mod_smacks: fix bug for missbehaving clients sending multiple acks in a row
Missbehaving clients, sending multiple acks in a row (I'm looking at you Monal!)
triggered the ack-loop-prevention code added in 2017, leaving unacked stanzas
in the queue. This fixes the bug while still preventing ack-loops.

Introduction ============ On a server with public registration it is usually desirable to prevent registration of certain "reserved" accounts, such as "admin". This plugin allows you to reserve individual usernames, or those matching certain patterns. It also allows you to ensure that usernames conform to a certain pattern. Configuration ============= Enable the module as any other: modules_enabled = { "block_registrations"; } You can then set some options to configure your desired policy: Option Default Description -------------------------------- --------------- ------------------------------------------------------------------------------------------------------------------------------------------------- block\_registrations\_users `{ "admin" }` A list of reserved usernames block\_registrations\_matching `{ }` A list of [Lua patterns](http://www.lua.org/manual/5.1/manual.html#5.4.1) matching reserved usernames (slower than block\_registrations\_users) block\_registrations\_require `nil` A pattern that registered user accounts MUST match to be allowed Some examples: block_registrations_users = { "admin", "root", "xmpp" } block_registrations_matching = { "master$" -- matches anything ending with master: postmaster, hostmaster, webmaster, etc. } block_registrations_require = "^[a-zA-Z0-9_.-]+$" -- Allow only simple ASCII characters in usernames Compatibility ============= ----- ------------- 0.9 Works 0.8 Should work ----- -------------
