This updates balena lint to the latest version to enable eslint support
and unblock Typescript updates. This is a huge number of changes as the
linting rules are much more strict now, requiring modifiying most files
in the codebase. This commit also bumps the test dependency `rewire` as
that was interfering with the update of balena-lint

RPI firmware configuration allows repeating overlays to define
configurations on multiple devices. For instance, for configuring
multiple `ads` devices, `config.txt` needs to be setup this way
```
dtoverlay=ads1115,addr=0x48
dtoverlay=ads1115,addr=0x49
```
Before this change, the supervisor would interpret both lines as
belonging to the same overlay, preventing users from configuring multiple
devices, and leading to a loop when trying to apply configurations with
repeated overlays coming from the cloud side.

This commit completes the list of default / board-wide dtparams
to include some `baudrate` and `vc` i2c params.
Change-type: patch

Previously, getBootConfig() of the config.txt backend was omitting
array configurations such as gpio settings, thus resulting in the SV
mistakenly assuming that boot config had not been applied, since gpio
would not be in current config.txt config but would be in target config.
This resulted in SV entering an infinite loop of attempting to apply the
gpio config when it wasn't necessary.

While ordering is important in the RPI firmware configuration file (config.txt),
some dt params are by default considered part of the base dt overlay
if they are not used by other overlays.
Unfortunately the [list of dtparams](https://github.com/raspberrypi/firmware/blob/master/boot/overlays/README#L133)
is too long to add all of them as exceptions, but we can add the params
used in the default config.txt provided in OS images, to avoid reboots
when updating to this new supervisor and correctly parsing the
provisioning config.txt as variables.
While this addition handles most common scenarios, there is still a
chance a user may have use other base overlay dt params in the initial
config, in which case those will be interpreted according to the
relative ordering

PR #2217 removed the expose configuration but also caused a regresion
where ports set via the `ports` configuration would no longer get
exposed to the host, despite portmappings being set. This fixes that

It's not an official status from container inspects, and the Supervisor
doesn't set it internally anywhere. It's better to remove it entirely as the
method by which Supervisor sets internal service statuses is by using a global
event emitter (reportNewStatus) which makes things difficult to test.

The previous implementation in #2170 of parsing the container status was too general,
because it relied on the mistaken assumption that a container would have a status of
`Stopped` if it was manually stopped. This turned out to be untrue, as manually stopped
containers were also getting restarted by the Supervisor due to their inspect status of
`exited`. With this, parsing the exit message became unavoidable as there are no other
clear ways to discern a container that has been manually stopped and shouldn't be started
from a container experiencing the Engine-host race condition issue (again, see #2170).
Since we're just parsing the exit error message, we don't need to worry about different behaviors
amongst restart policies, as any container with the error message on exit should be started.

This ensures target state has settled (since it seems that the 'applied' status
that's reported isn't 100% accurate and the actual Engine state may lag behind slightly)
Signed-off-by: Christina Ying Wang <christina@balena.io>
There exists a race condition between Engine and a host resource that may not
be immediately created. In this race condition, if a container's compose config
depends on the existence of that host resource, such as a network interface, and the
Engine tries to create & start the container before the host resource is created, the
Engine will not reattempt to start the container, regardless of the restart policy.
This is undesireable behavior but seems to be the behavior as implemented by Docker.
To rectify this, the Supervisor state funnel noops for a grace period of 1 minute
after starting a container to see that the container's status has become 'running`.
If the container exits because of the race condition, the status becomes 'exited' and the
Supervisor will attempt to generate another start step. This noop-wait-start step loop
will repeat until the container is able to start.
If the container is never able to start, there was a problem in the host in the creation of the
host resource, and that should be fixed at the host level.
This commit does not handle the case of services with restart policies "no" or "on-failure"
which encounter this host race, as metadata from container inspects needs to be introduced
during step calculation in order to figure out whether services with those restart policies
need to be started. This will be fixed in a future PR.

Devices affected by the bug described in 1576, are also stuck with some
services in the `Downloaded` state, because the state engine does not
detect that the running services should be killed on a network change
even if they belong to a new release. This is a bug, which can be
replicated by the tests in this commit

These tests use the supervisor API to check that applying a target state
allows the device to eventually get to the desired target configuration.
This are high-level tests that work with real images and containers
using dind.

The actions now work by passing an intermediate state to the state
engine.
- doPurge first removes the user app from the target state and passes
that to the state engine for purging. Since intermediate state doesn't
remove images, this will have the effect of basically re-installing
the app.
- doRestart modifies the target state by first removing only the
services from the current state but keeping volumes and networks. This
has the same effect as before where services were stopped one by one
Change-type: patch
There were multiple places in the state engine that skipped some
operations while in local mode. In reality, all it's needed while in
local mode is to skip image and volume deletion.
This commit simplifies application-manager and compose app to be more
local mode agnostic and instead making the image deletion and volume
deletion configurable via function arguments.
This also has the benefit to make the treatment of local mode
applications more similar to cloud mode applications, allowing for
API endpoints to function the same way both modes.

The OS since v2.82.6 will monitor changes to config.json and restart
the relevant services to apply the changes. There is no need to trigger
restart of the services via the supervisor. Users on older OS versions
will need to update their OS or restart the services manually as OS
loses support after 2y.

As the Supervisor is a privileged container, it has access to host /dev, and therefore has access
to boot, data, and state balenaOS partitions. This commit sets up the framework for the following:
- Finds the /dev partition that corresponds to each partition based on partition label
- Mounts the partitions into set mountpoints in the device
- Removes reliance on env vars and mountpoints provided by host's start-balena-supervisor script
- Simplifies host path querying by centralizing these queries through methods in lib/host-utils.ts
This particular changes env vars for and mounts the boot partition.
Since the Supervisor would no longer rely on container `run` arguments provided by a host script,
this change moves Supervisor closer to being able to start itself (Supervisor-as-an-app).

The issue with the original Supervisor implementation of the firewall is that
on Supervisor start, the Supervisor flushes the INPUT chain of the filter table.
This doesn't play well with services that add to the INPUT chain on startup that
may start up before the Supervisor, such as certain NetworkManager connection
profiles. This change only replaces the BALENA-FIREWALL rule in the INPUT chain,
preserving the other rules as well as their order.

We have seen a few times devices with duplicated network names for some
reason. While we don't know the cause the networks get duplicates, this
can be disruptive for updates as trying to create a container referencing a duplicate
network results in a 400 error from the engine.
This commit finds and removes duplicate networks via the state engine,
this means that even if somehow a container could be referencing a
network that has been duplicated later somehow, this will remove the
container first.
While thies doesn't solve the problem of duplicate networks being
created in the first place, it will fix the state of the system to
correct the inconsistency.
