mod_http_oauth2: Limit revocation to clients own tokens in strict mode
RFC 7009 section 2.1 states:
> The authorization server first validates the client credentials (in
> case of a confidential client) and then verifies whether the token was
> issued to the client making the revocation request. If this
> validation fails, the request is refused and the client is informed of
> the error by the authorization server as described below.
The first part was already covered (in strict mode). This adds the later
part using the hash of client_id recorded in 0860497152af
It still seems weird to me that revoking a leaked token should not be
allowed whoever might have discovered it, as that seems the responsible
thing to do.

**NOTE:** XMPP compression has unresolved [security concerns](https://mail.jabber.org/pipermail/standards/2014-October/029215.html), and this module has been removed from Prosody and renamed. While the bandwidth usage of XMPP isn't that much, compressing the data sent to/from your server can give significant benefits to those on slow connections, such as dial-up or mobile networks. Prosody supports compression for client-to-server (if your client supports it) and server-to-server streams using the mod\_compression plugin. # Details mod\_compression implements [XEP-0138], and supports the zlib compression algorithm. ## Dependencies The XMPP protocol specifies that all clients and servers supporting compression must support the "zlib" compression method, and this is what Prosody uses. However you will need to install zlib support for Lua on your system. There are different ways of doing this depending on your system. If in doubt whether it is installed correctly, the command `lua -lzlib` in a console should open a Lua prompt with no errors. Debian/Ubuntu : `apt-get install lua-zlib` LuaRocks : `luarocks install lua-zlib` Source : <https://github.com/brimworks/lua-zlib> # Usage ``` lua modules_enabled = { -- Other modules "compression_unsafe"; -- Enable mod_compression_unsafe } ``` ## Configuration The compression level can be set using the `compression_level` option which can be a number from 1 to 9. Higher compression levels will use more resources but less bandwidth. ## Example ``` lua modules_enabled = { -- Other modules "compression_unsafe"; -- Enable mod_compression_unsafe } compression_level = 5 ```
