- bitcoind: Remove obsolete defaultText
- clightning: Fix description
Option `address` can't be used to specify a socket path because it's
used explicitly as an IP address in many places.
- lnd: Break up overlong line
This is required by commit `services: support 0.0.0.0/:: in `address` options`
- nix-bitcoin.nix: Formatting
- secrets: Improve descriptions
Benefits of adding top-level variables for used services:
- Makes it obvious which other services are referenced by a service
- Less code
We already do this in many other places.
These are insignificant, generic options; place them above readonly options.
We already do this in other services.
Also move user/group config to bottom in spark-wallet.
This greatly improves readability and makes it easier to discover options.
This commit was genereated by running the following script inside the
repo root dir:
#!/usr/bin/env ruby
def transform(src)
return false if src.include?('inherit options;')
success = false
options = nil
src.sub!(/^ options.*?^ }.*?;/m) do |match|
options = match
" inherit options;"
end
return false if !options
src.sub!(/^with lib;\s*let\n+/m) do |match|
success = true
<<~EOF
with lib;
let
#{options}
EOF
end
success
end
Dir['modules/**/*.nix'].each do |f|
src = File.read(f)
if transform(src)
puts "Changed file #{f}"
File.write(f, src)
end
end
`generate-secrets` is no longer a monolithic script. Instead, it's
composed of the values of option `nix-bitcoin.generateSecretsCmds`.
This has the following advantages:
- generate-secrets is now extensible by users
- Only secrets of enabled services are generated
- RPC IPs in the `lnd` and `loop` certs are no longer hardcoded.
Secrets are no longer automatically generated when entering nix-shell.
Instead, they are generated before deployment (via `krops-deploy`)
because secrets generation is now dependant on the node configuration.
- btcpayserver: remove unneeded trailing semicolons
- krops/get-sha256:
`tail` is unneeded because `nix-prefetch-url` just outputs a single
line containing the hash.
Now that service uid, gid mappings are included in the backups, along
with the service data dirs, we can remove 'chown -R' for
clightning and liquidd data dirs.
Note that we used 'chown -R' only for these two services, while this
approach would have been relevant for all services with data dirs.
nix-bitcoin.nix is now no longer dependent on clightning.nix and lnd.nix.
Due to condition '!(config.services ? clightning)' lnd.nix still
doesn't depend on clightning.nix.
Also fix the assertion message by renaming clightning.bindPort to clightning.port.
NixOS option `security.hideProcessInformation` for globally restricting
access to /proc has been removed.
Use per-service restrictions via 'ProtectProc' instead.
Rename
`nix-bitcoin.security.hideProcessInformation` to
`nix-bitcoin.security.dbusHideProcessInformation`
because this option now only implements the dbus restriction.
Starting with 0.21.0, bitcoin no longer automatically creates and loads
a default wallet.
This was being ignored because of a JoinMarket issue [1] in CI builds prior
to this version. Now a watch-only Bitcoin Core wallet is created in ExecStartPost.
[1] https://github.com/JoinMarket-Org/joinmarket-clientserver/issues/812
Don't copy bitcoin-rpcpassword-privileged as root, instead run service
with group "bitcoin".
Same effect, less complexity. Note, PoLP still obeyed for joinmarket-ob-watcher.
Due to a possible NixOS bug, this commit has no effect on NixOS 20.09
where `RestrictAddressFamilies` is a no-op.
It's only relevant for NixOS unstable with cgroups v2.
bitcoind+zmq: instead of allowing all address families, only add the required
AF_NETLINK family.
lnd: lnd only runs a zmq client, not a server, therefore it requires
no additional address families.
lightning-pool, clightning-plugin-zmq: add AF_NETLINK.
- Improve readability by using minutes
- set `TimeoutStopSec` like in bitcoin/contrib/init/bitcoind.service.
Stopping bitcoind can exceed the default timeout during IBD.
Keeping the secrets dir read-only is more simple and robust.
- lnd seed mnemonic creation and joinmarket wallet creation can be
run as the regular service user instead of root.
- It is easier to switch to a third-party secrets deployment
method in the future.
Don't create a seed mnemonic for lnd when a wallet exists.
This avoids creating unused mnemonics and helps simplifying
the migration command in `versioning.nix`.
- Fail at evaluation when secrets setup is not configured.
Previously, bitcoind failed at runtime due to the missing secrets target.
- Fail at evaluation when conflicting secrets setup methods are used.
This happens when `secretsSetupMethod` has more than one definition.
With krops or nixops the secrets target is always restarted during
the deployment process.
This previously caused unnecessary restarts of all nix-bitcoin services.
Move this feature from a module preset to a regular option, so that it's
easily discoverable and accessible.
Simplify the implementation of `generateSecrets` by adding it to the
existing `setup-secrets` service script.
Also rename option setup-secrets -> setupSecrets.
This commit fixes an issue with LND, in which if both
nix-bitcoin.onionServices.lnd.public &
services.lnd.restOnionService.enable were enabled, one would try to
create a file named `lnd` and the other would try to create a directory
named `lnd` with a file named `lnd-rest` inside it. This would obiously
cause an error and fail the LND service.
When running as root, use runuser instead of sudo.
As opposed to sudo or doas, runuser is a standalone
binary that needs no external configuration.
Also, it's a bit faster.
Use the following order of definitions for all services:
- assertions
- configuration of other services
- environment.systemPackages
- tmpfiles
- own service
- users
- secrets
Journal entries now look like
`joinmarket-yieldgenerator[9795]: User data location: /var/lib/joinmarket`
instead of
`bash[9795]: User data location: /var/lib/joinmarket`
DynamicUser simplifies services that don't need a persistent uid/gid,
like joinmarket-ob-watcher.
For existing installations the data dir migration to dynamic users
is automatically handled by systemd.
- Fix jm-wallet-seed being globally readable.
- Handle seed extraction failures.
If seed extraction fails, remove the newly created wallet.
This guarantees that wallets always have an accompanying seed.
Systemd's `Description` option is a misnomer (as confessed by `man systemd.unit`):
Its value is used by user-facing tools in place of the unit file name, so this option
could have been more aptly named `label` or `name`.
`Description` should only be set if the unit file name is not sufficient for naming a unit.
This is not the case for our services, except for `systemd.services.nb-netns-bridge`
whose description has been kept.
As an example how this affects users, weird journal lines like
```
nb-test systemd[1]: Starting Run clightningd...
```
are now replaced by
```
nb-test systemd[1]: Starting clightning.service...
```
Previously, onionAddresses definitions in onionServices were of the form
onionAddresses.access.<service> = [<service>];
This caused failures for configurations where a service user name was
overridden or for bitcoind whose default user is 'bitcoin' instead of 'bitcoind'.
Now set the equivalent of:
onionAddresses.access.<actualServiceUser> = [<service>];
Implement this via a new option `onionAddresses.services` to make things more
readable and to work around an infinite recursion error in onionServices.
- enable usage outside of secure-node.nix
- use json as the output format
- show ports
- also show local addresses, which is particularly useful when
netns-isolation is enabled
- only show enabled services
Move 'enforceTor' and onion-service definitions from secure-node.nix.
Use the onionServices module to define onion services.
Onion services now automatically work for services that bind to an INADDR_ANY (`0.0.0.0`) address.
- use -e to check for existence of /var/lib/tor/state, use shorter
polling interval
- clear existing dataDir contents to avoid accumulating obsolete data
- use concatMapStrings instead of foldl'
