Fixes, Oper Oversight and Quality-of-Life Improvements!

Lots of quality-of-life fixes, improved oversight for opers, and a proposed channel renaming command!

With this release, we're moving to a proper Github organisation, becoming more consistent with other IRCds, and introducing a bunch more snomasks. In addition, when setting DLINE and KLINE bans, you can also kill all clients who match the ban by supplying the parameter ANDKILL when you set the ban.

Channel LIST filtering is now more useful, and I'll keep expanding this in future releases. As well, there's been some useful extensions to WHOIS, and a bug with SANICK fixed thanks to @lbeziaud. @enckse has also added Oragono to the Arch AUR, to make it easier to install on that distro.

Thanks to everyone for suggesting improvements and reporting issues! There's a lot to do as we move forward, and I have a pretty decent plan of where to go next.

Added

• Added proposed channel rename capability draft/rename.
• Send a bunch more server notice masks, now including:
  • j: Channel registration.
  • k: Kills, including those resulting from DLINEs and KLINEs.
  • n: Nick changes.
  • o: Clients opering-up.
  • q: Clients quitting.
  • u: Account registration and login.
  • x: Setting and removing DLINE/KLINE.

Changed

• DLINE and KLINE: Added ANDKILL parameter to also kill all clients that match the ban.
• LIST: Implement extended list conditions U (which filters the channels by user count).
• Renamed a number of dependency libraries, and changed Oragono to its' own organisation (only useful if you're building Oragono from source).
• WHOIS: Show the target's real IP address if you're whoising yourself or you're an oper.
• WHOIS: Show whether the target has connected securely using TLS.

Removed

• Removed the JOIN 0 command (matching what InspIRCd has done here), since this is easily abusable.

Fixed

• SANICK works properly now (thanks @lbeziaud!).

Debugging, Fixes, and Realtime Monitoring

Debugging! Fixes! Better realtime monitoring!

This release isn't too exciting, but packs large improvements to how we handle floods and similar issues. As well, the introduction of snomasks (take a look at /HELPOP snomasks) should help opers keep a basic view over their server during use. Only the "c" (connects) snomask is active right now, but others will be added and extended in future releases.

Config Changes

• Added debug section containing additional debug settings.
• Added modes key on oper config, for setting modes on oper-up.
• Added ability to log to stdout in logger methods.

Added

• Added ability to log to stdout.
• Added ability to use StackImpact profiling.
• Added initial server notice masks (snomasks).

Changed

• Socket code rewritten to be a lot faster and safer.
• Updated account registration to use the latest proposed syntax (now being /ACC REGISTER instead of /REG CREATE).

Fixed

• Clients now timeout properly if they don't complete connection registration.
• Word wrapping (with draft/maxline) no longer randomly drops characters.

Patch release to fix another bug!

This is a patch release of Oragono to fix discovered bugs and crashes. Yes, another one! I'll be implementing some more stringent checks to push releases after this, to ensure these same sort of bugs don't happen again.

Security

• Fixed a bug where any user joining an unregistered channel was given chanop status (thanks @vegax87).

Fixed

• Fixed a number of various crashes and races.

Patch release to fix a bug

This is a quick patch release of Oragono to work around a discovered bug.

Security

• Fixed a bug where non-logged in users could register channels. Bleh.

ChanServ, Logs, and Stability

This release brings channel registration with ChanServ, logging improvements, and a whole host of improvements across the board.

Thanks to a suggestion by dp- on our channel (#oragono on Freenode), the socket handling code has been overhauled to allow for a larger number of more stable connections. As well, improved testing has brought with it a bunch of strange hang and crash fixes, which means that Oragono should be more stable than ever.

Channel registration is really cool. Essentially, you register the channel with /CS REGISTER as you would on any network, and then all topic changes, the +b/+e/+I lists, and your founder status, are all remembered and re-applied when the server's restarted.

Config Changes

• channels section added to control channel registration.
• logging key under server removed, replaced with logging section.
• max-sendq key added under server.
• registration and authentication-enabled keys moved under accounts section.
• samode capability added to oper capabilities.
• sts section added under server.

Added

• Added ChanServ service, to allow channel registration.
• Added USERHOST command (thanks @vegax87).
• Added SAMODE command.
• Added draft IRCv3 capability draft/sts.

Changed

• DLINE and KLINE now let you specify years, months and days (e.g. 1y12m30d) in durations.
• Logging is now much more useful, displays colours and can log to disk.
• Socket handling has been rewritten, which means we should support more connections more effectively (thanks dp- for the suggestion!).

Fixed

• Fixed a bunch of small hangs and crashes.
• Fixed an account issue where clients could login to multiple accounts at once.
• Fixed an issue where server times were incorrect (thanks @martinlindhe!).
• Fixed halfops not being able to talk during moderated mode (+m).
• Fixed issues that prevented rehashing after the first rehash had gone through successfully.
• Fixed the inability to view channel ban, ban exception, and invite exception lists.

KLINEs, Connection Throttling and Specifications!

We've added a ton of new features in this release! Automated connection throttling, the ability to KLINE, updated casemapping and line-length specifications.

I've also started including a new section in the changelog called Config Changes, which should help you find what you need to update across releases.

Config Changes

• enabled key added under the connection-limits section.
• connection-throttling section added under server.
• linelen section added under limits.

Added

• Added ARM build (for Raspberry PIs and similar).
• Added automated connection throttling! See the new connection-throttling section in the config.
• Added KLINE and UNKLINE commands. Complementing DLINE's per-IP and per-network bans, this lets you ban masks from the server.
• Added LUSERS command (thanks @vegax87).
• Added draft IRCv3 capabilities draft/message-tags-0.2 and draft/message-ids.
• Added proposed IRCv3 capability draft/maxline.

Changed

• Changed casemapping from "rfc7700" to "rfc7613", to match new draft spec.
• Connection limits can now be freely enabled or disabled. If updating, check the new enabled flag under the connection-limits section of the config.

Fixed

• Fixed an issue where UNDLINE didn't save across server launches.
• Removed several race conditions which could result in server panics.
• WHOIS: Multiple channels now appear in a single reply (thanks @vegax87).

Fixes, DLINEs and more fixes!

This release includes a ton of fixes, as well as the ability to ban IP addresses from your network with the DLINE command!

As well, there are some major fixes with the libraries Oragono depends on, which fix various DoS attacks, crashes and timeouts. In short, this release is more stable and fixes a bunch of issues.

This release also updates the database, so be sure to run the oragono upgradedb command.

Added

• Added ability to ban IP addresses and networks from the server with the DLINE and UNDLINE commands.
• Added alpha REST API (intended primarily for use with a future web interface to manage accounts, DLINEs, etc).

Changed

• Database upgraded to make handling accounts simpler.
• Only give chanop (@) on channel join, not channel founder (~). We'll do channel founder and all on registered chans only.

Fixed

• Fix a bunch of bugs around setting nicknames on join.
• Fixed crash when using STATUSMSG-like messaging.
• Fixed crash with gIRC-Go ircmsg library we depend on.
• Fixed not sending MODE changes to all clients in a channel.
• Fixed timeout issue with go-ident library we depend on (which caused hangs on connection).
• Prevented a DoS related to lots of clients connecting at once.
• Removed races around setting and changing NICKs, to be more safe.
• Send channel NOTICEs properly.

Oper classes, ISUPPORT tokens and bugfixes

This release packs a more extensive oper privelege framework, bugfixes for capabilities/modes, support for new RP commands and more RPL_ISUPPORT tokens. In general, a bunch of new features and bugfixes to make using Oragono more smooth.

Added

• Added automatic client connection limiting, similar to other IRCds.
• Added operator classes, allowing for more finely-grained permissions for operators.
• Length of channel mode lists (ban / ban-except / invite-except) is now restricted to the limit in config.
• Roleplaying commands, both inside channels and between clients.
• Support MAXLIST, MAXTARGETS, MODES, TARGMAX in RPL_ISUPPORT.
• Added support for IRCv3 capability chghost.

Changed

• In the config file, "operator" changed to "opers", and new oper class is required.

Fixed

• Fixed being able to change modes when not an operator.
• Fixed bug where HELP wouldn't correctly display for operators, and added more help topics.
• Fixed bug where you would always have certain capabilities enabled.
• Fixed display of large MONITOR lists.

REHASH, improved listeners and mode fixes

We now support dynamically reloading the config file, along with some new IRCv3 capabilities and some fixes.

The REHASH changes are fairly extensive here, but should now be stable (this also fixes a denial of service possible with the old code).

Security

• Prevent a denial of service where the server would stop accepting connections.

Added

• Added REHASH command.
• Added ability to message channel members with a specific privelege (i.e. support for STATUSMSG).
• Added ability to enable and disable SASL.
• Added support for IRCv3 capabilities cap-notify and echo-message.

Changed

• Server operators no longer have permissions to do everything in channels.

Fixed

• MODE: Fixed issue where channel privelege changes returned incorrectly.

Much specs. Such Unicode.

Improved compatibility, more features.

Now comes with a new proper Unicode-capable casemapping and integrated help!

Added

• Added integrated help (with the /HELP command).
• Added support for IRCv3.2 capability negotiation including CAP values.
• Added support for IRCv3 capabilities account-notify, invite-notify, monitor, sasl, and draft capability message-tags as draft/message-tags.

Changed

• Casemapping changed from custom unicode mapping to preliminary rfc7700 mapping.

Removed

• Removed channel persistence with the +P mode (not too useful as currently implemented, to be replaced later).
• Removed the PROXY command (breaks our TLS user mode, and our integrated support for TLS should be fine).
