Using systemd's `Delegate=` option, it is possible to get it to let you manage your own cgroup subtree, therefore allowing you to set options and other fun stuff.
This commit adds support for doing so and configuring the resource limits in config.toml.
For later: The cgroup created has to be a threaded one. Iin theory, we can actually wait for the QEMU process to handshake qmp, grab the vCPU threads, and only limit those. For now, just limiting the entire QEMU process works, though and is the least complicated.
NOTE: Windows support should still work, even if you have resource limits configured. If you do, it should only warn and complain, but still function.
IMPORTANT:
This commit contains new config options.
Make sure your local config file is up to date with config.example.toml to avoid issues.
CHANGELOG:
- Fix crash exploit caused by abnormally long WebSocket messages
- Added config option for limiting the maximum amount of active connections from the same IP
- Made per-IP turn limiter configurable
- Fixed an issue where vote updates were not sent to clients in some cases
- Added warning about using qmpSockDir on Windows hosts
- Updated dependencies
- Removed unused code/imports
The previous default of 5 messages is utterly lame and didn't provide enough context to anything, and was also a downgrade from the old server as that had 10 messages by default (of which we're now going back to with this change).
* Add IPData, Windows support, bugfixes
Changes:
- Added IPData: mutes and votes are now tracked per-IP instead of per-user.
- Windows support: QMP over TCP can now be enabled in the config.
- Vote cooldown can now be specified in the config.
- Fixed bugs:
"Username is already taken" message appearing when it shouldn't
* Remove vote from closed connections
