mod_cloud_notify_encrypted: Ensure body substring remains valid UTF-8
The `body:sub()` call risks splitting the string in the middle of a
multi-byte UTF-8 sequence. This should have been caught by util.stanza
validation, but that would have caused some havoc, at the very least causing
the notification to not be sent.
There have been no reports of this happening. Likely because this module
isn't widely deployed among users with languages that use many longer UTF-8
sequences.
The util.encodings.utf8.valid() function is O(n) where only the last
sequence really needs to be checked, but it's in C and expected to be fast.

--- labels: - 'Stage-Alpha' summary: Security Labels ... Introduction ============ This module implements [XEP-0258: Security Labels in XMPP], but not actual policy enforcement. See for example [mod_firewall] for that. Configuration ============= As with all modules, you enable it by adding it to the modules\_enabled list. These options exist: Name Description Default ------------------------- ----------------------- ------------- security\_catalog\_name Catalouge name "Default" security\_catalog\_desc Catalouge description "My labels" You can then add your labels in a table called security\_labels. They can be both orderd and unorderd, but ordered comes first. ``` {.lua} security_labels = { { -- This label will come first name = "Public", label = true, -- This is a label, but without the actual label. default = true -- This is the default label. }, { name = "Private", label = "PRIVATE", color = "white", bgcolor = "blue" }, Sensitive = { -- A Sub-selector SECRET = { -- The index is used as name label = true }, TOPSECRET = { -- The order of this and the above is not guaranteed. color = "red", bgcolor = "black", } } } ``` Each label can have the following properties: Name Description Default ---------------- --------------------------------------------------------- ---------------------------------------------------------- name The name of the label. Used for selector. Required. label The actual label, ie `<esssecuritylabel/>` Required, can be boolean for a empty label, or a string. display The text shown as display marking. Defaults to the name color, bgcolor The fore- and background color of the display marking None default Boolean, true for the default. Only one may be default. false
