We don't want to have to wait for the timer to expire for the updater
to make its first run. This adds a timer unit which triggers the
geoipupdate.service unit immediately, but only runs if the configured
DatabaseDirectory doesn't exist yet.
The database directory needs to be created before the
geoipupdate.service unit is activated; otherwise, systemd will not be
able to set up the mount namespacing to grant the service read-write
access.
this adds support for software defined radio (SDR) devices by SDRplay.
SDRplay provides an unfree binary library and api-service as well
as a MIT licensed adapter library for SoapySDR for integration
with many popular SDR applications.
Enforce UMask on the systemd unit to restrict the permissions of files
created. Especially the homeserver signing key should not be world
readable, and media is served through synapse itself, so no other user
needs access to these files.
Use a prestart chmod to fixup the permissions on the signing key.
In newer versions of Nix (at least on 2.4pre20201102_550e11f) the
`extra-` prefix for config options received a special meaning and the
option `extra-sandbox-paths` isn't recognized anymore. This commit fixes
it.
It doesn't cause a behavior change when using older versions of Nix but
does cause an extra newline to appear in the config, thus changing the
hash.
Using `replace-literal` to insert secrets leaks the secrets through
the `replace-literal` process' `/proc/<pid>/cmdline`
file. `replace-secret` solves this by reading the secret straight from
the file instead, which also simplifies the code a bit.
ssm-agent expects files in /etc/amazon/ssm. The pkg substitutes a location in
the nix store for those default files, but if we ever want to adjust this
configuration on NixOS, we'd need the ability to modify that file.
This change to the nixos module writes copies of the default files from the nix
store to /etc/amazon/ssm. Future versions can add config, but right now this
would allow users to at least write out a text value to
environment.etc."amazon/ssm/amazon-ssm-agent.json".text to provide
their own config.
Since v2021.5.0 home-assistant uses the ifaddr library in the zeroconf
component to enumerate network interfaces via netlink. Since discovery
is all over the place lets allow AF_NETLINK unconditionally.
It also relies on pyroute2 now, which additionally tries to access files
in /proc/net, so we relax ProtectProc a bit by default as well.
This leaves us with these options unsecured:
✗ PrivateNetwork= Service has access to the host's network 0.5
✗ RestrictAddressFamilies=~AF_(INET|INET6) Service may allocate Internet sockets 0.3
✗ DeviceAllow= Service has a device ACL with some special devices 0.1
✗ IPAddressDeny= Service does not define an IP address allow list 0.2
✗ PrivateDevices= Service potentially has access to hardware devices 0.2
✗ PrivateUsers= Service has access to other users 0.2
✗ SystemCallFilter=~@resources System call allow list defined for service, and @resources is included (e.g. ioprio_set is allowed) 0.2

→ Overall exposure level for home-assistant.service: 1.6 OK 🙂
The reap function culls expired pastes outside of the process serving
the pastes. Previously the database could accumulate a large number of
pastes and while they were expired they would not be deleted unless
accessed from the frontend.
Individual settings would previously overwrite the whole config, but
now individual values can be overwritten.
Fix missing slash to make the database path an absolute path per
https://docs.sqlalchemy.org/en/14/core/engines.html#sqlite.
Drop preferred_lexers, it's not set to anything meaningful anyway.
Home-assistant through its `--runner` commandline flag supports sending
exit code 100 when the `homeassistant.restart` service is called.
With `RestartForceExitStatus` we can listen for that specific exit code
and restart the whole systemd unit, providing an actual clean restart
with fresh processes. Additional treat exit code 100 as a successful
termination.
This is what is still exposed, and it should still allow things to work
as usual.

This can grow to as much as ~1.9 if you use one of the bluetooth or nmap
trackers or the emulated_hue component, all of which required elevated
permisssions.
This ensures that newly created secrets will have the permissions
`0640`. With this change it's ensured that no sensitive information will
be word-readable at any time.
Related to #121293.
Strictly speaking this is a breaking change since each new directory
(including data-files) aren't world-readable anymore, but actually these
shouldn't be, unless there's a good reason for it.
This is what is still exposed, and it allows me to control my lamps from
within home-assistant.

The upstream recommended minimum length for db_key_base is 30 bytes,
which our option descriptions repeated. Recently, however, upstream
has, in many places, moved to using aes-256-gcm, which requires a key
of exactly 32 bytes. To allow for shorter keys, the upstream code pads
the key in some places. However, in many others, it just truncates the
key if it's too long, leaving it too short if it was to begin
with. This adds a patch that fixes this and updates the descriptions
to recommend a key of at least 32 characters.

This version contains a vulnerability[1], and isn't maintained. The
original reason to have two jellyfin versions was to allow end-users to
backup the database before the layout was upgraded, but these backups
should be done periodically.

As the only consequence of isSystemUser is that if the uid is null then
it's allocated below 500, if a user has uid = something below 500 then
we don't require isSystemUser to be set.

This should reduce memory fragmentation drastically and is recommended
by both the Puma and the Sidekiq author. It's also the default value
for Ruby deployments on Heroku.
Fixes#112834 where incorrect documentation of options was reported.
customIni used to replace the entire default configuration while the
new settings option is merged in with the default configuration
and still allows overriding options when needed.
