When proposing internal method calls on multisigs, ID address must be used

[whyrusleeping]

I attempted to use a stable address in a call to an internal multisig method (via propose). When it executed, i got an exit code 8, which implies the caller check failed. I think this is because it checked the ID address against the actor address and failed out.

If this is true, we should probably normalize these down at runtime.

To clarify: you proposed a transaction with To being the stable address of the multisig actor itself? Which method was it?

The multisig does normalize all externally-provided addresses (I think even on the v0.9 branch). It does not attempt to normalize rt.Receiver() or rt.Caller() though because the VM is supposed to only provide already-normalized addresses (otherwise actors would have to do a lot more normalization calls).

// Can only be called by the multisig wallet itself.
rt.ValidateImmediateCallerIs(rt.Receiver())

It sounds like you ran into filecoin-project/lotus#3589, which I desperately hope will be fixed with the next upgrade.

filecoin-project/lotus#3589 has landed, please lmk if you have trouble even after that.
