree runs its `cooling-levels`, so that mode cannot get the polarity
wrong.
- Reload is a no-op. `tg_cfg` runs every cycle, so a changed option is live
within one interval, and restarting would drop a stage action in flight.
- The stage banner names the configured action instead of the default, so a
box with `stage1_action=wifi_off` no longer claims the modem was switched
off.
- German catalogue regenerated: 124 entries, 34 of them new, 11 stale ones
removed.
### Documented
- **What this package is for.** It is a protection layer, not a fan controller,
and where a board already has one `fan_mode=none` is the normal setting
rather than a workaround. The built-in fan handling is for boards with
nothing else.
- **Sharing the modem's AT port.** Overlapping AT queries return nothing
useful and neither side reports a fault. Deploying next to a fan controller
that queried the modem without a lock garbled that controller's reading,
collapsed its control temperature and left the fan at its minimum on a board
at 68 °C. The symptom was at the fan, the cause at the serial port.
- **`fan_mode=pwm` is not a regulator**, now a warning in the deployment
runbook. Below the thresholds it writes nothing to the fan. Pausing the Banana
Pi's `fan-control` in favour of it left `pwm1` at a stale minimum while the
SoC climbed from 58 to 68 °C.
- **Deployment runbook, gaps found on hardware.** Check for an installed
package (`apk info -e` / `opkg status`) and remove it through the package
manager before deleting files by hand; the Banana Pi carried 1.1.0 as apk
packages. The migration now lists the options this repository removed in
1.2.0 (`notify_command` and the other `*_command` options) with their
replacements, not only the BananaWRT variant's. `pwm_idle='255'` is set on
the Banana Pi, and the runbook separates what a missing value does:
`fan_percent` pinned at 100 % under `fan_mode=pwm`, empty under
`fan_mode=none`.
- **Whether there is a kernel backstop at all.** Preferring `cooling_device`
used to be justified by the kernel continuing to regulate while the guard is
idle. That only holds where a thermal zone actually binds the cooling device,
which several boards do not do, and the README now says how to check.
### Removed
- `notify_command`, `stage1_command`, `stage2_command`, `modem_temp_command`
and `fan_release_command`. The first is replaced by `notify_url`, the next
three by hooks of the same name, and the last by recording what the pwm chip
was set to before the takeover and writing it back on release.
## 1.1.0
- Configuration page under System, clear button on the status page
- Other board temperature sensors reported alongside SoC and modem
- Fan mode no longer reset to `auto` on every cycle
## 1.0.0
- Staged overheating protection: force the fan, modem radio off, Wi-Fi off
- Status page, overview block and collectd feed

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
<https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, see <https://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General

# thermal-guard
Overheating protection for OpenWrt routers with staged mitigation.
![Status page on a Banana Pi R3 Mini](screenshots/status-bpi-r3-mini.png)
## Why this exists
The idea for this project came after a fan malfunction on my Banana Pi R3 Mini
damaged its Fibocom FM350-GL 5G module beyond repair. An inexpensive part
failed and took a much pricier one with it. Since one of my BPI R3 Minis runs
in a motorhome, I did not want to go through that again and set out to build
something that prevents it. This package is the result.
A better fan controller would not have helped: the one on the board was
convinced it had the fan at full speed. What was missing was something that
ignores what the fan is supposed to be doing and only looks at the temperature.
**This is not a fan controller.** OpenWrt has several of those and they do the
job better: they map temperature onto a curve and keep the box in its normal
band. This one does nothing at all until a threshold is crossed, and then does
something drastic that does not undo itself. Thermostat and thermal fuse, two
layers rather than two opinions.
So where a fan controller is already installed, leave it in charge: `fan_mode`
is `none` by default, and that is the regular configuration for such a board,
not a workaround. The built-in fan handling exists for boards that have nothing else,
and "force it to maximum" is a poor substitute for a curve. What this package
adds is the layer above: the one that assumes the controller can fail, or can
be wrong, and acts on the temperature rather than on what the fan reports.
A fan that stops is rarely noticed until something dies. `thermal-guard` watches
SoC and modem temperature and, when the box runs hot, escalates in three stages:
| Stage | Default action | Triggered by |
|---|---|---|
| 1 of 3 | Warning; fan forced to full speed where `fan_mode` lets the daemon drive it | `cpu_warn` or `modem_warn` reached |
| 2 of 3 | Modem radio off (`AT+CFUN=4`) | `cpu_crit`/`modem_crit`, or stage 1 held for `hold_minutes` without any drop |
| 3 of 3 | Wi-Fi off | `cpu_emergency`, or stage 2 held for `hold_minutes` while still climbing |
The web interface counts stages from one, the daemon and the status file count
them from zero, so stage 1 of 3 is `stage=0` in `thermal-guard status`. What
stages 2 and 3 do is configurable; the table shows the defaults. Each built in
action is read back rather than assumed: the modem is asked for its state
(`AT+CFUN?`), `interface_down` waits for netifd to report the interface down,
`wifi_off` waits for netifd to report no enabled radio up. An action that does not
confirm counts as failed, and the failure is notified. A `command` hook counts
by its exit code.
Three design decisions worth knowing before you deploy it:
* **Stages never roll back on their own.** Cooling down is reported once, the
stage stays. A fan that failed once will fail again, and a silent recovery
hides the fault. Clearing is an operator decision: `thermal-guard reset`.
* **A reboot does not clear them either.** A stage change is mirrored to
`/etc/thermal-guard/state`, and the daemon reapplies it at startup. The box
did not get a new fan while it was down, so coming back up with the modem
enabled would just repeat the incident. The restore is logged and notified.
* **A crash leaves the fan running.** The daemon only hands the fan back on an
explicit reset, so dying mid-incident is the safe direction.
If a restored stage ever locks you out, reach the box over a wired port or
serial and run `thermal-guard reset`. Only a device that reached a stage whose
action is `wifi_off` or `interface_down` (stage 3 of 3 with the defaults) comes
back from a reboot with that connection still off, and such a device has a fan
and a modem, so it has wired ports too.
Every transition needs two consecutive readings above the threshold, which keeps
sensor glitches from triggering anything. A missing reading never blocks an
escalation: at a threshold it simply does not count, on the hold path it counts
as no drop, so it never delays stage 2 of 3, and a reference missing at stage
entry is taken from the first reading after the gap.
Escalating from stage 1 of 3 on time alone, when the temperature has not dropped, is
the part that earns its keep. The guard never asks whether the fan turned; it
asks whether the box got cooler. That covers a fan that failed, a fan cable
that came off, and the case that prompted this package: a fan controller whose
pwm polarity was configured the wrong way round, which stopped the fan while
reporting that it had gone to full speed. No software can tell those apart on
a board without a tachometer, and none of them have to be told apart, because
the answer is the same. Set `hold_minutes` with that in mind: it is how long a
stage is given to prove it worked before the next one starts.
## Screenshots
The status page on two boards: a Banana Pi R3 Mini with a Fibocom modem, an NVMe
drive and the MediaTek vendor Wi-Fi driver, where another program drives the fan,
and a GL-iNet GL-X3000 with a Quectel modem, where the kernel does. Wi-Fi 1 and 2
come from `iwpriv` on the one and from hwmon on the other.

## Install
```sh
opkg install thermal-guard luci-app-thermal-guard # or: apk add ...
/etc/init.d/thermal-guard enable
/etc/init.d/thermal-guard start
```
Two LuCI pages: **Status → Thermal Guard** shows the temperatures, the fan and
the current stage, and clears the stages; **System → Thermal Guard** edits the
configuration. A changed option is picked up within one interval, and a
deleted one is back at its default by then, so Apply needs no restart.
The package depends on `coreutils-timeout`: every AT query runs under a time
limit, so a hung modem costs one reading instead of the whole loop. It also
depends on `jsonfilter` to read netifd's answers; `base-files` ships it on every
image anyway. Optional runtime helpers, none of them a hard dependency:
`sms_tool` for the modem AT commands, `flock` for the AT lock, `ip` for the
uplink check, and `curl` for notification headers. Without `flock` the AT
queries run without the lock; without `ip` the daemon cannot tell whether a
route exists and sends every message at once instead of queueing it. Each is
logged once as a warning.
## Configuration
`/etc/config/thermal-guard`, section `main`. Defaults leave the fan alone and
read a Quectel or Fibocom modem; driving the fan is an explicit choice.
| Option | Default | Meaning |
|---|---|---|
| `enabled` | `1` | Pauses the checks when `0`; stages and the fan stay until a reset |
| `interval` | `20` | Seconds between readings, minimum 5 |
| `cpu_warn` / `cpu_crit` / `cpu_emergency` | `70` / `80` / `90` | SoC thresholds in °C, must be ordered |
| `modem_warn` / `modem_crit` | `80` / `88` | Modem thresholds in °C |
| `hold_minutes` | `3` | How long a stage must persist before time alone escalates |
| `hysteresis` | `10` | Degrees below the warn thresholds that count as cooled down |
| `extra_sensors` | `1` | `0` hides the board's other sensors (Wi-Fi, ethernet phys, NVMe) from the status page |
| `cpu_temp_path` | `/sys/class/thermal/thermal_zone0/temp` | Sysfs source under `/sys/class/thermal/` or `/sys/class/hwmon/`, degrees or millidegrees. A sensor is looked for when this does not read |

### Fan modes
`cooling_device` sets the cooling device to its maximum step, taking the thermal
zone off its governor first if one drives it. Prefer this mode wherever the
board offers it: `max_state` means maximum cooling whichever way the device tree
runs its `cooling-levels`, so this mode cannot get the polarity wrong.
On reset the zone gets back the governor it had before, or `fan_governor` when
none was recorded. A governor the running kernel does not list in the zone's
`available_policies` is replaced by `step_wise`. The policy is read back
afterwards: a zone that still reports another one is logged as `crit`, since
then nothing regulates the fan.
A cooling device that no thermal zone binds still works, there is simply nothing
to take over and nothing to hand back. Whether one is bound is worth knowing,
because it decides whether there is a kernel backstop underneath at all:
```sh
ls /sys/class/thermal/thermal_zone*/cdev* 2>/dev/null || echo "no zone drives any cooling device"
```
Where nothing is printed, the device tree defines no `cooling-maps`, the zone's
trip points fire into nothing, and the only regulation on the board is whatever
runs in userspace. That is worth fixing in the device tree, because it is the
difference between a fan controller that can fail safely and one whose failure
nobody catches until this package escalates.
`pwm` writes the duty cycle to sysfs directly. Use it on boards where the fan is
not wired into a thermal zone. Before taking the chip over, the daemon records
its mode and duty cycle. Reset writes the mode back, and the duty cycle where
the chip was in manual mode; in automatic mode the chip sets it itself. Nothing
has to be configured for the way out. Leaving `pwm_path` empty is fine: the fan chip is
looked up by its hwmon name, which survives the renumbering that happens when
another sensor appears.
Polarity is not something the daemon can work out, and getting it wrong stops
the fan in an emergency instead of speeding it up. Several boards, the Banana Pi
R3 Mini among them, run the signal inverted: `1` is full speed and `255` stops
the fan. So there is no default: `pwm` needs both `pwm_full` and `pwm_idle`, and
with either missing the daemon logs it once and leaves the fan alone. For the
same reason `auto` never resolves to `pwm`. Confirm the values by ear rather
than by reading the number.
If another service already controls the fan, keep `fan_mode` at `none`. Stage
1 of 3 is then a warning only. Setting a fan mode anyway works: the daemon notices when a value it wrote has been replaced, says so in the log and
reasserts, but two controllers writing one file is worth avoiding, and the
other one almost certainly has the better curve. Nothing is lost: the stage
that forces the fan is the one a working controller has already covered, and
the stages that matter come after it.
### Trip management
Where the kernel drives the fan through a thermal zone, it only compares the
CPU against the zone's trip points; a modem running hotter than the CPU does not
reach it. With `trip_boost 'modem'` the daemon lowers the zone's active trips by
```
delta = (modem - trip_boost_offset) - cpu, 0 if negative,
rounded up to 5 K, at most 40 K
```
which is the same as regulating on `max(cpu, modem - offset)`, but leaves the
regulator in the kernel. The zone is the one whose `cdevN` points at the fan's
cooling device, the trips are the `active` ones bound to it, whatever their
numbers are. `hot` and `critical` are never written.
The trips only ever go below the baseline, never above it. A wrong modem reading
can therefore only make the fan louder, not slower. A missing reading keeps the
trips where they are, raising them again takes three cool readings in a row, and
not at all while a stage is in force. Stopping the daemon leaves them as they
are; setting `trip_boost 'off'` with `trip_active` unset hands the zone its
device tree values back once and leaves it alone from then on.
Nothing is written unless `trip_boost` or `trip_active` is set, so a board whose
fan the kernel already drives keeps its trips as they are.
A new firmware image can bring other trips in its device tree. The first cycle
with `trip_active` set records the device tree values of that boot in
`/etc/thermal-guard/trip_base`, which survives a sysupgrade. When a later boot
finds other values, the log says so, the status file carries
`trip_dt_changed=1`, and **System → Thermal Guard** offers to use the new values
or to keep your own. `trip_active` stays in force until you decide. Both
choices run `thermal-guard trips-keep`, which records the values of the running
boot. Without `trip_active` the file is neither read nor written.
### Sharing the modem with another program
A modem answers two overlapping AT conversations with nothing useful, and the
program that gets the nothing rarely says so. This daemon takes `at_lock` around
every query. **Anything else on the box that talks to the same port has to take
the same lock**, or both readings become unreliable. ModemManager cannot, see
the known limitations below.
That is not a theoretical concern. On a Banana Pi R3 Mini this package was
installed next to a fan controller that queried the modem without a lock. The
collisions garbled the controller's modem reading, its control temperature
collapsed, and it set the fan to its minimum while the board sat at 68 °C.
Nothing in either program reported a fault: the fan controller believed it was
regulating correctly, and this daemon believed the fan was somebody else's
business. The symptom appeared at the fan, the cause was at the serial port.
If the other program cannot be changed, give it the modem and set
`modem_source` to `none` here, but understand the cost. A modem die runs
appreciably hotter than the SoC, commonly by 10 to 20 K, so protecting it
through the processor thresholds alone means acting late for the part that is
actually at risk. Prefer fixing the lock.
Programs that only need the temperature do not have to ask the modem at all.
After every good reading the daemon writes one line to
`/var/run/thermal-guard/modem-temp`:
```
47 1790150400 at
```
degrees, Unix time of the reading, source (`at`, `file` or `command`). The file
is replaced atomically and not touched when a reading fails, so a reader that
finds it older than three intervals should treat the value as unknown.
### Notifications
Set `notify_url` and the message is posted there as the request body. That
covers ntfy, Gotify, Matrix, Slack and most other things you would want to be
woken by, and it needs no shell command in the configuration to do it.
```
option notify_url 'https://ntfy.sh/my-topic'
```
`curl` is used when it is installed, otherwise `uclient-fetch` from the OpenWrt
base, or `wget`. Only `curl` can send `notify_header`, and only `curl` reads the
address and the header from a file (mode 600) instead of the command line, where
`/proc` shows them to every local process.
Without `curl` the daemon therefore refuses an address that carries a query
string or user info (`?token=...`, `user:pass@host`). It logs the reason once
and sends nothing over HTTP; the notify hook below still works. A secret in the
path of the address, as in Slack or Discord webhooks or a private ntfy topic,
cannot be told apart from an ordinary path and is sent as it is. Without `curl`
it is visible in the process list while the message goes out. Install `curl`
for such services.
For a delivery HTTP cannot express, put an executable at
`/etc/thermal-guard/hooks/notify`; it gets the text on stdin. With both set,
the URL is tried first and the hook is the fallback.
From stage 2 of 3 on the daemon checks whether a route exists that does not run
through the modem; if not, the message is queued and retried, because that
stage is about to switch the modem off.
### Hooks
`/etc/thermal-guard/hooks/` holds executables the daemon runs for `notify`,
for `stage1` and `stage2` when the action is `command`, and for `modem-temp`
when `modem_source` is `command`. See the `README` installed in that directory.
The whole of `/etc/thermal-guard/` is listed in `/lib/upgrade/keep.d/`, so
hooks and any files they need, persisted stages and `trip_base` survive a
`sysupgrade`.
Every hook runs under a time limit: 15 s for `notify`, `stage1` and `stage2`,
5 s for `modem-temp`, which runs every cycle. A hook still running then gets
TERM, and KILL 5 s later, and counts as failed.
They are files rather than options because the rpcd ACL that lets the web
interface edit this configuration does not grant write or execute access to
that directory. Custom code therefore has to be put there by someone with
shell access, and editing the configuration cannot introduce any.
## Commands
```sh
thermal-guard status # current stage, readings, fan state
thermal-guard reset # clear all stages, hand the fan back, radio on
thermal-guard trips-keep # record this boot's device tree trips in trip_base
thermal-guard test 85 70 # two cycles with these readings, print what they would trigger, change nothing
thermal-guard selftest # run the decision logic against its test cases
```
`test` runs its two cycles at the same moment, because every stage needs two
readings in a row. The hold time does not pass in between: from an idle state,
stage 3 of 3 shows only through `cpu_emergency`, and the escalation over time
cannot be tried this way. `test 75 66` staying at stage 1 of 3 says nothing
about it. On a box already in a stage, its hold timers apply.
`/var/run/thermal-guard.status` holds a machine readable snapshot. Everything
else reads that file, so only the daemon talks to the modem, and `thermal-guard
reset`, which switches the radio back on under `at_lock`.
## Where the readings show up
* **Status -> Thermal Guard** is the monitor page: temperatures, fan state, stage.
* **Status -> Overview** gets a short temperature block, installed with the LuCI app.
* **Syslog**, tag `thermal-guard`, facility `daemon`: `crit` for a stage, a
restored stage, a stage that cannot be persisted and every stage action that
failed, the way back after a reset included; `warning` for a rejected option,
a missing tool, a sensor that does not read and trips that could not be
written; `notice` for cooled down, reset, `trips-keep` and new firmware trips
that need a decision; `info` for the rest. `logread -e thermal-guard` shows
them all, a remote syslog can filter on the priority. The event log in
`/var/run/thermal-guard/log` keeps the same lines without it.
* **Other sensors** of the board (`extra_sensors`, on by default): every hwmon and
thermal zone temperature besides the processor, such as Wi-Fi chips, ethernet
phys and NVMe drives. The proprietary MediaTek Wi-Fi driver `mt_wifi` exposes
none of those; its radios are read with `iwpriv <interface> stat` instead, the
way ImmortalWrt's own overview does it, and only while the interface is up.
These readings are shown only, they never trigger a stage.
* **RRD graphs** through collectd. The package ships an exec plugin feed, enable it
in `/etc/collectd.conf`:
```
LoadPlugin exec
<Plugin exec>
Exec "nobody:nogroup" "/usr/libexec/thermal-guard-collectd"
</Plugin>
```
Needs `collectd-mod-exec` and `collectd-mod-rrdtool`. It emits
`temperature-soc`, `temperature-modem`, `gauge-fan_step` and `gauge-stage`
under the plugin name `thermal_guard`.
## Hardware
Developed against two boards, which is where the two fan modes come from:
| Board | Fan | Modem |
|---|---|---|
| GL.iNet GL-X3000 (MT7981) | kernel thermal zone, `cooling_device` | Quectel RM520N-GL |
| Banana Pi R3 Mini (MT7986) | sysfs PWM, `pwm` | Fibocom FM350-GL |
Nothing in the package is board specific, any OpenWrt device with a readable
thermal zone should work.
## Known limitations
**ModemManager does not know `at_lock`.** It keeps the modem's AT ports open
and sends its own commands without taking the lock this daemon uses. The daemon
cannot detect that. Where ModemManager manages the modem, read the temperature
another way (`modem_source` `file` or `command`) or set it to `none`; the
section on sharing the modem says what `none` costs.
**Without `curl`, notifications are limited.** `uclient-fetch` and `wget` cannot
send `notify_header`. The message goes out without it, a webhook that needs it
refuses the message, and it stays in the outbox, retried every two minutes.
Both tools also take the address on their command line, where `/proc` shows it
to every local process while the message goes out. An address with a query
string or user info is refused for that reason and logged once; a secret in the
path of the address cannot be told apart and is sent as it is.
**A board that reports no temperature gets no processor protection.** When
neither a thermal zone nor a hwmon sensor can be read, the daemon logs `this
device reports no temperature at all, nothing to watch here` once and the
status page says so. No stage can start from the processor side. The modem
thresholds still apply as long as the modem gives a reading.
**`wifi_off` sees only what netifd manages.** The action runs `wifi down` and
confirms it through `ubus call network.wireless status`. Radios that netifd
does not manage are neither switched by `wifi` nor seen by the check. When
netifd lists no radio, the action fails and is notified, and the daemon warns
once when it loads a configuration that uses `wifi_off`. When netifd does not
answer, the action fails as well.
**Two cooling devices of the same type cannot be told apart.** The daemon
takes the first one of `fan_cooling_device_type` whose `max_state` is above 0.
If your board has such a setup, please report it.

define Package/thermal-guard/description
Watches SoC and modem temperature and escalates in stages when a router runs
hot, typically after a fan failure: fan to full speed, modem radio off, Wi-Fi
off. Stages do not roll back on their own, clearing them is an operator
decision, and they survive a reboot. Fan control works either through the
kernel thermal zone or through sysfs PWM, modem temperature through Quectel or
Fibocom AT commands, a file or a hook script. Warnings are posted to a URL.
Where the kernel drives the fan, it can lower the fan's trip points while the
modem runs hotter than the CPU.

Hooks for thermal-guard
=======================
Executables placed here run as root when the matching action fires. They are
files rather than configuration options on purpose: the LuCI page may edit
every option in /etc/config/thermal-guard, but it cannot write into this
directory, so nothing changed through the web interface can introduce code
that runs as root.
Put a hook here over SSH and make it executable (chmod 0755). A hook that is
missing or not executable is skipped: for stage1 and stage2 the daemon logs
that the action could not be carried out, a missing notify hook means no
delivery that way, and a missing modem-temp hook means no modem reading.
notify Receives the message text on stdin. Only needed for a delivery
that notify_url cannot express, a local mailer for example.
When notify_url is set as well, it is tried first and this hook
is the fallback.
stage1 Runs when stage 2 of 3 starts and stage1_action is 'command'.
stage2 Runs when stage 3 of 3 starts and stage2_action is 'command'.
modem-temp Runs when modem_source is 'command'. Has to print the modem
temperature in whole degrees Celsius on stdout, nothing else.
Every hook runs under a time limit: 15 seconds for notify, stage1 and stage2,
5 seconds for modem-temp, which runs every cycle. A hook still running then
gets TERM, and KILL 5 seconds later. It counts as failed: a stage action is
reported as not carried out, a modem-temp hook as no reading. Keep hooks short;
a mail or HTTP call inside one needs its own, shorter time limit.
Example, a notify hook for a local mailer:
#!/bin/sh
exec mail -s "thermal-guard" root
