-Subject: [PATCH] util: Limit size of wl_map
-
-Since server IDs are basically indistinguishable from really big client
-IDs at many points in the source, it's theoretically possible to overflow
-a map and either overflow server IDs into the client ID space, or grow
-client IDs into the server ID space. This would currently take a massive
-amount of RAM, but the definition of massive changes yearly.
-
-Prevent this by placing a ridiculous but arbitrary upper bound on the
-number of items we can put in a map: 0xF00000, somewhere over 15 million.
-This should satisfy pathological clients without restriction, but stays
-well clear of the 0xFF000000 transition point between server and client
-IDs. It will still take an improbable amount of RAM to hit this, and a
-client could still exhaust all RAM in this way, but our goal is to prevent
-overflow and undefined behaviour.
-
-Fixes #224
