I am actually on a freeze, because I really do not know what to make of the situation with the static LSM interface.
There is a grave problem with chaining, because you cannot specify the activation order of one or more LSMs with compiled-in code!
Some kernel Makefiles even contain hints "this depends on link order" (e.g. net/ipv6/netfilter/Makefile) - and I bet for sure that this will also be the case for LSM. No thanks.
While we are at it, consider the hypothethical case of a production server, and the boss tells you to switch to $ThatLSM, with no downtime. After all, it worked when $Company switched to $ThisLSM with Linux 2.6.x ∀ x<24.
