- Improves readability
- `netns exec ...` (called via `netnsIptables`) incurs a large
overhead: In addition to netns switching, a mount namespace
is setup and populated with the contents of /etc/netns/<ns>/.
Instead, simply run `nsenter`.
Previously, restarting a service implied restarting its netns.
For unknown reasons, this sometimes caused the netns-local address
to not be routable from the root netns for up to 20 s.
I.e., the service was sometimes unreachable after restarting.
Now the netns is no longer stopped when the service is stopped.
This simplifies the host's address configuration.
This also removes unused addresses that are returned when resolving
container hostnames via nss-mymachines:
`getent ahosts nb-test`
- README: add matrix room
- examples/configuration.nix: explain why bitcoind is enabled by default
- btcpayserver: group lnd service settings
- clightning:
Use public onion port only when the onion service is public
This allows users to enable the onion service while announcing a
non-onion public address.
- netns-isolation: move `readOnly` attr to the top
- tests: use mkDefault to allow for easier overriding
- tests/btcpayserver: test web server response
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
Under normal circumstances, service-specific netns should never exist
before the netns setup service starts.
An existing netns is a genuine error that should not be silently ignored.
A short time after `netns delete` finishes, the peer link in the main
netns is automatically removed.
When `link del` is run before that, it fails with
`Cannot find device "nb-veth-br-*"` and the netns service enters a failed state.
- Remove redundant option mainchainrpchost.
This option is already provided by bitcoind.
- Set a working default for rpcport and rpcuser.
Enables use without secure-node.
- Explain why we don't use option `networking.bridges`
- Make the bridge setup service part of NixOS' network-setup.service.
This yields no noticable functional changes for now, but it's
conceptually cleaner to finish the network setup before network.target
becomes active.
- Add 'nb-' prefix to service name
