medianet's Issues

move mn_modsave cronjob into user crontab

Right now we're running as root from /etc/cron.hourly.

mn_silencer does not work

ExecStart=/usr/local/bin/mn_silencer "Starting synchronisation." /usr/bin/zita-a2j $OPTIONS
Nonetheless, there are "Starting synchronisation." messages as soon as there is no incoming TOSLINK clock. Will eventually hog a lot of log space, eliminating useful information.

wifi-rx.service does not recover from source restart

instead, it produces an endless stream of
mn-vpxp-wifi-2 mpv[20543]: [ffmpeg/demuxer] sdp: RTP: dropping old packet received too late
only recovery is by manually restarting the service.

This page has a solution for ffmpeg, but it doesn't seem to apply readily to mpv:
https://stackoverflow.com/questions/47301718/ffmpeg-rtp-streaming-errors-rtp-dropping-old-packet-received-too-late

increase JACK timeout value for robustness

under thermal-throttle conditions, zita-n2j sometimes times out, gets killed by jack and is restarted by systemd. better prevent killing in the first place.

mn_config_update fails to deal with corner case

ufw is not handled correctly by mn_config_update

it assumes it's in /medianet/systemd, but it's in the default system location. time to think about getting rid of this hack altogether - maybe the new systemd doesn't choke on symlinks anymore?

Re-implement smooth hardware fade-up to previous value after audio graph has been set up.

We should boot with hardware mixer set to -oo dB, and only fade up gently after everything is stable (don't just switch on, some stream might already be playing, and we don't want to frighten anyone).

jackd hangs with JackAudioDriver::ProcessGraphAsyncMaster process error after boot

then recovers after > 1min.

Read only: dhcp lease file

Feb 08 04:16:19 mn_29f4ff dhcpcd[517]: dhcp_bind: write_lease: Read-only file system

mpv gapless playback must be explicitly enabled

--gapless-audio=weak

shairport-sync is not announced on the network when / is mounted read-only

Looks like the root cause is with avahi rather than shairport-sync, but I'm not sure.

handle wifi-[tx|rx] config in mn_config_update

currently, we need ~/mn.sdp rtsp source description file, better embed in a "config" : [] array.

use fake-hwclock to have a sane timestamp even before ntp

see /etc/cron.hourly/fake-hwclock, man fake-hwclock

mn_config_update does not handle enabling system services

We assume all services enabled from medianet.json reside in /medianet/systemd/. That is not true for system services. This error:

May 12 20:20:25 SCLAN-network-speakers mn_config_watch[313]: Enabling ufw.service...
May 12 20:20:25 SCLAN-network-speakers mn_config_watch[313]: Failed to enable unit: File /medianet/systemd/ufw.service: No such file or directory
May 12 20:20:25 SCLAN-network-speakers mn_config_watch[313]:  failed (return code 1).

is without consequence because ufw is already enabled, but we need to fix it.
Check if service file is present in /medianet/systemd/system, otherwise don't give an explicit link path, just enable, assuming systemd knows where it is.

Image bootstrapping: factor out final "deployment step"

Currently, the bootstrapping docs will make the user create a final, deployed image. Factor out the deployment specific steps such as

set machine id
set config
set host keys
grow local partition to media size
eeprom update

and recommend the user to create a base image before performing these.

create script to turn raspbian-lite image into medianet base image

Not entirely trivial: we need to

automatically mount the image file (kpartx -a, then mount boot)
touch a file named "ssh" in /boot to enable ssh login
update kernel command line, remove fs auto-resize
resize / partition to 4G
create a third partition with ext4 data=journalled, size so that everything fits on an 8G SD card
update fstab to mount this partition rw on /local
trigger automatic bootstrapping process

ntp-sync.service sometimes takes very long

ntp-sync.service uses ntp-wait to check if ntp has settled and system time is now monotonous. This is critical for JACK when running on USB and possibly other devices, as a jump in system time will trigger a massive xrun warning that sometimes may crash the audio driver and/or JACK.
For unknown reasons, it can sometimes take several minutes to half an hour for ntp to settle (happens rarely). Since jackd.service will wait until ntp-sync pulls in the ntp-synced.target, it can appear as if the audio stack is broken.

check /etc/medianet/config.json for syntactical correctness before applying

document and automate raspbian-to-medianet bootstrapping process

create sub-directories in /medianet/sbin:
00-as-user-pi (symlinks up to first reboot)
01-as-user-medianet (up to second reboot)
02-as-user-medianet (up to third and final reboot)
99-deploy-image (only those steps needed to individualize a pre-made image: hostname, host keys, machine id etc.)

jackd.service fails because jackd.target is not deployed by anything

it's neither part of mn_set_systemd_services nor the mn_config_update mechanism.

dpl.lv2 custom build installs to / rather than /medianet/overlay

/etc/hosts does not resolve local hostname correctly

the old mn_set_hostname should be removed. the new jq routine sets /etc/hostname correctly, but fails to resolve the local hostname to 127.0.0.1 in /etc/hosts correctly. This prevents the system from being bootstrapped.

mn_config_update should only write files if settings have actually changed

Currently, we're hitting the flash a bit often... mn_modsave already does it properly.

example config fails to boot on pi3

the culprit seems to be arm_freq=1500, get rid of that one!

USB audio interface dies when filesystems are remounted read-only

Not a problem in production, but still odd.

bootstrapping process fails at mn_add_package due to missing /etc/resolv.conf link target

no idea yet why that happens. another reboot before that step fixes the issue.

Underclock production RPis to reduce temperature and power consumption

arm_freq=1000
in MHz allows for arbitrary upper limits of CPU speed. Run comparative tests re CPU temperature and power usage!

add config option to keep persistent syslog

we should have an option to keep the systemd journal in /local/data/log and/or push it to a remote syslog host.

Custom builds: optimisations to global variable, make platform-dependent

Currently, optimisation CFLAGS are hardcoded into each *.build file in custom_builds. They should be factored out into a global variable in lib/mn_includes, and chosen for each platform (Pi2, Pi3B, Pi3B+, Pi4B, max_portable).

Firewall configuration should be modular at the service level

Currently we have a global, fixed firewall configuration that always opens all ports of all prototyped services. It would be more elegant and more secure to configure open ports in a more modular, fine-grained fashion via the medianet.conf file.

consider setting ~medianet to /medianet

would enable some user configuration (git --global user.{email,name}) to be committed and saves some typing during development work, because /home/medianet is not a very interesting place to be...

camera module not loaded when using medianet configurator

The Pi camera is enabled by adding

start_x=1
gpu_mem=128

to /boot/config.txt, which works.
When using the medianet.json mechanism to enable the camera, they get added to /boot/medianet.txt instead. Despite being included by /boot/config.txt, the settings are not applied.

Might be an upstream issue. Kernel has been upgraded to 5.4.35-v7+ because of driver errors with the standard kernel 4.19.97-v7+ (but the config.txt issue also exists in 4.19.97-v7+), and the problem happens both on an RPi 3B+ and 4.

Workaround for now: hardcode the options in config.txt.

logrotate fails due to /var/lib/logrotate/status.tmp

mpv.service does not honor jackName JSON setting

For some reason, the Environment variable does not get expanded, and we end up with --jackname="$JACKNAME" (literally)

monitor undervoltage/throttling events

The kernel keeps track of previous undervoltage or high-temperature throttling events:

We should use this.

RPi3B+ with externally powered USB interface sometimes does not reboot cleanly...

... or only after a long time. Check if back-powering is an issue.

CPU frequency setup is broken on RPi 3B+

We cannot reliably under-clock the RPi 3B+ using cpufreq-set. Investigate other ways of setting clocks, check existing systemd services, retire our own?

jconvolver configuration is missing from mn_config_update

we should generate a config file, kernels would still have to be copied into /etc/medianet/jconvolver.

mn_make_image fails with new buster image due to size change

dd padding with a fixed number of bytes is not robust... repartitioning fails.

zita-n2j does not reconnect after network cable was pulled

When the ethernet is pulled, zita-n2j stops. After reconnecting, systemd resurrects the job, but since we currently leave mod-host in charge of the connections, there is no sound afterward.
Long-term fix would be to let each service handle its up- and downstream connections... easily done by hand for a fixed setup, but kinda messy for an automatically provisioned system...

mn_config_update shouldn't need empty options: "" to work correctly

Currently, if the "options": "..." line is not present, the entire service.d directory is not written out.

Firewall rules should be per-feature

Currently, we have one static ufw config. Instead, rules should be added on a per-service level as defined in medianet.json. Maybe mixture of app profiles with port lists and custom rules for e.g. "limit to local subnet".

reimplement mn_config_watch using systemd.path

...for consistency with mn_tunnel and to consolidate.

move boot/ to overlay/...

... for cleaner directory structure, re-use and improve mn_set_default_config copy mechanism and exclusion from mn_deploy_overlay linkage (clean up the latter with an explicit list of not-to-be-linked targets).

mn_config_update does not handle connections target units missing in config.json correctly.

Here is a configuration where mod-host has four outputs, two of which go to a missing (not: disabled) unit:
CONNECTIONS_OUT="effect_9:outL
system:playback_1
effect_9:outR
system:playback_2
effect_9:outL
effect_9:outR
"
Note the last two lines, they will result in a connection error since both are source ports.
Maybe improve the jq includes to generate extra newlines, so that it's more obvious that something is missing.
If one port were undefined instead of two, all further connections down the line would be mangled, so this bug is kinda serious if not affecting stability of correctly configured systems.

handle jconvolver config in mn_config_update

currently we hard-link this/jconvolver.conf, should be handled by standard "config": [ ] array.

custom_builds: resolve dependencies

Currently, custom_builds that depend on other custom_builds will fail. To fix this, two issues will have to be solved:

builds need to state what their dependencies are
builds either need to make sure their deps are deployed to the system, or better yet check inside /medianet/overlay.

mn_modsave error when no previous state file exists

mn_modsave[893]: cat: /local/data/mod-host.state: No such file or directory
