| #define DBUS_MAXIMUM_ARRAY_LENGTH (67108864) |
Max length of a marshaled array in bytes (64M, 2^26) We use signed int for lengths so must be INT_MAX or less.
We need something a bit smaller than INT_MAX because the array is inside a message with header info, etc. so an INT_MAX array wouldn't allow the message overhead. The 64M number is an attempt at a larger number than we'd reasonably ever use, but small enough that your bus would chew through it fairly quickly without locking up forever. If you have data that's likely to be larger than this, you should probably be sending it in multiple incremental messages anyhow.

| #define DBUS_MAXIMUM_NAME_LENGTH 255 |
Max length in bytes of a bus name, interface, or member (not object path, paths are unlimited).
This is limited because lots of stuff is O(n) in this number, plus it would be obnoxious to type in a paragraph-long method name so most likely something like that would be an exploit.

| #define DBUS_MINIMUM_HEADER_SIZE 16 |
The smallest header size that can occur.
(It won't be valid due to missing required header fields.) This is 4 bytes, two uint32, an array length. This isn't any kind of resource limit, just the necessary/logical outcome of the header signature.
