mod_compat_roles: Fix attempt to index a nil value #1847
permissions[] is not a map with role names as keys since 817bc9873fc2
but instead a level with host names were added. This was likely an
oversight.
Refactored towards railroad.
This module lets you block connections to remote servers at the s2s
level.
``` {.lua}
modules_enabled = {
-- other modules --
"s2s_blacklist",
}
s2s_blacklist = {
"proxy.eu.jabber.org",
}
```
